The Administrative Agent, with the approval or deemed approval of the Lenders as set forth in Section 2.04(b), but subject to the terms of Section 2.04(b), shall, in good faith, redetermine the Borrowing Base based upon such information and such other information (including, without limitation, information described in the Reserve Report, the status of title with respect to the Oil and Gas Properties and the existence of any other Indebtedness) as the Administrative Agent deems appropriate in its discretion and consistent with customary industry practices and its normal oil and gas lending criteria as it exists at the particular time. Such redetermination shall be accomplished not later than and effective on or about the first day of each May and November of each calendar year, assuming that the Borrower shall have furnished the Reserve Report and other reports, data and supplemental information in a timely and complete manner as required by Section 5.11. In assessing whether to approve or reject a proposed Borrowing Base, each Lender will assess, in good faith, the Reserve Report and the other information as they deem appropriate in its discretion and consistent with customary industry practices and its respective oil and gas lending criteria and procedures as they exist at the particular time.

(d) Consensus and Failure of Consensus. Except as hereinafter provided, the decision of the Lenders or the Required Lenders, as applicable, with respect to any Borrowing Base determination shall control; provided, however, that if the Lenders or the Required Lenders, as applicable, have not approved or are not deemed to have approved the Borrowing Base as of the end of the 15-day period specified in Section 2.04(b), the Borrowing Base shall be redetermined at the highest amount approved by each Lender (if such redetermined Borrowing Base constitutes an increase in the Borrowing Base in effect immediately prior thereto) or the Required Lenders (if such redetermined Borrowing Base constitutes a reaffirmation or decrease in the Borrowing Base in effect immediately prior thereto), as applicable, and such amount shall then become the Borrowing Base until the next scheduled redetermination pursuant to Section 2.04(b) or the next date on which an interim redetermination occurs under Section 2.04(e) or the next adjustment under either Section 5.17, 6.01(j) or 6.13. Notwithstanding the foregoing, however, any increase in the Borrowing Base shall require approval or deemed approval of all the Lenders as set forth in Section 2.04(a).

(e) Interim Redeterminations. The Borrower may, at its option, one time during any 12-month period initiate an interim redetermination of the Borrowing Base. In addition, the Borrower may, at its option, in connection with any acquisition (or any series of acquisitions occurring since the most recent redetermination of the Borrowing Base) by the Parent, the

Borrower or a Restricted Subsidiary of Oil and Gas Properties having a purchase price, either individually or in the aggregate, of $50,000,000 or more, initiate an interim redetermination of the Borrowing Base. The Administrative Agent (at the direction of the Required Lenders, in their option) may one time during any 12-month period initiate an interim redetermination of the Borrowing Base. The Borrowing Base also may be redetermined in accordance with this Agreement upon the occurrence of any of the events described in any of Sections 5.12, 5.17, 6.01(j) or 6.13.

SECTION 2.05. Increase in Aggregate Commitment Amount.

(a) Upon prior notice to the Administrative Agent, the Borrower may from time to time, (i) request that the Lenders increase the Aggregate Commitment Amount pro rata among the Lenders up to an amount not exceeding the Maximum Facility Amount or (ii) invite additional financial institutions acceptable to the Administrative Agent and the Issuing Bank to become Lenders party to the Agreement so as to increase the Aggregate Commitment Amount to an amount not exceeding the Maximum Facility Amount. At the time of sending such notice to the Lenders or any invitee, the Borrower (in consultation with the Administrative Agent) shall specify the time period within which each Lender or invitee, as applicable, is requested to respond (which shall in no event be less than 10 Business Days from the date of delivery of such notice to the Lenders). If the Borrower has requested that the Lenders increase their respective Commitment Amounts pro rata hereunder, each Lender shall notify the Administrative Agent within such time period whether or not it agrees to increase its respective Commitment Amount and, if so, whether by an amount equal to, greater than, or less than its Applicable Percentage of such requested increase and any Lender not responding within such time period shall be deemed to have declined to increase its respective Commitment Amount. Anything herein contained to the contrary notwithstanding, no Lender shall have any obligation whatsoever to increase its respective Commitment Amount hereunder. The consent of the Lenders shall not be required in order for any financial institution acceptable to the Administrative Agent and the Issuing Bank to become a party to this Agreement pursuant to this Section 2.05.

(b) If the Aggregate Commitment Amount is increased in accordance with this Section 2.05, the Administrative Agent and the Borrower shall determine the effective date of such increase (the “Increase Effective Date”). The Administrative Agent and the Borrower shall promptly notify the Lenders of the final allocation of such increase and the Increase Effective Date. Each existing Lender that increases its Commitment Amount and each additional Lender, if any, and the Borrower shall execute and deliver to the Administrative Agent (which the Administrative Agent shall also execute to acknowledge its acceptance thereof) an agreement substantially in the form of Exhibit B (an “Additional Lender Agreement”). Upon receipt by the Administrative Agent of Additional Lender Agreements from existing Lenders or additional Lenders (together with an Administrative Questionnaire, in the case of any additional Lender), if any, in an amount sufficient to effectuate the increase requested by the Borrower: (1) the Aggregate Commitment Amount shall be increased, (2) the Administrative Agent shall amend and distribute to the Borrower and the Lenders a revised Schedule 2.01 of the Commitment Amounts of each Lender adding or amending, as applicable, the Commitment Amount of any Lender executing the Additional Lender Agreement and the revised Applicable Percentages of the Lenders (which shall be deemed incorporated into this Agreement), (3) any additional Lender shall be deemed to be a party in all respects to this Agreement and the other Loan Documents to

which the Lenders are party as of the Increase Effective Date and (4) upon the Increase Effective Date, any increasing or additional Lender party to the Additional Lender Agreement shall purchase from each of the (other) Lenders party to the Agreement immediately prior to the Increase Effective Date a pro rata portion of the outstanding Loans (and participation interests in Letters of Credit) of each such (other) Lender such that each Lender (including any additional Lender, if any) shall hold its respective Applicable Percentage of the outstanding Loans (and participation interests in Letters of Credit) as reflected on the revised Schedule 2.01 required by this Section 2.05, provided that the Borrower shall pay any amounts due under Section 2.16 to the extent that any such purchase gives rise to the costs indemnified thereby.

(c) As a condition precedent to such increase, the Borrower shall deliver to the Administrative Agent a certificate dated as of the Increase Effective Date (in sufficient copies for each Lender) signed by a Authorized Officer of the Borrower (i) certifying and attaching the resolutions adopted by the Borrower approving or consenting to such increase, (ii) including a certificate of the type described in Section 5.01(c) demonstrating pro forma compliance with Section 6.09 after giving effect to such increase and (iii) certifying that, before and after giving effect to such increase, the representations and warranties contained in Article III are true and correct on and as of the Increase Effective Date and no Default or Event of Default exists.

(d) This Section shall supersede any provision in Section 9.02 to the contrary.

SECTION 2.06. Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of Letters of Credit as the applicant thereof, for its own account or the account of any other Credit Party, in a form reasonably acceptable to the Administrative Agent and the Issuing Bank, at any time and from time to time during the Availability Period. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the Issuing Bank) to the Issuing Bank and the Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension, but in any event no less than three Business Days) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) of this Section), the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by the Issuing Bank, the Borrower also shall submit a letter of credit application on the Issuing Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter

of Credit the Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension, (i) the LC Exposure shall not exceed $20,000,000 and (ii) the aggregate Credit Exposure shall not exceed the lesser of (x) the Aggregate Commitment Amount and (y) the Borrowing Base then in effect, in each case, as such amounts may be adjusted from time to time in accordance with this Agreement.

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the earlier of (i) the close of business on the date that is five Business Days prior to the Maturity Date and (ii) one year after its issuance, provided, however, that any Letter of Credit with a one-year term may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the fifth Business Day prior to the Maturity Date) unless the Issuing Bank provides prior notice of non-renewal to the beneficiary thereof.

