(a) If on any date Holdings, the Borrower or any of its Subsidiaries shall receive Net Cash Proceeds from any Asset Sale or Disposition permitted by Section 7.5(e), such Net Cash Proceeds promptly (but in any event no later than 2 Business Days after such receipt) shall be paid by the Borrower to the Administrative Agent, for the ratable benefit of the Lenders, to prepay the Obligations in cash at 100% of the principal amount of the Term Loans so prepaid, plus the sum of (x) accrued and unpaid interest to the repayment date, plus (y) a pro rata portion of the Make-Whole Amount, plus (z) a pro rata portion (based on the amount of the Term Loans prepaid) of the deferred set-up fee referred to in Section 2.9(b)(ii). (b) On any date Parent, Holdings or the Borrower receives proceeds from a Company Sale, (i) all such proceeds (whether or not sufficient to make the following payments in full) shall be immediately applied to repay the Obligations in full in cash and to pay to the Administrative 23 Agent, for the pro rata benefit of the Lenders, the sum of 100% of the principal amount of the Term Loans, plus (x) accrued and unpaid interest to the repayment date, plus (y) the Make-Whole Amount, plus (z) the deferred set-up fee referred to in Section 2.9(b)(i); provided that at the time of any such Company Sale, all of the foregoing Obligations shall be paid in full regardless of the amount of proceeds actually received by Parent, Holdings or the Borrower. (c) Unless the Borrower shall otherwise have repaid in full all Obligations under this Agreement, upon (i) 75 days following a Parent Liquidity Event or (ii) an acceleration of the Obligations pursuant to Section 8, the Borrower shall repay the Obligations in full in cash and pay to the Administrative Agent, for the pro rata benefit of the Lenders, the sum of 100% of the principal amount of the outstanding Term Loans, plus (x) accrued and unpaid interest to the repayment date, plus (y) the Make-Whole Amount, plus (z) the deferred set-up fee referred to in Section 2.9(b)(ii). (d) Subject to Section 2.18, amounts to be applied in connection with a repayment made pursuant to Section 2.12(b) or (c), if the Obligations are not paid in full in cash, shall be applied, first, to accrued and unpaid interest on the Term Loans, second, to the deferred set-up fee referred to in Section 2.9(b), third, to outstanding principal of the Terms Loans (including, without limitation, any capitalized interest that has been added to the principal of the Term Loans) and, fourth, to any remaining Obligations outstanding. The application of any repayment pursuant to this Section 2.12 shall be made, first, to Base Rate Loans, if any, and, second, to Eurodollar Loan. 2.13 [Intentionally Omitted]. 2.14 [Intentionally Omitted]. 2.15 Interest Rates and Payment Dates. (a) Each Eurodollar Loan shall bear interest during each Interest Period with respect thereto at a rate per annum equal to the sum of (i) the Eurodollar Rate determined for such day plus (ii) 4.00% per annum. (b) Each Base Rate Loan shall bear interest at a rate per annum equal to the sum of (i) the Base Rate plus (ii) 3.00% per annum. (c) Each Term Loan also shall accrue additional interest at a rate of 14% per annum. (d)(i) If all or a portion of the principal amount of any Term Loan shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), all outstanding Term Loans (whether or not overdue) shall bear interest at a rate per annum that is equal to the rate that would otherwise be applicable thereto pursuant to the foregoing provisions of this Section plus 2.0%, and (ii) if all or a portion of any interest payable on any Term Loan or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum equal to the rate then applicable to Base Rate Loans plus 2.0%, in each case, with respect to clauses (i) and (ii) above, from the date of such non-payment until such amount is paid in full (after as well as before judgment). 24 (e)(i) Interest accruing pursuant to paragraphs (a) and (b) above shall be payable by the Borrower in cash in arrears on each Interest Payment Date; (ii) interest accruing pursuant to paragraph (c) above shall be calculated on the outstanding principal amount of the Term Loans on a weighted average daily basis and shall be payable by the Borrower in arrears on each Interest Payment Date by increasing the outstanding principal amount of the Term Loans by the amount of such interest due on a pro rata basis based on the Lenders' outstanding Term Loans immediately prior to such interest payment and (iii) interest accruing pursuant to paragraph (d) above shall be payable in cash from time to time on demand. (f) Notwithstanding anything to the contrary set forth in this Section 2.15, if a court of competent jurisdiction determines in a final order that the rate of interest payable hereunder exceeds the highest rate of interest permissible under law (the "Maximum Lawful Rate"), then so long as the Maximum Lawful Rate would be so exceeded, the rate of interest payable hereunder shall be equal to the Maximum Lawful Rate; provided, however, that if at any time thereafter the rate of interest payable hereunder is less than the Maximum Lawful Rate, Borrower shall continue to pay interest hereunder at the Maximum Lawful Rate until such time as the total interest received by the Lenders is equal to the total interest which would have been received had the interest rate payable hereunder been (but for the operation of this paragraph) the interest rate payable since the Closing Date as otherwise provided in this Agreement. Thereafter, interest hereunder shall be paid at the rate(s) of interest and in the manner provided in Sections 2.15(a) through (e) above, unless and until the rate of interest again exceeds the Maximum Lawful Rate, and at that time this paragraph shall again apply. In no event shall the total interest received by the Lenders pursuant to the terms hereof exceed the amount which the Lenders could lawfully have received had the interest due hereunder been calculated for the full term hereof at the Maximum Lawful Rate. If the Maximum Lawful Rate is calculated pursuant to this paragraph, such interest shall be calculated at a daily rate equal to the Maximum Lawful Rate divided by the number of days in the year in which such calculation is made. If, notwithstanding the provisions of this Section 2.15(f), a court of competent jurisdiction shall finally determine that the Lenders have received interest hereunder in excess of the Maximum Lawful Rate, the Lenders shall refund any excess to Borrower or as a court of competent jurisdiction may otherwise order. 2.16 Computation of Interest and Fees. (a) Interest, fees and commissions payable on a per annum basis pursuant hereto shall be calculated on the basis of a 360-day year for the actual days elapsed. The Administrative Agent shall as soon as practicable notify the Borrower and the relevant Lenders of each determination of a Eurodollar Rate. Any change in the interest rate on a Term Loan resulting from a change in the Base Rate 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 relevant 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. The Administrative Agent shall, at the request of the Borrower, 25 deliver to the Borrower a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to Section 2.15(a). 