(a) During the period from the Effective Date to the Termination Date, the Company may, upon irrevocable written notice to the Administrative Agent in accordance with Subsection 2.03(b): (i) elect, as of any Business Day, in the case of Base Rate Loans, or as of the last day of the applicable Interest Period, in the case of LIBOR Loans, to convert any such Loans into Loans of any other Interest Rate Type; or (ii) elect as of the last day of the applicable Interest Period, to continue any Loans having Interest Periods expiring on such day; provided, that if at any time a LIBOR Loan in respect of any Borrowing is reduced, by payment, prepayment, or conversion of part thereof to less than $3,000,000, such LIBOR Loan shall automatically convert into a Base Rate Loan.

(b) The Company shall deliver a Notice of Conversion/Continuation to be received by the Administrative Agent not later than 10:00 a.m. (San Francisco, California time) at least (i) three (3) Business Days in advance of the Conversion/Continuation Date, if the Loans are to be converted into or continued as LIBOR Loans; and (ii) one (1) Business Day in advance of the Conversion/Continuation Date, if the Loans are to be converted into Base Rate Loans, specifying: (A) the proposed Conversion/Continuation Date; (B) the aggregate amount of Loans to be converted or continued; (C) the Interest Rate Type of Loans resulting from the proposed conversion or continuation; and (D) other than in the case of conversions into Base Rate Loans, the duration of the requested Interest Period.

(c) If upon the expiration of any Interest Period applicable to LIBOR Loans, the Company has failed to select timely a new Interest Period to be applicable to LIBOR Loans, or if any Default or Event of Default then exists, the Company shall be deemed to have elected to convert such LIBOR Loans into Base Rate Loans effective as of the expiration date of such Interest Period.

(d) The Administrative Agent will promptly notify each Lender of its receipt of a Notice of Conversion/Continuation, or, if no timely notice is provided by the Company, the Administrative Agent will promptly notify each Lender of the details of any automatic conversion. All conversions and continuations shall be made ratably according to the respective Lender’s Pro Rata Share of outstanding principal amounts of the Loans with respect to which the notice was given.

2.04 Optional Prepayments. Subject to Section 3.04, the Company may, at any time or from time to time,

(a) prepay Base Rate Loans, without premium or penalty, upon irrevocable notice to the Administrative Agent of not less than one (1) Business Day, ratably as to each Lender, in whole or in part, in aggregate minimum principal amounts of $1,000,000 or multiple integrals thereof (unless the outstanding principal amount of all Base Rate Loans is less than $1,000,000, then such prepayments shall be equal to such outstanding principal amount) and

(b) prepay LIBOR Loans, without premium or penalty (but subject to Section 3.04) upon irrevocable notice to the Administrative Agent not less than three (3) Business Days, ratably as to each Lender, prepay Loans, in whole or in part, in aggregate minimum principal amounts of $1,000,000 or multiple integrals thereof plus all interest and expenses then outstanding. Such notice of prepayment shall specify the date and amount of such prepayment and the Interest Rate Type(s) of Loans to be prepaid. The Administrative Agent will promptly notify each Lender of its receipt of any such notice, and of such Lender’s Pro Rata Share of such prepayment. The payment amount specified in such notice shall be due and payable on the date specified therein, together with accrued interest to each such date on the amount prepaid and any amounts required pursuant to Section 3.04.

2.05 Borrowing Base Determinations, Mandatory Prepayments of Loans.

(a) Scheduled Borrowing Base Determinations. At all times prior to the Termination Date the Effective Amount shall not exceed the Borrowing Base then in effect. From and after the Effective Date, the initial Borrowing Base hereunder shall be $90,000,000.00, until redetermined pursuant to the terms of this Section 2.05. Upon notice to the Company, the Borrowing Base shall be redetermined for each Borrowing Base Period on each Scheduled Borrowing Base Determination Date, and each such redetermination shall be effective as of the date set forth in such notice of redetermination. The Borrowing Base shall be determined based upon the loan collateral value assigned to the Oil and Gas Properties owned by the Company and its Subsidiaries and such other credit factors (including without limitation the assets, liabilities, cash flow, business, properties, prospects, management and ownership of the Loan Parties) which the Lenders deem significant. The Lenders’ determination of the Borrowing Base shall be in their sole discretion and shall not be subject to review or challenge under Sections 11.18 and 11.19 hereof. Upon each redetermination of the Borrowing Base, the Administrative Agent shall recommend to the Lenders a new Borrowing Base and the Lenders in accordance with their customary policies and procedures for extending credit to Oil and Gas reserve-based customers shall (by unanimous agreement in the case of Borrowing Base increases and by agreement of the Required Lenders in the case of Borrowing Base decreases or affirmations) establish the redetermined Borrowing Base. If the Company does not furnish the Reserve Reports or all such other information and data by the date required, the Lenders may nonetheless determine a new Borrowing Base. It is expressly understood that the Lenders shall have no obligation to determine the Borrowing Base at any particular amount, either in relation to the Maximum Loan Amount or otherwise.

(b) Special Borrowing Base Determinations. In addition to Scheduled Borrowing Base Determinations pursuant to Subsection 2.05(a), the Company and the Lenders may each request one

(1) additional redetermination of the Borrowing Base during each Borrowing Base Period (“Special Borrowing Base Determination”). In the event the Company requests a Special Borrowing Base Determination pursuant to this Subsection 2.05(b), the Company shall deliver written notice of such request to the Lenders which shall include: (i) Reserve Report(s) prepared as of a date not more than thirty (30) calendar days prior to the date of such request, for the benefit of the Lenders, and (ii) such other information as the Lenders shall request prepared as of a date not more than thirty (30) calendar days prior to the date of such request. Likewise, in the event the Lenders exercise their option for a Special Borrowing Base Determination, the Administrative Agent shall give the Company notice of the redetermined Borrowing Base.

(c) Mandatory Prepayment of Loans. If on any date a Borrowing Base Deficiency shall exist at the time of a Borrowing Base redetermination, then the Company shall, within thirty (30) days notice from Administrative Agent to the Company, exercise any one or combination of the following: (i) make a mandatory principal prepayment in an amount equal to the amount of the Borrowing Base Deficiency, after giving effect to any action taken under (ii) hereof; or (ii) pledge, or cause its Subsidiaries to pledge, additional unencumbered collateral of sufficient value and character (as determined by the Lenders in their sole discretion) that when added to the existing Collateral shall cause the Borrowing Base to equal or exceed the Effective Amount, after giving effect to any action taken under (i) hereof.

2.06 Repayment.

(a) Principal. The Company shall repay to the Administrative Agent (for the Lenders in their respective Pro Rata Shares) the Effective Amount outstanding on the Termination Date on which date all principal amounts outstanding, plus all accrued but unpaid interest and outstanding expenses hereunder or under the Loan Documents, if not sooner paid, shall be due and payable in full.

(b) Interest.

(i) Each Loan shall bear interest on the aggregate outstanding principal amount thereof from the applicable Borrowing Date or date of conversion or continuation pursuant to Section 2.03, as the case may be, at a rate per annum equal to the lesser of (A) the LIBOR or the Base Rate, as the case may be, plus the Applicable Margin, or (B) the Highest Lawful Rate.

(ii) Interest on each Loan shall be paid in arrears on each Interest Payment Date. Interest shall also be paid on the date of any prepayment of Loans under Subsection 2.04(b) or 2.05(c) (except in the case of Base Rate Loans) for the portion of the Loans so prepaid and upon payment (including prepayment) in full thereof and, during the existence of any Event of Default, interest shall be paid on demand of the Administrative Agent.

(iii) Notwithstanding Subsection 2.06(b)(i), while any Event of Default exists, the Company shall pay interest (after, as well as before, entry of judgment thereon, to the extent permitted by law) on the principal amount of all outstanding Loans, at a rate per annum equal to the lesser of (A) the Highest Lawful Rate and (B) the Base Rate plus three percent (3%) (the “Default Rate”).

2.07 Fees.

(a) Commitment Fee. The Company shall pay to the Administrative Agent, for the account of the Lenders, an aggregate commitment fee calculated on the average daily amount of the

Available Borrowing Base at a per annum rate equal to the amount set forth on the Pricing Grid. Such commitment fee shall accrue from the Effective Date to the Termination Date and shall be due and payable quarterly in arrears on the first Business Day of the first month of each quarter commencing on October 1, 2006, through the Termination Date, with the final payment to be made on the Termination Date; provided that, in connection with any reduction or termination of Commitments, the accrued commitment fee calculated for the period ending on such date shall also be paid on the date of such reduction or termination, with the following quarterly payment being calculated on the basis of the period from such reduction or termination date to the following quarterly payment date. The commitment fee provided in this subsection shall accrue at all times after the Effective Date up to the Termination Date, including at any time during which one or more conditions in Section 5.02 are not met.

