The Administrative Agent shall promptly (i) notify Borrower of the final allocation of such increase in the Revolving Credit Commitment and the Increase Effective Date, and (ii) notify each Lender of its Revolving Credit Commitment as of the Increase Effective Date.

(v) As a condition precedent to such increase, Borrower shall deliver to the Administrative Agent a certificate of each Obligor dated as of the Increase Effective Date signed by a Responsible Officer of such Obligor (i) certifying and attaching the resolutions adopted by such Obligor approving or consenting to such increase, and (ii) in the case of Borrower, certifying that, before and after giving effect to such increase, (A) the representations and warranties contained in Article VII and the other Loan Documents are true and correct on and as of the Increase Effective Date, except to the extent that such representations and warranties specifically

refer to an earlier date, in which case they are true and correct as of such earlier date, and except that for purposes of this Section 2.03(b), the representations and warranties contained in Section 7.02 shall be deemed to refer to the most recent statements furnished pursuant to clauses (a) and (b), respectively, of Section 8.01, (B) no Default or Event of Default exists, and (C) no Material Adverse Effect shall have occurred. To the extent necessary to keep the outstanding Loans ratable with any revised Percentage Shares of the Lenders arising from any nonratable increase in the Revolving Credit Commitment under this Section, Borrower shall prepay Loans outstanding on the Increase Effective Date and/or Lenders shall make assignments pursuant to arrangements satisfactory to the Administrative Agent (provided, that in each case, Borrower shall pay any additional amounts required pursuant to Section 5.05).

(vi) This Section shall supersede any provisions in Sections 4.05 or 12.04 to the contrary.

(c) Reduction in Aggregate Revolving Credit Commitments. The Borrower shall have the right to reduce the amount of the Aggregate Revolving Credit Commitments at any time, or from time to time, upon not less than three (3) Business Days’ prior notice to the Administrative Agent (who shall promptly notify the Lenders) of each such reduction, which notice shall specify the effective date thereof and the amount of any such reduction (which shall not be less than $10,000,000 or any whole multiple of $10,000,000 in excess thereof; and no more than an amount by which the Aggregate Revolving Credit Commitments would be less than the aggregate outstanding principal amount of the Loans plus the LC Exposure, after giving effect to any concurrent prepayment pursuant to Section 2.07) and shall be irrevocable and effective only upon receipt by the Administrative Agent.

(d) Reduction in Aggregate Maximum Revolving Credit Amounts. The Borrower shall have the right to terminate or to reduce the amount of the Aggregate Maximum Revolving Credit Amounts at any time, or from time to time, upon not less than three (3) Business Days’ prior notice to the Administrative Agent (who shall promptly notify the Lenders) of each such termination or reduction, which notice shall specify the effective date thereof and the amount of any such reduction (which shall not be less than $10,000,000 or any whole multiple of $10,000,000 in excess thereof; and no more than an amount by which the Aggregate Maximum Revolving Credit Amounts would be less than the Aggregate Revolving Credit Commitments) and shall be irrevocable and effective only upon receipt by the Administrative Agent. The Aggregate Maximum Revolving Credit Amounts once terminated or reduced may not be reinstated.

Section 2.04 Fees.

(a) Commitment Fee. The Borrower shall pay to the Administrative Agent for the account of each Lender a commitment fee on the daily average unused amount of the Aggregate Revolving Credit Commitments up to, but excluding, the earlier of the date the Aggregate Revolving Credit Commitments are terminated or the Revolving Credit Termination Date at the Applicable Commitment Fee Rate. Accrued commitment fees shall be payable quarterly in arrears on each Quarterly Date and on the earlier of the date the Aggregate Revolving Credit Commitments are terminated or the Revolving Credit Termination Date. Borrower and Lenders acknowledge and agree that the unused commitment fees payable hereunder are bona fide unused commitment fees and are intended as reasonable compensation to Lenders for committing to make funds available to Borrower as described herein and for no other purposes.

(b) Letter of Credit Fees.

(i) The Borrower agrees to pay the Administrative Agent, for the account of each Lender, commissions for issuing the Letters of Credit on the daily average outstanding of the

maximum liability of the Issuing Bank existing from time to time under such Letter of Credit (calculated separately for each Letter of Credit) at the rate per annum equal to the Applicable Margin in effect from time to time for LIBOR Loans, provided that each Letter of Credit shall bear a minimum commission of $500 and further provided, during any period commencing on the date of an Event of Default until the same is paid in full or all Events of Default are cured and waived, equal to the Post-Default Rate. Each Letter of Credit shall be deemed to be outstanding up to the full face amount of the Letter of Credit until the Issuing Bank has received the canceled Letter of Credit or a written cancellation of the Letter of Credit from the beneficiary of such Letter of Credit in form and substance acceptable to the Issuing Bank, or for any reductions in the amount of the Letter of Credit (other than from a drawing), written notification from the beneficiary of such Letter of Credit. Such commissions are payable in advance at issuance of the Letter of Credit for the first year thereof and thereafter, quarterly in arrears on each Quarterly Date and upon cancellation or expiration of each such Letter of Credit.

(ii) The Borrower agrees to pay the Administrative Agent, for the account of the Issuing Bank, commissions for issuing the Letters of Credit (calculated separately for each Letter of Credit) equal to 0.125% of the face amount of each Letter of Credit, payable upon issuance of such Letter of Credit.

(c) Fee Letter. The Borrower shall pay to Administrative Agent for its account such other fees as are set forth in the Fee Letter on the dates specified therein to the extent not paid prior to the Closing Date.

Section 2.05 Several Obligations. The failure of any Lender to make any Loan to be made by it or to provide funds for disbursements or reimbursements under Letters of Credit on the date specified therefor shall not relieve any other Lender of its obligation to make its Loan or provide funds on such date, but no Lender shall be responsible for the failure of any other Lender to make a Loan to be made by such other Lender or to provide funds to be provided by such other Lender.

Section 2.06 Notes. The Loans made by each Lender shall be evidenced by a single promissory note of the Borrower in substantially the form of Exhibit A dated (i) the Closing Date or (ii) the effective date of an Assignment pursuant to Section 12.06(b), payable to the order of such Lender in a principal amount equal to its Maximum Revolving Credit Amount as originally in effect and otherwise duly completed and such substitute Notes as required by Section 12.06(b). The date, amount, Type, interest rate and Interest Period of each Loan made by each Lender, and all payments made on account of the principal thereof, shall be recorded by such Lender on its books for its Note, and, prior to any transfer may be endorsed by such Lender on the schedule attached to such Note or any continuation thereof or on any separate record maintained by such Lender. Failure to make any such notation or to attach a schedule shall not affect any Lender’s or the Borrower’s rights or obligations in respect of such Loans or affect the validity of such transfer by any Lender of its Note.

Section 2.07 Prepayments

(a) Voluntary Prepayments. The Borrower may prepay the Base Rate Loans upon not less than one (1) Business Day’s prior notice to the Administrative Agent (which shall promptly notify the Lenders), which notice shall specify the prepayment date (which shall be a Business Day) and the amount of the prepayment (which shall be at least $100,000 or the remaining aggregate principal balance outstanding on the Notes) and shall be irrevocable and effective only upon receipt by the Administrative Agent, provided that interest on the principal prepaid, accrued to the prepayment date, shall be paid on the prepayment date. The Borrower may prepay LIBOR Loans on the same conditions as for Base Rate Loans (except that prior notice to the Administrative Agent shall be not less than three (3) Business Days for LIBOR Loans) and in addition such prepayments of LIBOR Loans shall be subject to the terms of

Section 5.05 and shall be in an amount equal to all of the LIBOR Loans for the Interest Period prepaid. In the event of a voluntary prepayment pursuant to this Section 2.07(a), Borrower shall be entitled to reborrow such amounts pursuant to Section 2.01.

(b) Mandatory Prepayments. If a Borrowing Base Deficiency results from the redetermination of the Borrowing Base pursuant to Section 2.08(b) or (d), then the Borrower shall, within thirty (30) days notify Administrative Agent of Borrower’s election to, (i) prepay the Loans in two equal installments equal to one half of the aggregate principal amount sufficient to eliminate such Borrowing Base Deficiency, together with interest on the principal amount paid accrued to the date of each such prepayment due ninety (90) days and one hundred and eighty (180) days from the date of such redetermination, (ii) pledge, or cause any Subsidiary to pledge, additional unencumbered collateral of sufficient value and character (as determined by the Administrative Agent and the Lenders in their sole discretion) that when added to the existing collateral shall cause the Borrowing Base to equal or exceed the aggregate outstanding Loans plus the LC Exposure, or (iii) any combination of (i) and (ii) satisfactory to the Administrative Agent and all Lenders. If, because of LC Exposure, a Borrowing Base Deficiency remains after prepaying all of the Loans, the Borrower shall pay to the Administrative Agent on behalf of the Lenders an amount equal to such remaining Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.10(b).

