Subject to the terms and conditions set forth herein, each Lender agrees to make a Loan to the Borrower on the Effective Date in an aggregate principal amount that will not exceed such Lender’s Commitment. The Commitments are not revolving and the Borrower may not borrow, repay and reborrow the Loans. Any portion of the Commitments not requested pursuant to Section 2.03 by the Borrower on or before 3:00 p.m. New York time on the Effective Date shall be permanently cancelled.

     Section 2.02 Loans and Borrowings. Borrowings; Several Obligations. Each Term Loan shall be made as part of a Borrowing consisting of Loans made by each Lender ratably in accordance with its respective Commitment. The failure of any Lender to make its Loan shall not relieve any other Lender of its obligations hereunder; provided that the Commitments are several and no Lender shall be responsible for any other Lender’s failure to make its Loan as required.

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

     (c) Minimum Amounts; Limitation on Number of Borrowings. At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $100,000 and not less than $500,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $100,000 and not less than $500,000; provided that an ABR Borrowing may be in an aggregate amount that is equal to the entire unused balance of the total Commitments. Borrowings of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of four (4) Eurodollar Borrowings outstanding. Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

     (d) Notes. Any Lender may request that Loans made by it be evidenced by a single promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to such Lender in substantially the form of Exhibit A, dated, in the case of (i) any Lender party hereto as of the Effective Date, as of the Effective Date or (ii) any Lender

that becomes a party hereto pursuant to an Assignment and Assumption, as of the effective date of the Assignment and Assumption, in each case, payable to such Lender in a principal amount equal to its Loans as in effect on such date, and otherwise duly completed. If the amount of any Lender’s Loans increases or decreases for any reason (whether pursuant to Section 12.04(b) or otherwise), the Borrower shall deliver or cause to be delivered on the effective date of such increase or decrease, a new Note payable to any Lender who requested a Note hereunder in a principal amount equal to its Loans after giving effect to such increase or decrease, and otherwise duly completed, and such Lender agrees to promptly thereafter return the previously issued Note held by such Lender marked canceled or otherwise similarly defaced. The date, amount, Type, interest rate and, if applicable, Interest Period of each Loan made by each Lender that receives a Note, and all payments made on account of the principal thereof, shall be recorded by such Lender on its books for its Note, and, prior to any transfer, may be endorsed by such Lender on a schedule attached to such Note or any continuation thereof or on any separate record maintained by such Lender. Failure to make any such notation or to attach a schedule shall not affect any Lender’s or the Borrower’s rights or obligations in respect of such Loans or affect the validity of such transfer by any Lender of its Note.

     Section 2.03 Requests for Borrowings. To request the Borrowing, the Borrower shall notify the Administrative Agent of such request by written Borrowing Request in substantially the form of Exhibit B and signed by the Borrower (the “Borrowing Request”): (a) in the case of a Eurodollar Borrowing, not later than 12:00 noon, New York, New York time, three Business Days before the Effective Date or (b) in the case of an ABR Borrowing, not later than 11:00 a.m., New York, New York time, on the Effective Date.

     (iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing;

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

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

     If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Promptly following receipt of a Borrowing Request in accordance with this Section 2.03, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing.

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

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

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

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

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

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

     (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

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

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

     (e) Effect of Failure to Deliver Timely Interest Election Request and Events of Default on Interest Election. If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto,

then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing: (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing (and any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective) and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

     Section 2.05 Funding of Loans. Funding by Lenders. Each Lender shall make its Loan on the Effective Date by wire transfer of immediately available funds by 1:00 p.m., New York, New York time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Administrative Agent in New York, New York and designated by the Borrower in the Borrowing Request.

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

     Section 2.07 Total Reserve Value.

     (a) Subject to interim adjustment under Section 2.07(c), Section 8.13 and Section 9.11, the initial Total Reserve Value shall be $437,175,428. The Borrower shall deliver to the Administrative Agent a Reserve Report Certificate in accordance with Section 8.12, so that the Total Reserve Value may be redetermined semi-annually on or around November 1st and May 1st of each year (each, a “Scheduled Redetermination Date” and, together with each Interim Redetermination Date, as defined below, a “Redetermination Date”) which Reserve Report Certificate shall reflect the Total Reserve Value as of the immediately preceding June 30 and December 31, respectively, commencing May 1, 2012. The Borrower shall calculate the Total Reserve Value based upon the applicable definitions of this Agreement.

     (b) Upon receipt of a Reserve Report Certificate, the Administrative Agent shall promptly review such certificate and, within five (5) Business Days, confirm to the Borrower and the Lenders that (i) the calculations used to determine the Total Reserve Value were based upon the pricing and other requirements set forth in the definition of Total Reserve Value and (ii) no mathematical or other errors or omissions have been made in such calculation. If facts under (i) or (ii) are ascertained not to exist, the Administrative Agent and the Borrower shall cooperate to promptly calculate the proper amount of the Total Reserve Value. Otherwise, upon confirmation of such amount as the Total Reserve Value, such amount will be the Total Reserve Value until next adjusted or redetermined in accordance with the terms of this Agreement.

     (c) If the Borrower or any Subsidiary changes the material terms of any commodity-price Swap Agreement, terminates any such Swap Agreement or creates any off-setting positions in respect of any hedge positions under any such Swap Agreement (whether evidenced by a floor, put or Swap Agreement), then the Total Reserve Value shall be simultaneously reduced by an amount determined by the Majority Lenders not exceeding the economic consequences of such change, termination or creation of off-setting positions.

     (d) The Borrower may elect to redetermine the Total Reserve Value, by notifying the Administrative Agent thereof, one time during any six-month period, that it elects to cause the Total Reserve Value to be redetermined between Scheduled Redeterminations (each an “Interim Redetermination”) in accordance with this Section 2.07 (each an “Interim Redetermination Date”).

The Loans, the Notes, this Agreement and the other Loan Documents, the rights and remedies of the Lenders and the Administrative Agent hereunder and thereunder and the Liens created thereby are subject to the Intercreditor Agreement. Each Lender hereunder (a) acknowledges that it has received a copy of the Intercreditor Agreement, (b) consents to the subordination of Liens provided for in the Intercreditor Agreement, (c) agrees that it will be bound by and will take no actions contrary to the provisions of the Intercreditor Agreement and (d) authorizes and instructs the Administrative Agent to enter into the Intercreditor Agreement as Second Lien Collateral Agent (as defined therein) and on behalf of such Lender. The foregoing provisions are intended as an inducement to the lenders under the First Lien Credit Agreement to permit the incurrence of Indebtedness under this Agreement and to extend credit to the Borrower and such lenders are intended third party beneficiaries of such provisions.

     (viii) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied to outstanding Borrowings as directed by the Borrower or, if no such direction is given, first, ratably to any ABR Borrowings then outstanding, and, second, to any Eurodollar Borrowings then outstanding, and if more than one Eurodollar Borrowing is then outstanding, to each such Eurodollar Borrowing in order of priority beginning with the Eurodollar Borrowing with the least number of days remaining in the Interest Period applicable thereto and ending with the Eurodollar Borrowing with the most number of days remaining in the Interest Period applicable thereto.

     (ix) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied ratably to the Loans included in the prepaid Borrowings. Prepayments pursuant to this Section 3.04(c) shall be accompanied by accrued interest to the extent required by Section 3.02.

