ARTICLE II

TERMS OF FACILITIES

2.1. Reducing Revolving Line of Credit and Letter of Credit Facilities.

2.1.1. (i) During the Revolving Credit Period, and if no Default exists, each Lender severally agrees, subject to the other terms and conditions of this Agreement, to make Loans to the Borrower from time to time in amounts not to exceed, in the aggregate at any one time outstanding, its Available Commitment. Each Loan shall be made as part of an Advance consisting of Loans made by the Lenders ratably in accordance with their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not

relieve any other Lender of its obligations hereunder; provided that the Commitments are several and neither the Administrative Agent nor any Lender shall be responsible for any other Lender’s failure to make Loans as required.

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

(iii) At the commencement of each Interest Period for any Eurodollar Advance, such Advance shall be in an aggregate amount that is an integral multiple of $100,000 and not less than $1,000,000. At the time that each FLR Advance is made, such Advance shall be in an aggregate amount that is an integral multiple of $100,000 and not less than $500,000; provided that an FLR Advance may be in an aggregate amount that is equal to the aggregate Unused Available Commitment of the Lenders. Advances of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of three (3) Eurodollar Advances outstanding. Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Eurodollar Advances if the Interest Period requested with respect thereto would end after the Final Maturity Date.

2.1.2. No Lender shall be obligated to lend to the Borrower, and the Borrower shall not be entitled to borrow hereunder, any amount which would cause the sum of the outstanding principal amount of the Note held by such Lender plus such Lender’s Percentage Share of the Letter of Credit Exposure, to exceed its Available Commitment.

2.1.3. Upon the terms and conditions and relying on the representations and warranties contained in this Agreement,

(i) the Administrative Agent, as issuing bank for the Lenders, agrees, from the date of this Agreement until the date which is 120 days prior to the Final Maturity Date, to issue, on behalf of the Lenders ratably in proportion to in their respective Commitments, standby letters of credit hereunder for the account of the Borrower, and to renew and extend standby Letters of Credit.

(ii) letters of credit shall be issued hereunder and Letters of Credit shall be renewed or extended from time to time on any Business Day designated by the Borrower following the receipt by the Administrative Agent of the written (or oral, confirmed promptly in writing) request by a Responsible Representative of the Borrower therefor and, if for the issuance of a new letter of credit hereunder, a Letter of Credit Application; provided, however, that:

(a) the expiry date of such requested letter of credit cannot be later than the earlier of (1) 365 days from the date of issuance, unless automatically renewable by its terms, or, if issued in favor of the Texas Railroad Commission, 15 months following the date of

issuance, (2) the last date before which the Borrowing Base is scheduled to reduce to an amount less than the sum of the maximum drawable amount of the requested letter of credit plus the undrawn amount of all outstanding Letters of Credit which, by their terms, might be outstanding on such reduction date or (3) 30 days prior to the Final Maturity Date;

(b) the aggregate outstanding principal balance of the Notes of the Lenders plus the Letter of Credit Exposure shall not exceed at any time the Borrowing Base;

(d) with the exception of standby letters of credit to support plugging bond obligations of the Borrower (for which there shall be no minimum dollar amount or maximum number of such letters of credit), no letter of credit shall be issued hereunder in an amount less than $25,000; and

(e) the Administrative Agent shall not be obligated to issue a letter of credit pursuant hereto or to renew or extend a Letter of Credit, and the Borrower shall not be entitled to have a letter of credit issued pursuant hereto or to have a Letter of Credit renewed or extended, if the issuance of the requested letter of credit or the renewal or extension of an existing Letter of Credit would cause, after taking into account the mandatory reductions in the Borrowing Base required during the proposed term of such requested letter of credit or existing Letters of Credit, the sum of the undrawn amount of all Letters of Credit plus the aggregate outstanding principal amount of the Notes, to exceed the Aggregate Available Commitment.

(iii) except as otherwise permitted by clause (ii)(d) above, the Administrative Agent shall have no obligation to issue a letter of credit hereunder if as a result thereof, there would be outstanding more than five (5) standby Letters of Credit under clause (i) above.

2.1.4. With respect to each Letter of Credit issued by the Administrative Agent, the Lenders shall be deemed to have acquired, ratably in proportion to their respective Commitments, participations in such Letter of Credit (and any renewals or extensions thereof) in the maximum amount which might be drawn under such Letter of Credit.

2.1.5. With respect to each Letter of Credit issued by the Administrative Agent, each Lender shall be unconditionally and irrevocably liable, without regard (i) to the occurrence of any Default or Event of Default or (ii) the failure of the Administrative Agent, the Borrower or any other Person to satisfy any condition herein or otherwise or (iii) any contrary provisions of this Agreement, ratably in the proportion that its Commitment bears to the Aggregate Commitment, to reimburse the Administrative Agent on demand for the amount of each Letter of Credit Payment under such Letter of Credit. Each Letter of Credit Payment shall be deemed to be a Loan by each Lender to the extent of funds delivered by such Lender to the Administrative Agent with respect to such Letter of Credit Payment and shall, to such extent, be deemed a Loan under and shall be evidenced by the Note of such Lender.

2.1.6. Each Lender agrees to indemnify the Administrative Agent on a current basis, as the issuer of each Letter of Credit, and the officers, directors, employees, agents, attorneys-in-fact and affiliates of the Administrative Agent (to the extent not reimbursed by the

Borrower and without limiting the obligation of the Borrower to do so), ratably in the proportion that its Commitment bears to the Aggregate Commitment, from and against any and all liabilities, claims, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of any kind whatsoever which may at any time (including any time following the payment and performance of all obligations and the termination of this Agreement) be imposed on, incurred by or asserted against the Administrative Agent as the issuer of such Letter of Credit or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates in any way relating to or arising out of this Agreement or such Letter of Credit or any action taken or omitted by the Administrative Agent as the issuer of such Letter of Credit or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates under or in connection with any of the foregoing, INCLUDING ANY LIABILITIES, CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS IMPOSED, INCURRED OR ASSERTED AS A RESULT OF THE NEGLIGENCE, WHETHER SOLE, CONTRIBUTORY OR CONCURRENT, OF THE ADMINISTRATIVE AGENT AS THE ISSUER OF SUCH LETTER OF CREDIT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting solely from the gross negligence or willful misconduct of the Administrative Agent as the issuer of a Letter of Credit. The agreements in this Section shall survive the payment and performance of all obligations and the termination of this Agreement.

