Unless the context requires otherwise (a) any definition of or reference to any agreement, instrument or other document herein shall be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth in the Loan Documents), (b) any reference herein to any law shall be construed as referring to such law as amended, modified, codified or reenacted, in whole or in part, and in effect from time to time, (c) any reference herein to any Person shall be construed to include such Person’s successors and assigns (subject to the restrictions contained in the Loan Documents), (d) the words “herein”, “hereof” and “hereunder”, and words of similar import, shall be construed to refer to this Agreement in its entirety and not to any particular provision hereof, (e) with respect to the determination of any time period, the word “from” means “from and including” and the word “to” means “to and including” and (f) any reference herein to Articles, Sections, Annexes, Exhibits and Schedules shall be construed to refer to Articles and Sections of, and Annexes, Exhibits and Schedules to, this Agreement.

Section 1.05 Accounting Terms and Determinations; GAAP. Unless otherwise specified herein, all accounting terms used herein shall be interpreted, all determinations with respect to accounting matters hereunder shall be made, and all financial statements and certificates and reports as to financial matters required to be furnished to the Administrative Agent or the Lenders hereunder shall be prepared, in accordance with GAAP, applied on a basis consistent with the Financial Statements except for changes in which Borrower’s independent certified public accountants concur and which are disclosed in such Financial Statements or to the Administrative Agent on the next date on which financial statements are required to be delivered to the Lenders pursuant to Section 8.01(a); provided that, if (i) the Borrower notifies the Administrative Agent that the Borrower requests an amendment to any provision hereof to eliminate the effect of any change occurring after the date hereof in GAAP or in the application thereof on the operation of or calculation of compliance with such provision or (ii) the Administrative Agent notifies the Borrower that the Majority Lenders request an amendment to any provision hereof for such purpose, regardless of whether any such notice is given before or after such change in GAAP or in the application thereof, then such provision shall be interpreted on the basis of GAAP as in effect and applied immediately before such change shall have become effective until such notice shall have been withdrawn

or such provision amended in accordance herewith. Notwithstanding anything herein to the contrary, for the purposes of calculating any of the ratios tested under Section 9.01, and the components of each of such ratios, the following shall be excluded: all Unrestricted Subsidiaries, and their Subsidiaries (including their assets, liabilities, income, expenses, losses, cash flows, and the elements thereof), except as set forth in clause (a) of the definition of Consolidated Net Income.

ARTICLE 2
The Credits

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

Section 2.02 Loans and Borrowings. (a) Borrowings; Several Obligations. Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance with their respective Commitments. Any Swingline Loan shall be made in accordance with the procedures set forth in Section 2.10. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments are several and no Lender shall be responsible for any other Lender’s failure to make Loans as required.

(b) Types of Loans. Subject to Section 3.03, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may request in accordance herewith. Each Swingline Borrowing shall be comprised entirely of ABR Loans as the Borrower may request in accordance with Section 2.10. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement. No such designation or transfer shall result in any liability on the part of the Borrower for increased costs or expenses resulting solely from such designation or transfer (except any such transfer which is made by a Lender pursuant to Section 5.04 or Section 5.05, or otherwise for the purpose of complying with any Governmental Requirement). Increased costs for expenses resulting from a Change in Law occurring subsequent to any such designation or transfer shall be deemed not to result solely from such designation or transfer.

(c) Minimum Amounts; Limitation on Number of Borrowings. Each Eurodollar Borrowing shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than $3,000,000. Each ABR Borrowing shall be in an aggregate amount that is an integral multiple of $100,000 and not less than $500,000; provided that an ABR Borrowing may be in an aggregate amount that is equal to the entire unused balance of the total Commitments or that is required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.08(e). Borrowings of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of 10 Eurodollar Borrowings outstanding. Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

(d) Notes. If requested by a Lender, the Loans made by such Lender shall be evidenced by a single promissory note of the Borrower in substantially the form of Exhibit A, dated, in the case of (i) any Lender party hereto as of the date of this Agreement, as of the Effective Date, and (ii) any other Lender, as of the date such Lender becomes a party hereto, payable to such Lender in a principal amount equal to its

Maximum Credit Amount as in effect on such date, and otherwise duly completed. In the event that any Lender’s Maximum Credit Amount increases or decreases for any reason (whether pursuant to Section 2.06, Section 2.09, Section 12.04(b) or otherwise), the Borrower shall deliver or cause to be delivered, to the extent such Lender is then holding a Note and upon the written request of such Lender, on the effective date of such increase or decrease, a new Note payable to such Lender in a principal amount equal to its Maximum Credit Amount after giving effect to such increase or decrease, and otherwise duly completed. Upon receipt of such replacement Note, such Lender shall return the replaced Note to the Borrower. The date, amount, Type, interest rate and, if applicable, Interest Period of each Loan made by each Lender, and all payments made on account of the principal thereof, shall be recorded by such Lender on its books for its Note, and, prior to any transfer, may be endorsed by such Lender on a schedule attached to such Note or any continuation thereof or on any separate record maintained by such Lender. Failure to make any such notation or to attach a schedule shall not affect any Lender’s or the Borrower’s rights or obligations in respect of such Loans or affect the validity of such transfer by any Lender of its Note.

Section 2.03 Requests for Borrowings. To request a Borrowing other than a Swingline Loan, the Borrower shall notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 12:00 noon, Chicago time, three Business Days before the date of the proposed Borrowing or (b) in the case of an ABR Borrowing, not later than 12:00 noon, Chicago 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, electronic mail or telecopy to the Administrative Agent of a written Borrowing Request substantially in 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”; and

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

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Each Borrowing Request shall be deemed to constitute a representation and warranty by the Borrower that the matters specified in Section 6.02(a) through (d) will be satisfied on the date of Borrowing specified in such Borrowing Request.

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. No such conversion or continuation shall be deemed the making of a new Borrowing for purposes of this Agreement, including without limitation ARTICLE 6.

(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, electronic mail or telecopy 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, subject to Section 2.04(e)(ii), 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 or the Interest Period specified in such Interest Election Request is not available to all Lenders, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration.

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

(e) Effect of Failure to Deliver Timely Interest Election Request and Events of Default 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 (i) an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Majority Lenders, so notifies the Borrower: (A) 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 (B) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto and (ii) a Borrowing Base Deficiency exists and the Administrative Agent, at the request of the Majority Lenders, so notifies the Borrower, no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing with an Interest Period longer than one month.

Section 2.05 Funding of Borrowings.

(a) Funding by Lenders. Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 1:00 p.m., Chicago time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders; provided that Swingline Loans shall be made as provided in Section 2.10. 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 that made such LC Disbursement. 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 (or, with respect to an ABR Borrowing, 1:00 p.m. Chicago time on the 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 such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

Section 2.06 Termination and Reduction of Aggregate Maximum Credit Amounts. (a) Scheduled Termination of Commitments. Unless previously terminated, the Commitments shall terminate on the Maturity Date. If at any time the Aggregate Maximum Credit Amounts are terminated or reduced to zero, then the Commitments shall terminate on the effective date of such termination or reduction.

(b) Optional Termination and Reduction of Aggregate Credit Amounts. (i) The Borrower may at any time terminate, or from time to time reduce, the Aggregate Maximum Credit Amounts; provided that (A) each reduction of the Aggregate Maximum Credit Amounts shall be in an amount that is an integral multiple of $1,000,000 and not less than $3,000,000 and (B) the Borrower shall not terminate or reduce the Aggregate Maximum Credit Amounts if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 3.04(c), the total Revolving Credit Exposures would exceed the total Commitments.

(ii) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Aggregate Maximum Credit Amounts 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; provided that a notice of termination of the Aggregate Maximum Credit Amounts delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Aggregate Maximum Credit Amounts shall be permanent and may not be reinstated. Each reduction of the Aggregate Maximum Credit Amounts shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage.

Section 2.07 Borrowing Base. (a) Initial Borrowing Base. For the period from and including the Effective Date to but excluding the first Redetermination Date, the amount of the Borrowing Base shall be $850,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments from time to time, whether before or after such Redetermination Date, pursuant to Section 8.12(c), Section 9.02(n) or Section 9.10.

(b) Scheduled and Interim Redeterminations. Subject to Section 2.07(d), the Borrowing Base shall be redetermined semi-annually (a “Scheduled Redetermination”) on or about the date that is 45 days following the Borrower’s delivery of a Reserve Report in accordance with Section 8.11(a). In addition, (i) the Borrower may, by notifying the Administrative Agent thereof, and (ii) the Administrative Agent may, at the direction of the Required Lenders, by notifying the Borrower thereof, each elect to cause the Borrowing Base to be redetermined one time between Scheduled Redeterminations (an “Interim Redetermination”) in accordance with this Section 2.07.

(c) Scheduled and Interim Redetermination Procedure. (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 8.11(a) and (c), and, in the case of an Interim Redetermination, pursuant to Section 8.11(b) and (c), and (B) such other reports, data and supplemental information including, without limitation, the information provided pursuant to Section 8.11(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 propose a new Borrowing Base (the “Proposed Borrowing Base”) based upon such information and such other information that is deemed appropriate by the Administrative Agent in its sole discretion in good faith and consistent with its normal oil and gas lending criteria as it exists at the particular time (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, the Borrower’s other assets, liabilities, fixed charges, cash flow, business, properties, prospects, management and ownership, hedged and unhedged exposure to price, price and production scenarios, interest rate and operating cost changes). In no event shall the Proposed Borrowing Base exceed 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 8.11(a) in a timely and complete manner, then on or before 30 days after the receipt of such Engineering Reports (or as promptly thereafter as may be reasonably practicable) or (2) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.11(a) 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

(B) in the case of an Interim Redetermination, promptly, and in any event, within 30 days after the Administrative Agent has received the required Engineering Reports (or as promptly thereafter as may be reasonably practicable).

