Notwithstanding anything to the contrary in this Agreement, all borrowings, conversions and continuations of Eurodollar Loans hereunder and all selections of Interest Periods hereunder shall be in such amounts and be made pursuant to such elections so that, (a) after giving effect thereto, the aggregate principal amount of the Eurodollar Loans comprising each Eurodollar Tranche shall be equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof and (b) no more than ten (10) Eurodollar Tranches shall be outstanding at any one time.

     Section 2.10. Interest Rates and Payment Dates. (a) Each Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to the Eurodollar Rate determined for such day plus the Applicable Margin.

     (b) Each ABR Loan shall bear interest at a rate per annum equal to the ABR plus the Applicable Margin.

     (c) (i) If any amount of principal of any Loan or LC Reimbursement Obligation is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Requirements of Law.

          (ii) If any amount (other than principal of any Loan or LC Reimbursement Obligation) payable by the Borrower under any Loan Document is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, then upon the request of the Required Lenders such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Requirements of Law.

          (iii) Upon the request of the Required Lenders, while any Event of Default exists, the Borrower shall pay interest on the principal amount of all outstanding Obligations hereunder at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Requirements of Law.

          (iv) Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand.

     (d) Interest on each Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any bankruptcy, insolvency, reorganization or similar law.

     Section 2.11. Computation of Interest and Fees. (a) Interest and fees payable pursuant hereto shall be calculated on the basis of a 360-day year for the actual days elapsed, except that, with respect to ABR Loans the rate of interest on which is calculated on the basis of the Prime Rate, the interest thereon shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed. The Administrative Agent shall as soon as practicable notify the Borrower and the Lenders of each determination of a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a change in the ABR or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Borrower and the Lenders of the effective date and the amount of each such change in interest rate.

     (b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error.

     Section 2.12. Inability to Determine Interest Rate. If prior to the first day of any Interest Period:

     (b) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or

     (b) the Administrative Agent shall have received notice from the Required Lenders that the Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Loans during such Interest Period,

the Administrative Agent shall give facsimile or telephonic notice thereof to the Borrower and the relevant Lenders as soon as practicable thereafter. If such notice is given (i) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as ABR Loans, (ii) any Loans that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as ABR Loans and (iii) any outstanding Eurodollar Loans shall be converted, on the last day of the then-current Interest Period, to ABR Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans shall be made or continued as such, nor shall the Borrower have the right to convert Loans to Eurodollar Loans.

     Section 2.13. Pro Rata Treatment and Payments. (a) Each borrowing by the Borrower from the Lenders hereunder, each payment by the Borrower on account of any commitment fee and any reduction of the Commitments of the Lenders shall be made pro rata according to the Applicable Percentages of the Lenders.

     (b) Each payment (including each prepayment) by the Borrower on account of principal of and interest on the Loans shall be made pro rata according to the Applicable Percentages, as the case may be, of the Lenders.

     (c) All payments (including prepayments) to be made by the Borrower hereunder, whether on account of principal, interest, fees or otherwise, shall be made without any condition or deduction for any counterclaim, defense, recoupment or setoff and shall be made prior to 12:00 Noon, Cleveland, Ohio time, on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Funding Office, in Dollars and in immediately available funds. The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal pursuant to the preceding two sentences, interest thereon shall be payable at the then applicable rate during such extension.

     (d) 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 2.03, 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 such amount 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 a payment to be made by 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 and (ii) in the case of a payment to be made by the Borrower, the interest rate applicable to ABR Loans. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

     (e) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or the Issuing Bank, with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. Nothing herein shall be deemed to limit the rights of the Administrative Agent, the Issuing Bank or any Lender against the Borrower.

     (f) Whenever any payment received by the Administrative Agent under this Agreement or any of the other Loan Documents is insufficient to pay in full all amounts due and payable to the Administrative Agent, the Lenders, and the Issuing Bank under or in respect of this Agreement and the other Loan Documents on any date, the Administrative Agent may, but shall not be obligated to, distribute such payment in the order of priority set forth in Section 8.03. If the Administrative Agent receives funds for application to the Obligations of the Loan Parties under

or in respect of the Loan Documents under circumstances for which the Loan Documents do not specify the manner in which such funds are to be applied, the Administrative Agent may, but shall not be obligated to, distribute such funds in the order of priority set forth in Section 8.03.

     (g) The Borrower hereby authorizes each Lender and each of its Affiliates, if and to the extent any payment owed to such Lender is not made when due hereunder or any other Loan Document, to charge from time to time, to the fullest extent permitted by applicable law, against any or all of the Borrower’s accounts with such Lender or such Affiliate any amount so due.

     (h) The obligations of the Lenders hereunder to make Loans to fund participations in Letters of Credit and to make payments pursuant to Section 10.05(c) are several and not joint. The failure of any Lender to make any Loan, to fund any such participation or to make any payment under Section 10.05(c) on any date required hereunder, shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to make its Loan, to purchase its participation or to make its payment under Section 10.05(c).

     (i) Nothing herein shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain funds for any Loan in any particular place or manner.

     Section 2.14. Illegality. Notwithstanding any other provision herein, if the adoption of or any change in any Requirement of Law or in the interpretation or application thereof shall make it unlawful for any Lender to make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and convert ABR Loans to Eurodollar Loans shall forthwith be cancelled and (b) such Lender’s Loans then outstanding as Eurodollar Loans, if any, shall be converted automatically to ABR Loans on the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by law. If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, the Borrower shall pay to such Lender such amounts, if any, as may be required pursuant to Section 2.17.

     Section 2.15. Increased Costs. (a) If any Change in Law shall:

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

          (ii) subject any Lender or the Issuing Bank to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender or the Issuing Bank in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 2.16 and the imposition of, or any change in the rate of, any Excluded Tax payable by such Lender or the Issuing Bank); or

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

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

     (b) If any Lender or the Issuing Bank determines that any Change in Law affecting such Lender or the Issuing Bank or any lending office of such Lender or such Lender’s or the Issuing Bank’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company for any such reduction suffered.

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

     (d) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs incurred or reductions suffered more than nine (9) months prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof).

     (e) The obligations of the Borrower pursuant to this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

     Section 2.16. Taxes.

     (a) Any and all payments by or on account of any obligation of the Borrower or Holdings hereunder or under any other Loan Document shall be made free and clear of and without reduction or withholding for any Indemnified Taxes or Other Taxes, provided that if the Borrower or Holdings shall be required by applicable law to deduct any Indemnified Taxes (including any 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) the Administrative Agent, Lender or Issuing Bank, 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 Holdings, as the case may be, shall make such deductions and (iii) the Borrower or Holdings, as the case may be, shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

     (b) Without limiting the provisions of paragraph (a) above, the Borrower and Holdings shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

     (c) The Borrower and Holdings shall, jointly and severally, indemnify the Administrative Agent, each Lender and the Issuing Bank, within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, 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 as to the amount of such payment or liability delivered to the Borrower or Holdings, as applicable, by a Lender or the Issuing Bank (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error.

