the option of each Lender, a modification of the existing Note payable to the order of such Lender) in a principal amount equal to its Maximum Credit Amount after giving effect to such increase or decrease, and otherwise duly completed. The date, amount, Type, interest rate and, if applicable, Interest Period of each Loan made by each Lender, and all payments made on account of the principal thereof, shall be recorded by the Administrative Agent and such Lender, as applicable, on its books, and, prior to any transfer, may be endorsed by such Lender on a schedule attached to any Note or any continuation thereof or on any separate record maintained by the Administrative Agent and such Lender.

The accounts or records maintained by the Administrative Agent and each Lender shall be conclusive absent manifest error of the amount of the credit extensions made by the Lenders to the Borrower and the interest and payments thereon.

To request a Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 11:00 a.m., Houston, Texas time, three Business Days before the date of the proposed Borrowing or (b) in the case of an ABR Borrowing, not later than 11:00 a.m., Houston, Texas time, on the date of the proposed Borrowing; provided that no such notice shall be required for any deemed request of an ABR Borrowing to finance the reimbursement of an LC Disbursement as provided in Section 2.08(e). Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or facsimile to the Administrative Agent of a written Borrowing Request in substantially the form of Exhibit B and signed by the Borrower. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02:

(i) the aggregate amount of the requested Borrowing;

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

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

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

(v) the amount of the (A) then effective Aggregate Commitments, (B) then effective Borrowing Base, (C) the current total Revolving Credit Exposures (without regard to the requested Borrowing) and (D) the pro forma total Revolving Credit Exposures (giving effect to the requested Borrowing); and

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

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month's

duration. Each Borrowing Request shall constitute a representation that the amount of the requested Borrowing shall not cause the total Revolving Credit Exposures for all Lenders to exceed the lesser of (x) the Aggregate Commitments and (y) the then effective Borrowing Base.

Promptly following receipt of a Borrowing Request in accordance with this Section 2.03, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender's Loan to be made as part of the requested Borrowing.

Section 2.04. Interest Elections.

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

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

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

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

(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. If such Interest Election Request does not specify a Type, then the Borrower shall be deemed to have selected a Type of ABR Borrowing.

(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 and Borrowing Base Deficiencies 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 or a Borrowing Base Deficiency has occurred and is continuing: (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing (and any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective) and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

Section 2.05. Funding of Borrowings.

(a) Funding by Lenders. Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 1:00 p.m., Houston, Texas 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 and designated by the Borrower in the applicable Borrowing Request; provided that ABR Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.08(e) shall be remitted by the Administrative Agent to the Issuing Bank. Nothing herein shall be deemed to obligate any Lender to obtain the funds for its Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for its Loan in any particular place or manner.

(b) Presumption of Funding by the Lenders. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender's share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.05(a) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of a payment to be made by 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 and (ii) in the case of a payment to be made by the Borrower, the interest rate applicable to ABR Loans. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable Borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender's Loan included in such Borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

(c) Several Obligations of Lenders. The obligations of the Lenders hereunder to make Loans, to fund participations in Letters of Credit and to make payments pursuant to Section 12.03(c) are several and not joint. The failure of any Lender to make any Loan, to fund any such participation or to make any payment under Section 12.03(c) on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan, to purchase its participation or to make its payment under Section 12.03(c).

Section 2.06. Termination and Reduction of the Aggregate Commitments.

(a) Scheduled Termination of Aggregate Commitments. Unless previously terminated, the Aggregate Commitments shall terminate on the Maturity Date. If at any time either or both of the Aggregate Maximum Credit Amounts or the Borrowing Base is terminated or reduced to zero, then the Aggregate Commitments shall terminate on the effective date of such termination or reduction.

(b) Optional Termination and Reduction of Aggregate Commitments.

(i) The Borrower may at any time terminate, or from time to time reduce, the Aggregate Commitments; provided that (A) each reduction of the Aggregate Commitments shall be in an amount that is an integral multiple of $500,000 and not less than $2,500,000 and (B) the Borrower shall not terminate or reduce the Aggregate Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 3.04(c), the total Revolving Credit Exposures for all Lenders would exceed the lesser of (I) the Aggregate Commitments and (II) the then effective Borrowing Base.

(ii) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Aggregate Commitments under Section 2.06(b)(i) at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section 2.06(b)(ii) shall be irrevocable. Any termination or reduction of the Aggregate Commitments shall be permanent and may not be reinstated. Each reduction of the Aggregate Commitments shall be made ratably among the Lenders in accordance with each Lender's Applicable Percentage.

(iii) The Borrower may terminate the unused amount of the Commitment of a Defaulting Lender upon not less than two (2) Business Days’ prior notice to the Administrative Agent (which will promptly notify the Lenders thereof), and in such event the provisions of Section 2.13(a)(i)(C) will apply to all amounts thereafter paid by the Borrower for the account of such Defaulting Lender under this Agreement (whether on account of principal, interest, fees, indemnity or other amounts), provided that such termination will not be deemed to be a waiver or release of any claim the Borrower, the Administrative Agent, the Issuing Bank or any Lender may have against such Defaulting Lender.

Section 2.07. Borrowing Base.

(a) Borrowing Base. The term "Borrowing Base" means, as of the date of the determination thereof, the designated loan value as calculated by the Lenders in their sole discretion assigned to the discounted present value of future net income accruing to the Mortgaged Property, based upon the Lenders' in-house evaluation of the Mortgaged Property. The Lenders' determination of the Borrowing Base will be made in accordance with then-current practices, economic and pricing parameters, methodology, assumptions, and customary procedures and standards established by each Lender from time to time for its petroleum industry customers. Borrower acknowledges that the determination of the Borrowing Base contains an equity cushion (market value in excess of loan amount) which Borrower acknowledges to be essential for the adequate protection of the Lenders. For the period from the Effective Date to but excluding the next Redetermination Date, the amount of the Borrowing Base shall be $765,000,000.

(b) Scheduled and Interim Redeterminations. The Borrowing Base shall be redetermined semi-annually in accordance with this Section 2.07 (a "Scheduled Redetermination"), and, subject to Section 2.07(d), such redetermined Borrowing Base shall become effective and applicable to the Borrower, the Agents, the Issuing Bank and the Lenders on April 1st and October 1st of each year, provided that the first such Scheduled Redetermination shall occur on December 1, 2011 but then shall continue with the next such Scheduled Redetermination date on April 1, 2012. In addition, the Borrower may, by notifying the Administrative Agent thereof, not more than two (2) times during any 12-month period, and the Administrative Agent may at any time but not more than two (2) times during any 12-month period by notifying the Borrower thereof, at the direction of the Determining Lenders, each elect to cause the Borrowing Base to be redetermined between Scheduled Redeterminations (an "Interim Redetermination") in accordance with this Section 2.07. In addition to the two times during any 12-month period provided in the preceding sentence, the Administrative Agent may, by notifying the Borrower thereof, elect to cause a redetermination of the Borrowing Base any time (i) a prepayment made by the Borrower pursuant to Section 3.04(c)(iv) exceeds five percent (5%) of the Borrowing Base then existing at the time of prepayment, and (ii) any Swap Agreement which has been taken into account in connection with the then current Borrowing Base is closed out and the Swap Termination Value determined in accordance therewith exceeds five percent (5%) of such Borrowing Base.

(i) Each Scheduled Redetermination and each Interim Redetermination shall be effectuated as follows: Upon receipt by the Administrative Agent of (A) the Reserve Report and the certificate required to be delivered by the Borrower to the Administrative Agent, in the case of a Scheduled Redetermination, pursuant to Section 8.12(a) and (c), and, in the case of an Interim Redetermination, pursuant to Section 8.12(b) and (c), and (B) such other reports, data and supplemental information, including, without limitation, the information provided pursuant to Section 8.12(c), as may, from time to time, be reasonably requested by the Required Lenders (the Reserve Report, such certificate and such other reports, data and supplemental information being the "Engineering Reports"), the Administrative Agent shall evaluate the information contained in the Engineering Reports and shall, in good faith, propose a new Borrowing Base (the "Proposed Borrowing Base") based upon such information and such other information (including, without limitation, the status of title information with respect to the Oil and Gas Properties as described in the Engineering Reports and the existence of any other Debt) as the Administrative Agent deems appropriate in its sole discretion and consistent with its normal oil and gas lending criteria as it exists at the particular time. In no event shall the Proposed Borrowing Base exceed the lesser of (A) the Aggregate Commitments and (B) the Aggregate Maximum Credit Amounts.

(ii) The Administrative Agent shall notify the Borrower and the Lenders of the Proposed Borrowing Base (the "Proposed Borrowing Base Notice"):

(A) in the case of a Scheduled Redetermination (1) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on or before the March 1st and September 1st of such year following the date of delivery or (2) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then promptly after the Administrative Agent has received complete Engineering Reports from the Borrower and has had a reasonable opportunity to determine the Proposed Borrowing Base in accordance with Section 2.07(c)(i), and in any event, with thirty (30) days after the Administrative Agent has received the required Engineering Reports; and

(B) in the case of an Interim Redetermination, promptly, and in any event, within fifteen (15) days after the Administrative Agent has received the required Engineering Reports.

(iii) Any Proposed Borrowing Base that would increase the Borrowing Base then in effect must be approved by the Borrowing Base Increase Requisite Lenders as provided in this Section 2.07(c)(iii) (and for the avoidance of doubt, if the Proposed Borrowing Base is in excess of the Aggregate Commitments, no Lender is obligated to fund under such new Borrowing Base in excess of its Commitment); and any Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect must be approved by the Required Lenders as provided in this Section 2.07(c)(iii). Upon receipt of the Proposed Borrowing Base Notice, each Lender shall have fifteen (15) days to agree with the Proposed Borrowing Base or disagree with the Proposed Borrowing Base by proposing an alternate Borrowing Base. If, at the

end of such fifteen (15) days, any Lender has not communicated its approval or disapproval in writing to the Administrative Agent, such silence shall be deemed to be an approval of the Proposed Borrowing Base. If, at the end of such 15-day period, the Borrowing Base Increase Requisite Lenders, in the case of a Proposed Borrowing Base that would increase the Borrowing Base then in effect, or the Required Lenders, in the case of a Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect, have approved, as aforesaid, then the Proposed Borrowing Base shall become the new Borrowing Base, effective on the date specified in Section 2.07(d). If, however, at the end of such 15-day period, the Borrowing Base Increase Requisite Lenders or the Required Lenders, as applicable, have not approved, as aforesaid, the Proposed Borrowing Base, then the Administrative Agent shall poll the Lenders to ascertain the highest Borrowing Base then acceptable to the Borrowing Base Increase Requisite Lenders or the Required Lenders, as applicable, and, such amount shall become the new Borrowing Base, effective on the date specified in Section 2.07(d). Notwithstanding the foregoing, for any Proposed Borrowing Base Increase that is approved by the Borrowing Base Increase Requisite Lenders and not approved by all Lenders, such Proposed Borrowing Base Increase will be effective only for the Approving Lenders.

(iv) If any Lender disagrees with the Proposed Borrowing Base Increase (each, a "Dissenting Lender"), then

(A) such Dissenting Lenders will remain at the existing Borrowing Base level and will not participate in the Increase Portion;

(B) the Borrower may, at its sole expense and effort, upon notice to a Dissenting Lender and the Administrative Agent, replace such Dissenting Lender in accordance with the terms of Section 12.18, and

(C) all or any part of such Dissenting Lender's pro rata participation in any Increase Portion may, at the option of each Approving Lender in its sole discretion, be reallocated among such Approving Lenders in a manner, and subject to documentation and terms, in each case acceptable to the Administrative Agent.