2.2. Method of Borrowing and Obtaining Letters of Credit.

2.2.1. The Borrower shall give the Administrative Agent an irrevocable notice (a “Notice of Borrowing”) not later than (a) in the case of a Eurodollar Advance, not later than 11:00 a.m. CT, three (3) Business Days before the date of such proposed Advance or (b) in the case of an FLR Advance, not later than 12:00 p.m. CT on the date of such proposed Advance. Each Notice of Borrowing shall specify each of the following:

(i) the Borrowing Date, which shall be a Business Day, of such requested Advance.

(ii) the aggregate amount of such requested Advance.

(iii) whether such Advance is to be an FLR Advance or a Eurodollar Advance.

(iv) in the case of a Eurodollar Advance, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period.”

If no election as to the Type of Advance is specified, then the requested Advance shall be an FLR Advance. If no Interest Period is specified with respect to any requested Eurodollar Advance, then the Borrower shall be deemed to have selected an Interest Period of one (1) month’s duration. Each Notice of Borrowing shall constitute a representation by the Borrower

that (a) the amount of the requested Advance shall not cause the total principal of the Notes plus the Letter of Credit Exposure to exceed the Aggregate Commitment and (b) no Default is in existence at the time of delivery to the Administrative Agent of such Notice of Borrowing.

2.2.2. Upon receipt of a Notice of Borrowing, the Administrative Agent shall promptly notify each Lender of the contents thereof and of such Lender’s share of the requested Advance, and thereafter such Notice of Borrowing shall not be revocable by the Borrower.

2.2.3. (a) Each Lender shall make each Loan to be made by it hereunder on the proposed Borrowing Date thereof by wire transfer of immediately available funds by 2:00 p.m. CT to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained at the Administrative Agent. Nothing herein shall be deemed to obligate any Lender to obtain the funds for its Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for its Loan in any particular place or manner.

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

2.2.4. The Borrower shall give the Administrative Agent an irrevocable request for a letter of credit prior to 12:00 p.m. CT at least three (3) Business Days before each such requested letter of credit under Section 2.1, by completing and delivering an irrevocable Notice of Borrowing together with a completed and executed Letter of Credit Application. The Letter of Credit Application must be completed in a manner and shall use such wording as is acceptable to the Administrative Agent.

2.2.5. Upon receipt of the Letter of Credit Application, the Administrative Agent shall issue such letter of credit if the conditions of Section 2.1.3, Article V or elsewhere herein have been satisfied.

2.2.6. Subject to the terms hereof, in the event that any beneficiary of a Letter of Credit shall have taken the steps necessary in the sole judgment of the Administrative Agent to obligate or permit the Administrative Agent to make a payment under such Letter of Credit, the Borrower shall be deemed to have delivered to the Administrative Agent a Notice of Borrowing under Section 2.2 for an Advance in the amount of such payment amount, regardless of any limitations or unsatisfied conditions set forth herein or if a Default exists. The Administrative Agent shall pay over the proceeds of such Advance to itself as reimbursement for amounts paid by the Administrative Agent to the beneficiary under such Letter of Credit.

2.3. Notes.

2.3.1. The Loans of each Lender shall be evidenced by a Note issued by the Borrower, payable to the order of such Lender.

2.3.2. Upon receipt of each Lender’s Note pursuant to Section 5.2.2, the Administrative Agent shall promptly forward such Note to such Lender.

2.3.3. The outstanding principal of the Note of a Lender reflected by the notations (whether handwritten, electronic or otherwise) by such Lender on its records shall be deemed rebuttably presumptive evidence of the principal amount owing on its Note.

2.3.4. Each Lender will record on its books each Loan and the particulars thereof (e.g., date and amount) and each payment of principal or interest made by the Borrower with respect thereto, and may, if such Lender so elects in connection with any transfer or enforcement of its Note, endorse on the schedule (modified as such Lender shall deem advisable) forming a part thereof appropriate notations to evidence the foregoing information with respect to each such Loan then outstanding; provided that the failure of any Lender to make any such recordation or endorsement shall not affect the obligations of the Borrower hereunder or under its Note. Each Lender is hereby irrevocably authorized by the Borrower so to endorse its Note and to attach to and make a part of its Note a continuation of any such schedule (modified as such Lender shall deem advisable) as and when required.

2.4. Certain Payments and Prepayments of Principal.

2.4.1. If at any time the aggregate principal of the Notes outstanding plus the Letter of Credit Exposure exceeds the Borrowing Base then in effect, the Borrower shall on the day of such occurrence, repay the principal of the Notes in an amount equal to such excess, except that if the circumstances described in this Section are the direct result of a decrease of the Borrowing Base under Section 2.8.1, then the provisions of Section 2.8.3 shall apply.

2.4.2. In the event that a prepayment of the Notes is required under the terms hereof, and the aggregate outstanding principal of the Notes is less than the amount required to be prepaid, the Borrower shall repay the entire balance of the Notes and, in accordance with the provisions of the relevant Letter of Credit Application executed by the Borrower or otherwise to the satisfaction of the Administrative Agent, deposit with the Administrative Agent as additional collateral securing the Obligations, an amount of immediately available funds equal to the difference of the Letter of Credit Exposure less the Borrowing Base.

2.5. Interest Rates; Payment of Interest.

2.5.1. Each Loan comprising an FLR Advance shall bear interest on the outstanding principal amount thereof, for each day from and including the date such FLR Advance is made or is automatically converted from a Eurodollar Advance into an FLR Advance pursuant to Section 2.9, to but excluding the date it is paid or is converted into a Eurodollar Advance pursuant to Section 2.9, at a rate per annum equal to the lesser of (a) the Floating Rate or, if applicable, such higher rate as is specified in Section 3.3 or (b) the Highest Lawful Rate.

2.5.2. Each Loan comprising a Eurodollar Advance shall bear interest on the outstanding principal amount thereof from and including the first day of the Interest Period applicable thereto to (but not including) the last day of such Interest Period equal to the lesser of (a) the Adjusted LIBOR Rate in effect for such Advance or, if applicable, such higher rate as is specified in Section 3.3 or (b) the Highest Lawful Rate.

2.5.3. Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and on the Final Maturity Date; provided that interest accrued pursuant to Section 3.3 shall be payable on demand.