2.17 Inability to Determine Interest Rate. If prior to the first day of any Interest Period: (a) 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 Term Loans during such Interest Period, the Administrative Agent shall give telecopy or telephonic notice thereof to the Borrower and the relevant Lenders as soon as practicable thereafter. If such notice is given (x) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as Base Rate Loans and (y) any outstanding Eurodollar Loans shall be converted, on the last day of the then current Interest Period with respect thereto, to Base Rate Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans shall be continued as such. 2.18 Pro Rata Treatment and Payments. (a) Each borrowing by the Borrower from the Lenders hereunder shall be made pro rata according to the respective Term Loan Percentages of the Lenders. Each payment (other than prepayments) in respect of principal or interest in respect of the Term Loans, and each payment in respect of fees or expenses payable hereunder shall be applied to the amounts of such Obligations owing to the Lenders pro rata according to the respective amounts then due and owing to the Lenders. (b) Each payment (including each prepayment) of the Term Loans outstanding under the Facility shall be allocated among the Lenders holding such Term Loans pro rata based on the principal amount of such Term Loans held by such Lenders. Amounts prepaid on account of the Term Loans may not be reborrowed. (c) [Intentionally Omitted]. (d) [Intentionally Omitted]. (e) All payments (including prepayments) to be made by the Borrower hereunder, whether on account of principal, interest, fees or otherwise, shall be made without setoff or counterclaim and shall be made prior to 12:00 Noon, New York City time, on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Payment 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 26 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. (f) Unless the Administrative Agent shall have been notified in writing by any Lender prior to the Closing Date that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on the Closing Date, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon at a rate equal to the daily average Federal Funds Effective Rate for the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this paragraph shall be conclusive in the absence of manifest error. If such Lender's share of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days of the Closing Date, the Administrative Agent shall also be entitled to recover such amount with interest thereon at the rate per annum applicable to Base Rate Loans on demand, from the Borrower. (g) Unless the Administrative Agent shall have been notified in writing by the Borrower prior to the date of any payment being made hereunder that the Borrower will not make such payment to the Administrative Agent, the Administrative Agent may assume that the Borrower is making such payment, and the Administrative Agent may, but shall not be required to, in reliance upon such assumption, make available to the Lenders their respective pro rata shares of a corresponding amount. If such payment is not made to the Administrative Agent by the Borrower within three Business Days of such required date, the Administrative Agent shall be entitled to recover, on demand, from each Lender to which any amount which was made available pursuant to the preceding sentence, such amount with interest thereon at the rate per annum equal to the daily average Federal Funds Effective Rate. Nothing herein shall be deemed to limit the rights of the Administrative Agent or any Lender against the Borrower. 2.19 Requirements of Law. (a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof: (i) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by Section 2.20 and changes in the rate of tax on the overall net income of such Lender); (ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account 27 of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in the determination of the Eurodollar Rate hereunder; or (iii) shall impose on such Lender any other condition; and the result of any of the foregoing is to increase the cost to such Lender, by an amount which such Lender deems to be material, of making or maintaining Eurodollar Loans, or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Borrower shall promptly pay such Lender, upon such Lender's demand, any additional amounts necessary to compensate such Lender on an after-tax basis for such increased cost or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this Section, it shall promptly notify the Borrower (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled. (b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any Person controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof shall have the effect of reducing the rate of return on such Lender's or such corporation's capital as a consequence of its obligations hereunder to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such Lender's or such corporation's policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrower (with a copy to the Administrative Agent) of a written request therefor, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender on an after-tax basis for such reduction. (c) A certificate as to any additional amounts payable pursuant to this Section submitted by any Lender to the Borrower (with a copy to the Administrative Agent) shall be conclusive in the absence of manifest error. The obligations of the Borrower pursuant to this Section shall survive the termination of this Agreement and the payment of the Obligations in full. 2.20 Taxes. (a) All payments made by the Borrower under this Agreement or any other Loan Document shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding net income taxes and franchise taxes (imposed in lieu of net income taxes) imposed on the Arranger, any Agent or any Lender as a result of a present or former connection between the Arranger, such Agent or such Lender and the jurisdiction of the Governmental Authority imposing such tax or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from the Arranger's, such Agent's or such Lender's having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any other Loan Document). If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings ("Non-Excluded Taxes") are required to be withheld from 28 any amounts payable to the Arranger, any Agent or any Lender hereunder, the amounts so payable to the Arranger, such Agent or such Lender shall be increased to the extent necessary to yield to the Arranger, such Agent or such Lender (after payment of all Non-Excluded Taxes) interest or any such other amounts that would have been received hereunder had such withholding not been required; provided, however, that the Borrower or a Guarantor shall not be required to increase any such amounts payable to the Arranger, any Agent or any Lender with respect to any Non-Excluded Taxes that are attributable to the Arranger's, such Agent's or such Lender's failure to comply with the requirements of paragraph (f) of this Section. The Borrower or the applicable Guarantor shall make any required withholding and pay the full