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

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

(h)Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made (either with its own funds or a Borrowing under Section 2.06(e)), the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of this Section to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i)Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.12(b). From and after the effective

date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of an Issuing Bank hereunder, the 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 replacement, but shall not be required to issue additional Letters of Credit.

(j)Cash Collateralization.

(i)    If any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Lenders with LC Exposure representing greater than sixty-six and two-thirds percent (66⅔%) of the total LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in the Cash Collateral Account an amount in cash equal to the total LC Exposure as of such date plus any accrued and unpaid interest thereon, if any; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (h) or (i) of Article IX.

(ii)    All cash collateral provided by the Borrower or any other Credit Party pursuant to the request of the Administrative Agent in accordance with Section 2.20(c) shall be deposited in the Cash Collateral Account.

(iii)    Deposits in the Cash Collateral Account made pursuant to either the foregoing paragraph (i) of this Section 2.06(j) or Section 2.20(c) shall be held by the Administrative Agent as collateral for the payment and performance of the Obligations under this Agreement and Borrower hereby grants a security interest in such cash and each deposit account (including the Cash Collateral Account) into which such cash is deposited to secure the Obligations under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over the Cash Collateral Account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent but in consultation with the Borrower and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with LC Exposure representing sixty-six and two-thirds percent (66⅔%) or more of the total LC Exposure), be applied to satisfy other Obligations under this Agreement and to the extent any excess remains after payment in full in cash of all Obligations and the termination of all Commitments, such excess shall be released to the Borrower.

(v)    If the Borrower is required to provide an amount of cash collateral pursuant to either paragraph (i) of this Section 2.06(j) or Section 2.20(c), the amount of such cash collateral (to the extent not applied as aforesaid) shall be returned to the Borrower within one (1) Business Day after (x) in the case of cash collateral provided pursuant to paragraph (i) above, all Events of Default have been cured or waived and (y) in the case of cash collateral provided pursuant to Section 2.20(c), the date on which such cash collateral is no longer required pursuant to Section 2.20(c).

Section 2.07Funding of Borrowings.

(a)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 12:00 noon to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to a deposit account of the Borrower designated by the Borrower in the applicable Borrowing Request; provided that ABR Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.06(e) shall be remitted by the Administrative Agent to the Issuing Bank.

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

Section 2.08Interest Elections.

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

(b)To make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.05 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in the form attached hereto as Exhibit C and signed by the Borrower.

(c)Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.04:

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 clauses (iii) and (iv) below shall be specified for each resulting Borrowing);

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

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

iv.if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period,” unless otherwise agreed upon by the Borrower and the Administrative Agent.

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

(d)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)If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Majority Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

(a)The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan on the Maturity Date.

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

(c)The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(d)The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement; and provided further that to the extent there is any conflict between the accounts maintained pursuant to paragraph (b) or (c) of this Section and the Register maintained pursuant to Section 11.04, the Register shall control.

(e)Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in the form attached hereto as Exhibit D. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 11.04) be represented by one or more promissory notes in such form payable to the payee named therein (or to such payee and its registered assigns).

(a)The Borrower shall have the right at any time and from time to time to prepay without premium or penalty any Borrowing in whole and or in part, subject to prior notice in accordance with paragraph (b) of this Section and to payment of any funding indemnification amounts required by Section 2.16.

(b)The Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 11:00

a.m., three Business Days before the date of prepayment, or (ii) in the case of prepayment of an ABR Borrowing, not later than 11:00 a.m., one Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination or reduction of the Aggregate Commitment as contemplated by Section 2.02, then such notice of prepayment may be revoked if such notice of termination or reduction is revoked in accordance with Section 2.02. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.04. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.13.

Section 2.11Mandatory Prepayment of Loans.

(a)Except as otherwise provided in clauses (b), (c), (d) and (e) of this Section 2.11, in the event a Borrowing Base Deficiency exists, the Borrower shall, within thirty (30) days after written notice from the Administrative Agent to the Borrower of such Borrowing Base Deficiency, either (i) by instruments satisfactory in form and substance to the Administrative Agent, provide additional security satisfactory to the Required Lenders in their sole discretion to eliminate such Borrowing Base Deficiency, (ii) prepay, without premium or penalty, the principal amount of the Loans (and cash collateralize any portion of such Borrowing Base Deficiency attributable to LC Exposure) in an amount sufficient to eliminate such Borrowing Base Deficiency, (iii) notify the Administrative Agent that it intends to prepay, without premium or penalty (but subject to any funding indemnification amounts required by Section 2.16), the principal amount of such Borrowing Base Deficiency in not more than five (5) equal monthly installments plus accrued interest thereon and make the first such monthly payment on the 30th day after the Borrower’s receipt of notice of such Borrowing Base Deficiency or (iv) exercise any combination of options (i), (ii) and (iii) above to eliminate such Borrowing Base Deficiency.

(b)Upon any redetermination or adjustment to the Borrowing Base as a result of a Disposition of any Borrowing Base Properties (including a Disposition of Equity Interests of a Restricted Subsidiary) pursuant to Section 7.04(j), the Borrower shall (i) prepay the Loans (and cash collateralize any portion of such Borrowing Base Deficiency attributable to LC Exposure) to the extent necessary to eliminate any Borrowing Base Deficiency that may have occurred as a result of such Disposition within one (1) Business Day of the date it or any Restricted Subsidiary consummates such Disposition, and (ii) in the case of any exchange of Borrowing Base Properties for other Oil and Gas Interests, take all actions reasonably necessary that are requested by the Administrative Agent to cause such Oil and Gas Interests received in such exchange to become additional security for the Obligations by instruments satisfactory in form and substance to the Administrative Agent.

(c)Upon any redetermination or adjustment to the Borrowing Base as a result of a Hedge Modification pursuant to Section 7.04(j), the Borrower shall prepay the Loans (and cash collateralize any portion of such Borrowing Base Deficiency attributable to LC Exposure) to the extent necessary to eliminate any Borrowing Base Deficiency that may have occurred as a result of such Hedge Modification promptly, and in any event by the later of (A) the date that is one (1) Business Day after the date it or any Restricted Subsidiary receives the Net Cash Proceeds from such Hedge Modification or (B) the date of such redetermination or adjustment to the Borrowing Base.

(d)In the event any Borrowing Base Deficiency occurs as a result of a reduction in the Borrowing Base pursuant to Section 3.05 upon an issuance of Senior Notes, the Borrower shall prepay the Loans (and cash collateralize any portion of such Borrowing Base Deficiency attributable to LC Exposure) with the Net Cash Proceeds received as a result of the issuance of such Senior Notes within one Business Day after receipt of such Net Cash Proceeds to the extent necessary to eliminate such Borrowing Base Deficiency.

(e)In the event that the Aggregate Credit Exposure exceeds the lesser of the Maximum Facility Amount and the sum of the Commitments of all the Lenders at such time, the Borrower shall immediately prepay, subject to any funding indemnification amounts required by Section 2.16, the principal amount of the Loans (and cash collateralize any such excess attributable to LC Exposure) to the extent necessary to eliminate such excess.

(f)Amounts applied to the prepayment of Borrowings pursuant to this Section shall be first applied ratably to ABR Borrowings then outstanding and, upon payment in full of all outstanding ABR Borrowings, second, to Eurodollar Borrowings then outstanding, and if more than one Eurodollar Borrowing is then outstanding, to each such Eurodollar Borrowing beginning with the Eurodollar Borrowing with the least number of days remaining in the Interest Period applicable thereto and ending with the Eurodollar Borrowing with the most number of days remaining in the Interest Period applicable thereto. Any prepayments pursuant to this Section shall be accompanied by accrued interest to the extent required by Section 2.13 and any funding indemnification amounts required by Section 2.16.

(a)The Borrower agrees to pay to the Administrative Agent, for the account of each Lender, an unused commitment fee (the “Unused Commitment Fee”) equal to the Applicable Rate times the daily average of the total Unused Commitments. Such Unused Commitment Fee shall be calculated on the basis of a year consisting of 360 days. The Unused Commitment Fee shall be payable in arrears on the last day of March, June, September and December of each year, commencing with the first such date to occur after the Effective Date, and on the Maturity Date for any period then ending for which the Unused Commitment Fee shall not have been theretofore paid. In the event the Aggregate Commitment terminates on any date other than the last day of March, June, September or December of any year, the Borrower agrees to pay to the Administrative Agent, for the account of each Lender, on the date of such termination, the pro rata portion of the Unused Commitment Fee due for the period from the last day of the immediately preceding March, June, September or December, as the case may be, to the date such termination occurs.

(b)The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Rate used to determine the interest rate applicable to Eurodollar Loans on the face amount of each Letter of Credit during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank a fronting fee for each Letter of Credit equal to 0.125% per annum on the face amount of such Letter of Credit during the period from and including the Effective Date to but excluding the later of the date of termination of the Aggregate Commitment and the date on which there ceases to be any LC Exposure (but in no event less than $500 per annum), as well as the Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable on the third Business Day following such last day, commencing on the first such date to occur after the Effective Date; provided that all such fees shall be payable on the date on which the Aggregate Commitment terminates and any such fees accruing after the date on which the Aggregate Commitment terminates shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be payable within 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(c)The Borrower agrees to pay to the Administrative Agent and J.P. Morgan Securities LLC, for their respective accounts, the fees set forth in the Fee Letter payable to the Administrative Agent and J.P. Morgan Securities LLC and such other fees payable in the amounts and at the times separately agreed upon between the Borrower, the Administrative Agent and J.P. Morgan Securities LLC.

(d)All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for distribution, in the

case of Unused Commitment Fees and participation fees, to the Lenders. Fees paid shall not be refundable under any circumstances.

(a)The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Rate.