(d) Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided in paragraph (e) of this Section, or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on (i) the Business Day that the Borrower receives such notice, if such notice is received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that the Borrower shall, subject to the conditions to borrowing set forth herein, automatically be deemed to have requested in accordance with Section 2.03 that such payment be financed with an ABR Borrowing in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Borrowing. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.07 with respect to Loans made by such Lender (and Section 2.07 shall apply, mutatis mutandis, to the payment obligations of

the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this paragraph, the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse the Issuing Bank for any LC Disbursement (other than the funding of ABR Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

(f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in paragraph (e) of this Section shall be absolute, unconditional and irrevocable and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not strictly comply with the terms of such Letter of Credit or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Except as set forth herein, neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any damages (other than special, indirect or consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination (AND THE PARTIES HERETO ACKNOWLEDGE AND AGREE THAT IT IS THE INTENTION OF THE PARTIES HERETO THAT THE ISSUING BANK BE EXCUSED FOR ITS OWN NEGLIGENCE (OTHER THAN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT), REGARDLESS OF WHETHER SUCH NEGLIGENCE IS SOLE OR CONTRIBUTORY, ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL). In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented that appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Lenders with respect to any such LC Disbursement.

(h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans; provided that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.13(c) shall apply. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of this Section to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among the Borrower, the Administrative Agent and the successor Issuing Bank, with the consent of the replaced Issuing Bank, such consent not to be unreasonably withheld or delayed. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.12(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

(j) Cash Collateralization. If any Event of Default shall occur and be continuing or if required pursuant to Section 2.11, on the Business Day that the Borrower receives notice from the Administrative Agent or the Majority Lenders demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to the LC Exposure as of such date, plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in

clause (h) or (i) of Section 7.01. The Borrower hereby grants to the Administrative Agent, for the benefit of the Issuing Bank and the Lenders, an exclusive first priority and continuing perfected security interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all deposits or wire transfers made thereto, any and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise payable in respect of, or in exchange for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Majority Lenders), be applied to satisfy other obligations of the Borrower under this Agreement. If at any time the amount of cash collateral held by the Administrative Agent pursuant hereto shall exceed the LC Exposure as of such date, Administrative Agent shall return such excess to the Borrower within two Business Days thereafter. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived.

SECTION 2.07. Funding of Borrowings.

(a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 1:00 p.m., New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Administrative Agent designated by the Borrower in the applicable Borrowing Request; provided that ABR Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.06(e) shall be remitted by the Administrative Agent to the Issuing Bank.

(b) Unless the Administrative Agent shall have received written notice from a Lender prior to the proposed date of any Eurodollar Borrowing or prior to 1:00 p.m., New York City time, on the date any proposed ABR Borrowing, as applicable, that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in

fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith within two Business Days after demand therefor such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

SECTION 2.08. Interest Elections.

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

(b) To make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by the Borrower.

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

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

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

(iii) with respect to any Borrowing, whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

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

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

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

(e) If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Majority Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

SECTION 2.09. Termination and Reduction of Commitments.

(a) Unless previously terminated, each Lender’s Commitment shall terminate on the Maturity Date.

(b) The Borrower may at any time terminate, or from time to time reduce, the Commitments; provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of $5,000,000 and not less than $5,000,000 and (ii) the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.11, the Credit Exposure would exceed the total Commitments, as so reduced.

(c) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Commitments shall be permanent, subject to the Borrower’s right to request an increase in the Aggregate Commitment Amount pursuant to Section 2.05. Each reduction of the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments.

SECTION 2.10. Repayment of Loans; Evidence of Debt.

(a) The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan on the Maturity Date.

(b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(d) The entries made in the accounts maintained pursuant to paragraphs (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein absent manifest error; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

(e) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent; provided that any promissory note issued to evidence any Lender’s Loans shall be in a stated amount equal to such Lender’s Commitment Amount. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 9.04) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

SECTION 2.11. Prepayment of Loans.

(a) Mandatory Prepayments. At any time that a Borrowing Base Deficiency shall occur, the Borrower shall:

(i) If such Borrowing Base Deficiency results from a redetermination of the Borrowing Base pursuant to Sections 2.04(b), 2.04(e) or 5.12, at the Borrower’s election, take either or both of the following actions to eliminate the Borrowing Base Deficiency: (A) prepay the Loans in an aggregate principal amount equal to such Borrowing Base Deficiency, together with interest on the principal amount paid accrued to the date of such prepayment and any funding indemnification amounts required by Section 2.16, and, if a Borrowing Base Deficiency remains after prepaying all of the Loans as a result

of LC Exposure, 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 in a special collateral account as provided in Section 2.06(j), or (B) provide additional Collateral acceptable to the Administrative Agent with a fair market value greater than or equal to the amount of such Borrowing Base Deficiency. The Borrower shall be obligated to make such prepayment, deposit of cash collateral or provide additional Collateral within 60 days following its receipt of written notice from the Administrative Agent of the existence of the Borrowing Base Deficiency.

(ii) If such Borrowing Base Deficiency results from a reduction of the Borrowing Base in accordance with Sections 5.17, 6.01(j) or 6.13, use the Net Cash Proceeds of the transaction giving rise to the reduction of the Borrowing Base pursuant to any such Section, promptly, but in any event within two Business Days of receipt of such Net Cash Proceeds, to prepay the Loans in an aggregate principal amount equal to such Borrowing Base Deficiency, together with interest on the principal amount paid accrued to the date of such prepayment and any funding indemnification amounts required by Section 2.16, and, if a Borrowing Base Deficiency remains after prepaying all of the Loans as a result of LC Exposure, 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 in a special collateral account as provided in Section 2.06(j); provided that if, after application of such Net Cash Proceeds in accordance with the foregoing, any Borrowing Base Deficiency shall remain, then the Borrower shall eliminate such remaining Borrowing Base Deficiency in accordance with the foregoing clause (i).

(iii) Amounts applied to the prepayment of Loans pursuant to this Section shall be first applied ratably to ABR Loans then outstanding and, upon payment in full of all outstanding ABR Loans, second, to Eurodollar Loans then outstanding, and if more than one Eurodollar Loan is then outstanding, to each such Eurodollar Loan beginning with the Eurodollar Loan with the fewest number of days remaining in the Interest Period applicable thereto until paid in full, and then to the Eurodollar Loan with the next fewest number of days remaining in the Interest Period applicable thereto until paid in full, and continuing in a similar fashion until the Borrowing Base Deficiency has been eliminated or, in the case of any prepayment pursuant to the foregoing clause (ii), until such Net Cash Proceeds have been exhausted.

(b) Optional Prepayment of Loans. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, without premium or penalty, but subject to the requirements of Sections 2.09(b) and 2.16. The Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any optional prepayment (i) in the case of a Eurodollar Borrowings, not later than 12:00 noon, New York City time, three Business Days before the date of prepayment or (ii) in the case of prepayment of any ABR Borrowings, not later than 12:00 noon New York City time, on the date of such prepayment. Such notice shall be irrevocable and shall specify the prepayment date and the principal amount of the Borrowings or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.09, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.09. Promptly following receipt of any such notice of

prepayment, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowings shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.13 and any amount payable under Section 2.16.

SECTION 2.12. Fees.

(a) Subject to the provisions of Section 2.20, the Borrower agrees to pay to the Administrative Agent, for the account of each Lender (excluding any Defaulting Lenders), an unused commitment fee (the “Unused Commitment Fee”) equal to the Applicable Rate set forth under the heading Unused Commitment Fee Rate multiplied by the daily average of each such Lender’s Unused Commitment. Such Unused Commitment Fee shall be calculated on the basis of a year consisting of 360 days and shall be payable in arrears on the last day of each March, June, September and December and on the Maturity Date for any period then ending for which the Unused Commitment Fee shall not have been previously paid. In the event the Commitments terminate on any date other than the last day of March, June, September or December, the Borrower agrees to pay to the Administrative Agent, for the account of each Lender (excluding any Defaulting Lenders), on the date of such termination, each such Lender’s Unused Commitment Fee due for the period from the last day of the immediately preceding March, June, September or December, as the case may be, to the date such termination occurs.