2.5.4. Each determination hereunder of interest on the Notes and fees hereunder based on per annum calculations shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day), subject to the limitations of the Highest Lawful Rate. All interest rates applicable hereunder shall be determined by the Administrative Agent, and such determinations shall be conclusive absent manifest error, and be binding upon the parties hereto.

2.5.5. If prior to the commencement of any Interest Period for a Eurodollar Advance:

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

(b) the Administrative Agent is advised by any Lender that the Adjusted LIBOR Rate or LIBOR Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lender of making or maintaining its or their Loans included in such Advance for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or electronic means as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Advance to, or continuation of any Advance as, a Eurodollar Advance shall be ineffective, and (ii) if any Notice of Borrowing requests a Eurodollar Advance, such Advance shall be made as an FLR Advance.

2.5.6. Each change in the rate of interest charged hereunder shall become effective automatically and without notice to the Borrower upon the effective date of each change in the Floating Rate or the Highest Lawful Rate, as the case may be.

2.5.7. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan into an FLR Loan other than on the last day of the Interest Period applicable thereto, or (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBOR Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the Eurodollar market.

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

2.6. Unused Available Commitment Fees; Engineering Fees; Facility Fees; Letter of Credit Fees; Authorized Payments by Lender; Processing Fee.

2.6.1. The Borrower shall pay to the Administrative Agent for the ratable benefit of the Lenders a commitment fee of one-half of one percent (1/2 of 1.00%) per annum, calculated daily on the actual number of days the Commitments are outstanding on the amount of the Unused Available Commitments of the Lenders in effect from time to time, such commitment fee to be payable quarterly in arrears on each January 1, April 1, July 1, and October 1 occurring hereafter, and upon termination of the Commitments.

2.6.2. (i) No engineering fee shall be due from the Borrower on the Closing Date. Thereafter, if TCB is the sole Lender, the Borrower shall pay an engineering fee in the amount of $5,000 if the Administrative Agent’s internal engineers perform the engineering review of the Collateral or the actual fees and expenses of any third-party engineers retained by the Administrative Agent to prepare an engineering report, payable at the time of the Scheduled, Discretionary or Borrower Requested Determinations of the Borrowing Base referred to in Section 2.8.1 or at the time of a redetermination of the Borrowing Base required under Section 7.9.2. If TCB is not the sole Lender, the Borrower shall pay to the Administrative Agent for the ratable benefit of the Lenders an engineering fee in the amount of $5,000 multiplied by the number of Lenders then party hereto, payable at the time of each Scheduled, Discretionary or Borrower Requested Determination of the Borrowing Base referred to in Section 2.8.1 or at the time of a redetermination of the Borrowing Base required under Section 7.9.2. In this connection, the Borrower may elect to have a third-party engineering report prepared by ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇ & Associates, Inc. or other independent engineering firm approved by the Administrative Agent.

2.6.3. To compensate the Lenders for the costs of the extension of credit hereunder, the Borrower shall pay to the Administrative Agent (i) on the Closing Date, a facility fee of one percent (1.00%) of the initial Borrowing Base for the ratable benefit of the Lenders minus the $4,985 work fee previously paid by the Borrower, and (ii) thereafter for the ratable benefit of the Lenders upon each determination of an increase in the Borrowing Base pursuant to Section 2.8.1, a facility fee in the amount of one percent (1.00%) of the amount by which the Borrowing Base is increased over that in effect on the date of determination.

2.6.4. The Borrower shall pay to the Administrative Agent at the time of each issuance of a letter of credit hereunder and at the time of each renewal (including extensions) of a Letter of Credit, (a) a letter of credit fee for the ratable benefit of the Lenders equal to the greater of (i) two percent (2.00%) per annum of the face amount of such letter of credit or Letter of Credit, as applicable, for the maximum number of days from such date of issuance or renewal, as applicable, to the expiry date of such letter of credit or Letter of Credit, as applicable, and (ii) $1,000, and (b) if TCB is not the sole Lender at the time of the issuance of a letter of credit or renewal of a Letter of Credit, as applicable, a letter of credit issuance fee for the sole account of the Administrative Agent equal to one-fourth of one percent (0.25%) per annum of the face amount of such letter of credit or Letter of Credit, as applicable, for the maximum number of days from such date of issuance or renewal, as applicable, to the expiry date of such letter of credit or Letter of Credit, as applicable.

2.6.5. At any time TCB is not the sole Lender hereunder, the Borrower agrees to pay to the Administrative Agent on each January 1^st occurring hereafter, exclusively for the account of the Administrative Agent, an agency fee in the amount of $5,000 multiplied by the number of Lenders at such time.

2.6.6. The Lenders are irrevocably authorized to make Loans under the Notes for the payment of the fees and expenses of the Administrative Agent and the Lenders required to be paid by the Borrower hereunder. The Administrative Agent shall pay over such Loan proceeds to itself or directly to such other Persons entitled to payment hereunder.

2.6.7. To compensate the Administrative Agent for the cost of processing requests for waivers, partial releases, amendments and consents regarding the provisions of this Agreement or the other Loan Documents, the Borrower shall pay to the Administrative Agent at the time of granting such waiver, providing such partial release, entering into such amendment or granting such consent, the amount of $2,500 for the Administrative Agent’s sole account plus such additional amounts as the Administrative Agent, the Lenders and the Borrower shall agree.

2.7. Termination of Credit Facilities; Maturity of Notes; Right of Borrower to Terminate Credit Facilities.

2.7.1. The obligations of each Lender to the Borrower under Section 2.1 shall, subject to its continuing obligation to fund Letters of Credit, terminate on the Final Maturity Date, unless terminated earlier in accordance with the terms hereof.

2.7.2. The Notes shall finally mature no later than the Final Maturity Date, and any unpaid principal of the Notes and accrued, unpaid interest thereon shall be due and payable on such date.

2.7.3. The Borrower shall have the right upon payment in full of the Obligations and the cancellation of all outstanding Letters of Credit, to cancel in full (but not in part) the credit facilities provided for herein, with no right of reinstatement.

2.8. Determination of Borrowing Base; Automatic Reductions in Borrowing Base; Borrowing Base Deficiency; Notice of Redeterminations; Requests for Reductions in Borrowing Base.