(b)The Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate.

(c)Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section.

(d)Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Aggregate Commitment and on the Maturity Date; provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Loan prior to the end of the Availability Period at a time when no Borrowing Base Deficiency exists), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

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

Section 2.14Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

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

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

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing.

(a)If any Change in Law shall:

i.impose, modify or deem applicable any reserve, special deposit, liquidity or similar requirement (including any compulsory loan requirement, insurance charge or other assessment) 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 the Issuing Bank;

ii.impose on any Lender or the Issuing Bank or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or any Letter of Credit or participation therein; or

iii.subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto;

and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, continuing, converting or maintaining any Eurodollar Loan or Fixed Rate Loan (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender, the Issuing Bank or such other Recipient of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender, the Issuing Bank or such other Recipient hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender, the Issuing Bank or such other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender, the Issuing Bank or such other Recipient, as the case may be, for such additional costs incurred or reduction suffered.

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

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

(d)Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 2.16Break 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 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 (regardless of whether such notice may be revoked under Section 2.10(b) and is revoked in accordance therewith), (d) the assignment of any Eurodollar Loan

other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.03 or Section 2.19, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the Eurodollar market. A certifi-cate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

Section 2.17Taxes.

(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 without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Credit Party shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section 2.17) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(b)Payment of Other Taxes by the Borrower. The Credit Parties shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes.

(c)Evidence of Payments. As soon as practicable after any payment of Taxes by any Credit Party to a Governmental Authority pursuant to this Section 2.17, such Credit Party 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.

(d)Indemnification by the Borrower. The Credit Parties shall jointly and severally indemnify each Recipient, within 10 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority; provided, however, that the Credit Parties shall not be required to make any payment pursuant to this Section 2.17 if the Agent or Lender, as the case may be, makes demand for such payment more than eighteen months after the earlier of (i) the date on which the relevant Governmental Authority makes written demand upon such Person for payment of such Indemnified Taxes, and (ii) the date on which such Person has made payment of such Indemnified Taxes. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e)Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but

only to the extent that any Credit Party has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Credit Parties to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 11.04(c) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (e).

(f)Status of Lenders.

i.Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 2.17(f)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

ii.Without limiting the generality of the foregoing,

1.any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. Federal backup withholding Tax;

2.any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable:

(1)    in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN (or applicable successor form) establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN (or applicable successor form) establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(2)    executed originals of IRS Form W-8ECI;

(3)    in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit F-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed originals of IRS Form W-8BEN (or applicable successor form); or

(4)    to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN (or applicable successor form), a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-2 or Exhibit F-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-4 on behalf of each such direct and indirect partner;

3.any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. Federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and

4.if a payment made to a Recipient under any Loan Document would be subject to U.S. Federal withholding Tax imposed by FATCA if such Recipient were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Recipient shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Recipient has complied with such Recipient’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower

and the Administrative Agent in writing of its legal inability to do so.

(g)Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.17 (including by the payment of additional amounts pursuant to this Section 2.17), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 2.17 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (g) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (g), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (g) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(h)Survival. Each party’s obligations under this Section 2.17 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

(i)Defined Terms. For purposes of this Section 2.17, the term “Lender” includes any Issuing Bank and the term “applicable law” includes FATCA.

(a)The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.15, Section 2.16 or Section 2.17, or otherwise) prior to 12:00 noon on the date when due, in immediately available funds, without set‑off or counterclaim. 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 at Mail Code IL1-0010, 10 South Dearborn, Floor 07, Chicago, Illinois, 60603-2003, except payments to be made directly to the Issuing Bank as expressly provided herein and except that payments pursuant to Section 2.15, Section 2.16, Section 2.17 and Section 11.03 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)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; provided that in the event such funds are received by and available

to the Administrative Agent as a result of the exercise of any rights and remedies with respect to any collateral under the Security Instruments, the parties entitled to a ratable share of such funds pursuant to the foregoing clause (ii) and the determination of each parties’ ratable share shall include, on a pari passu basis, (x) the Lender Counterparties with respect to Lender Hedging Obligations then due and owing to each Lender Counterparty by any Credit Party (after giving effect to any netting agreements) and (y) any Lender or any of its Affiliates with respect to Cash Management Obligations then due and owing to such Lender or any of its Affiliates by any Credit Party. Excluded Swap Obligations with respect to any Guarantor shall not be paid with amounts received from such Guarantor or its assets, but appropriate adjustments shall be made with respect to payments from other Credit Parties to preserve the allocation to the Obligations otherwise set forth above in this Section.

(c)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 paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

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

(e)If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.06(d) or Section 2.06(e), Section 2.07(b), Section 2.18(d) or Section 11.03(c), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), (i) apply any amounts thereafter received by the Administrative Agent for the account of such Lender for the benefit of the Administrative Agent or the Issuing Bank to satisfy such Lender’s obligations to it under such Sections 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 under any such Section, in the case of each of clauses (i) and (ii) above, in any order as determined by the Administrative Agent in its discretion.

(a)If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, 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 2.15 or Section 2.17, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b)If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17 or if any Lender becomes a Defaulting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 11.04), all its interests, rights (other than its existing rights to payments pursuant to Sections 2.15 or 2.17) and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent (and if a Commitment is being assigned, the Issuing Bank), which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

(c)If (i) in connection with any proposed increase in the Borrowing Base or proposed amendment, modification, termination, waiver or consent with respect to any of the provisions of this Agreement or any other Loan Document that requires approval of all of the Lenders, each Lender or each Lender affected thereby under Section 11.02, the consent of the Super-Majority Lenders shall have been obtained but the consent of one or more of such other Lenders (each a “Non-Consenting Lender”) whose consent is required has not been obtained, or (ii) any Lender becomes a Defaulting Lender; then, in each case, the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, elect to replace such Non-Consenting Lender or Defaulting Lender, as the case may be, as a Lender party to this Agreement in accordance with and subject to the restrictions contained in, and consents required by Section 11.04; provided that (x) the Borrower shall have received the prior written consent of the Administrative Agent (and if a Commitment is being assigned, the Issuing Bank), which consent shall not unrea-sonably be withheld and (y) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts). A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply or, in the case of a Defaulting Lender, such Lender is no longer a Defaulting Lender.

Section 2.20Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(a)the fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Lender pursuant to Section 2.12(a);

(b)the Commitment and Credit Exposure of such Defaulting Lender shall not be included in determining whether the Super-Majority Lenders, the Required Lenders or the Majority Lenders have taken or may take any action hereunder (including any consent to any amendment, waiver or other modification pursuant to Section 11.02), provided that (i) any waiver, consent, amendment or modification otherwise requiring the consent of such Lender or each affected Lender shall require the consent of such Defaulting Lender, (ii) any waiver, consent, amendment or modification requiring the consent of all Lenders shall require the consent of such Defaulting Lender (except in respect of any increases in the Maximum Facility Amount) and (iii) the Commitment of such Defaulting Lender may not be increased or extended, nor amounts owed to such Lender reduced (except as expressly provided herein), or the final maturity thereof extended, without the consent of such Defaulting Lender.

(c)if any LC Exposure exists at the time such Lender becomes a Defaulting Lender then:

i.all or any part of the LC Exposure of such Defaulting Lender shall be reallocated among the non-Defaulting Lenders in accordance with their respective Applicable Percentages but only to the extent the sum of all non-Defaulting Lenders’ Credit Exposures plus such Defaulting Lender’s LC Exposure does not exceed the total of all non-Defaulting Lenders’ Commitments;

ii.if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall, within one (1) Business Day following notice by the Administrative Agent, cash collateralize for the benefit of the Issuing Bank only the Borrower’s obligations corresponding to such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.06(j) for so long as such LC Exposure is outstanding;

iii.if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to clause (ii) above, the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.12(b) with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized;

iv.if the LC Exposure of the non-Defaulting Lenders is reallocated pursuant to clause (i) above, then the fees payable to the Lenders pursuant to Section 2.12(a) and Section 2.12(b) shall be adjusted in accordance with such non-Defaulting Lenders’ Applicable Percentages; and

v.if all or any portion of such Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to clauses (i) or (ii) above, then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, all letter of credit fees payable under Section 2.12(b) with respect to such Defaulting Lender’s LC Exposure shall be payable to the Issuing Bank until and to the extent that such LC Exposure is cash collateralized and/or reallocated; and

(d)so long as such Lender is a Defaulting Lender, the Issuing Bank shall not be required to issue, amend, or increase any Letter of Credit, unless it is satisfied that the related exposure and the Defaulting Lender’s then outstanding LC Exposure will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance with Section 2.20(c), and any participating interests in any newly issued or increased Letter of Credit shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.20(c)(i) (and such Defaulting Lender shall not participate therein).

If (i) a Bankruptcy Event with respect to any Lender Parent shall occur following the date hereof and for so long as such event shall continue or (ii) the Issuing Bank has a good faith belief that any Lender has defaulted in fulfilling its obligations under one or more other agreements in which such Lender commits to extend credit, the Issuing Bank shall not be required to issue, amend, or increase any Letter of Credit,

unless the Issuing Bank shall have entered into arrangements with the Borrower or such Lender, satisfactory to the Issuing Bank to defease any risk to it in respect of such Lender hereunder.

In the event that the Administrative Agent, the Borrower, and the Issuing Bank each agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the LC Exposure of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment and on such date such Lender shall purchase at par such of the Loans of the other Lenders as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Applicable Percentage.