     (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower or Holdings, as the case may be to a Governmental Authority, the Borrower or Holdings, as the case may be, 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) 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 or Holdings, as the case may be, is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Loan Document shall deliver to the Borrower and Holdings (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, Holdings or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if requested by the Borrower, Holdings or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower, Holdings or the Administrative Agent as will enable the Borrower, Holdings or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

     (f) The agreements in this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

     Section 2.17. Indemnity. The Borrower agrees to indemnify each Lender and to hold each Lender harmless from any loss or expense that such Lender may sustain or incur as a consequence of (a) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (b) default by the Borrower in making any prepayment of or conversion from Eurodollar Loans after the Borrower has given a notice thereof in accordance with the provisions of this Agreement, (c) the making of a prepayment of Eurodollar Loans on a day that is not the last day of an Interest Period with respect thereto, or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.20. Such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest that would have accrued on the amount so prepaid, or not so borrowed, converted or continued, for the period from the date of such prepayment or of such failure to borrow, convert or continue to the last day of such Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Loans provided for herein (excluding, however, the Applicable Margin included therein, if any) over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurodollar market. A certificate as to any amounts payable pursuant to this Section submitted to the Borrower by any Lender shall be conclusive in the absence of manifest error. The Borrower shall pay such Lender the amount shown as due on any such Certificate within ten (10) days after receipt thereof. This covenant shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

     Section 2.18. Use of Proceeds. The proceeds of the Loans shall be available (and the Borrower agrees that it will use such proceeds and Letters of Credit) solely (a) to repay the Existing Obligations and (b) for general corporate purposes of the Borrower and the Restricted Subsidiaries in the ordinary course of business, including the exploration, acquisition and development of Oil and Gas Properties. Letters of Credit will be issued only to support general corporate purposes of the Borrower and the Restricted Subsidiaries in the ordinary course of business.

     Section 2.19. Evidence of Debt. (a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing indebtedness of the Borrower to such Lender resulting from each Loan of such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement.

     (b) The Administrative Agent shall maintain the Register pursuant to Section 10.06(c), and a subaccount therein for each Lender, in which shall be recorded (i) the amount of each Loan, made hereunder, the Type thereof and each Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable

or to become due and payable to the Lenders hereunder, (iii) the amount of each Lender’s participation in outstanding Letters of Credit and (iv) both the amount of any sum received by the Administrative Agent hereunder from the Borrower and each Lender’s share thereof.

     (c) The entries made in the Register and the accounts of each Lender maintained pursuant hereto shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded, provided, however, that the failure of any Lender or the Administrative Agent to maintain the Register or any such account, or any error therein, shall not in any manner affect the obligation of the Borrower to repay (with applicable interest) the Loans made to the Borrower in accordance with the terms of this Agreement.

     (d) The Borrower agrees that, upon the request to the Administrative Agent by any applicable Lender, the Borrower will execute and deliver to such Lender, as appropriate, a promissory note of the Borrower evidencing the Loans of such Lender, substantially in the form of Exhibit D with appropriate insertions as to date and principal amount (a “Note”). Each Lender is hereby authorized to record the Borrowing Date, the amount of each relevant Loan and the date and amount of each payment or prepayment of principal thereof, on the schedule annexed to and constituting a part of the Note evidencing such Loan and any such recordation shall constitute prima facie evidence of the accuracy of the information so recorded, provided that the failure by a Lender to make any such recordation (or any error therein) shall not affect any of the obligations of the Borrower under such Note or this Agreement.

     Section 2.20. Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under Section 2.15, or requires the Borrower to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.16, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.15 or 2.16, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

     (b) If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.16, or if any Lender is a Defaulting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 10.06), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that:

          (i) the Borrower shall have paid to the Administrative Agent the assignment fee specified in Section 10.06;

          (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Reimbursement Obligations, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 2.16) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

          (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.16, such assignment will result in a reduction in such compensation or payments thereafter; and

          (iv) such assignment does not conflict with applicable Requirements of Law.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

ARTICLE III

LETTERS OF CREDIT

     Section 3.01. LC Commitment. (a) Subject to the terms and conditions hereof, the Issuing Bank, in reliance on the agreements of the other Lenders set forth in Section 3.04(a), agrees to issue letters of credit (“Letters of Credit”) for the account of the Borrower on any Business Day during the Commitment Period in such form as may be approved from time to time by the Issuing Bank; provided that the Issuing Bank shall have no obligation to issue any Letter of Credit if, after giving effect to such issuance, (i) the LC Obligations would exceed the LC Commitment, (ii) the Aggregate Outstanding Credit would exceed the Borrowing Base, or (iii) the aggregate amount of the Available Commitments would be less than zero. The Existing Letter of Credit shall constitute and be treated as a Letter of Credit issued pursuant to this Agreement.

     (b) Each Letter of Credit shall (i) be denominated in Dollars, (ii) have a face amount of at least $250,000 (unless otherwise agreed by the Issuing Bank), and (iii) expire no later than the earlier of (x) the first anniversary of its date of issuance and (y) the date that is one (1) year after the Termination Date, provided that any Letter of Credit with a one-year term may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in clause (y) above); provided, further, that any Letter of Credit that expires after the Termination Date shall be Cash Collateralized at all times.

     (c) Letters of Credit may be either standby letters of credit or commercial letters of credit.

     (d) Each Letter of Credit shall be subject to ISP98 or the Uniform Customs and, to the extent not inconsistent therewith, the laws of the State of Ohio.

     (e) The Issuing Bank shall not at any time be obligated to issue any Letter of Credit if:

          (i) the issuance of such Letter of Credit would conflict with, or cause the Issuing Bank or any LC Participant to exceed any limits imposed by, any applicable Requirement of Law;

          (ii) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain the Issuing Bank from issuing such Letter of Credit, or any Requirement of Law applicable to the Issuing Bank or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over the Issuing Bank shall prohibit or request that the Issuing Bank refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon the Issuing Bank with respect to such Letter of Credit any restriction, reserve or capital requirement (for which the Issuing Bank is not otherwise compensated hereunder) not in effect on the Closing Date, or shall impose upon the Issuing Bank any unreimbursed loss, cost or expense which was not applicable on the Closing Date and which the Issuing Bank in good faith deems material to it;

          (iii) the issuance of such Letter of Credit would violate one or more policies of the Issuing Bank; or

          (iv) any Lender is at such time a Defaulting Lender hereunder, unless the Issuing Bank has entered into satisfactory arrangements with the Borrower or such Lender to eliminate the Issuing Bank’s risk with respect to such Lender.

     (f) The Issuing Bank shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the documents associated therewith, and the Issuing Bank shall have all of the benefits and immunities (i) provided to the Administrative Agent in Article IX or Section 10.05(c) with respect to any acts taken or omissions suffered by the Issuing Bank in connection with Letters of Credit issued by it or proposed to be issued by it and the documents associated therewith as fully as if the term “Administrative Agent” or “Agent” as used in Article IX or

Section 10.05(c) included the Issuing Bank with respect to such acts or omissions, and (ii) as additionally provided herein with respect to the Issuing Bank.

     (g) References herein to “issue” and derivations thereof with respect to Letters of Credit shall also include extensions or modifications of any outstanding Letters of Credit, unless the content otherwise requires.

