Item 1.01 Entry into a Material Definitive Agreement.

The information discussed in Items 2.01 and 2.03 below is incorporated herein by reference.

Item 2.01 Completion of Acquisition or Disposition of Assets.

Constellation Energy Partners LLC (the “Company”) previously announced in its Form 8-K filed on February 25, 2008, that it had entered into a definitive purchase agreement (the “Purchase Agreement”) with CoLa Resources LLC (“CoLa”) to acquire all of CoLa’s interests in 83 non-operated producing wells located in the Woodford Shale in the Arkoma Basin, Oklahoma with an average net revenue interest per well of 9.2 % for an aggregate purchase price of approximately $53.4 million, subject to purchase price adjustments (the “Acquisition”). CoLa is an affiliate of Constellation Energy Group, Inc., the Company’s sponsor. The transaction was previously approved by the Company’s conflicts committee. In its review, the Company’s conflicts committee considered various economic factors (including historical and estimated future production, estimated proved reserves, future pricing estimates and operating cost estimates) regarding the Acquisition, determined that the Acquisition was fair and in the best interests of the Company and approved the transaction. On March 31, 2008, the Company amended the Purchase Agreement to provide that CoLa would obtain certain consents to assign a related lease and amend an exhibit to the original Purchase Agreement. On March 31, 2008, the Company also closed the Acquisition. The description of the Acquisition and terms of the Purchase Agreement contained in the Company’s 8-K filed on February 25, 2008 are incorporated herein by reference. A copy of the Purchase Agreement and the amendment to the Purchase Agreement are filed as Exhibit 2.1 and Exhibit 2.2, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.

In connection with the closing of the Acquisition, Constellation Energy Commodities Group, Inc. (“CCG”), an affiliate of the Company’s sponsor, entered into a guaranty agreement (the “Guaranty Agreement”) with a wholly owned subsidiary of the Company. Pursuant to the Guaranty Agreement, CCG agreed to guarantee potential payment obligations of CoLa under certain indemnification provisions of the Purchase Agreement. The maximum liability under the Guaranty Agreement for CCG is $10.7 million for certain indemnity related obligations under the Purchase Agreement and $9.2 million for certain title defect obligations under the Purchase Agreement. A copy of the Guaranty Agreement is filed as Exhibit 2.3 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation Under an Off-Balance Sheet Arrangement of a Registrant.

On March 28, 2008, the Company entered into a new credit agreement and an amended and restated credit agreement, each as discussed below. The two agreements contain similar commercial terms with the same lenders participating in the same applicable percentages. A cross-default feature provides that an event of default under one agreement constitutes an event of default under the other. Each credit agreement is secured by distinct mortgages of properties as well as guarantees by certain of the Company’s affiliates.

New Credit Agreement

On March 28, 2008, the Company entered into a new $500.0 million secured credit agreement (the “Credit Facility”) with The Royal Bank of Scotland plc as administrative agent (the “Administrative Agent”). The amount available for borrowing at any one time is limited to the borrowing base for the Company’s properties not in the State of Alabama, which is initially set at $150.0 million. The borrowing base will be re-determined semi-annually by the lenders in their sole discretion based on reserve reports as prepared by reserve engineers, together with, among other things, the natural gas and oil prices at such time. Any increase in each borrowing base must be approved by 100% of the lenders. Under certain conditions, the credit facility may be increased up to an additional $250.0 million. The Credit Facility matures on October 31, 2010.

Borrowings under the Credit Facility are available for acquisition, exploration, operation and maintenance of natural gas and oil properties located in states other than Alabama, payment of expenses incurred in connection with the credit facilities, working capital and general limited liability company purposes. The Credit Facility has a sub-limit of $20.0 million which may be used for the issuance of letters of credit.

At the Company’s election, interest for borrowings under the Credit Facility is determined by reference to (i) the London interbank rate, or LIBOR, plus an applicable margin between 1.25% and 2.00% per annum based on utilization or (ii) a domestic bank rate plus an applicable margin between 0.25% and 1.00% per annum based on utilization. Interest on borrowings under the Credit Facility is generally payable quarterly for domestic bank rate loans and at the applicable maturity date for LIBOR loans.

The Credit Facility contains various covenants that limit, among other things, the Company’s, and certain of the Company’s subsidiaries’, ability to incur certain indebtedness, grant certain liens, merge or consolidate, sell all or substantially all of the Company’s assets, make certain loans, acquisitions, capital expenditures and investments, make distributions other than from available cash.

In addition, the Company, is required to maintain (i) a ratio of debt to Adjusted EBITDA (defined as, for any period, the sum of consolidated net income for such period plus the following expenses or charges to the extent deducted from consolidated net income in such period: interest expense, depreciation, depletion, amortization, write off of deferred financing fees, impairment of long-lived assets, (gain) loss or sale of assets, (gain) loss from equity investment, accretion of asset retirement obligation, unrealized (gain) loss on natural gas derivatives and realized (gain) loss on cancelled natural gas derivatives, and other similar charges) of not more than 3.50 to 1.00; (ii) Adjusted EBITDA to cash interest expense of not less than 2.5 to 1.0; (iii) consolidated current assets, including the unused amount of the total commitments but excluding current non-cash assets, to consolidated current liabilities, excluding non-cash liabilities, of not less than 1.0 to 1.0, all calculated pursuant to the requirements under SFAS No. 133 and 143 (including the current liabilities in respect of the termination of natural gas and interest rate swaps).

The Credit Facility also includes customary events of default, including events of default relating to non-payment of principal, interest or fees, inaccuracy of representations and warranties in any material respect when made or when deemed made, violation of covenants, cross-defaults, bankruptcy and insolvency events, certain unsatisfied judgments, guaranties not being valid under the Credit Facility and a change of control. If an event of default occurs under the credit facility, the lenders will be able to accelerate the maturity of the Credit Facility and exercise other rights and remedies.

Borrowings under the Credit Facility are secured by various mortgages of properties that the Company owns as well as a security and pledge agreement among the Company and certain of its subsidiaries and the Administrative Agent.

On March 28, 2008, the Company borrowed $131.0 million under the term loan portion of the Credit Facility. A portion of the proceeds of the borrowings (less associated transaction costs) were used to finance the aggregate consideration for the Acquisition, and a portion of the proceeds of the borrowings (less associated transaction costs) were used to repay existing indebtedness.

The foregoing description is qualified in its entirety by reference to the full text of the Credit Facility, which is attached as Exhibit 10.1 to this Current Report on Form 8-K and incorporated in this Item 2.03 by reference.

Amended and Restated Credit Agreement

In addition, on March 28, 2008, the Company amended and restated its existing credit facility by entering into an amended and restated credit agreement with the Administrative Agent (the “Amended and Restated Credit Facility”). The amount available for borrowing at any one time is limited to the borrowing base for the Company’s properties in the State of Alabama, which is initially set at $90.0 million. The borrowing base will be re-determined semi-annually by the lenders in their sole discretion based on reserve reports as prepared by reserve engineers, together with, among other things, the natural gas and oil prices at such time. Any increase in each borrowing base must be approved by 100% of the lenders. The Amended and Restated Credit Facility matures on October 31, 2010.

Borrowings under the Amended and Restated Credit Facility are available for acquisition, exploration, operation and maintenance of natural gas and oil properties located in Alabama, payment of expenses incurred in connection with the credit facilities, working capital and general limited liability company purposes. The Amended and Restated Credit Facility has a sub-limit of $20.0 million which may be used for the issuance of letters of credit.

At the Company’s election, interest for borrowings under the Amended and Restated Credit Facility is determined by reference to (i) the London interbank rate, or LIBOR, plus an applicable margin between 1.25% and 2.00% per annum based on utilization or (ii) a domestic bank rate plus an applicable margin between 0.25% and 1.00% per annum based on utilization. Interest on borrowings under the Amended and Restated Credit Facility is generally payable quarterly for domestic bank rate loans and at the applicable maturity date for LIBOR loans.

The Amended and Restated Credit Facility contains various covenants that limit, among other things, the Company’s, and certain of the Company’s subsidiaries’, ability to incur certain indebtedness, grant certain liens, merge or consolidate, sell all or substantially all of the Company’s assets, make certain loans, acquisitions, capital expenditures and investments, make distributions other than from available cash.

In addition, the Company, is required to maintain (i) a ratio of debt to Adjusted EBITDA (defined as, for any period, the sum of consolidated net income for such period plus the following expenses or charges to the extent deducted from consolidated net income in such period: interest expense, depreciation, depletion, amortization, write off of deferred financing fees, impairment of long-lived assets, (gain) loss or sale of assets, (gain) loss from equity investment, accretion of asset retirement obligation, unrealized (gain) loss on natural gas derivatives and realized (gain) loss on cancelled natural gas derivatives, and other similar charges) of not more than 3.50 to 1.00; (ii) Adjusted EBITDA to cash interest expense of not less than 2.5 to 1.0; (iii) consolidated current assets, including the unused amount of the total commitments but excluding current non-cash assets, to consolidated current liabilities, excluding non-cash liabilities, of not less than 1.0 to 1.0, all calculated pursuant to the requirements under SFAS No. 133 and 143 (including the current liabilities in respect of the termination of natural gas and interest rate swaps).

The Amended and Restated Credit Facility also includes customary events of default, including events of default relating to non-payment of principal, interest or fees, inaccuracy of representations and warranties in any material respect when made or when deemed made, violation of covenants, cross-defaults, bankruptcy and insolvency events, certain unsatisfied judgments, guaranties not being valid under the Amended and Restated Credit Facility and a change of control. If an event of default occurs under the credit facility, the lenders will be able to accelerate the maturity of the credit agreement and exercise other rights and remedies.

Borrowings under the Amended and Restated Credit Facility are secured by various mortgages of properties the Company owns in Alabama as well as a security and pledge agreement among the Company and certain of its subsidiaries and the Administrative Agent.

On March 28, 2008, the Company borrowed $81.0 million under the term loan portion of the Amended and Restated Credit Agreement, the proceeds of which (less associated transaction costs) were used to repay existing indebtedness.

A copy of the Amended and Restated Credit Facility is filed as Exhibit 10.2 to this Form 8-K and is incorporated herein by reference.

Notwithstanding the foregoing, in the event of mechanical failure in any Wellbore that permanently disrupts the production of hydrocarbons from the Wellbore, should Buyer elect to attempt to reestablish production from the same or shallower stratigraphic interval that the Wellbore was producing from prior to such mechanical failure through sidetracking from the Wellbore, Buyer shall have the right to do so provided that the bottom hole location of such sidetracking is (a) no deeper than and (b) no more than 100 feet from, the bottom hole location of the Wellbore prior to mechanical failure. Seller retains any and all executive rights related to the Wellbores, including all rights, if any, to negotiate with lessors, to grant leases or to rental or bonus payments (“Executive Rights”) and Buyer hereby waives any and all such rights as well as any right to protest any down-spacing wells, increased density wells, or exception location wells Seller, or its successors and assigns, may choose to drill.

1.2. Equipment. All of Seller’s interest in all casing pipe, downhole equipment and any additional equipment, fixtures or physical facilities attached to or a part of the Wellbores (“Equipment”).

12. Taxes, Prorations and Assumption of Obligations.

12.1. Tax Prorations. Real and personal property taxes for the Properties shall be prorated between Buyer and Seller as of the Effective Time. If the actual taxes are not known on the Closing Date, Seller’s share of such taxes shall be determined by using (a) the rates and millage for the year prior to the year in which the Closing occurs, with appropriate adjustments for any known and verifiable changes thereto, and (b) the assessed values for the year in which Closing occurs. When Buyer receives the actual tax statements for the Properties from the appropriate taxing authorities, Buyer shall deliver to Seller a copy of such statements, together with the amount, if any, by which Seller’s proration exceeds or is less than the proration that would have been made had actual tax statements been used to calculate Seller’s proration. If the proration for Seller that would have been made using actual tax statements exceeds that made at Closing, Seller shall pay to Buyer such difference within three (3) Business Days of receipt of such statement. If the proration for Seller that would have been made using actual tax statements is less than that made at Closing, Buyer shall pay to Seller such difference within three (3) Business Days of receipt of such statement.

12.2. Tax Returns. Seller shall cause to be included in its income tax return for all periods ending at the Effective Time, all of the items of income, gain, loss, deduction and credit with respect to the Properties which are required to be included therein, shall cause such tax returns to be filed with the appropriate taxing authorities, and shall be responsible for the timely payment (and entitled to any refund) of all taxes due with respect to the periods covered by such tax returns.

12.3. Assumption of Obligations. At Closing, Buyer shall assume the following (“Assumed Obligations”): (1) the obligation to (i) plug and abandon the Wellbores, (ii) remove and dispose of all structures and equipment constituting a part of the Wellbores, and (iii) dispose of all NORM and all other pollutants, wastes, contaminants, or hazardous, extremely hazardous, or toxic materials, substances, chemicals or wastes generated by the production of Substances or used in connection therewith, whether before or after the Effective Time; (2) all obligations and liabilities arising from or in connection with any gas production, pipeline, storage, processing or other imbalance attributable to Substances, whether before or after the Effective Time; and (3) all other costs, obligations and liabilities that relate to the operation of the Wellbores or the production of Substances, or that otherwise relate to the Properties and, in each case, arise from or relate to events occurring or conditions existing after the Effective Time or which accrue after the Effective Time. All such plugging, replugging, abandonment, removal, disposal, and restoration operations shall be in compliance with applicable laws and regulations and contracts, and shall be conducted in a good and workmanlike manner.

13. Final Accounting.

13.1. Settlement Statement.

(a) As soon as practical and, in any event, no later than one hundred and twenty (120) calendar days after the Closing Date, Seller shall prepare and deliver to Buyer a statement (the “Final Settlement Statement”) setting forth the adjustments to the Purchase Price in accordance with Section 2.2, other than Title Adjustment Amounts not

-19-

yet determined pursuant to Annex I. The Final Settlement Statement shall be prepared in accordance with this Agreement and on a basis consistent with the preparation of the Closing Statement as described in Section 2.3, and shall set forth Seller’s calculation of the Seller’s Credits, Buyer’s Credits and the Adjusted Purchase Price.

(b) Following the delivery of the Final Settlement Statement, Seller shall afford Buyer the opportunity to examine the Final Settlement Statement and Seller’s calculation of the Seller’s Credits, Buyer’s Credits and the Adjusted Purchase Price, and such supporting schedules, analyses, workpapers, including the audit workpapers and other underlying records or documentation, as are reasonably necessary and appropriate in connection with such review. Seller shall cooperate fully and promptly with the Buyer in such examination, including responding to questions asked by Buyer, and Seller shall make available to Buyer any records under Seller’s reasonable control that are requested by the Buyer in connection with such review.

(c) If, within 30 days following delivery of the Final Settlement Statement to Buyer, Buyer has not delivered to Seller written notice (the “Objection Notice”) of Buyer’s objections to the Final Settlement Statement or Seller’s calculation of Seller’s Credits, Buyer’s Credits and/or the Adjusted Purchase Price (which Objection Notice must contain a statement describing in reasonable detail the basis of such objections), then Seller’s Credits, Buyer’s Credits and/or the Adjusted Purchase Price as set forth in such Final Settlement Statement shall be deemed final and conclusive. In addition, any of Seller’s calculations of Seller’s Credits, Buyer’s Credits and/or the Adjusted Purchase Price as set forth in the Final Settlement Statement which are not objected to in the Objection Notice shall be deemed final and conclusive.

(d) If Buyer delivers the Objection Notice within such 30-day period, then Seller and Buyer shall endeavor in good faith to resolve the objections of Buyer set forth in the Objection Notice for a period not to exceed 15 days from the date of delivery of the Objection Notice. If at the end of the 15-day period there are any objections that remain in dispute, then the remaining objections in dispute shall be submitted for resolution to a “big four” accounting firm to be selected jointly by the Seller and Buyer within the following five days or, if the Seller and Buyer are unable to mutually agree within such five-day period, such accounting firm shall be Ernst & Young (such jointly selected accounting firm or Ernst & Young, the “Referee”). In connection with the engagement of the Referee, each of Buyer and Seller shall execute any engagement, indemnity, and other agreement as the Referee shall require as a condition to such engagement. If Ernst & Young is unable or unwilling to serve as the Referee and the parties are unable to agree upon the designation of a person as substitute arbitrator, then Seller or Buyer, or both of them, may in writing request the Judge of the United States District Court for the Southern District of Texas senior in term of service to appoint the substitute arbitrator. Notwithstanding the foregoing, any dispute regarding the existence of a Title Defect or any Title Adjustment Amount shall be determined in accordance with the procedures set forth in Annex I and any dispute regarding the existence of an Adverse Environmental Condition or any Remediation Value shall be determined in accordance with the procedures set forth in Annex II.

-20-

(e) The Referee shall determine such items of Seller’s Credits, Buyer’s Credits and the calculation of the Adjusted Purchase Price as are disputed within 30 days after the objections that remain in dispute are submitted to it.

(f) If any objections are submitted to the Referee for resolution, (A) each of Buyer and Seller shall furnish to the Referee such workpapers and other documents and information relating to such objections as the Referee may request and are available to that party or its Affiliates (or its independent public accountants) and will be afforded the opportunity to present to the Referee any material relating to the determination of the matters in dispute and to discuss such determination with the Referee prior to any written notice of determination hereunder being delivered by the Referee; (B) to the extent that a value has been assigned by Buyer or Seller to any item subject to Buyer’s objection that is submitted to the Referee, the Referee shall not assign a value to such objection that is greater than the greatest value for such objection claimed by either party or less than the smallest value for such objection claimed by either party; (C) the determination by the Referee of items of Seller’s Credits, Buyer’s Credits and the calculation of the Adjusted Purchase Price, as applicable, as set forth in a written notice delivered to Seller and Buyer by the Referee, shall be made in accordance with this Agreement and shall be binding and conclusive on the parties and shall constitute an arbitral award that is final, binding and unappealable and upon which a judgment may be entered by a court having jurisdiction thereof; (D) the fees and expenses of the Referee shall be paid by and apportioned between Buyer and Seller based on the aggregate dollar amount in dispute and the relative recovery as determined by the Referee of Seller and Buyer, respectively; and (E) notwithstanding anything in this Agreement to the contrary, each Party hereto shall bear its own costs and expenses in connection with the resolution of any objections to the calculations set forth in the Final Settlement Statement.

13.2. Payments.

13.2.1 If the Closing Amount is greater than the final Adjusted Purchase Price, then Seller shall pay to Buyer the amount of such excess within five (5) Business Days of the determination of the final Adjusted Purchase Price in accordance with Section 13.1.