(c) Generally. Prepayments permitted or required under this Section 2.07 shall be without premium or penalty, except as required under Section 5.05 for prepayment of LIBOR Loans. Any prepayments on the Loans may be reborrowed subject to the then effective Aggregate Revolving Credit Commitments.

Section 2.08 Borrowing Base.

(a) The Borrowing Base shall be determined in accordance with Section 2.08(b) by the Administrative Agent with the concurrence of the Lenders and is subject to redetermination in accordance with Section 2.08(d). Upon any redetermination of the Borrowing Base, such redetermination shall remain in effect until the next Redetermination Date. So long as any of the Commitments are in effect or any LC Exposure or Loans are outstanding hereunder, this facility shall be governed by the then effective Borrowing Base. During the period from and after the Closing Date until the first redetermination or reduction pursuant to Section 2.08, the amount of the Borrowing Base shall be $155,000,000 (the “Initial Borrowing Base”) which amount is comprised of the Oil and Gas Properties Collateral Value.

(b) Upon receipt of the reports required by Section 8.07 and such other reports, data and supplemental information as may from time to time be reasonably requested by the Administrative Agent (the “Engineering Reports”), the Borrowing Base shall be redetermined for each Borrowing Base Period and each such redetermination shall be effective as of the date set forth in such notice of redetermination delivered by the Administrative Agent to Borrower (the “Scheduled Redetermination Date”). The Oil and Gas Properties Collateral Value shall be determined based upon the loan collateral value assigned to the Mortgaged Properties. The Borrowing Base shall be equal to the sum of the Oil and Gas Properties Collateral Value and such other credit factors (including without limitation the assets, liabilities, cash flow, business, properties, prospects, management and ownership of the Borrower and its Subsidiaries) 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. 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 establish the redetermined Borrowing Base by unanimous agreement in the event of any increase in the Borrowing Base and by agreement of at least the Majority Lenders in the event of any redetermination to maintain or reduce the Borrowing Base. If a redetermined Borrowing Base is not approved by the Administrative Agent and the applicable Lenders within twenty (20) days of

the submission to the Lenders by the Administrative Agent of its recommended Borrowing Base, the Administrative Agent shall notify each Lender that the recommended Borrowing Base has not been approved and request that each Lender submit to the Administrative Agent within ten (10) days thereafter its proposed Borrowing Base. Promptly following the 10^th day after such request, the Administrative Agent shall determine the Borrowing Base for such Redetermination by calculating the highest Borrowing Base then acceptable to the Administrative Agent and a number of Lenders sufficient to constitute Majority Lenders (or all Lenders in the case of an increase). If the Borrower does not furnish the Engineering Reports 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 Revolving Credit Amount or otherwise.

(c) The Borrower shall have the right to reduce the amount of the Borrowing Base upon not less than thirty (30) days’ prior written notice to the Administrative Agent (who shall promptly notify the Lenders) of the reduction, which shall specify the effective date thereof and the amount of such reduction (which shall not be less than $1,000,000 or any whole multiple of $1,000,000 in excess thereof, no more than an amount which would cause a Borrowing Base Deficiency) and shall be irrevocable and effective only upon receipt by the Administrative Agent. The Borrowing Base once reduced at Borrower’s election may not be reinstated by Borrower, nor shall Lenders be obligated to determine the Borrowing Base at any subsequent Scheduled Redetermination Date or other Special Borrowing Base Determination at any particular amount, either in relation to the Borrowing Base prior or subsequent to any such optional reduction by Borrower.

(d) In addition to “Scheduled Redeterminations” pursuant to Section 2.08(b), the Borrower and the Majority Lenders may each request one (1) additional redetermination of the Borrowing Base during each Borrowing Base Period. In the event the Borrower or Majority Lenders request a “Special Borrowing Base Determination” pursuant to this Section 2.08(d), the Borrower shall deliver written notice of such request to the Administrative Agent which shall include: (i) Engineering Report(s) prepared as of a date not more than thirty (30) calendar days prior to the date of such request, and (ii) such other information as Administrative Agent and 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 Borrower notice of the redetermined Borrowing Base which shall state the effective date of the redetermination.

Section 2.09 Assumption of Risks. The Borrower assumes all risks of the acts or omissions of any beneficiary of any Letter of Credit or any transferee thereof with respect to its use of such Letter of Credit. Neither the Issuing Bank (except in the case of gross negligence or willful misconduct on the part of the Issuing Bank or any of its employees), its correspondents nor any Lender shall be responsible for the validity, sufficiency or genuineness of certificates or other documents or any endorsements thereon, even if such certificates or other documents should in fact prove to be invalid, insufficient, fraudulent or forged; for errors, omissions, interruptions or delays in transmissions or delivery of any messages by mail, telex, or otherwise, whether or not they be in code; for errors in translation or for errors in interpretation of technical terms; the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; the failure of any beneficiary or any transferee of any Letter of Credit to comply fully with conditions required in order to draw upon any Letter of Credit; or for any other consequences arising from causes beyond the Issuing Bank’s control or the control of the Issuing Bank’s correspondents. In addition, neither the Issuing Bank, the Administrative Agent nor any Lender shall be responsible for any error, neglect, or default of any of the Issuing Bank’s correspondents; and none of the above shall affect, impair or prevent the vesting of any of the Issuing Bank’s, the Administrative Agent’s or any Lender’s rights or powers hereunder or

under the Letter of Credit Agreements, all of which rights shall be cumulative. The Issuing Bank and its correspondents may accept certificates or other documents that appear on their face to be in order, without responsibility for further investigation of any matter contained therein regardless of any notice or information to the contrary. In furtherance and not in limitation of the foregoing provisions, the Borrower agrees that any action, inaction or omission taken or not taken by the Issuing Bank or by any correspondent for the Issuing Bank in good faith in connection with any Letter of Credit, or any related drafts, certificates, documents or instruments, shall be binding on the Borrower and shall not put the Issuing Bank or its correspondents under any resulting liability to the Borrower.

Section 2.10 Obligation to Reimburse and to Prepay.

(a) If a disbursement by the Issuing Bank is made under any Letter of Credit, the Borrower shall pay to the Administrative Agent within two (2) Business Days after notice of any such disbursement is received by the Borrower, the amount of each such disbursement made by the Issuing Bank under the Letter of Credit (if such payment is not sooner effected as may be required under this Section 2.10 or under other provisions of the Letter of Credit), together with interest on the amount disbursed from and including the date of disbursement until payment in full of such disbursed amount at a varying rate per annum equal to (i) the then applicable interest rate for Base Rate Loans through the second Business Day after notice of such disbursement is received by the Borrower and (ii) thereafter, the Post-Default Rate for Base Rate Loans (but in no event to exceed the Highest Lawful Rate) for the period from and including the third Business Day following the date of such disbursement to and including the date of repayment in full of such disbursed amount. The obligations of the Borrower under this Agreement with respect to each Letter of Credit shall be absolute, unconditional and irrevocable and shall be paid or performed strictly in accordance with the terms of this Agreement under all circumstances whatsoever, including, without limitation, but only to the fullest extent permitted by applicable law, the following circumstances: (i) any lack of validity or enforceability of this Agreement, any Letter of Credit or any of the Security Instruments; (ii) any amendment or waiver of (including any default), or any consent to departure from this Agreement (except to the extent permitted by any amendment or waiver), any Letter of Credit or any of the Security Instruments; (iii) the existence of any claim, set-off, defense or other rights which the Borrower may have at any time against the beneficiary of any Letter of Credit or any transferee of any Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Issuing Bank, the Administrative Agent, any Lender or any other Person, whether in connection with this Agreement, any Letter of Credit, the Security Instruments, the transactions contemplated hereby or any unrelated transaction; (iv) any statement, certificate, draft, notice or any other document presented under any Letter of Credit proves to have been forged, fraudulent, insufficient or invalid in any respect or any statement therein proves to have been untrue or inaccurate in any respect whatsoever; (v) payment by the Issuing Bank under any Letter of Credit against presentation of a draft certificate which appears on its face to comply, but does not comply, with the terms of such Letter of Credit; and (vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

Notwithstanding anything in this Agreement to the contrary, the Borrower will not be liable for payment or performance that results from the gross negligence or willful misconduct of the Issuing Bank, except (i) where the Borrower or any Subsidiary actually recovers the proceeds for itself or the Issuing Bank of any payment made by the Issuing Bank in connection with such gross negligence or willful misconduct or (ii) in cases where the Administrative Agent makes payment to the named beneficiary of a Letter of Credit.

