THE FACILITY AND BORROWING PROCEDURES

SECTION 2.1 Facility. The Lenders grant to the Borrower a credit facility (the “Facility”) pursuant to which, and upon the terms and subject to the conditions herein set out and provided that no Default or Event of Default has occurred and is continuing from time to time on any Business Day, each Lender severally agrees to make Loans in U.S. Dollars to the Borrower equal to such Lender’s Percentage of the aggregate amount of Loans requested by the Borrower to be made on such day.

SECTION 2.1.1 Loans. From time to time on or after the date hereof and prior to the Maturity Date, each Lender shall make Loans under this Section to the Borrower in an aggregate principal amount at any one time outstanding up to but not exceeding such Lender’s Commitment. Subject to the conditions herein, any such Loan repaid prior to the Maturity Date may be reborrowed pursuant to the terms of this Agreement.

SECTION 2.1.2 Availability of Facility. No Lender shall be permitted or required to make (i) any Loan if, after giving effect thereto, the aggregate outstanding principal amount of all Loans of all Lenders would exceed the Commitment Amount, or (ii) any Loan if, after giving effect thereto, the aggregate amount of all Loans of such Lender would exceed the Lender’s Percentage of the Commitment Amount.

SECTION 2.2 Mandatory Reductions of Commitment Amount.

SECTION 2.2.1 On Maturity Date. The Commitment Amount shall be reduced automatically to zero ($0), and all Commitments of the Lenders shall be automatically terminated, on the Maturity Date.

SECTION 2.2.2 At Other Times. Prior to the Maturity Date, the Commitment Amount, and the pro rata portion of the Commitment of each Lender, shall be reduced as follows:

(a) on (A) the last day of each Fiscal Quarter ending June 2008, September 2008, December 2008, and March 2009 by an amount equal to five percent (5%) of the Commitment Amount existing on March 31, 2008 (the “Determination Date”) and (B) the last day of each Fiscal Quarter ending June 2009, September 2009, and December, 2009 by an amount equal to twenty percent (20%) of the Commitment Amount existing on the Determination Date;

(b) by the amount of any Excess Sale Proceeds received by the Borrower and its Subsidiaries in connection with an Asset Sale, such reduction to be made (i) in the case of an Asset Sale having a fair market value in excess of $25,000,000, on the fifth (5th) Business Day after the receipt of any Excess Sale Proceeds, and (ii) in the case of an Asset Sale having a fair market value not in excess of $25,000,000, on the last day of the Fiscal Quarter in which any Excess Sale Proceeds are received; and

(c) on the fifth (5th) Business Day after receipt of such cash proceeds, by the amount of the cash proceeds, minus customary fees, expenses, commissions, discounts and any other reasonable transaction costs incurred in connection therewith, of any issuance on or after the

Effective Date by the Borrower or any of its Restricted Subsidiaries of debt securities in a public offering or in a private placement, in each case (i) only to the extent issued by the Borrower or any of its Restricted Subsidiaries in consideration for cash, (ii) excluding proceeds of revolving credit facilities and similar facilities, (iii) excluding Refinanced Indebtedness, (iv) excluding any debt securities relating to limited-recourse international project financing, and (v) excluding any debt securities issued in consideration for, or the proceeds of which are used to pay or refinance, the purchase price of any acquisition occurring after the Effective Date of any Person or any property.

SECTION 2.3 Voluntary Reductions of Commitment Amount. The Borrower may, from time to time on any Business Day occurring after the Effective Date, voluntarily reduce the amount of the Commitment Amount; provided, however, that all such reductions shall require at least three Business Days’ prior notice to the Administrative Agent and be permanent, and any partial reduction of the Commitment Amount shall be in a minimum amount of $10,000,000 and in an integral multiple of $1,000,000; and provided further that the Borrower shall not reduce the Commitment Amount if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 3.1, the aggregate principal amount of Loans outstanding will exceed the aggregate of the Commitments.

SECTION 2.4 Base Rate Loans and Eurodollar Loans. Subject to the terms and conditions set forth in Article V, each Loan shall be either a Eurodollar Loan or a Base Rate Loan as the Borrower may request, it being understood that Loans made to the Borrower on any date may be either Eurodollar Loans or Base Rate Loans or a combination thereof. As to any Eurodollar Loan, each Lender may, if it so elects, fulfill its commitment to make such Eurodollar Loan by causing its Eurodollar Office to make such Eurodollar Loan; provided, however, that in such event the obligation of the Borrower to repay such Eurodollar Loan nevertheless shall be to such Lender and shall be deemed to be held by such Lender for the account of such Eurodollar Office.