(b) Letter of Credit Fee. The Company agrees to pay (i) to Issuing Lender (for the ratable account of the Lenders in their respective Pro Rata Shares), a fee for each Letter of Credit, to be paid quarterly in arrears following the Issuance of such Letter of Credit (including the initial Issuance and any renewal, extension or increase in the amount thereof) in the amount equal to the greater of (A) $500.00 and (B) the product equal to the Letter of Credit rate set forth on the Pricing Grid multiplied by the undrawn amount available under such Letter of Credit (such fee shall be deemed to be fully earned and owing upon the Issuance of such Letter of Credit, and no refund shall be due in the event such Letter of Credit is terminated prior to its expiry date), and (ii) to the Issuing Lender for its account a fee for the issuance of each Letter of Credit (including the initial Issuance and any renewal, extension or increase in the amount thereof), at the Issuance of such Letter of Credit, in an amount equal to the greater of (A) $500.00 and (B) one-eighth of one percent (0.125%) multiplied by the aggregate amount available under each Letter of Credit (such fees shall be prorated for any period less than a full year but shall not be refunded in the event any such Letter of Credit is terminated prior to its expiry date) and (iii) Issuing Lender’s usual and customary fees for amendment to transfer of or negotiation of the terms of each Letter of Credit. The Administrative Agent shall pay to each Lender its Pro Rata Share of the Letter of Credit Fee paid pursuant to Subsection 2.07(b)(i). The Administrative Agent shall pay to the Issuing Lender the Letter of Credit fees paid pursuant to Subsection 2.07(b)(ii) and (iii).

(c) Agency Fees. The Company shall pay fees to the Administrative Agent for the Administrative Agent’s own account, as required by that certain letter agreement (“Fee Letter”) between the Company and the Administrative Agent dated as of June 12, 2006, relating hereto.

2.08 Computation of Fees and Interest.

(a) All computations of interest for Base Rate Loans shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees and interest shall be made on the basis of a 360-day year and actual days elapsed (which results in more interest being paid than if computed on the basis of a 365-day year). Interest and fees shall accrue during each period during which interest or such fees are computed from the first day thereof to the last day thereof.

(b) Each determination of an interest rate by the Administrative Agent shall be conclusive and binding on the Company and the Lenders in the absence of manifest error.

2.09 Payments by the Company; Borrowings Pro Rata.

(a) All payments to be made by the Company shall be made without set-off, recoupment or counterclaim. All payments by the Company shall be made in immediately available funds to the Administrative Agent by credit to the Company’s operating account at the Administrative Agent’s

Payment Office for the account of the Administrative Agent or the Lender to whom such payment is owed, and shall be made in dollars and in immediately available funds, no later than 10:00 a.m. (San Francisco, California time) on the date specified herein. Except to the extent otherwise provided herein, (i) each payment by the Company of fees shall be made pro rata in accordance with their respective Pro Rata Shares, (ii) each payment of principal of Loans shall be made for the account of the Lenders pro rata in accordance with their respective outstanding principal amount of Loans, and (iii) each payment of interest on Loans shall be made for the account of the Lenders pro rata in accordance with their respective shares of the aggregate amount of interest due and payable to the Lenders. Notwithstanding the foregoing, to the extent money is received by the Administrative Agent pursuant to the exercise of remedies under the Security Documents such money shall be applied to the pro rata payment of obligations secured by such Security Document.

(b) The Administrative Agent will promptly distribute to each Lender its applicable share of such payment in like funds as received. Any payment received by the Administrative Agent later than 10:00 a.m. (San Francisco, California time) shall be deemed to have been received on the following Business Day and any applicable interest or fee shall continue to accrue. When the Administrative Agent collects or receives money on account of the Obligations or otherwise pursuant to the Security Documents if such money is insufficient to pay all such Obligations, such money shall be applied first to any reimbursements due Administrative Agent under Section 11.05 or 11.06.

(c) Subject to the provisions set forth in the definition of “Interest Period” herein, whenever any payment is due on a day other than a Business Day, such payment shall be made on the following Business Day, and such extension of time shall in such case be included in the computation of interest or fees, as the case may be.

(d) Unless the Administrative Agent receives notice from the Company prior to the date on which any payment is due to the Lenders that the Company will not make such payment in full as and when required, the Administrative Agent may assume that the Company has made such payment in full to the Administrative Agent on such date in immediately available funds and the Administrative Agent may (but shall not be so required), in reliance upon such assumption, distribute to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Company has not made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent on demand such amount distributed to such Lender, together with interest thereon for each day from the date such amount is distributed to such Lender until two days following demand by the Administrative Agent and for each day thereafter until the date repaid at the Base Rate.

(e) Except to the extent otherwise expressly provided herein, each borrowing hereunder shall be from the Lenders pro rata in accordance with their respective Pro Rata Shares.

2.10 Issuing the Letters of Credit.

(a) Subject to the terms and conditions set forth herein, the Company may request the Issuing Lender to issue Letters of Credit for its own account or for any of its Subsidiaries, in a form reasonably acceptable to the Administrative Agent and the Issuing Lender, at any time and from time to time during the Availability Period; provided that the Company may not request the issuance, amendment, renewal or extension of Letters of Credit hereunder if the Effective Amount exceeds the Borrowing Base at such time or would exceed the Borrowing Base as a result thereof.

(b) In order to effect the issuance of a Letter of Credit, the Company shall submit a Notice of Borrowing and a LC Application in writing by telecopy to the Administrative Agent (who shall

promptly notify the Issuing Lender) not later than 1:00 p.m., Houston, Texas time, three (3) Business Days before the requested date of issuance of such Letter of Credit. Each such Notice of Borrowing and LC Application shall be (i) signed by the Company, (ii) specify the Business Day on which such Letter of Credit is to be issued, (iii) specify the purpose for the requested Letter of Credit, (iv) specify the availability for Letters of Credit under (A) the Borrowing Base and (B) the $5,000,000 aggregate LC Obligation limitation, as of the date of issuance of such Letter of Credit, and (v) specify the expiry date thereof, which shall not be later than the earlier of (A) twelve (12) months from the date of issuance of such Letter of Credit and (B) seven (7) Business Days prior to the Termination Date.

(c) Upon satisfaction of the applicable terms and conditions set forth in Article V, the Issuing Lender shall issue such Letter of Credit to the specified beneficiary not later than the close of business, Houston, Texas time, on the date so specified. The Administrative Agent shall provide the Company and each Lender with a copy of each Letter of Credit so issued. Each such Letter of Credit shall (i) provide for the payment of drafts, presented for honor thereunder by the beneficiary in accordance with the terms thereon, at sight when accompanied by the documents described therein and (ii) unless otherwise expressly agreed by the Issuing Lender and the Company at the time such Letter of Credit is issued, be subject to the rules of the “International Standby Practices 1998” or such later version as may be published by the Institute of International Banking Law and Practice (the “ISP 1998”), or any successor entity, and shall, as to matters not governed by the ISP 1998, be governed by, and construed and interpreted in accordance with, the laws of the State of Texas.

(d) Upon the issuance date of each Letter of Credit, the Issuing Lender shall be deemed, without further action by any party hereto, to have sold to each other Lender, and each other Lender shall be deemed, without further action by any party hereto, to have purchased from the Issuing Lender, a participation, to the extent of such Lender’s Pro Rata Share, in such Letter of Credit, the obligations thereunder and in the reimbursement obligations of the Company due in respect of drawings made under such Letter of Credit. If requested by the Issuing Lender, the other Lenders will execute any other documents reasonably requested by the Issuing Lender to evidence the purchase of such participation.

(e) Upon the presentment of any draft for honor under any Letter of Credit by the beneficiary thereof which the Issuing Lender determines is in compliance with the conditions for payment thereunder, the Issuing Lender shall promptly notify the Company, the Administrative Agent and each Lender of the intended date of honor of such draft and the Company hereby promises and agrees, at the Company’s option, to either (i) pay to the Administrative Agent for the account of the Issuing Lender, by 2:00 p.m., Houston, Texas time, on the date payment is due as specified in such notice, the full amount of such draft in immediately available funds or (ii) request a Loan pursuant to the provisions of Subsection 2.01(a) and Section 2.02 of this Agreement in the full amount of such draft, which request shall specify that the Borrowing Date is to be the date payment is due under the Letter of Credit as specified in the Issuing Lender’s notice. If the Company fails timely to make such payment because a Loan cannot be made pursuant to Subsection 2.01(a) and/or Section 5.02, each Lender shall, notwithstanding any other provision of this Agreement (including the occurrence and continuance of a Default or an Event of Default), make available to the Administrative Agent for the benefit of the Issuing Lender an amount equal to its Pro Rata Share of the presented draft on the day the Issuing Lender is required to honor such draft. If such amount is not in fact made available to the Administrative Agent by such Lender on such date, such Lender shall pay to the Administrative Agent for the account of the Issuing Lender, on demand made by the Issuing Lender, in addition to such amount, interest thereon at the Federal Funds Rate for the first two days following demand and thereafter until paid at the Base Rate. Upon receipt by the Administrative Agent from the Lenders of the full amount of such draft, notwithstanding any other provision of this Agreement (including the occurrence and continuance of a Default or an Event of

Default) the full amount of such draft shall automatically and without any action by the Company, be deemed to have been a Base Rate Loan as of the date of payment of such draft. Nothing in this Subsection 2.05(d) or elsewhere in this Agreement shall diminish the Company’s obligation under this Agreement to provide the funds for the payment of, or on demand to reimburse the Issuing Lender for payment of, any draft presented to, and duly honored by, the Issuing Lender under any Letter of Credit, and the automatic funding of a Loan as in this paragraph provided shall not constitute a cure or waiver of the Event of Default for failure to provide timely such funds as in this paragraph agreed.

