ARTICLE II

THE CREDITS

Section 2.01 Commitments. Subject to the terms and conditions set forth herein, each Lender agrees to make Loans to the Borrower during the Availability Period in an aggregate principal amount that will not result in (a) such Lender’s Revolving Credit Exposure exceeding such Lender’s Loan Commitment or (b) the Total Revolving Credit Exposures exceeding the Total Commitments. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, repay and reborrow the Loans.

Section 2.02 Loans and Borrowings.

(a) Borrowings; Several Obligations. Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance with their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments are several and no Lender shall be responsible for any other Lender’s failure to make Loans as required.

(b) Types of Loans. Subject to Section 3.03, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may request in accordance herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement.

(c) Minimum Amounts; Limitation on Number of Borrowings. At the commencement of each Interest Period for any Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $500,000 and not less than $1,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $250,000 and not less than $1,000,000; provided that an ABR Borrowing may be in an aggregate amount that is equal to the entire unused balance of the total Commitments or that is required to finance the reimbursement of a Letter of Credit Disbursement as contemplated by Section 2.08(e). Borrowings of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of twelve (12) Eurodollar Borrowings outstanding. Multiple Borrowings may be outstanding at the same time; provided that there shall not at any time be more than a total of three (3) Borrowings outstanding. Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

(d) Notes. The Loans made by each Lender shall be evidenced by a single promissory note of the Borrower in substantially the form of Exhibit A, dated, in the case of (i)

any Lender party hereto as of the date of this Agreement, as of the date of this Agreement or (ii) any Lender that becomes a party hereto pursuant to an Assignment and Assumption, as of the effective date of the Assignment and Assumption, payable to the order of such Lender in a principal amount equal to its Maximum Credit Amount as in effect on such date, and otherwise duly completed. In the event that any Lender’s Maximum Credit Amount increases or decreases for any reason (whether pursuant to Section 2.06, Section 12.04(b) or otherwise), the Borrower shall deliver or cause to be delivered on the effective date of such increase or decrease, a new Note payable to the order of such Lender in a principal amount equal to its Maximum Credit Amount after giving effect to such increase or decrease, and otherwise duly completed and the affected Lender shall deliver the Note being replaced to the Borrower immediately. The date, amount, interest rate and Interest Period of each Loan made by each Lender, and all payments made on account of the principal thereof, shall be recorded by such Lender on its books for its Note, and, prior to any transfer, may be endorsed by such Lender on a schedule attached to such Note or any continuation thereof or on any separate record maintained by such Lender. Failure to make any such notation or to attach a schedule shall not affect any Lender’s or the Borrower’s rights or obligations in respect of such Loans or affect the validity of such transfer by any Lender of its Note.

Section 2.03 Requests for Borrowings. To request a Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone not later than Noon, New York time, three Business Days before the date of the proposed Borrowing, in the case of Eurodollar Borrowings, or on the same Business Day, in the case of ABR Borrowings. Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request in the form attached hereto as Exhibit 2.03. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02:

(i) the aggregate amount of the requested Borrowing;

(ii) the date of such Borrowing, which shall be a Business Day;

(iii) in the case of Eurodollar Borrowings, the initial Interest Period to be applicable to such Borrowing, which shall be a period contemplated by the definition of the term “Interest Period”;

(iv) the amount of the then effective Borrowing Base, the current Total Revolving Credit Exposures (without regard to the requested Borrowing) and the pro forma Total Revolving Credit Exposures (giving effect to the requested Borrowing); and

(v) the location and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.05.

In the case of Eurodollar Borrowings, if no Interest Period is specified with respect to any requested Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Each Borrowing Request shall constitute a representation that the amount of the requested Borrowing shall not cause the Total Revolving Credit Exposures to exceed the total Commitments (i.e., the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base).

Promptly following receipt of a Borrowing Request in accordance with this Section 2.03, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing.

Section 2.04 Interest Elections.

(a) Continuance. Each Borrowing initially shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to continue such Borrowing and may elect Interest Periods therefor, all as provided in this Section 2.04. 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) Interest Election Requests. To make an election pursuant to this Section 2.04, 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. 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 the form attached hereto as Exhibit 2.04(b) and signed by the Borrower.

(c) Information in Interest Election Requests. 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 Section 2.04(c)(iii) 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; and

(iii) the Interest Period to be applicable to such Borrowing 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 does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration.

(d) Notice to Lenders by the Administrative Agent. 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) Effect of Failure to Deliver Timely Interest Election Request and Events of Default and Borrowing Base Deficiencies on Interest Election. If the Borrower fails to deliver a timely Interest Election Request with respect to a 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 continued as a Loan having an Interest Period of one-month. Notwithstanding any contrary provision hereof, if an Event of Default or a Borrowing Base Deficiency has occurred and is continuing, then no outstanding Borrowing may be continued (and any Interest Election Request that requests the continuation of any Borrowing shall be ineffective).

Section 2.05 Funding of Borrowing.

(a) Funding by Lenders. 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 2:00 p.m., New York 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 and designated by the Borrower in the applicable Borrowing Request; provided that Loans made to finance the reimbursement of a Letter of Credit Disbursement as provided in Section 2.08(e) shall be remitted by the Administrative Agent to the Issuer that made such Letter of Credit Disbursement. Nothing herein shall be deemed to obligate any Lender to obtain the funds for its Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for its Loan in any particular place or manner.

(b) Presumption of Funding by the Lenders. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing 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 Section 2.05(a) 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 on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds 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 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 2.06 Termination and Reduction of Aggregate Maximum Credit Amounts.

(a) Scheduled Termination of Commitments. Unless previously terminated, the Commitments shall terminate on the Maturity Date. If at any time the Aggregate Maximum Credit Amounts or the Borrowing Base is terminated or reduced to zero, then the Commitments shall terminate on the effective date of such termination or reduction.

(b) Optional Termination and Reduction of Aggregate Credit Amounts.

(i) The Borrower may at any time terminate, or from time to time reduce, the Aggregate Maximum Credit Amounts; provided that (A) each reduction of the Aggregate Maximum Credit Amounts shall be in an amount that is an integral multiple of $500,000 and not less than $1,000,000 and (B) the Borrower shall not terminate or reduce the Aggregate Maximum Credit Amounts if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 3.03(c), the Total Revolving Credit Exposures would exceed the total Commitments.

(ii) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Aggregate Maximum Credit Amounts under Section 2.06(b)(i) 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 2.06(b)(ii) shall be irrevocable. Any termination or reduction of the Aggregate Maximum Credit Amounts shall be permanent and may not be reinstated. Each reduction of the Aggregate Maximum Credit Amounts shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage.

Section 2.07 Borrowing Base.

(a) For the period from and including the Closing Date to but excluding the date of the first determination of the Borrowing Base pursuant to the further provisions of this Section 2.07, the initial amount of the Borrowing Base has been set by the Administrative Agent and acknowledged by the Borrower and agreed to by the Lenders to be $100,000,000.