2.8.1. On the basis of the information furnished to the Administrative Agent hereunder and such other reports, appraisals and information as the Administrative Agent may reasonably deem appropriate, the Administrative Agent shall have the right to determine a new Borrowing Base two (2) times a year prior to the Final Maturity Date, such determinations to occur approximately six (6) months apart, or at any time it may elect if a Default has occurred which is continuing (the “Scheduled Determinations”), or at such other or additional times prior to the Final Maturity Date as the Administrative Agent or the Required Lenders in their reasonable discretion may elect (the “Discretionary Determinations”), and the Administrative Agent shall determine a new Borrowing Base at the Borrower’s expense at such additional times, but no more often than two (2) times in any 12-month period without the Administrative Agent’s consent, as the Borrower may request in connection with any material change in the value of the Oil and Gas Properties included in the most recent determination of the Borrowing Base (the “Borrower Requested Determinations”). Such determinations, if made, shall be in the Administrative Agent’s discretion and in accordance with the customary practices and standards of the Administrative Agent for loans of a similar nature as in effect at the time such determinations are made (except that the Administrative Agent may make adjustments to such determinations based on the practices and standards of each other Lender) and shall be conclusive as to the Borrower, and any increases in the Borrowing Base must be approved by all of the Lenders and shall be subject to each Lender’s complete credit approval process. There is no duty, implied or explicit, on the Administrative Agent or the Lenders to ever increase the Borrowing Base.

2.8.2. The Borrowing Base shall be automatically reduced as of the 1st day of each month, commencing September 1, 2011, and continuing on the first day of each month thereafter until the Final Maturity Date. Such reductions in the Borrowing Base each month shall be in the amount of $0 per month unless redetermined as herein permitted. At the time of each new Borrowing Base determination under Section 2.8.1, the Required Lenders in their sole discretion may increase the amount of such monthly reductions, and the Lenders may decrease the amount of such monthly reductions. Any decreases in the monthly reductions must be approved by all of the Lenders and shall be subject to each Lender’s complete credit approval process. There is no duty, implied or explicit, on the Administrative Agent or the Lenders to ever decrease the amount of the monthly Borrowing Base reduction amounts.

2.8.3. Upon the occurrence of a Borrowing Base Deficiency, the Borrower shall, within 30 days following written notice by the Administrative Agent of the

existence of such Borrowing Base Deficiency, do any one or more of the following in an aggregate amount at least equal to such Borrowing Base Deficiency: (i) prepay the principal of the Notes or (ii) cause to be created first and prior perfected Liens (subject only to Permitted Liens) in favor of the Administrative Agent for the benefit of the Lenders, by instruments reasonably satisfactory to the Administrative Agent, on producing Oil and Gas Properties (or in immediately available funds if the circumstances described in Section 2.4.2 are applicable) which in the opinion of each Lender would increase the Borrowing Base by an amount sufficient, in combination with clause (i) preceding, to eliminate such Borrowing Base Deficiency.

2.8.4. Upon each redetermination of the Borrowing Base, the Administrative Agent will notify the Borrower of such determination (which notice may be orally communicated to the Borrower and confirmed promptly thereafter in writing if the Borrowing Base is being decreased or the monthly Borrowing Base reduction amount is being increased), and the Borrowing Base and the amount by which the Borrowing Base shall be reduced so communicated to the Borrower shall become effective immediately upon such notification (or such other date as is stated in such notice and regardless of any Notice of Borrowing the Administrative Agent might have received) and shall remain in effect until the next subsequent redetermination of the Borrowing Base. The Administrative Agent may condition any increase in the Borrowing Base or decrease in the monthly Borrowing Base reduction amount upon the Borrower’s execution and return of the notice given under this Section, which notice may contain and require confirmations by the Borrower of representations, warranties and covenants contained in the Loan Documents.

2.8.5. The Borrower may at any time by written notice to the Administrative Agent request that the Borrowing Base be reduced (with no right of reinstatement) by an amount specified by the Borrower in such reduction notice, and the Borrowing Base shall be deemed so reduced upon receipt by the Administrative Agent of such reduction notice. Further, in the event the Borrower is advised of any increase in the Borrowing Base, the Borrower may decline to utilize the increased borrowing availability created thereby and by written notice to the Administrative Agent irrevocably refuse to accept all or a portion of such increase, but any such refusal notice received by the Administrative Agent more than five (5) Business Days following such increase in the Borrowing Base shall be treated as a Borrowing Base reduction notice under the immediately preceding sentence.

2.9. Interest Elections for Conversions and Continuations.

2.9.1. Each Advance initially shall be of the Type specified in the applicable Notice of Borrowing and, in the case of a Eurodollar Advance, shall have an initial Interest Period as specified in such Notice of Borrowing. Thereafter, the Borrower may elect to convert such Advance to a different Type or to continue such Advance and, in the case of a Eurodollar Advance, may elect Interest Periods therefor, all as provided in this Section 2.9. The Borrower may elect different options with respect to different portions of the affected Advance, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Advance, and the Loans comprising each such portion shall be considered a separate Advance.

2.9.2. To make an election pursuant to this Section 2.9, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Notice of Borrowing would be required under Section 2.2.1 if the Borrower were requesting an Advance of the Type resulting from such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by the Borrower.

2.9.3. Each telephonic and written Interest Election Request shall specify the following information and be in compliance with Section 2.1:

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

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

(iii) whether the resulting Advance is to be an FLR Advance or a Eurodollar Advance; and

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

If any such Interest Election Request requests a Eurodollar Advance but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one (1) month’s duration.

2.9.4. Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Advance.

2.9.5. If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Advance prior to the end of the Interest Period applicable thereto, then, unless such Advance is repaid as provided herein, at the end of such Interest Period such Advance shall be converted to an FLR Advance. Notwithstanding any contrary provision hereof, if an Event of Default or a Borrowing Base Deficiency has occurred and is continuing: (i) no outstanding Advance may be converted to or continued as a Eurodollar Advance (and any Interest Election Request that requests the conversion of any Advance to, or continuation of any Advance as, a Eurodollar Advance shall be ineffective) and (ii) unless repaid, each Eurodollar Advance shall be converted to an FLR Advance at the end of the Interest Period applicable thereto.

2.10. Request for Extension of Maturity. Following receipt by the Administrative Agent of a written request from the Borrower, given by the Borrower no earlier than six (6) months prior to the Final Maturity Date, each Lender agrees to consider, in accordance with the

customs and standards of such Lender in effect at such time for loans of a similar nature to the Loan and subject to each Lender’s complete approval process, a request by the Borrower to extend the Final Maturity Date. The Administrative Agent and Lenders might charge the Borrower fees to process any such request or to grant any such extension.