ARTICLE IV

Payments; Pro Rata Treatment; Sharing of Set-offs.

     Section 4.01 Payments Generally; Pro Rata Treatment; Sharing of Set-offs. Payments by the Borrower. The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees, or of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 12:00 noon, New York, New York time, on the date when due, in dollars that constitute immediately available funds, without defense, deduction, recoupment, set-off or counterclaim. Fees, once paid, shall not be refundable under any circumstances absent manifest error (e.g., as a result of a clerical mistake). Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices located at Capital One Bank, Commercial Loan Servicing, 14601 Sweitzer Lane, Laurel, MD 20707, except that payments pursuant to Section 5.01, Section 5.02, Section 5.03 and Section 12.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars.

     (b) Application of Insufficient Payments. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, 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 then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties.

     (c) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans resulting in such Lender receiving payment of a greater proportion of the

aggregate amount of its Loans 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 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; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this Section 4.01(c) shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this Section 4.01(c) shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

     Section 4.02 Presumption of Payment by the Borrower. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders 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, 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, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

     Section 4.03 Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.05(a), 4.02 or 12.03(c), then the Administrative Agent may, in its discretion and notwithstanding any contrary provision hereof, (i) apply any amounts thereafter received by the Administrative Agent for the account of such Lender and for the benefit of the Administrative Agent to satisfy such Lender’s obligations 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 such Sections; in the case of each of (i) and (ii) above, in any order as determined by the Administrative Agent in its discretion.

     Section 4.04 Disposition of Proceeds. The Security Instruments contain an assignment by the Borrower to and in favor of the Administrative Agent for the benefit of the Lenders and the other Persons named therein of all of the Borrower’s interest in and to production and all proceeds attributable thereto that may be produced from or allocated to the Mortgaged Property. The Security Instruments further provide in general for the application of such proceeds to the satisfaction of the Obligations and other obligations described therein and secured thereby.

Notwithstanding the assignment contained in such Security Instruments, until the occurrence of an Event of Default, (a) the Administrative Agent and the Lenders agree that they will neither notify the purchaser or purchasers of such production nor take any other action to cause such proceeds to be remitted to the Administrative Agent or the Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrower and its Restricted Subsidiaries and (b) the Lenders hereby authorize the Administrative Agent to take such actions as may be necessary to cause such proceeds to be paid to the Borrower and/or such Restricted Subsidiaries.

ARTICLE V

Increased Costs; Break Funding Payments; Taxes; Illegality

     Section 5.01 Increased Costs. Eurodollar Changes in Law. If any Change in Law shall:

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

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

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

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

     (c) Certificates. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in Section 5.01(a) or (b) and reasonably detailed calculations therefor shall be delivered to the 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.

     (d) Effect of Failure or Delay in Requesting Compensation. Failure or delay on the part of any Lender to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrower shall

not be required to compensate a Lender pursuant to this Section 5.01 for any increased costs or reductions incurred more than 90 days prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’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 90-day period referred to above shall be extended to include the period of retroactive effect thereof.

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

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

     (b) Payment of Other Taxes by the Borrower. The Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

     (c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent and each Lender, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such

Lender, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 5.03) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate of the Administrative Agent or a Lender as to the amount of such payment or liability under this Section 5.03 shall be delivered to the Borrower and shall be conclusive absent manifest error.

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

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

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

     Section 5.04 Mitigation Obligations. Designation of Different Lending Office. If any Lender requests compensation under Section 5.01, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 5.01 or Section 5.03, as the case may be, in the future and (ii) would not subject such Lender to

any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

     (b) Replacement of Lenders. If (i) any Lender requests compensation under Section 5.01 or (ii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 12.04(b)), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that, (1) in the case of a required assignment of interest, the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (2) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, including any applicable premium then due under Section 3.04(a), 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 (3) in the case of any such assignment resulting from a claim for compensation under Section 5.01 or payments required to be made pursuant to Section 5.03, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

     Section 5.05 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its applicable lending office to honor its obligation to make or maintain Eurodollar Loans either generally or having a particular Interest Period hereunder, then (a) such Lender shall promptly notify the Borrower and the Administrative Agent thereof and such Lender’s obligation to make such Eurodollar Loans shall be suspended (the “Affected Loans”) until such time as such Lender may again make and maintain such Eurodollar Loans and (b) all Affected Loans which would otherwise be made by such Lender shall be made instead as ABR Loans (and, if such Lender so requests by notice to the Borrower and the Administrative Agent, all Affected Loans of such Lender then outstanding shall be automatically converted into ABR Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into) ABR Loans, all payments of principal which would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its ABR Loans.

ARTICLE VII

Representations and Warranties

     The Borrower represents and warrants to the Lenders that:

     Section 7.01 Organization; Powers. Each of the Borrower and the Subsidiaries is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, has all requisite power and authority, and has all material governmental licenses, authorizations, consents and approvals necessary, to own its assets and to carry on its business as now conducted, and is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required, except where failure to have such power, authority, licenses, authorizations, consents, approvals and qualifications could not reasonably be expected to have a Material Adverse Effect. As of the Effective Date, Schedule 7.01 is an accurate corporate organizational chart of Borrower and its Subsidiaries showing the ownership of all Equity Interests in such Persons.

     Section 7.02 Authority; Enforceability. The Transactions to be entered into by each Loan Party are within such Loan Party’s corporate powers and have been duly authorized by all necessary corporate and, if required, stockholder action (including, without limitation, any action required to be taken by any class of directors of such Loan Party or any other Person, whether interested or disinterested, in order to ensure the due authorization of the Transactions). Each Loan Document to which any Loan Party is a party has been duly executed and delivered by such Loan Party and constitutes a legal, valid and binding obligation of such Loan 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 7.03 Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority or any other third Person (including shareholders or any class of directors, whether interested or disinterested, of any Loan Party or any other Person), nor is any such consent, approval, registration, filing or other action necessary for the validity or enforceability of any Loan Document or the consummation of the transactions contemplated thereby, except such as have been obtained or made and are in full force and effect other than (i) the recording and filing of the Security Instruments as required by this Agreement and (ii) those third party approvals or consents which, if not made or obtained, would not cause a Default hereunder, could not reasonably be expected to have a Material Adverse Effect or do not have an adverse effect on the enforceability of the Loan Documents, (b) will not violate any applicable law or regulation or the charter, by-laws or other organizational documents of the Borrower or any Subsidiary or any order of any Governmental Authority, (c) will not violate or result in a default under any indenture, agreement or other instrument binding upon the Borrower or any Subsidiary or its Properties, or give rise to a right thereunder to require any payment to be made by the Borrower or such Subsidiary and (d) will not result in the creation or imposition of any Lien on any Property of the Borrower or any Subsidiary (other than the Liens created by the Loan Documents).

     Section 7.05 Litigation.  As of the Effective Date, except as set forth on Schedule 7.05, there are no actions, suits, investigations or proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of the Borrower, threatened in writing against or affecting the Borrower or any Subsidiary (i) as to which there is a reasonable possibility of an adverse determination that, if adversely determined, could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect or (ii) that involve any Loan Document or the Transactions.

     (b) Since the Effective Date, there has been no change in the status of the matters disclosed in Schedule 7.05 that, individually or in the aggregate, has resulted in, or materially increased the likelihood of, a Material Adverse Effect.