Section 3.01Reserve Report; Proposed Borrowing Base. During the period from the Effective Date until the first Redetermination after the Effective Date, the Borrowing Base shall be $415,000,000 (the “Initial Borrowing Base”). As soon as available and in any event by April 1 and October 1 of each year, beginning October 1, 2014, the Borrower shall deliver to the Administrative Agent and each Lender a Reserve Report, prepared as of the immediately preceding December 31 and June 30, respectively, in form and substance reasonably satisfactory to the Administrative Agent and prepared by an Approved Petroleum Engineer (or, in the case of the Reserve Report due on October 1 of each year, by one or more petroleum engineers employed by the Borrower), said Reserve Report to utilize economic and pricing parameters established from time to time by the Administrative Agent, together with such other information, reports and data concerning the value of the Borrowing Base Properties as the Administrative Agent shall deem reasonably necessary to determine the value of such Borrowing Base Properties. Simultaneously with the delivery to the Administrative Agent and the Lenders of each Reserve Report, the Borrower shall submit to the Administrative Agent and each Lender the Borrower’s requested amount of the Borrowing Base as of the next Redetermination Date. Promptly after the receipt by the Administrative Agent of such Reserve Report and the Borrower’s requested amount for the Borrowing Base, the Administrative Agent shall submit to the Lenders a recommended amount of the Borrowing Base to become effective for the period commencing on the next Redetermination Date.

Section 3.02Scheduled Redeterminations of the Borrowing Base; Procedures and Standards. Based in part on the Reserve Reports made available to the Administrative Agent and the Lenders pursuant to Section 3.01, the Lenders shall redetermine the Borrowing Base on or prior to the next Redetermination Date (or such date promptly thereafter as reasonably possible based on the engineering and other information available to the Lenders). Any Borrowing Base which becomes effective as a result of any Redetermination of the Borrowing Base shall be subject to the following restrictions: (a) such Borrowing Base shall not exceed the amount of the Borrowing Base requested by the Borrower, (b) such Borrowing Base shall not exceed the Maximum Facility Amount, (c) to the extent such Borrowing Base represents an increase in the Borrowing Base in effect prior to such Redetermination, such Borrowing Base must be approved by all Lenders, and (d) to the extent such Borrowing Base represents a decrease in the Borrowing Base in effect prior to such Redetermination or a reaffirmation of such prior Borrowing Base, such Borrowing Base must be approved by the Administrative Agent and Required Lenders. If a redetermined Borrowing Base is not approved by the Administrative Agent and Required Lenders within twenty (20) days after the submission to the Lenders by the Administrative Agent of its recommended Borrowing Base pursuant to Section 3.01, or by all Lenders within such twenty (20) day period in the case of any increase in the Borrowing Base, the Administrative Agent shall notify each Lender that the recommended Borrowing Base has not been approved and request that each Lender submit to the Administrative Agent within ten (10) days thereafter its proposed Borrowing Base. Promptly following the 10^th day after the Administrative Agent’s request for each Lender’s proposed Borrowing Base, the Administrative Agent shall determine the Borrowing Base for such

Redetermination by calculating the highest Borrowing Base then acceptable to the Administrative Agent and a number of Lenders sufficient to constitute Required Lenders (or all Lenders in the case of an increase in the Borrowing Base). Each Redetermination shall be made by the Lenders in their sole discretion, but based on the Administrative Agent’s and such Lender’s usual and customary procedures for evaluating Oil and Gas Interest as such exist at the time of such Redetermination, and including adjustments to reflect the effect of any Swap Agreements of the Borrower and the Restricted Subsidiaries as such exist at the time of such Redetermination. The Borrower acknowledges and agrees that each Redetermination shall be based upon the loan collateral value which each Agent and each Lender in its sole discretion (using such methodology, assumptions and discount rates as the Administrative Agent and such Lender customarily uses in assigning collateral value to Oil and Gas Interests) assigns to the Borrowing Base Properties consisting of proved reserves at the time in question and based upon such other credit factors consistently applied (including, without limitation, the assets, liabilities, cash flow, business, properties, prospects, management and ownership of the Credit Parties) as the Administrative Agent and such Lender customarily considers in evaluating similar oil and gas credits. It is expressly understood that the Administrative Agent and Lenders have no obligation to designate the Borrowing Base at any particular amounts, except in the exercise of their discretion, whether in relation to the Aggregate Commitment or otherwise. If the Borrower does not furnish all information, reports and data required to be delivered by any date specified in this Article III, unless such failure is not the fault of the Borrower, the Administrative Agent and Lenders may nonetheless designate the Borrowing Base at any amounts which the Administrative Agent and Lenders in their reasonable discretion determine and may redesignate the Borrowing Base from time to time thereafter until the Administrative Agent and Lenders receive all such information, reports and data, whereupon the Administrative Agent and Lenders shall designate a new Borrowing Base, in accordance with the other provisions of this Section.

Section 3.03Special Redeterminations. In addition to Scheduled Redeterminations, the Borrower shall be permitted to request a Special Redetermination of the Borrowing Base once between each Scheduled Redetermination and the Required Lenders shall be permitted to request a Special Redetermination once between each Scheduled Redetermination. Any request by the Borrower pursuant to this Section 3.03 shall be submitted to the Administrative Agent and each Lender and at the time of such request (or within twenty (20) days thereafter in the case of the Reserve Report) the Borrower shall (1) deliver to the Administrative Agent a Reserve Report prepared as of a date prior to the date of such request that is reasonably acceptable to the Administrative Agent and such other information which the Administrative Agent shall reasonably request, and (2) notify the Administrative Agent of the Borrowing Base requested by the Borrower in connection with such Special Redetermination. Any request by the Required Lenders pursuant to this Section 3.03 shall be submitted to the Administrative Agent and the Borrower. Any Special Redetermination shall be made by the Administrative Agent and Lenders in accordance with the procedures and standards set forth in Section 3.02; provided that no Reserve Report is required to be delivered to the Administrative Agent in connection with any Special Redetermination requested by the Required Lenders pursuant to this Section 3.03.

Section 3.04Notice of Redetermination. Promptly following any Redetermination of the Borrowing Base, the Administrative Agent shall notify the Borrower of the amount of the redetermined Borrowing Base, which Borrowing Base shall be effective as of the date specified in such notice, and such Borrowing Base shall remain in effect for all purposes of this Agreement until the next Redetermination.

Section 3.05Additional Reductions in Borrowing Base. Unless otherwise waived in writing by the Required Lenders, upon the issuance of any Senior Notes by any Credit Party pursuant to Section 7.01(g) (other than any Permitted Refinancing that extends, refinances, renews, replaces, defeases or refunds outstanding Senior Notes), the Borrowing Base then in effect shall automatically be reduced by the lesser of (a) $250 for each $1,000 in stated principal amount of such Senior Notes on the date such Senior Notes are issued (without regard to any initial issue discount) and (b) such other amount, if any, determined by the Required Lenders in their sole discretion prior to the issuance of such Senior Notes.

The Borrower represents and warrants to the Lenders that:

Section 4.01Organization; Powers. Each Credit Party is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, has all requisite power and authority to carry on its business as now conducted and, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, is qualified to do business in, and is in good standing in, every juris-diction where such qualification is required.

Section 4.02Authorization; Enforceability. The Transactions are within each Credit Party’s corporate, limited liability company or partnership powers and have been duly authorized by all necessary corporate, limited liability company or partnership and, if required, actions by equity holders. This Agreement has been duly executed and delivered by each Credit Party and constitutes a legal, valid and binding obligation of each Credit Party, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

Section 4.03Governmental Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as have been obtained or made and are in full force and effect or have been made or to be made in connection with the filing of the Security Instruments to secure the Obligations, (b) will not violate any Requirement of Law applicable to the Borrower or any Restricted Subsidiary, (c) will not violate or result in a default under any indenture, agreement or other instrument evidencing Material Indebtedness or a Material Sales Contract binding upon the Borrower or any Restricted Subsidiary or any of their respective assets, or give rise to a right thereunder to require any payment to be made by the Borrower or any Restricted Subsidiary, and (d) will not result in the creation or imposition of any Lien on any asset of the Borrower or any Restricted Subsidiary not otherwise permitted under Section 7.02.

Such financial state-ments, together with any notes and management discussions related thereto appearing in the Borrower’s Form 10-K filed with the SEC on March 11, 2014, present fairly, in all material respects, the financial position and results of operations and cash flows of the Borrower and its Consolidated Subsidiaries as of such dates and for such periods in accordance with GAAP and, except as set forth on Schedule 4.04, show all material indebtedness and other liabilities, direct or contingent of the Borrower and its Consolidated Subsidiaries as of the date thereof, including liabilities for Taxes, material commitments and Indebtedness.

(b)Since December 31, 2013, no event or circumstance which has had or could reasonably be expected to have a Material Adverse Effect has occurred.

(a)Except as otherwise provided in Section 4.15 with respect to Oil and Gas Interests, the Borrower and each Restricted Subsidiary has good title to, or valid leasehold interests in, all such real and personal property material to its business, except for (i) minor defects in title that do not, in the aggregate, interfere with its ability to conduct its business as currently conducted or to utilize such properties for their intended purposes and (ii) Liens permitted under Section 7.02.

(b)The Borrower and each Restricted Subsidiary owns, or is licensed to use, all trademarks, tradenames, copyrights, patents and other intellectual property material to its business, and the use thereof by the Borrower and such Restricted Subsidiaries, as the case may be, does not infringe upon the rights of

any other Person, except for any such infringements that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.

(a)There are no actions, suits or proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of the Borrower, threatened against or affecting the Borrower or any Restricted Subsidiary, (i) as to which there is a reasonable possibility of an adverse determination and that, if adversely determined, could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect after taking into account insurance proceeds or other recoveries from third parties actually received (other than the Disclosed Matters) or (ii) that involve this Agreement or the Transactions.

