Section 1.05Accounting Terms and Determinations.

(a) Unless otherwise specified herein, all terms of an accounting or financial nature shall be construed in accordance with GAAP, as in effect from time to time;provided that if 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 such provision (or if 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as in effect and applied immediately before such change shall have become effective until such notice shall have been withdrawn or such provision amended in accordance herewith.

ARTICLE II

The Credits

Section 2.01Commitments. 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 Credit Exposure exceeding such Lender’s Commitment and (b) the total 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 2.02Loans and Borrowings.

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

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

- 31 -

(c)Minimum Amounts; Limitation on Number of Borrowings. At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $100,000 and not less than $1,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $100,000 and not less than $1,000,000;provided that an ABR Borrowing may be in an aggregate amount that is equal to the entire unused balance of the total Commitments or that is required to finance the reimbursement of an LC Disbursement as contemplated bySection 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 twelve (12) 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 a Lender shall make a written request to the Administrative Agent and the Borrower to have its Loans evidenced by a promissory note, then the Borrower shall execute and deliver a single promissory note of the Borrower in substantially the form ofExhibit A, payable to such Lender in a principal amount equal to its Maximum Credit Amount as then in effect, and otherwise duly completed. The date, amount, Type, interest rate and, if applicable, Interest Period of each Loan made by each Lender, and all payments made on account of the principal thereof, may 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;provided that the 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 2.03Requests for Borrowings. To request a Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone or by written Borrowing Request in substantially the form ofExhibit B and signed by the Borrower (a “written Borrowing Request”): (a) in the case of a Eurodollar Borrowing, not later than 1:00 p.m., New York, New York time, three (3) Business Days before the date of the proposed Borrowing or (b) in the case of an ABR Borrowing, not later than 11:00 a.m., New York, New York time, on the date of the proposed Borrowing. Each telephonic and written Borrowing Request shall be irrevocable and each telephonic Borrowing Request shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request. Each such telephonic and written Borrowing Request shall specify the following information in compliance withSection 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”;

- 32 -

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

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

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Each Borrowing Request shall constitute a representation that the amount of the requested Borrowing shall not cause the total Credit Exposures to exceed the total Commitments (i.e., the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base).

Promptly following receipt of a Borrowing Request in accordance with thisSection 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 2.04Interest 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 thisSection 2.04. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing.

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

(c)Information in Interest Election Requests. Each telephonic and written Interest Election Request shall specify the following information in compliance withSection 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 toSection 2.04(c)(iii) and(iv) shall be specified for each resulting Borrowing);

- 33 -

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

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

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

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

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

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

Section 2.05Funding 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., New York, New York time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account designated by the Borrower in the applicable Borrowing Request.

(b)Presumption of Funding by the Lenders. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing (or, in the case of any ABR Borrowing, prior to 12:00 p.m., New York, New York time, on the date of such 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 withSection 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,

- 34 -

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. No payment required and made by the Borrower under this paragraph will be subject to any break-funding payment underSection 5.02.

Section 2.06Termination 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 or the Borrowing Base is 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 $100,000 and not less than $1,000,000 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 withSection 3.04(c), the total 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 underSection 2.06(b)(i) at least three (3) 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 thisSection 2.06(b)(ii) shall be irrevocable. Any termination or reduction of the Aggregate Maximum Credit Amounts shall be permanent. Each reduction of the Aggregate Maximum Credit Amounts shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage.

Section 2.07Borrowing 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 $835,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments from time to time after the date of the initial Borrowing pursuant toSection 2.07(f),Section 2.07(g) orSection 8.12(d).

- 35 -

(b)Scheduled and Interim Redeterminations. The Borrowing Base shall be redetermined semi-annually in accordance with thisSection 2.07 (a “Scheduled Redetermination”), and, subject toSection 2.07(d), such redetermined amounts shall become effective and applicable to the Borrower, the Administrative Agent, the Issuing Banks, and the Lenders on May 1st and November 1st of each year (or, in each case, such date promptly thereafter as reasonably practicable), commencing November 1, 2013. In addition, the Borrower may, by notifying the Administrative Agent thereof, and the Administrative Agent may, at the direction of the Super Majority Lenders, by notifying the Borrower thereof, one time during each six month period, elect to cause the Borrowing Base to be redetermined between Scheduled Redeterminations (an “Interim Redetermination”) in accordance with thisSection 2.07. The Borrower may also elect to have one additional Interim Redetermination between Scheduled Redeterminations in connection with (i) any acquisition of Oil and Gas Properties having a fair market value of $10,000,000 or more or (ii) any sale or other disposition of Properties or termination of Swap Agreements in respect of commodities where the Properties so sold or Swap Agreements so terminated have a fair market value of $10,000,000 or more.

(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 toSection 8.11(a) andSection 8.11(c), and, in the case of an Interim Redetermination, pursuant toSection 8.11(b) andSection 8.11(c), and (B) such other reports, data and supplemental information, including, without limitation, the information provided pursuant toSection 8.11(c), as may, from time to time, be reasonably requested by the Super Majority 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”) equal to its good faith determination of a new Borrowing Base based upon the Engineering Reports and such other information including, without limitation, the status of title information with respect to the Oil and Gas Properties as described in the Engineering Reports and the existence of any other Debt, 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) as the Administrative Agent deems appropriate in its sole discretion and consistent with its normal oil and gas lending criteria as they exist at the particular time;provided that the aggregate value, as determined by the Administrative Agent, of (1) the Loan Parties’ proportionate share of all Oil and Gas Properties owned by Designated Partnerships and (2) all Oil and Gas Properties directly owned by Loan Parties which are not mortgaged pursuant to the Security Instruments may not exceed 20% of the aggregate value, as determined by the Administrative Agent, of all Oil and Gas Properties that are evaluated and included for purposes of determining the Borrowing Base. In no event shall the Proposed Borrowing Base exceed the Aggregate Maximum Credit Amount.

- 36 -

(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 toSection 8.11(a),Section 8.11(c) in a timely and complete manner, then on or before the first to occur of April 15th and October 15th following the date of delivery (or, in each case, such date promptly thereafter as reasonably practicable) or (2) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant toSection 8.11(a),Section 8.11(c) in a timely and complete manner, then promptly after the Administrative Agent has received complete Engineering Reports and from the Borrower and has had a reasonable opportunity to determine the Proposed Borrowing Base in accordance withSection 2.07(c)(i); and

(B) in the case of an Interim Redetermination, promptly after the Administrative Agent has received the required Engineering Reports, and has had a reasonable opportunity to determine the Proposed Borrowing Base in accordance withSection 2.07(c)(i).