     Section 7.06 Environmental Matters. Except as could not reasonably be expected to have a Material Adverse Effect (or with respect to (c), (d) and (e) below, where the failure to take such actions could not be reasonably expected to have a Material Adverse Effect), to the knowledge of Borrower:

     (a) neither any Property of the Borrower or any Subsidiary nor the operations conducted thereon violate any order or requirement of any court or Governmental Authority or any Environmental Laws;

     (b) no Property of the Borrower or any Subsidiary nor the operations currently conducted thereon or by any prior owner or operator of such Property or operation, are in violation of or subject to any existing, pending or threatened action, suit, investigation, inquiry or proceeding by or before any court or Governmental Authority or to any remedial obligations under Environmental Laws;

     (c) all notices, permits, licenses, exemptions, approvals or similar authorizations, if any, required to be obtained or filed in connection with the operation or use of any and all Property of the Borrower and each Subsidiary, including, without limitation, past or present treatment, storage, disposal or release of a hazardous substance, oil and gas waste or solid waste into the environment, have been duly obtained or filed, and the Borrower and each Subsidiary are in compliance with the terms and conditions of all such notices, permits, licenses and similar authorizations;

     (d) all hazardous substances, solid waste and oil and gas waste, if any, generated at any and all Property of the Borrower or any Subsidiary have in the past been transported, treated and disposed of in accordance with Environmental Laws and so as not to pose an imminent and substantial endangerment to public health or welfare or the environment, and all such transport carriers and treatment and disposal facilities have been and are operating in compliance with Environmental Laws and so as not to pose an imminent and substantial endangerment to public health or welfare or the environment, and are not the subject of any existing, pending or threatened action, investigation or inquiry by any Governmental Authority in connection with any Environmental Laws;

     (e) the Borrower has taken all steps reasonably necessary to determine and has determined that no oil, hazardous substances, solid waste or oil and gas waste, have been disposed of or otherwise released and there has been no threatened release of any oil, hazardous substances, solid waste or oil and gas waste on or to any Property of the Borrower or any Subsidiary except in compliance with Environmental Laws and so as not to pose an imminent and substantial endangerment to public health or welfare or the environment;

     (f) to the extent applicable, all Property of the Borrower and each Subsidiary currently satisfies all design, operation, and equipment requirements imposed by the OPA, and the Borrower does not have any reason to believe that such Property, to the extent subject to the

OPA, will not be able to maintain compliance with the OPA requirements during the term of this Agreement; and

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

     Section 7.07 Compliance with the Laws and Agreements; No Defaults. Except as could not be reasonably be expected to have a Material Adverse Effect:

     (b) neither the Borrower nor any Subsidiary is in default nor has any event or circumstance occurred which, but for the expiration of any applicable grace period or the giving of notice, or both, would constitute a default or would require the Borrower or a Subsidiary to Redeem or make any offer to Redeem under any indenture, note, credit agreement or instrument pursuant to which any Material Indebtedness is outstanding or by which the Borrower or any Subsidiary or any of their Properties is bound; and

     (c) no Default has occurred and is continuing.

     Section 7.08 Investment Company Act. Neither the Borrower nor any Subsidiary is an “investment company” or a company “controlled” by an “investment company,” within the meaning of, or subject to regulation under, the Investment Company Act of 1940, as amended.

     Section 7.09 Taxes. Each of the Borrower and its Subsidiaries has timely filed or caused to be filed all Tax returns and reports required to have been filed and has paid or caused to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate proceedings and for which the Borrower or such Subsidiary, as applicable, has set aside on its books adequate reserves in accordance with GAAP or (b) to the extent that the failure to do so could not reasonably be expected to result in a Material Adverse Effect. The charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of Taxes and other governmental charges are, in the reasonable opinion of the Borrower, adequate. No Tax Lien relating to Taxes described in the first sentence of this Section 7.09 has been filed and, to the knowledge of the Borrower, no claim is being asserted with respect to any such Tax or other such governmental charge.

     Section 7.10 ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect. The present value of all accumulated benefit obligations under each Plan (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed by more than $250,000

the fair market value of the assets of such Plan, and the present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed by more than $250,000 the fair market value of the assets of all such underfunded Plans.

     Section 7.11 Disclosure; No Material Misstatements. The Borrower has disclosed to the Administrative Agent and the Lenders all agreements, instruments and corporate or other restrictions to which it or any of its Subsidiaries is subject, and all other matters known to it, that, individually or in the aggregate, could reasonably be expected to result in a Material Adverse Effect. To the knowledge of Borrower, taken as a whole, none of the other reports, financial statements, certificates or other information furnished by or on behalf of the Borrower or any Subsidiary to the Administrative Agent or any Lender or any of their Affiliates in connection with the negotiation of this Agreement or any other Loan Document or delivered hereunder or under any other Loan Document (as modified or supplemented by other information so furnished) contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that, with respect to projected financial information, prospect information, geological and geophysical data and engineering projections, the Borrower represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time. To the knowledge of Borrower there is no fact peculiar to the Borrower or any Subsidiary which could reasonably be expected to have a Material Adverse Effect or in the future is reasonably likely to have a Material Adverse Effect and which has not been set forth in this Agreement or the Loan Documents or the other documents, certificates and statements furnished to the Administrative Agent or the Lenders by or on behalf of the Borrower or any Subsidiary prior to, or on, the Effective Date in connection with the transactions contemplated hereby. There are no statements or conclusions known to the Borrower in any Reserve Report which are based upon or include misleading information or fail to take into account material information regarding the matters reported therein, it being understood that projections concerning volumes attributable to the Oil and Gas Properties and production and cost estimates contained in each Reserve Report are necessarily based upon professional opinions, estimates and projections and that the Borrower and the Subsidiaries do not warrant that such opinions, estimates and projections will ultimately prove to have been accurate.

     Section 7.12 Insurance. The Borrower has, and has caused all its Restricted Subsidiaries to have, (a) all insurance policies sufficient for the compliance by each of them with all material Governmental Requirements and all material agreements and (b) insurance coverage in at least amounts and against such risk (including, without limitation, public liability) that are usually insured against by companies similarly situated and engaged in the same or a similar business for the assets and operations of the Borrower and its Subsidiaries. The Administrative Agent and the Lenders have been named as additional insureds in respect of such liability insurance policies and the Administrative Agent has been named as loss payee with respect to Property loss insurance.

     Section 7.13 [RESERVED]

     Section 7.14 Subsidiaries. Schedule 7.14 sets forth the name of, and the ownership interest of the Borrower (as such Schedule may be updated from time to time, including pursuant to a notice delivered in accordance with Section 8.01(l))in, each Subsidiary of the Borrower. As of the Effective Date there are no Unrestricted Subsidiaries other than the Subsidiaries set forth in clause (iii) of the definition of “Unrestricted Subsidiaries” in Section 1.01.

     Section 7.15 Location of Business and Offices. The Borrower’s jurisdiction of organization is Delaware; the name of the Borrower as listed in the public records of Delaware is Magnum Hunter Resources Corporation; and the organizational identification number of the Borrower in Delaware is 2758331 (or, in each case, as set forth in a notice delivered to the Administrative Agent pursuant to Section 8.01(l) in accordance with Section 12.01). Each Subsidiary’s jurisdiction of organization, name as listed in the public records of its jurisdiction of organization and organizational identification number in its jurisdiction of organization is stated on Schedule 7.14 (as such Schedule may be updated from time to time, including pursuant to a notice delivered in accordance with Section 8.01(l)).