(f) In order to induce the issuance of Letters of Credit by the Issuing Lender and the purchase of participations therein by the other Lenders, the Company agrees with Administrative Agent, Issuing Lender and the other Lenders that neither Administrative Agent nor any Lender (including Issuing Lender) shall be responsible or liable (except as provided in the following sentence) for amounts paid by Issuing Lender, as provided in Subsection 2.10(e), on account of drafts so honored under the Letters of Credit, and the Company’s unconditional obligation to reimburse the Issuing Lender through the Administrative Agent for such amounts shall not be affected by, any circumstance, act or omission whatsoever (whether or not known to the Administrative Agent or any Lender (including the Issuing Lender) other than a circumstance, act or omission resulting from the gross negligence or willful misconduct of the Administrative Agent or any Lender, including the Issuing Lender. The Company agrees that any action taken or omitted to be taken by the Administrative Agent or any Lender (including the Issuing Lender) under or in connection with any Letter of Credit or any related draft, document or Property shall be binding on the Company and shall not put the Administrative Agent or any Lender (including the Issuing Lender) under any resulting liability to the Company, unless such action or omission is the result of the gross negligence or willful misconduct of the Administrative Agent or any such Lender (including the Issuing Lender). The Company hereby waives presentment for payment (except the presentment required by the terms of any Letter of Credit) and notice of dishonor, protest and notice of protest with respect to drafts honored under the Letters of Credit. The Issuing Lender agrees promptly to notify the Company whenever a draft is presented under any Letter of Credit, but failure to so notify the Company shall not in any way affect the Company’s obligations hereunder. Subject to Section 3.07, if while any Letter of Credit is outstanding, any law, executive order or regulation is enforced, adopted or interpreted by any public body, governmental agency or court of competent jurisdiction so as to affect any of the Company’s obligations or the compensation to any Lender in respect of the Letters of Credit or the cost to such Lender of establishing and/or maintaining the Letters of Credit (or any participation therein), such Lender shall promptly notify the Company thereof in writing and within ten (10) Business Days after receipt by the Company of such Lender’s request (through the Administrative Agent) for reimbursement or indemnification or within thirty (30) days after receipt of a notice in respect of Taxes or Other Taxes, the Company shall reimburse or indemnify such Lender, as the case may be, with respect thereto so that such Lender shall be in the same position as if there had been no such enforcement, adoption or interpretation, unless the Company notifies the Administrative Agent of its good faith contest to, and dispute of, the requested amount. The foregoing agreement of the Company to reimburse or indemnify the Lenders shall apply in (but shall not be limited to) the following situations: an imposition of or change in reserve, capital maintenance or other similar requirements or in excise or similar taxes or monetary restraints, except a change in franchise taxes imposed on such Lender or in tax on the net income of such Lender.

(g) In the event that any provision of a LC Application is inconsistent with, or in conflict of, any provision of this Agreement, including provisions for the rate of interest applicable to drawings thereunder or rights of setoff or any representations, warranties, covenants or any events of default set forth therein, the provisions of this Agreement shall govern.

(h) If the Obligations, or any part thereof, are declared or otherwise become immediately due and payable pursuant to Article IX of this Agreement (for the purposes of this paragraph, the “Matured Obligations”), then all LC Obligations shall become immediately due and payable without regard for actual drawings or payments on the Letters of Credit, and the Company shall be obligated to pay to the Administrative Agent immediately an amount equal to the LC Obligations. All amounts made due and payable by the Company under this Subsection 2.10(h) may be applied as the Issuing Lender and the Lenders elect to any of the various LC Obligations; provided, however, that such amounts applied by the Issuing Lender and the Lenders to the LC Obligations shall be (i) first applied to the Matured LC Obligations, and (ii) second held by the Administrative Agent for the benefit of the Issuing Lender and the Lenders as LC Collateral in the LC Collateral Account until all remaining Matured Obligations have been satisfied. This Subsection 2.10(h) shall not limit or impair any rights which the Administrative Agent, the Issuing Lender or any of the Lenders may have under any other document or agreement relating to any Letter of Credit or LC Obligation, including without limitation, any LC Application. The Company hereby grants a security interest in and lien on the LC Collateral Account to the Administrative Agent for and on behalf of the Lenders as security for the Obligations. The Company agrees to execute and deliver from time to time such documentation as the Administrative Agent may reasonably request to further assure such security interest.

2.11 Payments by the Lenders to the Administrative Agent.

(a) Unless the Administrative Agent receives notice from a Lender on or prior to the Effective Date or, with respect to any Borrowing after the Effective Date, at least one (1) Business Day prior to the date of such Borrowing, that such Lender will not make available as and when required hereunder to the Administrative Agent for the account of the Company the amount of that Lender’s Pro Rata Share of the Borrowing, the Administrative Agent may assume that each Lender has made such amount available to the Administrative Agent in immediately available funds on the Borrowing Date and the Administrative Agent may (but shall not be so required), in reliance upon such assumption, make available to the Company on such date a corresponding amount. If and to the extent any Lender shall not have made its full amount available to the Administrative Agent in immediately available funds and the Administrative Agent in such circumstances has made available to the Company such amount, that Lender shall on the Business Day following such Borrowing Date make such amount available to the Administrative Agent, together with interest at the Federal Funds Rate for the first two days during such period and thereafter at the Base Rate. A notice of the Administrative Agent submitted to any Lender with respect to amounts owing under this Subsection 2.11(a) shall be conclusive, absent manifest error. If such amount is so made available, such payment to the Administrative Agent shall constitute such Lender’s Loan on the date of Borrowing for all purposes of this Agreement. If such amount is not made available to the Administrative Agent on the Business Day following the Borrowing Date, the Administrative Agent will notify the Company of such failure to fund and, upon demand by the Administrative Agent, the Company shall pay such amount to the Administrative Agent for the Administrative Agent’s account, together with interest thereon for each day elapsed since the date of such Borrowing, at a rate per annum equal to the interest rate applicable at the time to the Loans comprising such Borrowing.

(b) The failure of any Lender to make any Loan on any Borrowing Date shall not relieve any other Lender of any obligation hereunder to make a Loan on such Borrowing Date, but no Lender shall be responsible for the failure of any other Lender to make the Loan to be made by such other Lender on any Borrowing Date.

2.12 Sharing of Payments, Etc. If any Lender shall obtain on account of the Obligations made by it any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or

otherwise) or receive any collateral in respect thereof in excess of the amount such Lender was entitled to receive pursuant to the terms hereof, such Lender shall immediately (a) notify the Administrative Agent of such fact, and (b) purchase from the other Lenders such participations in the Loans made by them as shall be necessary to cause such purchasing Lender to share the excess payment according to the terms hereof; provided, however, that if all or any portion of such excess payment is thereafter recovered from the purchasing Lender, such purchase shall to that extent be rescinded and each other Lender shall repay to the purchasing Lender the purchase price paid therefor, together with an amount equal to such paying Lender’s ratable share (according to the proportion of (i) the amount of such paying Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Company agrees that any Lender so purchasing a participation from another Lender may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off, but subject to Section 11.09) with respect to such participation as fully as if such Lender were the direct creditor of the Company in the amount of such participation. The Administrative Agent will keep records (which shall be conclusive and binding in the absence of manifest error) of participations purchased under this Section and will in each case notify the Lenders following any such purchases or repayments.

ARTICLE III.

TAXES, YIELD PROTECTION AND ILLEGALITY

3.01 Taxes.

(a) Any and all payments by the Company to each Lender or the Administrative Agent under this Agreement and any other Loan Document shall be made free and clear of, and without deduction or withholding for any Taxes. In addition, the Company shall pay all Other Taxes.

(b) The Company agrees to indemnify and hold harmless each Lender and the Administrative Agent for the full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section) paid by the Lender or the Administrative Agent and any liability (including penalties, interest, additions to tax and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. Payment under this indemnification shall be made within thirty (30) days after the date the Lender or the Administrative Agent makes written demand therefor.