GENERAL PROVISIONS

3.1. General Provisions as to Payments and Loans.

3.1.1. All payments of principal and interest on the Notes and of fees hereunder shall be made, without setoff, deduction or counterclaim, by 12:00 p.m. CT on the date such payments are due in federal or other funds immediately available at the principal office of the Administrative Agent referred to in Article XIII and, if not made by such time or in immediately available funds, then such payment shall be deemed made when such funds are available to the Administrative Agent for its full and unrestricted use. Each payment delivered to the Administrative Agent for the account of any Lender shall be delivered promptly by the Administrative Agent to such Lender in the same type of funds that the Administrative Agent received at such Lender’s address specified pursuant to Article XIII. Whenever any payment of principal of or interest on the Notes or of fees hereunder shall be due on a day which is not a Business Day, the date for payment thereof shall be extended to the next succeeding Business Day. If the date for any payment is extended by operation of law or otherwise, interest thereon shall be payable for such extended time. The Administrative Agent is hereby authorized upon notice to the Borrower to charge the account of the Borrower maintained with the Administrative Agent, for each payment of principal, interest and fees as it becomes due hereunder.

3.1.2. All payments made by the Borrower on the Notes shall be made free and clear of, and without reduction by reason of, any Taxes.

3.2. Telephonic Notices; Notification to the Lenders of Advances, Interest Rates and Commitment Reductions; Non-Receipt of Funds by the Administrative Agent; Lending Installations.

3.2.1. The Borrower hereby authorizes the Administrative Agent to extend Advances, to issue letters of credit hereunder, to renew (including extensions) Letters of Credit and to transfer funds, and hereby authorizes the Lenders to make Loans, based on telephonic, e-mail or other electronic notices made by any Person the Administrative Agent or

any Lender in good faith believes to be acting on behalf of the Borrower. The Borrower agrees to deliver promptly to the Administrative Agent a written confirmation, if such confirmation is requested by the Administrative Agent or any Lender, of each telephonic, e-mail or other electronic notices, signed by a Responsible Representative. If the written confirmation differs in any material respect from the action taken by the Administrative Agent and the Lenders, the records of the Administrative Agent and the Lenders shall be prima facie, but not conclusive, evidence of the matter notwithstanding anything to the contrary in such confirmation.

3.2.2. The Administrative Agent will promptly notify each Lender of the contents of each Notice of Borrowing and credit facility or Borrowing Base reduction notice received by it hereunder. The Administrative Agent will give each Lender and the Borrower prompt notice of each change in the interest rate applicable to the Loans.

3.2.3. Unless the Borrower notifies the Administrative Agent prior to the date on which it is scheduled to make a payment of principal, interest or fees to the Administrative Agent for the account of the Lenders, that it does not intend to make such payment, the Administrative Agent may assume that such payment has been made. The Administrative Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If the Borrower has not in fact made such payment to the Administrative Agent, the recipient of such payment and the Borrower severally agree to pay to the Administrative Agent on demand the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Administrative Agent until the date the Administrative Agent recovers such amount at a rate per annum equal to (a) in the case of payment by a Lender, the Federal Funds Rate for such day or (b) in the case of payment by the Borrower, the Floating Rate.

3.2.4. Each Lender may book its Loans at any Lending Installation selected by such Lender and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation, and the Note payable to such Lender shall be deemed held by each Lender for the benefit of its Lending Installation. Each Lender may, by written or facsimile notice to the Administrative Agent and the Borrower, designate, or change any previous designation of, the Lending Installation through which Loans will be made by it and for whose account Note payments are to be made.

3.3. Default Interest. Unless waived by the Required Lenders, the principal of the Notes shall bear interest at the Default Rate during any time an Event of Default exists and, to the extent not prohibited by Law, overdue interest on the Notes shall bear interest at the Default Rate.

3.4. Prepayments Permitted.

3.4.1. The principal of the Notes and accrued interest thereon may be prepaid by the Borrower in whole or in part at any time and, except as otherwise specifically provided herein or with respect to Eurodollar Advances, shall be without premium or penalty. Each prepayment of Advances pursuant to this Section shall be applied, first, ratably to any FLR Advances then outstanding, and, second, to any Eurodollar Advances then outstanding, and if

Prepayments of Advances shall be accompanied by accrued interest to the date of prepayment. In the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

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

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

3.7. Ratable Benefit of the Lenders; Sharing of Burdens. As among the Lenders, the benefits and burdens of this Agreement shall be allocated in accordance with their respective Commitments except as specifically provided otherwise herein. In this connection, if the Commitments (and, thus, the Aggregate Commitment) of the Lenders have been terminated or reduced to zero dollars, then the amount of each Lender’s Commitment for the purposes of applying and interpreting those provisions of this Agreement which relate to indemnities of the Lenders and other burdens of this Agreement shall be determined on the basis of the Commitments as they existed immediately preceding such termination or reduction.

3.8. LATE CHARGE. If a payment remains unpaid for a period of 15 days or more from the date such payment is due, the payment shall subject to a delinquency charge equal to 5.00% of the amount of such payment, which charge shall be due upon demand, unless waived by the Required Lenders.

MISCELLANEOUS

9.1. Amendments and Waivers.

9.1.1. Any provision of this Agreement, the Notes or the other Loan Documents may be amended or waived (either generally or in a particular instance and either retroactively or prospectively) by a written instrument signed by the Borrower and the Required Lenders (and, if the rights or duties of the Administrative Agent are affected thereby, by the Administrative Agent); provided that no such amendment or waiver shall, unless signed by each Lender directly affected thereby (i) increase or decrease the Commitments of such Lender (except for a ratable decrease in the Commitments of all Lenders) or subject such Lender to any additional obligation; (ii) reduce the principal of or rate of interest on the Note of such Lender or any fees hereunder payable to or for the benefit of such Lender; (iii) postpone the date fixed for any payment of principal of or interest on the Note of such Lender or any fees hereunder payable to or for the benefit of such Lender; (iv) increase the Borrowing Base or decrease the amount by which the Borrowing Base is scheduled to decrease each month; (v) postpone the scheduled termination of such Lender’s Commitment; (vi) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Notes, or the number of Lenders, which shall be required for the Lenders or any of them to take any action under this Section or any other provision of this Agreement; (vii) amend this Section 9.1 or Section 7.9.2; or (viii) effect a release of any Guaranty.