The Borrower and each Restricted Subsidiary is in compliance with all Requirements of Law applicable to it or its property, its Organizational Documents and all indentures, agreements and other instruments binding upon it or its property, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.

connection with the negotiation of this Agreement or delivered hereunder (as modified or supplemented by other information so furnished) when taken as a whole contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading as of the date made or deemed made; provided that, with respect to projected financial information, the Borrower represents only that such information was prepared in good faith based on assumptions believed to be reasonable at the time and, if such projected financial information was delivered prior to the Effective Date, as of the Effective Date.

Section 4.12Labor Matters. There are no strikes, lockouts or slowdowns against the Borrower or any of its Restricted Subsidiaries pending or, to the knowledge of the Borrower, threatened that could reasonably be expected to have a Material Adverse Effect. The hours worked by and payments made to employees of the Borrower and, to the knowledge of the Borrower, to employees of its Restricted Subsidiaries have not been in violation of the Fair Labor Standards Act or any other Law dealing with such matters to the extent that such violation could reasonably be expected to have a Material Adverse Effect.

Schedule 4.13 lists as of the Effective Date, (a) for the Borrower and each Restricted Subsidiary, its full legal name and its jurisdiction of organization and (b) for each Restricted Subsidiary, the number of shares of capital stock or other Equity Interests outstanding and the owner(s) of such shares or Equity Interests.

Section 4.14    Margin Stock. Neither the Borrower nor any Restricted Subsidiary is engaged principally, or as one of its important activities, in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U issued by the Federal Reserve Board), and no part of the proceeds of any Loan will be used to purchase or carry any margin stock or to extend credit to others for the purpose of purchasing or carrying margin stock.

Section 4.15    Oil and Gas Interests. Each Credit Party has good and defensible title to all proved reserves included in the Oil and Gas Interests (for purposes of this Section 4.15, “proved Oil and Gas Interests”) described in the most recent Reserve Report provided to the Administrative Agent (other than such proved reserves that have been subsequently disposed of in compliance with this Agreement), free and clear of all Liens except Liens permitted pursuant to Section 7.02. All such proved Oil and Gas Interests are valid, subsisting, and in full force and effect in all material respects, and all rentals, royalties, and other amounts due and payable in respect thereof have been duly paid except for such rentals, royalties and other amounts that are amounts being contested in good faith by appropriate proceedings and for which the Borrower or the applicable Restricted Subsidiary has set aside on its books adequate reserves, or except to the extent such rentals, royalties and other amounts due, if left unpaid, would not result in the loss or forfeiture of Oil and Gas Properties having an aggregate fair market value in excess of $10,000,000. Without regard to any consent or non-consent provisions of any joint operating agreement covering any Credit Party’s proved Oil and Gas Interests, such Credit Party’s share of (a) the costs for each proved Oil and Gas Interest described in the Reserve Report (other than for such proved Oil and Gas Interests that have been subsequently disposed of in compliance with this Agreement) is not materially greater than the decimal fraction set forth in the Reserve Report, before and after payout, as the case may be, and described therein by the respective designations “working interests,” “WI,” “gross working interest,” “GWI,” or similar terms (except in such cases where there is a corresponding increase in the net revenue interest), and (b) production from, allocated to, or attributed to each such proved Oil and Gas Interest is not materially less than the decimal fraction set forth in the Reserve Report, before and after payout, as the case may be, and described therein by the designations “net revenue interest,” “NRI,” or similar terms. The wells drilled in respect of proved producing Oil and Gas Interests described in the Reserve Report (other than wells drilled in respect of such proved producing Oil and Gas Interests that have been subsequently disposed of in compliance with this Agreement) (1) are capable of, and are presently, either producing Hydrocarbons in commercially profitable quantities or in the process of being worked over or enhanced, and the Credit Party that owns such proved producing Oil and Gas Interests is currently receiving payments for its share of production, with no funds in respect of any thereof being presently held in suspense, other than any such funds being held in suspense pending

delivery of appropriate division orders, and (2) have been drilled, bottomed, completed, and operated in compliance with all applicable laws, in the case of clauses (1) and (2), except where any failure to satisfy clause (1) or to comply with clause (2) would not have a Material Adverse Effect, and no such well which is currently producing Hydrocarbons is subject to any material penalty in production by reason of such well having produced in excess of its allowable production.

Section 4.16    Insurance. The certificate signed by a Responsible Officer that attests to the existence of, and summarizes, the property and casualty insurance program maintained by the Credit Parties that has been furnished by the Borrower to the Administrative Agent and the Lenders as of the Effective Date, is complete and accurate in all material respects as of the Effective Date and demonstrates the Borrower’s and the Restricted Subsidiaries’ compliance with Section 6.05.

Section 4.17    Solvency.

a.Immediately after the consummation of the Transactions and immediately following the making of the initial Borrowing, if any, made on the Effective Date and after giving effect to the application of the proceeds thereof, (1) the fair value of the assets of the Credit Parties on a consolidated basis, at a fair valuation, will exceed the debts and liabilities, subordinated, contingent or otherwise, of the Credit Parties on a consolidated basis; (2) the present fair saleable value of the real and personal property of the Credit Parties on a consolidated basis will be greater than the amount that will be required to pay the probable liability of the Credit Parties on a consolidated basis on their debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured; (3) the Credit Parties on a consolidated basis will be able to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured; and (4) the Credit Parties on a consolidated basis will not have unreasonably small capital with which to conduct the businesses in which they are engaged as such businesses are now conducted and are proposed to be conducted after the date hereof.

b.The Credit Parties do not intend to, and do not believe that they will, incur debts beyond their ability to pay such debts as they mature, taking into account the timing of and amounts of cash to be received by it and the timing of the amounts of cash to be payable on or in respect of its Indebtedness.

Section 4.18    Material Sales Contracts. No Credit Party is in default in the performance, observance or fulfillment of any of the obligations, covenants or conditions contained in any Material Sales Contract to which it is a party, except where such default could not reasonably be expected to result in a Material Adverse Effect.

Section 4.19    Common Enterprise. The successful operation and condition of each of the Credit Parties is dependent on the continued successful performance of the functions of the group of the Credit Parties as a whole and the successful operation of each of the Credit Parties is dependent on the successful performance and operation of each other Credit Party. Each Credit Party expects to derive benefit (and its board of directors or other governing body has determined that it may reasonably be expected to derive benefit), directly and indirectly, from (i) successful operations of each of the other Credit Parties and (ii) the credit extended by the Lenders to the Borrower hereunder, both in their separate capacities and as members of the group of companies. Each Credit Party has determined that execution, delivery, and performance of this Agreement and any other Loan Documents to be executed by such Credit Party is within its purpose, will be of direct and indirect benefit to such Credit Party, and is in its best interest.

Section 4.20    Anti-Corruption Laws and Sanctions. The Borrower has implemented and maintains in effect policies and procedures designed to ensure compliance by the Borrower, its Subsidiaries and their respective directors, officers, employees and agents with Anti-Corruption Laws and applicable Sanctions, and the Borrower, its Subsidiaries and their respective officers and employees and to the knowledge of the Borrower its directors and agents insofar as the same are acting on behalf of the Borrower or its Subsidiaries, (x) are in compliance with Anti-Corruption Laws and applicable Sanctions in all material respects and (y) have not and will not do business, enter into transactions or store with, purchase or receive money from, transport from, to or with, sell goods or give money to, a Sanctioned Person. None of (a) the Borrower, any

Subsidiary or any of their respective directors, officers or employees, or (b) to the knowledge of the Borrower, any agent of the Borrower or any Subsidiary that will act in any capacity in connection with or benefit from the credit facility established hereby, is a Sanctioned Person. No Borrowing or Letter of Credit, use of proceeds or other transaction contemplated by the Credit Agreement will violate Anti-Corruption Laws or applicable Sanctions.

Upon delivery of any such Counterpart Agreement to the Administrative Agent, notice of which is hereby waived by each Credit Party, such Material Restricted

Subsidiary shall be a Guarantor and shall be as fully a party hereto as if such Material Restricted Subsidiary were an original signatory hereto. Each Credit Party expressly agrees that its obligations arising hereunder shall not be affected or diminished by the addition or release of any other Credit Party hereunder.

Section 6.15Designation and Conversion of Restricted and Unrestricted Subsidiaries.

(a)Unless designated as an Unrestricted Subsidiary on Schedule 4.13 as of the Effective Date or thereafter, assuming compliance with Section 6.15(b), any Person that becomes a Subsidiary of the Borrower or any of its Restricted Subsidiaries shall be classified as a Restricted Subsidiary.

(b)The Borrower may designate by prior written notice thereof to the Administrative Agent, any Restricted Subsidiary, including a newly formed or newly acquired Subsidiary, as an Unrestricted Subsidiary if (i) immediately prior, and after giving effect, to such designation, (A) the representations and warranties of the Borrower and its Restricted Subsidiaries contained in each of the Loan Documents are true and correct in all material respects on and as of such date as if made on and as of the date of such redesignation (or, if stated to have been made expressly as of an earlier date, were true and correct in all material respects as of such date), and (B) no Default exists or would result therefrom (and the Borrower shall be in compliance, on a pro forma basis, with the covenants set forth in Section 7.13); (ii) such Subsidiary (A) is not the owner or the operator, by contract or otherwise, of any Oil and Gas Interests included in the Borrowing Base Properties and (B) is not a guarantor or the primary obligor with respect to any indebtedness, liabilities or other obligations under any Senior Notes; and (iii) the Investment deemed to be made in such Subsidiary pursuant to the next sentence would be permitted to be made at the time of such designation under Section 7.06. The designation of any Restricted Subsidiary as an Unrestricted Subsidiary shall constitute an Investment in an Unrestricted Subsidiary in an amount equal to the aggregate amount of the Borrower’s or any Restricted Subsidiary’s Investments previously made in or to such Subsidiary. Except as provided in this Section 6.15(b), no Restricted Subsidiary may be redesignated as an Unrestricted Subsidiary.

