(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.

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

(e) Loans and Borrowings under the Existing Credit Agreement. On the Effective Date (or as soon as practicable with respect to (iii)):

(i) the Borrower shall pay all accrued and unpaid commitment fees, break funding fees under Section 5.02 and all other fees that are outstanding under the Existing Credit Agreement for the account of each “Lender” under the Existing Credit Agreement;

(ii) each “ABR Loan” and “Eurodollar Loan” outstanding under the Existing Credit Agreement shall be deemed to be amended and restated with the proceeds of a new ABR Loan or Eurodollar Loan, as applicable, and continued as existing Loans under this Agreement and not as a novation;

(iii) the Administrative Agent shall use reasonable efforts to cause each “Lender” under the Existing Credit Agreement to deliver to the Borrower as soon as practicable after the Effective Date the Note issued by the Borrower to it under the Existing Credit Agreement, marked “canceled” or otherwise similarly defaced;

(iv) any letters of credit outstanding under the Existing Credit Agreement shall be deemed issued under this Agreement; and

any such obligations and liabilities and that this Agreement amend and restate in its entirety the Existing Credit Agreement and re-evidence the obligations of the Borrower outstanding thereunder.

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.

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

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

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

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

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

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

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 continued as a Eurodollar Loan having an Interest Period of one-month. Notwithstanding any contrary provision hereof, (i) if an Event of Default has occurred and is continuing: (A) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing (and any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective) and (B) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto and (ii) if a Borrowing Base Deficiency exists: (A) outstanding Borrowings may not be converted or continued as Eurodollar Borrowings unless, after giving effect thereto and to the conversion or continuation of Borrowings to ABR Borrowings, there are ABR Borrowings in an amount no less than the amount of such Borrowing Base Deficiency and (B) unless sooner repaid, any Eurodollar Borrowing in excess of the Borrowing Base shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

Section 2.05 Funding of Borrowings.

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

(b) Presumption of Funding by the Lenders. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.05(a) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing. If the

Credit Agreement

US 793906v.7

Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period.

Section 2.06 Termination and Reduction of Aggregate Maximum Credit Amounts.

(a) Scheduled Termination of Commitments. Unless previously terminated, the Commitments shall terminate on the Maturity Date. If at any time the Aggregate Maximum Credit Amounts 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 $500,000 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 with Section 3.04(c), the total Revolving Credit Exposures would exceed the total Commitments.

(ii) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Aggregate Maximum Credit Amounts under Section 2.06(b)(i) at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section 2.06(b)(ii) shall be irrevocable; provided that a notice of reduction or termination of the Aggregate Maximum Credit Amounts delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities or other securities offerings, in which case such notice may be revoked by the Borrower if such condition is not satisfied. Any termination or reduction of the Aggregate Maximum Credit Amounts shall be permanent and may not be reinstated. Each reduction of the Aggregate Maximum Credit Amounts shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage.

Section 2.07 Borrowing Base.

(a) Initial Borrowing Base. For the period from and including the Effective Date to but excluding the first Scheduled Redetermination Date thereafter, the amount of the Borrowing Base shall be $2,500,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments from time to time pursuant to Section 2.07(e), Section 2.07(f), Section 8.12(c), or Section 9.11(d).

(b) Scheduled and Interim Redeterminations. Subject to Section 2.07(d), the Borrowing Base shall be redetermined (a “Scheduled Redetermination”) on April 1st and October 1st of each year, commencing October 1, 2011. In addition, either the Borrower or the

Credit Agreement

US 793906v.7

Administrative Agent, at the direction of the Super-Majority Tier I Lenders, may, once during each calendar year, each elect to cause the Borrowing Base to be redetermined between Scheduled Redeterminations (an “Interim Redetermination”) in accordance with this Section 2.07. The Borrower shall have the right, once during each calendar year, to initiate an Interim Redetermination in addition to the one otherwise provided in this Section 2.07(b) upon the proposed acquisition of Proved Developed Producing Properties whose purchase price is greater than 10% of the Borrowing Base, provided such Interim Redetermination is in accordance with this Section 2.07.

(i) Each Scheduled Redetermination and each Interim Redetermination shall be effectuated as follows: Upon receipt by the Administrative Agent of (A) the applicable Reserve Report and the Reserve Report Certificate related thereto and (B) such other reports, data and supplemental information, including, without limitation, the information provided pursuant to Section 8.11(c) and the list of Swap Agreements per Section 8.01(d), as may, from time to time, be reasonably requested by the Majority Tier I Lenders (the Reserve Report, such certificate and such other reports, data and supplemental information being the “Engineering Reports”), the Administrative Agent shall evaluate the information contained in the Engineering Reports and shall, in good faith, propose a new Borrowing Base (the “Proposed Borrowing Base”) based upon such information and such other information (including, without limitation, the status of title information with respect to the Oil and Gas Properties as described in the Engineering Reports and the existence of any other Debt) as the Administrative Agent, in good faith, deems appropriate and consistent with its normal oil and gas lending criteria as it exists at the particular time. In addition, the Administrative Agent will summarize the Swap PV of such Swap Agreements as of the date of the Proposed Borrowing Base Notice.

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

(A) in the case of a Scheduled Redetermination (1) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.11(a) and (c) in a timely and complete manner, then on or before the March 15th and September 15th of such year following the date of delivery of such Engineering Report or (2) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.11(a) and (c) in a timely and complete manner, then promptly after the Administrative Agent has received complete Engineering Reports from the Borrower and has had a reasonable opportunity to determine the Proposed Borrowing Base in accordance with Section 2.07(c)(i) and in any event, within fifteen (15) days after the Administrative Agent has received the required Engineering Report; and