     Section 3.02. Procedure for Issuance of Letter of Credit. The Borrower may from time to time request that the Issuing Bank issue a Letter of Credit by delivering to the Issuing Bank at its address for notices specified herein an Application therefor, completed to the satisfaction of the Issuing Bank, and such other certificates, documents and other papers and information as the Issuing Bank may request. Upon receipt of any Application, the Issuing Bank will process such Application and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall promptly issue the Letter of Credit requested thereby (but in no event shall the Issuing Bank be required to issue any Letter of Credit earlier than three Business Days after its receipt of the Application therefor and all such other certificates, documents and other papers and information relating thereto) by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed to by the Issuing Bank and the Borrower. The Issuing Bank shall furnish a copy of such Letter of Credit to the Borrower promptly following the issuance thereof. The Issuing Bank shall promptly furnish to the Administrative Agent, which shall in turn promptly furnish to the Lenders, notice of the issuance of each Letter of Credit (including the amount thereof).

     Section 3.03. Letter of Credit Fees, Commissions and Other Charges. (a) The Borrower will pay a fee on all outstanding Letters of Credit at a per annum rate equal to the Applicable Margin then in effect with respect to Eurodollar Loans, shared ratably among the Lenders and payable quarterly in arrears on each LC Fee Payment Date after the issuance date. In addition, the Borrower shall pay to the Issuing Bank for its own account a fronting fee of 0.125% per annum on the stated face of each Letter of Credit, payable quarterly in arrears on each LC Fee Payment Date after the issuance date.

     (b) In addition to the foregoing fees, the Borrower shall pay or reimburse the Issuing Bank for such normal and customary costs and expenses as are incurred or charged by the Issuing Bank in issuing, negotiating, effecting payment under, amending or otherwise administering any Letter of Credit.

     Section 3.04. LC Participations. (a) The Issuing Bank irrevocably agrees to grant and hereby grants to each LC Participant, and, to induce the Issuing Bank to issue Letters of Credit hereunder, each LC Participant irrevocably agrees to accept and purchase and hereby accepts and purchases from the Issuing Bank, on the terms and conditions hereinafter stated, for such LC Participant’s own account and risk an undivided interest equal to such LC Participant’s Applicable Percentage in the Issuing Bank’s obligations and rights under and in respect of each Letter of Credit issued hereunder and the amount of each draft paid by the Issuing Bank thereunder. Each LC Participant unconditionally and irrevocably agrees with the Issuing Bank that, if a draft is paid under any Letter of Credit for which the Issuing Bank is not reimbursed in full by the Borrower in accordance with the terms of this Agreement, such LC Participant shall pay to the Issuing Bank upon demand at the Issuing Bank’s address for notices specified herein an amount equal to such LC Participant’s Applicable Percentage of the amount of such draft, or any part thereof, that is not so reimbursed.

     (b) If any amount required to be paid by any LC Participant to the Issuing Bank pursuant to Section 3.04(a) in respect of any unreimbursed portion of any payment made by the Issuing Bank under any Letter of Credit is paid to the Issuing Bank within three (3) Business Days after the date such payment is due, such LC Participant shall pay to the Issuing Bank on demand an amount equal to the product of (i) such amount, times (ii) the daily average Federal Funds Effective Rate during the period from and including the date such payment is required to the date on which such payment is immediately available to the Issuing Bank, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360. If any such amount required to be paid by any LC Participant pursuant to Section 3.04(a) is not made available to the Issuing Bank by such LC Participant within three (3) Business Days after the date such payment is due, the Issuing Bank shall be entitled to recover from such LC Participant, on demand, such amount with interest thereon calculated from such due date at the rate per annum applicable to ABR Loans. A certificate of the Issuing Bank submitted to any LC Participant with respect to any amounts owing under this Section shall be conclusive in the absence of manifest error.

     (c) Whenever, at any time after the Issuing Bank has made payment under any Letter of Credit and has received from any LC Participant its pro rata share of such payment in accordance with Section 3.04(a), the Issuing Bank receives any payment related to such Letter of Credit (whether directly from the Borrower or otherwise, including proceeds of collateral applied thereto by the Issuing Bank), or any payment of interest on account thereof, the Issuing Bank will distribute to such LC Participant its pro rata share thereof; provided, however, that in the event that any such payment received by the Issuing Bank shall be required to be returned by the Issuing Bank, such LC Participant shall return to the Issuing Bank the portion thereof previously distributed by the Issuing Bank to it.

     (d) Each LC Participant’s obligation to purchase participating interests pursuant to Section 3.04(a) shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any setoff, counterclaim, recoupment, defense or other right that such LC Participant or the Borrower may have against the Issuing Bank, the Borrower or any other Person for any reason whatsoever, (ii) the occurrence or continuance of a Default or an Event of Default or the failure to satisfy any of the other conditions specified in Article IV; (iii) any adverse change in the condition (financial or otherwise) of any Loan Party; (iv) any breach of this Agreement or any other Loan Document by the Borrower, any other Loan Party or any other Lender; or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.

     Section 3.05. Reimbursement Obligation of the Borrower. The Borrower agrees to reimburse the Issuing Bank on the Business Day next succeeding the Business Day on which the Issuing Bank notifies the Borrower of the date and amount of a draft presented under any Letter of Credit and paid by the Issuing Bank for the amount of (a) such draft so paid and (b) any Taxes, fees, charges or other costs or expenses incurred by the Issuing Bank in connection with such payment. Each such payment shall be made to the Issuing Bank at its address for notices specified herein in Dollars and in immediately available funds. Interest shall be payable on any such amounts from the date on which the relevant draft is paid until payment in full at the rate set forth in (i) until the Business Day next succeeding the date of the relevant notice, Section 2.10(b) and (ii) thereafter, the Default Rate.

     Section 3.06. Obligations Absolute. The Borrower’s obligations under this Article III (including its reimbursement obligations under Section 3.05) 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 (a) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (b) 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, (c) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (d) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any 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 the Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination.

     Section 3.07. Letter of Credit Payments. If any draft shall be presented for payment under any Letter of Credit, the Issuing Bank shall promptly notify the Borrower of the date and amount thereof. The responsibility of the Issuing Bank to the Borrower in connection with any draft presented for payment under any Letter of Credit shall, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to

determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are in conformity with such Letter of Credit.

     Section 3.08. Applications. To the extent that any provision of any Application related to any Letter of Credit is inconsistent with the provisions of this Article III, the provisions of this Article III shall apply.

     Section 3.09. Cash Collateral Pledge. If there are any outstanding LC Obligations on the Termination Date, then the Borrower shall immediately Cash Collateralize all such outstanding LC Obligations.

