- 21 -

(b) The Borrowing Base and the Monthly Commitment Reduction Amount shall be redetermined by the Agent on October 1, 2008 and thereafter semi-annually (on each April 1 and October 1 prior to the Commitment Termination Date) on the basis of information supplied by the Borrower in compliance with the provisions of this Agreement, including Reserve Reports, and all other relevant information available to the Agent and the Lenders.

The Borrower may make additional requests for which agreement will not be unreasonably withheld by the Agent. Notwithstanding the foregoing, the Agent may at its discretion redetermine the Borrowing Base and the Monthly Commitment Reduction Amount at any time and from time to time.

(c) Upon each determination of the Borrowing Base and the Monthly Commitment Reduction Amount, the Agent shall notify the Borrower orally (confirming such notice promptly in writing) of such determinations, and the amounts so communicated to the Borrower shall become effective upon such oral notification and shall remain in effect until the next subsequent determination of such amounts.

(d) The Borrowing Base shall represent the determination by the Lenders, in accordance with the applicable definitions and provisions herein contained and their customary lending practices for loans of this nature, of the value, for loan purposes, of the Mortgaged Properties, subject, in the case of any increase in the Borrowing Base, to the credit approval process of the Lenders. Furthermore, the Borrower acknowledges that the determination of the Borrowing Base contains an equity cushion (market value in excess of loan value), which is acknowledged by the Borrower to be essential for the adequate protection of the Lenders.

(e) Notwithstanding any other provision of this Section 2.9, the Borrower shall be entitled, by written request of the Borrower to the Agent at any time (any such request being irrevocable, absent written agreement of the Agent and the Required Lenders with respect to any subsequently requested increase in the Borrowing Base, which written agreement may be expressly conditioned on the payment of a fee by the Borrower to the Agent, for the account of the Lenders) to a reduction in the Borrowing Base.

2.10 Mandatory Prepayments. If at any time the Loan Balance and the L/C Exposure exceeds the Borrowing Base then in effect and exceeds the Borrowing Base, the Borrower shall, within 5 Business Days of notice from the Agent of such occurrence, (a) prepay, or make arrangements acceptable to the Agent for the prepayment of, the amount of such excess for application on the Loan Balance, (b) provide additional collateral, of character and value satisfactory to the Agent in its reasonable discretion, to secure the Obligations by the execution and delivery to the Agent of security instruments in form and substance satisfactory to the Agent in the exercise of its reasonable discretion, or (c) effect any combination of the alternatives described in clauses (a) and (b) of this Section and acceptable to the Agent in its reasonable discretion. In the event that a mandatory prepayment is required under this Section and the amount owed on the Notes plus accrued interest is less than the amount required to be prepaid, the Borrower shall repay the amount owed, plus accrued interest and, in accordance with the provisions of the relevant Letter of Credit Applications executed by the Borrower or otherwise to

- 22 -

the reasonable satisfaction of the Agent, deposit with the Agent, as additional collateral securing the Obligations, an amount of cash, in immediately available funds, equal to the L/C Exposure minus the Borrowing Base. The cash deposited with the Agent in satisfaction of the requirement provided in this Section may be invested, at the reasonable discretion of the Agent and then only at the express direction of the Borrower as to investment vehicle and maturity (which shall be no later than the latest expiry date of any then outstanding Letter of Credit), for the account of the Borrower in cash or cash equivalent investments offered by or through the Agent.

2.11 Voluntary Prepayments and Conversions of Loans. Subject to applicable provisions of this Agreement, the Borrower shall have the right at any time or from time to time to prepay Loans and to convert Loans of one type or with one Interest Period into Loans of another type or with a different Interest Period; provided, however, that (a) the Borrower shall give the Agent notice of each such prepayment or conversion of all or any portion of a LIBO Rate Loan no less than two Business Days prior to prepayment or conversion, (b) any LIBO Rate Loan may be prepaid or converted only on the last day of an Interest Period for such Loan, (c) the Borrower shall pay all accrued and unpaid interest on the amounts prepaid or converted, and (d) no such prepayment or conversion shall serve to postpone the repayment when due of any Obligation.

2.12 Commitment Fee. In addition to interest on the Notes as provided herein and all other fees payable hereunder and to compensate the Lenders for maintaining funds available, the Borrower shall pay to the Agent for the account of the Lenders, in immediately available funds, on the first day of April, 2008, and on the first day of each third calendar month thereafter during the Commitment Period, a fee in the amount of 0.375% per annum, calculated on the basis of a year of 365 or 366 days, as the case may be, for the actual days elapsed (including the first day but excluding the last day), on the average daily amount of the Available Commitment during the preceding quarterly period.

2.13 RESERVED.

2.14 Letter of Credit Fee. In addition to interest on the Notes as provided herein and all other fees payable hereunder, the Borrower agrees to pay to the Agent for the account of the Lenders, on the date of issuance of each Letter of Credit, a fee equal to the greater of $500 or 2.00% calculated on the basis of a year of 365 or 366 days, as the case may be, for the actual days elapsed (including the first day but excluding the last day), on the face amount of such Letter of Credit during the period for which such Letter of Credit is issued; provided, however, in the event such Letter of Credit is canceled prior to its original expiry date or a payment is made by the Agent on behalf of the Lenders with respect to such Letter of Credit, the Agent shall, within 30 days after such cancellation or the making of such payment, rebate to the Borrower the unearned portion of such fee. The Borrower also agrees to pay to Guaranty, on demand and solely for its account, its customary letter of credit transactional fees, including, without limitation, amendment fees, payable with respect to each Letter of Credit.