     Section 7.16 Properties; Titles, Etc.. Except as disclosed in Schedule 7.16, each of the Borrower and the Restricted Subsidiaries has good and defensible title to the proved Oil and Gas Properties evaluated in the most recently delivered Reserve Report (excluding, to the extent this representation and warranty is deemed to be made after the Effective Date, any such Oil and Gas Properties sold or transferred in compliance with Section 9.11) and good title to all its personal Properties, in each case, free and clear of all Liens except Liens permitted by Section 9.03. After giving full effect to the Excepted Liens, the Borrower or the Restricted Subsidiary specified as the owner owns the net interests in production attributable to the Hydrocarbon Interests as reflected in the most recently delivered Reserve Report, and the ownership of such Properties shall not in any material respect obligate the Borrower or such Restricted Subsidiary to bear the costs and expenses relating to the maintenance, development and operations of each such Property in an amount in excess of the working interest of each Property set forth in the most recently delivered Reserve Report that is not offset by a corresponding proportionate increase in the Borrower’s or such Restricted Subsidiary’s net revenue interest in such Property.

     (b) All material leases and agreements necessary for the conduct of the business of the Borrower and the Subsidiaries are valid and subsisting, in full force and effect, and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such lease or leases, which could reasonably be expected to result in a Material Adverse Effect.

     (c) The rights and Properties presently owned, leased or licensed by the Borrower and the Restricted Subsidiaries including, without limitation, all easements and rights of way, include all rights and Properties necessary to permit the Borrower and the Restricted Subsidiaries to conduct their business in all material respects in the same manner as its business has been conducted prior to the Effective Date.

     (d) All of the material Properties of the Borrower and the Restricted Subsidiaries which are reasonably necessary for the operation of their businesses are in good working condition and are maintained in accordance with prudent business standards.

     (e) The Borrower and each 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 Subsidiary does not infringe upon the rights of any other Person, except for any such infringements that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. The Borrower and its Subsidiaries either own or have valid licenses or other rights to use all databases, geological data, geophysical data, engineering data, seismic data, maps, interpretations and other technical information used in their businesses as presently conducted, subject to the limitations contained in the agreements governing the use of the same, which limitations are customary for companies engaged in the business of the exploration and production of Hydrocarbons, with such exceptions as could not reasonably be expected to have a Material Adverse Effect.

     Section 7.17 Maintenance of Properties. Except for such acts or failures to act as could not be reasonably expected to have a Material Adverse Effect, the Oil and Gas Properties (and Properties unitized therewith) have been maintained, operated and developed in a good and workmanlike manner and in conformity with all Government Requirements and in conformity with the provisions of all leases, subleases or other contracts comprising a part of the Hydrocarbon Interests and other contracts and agreements forming a part of the Oil and Gas Properties. Specifically in connection with the foregoing, except for those as could not be reasonably expected to have a Material Adverse Effect, (i) no Oil and Gas Property is subject to having allowable production reduced below the full and regular allowable (including the maximum permissible tolerance) because of any overproduction (whether or not the same was permissible at the time) and (ii) to the knowledge of Borrower, none of the wells comprising a part of the Oil and Gas Properties (or Properties unitized therewith) is deviated from the vertical more than the maximum permitted by Government Requirements, and such wells are, in fact, bottomed under and are producing from, and the well bores are wholly within, the Oil and Gas Properties (or in the case of wells located on Properties unitized therewith, such unitized Properties). All pipelines, wells, gas processing plants, platforms and other material improvements, fixtures and equipment owned in whole or in part by the Borrower or any of its Subsidiaries that are necessary to conduct normal operations are being maintained in a state adequate to conduct normal operations, and with respect to such of the foregoing that are operated by the Borrower or any of its Subsidiaries, in a manner consistent with the Borrower’s or its Subsidiaries’ past practices (other than those the failure of which to maintain in accordance with this Section 7.17 could not reasonably be expect to have a Material Adverse Effect).

     Section 7.18 Gas Imbalances, Prepayments. As of the Effective Date, except as set forth on Schedule 7.18 or on the most recent Reserve Report Certificate delivered pursuant to Section 8.12(c), on a net basis there are no gas imbalances, take or pay or other prepayments which would require the Borrower or any of the Restricted Subsidiaries to deliver Hydrocarbons produced from the Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor exceeding 500 mmcf equivalent in the aggregate.

     Section 7.19 Marketing of Production. Except for contracts listed and in effect on the Effective Date on Schedule 7.19, and thereafter either disclosed in writing to the Administrative Agent or included in the most recently delivered Reserve Report (with respect to all of which contracts the Borrower represents that it or its Subsidiaries are receiving a price for all production sold thereunder which is computed substantially in accordance with the terms of the

relevant contract and are not having deliveries curtailed substantially below the subject Property’s delivery capacity), no material agreements exist which are not cancelable on 60 days notice or less without penalty or detriment for the sale of production from the Borrower’s or the Restricted Subsidiaries’ Hydrocarbons (including, without limitation, calls on or other rights to purchase, production, whether or not the same are currently being exercised) that (a) pertain to the sale of production at a fixed price and (b) have a maturity or expiry date of longer than six (6) months from the Effective Date.

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

     Section 7.21 Use of Loans. The proceeds of the Loans shall be used (i) to provide working capital for drilling, exploration and production, midstream trading and marketing operations, (ii) for general corporate purposes of the Borrower and its Subsidiaries, including the acquisition of exploration and production and midstream properties, (iii) to pay amounts outstanding under the First Lien Credit Facility, or (iv) to pay fees and expenses in connection with the First Lien Credit Facility and this Agreement. The Borrower and its Subsidiaries are not engaged principally, or as one of its or their important activities, in the business of extending credit for the purpose, whether immediate, incidental or ultimate, of buying or carrying margin stock (within the meaning of Regulation T, U or X of the Board). No part of the proceeds of the Loans will be used for any purpose which violates the provisions of Regulations T, U or X of the Board.

     Section 7.22 Solvency. Before and after giving effect to the Transactions, (a) the aggregate assets, at a fair valuation, of the Borrower and its Restricted Subsidiaries, taken as a whole, will exceed the aggregate Debt of the Borrower on a consolidated basis, as the Debt becomes absolute and matures, (b) none of the Borrower nor any Restricted Subsidiary will have incurred or intended to incur, and will not believe that it will incur, Debt beyond its ability to pay such Debt as such Debt becomes absolute and matures and (c) none of the Borrower nor any Restricted Subsidiary will have (nor will have any reason to believe that it will have thereafter) unreasonably small capital for the conduct of its business.

The Reserve Report as of January 1st of each year and the Reserve Report delivered in connection with the first redetermination of the Total Reserves after the Effective Date shall be prepared by Borrower or an Approved Petroleum Engineer and audited by one or more Approved Petroleum Engineers, and the July 1st Reserve Report of each year shall be prepared by or under the supervision of the chief engineer of the Borrower. In each case, the chief engineer of Borrower shall certify such Reserve Report is based on information that was prepared in good faith based upon assumptions believed to be reasonable at the time and to have been prepared in accordance with the procedures used in the immediately preceding Reserve Report.