amount withheld to the relevant tax authority or other Governmental Authority in accordance with applicable Requirements of Law. (b) The Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable Requirements of Law. (c) The Borrower shall indemnify the Arranger, each Agent and any Lender for the full amount of Non-Excluded Taxes or Other Taxes arising in connection with payments made under this Agreement (including, without limitation, any Non-Excluded Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.20) paid by the Arranger, such Agent or Lender or any of their respective Affiliates and any liability (including penalties, additions to tax interest and expenses) arising therefrom or with respect thereto. Payment under this indemnification shall be made within ten days from the date the Arranger, any Agent or any Lender or any of their respective Affiliates makes written demand therefor. (d) Whenever any Non-Excluded Taxes or Other Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the Administrative Agent for the account of the Arranger or the relevant Agent or Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. (e) The agreements in this Section 2.20 shall survive the termination of this Agreement and the payment of the Term Loans and all other amounts payable hereunder. (f) Each Lender (or Transferee) that is not a citizen or resident of the United States of America, a corporation, partnership or other entity created or organized in or under the laws of the United States of America (or any jurisdiction thereof), or any estate or trust that is subject to federal income taxation regardless of the source of its income (a "Non-U.S. Lender") shall deliver to the Borrower and the Administrative Agent (and, in the case of a Participant, to the Lender from which the related participation shall have been purchased) two copies of either U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI or other appropriate form, establishing a complete exemption from withholding of U.S. taxes under Section 871(h) or 881(c) of the Code and a Form W-8BEN, or any subsequent versions thereof or successors thereto properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by the Borrower under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to this Agreement (or, in the case of any Participant, on or before the date such Participant purchases the related participation). In addition, each Non-U.S. Lender shall deliver such 29 forms promptly upon the obsolescence or invalidity of any form previously delivered by such Non-U.S. Lender. Each Non-U.S. Lender shall promptly notify the Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of certification adopted by the U.S. taxing authorities for such purpose). Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall not be required to deliver any form pursuant to this paragraph that such Non-U.S. Lender is not legally able to deliver. (g) A Lender that is entitled to an exemption from or reduction of non-U.S. withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payment under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, 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, provided that such Lender is legally entitled to complete, execute and deliver such documentation and in such Lender's reasonable judgment such completion, execution or submission would not materially prejudice the legal position of such Lender. 2.21 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 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 a mandatory repayment under Section 2.12 in accordance with the provisions of this Agreement or an optional prepayment after the Borrower has given notice thereof or (c) the making of a repayment of Eurodollar Loans on a day that is not the last day of an Interest Period with respect thereto. Such indemnification may include an amount equal to the excess, if any, of (x) the amount of interest that would have accrued on the amount so repaid, or not so borrowed for the period from the date of such prepayment or of such failure to borrow 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 Term Loans provided for herein over (y) 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. This covenant shall survive the termination of this Agreement and the payment of the Obligations in full. 2.22 Illegality. Notwithstanding any other provision in this Agreement, 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 shall forthwith be canceled and (b) such Lender's Term Loans then outstanding as Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans on the respective last days of the then current Interest Periods with respect to such Term Loans or within such earlier period as required by law. If any such conversion of a Eurodollar Loan occurs on a day 30 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 2.21. 2.23 Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.19, 2.20(a) or 2.22 with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Term Loans affected by such event with the object of avoiding the consequences of such event; provided that such designation is made on terms that, in the sole judgment of such Lender, cause such Lender and its lending office(s) to suffer no economic, legal or regulatory disadvantage, and provided further that nothing in this Section shall affect or postpone any of the obligations of any Borrower or the rights of any Lender pursuant to Section 2.19, 2.20(a) or 2.22. SECTION 3 - [INTENTIONALLY OMITTED] SECTION 4 - REPRESENTATIONS AND WARRANTIES To induce the Arranger, the Agents and the Lenders to enter into this Agreement and to make the Term Loans, each of Parent, Holdings and the Borrower hereby represent and warrant to the Arranger, each Agent and each Lender that: 4.1 Financial Condition. (a) The unaudited pro forma consolidated balance sheet of the Borrower and its consolidated Subsidiaries as at June 30, 2002 (the "Pro Forma Balance Sheet"), copies of which have heretofore been furnished to each Original Lender, has been prepared giving effect (as if such events had occurred on such date) to (i) the Term Loans to be made on the Closing Date and the use of proceeds thereof and (ii) the payment of fees and expenses in connection with the foregoing. The Pro Forma Balance Sheet has been prepared based on the best information available to the Borrower as of the date of delivery thereof, and presents fairly on a pro forma basis the estimated financial position of Borrower and its consolidated Subsidiaries as at June 30, 2002, assuming that the events specified in the preceding sentence had actually occurred at such date. (b) The consolidated balance sheet of the Borrower and its Subsidiaries as at December 31, 2001, and the related consolidated statements of income and of cash flows for the fiscal year ended on such date present fairly the consolidated financial condition of the Borrower and its Subsidiaries as at such date, and the consolidated results of its operations and its consolidated cash flows for the fiscal year then ended. The unaudited consolidated balance sheet of the Borrower and its Subsidiaries as at June 30, 2002, and the related unaudited consolidated statements of income and cash flows for the six-month period ended on such date, present fairly the consolidated financial condition of the Borrower and its Subsidiaries as at such date, and the consolidated results of their operations and their consolidated cash flows for the six-month period then ended (subject to normal year-end audit adjustments). All such financial statements, including any related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved. Except as set forth in Schedule 4.1(a), the Borrower and its Subsidiaries do not have any material Guarantee Obligations, contingent liabilities and liabilities for taxes, or any long-term leases or unusual forward or long-term commitments, including, without limitation, any interest rate 31 or foreign currency swap or exchange transaction or other obligation in respect of derivatives, that are not reflected in the most recent financial statements referred to in this paragraph. Except as set forth on Schedule 4.1(b), during the period from June 30, 2002 to and including the date hereof there has been no Disposition by the Borrower or any of its Subsidiaries of any material part of its business or Property. 