(iii) Any Proposed Borrowing Base that would increase the Borrowing Base then in effect must be approved or deemed to have been approved by all of the Lenders as provided in thisSection 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 Super Majority Lenders as provided in thisSection 2.07(c)(iii). Such decisions relating to the Borrowing Base will be made by each Lender in good faith and based upon such criteria as such Lender deems appropriate in its sole discretion and consistent with its normal oil and gas lending criteria as they exist at the particular time. 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, all of the Lenders, in the case of a Proposed Borrowing Base that would increase the Borrowing Base then in effect, or the Super Majority 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 the Proposed Borrowing Base, as aforesaid, then the Proposed Borrowing Base shall become the new Borrowing Base, effective on the date specified inSection 2.07(d). If, however, at the end of such 15-day period, all of the Lenders or the Super Majority Lenders, as applicable, have not approved or deemed to have approved the Proposed Borrowing Base, as aforesaid, then the Administrative Agent shall poll the Lenders to determine the highest amount approved by all of the Lenders in the case of an amount that would increase the Borrowing Base, or the Super Majority Lenders in the case of an amount that would decrease or maintain the Borrowing Base, and such amount shall become the new Borrowing Base, effective on the date specified inSection 2.07(d).

(d)Effectiveness of a Redetermined Borrowing Base. After a redetermined Borrowing Base is approved or is deemed to have been approved by all of the Lenders or the Super Majority Lenders, as applicable, pursuant toSection 2.07(c)(iii), the Administrative Agent shall promptly (but in no event later than five (5) Business Days after such approval or deemed approval) notify the Borrower and the Lenders of the amount of the redetermined Borrowing Base (the “New Borrowing Base Notice”) and the amount of the Borrowing Base set forth therein shall become the new Borrowing Base, effective and applicable to the Borrower, the Administrative Agent, the Issuing Banks, and the Lenders:

- 37 -

(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 toSection 8.11(a) andSection 8.11(c) by the applicable date specified inSection 8.11, then on the first to occur of May 1st or November 1st following delivery of the New Borrowing Base Notice (or promptly thereafter as reasonably practicable), or (B) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant toSection 8.11(a) andSection 8.11(c) by the applicable date specified inSection 8.11, then on the Business Day next succeeding delivery of the New Borrowing Base Notice; and

(ii) in the case of an Interim Redetermination, on the Business Day next succeeding delivery of the New Borrowing Base Notice.

(e)Duration of Borrowing Base. Following delivery of the New Borrowing Base Notice, the amount of the Borrowing Base set forth in the New Borrowing Base Notice shall be the Borrowing Base until the next Scheduled Redetermination Date, the next Interim Redetermination Date or the next adjustment to the Borrowing Base, to the extent applicable, underSection 2.07(f),Section 2.07(g) orSection 8.12(d), 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.

(f)Reduction of Borrowing Base Upon Issuance of Senior Notes. In addition to the other redeterminations of the Borrowing Base provided for herein, and notwithstanding anything to the contrary contained herein, upon the issuance of any Senior Notes permitted bySection 9.02(h), the Borrowing Base then in effect shall be automatically reduced by an amount equal to the product of 0.25 multiplied by the stated principal amount of such Senior Notes (without regard to any initial issue discount), and, in each case, the Borrowing Base as so reduced shall become the new Borrowing Base immediately upon the date of such issuance, effective and applicable to the Borrower, the Administrative Agent, the Issuing Banks, and the Lenders on such date until the next redetermination or modification of the Borrowing Base pursuant to this Agreement.

(g)Reduction of Borrowing Base upon Sale of Properties, Termination of Swap Agreements or any Designated Partnership Ceasing to be a Designated Partnership. In addition to the other redeterminations of the Borrowing Base provided for herein, if at any time the aggregate Borrowing Base Value of Properties sold or disposed of, and Swap Agreements in respect of commodities terminated or otherwise monetized, pursuant toSection 9.11(d) in any period between Redeterminations of the Borrowing Base, together with (i) the Borrowing Base Value of any Oil and Gas Properties sold, transferred or otherwise disposed of by any Designated Partnership and (ii) the Borrowing Base Value of any Designated Partnership Properties evaluated in the most recent Reserve Report that are attributable to any Designated Partnership that, during such period, ceased to be a Designated Partnership for any reason (including, without limitation, as a result of being designated by the Borrower as an Undesignated Partnership pursuant toSection 8.01(p) orSection 9.20(b)), exceeds five percent (5%) of the Borrowing Base as of the last Redetermination, then, unless the Borrower has timely exercised its right to an Interim Redetermination pursuant toSection 2.07(b), to the extent available, such

- 38 -

that the Redetermination Date with respect to such Interim Redetermination may occur simultaneously with the consummation of such designation, sale or disposition (or, in the case of a Swap Agreement, termination or other monetization), the Borrowing Base shall be automatically reduced, effective immediately upon such designation, sale or disposition (or, in the case of a Swap Agreement, termination or other monetization) by an amount equal to the Borrowing Base Value of such Properties sold or disposed of (or ceasing to be Designated Partnership Properties), and Swap Agreements in respect of commodities terminated or otherwise monetized. Immediately upon such reduction, if applicable, the Borrowing Base shall be automatically redetermined by the Administrative Agent to reflect such reduction and shall become the new Borrowing Base effective and applicable to the Borrower, the Administrative Agent, the Issuing Banks and the Lenders until the next redetermination or modification of the Borrowing Base pursuant to this Agreement. Upon any such redetermination, the Administrative Agent shall promptly deliver a New Borrowing Base Notice to the Borrower and the Lenders.

Section 2.08Letters of Credit.

(a)General. Subject to the terms and conditions set forth herein, the Borrower may request an Issuing Bank to issue US dollar denominated Letters of Credit for its own account or for the account of any other Loan Party, in a form reasonably acceptable to the Administrative Agent and the applicable Issuing Bank, at any time and from time to time during the period from the Effective Date until the day which is five (5) Business Days prior to the end of the Availability Period. 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, any 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. The Existing Letters of Credit shall be deemed to have been issued hereunder as of the Effective Date. 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 an Issuing Bank and the Administrative Agent (unless otherwise agreed by the applicable Issuing Bank, not less than three (3) Business Days in advance of the requested date of issuance, amendment, renewal or extension) a notice:

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

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

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

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

- 39 -

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

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

Each notice shall constitute a representation that after giving effect to the requested issuance, amendment, renewal or extension, as applicable, (x) the LC Exposure shall not exceed the LC Commitment and (y) the total Credit Exposures shall not exceed the total Commitments (i.e., the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base). No letter of credit issued by any Issuing Bank shall be deemed to be a “Letter of Credit” issued under this Agreement unless such Issuing Bank has requested and received written confirmation from the Administrative Agent that the representations by Borrower contained in the foregoing clauses (x) and (y) are true and correct.

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 and shall guarantee the reimbursement of any Letter of Credit issued for the account of a Loan Party.

(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 (1) year after the date of the issuance of such Letter of Credit (or, in the case of any renewal, which renewal may be provided for in the initial Letter of Credit, or extension thereof, one year after such renewal or extension) and (ii) the date that is five (5) Business Days prior to the Maturity Date.