(c) If the Company shall be required by law to deduct or withhold any Taxes or Other Taxes from or in respect of any sum payable hereunder to any Lender or the Administrative Agent, then: (i) the sum payable shall be increased as necessary so that after making all required deductions and withholdings (including deductions and withholdings applicable to additional sums payable under this Section) such Lender or the Administrative Agent, as the case may be, receives an amount equal to the sum it would have received had no such deductions or withholdings been made; (ii) the Company shall make such deductions and withholdings; and (iii) the Company shall pay the full amount deducted or withheld to the relevant taxing authority or other authority in accordance with applicable law.

(d) Upon request of the Administrative Agent, the Company shall furnish the Administrative Agent the original or a certified copy of a receipt evidencing payment by the Company of Taxes or Other Taxes under Subsection 3.01(c), or other evidence of payment satisfactory to the Administrative Agent.

(e) If the Company is required to pay additional amounts to any Lender or the Administrative Agent pursuant to this Section 3.01, then upon written request of the Company such Lender shall use reasonable efforts (consistent with legal and regulatory restrictions) to change the jurisdiction of its Lending Office and take such other steps, in each case, so as to eliminate any such additional payment by the Company which may thereafter accrue, if such change or step, as applicable, in the judgment of such Lender is not otherwise disadvantageous to such Lender.

(f) If the Company pays any additional amounts under this Section 3.01 to a Lender and such Lender determines that it has actually received or realized in connection therewith any refund or reduction of, or credit against, its tax liability in or with respect to the taxable year in which the additional amount is paid (a “Tax Benefit”), such Lender shall pay to the Company an amount that such Lender shall determine is equal to the net benefit after tax, which was obtained by such Lender in such year as a consequences of such Tax Benefit. If the Company determines in good faith that a reasonable basis exists for contesting any Taxes or Other Taxes with respect to which the Company has paid any additional amounts under this Section 3.01 or for which indemnification has been demanded hereunder, the relevant Lender or Administrative Agent, as applicable, may, in its discretion, not to be unreasonably withheld, cooperate with the Company in challenging such Taxes or Other Taxes at the Company’s expense if so requested by the Company in writing.

3.02 Illegality.

(a) If any Lender determines that the introduction of any Requirement of Law, or any change in any Requirement of Law, or in the interpretation or administration of any Requirement of Law, has, since the Effective Date, made it unlawful, or that, since the Effective Date, any central bank or other Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make LIBOR Loans, then, on notice thereof by the Lender to the Company through the Administrative Agent, any obligation of that Lender to make LIBOR Loans shall be suspended until the Lender notifies the Administrative Agent and the Company that the circumstances giving rise to such determination no longer exist; such notice to be promptly given upon the determination that such circumstances no longer exist.

(b) If a Lender determines that it is unlawful to maintain any LIBOR Loan, the Company shall, upon its receipt of notice of such fact and demand from such Lender (with a copy to the Administrative Agent), convert such LIBOR Loans of that Lender then outstanding, together with interest accrued thereon and amounts required under Section 3.04 into a Base Rate Loan without regard to conditions precedent described in Subsection 5.02(b), either on the last day of the Interest Period thereof, if the Lender may lawfully continue to maintain such LIBOR Loans to such day, or immediately, if the Lender may not lawfully continue to maintain such LIBOR Loan. If the Company is required to so prepay any LIBOR Loan, then concurrently with such prepayment, the Company shall borrow from the affected Lender, in the amount of such repayment, a Base Rate Loan.

(c) If the obligation of any Lender to make or maintain LIBOR Loans has been so terminated or suspended, all Loans which would otherwise be made by the Lender as LIBOR Loans shall be instead Base Rate Loans.

(d) Before giving any notice to the Administrative Agent under this Section, the affected Lender shall designate a different Lending Office with respect to its LIBOR Loans if such designation will avoid the need for giving such notice or making such demand and will not, in the judgment of the Lender, be illegal or otherwise disadvantageous to the Lender.

3.03 Increased Costs and Reduction of Return.

(a) If any Lender determines, after the Effective Date, that, due to either (i) the introduction of or any change (other than any change by way of imposition of or increase in reserve requirements included in the calculation of the LIBOR) in or in the interpretation of any law or regulation or (ii) the compliance by that Lender with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), there shall be any increase in the cost to such Lender of agreeing to make or making, funding or maintaining any LIBOR Loans, (except for any such increased cost resulting from taxes of any kind, including Taxes and Other Taxes, as to which Section 3.01 shall govern) then the Company shall be liable for, and shall from time to time, upon demand (with a copy of such demand to be sent to the Administrative Agent), pay to the Administrative Agent for the account of such Lender, additional amounts as are sufficient to compensate such Lender for such increased costs.

(b) If any Lender shall have determined, after the Effective Date, that (i) the introduction of any Capital Adequacy Regulation, (ii) any change in any Capital Adequacy Regulation, (iii) any change in the interpretation or administration of any Capital Adequacy Regulation by any central bank or other Governmental Authority charged with the interpretation or administration thereof, or (iv) compliance by the Lender (or its Lending Office) or any corporation controlling the Lender with any Capital Adequacy Regulation, affects or would affect the amount of capital required or expected to be maintained by the Lender or any corporation controlling the Lender and (taking into consideration such Lender’s or such corporation’s policies with respect to capital adequacy and such Lender’s desired return on capital) determines that the amount of such capital is increased as a consequence of its Commitments, loans, credits or obligations under this Agreement, then, upon demand of such Lender to the Company through the Administrative Agent, the Company shall pay to the Lender, from time to time as specified by the Lender, additional amounts sufficient to compensate the Lender for such increase.

3.04 Funding Losses. The Company shall reimburse each Lender and hold each Lender harmless from any loss or expense excluding consequential losses which the Lender may sustain or incur as a consequence of: (a) the failure of the Company to make on a timely basis any payment of principal of any LIBOR Loan; (b) the failure of the Company to borrow, continue or convert a Loan after the Company has given (or is deemed to have given) a Notice of Borrowing or a Notice of Conversion/Continuation (including by reason of the failure to satisfy any condition precedent thereto); (c) the failure of the Company to make any prepayment in accordance with any notice delivered under Section 2.04; (d) the prepayment (including pursuant to Section 2.05 or 2.06) or other payment (including after acceleration thereof) of an LIBOR Loan on a day that is not the last day of the relevant Interest Period; or (e) the automatic conversion under Section 2.03 of any LIBOR Loan to a Base Rate Loan on a day that is not the last day of the relevant Interest Period; including any such loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain its LIBOR Loans or from fees payable to terminate the deposits from which such funds were obtained. For purposes of calculating amounts payable by the Company to the Lenders under this Section and under Subsection 3.03(a), each LIBOR Loan made by a Lender (and each related reserve, special deposit or similar requirement) shall be conclusively deemed to have been funded at the LIBOR used in determining the LIBOR for such LIBOR Loan by a matching deposit or other borrowing in the interbank eurodollar market for a comparable amount and for a comparable period, whether or not such LIBOR Loan is in fact so funded.

3.05 Inability to Determine Rates. If Administrative Agent determines that for any reason adequate and reasonable means do not exist for determining the LIBOR for any requested Interest Period with respect to a proposed LIBOR Loan, or that the LIBOR applicable pursuant to Subsection 2.06(b) for any requested Interest Period with respect to a proposed LIBOR Loan does not adequately and fairly

reflect the cost to the Lender of funding such Loan, the Administrative Agent will promptly so notify the Company and each Lender. Thereafter, the obligation of the Lenders to make or maintain LIBOR Loans hereunder shall be suspended until the Administrative Agent upon the instruction of the Lenders revokes such notice in writing; such written revocation to be promptly given up determination that such circumstances no longer exist. Upon receipt of such notice, the Company may revoke any Notice of Borrowing or Notice of Conversion/Continuation then submitted by it. If the Company does not revoke such Notice, the Lenders shall make, convert or continue the Loans, as proposed by the Company, in the amount specified in the applicable notice submitted by the Company, but such Loans shall be made, converted or continued as Base Rate Loans instead of LIBOR Loans.

3.06 Certificates of Lenders. Any Lender claiming reimbursement or compensation under this Article III shall deliver to the Company (with a copy to the Administrative Agent) a certificate setting forth in reasonable detail the amount payable to the Lender hereunder and such certificate shall be conclusive and binding on the Company in the absence of manifest error provided, however, that such Lender shall only be entitled to collect amounts incurred within 180 days of such notice.

3.07 Substitution of Lenders. Upon the receipt by the Company from any Lender (an “Affected Lender”) of a claim for compensation under this Article III, the Company may: (a) obtain a replacement Lender or financial institution satisfactory to the Administrative Agent (a “Replacement Lender”) to acquire and assume all or a ratable part of all of such Affected Lender’s Loans and Commitment; or (b) request one more of the other Lenders to acquire and assume all or part of such Affected Lender’s Loans and Commitment but none of the Lenders shall have any obligation to do so. Any such designation of a Replacement Lender under (a) shall be subject to the prior written consent of the Administrative Agent which consent shall not be unreasonably withheld or delayed.