(b) Promptly after January 1 of each calendar year, commencing January 1, 2007, and in any event prior to March 31 of each calendar year (commencing March 31, 2007), the Borrower shall furnish to the Administrative Agent a Reserve Report in form and substance reasonably satisfactory to the Administrative Agent, prepared by an Approved Engineer, which Reserve Report shall be dated as of January 1 of such calendar year together with additional data concerning pricing, hedging, quantities and purchasers of production, and other information and engineering and geological data as the Administrative Agent may reasonably request. Within fifteen (15) days after receipt of all such Reserve Report and information, the Administrative Agent shall make an initial determination of the new Borrowing Base (the “Proposed Borrowing Base”), which for purposes of this Section 2.07(b) is the semi-annual determination described in Section 2.07(c), and upon such initial determination shall promptly notify the Lenders in writing of its initial determination of the Proposed Borrowing Base. Such initial determinations made by the Administrative Agent shall be so made by the Administrative Agent in the exercise of its sole discretion in accordance with the Administrative Agent’s customary practices and standards for oil and gas lending as they exist at the particular time. In no event shall the Proposed Borrowing Base exceed the aggregate Loan Commitments of the Lenders. The Required Lenders shall approve or reject the Administrative Agent’s initial determinations of the Proposed Borrowing Base by written notice to the Administrative Agent within fifteen (15) days of the Administrative Agent’s notification of its initial determinations; provided, however that failure by any Lender to

confirm in writing, the Administrative Agent’s determination of the Proposed Borrowing Base shall be and shall be deemed an approval of the Proposed Borrowing Base. If the Required Lenders fail to approve any such determination of the Proposed Borrowing Base made by the Administrative Agent hereunder in such fifteen (15) day period, then the Administrative Agent shall poll the Lenders to ascertain the highest Proposed Borrowing Base then acceptable to the Required Lenders for purposes of this Section 2.07(b) and, subject to the last sentence of this Section 2.07(b), such amounts shall become the new Borrowing Base, effective on the date specified in this Section 2.07. Until such approval or deemed approval, the Borrowing Base in effect before the Proposed Borrowing Base shall remain in effect. Upon agreement by the Administrative Agent and the Required Lenders of the new Borrowing Base, the Administrative Agent shall, by written notice to the Borrower and the Lenders, designate the new Borrowing Base available to the Borrower. Such designation shall be effective as of the Business Day specified in such written notice (or, if no effective date is specified in such written notice, the next Business Day following delivery of such written notice) and such new Borrowing Base shall remain in effect until the next determination or redetermination of the Borrowing Base in accordance with this Agreement. Anything herein contained to the contrary notwithstanding, any determination or redetermination of the Borrowing Base resulting in any increase of the Borrowing Base in effect immediately prior to such determination or redetermination shall require the approval of all the Lenders in their sole discretion in accordance with their respective customary practices and standards for oil and gas lending as they exist at the particular time.

(c) In addition, within ninety (90) days after each June 30, commencing June 30, 2007, the Borrower shall furnish to the Administrative Agent a Reserve Report in form and substance satisfactory to the Administrative Agent, prepared by the Borrower’s petroleum engineers or on behalf of Borrower by petroleum engineers under the Management Services Agreement, which report shall be dated as of July 1 of such calendar year together with additional data concerning pricing, hedging, quantities and purchasers of production, and other information and engineering and geological data as the Administrative Agent may reasonably request. Within fifteen (15) days after receipt of all such Reserve Report and information, the Administrative Agent shall make an initial determination of a Proposed Borrowing Base, and upon such initial determination shall promptly notify the Lenders in writing of initial determination of the Proposed Borrowing Base. Such initial determination shall be made in the same manner and be subject to the same approvals as prescribed above with respect to the annual review, and likewise the Administrative Agent shall communicate the results of such initial determinations to the Lenders. The Required Lenders shall approve such determinations of the Proposed Borrowing Base by written notice to the Administrative Agent within fifteen (15) days of the giving of notice of such determinations by the Administrative Agent to such Lenders; provided, however that failure by any Lender to confirm in writing the Administrative Agent’s determination of the Proposed Borrowing Base shall be, and shall be deemed, an approval of the Proposed Borrowing Base. If the Required Lenders fail to approve any such determination of the Proposed Borrowing Base made by the Administrative Agent hereunder in such fifteen (15) day period, then the Administrative Agent shall poll the Lenders to ascertain the highest Proposed Borrowing Base then acceptable to the Required Lenders for purposes of this Section 2.07(c) and, subject to the last sentence of this Section 2.07(c), such amounts shall become the new Borrowing Base, effective on the date specified in this Section 2.07. Upon agreement by the Administrative Agent and the Required Lenders of the amount of credit to be made available to the Borrower hereunder, the Administrative Agent shall, by written notice to the Borrower and

the Lenders, designate the new Borrowing Base available to the Borrower. Such designation shall be effective as of the Business Day specified in such written notice (or, if no effective date is specified in such written notice, the next Business Day following delivery of such written notice) and such new Borrowing Base shall remain in effect until the next determination or redetermination of the Borrowing Base in accordance with this Agreement. Anything herein contained to the contrary notwithstanding, any determination or redetermination of the Borrowing Base resulting in any increase of the Borrowing Base in effect immediately prior to such determination or redetermination shall require the approval of all the Lenders in their sole discretion in accordance with their respective customary practices and standards for oil and gas lending as they exist at the particular time.

(d) In addition to the foregoing scheduled annual and semi annual determinations of the Borrowing Base, the Required Lenders shall have the right to redetermine the Borrowing Base at their sole discretion at any time and from time to time but not more often than two (2) times every calendar year. If the Required Lenders shall elect to make a discretionary redetermination of the Borrowing Base pursuant to the provisions of this Section 2.07(d), the Borrower shall within thirty (30) days of receipt of a request therefor from the Administrative Agent, deliver to the Administrative Agent a Reserve Report in form and substance satisfactory to the Administrative Agent, prepared by the Borrower’s petroleum engineers containing information similar to the Reserve Reports delivered pursuant to Section 2.07(c), together with such updated engineering, production, operating and other data as the Administrative Agent, the Issuer or any Lender may reasonably request. The Administrative Agent shall have fifteen (15) days following receipt of such requested information to make an initial redetermination of the Borrowing Base, and the Administrative Agent and the Required Lenders shall approve and designate the new Borrowing Base in accordance with the procedures and standards described in Section 2.07(b).

(e) In addition to the foregoing determinations of the Borrowing Base, the Borrower may request a redetermination of the Borrowing Base at any time and from time to time but not more often than two (2) times every calendar year, by delivering a written request to the Administrative Agent, together with (a) an engineering fee in the aggregate amount of $2,500 for the account of the Administrative Agent in immediately available funds, and (b) a Reserve Report in form and substance satisfactory to the Administrative Agent, prepared by the Borrower’s petroleum engineers containing information similar to the Reserve Reports delivered pursuant to Section 2.07(c), together with such other updated engineering, production, operating and other data as the Administrative Agent, the Issuer or any Lender may reasonably request. Each such discretionary redetermination of the Borrowing Base shall be made in the same manner and in accordance with the procedures and standards set forth above by adjusting the Borrowing Base then in effect. The Administrative Agent shall have fifteen (15) days following receipt of such requested information to make an initial redetermination of the Borrowing Base, and the Administrative Agent and the Required Lenders shall approve and designate the new Borrowing Base in accordance with the procedures and standards described in Section 2.07(b).

(f) In addition to the Borrower’s right to request a discretionary Borrowing Base redetermination as set forth in Section 2.07(e), the Borrower may request a redetermination of the Borrowing Base at any time and from time to time upon the acquisition by the Borrower of additional Oil and Gas Properties, by delivering a written request to the Administrative Agent,

together with (a) an engineering fee in the aggregate amount of $2,500 for the account of the Administrative Agent in immediately available funds, (b) with respect to Oil and Gas Properties represented in the existing Borrowing Base, a Reserve Report in form and substance satisfactory to the Administrative Agent, prepared and delivered in accordance with Section 2.07(c), and (c) with respect to Oil and Gas Properties acquired since the most recent redetermination of the Borrowing Base, a Reserve Report in form and substance satisfactory to the Administrative Agent, prepared and delivered in accordance with Section 2.07(b). Each such redetermination of the Borrowing Base under this Section 2.07(f) shall be made in the same manner and in accordance with the procedures and standards set forth above by adjusting the Borrowing Base then in effect. The Administrative Agent shall have fifteen (15) days following receipt of such requested information to make an initial redetermination of the Borrowing Base, and the Administrative Agent and the Required Lenders shall approve and designate the new Borrowing Base in accordance with the procedures and standards described in Section 2.07(b).

(g) Notwithstanding anything to the contrary contained herein, upon the termination of the Gas Purchase Contract or the consummation of a Material Swap Transaction, the Required Lenders shall have the right to redetermine the Borrowing Base using information available to them, and the redetermined Borrowing Base shall become the new Borrowing Base immediately upon notice by the Administrative Agent to the Borrower, effective and applicable to the Borrower, the Administrative Agent, and each Lender on such date until the next redetermination or modification thereof hereunder (subject to the reduction described in Section 2.07(i)). The Borrowing Base will also be redetermined or adjusted in accordance with the provisions of Section 8.12(c) or Section 9.12(d).