2.15 Loans to Satisfy Obligations of Borrower. The Lenders may, but shall not be obligated to, but only if an Event of Default exists, make Loans for the benefit of the Borrower and apply proceeds thereof to the satisfaction of any condition, warranty, representation, or covenant of the Borrower contained in this Agreement or any other Loan Document. Any such Loan shall be evidenced by the Notes and shall be made as a Floating Rate Loan.

- 23 -

2.16 Security Interest in Accounts; Right of Offset. As security for the payment and performance of the Obligations, the Borrower hereby transfers, assigns, and pledges to the Agent for the benefit of the Lenders, and grants to the Agent for the benefit of the Lenders, a security interest in all funds of the Borrower now or hereafter or from time to time on deposit with the Agent and such Lenders, with such interest to be retransferred, reassigned, and/or released by the Agent and each Lender, as the case may be, at the expense of the Borrower upon payment in full and complete performance by the Borrower of all Obligations. All remedies as secured party or assignee of such funds shall be exercisable by the Agent during the existence of the occurrence of any Event of Default, regardless of whether the exercise of any such remedy would result in any penalty or loss of interest or profit with respect to any withdrawal of funds deposited in a time deposit account prior to the maturity thereof. Furthermore, the Borrower hereby grants to the Agent and each Lender the right, exercisable during the existence of an Event of Default, of offset or banker’s lien against all funds of the Borrower now or hereafter or from time to time on deposit with the Agent and each Lender, regardless of whether the exercise of any such remedy would result in any penalty or loss of interest or profit with respect to any withdrawal of funds deposited in a time deposit account prior to the maturity thereof, provided that such Obligation shall have matured, whether by acceleration of maturity or otherwise.

2.17 General Provisions Relating to Interest. (a) It is the intention of the parties hereto to comply strictly with the usury laws of the State of Texas and the United States of America. In this connection, there shall never be collected, charged, or received on the sums advanced hereunder interest in excess of that which would accrue at the Highest Lawful Rate. The Borrower agrees that, to the extent the Highest Lawful Rate is determined with reference to the laws of the State to Texas, the Highest Lawful Rate shall be the “weekly” rate as defined in Chapter 303 of the Texas Finance Code (Vernon’s 1999), provided that the Lender may, at its election, substitute for the “weekly” rate the “annualized” or “quarterly” rate, as such terms are defined in the aforesaid statute, upon the giving of notices provided for in such statute and effective upon the giving of such notices. The Lender may also rely, to the extent permitted by applicable laws of the State of Texas or the United States of America, on alternative maximum rates of interest under other laws of the State of Texas or the United States of America applicable to the Lender, if greater.

(b) Notwithstanding anything herein or in the Notes, or any of them, to the contrary, during any Limitation Period, the interest rate to be charged on amounts evidenced by the Notes shall be the Highest Lawful Rate, and the obligation, if any, of the Borrower for the payment of fees or other charges deemed to be interest under applicable law shall be suspended. During any period or periods of time following a Limitation Period, to the extent permitted by applicable laws of the State of Texas or the United States of America, the interest rate to be charged hereunder shall remain at the Highest Lawful Rate until such time as there has been paid to the Agent for the account of the Lenders (i) the amount of interest in excess of that accruing at the Highest Lawful Rate that the Agent would have received during the Limitation Period had the interest rate remained at the otherwise applicable rate, and (ii) all interest and fees otherwise payable to the Agent but for the effect of such Limitation Period.

- 24 -

(c) If, under any circumstances, the aggregate amounts paid on the Notes, or any of them, or under this Agreement or any other Loan Document include amounts which by law are deemed interest and which would exceed the amount permitted if the Highest Lawful Rate were in effect, the Borrower stipulates that such payment and collection will have been and will be deemed to have been, to the extent permitted by applicable laws of the State of Texas or the United States of America, the result of mathematical error on the part of the Borrower, the Agent and the Lenders; and the Agent, on behalf of itself and the Lenders, shall promptly refund the amount of such excess (to the extent only of such interest payments in excess of that which would have accrued and been payable on the basis of the Highest Lawful Rate) upon discovery of such error by the Agent or notice thereof from the Borrower. In the event that the maturity of any Obligation is accelerated, by reason of an election by the Agent or otherwise, or in the event of any required or permitted prepayment, then the consideration constituting interest under applicable laws may never exceed the Highest Lawful Rate; and excess amounts paid which by law are deemed interest, if any, shall be credited by the Agent on the principal amount of the Obligations, or if the principal amount of the Obligations shall have been paid in full, refunded to the Borrower.

(d) All sums paid, or agreed to be paid, to the Agent, for the account of the Lenders, for the use, forbearance and detention of the proceeds of any advance hereunder shall, to the extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full term hereof until paid in full so that the actual rate of interest is uniform but does not exceed the Highest Lawful Rate throughout the full term hereof.

2.18 Yield Protection. (a) Without limiting the effect of the other provisions of this Section (but without duplication), the Borrower shall pay to the Agent, for the account of the Lenders, from time to time such amounts as the Agent or the Lenders may determine are necessary to compensate the Lenders for any Additional Costs incurred by the Lenders.