(b) Subject to the provisions of Section 2.20, the Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender (excluding any Defaulting Lenders) a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Rate used to determine the interest rate applicable to Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank a fronting fee as set forth in the Fee Letter, as well as the Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable on the third Business Day following such last day, commencing on the first such date to occur after the Effective Date; provided that all such fees shall be payable on the date on which the Commitments terminate and any such fees accruing after the date on which the Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be payable within 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

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

(d) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for distribution, in the case of Unused Commitment Fees and participation fees, to the Lenders. Fees paid shall not be refundable under any circumstances, except in the case of any overpayment due to erroneous calculation or invoicing thereof.

SECTION 2.13. Interest.

(a) The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Rate.

(b) Eurodollar Loans shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate.

(c) Notwithstanding the foregoing, (i) if a Default or an Event of Default has occurred and is continuing, the Majority Lenders may, at their option, by notice to the Borrower declare that no Borrowing may be made as, converted into or continued as a Eurodollar Borrowing, (ii) during the continuance of an Event of Default the Majority Lenders may, at their option, by notice to the Borrower, declare that (A) each Eurodollar Borrowing shall bear interest for the remainder of the applicable Interest Period plus 2% per annum, (B) each ABR Borrowing shall bear interest at a rate per annum equal to the Alternate Base Rate in effect from time to time plus 2% per annum and (C) the fees described in Section 2.12(b) shall be increased by 2% per annum, provided that, during the continuance of an Event of Default under clauses (h) or (i) of Section 7.01, the interest rates forth in clauses (A) and (B) above and the increase in the Letter of Credit fee set forth in clause (C) above shall be applicable to all Borrowings without any election or action on the part of the Administrative Agent or any Lender (as applicable, the “Default Rate”).

(d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Commitments; provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Loan prior to the end of the Availability Period unless such prepayment is made to reduce a Borrowing Base Deficiency), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(e) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on Well Fargo Bank’s “prime rate” shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

SECTION 2.14. Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

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

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

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

SECTION 2.15. Increased Costs.

(a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement (including any compulsory loan requirement, insurance charge or other assessment) against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or the Issuing Bank; or

(ii) impose on any Lender or the Issuing Bank or the London interbank market any other condition, cost or expense affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender or the Issuing Bank of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or the Issuing Bank hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered.

(b) If any Lender or the Issuing Bank determines that any Change in Law regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the

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

(c) A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 Business Days after receipt thereof.

(d) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided, further, that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

SECTION 2.16. Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.11(b) and is revoked in accordance therewith) or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.05 or Section 2.19, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest that would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

SECTION 2.17. Taxes.

(a) General. Each payment by any Credit Party under any Loan Document shall be made without withholding for any Taxes, unless such withholding is required by law. If any Withholding Agent determines, in its sole discretion exercised in good faith, that it is so required to withhold Taxes, then such Withholding Agent may so withhold and shall timely pay the full amount of withheld Taxes to the relevant Governmental Authority in accordance with applicable law. If such Taxes are Indemnified Taxes, then the amount payable by any Credit Party shall be increased as necessary so that net of such withholding (including withholding applicable to additional amounts payable under this Section) the applicable Recipient receives the amount it would have received had no such withholding been made.

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

(c) Evidence of Payment. As soon as practicable after any payment of Indemnified Taxes by any Credit Party to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(d) Indemnification by the Borrower and the Parent. The Borrower and the Parent shall jointly and severally indemnify each Recipient for any Indemnified Taxes that are paid or payable by such Recipient in connection with any Loan Document (including amounts paid or payable under this Section 2.17(d)) and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. The indemnity under this Section 2.17(d) shall be paid within 10 days after the Recipient delivers to the Borrower a certificate stating the amount of any Indemnified Taxes so paid or payable by such Recipient or Beneficial Owner and describing the basis for the indemnification claim. Such certificate shall be conclusive of the amount so paid or payable absent manifest error. Such Recipient shall deliver a copy of such certificate to the Administrative Agent.

(e) Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent for any Taxes (but, in the case of any Indemnified Taxes, only to the extent that any Loan Party has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower and the Parent to do so) attributable to such Lender that are paid or payable by the Administrative Agent in connection with any Loan Document and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. The indemnity under this Section 2.17(e) shall be paid within 10 days after the Administrative Agent or the applicable Credit Party (as applicable) delivers to the applicable Lender a certificate stating the amount of Taxes so paid or payable by the Administrative Agent or the Borrower (as applicable). Such certificate shall be conclusive of the amount so paid or payable absent manifest error.

(f) Status of Lenders.

(i) Any Lender that is entitled to an exemption from, or reduction of, any applicable withholding Tax with respect to any payments under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without, or at a reduced rate of, withholding. In addition, any Lender, if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to any withholding (including backup withholding) or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences and except as otherwise required by applicable law, the completion, execution and submission of such documentation (other than such documentation set forth in Section 2.17(f)(ii)(A) through (E) below) shall not be required if in the Lender’s judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. Upon the reasonable request of such Borrower or the Administrative Agent, any Lender shall update any form or certification previously delivered pursuant to this Section 2.17(f). If any form or certification previously delivered pursuant to this Section expires or becomes obsolete or inaccurate in any respect with respect to a Lender, such Lender shall promptly (and in any event within 10 days after such expiration, obsolescence or inaccuracy) notify such Borrower and the Administrative Agent in writing of such expiration, obsolescence or inaccuracy and update the form or certification if it is legally eligible to do so.

(ii) Without limiting the generality of the foregoing, if the Borrower is a U.S. Person, any Lender with respect to such Borrower shall, if it is legally eligible to do so, deliver to such Borrower and the Administrative Agent (in such number of copies reasonably requested by such Borrower and the Administrative Agent) on or prior to the date on which such Lender becomes a party hereto, duly completed and executed copies of whichever of the following is applicable:

(A) in the case of a Lender that is a U.S. Person, IRS Form W-9 certifying that such Lender is exempt from U.S. Federal backup withholding tax;

(B) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (1) with respect to payments of interest under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the “interest” article of such tax treaty and (2) with respect to any other applicable payments under this Agreement, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(C) in the case of a Foreign Lender for whom payments under this Agreement constitute income that is effectively connected with such Lender’s conduct of a trade or business in the United States, IRS Form W-8ECI;

(D) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code both (1) IRS Form W-8BEN and (2) a certificate substantially in the form of Exhibit E (a “U.S. Tax Certificate”) to the effect that such Lender is not (a) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (b) a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code (c) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code and (d) conducting a trade or business in the United States with which the relevant interest payments are effectively connected;

(E) in the case of a Foreign Lender that is not the Beneficial Owner of payments made under this Agreement (including a partnership or a participating Lender) (1) an IRS Form W-8IMY on behalf of itself and (2) the relevant forms prescribed in clauses (A), (B), (C), (D) and (F) of this paragraph (f)(ii) that would be required of each such Beneficial Owner or partner of such partnership if such Beneficial Owner or partner were a Lender; provided, however, that if the Lender is a partnership and one or more of its partners are claiming the exemption for portfolio interest under Section 881(c) of the Code, such Lender may provide a U.S. Tax Certificate on behalf of such partners; or

(F) any other form prescribed by law as a basis for claiming exemption from, or a reduction of, U.S. Federal withholding Tax together with such supplementary documentation necessary to enable the Borrower or the Administrative Agent to determine the amount of Tax (if any) required by law to be withheld.