ARTICLE V

REPRESENTATIONS AND WARRANTIES

     To induce the Administrative Agent, the Issuing Bank and the Lenders to enter into this Agreement and to make the Loans and issue or participate in the Letters of Credit, Holdings and the Borrower hereby jointly and severally represent and warrant to the Administrative Agent, the Issuing Bank and each Lender that:

     Section 5.01. Financial Condition. The audited consolidated and consolidating balance sheets of Holdings and its Subsidiaries as at December 31, 2003, December 31, 2004, and December 31, 2005, and the related consolidated and consolidating statements of income and of cash flows for the Fiscal Years ended on such dates, reported on by and accompanied by an unqualified report from Kraft, Berger, Grill, Schwartz, Cohen & March LLP, present fairly on a consolidated and consolidating basis the financial condition of Holdings and its Subsidiaries as at such date, and on a consolidated and consolidating basis the results of their operations and their cash flows for the respective Fiscal Years then ended. The unaudited consolidated and consolidating balance sheets of Holdings and its Subsidiaries as at June 30, 2006, and the related unaudited consolidated and consolidating statements of income and cash flows for the three-month period ended on such date, present fairly the consolidated and consolidating financial condition of Holdings and its Subsidiaries as at such date, and the results of their operations and their consolidated and consolidating cash flows for the three-month period then ended (subject to normal year-end audit adjustments). All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved (except as approved by the aforementioned firm of accountants and disclosed therein). No Group Member has any material Indebtedness or Guarantee Obligations, contingent obligations or liabilities of any kind (including any liabilities for taxes, obligations under farm-in agreements or similar arrangements, obligations under long-term leases and unusual forward or long-term commitments (or unrealized or anticipated losses from any unfavorable commitments), and any obligations in respect of Hedge Agreements and Synthetic Debt) that are not referred to or reflected or provided

for in the most recent financial statements referred to in this paragraph. During the period from December 31, 2005, to and including the date hereof there has been no Disposition by any Group Member of any material part of its business or property.

     Section 5.04. Corporate Power; Authorization; Enforceable Obligations. Each Loan Party has the corporate power and authority, and the legal right, to make, deliver and perform the Loan Documents to which it is a party and, in the case of the Borrower, to obtain extensions of credit hereunder. Each Loan Party has taken all necessary organizational action to authorize the execution, delivery and performance of the Loan Documents to which it is a party and, in the case of the Borrower, to authorize the extensions of credit on the terms and conditions of this Agreement. No consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with the extensions of credit hereunder or with the execution, delivery, performance, validity or enforceability of this Agreement or any of the Loan Documents, except (i) consents, authorizations, filings and notices described in Schedule 5.04, which consents, authorizations, filings and notices have been obtained or made and are in full force and effect and (ii) the filings referred to in Section 5.19. Each Loan Document has been duly executed and delivered on behalf of each Loan Party thereto. This Agreement constitutes, and each other Loan Document upon execution will constitute, a legal, valid and binding obligation of each Loan Party thereto, enforceable against each such Loan Party in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law).

     Section 5.05. No Legal Bar. The execution, delivery and performance of this Agreement and the other Loan Documents, the issuance of Letters of Credit, the borrowings hereunder and the use of the proceeds thereof will not violate, conflict with or create a default under any Requirement of Law or any Contractual Obligation of any Group Member and will not result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any Requirement of Law or any such Contractual Obligation (other than the Liens created by the Security Documents). No Requirement of Law or Contractual Obligation applicable to any Loan Party could reasonably be expected to have a Material Adverse Effect.

     Section 5.06. Litigation. No litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of Holdings or the Borrower, threatened by or against any Group Member or against any of their respective properties or revenues (a) with respect to any of the Loan Documents or any of the transactions contemplated thereby, or (b) that could reasonably be expected to have a Material Adverse Effect.

     Section 5.09. Intellectual Property. Each Group Member owns, or is licensed to use, all Intellectual Property necessary for the conduct of its business as currently conducted. No material claim has been asserted and is pending by any Person challenging or questioning the use of any Intellectual Property or the validity or effectiveness of any Intellectual Property, nor does Holdings or the Borrower know of any valid basis for any such claim. The use of Intellectual Property by each Group Member does not infringe on the rights of any Person in any material respect.

     Section 5.10. Taxes. Each Group Member has filed or caused to be filed all Federal, state and other Tax returns that are required to be filed and has paid all Taxes shown to be due and payable on said returns or on any assessments made against it or any of its Property and all other Taxes, fees or other charges imposed on it or any of its property by any Governmental Authority (other than any the amount or validity of which are currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the relevant Group Member); no Tax Lien has been filed, and, to the knowledge of Holdings and the Borrower, no claim is being asserted, with respect to any such Tax, fee or other charge. The Federal income Tax liabilities of each Group Member have been audited by the Internal Revenue Service and satisfied for all taxable years up to and including the taxable year December 31, 2005. No Group Member is a party to any Tax sharing or Tax allocation agreement.

     Section 5.11. Margin Stock.

If requested by any Lender or the Administrative Agent, the Borrower will furnish to the Administrative Agent and each Lender a statement to the foregoing effect in conformity with the requirements of FR Form G-3 or FR Form U-1, as applicable, referred to in Regulation U.

     Section 5.12. Labor Matters.

No termination of a Single Employer Plan has occurred, and no Lien in favor of the PBGC or a Plan has arisen, during such five-year period. The present value of all accrued benefits under each Single Employer Plan (based on those assumptions used to fund such Plans) did not, as of the last annual valuation date prior to the date on which this representation is made or deemed made, exceed the value of the assets of such Plan allocable to such accrued benefits by more than $500,000 in the aggregate as to all such Plans. Neither Holdings, the Borrower nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan that has resulted or could reasonably be expected to result in a material liability under ERISA, and neither Holdings, the Borrower nor any Commonly Controlled Entity would become subject to any material liability under ERISA if the Borrower or any such Commonly Controlled Entity were to withdraw completely from all Multiemployer Plans as of the valuation date most closely preceding the date on which this representation is made or deemed made. No such Multiemployer Plan is in Reorganization or Insolvent.

     Section 5.14. Investment Company Act; Other Regulations. No Group Member is an “investment company,” or a company “controlled” by an “investment company,” within the meaning of the Investment Company Act of 1940.

     Section 5.17. Accuracy of Information, Etc. No statement or information contained in this Agreement, any other Loan Document, the Confidential Information Memorandum or any other document, report, certificate or statement furnished by or on behalf of any Loan Party to the Administrative Agent or the Lenders, or any of them, in connection with the transactions contemplated by this Agreement or the other Loan Documents, contained as of the date such statement, information, document or certificate was so furnished (or, in the case of the Confidential Information Memorandum, as of the date of this Agreement), any untrue statement of a material fact or omitted to state a material fact necessary to make the statements contained herein or therein not misleading. The projections and pro forma financial information contained in the materials referenced above are based upon good faith estimates and assumptions believed by management of the Borrower to be reasonable at the time made, it being recognized by the Lenders that such financial information as it relates to future events is not to be viewed as fact and that actual results during the period or periods covered by such financial information may differ from the projected results set forth therein by a material amount. There is no fact known to any Loan Party that could reasonably be expected to have a Material Adverse Effect that has not been expressly disclosed herein, in the other Loan Documents, in the Confidential Information Memorandum or in any other documents, certificates and statements furnished to the

Administrative Agent and the Lenders for use in connection with the transactions contemplated hereby and by the other Loan Documents. There are no statements or conclusions in any Engineering Report delivered to the Administrative Agent which are based upon or include misleading information or fail to take into account material information regarding the matters reported therein (it being understood that projections concerning volumes attributable to Oil and Gas Properties and production and cost estimates contained in each Engineering Report are necessarily based upon professional opinions, estimates and projections and that Holdings, the Borrower and its Restricted Subsidiaries do not warrant that such opinions, estimates and projections will ultimately prove to have been accurate).