(b) Without limiting the effect of the other provisions of this Section (but without duplication), the Borrower shall pay to the Agent, for the account of the Lenders, from time to time on request such amounts as the Agent or the Lenders may determine are necessary to compensate the Lenders for any costs attributable to the maintenance by the Lenders (or any Applicable Lending Office), pursuant to any Regulatory Change, of capital in respect of the Commitment, such compensation to include, without limitation, an amount equal to any reduction of the rate of return on assets or equity of the Lenders (or any Applicable Lending Office) to a level below that which the Lenders (or any Applicable Lending Office) could have achieved but for such Regulatory Change.

(c) Without limiting the effect of the other provisions of this Section (but without duplication), in the event that any Requirement of Law or Regulatory Change or the compliance by the Agent or the Lenders therewith shall (i) impose, modify, or hold applicable any reserve, special deposit, or similar requirement against any Letter of Credit or obligation to issue Letters of Credit, or (ii) impose upon the Agent or the Lenders any other condition regarding any Letter of Credit or obligation to issue Letters of Credit, and the result of any such event shall be to increase the cost to the Lenders of issuing or maintaining any Letter of Credit or obligation to issue Letters of Credit or any liability with respect to payments by the Lenders under Letters of Credit, or to reduce any amount receivable in connection therewith, then within

- 25 -

15 days of demand by the Agent, the Borrower shall pay to the Agent, for the account of the Lenders, from time to time as specified by the Agent, additional amounts which shall be sufficient to compensate the Lenders for such increased cost or reduced amount receivable.

(d) Without limiting the effect of the other provisions of this Section (but without duplication), the Borrower shall pay to the Agent, for the account of the Lenders, such amounts as shall be sufficient in the reasonable opinion of the Agent to compensate the Lenders for any loss, cost, or expense incurred by and as a result of:

(i) any payment, prepayment, or conversion by the Borrower of a LIBO Rate Loan on a date other than the last day of an Interest Period for such Loan; or

(ii) any failure by the Borrower to borrow a LIBO Rate Loan on the date for such borrowing specified in the relevant Borrowing Request;

such compensation to include, without limitation, with respect to any LIBO Rate Loan, an amount equal to the excess, if any, of (A) the amount of interest which would have accrued on the principal amount so paid, prepaid, converted, or not borrowed for the period from the date of such payment, prepayment, conversion, or failure to borrow to the last day of the then current Interest Period for such Loan (or, in the case of a failure to borrow, the Interest Period for such Loan which would have commenced on the date of such failure to borrow) at the applicable rate of interest for such Loan provided for herein over (B) the interest component (as reasonably determined by the Agent) of the amount (as reasonably determined by the Agent) the Lenders would have bid in the London interbank market for Dollar deposits of amounts comparable to such principal amount and maturities comparable to such period; provided, however, that the Agent, on behalf of the Lenders, shall be limited to recover their actual losses and not anticipated profits.

(e) Determinations by the Agent or the Lenders for purposes of this Section of the effect of any Regulatory Change on capital maintained, their costs or rate of return, maintaining Loans, issuing Letters of Credit, the Lenders’ obligations to make Loans and issue Letters of Credit, or on amounts receivable by them in respect of Loans, Letters of Credit, or such obligations, and the additional amounts required to compensate the Lenders under this Section, shall be rebuttable presumptions of the additional amounts due, provided that such determinations are made on a reasonable basis. The Agent shall furnish the Borrower with a certificate setting forth in reasonable detail the basis and amount of increased costs incurred or reduced amounts receivable as a result of any such event, and the statements set forth therein shall be rebuttable presumptions of the additional amounts due. The Agent, on behalf of the Lenders, shall (i) notify the Borrower, as promptly as practicable after the Agent obtains knowledge of any Additional Costs or other sums payable pursuant to this Section and determines to request compensation therefore, of any event occurring after the Closing Date which will entitle the Lenders to compensation pursuant to this Section; provided that the Borrower shall not be obligated for the payment of any Additional Costs or other sums payable pursuant to this Section after the earlier of (A) the Final Maturity (provided that the Obligations have been paid in full) and (B) the expiration of the Commitment (provided that the Obligations

- 26 -

have been paid in full) to the extent such Additional Costs or other sums accrued more than 90 days prior to the date upon which the Borrower was given such notice; and (ii) designate a different Applicable Lending Office for the Loans of the Lenders affected by such event if such designation will avoid the need for or reduce the amount of such compensation and will not, in the sole opinion of the Lenders, be materially disadvantageous to the Lenders. If the Lenders request compensation from the Borrower under this Section, the Borrower may, by notice to the Agent, require that the Loans by the Lenders of the type with respect to which such compensation is requested be converted into Floating Rate Loans in accordance with Section 2.11. Any compensation requested pursuant to this Section shall be due and payable to the Agent, for the account of the Lenders, within fifteen days of delivery of any such notice by the Agent to the Borrower.

(f) Each of the Lenders agree that it shall not request, and the Borrower shall not be obligated to pay, any Additional Costs or other sums payable pursuant to this Section unless similar additional costs and other sums payable are also generally assessed by such Lender against other customers of such Lender similarly situated where such customers are subject to documents providing for such assessment.