(iii) If a payment made to a Lender under any Loan Document would be subject to U.S. Federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Withholding Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Withholding Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Withholding Agent as may be necessary for the Withholding Agent to comply with its obligations under FATCA, to determine that such Lender has or has not complied with such Lender’s obligations under FATCA and, as necessary, to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 2.17(f)(iii), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(g) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified or Other Taxes paid by the Borrower pursuant to this Section 2.17 (including additional amounts paid pursuant to this Section 2.17), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made, or such Other Taxes paid, under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including any Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid such indemnified party pursuant to the previous sentence (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything herein to the contrary in this Section 2.17(g), in no event will any indemnified party be required to pay any amount to any indemnifying party pursuant to this Section 2.17(g) to the extent that such payment would place such indemnified party in a less favorable position (on a net after-Tax basis) than such indemnified party would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This Section 2.17(g) shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes which it deems confidential) to the indemnifying party or any other Person.

(h) Survival. Each party’s obligations under this Section 2.17 shall survive any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all other obligations under any Loan Document.

(i) Issuing Bank. For purposes of Section 2.17(e) and (f), the term “Lender” includes any Issuing Bank.

SECTION 2.18. Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.15, 2.16 or 2.17, or otherwise) prior to 12:00 noon, Dallas, Texas time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices as set forth in Section 9.02(a), except payments to be made directly to the Issuing Bank as expressly provided herein and except that payments pursuant to Sections 2.15, 2.16, 2.17 and 9.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.06(d) or (e), 2.07(b), 2.18(d) or 9.03(c), then the Administrative Agent may, in its

discretion and notwithstanding any contrary provision hereof, (i) apply any amounts thereafter received by the Administrative Agent for the account of such Lender and for the benefit of the Administrative Agent or the Issuing Bank to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid and/or (ii) hold any such amounts in a segregated account over which the Administrative Agent shall have exclusive control as cash collateral for, and application to, any future funding obligations of such Lender under such Sections; in the case of each of (i) and (ii) above, in any order as determined by the Administrative Agent in its discretion.

SECTION 2.19. Mitigation Obligations; Replacement of Lenders.

(a) If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.15 or 2.17, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, or if any Lender becomes a Defaulting Lender, or if any Lender fails to execute an amendment or waiver with respect to the Loan Documents that is executed by the Required Lenders, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent (and if a Commitment is being assigned, the Issuing Bank), which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

SECTION 2.20. Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(a) fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Lender pursuant to Section 2.12(a);

(b) the Commitment and Credit Exposure of such Defaulting Lender shall not be included in determining whether all Lenders, the Majority Lenders or the Required Lenders have taken or may take any action hereunder (including any consent to any amendment, waiver or other modification pursuant to Section 9.02); provided that (i) such Defaulting Lender’s Commitment may not be increased or extended without its consent and (ii) the principal amount of, or interest or fees payable on, Loans or LC Disbursements may not be reduced or excused or the scheduled date of payment may not be postponed as to such Defaulting Lender without such Defaulting Lender’s consent;

(i) all or any part of such LC Exposure shall be reallocated among the non-Defaulting Lenders in accordance with their respective Applicable Percentages but only to the extent (x) the sum of all non-Defaulting Lenders’ Credit Exposures plus such Defaulting Lender’s LC Exposure does not exceed the total of all non-Defaulting Lenders’ Commitments and (y) the conditions set forth in Section 4.02 are satisfied at such time;

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall within one Business Day following notice by the Administrative Agent cash collateralize such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.06(j) for so long as such LC Exposure is outstanding;

(iii) if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to Section 2.20(c), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.12(b) with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized;

(iv) if the LC Exposure of the non-Defaulting Lenders is reallocated pursuant to Section 2.20(c), then the fees payable to the Lenders pursuant to Section 2.12(a) and Section 2.12(b) shall be adjusted in accordance with such non-Defaulting Lenders’ Applicable Percentages; or

None of the Parent, the Borrower or any Restricted Subsidiary is in default nor has any event or circumstance occurred that, but for the expiration of any applicable grace period or the giving of notice, or both, would constitute a default under any Unsecured Notes Documents, any Permitted Second Lien Loan Document (if any) or any other material agreement or instrument to which the Borrower or any Restricted Subsidiary is a party or by which the Borrower or any Restricted Subsidiary is bound, which default could reasonably be expected to have a Material Adverse Effect. No Default hereunder has occurred and is continuing.

There is no fact peculiar to the Parent, the Borrower or any Restricted Subsidiary that has a Material Adverse Effect or in the future is reasonably likely to have (so far as the Parent or the Borrower can now foresee) a Material Adverse Effect and that 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 Parent, the Borrower or any Restricted Subsidiary prior to, or on, the Effective Date in connection with the transactions contemplated hereby. There are no statements or conclusions in any Reserve Report which are based upon or include misleading information or fail to take into account material information regarding the matters reported therein, it being understood that each Reserve Report is necessarily based upon professional opinions, estimates and projections and that neither the Parent nor the Borrower warrants that such opinions, estimates and projections will ultimately prove to have been accurate.

The June 30 Reserve Report of each year shall be prepared by or under the supervision of the Manager of Engineering of the Parent, who shall have the Approved Petroleum Engineer certify such Reserve Report to be true and accurate and to have been substantially prepared in accordance with the procedures used in the immediately preceding December 31 Reserve Report.

(b) In the event of an unscheduled redetermination of the Borrowing Base, the Parent or the Borrower shall furnish to the Administrative Agent and the Lenders a Reserve Report prepared by or under the supervision of the Manager of Engineering of the Parent who shall have the Approved Petroleum Engineer certify such Reserve Report to be true and accurate and to have been substantially prepared in accordance with the procedures used in the immediately preceding Reserve Report. For any unscheduled redetermination requested by the Required Lenders or the Parent or the Borrower pursuant to Section 2.04(e), the Parent or the Borrower shall provide such Reserve Report with an “as of” date as required by the Administrative Agent as soon as possible, but in any event no later than 30 days following the receipt of such request.

(c) With the delivery of each Reserve Report, the Parent or the Borrower shall provide to the Administrative Agent and the Lenders, a certificate from an Authorized Officer certifying that, to his knowledge (after reasonable inquiry) and in all material respects: (i) the information contained in the Reserve Report and any other information delivered in connection therewith is true and correct, (ii) the Parent, the Borrower or the Restricted Subsidiaries owns good and defensible title to the Oil and Gas Properties evaluated in such Reserve Report and such Properties are free of all Liens except for Liens permitted by Section 6.02, (c) except as set forth on an exhibit to the certificate, on a net basis there are no gas imbalances, take or pay or other prepayments with respect to the Oil and Gas Properties evaluated in such Reserve Report which would require the Parent, the Borrower or any Restricted Subsidiary to deliver

Hydrocarbons produced from such Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor, (d) none of such Oil and Gas Properties have been sold since the date of the last Borrowing Base determination except as set forth on an exhibit to the certificate, which certificate shall list the Oil and Gas Properties sold and in such detail as reasonably required by the Majority Lenders, and (e) attached thereto is a schedule of the Oil and Gas Properties evaluated by such Reserve Report that are subject to Mortgages.

SECTION 5.12. Title Information.

(a) On or before the delivery to the Administrative Agent and the Lenders of each Reserve Report required by Section 5.11, the Parent or the Borrower will deliver title information in form and substance reasonably acceptable to the Administrative Agent covering enough of the Oil and Gas Properties evaluated by such Reserve Report so that the Administrative Agent shall have received together with title information previously delivered to the Administrative Agent, satisfactory title information on at least 80% of the total value of the proved Oil and Gas Properties evaluated by such Reserve Report.