(d) Effectiveness of a Redetermined Borrowing Base. After a redetermined Borrowing Base is approved by Borrowing Base Increase Requisite Lenders or the Required Lenders, as applicable, pursuant to Section 2.07(c)(iii), the Administrative Agent shall notify the Borrower and the Lenders of the amount of the redetermined Borrowing Base (the "New Borrowing Base Notice"), and such amount shall become the new Borrowing Base, effective and applicable to the Borrower, the Administrative Agent, the Issuing Bank and the Lenders:

(i) in the case of a Scheduled Redetermination, (A) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on the April 1st or October 1st, as applicable, following such notice, or (B) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on the Business Day next succeeding delivery of such notice; and

(ii) in the case of an Interim Redetermination, on the Business Day next succeeding delivery of such notice.

Such amount shall then become the Borrowing Base until the next Scheduled Redetermination Date, the next Interim Redetermination Date or the next adjustment to the Borrowing Base under Section 2.07(e), whichever occurs first. Notwithstanding the foregoing, no Scheduled Redetermination or Interim Redetermination shall become effective until the New Borrowing Base Notice related thereto is received by the Borrower.

(e) Borrowing Base Reductions.

(i) In the event of an issuance of any Senior Notes, then the then effective Borrowing Base shall be reduced immediately, automatically and without notice by an amount equal to twenty percent (20%) of the stated principal amount of such issued Senior Notes.

(ii) If any Swap Agreement is terminated or not fully performed for any reason, the Borrowing Base shall be reduced by the amount of the Recognized Value given such Swap Agreement in the then current Borrowing Base as determined by the Administrative Agent or the Required Lenders in their discretion in accordance with the standards set forth in Section 2.07(a). Any such reduction shall not be considered a special determination requested by the Administrative Agent within the meaning specified in Section 2.07(b).

(iii) The Borrowing Base shall be reduced in the event of an Asset Disposition as provided in Section 9.12(d). Any such reduction shall not be considered a special determination requested by the Administrative Agent within the meaning of Section 2.07(b).

(iv) The Borrowing Base may be reduced as provided in Section 8.13(c).

Section 2.08. Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of dollar denominated Letters of Credit for its own account or for the account of any of the Subsidiaries, in a form reasonably acceptable to the Administrative Agent and the Issuing Bank, at any time and from time to time during the Availability Period; provided that the Borrower may not request the issuance, amendment, renewal or extension of Letters of Credit hereunder if a Borrowing Base Deficiency exists at such time or would exist as a result thereof. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control. All Existing Letters of Credit shall be deemed to have been issued pursuant hereto, and from and after the Effective Date, shall be subject to and governed by, the terms and conditions hereof.

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an

outstanding Letter of Credit), the Borrower shall hand deliver or facsimile (or transmit by electronic communication, if arrangements for doing so have been approved by the Issuing Bank) to the Issuing Bank and the Administrative Agent (not less than three (3) Business Days in advance of the requested date of issuance, amendment, renewal or extension) a notice:

(i) requesting the issuance of a Letter of Credit or identifying the Letter of Credit to be amended, renewed or extended;

(ii) specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day);

(iii) specifying the date on which such Letter of Credit is to expire (which shall comply with Section 2.08(c));

(iv) specifying the amount of such Letter of Credit;

(v) specifying the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit; and

(vi) specifying the amount of the then effective Borrowing Base and whether a Borrowing Base Deficiency exists at such time, the current total Revolving Credit Exposures (without regard to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit) and the pro forma total Revolving Credit Exposures (giving effect to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit).

Each notice shall constitute a representation that after giving effect to the requested issuance, amendment, renewal or extension, as applicable, (i) the LC Exposure shall not exceed the LC Commitment and (ii) the total Revolving Credit Exposures for all Lenders shall not exceed the lesser of (A) the Aggregate Commitments and (B) the then effective Borrowing Base.

If requested by the Issuing Bank, the Borrower also shall submit a letter of credit application on the Issuing Bank's standard form in connection with any request for a Letter of Credit.

The Issuing Bank shall not be under any obligation to issue any Letter of Credit if there is a default of any Lender's obligations to fund under Section 2.08(d) or any Lender is at such time a Defaulting Lender hereunder, unless the Issuing Bank has entered into satisfactory arrangements with the Borrower or such Lender to eliminate the Issuing Bank's risk with respect to such Defaulting Lender.

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is five Business Days prior to the Maturity Date; provided, however, that a Letter of Credit may, upon the request of the Borrower, include a provision whereby such Letter of Credit shall be renewed automatically for additional consecutive periods of 12 months or less (but not beyond the date that is five Business Days prior to the Maturity

Date) unless the Issuing Bank notifies the beneficiary thereof at least 30 days (or such longer period as may be specified in such Letter of Credit) prior to the then-applicable expiration date that such Letter of Credit will not be renewed.

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

(e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on the date that such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 12:00 noon, New York City time, on (i) the Business Day that the Borrower receives such notice, if such notice is received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that if such LC Disbursement is not less than $1,000,000, the Borrower shall, subject to the conditions to Borrowing set forth herein, be deemed to have requested, and the Borrower does hereby request under such circumstances, that such payment be financed with an ABR Borrowing in an equivalent amount and, to the extent so financed, the Borrower's obligation to make such payment shall be discharged and replaced by the resulting ABR Borrowing. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender's Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.05 with respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this Section 2.08(e), the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments

pursuant to this Section 2.08(e) to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this Section 2.08(e) to reimburse the Issuing Bank for any LC Disbursement (other than the funding of ABR Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

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

(g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by facsimile) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure

to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Lenders with respect to any such LC Disbursement.

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

(i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 3.05(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term "Issuing Bank" shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. From and after the effective date of any such replacement, the retiring Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement and the other Loan Documents with respect to Letters of Credit issued by it prior to such resignation, but shall not be required to issue additional Letters of Credit or to extend, renew or increase any existing Letter of Credit, including, without limitation, any Letter of Credit with an auto-extend feature (for the avoidance of doubt, the retiring Issuing Bank is authorized to notify any and each beneficiary of each Letter of Credit (in accordance with the terms of such Letter of Credit) that any such Letter of Credit will not be renewed, extended or increased, automatically or otherwise). Upon the acceptance of a successor's appointment as Administrative Agent hereunder, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Issuing Bank, (b) the retiring Issuing Bank and shall be discharged from all of their respective duties and obligations hereunder or under the other Loan Documents, and (c) the successor Issuing Bank shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to the retiring Issuing Bank to effectively assume the obligations of the retiring Issuing Bank with respect to such Letters of Credit.

(j) Cash Collateralization. If (i) any Event of Default shall occur and be continuing and the Borrower receives notice from the Administrative Agent or the Required Lenders demanding the deposit of cash collateral pursuant to this Section 2.08(j), or (ii) the Borrower is required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then the Borrower shall deposit, in an LC Collection Account, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to, in the case of an Event of Default, the LC

Exposure, and in the case of a payment required by Section 3.04(c), the amount of such excess as provided in Section 3.04(c), as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower or any Subsidiary described in Section 10.01(h) or Section 10.01(i). The Borrower hereby grants to the Administrative Agent, for the benefit of the Issuing Bank and the Lenders, an exclusive first priority and continuing perfected security interest in and Lien on the LC Collection Account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in the LC Collection Account, all deposits or wire transfers made thereto, any and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise payable in respect of, or in exchange for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. The Borrower's obligation to deposit amounts pursuant to this Section 2.08(j) shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower or any of the Subsidiaries may now or hereafter have against any such beneficiary, the Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such deposit shall be held as collateral securing the payment and performance of the Borrower's and the Guarantors' obligations under this Agreement and the other Loan Documents. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over the LC Collection Account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower's risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in the LC Collection Account. Moneys in the LC Collection Account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated, be applied to satisfy other obligations of the Borrower and the Guarantors under this Agreement or the other Loan Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, and the Borrower is not otherwise required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived. If the Borrower is required to provide an amount in cash collateral hereunder as a result of any prepayment pursuant to Section 3.04(c) and the Borrower is not otherwise required to pay to the Administrative Agent an amount equal to the LC Exposure as a result of the occurrence of an Event of Default, then if the total Revolving Credit Exposure is reduced (whether pursuant to Section 3.04(a), the expiration of Letters of Credit or otherwise) and/or the Borrowing Base is increased in accordance with Section 2.07, as a result of which a Borrowing Base Deficiency no longer exists and so long no Default has occurred and is continuing, the Administrative Agent shall return to the Borrower

such amount but only to the extent that the then effective Borrowing Base exceeds the total Revolving Credit Exposures by not less than $1,000,000.

Section 2.09. Collateral.

(a) Mortgaged Property. The payment and performance of all of the Obligations hereunder and under the Loan Documents, and under the Secured Swap Agreements and Secured Treasury Management Agreements, and the reimbursement obligations under the Letters of Credit, shall be secured by a first and superior Lien against the entire interest of the Borrower and each Subsidiary in certain of their Oil and Gas Properties (in an amount sufficient to comply with the requirements of Section 8.14), pursuant to the terms of one or more Mortgages in favor of the Administrative Agent for the ratable benefit of the Secured Parties, which Mortgages shall be satisfactory in form and substance to the Administrative Agent.

(b) Guarantees and Personal Property Assets. The payment and performance of all of the Obligations hereunder, under the Loan Documents, and under the Secured Swap Agreements and Secured Treasury Management Agreements, and the reimbursement obligations under the Letters of Credit, (A) shall be unconditionally guaranteed by each Subsidiary pursuant to one or more Guaranty Agreements, and (B) shall be secured by a first priority Lien against all personal property assets of the Borrower and of each Subsidiary pursuant to a Security Agreement. Reference is made to Section 8.14 of this Agreement for further provisions with respect to additional Guarantors and additional collateral.

Section 2.13. Defaulting Lenders.

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

(i) Reallocation of Defaulting Lender Commitment, Etc. If a Lender becomes, and during the period it remains, a Defaulting Lender, the following provisions shall apply with respect to any outstanding LC Exposure of such Defaulting Lender:

(A) the LC Exposure of such Defaulting Lender will, subject to the limitation in the first and second proviso below, automatically be reallocated (effective on the day such Lender becomes a Defaulting Lender) among the Non-Defaulting Lenders pro rata in accordance with their respective Commitments; provided that (I) the sum of each Non-Defaulting Lender’s Revolving Credit Exposure may not in any event exceed the lesser of (x) the Commitment of such Non-Defaulting Lender as in effect at the time of such reallocation and (y) such Non-Defaulting Lender's Applicable Percentage of the Borrowing Base as in effect at the time of such reallocation, (II) there exists no Default at such time of reallocation and (III) neither such reallocation nor any payment by a Non-Defaulting Lender pursuant thereto will constitute a waiver or release of any claim the Borrower, the Administrative Agent, the Issuing Bank or any other Lender may have against such Defaulting Lender or cause such Defaulting Lender to be a Non-Defaulting Lender;

(B) to the extent that any portion (the "unreallocated portion") of the Defaulting Lender’s LC Exposure cannot be so reallocated, whether by reason of the first provisos in clause (I) or (II) preceding or otherwise, the Borrower will, not later than two (2) Business Days after demand by the Administrative Agent (at the direction of the Issuing Bank),

(I) Cash Collateralize the obligations of the Borrower to the Issuing Bank in respect of such LC Exposure, in an amount at least equal to the aggregate amount of the unreallocated portion of such LC Exposure, or (II) make other arrangements satisfactory to the Administrative Agent, and to the Issuing Bank, in their sole discretion to protect them against the risk of non-payment by such Defaulting Lender; and

(C) any amount paid by the Borrower or otherwise received by the Administrative Agent for the account of a Defaulting Lender under this Agreement (whether on account of principal, interest, fees, indemnity payments or other amounts) will not be paid or distributed to such Defaulting Lender, but will instead be retained by the Administrative Agent in a segregated non-interest bearing account until (subject to Section 2.13(b)) the termination of the Aggregate Commitments and payment in full of all obligations of the Borrower hereunder and will be applied by the Administrative Agent, to the fullest extent permitted by law, to the making of payments from time to time in the following order of priority: first to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent under this Agreement, second to the payment of any amounts owing by such Defaulting Lender to the Issuing Bank (pro rata as to the respective amounts owing to each of them) under this Agreement, third to the payment of post-default interest and then current interest due and payable to the Lenders hereunder other than Defaulting Lenders, ratably among them in accordance with the amounts of such interest then due and payable to them, fourth to the payment of fees then due and payable to the Non-Defaulting Lenders hereunder, ratably among them in accordance with the amounts of such fees then due and payable to them, fifth to pay principal and unreimbursed LC Disbursements then due and payable to the Non-Defaulting Lenders hereunder ratably in accordance with the amounts thereof then due and payable to them, sixth to the ratable payment of other amounts then due and payable to the Non-Defaulting Lenders, and seventh after the termination of the Aggregate Commitments and payment in full of all obligations of the Borrower hereunder, to pay amounts owing under this Agreement to such Defaulting Lender or as a court of competent jurisdiction may otherwise direct.