(iii) Any Proposed Borrowing Base that would increase the Borrowing Base then in effect must be approved or deemed to have been approved by the Super-majority Lenders as provided in this Section 2.07(c)(iii); and any Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect must be approved or be deemed to have been 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 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 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 Super-majority 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 or deemed to 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 Required Lenders, in the case of a decrease or reaffirmation of the Borrowing Base, or the Super-majority Lenders, in the case of an increase to the Borrowing Base, have not approved or deemed to have approved, as aforesaid, then the Administrative Agent shall poll the Lenders to ascertain the highest Borrowing Base then acceptable to a number of Lenders sufficient to constitute the Required Lenders or the Super-majority Lenders, as applicable, and such amount shall become the new Borrowing Base, effective on the date specified in Section 2.07(d). The consent of the Borrower, in its sole discretion, shall be required for any increase in the Borrowing Base.

(d) Effectiveness of a Redetermined Borrowing Base. After a redetermined Borrowing Base is approved or is deemed to have been approved by the Required Lenders or the Super-majority Lenders, as applicable, pursuant to Section 2.07(c)(iii) (and, in the case of an increase, the Borrower), 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 amounts shall become the new Borrowing Base, effective and applicable to the Borrower, the Agents, each 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 8.11(a) and (c) in a timely and complete manner, then on the date of such New Borrowing Base Notice, or (B) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.11(a) and (c)

in a timely and complete manner, then on the Business Day next succeeding the date of such New Borrowing Base Notice; and

(ii) in the case of an Interim Redetermination, on the Business Day next succeeding the date of such New Borrowing Base 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 8.12(c), Section 9.02(n) or Section 9.10, 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.

Section 2.08 Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request any Issuing Bank to issue dollar denominated Letters of Credit for its own account or for the account of any of its Restricted Subsidiaries, in a form reasonably acceptable to the Administrative Agent and such Issuing Bank, at any time and from time to time during the Availability Period; provided, however, that no Letter of Credit shall be issued if, after such issuance, the LC Exposure would exceed the lesser of (A) the LC Commitment and (B) an amount equal to the aggregate Commitments minus the outstanding Loans, including Swingline Loans. 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, an Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

(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 telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the applicable Issuing Bank) to any Issuing Bank and the Administrative Agent (not less than three 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 issued by such Issuing Bank 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; and

(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.

Each such notice shall be deemed to constitute a representation and warranty by the Borrower that the matters specified in Section 6.02(a) through (d) will be satisfied on the date specified in clause (ii) of the immediately preceding sentence and that the LC Exposure will not exceed the LC Commitment on such date. No letter of credit issued by an Issuing Bank (if the Issuing Bank is not the Administrative Agent) shall be deemed to be a “Letter of Credit” issued under this Agreement unless such Issuing Bank has

confirmed with the Administrative Agent that the condition set forth in Section 6.02(d) hereof is satisfied and that the LC Exposure does not exceed the LC Commitment (after giving effect to the issuance of such letter of credit). If requested by any Issuing Bank, the Borrower also shall submit a letter of credit application on such Issuing Bank’s standard form in connection with any request for a Letter of Credit.

(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 any Letter of Credit with a one-year tenor may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in clause (ii) above).

(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 that issues such Letter of Credit or the Lenders, each Issuing Bank that issues a Letter of Credit hereunder hereby grants to each Lender, and each Lender hereby acquires from such Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of any Issuing Bank that issues a Letter of Credit hereunder, such Lender’s Applicable Percentage of each LC Disbursement made by such Issuing Bank and not reimbursed by the 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 Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If any Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit issued by such Issuing Bank, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 1:00 p.m., Chicago 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., Chicago 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 1:00 p.m., Chicago time, on (i) the Business Day that the Borrower receives such notice, if such notice is received prior to 10:00 a.m., Chicago 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 the Borrower may request 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. For purposes of the first sentence of Section 2.01, the amount of such ABR Borrowing shall be considered, but the amount of the LC Disbursement to be concurrently reimbursed shall not be considered. 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 that issued such Letter of Credit the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this Section 2.08(e),

the Administrative Agent shall distribute such payment to the Issuing Bank that issued such Letter of Credit or, to the extent that Lenders have made payments pursuant to this Section 2.08(e) to reimburse such Issuing Bank, then to such Lenders and such Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this Section 2.08(e) to reimburse an 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 any Issuing Bank under a Letter of Credit issued by such Issuing Bank against presentation of a draft or other document that does not comply with the terms of such Letter of Credit or any Letter of Credit Agreement, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.08(f), constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor any Issuing Bank, nor any of their Related Parties shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of any Issuing Bank; provided that the foregoing shall not be construed to excuse any Issuing Bank from liability to the 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 such Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of any Issuing Bank (as finally determined by a court of competent jurisdiction), such Issuing Bank shall be deemed to have exercised all requisite care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank that issued such Letter of Credit may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g) Disbursement Procedures. Each Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit issued by such Issuing Bank. Such Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by electronic mail or telecopy) of such demand for payment and whether such 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 such Issuing Bank and the Lenders with respect to any such LC Disbursement.

(h) Interim Interest. If any Issuing Bank shall make any LC Disbursement, then, until the Borrower shall have reimbursed such Issuing Bank for such LC Disbursement (either with its own funds or a Borrowing under Section 2.08(e)), the unpaid amount thereof shall bear interest, for each day from

and including the date such LC Disbursement is made to but excluding the date that the 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 such Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.08(e) to reimburse such Issuing Bank shall be for the account of such Lender to the extent of such payment.

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

(j) Cash Collateralization. If (i) any Event of Default shall occur and be continuing and the Borrower receives notice from the Administrative Agent or the Majority 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 account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to, 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 Guarantor described in Section 10.01(h) or Section 10.01(i). The Borrower hereby grants to the Administrative Agent, for the benefit of each Issuing Bank and the Lenders, an exclusive first priority and continuing perfected security interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all deposits or wire transfers made thereto, any and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise payable in respect of, or in exchange for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. The 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 its Subsidiaries may now or hereafter have against any such beneficiary, any Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such deposit shall be held as collateral securing the payment and performance of the Borrower’s and the Guarantor’s 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 such 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 such account. Moneys in such account shall be applied by the Administrative Agent to reimburse, on a pro rata basis, each Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the 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. In the event of any such payment by the Borrower of amounts contingently owing under outstanding Letters of Credit and in the event that thereafter drafts or other demands for payment complying with the terms of such Letters of Credit are not made on or prior to the respective expiration dates thereof, the Administrative Agent agrees, if no Default is then continuing and the Borrower does not have any obligation at such time to provide cash collateral under Section 2.11 hereof, or if no other amounts are then outstanding under this Agreement, the Notes or the Loan Documents, to remit to the Borrower amounts for which the contingent obligations evidenced by the Letters of Credit have ceased (but only to the extent of the amount of cash collateral then on deposit with the Administrative Agent in respect of such Letters of Credit). 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.

Section 2.09 Increase in the Maximum Credit Amounts. (a) The Borrower may, with the consent of the Administrative Agent (such consent not to be unreasonably withheld, conditioned or delayed), on no more than five occasions during the period beginning on the Effective Date to and including the date that is six months prior to the Maturity Date, by written notice to the Administrative Agent executed by the Borrower and one or more financial institutions (any such financial institution executing such notice being called an “Increasing Lender”), which may include any Lender, cause the Maximum Credit Amounts to be extended by the Increasing Lenders if such Increasing Lender is not already a Lender (or cause the Maximum Credit Amounts of the Increasing Lenders that are already Lenders to be increased, as the case may be) in an amount for each Increasing Lender set forth in such notice; provided, that (i) each extension of new Maximum Credit Amounts or increase in existing Maximum Credit Amounts pursuant to this paragraph shall result in the aggregate Maximum Credit Amounts being increased by no less than $17,500,000, (ii) the sum of all new Maximum Credit Amounts and increases in existing Maximum Credit Amounts pursuant to this paragraph shall not exceed $250,000,000 without the approval of all Lenders, (iii) each Increasing Lender, if not already a Lender, shall be subject to the approval of the Administrative Agent, each Issuing Bank and the Swingline Lender (which approval shall not be unreasonably withheld, conditioned or delayed), (iv) each Increasing Lender, if not already a Lender hereunder, shall become a party to this Agreement by completing and delivering to the Administrative Agent a duly executed joinder agreement in a form reasonably satisfactory to the Administrative Agent and the Borrower (a “Joinder Agreement”), (v) any Lender requested by the Borrower to become an Increasing Lender may elect, or decline, such request in its sole discretion and (vi) no Default has occurred and is continuing.