13.2.2 If the final Adjusted Purchase Price is greater than the Closing Amount, then Buyer shall pay such difference to Seller within five (5) Business Days of the determination of the final Adjusted Purchase Price in accordance with Section 13.1.

13.3. No Duplicative Effect; Methodologies. The provisions of Section 13.1 shall apply in such a manner so as not to give the components and calculations duplicative effect to any item of adjustment and, except as otherwise expressly provided in this Agreement or in the Closing Statement, the parties covenant and agree that no amount shall be (or is intended to be) included, in whole or in part (either as an increase or reduction) more than once in the calculation of (including any component of) capital expenditures, or operating expenses or any other calculated amount pursuant to this Agreement if the effect of such additional inclusion (either as an increase or reduction) would be to cause such amount to be overstated or understated for purposes of such calculation. The parties acknowledge and agree that, if there is a conflict between a determination, calculation or methodology set forth in the Closing Statement or the

-21-

definitions contained in this Agreement, as applicable, on the one hand, and those provided by GAAP, on the other hand, (a) the determination, calculation or methodology set forth in the Closing Statement or the definitions contained in this Agreement, as applicable, shall control to the extent that the matter is included in the Closing Statement or the definitions contained in this Agreement, as applicable, as a line item or specific adjustment and (b) the determination, calculation or methodology prescribed by GAAP shall control to the extent the matter is not so addressed in the Closing Statement or the definitions contained in this Agreement, as applicable, or requires reclassification as an asset or liability to be included in a line item or specific adjustment.

13.4. Respective Ownership. Seller shall own and receive (or receive credit in the Closing Statement or the Final Settlement Statement, as applicable, for) all proceeds from the sale of hydrocarbons produced from or allocable to the Properties prior to the Effective Time, and shall also receive (or receive credit in the Closing Statement or the Final Settlement Statement, as applicable, for) and hold the right to receive all other revenues, proceeds and benefits attributable to the Properties relating to all periods before the Effective Time. Buyer shall receive (or receive credit in the Closing Statement or the Final Settlement Statement, as applicable, for) all proceeds from the sale of hydrocarbons produced from or allocable to the Properties from and after the Effective Time and shall also receive (or receive credit in the Closing Statement or the Final Settlement Statement, as applicable, for) and hold the right to receive all other revenues, proceeds and benefits attributable to the Properties which relate to all periods from and after the Effective Time. Notwithstanding anything contained in this Section 13 to the contrary if, at any time, Buyer shall receive any revenues for which the Purchase Price was decreased, or revenues which belong to Seller, as provided above, Buyer shall promptly remit same in immediately available funds to Seller. Likewise, if Seller shall for any reason receive any revenue for which the Purchase Price was increased, or revenues which belong to Buyer, as provided above, Seller shall promptly remit same in immediately available funds to Buyer. Except as otherwise provided in this Agreement, any costs and expenses, including taxes (other than income tax) relating to the Properties which are not reflected in the Final Settlement Statement shall be treated as follows: All costs and expenses relating to the Properties for the period of time prior to the Effective Time shall be the sole obligation of Seller and Seller shall promptly pay, or if paid by Buyer, promptly reimburse Buyer in immediately available funds for the same; and all costs and expenses relating to the Properties for the period of time on or after the Effective Time shall be the sole obligation of Buyer and Buyer shall promptly pay, or if paid by Seller, promptly reimburse Seller in immediately available funds for the same.

14. Survival and Indemnification.

14.4. Indemnification by Buyer. After the Closing, Buyer shall assume, be responsible for, shall pay on a current basis, and shall indemnify, save, hold harmless, discharge and release Seller, its affiliates, its and their successors and permitted assigns, and all of their respective members, directors, officers, employees, agents and representatives (collectively, “Seller Indemnified Parties”) from and against any and all Liabilities arising from, based upon, related to or associated with (a) any act, omission, event, condition or circumstance involving or relating to the Properties occurring or existing after the Effective Time; (b) all Assumed Obligations; (c) any brokers’ or finders’ fees or commissions arising with respect to brokers or finders retained or engaged by any person other than Seller and resulting from or relating to the transactions contemplated in this Agreement; (d) the inaccuracy of any representation or warranty of Buyer set forth in this Agreement or in any other agreement, instrument, document or certificate executed or delivered in connection with this Agreement (as limited by the express terms of any representation or warranty); and (e) the breach of, or failure to perform or satisfy any of the covenants of Buyer set forth in this Agreement or in any other agreement, instrument, document or certificate executed or delivered in connection with this Agreement.

14.5. Liability Limitations.

14.5.1 The liability of Seller (i) for the inaccuracy of any representation or warranty, (ii) for the breach of any covenant, (iii) for indemnity under the terms of this Agreement or (iv) otherwise in connection with the transactions contemplated in this Agreement, shall be limited to claims for indemnification pursuant to Section 14.3 for which a Buyer Indemnified Party delivers written notice to Seller on or before the date that ends 6 months following the Closing Date (the “Claim Period”); provided, however, that a Buyer Indemnified Party may deliver notice to Seller (x) at any time after Closing with respect to a breach of Seller’s representations and warranties in Sections 3.1 through 3.3; and (y) at any time during the applicable statute of limitations period with respect to a breach of Seller’s representations and

-23-

warranties in Section 3.9(b), in which case any liability of Seller for any of the foregoing shall only survive beyond the Claim Period to the extent asserted in a notice delivered during the Claim Period. Furthermore, and notwithstanding anything contained herein to the contrary, any claims for a breach of any of Seller’s representations and warranties in Sections 3.11 through 3.14 must be asserted by Buyer prior to Closing and Buyer’s sole recourse with regard thereto shall be to terminate this Agreement pursuant to Section 11.1(c). In no event shall any claims for a breach of any of Seller’s representations and warranties in Sections 3.11 through 3.14 survive Closing. Any notice under this Section 14.5.1 shall state the facts known to the Buyer Indemnified Party that give rise to such notice in sufficient detail to allow Seller to evaluate the assertion.

14.5.2

(a) None of the Buyer Indemnified Parties shall be entitled to assert any claim for indemnification hereunder, or to otherwise seek any damages or other remedies for or in connection therewith, unless the Liability attributable to the claim is in excess of $50,000 (“Claim Threshold”). The limitations in this Section shall not apply, however, to the obligations of Seller under Sections 12.1, 13.1, 13.2, 13.4 and 19 or to claims for indemnification with respect to a breach of Seller’s representations and warranties under Section 3.9(b).

(b) Additionally, none of the Buyer Indemnified Parties shall be entitled to assert any claim for indemnification hereunder, or to otherwise seek any damages or other remedies for or in connection therewith, until the aggregate amount of all Liabilities in excess of the Claim Threshold exceeds one and one-half percent (1.5%) of the Purchase Price, and then only to the extent of such excess. The limitations in this Section shall not apply, however, to the obligations of Seller under Sections 12.1, 13.1, 13.2, 13.4 and 19 or to claims for indemnification with respect to a breach of Seller’s representations and warranties under Section 3.9(b).

(c) Seller shall not be liable for any claims for indemnification hereunder in any amount exceeding in the aggregate twenty percent (20%) of the Purchase Price; provided, however, that as to claims for indemnification with respect to breaches of Seller’s representations and warranties in Sections 3.1 through 3.3 and Section 3.9(b), Seller shall not be liable for any amount exceeding the Purchase Price and for claims for breach of Seller’s special warranty of title in the Assignment Seller shall not be liable for any amount exceeding the Allocated Value of the Wellbore affected by such breach.

14.5.3 The amount of any Liabilities for which any of the Buyer Indemnified Parties or Seller Indemnified Parties is entitled to indemnification or other compensation under this Agreement or in connection with or with respect to the transactions contemplated in this Agreement shall be reduced by any corresponding (i) tax benefit created or generated or (ii) insurance proceeds realized or that could reasonably be expected to be realized by such party if a claim were properly pursued under the relevant insurance arrangements.

-24-

14.5.4 None of the Buyer Indemnified Parties nor the Seller Indemnified Parties shall be entitled to recover from Seller or Buyer, respectively, for any losses, costs, expenses, or damages arising under this Agreement or in connection with or with respect to the transactions contemplated in this Agreement, any amount in excess of the actual compensatory damages, court costs and reasonable attorney fees, suffered by such party.

14.5.6 No person entitled to indemnification hereunder or otherwise to damages in connection with or with respect to the transactions contemplated in this Agreement shall settle, compromise or take any other action with respect to any claim, demand, assertion of liability or legal proceeding that could prejudice or otherwise adversely impact the ability of the person providing such indemnification or potentially liable for such damages to defend or otherwise settle or compromise with respect to such claim, demand, assertion of liability or legal proceeding.

14.5.7 Seller and Buyer acknowledge that the payment of money, as limited by the terms of this Agreement, shall be adequate compensation for breach of any representation, warranty, covenant or agreement contained herein or for any other claim arising in connection with or with respect to the transactions contemplated in this Agreement which is not asserted by Buyer prior to the Closing.

-25-

reasonable steps to mitigate all losses, costs, expenses and damages after becoming aware of any event or circumstance that could reasonably be expected to give rise to any losses, costs, expenses and damages that are indemnifiable or recoverable hereunder or in connection herewith.

14.5.10 Seller shall not have any obligation or liability under this Agreement or in connection with or with respect to the transactions contemplated in this Agreement for any breach, misrepresentation or noncompliance with respect to any representation, warranty, covenant, indemnity or obligation (i) if such breach, misrepresentation or noncompliance shall have been waived in writing by Buyer or (ii) if Buyer had actual knowledge of the relevant facts at or before Closing.

14.6. Waiver of Consumer Rights. BUYER HEREBY WAIVES THE PROVISIONS OF THE TEXAS DECEPTIVE TRADE PRACTICES ACT, CHAPTER 17, SUBCHAPTER E, SECTIONS 17.41 THROUGH 17.63, INCLUSIVE (OTHER THAN SECTION 17.555, WHICH IS NOT WAIVED), OF THE TEXAS BUSINESS AND COMMERCE CODE (“DTPA”), A LAW THAT GIVES CONSUMERS SPECIAL RIGHTS AND PROTECTIONS. AFTER CONSULTATION WITH AN ATTORNEY OF ITS OWN SELECTION, BUYER VOLUNTARILY CONSENTS TO THIS WAIVER. TO EVIDENCE ITS ABILITY TO GRANT SUCH WAIVER, BUYER REPRESENTS TO SELLER THAT (I) IT IS NOT IN A SIGNIFICANTLY DISPARATE BARGAINING POSITION; (II) IT IS REPRESENTED BY LEGAL COUNSEL IN ENTERING INTO THIS AGREEMENT; AND (III) SUCH LEGAL COUNSEL WAS NOT DIRECTLY OR INDIRECTLY IDENTIFIED, SUGGESTED, OR SELECTED BY SELLER OR AN AGENT OF SELLER.

Exhibit 2.3

GUARANTY AGREEMENT

This Guaranty Agreement (this “Agreement”), dated as of March 31, 2008, is made by and among Constellation Energy Commodities Group, Inc., a Delaware corporation (“Guarantor”), and CEP Mid-Continent LLC, a Delaware limited liability company (“CEP MidCon”).

WITNESSETH:

WHEREAS, Cola Resources LLC, a Delaware limited liability company and an affiliate of Guarantor (the “Seller”), has entered into that certain Agreement for Purchase and Sale dated February 19, 2008 (as it may be amended from time to time, the “Purchase Agreement”) with CEP MidCon, pursuant to which Seller will sell and CEP MidCon will acquire certain Properties identified in the Purchase Agreement. All capitalized terms used herein which are not otherwise defined herein shall have the meaning attributed to them in the Purchase Agreement.

WHEREAS, Guarantor will receive substantial and direct benefits from the extensions of credit contemplated by the Purchase Agreement and has agreed to enter into this Agreement to provide assurance for the performance of certain of Seller’s obligations in connection with the Purchase Agreement and to induce CEP MidCon to enter into the Purchase Agreement.

WHEREAS, the execution and delivery of this Agreement is a condition to CEP MidCon’s obligation to close under the terms of the Purchase Agreement.

NOW, THEREFORE, in consideration of the premises and other good and valuable consideration, the adequacy, receipt and sufficiency of which are hereby acknowledged, Guarantor hereby agrees as follows:

ARTICLE I

GUARANTY

Section 1.1 Guaranty. Subject to Sections 1.2 and 1.3 hereof, Guarantor hereby unconditionally, absolutely and irrevocably guarantees the punctual payment when-due of Seller’s payment obligations, if any, arising under Section 14.3 of the Purchase Agreement (subject to the limitations in Section 14.5 of the Purchase Agreement) (the “Indemnity Obligations”) and (ii) Annex I of the Purchase Agreement (the “Title Defect Obligations” and collectively with the Indemnity Obligations, the “Guaranteed Obligations”); provided, however, that the maximum liability of Guarantor hereunder, regardless of any amendment or modification to the Purchase Agreement, is limited to (a) for all Indemnity Obligations, the sum of $10,664,900.00 and (b) for all Title Defect Claims, the sum of $ 9,178,873.00. The maximum liability of Guarantor for Title Defect Obligations is calculated to approximate the aggregate of that portion, if any, of the Allocated Value of each Wellbore allocable to any Lease as to which Seller has not received recorded assignments of its interest as of the Closing Date, less the estimated

sum of proceeds due Seller for periods prior to the Effective Time attributable to Wellbores which are not on pay status as of the Closing Date. Accordingly, the maximum liability of Guarantor for Title Defect Obligations shall adjust proportionately over time as CEP MidCon receives and records assignments of its interests or receives proceeds for Wellbores previously not on pay status based on the original calculations establishing Guarantor’s maximum liability. Guarantor’s obligations and liability under this Agreement shall be limited to payment obligations only and Guarantor shall have no obligation to perform under the Purchase Agreement, including, without limitation, to sell, deliver, supply or transport gas, electricity or any other commodity.

Section 1.2 Certain Defenses. CEP MidCon agrees that, notwithstanding anything contained herein to the contrary, Guarantor shall not be obligated to pay the Guaranteed Obligations hereunder to the extent that the Seller is not required to pay the Guaranteed Obligations as a result of any right of offset, counterclaim or other defense available to the Seller with respect to the Guaranteed Obligations (collectively, a “Seller Defense”). In furtherance thereof, Guarantor shall be entitled to assert, as a valid defense to payment of the Guaranteed Obligations, any Seller Defense to the same extent that any such Seller Defense could be asserted by Seller in any action brought to enforce the Guaranteed Obligations against the Seller.

Section 1.3 Termination. This Agreement and all obligations hereunder shall terminate (i) as to the Indemnity Obligations, six (6) months following the Closing Date under the Purchase Agreement as to any Liabilities not asserted by the Buyer Indemnified Parties against Seller prior to such six (6) month period and (ii) as to the Title Defect Obligations, thirty (30) days after satisfaction of Seller’s payment obligations to Buyer arising under Annex I of the Purchase Agreement.

Section 1.4 Certain Waivers.

Guarantor hereby waives:

(a) notice of amendment or other modification of the Purchase Agreement;

(b) notice of any extension of time or other modification of the payment terms for any sums due and payable by Seller to CEP MidCon in connection with the Purchase Agreement;

(c) notice of any defaults by or disputes between Seller and CEP MidCon with respect to performance of Seller’s payment obligations under the Purchase and Sale Agreement; and

(d) notice of presentment, demand for payment, default, dishonor, protest or notice of protest with respect to this Agreement.

Section 1.5 Other Matters.

(a) Guarantor acknowledges that amendment or other modification of the Purchase Agreement shall not discharge or otherwise affect the liability of the Guarantor with

respect thereto under this Agreement. Guarantor agrees that Guarantor’s obligations under this Agreement are unconditional, irrespective of any circumstance other than payment or satisfaction that might otherwise constitute a legal or equitable discharge of a guarantor.

(b) CEP MidCon is not required to proceed first against Seller or any other person or entity before resorting to Guarantor for payment under this Agreement.

(c) Guarantor shall be subrogated to all rights of CEP MidCon against Seller in respect of any amounts paid by Guarantor pursuant to this Agreement; provided that Guarantor waives any rights it may acquire by way of subrogation under this Agreement by any payment made hereunder or otherwise (including, without limitation, any statutory rights of subrogation under Section 509 of the Bankruptcy Code, 11 U.S.C. § 509, or otherwise), reimbursement, exoneration, contribution, or indemnification until all of the Guaranteed Obligations shall have been irrevocably paid to CEP MidCon in full. If (a) the Guarantor shall perform and shall make payment to CEP MidCon of all or any part of the Guaranteed Obligations and (b) all the Guaranteed Obligations shall have been paid in full, CEP MidCon shall, at the Guarantor’s request, execute and deliver to the Guarantor appropriate documents necessary to evidence the transfer by subrogation to the Guarantor of any interest in the Guaranteed Obligations resulting from such payment by Guarantor.

(d) Guarantor agrees that except as expressly set forth herein, it will remain bound upon this Agreement notwithstanding any defenses which, pursuant to the laws of suretyship, would otherwise relieve a guarantor of its obligations under a guaranty. Notwithstanding the foregoing, Guarantor does reserve the right to assert defenses which Seller may have to payment of any Guaranteed Obligation, other than defenses arising from the bankruptcy or insolvency of Seller and other defenses expressly waived hereby.

ARTICLE II

MISCELLANEOUS

Section 2.1 Amendments, Etc. No amendment, supplement, modification or waiver of any provision of this Agreement nor consent to any departure by Guarantor therefrom shall be effective unless the same shall be in writing and signed by Guarantor and CEP MidCon.

Section 2.2 Notices. (a) All notices, requests, demands and other communications which are required or may be given under this Agreement shall be in writing and shall be deemed to have been duly given when received if personally delivered when transmitted if transmitted by telecopy, electronic or digital transmission method; the day after it is sent, if sent for next day delivery to a domestic address by recognized overnight delivery service; and upon receipt, if sent by certified or registered mail, return receipt requested.

ARTICLE II

THE CREDITS

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

Section 2.02 Loans and Borrowings.

(a) Borrowings; Several Obligations. Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance with their respective

22

Loan Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Loan Commitments are several and no Lender shall be responsible for any other Lender’s failure to make Loans as required.