(d)Participations. By the issuance of a Letter of Credit (or an amendment to an existing Letter of Credit increasing the amount thereof) and without any further action on the part of the applicable Issuing Bank or the Lenders, each Issuing Bank 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 the applicable Issuing Bank, 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 inSection 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 thisSection 2.08(d) in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

- 40 -

(e)Reimbursement. If any Issuing Bank shall make any LC Disbursement, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than the fifth (5th) Business Day after the Borrower shall have received notice of such LC Disbursement, together with interest on the amount disbursed from and including the date of disbursement until payment in full of such disbursed amount at a varying rate per annum equal to (i) the then applicable interest rate for ABR Loans for each day such LC Disbursement shall remain outstanding through the fifth (5th) Business Day following its receipt of notice of such disbursement and (ii) thereafter, the post default rate for ABR Loans for the period from and including the sixth (6th) Business Day following the date of such disbursement to and including the date of repayment in full of such disbursed amount;provided that, unless the Borrower shall have notified the Administrative Agent to the contrary not later than 10:00 a.m., New York City time, on the Business Day next following the date on which the Borrower shall have been notified of such LC Disbursement, the Borrower will be deemed to have requested, and the Borrower does hereby request under such circumstances, in accordance withSection 2.03 that such payment be financed with an ABR Borrowing on such Business Day in an equivalent amount and, to the extent the Borrower satisfies the condition precedent to such ABR Borrowing set forth inSection 6.02(b), the Borrower’s obligation to make such payment shall be discharged with the proceeds of the requested ABR Borrowing. If the Borrower fails to make such payment when due and the Borrower is not entitled to make a Borrowing in the amount of such payment, 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 inSection 2.05 with respect to Loans made by such Lender (andSection 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the applicable Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to thisSection 2.08(e), the Administrative Agent shall distribute such payment to the applicable Issuing Bank or, to the extent that Lenders have made payments pursuant to thisSection 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 thisSection 2.08(e) to reimburse any Issuing Bank for any LC Disbursement 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 inSection 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 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 thisSection 2.08(f), constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations

- 41 -

hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Banks, nor any of their Related Parties shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Banks;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 such Issuing Bank, 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 applicable Issuing Bank may, in good faith, either accept and make payment upon such documents without responsibility for further investigation 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. Each Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by 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, 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 thisSection 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 toSection 2.08(e) to reimburse such Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i)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 thisSection 2.08(i), 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 toSection 3.04(c), then the Borrower shall deposit not later than one Business Day after receipt of notice from the Administrative Agent (or, if such notice is received after 12:00 p.m. Noon, New York, New York time, not later than the second Business Day after receipt of such notice), in a deposit account with the

- 42 -

Administrative Agent, cash collateral for the benefit of the Lenders in an amount equal to, in the case of an Event of Default, the LC Exposure, and in the case of a payment required bySection 3.04(c), the amount of such excess as provided inSection 3.04(c), as of such date plus any accrued and unpaid interest thereon;provided that such deposit shall become immediately due and payable, without demand or notice of any kind, upon the occurrence of any Event of Default with respect to any Loan Party described inSection 10.01(g) orSection 10.01(h). The Borrower hereby grants to the Administrative Agent, for the benefit of the Issuing Banks and the Lenders, a first priority 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 thisSection 2.08(i) shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which any Loan Party may now or hereafter have against any such beneficiary, the Issuing Banks, 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 other Loan Parties’ obligations under this Agreement and the other Loan Documents in a “securities account” (within the meaning of Article 8 of the UCC) over which the Administrative Agent shall have “control” (within the meaning of the UCC). Notwithstanding the foregoing, the Borrower may direct the Administrative Agent and the “securities intermediary” (within the meaning of the UCC) to invest amounts credited to the securities account, at the Borrower’s risk and expense, in Investments described inSection 9.05(c) through(f). Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse, on a pro rata basis, each Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the 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 Loan Parties under this Agreement or the other Loan Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, and the Borrower is not otherwise required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant toSection 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.

(j)Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, and any LC Exposure exists at the time a Lender becomes a Defaulting Lender, then:

(i) all or any part of such LC Exposure shall be reallocated among the non-Defaulting Lenders in accordance with their respective Applicable Percentages but only to the extent (x) the sum of all non-Defaulting Lenders’ Credit Exposures does not exceed the total of all non-Defaulting Lenders’ Commitments and (y) the conditions set forth inSection 6.02 are satisfied at such time;

- 43 -

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall within one (1) Business Day following notice by the Administrative Agent (or, if such notice is received after 12:00 p.m. Noon, New York, New York time, within two (2) Business Days following receipt of such notice) 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 inSection 2.08(i) 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 thisSection 2.08(j), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant toSection 3.05(b) with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized;

(iv) if the LC Exposure of the non-Defaulting Lenders is reallocated pursuant to thisSection 2.08(j), then the fees payable to the Lenders pursuant toSection 3.05(a) andSection 3.05(b) shall be adjusted in accordance with such non-Defaulting Lenders’ Applicable Percentages; and

(v) if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to thisSection 2.08(j), 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) underSection 3.05(a) and letter of credit fees payable underSection 3.05(b) with respect to such Defaulting Lender’s LC Exposure shall be payable to the applicable Issuing Banks until such LC Exposure is cash collateralized and/or reallocated.

Notwithstanding any provision of this Agreement to the contrary, so long as any Lender is a Defaulting Lender, 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 withSection 2.08(j), and participating interests in any such newly issued or increased Letter of Credit shall be allocated among non-Defaulting Lenders in a manner consistent withSection 2.08(j)(i) (and any Defaulting Lender shall not participate therein).

(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 withSection 3.04(b), but each prepayment must be in an amount that is an integral multiple of $100,000 and not less than $1,000,000.

Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required bySection 3.02.

(c)Mandatory Prepayments.

(i) If, after giving effect to any termination or reduction of the Aggregate Maximum Credit Amounts pursuant toSection 2.06(b), a Borrowing Base Deficiency exists, then the Borrower shall (A) prepay the Borrowings on the date of such termination or reduction in an aggregate principal amount sufficient to fully eliminate such Borrowing Base Deficiency, and (B) 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 Borrowing Base Deficiency to be held as cash collateral as provided inSection 2.08(i).