(b) If the Parent and the Borrower have provided title information for additional Properties under Section 5.12(a), the Parent and the Borrower shall, within 60 days of notice from the Administrative Agent that title defects or exceptions exist with respect to such additional Properties, either (i) cure any such title defects or exceptions (including defects or exceptions as to priority) that are not permitted by Section 6.02 raised by such information, (ii) substitute acceptable proved Oil and Gas Properties with no title defects or exceptions (except for Liens permitted pursuant to Section 6.02) having an equivalent value or (iii) deliver title information in form and substance acceptable to the Administrative Agent so that the Administrative Agent shall have received, together with title information previously delivered to the Administrative Agent, satisfactory title information on at least 80% of the total value of the proved Oil and Gas Properties evaluated by such Reserve Report.

(c) If the Parent and the Borrower are unable to cure any title defect requested by the Administrative Agent or the Lenders to be cured within the 60-day period or if neither the Parent nor the Borrower complies with the requirements to provide acceptable title information covering 80% of the total value of the proved Oil and Gas Properties evaluated in the most recent Reserve Report, such default shall not be a Default or an Event of Default, but instead the Administrative Agent and the Lenders shall have the right to exercise the following remedy in their sole discretion from time to time, and any failure to so exercise this remedy at any time shall not be a waiver as to future exercise of the remedy by the Administrative Agent or the Lenders. To the extent that the Administrative Agent or the Lenders are not satisfied with title to any such Oil and Gas Property after the 60-day period has elapsed and the value attributed to all such unacceptable Oil and Gas Property during any period between two successive regularly scheduled Redetermination Dates, when aggregated with (A) the net reduction (determined in accordance with Section 5.17) in the value attributable to the Credit Party’s Swap Agreements during such period and (B) the Fair Market Value assigned to any Oil and Gas Properties (or Restricted Subsidiaries owning Oil and Gas Properties) sold, transferred, assigned or conveyed pursuant to Section 6.13 during such period by the Required Lenders in good faith in determining the Borrowing Base then in effect, exceeds five percent (5%) of the Borrowing Base then in effect, the Administrative Agent and the Required Lenders shall have the right to reduce the Borrowing Base in accordance with Section 2.04.

SECTION 5.13. Additional Collateral; Additional Guarantors.

(a) In connection with each redetermination of the Borrowing Base, the Borrower shall review the Reserve Report and the list of current Oil and Gas Properties subject to Mortgages to ascertain whether such Oil and Gas Properties represent at least 80% of the total value of the proved Oil and Gas Properties evaluated in the most recent Reserve Report and included in the Borrowing Base after giving effect to exploration and production activities, acquisitions, dispositions and production. In the event that the Oil and Gas Properties subject to Mortgages do not represent at least 80% of such total value, then the Parent or the Borrower shall, and shall cause the Restricted Subsidiaries to, grant to the Administrative Agent as security for the Secured Obligations a first-priority Lien interest (subject only to Liens permitted pursuant to Section 6.02) on additional Oil and Gas Properties not already subject to a Lien of the Collateral Documents such that after giving effect thereto, the Oil and Gas Properties subject to Mortgages will represent at least 80% of such total value. All such Liens will be created and perfected by and in accordance with the provisions of mortgages, deeds of trust, security agreements and financing statements or other Collateral Documents, all in form and substance reasonably satisfactory to the Administrative Agent and in sufficient executed (and acknowledged where necessary or appropriate) counterparts for recording purposes. In order to comply with the foregoing, if any Restricted Subsidiary places a Lien on its Oil and Gas Properties and such Restricted Subsidiary is not a Guarantor, then it shall become a Guarantor and comply with Section 5.13(b). Notwithstanding anything to the contrary in this Agreement or any other Loan Document, the Administrative Agent, the Lenders and the Credit Parties acknowledge and agree that no “building” or “mobile home” (each as defined in Regulation H promulgated under the Flood Insurance Laws) shall secure the Secured Obligations or constitute Mortgaged Property or Collateral (and to the extent that any Lien created under any Security Document encumbers any “building” or “mobile home” (each as defined in Regulation H promulgated under the Flood Insurance Laws) to secure the Secured Obligations, the Administrative Agent is authorized to deliver a release with respect such “building” or “mobile home”).

(b) The Parent and the Borrower shall promptly cause each Restricted Subsidiary that either (x) is or becomes a Material Domestic Subsidiary or (y) has guaranteed the Unsecured Notes, any Permitted Second Lien Debt (if any) or other Material Indebtedness, in each case, to guarantee the Secured Obligations pursuant to a Guaranty.

(A) for the 12-month period from the date such hedging trade or transaction is created, (x) 85% of the reasonably anticipated production of natural gas, (y) 85% of the reasonably anticipated production of oil and (z) 85% of the reasonably anticipated production of natural gas liquids and condensate, in each case, from the Credit Parties’ proved Hydrocarbon Interests as set forth on the most recent Reserve Report,

(B) for the 12-month period commencing with the first anniversary of the date such hedging trade or transaction is created, (x) 75% of the reasonably anticipated production of natural gas, (y) 75% of the reasonably anticipated production of oil and (z) 75% of the reasonably anticipated production of natural gas liquids and condensate, in each case, from the Credit Parties’ proved Hydrocarbon Interests as set forth on the most recent Reserve Report,

Dates have a Fair Market Value (individually or in the aggregate) that, when aggregated with (i) the value attributed to all title defects with respect to Borrowing Base Properties identified during such period and (ii) the net reduction (determined in accordance with Section 5.17) in the value attributable to the Credit Party’s Swap Agreements during such period, exceeds five percent (5%) of the Borrowing Base then in effect, the Borrowing Base shall be reduced in an amount equal to the value, if any, assigned such Property by the Required Lenders in good faith in determining the Borrowing Base then in effect; and provided, further, that if any such sale or other disposition is of a Restricted Subsidiary owning Oil and Gas Properties, such sale or other disposition shall include all the Equity Interests of such Restricted Subsidiary.

Thereafter, the Lenders shall have five days to approve or object to such proposed amount; and any failure to object shall be deemed to be an approval. In the event there is no approval or deemed approval, the Administrative Agent shall poll the Lenders to ascertain the smallest reduction to the Borrowing Base then acceptable to a number of Lenders sufficient to constitute the Required Lenders for purposes of this Section 6.13 and such amount shall then be the allocated value of the Property subject to such sale or disposition.

SECTION 8.03. Duties and Obligations of Administrative Agent. The Administrative Agent shall not have any duties or obligations except those expressly set forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing as directed by the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02), and (c) except as expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Parent, the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02) or in the absence of its own gross negligence or willful misconduct (IT BEING THE INTENTION OF THE PARTIES HERETO THAT THE ADMINISTRATIVE AGENT BE INDEMNIFIED IN THE CASE OF ITS OWN NEGLIGENCE (OTHER THAN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT), REGARDLESS OF WHETHER SUCH NEGLIGENCE IS SOLE OR CONTRIBUTORY, ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL).

SECTION 8.04. Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

SECTION 8.05. Subagents. The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

SECTION 8.06. Resignation or Removal of Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrower. Upon any such resignation, the Majority Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall 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. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

SECTION 8.07. No Reliance. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such

documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder. In this regard, each Lender acknowledges that Mayer Brown LLP is acting in this transaction as special counsel to the Administrative Agent only. Each other party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with this Agreement and the other Loan Documents and the matters contemplated herein and therein.

SECTION 9.02. Waivers; Amendments.

(a) No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Majority Lenders or by the Borrower and the Administrative Agent with the consent of the Majority Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, increase the Borrowing Base or amend the specified approval standards set forth in Section 2.04 without the written consent of each Lender or maintain or decrease the Borrowing Base without the written consent of the Required Lenders, (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest

Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder, except that the Commitment of such Lender may not be increased or extended without the consent of such Lender.

SECTION 9.03. Expenses; Indemnity; Damage Waiver. (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iii) all reasonable out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, the Issuing Bank or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, or in connection with the Loans made or Letters of Credit issued hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit.