4.2 No Change. Since June 30, 2002, there has been no development or event that has had or could reasonably be expected to have a Material Adverse Effect (except as to Parent and as disclosed in Parent's filings with the Securities and Exchange Commission pursuant to Section 13(a) of the Securities Exchange Act of 1934, as amended). 4.3 Existence; Compliance with Law. Each of Parent, Holdings, the Borrower and its Subsidiaries (a) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, (b) has the power and authority, and the legal right, to own and operate its Property, to lease the Property it operates as lessee and to conduct the business in which it is currently engaged, including the Oil and Gas Business, (c) is duly qualified as a foreign entity and in good standing under the laws of each jurisdiction where its ownership, lease or operation of Property or the conduct of its business requires such qualification and (d) is in compliance with all Requirements of Law except to the extent that the failure to comply therewith could not, in the aggregate, reasonably be expected to have a Material Adverse Effect. 4.4 Power; Authorization; Enforceable Obligations. Parent and each Loan Party has the 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 borrow hereunder. Parent and each Loan Party has taken all necessary corporate, partnership, limited liability company or other 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 borrowings 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 borrowings hereunder or with the execution, delivery, performance, validity or enforceability of this Agreement or any of the Loan Documents, except (a) consents, authorizations, filings and notices described in Schedule 4.4, which consents, authorizations, filings and notices have been obtained or made and are in full force and effect and (b) the filings referred to in Section 4.19. Each Loan Document has been duly executed and delivered on behalf of Parent and each Loan Party to the extent it is a party thereto. This Agreement constitutes, and each other Loan Document upon execution will constitute, a legal, valid and binding obligation of Parent and each Loan Party to the extent it is a party thereto, enforceable against Parent and 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). 4.5 No Legal Bar. The execution, delivery and performance of this Agreement, the other Loan Documents, the borrowings hereunder and the use of the proceeds thereof will not violate any Requirement of Law or any Contractual Obligation of Parent (or a Subsidiary thereof, 32 other than Holdings, the Borrower or any of the Borrower's Subsidiaries), Holdings, the Borrower or any of the Borrower's Subsidiaries 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 Parent, Holdings, the Borrower or any of its Subsidiaries could reasonably be expected to have a Material Adverse Effect. 4.6 No Material Litigation. Except as set forth in Schedule 4.6, no litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of Parent, Holdings or the Borrower, threatened by or against Parent, Holdings, the Borrower or any of the Borrower's Subsidiaries or against any of their respective properties or revenues (a) with respect to any of the Loan Documents or any of the transactions contemplated hereby or thereby or (b) that could reasonably be expected to have a Material Adverse Effect. 4.7 No Default. None of Parent, Holdings, the Borrower or any of the Borrower's Subsidiaries is in default under or with respect to any of its Contractual Obligations in any respect that could reasonably be expected to have a Material Adverse Effect and no Default or Event of Default has occurred and is continuing. 4.8 Ownership of Property; Liens. Each of Holdings, the Borrower and the Borrower's Subsidiaries is the sole owner of, legally and beneficially, and has good and defensible title in fee simple to, or a valid leasehold interest in, all its real property , including, those subject to the Mortgages, free and clear of Liens other than Permitted Liens. 4.9 Intellectual Property. Holdings, the Borrower and each of the Borrower's Subsidiaries 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 or 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 Parent, Holdings or the Borrower know of any valid basis for any such claim. The use of Intellectual Property by Holdings, the Borrower and the Borrower's Subsidiaries does not infringe on the rights of any Person in any material respect. 4.10 Taxes. Each of Parent, Holdings, the Borrower and each of their respective Subsidiaries has filed or caused to be filed all federal, state and other material 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 material assessments made against it or any of its Property and all other material taxes, fees or other charges imposed on it or any of its Property by any Governmental Authority (other than any taxes, 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 Parent, Holdings, the Borrower or any of their respective Subsidiaries, as the case may be); the contents of all such material tax returns are correct and complete in all material respects, no tax Lien has been filed, and, to the knowledge of Parent, Holdings and the Borrower, no claim is being asserted, with respect to any such tax, fee or other charge (other than any Liens or claims, the amount or validity of which are currently being contested in good faith by appropriate proceedings and with respect to which reserves 33 in conformity with GAAP have been provided on the books of Parent, Holdings, the Borrower or any of their respective Subsidiaries, as the case may be). 4.11 Federal Regulations. No part of the proceeds of the Term Loans will be used for purchasing or carrying any "margin stock" (within the meaning of Regulation U) or for the purpose of purchasing, carrying or trading in any securities under such circumstances as to involve the Borrower in a violation of Regulation X or to involve any broker or dealer in a violation of Regulation T. No indebtedness being reduced or retired out of the proceeds of the Term Loans was or will be incurred for the purpose of purchasing or carrying any "margin stock" (within the meaning of Regulation U).