(h) With the delivery of each Reserve Report, the Borrower shall provide to the Administrative Agent a certificate from a Responsible Officer certifying that, to the best of such Responsible Officer’s knowledge 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 Borrower or the Guarantors 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 9.03, (iii) 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 in excess of the volume specified in Section 7.20 with respect to their Oil and Gas Properties evaluated in such Reserve Report that would require the Borrower or any of its Subsidiaries to deliver Hydrocarbons either generally or produced from such Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor, (iv) none of their 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 all of its Oil and Gas Properties sold and in such detail as reasonably required by the Administrative Agent, (v) attached to the certificate is a list of all marketing agreements entered into subsequent to the later of the date hereof or the most recently delivered Reserve Report that the Borrower could reasonably be expected to have been obligated to list on Schedule 7.20 had such agreement been in effect on the date hereof and (vi) attached thereto is a schedule of the Oil and Gas Properties evaluated by such Reserve Report that are Mortgaged Properties and demonstrating the percentage of the present value that such Mortgaged Properties represent.

(i) Notwithstanding anything herein the contrary, in the event that the Borrower does not furnish any required Reserve Report within ten (10) days of date the required herein, the Administrative Agent and the Required Lenders may nonetheless designate the Borrowing Base from time to time thereafter until the Administrative Agent receives such Reserve Report, whereupon the Administrative Agent and the Required Lenders or all Lenders, as applicable, shall designate a new Borrowing Base in accordance with the general procedures outlined in Section 2.07(b).

Section 2.08 Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request any Issuer to issue Letters of Credit for its own account or for the account of the Borrower or any of its Subsidiaries, in a form reasonably acceptable to the Administrative Agent and such Issuer, at any time and from time to time during the Availability Period; provided that the Borrower may not request the issuance, amendment, renewal or extension of Letters of Credit hereunder if a Borrowing Base Deficiency exists at such time or would exist as a result thereof. 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, an Issuer 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 deliver as permitted by Section 12.01(a) (or transmit by electronic communication, if arrangements for doing so have been approved by the Issuer) to any Issuer and the Administrative Agent (not less than five (5) Business Days in advance of the requested date of issuance, amendment, renewal or extension) a notice in the form of Exhibit 2.08(b):

(i) requesting the issuance of a Letter of Credit or identifying the Letter of Credit issued by such Issuer to be amended, renewed or extended;

(iv) specifying the amount of such Letter of Credit;

(v) specifying 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; and

(vi) specifying the amount of the then effective Borrowing Base and whether a Borrowing Base Deficiency exists at such time, the current Total Revolving Credit Exposures (without regard to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit) and the pro forma Total Revolving Credit Exposures (giving effect to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit).

Each notice shall constitute a representation that after giving effect to the requested issuance, amendment, renewal or extension, as applicable, (i) the Letter of Credit Exposure shall not exceed the Letter of Credit Commitment and (ii) the Total Revolving Credit Exposures shall not exceed the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base.

If requested by any Issuer, the Borrower also shall submit a letter of credit application on such Issuer’s standard form in connection with any request for a Letter of Credit.

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is five Business Days prior to the Maturity Date.

(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 Issuer that issues such Letter of Credit or the Lenders, each Issuer that issues a Letter of Credit hereunder hereby grants to each Lender, and each Lender hereby acquires from such Issuer, 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 any Issuer that issues a Letter of Credit hereunder, such Lender’s Applicable Percentage of each Letter of Credit Disbursement made by such Issuer and not reimbursed by the Borrower on the date due as provided in Section 2.08(e), 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 Section 2.08(d) 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, the existence of a Borrowing Base Deficiency 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 any Issuer shall make any Letter of Credit Disbursement in respect of a Letter of Credit issued by such Issuer, the Borrower shall reimburse such Letter of Credit Disbursement by paying to the Administrative Agent an amount equal to such Letter of Credit Disbursement not later than 12:00 p.m., New York time, on the third day after such Letter of Credit Disbursement is made, if the Borrower shall have received notice of such Letter of Credit Disbursement prior to 10:00 a.m., New York time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 2:00 p.m., New York time, on (i) the third day after the Borrower receives such notice, if such notice is received prior to 10:00 a.m., New York time, on the day of receipt, or (ii) the Business Day immediately following the third day after the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that if such Letter of Credit Disbursement is not less than $1,000,000, the Borrower shall, subject to the conditions to

Borrowing set forth herein, be deemed to have requested, and the Borrower does hereby request under such circumstances, that such payment be financed with a Eurodollar Borrowing with an Interest Period of one month 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 Eurodollar Borrowing. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable Letter of Credit 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 2.05 with respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuer that issued such Letter of Credit 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 Section 2.08(e), the Administrative Agent shall distribute such payment to the Issuer that issued such Letter of Credit or, to the extent that Lenders have made payments pursuant to this Section 2.08(e) to reimburse such Issuer, then to such Lenders and such Issuer as their interests may appear. Any payment made by a Lender pursuant to this Section 2.08(e) to reimburse any Issuer for any Letter of Credit 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 Letter of Credit Disbursement. Any Letter of Credit Disbursement not reimbursed by the Borrower or funded as a Loan prior to 2:00 p.m., New York time, shall bear interest for such day at the ABR plus the Applicable Margin.

(f) Obligations Absolute. The obligation (a “Reimbursement Obligation”) of the Borrower to reimburse Letter of Credit Disbursements as provided in Section 2.08(e) 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, any Letter of Credit Agreement 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 any Issuer under a Letter of Credit issued by such Issuer against presentation of a draft or other document that does not comply with the terms of such Letter of Credit or any Letter of Credit Agreement, 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 2.08(f), constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor any Issuer, 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 any Issuer; provided that the foregoing shall not be construed to excuse any Issuer from liability to the Borrower to the extent of any direct damages (as opposed to 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 such Issuer’s failure to exercise commercially reasonable care when issuing Letters of Credit and determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof or suffered by Borrower as a result of Issuer’s gross negligence or willful misconduct. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of any Issuer (as finally determined by a court of competent jurisdiction), such Issuer shall be deemed to have exercised all requisite care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuer that issued such Letter of Credit 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. Each Issuer shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit issued by such Issuer. Such Issuer shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether such Issuer has made or will make a Letter of Credit Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse such Issuer and the Lenders with respect to any such Letter of Credit Disbursement.

(h) Interim Interest. If any Issuer shall make any Letter of Credit Disbursement, then, until the Borrower shall have reimbursed such Issuer for such Letter of Credit Disbursement (either with its own funds or a Borrowing under Section 2.08(e)), the unpaid amount thereof shall bear interest, for each day from and including the date such Letter of Credit Disbursement is made to but excluding the date that the Borrower reimburses such Letter of Credit Disbursement, at the rate per annum then applicable to ABR Loans. Interest accrued pursuant to this Section 2.08(h) shall be for the account of such Issuer, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.08(e) to reimburse such Issuer shall be for the account of such Lender to the extent of such payment.

(i) Replacement of an Issuer. Any Issuer may be replaced or resign at any time by written agreement among the Borrower, the Administrative Agent, such resigning or replaced Issuer and, in the case of a replacement, the successor Issuer. The Administrative Agent shall notify the Lenders of any such resignation or replacement of an Issuer. At the time any such resignation or replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the resigning or replaced Issuer pursuant to Section 3.04(b). In the case of the replacement of an Issuer, from and after the effective date of such replacement, (i) the successor Issuer shall have all the rights and obligations of the replaced Issuer under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to “Issuer” shall be deemed to refer to such successor or to any previous Issuer, or to such successor and all previous Issuers, as the context shall require. After the resignation or replacement of an Issuer hereunder, the resigning or replaced Issuer shall remain a party hereto and shall continue to have all the rights and obligations of an Issuer under this Agreement with respect to Letters of Credit issued by it prior to such resignation or replacement, but shall not be required to issue additional Letters of Credit.