SECTION 2.5 Borrowing Procedures for Loans. The Borrower shall give the Administrative Agent prior written or telegraphic notice pursuant to a Borrowing Request (in substantially the form of Exhibit 2.5 hereto) of each proposed Borrowing or continuation, and as to whether such Borrowing or continuation is to be of Base Rate Loans or Eurodollar Loans, as follows:

SECTION 2.5.1 Base Rate Loans. The Administrative Agent shall receive written or telegraphic notice from the Borrower on or before 2:00 p.m. Central time one (1) Business Day prior to the date of such Borrowing and amount of such Borrowing (which shall be in a minimum amount of $5,000,000 and an integral multiple of $1,000,000), and the Administrative Agent shall advise each Lender thereof promptly thereafter. Not later than 10:00 a.m., Central time, on the date specified in such notice for such Borrowing, each Lender shall provide to the Administrative Agent at the Payment Office, same day or immediately available funds covering such Lender’s Percentage of the requested Base Rate Loan. Upon fulfillment of the applicable conditions set forth in Article V with respect to such Base Rate Loan, the Administrative Agent shall make available to the Borrower the proceeds of each Base Rate Loan (to the extent received from the Lenders) by wire transfer of such proceeds to such account(s) as the Borrower shall have specified in the Borrowing Request.

SECTION 2.5.2 Eurodollar Loans. The Administrative Agent shall receive written or telegraphic notice pursuant to a Borrowing Request from the Borrower on or before 10:00 a.m. Central time, at least three (3) Business Days prior to the date requested for each proposed Borrowing or continuation of a Eurodollar Loan, of the date of such Borrowing or continuation, as the case may be, the amount of such Borrowing or continuation, as the case may be (which shall be in a minimum amount of $5,000,000 and an integral multiple of $1,000,000), and the duration of the initial Eurodollar Interest Period with respect thereto, and the Administrative Agent shall advise each Lender thereof promptly thereafter. Not later than 10:00 a.m., Central time, on the date specified in such notice for such Borrowing, each Lender shall provide to the Administrative Agent at the Payment Office, same day or immediately available funds covering such Lender’s Percentage of the requested Eurodollar Loan. Upon fulfillment of the applicable conditions set forth in Article V with respect to such Eurodollar Loan, the Administrative Agent shall make available to the Borrower the proceeds of each Eurodollar Loan (to the extent received from the Lenders) by wire transfer of such proceeds to such account(s) as the Borrower shall have specified in the Borrowing Request.

SECTION 2.6 Continuation and Conversion Elections. By delivering a Continuation/Conversion Notice to the Administrative Agent on or before 10:00 a.m., Central time, on a Business Day, the Borrower may from time to time irrevocably elect, on not less than three (3) nor more than five (5) Business Days’ notice that all, or any portion in an aggregate minimum amount of $5,000,000 and an integral multiple of $1,000,000 of any Borrowings be, (i) in the case of Base Rate Loans, converted into Eurodollar Loans, or (ii) in the case of Eurodollar Loans, be converted into a Base Rate Loan or continued as a Eurodollar Loan of such Type (in the absence of delivery of a Continuation/Conversion Notice with respect to any Eurodollar Loan at least three (3) Business Days before the last day of the then current Interest Period with respect thereto, such Eurodollar Loan shall, on such last day, automatically convert to a Base Rate Loan); provided, however, that (i) each such conversion or continuation shall be pro rated among the applicable outstanding Loans of all Lenders, and (ii) no portion of the outstanding principal amount of any Loans may be continued as, or be converted into, Eurodollar Loans when any Default has occurred and is continuing.

SECTION 2.7 Funding. Each Lender may, if it so elects, fulfill its obligation to make, continue or convert Eurodollar Loans hereunder by causing one of its foreign branches or Affiliates (or an international banking facility created by such Lender) to make or maintain such Eurodollar Loan; provided, however, that such Eurodollar Loan shall nonetheless be deemed to have been made and to be held by such Lender, and the obligation of the Borrower to repay such Eurodollar Loan shall nevertheless be to such Lender for the account of such foreign branch, Affiliate or international banking facility. In addition, the Borrower hereby consents and agrees that, for purposes of any determination to be made for purposes of Sections 4.1, 4.2, 4.3 or 4.4, it shall be conclusively assumed that each Lender elected to fund all Eurodollar Loans by purchasing, as the case may be, Dollar deposits in its Eurodollar Office’s interbank eurodollar market.