Each Lender represents to the Arranger and the Agents that it has, independently and without reliance upon the Arranger or any Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition, prospects and creditworthiness of Parent or the Loan Parties and their Affiliates and made its own decision to make its Term Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon the Arranger or any Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition, prospects and creditworthiness of Parent or the Loan Parties and their affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, neither the Arranger nor any Agent shall have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of Parent or any Loan Party or any Affiliate of Parent or a Loan Party that may come into the possession of the Arranger or such Agent or any of its officers, directors, employees, agents, attorneys and other advisors, partners, attorneys-in-fact or affiliates. 65 9.7 Indemnification. The Lenders agree to indemnify the Arranger and each Agent in its capacity as such (to the extent not reimbursed by Holdings or the Borrower and without limiting the obligation of Holdings or the Borrower to do so), ratably according to their respective Term Loan Percentages in effect on the date on which indemnification is sought under this Section (or, if indemnification is sought after the date upon which the Commitments shall have terminated and the Term Loans shall have been paid in full, ratably in accordance with such Term Loan Percentages immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (including, without limitation, at any time following the payment of the Term Loans) be imposed on, incurred by or asserted against the Arranger or such Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Arranger or such Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and non-appealable decision of a court of competent jurisdiction to have resulted solely and proximately from the Arranger's or such Agent's gross negligence or willful misconduct in breach of a duty owed to such Lender. The agreements in this Section 9.7 shall survive the payment of the Term Loans and all other amounts payable hereunder. 9.8 Arranger and Agents in Their Individual Capacities. The Arranger and each Agent and their respective Affiliates may make loans to, accept deposits from and generally engage in any kind of business with Parent or any Loan Party as though the Arranger was not the Arranger and such Agent was not an Agent. With respect to its Term Loans made or renewed by it, the Arranger and each Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not the Arranger or an Agent, as the case may be, and the terms "Lender" and "Lenders" shall include the Arranger and each Agent in their respective individual capacities. 9.9 Successor Agents. The Administrative Agent may resign as Administrative Agent upon 10 days' notice to the Lenders and the Borrower. If the Administrative Agent shall resign as Administrative Agent under this Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall (unless an Event of Default under Section 8(a) or Section 8(f) with respect to the Borrower shall have occurred and be continuing) be subject to approval by the Borrower (which approval shall not be unreasonably withheld or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and the term "Administrative Agent" shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent's rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Term Loans. If no successor agent has accepted appointment as Administrative Agent by the date that is 10 days following a retiring Administrative Agent's notice of resignation, the retiring Administrative Agent's resignation shall nevertheless thereupon become effective, and the Lenders shall assume and perform all of the duties of the 66 Administrative Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above. The Syndication Agent may, at any time, by notice to the Lenders and the Administrative Agent, resign as Syndication Agent hereunder, whereupon the duties, rights, obligations and responsibilities of the Syndication Agent hereunder shall automatically be assumed by, and inure to the benefit of, the Administrative Agent, without any further act by the Arranger, the Syndication Agent, the Administrative Agent or any Lender. After any retiring Agent's resignation as Agent, the provisions of this Section 9 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement and the other Loan Documents. 9.10 Authorization to Release Liens. The Administrative Agent is hereby irrevocably authorized by each of the Lenders to release any Lien covering any Property of the Borrower or any of the Borrower's Subsidiaries that is the subject of a Disposition which is permitted by this Agreement or which has been consented to in accordance with Section 10.1. 9.11 The Arranger. The Arranger, in its capacity as such, shall have no duties or responsibilities, and shall incur no liability, under this Agreement and the other Term Loan Documents. (a) To the extent required by any applicable law, the Administrative Agent may withhold from any interest payment to any Lender an amount equivalent to any applicable withholding tax. If the forms or other documentation required by Section 2.20(f) are not delivered to the Administrative Agent, then the Administrative Agent may withhold from any interest payment to any Lender not providing such forms or other documentation, an amount equivalent to the applicable withholding tax. (b) If the Internal Revenue Service or any authority of the United States or other jurisdiction asserts a claim that the Administrative Agent did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered, was not properly executed, or because such Lender failed to notify the Administrative Agent of a change in circumstances which rendered the exemption from, or reduction of, withholding tax ineffective, or for any other reason), such Lender shall indemnify the Administrative Agent fully for all amounts paid, directly or indirectly, by the Administrative Agent as tax or otherwise, including penalties and interest, together with all expenses incurred, including legal expenses, allocated staff costs and any out of pocket expenses. (c) If any Lender sells, assigns, grants a participation in, or otherwise transfers its rights under this Agreement, the purchaser, assignee, participant or transferee, as applicable, shall comply and be bound by the terms of Sections 2.20(f) and 9.12. SECTION 10 - MISCELLANEOUS 10.1 Amendments and Waivers. Neither this Agreement nor any other Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this Section 10.1.