(ii) Upon any Scheduled Redetermination or Interim Redetermination of the Borrowing Base in accordance withSection 2.07(b) or any adjustment to the Borrowing Base underSection 8.12(d), if a Borrowing Base Deficiency results therefrom, then the Borrower shall, within 30 days following receipt of the New Borrowing Base Notice or notice pursuant toSection 8.12(d), as applicable, provide written notice to the Administrative Agent stating the action which the Borrower proposes to take to eliminate such Borrowing Base Deficiency, and the Borrower shall, within 30 days (or 60 days in the case of clause (C) of thisSection 3.04(c)(ii)) after its receipt of a New Borrowing Base Notice or notice pursuant toSection 8.12(d), as the case may be: (A) prepay the Loans in an amount equal to the full amount

ARTICLE IV

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

Section 4.01Payments 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 underSection 5.01,Section 5.02,Section 5.03 or otherwise) prior to 12:00 noon, New York, New York time, on the date when due, in immediately available funds, without defense, deduction, recoupment, set-off or counterclaim. Fees, once paid, shall be fully earned and shall not be refundable under any circumstances. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices specified inSection 12.01, except payments to be made directly to an Issuing Bank as expressly provided herein and except that payments pursuant toSection 5.01,Section 5.02,Section 5.03 andSection 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 prior the Termination Date, insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest, fees and other amounts then due hereunder, such funds shall be applied:first, ratably to reimbursement of expenses and indemnities provided for in this Agreement and the Security Instruments;second, to accrued interest on the Loans;third, to fees;fourth, pro rata to outstanding principal of the Loans and unreimbursed LC Disbursements; andfifth, if required by the terms of this Agreement, to serve as cash collateral to be held by the Administrative Agent to secure the LC Exposure; in each case, ratably among the parties entitled thereto in accordance with the amounts then due to such parties.

(c)Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements;provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such

- 49 -

participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of thisSection 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 or participations in LC Disbursements to any assignee or participant, other than to a Loan Party or Affiliate thereof (as to which the provisions of thisSection 4.01(c) shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law and under this Agreement, 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 4.02Presumption 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 the Issuing Banks, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Banks, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

Section 4.03Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant hereto 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. If at any time prior to the acceleration or maturity of the Loans, the Administrative Agent shall receive any payment in respect of principal of a Loan or a reimbursement of an LC Disbursement while one or more Defaulting Lenders shall be party to this Agreement, the Administrative Agent shall apply such payment first to the Borrowing(s) for which such Defaulting Lender(s) shall have failed to fund its pro rata share until such time as such Borrowing(s) are paid in full or each Lender (including each Defaulting Lender) is owed its Applicable Percentage of all Loans then outstanding. After acceleration or maturity of the Loans, all principal will be paid ratably as provided inSection 10.02(c).

Section 4.04Disposition of Proceeds. The Security Instruments contain an assignment by the Borrower and/or the other Loan Parties unto and in favor of the Administrative Agent for the benefit of the Lenders of all of the Borrower’s or each other Loan Party’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 Indebtedness and other obligations described therein and secured thereby. Notwithstanding the assignment contained in such Security Instruments, until

- 50 -

the occurrence of an Event of Default, the Administrative Agent and the Lenders agree that they will neither notify the purchaser or purchasers of such production nor take any other action to cause such proceeds to be remitted to the Administrative Agent or the Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrower or any other applicable Loan Party and 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 Loan Parties.

(ii) impose on any Lender or the London interbank market any other condition (other than Excluded Taxes) 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), in each case by an amount deemed by such Lender to be material, 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 or liquidity 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, in each case by an amount deemed by such Lender to be material, 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 would 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 and liquidity), then from time to time the Borrower will pay to such Lender or such Issuing Bank 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 an 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 inSection 5.01(a) or(b) and reasonably detailed calculations therefor shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or such Issuing Bank, as the case may be, the amount shown as due on any such certificate within 30 days after receipt thereof.

- 51 -

(d)Effect of Failure or Delay in Requesting Compensation. Failure or delay on the part of any Lender or Issuing Bank to demand compensation pursuant to thisSection 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 thisSection 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 5.02Break 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, or (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant toSection 5.05, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market.

A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to thisSection 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 30 days after receipt thereof.

Section 5.03Taxes.

(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 (a) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable

- 52 -

under thisSection 5.03(a)), the Administrative Agent, Lender or any Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (b) the Borrower or such Guarantor shall make such deductions and (c) 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. In addition, 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 thisSection 5.03) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate of the Administrative Agent, a Lender or any Issuing Bank as to the amount of such payment or liability under thisSection 5.03) shall be delivered to the Borrower and shall be conclusive absent manifest error.

(d)Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower or a Guarantor 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.

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 inSection 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.

(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.

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

- 55 -

ThisSection 5.03 shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

(i)Survival. The agreements in thisSection 5.03 shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

Section 5.04Designation of Different Lending Office. If any Lender requests compensation underSection 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 toSection 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 (a) would eliminate or reduce amounts payable pursuant toSection 5.01 orSection 5.03, as the case may be, in the future and (b) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

Section 5.05Replacement of Lenders.

- 56 -

been approved by Lenders holding 50% or more of the then outstanding Commitments, 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 inSection 12.04(b)), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment);provided that (i) 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 underSection 5.01 or payments required to be made pursuant toSection 5.03, such assignment will result in a reduction in such compensation or payments or will result in the approval of the proposed Borrowing Base.

Section 5.06Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its applicable lending office to honor its obligation to make or maintain Eurodollar Loans either generally or having a particular Interest Period hereunder, then (a) such Lender shall promptly notify the Borrower and the Administrative Agent thereof and such Lender’s obligation to make such Eurodollar Loans shall be suspended (the “Affected Loans”) until such time as such Lender may again make and maintain such Eurodollar Loans and (b) all Affected Loans which would otherwise be made by such Lender shall be made instead as ABR Loans (and, if such Lender so requests by notice to the Borrower and the Administrative Agent, all Affected Loans of such Lender then outstanding shall be automatically converted into ABR Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into) ABR Loans, all payments of principal which would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its ABR Loans;provided that the Borrower shall not be required to make any payments pursuant toSection 5.02 as a result of the conversion of any Affected Loans under thisSection 5.06.

(a) The Borrower shall, at all times during the term of this Agreement, make available for review by the Administrative Agent and the Lenders at the chief executive office of the Borrower (or such other location as the Borrower may reasonably select) during normal business hours upon reasonable advance notice to the Borrower, title information reasonably requested by the Administrative Agent covering the Oil and Gas Properties evaluated in the most recently delivered Reserve Report.

(b) In connection with the delivery of each Reserve Report required bySection 8.11(a), the Borrower shall take all commercially reasonable efforts to ensure that the Administrative Agent shall have received or have been provided reasonable access to, on or prior to the date such Reserve Report is required to be delivered pursuant toSection 8.11(a), title information (reasonably satisfactory to the Administrative Agent) as the Administrative Agent may reasonably require with respect to any Oil and Gas Properties evaluated in such Reserve Report so that the Administrative Agent shall have received, together with title information previously reviewed by the Administrative Agent, the Minimum Title Information.