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

Credit Agreement

US 793906v.7

(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 Tier I Lenders as provided in this Section 2.07(c)(iii); and any Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect must be approved or be deemed to have been approved by the Super-Majority Tier I Lenders as provided in this Section 2.07(c)(iii). Upon receipt of the Proposed Borrowing Base Notice, each Lender shall have fifteen (15) days to agree with the Proposed Borrowing Base or disagree with the Proposed Borrowing Base by proposing an alternate Borrowing Base. If at the end of such fifteen (15) days, any Lender has not communicated its approval or disapproval in writing to the Administrative Agent, such silence shall be deemed to be an approval of the Proposed Borrowing Base. If, at the end of such 15-day period, all of the Tier I Lenders, in the case of a Proposed Borrowing Base that would increase the Borrowing Base then in effect, or the Super-Majority Tier I Lenders, in the case of a Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect, have approved or deemed to have approved, as aforesaid, then the Proposed Borrowing Base shall become the new Borrowing Base effective on the date specified in Section 2.07(d). If, however, at the end of such 15-day period, all of the Tier I Lenders or the Super-Majority Tier I Lenders, as applicable, have not approved or deemed to have approved, as aforesaid, then the Administrative Agent shall poll the Tier I Lenders to ascertain the highest Borrowing Base then acceptable to a number of Tier I Lenders sufficient to constitute the Super-Majority Tier I Lenders and, so long as such amount does not increase the Borrowing Base then in effect, such amount shall become the new Borrowing Base effective on the date specified in Section 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 Tier I Lenders or the Super-Majority Tier I Lenders, as applicable, pursuant to Section 2.07(c)(iii), the Administrative Agent shall notify the Borrower and the Lenders (the “New Borrowing Base Notice”) of the amount of the redetermined Borrowing Base, and such amount shall become the new Borrowing Base effective and applicable to the Borrower, the Administrative Agent, each Issuing Bank and the Lenders:

(i) in the case of a Scheduled Redetermination, (A) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.11(a) and (c) in a timely and complete manner, then on the April 1st or October 1st, as applicable, following delivery of the New Borrowing Base Notice, or (B) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.11(a) and (c) in a timely and complete manner, then on the Business Day next succeeding 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.

Such amount shall then become the Borrowing Base until the next Scheduled Redetermination Date, the next Interim Redetermination date or the next adjustment to the Borrowing Base under Section 2.07(e), Section 2.07(f), Section 8.12(c) or Section 9.11(d), whichever occurs first.

Credit Agreement

US 793906v.7

(e) Reduction of Borrowing Base Upon Issuance of Funded Debt. Upon the issuance of any Funded Debt or any Permitted Refinancing Debt in accordance with Section 9.02(f), the Borrowing Base then in effect shall be reduced by an amount equal to 0.25 multiplied by (i) in the case of Funded Debt constituting Permitted Refinancing Debt, the portion of the stated principal amount of such Funded Debt that exceeds the original principal amount of the refinanced Funded Debt and (ii) in the case of all other Funded Debt, the stated principal amount of such Funded Debt (without regard to any original issue discount), and 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, each Issuing Bank and the Lenders on such date until the next redetermination or modification thereof hereunder.

(f) Reduction of Borrowing Base Upon Termination of Hedge Positions. If the Borrower or any Subsidiary shall terminate or create any off-setting positions in respect of any hedge positions upon which the Lenders relied in determining the most recent Borrowing Base, and the aggregate Swap PV of all such terminations and/or offsetting positions exceeds, during any period between redeterminations of the Borrowing Base, the lesser of (a) $50,000,000 or (b) 3% of the then effective Borrowing Base, then the Borrowing Base shall be simultaneously reduced in an amount equal to 65% of such aggregate Swap PV.

Section 2.08 Letters of Credit.

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

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall deliver as permitted by Section 12.01(a) (or transmit by electronic communication, if arrangements for doing so have been approved by the Issuing Bank) to any Issuing Bank and the Administrative Agent (not less than three (3) Business Days in advance of the requested date of issuance, amendment, renewal or extension) a notice:

(i) requesting the issuance of a Letter of Credit or identifying the Letter of Credit issued by such Issuing Bank to be amended, renewed or extended;

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

Credit Agreement

US 793906v.7

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

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

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

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

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

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

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) unless satisfactorily collateralized in the applicable Issuing Bank’s reasonable opinion, the date eighteen months after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is five Business Days prior to the Maturity Date.

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

Credit Agreement

US 793906v.7

Default, the existence of a Borrowing Base Deficiency or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If any Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit issued by such Issuing Bank, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 1:00 p.m., Houston time, on the third day after such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 9:00 a.m., Houston time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 1:00 p.m., Houston time, on (i) the third day after the Borrower receives such notice, if such notice is received prior to 9:00 a.m., Houston time, on the day of receipt, or (ii) the Business Day immediately following the third day after the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that if such LC Disbursement is not less than $1,000,000, the Borrower shall, subject to the conditions to Borrowing set forth herein, be deemed to have requested, and the Borrower does hereby request under such circumstances, that such payment be financed with a Eurodollar Borrowing with an Interest Period of one month in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting Eurodollar Borrowing. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.05 with respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank that issued such Letter of Credit the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this Section 2.08(e), the Administrative Agent shall distribute such payment to the Issuing Bank that issued such Letter of Credit or, to the extent that Lenders have made payments pursuant to this Section 2.08(e) to reimburse such Issuing Bank, then to such Lenders and such Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this Section 2.08(e) to reimburse any Issuing Bank for any LC Disbursement (other than the funding of ABR Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement. Any LC Disbursement not reimbursed by the Borrower or funded as a Loan prior to 1:00 p.m., Houston time, shall bear interest for such day at the Alternate Base Rate plus the Applicable Margin.

(f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in Section 2.08(e) shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit, any Letter of Credit Agreement or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any

Credit Agreement

US 793906v.7

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

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

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

Credit Agreement

US 793906v.7

payment by any Lender pursuant to Section 2.08(e) to reimburse such Issuing Bank shall be for the account of such Lender to the extent of such payment.

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

(j) Cash Collateralization. If (i) any Event of Default shall occur and be continuing and the Borrower receives notice from the Administrative Agent or the Super-Majority Lenders demanding the deposit of cash collateral pursuant to this Section 2.08(j), or (ii) the Borrower is required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then the Borrower shall deposit, in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to, in the case of an Event of Default, the LC Exposure, and in the case of a payment required by Section 3.04(c), the amount of such excess as provided in Section 3.04(c), as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower or any of its Subsidiaries described in Section 10.01(h) or Section 10.01(i). The Borrower hereby grants to the Administrative Agent, for the benefit of each Issuing Bank and the Lenders, an exclusive first priority and continuing perfected security interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all deposits or wire transfers made thereto, any and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise payable in respect of, or in exchange for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. The Borrower’s obligation to deposit amounts pursuant to this Section 2.08(j) shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower

Credit Agreement

US 793906v.7

or any of its Subsidiaries may now or hereafter have against any such beneficiary, any Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such deposit shall be held as collateral securing the payment and performance of the Borrower’s and any Guarantor’s obligations under this Agreement and the other Loan Documents. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account; provided that investments of funds in such account in investments permitted by Section 9.05(c) or (e) may be made at the option of the Borrower at its direction, risk and expense. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse, on a pro rata basis, each Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated, be applied to satisfy other obligations of the Borrower and the Guarantors, if any, under this Agreement or the other Loan Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, and the Borrower is not otherwise required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived.