     (b) In the event of an Interim Redetermination, the Borrower shall furnish to the Administrative Agent and the Lenders a Reserve Report prepared by or under the supervision of the chief engineer of the Borrower who shall certify such Reserve Report to be based on information that was prepared in good faith based upon assumptions believed to be reasonable at the time and to have been prepared in accordance with the procedures used in the immediately preceding Reserve Report. For any Interim Redetermination requested by the Borrower pursuant to Section 2.07(d), the Borrower shall provide such Reserve Report with an “as of” date as required by the Administrative Agent as soon as possible, but in any event no later than forty-five (45) days following the receipt of such request.

     (c) With the delivery of each Reserve Report, the Borrower shall provide to the Administrative Agent and the Lenders a certificate (each a “Reserve Report Certificate”) from a Responsible Officer certifying that to his knowledge, after reasonable investigation, in all material respects: (i) the information contained in the Reserve Report and any other information delivered in connection therewith is based on information that was prepared in good faith based upon assumptions believed to be reasonable at the time, (ii) the Borrower or its Subsidiaries owns good and defensible title to the proved Oil and Gas Properties evaluated in such Reserve Report and such Properties are free of all Liens except for Liens permitted by Section 9.03, (iii) except as set forth on an exhibit to the certificate, on a net basis there are no gas imbalances, take or pay or other prepayments in excess of the volume specified in Section 7.18 with respect to its Oil and Gas Properties evaluated in such Reserve Report which would require the Borrower or any Subsidiary to deliver Hydrocarbons either generally or produced from such Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor, (iv)

none of the Borrower’s and its Subsidiaries’ proved Oil and Gas Properties have been sold since the date of the last determination of the Total Reserve Value except as set forth on an exhibit to the certificate, which certificate shall list all of its proved Oil and Gas Properties sold and in such detail as reasonably required by the Administrative Agent, (v) attached to the certificate is a list of all marketing agreements entered into subsequent to the later of the Effective Date or the most recently delivered Reserve Report which the Borrower could reasonably be expected to have been obligated to list on Schedule 7.19 had such agreement been in effect on the Effective Date and (vi) attached thereto is a schedule of the proved Oil and Gas Properties evaluated by such Reserve Report that are Mortgaged Properties and demonstrating the percentage of the Total Reserve Value that the value of such Mortgaged Properties represent.

     Section 8.13 Title Information. On or before the delivery to the Administrative Agent and the Lenders of each Reserve Report required by Section 8.12(a), the Borrower will deliver title information in form and substance acceptable to the Administrative Agent covering enough of the proved Oil and Gas Properties evaluated by such Reserve Report that were not included in the immediately preceding Reserve Report, so that the Administrative Agent shall have received together with title information previously delivered, satisfactory title information on at least 80% of the total value of the proved Oil and Gas Properties evaluated by such Reserve Report.

     (b) If the Borrower has provided title information for additional Properties under Section 8.13(a), the Borrower shall, within 60 days of notice from the Administrative Agent that title defects or exceptions exist with respect to such additional Properties, either (i) cure any such title defects or exceptions (including defects or exceptions as to priority) which are not permitted by Section 9.03 raised by such information, (ii) substitute acceptable Mortgaged Properties with no title defects or exceptions except for Excepted Liens (other than Excepted Liens described in clauses (e), (g) and (h) of such definition) having an equivalent value or (iii) deliver title information in form and substance acceptable to the Administrative Agent so that they shall have received, together with title information previously delivered, satisfactory title information on at least 80% of the value of the Oil and Gas Properties evaluated by such Reserve Report.

     (c) If the Borrower is unable to cure any title defect requested to be cured within the 60-day period or the Borrower does not comply with the requirement to provide acceptable title information covering 80% of the value of the Oil and Gas Properties evaluated in the most recent Reserve Report, such default shall not be a Default, but instead the Administrative Agent and/or the Required Lenders shall have the right to exercise the following remedy in their sole discretion from time to time, and any failure to so exercise this remedy at any time shall not be a waiver as to future exercise of the remedy by the Administrative Agent or the Lenders. To the extent that the Administrative Agent or the Required Lenders are not satisfied with title to any Mortgaged Property after the 60-day period has elapsed, such unacceptable Mortgaged Property shall not count towards the 80% requirement and the Administrative Agent may send a notice to the Borrower and the Lenders that the Total Reserve Value then in effect shall be reduced by an amount as determined by the Required Lenders to cause the Borrower to be in compliance with the requirement to provide acceptable title information on 80% of the total value of the Oil and Gas Properties. This new Total Reserve Value shall become effective immediately after receipt of such notice.

     Section 8.14 Additional Collateral. In connection with each calculation of the Total Reserve Value, the Borrower shall review the Reserve Report and the list of current Mortgaged Properties (as described in Section 8.12(c)) to ascertain whether the Mortgaged Properties represent at least 80% of the total value of the proved Oil and Gas Properties owned by Borrower and the Restricted Subsidiaries and evaluated in the most recently completed Reserve Report after giving effect to exploration and production activities, acquisitions, dispositions and production. In the event that the Mortgaged Properties do not represent at least 80% of such total value evaluated in the most recently completed Reserve Report, then the Borrower shall, and shall cause its Restricted Subsidiaries to, grant to the Administrative Agent as security for the Obligations a second-priority Lien interest (subject only to Excepted Liens of the type described in clauses (a) to (d) and (f) of the definition thereof, but subject to the provisos at the end of such definition) on additional Oil and Gas Properties not already subject to a Lien of the Security Instruments such that after giving effect thereto, the Mortgaged Properties will represent at least 80% of the total value of the Oil and Gas Properties evaluated in the most recently delivered Reserve Report. All such Liens will be created and perfected by and in accordance with the provisions of mortgages, deeds of trust, security agreements and financing statements or other Security Instruments, all in form and substance satisfactory to the Administrative Agent and in sufficient executed (and acknowledged where necessary or appropriate) counterparts for recording purposes.

     (b) The Borrower agrees that it will not, and will not permit any Subsidiary to, grant a Lien on any Property to secure the First Lien Credit Agreement without first granting to the Administrative Agent to secure the Indebtedness a perfected Lien (subject only to Liens securing the First Lien Credit Agreement) on this same Property pursuant to Security Instruments in form and substance satisfactory to the Administrative Agent.

     Section 8.15 ERISA Compliance. In addition to and without limiting the generality of Section 8.09, the Borrower shall and shall cause each of its Subsidiaries to (a) comply in all material respects with all applicable provisions of ERISA and the regulations and published interpretations thereunder with respect to all employee benefit plans (as defined in ERISA), (b) not take any action or fail to take action the result of which could be (i) a liability to the PBGC (other than liability for PBGC premiums) or (ii) a past due liability to any Multiemployer Plan, (c) not participate in any prohibited transaction that could result in any material civil penalty under ERISA or any tax under the Code, (d) operate each employee benefit plan in such a manner that will not incur any material tax liability under Section 4980B of the Code or any liability to any qualified beneficiary as defined in Section 4980B of the Code except to the extent such failure to comply could not reasonably be expected to have Material Adverse Effect and (e) furnish to the Administrative Agent upon the Administrative Agent’s request such additional information about any employee benefit plan as may be reasonably requested by the Administrative Agent.