To the extent that the Administrative Agent or the Super Majority Lenders are not reasonably satisfied that the Administrative Agent shall have received, together with title information previously delivered to the Administrative Agent, the Minimum Title Information with respect to Oil and Gas Properties evaluated in the most recently delivered Reserve Report free from such title defects, exceptions or omissions (other than Excepted Liens (subject to the provisos at the end of such definition) and Immaterial Title Deficiencies) after the 90-day period has elapsed, the Administrative Agent may send a notice to the Borrower and the Lenders that the then outstanding Borrowing Base shall be automatically reduced to take into account such title deficiencies, exceptions or omissions, effective immediately, by an amount as determined by the Super Majority Lenders in good faith based upon such criteria as the Super Majority Lenders deem appropriate in their sole discretion and consistent with their normal oil and gas lending criteria as they exist at the time of determination. Notwithstanding anything to the contrary contained herein, the failure of any Designated Partnership to hold record title to any Designated Partnership Property shall not be deemed to be a title defect, exception or omission with respect to such Designated Partnership Property for the purposes of thisSection 8.12 so long as (i) such Designated Partnership holds beneficial title to such Designated Partnership Property and (ii) a Loan Party holds record title to such Designated Partnership Property.

(d) In the event that any Loan Party acquires any material Property (other than any Oil and Gas Property and any Property in which a security interest is created under the Security Agreement) after the Effective Date, the Borrower shall, or shall cause such other Loan Party to, execute and deliver any Security Instruments reasonably required by the Administrative Agent in order to create a first-priority security interest and Lien in such Property.

(a) Each Lender hereby irrevocably (subject toSection 11.10) appoints, designates and authorizes the Administrative Agent to take such action on its behalf under the provisions of this Agreement and each other Loan Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Loan Document, together with such powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained elsewhere herein or in any other Loan Document, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor shall the Administrative Agent have or be deemed to have any fiduciary relationship with any Lender or participant, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Administrative Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent, any syndication agent or documentation agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, 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) Each Issuing Bank shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the documents associated therewith until such time (and except for so long) as the Administrative Agent may agree at the request of the Majority Lenders to act for such Issuing Bank with respect thereto;provided, however, that each Issuing Bank shall have all of the benefits and immunities (i) provided to the Administrative Agent in thisArticle XI with respect to any acts taken or omissions suffered by an Issuing Bank in connection with Letters of Credit issued by it or proposed to be issued by it and the application and agreements for letters of credit pertaining to the Letters of Credit as fully as if the term “Administrative Agent” as used in thisArticle XI included each Issuing Bank with respect to such acts or omissions, and (ii) as additionally provided herein with respect to each Issuing Bank.

Section 11.02Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement or any other Loan Document by or through agents, sub-agents, employees or attorneys in fact and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agent or attorney in fact that it selects in the absence of gross negligence or willful misconduct.

- 106 -

Section 11.03Default; Collateral.

(a) Upon the occurrence and continuance of a Default or Event of Default, the Lenders agree to promptly confer in order that the Majority Lenders or the Lenders, as the case may be, may agree upon a course of action for the enforcement of the rights of the Lenders; and the Administrative Agent shall be entitled to refrain from taking any action (without incurring any liability to any Person for so refraining) unless and until the Administrative Agent shall have received instructions from the Majority Lenders or the Lenders, as the case may be. All rights of action under the Loan Documents and all right to the Mortgaged Properties, if any, hereunder may be enforced by the Administrative Agent and any suit or proceeding instituted by the Administrative Agent in furtherance of such enforcement shall be brought in its name as the Administrative Agent without the necessity of joining as plaintiffs or defendants any other Lender, and the recovery of any judgment shall be for the benefit of the Lenders (and, with respect to Secured Swap Agreements and Bank Products, Affiliates, if applicable) subject to the expenses of the Administrative Agent. In actions with respect to any Property of the Borrower or any Restricted Subsidiary, the Administrative Agent is acting for the ratable benefit of each Lender (and, with respect to Secured Swap Agreements and Bank Products, Affiliates, if applicable). Any and all agreements to subordinate (whether made heretofore or hereafter) other indebtedness or obligations of Borrower to the Indebtedness shall be construed as being for the ratable benefit of each Lender (and, with respect to Secured Swap Agreements and Bank Products, Affiliates, if applicable).

(b) Each Lender authorizes and directs the Administrative Agent to enter into the Security Instruments on behalf of and for the benefit of the Lenders (and, with respect to Secured Swap Agreements and Bank Products, Affiliates, if applicable)(or if previously entered into, hereby ratifies the Administrative Agent’s (or any predecessor administrative agent’s) previously entering into such agreements and Security Instruments).

(c) Except to the extent unanimity (or other percentage set forth inSection 12.02) is required hereunder, each Lender agrees that any action taken by the Majority Lenders in accordance with the provisions of the Loan Documents, and the exercise by the Majority Lenders of the power set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of the Lenders.

(d) The Administrative Agent is hereby authorized on behalf of the Lenders, without the necessity of any notice to or further consent from any Lender, from time to time to take any action with respect to any Mortgaged Property or Security Instruments which may be necessary to perfect and maintain perfected Liens upon the Mortgaged Properties granted pursuant to the Security Instruments.

(e) The Administrative Agent shall not have any obligation whatsoever to any Lender or to any other Person to assure that the Mortgaged Property exists or is owned (whether in fee or by leasehold) by the Person purporting to own it or is cared for, protected, or insured or has been encumbered or that the Liens granted to the Administrative Agent (or any predecessor administrative agent) herein or pursuant thereto have been properly or sufficiently or lawfully created, perfected, protected, or enforced, or are entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue

- 107 -

exercising, any of the rights granted or available to the Administrative Agent in thisSection 11.03 or in any of the Security Instruments; IT BEING UNDERSTOOD AND AGREED THAT IN RESPECT OF THE MORTGAGED PROPERTY, OR ANY ACT, OMISSION, OR EVENT RELATED THERETO, THE ADMINISTRATIVE AGENT MAY ACT IN ANY MANNER IT MAY DEEM APPROPRIATE, IN ITS SOLE DISCRETION, GIVEN THE ADMINISTRATIVE AGENT’S OWN INTEREST IN THE MORTGAGED PROPERTY AS ONE OF THE LENDERS AND THAT THE ADMINISTRATIVE AGENT SHALL HAVE NO DUTY OR LIABILITY WHATSOEVER TO ANY LENDER (AND, WITH RESPECT TO SECURED SWAP AGREEMENTS AND BANK PRODUCTS, AFFILIATES), OTHER THAN TO ACT WITHOUT GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

(f) The Lenders hereby irrevocably authorize the Administrative Agent, at its option and in its discretion, to release any Lien granted to or held by the Administrative Agent upon any Mortgaged Property: (A) constituting property in which neither Borrower nor any Restricted Subsidiary owned an interest at the time the Lien was granted or at any time thereafter; (B) constituting property leased to the Borrower or a Restricted Subsidiary under a lease which has expired or been terminated in a transaction permitted under the Loan Documents or is about to expire and which has not been, and is not intended by the Borrower or such Restricted Subsidiary to be, renewed; or (C) consisting of an instrument or other possessory collateral evidencing Debt or other obligations pledged to the Administrative Agent (for the benefit of the Lenders), if the Debt or obligations evidenced thereby has been paid in full or otherwise superseded. In addition, the Lenders irrevocably authorize the Administrative Agent to release Liens upon Mortgaged Property as contemplated herein and in the other Loan Documents, or if approved, authorized, or ratified in writing by the requisite Lenders. Upon request by the Administrative Agent at any time, the Lenders will confirm in writing the Administrative Agent’s authority to release particular types or items of Mortgaged Property pursuant to thisSection 11.03.