     Section 5.18. Oil and Gas Properties. (a) The Borrower and each of its Restricted Subsidiaries has good and defensible title to, or a valid leasehold interest in, all of its respective Oil and Gas Properties, and none of such Oil and Gas Properties is subject to any Lien except for Permitted Liens. All such Oil and Gas Properties are valid, subsisting, and in full force and effect, and all rentals, royalties and other amounts due and payable in respect thereof have been duly paid. After giving full effect to Permitted Liens, the Borrower or the Restricted Subsidiary specified as the owner of any such Oil and Gas Properties owns the net interests in production attributable to the Oil and Gas Properties as reflected in the most recently delivered Engineering Report, and the ownership of such Oil and Gas Properties does not in any material respect obligate the Borrower or such Restricted Subsidiary to bear the costs and expenses relating to the maintenance, development and operations of each such Oil and Gas Property in an amount in excess of the working interest of such Oil and Gas Property set forth in the most recently delivered Engineering Report that is not offset by a corresponding proportionate increase in the Borrower’s or such Restricted Subsidiary’s net revenue interest in such Oil and Gas Property.

     (b) All Oil and Gas Properties of the Borrower and its Restricted Subsidiaries (and all properties unitized therewith) have been and are being maintained, operated and developed in a good and workmanlike manner, in accordance with prudent industry standards, in conformity with all applicable Requirements of Law and in conformity with the provisions of all leases, subleases and other contracts comprising any part of the Oil and Gas Properties of the Borrower and its Restricted Subsidiaries and in conformity with any existing Permitted Liens. None of the Oil and Gas Properties of the Borrower or any of its Restricted Subsidiaries 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). None of the wells comprising any part of the Oil and Gas Properties of the Borrower and its Restricted Subsidiaries (or properties unitized therewith) are deviated from the vertical more than the maximum permitted by applicable Requirements of Law, and such wells are bottomed under and are producing from, and the well bores are wholly within, such Oil and Gas Properties (or in the case of wells located on properties unitized therewith, such unitized properties) of the Borrower or any such Restricted Subsidiary. All or substantially all of the wells comprising part of the Oil and Gas Properties of the Borrower and its Restricted Subsidiaries are currently in production, except for temporary shut-ins. Each well drilled in respect of Proved Developed Producing Reserves of the Borrower and its Restricted Subsidiaries described in the Initial Engineering Report and each subsequent Engineering Report delivered to the Administrative Agent (i) is capable of, and is presently, either producing Hydrocarbons in commercially profitable quantities or in the process of being worked over or enhanced, and the Borrower or the Restricted Subsidiary that owns such Proved Developed Producing Reserves is currently receiving payments for its share of production, with no funds in respect of any thereof being presently held in suspense pending delivery of appropriate division orders, and (ii) has been drilled, bottomed, completed, and operated in compliance with all applicable Requirements of Law. The Borrower and each Restricted Subsidiary has obtained all governmental approvals, consents, licenses and permits and all easements, rights-of-way and other fee and leasehold interests necessary to own, drill, develop and operate its Oil and Gas Properties, all of which are in full force and effect and neither the Borrower nor any of its Restricted Subsidiaries has received notice from any Governmental Authority or other Person of any violations in respect of any such licenses or permits.

     (c) All pipelines, wells, gas processing plants, platforms and other material improvements, fixtures and equipment owned in whole or in part by the Borrower or any of its Restricted 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 Restricted Subsidiaries, in a manner consistent with the Borrower’s or such Restricted Subsidiary’s past practices. All material Leases, deeds, and other agreements forming any part of the Oil and Gas Properties of the Borrower and its Restricted Subsidiaries to which Proved Reserves are attributed in the Initial Engineering Report and each subsequent Engineering Report delivered

to the Administrative Agent are valid and subsisting and in full force and effect. All rents, royalties and other payments due and payable under such Leases, deeds, and other agreements have been properly and timely paid other than to the extent such could not reasonably be expected to cause the loss or forfeiture of any such Proved Reserves. None of the Borrower nor any of its Restricted Subsidiaries (i) is in default with respect to any of its obligations (and no such Loan Party is aware of any default by any third party with respect to such third party’s obligations) under any such Leases, deeds, and other agreements, or under any Permitted Liens, or otherwise attendant to the ownership or operation of any part of the Oil and Gas Properties of the Borrower and its Restricted Subsidiaries, where such default could materially adversely affect the ownership or operation of any such Oil and Gas Properties to which any Proved Reserves are attributable. None of the Borrower nor any of its Restricted Subsidiaries (i) is currently accounting for any royalties, or overriding royalties or other payments out of production, on a basis (other than delivery in kind) less favorable to such Loan Party than proceeds received by such Loan Party (calculated at the well) from sale of production, or (ii) has any liability (or alleged liability) to account for the same on any such less favorable basis.

     (d) The Oil and Gas Properties of the Borrower and its Subsidiaries that are included in the Initial Borrowing Base are listed on Schedule 5.18(d).

     Section 5.19. Security Documents. (a) The Guarantee and Collateral Agreement is effective to create in favor of the Administrative Agent, for the benefit of the Secured Parties, a legal, valid and enforceable security interest in the Collateral described therein and proceeds thereof. In the case of the Pledged Equity Interests described in the Guarantee and Collateral Agreement, when stock certificates representing such Pledged Equity Interests are delivered to the Administrative Agent, and in the case of the other Collateral described in the Guarantee and Collateral Agreement, when financing statements and other filings specified on Schedule 5.19(a) in appropriate form are filed in the offices specified on Schedule 5.19(a), the Guarantee and Collateral Agreement shall constitute a fully perfected Lien on, and security interest in, all right, title and interest of the Loan Parties in such Collateral and the proceeds thereof, as security for the Obligations, in each case prior and superior in right to any other Person (except, in the case of Collateral other than Pledged Equity Interests, Permitted Liens).

     (b) Upon the execution and delivery thereof, each of the Mortgages will create in favor of the Administrative Agent, for the benefit of the Secured Parties, a legal, valid and enforceable Lien on the Mortgaged Properties described therein and proceeds thereof, and when the Mortgages are filed in the offices specified on Schedule 5.19(b), each such Mortgage shall constitute a fully perfected Lien on, and security interest in, all right, title and interest of the Borrower and its Restricted Subsidiaries in the Mortgaged Properties and the proceeds thereof, as security for the Obligations (as defined in the relevant Mortgage), in each case prior and superior in right to any other Person (except Permitted Liens).

     (c) The Holdings Pledge Agreement is effective to create in favor of the Administrative Agent, for the benefit of the Secured Parties, a legal, valid and enforceable security interest in the Pledged Stock and the other Collateral (as defined in the Pledge Agreement). In the case of the Pledged Stock, when stock certificates representing such Pledged Stock are delivered to the Administrative Agent, and in the case of the other Collateral described in the Pledge Agreement, when financing statements and other filings specified on Schedule 5.19(c) in appropriate form are filed in the offices specified on Schedule 5.19(c), the Pledge Agreement shall constitute a fully perfected Lien on, and security interest in, all right, title and interest of Holdings in and to the Pledged Stock and the other Collateral, as security for the Obligations, in each case, prior and superior in right to any other Person.

     Section 5.20. Solvency. Each Loan Party is, and after giving effect to the incurrence of all Indebtedness and obligations being incurred in connection herewith will be and will continue to be, Solvent.