     Section 8.16 New Subsidiary Requirements. Concurrently with the acquisition or formation of any Subsidiary which is to be a Restricted Subsidiary and in any event prior to or concurrently with the Borrower’s advancing or contributing any amounts to or into such Restricted Subsidiary (other than de minimis organizational costs such as filing fees), the Borrower shall cause to be delivered to the Administrative Agent (i) the Guaranty and a Security Agreement executed by such Restricted Subsidiary, (ii) a Security Agreement covering the

Equity Interests of such Restricted Subsidiary, (iii) stock certificates or other instruments representing all the Equity Interests of such Restricted Subsidiary and stock powers and instruments of transfer, endorsed in blank, with respect to such stock certificates or other instruments, or, if any Equity Interests pledged pursuant to such Security Agreement are uncertificated securities, confirmation and evidence satisfactory to the Administrative Agent that the security interest in such uncertificated securities has been transferred to and perfected by the Administrative Agent in accordance with the UCC, (iv) all documents and instruments, including UCC Financing Statements (Form UCC-1), required by law or reasonably requested by the Administrative Agent to be filed, registered or recorded to create or perfect the Liens intended to be created under each Security Agreement, (v) UCC searches, all dated reasonably close to the date of the Security Agreements and in form and substance satisfactory to the Administrative Agent, and evidence reasonably satisfactory to the Administrative Agent that any Liens indicated in such UCC searches are Excepted Liens or have been released, (vi) the corporate resolutions or similar approval documents of such Restricted Subsidiary approving the execution and delivery of the Guaranty and the Security Agreement by such Restricted Subsidiary, (vii) the corporate resolutions or similar approval documents of the Borrower or other Loan Party approving the execution and delivery of the Security Agreement by the Borrower or other Loan Party, and (viii) the legal opinion reasonably acceptable to the Administrative Agent, opining favorably on the execution, delivery and enforceability of the Guaranty and the Security Agreements and otherwise being in form and substance reasonably satisfactory to the Administrative Agent and its counsel.

Upon any such resignation or removal, the Required Lenders shall have the right, in consultation with and upon the approval of the Borrower (so long as no Event of Default has occurred and is continuing), which approval shall not be unreasonably withheld, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation or removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as 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 XI and Section 12.03 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.

     Section 11.07 Administrative Agent as Lender. Each 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 the Borrower or any Subsidiary or other Affiliate thereof as if it were not the Administrative Agent hereunder.

     Section 11.08 No Reliance Each Lender acknowledges that it 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 and each other Loan Document to which it is a party. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document, any related agreement or any document furnished hereunder or thereunder. The Administrative Agent shall not be required to keep itself informed as to the performance or observance by the Borrower or

any of its Subsidiaries of this Agreement, the Loan Documents or any other document referred to or provided for herein or to inspect the Properties or books of the Borrower or its Subsidiaries. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder, neither the Administrative Agent nor the Arranger shall have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of the Borrower (or any of its Affiliates) which may come into the possession of the Administrative Agent or any of its Affiliates. In this regard, each Lender acknowledges that Simpson Thacher & Bartlett LLP is acting in this transaction as special counsel to the Administrative Agent and Arrangers only, except to the extent otherwise expressly stated in any legal opinion or any Loan Document. Each other party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein.

     (b) The Lenders acknowledge that BMO Capital Markets Corp., in its capacity as an Arranger hereunder, and Bank of Montreal, as First Lien Administrative Agent and as Syndication Agent, are acting solely in administrative capacities with respect to the structuring and syndication of this Agreement and have no duties, responsibilities or liabilities under this Agreement and the other Loan Documents other than their administrative duties, responsibilities and liabilities specifically as set forth in the Loan Documents and, in the case of Bank of Montreal, its capacity as a Lender hereunder. In structuring, arranging or syndicating this Agreement, each Lender acknowledges that BMO Capital Markets Corp. and Bank of Montreal may be an agent or lender under these Notes, the First Lien Credit Agreement, other loans or other securities and waives any existing or future conflicts of interest associated with the their role in such other debt instruments. If in its administration of this facility or any other debt instrument, either BMO Capital Markets Corp. or Bank of Montreal determines (or is given written notice by any Lender that a conflict exists), then it shall eliminate such conflict within ninety (90) days or resign and shall have no liability for action taken or not taken while such conflict existed.

     Section 11.09 Authority to Release Collateral and Liens. Each Lender hereby authorizes the Administrative Agent to release any collateral that is permitted to be sold or released pursuant to the terms of the Loan Documents. Each Lender hereby authorizes the Administrative Agent to execute and deliver to the Borrower, at the Borrower’s sole cost and expense, any and all releases of Liens, termination statements, assignments or other documents reasonably requested by the Borrower in connection with any sale or other disposition of Property to the extent such sale or other disposition is permitted by the terms of Section 9.11 or is otherwise authorized by the terms of the Loan Documents.

     Section 11.10 The Arrangers, the Syndication Agent and the Documentation Agent. None of the Arrangers, the Syndication Agent or the Documentation Agent shall have any duties, responsibilities or liabilities under this Agreement and the other Loan Documents other than, in the case of any Persons that are also Lenders, their duties, responsibilities and liabilities in their capacities as Lenders hereunder.

     Section 11.11 Filing of Proofs of Claim. In case of any Default or Event of Default under Section 10.01(g), Section 10.01(h) or Section 10.01(i), the Administrative Agent (regardless of whether the principal of any Loan shall then be due and payable and regardless of

whether the Administrative Agent has made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise:

     (a) to (i) file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other Obligations that is owing and unpaid and (ii) file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the Administrative Agent under Section 3.03 and Section 12.03) allowed in such judicial proceeding; and

     (b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same.

Each Lender hereby authorizes any custodian, receiver, assignee, trustee, conservator, sequestrator or other similar official in any such judicial proceeding: (i) to make such payments to the Administrative Agent; and (ii) if the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Section 3.03 and Section 12.03. Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or to authorize the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding. Each Lender retains its right to file and prove a claim separately.

     Section 11.12 Acknowledgement Regarding Securities Laws. In making its decision to become a Lender hereunder, each Lender acknowledges that the Loans made hereunder to the Borrower and any Notes (or other promissory note) made by the Borrower pursuant hereto are not securities and that this Agreement, the Loans, the Notes and the syndication and/or sale or assignment of Loans hereunder, are not subject to any federal or state securities laws.

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

     (b) Neither this Agreement nor any provision hereof nor any Security Instrument nor any provision thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Lender’s Loan or reduce the rate of interest thereon, without the written consent of such Lender, (iii) postpone the scheduled date of payment of the principal amount of any Loan, or any interest thereon, or any fees payable hereunder, or any other Obligations hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Maturity Date without the written

consent of each Lender affected thereby (it being understood that a waiver of a mandatory prepayment shall not constitute a waiver, excuse or postponement of a scheduled date or payment), (iv) change Section 4.01(b) or Section 4.01(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) waive or amend Section 8.14, without the written consent of each Lender, (vi) release any of the collateral (other than as provided in Section 11.09), or (vii) change any of the provisions of this Section 12.02(b) or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or under any other Loan Documents or make any determination or grant any consent hereunder or any other Loan Documents, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent hereunder or under any other Loan Document without the prior written consent of the Administrative Agent. Notwithstanding the foregoing, any supplement to Schedule 7.14 (Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental schedule clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders.