ARTICLE III

Payments of Principal and Interest; Prepayments; Fees

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

Section 3.02 Interest.

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

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

(c) Post-Default and Borrowing Base Deficiency Rate. Notwithstanding the foregoing, (i) if an Event of Default has occurred and is continuing as a result of a failure to pay any principal of or interest on any Loan or any fee or other amount payable by the Borrower or any Guarantor hereunder or under any other Loan Document when due, whether at stated maturity, upon acceleration or otherwise, and including any payments in respect of a Borrowing Base Deficiency under Section 3.04(c), then all Loans outstanding in the case of an Event of Default as a result of a failure to pay any principal of or interest on any Loan and such overdue amount in the case of a failure to pay other amounts when due, shall bear interest, after as well as before judgment, at a rate per annum equal to two percent (2%) plus the rate applicable to ABR

Credit Agreement

US 793906v.7

Loans as provided in Section 3.02(a), but in no event to exceed the Highest Lawful Rate, (ii) during any other Event of Default and at the request of the Super-Majority Lenders, then all Loans outstanding shall bear interest, after as well as before judgment, at a rate per annum equal to two percent (2%) plus the rate applicable to ABR Loans as provided in Section 3.02(a), but in no event to exceed the Highest Lawful Rate and (iii) during any Borrowing Base Deficiency, the amount of such Borrowing Base Deficiency shall bear interest, after as well as before judgment, at a rate per annum equal to two percent (2%) plus the rate applicable to ABR Loans as provided in Section 3.02(a), but in no event to exceed the Highest Lawful Rate.

(d) Interest Payment Dates. Accrued interest on each Loan shall be payable in arrears on: (i) with respect to any ABR Loan, the last day of each March, June, September and December; (ii) with respect to any Eurodollar Loan, the last day of the Interest Period applicable to the Borrowing of which such Loan is a part but in all cases to be paid at least every three months and (iii) in any case, on the Termination Date; provided that (A) interest accrued pursuant to Section 3.02(c)(i) shall be payable on demand, (B) in the event of any repayment or prepayment of any Loan (other than an optional prepayment of an ABR Loan prior to the Termination Date), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment, and (C) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

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

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

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

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

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or

Credit Agreement

US 793906v.7

continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing.

Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 3.02.

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

(ii) Upon any redetermination of or adjustment to the amount of the Borrowing Base in accordance with Section 2.07(a) through (d) or Section 8.12(c), if the total Revolving Credit Exposures exceeds the redetermined or adjusted Borrowing Base, then the Borrower shall exercise any one or combination of the following: (A) deliver to the Administrative Agent reserve engineering and mortgages covering such Oil and Gas Properties not previously covered by the Security Instruments with a value and quality satisfactory to the Tier I Lenders in their sole discretion sufficient to eliminate such Borrowing Base Deficiency or (B) prepay the Borrowings in an aggregate principal amount equal to such excess after giving effect to any action taken under (A) hereof, and if any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section

(iii) Upon any adjustments to the Borrowing Base pursuant to Section 2.07(e), Section 2.07(f) or Section 9.11(d), if the total Revolving Credit Exposures exceed the Borrowing Base as adjusted, then the Borrower shall (A) prepay the Borrowings in an aggregate principal amount equal to such excess, and (B) if any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.08(j). The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral on the Business Day immediately following the date it or any Subsidiary receives cash proceeds as a result of such termination, creation of offsetting positions or disposition, as applicable; provided that all payments required to be made pursuant to this Section 3.04(c)(iii) must be made on or prior to the Termination Date.

(iv) If, at any time after the Effective Date, the Borrower issues additional Funded Debt and any Borrowing Base Deficiency exists, then the Borrower shall (a) use 100% of the Net Cash Proceeds from the issuance of such Funded Debt to prepay the Borrowings in an aggregate principal amount equal to such excess, and (b) if, as a result of an LC Exposure, any Borrowing Base Deficiency remains after prepaying all of the Borrowings, deposit with the Administrative Agent on behalf of the Lenders an amount equal to the lesser of such LC Exposure and any remaining Net Cash Proceeds to be held as cash collateral as provided in Section 2.08(j). The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral as soon as practical, and in any event no later than the Business Day after it or any Subsidiary receives such Net Cash Proceeds as a result of such issuance of Funded Debt.

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

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

Accrued commitment fees shall be payable in arrears on the last day of March, June, September and December of each year and on the Termination Date, commencing on the first such date to occur after the date hereof. All commitment fees shall be computed on the basis of a year of 360 days, unless such computation would cause interest on the Notes or on other Indebtedness hereunder to exceed the Highest Lawful Rate, in which case such commitment fees shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(b) Letter of Credit Fees. The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender (subject to Section 4.04(c)(iii)) a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Margin used to determine the interest rate applicable to Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, (ii) to each Issuing Bank a fronting fee equal to 0.50% per annum on the face amount of each Letter of Credit issued by such Issuing Bank hereunder, provided that in no event shall such fee be less than $500 and (iii) to each Issuing Bank, for its own account, its standard fees with respect to the amendment, renewal or extension of any Letter of Credit issued by such Issuing Bank or processing of drawings thereunder. Participation fees accrued through and including the last day of March, June, September and December of each year shall be payable on the third Business Day following such last day, commencing on the first such date to occur after the date of this Agreement and fronting fees with respect to any Letter of Credit shall be payable at the time of issuance of such Letter of Credit; provided that all such fees shall be payable on the Termination Date and any such fees accruing after the Termination Date shall be payable on demand. Any other fees payable to an Issuing Bank pursuant to this Section 3.05(b) shall be payable within 10 days after demand.

ARTICLE IV

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

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

(a) Payments by the Borrower. The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 1:00 p.m., Houston time, on the date when due, in immediately available funds, without defense, deduction, recoupment, set-off or counterclaim (except for Taxes, if any, pursuant to Section 5.03(a), provided that the Borrower has complied with all of the requirements of such Section to the extent applicable). Fees, once paid, shall be fully earned and shall not be refundable under any circumstances, absent manifest error. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices specified in Section 12.01, except payments to be made directly to an Issuing Bank as expressly provided herein and except that payments pursuant to Section 5.01, Section 5.02, Section 5.03 and Section 12.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars.

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

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

Credit Agreement

US 793906v.7

without interest, and (ii) the provisions of this Section 4.01(c) shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or Participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this Section 4.01(c) shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

Section 4.02 Presumption of Payment by the Borrower. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or any Issuing Bank that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or such Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or such Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or such Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

Section 4.03 Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.05(b), Section 2.08(d), Section 2.08(e), Section 4.01(c) or Section 4.02 then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

Section 4.04 Payments and Deductions to a Defaulting Lender.