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

(c) Minimum Amounts; Limitation on Number of Borrowings. At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $500,000 and not less than $1,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $250,000 and not less than $1,000,000; provided that an ABR Borrowing may be in an aggregate amount that is equal to the entire unused balance of the Aggregate Maximum Credit Amount or that is required to finance the reimbursement of a Letter of Credit Disbursement as contemplated by Section 2.08(e). Borrowings of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of twelve (12) Eurodollar Borrowings outstanding. Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

(d) Notes. The Loans made by each Lender shall, if requested by such Lender in writing, be evidenced by a single promissory note of the Borrower (except in the case of an increase of a Maximum Credit Amount of the Lenders in accordance with Section 2.09, which may be evidenced by one or more promissory notes of the Borrower) in substantially the form of Exhibit A, dated, in the case of (i) any Lender party hereto as of the date of this Agreement, as of the date of this Agreement or (ii) any Lender that becomes a party hereto pursuant to an Assignment and Assumption, as of the effective date of the Assignment and Assumption, payable to the order of such Lender in a principal amount equal to its Maximum Credit Amount as in effect on such date, and otherwise duly completed. In the event that any Lender’s Maximum Credit Amount increases or decreases for any reason (whether pursuant to Section 2.06, Section 2.09, Section 12.04(b) or otherwise), the Borrower shall deliver or cause to be delivered 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 the affected Lender shall deliver the Note being replaced to the Borrower immediately. The date, amount, interest rate and 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.

23

Section 2.03 Requests for Borrowings. To request a Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone not later than Noon, New York time, (i) three (3) Business Days before the date of the proposed Borrowing, in the case of Eurodollar Borrowings, or (ii) on the same Business Day, in the case of ABR Borrowings. Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request in the form attached hereto as Exhibit 2.03. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02:

(i) the aggregate amount of the requested Borrowing;

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

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

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

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

In the case of Eurodollar Borrowings, if no Interest Period is specified with respect to any requested Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Each Borrowing Request shall constitute a representation that the amount of the requested Borrowing shall not cause the Total Revolving Credit Exposures to exceed the lesser of the Aggregate Maximum Credit Amount and the then effective Borrowing Base.

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

Section 2.04 Interest Elections.

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

(b) Interest Election Requests. To make an election pursuant to this Section 2.04, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03. 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 in the form attached hereto as Exhibit 2.04(b) and signed by the Borrower.

24

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

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

(iii) the Interest Period to be applicable to such Borrowing after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

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

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

(e) Effect of Failure to Deliver Timely Interest Election Request and Events of Default and Borrowing Base Deficiencies on Interest Election. If the Borrower fails to deliver a timely Interest Election Request with respect to a 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 Loan having an Interest Period of one month. Notwithstanding any contrary provision hereof, if an Event of Default or a Borrowing Base Deficiency has occurred and is continuing, then no outstanding Borrowing may be continued (and any Interest Election Request that requests the continuation of any Borrowing shall be ineffective).

Section 2.05 Funding of Borrowing.

(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 2:00 p.m., New York time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower and designated by the Borrower in the applicable Borrowing Request; provided that Loans made to finance the reimbursement of a Letter of Credit Disbursement as provided in Section 2.08(e) shall be remitted by the Administrative Agent to the Issuer that made such Letter of Credit Disbursement. Nothing herein shall be deemed to obligate any Lender to

25

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 Advance 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 Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

Section 2.06 Termination and Reduction of Aggregate Maximum Credit Amount.

(a) Scheduled Termination of Loan Commitments. Unless previously terminated, the Loan Commitments shall terminate on the Maturity Date. If at any time the Aggregate Maximum Credit Amount or the Borrowing Base is terminated or reduced to zero, then the Loan 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 Amount; provided that (A) each reduction of the Aggregate Maximum Credit Amount 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 Amount if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 3.03(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 Amount under Section 2.06(b)(i) at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section 2.06(b)(ii) shall be irrevocable. Any termination or reduction of the Aggregate Maximum Credit Amount shall be permanent and may not be reinstated. Each reduction of the Aggregate Maximum Credit Amount shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage.

26

Section 2.07 Borrowing Base.

(a) For the period from and including the Closing Date to but excluding the date of the first determination of the Borrowing Base pursuant to the further provisions of this Section 2.07, the initial amount of the Borrowing Base has been set by the Administrative Agent and acknowledged by the Borrower and agreed to by the Lenders to be $150,000,000 (the “Base Amount”). For each and every determination or redetermination of the Borrowing Base under this Agreement, the Borrowing Base shall be determined or redetermined based on the oil and gas reserves attributable to the Oil and Gas Properties of the Borrower and its Subsidiaries not located in the State of Alabama.

(b) Promptly after January 1 of each calendar year, commencing January 1, 2008, and in any event prior to March 31 of each calendar year (commencing March 31, 2008), the Borrower shall furnish to the Administrative Agent a Reserve Report in form and substance reasonably satisfactory to the Administrative Agent, prepared by an Approved Engineer, which Reserve Report shall be dated as of January 1 of such calendar year together with additional data concerning pricing, hedging, quantities and purchasers of production, and other information and engineering and geological data as the Administrative Agent may reasonably request. Within fifteen (15) days after receipt of such Reserve Report and all such information, the Administrative Agent shall make an initial determination of the new Borrowing Base (the “Proposed Borrowing Base”), which for purposes of this Section 2.07(b) is the semi-annual determination described in Section 2.07(c), and upon such initial determination shall promptly notify the Lenders in writing of its initial determination of the Proposed Borrowing Base. Such initial determinations made by the Administrative Agent shall be so made by the Administrative Agent in the exercise of its sole discretion in accordance with the Administrative Agent’s customary practices and standards for oil and gas lending as they exist at the particular time, and may include a consideration of the value of the Oil and Gas Properties that are subject to legal, valid and enforceable mortgage liens held by the Administrative Agent for the ratable benefit of the Lenders. In no event shall the Proposed Borrowing Base exceed the Aggregate Maximum Credit Amount of the Lenders. The Required Lenders shall approve or reject the Administrative Agent’s initial determinations of the Proposed Borrowing Base by written notice to the Administrative Agent within fifteen (15) days of the Administrative Agent’s notification of its initial determinations; provided, however, that failure by any Lender to confirm in writing the Administrative Agent’s determination of the Proposed Borrowing Base shall be deemed an approval of the Proposed Borrowing Base. If the Required Lenders fail to approve any such determination of the Proposed Borrowing Base made by the Administrative Agent hereunder in such fifteen (15) day period, then the Administrative Agent shall poll the Lenders to ascertain the highest Proposed Borrowing Base then acceptable to the Required Lenders for purposes of this Section 2.07(b) and, subject to the last sentence of this Section 2.07(b), such amounts shall become the new Borrowing Base, effective on the date specified in this Section 2.07. Until such approval or deemed approval, the Borrowing Base in effect before the Proposed Borrowing Base shall remain in effect. Upon agreement by the Administrative Agent and the Required Lenders of the new Borrowing Base, the Administrative Agent shall, by written notice to the Borrower and the Lenders, designate the new Borrowing Base available to the Borrower. Such designation

27

shall be effective as of the Business Day specified in such written notice (or, if no effective date is specified in such written notice, the next Business Day following delivery of such written notice), and such new Borrowing Base shall remain in effect until the next determination or redetermination of the Borrowing Base in accordance with this Agreement. Anything herein contained to the contrary notwithstanding, any determination or redetermination of the Borrowing Base resulting in any increase of the Borrowing Base in effect immediately prior to such determination or redetermination shall require the approval of all the Lenders in their sole discretion in accordance with their respective customary practices and standards for oil and gas lending as they exist at the particular time, and may include a consideration of the value of the Oil and Gas Properties that are subject to legal, valid and enforceable mortgage liens held by the Administrative Agent for the ratable benefit of the Lenders.

(c) In addition, within ninety (90) days after each June 30, commencing June 30, 2008, the Borrower shall furnish to the Administrative Agent a Reserve Report in form and substance satisfactory to the Administrative Agent, prepared by the Borrower’s petroleum engineers or on behalf of Borrower by petroleum engineers under the Management Services Agreement, which report shall be dated as of July 1 of such calendar year together with additional data concerning pricing, hedging, quantities and purchasers of production, and other information and engineering and geological data as the Administrative Agent may reasonably request. Within fifteen (15) days after receipt of such Reserve Report and all such information, the Administrative Agent shall make an initial determination of a Proposed Borrowing Base, and upon such initial determination shall promptly notify the Lenders in writing of initial determination of the Proposed Borrowing Base. Such initial determination shall be made in the same manner and be subject to the same approvals as prescribed above with respect to the annual review, and likewise the Administrative Agent shall communicate the results of such initial determinations to the Lenders. The Required Lenders shall approve such determinations of the Proposed Borrowing Base by written notice to the Administrative Agent within fifteen (15) days of the giving of notice of such determinations by the Administrative Agent to such Lenders; provided, however, that failure by any Lender to confirm in writing the Administrative Agent’s determination of the Proposed Borrowing Base shall be deemed an approval of the Proposed Borrowing Base. If the Required Lenders fail to approve any such determination of the Proposed Borrowing Base made by the Administrative Agent hereunder in such fifteen (15) day period, then the Administrative Agent shall poll the Lenders to ascertain the highest Proposed Borrowing Base then acceptable to the Required Lenders for purposes of this Section 2.07(c) and, subject to the last sentence of this Section 2.07(c), such amounts shall become the new Borrowing Base, effective on the date specified in this Section 2.07. Upon agreement by the Administrative Agent and the Required Lenders of the amount of credit to be made available to the Borrower hereunder, the Administrative Agent shall, by written notice to the Borrower and the Lenders, designate the new Borrowing Base available to the Borrower. Such designation shall be effective as of the Business Day specified in such written notice (or, if no effective date is specified in such written notice, the next Business Day following delivery of such written notice) and such new Borrowing Base shall remain in effect until the next determination or redetermination of the Borrowing Base in accordance with this Agreement. Anything herein contained to the contrary notwithstanding, any determination or redetermination of the Borrowing Base resulting in any increase of the Borrowing Base in effect immediately prior to such determination or redetermination shall require the approval of all the Lenders in their sole

28

discretion in accordance with their respective customary practices and standards for oil and gas lending as they exist at the particular time, and may include a consideration of the value of the Oil and Gas Properties that are subject to legal, valid and enforceable mortgage liens held by the Administrative Agent for the ratable benefit of the Lenders.

(d) In addition to the foregoing scheduled annual and semi annual determinations of the Borrowing Base, the Required Lenders shall have the right to redetermine the Borrowing Base at their sole discretion at any time and from time to time but not more often than two (2) times every calendar year. If the Required Lenders shall elect to make a discretionary redetermination of the Borrowing Base pursuant to the provisions of this Section 2.07(d), the Borrower shall within thirty (30) days of receipt of a request therefor from the Administrative Agent, deliver to the Administrative Agent a Reserve Report in form and substance satisfactory to the Administrative Agent, prepared by the Borrower’s petroleum engineers containing information similar to the Reserve Reports delivered pursuant to Section 2.07(c), together with such updated engineering, production, operating and other data as the Administrative Agent, the Issuer or any Lender may reasonably request. The Administrative Agent shall have fifteen (15) days following receipt of such requested information to make an initial redetermination of the Borrowing Base, and the Administrative Agent and the Required Lenders shall approve and designate the new Borrowing Base in accordance with the procedures and standards described in Section 2.07(b).

(e) In addition to the foregoing determinations of the Borrowing Base, the Borrower may request a redetermination of the Borrowing Base at any time and from time to time but not more often than two (2) times every calendar year, by delivering a written request to the Administrative Agent, together with (a) an engineering fee in the aggregate amount of $2,500 for the account of the Administrative Agent in immediately available funds, and (b) a Reserve Report in form and substance satisfactory to the Administrative Agent, prepared by the Borrower’s petroleum engineers containing information similar to the Reserve Reports delivered pursuant to Section 2.07(c), together with such other updated engineering, production, operating and other data as the Administrative Agent, the Issuer or any Lender may reasonably request. Each such discretionary redetermination of the Borrowing Base shall be made in the same manner and in accordance with the procedures and standards set forth above by adjusting the Borrowing Base then in effect. The Administrative Agent shall have fifteen (15) days following receipt of such requested information to make an initial redetermination of the Borrowing Base, and the Administrative Agent and the Required Lenders shall approve and designate the new Borrowing Base in accordance with the procedures and standards described in Section 2.07(b).

(f) In addition to the Borrower’s right to request a discretionary Borrowing Base redetermination as set forth in Section 2.07(e), the Borrower may request a redetermination of the Borrowing Base at any time and from time to time upon the acquisition by the Borrower of (i) additional Oil and Gas Properties or (ii) a Person that owns Oil and Gas Properties, the purchase price of which shall represent at least 20% of the Borrowing Base then in effect, by delivering a written request to the Administrative Agent, together with (a) an engineering fee in the aggregate amount of $2,500 for the account of the Administrative Agent in immediately available funds, (b) a Reserve Report in form and substance satisfactory to the Administrative Agent with respect to Oil and Gas Properties represented in the existing Borrowing Base, prepared and delivered in accordance with Section 2.07(c), (c) a Reserve Report in form and

29

substance satisfactory to the Administrative Agent, with respect to Oil and Gas Properties acquired since the most recent redetermination of the Borrowing Base, prepared and delivered in accordance with Section 2.07(b), and (d) a most recent draft of the agreements by which the Borrower proposes to acquire such additional Oil and Gas Properties or such Person that owns such Oil and Gas Properties, which drafts shall be supplemented upon execution by true and complete executed copies of the same. Each such redetermination of the Borrowing Base under this Section 2.07(f) shall be made in the same manner and in accordance with the procedures and standards set forth above by adjusting the Borrowing Base then in effect. The Administrative Agent shall have fifteen (15) days following receipt of such requested information to make an initial redetermination of the Borrowing Base, and the Administrative Agent and the Required Lenders shall approve and designate the new Borrowing Base in accordance with the procedures and standards described in Section 2.07(b). The Borrower, Administrative Agent and Lenders agree that the Borrowing Base may be increased by an amount up to $25,000,000 above the Base Amount, as requested by Borrower, upon Administrative Agent’s receipt of executed copies of the purchase agreement and conveyances pursuant to which Borrower or its Subsidiaries acquired the Oil and Gas Properties of CoLa Resources LLC included in the reserve report received by Administrative Agent dated                         , 2008; provided that such increase in the Borrowing Base is subject to the requirements of Section 8.12 and 8.13.

(g) Notwithstanding anything to the contrary contained herein, upon the consummation of a Material Swap Transaction, the Required Lenders shall have the right to redetermine the Borrowing Base using information available to them, and the redetermined Borrowing Base shall become the new Borrowing Base immediately upon notice by the Administrative Agent to the Borrower, effective and applicable to the Borrower, the Administrative Agent, and each Lender on such date until the next redetermination or modification thereof hereunder (subject to the reduction described in Section 2.07(i)). The Borrowing Base will also be redetermined or adjusted in accordance with the provisions of Section 8.12(c) or Section 9.12(d).

(h) With the delivery of each Reserve Report, the Borrower shall provide to the Administrative Agent a certificate from a Responsible Officer certifying that, to the best of such Responsible Officer’s knowledge and in all material respects: (i) the information contained in each such Reserve Report and any other information delivered in connection therewith is true and correct, (ii) the Borrower or the Guarantors owns good and defensible title to the Oil and Gas Properties evaluated in each such Reserve Report and such Properties are free of all Liens except for Liens permitted by Section 9.03, (iii) except as set forth on an exhibit to the certificate, on a net basis there are no gas imbalances, take or pay or other prepayments in excess of the volume specified in Section 7.20 with respect to their Oil and Gas Properties evaluated in such Reserve Report that would require the Borrower or any of its Subsidiaries to deliver Hydrocarbons either generally or produced from such Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor, (iv) none of their Oil and Gas Properties have been sold since the date of the last Borrowing Base determination except as set forth on an exhibit to the certificate, which certificate shall list all of its Oil and Gas Properties sold and in such detail as reasonably required by the Administrative Agent, (v) attached to the certificate is a list of all marketing agreements entered into subsequent to the later of the date hereof or the most recently delivered Reserve Report that the Borrower could reasonably be expected to have been obligated

30

to list on Schedule 7.20 had such agreement been in effect on the date hereof, (vi) attached thereto is a schedule of the Oil and Gas Properties evaluated by such Reserve Report that are Mortgaged Properties and demonstrating the percentage of the present value that such Mortgaged Properties represent, (vii) the outstanding amount of the Debt of the Borrower or any of its Subsidiaries permitted to be incurred pursuant to Section 9.02(e), and (viii) the Alabama Total Revolving Credit Exposure.

(i) Notwithstanding anything herein the contrary, in the event that the Borrower does not furnish any required Reserve Report within ten (10) days of date the required herein, the Administrative Agent and the Required Lenders may nonetheless designate the Borrowing Base from time to time thereafter until the Administrative Agent receives such Reserve Report, whereupon the Administrative Agent and the Required Lenders or all Lenders, as applicable, shall designate a new Borrowing Base in accordance with the general procedures outlined in Section 2.07(b).

(j) Notwithstanding the requirements of Section 12.02(b)(ii), any decrease of the Borrowing Base resulting solely as a result of any incurrence of Debt incurred by Borrower or any of its Subsidiaries shall become effective upon the Administrative Agent’s notice thereof to the Borrower and the Lenders, and shall not require any approval of the Lenders or the Required Lenders.

Section 2.08 Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request any Issuer to issue Letters of Credit for its own account or for the account of any of its Subsidiaries, in a form reasonably acceptable to the Administrative Agent and such Issuer, 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 Letter of Credit Agreement submitted by the Borrower to, or entered into by the Borrower with, an Issuer relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

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

31

(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 Letter of Credit Exposure shall not exceed the Letter of Credit Commitment and (ii) the Total Revolving Credit Exposures shall not exceed the lesser of the Aggregate Maximum Credit Amount and the then effective Borrowing Base.

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

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is five Business Days prior to the Maturity Date.

(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 Issuer that issues such Letter of Credit or the Lenders, each Issuer that issues a Letter of Credit hereunder hereby grants to each Lender, and each Lender hereby acquires from such Issuer, 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 Issuer that issues a Letter of Credit hereunder, such Lender’s Applicable Percentage of each Letter of Credit Disbursement made by such Issuer and not reimbursed by the Borrower on the date due as provided in Section 2.08(e), or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this Section 2.08(d) in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default, the existence of a Borrowing Base Deficiency or reduction or termination of the Loan Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

32

(e) Reimbursement. If any Issuer shall make any Letter of Credit Disbursement in respect of a Letter of Credit issued by such Issuer, the Borrower shall reimburse such Letter of Credit Disbursement by paying to the Administrative Agent for the account of the applicable Issuer at the Alternate Base Rate plus the Applicable Margin, an amount equal to such Letter of Credit Disbursement not later than 12:00 p.m., New York time, on the day such Letter of Credit Disbursement is made, if the Borrower shall have received notice of such Letter of Credit Disbursement prior to 10:00 a.m., New York 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 2:00 p.m., New York time, on the next succeeding Business Day; provided that if such Letter of Credit Disbursement is not less than $1,000,000, the Borrower shall, subject to the conditions to Borrowing set forth herein, be deemed to have requested, and the Borrower does hereby request under such circumstances, that such payment be financed with an ABR Loan in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Loan. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable Letter of Credit 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 Issuer 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 Issuer 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 Issuer, then to such Lenders and such Issuer as their interests may appear. Any payment made by a Lender pursuant to this Section 2.08(e) to reimburse any Issuer for any Letter of Credit 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 Letter of Credit Disbursement. Any Letter of Credit Disbursement not reimbursed by the Borrower or funded as a Loan prior to 2:00 p.m., New York time, shall bear interest for such day at the ABR plus the Applicable Margin.