(b) THE PARENT AND THE BORROWER SHALL INDEMNIFY THE ADMINISTRATIVE AGENT, THE ISSUING BANK AND EACH LENDER, AND EACH RELATED PARTY OF ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON

BEING CALLED AN “INDEMNITEE”), AGAINST, AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES AND RELATED EXPENSES, INCLUDING THE REASONABLE FEES, CHARGES AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH OR AS A RESULT OF (I) THE EXECUTION OR DELIVERY OF THIS AGREEMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY, THE PERFORMANCE BY THE PARTIES HERETO OF THEIR RESPECTIVE OBLIGATIONS HEREUNDER OR THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREBY, (II) ANY LOAN OR LETTER OF CREDIT OR THE USE OF THE PROCEEDS THEREFROM (INCLUDING ANY REFUSAL BY THE ISSUING BANK TO HONOR A DEMAND FOR PAYMENT UNDER A LETTER OF CREDIT IF THE DOCUMENTS PRESENTED IN CONNECTION WITH SUCH DEMAND DO NOT STRICTLY COMPLY WITH THE TERMS OF SUCH LETTER OF CREDIT), (III) ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF HAZARDOUS MATERIALS ON OR FROM ANY PROPERTY OWNED OR OPERATED BY THE PARENT, THE BORROWER OR ANY OF THE RESTRICTED SUBSIDIARIES, OR ANY ENVIRONMENTAL LIABILITY RELATED IN ANY WAY TO THE PARENT, THE BORROWER OR ANY OF THE RESTRICTED SUBSIDIARIES, OR (IV) ANY ACTUAL OR PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY AND REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO; PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES OR RELATED EXPENSES ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE (IT BEING ACKNOWLEDGED AND AGREED THAT IT IS THE INTENTION OF THE PARTIES HERETO THAT THE INDEMNITEES BE INDEMNIFIED IN THE CASE OF THEIR OWN NEGLIGENCE (OTHER THAN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT), REGARDLESS OF WHETHER SUCH NEGLIGENCE IS SOLE OR CONTRIBUTORY, ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL).

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

(d) To the extent permitted by applicable law, neither the Parent nor the Borrower shall assert, and each hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with or as a result of this Agreement or any agreement or instrument contemplated hereby, any Loan or Letter of Credit or the use of the proceeds thereof.

(e) All amounts due under this Section shall be payable promptly after written demand therefor.

SECTION 9.04. Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) neither the Parent nor the Borrower may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Issuing Bank and each Lender (and any attempted assignment or transfer by the Parent or the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of:

(A) the Borrower, provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, any other assignee;

(B) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment of any Commitment to an assignee that is a Lender with a Commitment immediately prior to giving effect to such assignment; and

(C) the Issuing Bank, provided that no consent of the Issuing Bank shall be required for an assignment of any Commitment to an assignee that is a Lender with a Commitment immediately prior to giving effect to such assignment;

provided, however, that no Lender may assign all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) to the Parent or any Affiliate of the Parent or any natural person (or any company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural person or relative(s) thereof), in each case, without the consent of all of the Lenders.

100

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

(A) except in the case of an assignment to a Lender or an Affiliate of a Lender, the amount of the Commitment Amount of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, provided that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing;

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

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

(D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire in which the assignee designates one or more individuals to whom all syndicate-level information (which may contain material non-public information about the Credit Parties and their related parties or their respective securities) will be made available and who may receive such information in accordance with the assignee’s compliance procedures and applicable laws, including Federal and state securities laws.

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.15, 2.16 and 2.17 (with respect to amounts accruing during the period such Lender was a party hereto and for which such Lender was entitled to reimbursement or indemnity) and Section 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section. If the consent of the Borrower to an assignment is required hereunder (including a consent to an assignment that does not meet the minimum assignment thresholds specified in this Section), the Borrower shall be deemed to have given its consent ten days after the date notice thereof has been delivered by the assigning Lender (through the Administrative Agent) unless such consent is expressly refused by the Borrower prior to such tenth day.

(iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption

101

delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant to Section 2.06(d) or (e), 2.07(b), 2.18(d) or 9.03(c), the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c) Any Lender may, without the consent of the Borrower, the Administrative Agent or the Issuing Bank, sell participations to one or more banks or other entities (a “Participant”), other than the Borrower or any Affiliate of the Borrower or any natural person (or any company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural person or relative(s) thereof), in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects such Participant. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.15, 2.16 and 2.17 (subject to the requirements and limitations therein, including the requirements under Section 2.17(f) (it being understood that the documentation required under Section 2.17(f) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Sections 2.18 and 2.19 as if it were an

102

assignee under paragraph (b) of this Section; and (B) shall not be entitled to receive any greater payment under Sections 2.15 or 2.17, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided that such Participant agrees to be subject to Section 2.18(c) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under this Agreement (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Loans, Letters of Credit or its other obligations under any this Agreement or any other Loan Document) except to the extent that such disclosure is necessary to establish that such Commitment, Loan, Letter of Credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary.

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

SECTION 9.05. Survival. All covenants, agreements, representations and warranties made by the Parent or the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Sections 2.15, 2.16, 2.17 and 9.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof.

SECTION 9.06. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single

103

This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or other electronic transmission shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 9.07. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 9.08. Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Parent or the Borrower against any of and all the obligations of the Parent or the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender may have.

(a) Each of the Administrative Agent, the Issuing Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (i) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that (A) the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential and (B) in any event, any subsequent disclosure by its or its Affiliates’ directors, officers or employees shall be deemed to be, and treated as if it were, a disclosure by, as applicable, the Administrative Agent, the Issuing Bank or such Lender), (ii) to the extent requested by any regulatory or self-regulatory authority, (iii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (iv) to any other party to this Agreement, (v) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (vi) subject to an agreement containing provisions substantially the same as those of this Section, to (x) any assignee of or Participant in, or any prospective assignee of or Participant

105

in, any of its rights or obligations under this Agreement or (y) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Parent or the Borrower and its obligations, (vii) with the consent of the Borrower or (viii) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis from a source other than the Parent or the Borrower. For the purposes of this Section, “Information” means all information received from the Parent or the Borrower relating to the Parent, the Borrower or their respective businesses, other than any such information that is available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Parent or the Borrower. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

(b) EACH LENDER ACKNOWLEDGES THAT INFORMATION AS DEFINED IN SECTION 9.12(a) FURNISHED TO IT PURSUANT TO THIS AGREEMENT MAY INCLUDE MATERIAL NON-PUBLIC INFORMATION CONCERNING THE PARENT, THE BORROWER AND ITS RELATED PARTIES OR THEIR RESPECTIVE SECURITIES AND CONFIRMS THAT IT HAS DEVELOPED COMPLIANCE PROCEDURES REGARDING THE USE OF MATERIAL NON-PUBLIC INFORMATION AND THAT IT WILL HANDLE SUCH MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH THOSE PROCEDURES AND APPLICABLE LAW, INCLUDING FEDERAL AND STATE SECURITIES LAWS.

(c) ALL INFORMATION, INCLUDING REQUESTS FOR WAIVERS AND AMENDMENTS, FURNISHED BY THE PARENT, THE BORROWER OR THE ADMINISTRATIVE AGENT PURSUANT TO, OR IN THE COURSE OF ADMINISTERING, THIS AGREEMENT WILL BE SYNDICATE-LEVEL INFORMATION, WHICH MAY CONTAIN MATERIAL NON-PUBLIC INFORMATION ABOUT THE PARENT, THE BORROWER, THE CREDIT PARTIES AND THEIR RELATED PARTIES OR THEIR RESPECTIVE SECURITIES. ACCORDINGLY, EACH LENDER REPRESENTS TO THE BORROWER AND THE ADMINISTRATIVE AGENT THAT IT HAS IDENTIFIED IN ITS ADMINISTRATIVE QUESTIONNAIRE A CREDIT CONTACT WHO MAY RECEIVE INFORMATION THAT MAY CONTAIN MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH ITS COMPLIANCE PROCEDURES AND APPLICABLE LAW.