(j) Cash Collateralization. If (i) any Event of Default shall occur and be continuing and the Borrower receives notice from the Administrative Agent or the Required Lenders demanding the deposit of cash collateral pursuant to this Section 2.08(j), or (ii) the Borrower is required to pay to the Administrative Agent the excess attributable to a Letter of Credit Exposure in connection with any prepayment pursuant to Section 3.03(c), then 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 (such account, the “Cash Collateral Account”, an amount in cash equal to, in the case of an Event of Default, the Letter of Credit Exposure, and in the case of a payment required by Section 3.03(c), the amount of such excess as provided in Section 3.03(c), 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 or any of its Subsidiaries described in Section 10.01(h) or Section 10.01(i). The Borrower hereby grants to the Administrative Agent, for the benefit of each Issuer 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. The Borrower’s obligation to deposit amounts pursuant to this Section 2.08(j) shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower or any of its Subsidiaries may now or hereafter have against any such beneficiary, any Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such deposit shall be held as collateral securing the payment and performance of the Borrower’s and any Guarantor’s obligations under this Agreement and the other Loan Documents. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account; provided that investments of funds in such account in investments permitted by Section 9.05(c) or (e) may be made at the option of the Borrower at its direction, risk and expense. 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, on a pro rata basis, each Issuer for Letter of Credit 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 Letter of Credit Exposure at such time or, if the maturity of the Loans has been accelerated, be applied to satisfy other obligations of the Borrower and the Guarantors, if any, under this Agreement or the other Loan Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, and the Borrower is not otherwise required to pay to the Administrative Agent the excess attributable to a Letter of Credit Exposure in connection with any prepayment pursuant to Section 3.03(c), then 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.

ARTICLE IV

PAYMENTS; PRO RATA TREATMENT; SHARING OF SET-OFFS.

Section 4.01 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) Payments by the Borrower. The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of Letter of Credit Disbursements, or of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 2:00 p.m., New York time, on the date when due (after giving effect to applicable grace periods) , in immediately available funds, without defense, deduction, recoupment, set-off or counterclaim. Fees, once paid, shall be fully earned and shall not be refundable under any circumstances. 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 specified in Section 12.01, except payments to be made directly to an Issuer as expressly provided herein and except that payments pursuant to Section 5.01, Section 5.02, Section 5.03 and Section 12.03 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) Application of Insufficient Payments. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed Letter of Credit 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 Letter of Credit Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed Letter of Credit Disbursements then due to such parties.

(c) Sharing of Payments by Lenders. 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 Letter of Credit Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in Letter of Credit 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 Letter of Credit 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 Letter of Credit 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 Section 4.01(c) 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 Letter of Credit Disbursements to any assignee or participant, other than to the Borrower or any Consolidated Subsidiary thereof (as to which the provisions of this Section 4.01(c) 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.

Section 4.02 Presumption of Payment by the Borrower. 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 any Issuer 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 such Issuer, 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 such Issuer, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or such Issuer 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.

Section 4.03 Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.05(b), Section 2.08(d), Section 2.08(e) or Section 4.02 then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

ARTICLE V

INCREASED COSTS; BREAK FUNDING PAYMENTS; TAXES; ILLEGALITY

Section 5.01 Increased Costs.

(a) Eurodollar Changes in Law. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve (including marginal, special, emergency or supplemental reserves), special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender for Eurocurrency liabilities under Regulation D of the Board (as the same may be amended, supplemented or replaced from time to time) or otherwise; or

(ii) impose on any Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender;

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 reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or otherwise), then the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If any Lender or any Issuer determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or such Issuer’s capital or on the capital of such Lender’s or such Issuer’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 such Issuer, to a level below that which such Lender or such Issuer or such Lender’s or such Issuer’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such Issuer’s policies and the policies of such Lender’s or such Issuer’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or such Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuer or such Lender’s or such Issuer’s holding company for any such reduction suffered.

(c) Certificates. A certificate of a Lender or any Issuer setting forth in reasonable detail the basis of its request and the amount or amounts necessary to compensate such Lender or such Issuer or its holding company, as the case may be, as specified in Section 5.01(a) or (b) shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or such Issuer, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Effect of Failure or Delay in Requesting Compensation. Failure or delay on the part of any Lender or any Issuer to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s or such Issuer’s right to demand such compensation, provided that no Lender may make any such demand more than 180 days after the Termination Date, nor for any amount which has accrued more than 270 days prior to such Lender or Issuer delivering the certificate required in Section 5.01(c).

Section 5.02 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 into an ABR Loan other than on the last day of the Interest Period applicable thereto, or (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the 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 which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market.

A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section 5.02 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 5.03 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower or any Guarantor under any Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower or any Guarantor shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 5.03(a)), the Administrative Agent, Lender or Issuer (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower or such Guarantor shall make such deductions and (iii) the Borrower or such Guarantor shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Lender and each Issuer, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or such Issuer, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 5.03) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate of the Administrative Agent, a Lender or an Issuer as to the basis of such Indemnified Taxes and Other Taxes and the amount of such payment or liability under this Section 5.03 shall be delivered to the Borrower and shall be conclusive absent manifest error.

(d) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower or a Guarantor 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.

(e) Foreign Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement or any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate.

Section 5.04 Designation of Different Lending Office. If any Lender requests compensation under Section 5.01, 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 5.03, 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 (a) would eliminate or reduce amounts payable pursuant to Section 5.01 or Section 5.03, as the case may be, in the future and (b) 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.

Section 5.05 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its applicable lending office to honor its obligation to make or maintain Eurodollar Loans either generally or having a particular Interest Period hereunder, then (a) such Lender shall promptly notify the Borrower and the Administrative Agent thereof and such Lender’s obligation to make such Eurodollar Loans shall be suspended (the “Affected Loans”) until such time as such Lender may again make and maintain such Eurodollar Loans and (b) all Affected Loans which would otherwise be made by

such Lender shall be made instead as ABR Loans (and, if such Lender so requests by notice to the Borrower and the Administrative Agent, all Affected Loans of such Lender then outstanding shall be automatically converted into ABR Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into) ABR Loans, all payments of principal which would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its ABR Loans.

Section 5.06 Replacement of a Lender. If any Lender (an “Affected Lender”) (a) makes a demand upon the Borrower for amounts pursuant to Section 5.01 (and the payment of such amounts are, and are likely to continue to be, materially more onerous in the reasonable judgment of the Borrower than with respect to the other Lenders) or (b) in connection with any proposed increase in the Borrowing Base pursuant to Section 2.07 refuses to consent to such increase, the Borrower may, within 30 days of receipt by the Borrower of such demand, give notice (a “Replacement Notice”) in writing to the Administrative Agent and such Affected Lender of its intention to cause such Affected Lender to sell all of its Loans, Loan Commitments and/or Notes to an Eligible Assignee (a “Replacement Lender”) designated in such Replacement Notice; provided, however, that no Replacement Notice may be given by the Borrower and no Lender may be replaced pursuant to this Section 5.06 if (i) such replacement conflicts with any applicable law or regulation, (ii) any Event of Default shall have occurred and be continuing at the time of such replacement or (iii) prior to any such replacement, such Affected Lender shall have taken any necessary action under Section 5.04 (if applicable) so as to eliminate the continued need for payment of amounts owing pursuant to Section 5.01 or shall have waived its right to payment of the specific amounts that give rise or would give rise to such Replacement Notice (it being understood for sake of clarity that the Affected Lender shall be under no obligation to waive such rights to payment and that such Affected Lender, if it is replaced in accordance with this Section 5.06, shall be entitled to be reimbursed for all breakage losses in connection with such replacement). If the Administrative Agent shall, in the exercise of its reasonable discretion and within 30 days of its receipt of such Replacement Notice, notify the Borrower and such Affected Lender in writing that the Replacement Lender is satisfactory to the Administrative Agent (such consent not being required where the Replacement Lender is already a Lender or an Affiliate of a Lender or an Eligible Assignee), then such Affected Lender shall, subject to the payment of any amounts due pursuant to Section 5.02, assign, in accordance with Section 12.04, all of its Loan Commitments, Loans, Notes (if any), and other rights and obligations under this Agreement and all other Loan Documents (including Reimbursement Obligations, if applicable) designated in the replacement notice to such Replacement Lender; provided, however, that (A) such assignment shall be without recourse, representation or warranty and shall be on terms and conditions reasonably satisfactory to such Affected Lender and such Replacement Lender, (B) the purchase price paid by such Replacement Lender shall be in the amount of such Affected Lender’s Loans designated in the Replacement Notice, and/or its Percentage of outstanding Reimbursement Obligations, as applicable, together with all accrued and unpaid interest and fees in respect thereof, plus all other amounts (including the amounts demanded and unreimbursed under Section 5.01) and (C) the Borrower shall pay to the Affected Lender and the Administrative Agent all reasonable out-of-pocket expenses incurred by the Affected Lender and the Administrative Agent in connection with such assignment and assumption (including the processing fees described in Section 12.04). If the Administrative Agent fails to notify Borrower within 30 days of its receipt of such Replacement Notice that such Replacement Lender is satisfactory, then such Replacement Lender shall be deemed satisfactory