(b) In the event of the occurrence of any Event of Default, a payment or prepayment pursuant to Section 2.07(b) or the maturity of the Notes, whether by acceleration or otherwise, an amount equal to the LC Exposure (or the excess in the case of Section 2.07(b)) shall be deemed to be forthwith due and owing by the Borrower to the Issuing Bank, the Administrative Agent and the Lenders as of the date of any such

occurrence; and the Borrower’s obligation to pay such amount shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower may now or hereafter have against any such beneficiary, the Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such payments shall be held by the Issuing Bank on behalf of the Lenders as cash collateral securing the LC Exposure in an account or accounts at the Principal Office; and the Borrower hereby grants to and by its deposit with the Administrative Agent grants to the Administrative Agent a security interest in such cash collateral. In the event of any such payment by the Borrower of amounts contingently owing under outstanding Letters of Credit and in the event that thereafter drafts or other demands for payment complying with the terms of such Letters of Credit are not made prior to the respective expiration dates thereof, the Administrative Agent agrees, if no Event of Default has occurred and is continuing or if no other amounts are outstanding under this Agreement, the Notes or the Security Instruments, to remit to the Borrower amounts for which the contingent obligations evidenced by the Letters of Credit have ceased.

(c) Each Lender severally and unconditionally agrees that it shall promptly reimburse the Issuing Bank an amount equal to such Lender’s Percentage Share of any disbursement made by the Issuing Bank under any Letter of Credit that is not reimbursed according to this Section 2.10.

(d) Notwithstanding anything to the contrary contained herein, if no Default exists and subject to availability under the Aggregate Revolving Credit Commitments (after reduction for LC Exposure), to the extent the Borrower has not reimbursed the Issuing Bank for any drawn upon Letter of Credit within one (1) Business Days after notice of such disbursement has been received by the Borrower, the amount of such Letter of Credit reimbursement obligation shall automatically be funded by the Lenders as a Loan hereunder and used by the Lenders to pay such Letter of Credit reimbursement obligation. If an Event of Default has occurred and is continuing, or if the funding of such Letter of Credit reimbursement obligation as a Loan would cause the aggregate amount of all Loans outstanding to exceed the Aggregate Revolving Credit Commitments (after reduction for LC Exposure), such Letter of Credit reimbursement obligation shall not be funded as a Loan, but instead shall accrue interest as provided in Section 2.10(a).

Section 2.11 Lending Offices. The Loans of each Type made by each Lender shall be made and maintained at such Lender’s Applicable Lending Office for Loans of such Type.

Section 3.02 Interest.

(a) Interest Rates. The Borrower will pay to the Administrative Agent, for the account of each Lender, interest on the unpaid principal amount of each Loan made by such Lender for the period commencing on the date such Loan is made to, but excluding, the date such Loan shall be paid in full, at the following rates per annum:

(i) if such a Loan is a Base Rate Loan, the Base Rate (as in effect from time to time) plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate; and

(ii) if such a Loan is a LIBOR Loan, for each Interest Period relating thereto, the Adjusted LIBOR for such Loan plus the Applicable Margin (as in effect from time to time), but in no event to exceed the Highest Lawful Rate.

(b) Post-Default Rate. Notwithstanding the foregoing, the Borrower will pay to the Administrative Agent, for the account of each Lender interest at the applicable Post-Default Rate on any Loan made by such Lender, and (to the fullest extent permitted by law) on any other amount payable by the Borrower hereunder, under any Loan Document or under any Note held by such Lender to or for account of such Lender, for the period commencing on the date of an Event of Default until the same is paid in full or all Events of Default are cured or waived.

(c) Due Dates. Accrued interest on Base Rate Loans shall be payable on each Quarterly Date commencing on January 1, 2007, and accrued interest on each LIBOR Loan shall be payable on the last day of the Interest Period therefor and, if such Interest Period is longer than three months, at three-month intervals following the first day of such Interest Period, except that interest payable at the Post-Default Rate shall be payable from time to time on demand and interest on any LIBOR Loan that is converted into a Base Rate Loan (pursuant to Section 5.04) shall be payable on the date of conversion (but only to the extent so converted). Any accrued and unpaid interest on the Loans on the Revolving Credit Termination Date shall be paid on such date.

(d) Determination of Rates. Promptly after the determination of any interest rate provided for herein or any change therein, the Administrative Agent shall notify the Lenders to which such interest is payable and the Borrower thereof.

ARTICLE IV

Payments; Pro Rata Treatment; Computations; Etc.

Section 4.01 Payments. Except to the extent otherwise provided herein, all payments of principal, interest and other amounts to be made by the Borrower under this Agreement, the Notes, Letters of Credit, and the Letter of Credit Agreements shall be made in Dollars, in immediately available funds, to the Administrative Agent at such account as the Administrative Agent shall specify by notice to the Borrower from time to time, not later than 12:00 p.m. Charlotte, North Carolina time on the date on which such payments shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day). Such payments shall be made without (to the fullest extent permitted by applicable law) defense, set-off or counterclaim. Each payment received by the Administrative Agent under this Agreement or any Note for account of a Lender shall be paid promptly to such Lender in immediately available funds. Except as otherwise provided in the definition of “Interest Period”, if the due date of any payment under this Agreement or any Note would otherwise fall on a day which is not a Business Day such date shall be extended to the next succeeding Business Day and interest shall be payable for any principal so extended for the period of such extension. At the time of each payment to the Administrative Agent of any principal of or interest on any borrowing, the Borrower shall notify the Administrative Agent of the Loans to which such payment shall apply. In the absence of such notice the Administrative Agent may specify the Loans to which such payment shall apply, but to the extent possible such payment or prepayment will be applied first to the Loans comprised of Base Rate Loans.

Section 4.02 Pro Rata Treatment. Except to the extent otherwise provided herein each Lender agrees that: (i) each borrowing from the Lenders under Section 2.01 and each continuation and

conversion under Section 2.02 shall be made from the Lenders pro rata in accordance with their Percentage Share, each payment of fees under Sections 2.04(a) and 2.04(b)(i) shall be made for account of the Lenders pro rata in accordance with their Percentage Share, and each termination or reduction of the amount of the Aggregate Revolving Credit Commitments or the Aggregate Maximum Revolving Credit Amounts under Section 2.03 shall be applied to the Commitment of each Lender, pro rata according to the amounts of its respective Commitment; (ii) each payment of principal of Loans by the Borrower shall be made for account of the Lenders pro rata in accordance with the respective unpaid principal amount of the Loans held by the Lenders; and (iii) each payment of interest on Loans by the Borrower shall be made for account of the Lenders pro rata in accordance with the amounts of interest due and payable to the respective Lenders; and (iv) each reimbursement by the Borrower of disbursements under Letters of Credit shall be made for account of the Issuing Bank or, if funded by the Lenders, pro rata for the account of the Lenders, in accordance with the amounts of reimbursement obligations due and payable to each respective Lender.

Section 4.03 Computations. Interest on LIBOR Loans and fees shall be computed on the basis of a year of 360 days and actual days elapsed (including the first day but excluding the last day) occurring in the period for which such interest is payable, unless such calculation would exceed the Highest Lawful Rate, in which case interest shall be calculated on the per annum basis of a year of 365 or 366 days, as the case may be. Interest on Base Rate Loans shall be computed on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed (including the first day but excluding the last day) occurring in the period for which such interest is payable.

Section 4.04 Non-receipt of Funds by the Administrative Agent. Unless the Administrative Agent shall have been notified by a Lender or the Borrower prior to the date on which such notifying party is scheduled to make payment to the Administrative Agent (in the case of a Lender) of the proceeds of a Loan or a payment under a Letter of Credit to be made by it hereunder or (in the case of the Borrower) a payment to the Administrative Agent for account of one or more of the Lenders hereunder (such payment being herein called the “Required Payment”), which notice shall be effective upon receipt, that it does not intend to make the Required Payment to the Administrative Agent, the Administrative Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be required to), make the amount thereof available to the intended recipient(s) on such date and, if such Lender or the Borrower (as the case may be) has not in fact made the Required Payment to the Administrative Agent, the recipient(s) of such payment shall, on demand, repay to the Administrative Agent 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, but excluding, the date the Administrative Agent recovers such amount at a rate per annum which, for any Lender as recipient, will be equal to the Federal Funds Rate, and for the Borrower as recipient, will be equal to the Base Rate plus the Applicable Margin.

Section 4.05 Set-off, Sharing of Payments, Etc.

(a) The Borrower agrees that, in addition to (and without limitation of) any right of set-off, bankers’ lien or counterclaim a Lender may otherwise have, each Lender shall have the right and be entitled (after consultation with the Administrative Agent), at its option, to offset balances held by it or by any of its Affiliates for account of the Borrower or any Subsidiary at any of its offices, in Dollars or in any other currency, against any principal of or interest on any of such Lender’s Loans, or any other amount payable to such Lender hereunder, which is not paid when due (regardless of whether such balances are then due to the Borrower), in which case it shall promptly notify the Borrower and the Administrative Agent thereof, provided that such Lender’s failure to give such notice shall not affect the validity thereof.