As used in this Section 7.07, “forecasted production from proved producing reserves” and “forecasted production from total proved reserves” means the forecasted production from proved producing reserves or total proved reserves, as the case may be, of each of Crude Oil and Natural Gas as reflected in the most recent Reserve Report delivered to the Administrative Agent pursuant to Section 3.01, after giving effect to any pro forma adjustments for the consummation of any Acquisitions or Dispositions since the effective date of such Reserve Report.

Each Credit Party and each Lender agrees and acknowledges that (i) the Existing Swap Agreements are Swap Agreements permitted under this Section 7.07, (ii) as of the Effective Date, the counterparty to each Existing Swap Agreement is a Lender Counterparty (or was a Lender Counterparty under and as defined in the Original Credit Agreement), (iii) the obligations of the Credit Parties under the Existing Swap Agreements are included in the defined term “Lender Hedging Obligations” and such obligations are entitled to the benefits of, and are secured by the Liens granted under, the Security Instruments, and (iv) as of the Effective Date, the aggregate notional volume of Hydrocarbons under all Swap Agreements of the Credit

Parties then in effect does not exceed the percentages of forecasted production from total proved reserves and forecasted production from proved producing reserves, as the case may be, permitted pursuant to this Section 7.07 (calculated as if a Credit Party was entering into a new transaction under a Swap Agreement on the Effective Date).

Section 7.08Restricted Payments. The Borrower will not, nor will it permit any of its Restricted Subsidiaries to, declare or make, or agree to pay or make, directly or indirectly, any Restricted Payment, except that (a) the Borrower may declare and pay dividends with respect to its Equity Interests payable solely in additional shares of its common stock, (b) any Restricted Subsidiary may make Restricted Payments to the Borrower or any Guarantor, (c) Restricted Subsidiaries may declare and pay dividends ratably with respect to their Equity Interests, and (d) so long as no Default or Borrowing Base Deficiency shall have occurred and be continuing, or shall result therefrom, the Borrower may declare and pay cash dividends with respect to its Equity Interests or make cash redemptions, repurchased or equity buy-backs of the Borrower’s Equity Interests, if after giving effect to such cash dividend, redemption, repurchase or buy-back, the Aggregate Commitment Usage is less than eighty five percent (85%).

Section 7.09    Transactions with Affiliates. The Borrower will not, nor will it permit any of its Restricted Subsidiaries to, sell, lease or otherwise transfer any property or assets to, or purchase, lease or otherwise acquire any property or assets from, or otherwise engage in any other transactions with, any of its Affiliates, except (a) in the ordinary course of business at prices and on terms and conditions not less favorable to the Borrower or such Restricted Subsidiary than could be obtained on an arm’s-length basis from unrelated third parties, (b) transactions between or among the Borrower and its Restricted Subsidiaries or between or among Restricted Subsidiaries not involving any other Affiliate, (c) transactions described on Schedule 7.09, (d) any Restricted Payment permitted by Section 7.08 and (e) Investments permitted by Section 7.06.

Section 7.10    Restrictive Agreements. The Borrower will not, nor will it permit any of its Restricted Subsidiaries to, directly or indirectly, enter into, incur or permit to exist any agreement or other arrangement that prohibits, restricts or imposes any condition upon (a) the ability of the Borrower or any Restricted Subsidiary to create, incur or permit to exist any Lien upon any of its property or assets to secure the Obligations, or (b) the ability of any Restricted Subsidiary to pay dividends or other distributions with respect to any of its Equity Interests or to make or repay loans or advances to the Borrower or any Restricted Subsidiary or to Guarantee Indebtedness of the Borrower or any Restricted Subsidiary; provided that (i) the foregoing shall not apply to restrictions and conditions imposed by law or by this Agreement or the Indenture (or any documents evidencing or relating to the issuance of any permitted Senior Notes or any Permitted Refinancing), and (ii) clause (a) of the foregoing shall not apply to (A) restrictions or conditions imposed by any agreement relating to secured Indebtedness permitted by this Agreement if such restrictions or conditions apply only to the property or assets securing such Indebtedness, (B) customary provisions in leases and other contracts restricting the assignment thereof and (C) restrictions with respect to Oil and Gas Interests that are not Borrowing Base Properties and are not included in the most recent Reserve Report delivered pursuant to Section 3.01.

Section 7.11    Disqualified Stock. The Borrower will not, nor will it permit any of its Restricted Subsidiaries to, issue any Disqualified Stock.

Section 7.12    Amendments to Organizational Documents. The Borrower will not, nor will it permit any of its Restricted Subsidiaries to, enter into or permit any modification or amendment of, or waive any material right or obligation of any Person under its Organizational Documents if the effect thereof would be materially adverse to the Administrative Agent or any Lender or violate Section 7.10.

Section 7.13    Financial Covenants.

(a)Consolidated Current Ratio. The Borrower will not permit the Consolidated Current Ratio as of the last day of any fiscal quarter ending on or after the Effective Date, to be less than 1.00 to 1.00.

(b)Leverage Ratio. The Borrower will not permit the Consolidated Leverage Ratio as of the last day of any fiscal quarter ending on or after the Effective Date to be greater than 4.00 to 1.00.

Section 7.14    Sale and Leaseback Transactions and other Off-Balance Sheet Liabilities. The Borrower will not, nor will it permit any Restricted Subsidiary to, enter into or suffer to exist any (i) Sale and Leaseback Transaction, except Sale and Leaseback Transactions in which the aggregate amount of liability incurred by the Borrower or any Restricted Subsidiary does not exceed $5,000,000 for all such Sale and Leaseback Transactions, taken as a whole, or (ii) any other transaction pursuant to which it incurs or has incurred Off-Balance Sheet Liabilities, except for (x) Swap Agreements permitted under the terms of Section 7.07 and (y) Advance Payment Contracts; provided that the aggregate amount of all Advance Payments received by the Borrower or any Restricted Subsidiary that have not been satisfied by delivery of production at any time does not exceed, in the aggregate $5,000,000.

Section 7.15    Senior Notes Restrictions. The Borrower will not, nor will it permit any Restricted Subsidiary to, except for regularly scheduled payments of interest required under the Senior Notes, directly or indirectly, retire, redeem, defease, repurchase or prepay prior to the scheduled due date thereof any part of the principal of, or interest on, the Senior Notes (or any Permitted Refinancing thereof); provided that, so long as no Default or Borrowing Base Deficiency shall have occurred and be continuing or would result therefrom, the Borrower may retire, redeem, defease, repurchase or prepay (a) the Senior Notes (or any Permitted Refinancing thereof) with the proceeds of any Permitted Refinancing permitted pursuant to Section 7.01(g) or with the net cash proceeds of any sale of Equity Interests of the Borrower and (b) the Senior Notes in an aggregate amount not to exceed $50,000,000 for the period from the Effective Date to and including the Maturity Date (including with the proceeds of Loans), provided that, in the case of this clause (b), immediately before and after giving effect to each such payment, the Aggregate Commitment Usage is less than eighty five percent (85%). The Borrower will not, nor will it permit any of its Restricted Subsidiaries to, enter into or permit any modification or amendment of the Senior Notes Documents the effect of which is to (i) increase the maximum principal amount of the Senior Notes or the rate of interest on any of the Senior Notes (other than as a result of the imposition of a default rate of interest in accordance with the terms of the Senior Notes Documents), (ii) change or add any event of default or any covenant with respect to the Senior Notes Documents if the effect of such change or addition is to cause any one or more of the Senior Notes Documents to be more restrictive on the Borrower or any of its Subsidiaries than such Senior Notes Documents were prior to such change or addition, (iii) shorten the dates upon which scheduled payments of principal or interest on the Senior Notes are due, (iv) change any redemption or prepayment provisions of the Senior Notes, (v) alter the subordination provisions, if any, with respect to any of the Senior Notes Documents, (vi) grant any Liens in any assets of the Borrower or any of its Subsidiaries, or (vii) permit any Subsidiary to Guarantee the Senior Notes unless such Subsidiary is (or concurrently with any such Guarantee becomes) a Guarantor hereunder.

Section 8.01    Guarantee of Payment. Each Guarantor unconditionally and irrevocably guarantees to the Administrative Agent for the benefit of the Secured Parties, the punctual payment of all Obligations now or which may in the future be owing by any Credit Party (the “Guaranteed Liabilities”). This Guarantee is a guaranty of payment and not of collection only. The Administrative Agent shall not be required to exhaust any right or remedy or take any action against the Borrower or any other Person or any collateral. The Guaranteed Liabilities include interest accruing after the commencement of a proceeding under bankruptcy, insolvency or similar laws of any jurisdiction at the rate or rates provided in the Loan Documents, the Swap Agreements between any Credit Party and any Lender Counterparty and the Cash Management Agreements, as the case may be. Each Guarantor agrees that, as between the Guarantor and the Administrative Agent, the Guaranteed Liabilities may be declared to be due and payable for the purposes of this Guarantee

notwithstanding any stay, injunction or other prohibition which may prevent, delay or vitiate any declaration as regards the Borrower or any other Guarantor and that in the event of a declaration or attempted declaration, the Guaranteed Liabilities shall immediately become due and payable by each Guarantor for the purposes of this Guarantee.