9.1.2. Certain Guarantors might join in the execution of this Agreement or amendments hereto, but the signature or consent of such Guarantors shall not be required with respect to any future amendments to this Agreement.

9.2. Highest Lawful Interest Rate. The Administrative Agent, the Lenders, the Borrower and any other parties to the Loan Documents intend to contract in strict compliance with applicable usury law from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and provisions contained in the Loan Documents shall ever be construed to create a contract to pay, for the use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted to be charged by applicable law from time to time in effect, and the provisions of this Section 9.2 shall control over all other provisions of the Loan Documents which may be in conflict or apparent conflict herewith. Regardless of any provision contained in any of the Loan Documents, the Lenders shall never be entitled to receive, collect, or apply as interest on all or any part of the Loans, any amount in excess of the Highest Lawful Rate in effect from day to day, and, in the event any Lender ever receives, collects, or applies as interest any such excess, such amount which would be deemed excessive interest shall be deemed a partial prepayment of the principal of the Loans and treated hereunder as such; and, if the entire principal amount of the Loans owed to the Lenders is paid in full, any remaining excess shall be repaid to the Borrower. In determining whether the interest paid or payable, under any specific contingency, exceeds the Highest Lawful Rate in effect from

day to day, the Borrower and the Lenders shall, to the maximum extent permitted under applicable law, (i) characterize any nonprincipal payment as an expense, fee, or premium rather than as interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the Loans so that the interest rate is uniform throughout the entire term of the Loans; provided that, if the interest received by the Lenders for the actual period of existence thereof exceeds the Highest Lawful Rate in effect from day to day, the Lenders shall apply or refund to the Borrower the amount of such excess as provided in this Section, and, in such event, the Lenders shall not be subject to any penalties provided by any laws for contracting for, charging, taking, reserving, or receiving interest in excess of the Highest Lawful Rate in effect from day to day.

9.3. INDEMNITY.

9.3.1. Whether or not any Loans are ever funded or any letter of credit is ever issued hereunder, and in addition to any other indemnifications herein or in any other Loan Documents, the Borrower agrees to indemnify and defend and hold harmless on a current basis each Indemnified Party, from and against any and all liabilities, losses, damages, costs, interest, charges, counsel fees and other expenses and penalties of any kind which any of the Indemnified Parties may sustain or incur in connection with any investigative, administrative or judicial proceeding (whether or not any Indemnified Party shall be designated a party thereto) or otherwise by reason of or arising out of the execution and delivery of this Agreement or any of the other Loan Documents and/or the consummation of the transactions contemplated hereby or thereby. The indemnification provisions in this Section shall be enforceable regardless of whether the liability is based on past, present or future acts, claims or legal requirements (including any past, present or future bulk sales law, environmental law, fraudulent transfer act, occupational safety and health law, or products liability, securities or other legal requirement), AND REGARDLESS OF WHETHER ANY PERSON (INCLUDING THE PERSON FROM WHOM INDEMNIFICATION IS SOUGHT) ALLEGES OR PROVES THE SOLE, CONCURRENT, CONTRIBUTORY OR COMPARATIVE NEGLIGENCE OF THE PERSON SEEKING INDEMNIFICATION OR OF ANY OTHER INDEMNIFIED PARTY, OR THE SOLE OR CONCURRENT STRICT LIABILITY IMPOSED ON THE PERSON SEEKING INDEMNIFICATION OR ON ANY OTHER INDEMNIFIED PARTY, but not any of the foregoing in this Section arising from the gross negligence or willful misconduct on the part of the Indemnified Party seeking indemnification under this Section; with the foregoing indemnity surviving satisfaction of all obligations and the termination of this Agreement.

9.3.2. Any amount to be paid under Section 9.3 to the Administrative Agent or the Lenders shall be a demand obligation owing by the Borrower and if not paid within three Business Days of demand shall bear interest from the date of expenditure by the Administrative Agent or the Lenders until paid at a per annum rate equal to the Default Rate. The obligations of the Borrower under Section 9.3 shall survive payment of the Notes and the assignment of any right hereunder.

9.17.1. If on or after the date hereof, in the case of any Loan or any obligation to make Loans, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or its Lending

Installation) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall impose, modify or deem applicable any reserve (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System), special deposit, insurance assessment or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (or its Lending Installation) and the result of any of the foregoing is to reduce the amount of any sum received or receivable by such Lender (or its Lending Installation) under this Agreement or under its Notes with respect thereto, by an amount reasonably deemed by such Lender to be material, then, within 15 days after demand by such Lender (with a copy to the Administrative Agent), the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such increased cost or reduction.

9.17.2. If any Lender shall have reasonably determined that, after the date hereof, the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change in any such rule or regulation, or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on capital of such Lender as a consequence of such Lender’s obligations hereunder to a level below that which such Lender could have achieved but for such adoption, change, request or directive (taking into consideration its policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, within 15 days after demand by such Lender (with a copy to the Administrative Agent), the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction.

9.17.3. Each Lender will promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender to compensation pursuant to this Section and will designate a different Lending Installation if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole judgment of such Lender, be otherwise disadvantageous to such Lender. A certificate of any Lender claiming compensation under this Section and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods.

9.17.4. Notwithstanding anything in this Agreement to the contrary, (x) the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act and all requests, rules, guidelines or directives thereunder or issued in connection therewith and (y) all requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel III, shall in each case be deemed to be a “change in law,” regardless of the date enacted, adopted or issued.

9.18. Taxes.

9.18.1. For the purpose of this Section 9.18, the following terms have the following meanings:

“Taxes” means any and all present or future taxes, duties, levies, imposts, deductions, charges or withholdings with respect to any payment by the Borrower pursuant to this Agreement or under any Note, and all penalties and interest with respect thereto, excluding (i) in the case of each Lender and the Administrative Agent, taxes imposed on its income, and franchise or similar taxes imposed on it, by a jurisdiction under the laws of which such Lender or the Administrative Agent (as the case may be) is organized or in which its principal executive office is located, in which its Lending Installation is located or in which it would be subject to tax due to some connection other than that created by this Agreement and (ii) in the case of each Lender, any United States withholding tax at the time such Lender first becomes a party to this Agreement.