SECTION 9.13. Interest Rate Limitation. The Parent, the Borrower, the Administrative Agent and the Lenders intend to strictly comply with all applicable laws, including applicable usury laws. Accordingly, the provisions of this Section 9.13 shall govern and control over every other provision of this Agreement or any other Loan Document that conflicts or is inconsistent with this Section 9.13, even if such provision declares that it controls. As used in this Section 9.13, the term “interest” includes the aggregate of all charges, fees, benefits or other compensation which constitute interest under applicable law, provided that, to the maximum extent permitted by applicable law, (a) any non-principal payment shall be characterized as an expense or as compensation for something other than the use, forbearance or detention of money

106

and not as interest, and (b) all interest at any time contracted for, reserved, charged or received shall be amortized, prorated, allocated and spread, in equal parts during the full term of the Obligations. In no event shall the Parent, the Borrower or any other Person be obligated to pay, or any Lender have any right or privilege to reserve, receive or retain, (i) any interest in excess of the maximum amount of nonusurious interest permitted under the applicable laws (if any) of the United States or of any other applicable state or (ii) total interest in excess of the amount which such Lender could lawfully have contracted for, reserved, received, retained or charged had the interest been calculated for the full term of the Obligations at the Highest Lawful Rate. On each day, if any, that the interest rate (the “Stated Rate”) called for under this Agreement or any other Loan Document exceeds the Highest Lawful Rate, the rate at which interest shall accrue shall automatically be fixed by operation of this sentence at the Highest Lawful Rate for that day, and shall remain fixed at the Highest Lawful Rate for each day thereafter until the total amount of interest accrued equals the total amount of interest which would have accrued if there were no such ceiling rate as is imposed by this sentence. Thereafter, interest shall accrue at the Stated Rate unless and until the Stated Rate again exceeds the Highest Lawful Rate when the provisions of the immediately preceding sentence shall again automatically operate to limit the interest accrual rate. The daily interest rates to be used in calculating interest at the Highest Lawful Rate shall be determined by dividing the applicable Highest Lawful Rate per annum by the number of days in the calendar year for which such calculation is being made. None of the terms and provisions contained in this Agreement or in any other Loan Document that directly or indirectly relate to interest shall ever be construed without reference to this Section 9.13, or be construed to create a contract to pay for the use, forbearance or detention of money at an interest rate in excess of the Highest Lawful Rate. If the term of any Obligation is shortened by reason of acceleration of maturity as a result of any Event of Default or by any other cause, or by reason of any required or permitted prepayment, and if for that (or any other) reason any Lender at any time, including but not limited to, the stated maturity, is owed or receives (and/or has received) interest in excess of interest calculated at the Highest Lawful Rate, then and in any such event all of any such excess interest shall be canceled automatically as of the date of such acceleration, prepayment or other event which produces the excess, and, if such excess interest has been paid to such Lender, it shall be credited pro tanto against the then-outstanding principal balance of the Borrower’s obligations to such Lender, effective as of the date or dates when the event occurs which causes it to be excess interest, until such excess is exhausted or all of such principal has been fully paid and satisfied, whichever occurs first, and any remaining balance of such excess shall be promptly refunded to its payor.

SECTION 9.14. Collateral Matters; Lender Party Swap Agreements and Lender Party Financial Service Products. The benefit of the Collateral Documents and of the provisions of this Agreement relating to the Collateral shall also extend to, secure and be available on a pro rata basis (as set forth in Section 7.03 of this Agreement) to each Lender or Affiliate of a Lender (or Existing Lender party to a Lender Party Swap Agreement or Lender Party Financial Service Product entered into while such Existing Lender was a “Lender” under the Existing Credit Facility or any predecessor credit agreement to the Existing Credit Facility) that is (i) a counterparty to a Lender Party Swap Agreement (including any Lender Party Swap Agreement in existence prior to the date hereof) or (ii) a provider under a Lender Party Financial Service Product (including any Lender Party Financial Service Product in existence prior to the date hereof), in each case, with respect to any obligations of the Parent, the Borrower or any Restricted Subsidiary arising under such Lender Party Swap Agreement or Lender Party

107

Financial Service Product, as applicable, but only with respect to any Lender Party Swap Agreement or Lender Party Financial Service Product, and the transactions thereunder, that were entered into while such Person or its Affiliate was a Lender (or an Existing Lender) or prior to such time until such obligations are paid in full or otherwise expire or are terminated (and notwithstanding that the outstanding Obligations have been repaid in full and the Commitments have terminated); provided that, with respect to any Lender Party Swap Agreement or Lender Party Financial Service Product that remains secured after the counterparty thereto or provider of Financial Service Product thereunder is no longer a Lender or an Affiliate of a Lender or the outstanding Obligations have been repaid in full and the Commitments have terminated, the provisions of Article VIII shall also continue to apply to such counterparty or provider in consideration of its benefits hereunder and each such counterparty or provider shall, if requested by the Administrative Agent, promptly execute and deliver to the Administrative Agent all such other documents, agreements and instruments reasonably requested by the Administrative Agent to evidence the continued applicability of the provisions of Article VIII. Notwithstanding the foregoing, no Lender or Affiliate of a Lender (or former Lender or Affiliate of a former Lender) shall have any voting or consent right under this Agreement or any Collateral Document as a result of the existence of obligations owed to it under a Lender Party Swap Agreement or Lender Party Financial Service Product that is secured by any Collateral Document.

SECTION 9.15. No Third Party Beneficiaries. This Agreement, the other Loan Documents, and the agreement of the Lenders to make Loans and the Issuing Bank to issue, amend, renew or extend Letters of Credit hereunder are solely for the benefit of the Parent and the Borrower, and no other Person (including, without limitation, any Subsidiary of the Borrower, any obligor, contractor, subcontractor, supplier or materialman) shall have any rights, claims, remedies or privileges hereunder or under any other Loan Document against the Administrative Agent, any other Agent, the Issuing Bank or any Lender for any reason whatsoever. There are no third party beneficiaries.

SECTION 9.16. USA PATRIOT Act. Each Lender that is subject to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”) hereby notifies the Parent, the Borrower and the Guarantors that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies the Parent, the Borrower and the Guarantors, which information includes the name and address of the Parent, the Borrower and the Guarantors and other information that will allow such Lender to identify the Parent, the Borrower and the Guarantors in accordance with the Patriot Act.

SECTION 9.17. NO ORAL AGREEMENTS. THE LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

THIS SUBORDINATION AGREEMENT (this “Agreement”) dated as of [ ], by and among [ ], a [ ] and [ ], a [ ] (“[ ]”, and together with [ ], collectively the “PVA Debtors”), and [ ], a [ ] (the “Subordinated Creditor”), and in favor of Wells Fargo Bank, National Association, as administrative agent (“Administrative Agent”), for the benefit of the Senior Creditors (as defined herein).

RECITALS

PVHC is a party to that certain Credit Agreement dated as of September 28, 2012, with PVC, as Parent, the lenders party thereto (the “Lenders”), the Administrative Agent and the other persons party thereto in the capacities therein specified (as amended, refinanced, modified or supplemented from time to time, the “Credit Agreement”).

2. The PVA Debtors, except for PVHC (the “Guarantors”), have delivered a certain Guaranty dated as of September 28, 2012, pursuant to which the Guarantors have guaranteed all of the “Obligations” (as defined in the Credit Agreement) under the Credit Agreement and the other Loan Documents.