(b) If any Lender shall obtain payment of any principal of or interest on any Loan made by it to the Borrower under this Agreement (or reimbursement as to any Letter of Credit) through the exercise of any right of set-off, banker’s lien or counterclaim or similar right or otherwise, and, as a result of such payment, such Lender shall have received a greater percentage of the principal or interest (or reimbursement) then due hereunder by the Borrower to such Lender than the percentage received by any other Lenders, it shall promptly (i) notify the Administrative Agent and each other Lender thereof and (ii) purchase from such other Lenders participations in (or, if and to the extent specified by such Lender, direct interests in) the Loans (or participations in Letters of Credit) made by such other Lenders (or in interest due thereon, as the case may be) in such amounts, and make such other adjustments from time to time as shall be equitable, to the end that all the Lenders shall share the benefit of such excess payment (net of any expenses which may be incurred by such Lender in obtaining or preserving such excess payment) pro rata in accordance with the unpaid principal and/or interest on the Loans held by each of the Lenders (or reimbursements of Letters of Credit). To such end all the Lenders shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. The Borrower agrees that any Lender so purchasing a participation (or direct interest) in the Loans made by other Lenders (or in interest due thereon, as the case may be) may exercise all rights of set-off, banker’s lien, counterclaim or similar rights with respect to such participation as fully as if such Lender were a direct holder of Loans (or Letters of Credit) in the amount of such participation. Nothing contained herein shall require any Lender to exercise any such right or shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of the Borrower. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a set-off to which this Section 4.05 applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders entitled under this Section 4.05 to share the benefits of any recovery on such secured claim.

Section 4.06 Taxes.

(a) Payments Free and Clear. Any and all payments by the Borrower hereunder shall be made, in accordance with Section 4.01, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender, the Issuing Bank and the Administrative Agent, taxes imposed on its income, and franchise or similar taxes imposed on it, by (i) any jurisdiction (or political subdivision thereof) of which the Administrative Agent, the Issuing Bank or such Lender, as the case may be, is a citizen or resident or in which such Lender has an Applicable Lending Office, (ii) the jurisdiction (or any political subdivision thereof) in which the Administrative Agent, the Issuing Bank or such Lender is organized, or (iii) any jurisdiction (or political subdivision thereof) in which such Lender, the Issuing Bank or the Administrative Agent is presently doing business which taxes are imposed solely as a result of doing business in such jurisdiction (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to the Lenders, the Issuing Bank or the Administrative Agent (i) the sum payable shall be increased by the amount necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 4.06) such Lender, the Issuing Bank or the Administrative Agent (as the case may be) shall receive an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxing authority or other Governmental Authority in accordance with applicable law.

(b) Other Taxes. In addition, to the fullest extent permitted by applicable law, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or from the execution, delivery or

registration of, or otherwise with respect to, this Agreement, any Assignment or any Security Instrument (hereinafter referred to as “Other Taxes”).

(c) INDEMNIFICATION. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE BORROWER WILL INDEMNIFY EACH LENDER AND THE ISSUING BANK AND THE ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF TAXES AND OTHER TAXES (INCLUDING, BUT NOT LIMITED TO, ANY TAXES OR OTHER TAXES IMPOSED BY ANY GOVERNMENTAL AUTHORITY ON AMOUNTS PAYABLE UNDER THIS SECTION 4.06) PAID BY SUCH LENDER, THE ISSUING BANK OR THE ADMINISTRATIVE AGENT (ON THEIR BEHALF OR ON BEHALF OF ANY LENDER), AS THE CASE MAY BE, AND ANY LIABILITY (INCLUDING PENALTIES, INTEREST AND EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY ASSERTED UNLESS THE PAYMENT OF SUCH TAXES WAS NOT CORRECTLY OR LEGALLY ASSERTED AND SUCH LENDER’S PAYMENT OF SUCH TAXES OR OTHER TAXES WAS THE RESULT OF ITS GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. ANY PAYMENT PURSUANT TO SUCH INDEMNIFICATION SHALL BE MADE WITHIN THIRTY (30) DAYS AFTER THE DATE ANY LENDER, THE ISSUING BANK OR THE ADMINISTRATIVE AGENT, AS THE CASE MAY BE, MAKES WRITTEN DEMAND THEREFOR. IF ANY LENDER, ISSUING BANK OR THE ADMINISTRATIVE AGENT RECEIVES A REFUND OR CREDIT IN RESPECT OF ANY TAXES OR OTHER TAXES FOR WHICH SUCH LENDER, ISSUING BANK OR THE ADMINISTRATIVE AGENT HAS RECEIVED PAYMENT FROM THE BORROWER IT SHALL PROMPTLY NOTIFY THE BORROWER OF SUCH REFUND OR CREDIT AND SHALL, IF NO DEFAULT HAS OCCURRED AND IS CONTINUING, WITHIN THIRTY (30) DAYS AFTER RECEIPT OF A REQUEST BY THE BORROWER (OR PROMPTLY UPON RECEIPT, IF THE BORROWER HAS REQUESTED APPLICATION FOR SUCH REFUND OR CREDIT PURSUANT HERETO), PAY AN AMOUNT EQUAL TO SUCH REFUND OR CREDIT TO THE BORROWER WITHOUT INTEREST (BUT WITH ANY INTEREST SO REFUNDED OR CREDITED) PROVIDED THAT THE BORROWER, UPON THE REQUEST OF SUCH LENDER, THE ISSUING BANK OR THE ADMINISTRATIVE AGENT, AGREES TO RETURN SUCH REFUND OR CREDIT (PLUS PENALTIES, INTEREST OR OTHER CHARGES) TO SUCH LENDER OR THE ADMINISTRATIVE AGENT IN THE EVENT SUCH LENDER OR THE ADMINISTRATIVE AGENT IS REQUIRED TO REPAY SUCH REFUND OR CREDIT.

(d) Lender Representations.

(i) Each Lender represents that it is either (1) a banking association or corporation organized under the laws of the United States of America or any state thereof or (2) it is entitled to complete exemption from United States withholding tax imposed on or with respect to any payments, including fees, to be made to it pursuant to this Agreement (A) under an applicable provision of a tax convention to which the United States of America is a party or (B) because it is acting through a branch, agency or office in the United States of America and any payment to be received by it hereunder is effectively connected with a trade or business in the United States of America. Each Lender that is not a banking association or corporation organized under the laws of the United States of America or any state thereof agrees to provide to the Borrower and the Administrative Agent on the Closing Date, or on the date of its delivery of the Assignment pursuant to which it becomes a Lender, and at such other times as required by United States law or as the Borrower or the Administrative Agent shall reasonably request, two accurate and complete original signed copies of either (A) Internal Revenue Service Form W-8ECI (or successor form) certifying that all payments to be made to it hereunder will be effectively connected to a United States trade or business (the “Form W-8ECI Certification”) or (B) Internal Revenue Service Form W-8BEN (or successor form) certifying that it is entitled to the benefit of

a provision of a tax convention to which the United States of America is a party which completely exempts from United States withholding tax all payments to be made to it hereunder (the “Form W-8BEN Certification”). In addition, each Lender agrees that if it previously filed a Form W-8ECI Certification, it will deliver to the Borrower and the Administrative Agent a new Form W-8ECI Certification prior to the first payment date occurring in each of its subsequent taxable years; and if it previously filed a Form W8BEN Certification, it will deliver to the Borrower and the Administrative Agent a new certification prior to the first payment date falling in the third year following the previous filing of such certification. Each Lender also agrees to deliver to the Borrower and the Administrative Agent such other or supplemental forms as may at any time be required as a result of changes in applicable law or regulation in order to confirm or maintain in effect its entitlement to exemption from United States withholding tax on any payments hereunder, provided that the circumstances of such Lender at the relevant time and applicable laws permit it to do so. If a Lender determines, as a result of any change in either (i) a Governmental Requirement or (ii) its circumstances, that it is unable to submit any form or certificate that it is obligated to submit pursuant to this Section 4.06, or that it is required to withdraw or cancel any such form or certificate previously submitted, it shall promptly notify the Borrower and the Administrative Agent of such fact. If a Lender is organized under the laws of a jurisdiction outside the United States of America, unless the Borrower and the Administrative Agent have received a Form W-8BEN Certification or Form W-8ECI Certification satisfactory to them indicating that all payments to be made to such Lender hereunder are not subject to United States withholding tax, the Borrower shall withhold taxes from such payments at the applicable statutory rate. Each Lender agrees to indemnify and hold harmless the Borrower or Administrative Agent, as applicable, from any United States taxes, penalties, interest and other expenses, costs and losses incurred or payable by (i) the Administrative Agent as a result of such Lender’s failure to submit any form or certificate that it is required to provide pursuant to this Section 4.06 or (ii) the Borrower or the Administrative Agent as a result of their reliance on any such form or certificate which such Lender has provided to them pursuant to this Section 4.06.

(ii) For any period with respect to which a Lender has failed to provide the Borrower with the form required pursuant to this Section 4.06, if any (other than if such failure is due to a change in a Governmental Requirement occurring subsequent to the date on which a form originally was required to be provided), such Lender shall not be entitled to indemnification under Section 4.06 with respect to taxes imposed by the United States which taxes would not have been imposed but for such failure to provide such forms; provided, however, 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 as such Lender shall reasonably request to assist such Lender to recover such taxes.