(g) In furtherance of the authorizations set forth in thisSection 11.03, each Lender hereby irrevocably appoints the Administrative Agent as its attorney-in-fact, with full power of substitution, for and on behalf of and in the name of each such Lender (i) to enter into Security Instruments (including, without limitation, any appointments of substitute trustees under any Security Instruments), (ii) to take action with respect to the Mortgaged Property and Security Instruments to perfect, maintain, and preserve the Lenders’ Liens, and (iii) to execute instruments of release or to take other action necessary to release Liens upon any Mortgaged Property to the extent authorized herein or in the other Loan Documents. This power of attorney shall be liberally, not restrictively, construed so as to give the greatest latitude to the Administrative Agent’s power, as attorney, relative to the Mortgaged Property matters described in thisSection 11.03. The powers and authorities herein conferred on the Administrative Agent may be exercised by the Administrative Agent through any Person who, at the time of the execution of a particular instrument, is an officer of the Administrative Agent (or any Person acting on behalf of the Administrative Agent pursuant to a valid power of attorney). The power of attorney conferred by thisSection 11.03(g) to the Administrative Agent is granted for valuable consideration and is coupled with an interest and is irrevocable so long as the Indebtedness, or any part thereof, shall remain unpaid or the Lenders are obligated to make any Loan or issue any Letter of Credit under the Loan Documents.

- 108 -

Section 11.04Liability of Administrative Agent. NO RELATED PARTY OF THE ADMINISTRATIVE AGENT SHALL (A) BE LIABLE FOR ANY ACTION TAKEN OR OMITTED TO BE TAKEN BY ANY OF THEM UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (EXCEPT FOR ITS OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT IN CONNECTION WITH ITS DUTIES EXPRESSLY SET FORTH HEREIN), or (b) be responsible in any manner to any Lender or participant for any recital, statement, representation or warranty made by the Borrower or any Restricted Subsidiary or any officer thereof, contained herein or in any other Loan Document, or in any certificate, report, statement or other document referred to or provided for in, or received by the Administrative Agent under or in connection with, this Agreement or any other Loan Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document, or for the creation, perfection or priority of any Liens purported to be created by any of the Loan Documents, or the validity, genuineness, enforceability, existence, value or sufficiency of any collateral security, or to make any inquiry respecting the performance by the Borrower of its obligations hereunder or under any other Loan Document, or for any failure of the Borrower or any Restricted Subsidiary or any other party to any Loan Document to perform its obligations hereunder or thereunder. No Related Party of the Administrative Agent shall be under any obligation to any Lender or Participant to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of the Borrower or any Restricted Subsidiary or any Affiliate thereof.

Section 11.05Reliance by Administrative Agent.

(a) The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, communication, signature, resolution, representation, notice, consent, certificate, affidavit, letter, telegram, facsimile, electronic mail, or telephone message, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel (including counsel to the Borrower or any Restricted Subsidiary), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under any Loan Document unless it shall first receive such advice or concurrence of the Majority Lenders as it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement or any other Loan Document in accordance with a request or consent of the Majority Lenders or all the Lenders, if required hereunder, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and Participants. Where this Agreement expressly permits or prohibits an action unless the Majority Lenders or Super Majority Lenders otherwise determine, the Administrative Agent shall, and in all other instances, the Administrative Agent may, but shall not be required to, initiate any solicitation for the consent or a vote of the requisite Lenders.

- 109 -

(b) For purposes of determining compliance with the conditions specified inSection 6.01, each Lender that has funded its Applicable Percentage of the initial Loan on the Effective Date (or, if there is no Loan made on such date, each Lender other than the Lenders who gave written objection to the Administrative Agent prior to such date) shall be deemed to have consented to, approved or accepted, or to be satisfied with, each document or other matter either sent by the Administrative Agent to such Lender (or otherwise made available for such Lender on SyndTrak Online, DXSyndicate™ or any similar website) for consent, approval, acceptance or satisfaction, or required hereunder to be consented to or approved by or acceptable or satisfactory to a Lender.

Section 11.06Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, except with respect to defaults in the payment of principal, interest and fees required to be paid to the Administrative Agent for the account of the Lenders, unless the Administrative Agent shall have received written notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default.” The Administrative Agent will notify the Lenders of its receipt of any such notice. The Administrative Agent shall take such action with respect to such Default or Event of Default as may be directed by the Majority Lenders in accordance with this Agreement;provided, however, that unless and until the Administrative Agent has received any such direction, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable or in the best interest of the Lenders.

Section 11.07Credit Decision; Disclosure of Information by Administrative Agent. Each Lender acknowledges that no Related Party of the Administrative Agent has made any representation or warranty to it, and that no act by the Administrative Agent hereinafter taken, including any consent to and acceptance of any assignment or review of the affairs of the Borrower or any Restricted Subsidiary or any Affiliate thereof, shall be deemed to constitute any representation or warranty by any Related Party of the Administrative Agent to any Lender as to any matter, including whether Related Parties of the Administrative Agent have disclosed material information in their possession. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon any Related Party of the Administrative Agent and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrower, any Guarantor and their respective Subsidiaries, and all applicable bank or other regulatory laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit to the Borrower hereunder. Each Lender also represents that it will, independently and without reliance upon any Related Party of the Administrative Agent and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrower and the other Loan Parties. In this regard, each Lender acknowledges that Vinson & Elkins L.L.P. is acting in this transaction as counsel to the Administrative Agent. 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. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent herein, the Administrative Agent shall not have any duty or responsibility

- 110 -

to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of any of the Loan Parties or any of their respective Affiliates which may come into the possession of any Related Party of the Administrative Agent.