     Section 5.21. Certain Documents. The Borrower has delivered to the Administrative Agent complete and correct executed copies of each of the NGAS Securities Purchase Documents, including any amendments, supplements or modifications with respect to any of the foregoing. The NGAS Warrants have expired in accordance with their terms.

     Section 5.22. Material Contracts. Schedule 5.22 sets forth as of the Closing Date a complete and accurate list of all Material Contracts of the Borrower and its Restricted Subsidiaries, showing the parties, subject matter and term thereof. Each such Material Contract has been duly authorized, executed and delivered by all of the

parties thereto, has not been amended, supplemented or otherwise modified, is in full force and effect and is binding upon and enforceable against all parties thereto in accordance with its terms, and there exists no default or termination event under any Material Contract by any party thereto.

     Section 5.23. Insurance. Schedule 5.23 sets forth as of the Closing Date a complete and accurate list of all policies of insurance maintained by the Borrower and its Restricted Subsidiaries, showing with respect to each such policy the type of insurance, the coverage amount, the carrier, and the duration of coverage. All premiums with respect to such policies of insurance have been fully paid.

     Section 5.24. Marketing Arrangements. Except as set forth in Schedule 5.24, no Oil and Gas Property of the Borrower or any Restricted Subsidiary is subject to any contractual or other arrangement (i) whereby payment for production is or can be deferred for a substantial period after the month in which such production is delivered (in the case of oil, not in excess of sixty (60) days, and in the case of gas, not in excess of ninety (90) days) or (ii) whereby payments are made to any such Loan Party other than by check, draft, wire transfer or other similar writings, instruments or communications for the immediate payment of money. Except for production sales contracts, processing agreements, transportation agreements and other agreements relating to the marketing of production that are listed in Schedule 5.24 in connection with the Oil and Gas Properties of the Borrower and its Restricted Subsidiaries to which such contract or agreement relates: (i) no Oil and Gas Property of any such Loan Party is subject to any contractual or other arrangement for the sale, processing or transportation of production (or otherwise related to the marketing of production) which cannot be canceled on less than one hundred twenty (120) days’ notice and (ii) all contractual or other arrangements for the sale, processing or transportation of production (or otherwise related to the marketing of production) are bona fide arm’s length transactions made on the best terms reasonably available with third parties not affiliated with the Loan Parties. The Borrower and each Restricted Subsidiary is presently receiving a price for all production from (or attributable to) each of its respective Oil and Gas Properties covered by a production sales contract or marketing contract listed in Schedule 5.24 that is computed in accordance with the terms of such contract, and no Loan Party is having deliveries of production from such Oil and Gas Property curtailed by any purchaser or transporter of production substantially below such property’s delivery capacity, except for curtailments caused (a) by an act or event of force majeure not reasonably within the control of and not caused by the fault or negligence of any Loan Party and which by the exercise of reasonable diligence such Loan Party is unable to prevent or overcome, and (b) by routine maintenance requirements in the ordinary course of business.

     Section 5.25. Right to Receive Payment for Future Production. Except as set forth in Schedule 5.25, neither the Borrower nor any Restricted Subsidiary, nor any of their respective predecessors in title, has received or is obligated in any material respect by virtue of any prepayments (including payments for gas not taken pursuant to “take or pay” or other similar arrangements) for any Hydrocarbons produced or to be produced from any Oil and Gas Properties of the Borrower or any Restricted Subsidiary after the date hereof. Except as set forth in Schedule 5.25, no Oil and Gas Property of the Borrower or any Restricted Subsidiary is subject to any “take or pay,” gas imbalances or other similar arrangement (i) which can be satisfied in whole or in part by the production or transportation of gas from other properties or (ii) as a result of which production from any such Oil and Gas Property may be required to be delivered to one or more third parties without payment (or without full payment) therefor as a result of payments made, or other actions taken, with respect to other properties. Except as set forth in Schedule 5.25, there is no Oil and Gas Property of the Borrower or any Restricted Subsidiary with respect to which the Borrower or any Restricted Subsidiary, or any of their respective predecessors in title, has, prior to the date hereof, taken more (overproduced), or less (“underproduced”), gas from the lands covered thereby (or pooled or unitized therewith) than its ownership interest in such Oil and Gas Property would entitle it to take; and Schedule 5.25 accurately reflects, for each well or unit with respect to which such an imbalance is shown thereon to exist, (i) whether the Borrower, any such Restricted Subsidiary or any such Oil and Gas Property is overproduced or underproduced and (ii) the volumes (in cubic feet or British thermal units) of such overproduction or underproduction and the effective date of such information. No Oil and Gas Property of the Borrower or any Restricted Subsidiary is subject at the present time to any regulatory refund obligation and, to the best of the Borrower’s knowledge, no facts exist which might cause the same to be imposed.

     Section 5.26. Foreign Assets Control Regulations, Etc.

     (a) Neither the making of the Loans to the Borrower hereunder nor its use of the proceeds thereof will violate the Trading with the Enemy Act, as amended, or any of the foreign assets control regulations of the United States Treasury Department (31 CFR, subtitle B, Chapter V, as amended) or any enabling legislation or executive order relating thereto.

     (b) No Group Member (i) is a Person described or designated in the Specially Designated Nationals and Blocked Persons List of the Office of Foreign Assets Control or in Section 1 of the Anti-Terrorism Order or (ii) engages in any dealings or transactions with any such Person. Each Group Member is in compliance, in all material respects, with the USA Patriot Act.

     (c) No part of the proceeds from the Loans will be used, directly or indirectly, for any payments to any governmental official or employee, political party, official of a political party, candidate for political office, or anyone else acting in an official capacity, in order to obtain, retain or direct business or obtain any improper advantage, in violation of the United States Foreign Corrupt Practices Act of 1977, as amended, assuming in all cases that such Act applies to the Borrower.

     Section 7.18. Gas Imbalances, Take-or-Pay or other Prepayments. Purchase, assume, enter into or permit to exist any contracts, agreements or other arrangements which allow gas imbalances, take-or-pay or other prepayments with respect to the Oil and Gas Properties of the Borrower or any Restricted Subsidiary which would require the Borrower or any such Restricted Subsidiary to deliver Hydrocarbons from such Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor.

ARTICLE IX

AGENCY

     Section 9.01. Appointment and Authority. Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents 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 or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Administrative Agent, the Lenders and the Issuing Bank, and neither the Borrower nor any other Group Member shall have rights as a third party beneficiary of any of such provisions.

     Section 9.02. Rights as a Lender. The Person serving as the Administrative 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 the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with any Group Member or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

     Section 9.03. Exculpatory Provisions. The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, the Administrative Agent:

     (a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;

     (b) shall not have any 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 as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable law; and

     (c) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.

     The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 10.01 and 8.01) or (ii) in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to the Administrative Agent by the Borrower, a Lender or the Issuing Bank.