     Section 12.03 Expenses, Indemnity; Damage Waiver.  The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and their Affiliates, including, without limitation, the reasonable fees, charges and disbursements of counsel and other outside consultants for the Administrative Agent, the reasonable travel, photocopy, mailing, courier, telephone and other similar expenses, and the cost of environmental audits and surveys and appraisals, in connection with the syndication of the credit facilities provided for herein, the preparation, negotiation, execution, delivery and administration (both before and after the execution hereof and including advice of counsel to the Administrative Agent as to the rights and duties of the Administrative Agent and the Lenders with respect thereto) of this Agreement and the other Loan Documents and any amendments, modifications or waivers of or consents related to the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all costs, expenses, Taxes, assessments and other charges incurred by the Administrative Agent or any Lender in connection with any filing, registration, recording or perfection of any security interest contemplated by this Agreement or any Security Instrument or any other document referred to therein, and (iii) all out-of-pocket expenses incurred by the Administrative Agent or any Lender, including the reasonable fees, charges and disbursements of any counsel for the Administrative Agent or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement or any other Loan Document, including its rights under this Section 12.03, or in connection with the Loans made hereunder, including, without limitation, all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans.

     (b) The Borrower shall indemnify the Arranger, the Administrative Agent and each Lender, and each Related Party of any of the foregoing persons (each such person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the reasonable fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement or any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto or the parties to any other Loan Document of their

respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby or by any other Loan Document, (ii) the failure of the Borrower or any Subsidiary to comply with the terms of any Loan Document, including this Agreement, or with any Governmental Requirement, (iii) any inaccuracy of any representation or any breach of any warranty or covenant of the Borrower set forth in any of the Loan Documents or any instruments, documents or certifications delivered in connection therewith, (iv) any loan or the use of the proceeds therefrom, (v) the operations of the business of the Borrower and its Subsidiaries by the Borrower and its Subsidiaries, (vi) any assertion that the Lenders were not entitled to receive the proceeds received pursuant to the Security Instruments, (vii) any Environmental Law applicable to the Borrower or any Subsidiary or any of their properties, including without limitation, the presence, generation, storage, release, threatened release, use, transport, disposal, arrangement of disposal or treatment of oil, oil and gas wastes, solid wastes or hazardous substances on any of their properties, (viii) the breach or non-compliance by the Borrower or any Subsidiary with any Environmental Law applicable to the Borrower or any Subsidiary, (ix) the past ownership by the Borrower or any Subsidiary of any of their properties or past activity on any of their properties which, though lawful and fully permissible at the time, could result in present liability, (x) the presence, use, release, storage, treatment, disposal, generation, threatened release, transport, arrangement for transport or arrangement for disposal of oil, oil and gas wastes, solid wastes or hazardous substances on or at any of the properties owned or operated by the Borrower or any Subsidiary or any actual or alleged presence or release of hazardous materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, (xi) any environmental liability related in any way to the Borrower or any of its Subsidiaries, (xii) any other environmental, health or safety condition in connection with the Loan Documents, or (xiii) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any indemnitee is a party thereto, and such Indemnity shall extend to each Indemnitee notwithstanding the sole or concurrent negligence of every kind or character whatsoever, whether active or passive, whether an affirmative act or an omission, including without limitation, all types of negligent conduct identified in the restatement (second) of torts of one or more of the Indemnitees or by reason of strict liability imposed without fault on any one or more of the Indemnitees; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (a) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee, (b) relate to agreements, or obligations to which Borrower and its Subsidiaries are not parties, (c) relate to claims between or among any of the Lenders, the Administrative Agent, the Arranger or any of their shareholders, partners or members, or (d) relate to laws, rules or regulations affecting the Lenders, the Administrative Agent or the Arranger and not the Borrower or its Subsidiaries, or (e) in respect of any property for any occurrence arising from the acts or omissions of the Administrative Agent or any Lender during the period after which such Person, its successors or assigns shall have obtained possession of such property (whether by foreclosure or deed in lieu of foreclosure, as mortgagee -in-possession or otherwise).

     (c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent under Section 12.03(a) or (b), each Lender severally agrees to pay to the Administrative Agent such Lender’s pro rata percentage of the total Loans (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such

unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such.

     (d) To the extent permitted by applicable law, the Borrower and the Indemnified Parties shall not assert, and hereby waive, any claim against each other, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the Transactions, or the use of the proceeds thereof.

     (e) All amounts due under this Section 12.03 shall be payable promptly after written demand therefor.

     Section 12.04 Successors and Assigns.  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, except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section 12.04. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants (to the extent provided in Section 12.04(c)) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

     (b) (i) Subject to the conditions set forth in Section 12.04(b)(ii), any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld or delayed) of: (1) the Borrower, provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, any other assignee, provided further that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five Business Days after having received written notice thereof; and (2) the Administrative Agent.

     (ii) Assignments shall be subject to the following additional conditions: (1) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Loans, the amount of the 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 $2,500,000, and the Loans of any assigning Lender remaining a party hereto after giving effect to the assignment shall be at least $2,500,000, unless, in each case, each of the Borrower, the Administrative Agent otherwise consents, provided that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing; (2) each partial assignment shall be

made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement; (3) 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; (4) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire and shall deliver notice of the Assignment and Assumption to the Borrower; and (5) in the case of an assignment to a CLO, the assigning Lender shall retain the sole right to approve any amendment, modification or waiver of any provision of this Agreement, provided that the Assignment and Assumption between such Lender and such CLO may provide that such Lender will not, without the consent of such CLO, agree to any amendment, modification or waiver described in the first proviso to Section 12.02 that affects such CLO.

     (iii) Subject to Section 12.04(b)(iv) and the acceptance and recording thereof, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 5.01, Section 5.02, Section 5.03 and Section 12.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 12.04(c).

     (iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice. In connection with any changes to the Register, if necessary, the Administrative Agent will reflect the revisions on Annex I and forward a copy of such revised Annex I to the Borrower and each Lender.

     (v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in Section 12.04(b) and any written consent to such assignment required by Section 12.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the

Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 12.04(b).

     (c) (i) Any Lender may, without the consent of the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of the Loans owing to it); provided that (1) such Lender’s obligations under this Agreement shall remain unchanged, (2) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (3) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the proviso to Section 12.02 that affects such Participant. In addition such agreement must provide that the Participant be bound by the provisions of Section 12.03. Subject to Section 12.04(c)(ii), the Borrower agrees that each Participant shall be entitled to the benefits of Section 5.01, Section 5.02 and Section 5.03 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.04(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.08 as though it were a Lender, provided such Participant agrees to be subject to Section 4.01(c) as though it were a Lender.

     (ii) A Participant shall not be entitled to receive any greater payment under Section 5.01 or Section 5.03 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 5.03 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 5.03(e) as though it were a Lender.

     (d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section 12.04(d) shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

     (e) Notwithstanding any other provisions of this Section 12.04, no transfer or assignment of the interests or obligations of any Lender or any grant of participations therein shall be permitted if such transfer, assignment or grant would require the Borrower to file a registration statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any state.

     Section 12.05 Survival; Revival; Reinstatement.  All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent 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. The provisions of Section 5.01, Section 5.02, Section 5.03 and Section 12.03 and ARTICLE XI shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, or the termination of this Agreement, any other Loan Document or any provision hereof or thereof.