3. The Subordinated Creditor has made or may make certain intercompany loans or advances to PVA Debtors.

4. To induce the Administrative Agent, the Issuing Bank and the Lenders to enter into the Credit Agreement and make the loans and other extensions of credit contemplated thereby, the Subordinated Creditor has agreed to execute and deliver this Agreement and subordinate the indebtedness of the PVA Debtors owed to the Subordinated Creditor to all of the “Obligations” (as defined in the Credit Agreement) owed to the Lenders under the Credit Agreement or the “Guaranteed Obligations” (as defined in the Guaranty) of the Guarantors, as the case may be, and the other Loan Documents related thereto.

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

ARTICLE I

DEFINITIONS

SECTION 1.01. Definitions. Unless otherwise defined herein, all capitalized terms referred to herein shall have the meaning given to them in the Credit Agreement.

“Senior Creditors” shall mean the Administrative Agent, the Lenders (including any Lender acting as an “Issuing Bank” under the Credit Agreement) and any Lender or Affiliate of a Lender party to Lender Party Swap Agreement or a Lender Party Financial Service Product, and any permitted assignees of any of the foregoing pursuant to the terms of the Credit Agreement.

Exhibit D-1

“Senior Indebtedness” shall mean any and all indebtedness, liabilities and obligations owed by any PVA Debtor to any Lender, Affiliate of a Lender, Issuing Bank or Administrative Agent under the Loan Documents, any Lender Party Swap Agreement or any Lender Party Financial Service Product. The Senior Indebtedness shall include amounts accruing subsequent to the filing of any bankruptcy, receivership, insolvency or similar petition.

“Subordinated Indebtedness” shall mean, for each PVA Debtor, the Indebtedness of such PVA Debtor to any Subordinated Creditor.

ARTICLE II

SUBORDINATION

SECTION 2.01. Agreement to Subordinate. Each Subordinated Creditor agrees that the Subordinated Indebtedness is subordinated in right of payment, to the extent and in the manner provided in this Article II, to the payment when due of all Senior Indebtedness.

SECTION 2.02. Liquidation, Dissolution, Bankruptcy. Upon any payment or distribution of the assets of any PVA Debtor to creditors upon a total or partial liquidation or a total or partial dissolution of such PVA Debtor (other than, to the extent permitted by the Credit Agreement or the other Loan Documents, a voluntary dissolution of such PVA Debtor or merger of such PVA Debtor into any wholly owned subsidiary of any PVA Debtor solely for the purpose of permitting such PVA Debtor or such wholly owned Subsidiary to assume all obligations in respect of the Subordinated Indebtedness as if it were the direct obligor with respect thereto and in which all the assets of such PVA Debtor are transferred to such PVA Debtor or such wholly owned Subsidiary and no material payment or distribution is made to creditors) or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to such PVA Debtor or its Property:

(i) the Senior Creditors shall be entitled to receive payment in full in cash of such Senior Indebtedness before the Subordinated Creditor shall be entitled to receive any payments in respect of the Subordinated Indebtedness; and

(ii) until such Senior Indebtedness is paid in full in cash, any distribution made by or on behalf of any PVA Debtor to which any Subordinated Creditor would be entitled but for this Article II shall be made to the Senior Creditors as their interests may appear, except that Subordinated Creditor may receive and retain shares of stock and any debt securities that are subordinated to all Senior Indebtedness to at least the same extent as the Subordinated Indebtedness.

SECTION 2.03. Default on Senior Indebtedness. No PVA Debtor may make any payments in respect of the Subordinated Indebtedness nor repurchase, redeem or otherwise retire any of the Subordinated Indebtedness (collectively, “pay the Subordinated Indebtedness”) if a “Default” or “Event of Default” has occurred and is continuing under the Credit Agreement or such payment would create a “Default” or “Event of Default” thereunder; provided, however, any PVA Debtor may pay the Subordinated Indebtedness without regard to the foregoing if such PVA Debtor receives written notice approving such payment from the Administrative Agent.

Exhibit D-2

SECTION 2.04. When Distribution Must Be Paid Over. If a distribution or payment is made in respect of the Subordinated Indebtedness to a Subordinated Creditor that because of this Article II should not have been made to it, such Subordinated Creditor shall hold it in trust for the Senior Creditors and promptly pay it over to the Administrative Agent for the benefit of the Lenders, the Administrative Agent and the Issuing Bank.

SECTION 2.05. Subrogation. After all Senior Indebtedness is paid in full and until the Subordinated Indebtedness is paid in full, each Subordinated Creditor shall be subrogated to the rights of the Senior Creditors to receive distributions applicable to such Senior Indebtedness.

SECTION 2.06. Agreement Not to Pursue Actions. Until the Administrative Agent notifies the Subordinated Creditor that all Senior Indebtedness shall have been paid in full, the Subordinated Creditor will not commence any action or proceeding against any PVA Debtor to recover all or any part of the Subordinated Indebtedness or join with any other creditor, unless the Administrative Agent shall also join, in bringing any proceedings against such Person under any bankruptcy, reorganization, readjustment of debt, arrangement of debt, receivership, liquidation or insolvency law or statute of the Federal or any state government.

SECTION 2.07. Subordination May Not Be Impaired by Subordinated Creditor. No right of any Senior Creditor to enforce the subordination of the Subordinated Indebtedness shall be impaired by any act or failure to act by such Subordinated Creditor or by its failure to comply with this Agreement. The Senior Creditors may extend, renew, increase, modify or amend the terms of such Senior Indebtedness and otherwise deal freely with Subordinated Creditor, all without affecting the liabilities and obligations of the parties to this Agreement or any other Subordinated Creditor.

SECTION 2.08. Subordinated Creditor Not Fiduciary for Senior Creditors. Subordinated Creditor shall not be deemed to owe any fiduciary duty to the Senior Creditors and shall not be liable to any such Senior Creditor if it shall mistakenly pay over or distribute to any other Person, money or assets to which any Senior Creditor shall be entitled by virtue of this Article II or otherwise, unless such payment or distribution was a result of the negligence or willful misconduct of Subordinated Creditor.

SECTION 2.09. Reliance by Senior Creditors on Subordination Provisions. Subordinated Creditor acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each Senior Creditor, whether such Senior Indebtedness was created or acquired before or after the incurrence of the Subordinated Indebtedness, to acquire and continue to hold, or to continue to hold, such Senior Indebtedness and such Senior Creditor shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Indebtedness. Subordinated Creditor acknowledges and agrees that this Agreement is for the benefit of the Senior Creditors and any permitted assignees of the Senior Indebtedness, and each such Senior Creditor and assignee is a third party beneficiary of this Agreement and, as such, shall be entitled to enforce the obligations of Subordinated Creditor hereunder.

SECTION 2.10. Liens Subordinated. Subordinated Creditor agrees that the Subordinated Indebtedness shall be at all times unsecured, provided that if any Lien arises by

Exhibit D-3

statute or other operation of law upon the property of any PVA Debtor securing payments of the Subordinated Indebtedness, such Lien shall be and remain inferior and subordinated to any Liens securing payments of the Senior Indebtedness regardless of whether such encumbrances in favor of Subordinated Creditor or the Senior Creditors presently exist or are hereafter created or attached. If, notwithstanding the foregoing, Subordinated Creditor shall obtain a Lien on property of a PVA Debtor that is not subject to a Lien in favor of the Senior Creditors, then Subordinated Creditor agrees not to exercise any rights under the instruments evidencing such Liens, and not to receive any payments or distributions in respect of such Liens, until the Senior Creditors have received payment of the Senior Indebtedness in full in cash. If under any applicable bankruptcy, insolvency or other similar law, Subordinated Creditor receives a secured claim in lieu of a set-off, then Subordinated Creditor agrees not to exercise any rights under such secured claim, and not to receive any payments or distributions in respect of such secured claim, until the Senior Creditors have received payment of the Senior Indebtedness in full in cash.