(a) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.05(b), Section 2.08(d), Section 2.08(e) or Section 4.02 then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid in cash.

(b) If a Defaulting Lender (or a Lender who would be a Defaulting Lender but for the expiration of the relevant grace period) as a result of the exercise of a set-off shall have received a payment in respect of its Revolving Credit Exposure which results in its Revolving Credit Exposure being less than its Applicable Percentage of the aggregate Revolving Credit Exposures, then no payments will be made to such Defaulting Lender until such time as all

Credit Agreement

US 793906v.7

amounts due and owing to the Lenders have been equalized in accordance with each Lender’s respective pro rata share of the Indebtedness. Further, 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, subject to the first sentence of this Section 4.04(b), all principal will be paid ratably as provided in Section 10.02(c).

(c) Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(i) Fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Lender pursuant to Section 3.05.

(ii) The Commitment, the Maximum Credit Amount, the outstanding principal balance of the Loans and participation interests in Letters of Credit of such Defaulting Lender shall not be included in determining whether all Lenders, the Majority Lenders, the Majority Tier I Lenders, the Super-Majority Lenders or the Super-Majority Tier I Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 12.02), provided that any waiver, amendment or modification requiring the consent of each affected Lender and which affects such Defaulting Lender, shall require the consent of such Defaulting Lender; and provided further that no Defaulting Lender shall participate in any redetermination or affirmation of the Borrowing Base, but the Commitments (i.e., the Applicable Percentage of the Borrowing Base of a Defaulting Lender) may not be increased without the consent of such Defaulting Lender.

(iii) If any LC Exposure exists at the time a Lender becomes a Defaulting Lender then:

(A) all or any part of such LC Exposure shall automatically be reallocated (effective as of the date such Lender becomes a Defaulting Lender) among the Non-Defaulting Lenders in accordance with their respective Applicable Percentages but only to the extent (1) the sum of all Non-Defaulting Lenders’ Revolving Credit Exposures plus such Defaulting Lender’s LC Exposure does not exceed the total of all Non-Defaulting Lenders’ Commitments and (2) the conditions set forth in Section 6.02 are satisfied at such time;

(B) if the reallocation described in clause (A) above cannot, or can only partially, be effected, then the Borrower shall within three Business Days following notice by the Administrative Agent cash collateralize such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (A) above) in accordance with the procedures set forth in Section 2.08(e) for so long as such LC Exposure is outstanding;

Credit Agreement

US 793906v.7

(C) if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to this Section 4.04 then the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 3.05(b) with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized;

(D) if the LC Exposure of the Non-Defaulting Lenders is reallocated pursuant to Section 4.04(c), then the fees payable to the Lenders pursuant to Section 3.05(a) and Section 3.05(b) shall be adjusted in accordance with such Non-Defaulting Lenders’ Applicable Percentages after giving effect to such reallocation; or

(E) if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to Section 4.04(c)(iii), then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, all letter of credit fees payable under Section 3.05(b) with respect to such Defaulting Lender’s LC Exposure shall be payable to the Issuing Bank until such LC Exposure is cash collateralized and/or reallocated.

(d) So long as any Lender is a Defaulting Lender, the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure will be 100% covered by the Commitments of the Non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance with Section 4.04(c), and participating interests in any such newly issued or increased Letter of Credit shall be allocated among Non-Defaulting Lenders in a manner consistent with Section 4.04(c)(iii)(A) (and Defaulting Lenders shall not participate therein).

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

ARTICLE V

Increased Costs; Break Funding Payments; Taxes; Illegality

Section 5.01 Increased Costs.

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

(i) impose, modify or deem applicable any reserve (including marginal, special, emergency or supplemental reserves), special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender for Eurocurrency liabilities under Regulation D of the Board (as the same may be amended, supplemented or replaced from time to time) or otherwise; or

Credit Agreement

US 793906v.7

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

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

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

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

(d) Effect of Failure or Delay in Requesting Compensation. Failure or delay on the part of any Lender or any Issuing Bank to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or any Issuing Bank pursuant to this Section 5.01 for any increased costs or reductions incurred more than 180 days prior to the date that such Lender or such Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or such Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof. No Lender or Issuing Bank may make any demand pursuant to this Section 5.01 more than 180 days after the Termination Date.

Section 5.02 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan into an

Credit Agreement

US 793906v.7

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, 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 LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market.

A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section 5.02 and reasonably detailed calculations therefor, upon request of the Borrower, shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

Section 5.03 Taxes.

(a) 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 Taxes; provided that if the Borrower or any Guarantor shall be required by applicable law to deduct any Taxes from such payments, then (i) in the case of Indemnified Taxes or Other Taxes, the sum payable shall be increased as necessary so that after making all required deductions of Indemnified Taxes or Other Taxes (including deductions applicable to additional sums payable under this Section 5.03(a)), the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower or such Guarantor shall make all deductions required by applicable law and (iii) the Borrower or such Guarantor shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Lender and each Issuing Bank, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or such Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 5.03) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate of the Administrative Agent, a

Credit Agreement

US 793906v.7

Lender or an Issuing Bank as to the basis of such Indemnified Taxes or Other Taxes and the amount of such payment or liability under this Section 5.03 shall be delivered to the Borrower and shall be conclusive absent manifest error.

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

(e) Foreign Lenders.

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

(ii) 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 and information reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 5.03(e)(ii), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(f) If the Administrative Agent or any Lender determines in its sole discretion that it has received a refund of any Indemnified Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 5.03, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 5.03 with respect to the Indemnified Taxes or Other Taxes giving rise to such refund), net of all

Credit Agreement

US 793906v.7

reasonable out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund) within ten (10) Business Days of such determination; provided, that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to such Administrative Agent or such Lender in the event such Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (f), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (f) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This paragraph shall not be construed to require any Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

Section 5.04 Designation of Different Lending Office; Replacement of Lenders.