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

33

Administrative Agent, the Lenders nor any Issuer, 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 Issuer; provided that the foregoing shall not be construed to excuse any Issuer 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 Issuer’s failure to exercise commercially reasonable care when issuing Letters of Credit and determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof or suffered by Borrower as a result of Issuer’s gross negligence or willful misconduct. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of any Issuer (as finally determined by a court of competent jurisdiction), such Issuer 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 Issuer 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 Issuer shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit issued by such Issuer. Such Issuer shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether such Issuer has made or will make a Letter of Credit 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 Issuer and the Lenders with respect to any such Letter of Credit Disbursement.

(h) Interim Interest. If any Issuer shall make any Letter of Credit Disbursement, then, until the Borrower shall have reimbursed such Issuer for such Letter of Credit 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 Letter of Credit Disbursement is made to but excluding the date that the Borrower reimburses such Letter of Credit 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 Issuer, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.08(e) to reimburse such Issuer shall be for the account of such Lender to the extent of such payment.

(i) Replacement of an Issuer. Any Issuer may be replaced or resign at any time by written agreement among the Borrower, the Administrative Agent, such resigning or replaced Issuer and, in the case of a replacement, the successor Issuer. The Administrative Agent shall notify the Lenders of any such resignation or replacement of an Issuer. At the time any such resignation or replacement shall become effective, the Borrower shall pay all unpaid fees accrued

34

for the account of the resigning or replaced Issuer pursuant to Section 3.04(b). In the case of the replacement of an Issuer, from and after the effective date of such replacement, (i) the successor Issuer shall have all the rights and obligations of the replaced Issuer under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to “Issuer” shall be deemed to refer to such successor or to any previous Issuer, or to such successor and all previous Issuers, as the context shall require. After the resignation or replacement of an Issuer hereunder, the resigning or replaced Issuer shall remain a party hereto and shall continue to have all the rights and obligations of an Issuer 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 Required Lenders demanding the deposit of cash collateral pursuant to this Section 2.08(j), or (ii) the Borrower is required to pay to the Administrative Agent the excess attributable to a Letter of Credit Exposure in connection with any prepayment pursuant to Section 3.03(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 (such account, the “Cash Collateral Account”), an amount in cash equal to, in the case of an Event of Default, the Letter of Credit Exposure, and in the case of a payment required by Section 3.03(c), the amount of such excess as provided in Section 3.03(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 Issuer and the Lenders, an exclusive first priority and continuing perfected security interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all deposits or wire transfers made thereto, any and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise payable in respect of, or in exchange for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. The Borrower’s obligation to deposit amounts pursuant to this Section 2.08(j) shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower or any of its Subsidiaries may now or hereafter have against any such beneficiary, any Issuer, 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. 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 Issuer for Letter of Credit Disbursements for which it has not

35

been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the Letter of Credit 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 a Letter of Credit Exposure in connection with any prepayment pursuant to Section 3.03(c), then such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived.

Section 2.09 Increased Commitments. So long as no Default or Event of Default has occurred and is continuing, Borrower may request that the existing Lenders be permitted to increase their Maximum Credit Amounts upon five Business Days written notice to the Administrative Agent; provided that (i) such notice shall set forth the additional amount of each Lender’s Maximum Credit Amount, (ii) the aggregate of such increases shall be in increments of $5,000,000, (iii) each increase shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage, and (iv) the Aggregate Maximum Credit Amount shall not exceed $750,000,000. As conditions precedent to the effectiveness of the increase applicable to the Lenders, the Borrower shall deliver to a Lender upon the request of any Lender, a Note in the amount of the increase in such Lender’s Maximum Credit Amount. The Administrative Agent will prepare on the last Business Day of such month a schedule of the Maximum Credit Amounts for each Lender, and will promptly provide the same to the Borrowers and each of the Lenders.

ARTICLE III

36

including any payments in respect of a Borrowing Base Deficiency under Section 3.03(c), then all Loans outstanding, in the case of an Event of Default, and such overdue amount, in the case of a failure to pay amounts when due, shall bear interest, after as well as before judgment, at the Alternate Base Rate plus two percent (2%), but in no event to exceed the Highest Lawful Rate, and (ii) following Administrative Agent’s notice of any Borrowing Base Deficiency pursuant to Section 3.03(c), the amount of such Borrowing Base Deficiency shall bear interest, after as well as before judgment, at the rate then applicable to such Loans, plus the Applicable Margin, if any, plus an additional two percent (2%), but in no event to exceed the Highest Lawful Rate.

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, and (iii) in any case, on the Termination Date; provided that (x) interest accrued pursuant to Section 3.02(c)(i) shall be payable on demand, (y) 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 (z) 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.

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 Prepayments.

(a) Optional Prepayments. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with Section 3.03(b).

(b) Notice and Terms of Optional Prepayment. The Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 1:00 pm, New York time, three Business Days before the date of prepayment, or (ii) in the case of prepayment of an ABR Borrowing, not later than 1:00 pm, New York time, one Business Day before the date of prepayment.

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.

37

(c) Mandatory Prepayments.

(i) Borrowing Base Deficiency. If a Borrowing Base Deficiency exists, then the Administrative Agent shall give the Borrower and the Lenders prompt written notice thereof. The Borrower shall, within ten (10) days after receipt of written notice of such condition from the Administrative Agent elect by written notice to the Administrative Agent to take one or more of the following actions to remedy the Borrowing Base Deficiency:

(A) prepay Advances or, if the Advances have been repaid in full, Cash Collateralize the Letter of Credit Exposure in an aggregate amount equal to such deficiency within ten (10) days after the Borrower’s written election;

(B) add additional Oil and Gas Properties acceptable to the Administrative Agent, in its sole discretion, to the Borrowing Base such that the Borrowing Base Deficiency is cured within thirty (30) days after the Borrower’s written election; or

(C) pay the Borrowing Base Deficiency in three equal monthly installments for the prepayment of the Advances or, if the Advances have been repaid in full, make deposits into the Cash Collateral Account to provide cash collateral for the Letter of Credit Exposure such that the Borrowing Base Deficiency is eliminated in a period of three months, by irrevocably dedicating a portion of the monthly cash flow from the Borrower’s and its Subsidiaries’ Oil and Gas Properties to the prepayment of Advances or, if the Advances have been repaid in full, making deposits into the Cash Collateral Account to provide cash collateral for the Letter of Credit Exposure.

(ii) Reduction of Loan Commitments. On the date of each reduction of the Aggregate Maximum Credit Amount pursuant to Section 2.06, the Borrower agrees to make a prepayment in respect of the outstanding amount of the Advances to the extent, if any, that the Total Revolving Credit Exposure exceeds the lesser of (A) the Aggregate Maximum Credit Amount, as so reduced, and (B) the Borrowing Base.

(iii) Accrued Interest. Each prepayment under this Section 3.03(c) shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 5.02 as a result of such prepayment.

(d) No Premium or Penalty. Prepayments permitted or required under this Section 3.03 shall be without premium or penalty, except as required under Section 5.02.

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 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 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 Letter of Credit Exposure (excluding any portion thereof attributable to unreimbursed Letter of Credit 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 Letter of Credit Exposure; and (ii) to each Issuer, for its own account, its standard fees with respect to the amendment, renewal or extension of any Letter of Credit issued by such Issuer 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. Any other fees payable to an Issuer pursuant to this Section 3.04(b) shall be payable within 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case such 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).

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

(d) Additional Upfront Fees. In the event that, as a result of a redetermination of the Borrowing Base, the Borrowing Base is increased to an amount that is higher than the Base Amount (such higher amount herein the “Designated Amount”), the Borrower agrees to pay to the Administrative Agent, for the account of each Lender, an upfront fee, in an amount to be agreed upon between the Borrower and the Administrative Agent, according to such Lender’s Applicable Percentage of the difference between the Designated Amount and the Base Amount; provided, however, that solely for purposes of calculating the upfront fee pursuant to this Section 3.04(d), upon payment of such upfront fee and for purposes of future upfront fees pursuant to this Section 3.04(d), the Base Amount shall be increased to be equal to the last Designated Amount for which an upfront fee has been paid hereunder.

39

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 Letter of Credit Disbursements, or of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 2:00 p.m., New York time, on the date when due (after giving effect to applicable grace periods), in immediately available funds, without defense, deduction, recoupment, set-off or counterclaim. Fees, once paid, shall be fully earned and shall not be refundable under any circumstances. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices specified in Section 12.01, except payments to be made directly to an Issuer 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, and any such payments payable to a Lender shall be made in accordance with such Lender’s Applicable Percentage, unless otherwise provided herein. 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 Letter of Credit 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 Letter of Credit Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed Letter of Credit 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 Letter of Credit Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in Letter of Credit 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 Letter of Credit 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 Letter of Credit Disbursements; provided that

40

(i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this Section 4.01(c) shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in Letter of Credit Disbursements to any assignee or participant, other than to the Borrower or any Consolidated Subsidiary 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 Issuer 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 Issuer, 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 Issuer, 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 Issuer 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) 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.

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

41

(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 Issuer 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 Issuer’s capital or on the capital of such Lender’s or such Issuer’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 Issuer, to a level below that which such Lender or such Issuer or such Lender’s or such Issuer’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such Issuer’s policies and the policies of such Lender’s or such Issuer’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or such Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuer or such Lender’s or such Issuer’s holding company for any such reduction suffered.

(c) Certificates. A certificate of a Lender or any Issuer setting forth in reasonable detail the basis of its request and the amount or amounts necessary to compensate such Lender or such Issuer 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 Issuer, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Effect of Failure or Delay in Requesting Compensation. Failure or delay on the part of any Lender or any Issuer to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s or such Issuer’s right to demand such compensation, provided that no Lender may make any such demand more than 180 days after the Termination Date, nor for any amount which has accrued more than 270 days prior to such Lender or Issuer delivering the certificate required in Section 5.01(c) unless such compensation demand results from a Change in Law that has a retroactive effect, in which case the time periods given above will be extended to take into account such retroactive period.

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

42

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

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

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Lender and each Issuer, 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 Issuer, 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 Lender or an Issuer as to the basis of such Indemnified Taxes and 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.

43

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

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

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

Section 5.06 Replacement of a Lender. If any Lender (an “Affected Lender”) (a) makes a demand upon the Borrower for amounts pursuant to Section 5.01 (and the payment of such amounts are, and are likely to continue to be, materially more onerous in the reasonable judgment of the Borrower than with respect to the other Lenders) or (b) in connection with any proposed increase in the Borrowing Base pursuant to Section 2.07 refuses to consent to such increase, the Borrower may, within 30 days of receipt by the Borrower of such demand, give notice (a “Replacement Notice”) in writing to the Administrative Agent and such Affected Lender of its intention to cause such Affected Lender to sell all of its Loans, Loan Commitments and/or Notes to an Eligible Assignee (a “Replacement Lender”) designated in such Replacement Notice; provided, however, that no Replacement Notice may be given by the Borrower and no

44

Lender may be replaced pursuant to this Section 5.06 if (i) such replacement conflicts with any applicable law or regulation, (ii) any Event of Default shall have occurred and be continuing at the time of such replacement, (iii) the Borrower has not delivered a Replacement Notice (as defined in the Alabama Credit Agreement) to the same Affected Lender (as defined in the Alabama Credit Agreement) or (iv) prior to any such replacement, such Affected Lender shall have taken any necessary action under Section 5.04 (if applicable) so as to eliminate the continued need for payment of amounts owing pursuant to Section 5.01 or shall have waived its right to payment of the specific amounts that give rise or would give rise to such Replacement Notice (it being understood for sake of clarity that the Affected Lender shall be under no obligation to waive such rights to payment and that such Affected Lender, if it is replaced in accordance with this Section 5.06, shall be entitled to be reimbursed for all breakage losses in connection with such replacement). If the Administrative Agent shall (i) in the exercise of its reasonable discretion and within 30 days of its receipt of such Replacement Notice, notify the Borrower and such Affected Lender in writing that the Replacement Lender is satisfactory to the Administrative Agent (such consent not being required where the Replacement Lender is already a Lender or an Affiliate of a Lender or an Eligible Assignee), and (ii) have received notification that the Replacement Lender is satisfactory to the Administrative Agent (as defined in the Alabama Credit Agreement) as a Replacement Lender under the Alabama Credit Agreement, then such Affected Lender shall, subject to the payment of any amounts due pursuant to Section 5.02, assign, in accordance with Section 12.04, all of its Loan Commitments, Loans, Notes (if any), and other rights and obligations under this Agreement and all other Loan Documents (including Reimbursement Obligations, if applicable) designated in the replacement notice to such Replacement Lender; provided, however, that (A) such assignment shall be without recourse, representation or warranty and shall be on terms and conditions reasonably satisfactory to such Affected Lender and such Replacement Lender, (B) the purchase price paid by such Replacement Lender shall be in the amount of such Affected Lender’s Loans designated in the Replacement Notice, and/or its Percentage of outstanding Reimbursement Obligations, as applicable, together with all accrued and unpaid interest and fees in respect thereof, plus all other amounts (including the amounts demanded and unreimbursed under Section 5.01), (C) the Borrower shall pay to the Affected Lender and the Administrative Agent all reasonable out-of-pocket expenses incurred by the Affected Lender and the Administrative Agent in connection with such assignment and assumption (including the processing fees described in Section 12.04) and (D) such assignment shall not be effective until the Affected Lender makes an assignment to the Replacement Lender pursuant to section 5.06 of the Alabama Credit Agreement and all payments and other obligations required by section 5.06 of the Alabama Credit Agreement have been fully paid and performed. If the Affected Lender fails to execute an Assignment and Assumption after five Business Days notice from the Administrative Agent, such failure to execute shall not impair the validity of the removal of the Affected Lender and the mandatory assignment of such Affected Lender’s Loan Commitments, Loans, Notes (if any), and other rights and obligations under this Agreement and all of the Loan documents and such assignment shall be effective without the execution of an Assignment and Assumption by the Affected Lender. If the Administrative Agent fails to notify Borrower within 30 days of its receipt of such Replacement Notice that such Replacement Lender is satisfactory, then such Replacement Lender shall be deemed satisfactory to the Administrative Agent. Upon the effective date of an assignment described above, the Replacement Lender shall become a “Lender” for all purposes under the Loan Documents. Without limiting the foregoing, it is intended that any Affected

45

Lender that is replaced pursuant to this Section 5.06 shall be replaced under section 5.06 of the Alabama Credit Agreement, and any Replacement Lender which replaces such Affected Lender shall replace the Affected Lender under the Alabama Credit Agreement, pursuant to the requirements of section 5.06 of the Alabama Credit Agreement.

(b) If the Borrower has provided title information for additional Properties under Section 2.07(b), the Borrower shall, within 60 days of notice from the Administrative Agent that title defects or exceptions exist with respect to such additional Properties, either (i) cure any such title defects or exceptions (including defects or exceptions as to priority) which are not permitted by Section 9.03 raised by such information, (ii) substitute acceptable Mortgaged Properties with no title defects or exceptions except for Excepted Liens (other than Excepted Liens described in clauses (v), (vi) and (viii) of such definition) 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 at least 85% of the value of the Oil and Gas Properties evaluated by such Reserve Report (excluding such Oil and Gas Properties located in the State of Alabama).

In the event that the Non-Alabama Mortgaged Properties do not represent at least 85% of such total value, then the Borrower shall, and shall cause its Subsidiaries to, grant to the Administrative Agent or its designee as security for the Obligations a first-priority Lien (provided the Excepted Liens of the type described in clauses (i) to (iv) and (vi) of the definition thereof may exist, but subject to the provisos at the end of such definition) on additional Oil and Gas Properties not already subject to a Lien of the Security Instruments and not located in the State of Alabama such that after giving effect thereto, the Non-Alabama Mortgaged Properties will represent at least 85% 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 sufficient executed (and acknowledged where necessary or appropriate) counterparts for recording purposes. In order to comply with the foregoing, if any Subsidiary places a Lien on its Oil and Gas Properties and such Subsidiary is not a Guarantor, then it shall become a Guarantor and comply with Section 8.13(b).

(b) In the event that (i) the Borrower determines that any Subsidiary is a Material Domestic Subsidiary or (ii) any Subsidiary that is a Domestic Subsidiary incurs or

67

guarantees any Debt, then the Borrower shall promptly cause such Subsidiary to guarantee the Obligations.

(v) UCC search certificates reflecting no prior Liens encumbering such Subsidiary that becomes a Guarantor pursuant to this Section 8.13(b) other than Liens permitted by Section 9.03.

Neither the Borrower nor any of its Subsidiaries will create, incur, assume or suffer to exist any contract, agreement or understanding (other than this Agreement or the Security Instruments) that in any way prohibits or restricts the granting, conveying, creation or imposition of any Lien on any of its Property in favor of the Administrative Agent and the Lenders or restricts any Subsidiary from paying dividends or making distributions to the Borrower or any Guarantor, or which requires the consent of or notice to other Persons in connection therewith.

Section 9.16 Gas Imbalances, Take-or-Pay or Other Prepayments. The Borrower will not, and will not permit any of its Subsidiaries to, allow gas imbalances, take-or-pay or other prepayments with respect to the Oil and Gas Properties of the Borrower or any of its Subsidiaries that would require the Borrower or such Subsidiary to deliver, in the aggregate, three percent (3%) or more of the monthly production of Hydrocarbons at some future time without then or thereafter receiving full payment therefor.

Section 9.17 Swap Agreements.

(a) Neither the Borrower nor any of its Subsidiaries will be a party to, or enter into, any Swap Agreements with any Person other than (i) Swap Agreements in respect of commodities (A) with an Approved Counterparty, (B) the notional volumes for which (when aggregated with other commodity Swap Agreements then in effect other than basis differential swaps on volumes already hedged pursuant to other Swap Agreements) do not exceed, as of the date such Swap Agreement is executed, the reasonably anticipated projected production from Proved Developed Producing Reserves for each month during the period during which such Swap Agreement is in effect for each of crude oil and natural gas, and (C) the notional volumes for which do not exceed the current net monthly production (regardless of projected production levels) at the time such Swap Agreement is executed, calculated separately for each of crude oil and natural gas; and (ii) Swap Agreements in respect of interest rates with an Approved Counterparty, which effectively convert interest rates from floating to fixed, the notional amounts of which (when aggregated with all other Swap Agreements of the Borrower and its Subsidiaries then in effect effectively converting interest rates from floating to fixed) do not exceed 90% of the then outstanding principal amount of the Borrower’s Debt for borrowed money which bears interest at a floating rate.