(b) Upon the effectiveness of any Joinder Agreement to which any Increasing Lender is a party, (i) such Increasing Lender shall thereafter be deemed to be a party to this Agreement and shall be entitled to all rights, benefits and privileges accorded a Lender hereunder and subject to all obligations of a Lender hereunder and (ii) Annex I shall be deemed to have been amended to reflect the Maximum Credit Amount of such Increasing Lender as provided in such Joinder Agreement. Upon the effectiveness of any increase pursuant to this Section 2.09 in the Maximum Credit Amount of a Lender already a party hereto, Annex I shall be deemed to have been amended to reflect the increased Maximum Credit Amount of such

Lender. Notwithstanding the foregoing, no increase in the Aggregate Maximum Credit Amounts (or in the Maximum Credit Amount of any Lender) shall become effective under this Section unless, on the date of such increase, the Administrative Agent shall have received (i) a certificate, dated as of the effective date of such increase and executed by a Financial Officer of the Borrower, to the effect that the conditions set forth in paragraphs (a) and (c) of Section 6.02 shall be satisfied (with all references in such paragraphs to a Borrowing being deemed to be references to such increase and attaching resolutions of the Borrower approving such increase) and (ii) if requested by the Administrative Agent, a legal opinion in form and substance reasonably satisfactory to the Administrative Agent. The Administrative Agent shall provide notice to the Borrower and the Lenders of the effectiveness of any such Joinder Agreement and/or any increase in the Aggregate Maximum Credit Amounts (or in the Maximum Credit Amount of any Lender) and the foregoing shall be effective as of the date of such notice.

(c) The Borrower shall prepay any Loans outstanding prior to the effectiveness of such increase or extension, together with any amounts due pursuant to Section 5.02, with new Loans made pursuant to Section 2.01 ratably in accordance with the Maximum Credit Amounts in effect following such extension or increase.

Section 2.10 Swingline Loans. (a) Subject to the terms and conditions hereof, the Swingline Lender agrees to make a portion of the credit otherwise available to the Borrower under the Commitments from time to time until the Termination Date by making swing line loans (“Swingline Loans”) to the Borrower; provided that (i) the aggregate outstanding principal amount of Swingline Loans owed to the Swingline Lender at any time shall not exceed its Swingline Commitment then in effect (notwithstanding that the outstanding Swingline Loans owed to the Swingline Lender at any time, when aggregated with the Swingline Lender’s other outstanding Loans, may exceed its Commitment then in effect) and (ii) the Borrower shall not request, and the Swingline Lender shall not make, any Swingline Loan if, after giving effect to the making of such Swingline Loan, the aggregate amount (without duplication) of the Loans, the Swingline Loans and the LC Exposure would exceed the aggregate Commitments; provided that the Swingline Lender may not make a Swingline Loan to refinance an outstanding Swingline Loan. Prior to the Termination Date, the Borrower may use the Swingline Commitment by borrowing, repaying (in whole or part) and reborrowing, all in accordance with the terms and conditions hereof.

(b) The Borrower shall repay to the Swingline Lender the then unpaid principal amount of each Swingline Loan made by the Swingline Lender on or before the earlier of (i) the Termination Date and (ii) the first date after such Swingline Loan is made that is the 15th or last day of a calendar month and is at least five (5) Business Days after such Swingline Loan is made. The unpaid principal amount of each Swingline Loan shall bear interest at the per annum rate equal to Alternate Base Rate in effect from time to time plus the Applicable Margin for ABR Loans.

(c) The obligation of the Swingline Lender to make Swingline Loans to the Borrower is subject to the same conditions precedent for the making of Loans under Section 6.02.

(d) Whenever the Borrower desires that the Swingline Lender make Swingline Loans it shall give irrevocable telephonic notice to JPMorgan, as Administrative Agent and the Swingline Lender, confirmed promptly in writing (which telephonic notice must be received by the Swingline Lender not later than 1:30 p.m., Chicago time, on the proposed date Swingline Loans are requested to be made), specifying (i) the amount to be borrowed and (ii) the requested date such Swingline Loans are to be advanced (which shall be a Business Day). Each borrowing under the Swingline Commitment shall be in an amount not less than $500,000 and a whole multiple of $100,000 in excess thereof. As soon as such funds are available, but in any event not later than 3:00 p.m., Chicago time, on the date such Swingline Loans are requested to be advanced pursuant to the Borrower’s corresponding written request referenced above, the Swingline Lender shall make available to the Administrative Agent at the office designated by

the Administrative Agent for such purpose an amount in immediately available funds equal to the amount of the Swingline Loans to be made by the Swingline Lender. The Administrative Agent shall make the proceeds of such Swingline Loan available to the Borrower at such office in immediately available funds as soon as such funds are available, but in any event not later than 3:00 p.m., Chicago time, on the date such Swingline Loans are requested to be advanced pursuant to the Borrower’s corresponding written request.

(e) The Swingline Lender, at any time and from time to time in its sole and absolute discretion may, on behalf of the Borrower (which hereby irrevocably authorizes the Swingline Lender to so act on its behalf), by written notice to the Administrative Agent and each Lender, with copy to the Borrower, given by the Swingline Lender no later than 11:00 a.m., Chicago time, require each Lender to make, and each Lender hereby agrees to make, a Loan, in an amount equal to such Lender’s Applicable Percentage of the aggregate amount of the Swingline Lender’s Swingline Loans (the “Refunded Swingline Loans”) outstanding on the date of such notice, to repay the Swingline Lender. Each Lender shall make the amount of such Loan available to the Administrative Agent at such office in immediately available funds, not later than 10:00 a.m., Chicago time, one Business Day after the date of such notice. The proceeds of such Loans shall be immediately made available by the Administrative Agent to the Swingline Lender for application by it to the repayment of the Refunded Swingline Loans.

(f) If prior to the time a Refunded Swingline Loan would have otherwise been made pursuant to Section 2.10(e), one of the events described in Section 10.01(h) or Section 10.01(i) shall have occurred and be continuing with respect to the Borrower or if for any other reason, as determined by the Swingline Lender in its sole discretion, Loans may not be made as contemplated by Section 2.10(e), each Lender shall, on the date such Loan was to have been made pursuant to the notice referred to in Section 2.10(e), purchase for cash an undivided participating interest in the then outstanding Swingline Loans by paying to the Swingline Lender an amount (the “Swingline Participation Amount”) equal to (i) such Lender’s Applicable Percentage times (ii) the sum of the aggregate principal amount of Swingline Loans then outstanding to the Swingline Lender that were to have been repaid with such Loans.

(g) Whenever, at any time after the Swingline Lender has received from any Lender such Lender’s Swingline Participation Amount, the Swingline Lender receives any payment on account of outstanding Swingline Loans, the Swingline Lender will distribute to such Lender its Swingline Participation Amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s participating interest was outstanding and funded and, in the case of principal and interest payments, to reflect such Lender’s pro rata portion of such payment if such payment is not sufficient to pay the principal of and interest on all Swingline Loans then due); provided, however, that in the event that such payment received by the Swingline Lender is required to be returned, such Lender will return to the Swingline Lender any portion thereof previously distributed to it by the Swingline Lender.

(h) Each Lender’s obligation to make the Loans referred to in Section 2.10(e) and to purchase participating interests pursuant to Section 2.10(f) shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any setoff, counterclaim, recoupment, defense or other right that such Lender or the Borrower may have against the Swingline Lender, the Borrower or any other Person for any reason whatsoever, (ii) the occurrence or continuance of an Event of Default or the failure to satisfy any of the other conditions specified in Section 6.02, (iii) any adverse change in the condition (financial or otherwise) of the Borrower, (iv) any breach of this Agreement or any other Loan Document by the Borrower, any Guarantor or any other Lender or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.

Section 2.11 Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(a) Commitment fees will cease to accrue on the unfunded portion of the Commitment of the Defaulting Lender pursuant to Section 3.05(a) and such Defaulting Lender shall not be entitled to receive any commitment fee pursuant to Section 3.05(a);

(b) If any Swingline Loans are outstanding or any LC Exposure exists at the time a Lender is a Defaulting Lender then solely for purposes of computing the amount of the obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Swingline Loans and Letters of Credit pursuant to Section 2.08 and Section 2.10:

(i) all or any part of the Swingline Participation Amount and LC Exposure of such Defaulting Lender shall be reallocated among the non-Defaulting Lenders in accordance with their respective Applicable Percentages but only to the extent that (x) the sum of all non-Defaulting Lenders’ Revolving Credit Exposures does not exceed the total of all non-Defaulting Lenders’ Commitments, (y) each non-Defaulting Lender’s total Revolving Credit Exposure may not in any event exceed the Commitment of such Non-Defaulting Lender as in effect at the time of such reallocation and (z) the conditions set forth in Section 6.02 are satisfied at such time;

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall within three Business Days following notice by the Administrative Agent given no later than 12:00 noon, Chicago time (x) first, prepay the Swingline Participation Amount of the Defaulting Lender to the Swingline Lender and (y) second, cash collateralize such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.08(j) for so long as such LC Exposure is outstanding;

(iii) if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to this Section 2.11(b), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 3.05(b) with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized; if the LC Exposure of the non-Defaulting Lenders is reallocated pursuant to this Section 2.11, then the fees payable to the Lenders pursuant to Section 3.05(a) and Section 3.05(b) shall be adjusted in accordance with such non-Defaulting Lenders’ Applicable Percentages with the balance of such fee, if any, being retained by the Borrower for its own account or, to the extent any LC Exposure shall then be outstanding, being payable to each applicable Issuing Bank for its own account to the extent such fee relates to the amount of such LC Exposure; or

(iv) if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to this Section 2.11, then, without prejudice to any rights or remedies of any Issuing Bank or any Lender hereunder, all commitment fees that otherwise would have been payable to such Defaulting Lender (solely with respect to the portion of such Defaulting Lender’s Commitment that was utilized by such LC Exposure) and Letter of Credit fees payable under Section 3.05(b) with respect to such Defaulting Lender’s LC Exposure shall be payable to each applicable Issuing Bank until such LC Exposure is cash collateralized and/or reallocated.