to the Administrative Agent. Upon the effective date of an assignment described above, the Replacement Lender shall become a “Lender” for all purposes under the Loan Documents. Each Lender hereby grants to the Administrative Agent an irrevocable power of attorney (which power is coupled with an interest) to execute and deliver, on behalf of such Lender as assignor, any assignment agreement necessary to effectuate any assignment of such Lender’s interests hereunder in the circumstances contemplated by this Section 5.06.

Specifically in connection with the foregoing, except as could not reasonably be expected to have a Material Adverse Effect, (a) no Oil and Gas Property is subject to having allowable production reduced below the full and regular allowable (including the maximum permissible tolerance) because of any overproduction (whether or not the same was permissible at the time) and (b) none of the xxxxx comprising a part of the Oil and Gas Properties (or Properties unitized therewith) is deviated from the vertical more than the maximum permitted by Government Requirements, and such xxxxx are, in fact, bottomed under and are producing from, and the well bores are wholly within, the Oil and Gas Properties (or in the case of xxxxx located on Properties unitized therewith, such unitized Properties). All pipelines, xxxxx, gas processing plants, platforms and other material improvements, fixtures and

equipment owned in whole or in part by the Borrower or any of its Subsidiaries that are necessary to conduct normal operations are being maintained in a state adequate to conduct normal operations, and with respect to such of the foregoing which are operated by the Borrower or any of its Subsidiaries, in a manner consistent with the Borrower’s or its Subsidiaries’ past practices (other than those the failure of which to maintain in accordance with this Section 7.17 could not reasonably be expect to have a Material Adverse Effect).

Section 7.20 Gas Imbalances, Prepayments. As of the date hereof, except as set forth on Schedule 7.20 or on the most recent certificate delivered pursuant to Section 2.07(c), on a net basis there are no gas imbalances, take or pay or other prepayments which would require the Borrower or any of its Subsidiaries to deliver, in the aggregate, three percent (3%) or more of the monthly production from Hydrocarbons produced from the Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor.

Section 7.21 Marketing of Production. Except for the Gas Purchase Contract and for contracts listed and in effect on the date hereof on Schedule 7.21, and thereafter either disclosed in writing to the Administrative Agent or included in the most recently delivered Reserve Report (with respect to all of which contracts the Borrower represents that it or the Guarantors are receiving a price for all production sold thereunder which is computed substantially in accordance with the terms of the relevant contract and are not having deliveries curtailed substantially below the subject Property’s delivery capacity), no material agreements exist which are not cancelable on 60 days notice or less without penalty or detriment for the sale of production from the Borrower’s or the Guarantors’ Hydrocarbons (including, without limitation, calls on or other rights to purchase, production, whether or not the same are currently being exercised) that pertain to the sale of production at a fixed price.

Section 7.22 Swap Agreements. Schedule 7.22, as of the date hereof, and after the date hereof, each report required to be delivered by the Borrower pursuant to Section 8.01(e), sets forth, a true and complete list of all Swap Agreements of the Borrower and each of its Subsidiaries, the material terms thereof (including the type, term, effective date, termination date and notional amounts or volumes), the net marked-to-market value thereof, all credit support agreements relating thereto (including any margin required or supplied) and the counterparty to each such agreement.

Section 7.23 Use of Loans and Letters of Credit. The proceeds of the Loans and the Letters of Credit shall be used (a) for the acquisition, exploration, operation, maintenance and development of Oil and Gas Properties and related properties, facilities, rights and interests, (b) for general corporate purposes, including Restricted Payments, provided that if the Borrowing Base Utilization Percentage is equal to or exceeds 90% before or after giving effect to the requested Loan or Letter of Credit, then no proceeds of any Loan or any Letter of Credit may be used to fund Restricted Payments under Section 9.04, (c) for the payment of expenses incurred by the Borrower in connection with the Transactions, (d) to provide working capital, and (d) for the issuance of Letters of Credit. The Borrower and its Subsidiaries are not engaged principally, or as one of its or their important activities, in the business of extending credit for the purpose, whether immediate, incidental or ultimate, of buying or carrying margin stock (within the meaning of Regulation T, U or X of the Board). No part of the proceeds of any Loan or Letter of Credit will be used for any purpose which violates the provisions of Regulations T, U or X of the Board.

Section 7.24 Solvency. After giving effect to the transactions contemplated hereby, (a) the aggregate assets (after giving effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any similar arrangement), at a fair valuation, of the Borrower and the Guarantors, taken as a whole, will exceed the aggregate Debt of the Borrower and the Guarantors on a consolidated basis, as the Debt becomes absolute and matures, (b) each of the Borrower and the Guarantors will not have incurred or intended to incur, and will not believe that it will incur, Debt beyond its ability to pay such Debt (after taking into account the timing and amounts of cash to be received by each of the Borrower and the Guarantors and the amounts to be payable on or in respect of its liabilities, and giving effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any similar arrangement) as such Debt becomes absolute and matures and (c) each of the Borrower and the Guarantors will not have (and will have no reason to believe that it will have thereafter) unreasonably small capital for the conduct of its business.

The Administrative Agent will promptly send the Borrower any financing or continuation statements it files and the Administrative Agent will promptly send the Borrower the filing or recordation information with respect thereto.

Section 8.12 Title Information.

(a) On or before the delivery to the Administrative Agent and the Lenders of each Reserve Report required by Section 2.07(b), to the extent requested by the Administrative Agent, the Borrower will deliver title information in form and substance acceptable to the Administrative Agent covering enough of the Oil and Gas Properties evaluated by such Reserve Report that were not included in the immediately preceding Reserve Report, so that the Administrative Agent shall have received together with title information previously delivered to the Administrative Agent, satisfactory title information on at least 85% of the total value of the Oil and Gas Properties evaluated by such Reserve Report.

(b) If the Borrower has provided title information for additional Properties under Section 2.07(b), 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) which are not permitted by Section 9.03 raised by such information, (ii) substitute acceptable Mortgaged Properties with no title defects or exceptions except for Excepted Liens (other than Excepted Liens described in clauses (e), (g) and (h) of such definition) having an equivalent value or (iii) deliver title information in form and substance reasonably acceptable to the Administrative Agent so that the Administrative Agent shall have received, together with title information previously delivered to the Administrative Agent, reasonably satisfactory title information on at least 85% of the value of the Oil and Gas Properties evaluated by such Reserve Report.

(c) If the Borrower is unable to cure any title defect requested by the Administrative Agent or the Lenders to be cured within the 60-day period or the Borrower does not comply with the requirements to provide acceptable title information covering 85% of the value of the Oil and Gas Properties evaluated in the most recent Reserve Report, such default shall not be a Default, but instead the Administrative Agent and/or the Required 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 Required Lenders are not reasonably satisfied with title to any Mortgaged Property after the 60-day period has elapsed, such unacceptable Mortgaged Property shall not count towards the 85% requirement, and the Administrative Agent may send a notice to the Borrower and the Lenders that the then outstanding Borrowing Base shall be reduced by an amount as determined by the Required Lenders to cause the Borrower to be in compliance with the requirement to provide acceptable title information on 85% of the value of the Oil and Gas Properties. This new Borrowing Base shall become effective immediately after receipt of such notice.