3.08 Survival. The agreements and obligations of the Company in this Article III shall survive the payment of all other Obligations.

4.04 Offset. To secure the repayment of the Obligations the Company hereby grants the Administrative Agent and each Lender a security interest, a lien, and a right of offset, each of which shall be in addition to all other interests, liens, and rights of the Administrative Agent at common law, under the Loan Documents, or otherwise, and each of which shall be upon and against (a) any and all moneys, securities or other property (and the proceeds therefrom) of the Company now or hereafter held or received by or in transit to the Administrative Agent or any Lender from or for the account of the Company, whether for safekeeping, custody, pledge, transmission, collection or otherwise, (b) any and all deposits (general or special, time or demand, provisional or final) of the Company with the Administrative Agent or any Lender, and (c) any other credits and claims of the Company at any time existing against the Administrative Agent or any Lender, including claims under certificates of deposit.

The board of directors, managers or general partner, where applicable, of each Guarantor has determined that such Guarantor’s execution, delivery and performance of this Agreement may reasonably be expected to directly or indirectly benefit such Guarantor and is in the best interests of such Guarantor.

(c) The direct or indirect value of the consideration received and to be received by such Guarantor in connection herewith is reasonably worth at least as much as the liability and obligations

offset by a corresponding proportionate increase in such Loan Party’s net revenue interest in such Property. No consents or rights of first refusal exist or remain outstanding with respect to such Loan Party’s interest in the Mortgaged Properties assigned to it pursuant to any Acquisition of Oil and Gas Properties other than Permitted Liens. As of the Effective Date, the property of the Loan Parties is subject to no Liens, other than Permitted Liens.

7.06 Title Information.

(a) On or before the delivery to the Administrative Agent and the Lenders of each Reserve Report required by Subsection 7.02(e), the Company 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 80% of the total net present value (determined by a discount factor of 10%) of the proved Oil and Gas Properties evaluated by such Reserve Report.

Administrative Agent or the Lenders. To the extent that the Administrative Agent or the Majority Lenders are not reasonably satisfied with title to any Mortgaged Property after the 60-day period has elapsed, such unacceptable Mortgaged Property shall not count towards “the 80% requirement”, and the Administrative Agent may send a notice to the Company and the Lenders that the then outstanding Borrowing Base shall be reduced by an amount as determined by the Majority Lenders to cause the Company to be in compliance with the requirement to provide acceptable title information on 80% of the net present value (determined by a discount factor of 10%) of the Oil and Gas Properties.

10.02 Duties and Obligations of Administrative Agent. The Administrative Agent shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing (the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law; rather, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties), (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except as provided in Section 10.03, and (c) except as expressly set forth herein, the Administrative Agent shall have no duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Company or any of its Subsidiaries that is communicated to or obtained by the

Lender serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Company 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 V or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent or as to those conditions precedent expressly required to be to the Administrative Agent’s satisfaction, (vi) the existence, value, perfection or priority of any collateral security or the financial or other condition of the Loan Parties or any other obligor or guarantor, or (vii) any failure by the Company 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.

The Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing as directed by the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 2.05) and in all cases the Administrative Agent shall be fully justified in failing or refusing to act hereunder or under any other Loan Documents unless it shall (i) receive written instructions from the Majority Lenders or the Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02) specifying the action to be taken and (ii) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of taking or continuing to take any such action. The instructions as aforesaid and any action taken or failure to act pursuant thereto by the Administrative Agent shall be binding on all of the Lenders. If a Default has occurred and is continuing, then the Administrative Agent shall take such action with respect to such Default as shall be directed by the Majority Lenders in the written instructions (with indemnities) described in this Section 10.03, provided that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interests of the Lenders. In no event, however, shall the Administrative Agent be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, the Loan Documents or applicable law. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Majority Lenders or the Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 2.05), and otherwise the Administrative Agent shall not be liable for any action taken or not taken by it hereunder or under any other Loan Document or under any other document or instrument referred to or 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.

10.04 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person.

Administrative Agent’s record of such statement, except in the case of gross negligence or willful misconduct by the Administrative Agent. The Administrative Agent may consult with legal counsel (who may be counsel for the Company), 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.

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

10.06 Administrative Agent as Lender. Administrative Agent 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 Administrative Agent, and it and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Company or any Subsidiary or other Affiliate thereof as if it were not Administrative Agent hereunder.

10.07 No Reliance. Each Lender acknowledges that it has, independently and without reliance upon the Administrative 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 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 Company 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 Company 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, the Administrative Agent shall have no duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of the Company (or any of its Affiliates) which may come into the possession of the Administrative Agent or any of its Affiliates. In this regard, each Lender acknowledges that ▇▇▇▇▇▇ and ▇▇▇▇▇, L.L.P. is acting in this transaction as special counsel to the Administrative Agent only, except to the extent otherwise expressly stated in any legal opinion or any Loan Document. Each other party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein.

10.08 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any of its Subsidiaries, the Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any

demand on the Company) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other Indebtedness that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under Section 11.04) allowed in such judicial proceeding; and

(b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Section 11.04.

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

10.09 Authority of Administrative Agent to Release Collateral and Liens. Each Lender and Issuing Lender hereby authorizes the Administrative Agent to release any collateral that is permitted to be sold or released pursuant to the terms of the Loan Documents. Each Lender and Issuing Lender hereby authorizes the Administrative Agent to execute and deliver to the Company, at the Company’s sole cost and expense, any and all releases of Liens, termination statements, assignments, or other documents reasonably requested by the Company 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 8.02 or is otherwise authorized by the terms of the Loan Documents.

10.10 The Arrangers, the Syndication Agent and the Documentation Agent. The Lead Arranger, the Syndication Agent and the Documentation Agent shall have no duties, responsibilities or liabilities under this Agreement and the other Loan Documents other than their duties, responsibilities and liabilities in their capacity as Lenders hereunder.

10.11 Successor Administrative Agent. The Administrative Agent may resign as the Administrative Agent upon 30 days’ notice to the Lenders. If the Administrative Agent resigns under this Agreement, the Majority Lenders shall appoint from among the Lenders a successor administrative agent reasonably satisfactory to the Company in the same capacity as the retiring Administrative Agent for the Lenders. If no successor administrative agent is appointed prior to the effective date of the resignation of such retiring Administrative Agent, such retiring Administrative Agent may appoint, after consulting with the Lenders, a successor administrative agent from among the Lenders. Upon the acceptance of its appointment as successor administrative agent hereunder, such successor administrative agent shall succeed to all the rights, powers and duties of the retiring Administrative Agent and the term “Administrative Agent” shall mean such successor administrative agent and the retiring Administrative Agent’s appointment, powers and duties as the Administrative Agent shall be terminated. After any

retiring Administrative Agent’s resignation hereunder as the Administrative Agent, the provisions of this Article X and Sections 11.04 and 11.05 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Administrative Agent under this Agreement. If no successor administrative agent has accepted appointment as the Administrative Agent in the same capacity as the retiring Administrative Agent by the date which is 30 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent shall either withdraw its resignation or may appoint as a successor administrative agent a commercial Lender organized under the laws of the United States of America or of any State thereof having a commercial capital surplus of at least $500,000,000.

10.12 Withholding Tax.

(a) If any Lender is a not a “United States person” within the meaning of Section 7701(a)(3) of the Code (a “Foreign Lender”), such Foreign Lender agrees with and in favor of the Administrative Agent, to deliver to the Administrative Agent prior to receipt of any payment subject to withholding under the Code (or upon accepting an assignment or participation of an interest herein), two duly signed completed copies of either IRS Form W-8BEN or any successor thereto (relating to such Foreign Lender and entitling it to a complete exemption from withholding tax on all payments to be made to such Foreign Lender by the Company pursuant to this Agreement) or IRS Form W-8ECI or any successor thereto (relating to all payments to be made to such Foreign Lender by the Company pursuant to this Agreement) or such other evidence satisfactory to the Company that such Foreign Lender is entitled to a complete exemption from U.S. withholding tax, including any exemption pursuant to Section 881(c) of the Code. Thereafter and from time to time, each such Foreign Lender shall (i) promptly submit to the Company such additional duly completed and signed copies of one of such forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may then be available under then current United States laws and regulations to avoid, or such evidence as is satisfactory to the Company of any available complete exemption from United States withholding taxes in respect of all payments to be made to such Foreign Lender by the Company pursuant to this Agreement, and (ii) promptly notify the Administrative Agent and the Company of any change in circumstances which would modify or render invalid any claimed exemption.