(ii) Right to Give Drawdown Notices. In furtherance of the foregoing, if any Lender becomes, and during the period it remains, a Defaulting Lender or a Potential Defaulting Lender, each of the Issuing Bank is hereby authorized by the Borrower (which authorization is irrevocable and coupled with an interest) to give, in its discretion, through the Administrative Agent, Notices of Borrowing pursuant to Section 2.03 in such amounts and in such times as may be required to (A) reimburse an outstanding LC Disbursement, and/or (B) Cash Collateralize the obligations of the Borrower in respect of outstanding Letters of Credit in an amount at least equal to the aggregate amount of the obligations (contingent or otherwise) of such Defaulting Lender or Potential Defaulting Lender in respect of such Letter of Credit.

(iii) Certain Fees. Anything herein to the contrary notwithstanding, during such period as a Lender is a Defaulting Lender, such Defaulting Lender will not be entitled to any fees accruing during such period pursuant to Section 3.05(a) and Section 3.05(b)(i) (without prejudice to the rights of the Non-Defaulting Lenders in respect of such fees), provided that (a) to the extent that all or a portion of the LC Exposure of such Defaulting Lender is reallocated to the Non-Defaulting Lenders pursuant to Section 2.13(a)(i)(A), such fees that would have accrued for the benefit of such Defaulting Lender will instead accrue for the benefit of and be payable to such Non-Defaulting Lenders, pro

rata in accordance with their respective Commitments, and (b) to the extent that all or any portion of such LC Exposure cannot be so reallocated, such fees will instead accrue for the benefit of and be payable to the Issuing Bank, as applicable (and the pro rata payment provisions of this Agreement (including without limitation, Article IV) will automatically be deemed adjusted to reflect the provisions of this Section).

(b) Defaulting Lender Cure. If the Borrower, the Administrative Agent and the Issuing Bank agree in writing in their discretion that a Lender is no longer a Defaulting Lender or a Potential Defaulting Lender, as the case may be, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any amounts then held in the segregated account referred to in Section 2.13(a)(i)), such Lender will, to the extent applicable, purchase at par such portion of outstanding Loans of the other Lenders and/or make such other adjustments as the Administrative Agent may determine to be necessary to cause the Revolving Credit Exposure and LC Exposure of the Lenders to be on a pro rata basis in accordance with their respective Commitments, whereupon such Lender will cease to be a Defaulting Lender or Potential Defaulting Lender and will be a Non-Defaulting Lender (and such Revolving Credit Exposure and LC Exposure of each Lender will automatically be adjusted on a prospective basis to reflect the foregoing); provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while such Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender or Potential Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender or Potential Defaulting Lender.

ARTICLE III

Payments of Principal and Interest; Prepayments; Fees

Section 3.01. Repayment of Loans. The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan on the Termination Date.

Section 3.02. Interest.

(a) ABR Loans. The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

(b) Eurodollar Loans. The Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

(i) if any principal of or interest on any Loan or any fee or other amount payable by the Borrower or any Guarantor hereunder or under any other Loan Document is not paid when due, whether at stated maturity, upon acceleration or otherwise, and including

any payments in respect of a Borrowing Base Deficiency under Section 3.04(c) or otherwise, then all Loans outstanding shall bear interest, after as well as before judgment, at a rate per annum equal to three percent (3%) plus the rate applicable to ABR Loans as provided in Section 3.02(a), but in no event to exceed the Highest Lawful Rate, and

(ii) if there exists any Event of Default, then all Loans outstanding shall, at the option of the Administrative Agent or the Required Lenders, bear interest, after as well as before judgment, at a rate per annum equal to three percent (3%) plus the rate applicable to ABR Loans as provided in Section 3.02(a), but in no event to exceed the Highest Lawful Rate, and

(iii) during any Borrowing Base Deficiency (after the expiration of the 30-day period provided in Section 3.04(c)(ii), as applicable), all Loans outstanding at such time shall bear interest, after as well as before judgment, at the rate then applicable to such Loans, plus the Applicable Margin, if any, plus an additional three percent (3%), but in no event to exceed the Highest Lawful Rate.

(d) Interest Payment Dates. Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and on the Termination Date; provided that (i) interest accrued pursuant to Section 3.02(c) shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than an optional prepayment of an ABR Loan prior to the Termination Date), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment, and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

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

Section 3.03. Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

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

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

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

Section 3.04. Prepayments.

(a) Optional Prepayments. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with Section 3.04(b).

(b) Notice and Terms of Optional Prepayment. The Borrower shall notify the Administrative Agent by telephone (confirmed by facsimile) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 11:00 a.m., Houston, Texas time, three Business Days before the date of prepayment, or (ii) in the case of prepayment of an ABR Borrowing, not later than 11:00 a.m. Houston, Texas time, one Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 3.02.

(i) If, after giving effect to any termination or reduction of the Aggregate Commitments pursuant to Section 2.06(b), the total Revolving Credit Exposures exceeds the lesser of (x) the Aggregate Commitments and (y) the Borrowing Base then in effect, then the Borrower shall (A) prepay the Borrowings on the date of such termination or reduction in an aggregate principal amount equal to such excess, and (B) if any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as Cash Collateral as provided in Section 2.08(j).

(ii) If, upon any redetermination of or adjustment to the amount of the Borrowing Base in accordance with Section 2.07 or pursuant to Section 8.13(c), a Borrowing Base Deficiency exists, then the Borrower shall either prepay the Borrowings in an aggregate principal amount equal to such deficiency, or provide additional Mortgaged Property to secure Obligations having a Recognized Value equal to or greater than the amount of such deficiency (or the remaining balance of such deficiency after any prepayments), and if any deficiency remains after prepaying all of the Borrowings or providing additional Mortgaged Property as a result of any LC Exposure, the Borrower shall pay to the Administrative Agent on behalf of the

Lenders an amount equal to such deficiency to be held as Cash Collateral as provided in Section 2.08(j). The Borrower shall be obligated to make any such principal prepayment or deposit of Cash Collateral in an amount equal to such deficiency within 30 days, or in six monthly installments beginning within 30 days, following its receipt of the New Borrowing Base Notice in accordance with Section 2.07(d) or the date the adjustment occurs, and/or to provide additional Mortgaged Property within 30 days following its receipt of such New Borrowing Base Notice or the date such adjustment occurs; provided that all payments and/or deposits required to be made pursuant to this Section 3.04(c)(ii) must be made on or prior to the Termination Date.

(iii) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied, first, ratably to any ABR Borrowings then outstanding, and, second, to any Eurodollar Borrowings then outstanding, and if more than one Eurodollar Borrowing is then outstanding, to each such Eurodollar Borrowing in order of priority beginning with the Eurodollar Borrowing with the least number of days remaining in the Interest Period applicable thereto and ending with the Eurodollar Borrowing with the most number of days remaining in the Interest Period applicable thereto.

(iv) If any Swap Agreement is closed out and the Swap Termination Value determined in accordance therewith is paid to the Borrower or any Subsidiary, then (A) the Borrower shall prepay the Borrowings in an aggregate principal amount equal to such Swap Termination Value, and (B) if any excess remains after prepaying all such Borrowings, the Borrower shall then pay to the Administrative Agent on behalf of all of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.08(j); provided, however, this Section 3.04(c)(iv) shall not apply to the extent that, within two (2) Business Days of the date such Swap Agreement is closed out, the Borrower or any Subsidiary expends amounts that would be otherwise payable by the Borrower under this Section 3.04(c)(iv) to enter into Swap Agreements with an aggregate present value at least equivalent to the closed-out Swap Agreement, with the entry into such replacement Swap Agreements being deemed a representation by the Borrower of such equivalent present value. The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral on the later of (i) the date it or any Subsidiary receives the cash payment of the Swap Termination Value for the closed out Swap Agreement, and (ii) two (2) Business Days after the date such Swap Agreement is closed out.

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

(d) No Premium or Penalty. Prepayments permitted or required under this Section 3.04 shall be without premium or penalty, except as required under Section 5.02.

(e) No Effect on Secured Swap Agreements. Prepayments permitted or required under this Section 3.04 shall not affect the Borrower's obligation to continue making payments under any Secured Swap Agreement or Secured Treasury Management Agreement, each of which shall remain in full force and effect notwithstanding such prepayment, subject to the terms of such Secured Swap Agreement and/or Secured Treasury Management Agreement.

Section 3.05. Fees.

(a) Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee, which shall accrue at the applicable Commitment Fee Rate on the average daily amount of the unused amount of the Commitment of such Lender during the period from and including the Effective Date to but excluding the Termination Date. Accrued commitment fees shall be payable in arrears on the last day of March, June, September and December of each year and on the Termination Date, commencing on the first such date to occur after the date hereof. All commitment fees shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(b) Letter of Credit Fees. The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at a per annum rate equal to the Letter of Credit Fee Rate in effect on the average daily amount of such Lender's LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender's Commitment terminates and the date on which such Lender ceases to have any LC Exposure, (ii) to the Issuing Bank a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, provided that in no event shall such fee be less than $500 during any quarter, and (iii) to the Issuing Bank, for its own account, its standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable on the third Business Day following such last day, commencing on the first such date to occur after the Effective Date; provided that all such fees shall be payable on the Termination Date and any such fees accruing after the Termination Date shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this Section 3.05(b) shall be payable within 10 days after demand. All fronting fees in Section 3.05(b)(ii) shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). All other fees in this Section 3.05(b) shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate in which case such fee shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(i) Loan Origination Fee. The Borrower shall pay each Lender on the Effective Date a loan origination fee based upon the final allocation of such Lender's Commitment in accordance with the following:

Lender's Final Commitment	Fee
$100,000,000	0.50%
$75,000,000	0.45%
$50,000,000	0.40%

For avoidance of doubt, if a Lender commits to a $100,000,000 Commitment and then its Commitment gets reduced to $80,000,000 at closing based upon final allocations of the Aggregate Commitments, the loan origination fee will be 0.50% times $80,000,000.

(ii) Increase of Borrowing Base. The Borrower agrees to pay the Administrative Agent for the account of each Approving Lender a fee for each incremental increase in the new Borrowing Base over the previous maximum Borrowing Base. The amount of each fee shall be the same percentage specified in subsection (i) preceding times the amount of each Approving Lender's Applicable Percentage of the incremental increase of the Borrowing Base, in each case calculated on a pro-rated basis over the remaining term of the Loans, as ratably adjusted for any reallocation of an Increase Portion in accordance with the terms of Section 2.07(c)(iv)(B). Such fee shall be due and payable on the effective date of any such increase.

(d) Administrative Agent Fees. The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent.

ARTICLE IV

Payments; Pro Rata Treatment; Sharing of Set-offs

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

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

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

(c) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or other obligations hereunder resulting in such Lender receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall

(i) notify the Administrative Agent of such fact, and

(ii) purchase (for cash at face value) participations in the Loans and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them; provided that

(A) 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

(B) the provisions of this Section 4.01(c) shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this Section 4.01(c) shall apply).

Each Loan Party consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against each Loan Party rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of each Loan Party in the amount of such participation.

Section 4.02. Presumption of Payment by the Borrower. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such

assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

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), Section 2.08(d), Section 2.08(e) or Section 4.02 then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender's obligations under such Sections until all such unsatisfied obligations are fully paid.