(c) Notwithstanding any provision of this Agreement to the contrary, so long as any Lender is a Defaulting Lender, the Swingline Lender shall not be required to fund any Swingline Loan and no Issuing Bank shall be required to issue, amend or increase any Letter of Credit unless it is satisfied that the

related exposure will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance with Section 2.08(j), and participating interests in any such newly issued or increased Letter of Credit or newly made Swingline Loan shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.11(b)(i) (and Defaulting Lenders shall not participate therein).

(d) Any amount payable to such Defaulting Lender hereunder (whether on account of principal, interest, fees or otherwise and including any amount that would otherwise be payable to such Defaulting Lender pursuant to Section 4.01(c) or Section 10.02(c), but excluding Section 5.04(b)) will, in lieu of being distributed to such Defaulting Lender, be retained by the Administrative Agent in a segregated account and, subject to any applicable requirements of law, be applied at such time or times as may be determined by the Administrative Agent (i) first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder, (ii) second, pro rata, to the payment of any amounts owing by such Defaulting Lender to each Issuing Bank and the Swingline Lender hereunder, (iii) third, to cash collateralize such Defaulting Lender’s LC Exposure in accordance with Section 2.08(j), (iv) fourth, as the Borrower may request (so long as no Default exists), to the funding of any Loan or Swingline Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent, (v) fifth, if so determined by the Administrative Agent and the Borrower, held in an interest bearing account and released pro rata in order to (A) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement and (B) cash collateralize such Defaulting Lender’s future LC Exposure in accordance with Section 2.08(j), (vi) sixth, to the payment of any amounts then owing to the Lenders, any Issuing Bank or the Swingline Lender as a result of any final and non-appealable judgment of a court of competent jurisdiction obtained by any Lender, Issuing Bank or Swingline Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement, (vii) seventh, to the payment of any amounts then owing to the Borrower as a result of any final and non-appealable judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement and (viii) eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if such payment is (x) a prepayment of the principal amount of any Loans or reimbursement obligations in respect of LC Disbursement or Swingline Participation Amount that a Defaulting Lender has not fully funded its participation obligations and (y) in the case of such Loans which were made at a time when the conditions set forth in Section 6.02 were satisfied or waived, such payment will be applied solely to prepay the Loans of, and reimbursement obligations owed to, all non-Defaulting Lenders pro rata prior to being applied to the prepayment of any Loans, or reimbursement obligations owed to, any Defaulting Lender. Any payments, prepayments or other amounts paid or payable to any Defaulting Lender that are applied (or held) to pay amounts owed by such Defaulting Lender or to post cash collateral pursuant to Section 2.11 shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents to the foregoing.

(e) If any Lender is a Defaulting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to be replaced in accordance with Section 5.04(b).

(f) In the event that the Administrative Agent, the Borrower, the Issuing Banks and the Swingline Lender each agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the Swingline Participation Amounts and LC Exposure of the Lenders shall be readjusted to reflect the inclusion of such Defaulting Lender’s Commitment and on such date such Defaulting Lender shall purchase at par such of the Loans of the other Lenders (other than Swingline Loans) as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Applicable Percentage; 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 to Lender will constitute a waiver or release of any claim that the Borrower, the Administrative Agent, the Issuing Banks, the Swingline Lender, or any other Lender may have against such Defaulting Lender or cause such Defaulting Lender to be a non-Defaulting Lender except as expressly set forth above.

ARTICLE 3
Payments of Principal and Interest; Prepayments; Fees

Section 3.01 Repayment of Loans. The Borrower hereby unconditionally promises to pay (a) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan on the Termination Date and (b) the Swingline Lender the unpaid principal amount of each Swingline Loan in accordance with Section 2.10(b).

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 for ABR Loans, 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 for Eurodollar Loans, but in no event to exceed the Highest Lawful Rate.

(c) Default Rate. Notwithstanding the foregoing, 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, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, the lesser of (A) the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section plus 2% or (B) the Highest Lawful Rate or (ii) in the case of any other amount, the lesser of (A) the Default Rate or (B) 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 (but only to the extent so converted).

(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, as applicable, for such Interest Period; or

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

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

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 (and, in the case of prepayment of a Swingline Loan, the Swingline Lender) by telephone (confirmed by electronic mail or telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, Chicago time, three Business Days before the date of prepayment, or (ii) in the case of prepayment of an ABR Borrowing or Swingline Loan, not later than 12:00 noon, Chicago time, one Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the Borrowing to be prepaid, the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.06(b), then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.06(b). 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. The Administrative Agent shall apply each prepayment of a Borrowing ratably to the Loans included in the Borrowing specified in the Borrower’s notice of prepayment. 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 Maximum Credit Amounts pursuant to Section 2.06(b), the total Revolving Credit Exposures exceeds the total Commitments, 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) Upon any redetermination of or adjustment to the amount of the Borrowing Base in accordance with Section 2.07, Section 8.12(c) or Section 9.10 (solely as a result of a Casualty Event), if the total Revolving Credit Exposures exceeds the redetermined or adjusted Borrowing Base, then the Borrower shall, at its option, either (A) make (or cause to be made) a single payment of principal in an amount equal to such Borrowing Base Deficiency and, if any Borrowing Base Deficiency 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 remaining excess to be held as cash collateral as provided in Section 2.08(j), in each case, within thirty (30) days following its receipt of the New Borrowing Base Notice in accordance with Section 2.07(d) or the date the adjustment occurs (the “Deficiency Notification Date”), (B) make (or cause to be made) six payments of principal each of which shall be in an amount equal to one-sixth (1/6th) of such Borrowing Base Deficiency commencing on the 15th day of a calendar month that is at least thirty (30) days following the Deficiency Notification Date and on the 15th day of each of the five calendar months thereafter, (C) within forty-five (45) days following the Deficiency Notification Date, submit (and pledge as Collateral) additional Oil and Gas Properties owned by the Borrower or any of its Domestic Subsidiaries which are or shall become a Guarantor contemporaneously with such submission pursuant to Section 8.13 for consideration in connection with the determination of the Borrowing Base which the Administrative Agent and the Required Lenders deem satisfactory, in their sole discretion, to eliminate such Borrowing Base Deficiency or (D) within thirty (30) or forty-five (45) days following the Deficiency Notification Date, as applicable, eliminate such Borrowing Base Deficiency through a combination of a payment and submission of additional Oil and Gas Properties as set forth in clauses (A) and (C) above; provided that all payments required to be made pursuant to this Section 3.04(c)(ii) must be made on or prior to the Termination Date. Not later than 15 days following the Deficiency Notification Date, the Borrower shall provide written notice to the Administrative Agent setting forth its election pursuant to the immediately preceding sentence.

(iii) Upon any adjustments to the Borrowing Base pursuant to Section 9.02(n) or Section 9.10 (other than adjustments resulting directly from Casualty Events), if the total Revolving Credit Exposures exceeds the Borrowing Base as adjusted, then the Borrower shall (A) prepay the Borrowings in an aggregate principal amount equal to such Borrowing Base Deficiency, 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). The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral (x) within thirty (30) days following the effective date of any such adjustment to the Borrowing Base under Section 9.02(n) or (y) prior to or contemporaneously with such adjustment to the Borrowing Base under Section 9.10 (other than adjustments resulting directly from Casualty Events); provided that all payments required to be made pursuant to this Section 3.04(c)(iii) must be made on or prior to the Termination Date.

(iv) 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 highest interest rate applicable thereto and ending with the Eurodollar Borrowing with the lowest interest rate applicable thereto.

(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.

Section 3.05 Fees.

(a) Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Lender (other than a Defaulting Lender to the extent set forth in Section 2.11) a commitment fee, which shall accrue at the applicable Commitment Fee Rate on the average daily amount of the unused 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 third Business Day following 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 Effective Date. 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 (other than a Defaulting Lender to the extent set forth in Section 2.11) a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Margin used to determine the interest rate applicable to Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements which has been funded by such Lender) 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 each Issuing Bank a fronting fee, which shall accrue at the rate per annum agreed to with such Issuing Bank on the average daily amount of that portion of the LC Exposure attributable to such Issuing Bank (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 attributable to such Issuing Bank, provided that (x) if the expiration date of the Letter of Credit is less than one year after its date of issuance and the aggregate fronting fee otherwise payable through its expiration would be less than $500, then the Borrower shall pay to such Issuing Bank $500 upon the issuance of such Letter of Credit in lieu of the fronting fee otherwise payable and (y) no fronting fee shall be payable with respect to any Grandfathered Letters of Credit on the Effective Date or thereafter, until and unless such Grandfathered Letter of Credit is extended, renewed or reissued hereunder, and (iii) to each 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 in arrears 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 an Issuing Bank pursuant to this Section 3.05(b) shall be payable within 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days, 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).