SECTION 2.8 Repayment of Loans; Evidence of Debt.

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

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

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

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

(e) Any Lender may request that Loans made by it be evidenced by a promissory note, in substantially the form attached as Exhibit 2.8 hereto. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 10.10.1) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

ARTICLE III
REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

SECTION 3.1 Repayments and Prepayments. The Borrower shall repay in full the unpaid principal amount of each Loan on the Maturity Date. Prior thereto, the Borrower

(a) may, from time to time on any Business Day, make a voluntary prepayment, in whole or in part, of the outstanding principal amount of any Loans; provided, however, that (i) any such prepayment shall be applied to the Lenders among Loans having the same Type and, if applicable, having the same Interest Period; (ii) all such voluntary prepayments shall require at least three Business Days’ prior written notice to the Administrative Agent; and (iii) all such voluntary partial prepayments shall be in an minimum amount of $10,000,000 and an integral multiple of $1,000,000;

(b) shall, immediately upon any acceleration of the Maturity Date pursuant to Section 8.2 or Section 8.3, repay all Loans unless, pursuant to Section 8.3, only a portion of all Loans is so accelerated; and

(c) at any time when the aggregate amount of all Loans then outstanding exceeds the Commitment Amount then in effect, shall immediately prepay outstanding Loans in an amount equal to such excess.

Each prepayment of any Loans made pursuant to this Section shall be without premium or penalty, except as may be required by Section 4.4. No voluntary prepayment of principal of any Loans shall cause a reduction in the Commitments or the Commitment Amount.

SECTION 3.2 Interest Provisions. Interest on the outstanding principal amount of Loans shall accrue and be payable in accordance with this Section 3.2.

SECTION 3.2.1 Rates. Pursuant to an appropriately delivered Borrowing Request or Continuation/Conversion Notice, the Borrower may elect that Loans comprising a Borrowing accrue interest at a rate per annum: (a) on that portion maintained from time to time as a Base Rate Loan, equal to the Base Rate from time to time in effect; and (b) on that portion maintained as a Eurodollar Loan, during each Interest Period applicable thereto, equal to the sum of the Eurodollar Rate for such Interest Period plus the Applicable Margin. All Eurodollar Borrowings shall bear interest from and including the first day of the applicable Interest Period to (but not including) the last day of such Interest Period at the interest rate determined as applicable to such Eurodollar Borrowing.

SECTION 3.2.2 Post-Maturity Rates. After the date any principal amount of any Loan is due and payable (whether on the Maturity Date, upon acceleration or otherwise), or after any other monetary Obligation of the Borrower shall have become due and payable, the Borrower shall pay, but only to the extent permitted by law, interest (after as well as before judgment) on such amounts at a rate per annum equal to the Base Rate plus the Default Margin.

SECTION 3.2.3 Payment Dates. Interest accrued on each Borrowing shall be payable, without duplication on the following dates (each a “Payment Date”): (a) on the Maturity Date; (b) on the date of any payment or prepayment, in whole or in part, of principal outstanding on such Loan on the amount of such principal prepaid or repaid; (c) with respect to Base Rate Loans, on each Quarterly Payment Date occurring after the Effective Date; (d) with respect to Eurodollar Borrowings, on the last day of each applicable Interest Period (and, if such Interest Period shall exceed three months, every three months from the first day of such Interest Period); (e) with respect to any portion of Base Rate Loans converted into Eurodollar Loans on a day when interest would not otherwise have been payable pursuant to clause (c), on the date of such conversion; and (f) on that portion of any Borrowings the Maturity Date of which is accelerated pursuant to Section 8.2 or Section 8.3, immediately upon such acceleration.

SECTION 3.3 Fees. The Borrower agrees to pay the fees set forth in this Section 3.3. All such fees shall be non-refundable.

SECTION 3.3.1 Facility Fee. Commencing on the Initial Borrowing Date, the Borrower agrees to pay to the Administrative Agent for the account of each Lender a facility fee

in an amount equal to the product of the Applicable Facility Fee Rate times such Lender’s Percentage times the Commitment Amount. Accrued facility fees shall be payable in arrears on each Quarterly Payment Date thereafter and on the Maturity Date.