Section 8.02    Guarantee Absolute. Each Guarantor guarantees that the Guaranteed Liabilities shall be paid strictly in accordance with the terms of this Agreement, the Swap Agreements and the Cash Management Agreements to which any Secured Party is a party. The liability of each Guarantor hereunder is absolute and unconditional irrespective of: (a) any change in the time, manner or place of payment of, or in any other term of, all or any of the Loan Documents or the Guaranteed Liabilities, or any other amendment or waiver of or any consent to departure from any of the terms of any Loan Document or Guaranteed Liability, including any increase or decrease in the rate of interest thereon; (b) any release or amendment or waiver of, or consent to departure from, any other guaranty or support document, or any exchange, release or non‑perfection of any collateral, for all or any of the Loan Documents or Guaranteed Liabilities; (c) any present or future law, regulation or order of any jurisdiction (whether of right or in fact) or of any agency thereof purporting to reduce, amend, restructure or otherwise affect any term of any Loan Document or Guaranteed Liability; (d) without being limited by the foregoing, any lack of validity or enforceability of any Loan Document or Guaranteed Liability; and (e) any other setoff, defense or counterclaim whatsoever (in any case, whether based on contract, tort or any other theory) with respect to the Loan Documents or the transactions contemplated thereby which might constitute a legal or equitable defense available to, or discharge of, the Borrower or a Guarantor (other than the defense of payment or performance).

Section 8.03    Guarantee Irrevocable. This Guarantee is a continuing guaranty of the payment of all Guaranteed Liabilities now or hereafter existing under this Agreement, the Swap Agreements to which any Secured Party is a party and the Cash Management Agreements, and shall remain in full force and effect until payment in full of all Guaranteed Liabilities and other amounts payable hereunder and until this Agreement, the Swap Agreements and the Cash Management Agreements are no longer in effect or, if earlier, when the Guarantor has been designated an Unrestricted Subsidiary in accordance with Section 6.15(b).

Section 8.04    Reinstatement. This Guarantee shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Liabilities is rescinded or must otherwise be returned by the Administrative Agent, any Lender or any Lender Counterparty on the insolvency, bankruptcy or reorganization of the Borrower, or any other Credit Party, or otherwise, all as though the payment had not been made.

Section 8.05    Subrogation. No Guarantor shall exercise any rights which it may acquire by way of subrogation, by any payment made under this Guarantee or otherwise, until all the Guaranteed Liabilities have been paid in full and this Agreement and the Swap Agreements are no longer in effect. If any amount is paid to the Guarantor on account of subrogation rights under this Guarantee at any time when all the Guaranteed Liabilities have not been paid in full, the amount shall be held in trust for the benefit of the Secured Parties and shall be promptly paid to the Administrative Agent to be credited and applied to the Guaranteed Liabilities, whether matured or unmatured or absolute or contingent, in accordance with the terms of this Agreement and the Swap Agreements. If any Guarantor makes payment to any Secured Party of all or any part of the Guaranteed Liabilities and all the Guaranteed Liabilities are paid in full and this Agreement and the Swap Agreements are no longer in effect, the Administrative Agent, Lenders and Lender Counterparties shall, at such Guarantor’s request, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Guaranteed Liabilities resulting from the payment.

Section 8.06    Subordination. Without limiting the rights of the Administrative Agent, the Lenders and the Lender Counterparties under any other agreement, any liabilities owed by the Borrower to any Guarantor in connection with any extension of credit or financial accommodation by any Guarantor to or for the account of the Borrower, including but not limited to interest accruing at the agreed contract rate

after the commencement of a bankruptcy or similar proceeding, are hereby subordinated to the Guaranteed Liabilities, and such liabilities of the Borrower to such Guarantor, if the Administrative Agent so requests after the occurrence and during the continuation of a Default, shall be collected, enforced and received by any Guarantor as trustee for the Administrative Agent and shall be paid over to the Administrative Agent on account of the Guaranteed Liabilities but without reducing or affecting in any manner the liability of the Guarantor under the other provisions of this Guarantee.

Section 8.07    Payments Generally. All payments by the Guarantors shall be made in the manner, at the place and in the currency (the “Payment Currency”) required by the Loan Documents and the Swap Agreement, as the case may be; provided, however, that if the Payment Currency is other than Dollars any Guarantor may, at its option (or, if for any reason whatsoever any Guarantor is unable to effect payments in the foregoing manner, such Guarantor shall be obligated to) pay to the Administrative Agent at its principal office the equivalent amount in Dollars computed at the selling rate of the Administrative Agent or a selling rate chosen by the Administrative Agent, most recently in effect on or prior to the date the Guaranteed Liability becomes due, for cable transfers of the Payment Currency to the place where the Guaranteed Liability is payable. In any case in which any Guarantor makes or is obligated to make payment in Dollars, the Guarantor shall hold the Administrative Agent, the Lenders and the Lender Counterparties harmless from any loss incurred by the Administrative Agent, any Lender or any Lender Counterparty arising from any change in the value of Dollars in relation to the Payment Currency between the date the Guaranteed Liability becomes due and the date the Administrative Agent, such Lender or such Lender Counterparty is actually able, following the conversion of the Dollars paid by such Guarantor into the Payment Currency and remittance of such Payment Currency to the place where such Guaranteed Liability is payable, to apply such Payment Currency to such Guaranteed Liability.

Section 8.08    Setoff. Each Guarantor agrees that, in addition to (and without limitation of) any right of setoff, banker’s lien or counterclaim the Administrative Agent, any Lender or any Lender Counterparty may otherwise have, the Administrative Agent, such Lender or such Lender Counterparty shall be entitled, at its option, to offset balances (general or special, time or demand, provisional or final) held by it for the account of any Guarantor at any office of the Administrative Agent, such Lender or such Lender Counterparty, in Dollars or in any other currency, against any amount payable by such Guarantor under this Guarantee which is not paid when due (regardless of whether such balances are then due to such Guarantor), in which case it shall promptly notify such Guarantor thereof; provided that the failure of the Administrative Agent, such Lender, or such Lender Counterparty to give such notice shall not affect the validity thereof.

Section 8.09    Formalities. Each Guarantor waives presentment, notice of dishonor, protest, notice of acceptance of this Guarantee or incurrence of any Guaranteed Liability and any other formality with respect to any of the Guaranteed Liabilities or this Guarantee.

Section 8.10    Limitations on Guarantee. The provisions of the Guarantee under this Article VIII are severable, and in any action or proceeding involving any state corporate law, or any state, federal or foreign bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of any Guarantor under this Guarantee would otherwise be held or determined to be avoidable, invalid or unenforceable on account of the amount of such Guarantor’s liability under this Guarantee, then, notwithstanding any other provision of this Guarantee to the contrary, the amount of such liability shall, without any further action by the Guarantors, the Administrative Agent, any Lender or any Lender Counterparty, be automatically limited and reduced to the highest amount that is valid and enforceable as determined in such action or proceeding (such highest amount determined hereunder being the relevant Guarantor’s “Maximum Liability”). This Section 8.10 with respect to the Maximum Liability of the Guarantors is intended solely to preserve the rights of the Administrative Agent, Lenders and Lender Counterparties hereunder to the maximum extent not subject to avoidance under applicable law, and no Guarantor nor any other Person shall have any right or claim under this Section 8.10 with respect to the Maximum Liability, except to the extent necessary so that none of the obligations of any Guarantor hereunder shall not be rendered voidable under applicable law.

Section 8.11    Keepwell. Each Qualified ECP Guarantor hereby jointly and severally absolutely, unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each other Credit Party to honor all of its obligations under this Agreement in respect of Swap Obligations (provided, however, that each Qualified ECP Guarantor shall only be liable under this Section 8.11 for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this Section 8.11, or otherwise under this Agreement, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). The obligations of each Qualified ECP Guarantor under this Section shall remain in full force and effect until the Aggregate Commitment has expired or terminated and the principal of and interest on each Loan and all fees payable hereunder have been paid in full and all Letters of Credit have expired or terminated and all LC Disbursements shall have been reimbursed. Each Qualified ECP Guarantor intends that this Section 8.11 constitute, and this Section 8.11 shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of each other Credit Party for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.

If any of the following events (“Events of Default”) shall occur:

(a)the Borrower shall fail to pay any principal of any Loan (including any payments required under Section 2.11) or any reimbursement obligation in respect of any LC Disbursement when and as the same shall become due and payable, whether at the due date thereof or at a date fixed for prepayment thereof or otherwise;

(b)the Borrower shall fail to pay any interest on any Loan or any fee or any other amount (other than an amount referred to in clause (a) of this Article) payable under this Agreement, when and as the same shall become due and payable, and such failure shall continue unremedied for a period of three (3) Business Days;

(c)any representation or warranty made or deemed made by or on behalf of the Borrower or any Restricted Subsidiary in or in connection with this Agreement or any amendment or modification hereof or waiver hereunder, or in any report, certificate, financial statement or other document furnished pursuant to or in connection with this Agreement or any amendment or modification hereof or waiver hereunder or in any Loan Document furnished pursuant to or in connection with this Agreement or any amendment or modification thereof or waiver hereunder, shall prove to have been incorrect in any material respect when made or deemed made and such materiality is continuing;

(d)the Borrower or any Restricted Subsidiary shall fail to observe or perform any covenant, condition or agreement contained in Section 6.02, Section 6.03 (with respect to the Borrower’s or any Restricted Subsidiary’s existence), Section 6.05 (with respect to insurance), Section 6.08, or in Article VII;

(e)the Borrower or any Restricted Subsidiary shall fail to observe or perform any covenant, condition or agree-ment contained in this Agreement (other than those specified in clause (a), (b) or (d) of this Article) or any Loan Document, and such failure shall continue unremedied for a period of 30 days after receipt of written notice thereof from the Administrative Agent to the Borrower (which notice will be given at the request of any Lender);

(f)the Borrower or any Restricted Subsidiary shall fail to make any payment (whether of principal or interest and regardless of amount) in respect of any Material Indebtedness, when and as the same shall become due and payable and such failure shall continue beyond the applicable grace period, if any.