Section 4.04. Disposition of Proceeds. The Security Instruments contain an assignment by the Borrower and/or the Guarantors unto and in favor of the Administrative Agent for the benefit of the Secured Parties of all of the Borrower's or each Guarantor's interest in and to production and all proceeds attributable thereto which may be produced from or allocated to the Mortgaged Property. The Security Instruments further provide in general for the application of such proceeds to the satisfaction of the 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 the 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 Subsidiaries.

ARTICLE V

Increased Costs; Break Funding Payments; Taxes; Illegality

Section 5.01. Increased Costs.

(a) Increased Costs, Generally. If any Change in Law shall:

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

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

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

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

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

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

(d) Delay in Requests. Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender's or the Issuing Bank's right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section 5.01 for any increased costs incurred or reductions suffered more than 270 days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender's or the Issuing Bank's intention to claim compensation therefor (except that, if the Change in Law

giving rise to such increased costs or reductions is retroactive, then the 270 day period referred to above shall be extended to include the period of retroactive effect thereof).

(e) Protection Absolute. The protection of this Section shall be available to each Lender and the Issuing Bank regardless of any possible contention of the invalidity or inapplicability of the Change in Law that shall have occurred or been imposed.

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 shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

Section 5.03. Taxes.

(a) Issuing Bank. For purposes of this Section 5.03, the term "Lender" includes the Issuing Bank.

(b) Payments Free of Taxes. Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Loan Party shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional

sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

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

(d) Indemnification by the Borrower and the Other Loan Parties. The Loan Parties shall jointly and severally indemnify each Recipient, within 10 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e) Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that any Loan Party has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Loan Parties to do so), (ii) any Taxes attributable to such Lender's failure to comply with the provisions of Section 12.04 relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (e).

(f) Evidence of Payments. As soon as practicable after any payment of Taxes by any Loan Party to a Governmental Authority pursuant to this Section 5.03, such Loan Party shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(g) Status of Lenders.

(i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments

to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 5.03(g)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender's reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii) Without limiting the generality of the foregoing,

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

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

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

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

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

(IV) to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI,

IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-2 or Exhibit G-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-4 on behalf of each such direct and indirect partner;

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

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

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so.

(h) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 5.3 (including by the payment of additional amounts pursuant to this Section 5.3), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such

refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

Section 5.04. Mitigation Obligations; Replacement of Lenders.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 5.01, or requires the Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.3, then such Lender shall (at the request of the Borrower) 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 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 any Lender requests compensation under Section 5.01, or if the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03 and, in each case, such Lender has declined or is unable to designate a different lending office in accordance with Section 5.04(a), or if any Lender is a Defaulting Lender, or a Dissenting Lender or a Non-Consenting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, replace such Lender in accordance with the terms of Section 12.18.

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.

(a) Each of the Borrower and the Subsidiaries has good and defensible title to the Oil and Gas Properties evaluated in the most recently delivered Reserve Report, and each Loan Party has 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 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 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 Subsidiary's net revenue interest in such Property. The ownership by the Borrower or any Subsidiary of the Hydrocarbons and the undivided interests therein specified on the exhibits to the Mortgages are the same interests reflected in the most recently delivered Reserve Report.

(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 have a Material Adverse Effect.

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

(d) All of the Properties of the Borrower and the 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, in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. The Borrower and the 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, and subject to the prior rights and limitations of Borrower as an owner of non-operated working interests, the Oil and Gas Properties (and Properties unitized therewith) of the Borrower and the Subsidiaries have been maintained, operated and developed in a good and workmanlike manner and in conformity with all Governmental Requirements and in conformity with the provisions of all leases, subleases or other contracts comprising a part of the Hydrocarbon Interests and other contracts and agreements forming a part of the Oil and Gas Properties of the Borrower and the Subsidiaries. Specifically in connection with the foregoing, except for those as could not be reasonably

expected to have a Material Adverse Effect, (i) no Oil and Gas Property of the Borrower or any Subsidiary is subject to having allowable production reduced below the full and regular allowable (including the maximum permissible tolerance) because of any overproduction (whether or not the same was permissible at the time) and (ii) none of the ▇▇▇▇▇ comprising a part of the Oil and Gas Properties (or Properties unitized therewith) of the Borrower or any Subsidiary is deviated from the vertical more than the maximum permitted by Governmental Requirements (except with respect to horizontal ▇▇▇▇▇ permitted by Governmental Authority), and such ▇▇▇▇▇ 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 ▇▇▇▇▇ located on Properties unitized therewith, such unitized Properties) of the Borrower or such Subsidiary. All pipelines, ▇▇▇▇▇, gas processing plants, platforms and other material improvements, fixtures and equipment owned in whole or in part by the Borrower or any of the Subsidiaries that are necessary to conduct normal operations are being maintained in a state adequate to conduct normal operations, and with respect to such of the foregoing which are operated by the Borrower or any of the Subsidiaries, in a manner consistent with the Borrower's or the Subsidiaries' past practices (other than those the failure of which to maintain in accordance with this Section 7.17 could not reasonably be expected to have a Material Adverse Effect).

Section 7.18. Gas Imbalances, Prepayments. Except as set forth on Schedule 7.18 or on the most recent certificate delivered pursuant to Section 8.12(c), on a net basis there are no Material Gas Imbalances, take or pay or other prepayments which would require the Borrower or any of the Subsidiaries to deliver Hydrocarbons produced from the Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor.

Section 7.19. Marketing of Production. Except for contracts listed and in effect on the date hereof 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 the 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 Subsidiaries' Hydrocarbons (including, without limitation, calls on or other rights to purchase, production, whether or not the same are currently being exercised) that (a) pertain to the sale of production at a fixed price and (b) have a maturity or expiry date of longer than six (6) months from the date hereof.

Section 7.20. Swap Agreements. Schedule 7.20, as of the date hereof, and after the date hereof, each report required to be delivered by the Borrower pursuant to Section 8.01(f), sets forth, a true and complete list of all Swap Agreements of the Borrower and each Subsidiary, the material terms thereof (including the type, term, effective date, termination date and notional amounts or volumes), the net ▇▇▇▇ to market value thereof, all credit support agreements relating thereto (including any margin required or supplied) and the counterparty to each such agreement, including specification as to those Swap Agreements that are Secured Swap Agreements.

Section 7.21. Use of Loans and Letters of Credit. The proceeds of the Loans and the Letters of Credit shall be used (a) to provide working capital for exploration and production

operations, (b) to pay fees and expenses related to the Transaction, (c) to effect the ENP Transaction in accordance with the terms of the ENP Transaction Documents; (d) to refinance Debt owed by ENP Operating under the ENP Credit Agreement, (e) to refinance Debt of the Borrower under the Term Loan Credit Facility, (f) to finance the Borrower's Capital Expenditures, including capital projects and additional acquisitions, in each case to the extent permitted by the terms of this Agreement and (g) for other lawful corporate purposes. In addition, the Borrower may use the proceeds of Loans to make Restricted Payments to the holders of its Equity Interests provided (i) the aggregate amount of the Restricted Payment does not exceed the Borrower's EBITDA for the immediately preceding fiscal quarter; and (ii) the Restricted Payment is otherwise permitted by Section 9.04(e).

The Parent, the Borrower and the Subsidiaries are not engaged principally, or as one of its or their important activities, in the business of extending credit for the purpose, whether immediate, incidental or ultimate, of buying or carrying margin stock (within the meaning of Regulation T, U or X of the Board). No part of the proceeds of any Loan or Letter of Credit will be used for any purpose which violates the provisions of Regulations T, U or X of the Board.

Section 7.22. Solvency. After giving effect to the transactions contemplated hereby, (a) the aggregate assets (after giving effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any similar arrangement), at a fair valuation, of the Borrower and the Guarantors, taken as a whole, will exceed the aggregate Debt of the Borrower and the Guarantors on a consolidated basis, as the Debt becomes absolute and matures, (b) each of the Borrower and the Guarantors will not have incurred or intended to incur, and will not believe that it will incur, Debt beyond its ability to pay such Debt (after taking into account the timing and amounts of cash to be received by each of the Borrower and the Guarantors and the amounts to be payable on or in respect of its liabilities, and giving effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any similar arrangement) as such Debt becomes absolute and matures and (c) each of the Borrower and the Guarantors will not have (and will have no reason to believe that it will have thereafter) unreasonably small capital for the conduct of its business.

Section 7.23. Sanctioned Persons. None of the Parent, the Borrower or any Subsidiary or, to the knowledge of the Borrower, any director, officer, agent, employee or Affiliate of the Parent, the Borrower or any Subsidiary is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department ("OFAC"); and the Borrower will not directly or indirectly use the proceeds of the Loans or the Letters of Credit or otherwise make available such proceeds to any Person or entity, for the purpose of financing the activities of any Person currently subject to any U.S. sanctions administered by OFAC.

Section 7.24. Security Instruments. The Mortgages are effective to create in favor of the Administrative Agent, for the ratable benefit of the Secured Parties, a legal, valid and enforceable Lien on all of the Borrower's and each Guarantor's right, title and interest in and to the Mortgaged Property thereunder and the proceeds thereof. The Mortgages (other than the Mortgages covering the ENP Oil and Gas Properties), having been filed in the offices of the counties where such properties are located, constitute a fully perfected Lien on, and security interest in, all right, title and interest of the Borrower and each Guarantor in such Mortgaged Property and the proceeds thereof, in each case prior and superior in right to any other Person,

other than with respect to the rights of persons pursuant to Liens expressly permitted by Section 9.03. When the Mortgages covering the ENP Oil and Gas Properties are filed in the offices of the counties where such properties are located, such Mortgages shall constitute a fully perfected Lien on, and security interest in, all right, title and interest of the Borrower and each Guarantor in the Mortgaged Property thereunder and the proceeds thereof, in each case prior and superior in right to any other Person, other than with respect to the rights of persons pursuant to Liens expressly permitted by Section 9.03. Each Security Agreement is effective to create in favor of the Administrative Agent, for the ratable benefit of the Secured Parties, a legal, valid and enforceable Lien on all of the right, title and interest of each Loan Party executing the same in and to all of the Collateral described therein.

Section 7.25. Article 8 of Uniform Commercial Code. No Equity Interest of Borrower or any Subsidiary is evidenced by a certificate or other instrument. None of the Organizational Documents of Borrower or any Subsidiary provides that any Equity Interest in Borrower or any Subsidiary is a security governed by Article 8 of the Uniform Commercial Code.

(a) On or before the delivery to the Administrative Agent and the Lenders of each Reserve Report required by Section 8.12(a), the Borrower will deliver title information in form and substance acceptable to the Administrative Agent covering enough of the Oil and Gas Properties evaluated by such Reserve Report that were not included in the immediately preceding Reserve Report, so that the Administrative Agent shall have received together with

title information previously delivered to the Administrative Agent, satisfactory title information on at least 80% of the Recognized Value of the Oil and Gas Properties evaluated by such Reserve Report.

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

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 then outstanding Borrowing Base 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 Recognized Value of the Oil and Gas Properties. This new Borrowing Base shall become effective immediately after receipt of such notice.

Section 8.14. Additional Collateral; Additional Guarantors.

(a) In connection with each redetermination of the Borrowing Base, the Borrower shall review the Reserve Report and the list of current Mortgaged Properties (as described in Section 8.12(c)(vi)) to ascertain whether the Mortgaged Properties represent at least 80% of the Recognized Value of the Oil and Gas Properties evaluated in the most recently completed Reserve Report after giving effect to exploration and production activities, acquisitions, dispositions and production. In the event that the Mortgaged Properties do not represent at least 80% of such Recognized Value, then the Borrower shall, and shall cause the Subsidiaries to, grant, within thirty (30) days of delivery of the certificate required under Section 8.12(c), to the Administrative Agent as security for the Obligations a first-priority Lien interest (provided that Excepted Liens of the type described in clauses (a) to (d) and (f) of the definition thereof may exist, but subject to the provisos at the end of such definition) on additional Oil and Gas Properties not already subject to a Lien of the Security Instruments such

that after giving effect thereto, the Mortgaged Properties will represent at least 80% of such Recognized Value. 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 reasonably satisfactory to the Administrative Agent and in sufficient executed (and acknowledged where necessary or appropriate) counterparts for recording purposes. In order to comply with the foregoing, if any Subsidiary places a Lien on its Oil and Gas Properties and such Subsidiary is not a Guarantor, then it shall become a Guarantor and comply with Section 8.14(b).