2.19 Limitation of Types of Loans. Anything herein to the contrary notwithstanding, no more than seven separate Loans shall be outstanding at any one time, with, for purposes of this Section, all Floating Rate Loans constituting one Loan and all LIBO Rate Loans for the same Interest Period constituting one Loan. Anything herein to the contrary notwithstanding, if, on or prior to the determination of any interest rate for any LIBO Rate Loan for any Interest Period therefor:

(a) the Lenders determine (which determination shall be conclusive) that quotations of interest rates for the deposits referred to in the definition of “LIBO Rate” in Section 1.2 are not being provided in the relevant amounts or for the relevant maturities for purposes of determining the rate of interest for such Loan as provided in this Agreement; or

(b) the Lenders determine (which determination shall be conclusive) that the rates of interest referred to in the definition of “LIBO Rate” in Section 1.2 upon the basis of which the rate of interest for such Loan for such Interest Period is to be determined do not accurately reflect the cost to the Lenders of making or maintaining such Loan for such Interest Period,

then the Agent shall give the Borrower prompt notice thereof; and so long as such condition remains in effect, the Lenders shall be under no obligation to make LIBO Rate Loans or to convert Loans of any other type into LIBO Rate Loans, and the Borrower shall, on the last day of the then current Interest Period for each outstanding LIBO Rate Loan, either prepay such LIBO Rate Loan or convert such Loan into another type of Loan in accordance with Section 2.11. Before giving such notice pursuant to this Section, the Agent will designate a different available Applicable Lending Office for LIBO Rate Loans or take such other action as the Borrower may request if such designation or action will avoid the need to suspend the obligation of the Lenders to make LIBO Rate Loans hereunder and will not, in the opinion of the Agent, be materially disadvantageous to the Agent or the Lenders.

- 27 -

2.20 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for the Lenders or their Applicable Lending Office to (a) honor its obligation to make any type of LIBO Rate Loans hereunder, or (b) maintain any type of LIBO Rate Loans hereunder, then the Agent shall promptly notify the Borrower thereof; and the obligation of the Lenders hereunder to make such type of LIBO Rate Loans and to convert other types of Loans into LIBO Rate Loans of such type shall be suspended until such time as the Lenders may again make and maintain LIBO Rate Loans of such type, and the outstanding LIBO Rate Loans of such type shall be converted into Floating Rate Loans in accordance with Section 2.11. Before giving such notice pursuant to this Section, the Agent will designate a different available Applicable Lending Office for LIBO Rate Loans or take such other action as the Borrower may request if such designation or action will avoid the need to suspend the obligation of the Lenders to make LIBO Rate Loans and will not, in the opinion of the Agent, be disadvantageous to the Agent or the Lenders.

2.21 Regulatory Change. In the event that by reason of any Regulatory Change, the Lenders (a) incur Additional Costs based on or measured by the excess above a specified level of the amount of a category of deposits or other liabilities of the Lenders which includes deposits by reference to which the interest rate on any LIBO Rate Loan is determined as provided in this Agreement or a category of extensions of credit or other assets of such Lenders which includes any LIBO Rate Loan, or (b) becomes subject to restrictions on the amount of such a category of liabilities or assets which it may hold, then, at the election of the Agent with notice to the Borrower, the obligation of the Lenders to make such LIBO Rate Loans and to convert Floating Rate Loans into such LIBO Rate Loans shall be suspended until such time as such Regulatory Change ceases to be in effect, and all such outstanding LIBO Rate Loans shall be converted into Floating Rate Loans in accordance with Section 2.11.

2.22 Limitations on Interest Periods. Each Interest Period selected by the Borrower (a) which commences on the last Business Day of a calendar month (or, with respect to any LIBO Rate Loan, any day for which there is no numerically corresponding day in the appropriate subsequent calendar month) shall end on the last Business Day of the appropriate subsequent calendar month, (b) which would otherwise end on a day which is not a Business Day shall end on the next succeeding Business Day (or, with respect to any LIBO Rate Loan, if such next succeeding Business Day falls in the next succeeding calendar month, on the next preceding Business Day), (c) which would otherwise commence before and end after Final Maturity shall end on Final Maturity, and (d) shall have a duration of not less than one month, as to any LIBO Rate Loan, and, if any Interest Period would otherwise be a shorter period, the relevant Loan shall be a Floating Rate Loan during such period.

2.23 Letters in Lieu of Transfer Orders. The Agent agrees that none of the letters in lieu of transfer or division orders provided by the Borrower will be sent to the addressees thereof prior to the occurrence of an Event of Default, at which time the Agent may, at its option and in addition to the exercise of any of its other rights and remedies, send any or all of such letters.

2.24 Power of Attorney. The Borrower hereby designates the Agent as its agent and attorney-in-fact, to act in its name, place, and stead for the purpose of completing and, upon the occurrence of an Event of Default, delivering any and all of the letters in lieu of transfer or division orders delivered by the Borrower to the Agent, including completing any blanks

- 28 -

contained in such letters and attaching exhibits thereto describing the relevant Collateral. The Borrower hereby ratifies and confirms all that the Agent shall lawfully do or cause to be done by virtue of this power of attorney and the rights granted with respect to such power of attorney. This power of attorney is coupled with the interests of the Agent (for the benefit of the Lenders) in the Collateral, shall commence and be in full force and effect as of the Closing Date and shall remain in full force and effect and shall be irrevocable so long as any Obligation remains outstanding or unpaid or any Commitment exists. The powers conferred on the Agent by this appointment are solely to protect the interests of the Agent and the Lenders under the Loan Documents and shall not impose any duty upon the Agent to exercise any such powers. The Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers and shall not be responsible to the Borrower or any other Person for any act or failure to act with respect to such powers, except for gross negligence or willful misconduct.