(g)any event or condition occurs that results in any Material Indebtedness becoming due prior to its scheduled maturity or that enables or permits (with or without the giving of notice, the lapse of time or both) the holder or holders of any Material Indebtedness or any trustee or agent on its or their behalf to

cause any Material Indebtedness to become due, or to require the prepayment, repurchase, redemption or defeasance thereof, prior to its scheduled maturity; provided that this clause (g) shall not apply to (i) secured Indebtedness that becomes due as a result of the voluntary sale or transfer of the property or assets securing such Indebtedness and (ii) Indebtedness that becomes due as a result of a change in law, tax regulation or accounting treatment so long as such Indebtedness is paid when due;

(h)an involuntary proceeding shall be commenced or an involuntary petition shall be filed seeking (i) liquidation, reorganization or other relief in respect of the Borrower or any Restricted Subsidiary or its debts, or of a substantial part of its assets, under any Federal, state or foreign bankruptcy, insolvency, receivership or similar law now or hereafter in effect or (ii) the appointment of a receiver, trustee, custodian, sequestrator, conservator or similar official for the Borrower or any Restricted Subsidiary or for a substantial part of its assets, and, in any such case, such proceeding or petition shall continue undismissed for 60 days or an order or decree approving or ordering any of the foregoing shall be entered;

(i)the Borrower or any Restricted Subsidiary shall (i) voluntarily commence any proceeding or file any petition seeking liquidation, reorganization or other relief under any Federal, state or foreign bankruptcy, insolvency, receivership or similar law now or hereafter in effect, (ii) consent to the institution of, or fail to contest in a timely and appropriate manner, any proceeding or petition described in clause (h) of this Article, (iii) apply for or consent to the appointment of a receiver, trustee, custodian, sequestrator, conservator or similar official for the Borrower or any Restricted Subsidiary or for a substantial part of its assets, (iv) file an answer admitting the material allegations of a petition filed against it in any such proceeding, (v) make a general assignment for the benefit of creditors or (vi) take any action for the purpose of effecting any of the fore-going;

(j)the Borrower or any Restricted Subsidiary shall become unable, admit in writing its inability or fail generally to pay its debts as they become due;

(k)one or more judgments for the payment of money in an aggregate amount in excess of $15,000,000 shall be rendered against the Borrower or any Restricted Subsidiary or any combination thereof and either the same shall remain undischarged or unsatisfied for a period of 30 consecutive days during which execution shall not be effectively stayed, or any action shall be legally taken by a judgment creditor to attach or levy upon any assets of the Borrower or any Restricted Subsidiary to enforce any such judgment;

(l)an ERISA Event shall have occurred that, in the opinion of the Majority Lenders, when taken together with all other ERISA Events that have occurred, could reasonably be expected to result in a Material Adverse Effect;

(m)the delivery by any Guarantor to the Administrative Agent of written notice that a Guarantee under Article VIII has been revoked;

(n)a Change of Control shall occur;

(o)any provision of any Loan Document, at any time after its execution and delivery and for any reason other than as expressly permitted hereunder or thereunder or satisfaction in full of all the Obligations, ceases to be in full force and effect; or any Credit Party or any other Person contests in any manner the validity or enforceability of any provision of any Loan Document; or any Credit Party denies that it has any or further liability or obligation under any provision of any Loan Document, or purports to revoke, terminate or rescind any provision of any Loan Document; or

(p)any Security Instrument after delivery thereof pursuant to Section 5.01, 6.09, 6.13, or 6.14 shall for any reason (other than pursuant to the terms thereof) cease to create a valid and perfected first priority Lien (subject to Permitted Liens) on the Collateral purported to be covered thereby;

then, and in every such event (other than an event with respect to the Borrower or any Restricted Subsidiary described in clause (h) or (i) of this Article), and at any time thereafter during the continuance of such event, the Administrative Agent may, and at the request of the Majority Lenders shall, by notice to the Borrower, take either or both of the following actions, at the same or different times: (i) terminate the Aggregate Commitment, and thereupon the Aggregate Commitment shall terminate immediately, and (ii) declare the Loans then outstanding to be due and payable in whole (or in part, in which case any principal

not so declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of the Loans so declared to be due and payable, together with accrued interest thereon and all fees and other obligations of the Borrower accrued hereunder, shall become due and payable immediately, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower; and in case of any event with respect to the Borrower described in clause (h) or (i) of this Article, the Aggregate Commitment shall automatically terminate and the principal of the Loans then outstanding, together with accrued interest thereon and all fees and other obligations of the Borrower accrued hereunder, shall automatically become due and payable, without present-ment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower. Without limiting the foregoing, upon the occurrence and during the continuance of an Event of Default, the Administrative Agent, the Issuing Bank and each Lender may protect and enforce its rights under this Agreement and the other Loan Documents by any appropriate proceedings, including proceedings for specific performance of any covenant or agreement contained in this Agreement or any other Loan Document, and the Administrative Agent, the Issuing Bank and each Lender may enforce payment of any Obligations due and payable hereunder or enforce any other legal or equitable right and remedies which it may have under this Agreement, any other Loan Document, or under applicable law or in equity.

Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto.

The bank 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 such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with any Credit Party or other Affiliate thereof as if it were not the Administrative Agent hereunder.

The Administrative Agent shall not have any duties or obligations except those expressly set forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing as directed by the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 11.02), and (c) except as expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to any Credit Party that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 11.02) or 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 written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and 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, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein, (iv) the

validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article V or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. No Person identified as a Syndication Agent, Documentation Agent, Sole Bookrunner or Lead Arranger, in each case in its respective capacity as such, shall have any responsibilities or duties, or incur any liability, under this Agreement or the other Loan Documents.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrower. Upon any such resignation, the Majority Lenders shall have the right, with the consent of the Borrower (which consent shall not be unreasonably withheld or delayed), to appoint a successor; provided that no consent of the Borrower shall be required if any Event of Default has occurred and is continuing. If no successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent which shall be a bank with an office in Chicago, Illinois or New York, New York, or an Affiliate of any such bank that is a financial institution. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 11.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub‑agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

Each Lender acknowledges and agrees that the extensions of credit made hereunder are commercial loans and letters of credit and not investments in a business enterprise or securities. Each Lender further represents that it is engaged in making, acquiring or holding commercial loans in the ordinary course of its business and has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement as a Lender, and to make, acquire or hold Loans hereunder. Each Lender shall, independently and without reliance upon the Administrative Agent or any other Lender and

based on such documents and information (which may contain material, non-public information within the meaning of the United States securities laws concerning the Borrower and its Affiliates) as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder and in deciding whether or to the extent to which it will continue as a lender or assign or otherwise transfer its rights, interests and obligations hereunder.

Each Lender and the Issuing Bank hereby authorizes the Administrative Agent to release any Collateral that it is permitted to be sold or released pursuant to the terms of the Loan Documents. Each Lender and the Issuing Bank hereby authorizes the Administrative Agent to execute and deliver to the Borrower, at the Borrower’s sole cost and expense, any and all releases of Liens, termination statements, assignments or other documents reasonably requested by the Borrower in connection with any Disposition of Collateral to the extent such Disposition is permitted by the terms of this Agreement or is otherwise authorized by the terms of the Loan Documents.

Section 11.02    Waivers; Amendments.

(a)No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder are cumulative and are

not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agree-ment or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time.

(b)Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Credit Parties and the Majority Lenders or by the Credit Parties and the Administrative Agent with the consent of the Majority Lenders; provided that no such agreement shall:

(i) increase the Borrowing Base without the written consent of each Lender;

(ii) increase the Commitment of any Lender or, except as set forth in the definition of Applicable Percentage, increase the Applicable Percentage of any Lender, in each case, without the written consent of such Lender;

(iii) increase the Maximum Facility Amount without the written consent of each Lender;

(iv) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, 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 reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any of the Aggregate Commitment, without the written consent of each Lender affected thereby (it being understood that any waiver of a mandatory prepayment of the Loans or a mandatory reduction of the Commitments shall not constitute a postponement or waiver of a scheduled payment or date of expiration);

(vi) change Section 2.18(b) or Section 2.18(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender;

(vii) except in connection with any Dispositions permitted in Section 7.04, release any Guarantor from its obligations under Article VIII or release any of the Collateral without the written consent of each Lender; or

(viii) change any of the provisions of this Section or the definition of “Super-Majority Lenders”, “Majority Lenders”, “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender;

provided further that no such agreement shall (x) amend, modify or otherwise affect the rights or duties of the Administrative Agent or the Issuing Bank hereunder without the prior written consent of the Administrative Agent or the Issuing Bank, as the case may be or (y) change any of the provisions of Section 2.20 without the prior written consent of the Administrative Agent and the Issuing Bank.

(c)Notwithstanding anything to the contrary contained in this Section 11.02, the Administrative Agent may, with the consent of the Borrower only, amend, modify or supplement

this Agreement or any of the other Loan Documents to correct any clerical errors or cure any ambiguity, omission, mistake, defect or inconsistency.

Section 11.03    Expenses; Indemnity; Damage Waiver.

(a)    The Borrower shall pay (i) all reasonable out‑of‑pocket expenses incurred by the Administrative Agent, the Lead Arranger and their Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of this Agreement and the other Loan Documents or any amendments, modifications or waivers of the provi-sions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iii) all reasonable out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, the Issuing Bank or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, or in connection with the Loans made or Letters of Credit issued hereunder, including all such out-of‑pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit.