Section 8.13 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 Mortgaged Properties to ascertain whether the Mortgaged Properties represent at least 85% of the total value of the Oil and Gas Properties evaluated in the most recently completed Reserve Report after giving effect to exploration and production activities, acquisitions, dispositions and production. In the event that the Mortgaged Properties do not represent at least 85% of such total value, then the

Borrower shall, and shall cause its Subsidiaries to, grant to the Administrative Agent or its designee as security for the Indebtedness a first-priority Lien interest (provided the Excepted Liens of the type described in clauses (a) to (d) and (f) of the definition thereof may exist, but subject to the provisos at the end of such definition) on additional Oil and Gas Properties not already subject to a Lien of the Security Instruments such that after giving effect thereto, the Mortgaged Properties will represent at least 85% of such total value. All such Liens will be created and perfected by and in accordance with the provisions of deeds of trust, security agreements and financing statements or other Security Instruments, all in form and substance reasonably satisfactory to the Administrative Agent or its designee and in sufficient executed (and acknowledged where necessary or appropriate) counterparts for recording purposes. In order to comply with the foregoing, if any Subsidiary places a Lien on its Oil and Gas Properties and such Subsidiary is not a Guarantor, then it shall become a Guarantor and comply with Section 8.13(b).

(b) In the event that (i) the Borrower determines that any Subsidiary is a Material Domestic Subsidiary or (ii) any Domestic Subsidiary incurs or guarantees any Debt, then the Borrower shall promptly cause such Subsidiary to guarantee the Indebtedness pursuant to the Guarantee Agreement. In connection with any such guaranty, the Borrower shall, or shall cause such Subsidiary to, (A) execute and deliver a supplement to the Guarantee Agreement executed by such Subsidiary, (B) pledge all of the Equity Interests of such Subsidiary (including, without limitation, delivery of original stock certificates evidencing the Equity Interests of such Subsidiary (if such interests are certificated), together with an appropriate undated stock powers for each certificate duly executed in blank by the registered owner thereof) and (C) execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent or its designee.

With respect to each Plan, if any (other than a Multiemployer Plan), the Borrower will, and the Borrower will cause each of its Subsidiaries to, (i) satisfy in full and in a timely manner, without incurring any late payment or underpayment charge or penalty and without giving rise to any lien, all of the contribution and funding requirements of section 412 of the Code (determined without regard to subsections (d), (e), (f) and (k) thereof) and of section 302 of ERISA (determined without regard to sections 303, 304 and 306 of ERISA), and (ii) pay, or cause to be paid, to the PBGC in a timely manner, without incurring any late payment or underpayment charge or penalty, all premiums required pursuant to sections 4006 and 4007 of ERISA.

Section 8.16 Title. With respect to Oil and Gas Properties acquired after the Closing Date or not previously included in the Borrowing Base, and to the extent necessary to allow the Administrative Agent to achieve the percentage described in the preceding sentence, the Borrower shall from time to time upon the reasonable request of the Administrative Agent, take such actions and execute and deliver such documents and instruments as the Administrative Agent shall require to ensure that the Administrative Agent shall, at all times, have received satisfactory title opinions (including, if requested, supplemental or new title opinions addressed to it), title reports, or other title due diligence, which title diligence shall be in form and substance reasonably acceptable to the Administrative Agent and shall include information regarding the before payout and after payout ownership interests held by the Borrower and its Subsidiaries, for all xxxxx located on the Oil and Gas Properties shown in the most recent Reserve Report.

Section 8.17 Board Composition. The Permitted Holders shall at all times have the right to appoint all of the Class A Managers pursuant to Section 11.8(d) of the Second Amended and Restated Operating Agreement of the Borrower as filed with the SEC on September [28], 2006.

ARTICLE XI

THE ADMINISTRATIVE AGENT

Section 11.01 Appointment; Powers. Each of the Lenders and each Issuer hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof and the other Loan Documents, together with such actions and powers as are reasonably incidental thereto.

Section 11.02 Duties and Obligations of Administrative Agent. The Administrative Agent shall have no duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing (the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law; rather, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties), (b) the Administrative Agent shall have no duty to take any discretionary action or exercise any discretionary powers, except as provided in Section 11.03, and (c) except as expressly set forth herein, the Administrative Agent shall have no duty to disclose, and shall not be liable for the failure to disclose, any information relating to the 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 be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document

delivered hereunder or under any other Loan Document or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or in any other Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, (v) the satisfaction of any condition set forth in ARTICLE VI or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent, (vi) the existence, value, perfection or priority of any collateral security or the financial or other condition of the Borrower and its Subsidiaries or any other obligor or guarantor, or (vii) any failure by the Borrower or any other Person (other than itself) to perform any of its obligations hereunder or under any other Loan Document or the performance or observance of any covenants, agreements or other terms or conditions set forth herein or therein. For purposes of determining compliance with the conditions specified in ARTICLE VI, each Lender shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received written notice from such Lender prior to the proposed closing date specifying its objection thereto.

Section 11.03 Action by Agent. The Administrative Agent shall have no duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise in writing as directed by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) and in all cases the Administrative Agent shall be fully justified in failing or refusing to act hereunder or under any other Loan Documents unless it shall (a) receive written instructions from the Required Lenders or the Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) specifying the action to be taken and (b) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of taking or continuing to take any such action. The instructions as aforesaid and any action taken or failure to act pursuant thereto by the Administrative Agent shall be binding on all of the Lenders. If a Default has occurred and is continuing, then the Administrative Agent shall take such action with respect to such Default as shall be directed by the requisite Lenders in the written instructions (with indemnities) described in this Section 11.03, provided that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interests of the Lenders. In no event, however, shall the Administrative Agent be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, the Loan Documents or applicable law. If a Default has occurred and is continuing, the Syndication Agent shall have no obligation to perform any act in respect thereof. No Agent shall be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders or the Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02), and otherwise the Administrative Agent shall not be liable for any action taken or not taken by it hereunder or under any other Loan Document or under any other document or instrument referred to or provided for herein or therein or in connection herewith or therewith INCLUDING ITS OWN ORDINARY NEGLIGENCE, except for its own gross negligence or willful misconduct.

Section 11.04 Reliance by Agent. Each 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. Each 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 and each of the Borrower, the Lenders and each Issuer hereby waives the right to dispute such Agent’s record of such statement, except in the case of gross negligence or willful misconduct by such Agent. Each 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. The Agents may deem and treat the payee of any Note as the holder thereof for all purposes hereof unless and until a written notice of the assignment or transfer thereof permitted hereunder shall have been filed with the Administrative Agent.

Section 11.05 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 Sections of this ARTICLE XI 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 Agent.

Section 11.06 Resignation or Removal of Agents. Subject to the appointment and acceptance of a successor Agent as provided in this Section 11.06, any Agent may resign at any time by notifying the Lenders, each Issuer and the Borrower, and any Agent may be removed at any time with or without cause by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right, subject to the consent of the Borrower, such consent not to be unreasonably withheld or delayed, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation or removal of the retiring Agent, then the retiring Agent may, on behalf of the Lenders and each Issuer, appoint a successor Agent. Upon the acceptance of its appointment as Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Agent’s resignation hereunder, the provisions of this ARTICLE XI and Section 12.03 shall continue in effect for the benefit of such retiring 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 Agent.

Section 11.07 Agents and Lenders. Each bank serving as an Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the

same as though it were not an Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not an Agent hereunder.

Section 11.08 No Reliance. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent, any other Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and each other Loan Document to which it is a party. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent, any other Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document, any related agreement or any document furnished hereunder or thereunder. The Agents shall not be required to keep themselves informed as to the performance or observance by the Borrower or any of its Subsidiaries of this Agreement, the Loan Documents or any other document referred to or provided for herein or to inspect the Properties or books of the Borrower or its Subsidiaries. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder, no Agent and no Arranger shall have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of the Borrower (or any of its Affiliates) which may come into the possession of such Agent or any of its Affiliates. In this regard, each Lender acknowledges that Pillsbury Xxxxxxxx Xxxx Xxxxxxx LLP is acting in this transaction as special counsel to the Administrative Agent only, except to the extent otherwise expressly stated in any legal opinion or any Loan Document. Each other party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein.