(c) 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 4
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 2:00 p.m., Chicago time, on the date when due (for purposes of computing interest and fees, each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day), 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, absent manifest error. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices specified in Section 12.01, except payments to be made directly to an Issuing Bank as expressly provided herein and except that payments pursuant to Section 5.01, Section 5.02, Section 5.03 and Section 12.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in Dollars.

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

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

the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

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

Section 4.03 Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it hereunder, pursuant to Section 2.05(a), Section 2.08(d), Section 2.08(e) or Section 4.02 or otherwise, 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 Secured Indebtedness and other obligations described therein and secured thereby. Notwithstanding anything to the contrary contained in the 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 production from or allocated to the Mortgaged Property nor take any other action to cause the proceeds thereof to be remitted to the Administrative Agent or the Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrower and its Restricted Subsidiaries and (b) the Lenders hereby authorize the Administrative Agent to take such actions as may be necessary to cause such proceeds to be paid to the Borrower and/or such Restricted Subsidiaries.

ARTICLE 5
Increased Costs; Break Funding Payments; Payments; Taxes; Illegality

Section 5.01 Increased Costs.

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

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

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

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or otherwise, but not including Excluded Taxes), then the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

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

(c) Certificates. A certificate of a Lender or any Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or such Issuing Bank or its holding company, as the case may be, as specified in Section 5.01(a) or (b) shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or such Issuing Bank, as the case may be, the amount shown as due on any such certificate within 30 days after receipt thereof.

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

Section 5.02 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan into an ABR Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow as a result of a failure to satisfy the conditions set forth in Section 6.02, 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(a), then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event (exclusive of any lost profits or opportunity costs or processing or other related fees). 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 Business Days after receipt thereof.

Section 5.03 Taxes.

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

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

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Lender and each Issuing Bank, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or such Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 5.03) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority; provided that the Borrower shall not be required to indemnify the Administrative Agent, any Lender or any Issuing Bank for any amounts under this Section 5.03(c) to the extent that such Person fails to notify the Borrower of its intent to make a claim for indemnification under this Section 5.03(c) within 180 days after a claim is asserted against such Person by the relevant Governmental Authority. A certificate of the Administrative Agent, a Lender or an Issuing Bank as to the amount of such payment or liability under this Section 5.03, together with, to the extent available, reasonable supporting documentation relating to such payment or liability, shall be delivered to the Borrower and shall be conclusive absent manifest error.

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

(e) 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(e)(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:

(1) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN 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;

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

(3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit H-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

(4) to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit H-2 or Exhibit H-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 H-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.

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

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

Section 5.04 Mitigation Obligations; Replacement of Lenders.

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

(b) Replacement of Lenders. If (i) any Lender requests compensation under Section 5.01, or (ii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, or (iii) any Lender is a Defaulting Lender, or (iv) any Lender has asserted that any adoption or change of the type described in Section 5.05 has occurred, or (v) any Lender fails to approve an amendment, waiver or other modification to this Agreement and at least the Required Lenders have approved such amendment, waiver or other modification, or (vi) any Lender fails to approve an increase of the Borrowing Base and at least the Required Lenders have approved such increase, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 12.04(b)), all its interests, rights and obligations under this Agreement to an assignee that shall (A) assume such obligations and (B) in the case of clauses (v) and (vi), consent to such amendment, waiver, modification, increase, decrease or reaffirmation (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) if such assignee is not a Lender, the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 5.01 or payments required to be made pursuant to Section 5.03, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

Section 5.05 Illegality. Notwithstanding any other provision of this Agreement:

(b) If it becomes unlawful for any Lender or its applicable lending office to honor its obligation to make any Loans to the Borrower, then such Lender shall promptly notify the Borrower and the Administrative Agent thereof and such Lender’s obligation to make Loans shall be suspended until such time as such Lender may again make and maintain Loans to the Borrower.

No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, would reasonably be expected to result in a Material Adverse Effect.

value of the benefit liabilities (within the meaning of section 4041 of ERISA) under each Plan which is subject to Title IV of ERISA does not, as of the end of the most recently ended fiscal year, exceed the current value of the assets (computed on a plan termination basis in accordance with Title IV of ERISA) of such Plan allocable to such benefit liabilities.

(b) In the event of an Interim Redetermination requested by the Administrative Agent or the Borrower pursuant to Section 2.07(b), the Borrower shall, upon the request of the Administrative Agent, furnish to the Administrative Agent and the Lenders a Reserve Report (i) prepared by or under the supervision of the chief engineer of the Borrower and in accordance with the procedures used in the immediately preceding Prepared Reserve Report delivered pursuant to Section 8.11(a), and (ii) which shall have an “as of” date as required by the Administrative Agent, no later than a date mutually agreed to by the Borrower and the Administrative Agent. If the Administrative Agent does not request an updated Reserve Report pursuant to the immediately preceding sentence, the Administrative Agent and the Lenders may base such Interim Redetermination on the Reserve Report most recently delivered by the Borrower hereunder.

(c) With the delivery of each Reserve Report, the Borrower shall provide to the Administrative Agent and the Lenders a certificate from a Responsible Officer certifying that in all material respects: (i) the information contained in the Reserve Report and any other information delivered

in connection therewith is true and correct, (ii) subject to Immaterial Title Deficiencies, the Borrower or a Guarantor owns good and defensible title to the Oil and Gas Properties evaluated in such Reserve Report and such Properties are free of all Liens except for Permitted Liens and Liens securing the Secured Indebtedness, (iii) except as set forth on an exhibit to the certificate, on a net basis there are no gas imbalances, take or pay or other prepayments in excess of one half bcf of gas in the aggregate with respect to its Oil and Gas Properties evaluated in such Reserve Report which would require the Borrower or any Guarantor to deliver Hydrocarbons either generally or produced from such Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor, (iv) attached to the certificate is a list of all marketing agreements entered into subsequent to the later of the date hereof or the most recently delivered Reserve Report which pertain to the sale of production at a fixed price and have a maturity date of longer than six (6) months from the date of such certificate, and (v) a true and complete list of all Oil and Gas Swap Agreements of the Borrower and each Restricted Subsidiary is included, which list contains the material terms thereof (including the type, remaining term, counterparty, ▇▇▇▇-to-market value as of the end of the second month immediately preceding the date of such certificate and notional amounts or volumes), any credit support agreements relating thereto, any margin required or supplied under any credit support document, and the counterparty to each such agreement.

Section 8.12 Title Information. (a) On or before the date that is 45 days following the delivery to the Administrative Agent and the Lenders of each Reserve Report required by Section 8.11(a), the Borrower will deliver title information in form and substance reasonably 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 75% of the total value of the Proved Hydrocarbon Interests evaluated by such Reserve Report.

(b) If the Borrower has provided title information for additional Oil and Gas Properties under Section 8.12(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 Permitted Liens 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 75% of the value of the Proved Hydrocarbon Interests evaluated by such Reserve Report. For purposes of this Section 8.12(b), the Administrative Agent must deliver any notice of title defects or exceptions with respect to any Oil and Gas Properties within 60 days following the Administrative Agent’s receipt of title information for such Oil and Gas Properties.

(c) If the Borrower is unable to cure any title defect requested by the Administrative Agent or the Lenders to be cured within the 60-day period or the Borrower does not comply with the requirements to provide acceptable title information covering 75% of the value of the Proved Hydrocarbon Interests evaluated in the most recent Reserve Report, such default shall not be a Default, but instead the Administrative Agent, at the direction of the Required Lenders, shall have the right to exercise the following remedy in their sole discretion from time to time, and any failure to so exercise this remedy at any time shall not be a waiver as to future exercise of the remedy by the Administrative Agent or the Lenders. To the extent that the Administrative Agent is not reasonably satisfied with title to any Mortgaged Property after the 60-day period has elapsed, such unacceptable Mortgaged Property shall not count towards the 75% 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 75% of the value of the Proved Hydrocarbon Interests. This new Borrowing Base shall become effective immediately after receipt of such notice by the Borrower.

Section 8.13 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 to ascertain whether the Mortgaged Properties represent at least 80% of the total value of the Proved Hydrocarbon Interests evaluated in the most recently completed Reserve Report after giving effect to exploration and production activities, acquisitions, dispositions and production. In the event that the Mortgaged Properties do not represent at least 80% of such total value, then the Borrower shall, and shall cause its Restricted Subsidiaries to, grant, within 30 days of the delivery of the certificate required under Section 8.11(c) (or such longer period as the Administrative Agent may agree in its discretion), to the Administrative Agent as security for the Secured Indebtedness a first-priority Lien interest (provided that Permitted Liens may exist) on additional Oil and Gas Properties evaluated in the most recently completed Reserve Report containing Proved Hydrocarbon Interests 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 total value. All such Liens will be created and perfected by and in accordance with the provisions of 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. Notwithstanding anything to the contrary contained in this Agreement, if any Restricted Subsidiary places a Lien on its Oil and Gas Properties to secure the Secured Indebtedness and such Restricted Subsidiary is not a Guarantor, then it shall become a Guarantor and comply with Section 8.13(c).