Section 11.08Indemnification of Agents. WHETHER OR NOT THE TRANSACTIONS CONTEMPLATED HEREBY ARE CONSUMMATED, THE LENDERS SHALL INDEMNIFY UPON DEMAND EACH RELATED PARTY OF THE ADMINISTRATIVE AGENT (TO THE EXTENT NOT REIMBURSED BY OR ON BEHALF OF THE BORROWER AND WITHOUT LIMITING THE OBLIGATION OF THE BORROWER TO DO SO), IN ACCORDANCE WITH THEIR RESPECTIVE APPLICABLE PERCENTAGES, AND HOLD HARMLESS EACH RELATED PARTY OF THE ADMINISTRATIVE AGENT FROM AND AGAINST ANY AND ALL INDEMNIFIED LIABILITIES INCURRED BY IT (INCLUDING SUCH RELATED PARTY OF THE ADMINISTRATIVE AGENT’S OWN NEGLIGENCE);PROVIDED, HOWEVER, THAT NO LENDER SHALL BE LIABLE FOR THE PAYMENT TO ANY RELATED PARTY OF THE ADMINISTRATIVE AGENT OF ANY PORTION OF SUCH INDEMNIFIED LIABILITIES RESULTING FROM SUCH PERSON’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT;provided, however, that no action taken in accordance with the directions of the Majority Lenders shall be deemed to constitute gross negligence or willful misconduct for purposes of thisSection 11.08. Without limitation of the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its ratable share of any costs or out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Loan Document, or any document contemplated by or referred to herein, to the extent that the Administrative Agent is not reimbursed for such expenses by or on behalf of the Borrower. The undertaking in thisSection 11.08 shall survive termination of the Commitments, the payment of all Indebtedness hereunder and the resignation or replacement of the Administrative Agent.

Section 11.09Administrative Agent in its Individual Capacity. Wells Fargo and its Affiliates may make loans to, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with the Borrower and its Affiliates as though Wells Fargo were not the Administrative Agent or an Issuing Bank hereunder and without notice to or consent of the Lenders. The Lenders acknowledge that, pursuant to such activities, Wells Fargo or its Affiliates may receive information regarding the Borrower or its Affiliates (including information that may be subject to confidentiality obligations in favor of the Borrower or such Affiliate) and acknowledge that the Administrative Agent shall be under no obligation to provide such information to them. With respect to its Loans, Wells Fargo shall have the same rights and powers under this Agreement as any other Lender and may exercise such rights and powers as though it were not the Administrative Agent or an Issuing Bank, and the terms “Lender” and “Lenders” include Wells Fargo in its individual capacity.

- 111 -

Section 11.10Successor Administrative Agent and Issuing Bank. The Administrative Agent or an Issuing Bank may resign at any time upon 30 days’ notice to the Lenders with a copy of such notice to the Borrower. If the Administrative Agent or Issuing Bank resigns under this Agreement, the Majority Lenders shall appoint from among the Lenders a successor administrative agent or issuing bank for the Lenders which successor administrative agent or issuing bank shall be consented to by the Borrower at all times other than during the existence of an Event of Default (which consent of the Borrower shall not be unreasonably withheld, delayed or conditioned). If no successor administrative agent or issuing bank is appointed prior to the effective date of the resignation of the Administrative Agent or Issuing Bank, the Administrative Agent may appoint, after consulting with the Lenders and, so long as no Event of Default has occurred which is continuing, upon written approval of the Borrower (which approval of the Borrower shall not be unreasonably withheld, delayed or conditioned), a successor administrative agent and/or issuing bank from among the Lenders. Upon the acceptance of its appointment as successor administrative agent and/or issuing bank hereunder, such successor administrative agent and/or issuing bank shall succeed to all the rights, powers and duties of the retiring Administrative Agent or Issuing Bank and the term “Administrative Agent” and “Issuing Bank” shall mean such successor administrative agent or issuing bank and the retiring Administrative Agent’s or Issuing Bank’s appointment, powers and duties as Administrative Agent or Issuing Bank shall be terminated. The resigning Issuing Bank shall remain the Issuing Bank with respect to any Letters of Credit outstanding on the effective date of its resignation and the provisions affecting such Issuing Bank with respect to Letters of Credit shall inure to the benefit of the resigning Issuing Bank until the termination of all such Letters of Credit. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of thisArticle XI andSections 12.03 and12.05 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. If no successor administrative agent has accepted appointment as Administrative Agent by the date which is 30 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Majority Lenders appoint a successor agent as provided for above.

Section 11.11Syndication Agent; Other Agents; Arrangers. None of the Lenders or other Persons identified on the facing page or signature pages of this Agreement as a “syndication agent,” as a “documentation agent,” any other type of agent (other than the Administrative Agent), “arranger,” or “bookrunner” shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, none of the Lenders so identified shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any of the Lenders so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

Section 11.12Administrative Agent May File Proof 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 Restricted Subsidiary, the Administrative Agent (irrespective of whether the principal of any Loan or LC Exposure shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise

- 112 -

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, LC Exposures and all other 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, the Issuing Banks and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the Issuing Banks and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the Issuing Banks and the Administrative Agent underSection 12.03) allowed in such judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender and Issuing Bank to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders and Issuing Banks, 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 underSection 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 or Issuing Bank any plan of reorganization, arrangement, adjustment or composition affecting the 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 11.13Secured Swap Agreements. To the extent any Affiliate of a Lender is a party to a Secured Swap Agreement with the Borrower or any of the Restricted Subsidiaries and thereby becomes a beneficiary of the Liens pursuant to any Security Instrument, such Affiliate of a Lender shall be deemed to appoint the Administrative Agent its nominee and agent to act for and on behalf of such Affiliate in connection with such Security Instruments and to be bound by the terms of thisArticle XI and the other provisions of this Agreement.

Section 11.14Bank Product Obligations. To the extent any Affiliate of a Lender provides any Bank Products and thereby becomes a beneficiary of the Liens pursuant to any Security Instrument, such Affiliate of a Lender shall be deemed to appoint the Administrative Agent its nominee and agent to act for and on behalf of such Affiliate in connection with such Security Instruments and to be bound by the terms of thisArticle XI and the other provisions of this Agreement.

Section 11.15Intercreditor Agreement. The Lenders hereby authorize the Administrative Agent to enter into the Intercreditor Agreement and to amend such agreement in accordance with the provisions of Section 12.02. Each Lender (by receiving the benefits thereunder and of the Mortgaged Property pledged pursuant to the Security Instruments) agrees that the terms of the Intercreditor Agreement shall be binding on such Lender and its successors and assigns, as if it were a party thereto.

Section 12.02Waivers; Amendments.

(a) No failure on the part of the Administrative Agent, any Issuing Bank or any Lender to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege, or any abandonment or discontinuance of steps to enforce such right, power or privilege, under any of the Loan Documents shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under any of the Loan Documents preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies of the Administrative Agent, the Issuing Banks and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be permitted bySection 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 the issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any Issuing Bank or any Lender may have had notice or knowledge of such Default at the time.