ARTICLE IV

REPRESENTATIONS AND WARRANTIES

To induce the Agent and the Lenders to enter into this Agreement and to make the Loans and issue Letters of Credit, the Borrower represents and warrants to the Agent and the Lenders (which representations and warranties shall survive the delivery of the Notes) that:

4.1 Due Authorization. The execution and delivery by the Borrower of this Agreement and the borrowings hereunder, the execution and delivery by the Borrower of the Notes, the repayment of the Notes and interest and fees provided for in the Notes and this Agreement, the execution and delivery of the Security Instruments by the Borrower and the performance of all obligations of the Borrower under the Loan Documents, are within the power of the Borrower, have been duly authorized by all necessary limited liability company action by the Borrower, and do not and will not (a) require the consent of any Governmental Authority, (b) contravene or conflict with any Requirement of Law, (c) contravene or conflict with any indenture, instrument, or other agreement to which the Borrower is a party or by which any Property of the Borrower may be presently bound or encumbered, except where such contravention or conflict would not individually or in the aggregate result in a Material Adverse

- 31 -

Effect, or (d) result in or require the creation or imposition of any Lien in, upon or of any Property of the Borrower under any such indenture, instrument, or other agreement, other than the Loan Documents.

4.2 Limited Liability Company Existence. The Borrower is a limited liability company duly organized, legally existing, and in good standing under the laws of its state of formation and is duly qualified as foreign limited liability company and is in good standing in all jurisdictions wherein the ownership of Property or the operation of its business necessitates same, other than those jurisdictions wherein the failure to so qualify will not have a Material Adverse Effect.

4.3 Valid and Binding Obligations. All Loan Documents, when duly executed and delivered by the Borrower, will be the legal, valid, and binding obligations of the Borrower, enforceable against the Borrower in accordance with their respective terms except as enforceability may be limited by applicable bankruptcy, insolvency, or similar laws affecting the enforcement of creditors’ rights generally or by equitable principles relative to enforceability.

4.4 Security Instruments. The provisions of each Security Instrument are effective to create in favor of the Agent, for the benefit of the Lenders, a legal, valid, and enforceable Lien in all right, title, and interest of the Borrower in the Collateral described therein, except as enforceability may be limited by applicable bankruptcy, insolvency, or similar laws affecting the enforcement of creditors’ rights generally or by equitable principles relative to enforceability, which Liens, assuming the accomplishment of recording and filing in accordance with applicable laws prior to the intervention of rights of other Persons, shall constitute fully perfected first-priority Liens on all right, title, and interest of the Borrower in the Collateral described therein subject to Permitted Liens.

4.5 Title to Assets. The Borrower has good and indefeasible title to all of its interests in its Properties then owned by it, free and clear of all Liens except Permitted Liens.

4.6 No Material Misstatements. As of the Closing Date, no information, exhibit, statement, or report furnished to the Lender by or at the direction of the Borrower in connection with this Agreement contains any material misstatement of fact or omits to state a material fact or any fact necessary to make the statements contained therein not misleading as of the date made or deemed made.

4.7 Liabilities, Litigation, and Restrictions. As of the Closing Date, other than as reflected and reported in Borrower’s Financial Statements as of March 31, 2006, including the due to related parties, the Borrower has no liabilities, direct, or contingent, which would result in a Material Adverse Effect, no litigation or other action of any nature affecting the Borrower is pending before any Governmental Authority or, to the best knowledge of the Borrower, threatened against or affecting the Borrower which might reasonably be expected to result in any material impairment of its ownership of any Collateral or have a Material Adverse Effect. To the best knowledge of the Borrower, after due inquiry, no unusual or unduly burdensome restriction, restraint or hazard exists by contract, Requirement of Law, or otherwise relative to the business or operations of the Borrower or the ownership and operation of the Collateral would result in a Material Adverse Effect, other than such as relate generally to Persons engaged in business activities similar to those conducted by the Borrower.

- 32 -

4.8 Authorizations; Consents. Except as expressly contemplated by this Agreement, no authorization, consent, approval, exemption, franchise, permit, or license of, or filing with, any Governmental Authority or any other Person is required to authorize or is otherwise required in connection with the valid execution and delivery by the Borrower of the Loan Documents or any instrument contemplated hereby, the repayment by the Borrower of the Notes and interest and fees provided in the Notes and this Agreement, or the performance by the Borrower of the Obligations.

4.9 Compliance with Laws. The Borrower and its Property, including, without limitation, the Mortgaged Property, are in compliance with all material applicable Requirements of Law, including, without limitation, Environmental Laws, the Natural Gas Policy Act of 1978, as amended, and ERISA, except to the extent non-compliance with any such Requirements of Law could not reasonably be expected to have a Material Adverse Effect.

4.10 ERISA. No Reportable Event has occurred with respect to any Single Employer Plan, and each Single Employer Plan has complied with and been administered in all material respects in accordance with applicable provisions of ERISA and the Code. To the knowledge of the Borrower, (a) no Reportable Event has occurred with respect to any Multiemployer Plan, and (b) each Multiemployer Plan has complied with and been administered in all material respects with applicable provisions of ERISA and the Code. The present value of all benefits vested under each Single Employer Plan maintained by the Borrower or any Commonly Controlled Entity (based on the assumptions used to fund such Plan) did not, as of the last annual valuation date applicable thereto, exceed the value of the assets of such Plan allocable to such vested benefits. Neither the Borrower nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan for which there is any withdrawal liability. As of the most recent valuation date applicable to any Multiemployer Plan, neither the Borrower nor any Commonly Controlled Entity would become subject to any liability under ERISA if the Borrower or such Commonly Controlled Entity were to withdraw completely from such Multiemployer Plan.