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

(b) Replacement of Lenders. If (i) any Lender requests compensation under Section 5.01, (ii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, (iii) any Lender asserts an illegality under Section 5.05, (iv) any Lender becomes a Defaulting Lender, (v) any Lender does not consent to any proposed increase in or reaffirmation of the Borrowing Base, (vi) in connection with any consent to or approval of any proposed amendment, waiver, consent or release with respect to any Loan Document that requires the consent of each Lender or the consent of each Lender affected thereby, the consent of the Super-Majority Lenders shall have been obtained but any Lender has not so consented to or approved such proposed amendment, waiver, consent or release, or (vii) in connection with any consent to or approval of any proposed amendment, waiver, consent or release with respect to any Loan Document that requires the consent of the Super-Majority Lenders, the consent of the Majority Lenders shall have been obtained but any Lender has not so consented to or approved such proposed amendment, waiver, consent or release, then in any such case, the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 12.04), all its interests, rights and obligations under this Agreement to an assignee or assignees that shall

Credit Agreement

assume such obligations (which assignee may be another Lender, if such Lender accepts such assignment); provided that (A) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (B) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, 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 (C) in the case of any such assignment resulting from a claim for compensation under Section 5.01, for payments required to be made pursuant to Section 5.03 or an illegality under Section 5.05, such assignment will result in a reduction in such compensation or payments or avoid the illegality. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply. Each Lender hereby agrees to make such assignment and delegations required under this Section 5.04(b).

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

(b) All material leases and agreements necessary for the conduct of the business of the Borrower and its Subsidiaries are valid and subsisting, in full force and effect, except to the extent any failure to be valid and subsisting and in full force and effect could not reasonably be expected to have a Material Adverse Effect, and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such lease or agreement, which could reasonably be expected to have a Material Adverse Effect.

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

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

Section 7.18 Gas Imbalances, Prepayments. As of the date hereof, except as set forth on Schedule 7.18 or on the most recent Reserve Report Certificate, on a net basis there are no gas imbalances, take or pay or other prepayments which would require the Borrower or any of its Subsidiaries to deliver, in the aggregate, two percent (2%) or more of the monthly production from Hydrocarbons produced from the Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor.

Section 7.19 Marketing of Production.

Immediately after giving effect to the Transactions, (a) the aggregate assets (after giving effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any similar arrangement), at a fair valuation, of the Borrower and the Guarantors, taken as a whole, will exceed the aggregate Debt of the Borrower and the Guarantors on a consolidated basis, as such Debt becomes absolute and matures, (b) neither the Borrower nor any Guarantor will have incurred, intended to incur, or believes that it will incur, Debt beyond its ability to pay such Debt (after taking into account the timing and amounts of cash to be received by it and the amounts to be payable on or in respect of its liabilities, and giving effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any similar arrangement) as such Debt becomes absolute and matures and (c) neither the Borrower nor any Guarantor will have (and will have no reason to believe that it will have thereafter) unreasonably small capital for the conduct of its business.

Credit Agreement

US 793906v.7

(b) If the Borrower has provided title information for additional Properties under Section 8.12(a), the Borrower shall, within 60 days of notice from the Administrative Agent that title defects or exceptions exist with respect to such additional Properties, either (i) cure any such title defects or exceptions (including defects or exceptions as to priority) which are not permitted by Section 9.03, (ii) substitute acceptable Mortgaged Properties with no title defects or exceptions (other than Liens which are permitted by Section 9.03) having an equivalent value or (iii) deliver title information in form and substance reasonably acceptable to the Administrative Agent so that the Administrative Agent shall have received, together with title information previously delivered to the Administrative Agent, reasonably satisfactory title information on such portion of Oil and Gas Properties evaluated by such Reserve Report, not to exceed 80% of the total value thereof, as may be reasonably requested by the Administrative Agent.

(c) If the Borrower is unable to cure any title defect requested by the Administrative Agent or the Lenders to be cured within the 60-day period or the Borrower does not comply with the requirements to provide acceptable title information as required by Section 8.12(a) and Section 8.12(b), such default shall not be a Default, but instead the Administrative Agent and/or the Majority Lenders shall have the right to exercise the following remedy in their sole discretion from time to time, and any failure to so exercise this remedy at any time shall not be a waiver as to future exercise of the remedy by the Administrative Agent or the Lenders. To the extent that the Administrative Agent or the Majority Lenders are not reasonably satisfied with title to any Mortgaged Property after the 60-day period has elapsed, such unacceptable Mortgaged Property shall not count towards the requirements of Section 8.12(a) and Section 8.12(b), and the Administrative Agent may send a notice to the Borrower and the Lenders that the then outstanding Borrowing Base shall be reduced by an amount as determined by the Majority Lenders to cause the Borrower to be in compliance with the requirement to provide acceptable title information pursuant to Section 8.12(a) and Section 8.12(b).

In the event that the Mortgaged Properties do not represent at least 80% of such total value, then the Borrower shall, and shall cause its Subsidiaries to, grant, within ninety (90) days of the delivery of the certificate contemplated by Section 8.11(c), to the Administrative Agent or its designee as security for the Indebtedness a first-priority Lien interest (subject to Liens permitted by Section 9.03 which may attach to Mortgaged Property) on additional Oil and Gas Properties not already subject to a Lien of the Security Instruments such that after giving effect thereto, the Mortgaged Properties will represent at least 80% of such total value. All such Liens will be created and perfected by and in accordance with the provisions of deeds of trust, security agreements and financing statements or other Security Instruments, all in form and substance reasonably satisfactory to the Administrative Agent or its designee and in

US 793906v.7

sufficient executed (and acknowledged where necessary or appropriate) counterparts for recording purposes.

(i) Swap Agreements in respect of commodities (x) with an Approved Counterparty and (y) the notional volumes for which (when aggregated with the notional volumes under all other commodity Swap Agreements then in effect other than swaps covering (A) basis differential or (B) oil spread timing risks, in each case on volumes already hedged pursuant to other Swap Agreements) do not exceed, as of the date such Swap Agreement is executed, (I) 80% of the reasonably anticipated projected production (based upon the Borrower’s internal projections) for each month during the period during which such Swap Agreement is in effect for each of crude oil and natural gas, calculated separately, for each calendar month during the period through the remainder of the then current calendar year and for the period of four calendar years thereafter and (II) 70% of the reasonably anticipated projected production (based upon the Borrower’s internal projections) for each month during the period during which such Swap Agreement is in effect for each of crude oil and natural gas, calculated separately, for each calendar month during the period starting with the 5th calendar year thereafter.

Notwithstanding the foregoing, but subject to the cure provisions of Section 9.16(i), the notional volumes in respect of all commodity Swap Agreements (when aggregated with the notional volumes under all other commodity Swap Agreements then in effect other than swaps covering (1) basis differential or (2) oil spread timing risks, in each case on volumes already hedged pursuant to other Swap Agreements and Acquisition Swap Agreements) will not, as of the first day of the next calendar month following each Date of Determination (the “Applicable Date”), for each month during the period of six calendar months commencing on the Applicable Date, exceed the actual net monthly physical production from proved, developed producing reserves (regardless of projected production levels) for the calendar month most recently ended prior to such Date of Determination, calculated separately for each of crude oil and natural gas.