(b) Each Foreign Lender, to the extent it does not act or ceases to act for its own account with respect to any portion of any sums paid or payable to that Lender under any of the Loan Documents (for example, in the case of a typical participation by that Lender), shall deliver to the Administrative Agent on the date when such Foreign Lender ceases to act for its own account with respect to any portion of any such sums paid or payable, and at such other times as may be necessary in the determination of the Administrative Agent (in the reasonable exercise of its discretion), (i) two duly signed completed copies of the forms or statements required to be provided by that Lender as set forth above, to establish the portion of any such sums paid or payable with respect to which that Lender acts for its own account that is not subject to U.S. withholding tax, and (ii) two duly signed completed copies of IRS Form W-8IMY (or any successor thereto), together with any information that is required by the Code and Treasury regulations promulgated thereunder and any additional information that Lender chooses to transmit with such form, and any other certificate or statement of exemption required under the Code, to establish that that Lender is not acting for its own account with respect to a portion of any such sums payable to that Lender.

(c) The Company shall not be required to pay any additional amount to any Foreign Lender under Section 3.01: (i) with respect to any Taxes or Other Taxes required to be deducted or withheld on the basis of the information, certificates or statements of exemption that Foreign Lender transmits with an IRS Form W-8IMY pursuant to Subsection 10.12(b) or (ii) if that Foreign Lender shall have failed to satisfy the foregoing provisions of this Section 10.12.

(d) Each Lender that is a “United States person” within the meaning of Section 7701(a)(30) of the Code (“Domestic Lender”) shall deliver to the Administrative Agent two duly signed completed copies of IRS Form W-9. If that Domestic Lender fails to deliver such forms, then the Company may withhold from any interest payment to that Domestic Lender an amount equivalent to the applicable back-up withholding tax imposed by the Code, without reduction. Thereafter and from time to time, each such Domestic Lender shall (i) promptly submit to the Company such additional duly completed and signed copies of one of such forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may then be available under then current United States laws and regulations to avoid, or such evidence as is satisfactory to the Company of any available exemption from United States withholding taxes in respect of all payments to be made to such Domestic Lender by the Company pursuant to this Agreement, and (ii) promptly notify the Company of any change in circumstances which would modify or render invalid any claimed exemption.

(e) No Assignee shall be entitled to the benefits of Section 3.01 unless the Company is notified of the assignment and such Assignee has complied with the requirements of this Section 10.12.

(f) If any Lender is entitled to a reduction in the applicable withholding tax, the Administrative Agent may withhold from any payment to such Lender an amount equivalent to the applicable withholding tax after taking into account such reduction. If (i) a Lender does not deliver the forms or other documentation required this Section 10.12 to the Administrative Agent, or (ii) the Company is required by law to deduct and withhold from or in respect of any amounts payable under any Loan Document to a Lender but is not required to pay additional amounts under Section 3.01 with respect to such payment, then the Administrative Agent may deduct from any payment to such Lender an amount equivalent to the applicable withholding tax.

(g) If the IRS or any other Governmental Authority of the United States or other jurisdiction asserts a claim that the Administrative Agent did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered, was not properly executed, or because such Lender failed to notify the Administrative Agent of a change in circumstances which rendered the exemption from, or reduction of, withholding tax ineffective, or for any other reason) such Lender shall indemnify the Administrative Agent fully for all amounts paid, directly or indirectly, by the Administrative Agent as tax or otherwise, including penalties and interest, and including any taxes imposed by any jurisdiction on the amounts payable to the Administrative Agent under this Section, together with all costs and expenses (including Attorney Costs). The obligation of the Lenders under this subsection shall survive the payment of all Obligations and the resignation or replacement of the Administrative Agent.

(a) whether or not the transactions contemplated hereby are consummated, pay or reimburse the Administrative Agent within five (5) Business Days after demand (subject to Subsection 5.01(c)) for all reasonable costs and expenses incurred by the Administrative Agent in connection with the development, preparation, delivery, administration and execution of, and any amendment, supplement, waiver or modification to (in each case, whether or not consummated), this Agreement, any Loan Document and any other documents prepared in connection herewith or therewith, and the consummation of the transactions contemplated hereby and thereby, including Attorney Costs incurred by the Administrative Agent with respect thereto except such costs and expenses as may be incurred by the assignor Lenders or Assignee under Subsection 11.08(c); and

The agreements in this Section shall survive payment of all other Obligations.

11.06 Payments Set Aside. To the extent that the Company makes a payment to the Administrative Agent or the Lenders, or the Administrative Agent or the Lenders exercise their right of set-off, and such payment or the proceeds of such set-off or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Administrative Agent or such Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any Insolvency Proceeding or otherwise, then (a) to the extent of such recovery the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such set-off had not occurred, and (b) each Lender severally agrees to pay to the Administrative Agent upon demand its pro rata share of any amount so recovered from or repaid by the Administrative Agent.

11.08 Assignments, Participations, etc.

(a) Any Lender may upon written consent of the Administrative Agent, the Issuing Lender and Borrower, which consent shall not be unreasonably withheld (provided at any time that an Event of Default has occurred and is continuing, no approval from the Company shall be required), at any time, assign and delegate to one or more Eligible Assignees (provided that no written consent of the Administrative Agent or the Issuing Lender shall be required in connection with any assignment and delegation by the Lender to an Eligible Assignee that is an Affiliate of such Lender) (each an “Assignee”) all, or any ratable part of all in a minimum commitment amount at least equal to $5,000,000 or in $1,000,000 increments in excess thereof, of the Loans, the Commitments, and the other rights and obligations of such Lender hereunder; provided, however, that the Company and the Administrative Agent may continue to deal solely and directly with such Lender in connection with the interest so assigned to an Assignee until (i) written notice of such assignment, together with payment instructions, addresses and related information with respect to the Assignee, shall have been given to the Company and

the Administrative Agent by such Lender and the Assignee; (ii) such Lender and its Assignee shall have delivered to the Company and the Administrative Agent an Assignment and Acceptance in the form of Exhibit D (“Assignment and Acceptance”) together with any Note or Notes subject to such assignment and (iii) the assignor Lender or Assignee has paid to the Administrative Agent a processing fee in the amount of $3,000.00.

(b) From and after the date that the Administrative Agent notifies the assignor Lender that it has received an executed Assignment and Acceptance and payment of the above-referenced processing fee, (i) the Assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, shall have the rights and obligations of a Lender under the Loan Documents, and (ii) the assignor Lender shall, to the extent that rights and obligations hereunder and under the other Loan Documents have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under the Loan Documents.

(c) Within five (5) Business Days after its receipt of notice by the Administrative Agent that it has received an executed Assignment and Acceptance and payment of the processing fee, (and provided that it consents to such assignment in accordance with Subsection 11.08(a)) the Company shall execute and deliver to the Administrative Agent, new Notes evidencing such Assignee’s assigned Loans and Commitment and, if the assignor Lender has retained a portion of its Loans and its Commitment, replacement Notes in the principal amount of the Loans retained by the assignor Lender (such Notes to be in exchange for, but not in payment of, the Notes held by such Lender, which shall be cancelled upon receipt of the new or replacement Notes). Immediately upon each Assignee’s making its processing fee payment under the Assignment and Acceptance, this Agreement shall be deemed to be amended to the extent, but only to the extent, necessary to reflect the addition of the Assignee and the resulting adjustment of the Commitments arising therefrom. The Commitment allocated to each Assignee shall reduce such Commitments of the assigning Lender pro tanto.

(d) Any Lender may at any time sell to one or more commercial Lenders or other Persons not Affiliates of the Company (a “Participant”) participating interests in any Loans, the Commitment of that Lender and the other interests of that Lender (the “originating Lender”) hereunder and under the other Loan Documents; provided, however, that (i) the originating Lender’s obligations under this Agreement shall remain unchanged, the originating Lender shall remain a Lender for all purposes hereof and the other Loan Documents to which such originating Lender is a party, and the Participant may not become a Lender for purposes hereof or for any other of the Loan Documents, (ii) the originating Lender shall remain solely responsible for the performance of such obligations, (iii) the Company and the Administrative Agent shall continue to deal solely and directly with the originating Lender in connection with the originating Lender’s rights and obligations under this Agreement and the other Loan Documents, and (iv) no Lender shall transfer or grant any participating interest under which the Participant has rights to approve any amendment to, or any consent or waiver with respect to, this Agreement or any other Loan Document, except to the extent such amendment, consent or waiver would require unanimous consent of the Lenders. In the case of any such participation, the Participant shall not have any rights under this Agreement, or any of the other Loan Documents (the Participant’s rights against the granting Lender in respect of such participation being those set forth in the agreement creating or evidencing such participation with such Lender), and all amounts payable by the Company hereunder shall be determined as if such Lender had not sold such participation; except that, if amounts outstanding under this Agreement are due and unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall be deemed to have the right of set-off in respect of its participating interest in amounts owing under this Agreement to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement.