(b) If the Borrower or any Restricted Subsidiary becomes the owner of a Restricted Subsidiary, then the Borrower shall, or shall cause such Restricted Subsidiary to, promptly, but in any event no later than 30 days after the date of becoming an owner thereof (or such longer period as the Administrative Agent may agree in its discretion), (i) pledge (x) 100% of the Equity Interests of such new Restricted Subsidiary if such Subsidiary is a Domestic Subsidiary or (y) 65% of the total combined voting power of all classes of Equity Interests and 100% of all non-voting Equity Interests of such new Restricted Subsidiary, if such new Restricted Subsidiary is a Foreign Subsidiary (including, without limitation, delivery of original stock certificates evidencing the Equity Interests of such new Restricted Subsidiary, together with appropriate undated stock powers for each certificate duly executed in blank by the registered owner thereof) and (ii) execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent.

(iii) any Person that guarantees any Existing Debt or any Permitted Additional Debt;

(iv) any Restricted Subsidiary that places a Lien as required by the last sentence of Section 8.13(a) on its Oil and Gas Properties to secure the Secured Indebtedness; and

(v) one or more additional Restricted Subsidiaries to the extent necessary to cause (A) the total assets of the Restricted Subsidiaries that are not Guarantors to be less than 15% of

the combined assets of the Borrower and its Restricted Subsidiaries and (B) the combined EBITDAX of such Restricted Subsidiaries to be less than 15% of the combined EBITDAX of the Borrower and its Restricted Subsidiaries.

(d) In connection with any guaranty required by Section 8.13(c), the Borrower shall, or shall cause such Subsidiary or other Person to promptly, but in any event no later than 30 days (or such longer period as the Administrative Agent may agree in its discretion) after the event requiring such guaranty, execute and deliver (i) a supplement to the Guaranty Agreement and (ii) such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent. If at any time any Person is not otherwise required to guarantee the Secured Indebtedness hereunder (whether pursuant to the other provisions of this Section 8.13 or otherwise) or under any other Loan Document, then upon receipt by the Administrative Agent of evidence satisfactory to it that such Person has been fully and finally released from its guarantee obligations in respect of the Existing Debt or, if applicable, any Permitted Additional Debt, as the case may be, such Person shall be released from its guarantee obligations with respect to the Secured Indebtedness and the Administrative Agent shall, at the sole cost and expense of the Borrower, execute such further documents and do all such further acts so as to reasonably evidence such release.

(e) The Borrower shall not permit any Canadian Subsidiary to guarantee any Existing Debt or any Permitted Additional Debt.

Section 9.12 Negative Pledge Agreements; Dividend Restrictions. The Borrower will not, and will not permit any Restricted Subsidiary to, create, incur, assume or suffer to exist any contract, agreement or understanding which in any way prohibits or restricts the granting, conveying, creation or imposition of any Lien on any of its Oil and Gas Property or its Equity Interests in Restricted Subsidiaries in favor of the Administrative Agent and the Secured Parties or restricts any Restricted 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; provided, however, that the preceding restrictions will not apply to encumbrances or restrictions arising under or by reason of (a) this Agreement or the Security Instruments, (b) Debt permitted by Section 9.02 secured by Liens permitted by Section 9.03 (subject to the penultimate sentence thereof and only to the extent related to the Property on which such Liens were created), or any contract, agreement or understanding creating Liens permitted by Section 9.03 (subject to the penultimate sentence thereof and only to the extent related to the Property on which such Liens were created), (c) any leases or licenses or similar contracts as they affect any Oil and Gas Property or Lien subject to a lease or license, (d) any restriction with respect to a Restricted Subsidiary imposed pursuant to an agreement entered into for the direct or indirect sale or disposition of all or substantially all the equity or Oil and Gas Property of such Restricted Subsidiary (or the Oil and Gas Property that is subject to such restriction) pending the closing of such sale or disposition, or (e) customary provisions with respect to the distribution of Oil and Gas Property in joint venture agreements.

Section 9.13 Swap Agreements. The Borrower will not, nor will the Borrower permit any Restricted Subsidiary to, enter into any new Oil and Gas Swap Agreements which would cause the volume of Hydrocarbons with respect to which a settlement payment is calculated under all Oil and Gas Swap Agreements (including such new transactions) to which the Borrower and/or any Restricted Subsidiary is a party as of the date such Oil and Gas Swap Agreements are entered into to exceed (a) (i)

for the calendar year in which such new Oil and Gas Swap Agreements are entered into (the “Initial Measurement Period”), eighty-five percent (85%) of the aggregate of the Borrower’s and its Restricted Subsidiaries’ anticipated production from Proved Hydrocarbon Interests for each of oil and gas (including natural gas liquids), calculated separately, (ii) for the calendar year immediately following the end of the Initial Measurement Period (the “Second Measurement Period”), eighty percent (80%) of the aggregate of the Borrower’s and its Restricted Subsidiaries’ anticipated production from Proved Hydrocarbon Interests for each of oil and gas (including natural gas liquids), calculated separately, (iii) for the calendar year immediately following the end of the Second Measurement Period (the “Third Measurement Period”), seventy-five percent (75%) of the aggregate of the Borrower’s and its Restricted Subsidiaries’ anticipated production from Proved Hydrocarbon Interests for each of oil and gas (including natural gas liquids), calculated separately and (iv) for the calendar year immediately following the end of the Third Measurement Period and for each calendar year thereafter, one hundred percent (100%) of the aggregate of the Borrower’s and its Restricted Subsidiaries’ anticipated production from Proved Producing Hydrocarbon Interests for each of oil and gas (including natural gas liquids), calculated separately, plus, in each case, (b) an amount not to exceed one hundred percent (100%) of associated royalty owners’ oil, gas and/or natural gas liquids produced from the same ▇▇▇▇▇, and which oil, gas and/or natural gas liquids the Borrower has the authority to market and sell, during the applicable measurement period; provided that the Borrower will not, nor will the Borrower permit any Restricted Subsidiary to, permit its production from Proved Producing Hydrocarbon Interests (whether or not included or reflected in the most recent Reserve Report delivered to the Administrative Agent and the Lenders pursuant to Section 8.11) during the then current month to be less than the aggregate amount of production from Proved Producing Hydrocarbon Interests which are subject to Oil and Gas Swap Agreements during such month; provided further that the Borrower will not, nor will the Borrower permit any Restricted Subsidiary to, (x) enter into any Oil and Gas Swap Agreements except in the ordinary course of business (and not for speculative purposes), (y) enter into any Swap Agreement for speculative purposes or with a counterparty that is not an Approved Counterparty or (z) terminate, unwind, cancel or otherwise dispose of any Oil and Gas Swap Agreement except to the extent permitted by Section 9.10. For purposes of this Section 9.13, no basis swap agreement, put option, or options to purchase put options shall constitute a Swap Agreement.

Section 9.14 Ownership of Restricted Subsidiaries. Except as otherwise permitted hereunder, the Borrower shall not own, directly or indirectly, less than 100% of the issued and outstanding Equity Interests of each Restricted Subsidiary.

Section 9.15 Amendments to Organizational Documents. The Borrower shall not, and shall not permit any Restricted Subsidiary to, amend, supplement or otherwise modify (or permit to be amended, supplemented or modified) its Organization Documents in any manner that would be reasonably expected to result in a Material Adverse Effect.

ARTICLE 11
The Agents

Section 11.01 Appointment; Powers. Each of the Lenders and each Issuing Bank hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof and the other Loan Documents, together with such actions and powers as are reasonably incidental thereto.

Section 11.02 Duties and Obligations of Administrative Agent. The Administrative Agent shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing (the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law; rather, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties), (b) the

Administrative Agent shall have no duty to take any discretionary action or exercise any discretionary powers, except as provided in Section 11.03, and (c) except as expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and 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 under any other Loan Document 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 in any other Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, (v) the satisfaction of any condition set forth in ARTICLE 6 or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent or those conditions precedent expressly required to be to the Administrative Agent’s satisfaction, (vi) the existence, value, perfection or priority of any collateral security or the financial or other condition of the Borrower and its Subsidiaries or any other obligor or guarantor, or (vii) any failure by the Borrower or any other Person (other than itself) to perform any of its obligations hereunder or under any other Loan Document or the performance or observance of any covenants, agreements or other terms or conditions set forth herein or therein. For purposes of determining compliance with the conditions specified in ARTICLE 6, each Lender shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received written notice from such Lender prior to the proposed closing date specifying its objection thereto.

Section 11.03 Action by Administrative Agent. The Administrative Agent shall have no 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 in writing as directed by the Majority Lenders, the Required Lenders or the Lenders, as applicable (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) and in all cases the Administrative Agent shall be fully justified in failing or refusing to act hereunder or under any other Loan Documents unless it shall (a) receive written instructions from the Majority Lenders, the Required Lenders or the Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) specifying the action to be taken and (b) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of taking or continuing to take any such action. The instructions as aforesaid and any action taken or failure to act pursuant thereto by the Administrative Agent shall be binding on all of the Lenders. If a Default has occurred and is continuing, then the Administrative Agent shall take such action with respect to such Default as shall be directed by the requisite Lenders in the written instructions (with indemnities) described in this Section 11.03, provided that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interests of the Lenders. In no event, however, shall the Administrative Agent be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, the Loan Documents or applicable law. If a Default has occurred and is continuing, neither the Syndication Agent nor the Co-Documentation Agents shall have any obligation to perform any act in respect thereof. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Majority Lenders or the Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02), and otherwise the

Administrative Agent shall not be liable for any action taken or not taken by it in its capacity as the Administrative Agent hereunder or under any other Loan Document or under any other document or instrument referred to or provided for herein or therein or in connection herewith or therewith INCLUDING ITS OWN ORDINARY NEGLIGENCE, except for its own gross negligence or willful misconduct.