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

(d)    To the extent permitted by applicable law, no party hereto shall assert, and each such party hereby waives, any claim against any other party hereto on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof; provided that, nothing in this clause (d) shall relieve the Borrower of any obligation it may have to indemnify an Indemnitee against special, indirect, consequential or punitive damages asserted against such Indemnitee by a third party.

(e)    All amounts due under this Section shall be payable not later than 10 days after written demand therefor.

(a)The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) no Credit Party may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by such Credit Party without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

i.Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more Persons (other than an Ineligible Institution) all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment, participations in Letters of Credit and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of:

(A)    the Borrower, provided that, the Borrower shall be deemed to have consented to an assignment unless it shall have objected thereto by written notice to the Administrative Agent within five (5) Business Days after having received notice thereof, provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a

Lender, a Federal Reserve Bank, an Approved Fund or, if an Event of Default has occurred and is continuing, any other assignee;

(B)    the Administrative Agent; and

(C)    the Issuing Bank.

ii.Assignments shall be subject to the following additional conditions:

(A)    except in the case of an assignment to a Lender, an Affiliate of a Lender, an Approved Fund or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, provided that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing;

(B)    each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of such Lender’s Commitment and such Lender’s Loans under this Agreement;

(C)    the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and

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

For the purposes of this Section 11.04(b), the term “Approved Fund” and “Ineligible Institution” have the following meanings:

“Approved Fund” means any Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages a Lender.

“Ineligible Institution” means a (a) natural person, (b) a Defaulting Lender or its Lender Parent, (c) company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural person or relative(s) thereof or (d) or the Borrower or any of its Affiliates.

iii.Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 2.15, Section 2.16, Section 2.17 and Section 11.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 11.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section except that any attempted assignment or transfer by any Lender that does not comply with clause (C) of Section 11.04(b)(ii) shall be null and void.

iv.The Administrative Agent, acting for this purpose as a non-fiduciary agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered

to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment and Applicable Percentage of, and principal amount (and stated interest) of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Credit Parties, the Administrative Agent, the Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Credit Parties, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

v.Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant to Section 2.06(d) or Section 2.06(e), Section 2.07, Section 2.18(d) or Section 11.03(c), the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

i.Any Lender may, without the consent of the Borrower, the Administrative Agent or the Issuing Bank, sell participations to one or more banks or other entities (a “Participant”), other than an Ineligible Institution, in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 11.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Section 2.15, Section 2.16 and Section 2.17 (subject to the requirements and limitations therein, including the requirements under 2.17(f) (it being understood, however, that the documentation required under Section 2.17(f) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Section 2.19 as if it were an assignee under paragraph (b) of this Section; and (B) shall not be entitled to receive any greater payment under Section 2.15 or 2.17, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower’s request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 2.19(b) with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.08 as though it were a Lender, provided that such Participant agrees to be subject to

Section 2.18(c) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Loans, Letters of Credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such Commitment, Loan, Letter of Credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

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

Section 11.05Survival. All covenants, agreements, representations and warranties made by the Credit Parties herein and in the certificates or other instru-ments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Aggregate Commitment has not expired or terminated. The provisions of Section 2.15, Section 2.16, Section 2.17 and Section 11.03 and Article X shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Aggregate Commitment or the termination of this Agreement or any provision hereof.

Section 11.06Counterparts; Integration; Effectiveness; Electronic Execution.

(a)This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. Except as provided in Section 5.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon

and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

(b)Delivery of an executed counterpart of a signature page of this Agreement by telecopy, emailed pdf. or any other electronic means that reproduces an image of the actual executed signature page shall be effective as delivery of a manually executed counterpart of this Agreement. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to any document to be signed in connection with this Agreement and the transactions contemplated hereby shall be deemed to include Electronic Signatures, deliveries 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, physical delivery thereof 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.

Section 11.07    Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

Section 11.08    Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of any Credit Party now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section and Section 8.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

Section 11.15Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under appli-cable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender. In the event that, notwithstanding Section 11.09, applicable law is the law of the State of Texas and such applicable law provides for an interest ceiling under Chapter 303 of the Texas Finance Code (the “Texas Finance Code”) as amended, for each day, the ceiling shall be the “weekly ceiling” as defined in the Texas Finance Code and shall be used in this Note and the other Loan Documents for calculating the Maximum Rate and for all other purposes.

L. 107-56 (signed into law October 26, 2001)) (the “Act”) hereby notifies each Credit Party that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies each Credit Party, which information includes the name and address of each Credit Party and other information that will allow such Lender to identify each Credit Party in accordance with the Act.

Section 11.17.    Original Credit Agreement. On the Effective Date, this Agreement shall supersede and replace in its entirety the Original Credit Agreement; provided, however, that (a) all loans, letters of credit, and other indebtedness, obligations and liabilities outstanding under the Original Credit Agreement on such date shall continue to constitute Loans, Letters of Credit and other indebtedness, obligations and liabilities under this Agreement, (b) the execution and delivery of this Agreement or any of the Loan Documents hereunder shall not constitute a novation, refinancing or any other fundamental change in the relationship among the parties and (c) the Loans, Letters of Credit, and other indebtedness, obligations and liabilities outstanding hereunder, to the extent outstanding under the Original Credit Agreement immediately prior to the date hereof, shall constitute the same loans, letters of credit, and other indebtedness, obligations and liabilities as were outstanding under the Original Credit Agreement.

FOR VALUE RECEIVED, the undersigned CLAYTON WILLIAMS ENERGY, INC., a Delaware corporation (“Borrower”) hereby unconditionally promises to pay to _____________________ (the “Lender”) or its registered assigns the principal sum equal to its Commitment as set forth in the Credit Agreement (as hereinafter defined), or, if greater or less, the aggregate unpaid principal amount of the Loans advanced by Lender to Borrower pursuant to the terms of the Credit Agreement, together with interest on the unpaid principal balance thereof as set forth in the Credit Agreement, both principal and interest payable as therein provided in lawful money of the United States of America at the offices of Administrative Agent provided in Section 11.01 of the Credit Agreement, or at such other place, as from time to time may be designated by Administrative Agent in accordance with the Credit Agreement.

The principal and all accrued interest on this Note shall be due and payable in accordance with the terms and provisions of the Credit Agreement.

This Note is executed pursuant to that certain Third Amended and Restated Credit Agreement dated as of April 23, 2014, between Borrower, certain Subsidiaries of the Borrower, as Guarantors, the Administrative Agent and Lenders (as amended, modified, supplemented or restated from time to time, the “Credit Agreement”; the terms defined therein and not otherwise defined herein being used herein as therein defined), is one of the promissory notes referred to in Section 2.09(e) therein and is secured by the Security Instruments. Reference is made to the Credit Agreement and the Loan Documents for a statement of prepayment rights and obligations of Borrower, for a statement of the terms and conditions under which the due date of this Note may be accelerated and for statements regarding other matters affecting this Note (including without limitation the obligations of the holder hereof to advance funds hereunder, principal and interest payment due dates, voluntary and mandatory prepayments, exercise of rights and remedies, payment of attorneys’ fees, court costs and other costs of collection and certain waivers by Borrower and others now or hereafter obligated for payment of any sums due hereunder). Upon the occurrence of an Event of Default, the Administrative Agent may declare forthwith to be entirely and immediately due and payable the principal balance hereof and the interest accrued hereon, and the Lender shall have all rights and remedies of the Lender under the Credit Agreement and the other Loan Documents. This Note may be prepaid in accordance with the terms and provisions of the Credit Agreement.

Regardless of any provision contained in this Note, the holder hereof shall never be entitled to receive, collect or apply, as interest on this Note, any amount in excess of the Maximum Rate, and, if the holder hereof ever receives, collects, or applies as interest, any such amount which would be excessive interest, it shall be deemed a partial prepayment of principal and treated hereunder as such; and, if the indebtedness evidenced hereby is paid in full, any remaining excess shall forthwith be paid to Borrower. In determining whether or not the interest paid or payable, under any specific contingency, exceeds the Maximum Rate, Borrower and the holder hereof shall, to the maximum 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) spread the total amount of interest throughout the entire contemplated term of the obligations evidenced by this Note and/or referred to in the Credit Agreement so that the interest rate is uniform throughout the entire term of this Note; provided that, if this Note is paid and performed in full prior to the end of the full contemplated term thereof; and if the interest received for the actual period of existence thereof exceeds the Maximum Rate, the holder hereof shall refund to Borrower the amount of such excess or credit the amount of such excess against the indebtedness evidenced hereby,

and, in such event, the holder hereof shall not be subject to any penalties provided by any laws for contracting for, charging, taking, reserving or receiving interest in excess of the Maximum Rate.

If any payment of principal or interest on this Note shall become due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day and such extension of time shall in such case be included in computing interest in connection with such payment.

If this Note is placed in the hands of an attorney for collection, or if it is collected through any legal proceeding at law or in equity or in bankruptcy, receivership or other court proceedings, Borrower agrees to pay all costs of collection, including, but not limited to, court costs and reasonable attorneys’ fees.

Borrower and each surety, endorser, guarantor and other party ever liable for payment of any sums of money payable on this Note, jointly and severally waive presentment and demand for payment, notice of intention to accelerate the maturity, protest, notice of protest and nonpayment, as to this Note and as to each and all installments hereof, and agree that their liability under this Note shall not be affected by any renewal or extension in the time of payment hereof, or in any indulgences, or by any release or change in any security for the payment of this Note, and hereby consent to any and all such renewals, extensions, indulgences, releases or changes.

This Note shall be governed by and construed in accordance with the applicable laws of the United States of America and the laws of the State of New York.

THIS NOTE, THE CREDIT AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENTS AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

EXECUTED as of the date and year first above written.