(e) Each Lender agrees to take normal and reasonable precautions and exercise due care to maintain the confidentiality of all information identified as “confidential” or “secret” by the Company and provided to it by the Company or any of its Subsidiaries, or by the Administrative Agent on such Company’s or Subsidiary’s behalf, under or in connection with this Agreement or any other Loan Document, and neither it nor any of its Affiliates shall use any such information other than in connection with or in enforcement of this Agreement and the other Loan Documents; except to the extent such information (i) was or becomes generally available to the public other than as a result of disclosure by any Lender or the Administrative Agent, or (ii) was or becomes available on a non-confidential basis from a source other than the Company, provided that such source is not bound by a confidentiality agreement with the Company known to the Lender; provided, however, that any Lender may disclose such information (A) at the request or pursuant to any requirement of any Governmental Authority to which the Lender is subject or in connection with an examination of such Lender by any such authority; (B) pursuant to subpoena or other court process; (C) when required to do so in accordance with the provisions of any applicable Requirement of Law; (D) to the extent reasonably required in connection with any litigation or proceeding to which the Administrative Agent, any Lender or their respective Affiliates may be party; (E) to the extent reasonably required in connection with the exercise of any remedy hereunder or under any other Loan Document; (F) to such Lender’s independent auditors and other professional advisors; (G) to any Affiliate of such Lender, or to any Participant or Assignee, actual or potential, provided that such Affiliate, Participant or Assignee agrees to keep such information confidential to the same extent required of the Lenders hereunder, and (H) as to any Lender, as expressly permitted under the terms of any other document or agreement regarding confidentiality to which the Company is party or is deemed party with such Lender.

(f) Notwithstanding any other provision in this Agreement, any Lender may at any time create a security interest in, or pledge, all or any portion of its rights under and interest in this Agreement and the Notes held by it in favor of any Federal Reserve Lender in accordance with Regulation A of the FRB or U.S. Treasury Regulation 31 CFR §203.14, and such Federal Reserve Lender may enforce such pledge or security interest in any manner permitted under applicable law.

11.09 Interest.

(a) It is the intention of the parties hereto to comply with applicable usury laws, if any; accordingly, notwithstanding any provision to the contrary in this Agreement, the Notes or in any of the other Loan Documents securing the payment hereof or otherwise relating hereto, in no event shall this Agreement, the Notes or such other Loan Documents require or permit the payment, taking, reserving, receiving, collection, or charging of any sums constituting interest under applicable laws which exceed the maximum amount permitted by such laws. If any such excess interest is called for, contracted for, charged, taken, reserved, or received in connection with the Loans evidenced by the Notes or in any of the Loan Documents securing the payment thereof or otherwise relating thereto, or in any communication by the Administrative Agent, the Issuing Lender or the Lenders or any other Person to the Company or any other Person, or in the event all or part of the principal or interest thereof shall be prepaid or accelerated, so that under any of such circumstances or under any other circumstance whatsoever the amount of interest contracted for, charged, taken, reserved, or received on the amount of principal actually outstanding from time to time under the Notes or any other Loan Document shall exceed the maximum amount of interest permitted by applicable usury laws, then in any such event it is agreed as follows: (i) the provisions of this paragraph shall govern and control, (ii) neither any Company nor any other Person now or hereafter liable for the payment of the Notes or any Obligation shall be obligated to pay the amount of such interest to the extent such interest is in excess of the maximum amount of interest permitted by applicable usury laws, (iii) any such excess which is or has been received notwithstanding this paragraph shall be credited against the then unpaid principal balance of the Notes or other

Obligations, as applicable, or, if the Notes or other Obligations, as applicable, have been or would be paid in full, refunded to the Company, and (iv) the provisions of this Agreement, the Notes and the other Loan Documents securing the payment thereof and otherwise relating thereto, and any communication to the Company, shall immediately be deemed reformed and such excess interest reduced, without the necessity of executing any other document, to the maximum lawful rate allowed under applicable laws as now or hereafter construed by courts having jurisdiction hereof or thereof. Without limiting the foregoing, all calculations of the rate of the interest contracted for, charged, collected, taken, reserved, or received in connection with the Notes, this Agreement or any other Loan Document which are made for the purpose of determining whether such rate exceeds the maximum lawful rate shall be made to the extent permitted by applicable laws by amortizing, prorating, allocating and spreading during the period of the full term of the Loans or other Obligations, as applicable, including all prior and subsequent renewals and extensions, all interest at any time contracted for, charged, taken, collected, reserved, or received. The terms of this paragraph shall be deemed to be incorporated in every document and communication relating to the Notes, the Loans or any other Loan Document.

(b) Texas Finance Code, Chapter 346 (formerly Tex. Rev. Civ. Stat., Title 79, Chapter 15), which regulates certain revolving loan accounts and revolving tri-party accounts, shall not apply to any revolving loan accounts created under the Notes, this Agreement or the other Loan Documents or maintained in connection therewith.

(c) To the extent that the interest rate laws of the State of Texas are applicable to the Loans or any other Obligations, the applicable interest rate ceiling is the weekly ceiling (formerly the indicated rate ceiling) determined in accordance with Tex. Rev. Civ. Stat., Title 79, Article 5069-1D.003, also codified at Texas Finance Code, Section 303.301 (formerly Article 5069-1.01(a)(1)), and, to the extent that this Agreement, the Notes or any other Loan Document is deemed an open end account as such term is defined in Tex. Rev. Civ. Stat., Title 79, Article 5069-1B.002(14), also codified at Texas Finance Code Section 3.01.001(3) (formerly Article 5069-1.01(f)), the payee retains the right to modify the interest rate in accordance with applicable law.

11.10 Indemnity and Subrogation. In addition to all such rights of indemnity and subrogation as any Guarantor may have under applicable law, the Company agrees that in the event a payment shall be made by any Guarantor under a Guaranty in respect of a Loan to the Company the Company shall indemnify such Guarantor for the full amount of such payment and such Guarantor shall be subrogated to the rights of the person to whom such payment shall have been made to the extent of such payment subject to the provisions of the Guaranty executed by such Guarantor. Notwithstanding any provision of this Agreement to the contrary, all rights of any Guarantor under this Section 11.10 and all other rights of indemnity, contribution or subrogation under applicable law or otherwise shall be fully subordinated to the indefeasible payment in full of the Obligations, and no payments may be made in respect of such rights of indemnity, contribution or subrogation until all the Obligations have been paid in full and all Commitments have expired. No failure on the part of the Company to make the payments required by this Section (or any other payments required under applicable law or otherwise) shall in any respect limited the obligations and liabilities required under applicable law or otherwise) shall in any respect limit the obligations and liability of any Guarantor with respect to any Guaranty, and Guarantor shall remain liable for the full amount of the obligation of such Guarantor under each such Guaranty in accordance therewith.

11.11 Collateral Matters; Derivative Contracts. The benefit of the Security Documents and of the provisions of this Agreement relating to any collateral securing the Indebtedness shall also extend to and be available to any Lender or any Affiliate of a Lender that is counterparty to any Derivative Contract with the Company or any of its Subsidiaries (including any Derivative Contract between such

Persons in existence prior to the Effective Date) on a pro rata basis in respect of any obligations of the Company or any of its Subsidiaries which arise under any such Derivative Contract; provided that the applicable counterparty must have provided Administrative Agent written notice of the existence thereof (such notice to include a summary of the contract date, price, volumes and other terms of such Derivative Contracts as Administrative Agent may reasonably request) and such transaction must not otherwise be prohibited under this Agreement at the time it was entered into and provided further that if such Lender or Affiliate ceases to be a Lender (a) its Derivative Contract obligations shall be secured pari passu with the Lenders’ Obligations but only to the extent such counterparty’s obligations arise from transactions entered into at the time such counterparty was a Lender hereunder or an Affiliate of a Lender hereunder, and (b) such counterparty shall have no voting rights under any Loan Documents as a result of the existence of obligations owed to it under any such Derivative Contract. For the avoidance of doubt, a Person ceases to be a Lender hereunder if (i) pursuant to an assignment, such Person ceases to have any Commitment, Loans and LC Obligation hereunder or (ii) the Commitments of all of the Lenders hereunder have been terminated and all principal, interest and other amounts outstanding under this Agreement have been paid in full in cash (whether as a result of repayment at maturity, prepayment in connection with the refinancing of this Agreement or otherwise).

11.12 USA Patriot Act Notice. Each Lender hereby notifies the Loan Parties that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies such Loan Party, which information includes the name and address of such Loan Party and other information that will allow such Lender to identify the Loan Party, insofar as it is needed to comply with the Act, in accordance with the Act. Each Loan Party hereby represents and warrants to Administrative Agent and each Lender that such Loan Party is not a country, individual or entity named on the “Specifically Designated National and Blocked Persons” list issued by the Office of Foreign Asset Control of the Department of the Treasury of the United States of America.

11.13 Automatic Debits of Fees. With respect to any commitment fee, arrangement fee, letter of credit fee or other fee, or any other cost or expense (including Attorney Costs) due and payable to the Administrative Agent under the Loan Documents, the Company hereby irrevocably authorizes the Administrative Agent, after giving reasonable prior notice to the Company, to debit any deposit account of the Company with the Administrative Agent in an amount such that the aggregate amount debited from all such deposit accounts does not exceed such fee or other cost or expense. If there are insufficient funds in such deposit accounts to cover the amount of the fee or other cost or expense then due, such debits will be reversed (in whole or in part, in the Administrative Agent’s sole discretion) and such amount not debited shall be deemed to be unpaid. No such debit under this Section shall be deemed a set-off.