Any such waiver and any such amendment, supplement or modification shall apply equally to each of the Lenders and shall be binding upon Parent and the Loan Parties, the Lenders, the Agents, the Arranger and all future holders of the Term Loans. In the case of any waiver, Parent, the Loan Parties, the Lenders, the Arranger and the Agents shall be restored to their former position and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon. Any such waiver, amendment, supplement or modification shall be effected by a written instrument signed by the parties required to sign pursuant to the foregoing provisions of this Section; provided that delivery of an executed signature page of any such instrument by facsimile transmission shall be effective as delivery of a manually executed counterpart thereof. Notwithstanding anything in this Agreement or the other Loan Documents to the contrary, the Administrative Agent shall be authorized to release the Mortgages on the Oil and Gas Properties permitted to be sold, exchanged or traded under Section 7.5(e), (f) or (g) of this Agreement without any further action by the Lenders. 10.2 Notices.

The Borrower agrees (a) to pay or reimburse the Arranger, the Agents and the Lenders for all their reasonable out-of-pocket costs and expenses incurred in connection with the syndication of the Facility (other than fees payable to syndicate members) and the development, preparation and execution of, and any amendment, supplement or modification to, this Agreement and the other Loan Documents and any other documents prepared in connection herewith or therewith, and the consummation and administration of the transactions contemplated hereby and thereby, including, without limitation, the reasonable fees and disbursements and other charges of counsel and other consultants to each of the Arranger, the Administrative Agent, the Original Lenders and the 70 Syndication Agent and the charges of IntraLinks, (b) to pay or reimburse each Lender, the Arranger and each Agent for all its costs and expenses incurred in connection with the enforcement or preservation of any rights under this Agreement, the other Loan Documents and any such other documents, including, without limitation, the fees and disbursements of counsel (including the allocated fees and disbursements and other charges of in-house counsel) to each Lender and of counsel to the Arranger and each Agent and the charges of IntraLinks, (c) to pay, indemnify, and hold each Lender, the Arranger and the Agents harmless from, any and all recording and filing fees and any and all liabilities with respect to, or resulting from any delay in paying, stamp, excise and other taxes, if any, which may be payable or determined to be payable in connection with the execution and delivery of, or consummation or administration of any of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver or consent under or in respect of, this Agreement, the other Loan Documents and any such other documents, and (d) to pay, indemnify, and hold each Lender, the Arranger, each Agent, their respective Affiliates, and their respective officers, directors, partners, trustees, employees, affiliates, shareholders, attorneys and other advisors, agents, attorneys-in-fact and controlling persons (each, an "Indemnitee") harmless from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to or arising out of the execution, delivery, enforcement, performance and administration of this Agreement, the other Loan Documents and any such other documents, including, without limitation, any of the foregoing relating to the use of proceeds of the Term Loans, the violation of, noncompliance with or liability under, any Environmental Law applicable to the operations of any Loan Party or any of the Properties or the use by unauthorized persons of information or other materials sent through electronic, telecommunications or other information transmission systems that are intercepted by such persons and the fees and disbursements and other charges of legal counsel in connection with claims, actions or proceedings by any Indemnitee against the Borrower hereunder (all the foregoing in this clause (d), collectively, the "Indemnified Liabilities"); provided that the Borrower shall have no obligation hereunder to any Indemnitee with respect to Indemnified Liabilities to the extent such Indemnified Liabilities are found by a final and non-appealable decision of a court of competent jurisdiction to have resulted solely and proximately from the gross negligence or willful misconduct of such Indemnitee in breach of a duty owed to the Borrower. Without limiting the foregoing, and to the extent permitted by applicable law, each of Holdings and the Borrower agrees not to assert, and the Borrower agrees to cause its Subsidiaries not to assert, and each of Holdings and the Borrower hereby waives, and the Borrower agrees to cause the its Subsidiaries so to waive, all rights for contribution or any other rights of recovery with respect to all claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses of whatever kind or nature, under or related to Environmental Laws, that any of them might have by statute or otherwise against any Indemnitee.