(b) The Borrower shall promptly cause each Domestic Subsidiary to guarantee the Obligations pursuant to a Guaranty Agreement. In connection with any such guaranty, the Borrower shall, or shall cause such Subsidiary to, (A) pledge all of the Equity Interests of such new Subsidiary pursuant to a Security Agreement (including, without limitation, delivery of original stock certificates, if any, evidencing the Equity Interests of such Subsidiary, together with an appropriate undated stock powers for each certificate duly executed in blank by the registered owner thereof) and (B) execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent.

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. In order to comply with the foregoing, if any Subsidiary places such a Lien on its Oil and Gas Properties and such Subsidiary is not a Guarantor, then it shall become a Guarantor and comply with Section 8.14(b).

(d) In the event that (i) the Required Lenders waive the provisions of Section 9.15 to permit the Borrower or any Domestic Subsidiary to become the owner of a Foreign Subsidiary (such waiver to be granted in the sole discretion of the Required Lenders), and (ii) such Foreign Subsidiary has total assets in excess of $1,000,000, then the Borrower shall promptly, or shall cause such Domestic Subsidiary to promptly, guarantee the Obligations pursuant to the Guaranty Agreement. In connection with any such guaranty, the Borrower shall, or shall cause such Domestic Subsidiary to, (i) execute and deliver a supplement to the Guaranty Agreement, (ii) pledge 65% of all the Equity Interests of such Foreign Subsidiary (including, without limitation, delivery of original stock certificates evidencing such Equity Interests of such Foreign Subsidiary, together with appropriate stock powers for each certificate duly executed in blank by the registered owner thereof) and (iii) execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent.

With respect to each Plan (other than a Multiemployer Plan), the Borrower will, and will cause the Parent and each Subsidiary and ERISA Affiliate to, (i) satisfy in full and in a timely manner, without incurring any late payment or underpayment charge or penalty and without giving rise to any Lien, all of the contribution and funding requirements of section 412 of the Code (determined without regard to subsections (d), (e), (f) and (k) thereof) and of section 302 of ERISA (determined without regard to sections 303, 304 and 306 of ERISA), and (ii) pay, or cause to be paid, to the PBGC in a timely manner, without incurring any late payment or underpayment charge or penalty, all premiums required pursuant to sections 4006 and 4007 of ERISA.

The Borrower will use its reasonable efforts to cause the operator of Properties which the Borrower or any Subsidiary does not operate to comply with the terms and provisions of this Section 9.13.

Section 9.14. Transactions with Affiliates. The Borrower will not, and will not permit the Parent or any Subsidiary to, enter into any transaction, including, without limitation, any purchase, sale, lease or exchange of Property or the rendering of any service, with any Affiliate (other than the Guarantors and Wholly-Owned Subsidiaries of the Borrower) unless such transactions are otherwise permitted under this Agreement and are upon fair and reasonable terms no less favorable to it than it would obtain in a comparable arm's length transaction with a Person not an Affiliate.

Section 9.15. Subsidiaries. The Borrower will not, and will not permit the Parent or any Subsidiary to, create or acquire any additional Subsidiary unless the Borrower gives written notice to the Administrative Agent of such creation or acquisition and complies with Section 8.14(b) and Section 8.14(c); provided however, that the Borrower and any Wholly-Owned Subsidiary may create a Subsidiary to be used in connection with the merger by the Borrower or any Subsidiary with any of their respective Subsidiaries. The Borrower shall not, and shall not permit any Subsidiary to, sell, assign or otherwise dispose of any Equity Interests in

any Subsidiary. None of the Borrower, the Parent or any Subsidiary shall have any Foreign Subsidiaries.

Section 9.16. Negative Pledge Agreements; Dividend Restrictions. The Borrower will not, and will not permit any Subsidiary to, create, incur, assume or suffer to exist any contract, agreement or understanding (other than this Agreement, the Security Instruments or Capital Leases creating Liens permitted by Section 9.03(c)) which in any way prohibits or restricts the granting, conveying, creation or imposition of any Lien on any of its Property in favor of the Administrative Agent and/or any or all of the Secured Parties or restricts any Subsidiary from paying dividends or making distributions to the Borrower or any Guarantor, or which requires the consent of or notice to other Persons in connection therewith.

Section 9.17. Gas Imbalances, Take-or-Pay or Other Prepayments. The Borrower will not, and will not permit any Subsidiary to, (a) incur, become or remain liable for, any Material Gas Imbalance, or (b) allow take-or-pay or other prepayments with respect to the Oil and Gas Properties of the Borrower or any Subsidiary that would require the Borrower or such Subsidiary to deliver Hydrocarbons at some future time without then or thereafter receiving full payment therefor.

Section 9.18. Swap Agreements. The Borrower will not, and will not permit any Subsidiary to, enter into any Swap Agreements with any Person other than

(a) Swap Agreements in respect of commodities (x) with an Approved Counterparty and (y) the notional volumes for which (when aggregated with other commodity Swap Agreements then in effect other than basis differential swaps on volumes already hedged pursuant to other Swap Agreements) do not exceed the greater of, on any five year period beginning any date of determination (and in connection with any transaction described in Section 2.10, after giving effect to such future acquisition on a pro forma basis):

(i) 85% of the projected production of Hydrocarbons from Proved Reserves of the Oil and Gas Properties (as reflected on the most recently delivered Engineering Reports acceptable to the Administrative Agent) during the period in effect for each of crude oil and natural gas, calculated separately, and

(ii) for projected production of Hydrocarbons from the Oil and Gas Properties (as reflected on the most recently delivered Engineering Reports acceptable to the Administrative Agent) constituting PDP only, (x) for the first 24 months following such date, 100% of such reasonably anticipated projected production for each of crude oil and natural gas, calculated separately, and (y) for the period from the 25th month through the 48th month following such date, 90% of such reasonably anticipated projected production for each of crude oil and natural gas, calculated separately, and (z) for such period from the 49th month through the 60th month following such date, 85% of the reasonably anticipated projected production for each of crude oil and natural gas, calculated separately. For purposes of this calculation, the Borrower may, in its discretion, include natural gas liquids production in natural gas or crude oil calculations so long as the Borrower is in compliance with the preceding restrictions. The Borrower may hedge production associated with new acquisitions upon the signing of the applicable purchase and sale agreement so long as (i) the Borrowing Base Utilization Percentage

does not exceed 90% prior to the closing of such acquisition and (ii) should such acquisition fail to close, all derivative transactions associated with the new acquisition will be unwound or otherwise terminated so that the Borrower is in compliance with the hedging restrictions set forth above (such unwinding/termination to be completed within 30 days of the date of the termination of the purchase and sale agreement).

(iii) do not include more than 35% of the projected production of Hydrocarbons from Proved Reserves constituting PDNP or PUD, and

(b) Swap Agreements in respect of interest rates with an Approved Counterparty with the purpose and effect of fixing interest rates on a principal amount of indebtedness of the Borrower that is accruing interest at a variable rate, provided that (i) the aggregate notional amount of such contracts never exceeds 100% of the anticipated outstanding principal balance of the indebtedness to be hedged by such contracts or an average of such principal balances calculated by using a generally accepted method of matching interest rate swap contracts to declining principal balances, and (ii) the floating rate index of each such contract generally matches the index used to determine the floating rates of interest on the corresponding indebtedness to be hedged by such contract. In no event shall any Swap Agreement contain any requirement, agreement or covenant for the Borrower or any Subsidiary to post collateral (other than Letters of Credit) or margin to secure their obligations under such Swap Agreement or to cover market exposures. Should there be a breach of this Section 9.18, the Borrower or any Subsidiary, as applicable, shall promptly unwind, modify, assign or terminate any Swap Agreement as is necessary to cure such breach; provided that nothing contained herein shall be construed to modify or limit the terms of Section 10.01(d).

Section 9.19. Marketing Activities. The Borrower will not, and will not permit any of the Subsidiaries to, engage in marketing activities for any Hydrocarbons or enter into any contracts related thereto other than (i) contracts for the sale of Hydrocarbons scheduled or reasonably estimated to be produced from their proved Oil and Gas Properties during the period of such contract, (ii) contracts for the sale of Hydrocarbons scheduled or reasonably estimated to be produced from proved Oil and Gas Properties of third parties during the period of such contract associated with the Oil and Gas Properties of the Borrower and the Subsidiaries that the Borrower or one of the Subsidiaries has the right to market pursuant to joint operating agreements, unitization agreements or other similar contracts that are usual and customary in the oil and gas business and (iii) other contracts for the purchase and/or sale of Hydrocarbons of third parties (A) which have generally offsetting provisions (i.e. corresponding pricing mechanics, delivery dates and points and volumes) such that no "position" is taken and (B) for which appropriate credit support has been taken to alleviate the material credit risks of the counterparty thereto.

ARTICLE XI

The Agents

Section 11.01. Appointment; Powers.

(a) Each of the Lenders and the Issuing Bank hereby irrevocably appoints Citibank, N.A. to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Administrative Agent, the Lenders and the Issuing Bank, and neither the Borrower nor any other Loan Party shall have rights as a third-party beneficiary of any of such provisions. It is understood and agreed that the use of the term "agent" herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express)

104

obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

(b) The Administrative Agent shall also act as the "collateral agent" under the Loan Documents, and each of the Lenders (including in its capacities as a potential Swap Lender and/or Treasury Management Bank) and the Issuing Bank hereby irrevocably appoints and authorizes the Administrative Agent to act as the agent of such Lender and the Issuing Bank for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of the Loan Parties to secure any of the Obligations, together with such powers and discretion as are reasonably incidental thereto. In this connection, the Administrative Agent, as "collateral agent" and any co-agents, sub-agents and attorneys-in-fact appointed by the Administrative Agent pursuant to Section 11.05 for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Security Instruments, or for exercising any rights and remedies thereunder at the direction of the Administrative Agent, shall be entitled to the benefits of all provisions of this Article XI and Article XII (including Section 12.03(c), as though such co-agents, sub-agents and attorneys-in-fact were the "collateral agent" under the Loan Documents) as if set forth in full herein with respect thereto.

Section 11.02. Rights as a Lender. The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and the term "Lender" or "Lenders" shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for, and generally engage in any kind of business with, the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

Section 11.03. Exculpatory Provisions.

(a) The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent:

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

(ii) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents); provided that the Administrative Agent will not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan

105

Document or applicable law, including for the avoidance of doubt, any action that may be in violation of the automatic stay under any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law; and

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

(b) The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 12.02 and 10.02)), or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to the Administrative Agent in writing by the Borrower, a Lender or the Issuing Bank.

(c) The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, or the creation, perfection or priority of any Lien purported to be created by the Security Instruments, (v) the value or sufficiency of any of the Collateral, or (vi) the satisfaction of any condition set forth in Article VI or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

Section 11.04. Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance, extension, renewal or increase of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or the Issuing Bank, the Administrative Agent may presume that such condition is satisfactory to such Lender or the Issuing Bank unless the Administrative Agent shall have received notice to the contrary from such Lender or the Issuing Bank prior to the making of such Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower),

106

independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 11.05. Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub agents appointed by the Administrative Agent. The Administrative Agent and any such sub agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub agent and to the Related Parties of the Administrative Agent and any such sub agent, and shall apply to their respective activities in connection with the syndication of the Loans as well as activities as Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub agents.

Section 11.06. Resignation of Administrative Agent and/or Issuing Bank.