11.14 Notification of Addresses, Lending Offices, Etc. Each Lender shall notify the Administrative Agent in writing of any changes in the address to which notices to the Lender should be directed, of addresses of any Lending Office, of payment instructions in respect of all payments to be made to it hereunder and of such other administrative information as the Administrative Agent shall reasonably request.

11.15 Counterparts. This Agreement may be executed in any number of separate counterparts, each of which, when so executed, shall be deemed an original, and all of said counterparts taken together shall be deemed to constitute but one and the same instrument.

11.16 Severability. The illegality or unenforceability of any provision of this Agreement or any instrument or agreement required hereunder shall not in any way affect or impair the legality or

enforceability of the remaining provisions of this Agreement or any instrument or agreement required hereunder.

11.17 No Third Parties Benefited. This Agreement is made and entered into for the sole protection and legal benefit of the Company, the other Loan Parties, the Lenders, the Administrative Agent and the Agent-Related Persons, and their permitted successors and assigns, and no other Person shall be a direct or indirect legal beneficiary of, or have any direct or indirect cause of action or claim in connection with, this Agreement or any of the other Loan Documents.

11.18 Governing Law, Jurisdiction and Waiver of Jury Trial. The provisions of Section 11.19 hereof shall govern the resolution of any Dispute (as such term is defined in such Section 11.19). If, however, the provisions of Section 11.19 are not invoked as therein provided, the following provisions shall apply:

(a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF TEXAS AND APPLICABLE FEDERAL LAW; AND THE ADMINISTRATIVE AGENT AND THE LENDERS SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

(b) EACH LOAN PARTY PARTY HERETO IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS IN ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO IT AT ITS ADDRESS SET FORTH IN SCHEDULE 11.02. SUCH SERVICE TO BECOME EFFECTIVE TEN DAYS AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE ADMINISTRATIVE AGENT OR ANY LENDER TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW.

(c) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE ▇▇▇▇▇ ▇▇ ▇▇▇▇▇ ▇▇ ▇▇ ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇ FOR THE SOUTHERN DISTRICT OF TEXAS, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH LOAN PARTY CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. EACH LOAN PARTY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING 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 ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF THIS AGREEMENT OR ANY DOCUMENT RELATED HERETO. EACH LOAN PARTY WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, AND CONSENTS TO THE SERVICE OF PROCESS IN ANY SUCH LEGAL ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO IT AT ITS ADDRESS FOR NOTICES SET FORTH HEREIN, SUCH SERVICE TO BECOME EFFECTIVE TEN DAYS AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE ADMINISTRATIVE AGENT OR ANY LENDER TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW.

(d) THE LOAN PARTIES, THE LENDERS AND THE ADMINISTRATIVE AGENT EACH WAIVES ITS RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR

THEREBY, IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES AGAINST ANY OTHER PARTY OR ANY AGENT-RELATED PERSON, PARTICIPANT OR ASSIGNEE, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE. THE LOAN PARTIES, THE LENDERS AND THE ADMINISTRATIVE AGENT EACH AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

11.19 ARBITRATION.

(a) Arbitration. Upon the demand of any party to any Loan Document, any Dispute shall be resolved by binding arbitration (except as set forth in (e) below) in accordance with the terms hereof. A “Dispute” shall mean any action, dispute, claim or controversy of any kind, whether in contract or tort, statutory or common law, legal or equitable, now existing or hereafter arising under or in connection with, or in any way pertaining to, any of the Loan Documents, or any past, present or future extensions of credit and other activities, transactions or obligations of any kind related directly or indirectly to any of the Loan Documents, including without limitation, any of the foregoing arising in connection with the exercise of any self-help, ancillary or other remedies pursuant to any of the Loan Documents. Any party may by summary proceedings bring an action in court to compel arbitration of a Dispute. Any party who fails or refuses to submit to arbitration following a lawful demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any Dispute.

(b) Governing Rules. Arbitration proceedings shall be administered by the American Arbitration Association (“AAA”) or such other administrator as the parties shall mutually agree upon in accordance with the AAA Commercial Arbitration Rules. All Disputes submitted to arbitration shall be resolved in accordance with the Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law provision in any of the Loan Documents. The arbitration shall be conducted at a location in Texas selected by the AAA or other administrator. If there is any inconsistency between the terms hereof and any such rules, the terms and procedures set forth herein shall control. All statutes of limitation applicable to any Dispute shall apply to any arbitration proceeding. All discovery activities shall be expressly limited to matters directly relevant to the Dispute being arbitrated. Judgment upon any award rendered in an arbitration may be entered in any court having jurisdiction; provided however, that nothing contained herein shall be deemed to be a waiver by any party that is a Lender of the protections afforded to it under 12 U.S.C. §91 or any similar applicable state law.

(c) No Waiver; Provisional Remedies, Self-Help and Foreclosure. No provision hereof shall limit the right of any party to exercise self-help remedies such as setoff, foreclosure against or sale of any real or personal property collateral or security, or to obtain provisional or ancillary remedies, including without limitation injunctive relief, sequestration, attachment, garnishment or the appointment of a receiver, from a court of competent jurisdiction before, after or during the pendency of any arbitration or other proceeding. The exercise of any such remedy shall not waive the right of any party to compel arbitration hereunder.

(d) Arbitrator Qualifications and Powers; Awards. Arbitrators must be active members of the Texas State Bar with expertise in the substantive laws applicable to the subject matter of the Dispute. Arbitrators are empowered to resolve Disputes by summary rulings in response to motions filed prior to the final arbitration hearing. Arbitrators (i) shall resolve all Disputes in accordance with the substantive law of the state of Texas, (ii) may grant any remedy or relief that a court of the state of Texas could order or grant within the scope hereof and such ancillary relief as is necessary to make effective any award, and (iii) shall have the power to award recovery of all costs and fees, to impose sanctions and to take such other actions as they deem necessary to the same extent a judge could pursuant to the Federal Rules of Civil Procedure, the Texas rules of civil procedure, as set forth in the Texas Code of Civil Procedure and the Court Rules or other applicable law. Any Dispute in which the amount in controversy is $5,000,000 or less shall be decided by a single arbitrator who shall not render an award of greater than $5,000,000 (including damages, costs, fees and expenses). By submission to a single arbitrator, each party expressly waives any right or claim to recover more than $5,000,000. Any Dispute in which the amount in controversy exceeds $5,000,000 shall be decided by majority vote of a panel of three arbitrators; provided however, that all three arbitrators must actively participate in all hearings and deliberations.

(e) Judicial Review and Other Exceptions. Notwithstanding anything herein to the contrary: (i) In any arbitration in which the amount in controversy exceeds $25,000,000, the arbitrators shall be required to make specific, written findings of fact and conclusions of law. In such arbitrations (A) the arbitrators shall not have the power to make any award which is not supported by substantial evidence or which is based on legal error, (B) an award shall not be binding upon the parties unless the findings of fact are supported by substantial evidence and the conclusions of law are not erroneous under the substantive law of the state of Texas, and (C) the parties shall have in addition to the grounds referred to in the Federal Arbitration Act for vacating, modifying or correcting an award the right to judicial review of (1) whether the findings of fact rendered by the arbitrators are supported by substantial evidence, and (2) whether the conclusions of law are erroneous under the substantive law of the state of Texas. Judgment confirming an award in such a proceeding may be entered only if a court determines the award is supported by substantial evidence and not based on legal error under the substantive law of the state of Texas; and (ii) Determinations of the Borrowing Base pursuant to Section 2.05 hereof shall not be subject to review or challenge under this Section 11.19.

(f) Miscellaneous. To the maximum extent practicable, the AAA, the arbitrators and the parties shall take all action required to conclude any arbitration proceeding within 180 days of the filing of the Dispute with the AAA. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except for disclosures of information by a party required in the ordinary course of its business, by applicable law or regulation, or to the extent necessary to exercise any judicial review rights set forth herein. If more than one agreement for arbitration by or between the parties potentially applies to a Dispute, the arbitration provision most directly related to the Loan Documents or the subject matter of the Dispute shall control. This arbitration provision shall survive termination, amendment or expiration of any of the Loan Documents or any relationship between the parties.

11.20 Entire Agreement. This Agreement, together with the other Loan Documents, embodies the entire agreement and understanding among the Company, its Subsidiaries, the Lenders and the Administrative Agent, and supersedes all prior or contemporaneous agreements and understandings of such Persons, verbal or written, relating to the subject matter hereof and thereof.

11.21 NO ORAL AGREEMENTS. THIS WRITTEN LOAN AGREEMENT, TOGETHER WITH THE OTHER WRITTEN LOAN DOCUMENTS EXECUTED IN CONNECTION HEREWITH,

REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES 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.