(iii) Any Lender claiming any additional amounts payable pursuant to this Section 4.06 shall use reasonable efforts (consistent with legal and regulatory restrictions) to file any certificate or document requested by the Borrower or the Administrative Agent or to change the jurisdiction of its Applicable Lending Office or to contest any tax imposed if the making of such a filing or change or contesting such tax would avoid the need for or reduce the amount of any such additional amounts that may thereafter accrue and would not, in the sole determination of such Lender, be otherwise disadvantageous to such Lender.

ARTICLE V

Capital Adequacy

Section 5.01 Additional Costs.

(a) LIBOR Regulations, etc. The Borrower shall pay directly to each Lender from time to time such amounts as such Lender may determine to be necessary to compensate such Lender for any costs which it determines are attributable to its making or maintaining of any LIBOR Loans or issuing or participating in Letters of Credit hereunder or its obligation to make any LIBOR Loans or issue or participate in any Letters of Credit hereunder, or any reduction in any amount receivable by such Lender hereunder in respect of any of such LIBOR Loans, Letters of Credit (such increases in costs and reductions in amounts receivable being herein called “Additional Costs”), resulting from any Regulatory Change which: (i) changes the basis of taxation of any amounts payable to such Lender under this Agreement or any Note in respect of any of such LIBOR Loans or Letters of Credit (other than taxes imposed on the overall net income of such Lender or of its Applicable Lending Office for any of such LIBOR Loans by the jurisdiction in which such Lender has its principal office or Applicable Lending Office); or (ii) imposes or modifies any reserve, special deposit, minimum capital, capital ratio or similar requirements relating to any extensions of credit or other assets of, or any deposits with or other liabilities of such Lender, or the Commitment or Loans of such Lender or the London interbank market; or (iii) imposes any other condition affecting this Agreement or any Note (or any of such extensions of credit or liabilities) or such Lender’s Commitment or Loans. Each Lender will notify the Administrative Agent and the Borrower of any event occurring after the Closing Date which will entitle such Lender to compensation pursuant to this Section 5.01(a) as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, and will designate a different Applicable Lending Office for the Loans of such Lender affected by such event if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, be disadvantageous to such Lender, provided that such Lender shall have no obligation to so designate an Applicable Lending Office located in the United States. If any Lender requests compensation from the Borrower under this Section 5.01(a), the Borrower may, by notice to such Lender, suspend the obligation of such Lender to make additional Loans of the Type with respect to which such compensation is requested until the Regulatory Change giving rise to such request ceases to be in effect (in which case the provisions of Section 5.04 shall be applicable).

(b) Regulatory Change. Without limiting the effect of the provisions of Section 5.01(a), in the event that at any time (by reason of any Regulatory Change or any other circumstances arising after the Closing Date affecting (A) any Lender, (B) the London interbank market or (C) such Lender’s position in such market), the Adjusted LIBOR, as determined in good faith by such Lender, will not adequately and fairly reflect the cost to such Lender of funding its LIBOR Loans, then, if such Lender so elects, by notice to the Borrower and the Administrative Agent, the obligation of such Lender to make additional LIBOR Loans shall be suspended until such Regulatory Change or other circumstances ceases to be in effect (in which case the provisions of Section 5.04 shall be applicable).

(c) Capital Adequacy. Without limiting the effect of the foregoing provisions of this Section 5.01 (but without duplication), the Borrower shall pay directly to any Lender from time to time on request such amounts as such Lender may reasonably determine to be necessary to compensate such Lender or its parent or holding company for any costs which it determines are attributable to the maintenance by such Lender or its parent or holding company (or any Applicable Lending Office), pursuant to any Governmental Requirement following any Regulatory Change, of capital in respect of its Commitment, its Note, or its Loans or any interest held by it in any Letter of Credit, such compensation to include, without limitation, an amount equal to any reduction of the rate of return on assets or equity of such Lender or its parent or holding company (or any Applicable Lending Office) to a level below that which such Lender or its parent or holding company (or any Applicable Lending Office) could have achieved but for such Governmental Requirement. Such Lender will notify the Borrower that it is entitled to compensation pursuant to this Section 5.01(c) as promptly as practicable after it determines to request such compensation.

(d) Compensation Procedure. Any Lender notifying the Borrower of the incurrence of Additional Costs under this Section 5.01 shall in such notice to the Borrower and the Administrative Agent set forth in reasonable detail the basis and amount of its request for compensation. Determinations and allocations by each Lender for purposes of this Section 5.01 of the effect of any Regulatory Change pursuant to Section 5.01(a) or (b), or of the effect of capital maintained pursuant to Section 5.01(c), on its costs or rate of return of maintaining Loans or its obligation to make Loans or issue Letters of Credit, or on amounts receivable by it in respect of Loans or Letters of Credit, and of the amounts required to compensate such Lender under this Section 5.01, shall be conclusive and binding for all purposes, provided that such determinations and allocations are made on a reasonable basis. Any request for additional compensation under this Section 5.01 shall be paid by the Borrower within thirty (30) days of the receipt by the Borrower of the notice described in this Section 5.01(d).

Section 5.02 Limitation on LIBOR Loans. Anything herein to the contrary notwithstanding, if, on or prior to the determination of any Adjusted LIBOR for any Interest Period:

(i) the Administrative Agent determines (which determination shall be conclusive, absent manifest error) that quotations of interest rates for the relevant deposits referred to in the definition of “Adjusted LIBOR” in Section 1.02 are not being provided in the relevant amounts or for the relevant maturities for purposes of determining rates of interest for LIBOR Loans as provided herein; or

(ii) the Administrative Agent determines (which determination shall be conclusive, absent manifest error) that the relevant rates of interest referred to in the definition of “Adjusted LIBOR” in Section 1.02 upon the basis of which the rate of interest for LIBOR Loans for such Interest Period is to be determined are not sufficient to adequately cover the cost to the Lenders of making or maintaining LIBOR Loans; then the Administrative Agent shall give the Borrower prompt notice thereof, and so long as such condition remains in effect, the Lenders shall be under no obligation to make additional LIBOR Loans.

Section 5.03 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 LIBOR Loans hereunder, then such Lender shall promptly notify the Borrower thereof and such Lender’s obligation to make LIBOR Loans shall be suspended until such time as such Lender may again make and maintain LIBOR Loans (in which case the provisions of Section 5.04 shall be applicable).

Section 5.04 Base Rate Loans Pursuant to Sections 5.01, 5.02 and 5.03. If the obligation of any Lender to make LIBOR Loans shall be suspended pursuant to Sections 5.01, 5.02 or 5.03 (“Affected Loans”), all Affected Loans which would otherwise be made by such Lender shall be made instead as Base Rate Loans (and, if an event referred to in Section 5.01(b) or Section 5.03 has occurred and such Lender so requests by notice to the Borrower, all Affected Loans of such Lender then outstanding shall be automatically converted into Base Rate 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) Base Rate Loans, all payments of principal which would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its Base Rate Loans.

Section 5.05 Compensation. The Borrower shall pay to each Lender within thirty (30) days of receipt of written request of such Lender (which request shall set forth, in reasonable detail, the basis for requesting such amounts and which shall be conclusive and binding for all purposes provided that such determinations are made on a reasonable basis), such amount or amounts as shall compensate it for any loss, cost, expense or liability which such Lender determines are attributable to:

(i) any payment, prepayment or conversion of a LIBOR Loan properly made by such Lender or the Borrower for any reason (including, without limitation, the acceleration of the Loans pursuant to Section 10.01) on a date other than the last day of the Interest Period for such Loan; or

(ii) any failure by the Borrower for any reason (including but not limited to, the failure of any of the conditions precedent specified in Article VI to be satisfied) to borrow, continue or convert a LIBOR Loan from such Lender on the date for such borrowing, continuation or conversion specified in the relevant notice given pursuant to Section 2.02(c).

Without limiting the effect of the preceding sentence, such compensation shall include an amount equal to the excess, if any, of (i) the amount of interest which would have accrued on the principal amount so paid, prepaid or converted or not borrowed for the period from the date of such payment, prepayment or conversion or failure to borrow to the last day of the Interest Period for such Loan (or, in the case of a failure to borrow, the Interest Period for such Loan which would have commenced on the date specified for such borrowing) at the applicable rate of interest for such Loan provided for herein over (ii) the interest component of the amount such Lender would have bid in the London interbank market for Dollar deposits of leading banks in amounts comparable to such principal amount and with maturities comparable to such period (as reasonably determined by such Lender).

Each of the Obligors represents and warrants to the Administrative Agent and the Lenders that (each representation and warranty herein is given as of the Closing Date and shall be deemed repeated and reaffirmed on the dates of each borrowing and issuance, renewal, extension or reissuance of a Letter of Credit as provided in Section 6.02):

The Financial Statements are complete and correct and fairly present the consolidated financial condition of the Borrower and its Consolidated Subsidiaries as of the applicable dates and the results of its operations for the applicable period, all in accordance with GAAP, as applied on a consistent basis (subject, in the case of the interim financial statements, to normal year-end adjustments).