     The Administrative Agent 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 thereunder 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 therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

     Section 9.04. Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or the Issuing Bank, the Administrative Agent may presume that such condition is satisfactory to such Lender or the Issuing Bank unless the Administrative Agent shall have received notice to the contrary from such Lender or the Issuing Bank prior to the making of such Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

     Section 9.05. Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document 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 of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

     Section 9.06. Resignation of Administrative Agent. The Administrative Agent may at any time give notice of its resignation to the Lenders, the Issuing Bank and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent meeting the qualifications set forth above provided that if the Administrative Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (a) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Lenders or the Issuing Bank under any of the Loan Documents, the retiring Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and (b) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and the Issuing Bank directly, until such time as the Required Lenders appoint a successor Administrative Agent as provided for above in this Section. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this Section). The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article and Section 10.05 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent.

     Any resignation by KeyBank as Administrative Agent pursuant to this Section shall also constitute its resignation as Issuing Bank. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, (i) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Issuing Bank, (ii) the retiring Issuing Bank shall be discharged from all of their respective duties and obligations hereunder or under the other Loan Documents, and (iii) the successor Issuing Bank shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to the retiring Issuing Bank to effectively assume the obligations of the retiring Issuing Bank with respect to such Letters of Credit.

     Section 9.07. Non-Reliance on Administrative Agent and Other Lenders. Each Lender and the Issuing Bank acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender and the Issuing Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties 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 or any related agreement or any document furnished hereunder or thereunder.

     Section 9.08. No Other Duties, etc. Anything herein to the contrary notwithstanding, the Bookrunner and the Arranger listed on the cover page hereof shall not have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent, a Lender or the Issuing Bank hereunder.

     Section 9.09. Administrative Agent May File Proofs of Claim. In case of the pendency of any case, proceeding or other action of a nature or type referred to in Section 8.01(f)(i) or any other judicial proceeding relative to any Loan Party, the Administrative Agent (irrespective of whether the principal of any Loan or LC Obligation 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, LC Obligations and all other Obligations 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, the Issuing Bank and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the Issuing Bank and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the Issuing Bank and the Administrative Agent under Sections 2.04, 3.03, and 10.05) 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 and the Issuing Bank to make such payments to the Administrative Agent and, if the Administrative Agent shall consent to the making of such payments directly to the Lenders and the Issuing Bank, 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 Sections 2.04 and 10.05.

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

     Section 9.10. Collateral and Guarantee Matters. The Lenders and the Issuing Bank irrevocably authorize the Administrative Agent, at its option and in its discretion:

     (a) to release any Lien on any property granted to or held by the Administrative Agent under any Loan Document (i) upon termination of the Commitments and payment in full of all Obligations (other than contingent indemnification obligations and Hedge Bank Obligations) and the expiration or termination of all Letters of Credit, (ii) that is sold or to be sold as part of or in connection with any sale expressly permitted hereunder or under any other Loan Document, or (iii) if approved, authorized or ratified in writing in accordance with Section 10.01;

     (c) to subordinate any Lien on any property granted to or held by the Administrative Agent under any Loan Document to the holder of any Lien on such property that is permitted by Section 7.03(f).

     Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any Guarantor from its guarantee under the Guarantee and Collateral Agreement pursuant to this Section 9.10. In each case as specified in this Section 9.10, the Administrative Agent will, at the Borrower’s expense, execute and deliver to the applicable Loan Party such documents as such Loan Party may reasonably request to evidence the release of such item of Collateral from the Liens granted under the Collateral Documents or to subordinate its interest in such item, or to release such Guarantor from its guarantee under the Guarantee and Collateral Agreement, in each case in accordance with the terms of the Loan Documents and this Section 9.10.

     Section 10.06. Successors and Assigns; Participations and Assignments.

     (a) Successors and Assigns Generally. 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, except that the neither the Borrower nor any other Loan Party may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section, (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section, or (iv) to an SPC (as defined in paragraph (h) below) in accordance with the provisions of paragraph (h) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). 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, Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

     (b) Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment(s), and the Loans (including for purposes of this Section 10.06(b), participations in LC Obligations) at the time owing to it; provided that any such assignment shall be subject to the following conditions:

          (i) Minimum Amounts.

               (A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned;

               (B) in any case not described in paragraph (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans 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 or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000, unless each of the Administrative Agent and, so long as no Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed);

          (ii) Proportionate Amounts. 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 with respect to the Loan or the Commitment assigned;

          (iii) Required Consents. No consent shall be required for any assignment except to the extent required by paragraph (b)(i)(B) of this Section and, in addition:

               (A) the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund;

               (B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments in respect of any Commitment if such assignment is to a Person that is not a Lender, an Affiliate of such Lender or an Approved Fund with respect to such Lender; and

               (C) the consent of the Issuing Bank (such consent not to be unreasonably withheld or delayed) shall be required for any assignment that increases the obligation of the assignee to participate in exposure under one or more Letters of Credit (whether or not then outstanding).

          (iv) Assignment and Assumption. 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; provided, however, that the Administrative Agent may, in its sole discretion, waive such processing and recordation fee in the case of an assignment. The assignee, if it is not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire;

          (v) No Assignment to Borrower. No such assignment shall be made to the Borrower or any of the Borrower’s Affiliates or Subsidiaries;

          (vi) No Assignment to Natural Persons. No such assignment shall be made to a natural person; and

          (vii) Limitation. No such assignment shall be permitted without the prior written consent of the Administrative Agent until the Administrative Agent shall have notified the Lenders that syndication of the Commitments has been completed.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.15, 2.16, 2.17 and 10.05 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section.

     (c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in Cleveland, Ohio, 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 Commitments of, and principal amounts of the Loans and LC Reimbursement Obligations owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. Any assignment of any Loan, whether or not evidenced by a Note, shall be effective only upon appropriate entries with respect thereto being made in the Register (and each Note shall expressly so provide). The Register shall be available for inspection by the Borrower, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

     (d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment(s) and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the 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 or any other Loan Document; 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 clause (i) of Section 10.01 that directly affects such Participant. Subject to paragraph (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Section 2.15 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall

be entitled to the benefits of Section 10.07(b) as though it were a Lender, provided such Participant agrees to be subject to Section 10.07(a) as though it were a Lender.

     (e) Limitations Upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Sections 2.15 and 2.16 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 2.16 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 2.16(e) as though it were a Lender.

     (f) Certain Pledges. 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; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

     (g) Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

     (h) Special Purpose Funding Vehicles. Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower (an “SPC”) the option to provide all or any part of any Loan that such Granting Lender would otherwise be obligated to make pursuant to this Agreement; provided, that (i) nothing herein shall constitute a commitment by any SPC to fund any Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to make all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof or, if it fails to do so, to make such payment to the Administrative Agent as is required by Section 2.13(e). The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees that (i) no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would be liable, (ii) no SPC shall be entitled to the benefits of Sections 2.15 and 2.16 (or any other increased costs protection provision) and (iii) the Granting Lender shall for all purposes, including, without limitation, the approval of any amendment or waiver of any provision of any Loan Document, remain the Lender of record hereunder. The making of a Loan by a SPC hereunder shall constitute utilization of the appropriate Commitment of the Granting Lender to the same extent, and as if, such Loan was made by such Granting Lender. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior Indebtedness of any SPC, it will not institute against, or join any other Person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency, or liquidation proceeding under the laws of the United States or any State thereof. Notwithstanding anything to the contrary contained in this Agreement, any SPC may (i) with notice to, but without prior consent of, the Borrower and the Administrative Agent and without payment of a processing fee therefor, assign all or any portion of its interest in any Loan to the Granting Lender and (ii) disclose on a confidential basis any non-public information relating to its funding of Loans to any rating agency, commercial paper dealer or provider of any surety or guarantee or credit or liquidity enhancement to such SPC. This subsection (h) may not be amended without the prior written consent of each Granting Lender, all or any part of whose Loans are being funded by the SPC at the time of such amendment.