(a) The Administrative Agent may at any time give notice of its resignation to the Lenders, the Issuing Bank and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such 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, then the retiring Administrative Agent may on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent meeting the qualifications set forth above; provided that if the Administrative Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents and (2) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and the Issuing Bank directly, until such time as the Required Lenders appoint a successor Administrative Agent as provided for above in this Section. Upon the acceptance of a successor's appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this Section) . 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 retiring Administrative Agent's resignation hereunder and under the other Loan Documents, the provisions of this Article 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 the retiring Administrative Agent was acting as Administrative Agent.

107

(b) Any resignation by Citibank, N.A. as Administrative Agent pursuant to this Section shall also constitute its resignation as Issuing Bank. After the resignation of the Issuing Bank hereunder, the retiring Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement and the other Loan Documents with respect to Letters of Credit issued by it prior to such resignation, but shall not be required to issue additional Letters of Credit or to extend, renew or increase any existing Letter of Credit, including, without limitation, any Letter of Credit with an auto-extend feature (for the avoidance of doubt, the retiring Issuing Bank is authorized to notify any and each beneficiary of each Letter of Credit (in accordance with the terms of such Letter of Credit) that any such Letter of Credit will not be renewed, extended or increased, automatically or otherwise). Upon the acceptance of a successor's appointment as Administrative Agent hereunder, (i) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Issuing Bank, (ii) the retiring Issuing Bank and shall be discharged from all of their respective duties and obligations hereunder or under the other Loan Documents, and (iii) the successor Issuing Bank shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to the retiring Issuing Bank to effectively assume the obligations of the retiring Issuing Bank with respect to such Letters of Credit.

(c) In addition to the foregoing, if a Lender becomes, and during the period it remains, a Defaulting Lender or a Potential Defaulting Lender, the Issuing Bank may, upon prior written notice to the Borrower and the Administrative Agent, resign as Issuing Bank, effective at the close of business New York time on a date specified in such notice (which date may not be less than 30 days after the date of such notice); provided that such resignation by the Issuing Bank will have no effect on the validity or enforceability of any Letter of Credit then outstanding or on the obligations of the Borrower or any Lender under this Agreement with respect to any such outstanding Letter of Credit or otherwise to the Issuing Bank.

Section 11.07. Non-Reliance on Administrative Agent and Other Lenders. Each Lender and the Issuing Bank acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender and the Issuing Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties 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 or any related agreement or any document furnished hereunder or thereunder.

Section 11.08. No Other Duties, etc. Anything herein to the contrary notwithstanding, none of the Bookrunners, Arrangers, Documentation Agents or Syndication Agents listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent, a Lender or the Issuing Bank hereunder. No Bookrunner, Arranger, Documentation Agent or Syndication Agent listed on the cover page hereof shall have or be deemed to have any fiduciary relationship with any Lender.

Section 11.09. Administrative Agent May File Proofs of Claim. In case of the pendency of any proceeding under any Debtor Relief Law or any other judicial proceeding relative to any Loan Party, the Administrative Agent (irrespective of whether the principal of any Loan or LC Exposure shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered (but not obligated) by intervention in such proceeding or otherwise:

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, LC Exposure and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the Issuing Bank and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the Issuing Bank and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the Issuing Bank and the Administrative Agent under Sections 3.05 and 12.03) allowed in such judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender and the Issuing Bank to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders and the Issuing Bank, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Section 12.03.

Section 11.10. Collateral and Guaranty Matters.

(a) Each of Lenders and the other Secured Parties (including each Lender in its capacity as a potential Swap Lender and/or Treasury Management Bank), and the Issuing Bank, irrevocably authorize the Administrative Agent, at its option and in its discretion,

(i) to release any Lien on any property granted to or held by the Administrative Agent under any Loan Document (x) upon termination of all of the Aggregate Commitments and payment in full of all Obligations (other than contingent indemnification obligations) and the expiration or termination of all Letters of Credit (other than Letters of Credit as to which other arrangements satisfactory to the Administrative Agent and the Issuing Bank shall have been made), (y) that is sold or otherwise disposed of or to be sold or otherwise disposed of as part of or in connection with any sale or other disposition permitted under the Loan Documents, or (z) subject to Section 12.02, if approved, authorized or ratified in writing by the Required Lenders;

(ii) to subordinate any Lien on any property granted to or held by the Administrative Agent under any Loan Document to the holder of any Lien on such property that is permitted by Section 9.03; and

109

(iii) to release any Guarantor from its obligations under the Guaranty Agreement if such Person ceases to be a Subsidiary as a result of a transaction permitted under the Loan Documents.

Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent's authority to release or subordinate its interest in particular types or items of property, or to release any Guarantor from its obligations under the Guaranty Agreement pursuant to this Article XI. In each case as specified in this Section 11.10, the Administrative Agent will, at the Borrower's expense, execute and deliver to the applicable Loan Party such documents as such Loan Party may reasonably request to evidence the release of such item of Collateral from the assignment and security interest granted under the Security Instruments or to subordinate its interest in such item, or to release such Guarantor from its obligations under the Guaranty Agreement, in each case in accordance with the terms of the Loan Documents and this Section 11.10.

(b) The Administrative Agent shall not be responsible for or have a duty to ascertain or inquire into any representation or warranty regarding the existence, value or collectability of the Collateral, the existence, priority or perfection of the Administrative Agent's Lien thereon, or any certificate prepared by any Loan Party in connection therewith, nor shall the Administrative Agent be responsible or liable to the Lenders for any failure to monitor or maintain any portion of the Collateral.

Section 11.11. Secured Swap Agreements and Secured Treasury Management Agreements. No Swap Lender or Treasury Management Bank that obtains the benefits of Section 10.02(c), any Guaranty Agreement or any Collateral by virtue of the provisions hereof or of any Guaranty Agreement or any Security Instrument shall have any right to notice of any action or to consent to, direct or object to any action hereunder or under any other Loan Document or otherwise in respect of the Collateral (including the release or impairment of any Collateral) other than in its capacity as a Lender and, in such case, only to the extent expressly provided in the Loan Documents. Notwithstanding any other provision of this Article XI to the contrary, the Administrative Agent shall not be required to verify the payment of, or that other satisfactory arrangements have been made with respect to, Obligations arising under Secured Swap Agreements and/or Secured Treasury Management Agreements unless the Administrative Agent has received written notice of such Obligations, together with such supporting documentation as the Administrative Agent may request, from the applicable Swap Lender or Treasury Management Bank, as the case may be.

Notices sent by hand or overnight courier service, or mailed by certified or registered mail, shall be deemed to have been given when received; notices sent by telecopier shall be deemed to have been given when sent (except that, if not given during normal business hours for the recipient, shall be deemed to have been given at the opening of business on the next Business Day for the recipient). Notices delivered through electronic communications to the extent provided in paragraph (b) below, shall be effective as provided in said paragraph (b).

(b) Notices and other communications to the Lenders and the Issuing Bank hereunder may be delivered or furnished by electronic communication (including e-mail and Internet or intranet websites) pursuant to procedures approved by the Administrative Agent; provided that the foregoing shall not apply to any Lender or the Issuing Bank pursuant to ARTICLE II, ARTICLE III, ARTICLE IV and ARTICLE V if such Lender or the Issuing Bank, as applicable, has notified the Administrative Agent that it is incapable of receiving notices under such Article by electronic communication. The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by

111

electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be limited to particular notices or communications.

Unless the Administrative Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address shall be deemed received upon the sender's receipt of an acknowledgement from the intended recipient (such as by the "return receipt requested" function, as available, return e-mail or other written acknowledgement), and (ii) notices or communications posted to an Internet or intranet website shall be deemed received upon the deemed receipt by the intended recipient at its e-mail address as described in the foregoing clause (i) of notification that such notice or communication is available and identifying the website address therefor; provided that for both clauses (i) and (ii) above, if such notice or other communication is not sent during the normal business hours of the recipient, such notice or communication shall be deemed to have been sent at the opening of business on the next business day for the recipient.

(c) Any party hereto may change its address or facsimile number for notices and other communications hereunder by notice to the other parties hereto.

(d) Platform.

(i) Each Loan Party agrees that the Administrative Agent and/or the Arrangers may, but shall not be obligated to, make the Communications (as defined below) available to the Issuing Bank and the other Lenders by posting the Communications on Debt Domain, Intralinks, Syndtrak or a substantially similar electronic transmission system (the "Platform").

(ii) The Platform is provided "as is" and "as available." The Agent Parties (as defined below) do not warrant the adequacy of the Platform and expressly disclaim liability for errors or omissions in the Communications. No warranty of any kind, express, implied or statutory, including, without limitation, any warranty of merchantability, fitness for a particular purpose, non-infringement of third-party rights or freedom from viruses or other code defects, is made by any Agent Party in connection with the Communications or the Platform. In no event shall the Administrative Agent or any of its Related Parties (collectively, the "Agent Parties") have any liability to the Borrower or the other Loan Parties, any Lender or any other Person or entity for damages of any kind, including, without limitation, direct or indirect, special, incidental or consequential damages, losses or expenses (whether in tort, contract or otherwise) arising out of the Borrower's, any Loan Party's or the Administrative Agent's transmission of communications through the Platform. "Communications" means, collectively, any notice, demand, communication, information, document or other material provided by or on behalf of the Borrower, any Loan Party nor Parent pursuant to any Loan Document or the transactions contemplated therein which is distributed to the Administrative Agent, any Lender or the Issuing Bank by means of electronic communications, including through the Platform.

(iii) Each Public Lender agrees to cause at least one individual at or on behalf of such Public Lender to at all times have selected the "Private Side Information" or similar designation on the content declaration screen of the Platform in order to enable such Public Lender or its delegate, in accordance with such Public Lender's compliance procedures

112

and applicable Law, including United States Federal and state securities Laws, to make reference to Communications that are not made available through the "Public Side Information" portion of the Platform and that may contain material non-public information with respect to the Borrower, any of the other Loan Parties, or Parent, or their securities for purposes of United States Federal or state securities laws.

Section 12.02. Waivers; Amendments.

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

Notwithstanding anything to the contrary contained herein or in any other Loan Document, the authority to enforce rights and remedies hereunder and under the other Loan Documents against the Loan Parties or any of them shall be vested exclusively in, and all actions and proceedings at law in connection with such enforcement shall be instituted and maintained exclusively by, the Administrative Agent in accordance with Section 10.02 for the benefit of all the Lenders and the Issuing Bank; provided, however, that the foregoing shall not prohibit (a) the Administrative Agent from exercising on its own behalf the rights and remedies that inure to its benefit (solely in its capacity as the Administrative Agent) hereunder and under the other Loan Documents, (b) the Issuing Bank from exercising the rights and remedies that inure to its benefit (solely in its capacity as Issuing Bank) hereunder and under the other Loan Documents, (c) any Lender from exercising setoff rights in accordance with Section 12.08 (subject to the terms of Section 4.01), or (d) any Lender from filing proofs of claim or appearing and filing pleadings on its own behalf during the pendency of a proceeding relative to any Loan Party under any debtor relief law; and provided, further, that if at any time there is no Person acting as the Administrative Agent hereunder and under the other Loan Documents, then (i) the Required Lenders shall have the rights otherwise ascribed to the Administrative Agent pursuant to Section 10.02 and (ii) in addition to the matters set forth in clauses (b), (c) and (d) of the preceding proviso and subject to Section 4.01, any Lender may, with the consent of the Required Lenders, enforce any rights and remedies available to it and as authorized by the Required Lenders.