Section 7.05 Authority. Each Obligor has all necessary corporate, limited liability company, or partnership power and authority, as applicable, to execute, deliver and perform its obligations under the Loan Documents to which it is a party; and the execution, delivery and performance by each Obligor of the Loan Documents to which it is a party, have been duly authorized by all necessary corporate, limited liability company, or partnership action, as applicable, on its part; and the Loan Documents constitute the legal, valid and binding obligations of each Obligor, enforceable in accordance with their terms.

Neither the Borrower nor any other Obligor is engaged principally, or as one of its important activities, in the business of extending credit for the purpose, whether immediate, incidental or ultimate, of buying or carrying margin stock (within the meaning of Regulation T, U or X of the Board of Governors of the Federal Reserve System) and no part of the proceeds of any Loan hereunder will be used to buy or carry any margin stock.

Section 7.08 ERISA.

(b) Each Plan is, and has been, maintained in substantial compliance with ERISA and, where applicable, the Code.

(d) No contingent obligations remain due to the termination of any Plan (other than a defined contribution plan) or any trust created under any such Plan since September 2, 1974. The only Plan that has been terminated was for The Atlas Group, Inc. No liability to the PBGC (other than for the payment of current premiums which are not past due) by any Obligor, any Subsidiary or any ERISA Affiliate has been or is expected by any Obligor, any Subsidiary or any ERISA Affiliate to be incurred with respect to any Plan. No ERISA Event with respect to any Plan has occurred.

(e) Full payment when due has been made of all amounts which any Obligor, any Subsidiary or any ERISA Affiliate is required under the terms of each Plan or applicable law to have paid as contributions to such Plan, and no accumulated funding deficiency (as defined in section 302 of ERISA and section 412 of the Code), whether or not waived, exists with respect to any Plan.

(f) The actuarial present value of the benefit liabilities under each Plan which is subject to Title IV of ERISA does not, as of the end of each Obligor’s most recently ended fiscal year, exceed the current value of the assets (computed on a plan termination basis in accordance with Title IV of ERISA) of such Plan allocable to such benefit liabilities. The term “actuarial present value of the benefit liabilities” shall have the meaning specified in section 4041 of ERISA.

(g) None of the Obligors, any Subsidiary or any ERISA Affiliate sponsors, maintains, or contributes to an employee welfare benefit plan, as defined in section 3(l) of ERISA, including, without limitation, any such plan maintained to provide benefits to former employees of such entities, that may not be terminated by an Obligor, a Subsidiary or any ERISA Affiliate in its sole discretion at any time without any material liability.

(h) None of the Obligors, any Subsidiary or any ERISA Affiliate sponsors, maintains or contributes to, or has at any time in the preceding six calendar years, sponsored, maintained or contributed to, any Multiemployer Plan.

(i) None of the Obligors, any Subsidiary or any ERISA Affiliate is required to provide security under section 401 (a)(29) of the Code due to a Plan amendment that results in an increase in current liability for the Plan.

Section 7.09 Taxes. Each Obligor and its Subsidiaries has filed all United States federal income tax returns and all other tax returns which are required to be filed by them, or otherwise obtained appropriate extensions to file, and have paid all material taxes due pursuant to such returns or pursuant to any assessment received by any Obligor or any Subsidiary except such taxes that are being contested in good faith by appropriate proceedings and for which such Obligor, as applicable, has set aside on its books adequate reserves in accordance with GAAP. The charges, accruals and reserves on the books of each Obligor and its Subsidiaries in respect of taxes and other governmental charges are, in the opinion of the Borrower, adequate. No tax lien has been filed and, to the knowledge of the Obligors, no claim is being asserted with respect to any such tax, fee or other charge.

(a) Each of the Obligors has good and marketable title to its Oil and Gas Properties, free and clear of all Liens, except Excepted Liens. After giving full effect to the Excepted Liens, each Obligor owns either directly in its own name, or indirectly through its percentage ownership interest in the Partnerships, the net interests in production attributable to its Hydrocarbon Interests reflected in the most recently delivered Ownership Report and the ownership of such Oil and Gas Properties shall not in any material respect obligate such Obligor to bear the costs and expenses relating to the maintenance, development and operations of each such Oil and Gas Property in an amount in excess of the working interest of each Oil and Gas Property set forth in the most recently delivered Reserve Report; provided that to the extent an Obligor is a general partner of a Partnership, such Obligor is liable for all of the costs and expenses attributable to such Partnership’s interest, but only entitled to such Obligor’s percentage interest in such Partnership’s net revenues. In the event an Obligor, as a general partner, pays more than its partnership share of such Partnership’s costs and expenses, such Obligor is entitled to reimbursement of such excess amount out of the future income of such Partnership. All information contained in the most recently delivered Ownership Report and Reserve Report is true and correct in all material respects as of the date thereof.

(b) All leases and agreements necessary for the conduct of the business of the Obligors are valid and subsisting, in full force and effect and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such lease or leases, which would affect in any material respect the conduct of the business of any Obligor.

(c) The rights, Properties and other assets presently owned, leased or licensed by the Obligors including, without limitation, all easements and rights of way, include all rights, Properties and other assets necessary to permit each Obligor to conduct its business in all material respects in the same manner as its business has been conducted prior to the Closing Date.

information was prepared in good faith based on assumptions believed to be reasonable at the time. There is no fact peculiar to any Obligor which has a Material Adverse Effect or in the future is reasonably likely to have a Material Adverse Effect and which has not been set forth in this Agreement or the other documents, certificates and statements furnished to the Administrative Agent by or on behalf of the Obligors prior to, or on, the Closing Date in connection with the transactions contemplated hereby.

The Borrower and each of its Subsidiaries hereby ratifies and confirms all that Administrative Agent shall lawfully do or cause to be done by virtue of this power of attorney and the rights granted with respect to such power of attorney. This power of attorney is coupled with the interest of Administrative Agent in the Collateral, shall commence and be in full force and effect as of the Closing Date and shall remain in full force and effect and shall be irrevocable so long as any Obligation remains outstanding or unpaid or any Commitment exists. The powers conferred on Administrative Agent by this appointment are solely to protect the interests of Administrative Agent and each of the Lenders under the Loan Documents and shall not impose any duty upon Administrative Agent to exercise any such powers. Administrative Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers and shall not

be responsible to Borrower, its Subsidiaries, or any other Person for any act or failure to act with respect to such powers, except for gross negligence or willful misconduct.

(iii) Until such time as Administrative Agent shall notify Borrower and its Subsidiaries to the contrary, Borrower and its Subsidiaries shall be entitled to receive from the purchasers or disbursers of production all such proceeds of runs, subject however to the liens created under the Security Instruments. Upon the occurrence and during the continuance of a Default or such other time as Administrative Agent shall in its discretion so elect, Administrative Agent may deliver to the addressees the letters-in-lieu described in Subsection 8.09(d)(i) above and may exercise all rights and remedies granted under the Security Instruments, including the right to obtain possession of all proceeds of runs then held by Borrower and its Subsidiaries or to receive directly from the purchaser or disburser of production all other proceeds of runs.

(iv) In no case shall any failure, whether purposed or inadvertent, by Administrative Agent to collect directly any such proceeds of runs constitute in any way a waiver, remission or release of any of its rights under the Security Instruments, nor shall any release of any other proceeds of runs or of any rights of Administrative Agent to collect other proceeds of runs thereafter.

(e) Subordination of Obligor’s Liens.

(i) Each Obligor hereby subordinates and assigns in favor of Administrative Agent for the benefit of the Lenders any and all liens, statutory or otherwise and any rights of offset contractual or otherwise it has or may have in the future against such Obligors’ interests in the Mortgaged Properties or in the Oil and Gas Properties and revenues attributable to its interest therein, including the Contracts and Records (defined below).

(ii) Any officer or employee of Administrative Agent is expressly granted the right at its option upon not less than one (1) Business Day’s notice, to visit and inspect (a) each Obligors’ offices, including all books and records, farmout agreements, area of mutual interest agreements, development agreements, geologic and geophysical survey agreements, operating agreements, contracts and other agreements that relate to any of the Mortgaged Properties or in the Oil and Gas Properties, seismic, geological and geophysical, drilling and production data and records, all accounting records, joint interest billing records, division order records, land files, and contracts and records referring to the production, sale, purchase, exchange or processing of Hydrocarbons whether such data, information or agreements are in written form or electronic format (the “Contracts and Records”), and to examine, take copies and extracts therefrom, and (b) any of the Mortgaged Properties.

(iii) Following the occurrence and during the continuance of an Event of Default, each Obligor acknowledges that the Administrative Agent is expressly granted the right to exercise any and all liens, statutory or otherwise, rights of offset or recoupment it has and to receive the monies, income, proceeds, or benefits attributable to the sale of Oil and Gas produced from or attributable to the Mortgaged Properties, to hold the same as security for the Indebtedness and to apply it on the principal and interest or other amounts owing on any of the Indebtedness, whether or not then due, in such order or manner as Administrative Agent may elect.