     (i) Resignation as Issuing Bank After Assignment. Notwithstanding anything to the contrary contained herein, if at any time KeyBank assigns all of its Commitments and Loans pursuant to Section 10.06(b), KeyBank may, upon thirty (30) days’ notice to the Borrower and the Lenders, resign as Issuing Bank. In the event of any such resignation as Issuing Bank, the Borrower shall be entitled to appoint from among the Lenders a

successor Issuing Bank hereunder; provided, however, that no failure by the Borrower to appoint any such successor shall affect the resignation of as Issuing Bank, as the case may be. If KeyBank resigns as Issuing Bank, it shall retain all the rights, powers, privileges and duties of the Issuing Bank hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as Issuing Bank and all LC Obligations with respect thereto (including the right to require the Lenders to fund participations pursuant to Section 3.04(b)). Upon the appointment of a successor Issuing Bank, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Issuing Bank, as the case may be, and (b) the successor Issuing Bank shall issue letters of Credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to KeyBank to effectively assume the obligations of KeyBank with respect to such Letters of Credit.

     (j) Notes. The Borrower, upon receipt of written notice from the relevant Lender, agrees to issue a Note to any Lender requiring a Note to facilitate transactions of the type described in paragraph (b) above.

     Section 10.07. Adjustments; Set-Off. (a) Except to the extent that this Agreement expressly provides for payments to be allocated to a particular Lender or Lenders, if any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans, LC Reimbursement Obligations or other obligations hereunder resulting in such Lender’s receiving payment of a proportion of the aggregate amount of its Loans and LC Reimbursement Obligations and accrued interest thereon or other such obligations greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans, LC Reimbursement Obligations and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, 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, LC Reimbursement Obligations and other amounts owing them, provided that:

          (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and

          (ii) the provisions of this paragraph shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Reimbursement Obligations to any assignee or participant, other than to Holdings, the Borrower or any Subsidiary thereof (as to which the provisions of this paragraph shall apply).

     Each of the Borrower and Holdings 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 Holdings or the Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of Holdings or the Borrower in the amount of such participation.

     (b) If an Event of Default shall have occurred and be continuing, each Lender, the Issuing Bank, and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender, the Issuing Bank or any such Affiliate to or for the credit or the account of Holdings or the Borrower against any and all of the obligations of Holdings or the Borrower now or hereafter existing under this Agreement or any other Loan Document to such Lender or the Issuing Bank, irrespective of whether or not such Lender or the Issuing Bank shall have made any demand under this Agreement or any other Loan Document and although such obligations of Holdings or the Borrower may be contingent or unmatured or are owed to a branch or office of such Lender or the Issuing Bank different from the branch or office holding such deposit or obligated on such indebtedness. The rights of each Lender, the Issuing Bank and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender, the Issuing Bank or their respective Affiliates may have. Each Lender and the Issuing Bank agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application.

     Section 10.08. Counterparts; Integration; Effectiveness; Electronic Execution. This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Loan Documents, and any separate letter agreements with respect to fees payable to the Administrative Agent, constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. 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 10.09. Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

     Section 10.10. Governing Law; Jurisdiction, Etc. (a) This Agreement shall be governed by, and construed in accordance with, the law of the State of Ohio.

     (b) Each of Holdings and the Borrower irrevocably and unconditionally submits, for itself and its Property, to the nonexclusive jurisdiction of the courts of the State of Ohio sitting in Cuyahoga County and of the United States District Court for the Northern District of Ohio, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any other Loan Document, or for recognition or enforcement of any judgment, and each of the parties hereto irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such Ohio State court or, to the fullest extent permitted by applicable law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or in any other Loan Document shall affect any right that the Administrative Agent, any Lender or the Issuing Bank may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against Holdings, the Borrower or any other Loan Party or its properties in the courts of any jurisdiction.

     (c) Each of Holdings and the Borrower irrevocably and unconditionally waives, to the fullest extent permitted by applicable law, any objection that it may now or hereafter have to the laying of venue of any action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

     (d) Each party hereto irrevocably consents to service of process in the manner provided for notices in Section 10.02. Nothing in this Agreement will affect the right of any party hereto to serve process in any other manner permitted by applicable law.

     Section 10.11. Acknowledgements. Each of Holdings and the Borrower hereby acknowledges that:

     (a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents;

     (b) neither the Administrative Agent nor any Lender has any fiduciary relationship with or duty to Holdings or the Borrower arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between Administrative Agent and Lenders, on one hand, and Holdings and the Borrower, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

     (c) no joint venture is created hereby or by the other Loan Documents or otherwise exists by virtue of the transactions contemplated hereby among the Lenders or among Holdings, the Borrower and the Lenders.

     Section 10.12. Treatment of Certain Information; Confidentiality. (a) Each of the Administrative Agent, the Lenders and the Issuing Bank agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors and other representatives (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 purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any 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, 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 or derivative transaction relating to the Borrower and its 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 or (ii) becomes available to the Administrative Agent, any Lender, the Issuing Bank or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower.

     For purposes of this Section, “Information” means all information received from the Borrower or any of its Subsidiaries relating to the Borrower or any of its Subsidiaries or any of their respective businesses, other than any such information that is available to the Administrative Agent, any Lender or the Issuing Bank 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 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 10.13. Interest Rate Limitation. (a) It is the intent of the Administrative Agent, the Lenders and the Borrower to conform to and contract in strict compliance with all applicable usury laws from time to time in effect. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the Highest Lawful Rate. If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the Highest Lawful Rate, the excess interest shall be applied to the principal of the Loans and LC Reimbursement Obligations or, if it exceeds such unpaid principal, refunded to the Borrower. In determining whether the interest contracted for, charged, or received by any Agent or any Lender exceeds the Highest Lawful Rate, such Person may, to the extent permitted by applicable law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder. The right to accelerate maturity of the Loans and the other Obligations does not include the right to accelerate any interest which has not otherwise accrued on the date of such acceleration, and the Administrative Agent and the Lenders do not intend to charge or receive any unearned interest in the event of acceleration.

     (b) If at any time the interest rate (the “Stated Rate”) called for under this Agreement or any other Loan Document exceeds or would exceed the Highest Lawful Rate, the rate at which interest shall accrue thereunder shall automatically be limited to the Highest Lawful Rate, and shall remain at the Highest Lawful Rate until the total amount of interest accrued equals the total amount of interest which would have accrued but for the operation of this sentence. Thereafter, interest shall accrue at the Stated Rate unless and until the Stated Rate would again exceed the Highest Lawful Rate, in which case the immediately preceding sentence shall apply.

     Section 10.14. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

     Section 10.16. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY).

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

Each of the Borrower and Holdings hereby waives and releases, to the fullest extent permitted by law, any claims that it may have against the Administrative Agent and the Arranger with respect to any breach or alleged breach of agency or fiduciary duty.