THE AGENT

8.1 Appointment. Each Lender hereby designates and appoints the Agent as the agent of such Lender under this Agreement and the other Loan Documents. Each Lender authorizes the Agent, as the agent for such Lender, to take such action on behalf of such Lender under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to the Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement or in any other Loan Document, the Agent shall not have any duties or responsibilities except those expressly set forth herein or in any other Loan Document or any fiduciary relationship with any Lender; and no implied covenants, functions, responsibilities, duties, obligations, or liabilities on the part of the Agent shall be read into this Agreement or any other Loan Document or otherwise exist against the Agent.

8.2 Waivers, Amendments. The provisions of this Agreement and of each other Loan Document may from time to time be amended, modified or waived, if such amendment, modification, or waiver is in writing and consented to by the Borrower and the Required Lenders; provided, however, that no such amendment, modification or waiver would: (a) modify any requirement hereunder that any particular action be taken by all of the Lenders or by the Required Lenders unless consented to by each Lender; (b) modify this Section 8.2, change the definition of “Required Lenders”, or change the Commitment Amount or Percentage Share of any Lender, reduce the fees described in Article II, extend the Commitment Termination Date or

- 48 -

Final Maturity, release any Security Instrument or Lien, or initiate any foreclosure, enforcement or collection procedure without the consent of each Lender; (c) extend the due date for, or reduce the amount of any scheduled repayment or prepayment of principal of or interest on any Loan, without the consent of the holder of the Note(s) evidencing such Loan; (d) affect, adversely the interests, rights, or obligations of the Agent without the consent of the Agent; or (e) modify the Borrowing Base or modify the monthly amount by which the Borrowing Base shall be reduced.

8.3 Delegation of Duties. The Agent may execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Agent shall not be responsible to any Lender for the negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care.

8.4 Exculpatory Provisions. Neither the Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates shall be (a) required to initiate or conduct any litigation or collection proceedings hereunder, except with the concurrence of the Required Lenders and contribution by each Lender of its Percentage Share of costs reasonably expected by the Agent to be incurred in connection therewith, (b) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except for gross negligence or willful misconduct of the Agent or such Person), or (c) responsible in any manner to any Lender for any recitals, statements, representations or warranties made by the Borrower or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Agent under or in connection with, this Agreement or any other Loan Document, or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of the Borrower to perform its obligations hereunder or thereunder. The Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of the Borrower.

8.5 Reliance by Agent. The Agent shall be entitled to rely, and shall be fully protected in relying, upon any Note, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including counsel to the Borrower), independent accountants and other experts selected by the Agent. The Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless and until a written notice of assignment, negotiation, or transfer thereof shall have been received by the Agent. The Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate and contribution by each Lender of its Percentage Share of costs reasonably expected by the Agent to be incurred in connection therewith. The Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders. Such request and any action taken or failure to act pursuant thereto

- 49 -

shall be binding upon the Lenders and all future holders of the Notes. In no event shall the Agent be required to take any action that exposes the Agent to personal liability or that is contrary to any Loan Document or applicable Requirement of Law.

8.6 Notice of Default. The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default unless the Agent has received notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default.” In the event that the Agent receives such a notice, the Agent shall promptly give notice thereof to the Lenders. The Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders; provided that unless and until the Agent shall have received such directions, subject to the provisions of Section 7.2, the Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders. In the event that the officer of the Agent primarily responsible for the lending relationship with the Borrower or the officer of any Lender primarily responsible for the lending relationship with the Borrower becomes aware that a Default or Event of Default has occurred and is continuing, the Agent or such Lender, as the case may be, shall use its good faith efforts to inform the other Lenders and/or the Agent, as the case may be, promptly of such occurrence. Notwithstanding the preceding sentence, failure to comply with the preceding sentence shall not result in any liability to the Agent or any Lender.

8.7 Non-Reliance on Agent and Other Lenders. Each Lender expressly acknowledges that neither the Agent nor any other Lender nor any of their respective officers, directors, employees, agents, attorneys-in-fact or affiliates has made any representation or warranty to such Lender and that no act by the Agent or any other Lender hereafter taken, including any review of the affairs of the Borrower, shall be deemed to constitute any representation or warranty by the Agent or any Lender to any other Lender. Each Lender represents to the Agent that it has, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, condition (financial and otherwise) and creditworthiness of the Borrower and the value of the Collateral and other Properties of the Borrower and has made its own decision to enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon the Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, condition (financial and otherwise) and creditworthiness of the Borrower and the value of the Collateral and other Properties of the Borrower. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Agent hereunder, the Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial and otherwise), or creditworthiness of the Borrower or the value of the Collateral or other Properties of the Borrower which may come into the possession of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates.

- 50 -

8.8 Indemnification. EACH LENDER AGREES TO INDEMNIFY THE AGENT AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT AND AFFILIATES (TO THE EXTENT NOT REIMBURSED BY THE BORROWER AND WITHOUT LIMITING THE OBLIGATION OF THE BORROWER TO DO SO), RATABLY ACCORDING TO THE PERCENTAGE SHARE OF SUCH LENDER, FROM AND AGAINST ANY AND ALL LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND WHATSOEVER WHICH MAY AT ANY TIME (INCLUDING ANY TIME FOLLOWING THE PAYMENT AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT) BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE AGENT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES IN ANY WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY OTHER DOCUMENT CONTEMPLATED OR REFERRED TO HEREIN OR THE TRANSACTIONS CONTEMPLATED HEREBY OR ANY ACTION TAKEN OR OMITTED BY THE AGENT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES UNDER OR IN CONNECTION WITH ANY OF THE FOREGOING, INCLUDING ANY LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS IMPOSED, INCURRED OR ASSERTED AS A RESULT OF THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES; PROVIDED THAT NO LENDER SHALL BE LIABLE FOR THE PAYMENT OF ANY PORTION OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING SOLELY FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE AGENT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES. THE AGREEMENTS IN THIS SECTION SHALL SURVIVE THE PAYMENT AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT.