(b) The prohibitions set forth in clause (i) of Section 9.17(a) above shall not apply to Swap Agreements executed by Borrower or any of its Subsidiaries in connection with an acquisition of Oil and Gas Properties or Persons owning Oil and Gas Properties for a period of 90 days after the date of execution of such Swap Agreements; provided that, (i) such Swap Agreements are with an Approved Counterparty; and (ii) Constellation Energy Group, Inc. has guaranteed the obligations of Borrower and/or its Subsidiaries under such Swap Agreements pursuant to a written guarantee agreement in favor of Administrative Agent for the benefit of the Lenders in substantially the form of Exhibit 9.17(b) which shall (A) be sufficient to guarantee the principal amount of the obligations of Borrower and/or its Subsidiaries under such Swap Agreements, which at any time shall be the maximum aggregate amount (giving effect to any netting agreements) that Borrower and/or its Subsidiaries would be required to pay if such Swap Agreement were terminated at such time and (B) be effective until such Swap Agreements are terminated or (x) the notional volumes for Swap Agreements (when aggregated with other commodity Swap Agreements then in effect other than basis differential swaps on volumes already hedged pursuant to other Swap Agreements) do not exceed the reasonably anticipated projected production from Proved Developed Producing Reserves for each month during the period during which such Swap Agreement is in effect for each of crude oil and natural gas, and (y) the notional volumes for such Swap Agreements do not exceed the current net monthly production (regardless of projected production levels), calculated separately for each of crude oil and natural gas.

76

(c) In no event shall any Swap Agreement have any requirement, agreement or covenant for the Borrower or any of its Subsidiaries to post collateral or margin to secure their obligations under such Swap Agreement or to cover market exposures. Notwithstanding anything to the contrary in this Section 9.17, there shall be no prohibition against the Borrower entering into any “put” 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.

Section 9.18 Tax Status as Partnership; Operating Agreements. The Borrower shall not alter its status as a partnership for purposes of United States Federal Income taxes. The Borrower shall not, and shall not permit any Subsidiary to, amend or modify any provision of its articles, bylaws, or partnership or limited liability company organization or operating documents or agreements, or any agreements with Affiliates of the type referred to in Section 9.13, if such amendment or modification could reasonably be expected to have a Material Adverse Effect without the prior written consent of the Administrative Agent which consent shall not be unreasonably withheld or delayed. The Borrower agrees that any amendments or modifications to any provisions to any of the instruments referenced above dealing with the purpose or business, voting rights or management or operation shall be deemed to reasonably be expected to have a Material Adverse Effect.

Section 9.19 Management Services Agreement. If either the Borrower or its counterparty to a Management Services Agreement should elect to terminate the then effective Management Services Agreement in accordance with its terms, Borrower shall promptly give notice to the Administrative Agent, and shall within 30 days present to Administrative Agent a written detailed plan for providing management services for the Borrower’s and its Subsidiaries’ properties. The Borrower shall not implement a management services plan without the Administrative Agent’s prior written consent, which consent shall not unreasonably be withheld or delayed.

Section 9.20 Acquisition Properties. The Borrower will not, and will not permit any of its Subsidiaries to, amend, modify or supplement any of the agreements or related documents by which Borrower or any Guarantor acquires additional Mortgaged Properties if the effect thereof could reasonably be expected to have a Material Adverse Effect (and provided that the Borrower promptly furnishes to the Administrative Agent a copy of such amendment, modification or supplement).

ARTICLE XI

THE ADMINISTRATIVE AGENT AND COLLATERAL AGENT

Section 11.01 Appointment; Powers. Each of the Lenders and each Issuer hereby irrevocably appoints the Administrative Agent and the Collateral Agent as its agent and authorizes the Administrative Agent and the Collateral Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent and the Collateral 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 and Collateral Agent. The Administrative Agent and the Collateral 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 and Collateral 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 or the Collateral 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) neither the Administrative Agent nor the Collateral Agent shall have any 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 and the Collateral 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 the Collateral Agent or any of their Affiliates in any capacity. Neither the Administrative Agent nor the Collateral Agent shall be deemed to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent or the Collateral Agent by the Borrower or a Lender, and shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or under any other Loan Document or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or in any other Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, (v) the satisfaction of any condition set forth in ARTICLE 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

81

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. Neither the Administrative Agent nor the Collateral Agent shall have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent or the Collateral Agent is required to exercise in writing as directed by the Required 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 and the Collateral 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 Required Lenders or the Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) specifying the action to be taken and (b) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of taking or continuing to take any such action. The instructions as aforesaid and any action taken or failure to act pursuant thereto by the Administrative Agent or the Collateral Agent shall be binding on all of the Lenders. If a Default has occurred and is continuing, then the Administrative Agent or the Collateral Agent, as applicable, 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 or the Collateral Agent shall have received such directions, the Administrative Agent or the Collateral 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 or the Collateral Agent be required to take any action which exposes the Administrative Agent or the Collateral 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 Co-Syndication Agent 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 Required 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 neither the Administrative Agent nor the Collateral Agent shall 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 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

82

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 Issuer 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 and the Collateral 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 or the Collateral Agent, respectively. The Administrative Agent and the Collateral 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 the Collateral 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 Agent.

Section 11.06 Resignation or Removal 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 Issuer and the Borrower, and any Agent may be removed at any time with or without cause by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right, subject to the consent of the Borrower, such consent not to be unreasonably withheld or delayed, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation or removal of the retiring Agent, then the retiring Agent may, on behalf of the Lenders and each Issuer, 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. Any resignation or removal of an Agent shall result in a respective resignation or removal of such Agent as an “Agent” (as defined in the Alabama Credit Agreement) under the Alabama Credit Agreement, and any successor Agent appointed pursuant to this Section 11.06 shall be appointed as an “Agent” (as defined in the Alabama Credit Agreement) under the Alabama Credit Agreement in such respective capacity.

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 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.

83

Section 11.08 No Reliance. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent, any other Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and each other Loan Document to which it is a party. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent, any other Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document, any related agreement or any document furnished hereunder or thereunder. The Agents shall not be required to keep themselves informed as to the performance or observance by the Borrower or any of its Subsidiaries of this Agreement, the Loan Documents or any other document referred to or provided for herein or to inspect the Properties or books of the Borrower or its Subsidiaries. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder, no Agent 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 Pillsbury Winthrop Shaw Pittman LLP is acting in this transaction as special counsel to the Administrative Agent with respect to this Agreement, RBS, as administrative agent for such lenders under the Alabama Credit Agreement and to the Collateral Agent, only. Each other party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein.

Section 11.09 Administrative Agent and Collateral Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Borrower or any of its Subsidiaries, the Administrative Agent and the Collateral 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 Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the Collateral Agent, and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the Collateral Agent, and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the Collateral Agent, 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

84

authorized by each Lender to make such payments to the Administrative Agent and the Collateral Agent and, in the event that the Administrative Agent and the Collateral Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent and to the Collateral Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent, the Collateral Agent and their respective agents and counsel, and any other amounts due the Administrative Agent or the Collateral Agent under Section 12.03.

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

Section 11.10 Authority of Administrative Agent and Collateral Agent to Release Collateral and Liens. Each Lender and each Issuer hereby authorizes the Administrative Agent and the Collateral Agent to release any collateral that is permitted to be sold or released pursuant to the terms of the Loan Documents. Each Lender and each Issuer hereby authorizes the Administrative Agent and the Collateral Agent to execute and deliver to the Borrower, at the Borrower’s sole cost and expense, any and all releases of Liens, termination statements, assignments or other documents reasonably requested by the Borrower in connection with any sale or other disposition of Property to the extent such sale or other disposition is permitted by the terms of Section 9.12 or is otherwise authorized by the terms of the Loan Documents.

Section 11.11 The Arrangers and the Co-Syndication Agent. The Arrangers and the Syndication Agent shall have no duties, responsibilities or liabilities under this Agreement and the other Loan Documents other than its duties, responsibilities and liabilities in its capacity as a Lender hereunder to the extent it is a party to this Agreement as a Lender.

Section 11.12 The Alabama Credit Agreement. Each Lender acknowledges and agrees that (a) RBS is acting as administrative agent to the lenders under the Alabama Credit Agreement, as administrative agent to the Lenders under this Agreement and as Collateral Agent for the Secured Parties and (b) the terms of this Agreement and the Alabama Credit Agreement require each Lender under this Agreement to be a “Lender” under the Alabama Credit Agreement and vice versa with the same Applicable Percentage. Each Lender agrees RBS shall not be liable for any action taken by it or not taken by it under this Agreement, the Alabama Credit Agreement or any document or instrument referred to or provided for herein or therein or in connection therewith, INCLUDING ITS OWN ORDINARY NEGLIGENCE, except for it own gross negligence or willful misconduct.

(a) No failure on the part of the Administrative Agent, any other Agent, any Issuer 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 Issuer and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by Section 12.02(b), and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any other Agent, any Lender or any Issuer may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any provision hereof nor any Security Instrument securing the payment or performance of the Obligations hereunder, nor any provision thereof, may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent, or the Collateral Agent (as applicable) with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Maximum Credit Amount of any Lender without the written consent of such Lender, (ii) increase the Borrowing Base without the written consent of each Lender, decrease or maintain the Borrowing Base without the consent of the Required Lenders, or modify in any manner Section 2.07 without the consent of each Lender (except as permitted pursuant to Section 2.07(j)), (iii) reduce the principal amount of any Loan or

87

Letter of Credit Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, or reduce any other Obligations hereunder or under any other Loan Document, without the written consent of each Lender affected thereby, (iv) postpone the scheduled date of payment of the principal amount of any Loan or Letter of Credit Disbursement, or any interest thereon, or any fees payable hereunder, or any other Obligations hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Termination Date or the Maturity Date without the written consent of each Lender affected thereby, (v) change Section 4.01(b) or Section 4.01(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (vi) waive or amend Section 6.01, Section 8.13 or Section 10.02(c) 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 Guarantee Agreement), release all or substantially all of the collateral (other than as provided in Section 11.09), or reduce the percentage set forth in Section 8.13(a) to less than 85%, without the written consent of each Lender, (viii) change any of the provisions of this Section 12.02(b) or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or under any other Loan Documents or make any determination or grant any consent hereunder or any other Loan Documents, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, any other Agent, or any Issuer hereunder or under any other Loan Document without the prior written consent of the Administrative Agent, such other Agent or such Issuer, as the case may be, (ix) amend or modify the definition of Obligations to delete or exclude any obligation or liability described therein without the written consent of each Lender, (x) amend the definitions of “Swap Agreement” or “Swap Counterparty” without the consent of each Swap Counterparty, or (xi) permit the Borrower to assign or transfer any of its rights or obligations under this Agreement or other Loan Documents without the written consent of each Lender. Notwithstanding the foregoing, any supplement to Schedule 7.14 (Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental schedule clearly marked as such, and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders.

Section 12.03 Expenses; Indemnity; Damage Waiver.

Section 12.04 Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of any Issuer that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section 12.04. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of any Issuer 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 Issuer 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 to an Eligible Assignee (including all or a portion of its Loan 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 for an assignment to a Lender or an Affiliate of a Lender or, if an Event of Default has occurred and is continuing, to any other Eligible 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.

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

(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 Loan Commitment, the amount of the Loan Commitment 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;

91

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

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

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

(E) in connection with any permitted assignment of the rights and obligations of a Lender under this Agreement to any assignee, whether in whole or part, the effectiveness of such assignment shall be subject to a corresponding assignment made by such Lender to such assignee of such Lender’s rights and obligations under the Alabama Credit Agreement such that, after giving effect to such assignments, each Lender’s Applicable Percentage under this Agreement is equal to each respective Lender’s “Applicable Percentage” (as such term is define in the Alabama Credit Agreement) under the Alabama Credit Agreement.

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

(iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Maximum Credit Amount of, and principal amount of the Loans and Letter of Credit Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, each Issuer 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 Issuer and any Lender, at any reasonable time and from time to time upon reasonable prior notice. In connection

92

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 Issuer and each Lender.

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

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

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

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; 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.

93

Section 12.05 Survival; Revival; Reinstatement.

(a) All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, any other Agent, any Issuer or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Loan Commitments have not expired or terminated. The provisions of Section 5.01, Section 5.02, Section 5.03 and Section 12.03 and ARTICLE XI shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Loan Commitments or the termination of this Agreement, any other Loan Document or any provision hereof or thereof.

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

Section 12.06 Counterparts; Integration; Effectiveness.

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

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

94

(c) Except as provided in Section 6.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or electronic mail in portable document format (pdf) 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 limitations obligations under Swap Agreements) at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower or any 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. The rights of each Lender under this Section 12.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender or its Affiliates may have.

Section 12.12 Maximum Interest. It is the intention of the parties hereto to conform strictly to applicable usury laws, and, anything herein to the contrary notwithstanding, the Obligations of the Borrower to each Lender under this Agreement shall be subject to the limitation that payments of interest shall not be required to the extent that receipt thereof would be contrary to provisions of law applicable to such Lender limiting rates of interest that may be charged or collected by such Lender. Accordingly, if the transactions contemplated hereby would be usurious under applicable law (including the Federal and state laws of the United States of America, or of any other jurisdiction whose laws may be mandatorily applicable) with respect to a Lender, then, in that event, notwithstanding anything to the contrary in this Agreement, it is agreed as follows: (a) the provisions of this Section 12.12 shall govern and control; (b) the aggregate of all consideration that constitutes interest under applicable law that is contracted for, charged or received under this Agreement, or under any other Loan Document or otherwise in connection with this Agreement by such Lender shall under no circumstances exceed the Highest Lawful Rate, and any excess shall be credited to the Borrower by such Lender (or, if such consideration shall have been paid in full, such excess promptly refunded to the Borrower); (c) all sums paid, or agreed to be paid, to such Lender for the use, forbearance and detention of the indebtedness of the Borrower to such Lender hereunder shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in full so that the actual rate of interest is uniform throughout the full term thereof; and (d) if at any time the interest provided pursuant to Section 3.02, together with any other fees and expenses payable pursuant to this Agreement and the other Loan Documents and deemed interest under applicable law, exceeds that amount that would have accrued at the Highest Lawful Rate, then the amount of interest and any such fees to accrue to

97

such Lender pursuant to this Agreement shall be limited, notwithstanding anything to the contrary in this Agreement, to that amount that would have accrued at the Highest Lawful Rate, but any subsequent reductions, as applicable, shall not reduce the interest to accrue to such Lender pursuant to this Agreement below the Highest Lawful Rate until the total amount of interest accrued pursuant to this Agreement and such fees deemed to be interest equals the amount of interest that would have accrued to such Lender if a varying rate per annum equal to the interest provided pursuant to Section 3.02 had at all times been in effect, plus the amount of fees that would have been received but for the effect of this Section 12.12.

(a) the Base Rate in effect on such day; and

(b) the Federal Funds Effective Rate in effect on such day plus  ¹/2 of 1%.

Changes in the rate of interest on that portion of any Loans maintained as ABR Loans will take effect simultaneously with each change in the Alternate Base Rate. The Administrative Agent will give notice promptly to the Borrower and the Lenders of changes in the Alternate Base Rate; provided that, the failure to give such notice shall not affect the Alternate Base Rate in effect after such change.

“Applicable Margin” means, for any day and with respect to all Loans maintained as Eurodollar Loans or ABR Loans, the applicable percentage set forth below corresponding to the Borrowing Base Utilization Percentage:

If for any reason, based upon incorrect or inaccurate information provided to Administrative Agent or Lenders by Borrower, it is determined that a higher Applicable Margin should have applied to a period than was actually applied, then the proper margin shall be applied retroactively, and the Borrower shall pay to the Administrative Agent, for the benefit of the Lenders, promptly on demand therefor, an amount equal to the difference between the amount of interest and fees that would have accrued using the proper margin and the amount actually paid.

Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, repay and reborrow the Loans.

22

Section 2.02 Loans and Borrowings.

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

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

(c) Minimum Amounts; Limitation on Number of Borrowings. At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $500,000 and not less than $1,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $250,000 and not less than $1,000,000; provided that an ABR Borrowing may be in an aggregate amount that is equal to the entire unused balance of the Aggregate Maximum Credit Amount or that is required to finance the reimbursement of a Letter of Credit Disbursement as contemplated by Section 2.08(e). Borrowings of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of twelve (12) Eurodollar Borrowings outstanding. Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

(d) Notes. The Loans made by each Lender shall, if requested by such Lender in writing, be evidenced by a single promissory note of the Borrower in substantially the form of Exhibit A, dated, in the case of (i) any Lender party hereto as of the date of this Agreement, as of the date of this Agreement or (ii) any Lender that becomes a party hereto pursuant to an Assignment and Assumption, as of the effective date of the Assignment and Assumption, payable to the order of such Lender in a principal amount equal to its Maximum Credit Amount as in effect on such date, and otherwise duly completed. In the event that any Lender’s Maximum Credit Amount increases or decreases for any reason (whether pursuant to Section 2.06, Section 12.04(b) or otherwise), the Borrower shall deliver or cause to be delivered on the effective date of such increase or decrease, a new Note payable to 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 the affected Lender shall deliver the Note being replaced to the Borrower immediately. The date, amount, interest rate and 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

23

endorsed by such Lender on a schedule attached to such Note or any continuation thereof or on any separate record maintained by such Lender. Failure to make any such notation or to attach a schedule shall not affect any Lender’s or the Borrower’s rights or obligations in respect of such Loans or affect the validity of such transfer by any Lender of its Note.

Section 2.03 Requests for Borrowings. To request a Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone not later than Noon, New York time, (i) three (3) Business Days before the date of the proposed Borrowing, in the case of Eurodollar Borrowings, or (ii) on the same Business Day, in the case of ABR Borrowings. Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request in the form attached hereto as Exhibit 2.03. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02:

(i) the aggregate amount of the requested Borrowing;

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

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

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

In the case of Eurodollar Borrowings, if no Interest Period is specified with respect to any requested Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Each Borrowing Request shall constitute a representation that the amount of the requested Borrowing shall not cause the Total Revolving Credit Exposures to exceed the lesser of the Aggregate Maximum Credit Amount and the then effective Borrowing Base.

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

Section 2.04 Interest Elections.

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

24

(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. 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 in the form attached hereto as Exhibit 2.04(b) and signed by the Borrower.