113

(b) Neither this Agreement nor any provision hereof nor any other Loan Document 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 or the Maximum Credit Amount of any Lender without the written consent of such Lender, (ii) increase the Borrowing Base without the written consent of the Borrowing Base Increase Requisite Lenders, decrease or maintain the Borrowing Base without the consent of the Required Lenders, or modify Section 2.07 in any manner without the consent of each Lender affected thereby, (iii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, or reduce any other Obligations hereunder or under any other Loan Document, without the written consent of each Lender affected thereby, (iv) postpone the scheduled date of payment or prepayment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or any other Obligations hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Termination Date without the written consent of each Lender affected thereby, (v) change Section 2.02(a), Section 2.04(a), Section 2.06(b)(ii), Section 3.04(b), Section 4.01(b), Section 4.01(c) or Section 10.02(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender affected thereby, (vi) waive or amend Section 8.14, without the written consent of each Lender affected thereby, (vii) release all or substantially all of the Guarantors (except in accordance with the terms of the Guaranty Agreement), release all or substantially all of the Collateral (other than as provided in Section 11.10), or reduce the percentage set forth in Section 8.14(a) to less than 80%, without the written consent of each Lender affected thereby, or (viii) change any of the provisions of this Section 12.02(b) or the definition of "Determining Lenders", "Required Lenders", "Borrowing Base Increase Requisite 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 affected thereby; provided further that notwithstanding the foregoing or any other provision to the contrary, (A) no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, any other Agent, or the Issuing Bank hereunder or under any other Loan Document without the prior written consent of the Administrative Agent, such other Agent or the Issuing Bank, as the case may be, and (B) nothing in this Section 12.02 shall cause any waiver, amendment, modification or consent to (I) any fee letter between the Borrower and any Lender, Agent or the Administrative Agent or the Issuing Bank to require the consent of the Required Lenders, (II) any Letter of Credit Agreements between the Borrower or any Subsidiary of the Borrower and the Issuing Bank to require the consent of the Required Lenders, (III) any Letter of Credit issued by the Issuing Bank pursuant to the terms of this Agreement to require the consent of the Required Lenders except as specifically required by Section 2.08, (IV) any Secured Swap Agreement to require the consent of the Required Lenders, or (V) any Secured Treasury Management Agreement to require the consent of the Required Lenders.

(c) Anything herein to the contrary notwithstanding, during such period as a Lender is a Defaulting Lender, to the fullest extent permitted by applicable law, such Lender will not be entitled to vote in respect of amendments and waivers hereunder and the Commitment and the outstanding Loans or other extensions of credit of such Lender hereunder will not be taken

114

into account in determining whether the Required Lenders, the Borrowing Base Increase Requisite Lenders or all of the Lenders, as required, have approved any such amendment or waiver (and the definition of "Required Lenders" and "Borrowing Base Increase Requisite Lenders" will automatically be deemed modified accordingly for the duration of such period); provided, that any such amendment or waiver that would increase or extend the term of the Commitment of such Defaulting Lender, extend the date fixed for the payment of principal or interest owing to such Defaulting Lender hereunder, reduce the principal amount of any obligation owing to such Defaulting Lender, reduce the amount of or the rate or amount of interest on any amount owing to such Defaulting Lender or of any fee payable to such Defaulting Lender hereunder, or alter the terms of this proviso, will require the consent of such Defaulting Lender.

Section 12.03. Expenses, Indemnity; Damage Waiver.

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

(b) THE BORROWER SHALL INDEMNIFY THE ADMINISTRATIVE AGENT (AND ANY SUB-AGENT THEREOF), EACH LENDER AND THE ISSUING BANK, 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, PENALTIES AND RELATED EXPENSES (INCLUDING THE FEES, CHARGES AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE), AND SHALL INDEMNIFY AND HOLD HARMLESS EACH INDEMNITEE FROM ALL FEES AND TIME CHARGES AND DISBURSEMENTS FOR ATTORNEYS WHO MAY BE

115

EMPLOYEES OF ANY INDEMNITEE, INCURRED BY ANY INDEMNITEE OR ASSERTED AGAINST ANY INDEMNITEE BY ANY PERSON OR BY THE BORROWER OR ANY OTHER LOAN PARTY ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF (I) THE EXECUTION OR DELIVERY OF THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY OR THEREBY, THE PERFORMANCE BY THE PARTIES HERETO OF THEIR RESPECTIVE OBLIGATIONS HEREUNDER OR THEREUNDER OR THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, (II) ANY LOAN OR LETTER OF CREDIT OR THE USE OR PROPOSED USE OF THE PROCEEDS THEREFROM (INCLUDING ANY REFUSAL BY THE ISSUING BANK TO HONOR A DEMAND FOR PAYMENT UNDER A LETTER OF CREDIT IF THE DOCUMENTS PRESENTED IN CONNECTION WITH SUCH DEMAND DO NOT STRICTLY COMPLY WITH THE TERMS OF SUCH LETTER OF CREDIT), (III) ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF HAZARDOUS MATERIALS ON OR FROM ANY PROPERTY OWNED OR OPERATED BY THE BORROWER OR ANY OF THE SUBSIDIARIES OR OTHER LOAN PARTIES, OR ANY ENVIRONMENTAL LIABILITY RELATED IN ANY WAY TO THE BORROWER OR ANY OF THE SUBSIDIARIES OR OTHER LOAN PARTIES, OR (IV) ANY ACTUAL OR PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY, WHETHER BROUGHT BY A THIRD PARTY OR BY THE BORROWER OR ANY SUBSIDIARY OR OTHER LOAN PARTY, AND REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO, PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES, PENALTIES OR RELATED EXPENSES (X) 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 OR (Y) RESULT FROM A CLAIM BROUGHT BY THE BORROWER OR ANY OTHER LOAN PARTY AGAINST AN INDEMNITEE FOR MATERIAL BREACH IN BAD FAITH OF SUCH INDEMNITEE'S OBLIGATIONS HEREUNDER OR UNDER ANY OTHER LOAN DOCUMENT, IF THE BORROWER OR SUCH LOAN PARTY HAS OBTAINED A FINAL AND NONAPPEALABLE JUDGMENT IN ITS FAVOR ON SUCH CLAIM AS DETERMINED BY A COURT OF COMPETENT JURISDICTION. This Section 12.03(b) shall not apply with respect to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim.

(c) To the extent that the Borrower for any reason fails to indefeasibly pay any amount required under paragraph (a) or (b) of this Section to be paid by it to the Administrative Agent (or any sub-agent thereof), the Issuing Bank or any Related Party of any of the foregoing, each Lender severally agrees to pay to the Administrative Agent (or any such sub-agent), the Issuing Bank or such Related Party, as the case may be, such Lender's pro rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought based on each Lender's Total Credit Exposure at such time) of such unpaid amount (including any such unpaid amount in respect of a claim asserted by such Lender); provided that with respect to such unpaid amounts owed to the Issuing Bank solely in its capacity as such, only the Lenders shall be required to pay such unpaid amounts, such payment to be made severally

116

among them based on such Lenders' Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) provided, further, that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent (or any such sub-agent), the Issuing Bank in its capacity as such, or against any Related Party of any of the foregoing acting for the Administrative Agent (or any such sub-agent), the Issuing Bank in connection with such capacity. The obligations of the Lenders under this paragraph (c) are subject to the provisions of Section 2.05(c).

(d) To the fullest extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof. No Indemnitee referred to in paragraph (b) above shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby.

(e) All amounts due under this Section 12.03 shall be payable not later than three Business Days after written demand therefor.

(f) The provisions of this Section 12.03 shall remain operative and in full force and effect regardless of the expiration of the term of this Agreement, the consummation of the transactions contemplated hereby, the repayment of any of the Loans and the Obligations, the expiration or termination of the Aggregate Commitments, the expiration of any Letter of Credit, the invalidity, unenforceability or termination of any or all Loan Documents or term or provision of this Agreement or any other Loan Document, or any investigation made by or on behalf of the Administrative Agent, any Lender or the Issuing Bank.

Section 12.04. Successors and Assigns Generally.

(a) Successors and Assigns Generally. 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 neither the Borrower nor any other Loan Party may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender, and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section, or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). 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 paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related

117

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) Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender's Commitment and/or the Loans at the time owing to it or contemporaneous assignments to related Approved Funds that equal at least the amount specified in paragraph (b)(i)(B) of this Section in the aggregate or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B) in any case not described in paragraph (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance 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 or, if "Trade Date" is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000, unless each of the Administrative Agent and, so long as no Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed).

(ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender's rights and obligations under this Agreement with respect to the Loan or the Commitment assigned.

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by paragraph (b)(i)(B) of this Section and, in addition:

(A) the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) a Default has occurred and is continuing at the time of such assignment, or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided 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 notice thereof and provided, further, that the Borrower's consent shall not be required during the primary syndication of the Loans for this Third Amended and Restated Credit Agreement;

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments if such assignment is to a Person that is not a Lender with a Commitment, an Affiliate of such Lender or an Approved Fund with respect to such Lender;

118

and

(C) the consent of the Issuing Bank shall be required for any assignment in respect of the Loan and Commitment of any Lender.

(iv) Assignment and Assumption. 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; provided that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment. The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(v) No Assignment to Certain Persons. No such assignment shall be made to (A) any Loan Party or any Loan Party's Affiliates and Subsidiaries or (B) any Defaulting Lender or Potential Defaulting Lender or any of their respective subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B).

(vi) No Assignment to Natural Persons. No such assignment shall be made to a natural Person.

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

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement 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

119

hereto) but shall continue to be entitled to the benefits of Sections 5.01 and 5.03 and Section 12.03 with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender's having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section.

(c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at its office located at ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the "Register"), and upon the determination by the Administrative Agent of (i) the satisfaction of all conditions precedent to the effectiveness of such Assignment and Assumption (including, without limitation, the receipt of all requisite consents, payment of fees and transfer of money) and (ii) the expiration of any trading freeze or trading holds due to any amendment, consent or waiver, or any other interruption in, or hold on, trading as determined by the Administrative Agent, the Administrative Agent will accept such Assignment and Assumption and record the appropriate information contained therein in the Register. The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent and the Lenders shall 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. 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.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural Person or the Borrower or any of the Borrower's Affiliates or Subsidiaries) (each, a "Participant") in all or a portion of such Lender's rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender's obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and (iii) the Borrower, the Administrative Agent, the Issuing Bank and Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 2.08(c), Section 12.03(c) and otherwise with respect to any payments made by such Lender to its Participant(s).

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 which requires the consent of each Lender affected thereby under Section 12.02 to the extent if affects such

120

Participant. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 5.01, 5.02 and 5.03 (subject to the requirements and limitations therein, including the requirements under Section 5.03(g) (it being understood that the documentation required under Section 5.03(g) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Sections 5.04 and 12.18 as if it were an assignee under paragraph (b) of this Section; and (B) shall not be entitled to receive any greater payment under Sections 5.01 or 5.03, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower's request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 12.18 with respect to any Participant. To the extent permitted by law, each Participant shall also be entitled to the benefits of Section 12.08 as though it were a Lender; provided that such Participant agrees to be subject to Section 4.01 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant's interest in the Loans or other obligations under the Loan Documents (the "Participant Register"); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant's interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(e) Certain Pledges. 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; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

Section 12.05. Survival; Revival; Reinstatement.

(a) All covenants, agreements, representations and warranties made by the Borrower and the other Loan Parties herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, any other Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the

121

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 Obligation or amount payable under this Agreement or any other Loan Document is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Aggregate Commitments have not expired or terminated. The provisions of Section 5.01, Section 5.02, Section 5.03 and Section 12.03 and ARTICLE XI shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans or any other Obligation, the expiration or termination of the Letters of Credit and the Aggregate Commitments or the termination of this Agreement, any other Loan Document or any provision hereof or thereof.

(b) To the extent that any payments on the 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 and the Lenders to effect such reinstatement.

Section 12.06. Counterparts; Integration; Effectiveness; Electronic Signatures.

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

(b) This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof and thereof. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES HERETO AND THERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

(c) Except as provided in Section 6.02, 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 facsimile shall be effective as delivery of a manually executed counterpart of this Agreement.