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 believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon and each of the Borrower, the Lenders and each Issuing Bank hereby waives the right to dispute the Administrative Agent’s record of such statement, except in the case of gross negligence or willful misconduct by the Administrative Agent. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. The Administrative Agent may deem and treat the payee of any Note as the holder thereof for all purposes hereof unless and until a written notice of the assignment or transfer thereof permitted hereunder shall have been filed with the Administrative Agent.

Section 11.05 Subagents. The Administrative Agent may perform any and all of its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding Sections of this ARTICLE 11 shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Section 11.06 Resignation of Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided in this Section 11.06, the Administrative Agent may resign at any time by notifying the Lenders, each Issuing Bank and the Borrower. Upon any such resignation, the Majority Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within thirty (30) days after the retiring Agent gives notice of its resignation, then the retiring Agent may, on behalf of the Lenders and each Issuing Bank, appoint a successor Agent which shall be a bank with an office in the United States, or an Affiliate of any such bank. Upon the acceptance of its appointment as Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Agent’s resignation hereunder, the provisions of this ARTICLE 11 and Section 12.03 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Agent.

Section 11.07 Agents as Lenders. Each bank serving as an 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 an Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not an Agent hereunder.

Section 11.08 No Reliance. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent, any other Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and each other Loan Document to which it is a party. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent, any other Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document, any related agreement or any document furnished hereunder or thereunder. The Agents shall not be required to keep themselves informed as to the performance or observance by the Borrower or any of its Subsidiaries of this Agreement, the Loan Documents or any other document referred to or provided for herein or to inspect the Properties or books of the Borrower or its Subsidiaries. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder, no Agent or Arranger shall have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of the Borrower (or any of its Affiliates) which may come into the possession of such Agent or any of its Affiliates. In this regard, each Lender acknowledges that ▇▇▇▇▇▇ & ▇▇▇▇▇▇ L.L.P. is acting in this transaction as special counsel to the Administrative Agent only, except to the extent otherwise expressly stated in any legal opinion or any Loan Document. Each other party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein.

Section 11.09 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Borrower or any of its Subsidiaries, the Administrative Agent (irrespective of whether the principal of any Loan 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, 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 and all other Secured Indebtedness 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 and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under Section 12.03) allowed in such judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender 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, 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.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Secured Indebtedness or the rights of any Lender or to authorize the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

Section 11.10 Authority Of Administrative Agent To Release Collateral And Liens. Each Lender and each Issuing Bank hereby authorizes the Administrative Agent to release or subordinate any Oil and Gas Property (other than, in the case of any such subordination, any Oil and Gas Property of the type described in clauses (a), (b), (c), (e) and (f) of the definition thereof evaluated in the Reserve Report used in the most recent determination of the Borrowing Base) or other collateral that is permitted to be sold, Reclassified or released or be subject to a Lien pursuant to the terms of the Loan Documents. Each Lender and each Issuing Bank hereby authorizes the Administrative Agent to execute and deliver to the Borrower, at the Borrower’s sole cost and expense, any and all releases of Liens, termination statements, assignments or other documents reasonably requested by the Borrower in connection with any sale, Reclassification or other disposition of Oil or Gas Property to the extent such sale, Reclassification or other disposition is permitted by the terms of Section 9.10 or is otherwise authorized by the terms of the Loan Documents.

Section 11.11 The Arrangers, Syndication Agent and Co-Documentation Agents. The Arrangers, the Syndication Agent and the Co-Documentation Agents shall have no duties, responsibilities or liabilities under this Agreement and the other Loan Documents other than their duties, responsibilities and liabilities in their capacity as Lenders hereunder.

The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be limited to particular notices or communications and any such approval of procedures in respect of electronic communications by any Lender or the Administrative Agent may be revoked at any time by any such Lender or by the Administrative Agent. In connection with any such revocation, if such Lender or the Administrative

Agent elects not to receive electronic communications (including those by electronic mail), then such electronic communications (including electronic mail) shall not be a valid method of delivering notices hereunder to such Person notwithstanding any provision hereof to the contrary.

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

Section 12.02 Waivers; Amendments. (a) No failure on the part of any party hereto 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, each Issuing Bank and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by 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 any Issuing Bank may have had notice or knowledge of such Default at the time.

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

(ix) change the definitions of “Required Lenders”, “Super-majority Lenders” or “Majority Lenders” or any other provisions 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 to the extent that such provision does not require the approval or consent of a Defaulting Lender, in each case without the written consent of each Lender (other than any Defaulting Lender);

provided, further, that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, any other Agent, the Swingline Lender, or any Issuing Bank hereunder or under any other Loan Document without the prior written consent of the Administrative Agent, such other Agent, the Swingline Lender or such Issuing Bank, as the case may be. Notwithstanding the foregoing, any supplement to Schedule 7.11 (Subsidiaries) shall be effective, after compliance with the requirements of Section 12.17, simply by delivering to the Administrative Agent a supplemental schedule clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders.

(b) THE BORROWER SHALL INDEMNIFY EACH AGENT, EACH ARRANGER, THE SWINGLINE LENDER, EACH ISSUING BANK AND EACH LENDER, AND EACH RELATED PARTY OF ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON BEING CALLED AN “INDEMNITEE”) AGAINST, AND DEFEND AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, PENALTIES, LIABILITIES AND RELATED EXPENSES, INCLUDING THE FEES, CHARGES AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF (i) THE EXECUTION OR DELIVERY OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY OR THEREBY, THE PERFORMANCE BY THE PARTIES HERETO OR THE PARTIES TO ANY OTHER LOAN DOCUMENT OF THEIR RESPECTIVE OBLIGATIONS HEREUNDER OR THEREUNDER OR THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREBY OR BY ANY OTHER LOAN DOCUMENT, (ii) THE FAILURE OF THE BORROWER OR ANY RESTRICTED SUBSIDIARY TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING THIS AGREEMENT, OR WITH ANY GOVERNMENTAL REQUIREMENT, (iii) ANY INACCURACY OF ANY REPRESENTATION OR ANY BREACH OF ANY WARRANTY OR COVENANT OF THE BORROWER OR ANY GUARANTOR SET FORTH IN ANY OF THE LOAN DOCUMENTS OR ANY INSTRUMENTS, DOCUMENTS OR CERTIFICATIONS DELIVERED IN CONNECTION THEREWITH, (iv) ANY LOAN OR LETTER OF CREDIT OR THE USE OF THE PROCEEDS THEREFROM, INCLUDING, WITHOUT LIMITATION, (a) ANY REFUSAL BY ANY 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, OR (b) THE PAYMENT OF A DRAWING UNDER ANY LETTER OF CREDIT NOTWITHSTANDING THE NON-COMPLIANCE, NON-DELIVERY OR OTHER IMPROPER PRESENTATION OF THE DOCUMENTS PRESENTED IN CONNECTION THEREWITH, (v) ANY OTHER ASPECT OF THE LOAN DOCUMENTS, (vi) THE OPERATIONS OF THE BUSINESS OF THE BORROWER AND ITS SUBSIDIARIES BY THE BORROWER AND ITS SUBSIDIARIES, (vii) ANY ASSERTION THAT THE LENDERS WERE NOT ENTITLED TO RECEIVE THE PROCEEDS RECEIVED PURSUANT TO THE SECURITY INSTRUMENTS, (viii) ANY ENVIRONMENTAL LAW APPLICABLE TO THE BORROWER OR ANY RESTRICTED SUBSIDIARY OR ANY OF THEIR PROPERTIES OR OPERATIONS, INCLUDING, THE PRESENCE, GENERATION, STORAGE, RELEASE, THREATENED RELEASE, USE, TRANSPORT, DISPOSAL, ARRANGEMENT OF DISPOSAL OR TREATMENT OF HAZARDOUS MATERIALS ON OR AT ANY OF THEIR PROPERTIES, (ix) ANY ENVIRONMENTAL LIABILITY RELATED IN ANY WAY TO THE BORROWER OR ANY OF ITS RESTRICTED SUBSIDIARIES, OR (x) ANY ACTUAL OR PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY AND REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO, AND SUCH INDEMNITY SHALL EXTEND TO EACH INDEMNITEE

NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF ONE OR MORE OF THE INDEMNITEES OR BY REASON OF STRICT LIABILITY IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNITEES; PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES OR RELATED EXPENSES (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, (Y) RELATE TO CLAIMS BETWEEN OR AMONG ANY OF THE LENDERS, THE ADMINISTRATIVE AGENT, THE ARRANGERS OR ANY OF THEIR AFFILIATES, SHAREHOLDERS, PARTNERS OR MEMBERS OR (Z) ARE IN RESPECT OF ANY PROPERTY FOR ANY OCCURRENCE ARISING FROM THE ACTS OR OMISSIONS OF THE ADMINISTRATIVE AGENT OR ANY LENDER DURING THE PERIOD AFTER WHICH SUCH PERSON, ITS SUCCESSORS OR ASSIGNS HAVE OBTAINED POSSESSION OF SUCH PROPERTY (WHETHER BY FORECLOSURE OR DEED IN LIEU OF FORECLOSURE, AS MORTGAGEE-IN-POSSESSION OR OTHERWISE).