Section 11.09 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Borrower or any of its Subsidiaries, the Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other Indebtedness that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under Section 12.03) allowed in such judicial proceeding; and

(b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, in the event

that the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Section 12.03.

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

Section 11.10 Authority of Administrative Agent to Release Collateral and Liens. Each Lender and each Issuer hereby authorizes the Administrative Agent to release any collateral that is permitted to be sold or released pursuant to the terms of the Loan Documents. Each Lender and each Issuer hereby authorizes the Administrative Agent to execute and deliver to the Borrower, at the Borrower’s sole cost and expense, any and all releases of Liens, termination statements, assignments or other documents reasonably requested by the Borrower in connection with any sale or other disposition of Property to the extent such sale or other disposition is permitted by the terms of Section 9.12 or is otherwise authorized by the terms of the Loan Documents.

Section 11.11 The Arrangers and the Syndication Agent. The Arrangers and the Syndication Agent shall have no duties, responsibilities or liabilities under this Agreement and the other Loan Documents other than its duties, responsibilities and liabilities in its capacity as a Lender hereunder to the extent it is a party to this Agreement as a Lender.

Section 12.02 Waivers; Amendments.

(a) No failure on the part of the Administrative Agent, any other Agent, any Issuer or any Lender to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege, or any abandonment or discontinuance of steps to enforce such right, power or privilege, under any of the Loan Documents shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under any of the Loan Documents preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies of the Administrative Agent, any other Agent, each Issuer and the Lenders hereunder and under the other Loan Documents 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 any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by Section 12.02(b), 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 other Agent, any Lender or any Issuer may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any provision hereof nor any Security Instrument nor any provision thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Maximum Credit Amount of any Lender without the written consent of such Lender, (ii) increase the Borrowing Base without the written consent of each Lender, decrease or maintain the Borrowing Base without the consent of the Required Lenders, or modify in any manner Section 2.07 without the consent of each Lender, (iii) reduce the principal amount of any Loan or Letter of Credit Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, or reduce any other Indebtedness hereunder or under any other Loan Document, without the written consent of each Lender affected thereby, (iv) postpone the scheduled date of payment of the principal amount of any Loan or Letter of Credit Disbursement, or any interest thereon, or any fees payable hereunder, or any other Indebtedness hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Termination Date or the Maturity Date without the written consent of each Lender affected thereby, (v) change Section 4.01(b) or Section 4.01(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (vi) waive or amend Section 6.01, Section 10.02(c) or Section 8.13 or change the definition of the terms “Domestic Subsidiary”, “Foreign Subsidiary”, “Material Domestic Subsidiary” or “Subsidiary”, without the written consent of each Lender, (vii) release any Guarantor (except as set forth in the Guarantee Agreement), release all or substantially all of the collateral (other than as provided in Section 11.09), or reduce the percentage set forth in Section 8.13(a) to less than 80%, without the written consent of each Lender, or (viii) change any of the provisions of this Section 12.02(b) or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of

Lenders required to waive, amend or modify any rights hereunder or under any other Loan Documents or make any determination or grant any consent hereunder or any other Loan Documents, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, any other Agent, or any Issuer hereunder or under any other Loan Document without the prior written consent of the Administrative Agent, such other Agent or such Issuer, as the case may be. Notwithstanding the foregoing, any supplement to Schedule 7.14 (Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental schedule clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders.

Section 12.03 Expenses, Indemnity; Damage Waiver.

(a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent, including, without limitation, the reasonable fees, charges and disbursements of counsel and other outside consultants for the Administrative Agent, the reasonable travel, photocopy, mailing, courier, telephone and other similar expenses and, in connection with the syndication of the credit facilities provided for herein, the preparation, negotiation, execution, delivery and administration (both before and after the execution hereof and including advice of counsel to the Administrative Agent as to the rights and duties of the Administrative Agent and the Lenders with respect thereto) of this Agreement and the other Loan Documents and any amendments, modifications or waivers of or consents related to the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all out-of-pocket costs, expenses, Taxes, assessments and other charges incurred by any Agent or any Lender in connection with any filing, registration, recording or perfection of any security interest contemplated by this Agreement or any Security Instrument or any other document referred to therein, (iii) all reasonable out-of-pocket expenses incurred by each Issuer in connection with the amendment of any Letter of Credit issued by such Issuer or any demand for payment thereunder, (iv) all reasonable out-of-pocket expenses incurred by any Agent, any Issuer or any Lender, including the fees, charges and disbursements of one (1) legal counsel for Agent, Issuer and Lenders, in connection with the enforcement or protection of its rights in connection with this Agreement or any other Loan Document, including its rights under this Section 12.03, or in connection with the Loans made or Letters of Credit issued hereunder, including, without limitation, all such reasonable out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit; provided, however, Borrower shall be obligated to pay such expenses for only one counsel.

(b) THE BORROWER SHALL INDEMNIFY EACH AGENT, THE ARRANGERS, EACH ISSUER AND EACH LENDER, AND THE AFFILIATES, DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS 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, 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 OTHER LOAN DOCUMENT CONTEMPLATED HEREBY, THE PERFORMANCE BY THE PARTIES HERETO OR THE PARTIES TO ANY OTHER LOAN DOCUMENT OF THEIR RESPECTIVE OBLIGATIONS HEREUNDER OR THEREUNDER OR THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREBY OR BY ANY OTHER LOAN DOCUMENT, (ii) THE FAILURE OF THE BORROWER OR ANY OF ITS SUBSIDIARIES TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING THIS AGREEMENT, OR WITH ANY GOVERNMENTAL REQUIREMENT, (iii) ANY INACCURACY OF ANY REPRESENTATION OR ANY BREACH OF ANY WARRANTY OR COVENANT OF THE BORROWER OR ANY GUARANTOR SET FORTH IN ANY OF THE LOAN DOCUMENTS OR ANY INSTRUMENTS, DOCUMENTS OR CERTIFICATIONS DELIVERED IN CONNECTION THEREWITH, (iv) ANY LOAN OR LETTER OF CREDIT OR THE USE OF THE PROCEEDS THEREFROM, INCLUDING, WITHOUT LIMITATION, ANY REFUSAL BY ANY ISSUER TO HONOR A DEMAND FOR PAYMENT UNDER A LETTER OF CREDIT ISSUED BY SUCH ISSUER IF THE DOCUMENTS PRESENTED IN CONNECTION WITH SUCH DEMAND DO NOT STRICTLY COMPLY WITH THE TERMS OF SUCH LETTER OF CREDIT, (v) THE OPERATIONS OF THE BUSINESS OF THE BORROWER AND ITS SUBSIDIARIES BY THE BORROWER AND ITS SUBSIDIARIES, (vi) ANY ASSERTION BY A THIRD PARTY THAT THE LENDERS WERE NOT ENTITLED TO RECEIVE THE PROCEEDS RECEIVED PURSUANT TO THE SECURITY INSTRUMENTS, (iii) THE BREACH OR NON-COMPLIANCE BY THE BORROWER OR ANY OF ITS SUBSIDIARIES WITH ANY ENVIRONMENTAL LAW APPLICABLE TO THE BORROWER OR ANY OF ITS SUBSIDIARIES, (iv) THE PRESENCE, USE, RELEASE, STORAGE, TREATMENT, DISPOSAL, GENERATION, THREATENED RELEASE, TRANSPORT, ARRANGEMENT FOR TRANSPORT OR ARRANGEMENT FOR DISPOSAL OF OIL, OIL AND GAS WASTES, SOLID WASTES OR HAZARDOUS SUBSTANCES ON OR AT ANY OF THE PROPERTIES OWNED OR OPERATED BY THE BORROWER OR ANY OF ITS SUBSIDIARIES IN VIOLATION OF ENVIRONMENTAL LAWS OR ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF HAZARDOUS MATERIALS ON OR FROM ANY PROPERTY OWNED OR OPERATED BY THE BORROWER OR ANY OF ITS SUBSIDIARIES IN VIOLATION OF ENVIRONMENTAL LAWS, (v) ANY ENVIRONMENTAL LIABILITY RELATED IN ANY WAY TO THE BORROWER OR ANY OF ITS SUBSIDIARIES, OR (vi) ANY OTHER VIOLATION OF ENVIRONMENTAL LAWS OR LAWS RELATING TO ANY HEALTH OR SAFETY CONDITION IN CONNECTION WITH THE LOAN DOCUMENTS, OR (vii) 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, AND SUCH INDEMNITY SHALL EXTEND TO EACH INDEMNITEE NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF ONE OR MORE OF THE INDEMNITEES OR BY REASON OF STRICT LIABILITY IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNITEES; 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.