“Other Taxes” means any present or future stamp or documentary taxes and any other excise or property taxes, or similar charges or levies and all penalties and interest with respect thereto, which arise from the making of any payment pursuant to this Agreement or under any Note or from the execution or delivery of this Agreement or any Note.

9.18.2. Any and all payments by the Borrower to or for the account of any Lender or the Administrative Agent hereunder or under any Note shall be made without deduction for any Taxes or Other Taxes; provided that, if the Borrower shall be required by law to deduct any Taxes or Other Taxes from any such payments, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under Section 9.17) 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 been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law and (iv) the Borrower shall furnish to the Administrative Agent, at its address referred to in Article XIII, the original or a certified copy of a receipt evidencing payment thereof.

9.18.3. The Borrower agrees to indemnify each Lender and the Administrative Agent for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes on amounts payable under this Section) paid by such Lender or the Administrative Agent (as the case may be). This indemnification shall be paid within 15 days after such Lender or the Administrative Agent (as the case may be) makes appropriate demand therefor.

9.18.4. At least five Business Days prior to the first date on which interest or fees are payable hereunder for the account of any Lender, each Lender that is not incorporated under the laws of the United States of America, or a state thereof, agrees that it will deliver to each of the Borrower and the Administrative Agent two duly completed copies of United States Internal Revenue Service Form W-8 BEN or W-8 ECI or W-8 IMY or W-8 EXP or such other form as may be applicable and allowable under the Internal Revenue Code and the regulations

thereunder (collectively, a “Withholding Form”), certifying in either case that such Lender is entitled to receive payments under this Agreement and the Notes without deduction or withholding of any United States federal income taxes. Each Lender which so delivers a Withholding Form further undertakes to deliver to each of the Borrower and the Administrative Agent two additional copies of such form (or a successor form) on or before the date that such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent Withholding Form so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by the Borrower or the Administrative Agent, in each case certifying that such Lender is entitled to receive payments under this Agreement and the Notes without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such Withholding Forms inapplicable or which would prevent such Lender from duly completing and delivering any such Withholding Form with respect to it and such Lender advises the Borrower and the Administrative Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax.

9.18.5. For any period with respect to which a Lender has failed to provide the Borrower or the Administrative Agent with the appropriate form pursuant to Section 9.18.4 (unless such failure is due to a change in treaty, law or regulation occurring subsequent to the date on which such form originally was required to be provided), such Lender shall not be entitled to indemnification under Section 9.18.2 or 9.18.3 with respect to Taxes imposed by the United States; provided that if a Lender, which is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps (at the expense of such Lender) as such Lender shall reasonably request to assist such Lender to recover such Taxes.

9.18.6. If the Borrower is required to pay additional amounts to or for the account of any Lender pursuant to this Section, then such Lender will change the jurisdiction of its Lending Installation if, in the judgment of such Lender, such change (i) will eliminate or reduce any such additional payment which may thereafter accrue and (ii) is not otherwise disadvantageous to such Lender in its sole judgment.

9.18.7. The obligations of the Borrower under this Section 9.18 shall survive payment of the Notes, the satisfaction of all other Obligations and the termination of this Agreement.

The obligations of the Lenders under this Section 10.8 shall survive payment of the Obligations and termination of this Credit Agreement.

10.9. Rights as a Lender. The Administrative Agent shall have the same rights and powers hereunder and under any other Loan Document as any Lender and may exercise the same as though it were not the Administrative Agent, and the terms “Lender” and “Lenders” shall, unless the context otherwise indicates, include the Administrative Agent in its individual capacity.

other transaction, in addition to those contemplated by this Agreement or any other Loan Document, with the Borrower or any of its Affiliates unless the Borrower or such Affiliate is specifically restricted hereunder.

If no successor Administrative Agent shall have been so appointed by the Required Lenders within thirty days after the resigning Administrative Agent’s giving notice of its intention to resign, then the resigning Administrative Agent may appoint, on behalf of the Borrower and the Lenders, a successor Administrative Agent. If the Administrative Agent has resigned and no successor Administrative Agent has been appointed, the Lenders may perform all the duties of the Administrative Agent hereunder and the Borrower shall make all payments in respect of the Obligations to the applicable Lender and for all other purposes shall deal directly with the Lenders. No successor Administrative Agent shall be deemed to be appointed hereunder until such successor Administrative Agent has accepted the appointment. Any such successor Administrative Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning Administrative Agent. Upon the effectiveness of the resignation of the Administrative Agent, the resigning Administrative Agent shall be discharged from its duties and obligations hereunder and under the Loan Documents. After the effectiveness of the resignation of an Administrative Agent, the provisions of this Article X shall continue in effect for the benefit of such Administrative Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Administrative Agent hereunder and under the other Loan Documents.

10.12. Applicable Parties.

ARTICLE XI

SETOFF; RATABLE TREATMENTS

11.1. Setoff. In addition to, and without limitation of, any rights of the Lenders under applicable law, if any Event of Default occurs, any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other indebtedness at any time held or owing by any Lender or any Affiliate thereof to or for the credit or account of the Borrower may be offset and applied toward the payment of the Obligations, whether or not the Obligations, or any part hereof, shall then be due. Each Lender or Affiliate thereof making such an offset and application shall give the Borrower and the other Lenders written notice of such offset and application promptly after effecting it. To the extent that the Borrower has accounts, which in the style thereof as reflected in the Administrative Agent’s records are designated as royalty, joint interest owner or operator accounts, the foregoing right of set off shall not extend to funds in such accounts which belong to, or otherwise arise from payments to the Borrower for the account of, third-party royalty, joint interest owners, or operators.

11.2. Ratable Treatments; Adjustments.

11.2.1. Except to the extent otherwise expressly provided herein, (i) each borrowing pursuant to this Agreement shall be made from the Lenders pro rata in accordance with their respective Commitments, (ii) each payment by the Borrower of fees shall be made for the account of the Lenders pro rata in accordance with their respective Commitments, (iii) each payment of principal of Loans shall be made for the account of the Lenders pro rata in accordance with the principal balances of their respective Notes, and (iv) each payment of interest on the Notes 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 under the Notes.