(iv) In the event of a foreclosure, deed in lieu, or other transfer of record or beneficial ownership or operations of the Mortgaged Properties, each Obligor, as bailee, agrees to cooperate and assist Administrative Agent and its officers, agents and counsel in the peaceful transfer and delivery of such Contracts and Records to such party or parties as Administrative Agent may in writing direct.

(v) Following the occurrence and during the continuance of a Default or Event of Default and within thirty (30) days after receipt of notice from Administrative Agent, Obligors will relinquish their respective rights to operate the Properties of Obligors to the Administrative Agent or its designee.

(f) Pledge of Partnerships. Borrower shall and shall cause each of its Wholly Owned Subsidiaries that are not Unrestricted Entities to pledge all of its interest in any Partnership and to provide such information about such Partnership as Lenders may reasonably request.

(g) Subordination of Intercompany Debt. Any Intercompany Notes or advances of any Obligor howsoever evidenced by journal entries or otherwise now or hereafter owed to or held by any other Obligor are hereby subordinated to the Indebtedness of such other Obligor to the Lenders, and any document or instrument evidencing such loans or advances shall contain a legend giving notice of such subordination. Any Intercompany Notes or advances of any other Obligor due to such Obligor, if the Administrative Agent so requests, shall be collected, enforced and received by such Obligor as trustee for the Lenders and be paid over to the Administrative Agent for the account of the Lenders on account of the Indebtedness but without affecting in any manner the liability of such Obligor under the other provisions of this Agreement or any other Loan Document. Any Lien, claim, right or other encumbrance on any property of any Obligor in favor of any other Obligor is hereby subordinated in all respects to the Liens granted to the Administrative Agent for the benefit of the Lenders.

Section 8.10 ERISA Information and Compliance. The Obligors will promptly furnish and will cause the Subsidiaries and any ERISA Affiliate to promptly furnish to the Administrative Agent with sufficient copies to the Lenders (i) promptly after the filing thereof with the United States Secretary of Labor, the Internal Revenue Service or the PBGC, copies of each annual and other report with respect to each Plan or any trust created thereunder, (ii) immediately upon becoming aware of the occurrence of any ERISA Event or of any “prohibited transaction,” as described in section 406 of ERISA or in section 4975 of the Code, in connection with any Plan or any trust created thereunder, a written notice signed by a Responsible Officer specifying the nature thereof, what action the Obligors, the Subsidiary or the ERISA Affiliate is taking or proposes to take with respect thereto, and, when known, any action taken or proposed by the Internal Revenue Service, the Department of Labor or the PBGC with respect thereto, and (iii) immediately upon receipt thereof, copies of any notice of the PBGCs intention to terminate or to have a trustee appointed to administer any Plan. With respect to each Plan (other than a Multiemployer Plan), the Obligors will, and will cause each Subsidiary and ERISA Affiliate to, (i) satisfy in full and in a timely manner, without incurring any late payment or underpayment charge or penalty and without giving rise to any lien, all of the contribution and funding requirements of section 412 of the Code (determined without regard to subsections (d), (e), (f) and (k) thereof) and of section 302 of ERISA (determined without regard to sections 303, 304 and 306 of ERISA), and (ii) pay, or cause to be paid, to the PBGC in a timely manner, without incurring any late payment or underpayment charge or penalty, all premiums required pursuant to sections 4006 and 4007 of ERISA.

(a) Notwithstanding that, under Article III of the Mortgages, the Obligors thereto have unconditionally assigned to Administrative Agent for the ratable benefit of the Lenders all of the proceeds of runs accruing to the Mortgaged Properties covered thereby:

(i) Until such time as Administrative Agent shall notify such Obligors to the contrary, Obligors shall be entitled to receive from the purchasers or disbursers of production all such proceeds of runs, subject however to the liens created under the Mortgages, which liens are hereby affirmed and ratified.

(ii) In no case shall any failure, whether purposed or inadvertent, by Administrative Agent to collect directly any such proceeds of runs constitute in any way a waiver, remission or release of any of its rights under the Mortgages, nor shall any release of any other proceeds of runs or of any rights of Administrative Agent to collect other proceeds of runs thereafter.

(iii) Obligors will upon the instruction of Administrative Agent join with Administrative Agent in notifying, in writing and accompanied (if necessary) by certified copies of the Mortgages, the purchasers or disbursers of production, produced from the Mortgaged Properties, of the existence of the Mortgages, and instructing that all proceeds of runs be paid directly to Administrative Agent for the ratable benefit of the Lenders.

(i) Until such time as Administrative Agent shall notify such Obligors to the contrary, Obligors shall be entitled to receive and retain all such Distributions, subject however to the security interests created under the Pledges, which liens are hereby affirmed and ratified. Automatically upon an Event of Default under Section 10.01(f) or (g) and upon the occurrence and during the continuance of any other Event of Default, Administrative Agent may exercise all rights and remedies granted under the Pledges, including the right to obtain possession of all Distributions then held by Obligors or to receive directly from the Subsidiaries and Partnerships making such payments all future Distributions attributable to the Collateral.

(ii) In no case shall any failure, whether purposed or inadvertent, by Administrative Agent to collect directly any such Distributions constitute in any way a waiver, remission or release of any of its rights under the Pledges, nor shall any release of any other Distributions or of any rights of Administrative Agent to collect other Distributions thereafter.

(iii) Obligors will upon the instruction of Administrative Agent join with Administrative Agent in notifying in writing to the entities responsible for making such Distributions of the existence of the Pledges, and instructing that all Distributions be paid directly to Administrative Agent for the ratable benefit of the Lenders.

ARTICLE XI

The Administrative Agent

Section 11.01 Appointment, Powers and Immunities. Each Lender hereby irrevocably appoints and authorizes the Administrative Agent to act as its agent hereunder and under the Security Instruments with such powers as are specifically delegated to the Administrative Agent by the terms of this Agreement and the Security Instruments, together with such other powers as are reasonably incidental thereto. The Administrative Agent (which term as used in this sentence and in Section 11.05 and the first sentence of Section 11.06 shall include reference to its Affiliates and its and its Affiliates’ officers, directors, employees, attorneys, accountants, experts and agents): (i) shall have no duties or responsibilities except those expressly set forth in the Loan Documents, and shall not by reason of the Loan Documents be a trustee or fiduciary for any Lender; (ii) makes no representation or warranty to any Lender and shall not be responsible to the Lenders for any recitals, statements, representations or warranties contained in this Agreement, or in any certificate or other document referred to or provided for in, or received by any of them under, this Agreement, or for the value, validity, effectiveness, genuineness, execution, effectiveness, legality, enforceability or sufficiency of this Agreement, any Note

or any other document referred to or provided for herein or for any failure by any of the Obligors or any other Person (other than the Administrative Agent) to perform any of its obligations hereunder or thereunder or for the existence, value, perfection or priority of any collateral security or the financial or other condition of the Borrower, its Subsidiaries or any other obligor or guarantor; (iii) except pursuant to Section 11.07 shall not be required to initiate or conduct any litigation of collection proceedings hereunder; and (iv) shall not be responsible for any action taken or omitted to be taken by it hereunder or under any other document or instrument referred to or provided for herein or in connection herewith including its own ordinary negligence, except for its own gross negligence or willful misconduct. The Administrative Agent may employ agents, accountants, attorneys and experts and shall not be responsible for the negligence or misconduct of any such agents, accountants, attorneys or experts selected by it in good faith or any action taken or omitted to be taken in good faith by it in accordance with the advice of such agents, accountants, attorneys or experts. The Administrative Agent may deem and treat the payee of any Note as the holder thereof for all purposes hereof unless and until a written notice of the assignment or transfer thereof permitted hereunder shall have been filed with the Administrative Agent. The Administrative Agent is authorized to release any collateral that is permitted to be sold or released pursuant to the terms of the Loan Documents.

Section 11.02 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon any certification, notice or other communication (including any thereof by telephone, telex, telecopier, telegram or cable) believed by it to be genuine and correct and to have been signed or sent by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by the Administrative Agent.

Section 11.03 Defaults. The Administrative Agent shall not be deemed to have knowledge of the occurrence of a Default (other than the non-payment of principal of or interest on Loans or of fees or failure to reimburse for Letter of Credit drawings) unless the Administrative Agent has received notice from a Lender or the Borrower specifying such Default and stating that such notice is a “Notice of Default”. In the event that the Administrative Agent receives such a notice of the occurrence of a Default, the Administrative Agent shall give prompt notice thereof to the Lenders. In the event of a payment Default, the Administrative Agent shall give each Lender prompt notice of each such payment Default.