8.9 Restitution. Should the right of the Agent or any Lender to realize funds with respect to the Obligations be challenged and any application of such funds to the Obligations be reversed, whether by Governmental Authority or otherwise, or should the Borrower otherwise be entitled to a refund or return of funds distributed to the Lenders in connection with the Obligations, the Agent or such Lender, as the case may be, shall promptly notify the Lenders of such fact. Not later than Noon, Central Standard or Central Daylight Savings Time, as the case may be, of the Business Day following such notice, each Lender shall pay to the Agent an amount equal to the ratable share of such Lender of the funds required to be returned to the Borrower. The ratable share of each Lender shall be determined on the basis of the percentage of the payment all or a portion of which is required to be refunded originally distributed to such Lender, if such percentage can be determined, or, if such percentage cannot be determined, on the basis of the Percentage Share of such Lender. The Agent shall forward such funds to the Borrower or to the Lender required to return such funds. If any such amount due to the Agent is made available by any Lender after Noon, Central Standard or Central Daylight Savings Time, as the case may be, of the Business Day following such notice, such Lender shall pay to the Agent (or the Lender required to return funds to the Borrower, as the case may be) for its own account interest on such amount at a rate equal to the Federal Funds Rate for the period from and including the date on which restitution to the Borrower is made by the Agent (or the Lender required to return funds to the Borrower, as the case may be) to but not including the date on which such Lender failing to timely forward its share of funds required to be returned to the Borrower shall have made its ratable share of such funds available.

- 51 -

8.10 Agent in Its Individual Capacity. The Agent and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrower as though the Agent were not the agent hereunder. With respect to any Note issued to the Lender serving as the Agent, the Agent shall have the same rights and powers under this Agreement as a Lender and may exercise such rights and powers as though it were not the Agent. The terms “Lender” and “Lenders” shall include the Agent in its individual capacity.

8.11 Successor Agent. The Agent may resign as Agent upon ten (10) days’ notice to the Lenders and the Borrower. If the Agent shall resign as Agent under this Agreement and the other Loan Documents, Lenders for which the Percentage Shares aggregate at least fifty-one percent (51%) shall appoint from among the Lenders a successor agent for the Lenders, subject to the reasonable consent of the Borrower, whereupon such successor agent shall succeed to the rights, powers and duties of the Agent. The term “Agent” shall mean such successor agent effective upon its appointment. The rights, powers, and duties of the former Agent as Agent shall be terminated, without any other or further act or deed on the part of such former Agent or any of the parties to this Agreement or any holders of the Notes. After the removal or resignation of any Agent hereunder as Agent, the provisions of this Article VIII and those of any Section hereof relating to the Agent, including Section 5.17, Section 5.18, and Section 5.22, shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement and the other Loan Documents.

8.12 Applicable Parties. The provisions of this Article are solely for the benefit of the Agent and the Lenders, and the Borrower shall not have any rights as a third party beneficiary or otherwise under any of the provisions of this Article. In performing functions and duties hereunder and under the other Loan Documents, the Agent shall act solely as the agent of the Lenders and does not assume, nor shall it be deemed to have assumed, any obligation or relationship of trust or agency with or for the Borrower or any legal representative, successor, and assign of the Borrower.

8.13 Subordination Agreements. In furtherance of the authority granted to the Agent in Section 8.1 and elsewhere in this Agreement, each of the Lenders authorizes the Agent to execute and, by such execution, to bind such Lender to the terms of each of the Subordination Agreements and agrees to be bound by the terms of each of the Subordination Agreements as fully as if a signatory thereto.

(iii) written notice of such assignment and delegation together with payment instructions, addresses and related information with respect to such Assignee Lender, shall have been given to the Borrower and the Agent by such Lender and such Assignee Lender,

(iv) such Assignee Lender shall have executed and delivered to the Borrower and the Agent a Lender Assignment Agreement, accepted by the Borrower and the Agent and attached hereto as Exhibit VII, and

- 53 -

principal amount of the Loans and Commitments retained by the assignor Lender hereunder (such Notes to be in exchange for, but not in payment of, those Notes then held by such assignor Lender).

Accrued interest on that part of the predecessor Notes evidenced by the new Notes, and accrued fees, shall be paid as provided in the Lender Assignment Agreement. Accrued interest on that part of the predecessor Notes evidenced by the replacement Notes shall be paid to the assignor Lender. Accrued interest and accrued fees shall be paid at the same time or times provided in the predecessor Notes and in this Agreement. Such assignor Lender or such Assignee Lender must also pay a processing fee to the Agent upon delivery of any Lender Assignment Agreement in the amount of $3,000. Any attempted assignment and delegation not made in accordance with this Section 9.1 shall be null and void.