11.2.2. The Administrative Agent shall distribute all payments received by it with respect to the Obligations promptly upon receipt in like funds as received. In the event that any payments made hereunder on the Obligations at any particular time are insufficient to satisfy in full the Obligations due and payable at such time, such payments shall be applied (i) first, to that portion of the Obligations consisting of fees and expenses then due and payable, (ii) second, to that portion of the Obligations consisting of accrued, unpaid interest then due and payable, (iii) third, to that portion of the Obligations consisting of principal then due and payable, and (iv) last, to any other Obligations.

11.2.3. If any Lender (for purposes of this Section, a “Benefitted Lender”) shall at any time receive any payment of all or part of its portion of the Obligations, or receive any Collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 8.1.4 or Section 8.1.5, or otherwise) in an amount greater than such Lender was entitled to receive pursuant to the terms hereof, such

Benefitted Lender shall purchase for cash from the other Lenders such portion of the Obligations of such other Lenders, or shall provide such other Lenders with the benefits of any such Collateral or the proceeds thereof, as shall be necessary to cause such Benefitted Lender to share the excess payment or benefits of such Collateral or proceeds with each of the Lenders according to the terms hereof. If all or any portion of such excess payment or benefits is thereafter recovered from such Benefitted Lender, such purchase shall be rescinded and the purchase price and benefits returned by each of the other Lenders, to the extent of such recovery, but without interest. The Borrower agrees that each such Lender so purchasing a portion of the Obligations of another Lender may exercise all rights of payment (including rights of set-off) with respect to such portion as fully as if such Lender were the direct holder of such portion. If any Lender ever receives, by voluntary payment, exercise of rights of set-off or banker’s lien, counterclaim, cross-action or otherwise, any funds of the Borrower to be applied to the Obligations, or receives any proceeds by realization on or with respect to any Collateral, all such funds and proceeds shall be forwarded immediately to the Administrative Agent for distribution in accordance with the terms of this Agreement.

The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Borrower, the Administrative Agent and the Lenders and their respective successors and assigns, except that (i) the Borrower shall not have any right to assign its rights or obligations under the Loan Documents and (ii) any assignment by any Lender must be made in compliance with Section 12.3. Notwithstanding clause (ii) of this Section 12.1, any Lender may at any time, without the consent of the Borrower or the Administrative Agent, assign all or any portion of its rights under this Agreement and its Note to a Federal Reserve Bank; provided, however, that no such assignment shall release the transferor Lender from its obligations hereunder. The Administrative Agent may treat the payee of any Note as the owner thereof for all purposes hereof unless and until such payee complies with Section 12.3 in the case of an assignment thereof or, in the case of any other transfer, a written notice of the transfer is filed with the Administrative Agent. Any Transferee of a Note agrees by acceptance thereof to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the holder of any Note, shall be conclusive and binding on any subsequent Transferee of such Note or of any Note or Notes issued in exchange therefor.

12.2. Participations; Voting Rights; Setoffs by Participants.

12.2.1. Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time sell to one or more banks or other entities (each a “Participant”) participating interests in any Loan owing to such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender under the Loan Documents. In the event of any such sale by a Lender of participating interests to a Participant, such Lender’s obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the holder of any such Note for all purposes under the Loan

Documents, all amounts payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interests, and the Borrower and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under the Loan Documents.

12.2.2. Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification or waiver with respect to any Loan, Letter of Credit or Commitment in which such Participant has an interest which forgives principal, interest or fees or reduces the interest rate or fees payable with respect to any such Loan, Letter of Credit or Commitment, postpones any date fixed for any regularly-scheduled payment of principal of, or interest or fees on, any such Loan, Letter of Credit or Commitment, releases any guarantor of any such Loan or Letter of Credit or releases any substantial portion of Collateral, if any, securing any such Loan or Letter of Credit.

12.2.3. The Borrower agrees that each Participant shall be deemed to have the right of setoff provided in Section 11.1 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents, and each Lender shall retain the right of setoff provided in Section 11.1 with respect to the amount of participating interests sold to each Participant. The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 11.1, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 11.2 as if each Participant were a Lender.

12.3. Assignments; Effective Date.

12.3.1. Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time assign to one or more banks or other entities (each a “Purchaser”) all or any part of its rights and obligations under the Loan Documents. Such assignment shall be in such form as may be agreed by the parties thereto and reasonably acceptable to the Administrative Agent (the “Assignment Agreement”) or in such other form as may be agreed to by the parties thereto. The consent of the Administrative Agent, which consent shall not be unreasonably withheld, shall be required prior to an assignment becoming effective with respect to a Purchaser which is not a Lender or an Affiliate thereof. Each such assignment shall (unless it is to a Lender or an Affiliate thereof or each of the Borrower and the Administrative Agent otherwise consents) be in an amount not less than the lesser of (i) $2,500,000 or (ii) the remaining amount of the assigning Lender’s Commitment (calculated as at the date of such assignment).

12.3.2. Upon (i) delivery to the Administrative Agent of a notice of assignment in form and substance reasonably satisfactory to the Administrative Agent (a “Notice of Assignment”), together with any consents required by Section 12.3.1, and (ii) payment of a $3,500 processing fee to the Administrative Agent for processing such assignment, such assignment shall become effective on the effective date specified in such Notice of Assignment. The Notice of Assignment shall contain a representation by the Purchaser to the effect that none of the consideration used to make the purchase of the Commitment and Loans

under the applicable Assignment Agreement are “plan assets” as defined under ERISA and that the rights and interests of the Purchaser in and under the Loan Documents will not be “plan assets” under ERISA. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to this Credit Agreement and any other Loan Document executed by the Lenders and shall have all the rights and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party hereto, and no further consent or action by the Borrower, the Lenders or the Administrative Agent shall be required to release the transferor Lender with respect to the percentage of the Aggregate Commitment and Loans assigned to such Purchaser. Upon the consummation of any assignment to a Purchaser pursuant to this Section 12.3.2, the transferor Lender, the Administrative Agent and the Borrower shall make appropriate arrangements so that replacement Notes are issued to such transferor Lender and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their Commitment, as adjusted pursuant to such assignment.

12.4. Dissemination of Information. The Borrower authorizes the Administrative Agent and each Lender to disclose to any Transferee and any prospective Transferee any and all information in the Administrative Agent’s or such Lender’s possession concerning the Borrower and its Affiliates.

12.5. Tax Treatment. If any interest in any Loan Document is transferred to any Transferee which is organized under the laws of any jurisdiction other than the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 9.19.4.