     (b) To the extent that any payments on the Obligations or proceeds of any collateral are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law, common law or equitable cause, then to such extent, the Obligations so satisfied shall be revived and continue as if such payment or proceeds had not been received and the Administrative Agent’s, and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and each Loan Document shall continue in full force and effect. In such event, each Loan Document shall be automatically reinstated and the Borrower shall take such action as may be reasonably requested by the Administrative Agent or the Lenders to effect such reinstatement.

     Section 12.06 Counterparts; Integration; Effectiveness.  This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract.

     (b) This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Arranger and the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof and thereof. This Agreement and the other Loan Documents represent the final agreement among the parties hereto and thereto and may not be contradicted by evidence of prior, contemporaneous or subsequent oral agreements of the parties. There are no unwritten oral agreements between the parties.

     (c) Except as provided in Secttion 6.01(a), this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

     Section 12.07 Severability. Any provision of this Agreement or any other Loan Document held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof or thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

     Section 12.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations (of whatsoever kind, including, without limitation, Swap Agreements with the Borrower or any Restricted Subsidiary) at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower or any Restricted Subsidiary against any of and all the obligations of the Borrower or any Restricted Subsidiary owed to such Lender now or hereafter existing under this Agreement or any other Loan Document, irrespective of whether or not such Lender shall have made any demand under this Agreement or any other Loan Document and although such obligations may be unmatured. The rights of each Lender under this Section 12.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender or its Affiliates may have.

     Section 12.09 Governing Law; Jurisdiction; Consent to Service of Process.  This Agreement and the Loan Documents shall be governed by, and construed in accordance with, the laws of the State of New York without regard to any choice-of-law provisions that would require the application of the law of another jurisdiction; provided, to the extent any of the Security Instruments recite that they are governed by the law of another jurisdiction, or any action or event taken thereunder (such as foreclosure of the Mortgaged Property) requires application of or compliance with the law of another jurisdiction, such provisions and concepts shall apply.

     (b) Any legal action or proceeding with respect to the Loan Documents shall be brought in the courts of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and, by execution and delivery of this Agreement, each party hereby accepts for itself and (to the extent permitted by law) in respect of its property, generally and unconditionally, the jurisdiction of the aforesaid courts. Each party hereby irrevocably waives any objection, including, without limitation, any objection to the laying of venue or based on the grounds of forum non conveniens, which it may now or hereafter have to the bringing of any such action or proceeding in such respective jurisdictions. This submission to jurisdiction is non-exclusive and does not preclude a party from obtaining jurisdiction over another party in any court otherwise having jurisdiction.

     (c) Each party irrevocably consents to the service of process of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid, to it at the address specified in Section 12.01 or such other address as is specified pursuant to Section 12.01 (or its assignment and assumption), such service to become effective thirty (30) days after such mailing. Nothing herein shall affect the right of a party or any holder of a note to serve process in any other manner permitted by law

or to commence legal proceedings or otherwise proceed against another party in any other jurisdiction.

     (d) Each party hereby (i) irrevocably and unconditionally waives, to the fullest extent permitted by law, trial by jury in any legal action or proceeding relating to this Agreement or any other Loan Document and for any counterclaim therein; (ii) irrevocably waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any such litigation any special, exemplary, punitive or consequential damages, or damages other than, or in addition to, actual damages; (iii) certifies that no party hereto nor any representative or agent of counsel for any party hereto has represented, expressly or otherwise, or implied that such party would not, in the event of litigation, seek to enforce the foregoing waivers, and (iv) acknowledges that it has been induced to enter into this Agreement, the Loan Documents and the transactions contemplated hereby and thereby by, among other things, the mutual waivers and certifications contained in this Section 12.09.

     Section 12.10 Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

     Section 12.11 Confidentiality. Each of the Administrative Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority or self-regulatory body; provided Borrower has been given reasonable advance notice thereof and been afforded an opportunity to limit or protest the disclosure, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process; provided Borrower has been given reasonable advance notice thereof and been afforded an opportunity to limit or protest the disclosure, (d) to any other party to this Agreement or any other Loan Document, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section 12.11, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any Swap Agreement relating to the Borrower and its obligations, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section 12.11 or (ii) becomes available to the Administrative Agent or any Lender on a nonconfidential basis from a source other than the Borrower. For the purposes of this Section 12.11, “Information” means all information received from the Borrower or any Subsidiary relating to the Borrower or any Subsidiary and their businesses, other than any such information that is available to the Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by the Borrower or a Subsidiary. Any Person required to maintain the confidentiality of Information as provided in this Section 12.11 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to

maintain the confidentiality of such Information as such Person would accord to its own confidential information.

     Section 12.12 Exculpation Provisions. Each of the parties hereto specifically agrees that it has a duty to read this Agreement and the other Loan Documents and agrees that it is charged with notice and knowledge of the terms of this Agreement and the other Loan Documents; that it has in fact read this Agreement and is fully informed and has full notice and knowledge of the terms and conditions of this Agreement; that it has been represented by independent legal counsel of its choice throughout the negotiations preceding its execution of this Agreement and the other Loan Documents; and has received the advice of its attorney in entering into this Agreement and the other Loan Documents; and that it recognizes that certain of the terms of this Agreement and the other Loan Documents may result, subject to the terms hereof and thereof and applicable law, in one party assuming the liability inherent in some aspects of the transaction and relieving the other party of its responsibility for such liability. Each party hereto agrees and covenants that it will not contest the validity or enforceability of any exculpatory provision of this Agreement and the other loan documents on the basis that the party had no notice or knowledge of such provision or that the provision is not “conspicuous.”

     Section 12.13 No Third Party Beneficiaries. This Agreement, the other Loan Documents, and the agreement of the Lenders to make Loans hereunder are solely for the benefit of the Borrower, and no other Person (including, without limitation, any Subsidiary of the Borrower, any obligor, contractor, subcontractor, supplier or materialmen) shall have any rights, claims, remedies or privileges hereunder or under any other Loan Document against the Administrative Agent or any Lender for any reason whatsoever. There are no third party beneficiaries.

     Section 12.14 USA Patriot Act Notice. Each Lender hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Patriot Act.

     Section 12.15 Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan or reimbursement obligation, together with all fees, charges and other amounts that are treated as interest on such Loan or reimbursement obligation under applicable law (collectively the “Charges”), shall exceed the Highest Lawful Rate that may be contracted for, charged, taken, received or reserved by the Lender holding such Loan or reimbursement obligation in accordance with applicable law, the rate of interest payable in respect of such Loan or reimbursement obligation hereunder, together with all Charges payable in respect thereof, shall be limited to the Highest Lawful Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan or reimbursement obligation 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, reimbursement obligations or periods shall be increased (but not above the Highest Lawful Rate therefor) until such cumulated amount shall have been received by such Lender and in the event that, notwithstanding the foregoing, under any circumstances the aggregate amounts taken,

reserved, charged, received or paid on the Loans include amounts which by applicable law are deemed interest which would exceed the Highest Lawful Rate, then such excess shall be deemed to be a mistake and each Lender receiving same shall credit the same on the principal of its Loans (or if such Loans shall have been paid in full, refund said excess to the Borrower). In the event that the maturity of the Obligations are accelerated by reason of any election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest may never include more than the Highest Lawful Rate, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited on the Obligations (or, if the applicable Loans shall have been paid in full, refunded to the Borrower of such interest). The provisions of this Section shall control over all other provisions of this Agreement or the other Loan Documents which may be in apparent conflict herewith.