122

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

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, the Issuing Bank, and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held, and other obligations (in whatever currency) at any time owing, by such Lender, the Issuing Bank or any such Affiliate, to or for the credit or the account of the Borrower or any other Loan Party against any and all of the obligations of the Borrower or such Loan Party now or hereafter existing under this Agreement or any other Loan Document to such Lender or the Issuing Bank or their respective Affiliates, irrespective of whether or not such Lender, the Issuing Bank or Affiliate shall have made any demand under this Agreement or any other Loan Document and although such obligations of the Borrower or such Loan Party may be contingent or unmatured or are owed to a branch, office or Affiliate of such Lender or the Issuing Bank different from the branch, office or Affiliate holding such deposit or obligated on such indebtedness; provided that in the event that any Defaulting Lender exercises any such right of setoff, (x) all amounts so set off will be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.13(a)(i) and, pending such payment, will be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent, the Issuing Bank and the Lenders and (y) the Defaulting Lender will provide promptly to the Administrative Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of each Lender, the Issuing Bank and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender, the Issuing Bank or their respective Affiliates may have. Each Lender and the Issuing Bank agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application; provided that the failure to give such notice shall not affect the validity of such setoff and application.

(b) Submission to Jurisdiction. The Borrower and each other Loan Party irrevocably and unconditionally agrees that it will not commence any action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, against the Administrative Agent, any Lender, the Issuing Bank, or any Related Party of the foregoing in any way relating to this Agreement or any other Loan Document or the transactions relating hereto or thereto, in any forum other than the courts 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 in the Borough of Manhattan, and any appellate court from any thereof, and each of the parties hereto irrevocably and unconditionally submits to the jurisdiction of such courts and agrees that all claims in respect of any such action, litigation or proceeding may be heard and determined in such New York State court or, to the fullest extent permitted by applicable law, in such federal court. Each of the parties hereto agrees that a final judgment in any such action, litigation or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or in any other Loan Document shall affect any right that the Administrative Agent, any Lender or the Issuing Bank may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against the Borrower or any other Loan Party or its properties in the courts of any jurisdiction.

(c) Waiver of Venue. The Borrower and each other Loan Party irrevocably and unconditionally waives, to the fullest extent permitted by applicable law, any objection that it may now or hereafter have to the laying of venue of any action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in paragraph (b) of this Section.

124

TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

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, the Issuing Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its Related Parties (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 required or requested by any regulatory authority purporting to have jurisdiction over such Person or its Related Parties (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement or any other Loan Document, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section 12.11, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights and obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any Swap Agreement or any of its Related Parties relating to the Borrower, any other Loan Party and their obligations, (g) with the consent of the Borrower, (h) to any credit insurance provider relating to the Borrower and its obligations, this Agreement or payments hereunder, (i) on a confidential basis (i) to any rating agency in connection with the rating the Parent, the Borrower or the Subsidiaries or the Loans or (ii) the CUSIP Service Bureau or any similar agency in connection with the issuance and monitoring of CUSIP numbers with respect to the Loans; or (j) to the extent such Information (1) becomes publicly available other than as a result of a breach of this Section 12.11 or (2) becomes available to the Administrative Agent, the Issuing Bank or any Lender or any of their Affiliates 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, the Parent or any of the Subsidiaries relating to the Parent, the Borrower or any of the Subsidiaries and their respective businesses, other than any such information that is available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Parent, the Borrower or any of the Subsidiaries; provided that, in the case of information received from the Parent, the Borrower or any Subsidiary after the date

125

hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section 12.11 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

Each of the Administrative Agent, the Lenders and the Issuing Bank acknowledges that (a) the Information may include material non-public information concerning the Parent, the Borrower or a Subsidiary, as the case may be, (b) it has developed compliance procedures regarding the use of material non-public information and (c) it will handle such material non-public information in accordance with applicable Law, including United States Federal and state securities Laws.

Section 12.12. Interest Rate Limitation. It is the intention of the parties hereto that each Lender shall conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be usurious as to any Lender under laws applicable to it (including the laws of the United States of America and the States of New York and Texas, or any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any of the Loan Documents or any agreement entered into in connection with or as security for the Obligations, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under law applicable to any Lender that is contracted for, taken, reserved, charged or received by such Lender under any of the Loan Documents or agreements or otherwise in connection with the Loans shall under no circumstances exceed the maximum amount allowed by such applicable law, and any excess shall be canceled automatically and if theretofore paid shall be credited by such Lender on the principal amount of the Obligations (or, to the extent that the principal amount of the Obligations shall have been or would thereby be paid in full, refunded by such Lender to the Borrower); and (ii) in the event that the maturity of the Loans is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Lender may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of the Obligations (or, to the extent that the principal amount of the Obligations shall have been or would thereby be paid in full, refunded by such Lender to the Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated and spread throughout the stated term of the Loans until payment in full so that the rate or amount of interest on account of any Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at any time and from time to time (i) the amount of interest payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to such Lender pursuant to this Section 12.12 and (ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to such Lender would be less than the amount of interest payable to such Lender computed at the Highest Lawful Rate applicable to such Lender, then the amount of interest payable to such Lender in respect of such subsequent interest computation period shall continue to be computed

126

at the Highest Lawful Rate applicable to such Lender until the total amount of interest payable to such Lender shall equal the total amount of interest which would have been payable to such Lender if the total amount of interest had been computed without giving effect to this Section 12.12. To the extent that Chapter 303 of the Texas Finance Code is relevant for the purpose of determining the Highest Lawful Rate applicable to a Lender, such Lender elects to determine the applicable rate ceiling under such Chapter by the weekly ceiling from time to time in effect. Chapter 346 of the Texas Finance Code does not apply to the Borrower's obligations hereunder.

Section 12.13. EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT "CONSPICUOUS."

Section 12.14. Collateral Matters; Swap Agreements; Treasury Management Agreements. The benefit of the Security Instruments and of the provisions of this Agreement relating to any Collateral securing the Obligations shall also extend to and be available to (a) any Swap Lender with respect to amounts payable by the Borrower, any Subsidiary, and any Guarantor under any Secured Swap Agreement, and (b) any Treasury Management Bank with respect to amounts payable by the Borrower, any Subsidiary, and any Guarantor under any Secured Treasury Management Agreement, in each case on a pari passu basis with respect to repayment of principal outstanding on Loans due under this Agreement. All Secured Swap Agreements and Secured Treasury Management Agreements are independent agreements governed by the terms thereof and will remain in full force and effect, unaffected by any repayment, prepayment, acceleration, reduction, increase or change in the terms of the Loans created under this Agreement except as otherwise provided in such Secured Swap Agreements and Secured Treasury Management Agreements, and any payoff statement from any Lender relating to this Agreement shall not apply to Secured Swap Agreements and Secured Treasury Management Agreements, except as otherwise expressly provided in such payoff statement.

127

Section 12.15. No Third Party Beneficiaries. This Agreement, the other Loan Documents, and the agreement of the Lenders to make Loans and the Issuing Bank to issue, amend, renew or extend Letters of Credit hereunder are solely for the benefit of the Borrower, and no other Person (including, without limitation, the Parent, any Subsidiary, any obligor, contractor, subcontractor, supplier or materialman) shall have any rights, claims, remedies or privileges hereunder or under any other Loan Document against the Administrative Agent, any other Agent, the Issuing Bank or any Lender for any reason whatsoever. There are no third party beneficiaries.

Section 12.16. USA Patriot Act Notice. Each Lender that is subject to the Act (as hereinafter defined) and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the "Act"), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Act.

Section 12.17. Amendment and Restatement; Release. This Agreement amends and restates in its entirety the Original 2009 Credit Agreement, which, in turn, amended and restated in its entirety the Original 2008 Credit Agreement, which, in turn, amended and restated in its entirety the Original 2007 Credit Agreement. The execution of this Agreement and the other Loan Documents executed in connection herewith does not extinguish the Obligations outstanding in connection with the Original 2009 Credit Agreement nor does it constitute a novation with respect to such indebtedness. THE BORROWER REPRESENTS AND WARRANTS THAT AS OF THE DATE HEREOF THERE ARE NO CLAIMS OR OFFSETS AGAINST OR DEFENSES OR COUNTERCLAIMS TO ITS OR ANY GUARANTORS OBLIGATIONS UNDER THE ORIGINAL 2009 CREDIT AGREEMENT OR THE OTHER LOAN DOCUMENTS. TO INDUCE THE ADMINISTRATIVE AGENT AND THE LENDERS TO ENTER INTO THIS AGREEMENT, THE BORROWER AND, BY THE EXECUTION OF THE LOAN DOCUMENTS TO WHICH IT IS A PARTY, EACH GUARANTOR WAIVES ANY AND ALL CLAIMS, OFFSETS, DEFENSES OR COUNTERCLAIMS, WHETHER KNOWN OR UNKNOWN, ARISING PRIOR TO THE DATE HEREOF AND HEREBY RELEASES THE ADMINISTRATIVE AGENT, THE LENDERS, AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS AND ATTORNEYS (COLLECTIVELY, THE "RELEASED PARTIES") FROM ANY AND ALL OBLIGATIONS, INDEBTEDNESS, LIABILITY, CLAIMS, RIGHTS, CAUSES OF ACTION OR DEMANDS WHATSOEVER, WHETHER KNOWN OR UNKNOWN, SUSPECTED OR UNSUSPECTED WHICH BORROWER OR ANY GUARANTOR EVER HAD, NOW HAS, CLAIMS TO HAVE OR MAY HAVE AGAINST ANY RELEASED PARTY ARISING PRIOR TO THE DATE HEREOF OR FROM OR IN CONNECTION WITH THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY.

Section 12.18. Replacement of Lenders. If any Lender requests compensation under Section 5.01, or if the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03 and, in each case, such Lender has declined or is unable to designate a different

128

lending office in accordance with Section 5.04(a), or if any Lender is a Defaulting Lender, a Dissenting Lender or a Non-Consenting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 12.04), all of its interests, rights (other than its existing rights to payments pursuant to Section 5.01 or Section 5.03) and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that:

(a) the Borrower shall have paid to the Administrative Agent the assignment fee (if any) specified in Section 12.04;

(b) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 5.02) 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);

(c) 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 thereafter;

(d) such assignment does not conflict with applicable law; and

(e) in the case of any assignment resulting from a Lender becoming a Non-Consenting Lender, the applicable assignee shall have consented to the applicable amendment, waiver or consent.

A Lender shall not be required to make any such assignment or 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 12.19. Time of the Essence. Time is of the essence of the Loan Documents.

Section 12.20. No Advisory or Fiduciary Responsibility. The Borrower and each other Loan Party acknowledges and agrees, and acknowledges its Affiliates' understanding, that in connection with all aspects of (1) the transaction evidenced by this Agreement and the other Loan Documents, (2) the Transactions and (3) each other transaction contemplated hereby and by the other Loan Documents (including in connection with any amendment, waiver or other modification hereof or of any other Loan Document) that:

(a)

(i) the arranging and other services regarding this Agreement and the other Loan Documents provided by the Agents and the Arrangers, are arm's-length commercial transactions between the Borrower, each other Loan Party and their respective Affiliates, on the

129

(ii) each of the Borrower and the other Loan Parties has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate, and

(iii) the Borrower and each other Loan Party is capable of evaluating, and understands and accepts, the terms, risks and conditions of the transactions contemplated hereby and by the other Loan Documents;

(b)

(ii) none of the Administrative Agent, the other Agents nor any of the Arrangers has any obligation to the Borrower, any other Loan Party or any of their respective Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other Loan Documents;

(iii) any of the Administrative Agent, the other Agents and the Arrangers, and any of their respective Affiliates, may be engaged in a broad range of transactions that involve interests that differ from those of the Borrower, the other Loan Parties and their respective Affiliates, and none of the Administrative Agent, the other Agents nor any of the Arrangers has any obligation to disclose any of such interests to the Borrower, any other Loan Party or any of their respective Affiliates.

To the fullest extent permitted by law, each of the Borrower and the other Loan Parties hereby waives and releases any claims that it may have against the Administrative Agent, any of the other Agents or any of the Arrangers with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby and by the other Loan Documents.

Section 12.21. The Parent. It is specifically agreed among the parties hereto that the Parent will be a co-issuer of the Senior Notes but otherwise act solely as a holding company for the Equity Interests of the Borrower and certain of the Subsidiaries.