Statements payable by the Borrower pursuant to this Section shall be submitted to the Borrower in accordance with Section 10.2, or to such other Person or address as may be hereafter designated by the Borrower in a written notice to the Administrative Agent. The agreements in this Section shall survive repayment of the Term Loans and all other amounts payable hereunder. 71 10.6 Successors and Assigns; Participations and Assignments. (a) This Agreement shall be binding upon and inure to the benefit of Parent, Holdings, the Borrower, the Lenders, the Arranger, the Agents, all future holders of the Term Loans and their respective successors and assigns, except that none of Parent, Holdings or the Borrower may assign or transfer any of their respective rights or obligations under this Agreement without the prior written consent of the Arranger, the Agents and each Lender. (b) Any Lender may, without the consent of the Borrower or any other Person, in accordance with applicable law, at any time sell to one or more banks, financial institutions or other entities (each, a "Participant") participating interests in any Term Loan owing to such Lender, any Commitment of such Lender or any other interest of such Lender hereunder and under the other Loan Documents. In the event of any such sale by a Lender of a participating interest to a Participant, such Lender's obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Term Loan for all purposes under this Agreement and the other Loan Documents, and the Borrower, the Arranger and the Agents shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement and the other Loan Documents. In no event shall any Participant under any such participation have any right to approve any amendment or waiver of any provision of any Loan Document, or any consent to any departure by Parent or any Loan Party therefrom, except to the extent that such amendment, waiver or consent would reduce the principal of, or interest on, the Term Loans or any fees payable hereunder, or postpone the date of the final maturity of the Term Loans, in each case to the extent subject to such participation. The Borrower agrees that if amounts outstanding under this Agreement and the Term Loans are due or unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall, to the maximum extent permitted by applicable law, be deemed to have the right of setoff in respect of its participating interest in amounts owing under this Agreement to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement; provided that, in purchasing such participating interest, such Participant shall be deemed to have agreed to share with the Lenders the proceeds thereof as provided in Section 10.7(a) as fully as if it were a Lender hereunder. The Borrower also agrees that each Participant shall be entitled to the benefits of Sections 2.19, 2.20 and 2.21 with respect to its participation in the Commitments and the Term Loans outstanding from time to time as if it was a Lender; provided that, in the case of Section 2.20, such Participant shall have complied with the requirements of said Section and provided further, that no Participant shall be entitled to receive any greater amount pursuant to any such Section than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred by such transferor Lender to such Participant had no such transfer occurred. (c) Any Lender (an "Assignor") may, in accordance with applicable law and upon written notice to the Syndication Agent, at any time and from time to time assign to any Lender any affiliate thereof or Affiliated Fund of the assigning Lender or of another Lender or, with the consent of the Borrower and the Agents (which, in each case, shall not be unreasonably withheld or delayed) (provided that (x) no such consent need be obtained by a Lehman Entity for a period of 180 days following the Closing Date and (y) the consent of the Borrower need not be 72 obtained with respect to any assignment of Term Loans), to an additional bank, financial institution or other entity (an "Assignee") all or any part of its rights and obligations under this Agreement pursuant to an Assignment and Acceptance, substantially in the form of Exhibit E (an "Assignment and Acceptance"), executed by such Assignee and such Assignor (and, where the consent of the Borrower or the Agents is required pursuant to the foregoing provisions, by the Borrower and such other Persons) and delivered to the Administrative Agent for its acceptance and recording in the Register; provided that no such assignment to an Assignee (other than any Lender or any affiliate thereof or Affiliated Fund) shall be in an aggregate principal amount of less than $10,000,000, unless otherwise agreed by the Borrower, the Syndication Agent and the Administrative Agent. Any such assignment need not be ratable as among the Facility. Upon such execution, delivery, acceptance and recording, from and after the effective date determined pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Lender hereunder with Term Loans as set forth therein, and (y) the Assignor thereunder shall, to the extent provided in such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of an Assignor's rights and obligations under this Agreement, such Assignor shall cease to be a party hereto). Notwithstanding any provision of this Section, the consent of the Borrower shall not be required for any assignment that occurs at any time when any Event of Default shall have occurred and be continuing. (d) The Administrative Agent shall, on behalf of the Borrower, maintain at its address referred to in Section 10.2 a copy of each Assignment and Acceptance delivered to it and a register (the "Register") for the recordation of the names and addresses of the Lenders and the principal amount of, and interest accrued on, the Term Loans owing to each Lender from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register as the owner of the Term Loans and any Term Notes evidencing such Term Loans recorded therein for all purposes of this Agreement. Any assignment of any Term Loan, whether or not evidenced by a Term Note, shall be effective only upon appropriate entries with respect thereto being made in the Register (and each Term Note shall expressly so provide). Any assignment or transfer of all or part of a Term Loan evidenced by a Term Note shall be registered on the Register only upon surrender for registration of assignment or transfer of the Term Note evidencing such Term Loan, accompanied by a duly executed Assignment and Acceptance; thereupon one or more new Term Notes in the same aggregate principal amount shall be issued to the designated Assignee, and the old Term Notes shall be returned by the Administrative Agent to the Borrower marked "canceled". The Register shall be available for inspection by the Borrower or any Lender (with respect to any entry relating to such Lender's Term Loans) at any reasonable time and from time to time upon reasonable prior notice. (e) Upon its receipt of an Assignment and Acceptance executed by an Assignor