(b) Notwithstanding anything in Section 9.16(a)(i) to the contrary, the Borrower may enter into commodity Swap Agreements with any Lender or Affiliate of a Lender having notional volumes in excess of the amounts set forth in Section 9.16(a)(i) (such Swap Agreements being “Acquisition Swap Agreements”) in anticipation of the acquisition of Oil and Gas Properties or Equity Interests of Persons owning Oil and Gas Properties in a transaction not prohibited by this Agreement (any such Oil and Gas Properties being referred to herein as the “Target Oil and Gas Properties”) if (x) the Borrower or a Subsidiary has entered into a definitive purchase and sale agreement for such Target Oil and Gas Properties, (y) the tenor of any such Acquisition Swap Agreement does not exceed 60 months from the expected date of closing of such acquisition and (z) the notional volumes hedged pursuant to any such Acquisition Swap Agreement (when aggregated with the notional volumes hedged pursuant to all other Acquisition Swap Agreements then in effect other than swaps covering (i) basis differential or (ii) oil spread timing risks, in each case on volumes already hedged pursuant to other Acquisition Swap Agreements) do not exceed, as of the date such Acquisition Swap Agreement is executed, 100% of the reasonably anticipated projected production from all Oil and Gas Properties constituting Target Oil and Gas Properties as of such date that are identified by the Borrower’s internal engineers as proved reserves for each month during the period during which such Acquisition Swap Agreement is in effect for each of crude oil and natural gas, calculated separately.

(c) If, as of any Test Date that occurs while one or more Acquisition Swap Agreements are in effect, the Borrower determines that all Acquisition Swap Agreements then in effect (when aggregated with other commodity Swap Agreements then in effect other than swaps covering basis differential or oil spread timing risks, in each case on volumes already hedged pursuant to other Swap Agreements) have notional volumes in excess of the amounts set forth in Section 9.16(a)(i), then the Borrower shall (i) maintain unused availability under this Agreement in an amount at least equal to the Minimum Availability Amount until such time as the Borrower is in compliance with Section 9.16(a)(i) and (ii) furnish to the Administrative Agent, no later than the close of business on such Test Date, a statement of the Aggregate Exposure as of the last preceding Business Day as of which such amount could be calculated (and in any event, not prior to the Business Day on which written confirmations in respect of any applicable Swap Agreements used in any such calculation are available).

(d) The Borrower shall terminate, create off-setting positions, otherwise unwind existing Swap Agreements or take other actions permitted by this Agreement within three (3) Business Days after a Termination Event Date occurs with respect to any Acquisition Swap Agreement to the extent necessary to be in compliance with Section 9.16(a)(i).

(e) If the acquisition of any Target Oil and Gas Properties has not been consummated within 120 days of the execution of the related Acquisition Swap Agreements with the effect that the Borrower is not then compliant with Section 9.16(a), then until the earlier of (1) the date such acquisition is consummated or (2) a Termination Event Date, the Borrower shall secure such Acquisition Swap Agreements in an amount not less than the amount of Exposure with respect to such Acquisition Swap Agreements (to the extent such Exposure is a positive number) by pledging to the Administrative Agent for the benefit of the relevant counterparties cash or securities as may be mutually agreed by the Borrower and such swap counterparty(ies).

Credit Agreement

US 793906v.7

(f) If, at any time (other than during an Exemption Period), the Borrower determines that the notional amounts of Swap Agreements in respect of interest rates exceed 100% of the then outstanding principal amount of the Borrower’s Debt for borrowed money which bears interest at a floating rate, then the Borrower shall, within thirty (30) days of such determination, terminate, create off-setting positions or otherwise unwind existing Swap Agreements in order to comply with this Section 9.16.

(g) If, at any time during an Exemption Period, the Borrower determines that the notional amounts of Swap Agreements in respect of interest rates exceed 100% of the outstanding principal amount of the Borrower’s Debt for borrowed money which bears interest at a floating rate calculated on a pro forma basis assuming any relevant acquisition subject of such Exemption Period were funded completely with borrowed money which bears interest at a floating rate, then the Borrower shall, within thirty (30) days of such determination, terminate, create off-setting positions or otherwise unwind existing Swap Agreements such that the notional volumes do not exceed 100% of such pro forma principal amount.

(h) Notwithstanding anything to the contrary in this Section 9.16, (1) there shall be no prohibition against the Borrower entering into any “put” or “call spread option” contracts or commodity price floors so long as such agreements are entered into for non-speculative purposes and in the ordinary course of business for the purpose of hedging against fluctuations of commodity prices and (2) any “swaption” entered into by the Borrower shall be counted against the sublimits contained in this Section 9.16 for the purpose of hedging against fluctuations of commodity prices.

(i) If, as of any Applicable Date, the Borrower determines that the aggregate notional volumes of all commodity Swap Agreements (other than Acquisition Swap Agreements or swaps covering (A) basis differential and (B) oil spread timing risks excluded for purposes of clause (i) of Section 9.16(a)) for each month in the six (6) calendar month period commencing on the Applicable Date (in each case calculated for each commodity separately) would exceed the actual net monthly production from proved, developed producing reserves for the calendar month immediately preceding the Date of Determination occurring immediately prior to such Applicable Date, then the Borrower shall, prior to the last day of the calendar month during which such Applicable Date occurred, terminate, create off-setting positions, otherwise unwind existing Swap Agreements or take other actions permitted by this Agreement (including delivering revised forecasts of anticipated projected production reasonably acceptable to the Administrative Agent; provided that the delivery of revised forecasts cannot cure the requirements set forth in the second paragraph of clause (i) of Section 9.16(a)) such that, by the end of such calendar month, the Borrower will be in compliance with the limitations set forth in Section 9.16(a) (calculated for each commodity separately).

Section 9.17 Tax Status as Partnership. The Borrower shall not alter its status as a partnership for purposes of United States Federal Income taxes.

ARTICLE XI

The Administrative Agent

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

Section 11.02 Duties and Obligations of Administrative Agent. The Administrative Agent shall have no duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing (the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law; rather, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties), (b) the Administrative Agent shall have no duty to take any discretionary action or exercise any discretionary powers, except as provided in Section 11.03, and (c) except as expressly set forth herein, the Administrative Agent shall have no duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document

Credit Agreement

US 793906v.7

delivered hereunder or under any other Loan Document or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or in any other Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, (v) the satisfaction of any condition set forth in Article VI or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent, (vi) the existence, value, perfection or priority of any collateral security or the financial or other condition of the Borrower and its Subsidiaries or any other obligor or guarantor, or (vii) any failure by the Borrower or any other Person (other than itself) to perform any of its obligations hereunder or under any other Loan Document or the performance or observance of any covenants, agreements or other terms or conditions set forth herein or therein. For purposes of determining compliance with the conditions specified in Article VI, each Lender shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received written notice from such Lender prior to the proposed closing date specifying its objection thereto.