(b) Participations. Any Lender, with the prior written consent of the Borrower in its sole discretion, may at any time sell to one or more commercial banks (each of such commercial banks being herein called a “Participant”) participating interests in any of the Loans, Commitments, or other interests of such Lender hereunder; provided, however, that (a) no participation contemplated in this Section 9.1 shall relieve such Lender from its Commitments or its other obligations hereunder or under any other Loan Document, (b) such Lender shall remain solely responsible for the performance of its Commitments and such other obligations, (c) the Borrower and the Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and each of the other Loan Documents, (d) no Participant shall be entitled to require such Lender to take or refrain from taking any action hereunder or under any other Loan Document.

9.2 Survival of Representations, Warranties, and Covenants. All representations and warranties of the Borrower and all covenants and agreements herein made shall survive the execution and delivery of the Notes and the Security Instruments and shall remain in force and effect so long as any Obligation is outstanding or any Commitment exists.

9.3 Notices and Other Communications. Except as to oral notices expressly authorized herein, which oral notices shall be confirmed in writing, all notices, requests, and communications hereunder shall be in writing (including facsimile or other electronic form). Unless otherwise expressly provided herein, any such notice, request, demand, or other communication shall be deemed to have been duly given or made when delivered by hand, or, in the case of delivery by mail, when deposited in the mail, certified mail, return receipt requested, postage prepaid, or, in the case of facsimile or other electronic notice, when receipt thereof is acknowledged orally or by written confirmation report, addressed as follows:

Any party may, by proper written notice hereunder to the others, change the individuals or addresses to which such notices to it shall thereafter be sent.

9.4 Parties in Interest. Subject to applicable restrictions contained herein, all covenants and agreements herein contained by or on behalf of the Borrower, the Agent or the Lenders shall be binding upon and inure to the benefit of the Borrower, the Agent or the Lenders, as the case may be, and their respective legal representatives, successors, and assigns.

9.5 Rights of Third Parties. All provisions herein are imposed solely and exclusively for the benefit of the Agent, Lenders and the Borrower. No other Person shall have any right, benefit, priority, or interest hereunder or as a result hereof or have standing to require satisfaction of provisions hereof in accordance with their terms.

9.6 Renewals; Extensions. All provisions of this Agreement relating to the Notes shall apply with equal force and effect to each promissory note hereafter executed which in whole or in part represents a renewal or extension of any part of the Indebtedness of the Borrower under this Agreement, the Notes, or any other Loan Document.

9.7 No Waiver; Rights Cumulative. No course of dealing on the part of the Agent or a Lender, its officers or employees, nor any failure or delay by the Agent or a Lender with respect to exercising any of its rights under any Loan Document shall operate as a waiver thereof. The rights of the Agent or a Lender under the Loan Documents shall be cumulative and the exercise or partial exercise of any such right shall not preclude the exercise of any other right. Neither the making of any Loan nor the issuance of a Letter of Credit shall constitute a waiver of any of the covenants, warranties, or conditions of the Borrower contained herein. In the event the Borrower is unable to satisfy any such covenant, warranty, or condition, neither the making of any Loan nor the issuance of a Letter of Credit shall have the effect of precluding the Agent from thereafter declaring such inability to be an Event of Default as hereinabove provided.

9.8 Survival Upon Unenforceability. In the event any one or more of the provisions contained in any of the Loan Documents or in any other instrument referred to herein or executed in connection with the Obligations shall, for any reason, be held to be invalid, illegal, or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision of any Loan Document or of any other instrument referred to herein or executed in connection with such Obligations.

- 55 -

9.9 Amendments; Waivers. Neither this Agreement nor any provision hereof may be amended, waived, discharged, or terminated orally, but only by an instrument in writing signed by the party against whom enforcement of the amendment, waiver, discharge, or termination is sought.

9.10 Controlling Agreement. In the event of a conflict between the provisions of this Agreement and those of any other Loan Document, the provisions of this Agreement shall control.

9.11 Disposition of Collateral. Notwithstanding any term or provision, express or implied, in any of the Security Instruments, the realization, liquidation, foreclosure, or any other disposition on or of any or all of the Collateral shall be in the order and manner and determined in the sole discretion of the Agent; provided, however, that in no event shall the Agent violate applicable law or exercise rights and remedies other than those provided in such Security Instruments or otherwise existing at law or in equity.

9.12 USA Patriot Act Notice. The Agent hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act the Agent is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow the Agent to identify the Borrower in accordance with the USA Patriot Act.

9.13 Tax Shelter Regulations. The Borrower does not intend to treat the Loans and related transactions hereunder and under the other Loan Documents as a “reportable transaction” (within the meanings under current Treasury Regulation Section 1.6011-4 and Proposed Treasury Regulation Section 1.6011-4, promulgated on November 1, 2006). In the event the Borrower determines to take any action inconsistent with the foregoing statement, it will promptly notify the Agent thereof. If the Borrower so notifies the Agent, the Borrower acknowledges that the Agent and the Lenders may treat the Loans and related transactions hereunder and under the other Loan Documents as part of a transaction that is subject to current Treasury Regulation Section 301.6112-1 or Proposed Treasury Regulation Section 301.6112-1, promulgated on November 1, 2006, and, in such case, the Agent will maintain the lists and other records required, if any, by such Treasury Regulations.

9.14 Governing law. THIS AGREEMENT AND THE NOTES SHALL BE DEEMED TO BE CONTRACTS MADE UNDER AND SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS WITHOUT GIVING EFFECT TO PRINCIPLES THEREOF RELATING TO CONFLICTS OF LAW.