(c) To the extent that the Borrower fails to pay any amount required to be paid by it to such Agent or any Issuer under Section 12.03(a) or (b), each Lender severally agrees to pay to such Agent or such Issuer, 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 such Agent or such Issuer in its capacity as such.

(d) To the extent permitted by applicable law, the Borrower shall not assert, and 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, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

(e) All amounts due under this Section 12.03 shall be payable within ten (10) Business Days of written demand therefor.

Section 12.04 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 any Issuer that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by 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 12.04. 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 any Issuer that issues any Letter of Credit), Participants (to the extent provided in Section 12.04(c)) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, each Issuer 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 Section 12.04(b)(ii), any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement to an Eligible Assignee (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 or an Affiliate of a Lender or, if an Event of Default has occurred and is continuing, to any other Eligible Assignee; and

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

(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 or an assignment of the entire remaining amount of the assigning Lender’s Commitment, the amount of the Commitment 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.

(iii) Subject to Section 12.04(b)(iv) and the acceptance and recording thereof, 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 Section 5.01, Section 5.02, Section 5.03 and Section 12.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.04 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 Section 12.04(c).

(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

delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Maximum Credit Amount of, and principal amount of the Loans and Letter of Credit 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, each Issuer 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, any Issuer and any Lender, at any reasonable time and from time to time upon reasonable prior notice. In connection with any changes to the Register, if necessary, the Administrative Agent will reflect the revisions on Annex I and forward a copy of such revised Annex I to the Borrower, each Issuer and each Lender.

(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 Section 12.04(b) and any written consent to such assignment required by Section 12.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 12.04(b).

(c) (i) Any Lender may, without the consent of the Borrower the Administrative Agent or any Issuer, sell participations to one or more banks or other entities (a “Participant”) 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, each Issuer 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 proviso to Section 12.02 that affects such Participant. In addition such agreement must provide that the Participant be bound by the provisions of Section 12.03. Subject to Section 12.04(c)(ii), the Borrower agrees that each Participant shall be entitled to the benefits of Section 5.01, Section 5.02 and Section 5.03 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.04(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.08 as though it were a Lender, provided such Participant agrees to be subject to Section 4.01(c) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 5.01 or Section 5.03 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A

Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 5.03 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 5.03(e) as though it were a Lender.

(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 any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section 12.04(d) 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 12.05 Survival; Revival; Reinstatement.

(a) All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document 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, any other Agent, any Issuer 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 Section 5.01, Section 5.02, Section 5.03 and Section 12.03 and ARTICLE XI 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, any other Loan Document or any provision hereof or thereof.

(b) To the extent that any payments on the Indebtedness or proceeds of any collateral are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law, common law or equitable cause, then to such extent, the Indebtedness so satisfied shall be revived and continue as if such payment or proceeds had not been received and the Administrative Agent’s and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and each Loan Document shall continue in full force and effect. In such event, each Loan Document shall be automatically reinstated and the Borrower shall take such action as may be reasonably requested by the Administrative Agent and the Lenders to effect such reinstatement.

Section 12.06 Counterparts; Integration; Effectiveness.

(a) 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 contract.

(b) 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 thereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof and thereof. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES HERETO AND THERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

(c) Except as provided in Section 6.01, 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 shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 12.07 Severability .

Section 12.11 Confidentiality. Each of the Agents, each Issuer and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that 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), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement or any other Loan Document, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section 12.11, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any Swap Agreement relating to the Borrower and their obligations, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section 12.11 or (ii) becomes available to the Administrative Agent, any Issuer or any Lender on a nonconfidential basis from a source other than the Borrower. For the purposes of this Section 12.11, “Information” means all information received from the Borrower or any of its Subsidiaries relating to the Borrower or any of its Subsidiaries and their businesses, other than any such information that is available to the Administrative Agent, any Issuer or any Lender on a nonconfidential basis prior to disclosure by the Borrower or any of its Subsidiaries; provided that, in the case of information received from the Borrower, or any of its Subsidiaries after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section 12.11 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.

Section 12.12 Maximum Interest. It is the intention of the parties hereto to conform strictly to applicable usury laws and, anything herein to the contrary notwithstanding, the Obligations of the Borrower to each Lender under this Agreement shall be subject to the limitation that payments of interest shall not be required to the extent that receipt thereof would be contrary to provisions of law applicable to such Lender limiting rates of interest that may be charged or collected by such Lender. Accordingly, if the transactions contemplated hereby would be usurious under applicable law (including the Federal and state laws of the United States of America, or of any other jurisdiction whose laws may be mandatorily applicable) with respect to a Lender, then, in that event, notwithstanding anything to the contrary in this Agreement, it is agreed as follows: (a) the provisions of this Section 12.12 shall govern and control; (b) the aggregate of all consideration that constitutes interest under applicable law that is contracted for, charged or received under this Agreement, or under any other Loan Document or otherwise in connection with this Agreement by such Lender shall under no circumstances exceed the maximum amount of interest allowed by applicable law (such maximum lawful interest rate, if any, with respect to such Lender herein called the “Highest Lawful Rate”), and any excess shall be credited to the Borrower by such Lender (or, if such consideration shall have been paid in full, such excess promptly refunded to the Borrower); (c) all sums paid, or agreed to be paid, to such Lender for the use, forbearance and detention of the indebtedness of the

Borrower to such Lender hereunder shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in full so that the actual rate of interest is uniform throughout the full term thereof; and (d) if at any time the interest provided pursuant to Section 3.02, together with any other fees and expenses payable pursuant to this Agreement and the other Loan Documents and deemed interest under applicable law, exceeds that amount that would have accrued at the Highest Lawful Rate, then the amount of interest and any such fees to accrue to such Lender pursuant to this Agreement shall be limited, notwithstanding anything to the contrary in this Agreement, to that amount that would have accrued at the Highest Lawful Rate, but any subsequent reductions, as applicable, shall not reduce the interest to accrue to such Lender pursuant to this Agreement below the Highest Lawful Rate until the total amount of interest accrued pursuant to this Agreement and such fees deemed to be interest equals the amount of interest that would have accrued to such Lender if a varying rate per annum equal to the interest provided pursuant to Section 3.02 had at all times been in effect, plus the amount of fees that would have been received but for the effect of this Section 12.12.

Section 12.13 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.”

Section 12.14 Collateral Matters; Swap Agreements. The benefit of the Security Instruments and of the provisions of this Agreement relating to any collateral securing the Indebtedness shall also extend to and be available to those Lenders or their Affiliates which are counterparties to any Swap Agreement with the Borrower or any of its Subsidiaries on a pro rata basis in respect of any obligations of the Borrower or any of its Subsidiaries which arise under any such Swap Agreement while such Person or its Affiliate is a Lender, but only while such Person or its Affiliate is a Lender, including any Swap Agreements between such Persons in existence prior to the date hereof. No Lender or any Affiliate of a Lender shall have any voting rights under any Loan Document as a result of the existence of obligations owed to it under any such Swap Agreements.

Section 12.15 No Third Party Beneficiaries. This Agreement, the other Loan Documents, and the agreement of the Lenders to make Loans and the Issuer to issue, amend, renew or extend Letters of Credit hereunder are solely for the benefit of the Borrower, and no other Person (including, without limitation, any Subsidiary of the Borrower, any obligor, contractor, subcontractor, supplier or materialsman) shall have any rights, claims, remedies or privileges hereunder or under any other Loan Document against the Administrative Agent, any other Agent, the Issuer or any Lender for any reason whatsoever. There are no third party beneficiaries.

L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act.