(b) Subject toSection 12.04(b)(ii)(E)(4), 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 Loan Parties party thereto 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

(i) increase the Maximum Credit Amount of any Lender without the written consent of such Lender,

(ii) increase the Borrowing Base without the written consent of all Lenders (other than any Defaulting Lender and any Affiliate Lender) or decrease or maintain the Borrowing Base without the consent of the Super Majority Lenders,

(iii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender directly and adversely affected thereby; provided that the consent of an Affiliate Lender for any such reduction shall not be required if such reduction is proportionately applicable to each Lender (including such Affiliate Lender),

- 115 -

(iv) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Termination Date without the written consent of each Lender directly and adversely affected thereby; provided that the consent of an Affiliate Lender for any such postponement, reduction, extension or waiver shall not be required if such postponement, reduction, extension or waiver is proportionately applicable to each Lender (including such Affiliate Lender),

(v) changeSection 4.01(b) orSection 4.01(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender adversely affected thereby; provided that the consent of an Affiliate Lender for any such change shall not be required if such change is proportionately applicable to each Lender (including such Affiliate Lender),

(vi) release any Guarantor (except as set forth in the Guaranty Agreement), release all or substantially all of the collateral, or reduce the percentage set forth in the definition of Required Mortgage Value to less than 80%, without the written consent of each Lender (other than any Defaulting Lender and any Affiliate Lender), or

(vii) change any of the provisions of thisSection 12.02(b) or the definitions of “Super Majority Lenders” or “Majority Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or under any other Loan Documents or make any determination or grant any consent hereunder or any other Loan Documents, without the written consent of each Lender directly and adversely affected thereby;

provided further, that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent or any Issuing Bank hereunder or under any other Loan Document without the prior written consent of the Administrative Agent or such Issuing Bank, as the case may be. Notwithstanding the foregoing, any supplement toSchedule 7.15 (Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental schedule clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders.

Section 12.03Expenses, Indemnity; Damage Waiver.

(a) The Borrower shall pay (i) all reasonable and documented out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including, without limitation, the reasonable fees, charges and disbursements of counsel and other outside consultants for the Administrative Agent, the reasonable travel, photocopy, mailing, courier, telephone and other similar expenses, and the cost of environmental audits and surveys and appraisals, in connection with the syndication of the credit facilities provided for herein, the preparation, negotiation, execution, delivery and administration (both before and after the execution hereof and including advice of counsel to the Administrative Agent as to the rights and duties of the Administrative Agent and the Lenders with respect thereto) of this Agreement and the other Loan Documents and any amendments, modifications or waivers of or consents related to the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated),

(A) the Borrower (such consent not to be unreasonably withheld, conditioned or delayed),provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund (as defined below) or, if an Event of Default has occurred and is continuing, any other Person; and

For the purposes of thisSection 12.04, “Approved Fund” means a Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) a Person or an Affiliate of a Person that administers or manages a Lender.

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) below, 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 ofSection 5.01,Section 5.02,Section 5.03 andSection 12.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with thisSection 12.04(b) shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance withSection 12.04(c).

- 121 -

(iv) The Administrative Agent, acting solely 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 Exposures owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Issuing Banks 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.

(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 inSection 12.04(b), and any written consent to such assignment required bySection 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 thisSection 12.04(b).

(c) (i) Any Lender may, without the consent of the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (each 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, the Issuing Banks 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 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 may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that (1) requires the consent of each Lender directly affected thereby pursuant toSection 12.02(b) and (2) directly affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits ofSection 5.01,Section 5.02, andSection 5.03 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant toSection 12.04(b). To the extent permitted by law, each Participant also shall be entitled to the benefits ofSection 12.08 as though it were a Lender,provided such Participant shall be subject toSection 4.01 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in

- 122 -

registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(ii) A Participant shall not be entitled to receive any greater payment underSection 5.01 orSection 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. Any Participant that is a Foreign Lender shall not be entitled to the benefits ofSection 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).

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

(e) Notwithstanding the foregoing, any Lender may grant to a Conduit Lender the option to provide to the Borrower all or any part of any Loan that a Lender would be required to make, and any Conduit Lender may assign any or all of the Loans it may have funded hereunder to its designating Lender, in each case, without the consent of the Borrower or the Administrative Agent and without regard to the limitations set forth inSection 12.04(b). Each of the Borrower, each Lender and the Administrative Agent hereby confirms that it will not institute against a Conduit Lender or join any other Person in instituting against a Conduit Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding under any state bankruptcy or similar law, for one year and one day after the payment in full of the latest maturing commercial paper note issued by such Conduit Lender;provided, however, that each Lender designating any Conduit Lender hereby agrees to indemnify, save and hold harmless each other party hereto for any loss, cost, damage or expense arising out of its inability to institute such a proceeding against such Conduit Lender during such period of forbearance.

Section 12.05Survival; Revival; Reinstatement.

(a) All covenants, agreements, representations and warranties made by the Borrower herein and by the Loan Parties 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 Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and

- 123 -

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 ofSection 5.01,Section 5.02,Section 5.03 andSection 12.03 andArticle XI 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 any payment by or on behalf of the Borrower is made to the Administrative Agent, any Issuing Bank or any Lender, and such payment or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Administrative Agent, any Issuing Bank or any Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any bankruptcy or other laws for the relief of debtors or otherwise, then to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made.

Section 12.06Counterparts; 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 Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof and thereof. This Agreement and the other Loan Documents represent the final agreement among the parties hereto and thereto and may not be contradicted by evidence of prior, contemporaneous or subsequent oral agreements of the parties. There are no unwritten oral agreements between the parties.

(c) Except as provided inSection 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 email (in .pdf or similar format) or telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 12.07Severability. 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.

- 124 -

Section 12.08Right of Setoff. If an Event of Default underSection 10.01(a) orSection 10.01(b) 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 limitations 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. Such Lender shall promptly notify the Borrower after any such set off and application made by such Lender, but the failure to give such notice will not affect the validity of such set off and application. The rights of each Lender under thisSection 12.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender or its Affiliates may have.

Each Lender acknowledges that information furnished to it pursuant to this Agreement or the other Loan Documents may include material non-public information concerning the Borrower and its Affiliates and their related parties or their respective securities, and confirms that it has developed compliance procedures regarding the use of material non-public information and that it will handle such material non-public information in accordance with those procedures and applicable law, including Federal and state securities laws.

All information, including requests for waivers and amendments, furnished by the Borrower or the Administrative Agent pursuant to, or in the course of administering, this Agreement or the other Loan Documents will be syndicate-level information, which may contain material non-public information about the Borrower and its Affiliates and their related parties or their respective securities.

Section 12.12Interest Rate Limitation. It is the intention of the parties hereto that each Lender shall conform strictly to usury laws applicable to it.

counterparties to any Secured Swap Agreement with the Borrower or any of the Restricted Subsidiaries on a pro rata basis in respect of any obligations of the Borrower or any of the Restricted Subsidiaries which arise under any such Secured Swap Agreement while such Person or its Affiliate is a Lender.