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

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

(iii) the Interest Period to be applicable to such Borrowing after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

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

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

(e) Effect of Failure to Deliver Timely Interest Election Request and Events of Default and Borrowing Base Deficiencies on Interest Election. If the Borrower fails to deliver a timely Interest Election Request with respect to a 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 Loan having an Interest Period of one month. Notwithstanding any contrary provision hereof, if an Event of Default or a Borrowing Base Deficiency has occurred and is continuing, then no outstanding Borrowing may be continued (and any Interest Election Request that requests the continuation of any Borrowing shall be ineffective).

Section 2.05 Funding of Borrowing.

(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 2:00 p.m., New York time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an

25

account of the Borrower and designated by the Borrower in the applicable Borrowing Request; provided that Loans made to finance the reimbursement of a Letter of Credit Disbursement as provided in Section 2.08(e) shall be remitted by the Administrative Agent to the Issuer that made such Letter of Credit 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 Advance 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 Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

Section 2.06 Termination and Reduction of Aggregate Maximum Credit Amount.

(a) Scheduled Termination of Loan Commitments. Unless previously terminated, the Loan Commitments shall terminate on the Maturity Date. If at any time the Aggregate Maximum Credit Amount or the Borrowing Base is terminated or reduced to zero, then the Loan 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 Amount; provided that (A) each reduction of the Aggregate Maximum Credit Amount 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 Amount if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 3.03(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 Amount 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

26

notice delivered by the Borrower pursuant to this Section 2.06(b)(ii) shall be irrevocable. Any termination or reduction of the Aggregate Maximum Credit Amount shall be permanent and may not be reinstated. Each reduction of the Aggregate Maximum Credit Amount shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage.

Section 2.07 Borrowing Base.

(a) For the period from and including the Closing Date to but excluding the date of the first determination of the Borrowing Base pursuant to the further provisions of this Section 2.07, the initial amount of the Borrowing Base has been set by the Administrative Agent and acknowledged by the Borrower and agreed to by the Lenders to be $90,000,000 (the “Base Amount”). For each and every determination or redetermination of the Borrowing Base under this Agreement, the Borrowing Base shall be determined or redetermined based only on the oil and gas reserves attributable to the Oil and Gas Properties of the Borrower and its Subsidiaries located in the State of Alabama.

(b) Promptly after January 1 of each calendar year, commencing January 1, 2008, and in any event prior to March 31 of each calendar year (commencing March 31, 2008), the Borrower shall furnish to the Administrative Agent a Reserve Report in form and substance reasonably satisfactory to the Administrative Agent, prepared by an Approved Engineer, which Reserve Report shall be dated as of January 1 of such calendar year together with additional data concerning pricing, hedging, quantities and purchasers of production, and other information and engineering and geological data as the Administrative Agent may reasonably request. Within fifteen (15) days after receipt of such Reserve Report and all such information, the Administrative Agent shall make an initial determination of the new Borrowing Base (the “Proposed Borrowing Base”), which for purposes of this Section 2.07(b) is the semi-annual determination described in Section 2.07(c), and upon such initial determination shall promptly notify the Lenders in writing of its initial determination of the Proposed Borrowing Base. Such initial determinations made by the Administrative Agent shall be so made by the Administrative Agent in the exercise of its sole discretion in accordance with the Administrative Agent’s customary practices and standards for oil and gas lending as they exist at the particular time, and may include a consideration of the value of the Oil and Gas Properties that are subject to legal, valid and enforceable mortgage liens held by the Administrative Agent for the ratable benefit of the Lenders. In no event shall the Proposed Borrowing Base exceed the Aggregate Maximum Credit Amount of the Lenders. The Required Lenders shall approve or reject the Administrative Agent’s initial determinations of the Proposed Borrowing Base by written notice to the Administrative Agent within fifteen (15) days of the Administrative Agent’s notification of its initial determinations; provided, however, that failure by any Lender to confirm in writing, the Administrative Agent’s determination of the Proposed Borrowing Base shall be deemed an approval of the Proposed Borrowing Base. If the Required Lenders fail to approve any such determination of the Proposed Borrowing Base made by the Administrative Agent hereunder in such fifteen (15) day period, then the Administrative Agent shall poll the Lenders to ascertain the highest Proposed Borrowing Base then acceptable to the Required Lenders for purposes of this Section 2.07(b) and, subject to the last sentence of this Section 2.07(b), such amounts shall become the new Borrowing Base, effective on the date specified in this Section 2.07. Until such approval or deemed approval, the Borrowing Base in effect before the Proposed Borrowing Base

27

shall remain in effect. Upon agreement by the Administrative Agent and the Required Lenders of the new Borrowing Base, the Administrative Agent shall, by written notice to the Borrower and the Lenders, designate the new Borrowing Base available to the Borrower. Such designation shall be effective as of the Business Day specified in such written notice (or, if no effective date is specified in such written notice, the next Business Day following delivery of such written notice), and such new Borrowing Base shall remain in effect until the next determination or redetermination of the Borrowing Base in accordance with this Agreement. Anything herein contained to the contrary notwithstanding, any determination or redetermination of the Borrowing Base resulting in any increase of the Borrowing Base in effect immediately prior to such determination or redetermination shall require the approval of all the Lenders in their sole discretion in accordance with their respective customary practices and standards for oil and gas lending as they exist at the particular time, and may include a consideration of the value of the Oil and Gas Properties that are subject to legal, valid and enforceable mortgage liens held by the Administrative Agent for the ratable benefit of the Lenders.

(c) In addition, within ninety (90) days after each June 30, commencing June 30, 2008, the Borrower shall furnish to the Administrative Agent a Reserve Report in form and substance satisfactory to the Administrative Agent, prepared by the Borrower’s petroleum engineers or on behalf of Borrower by petroleum engineers under the Management Services Agreement, which report shall be dated as of July 1 of such calendar year together with additional data concerning pricing, hedging, quantities and purchasers of production, and other information and engineering and geological data as the Administrative Agent may reasonably request. Within fifteen (15) days after receipt of such Reserve Report and all such information, the Administrative Agent shall make an initial determination of a Proposed Borrowing Base, and upon such initial determination shall promptly notify the Lenders in writing of initial determination of the Proposed Borrowing Base. Such initial determination shall be made in the same manner and be subject to the same approvals as prescribed above with respect to the annual review, and likewise the Administrative Agent shall communicate the results of such initial determinations to the Lenders. The Required Lenders shall approve such determinations of the Proposed Borrowing Base by written notice to the Administrative Agent within fifteen (15) days of the giving of notice of such determinations by the Administrative Agent to such Lenders; provided, however, that failure by any Lender to confirm in writing the Administrative Agent’s determination of the Proposed Borrowing Base shall be deemed an approval of the Proposed Borrowing Base. If the Required Lenders fail to approve any such determination of the Proposed Borrowing Base made by the Administrative Agent hereunder in such fifteen (15) day period, then the Administrative Agent shall poll the Lenders to ascertain the highest Proposed Borrowing Base then acceptable to the Required Lenders for purposes of this Section 2.07(c) and, subject to the last sentence of this Section 2.07(c), such amounts shall become the new Borrowing Base, effective on the date specified in this Section 2.07. Upon agreement by the Administrative Agent and the Required Lenders of the amount of credit to be made available to the Borrower hereunder, the Administrative Agent shall, by written notice to the Borrower and the Lenders, designate the new Borrowing Base available to the Borrower. Such designation shall be effective as of the Business Day specified in such written notice (or, if no effective date is specified in such written notice, the next Business Day following delivery of such written notice) and such new Borrowing Base shall remain in effect until the next determination or redetermination of the Borrowing Base in accordance with this Agreement. Anything herein

28

contained to the contrary notwithstanding, any determination or redetermination of the Borrowing Base resulting in any increase of the Borrowing Base in effect immediately prior to such determination or redetermination shall require the approval of all the Lenders in their sole discretion in accordance with their respective customary practices and standards for oil and gas lending as they exist at the particular time, and may include a consideration of the value of the Oil and Gas Properties that are subject to legal, valid and enforceable mortgage liens held by the Administrative Agent for the ratable benefit of the Lenders.

(d) In addition to the foregoing scheduled annual and semi annual determinations of the Borrowing Base, the Required Lenders shall have the right to redetermine the Borrowing Base at their sole discretion at any time and from time to time but not more often than two (2) times every calendar year. If the Required Lenders shall elect to make a discretionary redetermination of the Borrowing Base pursuant to the provisions of this Section 2.07(d), the Borrower shall within thirty (30) days of receipt of a request therefor from the Administrative Agent, deliver to the Administrative Agent a Reserve Report in form and substance satisfactory to the Administrative Agent, prepared by the Borrower’s petroleum engineers containing information similar to the Reserve Reports delivered pursuant to Section 2.07(c), together with such updated engineering, production, operating and other data as the Administrative Agent, the Issuer or any Lender may reasonably request. The Administrative Agent shall have fifteen (15) days following receipt of such requested information to make an initial redetermination of the Borrowing Base, and the Administrative Agent and the Required Lenders shall approve and designate the new Borrowing Base in accordance with the procedures and standards described in Section 2.07(b).

(e) In addition to the foregoing determinations of the Borrowing Base, the Borrower may request a redetermination of the Borrowing Base at any time and from time to time but not more often than two (2) times every calendar year, by delivering a written request to the Administrative Agent, together with (a) an engineering fee in the aggregate amount of $2,500 for the account of the Administrative Agent in immediately available funds, and (b) a Reserve Report in form and substance satisfactory to the Administrative Agent, prepared by the Borrower’s petroleum engineers containing information similar to the Reserve Reports delivered pursuant to Section 2.07(c), together with such other updated engineering, production, operating and other data as the Administrative Agent, the Issuer or any Lender may reasonably request. Each such discretionary redetermination of the Borrowing Base shall be made in the same manner and in accordance with the procedures and standards set forth above by adjusting the Borrowing Base then in effect. The Administrative Agent shall have fifteen (15) days following receipt of such requested information to make an initial redetermination of the Borrowing Base, and the Administrative Agent and the Required Lenders shall approve and designate the new Borrowing Base in accordance with the procedures and standards described in Section 2.07(b).

(f) In addition to the Borrower’s right to request a discretionary Borrowing Base redetermination as set forth in Section 2.07(e), the Borrower may request a redetermination of the Borrowing Base at any time and from time to time upon the acquisition by the Borrower of (i) additional Oil and Gas Properties or (ii) a Person that owns Oil and Gas Properties, the purchase price of which shall represent at least 20% of the Borrowing Base then in effect, by delivering a written request to the Administrative Agent, together with (a) an engineering fee in the aggregate amount of $2,500 for the account of the Administrative Agent in immediately

29

available funds, (b) a Reserve Report in form and substance satisfactory to the Administrative Agent with respect to Oil and Gas Properties represented in the existing Borrowing Base, prepared and delivered in accordance with Section 2.07(c), (c) a Reserve Report in form and substance satisfactory to the Administrative Agent, with respect to Oil and Gas Properties acquired since the most recent redetermination of the Borrowing Base, prepared and delivered in accordance with Section 2.07(b), and (d) a most recent draft of the agreements by which the Borrower proposes to acquire such additional Oil and Gas Properties or such Person that owns such Oil and Gas Properties, which drafts shall be supplemented upon execution by true and complete executed copies of the same. Each such redetermination of the Borrowing Base under this Section 2.07(f) shall be made in the same manner and in accordance with the procedures and standards set forth above by adjusting the Borrowing Base then in effect. The Administrative Agent shall have fifteen (15) days following receipt of such requested information to make an initial redetermination of the Borrowing Base, and the Administrative Agent and the Required Lenders shall approve and designate the new Borrowing Base in accordance with the procedures and standards described in Section 2.07(b).

(g) Notwithstanding anything to the contrary contained herein, upon the consummation of a Material Swap Transaction, the Required Lenders shall have the right to redetermine the Borrowing Base using information available to them, and the redetermined Borrowing Base shall become the new Borrowing Base immediately upon notice by the Administrative Agent to the Borrower, effective and applicable to the Borrower, the Administrative Agent, and each Lender on such date until the next redetermination or modification thereof hereunder (subject to the reduction described in Section 2.07(i)). The Borrowing Base will also be redetermined or adjusted in accordance with the provisions of Section 8.12(c) or Section 9.12(d).

(h) With the delivery of each Reserve Report, the Borrower shall provide to the Administrative Agent a certificate from a Responsible Officer certifying that, to the best of such Responsible Officer’s knowledge and in all material respects: (i) the information contained in each such Reserve Report and any other information delivered in connection therewith is true and correct, (ii) the Borrower or the Guarantors owns good and defensible title to the Oil and Gas Properties evaluated in each such Reserve Report and such Properties are free of all Liens except for Liens permitted by Section 9.03, (iii) except as set forth on an exhibit to the certificate, on a net basis there are no gas imbalances, take or pay or other prepayments in excess of the volume specified in Section 7.20 with respect to their Oil and Gas Properties evaluated in such Reserve Report that would require the Borrower or any of its Subsidiaries to deliver Hydrocarbons either generally or produced from such Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor, (iv) none of their Oil and Gas Properties have been sold since the date of the last Borrowing Base determination except as set forth on an exhibit to the certificate, which certificate shall list all of its Oil and Gas Properties sold and in such detail as reasonably required by the Administrative Agent, (v) attached to the certificate is a list of all marketing agreements entered into subsequent to the later of the date hereof or the most recently delivered Reserve Report that the Borrower could reasonably be expected to have been obligated to list on Schedule 7.20 had such agreement been in effect on the date hereof, (vi) attached thereto is a schedule of the Oil and Gas Properties evaluated by such Reserve Report that are Mortgaged Properties and demonstrating the percentage of the present value that such Mortgaged

30

Properties represent, (vii) the outstanding amount of the Debt of the Borrower or any of its Subsidiaries permitted to be incurred pursuant to Section 9.02(e), and (viii) the amount of the Non-Alabama Total Revolving Credit Exposure.

(i) Notwithstanding anything herein the contrary, in the event that the Borrower does not furnish any required Reserve Report within ten (10) days of date the required herein, the Administrative Agent and the Required Lenders may nonetheless designate the Borrowing Base from time to time thereafter until the Administrative Agent receives such Reserve Report, whereupon the Administrative Agent and the Required Lenders or all Lenders, as applicable, shall designate a new Borrowing Base in accordance with the general procedures outlined in Section 2.07(b).

(j) Notwithstanding the requirements of Section 12.02(b)(ii), any decrease of the Borrowing Base resulting solely as a result of any incurrence of Debt incurred by Borrower or any of its Subsidiaries shall become effective upon the Administrative Agent’s notice thereof to the Borrower and the Lenders, and shall not require any approval of the Lenders or the Required Lenders.

Section 2.08 Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request any Issuer to issue Letters of Credit for its own account or for the account of any of its Subsidiaries, in a form reasonably acceptable to the Administrative Agent and such Issuer, 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 Letter of Credit Agreement submitted by the Borrower to, or entered into by the Borrower with, an Issuer 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 Issuer) to any Issuer and the Administrative Agent (not less than five (5) Business Days in advance of the requested date of issuance, amendment, renewal or extension) a notice in the form of Exhibit 2.08(b):

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

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

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

31

(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 Letter of Credit Exposure shall not exceed the Letter of Credit Commitment and (ii) the Total Revolving Credit Exposures shall not exceed the lesser of the Aggregate Maximum Credit Amount and the then effective Borrowing Base.

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

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is five Business Days prior to the Maturity Date.

(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 Issuer that issues such Letter of Credit or the Lenders, each Issuer that issues a Letter of Credit hereunder hereby grants to each Lender, and each Lender hereby acquires from such Issuer, 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 Issuer that issues a Letter of Credit hereunder, such Lender’s Applicable Percentage of each Letter of Credit Disbursement made by such Issuer and not reimbursed by the Borrower on the date due as provided in Section 2.08(e), or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this Section 2.08(d) in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default, the existence of a Borrowing Base Deficiency or reduction or termination of the Loan Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If any Issuer shall make any Letter of Credit Disbursement in respect of a Letter of Credit issued by such Issuer, the Borrower shall reimburse such Letter of

32

Credit Disbursement by paying to the Administrative Agent for the account of the applicable Issuer at the Alternate Base Rate plus the Applicable Margin, an amount equal to such Letter of Credit Disbursement not later than 12:00 p.m., New York time, on the day such Letter of Credit Disbursement is made, if the Borrower shall have received notice of such Letter of Credit Disbursement prior to 10:00 a.m., New York 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 2:00 p.m., New York time, on the next succeeding Business Day; provided that if such Letter of Credit Disbursement is not less than $1,000,000, the Borrower shall, subject to the conditions to Borrowing set forth herein, be deemed to have requested, and the Borrower does hereby request under such circumstances, that such payment be financed with an ABR Loan in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Loan. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable Letter of Credit 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 Issuer 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 Issuer 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 Issuer, then to such Lenders and such Issuer as their interests may appear. Any payment made by a Lender pursuant to this Section 2.08(e) to reimburse any Issuer for any Letter of Credit 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 Letter of Credit Disbursement. Any Letter of Credit Disbursement not reimbursed by the Borrower or funded as a Loan prior to 2:00 p.m., New York time, shall bear interest for such day at the ABR plus the Applicable Margin.

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

33

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 Issuer; provided that the foregoing shall not be construed to excuse any Issuer 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 Issuer’s failure to exercise commercially reasonable care when issuing Letters of Credit and determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof or suffered by Borrower as a result of Issuer’s gross negligence or willful misconduct. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of any Issuer (as finally determined by a court of competent jurisdiction), such Issuer 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 Issuer 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 Issuer shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit issued by such Issuer. Such Issuer shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether such Issuer has made or will make a Letter of Credit 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 Issuer and the Lenders with respect to any such Letter of Credit Disbursement.

(h) Interim Interest. If any Issuer shall make any Letter of Credit Disbursement, then, until the Borrower shall have reimbursed such Issuer for such Letter of Credit 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 Letter of Credit Disbursement is made to but excluding the date that the Borrower reimburses such Letter of Credit 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 Issuer, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.08(e) to reimburse such Issuer shall be for the account of such Lender to the extent of such payment.