and an Assignee (and, in any case where the consent of any other Person is required by Section 10.6(c), by each such other Person) together with payment to the Administrative Agent of a registration and processing fee of $3,500 (except that no such registration and processing fee shall be payable (y) in connection with an assignment by or to an Original Lender) or (z) in the case 73 of an Assignee which is already a Lender or is an affiliate of a Lender or an Affiliated Fund), the Administrative Agent shall (i) promptly accept such Assignment and Acceptance and (ii) on the effective date determined pursuant thereto record the information contained therein in the Register and give notice of such acceptance and recordation to the Borrower. On or prior to such effective date, the Borrower, at its own expense, upon request, shall execute and deliver to the Administrative Agent (in exchange for the applicable Term Notes, as the case may be, of the assigning Lender) new applicable Term Notes to such Assignee or its registered assigns in an amount equal to the applicable Term Loans, assumed or acquired by it pursuant to such Assignment and Acceptance and, if the Assignor has retained Term Loans, upon request, new Term Notes, to the Assignor or its registered assigns in an amount equal to the applicable Term Loans, as the case may be, retained by it hereunder. Such new Term Note or Term Notes shall be dated the Closing Date and shall otherwise be in the form of the Term Note or Term Notes replaced thereby. (e) For the avoidance of doubt, the parties to this Agreement acknowledge that the provisions of this Section concerning assignments of Term Loans and Term Notes relate only to absolute assignments and that such provisions do not prohibit assignments creating security interests, including, without limitation, any pledge or assignment by a Lender of any Term Loan or Term Note to any Federal Reserve Bank in accordance with applicable law. 10.7 Adjustments; Set-off. (a) Except to the extent that this Agreement provides for payments to be allocated to a particular Lender or to the Lenders, if any Lender (a "Benefited Lender") shall at any time receive any payment of all or part of the Obligations owing to it, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 8(f), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of such other Lender's Obligations, such Benefited Lender shall purchase for cash from the other Lenders a participating interest in such portion of each such other Lender's Obligations, or shall provide such other Lenders with the benefits of any such collateral, as shall be necessary to cause such Benefited Lender to share the excess payment or benefits of such collateral ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such Benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. (b) In addition to any rights and remedies of the Lenders provided by law, each Lender shall have the right, without prior notice to Holdings or the Borrower, any such notice being expressly waived by the Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by the Borrower hereunder (whether at the stated maturity, by acceleration or otherwise), to set off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of the Borrower. Each Lender agrees to notify promptly the Borrower and the Administrative Agent after any such setoff and application made by such Lender; provided that the failure to give such notice shall not affect the validity of such setoff and application. 74 10.8 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of an executed signature page of this Agreement by facsimile transmission shall be effective as delivery of a manually executed counterpart hereof. A set of the copies of this Agreement signed by all the parties shall be lodged with the Borrower and the Administrative Agent. 10.9 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. 10.10 Integration. This Agreement and the other Loan Documents represent the agreement of Parent, Holdings, the Borrower, the Agents, the Arranger and the Lenders with respect to the subject matter hereof, and there are no promises, undertakings, representations or warranties by the Arranger, any Agent or any Lender relative to the subject matter hereof not expressly set forth or referred to herein or in the other Loan Documents. 10.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK. 10.12 Submission To Jurisdiction; Waivers. Each of Parent, Holdings and the Borrower hereby irrevocably and unconditionally: (a) submits for itself and its Property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts of the State of New York, the courts of the United States of America for the Southern District of New York, and appellate courts from any thereof; (b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same; (c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to Parent, Holdings or the Borrower, as the case may be, at its address set forth in Section 10.2 or at such other address of which the Administrative Agent shall have been notified pursuant thereto; (d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and 75 (e) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section any special, exemplary, punitive or consequential damages. 10.13 Suretyship Waivers. Each of Holdings and the Borrower hereby waives any and all defenses applicable or available to guarantors or sureties whether arising as a result of the joint and several nature of the obligations of Parent, Holdings and the Borrower hereunder or otherwise. Without limiting the generality of the foregoing, the waivers of the Guarantors (as defined in the Guarantee and Collateral Agreement) set forth in Section 2.5 of the Guarantee and Collateral Agreement are hereby incorporated herein by this reference mutatis mutandis and such waivers shall be deemed to be made by Parent, Holdings and the Borrower hereunder as if such waivers had been expressly set forth herein. 10.14 Acknowledgments. Each of Parent, 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 Arranger, any Agent nor any Lender has any fiduciary relationship with or duty to Parent, Holdings or the Borrower arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between the Arranger, the Agents and Lenders, on one hand, and Parent, 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 Arranger, the Agents and the Lenders or among Parent, Holdings, the Borrower and the Lenders. 10.15 Confidentiality.

In the event that any "Accounting Change" (as defined below) shall occur and such change results in a change in the method of calculation of financial covenants, standards or terms in this Agreement, then Parent, Holdings, the Borrower and the Administrative Agent agree to enter into negotiations in order to amend such provisions of this Agreement so as to equitably reflect such Accounting Changes with the desired result that the criteria for evaluating the Borrower's Subsidiaries' financial condition shall be the same after such Accounting Changes as if such Accounting Changes had not been made.