(c) To the extent that the Borrower fails to pay any amount required to be paid by it to any Agent, any Arranger, the Swingline Lender, or any Issuing Bank under Section 12.03(a) or (b), each Lender severally agrees to pay to such Agent, such Arranger, the Swingline Lender, or such Issuing Bank, as the case may be, such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against such Agent, such Arranger, the Swingline Lender, or such Issuing Bank in its capacity as such.

(d) To the 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.

(e) All amounts due under this Section 12.03 shall be payable not later than 30 days after written demand therefor.

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

(b) Subject to the conditions set forth in Section 12.04(b)(ii), any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of:

(A) the Borrower, provided that no consent of the Borrower shall be required if such assignment is to a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, is to any other assignee; and

(B) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment to an assignee that is a Lender, Affiliate of a Lender or an Approved Fund of a Lender immediately prior to giving effect to such assignment.

(ii) Assignments shall be subject to the following additional conditions:

(A) except for an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, (1) in the case of an assignment to a Lender or an Affiliate of a Lender, the amount of the unused Commitment and Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $2,500,000 and the amount of the Commitment or Loans of the assigning Lender after such assignment shall not be less than $2,500,000 unless each of the Borrower and the Administrative Agent otherwise consent, provided that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing and (2) in the case of an assignment to an assignee other than a Lender or an Affiliate of a Lender, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 and the amount of the unused Commitment and Loans of the assigning Lender after such assignment shall not be less than $5,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, provided that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing;

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

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

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

(E) in no event may any Lender assign all or a portion of its rights and obligations under this Agreement to the Borrower or any Affiliate of the Borrower; and

(F) the assignee must not be a Defaulting Lender.

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

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

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in Section 12.04(b) and any written consent to such assignment required by Section 12.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 12.04(b).

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

12.04(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.08 as though it were a Lender, provided such Participant agrees to be subject to Section 4.01(c) as though it were a Lender.

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

(iii) Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each participant and the principal amounts (and related interest amounts) of each participant’s interest in the Loans or other obligations under this Agreement (the “Participant Register”). 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. No Lender shall have any obligation to disclose all or any portion of the Participant Register to the Borrower or any other Person (including the identity of any participant or any information relating to a participant’s interest in any obligations under any Loan Document) 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. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including, without limitation, any pledge or assignment to secure obligations to a Federal Reserve Bank or central bank, and this Section 12.04(d) shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

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

Section 12.05 Survival; Revival; Reinstatement. (a) All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans 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, any Issuing Bank or any Lender may have had notice or knowledge of any Default or any incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Section 5.01, Section 5.02, Section 5.03 and Section 12.03 and ARTICLE 11 shall survive and remain in full

force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the 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 Secured Indebtedness 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 Secured Indebtedness 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. (a) This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract.

(b) This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Agents and other matters 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 6.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or electronic mail shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 12.07 Severability. Any provision of this Agreement or any other Loan Document held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof or thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. If it becomes illegal for any Lender to hold or benefit from a Lien over real property pursuant to any law, such Lender shall notify the Administrative Agent and disclaim any benefit of such security interest to the extent of such illegality, but such illegality shall not invalidate or render unenforceable such Lien for the benefit of each of the other Lenders.

Section 12.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations (of whatsoever kind, including, without limitation, obligations under Swap Agreements) at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower or any Restricted Subsidiary against any of and all the

obligations of the Borrower or any Restricted Subsidiary owed to such Lender now or hereafter existing under this Agreement or any other Loan Document, irrespective of whether or not such Lender shall have made any demand under this Agreement or any other Loan Document and although such obligations may be unmatured. The rights of each Lender under this Section 12.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender or its Affiliates may have.

Section 12.09 GOVERNING LAW; JURISDICTION. (a) THIS AGREEMENT, THE NOTES AND ALL CLAIMS OR CAUSES OF ACTION (WHETHER IN CONTRACT, TORT OR OTHERWISE) THAT MAY BE BASED UPON, ARISE OUT OF OR RELATE IN ANY WAY TO THIS AGREEMENT OR THE NEGOTIATION, EXECUTION OR PERFORMANCE OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

EACH PARTY HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND DOES NOT PRECLUDE A PARTY FROM OBTAINING JURISDICTION OVER ANOTHER PARTY IN ANY COURT OTHERWISE HAVING JURISDICTION.

(c) EACH PARTY IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO IT AT THE ADDRESS SPECIFIED IN SECTION 12.01 OR SUCH OTHER ADDRESS AS IS SPECIFIED PURSUANT TO SECTION 12.01 (OR ITS ASSIGNMENT AND ASSUMPTION), SUCH SERVICE TO BECOME EFFECTIVE THIRTY (30) DAYS AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE RIGHT OF A PARTY OR ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANOTHER PARTY IN ANY OTHER JURISDICTION.

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, each 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 and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, (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 or obligations under this Agreement (provided that such Person agrees in writing to be bound by the provisions of this Section 12.11) or (ii) any actual or prospective counterparty (or its advisors) to any securitization or Swap Agreement relating to the Borrower and its obligations (provided that such Person agrees in writing to be bound by the provisions of this Section 12.11), (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section 12.11 or (ii) becomes available to the Administrative Agent, any Issuing Bank or any Lender on a nonconfidential basis from a source other than the Borrower. For the purposes of this Section 12.11, “Information” means all information received from the Borrower or any Restricted Subsidiary relating to the Borrower or any Restricted Subsidiary and their businesses, other than any such information that is available to the Administrative Agent, any Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Borrower or a Restricted Subsidiary; provided that, in the case of information received from the Borrower or any Restricted Subsidiary after the date 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.

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 State of 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 Notes, 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 Secured Indebtedness (or, to the extent that the principal amount of the Secured Indebtedness 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 Secured Indebtedness (or, to the extent that the principal amount of the Secured Indebtedness 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 actual full 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 (A) 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 (B) 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 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. The benefit of the Security Instruments and of the provisions of this Agreement relating to any collateral securing the Secured Indebtedness shall also extend to and be available to the Secured Swap Providers (on a pro rata basis in respect of any such obligations of the Borrower or any of its Restricted Subsidiaries to them) with respect to any Swap Agreement, but excluding any additional transactions or confirmations entered into (a) after such Secured Swap Provider ceases to be a Lender or an Affiliate of a Lender or (b) after assignment by a Secured Swap Provider to a Person that is not a Lender or an Affiliate of a Lender at the time of such assignment.

101

No Lender or any Affiliate of a Lender shall have any voting rights under any Loan Document as a result of the existence of obligations owed to it under any such Swap Agreements.

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 Banks 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, any Subsidiary of the Borrower, any obligor, contractor, subcontractor, supplier or materialsman) shall have any rights, claims, remedies or privileges hereunder or under any other Loan Document against the Administrative Agent, any other Agent, any Issuing Bank, the Swingline Lender, or any Lender for any reason whatsoever. There are no third party beneficiaries.

Section 12.16 Flood Insurance Regulation. Notwithstanding any provision in any Security Instrument to the contrary, in no event is any Building (as defined in the applicable Flood Insurance Regulation) or Manufactured (Mobile) Home (as defined in the applicable Flood Insurance Regulation) located in a special flood hazard area included in the definition of “Mortgaged Property”, “Collateral” or similar definition in any Security Instrument and no such Building or Manufactured (Mobile) Home shall be encumbered by any such Security Instrument.

Section 12.17 USA Patriot Act Notice. Each Lender hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act.

Section 12.18 No Fiduciary Duty. Each Agent, Lender and their respective Affiliates (collectively, solely for purposes of this paragraph, the “Banks”), may have economic interests that conflict with those of the Borrower and the Subsidiaries, their stockholders and/or their Affiliates (collectively, solely for purposes of this paragraph, the “Obligors”). The Borrower agrees that nothing in the Agreement or the Loan Documents or otherwise will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or other implied duty between any Bank, on the one hand, and any Obligor, on the other. The Borrower acknowledges and agrees that (a) the transactions contemplated by the Loan Documents (including the exercise of rights and remedies hereunder and thereunder) are arm’s-length commercial transactions between the Banks, on the one hand, and the Obligors, on the other, and (ii) in connection therewith and with the process leading thereto, (x) no Bank has assumed an advisory or fiduciary responsibility in favor of any Obligor with respect to the transactions contemplated hereby (or the exercise of rights or remedies with respect thereto) or the process leading thereto (irrespective of whether any Bank has advised, is currently advising or will advise any Obligor on other matters) or any other obligation to any Obligor except the obligations expressly set forth in the Loan Documents and (y) each Bank is acting solely as principal and not as the agent or fiduciary of any Obligor, its management, stockholders, creditors or any other Person. The Borrower acknowledges and agrees that it has consulted its own legal and financial advisors to the extent it deemed appropriate and that it is responsible for making its own independent judgment with respect to such transactions and the process leading thereto. The Borrower agrees that it will not claim that any Bank has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to any Obligor, in connection with such transaction or the process leading thereto.