Section 11.04 Rights as a Lender. With respect to its Commitments and the Loans made by it and its participation in the issuance of Letters of Credit, Wachovia Bank, National Association (and any successor acting as Administrative Agent) in its capacity as a Lender hereunder shall have the same rights and powers hereunder as any other Lender and may exercise the same as though it were not acting as the Administrative Agent, and the term “Lender” or “Lenders” shall, unless the context otherwise indicates, include the Administrative Agent in its individual capacity. Wachovia Bank, National Association (and any successor acting as Administrative Agent) and its Affiliates may (without having to account therefor to any Lender) accept deposits from, lend money to and generally engage in any kind of banking, trust or other business with the Obligors (and any of their Affiliates) as if it were not acting as the Administrative Agent, and Wachovia Bank, National Association and its Affiliates may accept fees and other consideration from the Obligors for services in connection with this Agreement or otherwise without having to account for the same to the Lenders.

Section 11.05 Indemnification. The Lenders agree to indemnify the Administrative Agent and the Issuing Bank ratably in accordance with their Percentage Shares for the indemnity matters as described in Section 12.03 to the extent not indemnified or reimbursed by the Obligors under Section 12.03, but without limiting the obligations of the Obligors under said Section 12.03 and for any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Administrative Agent or the Issuing Bank in any way relating to or arising out of: (1) this Agreement, the Security Instruments or any other documents contemplated by or referred to herein or the

transactions contemplated hereby, but excluding, unless a Default has occurred and is continuing, normal administrative costs and expenses incident to the performance of its agency duties hereunder or (ii) the enforcement of any of the terms of this Agreement, any Security Instrument or of any such other documents; WHETHER OR NOT ANY OF THE FOREGOING SPECIFIED IN THIS SECTION 11.05 ARISES FROM THE SOLE OR CONCURRENT NEGLIGENCE OF THE ADMINISTRATIVE AGENT OR THE ISSUING BANK, provided that no Lender shall be liable for any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the Administrative Agent.

Section 11.06 Non-Reliance on Administrative Agent and other Lenders. Each Lender acknowledges and agrees that it has, independently and without reliance on the Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own credit analysis of the Obligors and its decision to enter into this Agreement, and 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 deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under this Agreement. The Administrative Agent shall not be required to keep itself informed as to the performance or observance by the Obligors of this Agreement, the Notes, the Security Instruments or any other document referred to or provided for herein or to inspect the properties or books of the Obligors. 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 not have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of the Obligors (or any of their Affiliates) which may come into the possession of the Administrative Agent or any of its Affiliates. In this regard, each Lender acknowledges that Xxxxxx and Xxxxx, LLP 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 Lender will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein.

Section 11.07 Action by Administrative Agent. Except for action or other matters expressly required of the Administrative Agent hereunder, the Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall (i) receive written instructions from the Majority Lenders (or all of the Lenders as expressly required by Section 12.04) 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 of the Majority Lenders (or all of the Lenders as expressly required by Section 12.04) 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, the Administrative Agent shall take such action with respect to such Default as shall be directed by the Majority Lenders (or all of the Lenders as required by Section 12.04) in the written instructions (with indemnities) described in this Section 11.07, 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 and the Security Instruments or applicable law.

Section 11.08 Resignation or Removal of Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided below, the Administrative Agent may resign at any time by giving notice thereof to the Lenders and the Borrower, and the Administrative Agent may be removed at any time with or without cause by the Majority Lenders. Upon any such resignation or removal, the Majority Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Majority Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent’s giving of

notice of resignation or the Majority Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent. Upon the acceptance of such appointment 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 retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent, the provisions of this Article XI and Section 12.03 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Administrative Agent.

ARTICLE XII

Section 12.14 Interest. It is the intention of the parties hereto to conform strictly to Applicable Usury Laws regarding the use, forbearance or detention of the indebtedness evidenced by this Agreement, the Notes and the other Loan Documents, whether such laws are now or hereafter in effect, including the laws of the United States of America or any other jurisdiction whose laws are applicable, and including any subsequent revisions to or judicial interpretations of those laws, in each case to the extent they are applicable to this Agreement, the Notes and the other Loan Documents (the “Applicable Usury Laws”). Accordingly, if any acceleration of the maturity of the Notes or any payment by Borrower or any other Person produces a rate in excess of the Highest Lawful Rate or otherwise results in Borrower or such other Person being deemed to have paid any interest in excess of the Maximum Amount, as hereinafter defined, or if any Lender shall for any reason receive any unearned interest in violation of any Applicable Usury Laws, or if any transaction contemplated hereby would otherwise be usurious under any Applicable Usury Laws, then, in that event, regardless of any provision contained in this Agreement or any other Loan Document or other agreement or instrument executed or delivered in connection herewith, the provisions of this Section 12.14 shall govern and control, and neither Borrower nor any other Person shall be obligated to pay, or apply in any manner to, any amount that would be excessive interest. No Lender shall ever be deemed to have contracted for or be entitled to receive, collect, charge, reserve or apply as interest on any Loan (whether termed interest therein or deemed to be interest by judicial determination or operation of law), any amount in excess of the Highest Lawful Rate, and, in the event that such Lender ever receives, collects, or applies as interest any such excess, such amount which would be excessive interest shall be applied as a partial prepayment of principal and treated hereunder as such, and, if the principal amount of the applicable Loans are paid in full, any remaining excess shall forthwith be paid to Borrower. In determining whether or not the interest contracted for, received, collected, charged, reserved, paid or payable, including under any specific contingency, exceeds the Highest Lawful Rate, Borrower and each Lender shall, to the maximum extent permitted under applicable law, (a) characterize any non-principal payment (other than payments which are expressly designated as interest payments hereunder) as an expense or fee rather than as interest, (b) exclude voluntary pre-payments and the effect thereof, and (c) amortize and spread the total amount of interest throughout the entire stated term of the Loans so that the interest rate is uniform throughout such term; provided that if the Loans are paid in full prior to the end of the full contemplated term hereof, and if the interest received for the actual period of existence thereof exceeds the Highest Lawful Rate, if any, then the Lenders shall refund to Borrower the amount of such excess, or credit the amount of such excess against the aggregate unpaid principal balance of all Loans made by Lender. As used herein, the term “Maximum Amount” means the maximum nonusurious amount of interest which may be lawfully contracted for, reserved, charged, collected or received by Lender in connection with the indebtedness evidenced by this Agreement, the Notes and other Loan Documents under all Applicable Usury Laws. Texas Finance Code, Chapter 346, which regulates certain revolving loan accounts and revolving tri-party accounts, shall not apply to any revolving loan accounts created under, or apply in any manner to, the Note, this Agreement or the other Loan Documents.

Section 12.15 Confidentiality. Subject to provisions under Section 12.16 below, in the event that the Borrower provides to the Administrative Agent or the Lenders written confidential information belonging to the Borrower, if the Borrower shall denominate such information in writing as “confidential,” the Administrative Agent and the Lenders shall thereafter maintain such information in confidence in accordance with the standards of care and diligence that each utilizes in maintaining its own

confidential information. This obligation of confidence shall not apply to such portions of the information which (i) are in the public domain, (ii) hereafter become part of the public domain without the Administrative Agent or the Lenders breaching their obligation of confidence to the Borrower, (iii) are previously known by the Administrative Agent or the Lenders from some source other than the Borrower, (iv) are hereafter developed by the Administrative Agent or the Lenders without using the Borrower’s information, (v) are hereafter obtained by or available to the Administrative Agent or the Lenders from a third party who owes no obligation of confidence to the Borrower with respect to such information or through any other means other than through disclosure by the Borrower, (vi) are disclosed with the Borrower’s consent, (vii) must be disclosed either pursuant to any Governmental Requirement or to Persons regulating the activities of the Administrative Agent or the Lenders provided, Administrative Agent and Lenders shall endeavor to provide notice to the Borrower as soon as practicable in the event Borrower desires to enjoin the disclosure of such information, however, failure of Administrative Agent or Lenders to provide such prior notice to Borrower shall not give rise to any claim or cause of action by Borrower or any Obligor against Administrative Agent or such Lenders, or (viii) as may be required by law or regulation or order of any Governmental Authority in any judicial, arbitration or governmental proceeding. Further, the Administrative Agent or a Lender may disclose any such information to any other Lender, any independent petroleum engineers or consultants, any independent certified public accountants, any legal counsel employed by such Person in connection with this Agreement or any Security Instrument, including without limitation, the enforcement or exercise of all rights and remedies thereunder, or any assignee or participant (including prospective assignees and participants) in the Loans; provided, however, that the Administrative Agent or the Lenders shall receive a confidentiality agreement from the Person to whom such information is disclosed such that said Person shall have the same obligation to maintain the confidentiality of such information as is imposed upon the Administrative Agent or the Lenders hereunder. Notwithstanding anything to the contrary provided herein, this obligation of confidence shall cease three (3) years from the date the information was furnished, unless the Borrower requests in writing at least thirty (30) days prior to the expiration of such three year period, to maintain the confidentiality of such information for an additional three year period. The Borrower waives any and all other rights it may have to confidentiality as against the Administrative Agent and the Lenders arising by contract, agreement, statute or law except as expressly stated in this Section 12.15.

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