(i) Replacement of an Issuer. Any Issuer may be replaced or resign at any time by written agreement among the Borrower, the Administrative Agent, such resigning or replaced Issuer and, in the case of a replacement, the successor Issuer. The Administrative Agent shall notify the Lenders of any such resignation or replacement of an Issuer. 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 Issuer pursuant to Section 3.04(b). In the case of the replacement of an Issuer, from and after the effective date of such replacement, (i) the successor

34

Issuer shall have all the rights and obligations of the replaced Issuer under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to “Issuer” shall be deemed to refer to such successor or to any previous Issuer, or to such successor and all previous Issuers, as the context shall require. After the resignation or replacement of an Issuer hereunder, the resigning or replaced Issuer shall remain a party hereto and shall continue to have all the rights and obligations of an Issuer 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 Required Lenders demanding the deposit of cash collateral pursuant to this Section 2.08(j), or (ii) the Borrower is required to pay to the Administrative Agent the excess attributable to a Letter of Credit Exposure in connection with any prepayment pursuant to Section 3.03(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 (such account, the “Cash Collateral Account”), an amount in cash equal to, in the case of an Event of Default, the Letter of Credit Exposure, and in the case of a payment required by Section 3.03(c), the amount of such excess as provided in Section 3.03(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 Issuer and the Lenders, an exclusive first priority and continuing perfected security interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all deposits or wire transfers made thereto, any and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise payable in respect of, or in exchange for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. The Borrower’s obligation to deposit amounts pursuant to this Section 2.08(j) shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower or any of its Subsidiaries may now or hereafter have against any such beneficiary, any Issuer, 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. 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 Issuer for Letter of Credit 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 Letter of Credit Exposure at such time or, if

35

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 a Letter of Credit Exposure in connection with any prepayment pursuant to Section 3.03(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

(C) pay the Borrowing Base Deficiency in three equal monthly installments for the prepayment of the Advances or, if the Advances have been repaid in full, make deposits into the Cash Collateral Account to provide cash collateral for the Letter of Credit Exposure such that the Borrowing Base Deficiency is eliminated in a period of three months, by irrevocably dedicating a portion of the monthly cash flow from the Borrower’s and its Subsidiaries’ Oil and Gas Properties to the prepayment of Advances or, if the Advances have been repaid in full, making deposits into the Cash Collateral Account to provide cash collateral for the Letter of Credit Exposure.

(ii) Reduction of Loan Commitments. On the date of each reduction of the Aggregate Maximum Credit Amount pursuant to Section 2.06, the Borrower agrees to make a prepayment in respect of the outstanding amount of the Advances to the extent, if any, that the Total Revolving Credit Exposure exceeds the lesser of (A) the Aggregate Maximum Credit Amount, as so reduced, and (B) the Borrowing Base.

(iii) Accrued Interest. Each prepayment under this Section 3.03(c) shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 5.02 as a result of such prepayment.

(b) Letter of Credit Fees. The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Margin used to determine the

38

interest rate applicable to Eurodollar Loans on the average daily amount of such Lender’s Letter of Credit Exposure (excluding any portion thereof attributable to unreimbursed Letter of Credit 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 Letter of Credit Exposure; and (ii) to each Issuer, for its own account, its standard fees with respect to the amendment, renewal or extension of any Letter of Credit issued by such Issuer 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. Any other fees payable to an Issuer pursuant to this Section 3.04(b) shall be payable within 10 days after demand.

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

(d) Additional Upfront Fees. In the event that, as a result of a redetermination of the Borrowing Base, the Borrowing Base is increased to an amount that is higher than Base Amount (such higher amount herein the “Designated Amount”), the Borrower agrees to pay to the Administrative Agent, for the account of each Lender, an upfront fee, in an amount to be agreed upon between the Borrower and the Administrative Agent, according to such Lender’s Applicable Percentage of the difference between the Designated Amount and the Base Amount; provided, however, that solely for purposes of calculating the upfront fee pursuant to this Section 3.04(d), upon payment of such upfront fee and for purposes of future upfront fees pursuant to this Section 3.04(d), the Base Amount shall be increased to be equal to the last Designated Amount for which an upfront fee has been paid hereunder.

be made to the Administrative Agent at its offices specified in Section 12.01, except payments to be made directly to an Issuer 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, and any such payments payable to a Lender shall be made in accordance with such Lender’s Applicable Percentage, unless otherwise provided herein. 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 Letter of Credit 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 Letter of Credit Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed Letter of Credit 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 Letter of Credit Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in Letter of Credit 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 Letter of Credit 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 Letter of Credit 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, 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 Letter of Credit Disbursements to any assignee or participant, other than to the Borrower or any Consolidated Subsidiary 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

40

due to the Administrative Agent for the account of the Lenders or any Issuer 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 Issuer, 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 Issuer, 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 Issuer 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) 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.

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

(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 Issuer 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 Issuer’s capital or on the capital of such Lender’s or such Issuer’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

41

Issuer, to a level below that which such Lender or such Issuer or such Lender’s or such Issuer’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such Issuer’s policies and the policies of such Lender’s or such Issuer’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or such Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuer or such Lender’s or such Issuer’s holding company for any such reduction suffered.

(c) Certificates. A certificate of a Lender or any Issuer setting forth in reasonable detail the basis of its request and the amount or amounts necessary to compensate such Lender or such Issuer 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 Issuer, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Effect of Failure or Delay in Requesting Compensation. Failure or delay on the part of any Lender or any Issuer to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s or such Issuer’s right to demand such compensation, provided that no Lender may make any such demand more than 180 days after the Termination Date, nor for any amount which has accrued more than 270 days prior to such Lender or Issuer delivering the certificate required in Section 5.01(c) unless such compensation demand results from a Change in Law that has a retroactive effect, in which case the time periods given above will be extended to take into account such retroactive period.

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

42

Section 5.03 Taxes.

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

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

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

Section 5.04 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

43

funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (a) would eliminate or reduce amounts payable pursuant to Section 5.01 or Section 5.03, as the case may be, in the future and (b) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

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

Section 5.06 Replacement of a Lender. If any Lender (an “Affected Lender”) (a) makes a demand upon the Borrower for amounts pursuant to Section 5.01 (and the payment of such amounts are, and are likely to continue to be, materially more onerous in the reasonable judgment of the Borrower than with respect to the other Lenders) or (b) in connection with any proposed increase in the Borrowing Base pursuant to Section 2.07 refuses to consent to such increase, the Borrower may, within 30 days of receipt by the Borrower of such demand, give notice (a “Replacement Notice”) in writing to the Administrative Agent and such Affected Lender of its intention to cause such Affected Lender to sell all of its Loans, Loan Commitments and/or Notes to an Eligible Assignee (a “Replacement Lender”) designated in such Replacement Notice; provided, however, that no Replacement Notice may be given by the Borrower and no Lender may be replaced pursuant to this Section 5.06 if (i) such replacement conflicts with any applicable law or regulation, (ii) any Event of Default shall have occurred and be continuing at the time of such replacement, (iii) the Borrower has not delivered a Replacement Notice (as defined in the Non-Alabama Credit Agreement) to the same Affected Lender (as defined in the Non-Alabama Credit Agreement) or (iv) prior to any such replacement, such Affected Lender shall have taken any necessary action under Section 5.04 (if applicable) so as to eliminate the continued need for payment of amounts owing pursuant to Section 5.01 or shall have waived its right to payment of the specific amounts that give rise or would give rise to such Replacement Notice (it being understood for sake of clarity that the Affected Lender shall be under no obligation to waive such rights to payment and that such Affected Lender, if it is replaced in accordance with this Section 5.06, shall be entitled to be reimbursed for all breakage losses in connection with such replacement). If the Administrative Agent shall (i) in the exercise of its reasonable discretion and within 30 days of its receipt of such Replacement Notice, notify the Borrower and such Affected Lender in writing that the Replacement Lender is satisfactory to the

44

Administrative Agent (such consent not being required where the Replacement Lender is already a Lender or an Affiliate of a Lender or an Eligible Assignee), and (ii) have received notification that the Replacement Lender is satisfactory to the Administrative Agent (as defined in the Non-Alabama Credit Agreement) as a Replacement Lender under the Non-Alabama Credit Agreement, then such Affected Lender shall, subject to the payment of any amounts due pursuant to Section 5.02, assign, in accordance with Section 12.04, all of its Loan Commitments, Loans, Notes (if any), and other rights and obligations under this Agreement and all other Loan Documents (including Reimbursement Obligations, if applicable) designated in the replacement notice to such Replacement Lender; provided, however, that (A) such assignment shall be without recourse, representation or warranty and shall be on terms and conditions reasonably satisfactory to such Affected Lender and such Replacement Lender, (B) the purchase price paid by such Replacement Lender shall be in the amount of such Affected Lender’s Loans designated in the Replacement Notice, and/or its Percentage of outstanding Reimbursement Obligations, as applicable, together with all accrued and unpaid interest and fees in respect thereof, plus all other amounts (including the amounts demanded and unreimbursed under Section 5.01), (C) the Borrower shall pay to the Affected Lender and the Administrative Agent all reasonable out-of-pocket expenses incurred by the Affected Lender and the Administrative Agent in connection with such assignment and assumption (including the processing fees described in Section 12.04) and (D) such assignment shall not be effective until the Affected Lender makes an assignment to the Replacement Lender pursuant to section 5.06 of the Non-Alabama Credit Agreement and all payments and other obligations required by section 5.06 of the Non-Alabama Credit Agreement have been fully paid and performed. If the Affected Lender fails to execute an Assignment and Assumption after five Business Days notice from the Administrative Agent, such failure to execute shall not impair the validity of the removal of the Affected Lender and the mandatory assignment of such Affected Lender’s Loan Commitments, Loans, Notes (if any), and other rights and obligations under this Agreement and all of the Loan documents and such assignment shall be effective without the execution of an Assignment and Assumption by the Affected Lender. If the Administrative Agent fails to notify Borrower within 30 days of its receipt of such Replacement Notice that such Replacement Lender is satisfactory, then such Replacement Lender shall be deemed satisfactory to the Administrative Agent. Upon the effective date of an assignment described above, the Replacement Lender shall become a “Lender” for all purposes under the Loan Documents. Without limiting the foregoing, it is intended that any Affected Lender that is replaced pursuant to this Section 5.06 shall be replaced under section 5.06 of the Non-Alabama Credit Agreement, and any Replacement Lender which replaces such Affected Lender shall replace the Affected Lender under the Non-Alabama Credit Agreement, pursuant to the requirements of section 5.06 of the Non-Alabama Credit Agreement.

The Transactions are within the Borrower’s and each Guarantor’s limited liability company powers and have been duly authorized by all necessary limited liability company and, if required, member action (including, without limitation, any action required to be taken by any class of directors of the Borrower or any other Person, whether interested or disinterested, in order to ensure the due authorization of the Transactions). When executed and delivered, each Loan Document and each of the agreements by which Borrower or any Guarantor acquires ownership of the Mortgaged Properties to which the Borrower and any Guarantor is a party will have been duly executed and delivered by the Borrower and such Guarantor and will constitute a legal, valid and binding obligation of the Borrower and such Guarantor, as applicable, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

The Transactions (a) do not require any consent, license, or approval of, registration or filing with, or any other action by, any Governmental Authority or any other third Person (including the members or any class of directors of the Borrower or any other Person, whether interested or disinterested), except such as have been obtained or made and are in full force and effect, and except for the filing and recording of Security Instruments to perfect the Liens created by such Security Instruments, (b) will not violate any applicable law or regulation or the charter, by-laws, operating agreement or other organizational documents of the Borrower or any of the Guarantors or any order of any

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

50

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

Section 8.12 Title Information.

(a) On or before the delivery to the Administrative Agent and the Lenders of each Reserve Report required by Section 2.07(b), to the extent requested by the Administrative Agent, the Borrower will deliver title information in form and substance acceptable to the Administrative Agent covering enough of the Oil and Gas Properties evaluated by such Reserve Report that were not included in the immediately preceding Reserve Report, so that the Administrative Agent shall have received together with title information previously delivered to the Administrative Agent, satisfactory title information on at least 85% of the total value of the Oil and Gas Properties located in the State of Alabama evaluated by such Reserve Report.

(b) If the Borrower has provided title information for additional Properties under Section 2.07(b), the Borrower shall, within 60 days of notice from the Administrative Agent that title defects or exceptions exist with respect to such additional Properties, either (i) cure any such title defects or exceptions (including defects or exceptions as to priority) which are not permitted by Section 9.03 raised by such information, (ii) substitute acceptable Mortgaged Properties with no title defects or exceptions except for Excepted Liens (other than Excepted Liens described in clauses (v), (vi) and (viii) of such definition) 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 at least 85% of the value of the Oil and Gas Properties located in the State of Alabama evaluated by such Reserve Report.

(c) If the Borrower is unable to cure any title defect requested by the Administrative Agent or the Lenders to be cured within the 60-day period or the Borrower does not comply with the requirements to provide acceptable title information covering 85% of the value of the Oil and Gas Properties located in the State of Alabama evaluated in the most recent Reserve Report, such default shall not be a Default, but instead the Administrative Agent and/or the Required Lenders shall have the right to exercise the following remedy in their sole discretion from time to time, and any failure to so exercise this remedy at any time shall not be a waiver as to future exercise of the remedy by the Administrative Agent or the Lenders. To the extent that the Administrative Agent or the Required Lenders are not reasonably satisfied with title to any Oil and Gas Properties after the 60-day period has elapsed, such unacceptable Oil and Gas Properties shall not count towards the 85% requirement in this Section 8.12(c), and the Administrative Agent may send a notice to the Borrower and the Lenders that the then outstanding Borrowing Base shall be reduced by an amount as determined by the Required Lenders to cause the Borrower to be in compliance with the requirement to provide acceptable

66

title information on 85% of the value of the Oil and Gas Properties located in the State of Alabama. This new Borrowing Base shall become effective immediately after receipt of such notice.

In the event that the Alabama Mortgaged Properties do not represent at least 85% of such total value, then the Borrower shall, and shall cause its Subsidiaries to, grant to the Administrative Agent or its designee as security for the Obligations a first-priority Lien (provided the Excepted Liens of the type described in clauses (i) to (iv) and (vi) of the definition thereof may exist, but subject to the provisos at the end of such definition) on additional Oil and Gas Properties not already subject to a Lien of the Security Instruments and located in the State of Alabama such that after giving effect thereto, the Alabama Mortgaged Properties will represent at least 85% 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 sufficient executed (and acknowledged where necessary or appropriate) counterparts for recording purposes. In order to comply with the foregoing, if any Subsidiary places a Lien on its Oil and Gas Properties and such Subsidiary is not a Guarantor, then it shall become a Guarantor and comply with Section 8.13(b).

(b) In the event that (i) the Borrower determines that any Subsidiary is a Material Domestic Subsidiary or (ii) any Subsidiary that is a Domestic Subsidiary incurs or guarantees any Debt, then the Borrower shall promptly cause such Subsidiary to guarantee the Obligations. In connection with any such guaranty, the Borrower shall, or shall cause such Subsidiary to, (A) execute and deliver a supplement to the Guarantee Agreement in the form of Annex 1 to the Guarantee Agreement executed by such Subsidiary, (B) pledge all of the Equity Interests of such Subsidiary (including, without limitation, delivery of original stock or membership interest certificates (if such interests are certificated) evidencing all of the issued and outstanding Equity Interests of such Subsidiary to Collateral Agent, together with appropriate undated stock powers, or other equivalent instruments of transfer reasonably acceptable to Administrative Agent, for each certificate duly executed in blank by the registered owner thereof) and (C) execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent or its designee, including without limitation:

75

and natural gas; and (ii) Swap Agreements in respect of interest rates with an Approved Counterparty, which effectively convert interest rates from floating to fixed, the notional amounts of which (when aggregated with all other Swap Agreements of the Borrower and its Subsidiaries then in effect effectively converting interest rates from floating to fixed) do not exceed 90% of the then outstanding principal amount of the Borrower’s Debt for borrowed money which bears interest at a floating rate.

(b) The prohibitions set forth in clause (i) of Section 9.17(a) above shall not apply to Swap Agreements executed by Borrower or any of its Subsidiaries in connection with an acquisition of Oil and Gas Properties or Persons owning Oil and Gas Properties for a period of 90 days after the date of execution of such Swap Agreements; provided that, (i) such Swap Agreements are with an Approved Counterparty; and (ii) Constellation Energy Group, Inc. has guaranteed the obligations of Borrower and/or its Subsidiaries under such Swap Agreements pursuant to a written guarantee agreement in favor of Administrative Agent for the benefit of the Lenders in substantially the form of Exhibit 9.17(b) which shall (A) be sufficient to guarantee the principal amount of the obligations of Borrower and/or its Subsidiaries under such Swap Agreements, which at any time shall be the maximum aggregate amount (giving effect to any netting agreements) that Borrower and/or its Subsidiaries would be required to pay if such Swap Agreement were terminated at such time and (B) be effective until such Swap Agreements are terminated or (x) the notional volumes for Swap Agreements (when aggregated with other commodity Swap Agreements then in effect other than basis differential swaps on volumes already hedged pursuant to other Swap Agreements) do not exceed the reasonably anticipated projected production from Proved Developed Producing Reserves for each month during the period during which such Swap Agreement is in effect for each of crude oil and natural gas, and (y) the notional volumes for such Swap Agreements do not exceed the current net monthly production (regardless of projected production levels), calculated separately for each of crude oil and natural gas.

(c) In no event shall any Swap Agreement have any requirement, agreement or covenant for the Borrower or any of its Subsidiaries to post collateral or margin to secure their obligations under such Swap Agreement or to cover market exposures. Notwithstanding anything to the contrary in this Section 9.17, there shall be no prohibition against the Borrower entering into any “put” 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.

Section 9.20 Acquisition Properties. The Borrower will not, and will not permit any of its Subsidiaries to, amend, modify or supplement any of the agreements or related documents by which Borrower or any Guarantor acquires additional Mortgaged Properties if the effect thereof could reasonably be expected to have a Material Adverse Effect (and provided that the Borrower promptly furnishes to the Administrative Agent a copy of such amendment, modification or supplement).

ARTICLE XI

THE ADMINISTRATIVE AGENT AND COLLATERAL AGENT

Section 11.01 Appointment; Powers. Each of the Lenders and each Issuer hereby irrevocably appoints the Administrative Agent and the Collateral Agent as its agent and authorizes the Administrative Agent and the Collateral Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent and the Collateral 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 and Collateral Agent. The Administrative Agent and the Collateral 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 and Collateral 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 or the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law; rather, such

80

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) neither the Administrative Agent nor the Collateral Agent shall have any 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 and the Collateral 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 the Collateral Agent or any of their Affiliates in any capacity. Neither the Administrative Agent nor the Collateral Agent shall be deemed to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent or the Collateral Agent by the Borrower or a Lender, and shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or under any other Loan Document or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or in any other Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, (v) the satisfaction of any condition set forth in ARTICLE 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. Neither the Administrative Agent nor the Collateral Agent shall have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent or the Collateral Agent is required to exercise in writing as directed by the Required 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 and the Collateral 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 Required Lenders or the Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) specifying the action to be taken and (b) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of taking or continuing to take any such action. The instructions as aforesaid and any action taken or failure to act pursuant thereto by the Administrative Agent or the Collateral Agent shall be binding on all of the Lenders. If a Default has occurred and is continuing, then the Administrative Agent or the

81

Collateral Agent, as applicable, 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 or the Collateral Agent shall have received such directions, the Administrative Agent or the Collateral 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 or the Collateral Agent be required to take any action which exposes the Administrative Agent or the Collateral 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 Co-Syndication Agent 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 Required 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 neither the Administrative Agent nor the Collateral Agent shall 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 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 Issuer 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 and the Collateral 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 or the Collateral Agent, respectively. The Administrative Agent and the Collateral 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 the Collateral 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 Agent.