Section 11.03 Action by Agent. The Administrative Agent shall have no duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise in writing as directed by the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) and in all cases the Administrative Agent shall be fully justified in failing or refusing to act hereunder or under any other Loan Documents unless it shall (a) receive written instructions from the Majority Lenders or the Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) specifying the action to be taken and (b) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of taking or continuing to take any such action. The instructions as aforesaid and any action taken or failure to act pursuant thereto by the Administrative Agent shall be binding on all of the Lenders. If a Default has occurred and is continuing, then the Administrative Agent shall take such action with respect to such Default as shall be directed by the requisite Lenders in the written instructions (with indemnities) described in this Section 11.03, provided that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interests of the Lenders. In no event, however, shall the Administrative Agent be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, the Loan Documents or applicable law. If a Default has occurred and is continuing, the Syndication Agents and the Co-Documentation Agents shall have no obligation to perform any act in respect thereof. No Agent shall be liable for any action taken or not taken by it with the consent or at the request of the Majority Lenders or the Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02), and otherwise the Administrative Agent shall not be liable for any action taken or not taken by it hereunder or under any other Loan Document or under any other document or instrument referred to or

Credit Agreement

US 793906v.7

provided for herein or therein or in connection herewith or therewith INCLUDING ITS OWN ORDINARY NEGLIGENCE, except for its own gross negligence or willful misconduct.

Section 11.04 Reliance by Agent. Each Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. Each Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon and each of the Borrower, the Lenders and each Issuing Bank hereby waives the right to dispute such Agent’s record of such statement, except in the case of gross negligence or willful misconduct by such Agent. Each Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. The Agents may deem and treat the payee of any Note as the holder thereof for all purposes hereof unless and until a written notice of the assignment or transfer thereof permitted hereunder shall have been filed with the Administrative Agent.

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

Section 11.06 Resignation of Agents. Subject to the appointment and acceptance of a successor Agent as provided in this Section 11.06, any Agent may resign at any time by notifying the Lenders, each Issuing Bank and the Borrower and any Agent may be removed at any time with or without cause by the Majority Lenders. Upon any such resignation or removal, the Majority Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring Agent may, on behalf of the Lenders and each Issuing Bank, appoint a successor Agent. Upon the acceptance of its appointment as Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Agent’s resignation hereunder, the provisions of this Article XI and Section 12.03 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Agent.

Section 11.07 Agents and Lenders. Each bank serving as an Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the

Credit Agreement

US 793906v.7

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

Section 11.08 No Reliance.

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

(b) The Lenders acknowledge that the Administrative Agent and the Arrangers are acting solely in administrative capacities with respect to the structuring and syndication of this facility and have no duties, responsibilities or liabilities under this Agreement and the other Loan Documents other than their administrative duties, responsibilities and liabilities specifically as set forth in the Loan Documents and in their capacity as Lenders hereunder. In structuring, arranging or syndicating this facility, each Lender acknowledges that the Administrative Agent and/or Arrangers may be agents or lenders under these Notes, other loans or other securities and waives any existing or future conflicts of interest associated with their role in such other debt instruments. If in its administration of this facility or any other debt instrument, the Administrative Agent determines (or is given written notice by any Lender) that a conflict exists, then it shall eliminate such conflict within 90 days or resign pursuant to Section 11.06 and shall have no liability for action taken or not taken, other than actions taken or not taken which represent Administrative Agent’s gross negligence or willful misconduct, while such conflict existed.

Section 11.09 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement,

Credit Agreement

US 793906v.7

adjustment, composition or other judicial proceeding relative to the Borrower or any of its Subsidiaries, the Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise:

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

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

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

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

Section 11.10 Authority of Administrative Agent to Release Collateral and Liens. Each Lender, each Issuing Bank and each Secured Hedge Provider hereby authorizes the Administrative Agent to release any collateral that is permitted to be sold or released pursuant to the terms of the Loan Documents.

Section 12.02 Waivers; Amendments.

(a) No failure on the part of the Administrative Agent, any other 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, any other Agent, each Issuing Bank and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by Section 12.02(b), and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.

(b) In each instance subject to Section 4.04(c)(ii), neither this Agreement nor any provision hereof nor any Security Instrument nor any other Loan Document nor any provision thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Majority Lenders or by the Borrower and the Administrative Agent with the written 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 consent or deemed consent of each Tier I Lender, decrease or maintain the Borrowing Base without the consent of the Super-Majority Tier I Lenders, or modify in any manner Section 2.07 without the consent of

each Tier I Lender, (iii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, or reduce any other Indebtedness hereunder or under any other Loan Document, without the written consent of each Lender affected thereby, (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 any other Indebtedness hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Termination Date or the Maturity Date without the written consent of each Lender affected thereby, (v) change Section 4.01(b), Section 4.01(c) or Section 10.02(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender adversely affected thereby, (vi) waive or amend Section 6.01, or Section 8.13 or change the definition of the terms “Domestic Subsidiary”, “Foreign Subsidiary”, “Material Domestic Subsidiary” or “Subsidiary”, without the written consent of each Lender, (vii) release any Guarantor (except as set forth in the Guaranty Agreement), release all or a substantial portion of the collateral (other than as provided in Section 11.10), or reduce the percentage set forth in Section 8.13(a) to less than 80%, without the written consent of each Lender, (viii) modify the terms of clause (b) of the definition of “Indebtedness”, the definition of “Secured Hedge Provider”, the definition of “Secured Swap Agreement”, Section 12.14, or any of the provisions of this Section 12.02(b) without the consent of each Secured Hedge Provider adversely affected thereby, (ix) change any of the provisions of this Section 12.02(b) or the definition of “Majority Lenders” or “Super-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, (x) change the definition of “Majority Tier I Lenders”, “Super-Majority Tier I Lenders” or “Tier I Lenders” without the written consent of each Tier I Lender or (xi) amend or otherwise modify any Security Instrument in a manner that results in the obligations of the Borrower or any Subsidiary owing to any Secured Hedge Provider under any Secured Swap Agreement no longer being secured pursuant to such Security Instrument, without the written consent of such Secured Hedge Provider; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, any other Agent, or any Issuing Bank hereunder or under any other Loan Document without the prior written consent of the Administrative Agent, such other Agent or such Issuing Bank, as the case may be. Notwithstanding the foregoing, any supplement to Schedule 7.14 (Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental schedule clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders.

Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of any Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in Section 12.04(c)) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, each Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

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

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

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

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

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

Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 12.04(c).

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

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

In addition such agreement must provide that the Participant be bound by the provisions of Section 12.11. Subject to Section 12.04(c)(ii), the Borrower agrees that each Participant shall be entitled to the benefits of Section 5.01, Section 5.02 and Section 5.03 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.04(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.08 as though it were a Lender, provided such Participant agrees to be subject to Section 4.01(c) as though it were a Lender.

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

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

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

The provisions of Section 5.01, Section 5.02, Section 5.03, Section 12.03, Section 12.11 and Article XI shall survive and remain in full force and effect regardless of the consummation of the Transactions, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement, any other Loan Document or any provision hereof or thereof.

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

Section 12.06 Counterparts; Integration; Effectiveness.

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

(b) This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the 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.

Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

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

Section 12.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations (of whatsoever kind, including, without limitation, 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 of its Subsidiaries against any of and all the obligations of the Borrower or any of its Subsidiaries 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. Each Lender or its Affiliate agrees to promptly notify the Borrower and the Administrative Agent after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application. The rights of each Lender under this Section 12.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender or its Affiliates may have.

Each of the Agents, each Issuing Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority or self-regulatory body, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement or any other Loan Document, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section 12.11, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any Swap Agreement relating to the Borrower and their obligations, (g) with the consent of the Borrower, (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section 12.11 or (ii) becomes available to the Administrative Agent, any Issuing Bank or any Lender on a nonconfidential basis from a source other than the Borrower, or (i) to the National Association of Insurance Commissioners or any similar organization or any nationally recognized rating agency that requires access to information about a Lender’s investment portfolio in connection with ratings issued with respect to such Lender. For the purposes of this Section 12.11, “Information” means all information received from the Borrower or any of its Subsidiaries relating to the Borrower or any of its Subsidiaries and their businesses, other than any such information that is available to the Administrative Agent, any Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Borrower or any of its Subsidiaries; provided that, in the case of information received from the Borrower, or any of its Subsidiaries after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section 12.11 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

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 agrees 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. Accordingly, each Lender represents to the Borrower and the Administrative Agent that it has identified in its Administrative Questionnaire a credit contact

who may receive information that may contain material non-public information in accordance with its compliance procedures and applicable law, including federal and state securities laws.

Section 12.12 Interest Rate Limitation. It is the intention of the parties hereto that each Lender shall conform strictly to usury laws applicable to it. Accordingly, if the Transactions would be usurious as to any Lender under laws applicable to it (including the laws of the United States of America and the State of Texas or any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any of the Loan Documents or any agreement entered into in connection with or as security for the Loans, it is agreed as follows: (a) the aggregate of all consideration which constitutes interest under law applicable to any Lender that is contracted for, taken, reserved, charged or received by such Lender under any of the Loan Documents or agreements or otherwise in connection with the Loans shall under no circumstances exceed the maximum amount allowed by such applicable law, and any excess shall be canceled automatically and if theretofore paid shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Borrower); and (b) in the event that the maturity of the Loans is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Lender may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated and spread throughout the stated term of the Loans until payment in full so that the rate or amount of interest on account of any Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at any time and from time to time (i) the amount of interest payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to such Lender pursuant to this Section 12.12 and (ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to such Lender would be less than the amount of interest payable to such Lender computed at the Highest Lawful Rate applicable to such Lender, then the amount of interest payable to such Lender in respect of such subsequent interest computation period shall continue to be computed at the Highest Lawful Rate applicable to such Lender until the total amount of interest payable to such Lender shall equal the total amount of interest which would have been payable to such Lender if the total amount of interest had been computed without giving effect to this Section 12.12. To the extent that Chapter 303 of the Texas Finance Code is relevant for the purpose of determining the Highest Lawful Rate applicable to a Lender, such Lender elects to determine the applicable rate ceiling under such Chapter by the weekly ceiling from time to time in effect. Chapter 346 of the Texas Finance Code does not apply to the Borrower’s obligations hereunder. The Loans are not primarily for personal, family or household use.

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

Section 12.14 Collateral Matters; Swap Agreements. The benefit of the Security Instruments and of the provisions of this Agreement relating to any collateral securing the Indebtedness shall also extend to and be available to each Secured Hedge Provider on a pro rata basis in respect of any obligations of the Borrower or any of its Subsidiaries owed to such Secured Hedge Provider under any Secured Swap Agreement. Except as set forth in Sections 12.02(b)(viii) and (x), no Secured Hedge Provider shall have any voting rights under any Loan Document as a result of the existence of obligations owed to it under any Secured Swap Agreement.

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

Section 12.16 USA Patriot Act Notice. Each Lender hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act.

Section 12.17 No Fiduciary Duty. Each Agent, each Lender and their Affiliates (collectively, solely for purposes of this paragraph, the “Lenders”), may have economic interests that conflict with those of the Borrower and the Guarantors, their respective stockholders and/or their affiliates. The Borrower agrees that nothing in the Loan Documents and nothing in connection with the transactions related thereto will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or other implied duty between any Lender, on the one hand, and the Borrower and any Guarantor, its stockholders or its affiliates, on the other. The Borrower acknowledges and agrees that (a) the transactions contemplated by the Loan Documents (including the exercise of rights and remedies hereunder and thereunder) are arm’s-length commercial transactions between the Lenders, on the one hand, and the Borrower on the other, and (b) in connection therewith and with the process leading thereto, (i) no Lender has assumed an advisory or fiduciary responsibility in favor of the Borrower or any Guarantor, its stockholders or its Affiliates with respect to the transactions contemplated hereby (or the exercise of rights or remedies with respect thereto) or the process leading thereto (irrespective of whether any Lender has advised, is currently advising or will advise the Borrower or any Guarantor, its stockholders or its Affiliates on other matters) or any other obligation to the Borrower or any Guarantor except the obligations expressly set forth in the Loan Documents and (ii) each Lender is acting solely as principal and not as the agent or fiduciary of the Borrower or any Guarantor, its management, stockholders, creditors or any other Person. The Borrower acknowledges and agrees that it has consulted its own legal and financial advisors to the extent it deemed appropriate and that it is responsible for making its own independent judgment with respect to such transactions and the process leading thereto. The Borrower agrees that it will not claim that any Lender has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Borrower or any Guarantor, in connection with such transaction or the process leading thereto.