Section 11.06 Resignation or Removal 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 Issuer and the Borrower, and any Agent may be removed at any time with or without cause by the Required Lenders. Upon any such resignation or removal,

82

the Required Lenders shall have the right, subject to the consent of the Borrower, such consent not to be unreasonably withheld or delayed, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation or removal of the retiring Agent, then the retiring Agent may, on behalf of the Lenders and each Issuer, 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. Any resignation or removal of an Agent shall result in a respective resignation or removal of such Agent as an “Agent” (as defined in the Non-Alabama Credit Agreement) under the Non-Alabama Credit Agreement, and any successor Agent appointed pursuant to this Section 11.06 shall be appointed as an “Agent” (as defined in the Non-Alabama Credit Agreement) under the Non-Alabama Credit Agreement in such respective capacity.

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

Section 11.08 No Reliance. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent, any other Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and each other Loan Document to which it is a party. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent, any other Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document, any related agreement or any document furnished hereunder or thereunder. The Agents shall not be required to keep themselves informed as to the performance or observance by the Borrower or any of its Subsidiaries of this Agreement, the Loan Documents or any other document referred to or provided for herein or to inspect the Properties or books of the Borrower or its Subsidiaries. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder, no Agent 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 Pillsbury Winthrop Shaw Pittman LLP is acting in this transaction as special counsel to the Administrative Agent with respect to this Agreement, RBS, as administrative agent for such lenders under the Non-Alabama Credit Agreement and to the Collateral Agent, only. 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.

83

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Borrower or any of its Subsidiaries, the Administrative Agent and the Collateral 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 Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the Collateral Agent, and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the Collateral Agent, and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the Collateral Agent, and the Administrative Agent under Section 12.03) allowed in such judicial proceeding; and

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

Section 12.02 Waivers; Amendments.

(a) No failure on the part of the Administrative Agent, any other Agent, any Issuer 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

86

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 Issuer and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by Section 12.02(b), and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any other Agent, any Lender or any Issuer may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any provision hereof nor any Security Instrument securing the payment or performance of the Obligations hereunder, nor any provision thereof, may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent, or the Collateral Agent (as applicable) with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Maximum Credit Amount of any Lender without the written consent of such Lender, (ii) increase the Borrowing Base without the written consent of each Lender, decrease or maintain the Borrowing Base without the consent of the Required Lenders, or modify in any manner Section 2.07 without the consent of each Lender (except as permitted pursuant to Section 2.07(j)), (iii) reduce the principal amount of any Loan or Letter of Credit Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, or reduce any other Obligations hereunder or under any other Loan Document, without the written consent of each Lender affected thereby, (iv) postpone the scheduled date of payment of the principal amount of any Loan or Letter of Credit Disbursement, or any interest thereon, or any fees payable hereunder, or any other Obligations hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Termination Date or the Maturity Date without the written consent of each Lender affected thereby, (v) change Section 4.01(b) or Section 4.01(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (vi) waive or amend Section 6.01, Section 8.13 or Section 10.02(c) 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 Guarantee Agreement), release all or substantially all of the collateral (other than as provided in Section 11.09), or reduce the percentage set forth in Section 8.13(a) to less than 85%, without the written consent of each Lender, (viii) change any of the provisions of this Section 12.02(b) or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or under any other Loan Documents or make any determination or grant any consent hereunder or any other Loan Documents, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, any other Agent, or any Issuer hereunder or under any other Loan Document without the prior written consent of the Administrative Agent, such other Agent or such Issuer, as the case may be, (ix) amend or modify the definition of Obligations to delete or

87

exclude any obligation or liability described therein without the written consent of each Lender, (x) amend the definitions of “Swap Agreement” or “Swap Counterparty” without the consent of each Swap Counterparty, or (xi) permit the Borrower to assign or transfer any of its rights or obligations under this Agreement or other Loan Documents without the written consent of each Lender. Notwithstanding the foregoing, any supplement to Schedule 7.14 (Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental schedule clearly marked as such, and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders.

Section 12.03 Expenses; Indemnity; Damage Waiver.

(a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and the Collateral Agent, including, without limitation, the reasonable fees, charges and disbursements of counsel and other outside consultants for the Administrative Agent and the Collateral Agent, the reasonable travel, photocopy, mailing, courier, telephone and other similar expenses and, in connection with the syndication of the credit facilities provided for herein, the preparation, negotiation, execution, delivery and administration (both before and after the execution hereof and including advice of counsel to the Administrative Agent and the Collateral Agent as to the rights and duties of the Administrative Agent and the Collateral Agent and the Lenders with respect thereto) of this Agreement and the other Loan Documents and any amendments, modifications or waivers of or consents related to the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all out-of-pocket costs, expenses, Taxes, assessments and other charges incurred by any Agent or any Lender in connection with any filing, registration, recording or perfection of any security interest contemplated by this Agreement or any Security Instrument or any other document referred to therein, (iii) all reasonable out-of-pocket expenses incurred by each Issuer in connection with the amendment of any Letter of Credit issued by such Issuer or any demand for payment thereunder, (iv) all reasonable out-of-pocket expenses incurred by any Agent, any Issuer or any Lender, including the fees, charges and disbursements of one (1) special New York legal counsel and one (1) local legal counsel for the Administrative Agent, the Collateral Agent, Issuer and Lenders, in connection with the enforcement or protection of its rights in connection with this Agreement or any other Loan Document, including its rights under this Section 12.03, or in connection with the Loans made or Letters of Credit issued hereunder, including, without limitation, all such reasonable out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit; provided, however, Borrower shall be obligated to pay such expenses for only counsel.

(b) THE BORROWER SHALL INDEMNIFY EACH AGENT, THE ARRANGERS, EACH ISSUER AND EACH LENDER, AND THE AFFILIATES, DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS OF ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON BEING CALLED AN “INDEMNITEE”) AGAINST, AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES AND RELATED EXPENSES, INCLUDING THE REASONABLE FEES, AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF (i) THE EXECUTION OR DELIVERY OF THIS

88

AGREEMENT OR ANY OTHER LOAN DOCUMENT CONTEMPLATED HEREBY, THE PERFORMANCE BY THE PARTIES HERETO OR THE PARTIES TO ANY OTHER LOAN DOCUMENT OF THEIR RESPECTIVE OBLIGATIONS HEREUNDER OR THEREUNDER OR THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREBY OR BY ANY OTHER LOAN DOCUMENT, (ii) THE FAILURE OF THE BORROWER OR ANY OF ITS SUBSIDIARIES TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING THIS AGREEMENT, OR WITH ANY GOVERNMENTAL REQUIREMENT, (iii) ANY INACCURACY OF ANY REPRESENTATION OR ANY BREACH OF ANY WARRANTY OR COVENANT OF THE BORROWER OR ANY GUARANTOR SET FORTH IN ANY OF THE LOAN DOCUMENTS OR ANY INSTRUMENTS, DOCUMENTS OR CERTIFICATIONS DELIVERED IN CONNECTION THEREWITH, (iv) ANY LOAN OR LETTER OF CREDIT OR THE USE OF THE PROCEEDS THEREFROM, INCLUDING, WITHOUT LIMITATION, ANY REFUSAL BY ANY ISSUER TO HONOR A DEMAND FOR PAYMENT UNDER A LETTER OF CREDIT ISSUED BY SUCH ISSUER IF THE DOCUMENTS PRESENTED IN CONNECTION WITH SUCH DEMAND DO NOT STRICTLY COMPLY WITH THE TERMS OF SUCH LETTER OF CREDIT, (v) THE OPERATIONS OF THE BUSINESS OF THE BORROWER AND ITS SUBSIDIARIES BY THE BORROWER AND ITS SUBSIDIARIES, (vi) ANY ASSERTION BY A THIRD PARTY THAT THE LENDERS WERE NOT ENTITLED TO RECEIVE THE PROCEEDS RECEIVED PURSUANT TO THE SECURITY INSTRUMENTS, (vii) THE BREACH OR NON-COMPLIANCE BY THE BORROWER OR ANY OF ITS SUBSIDIARIES WITH ANY ENVIRONMENTAL LAW APPLICABLE TO THE BORROWER OR ANY OF ITS SUBSIDIARIES, (viii) THE PRESENCE, USE, RELEASE, STORAGE, TREATMENT, DISPOSAL, GENERATION, THREATENED RELEASE, TRANSPORT, ARRANGEMENT FOR TRANSPORT OR ARRANGEMENT FOR DISPOSAL OF OIL, OIL AND GAS WASTES, SOLID WASTES OR HAZARDOUS SUBSTANCES ON OR AT ANY OF THE PROPERTIES OWNED OR OPERATED BY THE BORROWER OR ANY OF ITS SUBSIDIARIES IN VIOLATION OF ENVIRONMENTAL LAWS OR ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF HAZARDOUS MATERIALS ON OR FROM ANY PROPERTY OWNED OR OPERATED BY THE BORROWER OR ANY OF ITS SUBSIDIARIES IN VIOLATION OF ENVIRONMENTAL LAWS, (ix) ANY ENVIRONMENTAL LIABILITY RELATED IN ANY WAY TO THE BORROWER OR ANY OF ITS SUBSIDIARIES, (x) ANY OTHER VIOLATION OF ENVIRONMENTAL LAWS OR LAWS RELATING TO ANY HEALTH OR SAFETY CONDITION IN CONNECTION WITH THE LOAN DOCUMENTS, OR (xi) ANY ACTUAL OR PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY AND REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO, AND SUCH INDEMNITY SHALL EXTEND TO EACH INDEMNITEE NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF ONE OR MORE OF THE INDEMNITEES OR BY REASON OF STRICT LIABILITY IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNITEES; PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE

89

EXTENT THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES OR RELATED EXPENSES ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE.

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

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

(e) All amounts due under this Section 12.03 shall be payable within ten (10) Business Days of written demand therefor.

Section 12.04 Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of any Issuer that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section 12.04. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of any Issuer 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 Issuer 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 to an Eligible Assignee (including all or a portion of its Loan 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 for an assignment to a Lender or an Affiliate of a Lender or, if an Event of Default has occurred and is continuing, to any other Eligible Assignee; and

90

(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.

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

(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 Loan Commitment, the amount of the Loan Commitment 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;

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

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

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

(E) in connection with any permitted assignment of the rights and obligations of a Lender under this Agreement to any assignee, whether in whole or part, the effectiveness of such assignment shall be subject to a corresponding assignment made by such Lender to such assignee of such Lender’s rights and obligations under the Non-Alabama Credit Agreement such that, after giving effect to such assignments, each Lender’s Applicable Percentage under this Agreement is equal to each respective Lender’s “Applicable Percentage” (as such term is define in the Non-Alabama Credit Agreement) under the Non-Alabama Credit Agreement.

(iii) Subject to Section 12.04(b)(iv) and the acceptance and recording of an Assignment and Assumption, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and

91

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

(iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Maximum Credit Amount of, and principal amount of the Loans and Letter of Credit Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, each Issuer 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 Issuer 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 Issuer and each Lender.

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

(c) (i) Any Lender may, without the consent of the Borrower the Administrative Agent or any Issuer, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Loan Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent, each Issuer and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the

92

consent of the Participant, agree to any amendment, modification or waiver described in the proviso to Section 12.02 that affects such Participant. In addition such agreement must provide that the Participant be bound by the provisions of Section 12.03. Subject to Section 12.04(c)(ii), the Borrower agrees that each Participant shall be entitled to the benefits of Section 5.01, Section 5.02 and Section 5.03 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.04(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.08 as though it were a Lender, provided such Participant agrees to be subject to Section 4.01(c) as though it were a Lender.

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

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; 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.

Section 12.05 Survival; Revival; Reinstatement.

(a) All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, any other Agent, any Issuer or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Loan Commitments have not expired or terminated. The provisions of Section 5.01, Section 5.02, Section 5.03 and Section 12.03 and ARTICLE XI shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Loan Commitments or the termination of this Agreement, any other Loan Document or any provision hereof or thereof.

(b) To the extent that any payments on the Obligations or proceeds of any collateral are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law, common law or equitable cause, then to such extent, the Obligations so satisfied

93

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. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES HERETO AND THERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

(c) Except as provided in Section 6.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or electronic mail in portable document format (pdf) 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 limitations obligations under Swap Agreements) at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower or any 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

94

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

Section 12.09 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS. THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK EXCEPT TO THE EXTENT THAT UNITED STATES FEDERAL LAW PERMITS ANY LENDER TO CONTRACT FOR, CHARGE, RECEIVE, RESERVE OR TAKE INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE STATE WHERE SUCH LENDER IS LOCATED.

(a) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PARTY HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND DOES NOT PRECLUDE A PARTY FROM OBTAINING JURISDICTION OVER ANOTHER PARTY IN ANY COURT OTHERWISE HAVING JURISDICTION.

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

Constellation Energy Partners Closes Acquisition of Non-Operating

Interest in Woodford Shale

BALTIMORE, April 3, 2008 – Constellation Energy Partners LLC (NYSE Arca: CEP) today announced that it has closed its previously announced acquisition of non-operating interest in producing wells located in the Woodford Shale in Oklahoma from an affiliate of its sponsor, Constellation Energy (NYSE: CEG), for a purchase price of $53.4 million, subject to post-closing purchase price adjustments. The acquisition was fully funded with debt from the company’s revolving credit facility.

“This transaction is another demonstration of our commitment to our acquisition growth strategy and distribution stability,” said Stephen Brunner, chief executive officer of Constellation Energy Partners. “The Woodford Shale provides us with a foothold in an up-and-coming geographic area and access to low-risk production with limited exposure to increased capital commitments, operating expenses and resource demands. By purchasing 100 percent proved developed producing wells we have further solidified our expected cash flows.”

The company also announced revisions to its reserve based lending facility and borrowing base, effective March 28, 2008. The company’s new borrowing base is $240 million, with the capacity to expand to $265 million upon consideration of the Woodford Shale asset.

“Our ability to fund the acquisition through debt while maintaining a strong coverage ratio demonstrates our continued focus on maintaining financial flexibility,” said Charles Ward, chief financial officer of Constellation Energy Partners. “We were able to execute an acquisition during difficult market conditions. By increasing our borrowing base at the time of the

acquisition rather than when the asset base permits, we were able to proactively manage our costs to avoid the burden of fees and unnecessary carrying charges for unutilized funds.”

The company anticipates an additional expansion to the borrowing base during the second quarter 2008.

Operational Highlights

– Non-operating interest in 83 producing wells located in Coal and Hughes Counties in Oklahoma

– 100 percent proved developed producing

– Estimated proved reserves of 13.1 Bcfe (non-SEC reserve estimates internally calculated from third-party volume projections, as of Dec. 31, 2007 assuming a basis-adjusted price of $6.706 / MMbtu)

– Current net production is estimated at approximately 4.9 million cubic feet per day

– Average gross working interest of approximately 11.5 percent

– Average net revenue interest of approximately 9.2 percent

– 90 percent of the wells are operated by affiliates of Devon Energy Co. and Newfield Exploration Co., remaining wells are operated by three additional companies

– Average annual decline rate for these reserves estimated at 7 to 8 percent over 10 years

Financial Highlights

– Acquisition is expected to be immediately accretive to distributable cash flow per unit, beginning April 1, 2008.

– Net daily production forecast

^¡ 2008 estimate (based on April 1, 2008 to Dec. 31, 2008) – 1,100 to 1,150 MMcfe

^¡ 2009 estimate – 1,100 to 1,150 MMcfe

– Adjusted EBITDA impact

^¡ 2008 estimate (based on April 1, 2008 to Dec. 31, 2008)—$8.5 to $8.9 million

^¡ 2009 estimate—$8.5 to $8.9 million

– Projected maintenance capital expenditures of $2.0 to $2.5 million for 2008 (based on April 1, 2008 to Dec. 31, 2008). Production declines in the Woodford Shale asset should be offset by increased production from capital expenditures in the Cherokee Basin.

– Cash flow stability expected to be achieved by hedging through 2011. Hedges were implemented at acquisition announcement using a credit guarantee from the company’s sponsor, Constellation Energy.

– Funding cost (cost of debt) at the time of the transaction is a floating rate of less than 5 percent per annum.

Portfolio Impact

– Management expects to recommend to the board of managers maintaining a cash distribution of $0.5625 per outstanding common unit and Class A unit for the quarter ended March 31, 2008, or $2.25 per unit on an annualized basis. The distribution level is anticipated as a result of the impacts of drilling delays encountered during 2007 associated with weather and integration delays in the Cherokee Basin and pending the outcome of the arbitration relating to the termination of the Torch Energy Royalty Trust. Management will continue to evaluate distribution levels on a quarterly basis taking into consideration overall portfolio performance, acquisition integration and market outlook. All changes in distributions are subject to approval by the company’s board of managers.

– Portfolio reserve life decreases by one year to approximately 17 years with the addition of the Woodford asset.

Non-GAAP Measures

Adjusted EBITDA is a non-GAAP financial measure that is defined as net income (loss) plus interest (income) expense; depreciation, depletion and amortization; write-off of deferred financing fees; impairment of long-lived assets; (gain) loss on sale of assets; (gain) loss from equity investment; accretion of asset retirement obligation; unrealized (gain) loss on natural gas derivatives; and realized (gain) loss on cancelled natural gas derivatives.

Adjusted EBITDA is used by management to indicate (prior to the establishment of any cash reserves by our board of managers) the cash distributions we expect to pay our unitholders. Specifically, this financial measure indicates to investors whether or not we are generating cash

flow at a level that can sustain or support an increase in our quarterly distribution rates. Adjusted EBITDA is also used as a quantitative standard by our management and by external users of our financial statements such as investors, research analysts and others to assess the financial performance of our assets without regard to financing methods, capital structure or historical cost basis; the ability of our assets to generate cash sufficient to pay interest costs and support our indebtedness; and our operating performance and return on capital as compared to those of other companies in our industry, without regard to financing or capital structure. Adjusted EBITDA is not intended to represent cash flows for the period, nor is it presented as a substitute for net income, operating income, cash flows from operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP.