SECTION 3.3.2 Ticking Fee. The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee for the period from the Effective Date to, but not including, the earlier to occur of (i) the Initial Borrowing Date or (ii) the date of the termination of the Commitments pursuant to the terms of Section 2.3 of this Agreement, calculated at the rate of 0.075% per annum on the total amount of the Commitment of each Lender. The ticking fee shall be payable on the earlier to occur of (i) the Initial Borrowing Date or (ii) the date of the termination of the Commitments pursuant to the terms of Section 2.3 of this Agreement.

SECTION 3.3.3 Fees. The Borrower agrees to pay on the Initial Borrowing Date to the Administrative Agent for its own account and for the account of each Lender and Arranger, respectively, all fees that are then due pursuant to that certain fee letter, dated December 15, 2004, between the Borrower, the Administrative Agent and X.X. Xxxxxx Securities Inc., as amended from time to time (the “Fee Letter”), including, without limitation, any upfront fees.

SECTION 3.3.4 Payment Office. The Borrower shall make all payments to the Administrative Agent at the Payment Office.

ARTICLE IV
CERTAIN EURODOLLAR AND OTHER PROVISIONS

SECTION 4.1 Eurodollar Lending Unlawful. If any Lender shall determine (which determination shall, upon notice thereof to the Borrower and the Lenders, be conclusive and binding on the Borrower) that the introduction of or any change in or in the interpretation of any law makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for such Lender to make, continue or maintain any Borrowing as, or to convert any Borrowing into, a Eurodollar Borrowing, the obligations of such Lender to make, continue, maintain or convert any such Borrowings shall, upon such determination, forthwith be suspended until such Lender shall notify the Administrative Agent that the circumstances causing such suspension no longer exist, and all Eurodollar Borrowings shall automatically convert into Base Rate Loans at the end of the then current Interest Periods with respect thereto or sooner, if required by such law or assertion; provided, however, that the obligation of such Lender to make, continue, maintain or convert any such Eurodollar Borrowings shall remain unaffected if such Lender can designate a different Eurodollar Office for the making, continuance, maintenance or conversion of Eurodollar Borrowings and such designation will not, in the sole discretion of such Lender, be otherwise disadvantageous to such Lender.

SECTION 4.2 Deposits Unavailable or Eurodollar Interest Rate Unascertainable. If the Administrative Agent shall have determined that, by reason of circumstances affecting the Administrative Agent’s relevant market, adequate means do not exist for ascertaining the interest rate applicable hereunder to Eurodollar Borrowings, then, upon notice from the Administrative Agent to the Borrower and the Lenders, the obligations of all Lenders under Section 2.5.2 and Section 2.6 to make or continue any Borrowings as, or to convert any Borrowings into,

Eurodollar Borrowings shall forthwith be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

SECTION 4.3 Increased Eurodollar Borrowing Costs, etc. The Borrower agrees to reimburse each Lender for any increase in the cost to such Lender of, or any reduction in the amount of any sum receivable by such Lender in respect of, making, continuing or maintaining (or of its obligation to make, continue or maintain) any Borrowings as, or of converting (or of its obligation to convert) any Borrowings into, Eurodollar Borrowings. Such Lender shall promptly notify the Administrative Agent and the Borrower in writing of the occurrence of any such event, such notice to state, in reasonable detail, the reasons therefor and the additional amount required fully to compensate such Lender for such increased cost or reduced amount; provided, however, that such Lender shall designate a different Eurodollar Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole discretion of such Lender, be otherwise disadvantageous to such Lender. Such additional amounts shall be payable by the Borrower directly to such Lender within fifteen days of its receipt of such notice, and such notice shall be rebuttable presumptive evidence of the amount payable by the Borrower.

SECTION 4.4 Funding Losses. In the event any Lender shall incur any loss or expense (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to make, continue or maintain any portion of the principal amount of any Borrowing as, or to convert any portion of the principal amount of any Borrowing into, a Eurodollar Borrowing) as a result of (a) any conversion or repayment or prepayment of the principal amount of any Eurodollar Borrowings on a date other than the scheduled last day of the Interest Period applicable thereto, whether pursuant to Section 3.1 or otherwise, (b) any Borrowings not being made as Eurodollar Borrowings in accordance with the Borrowing Request therefor, (c) any Borrowings not being continued as, or converted into, Eurodollar Borrowings in accordance with the Continuation/Conversion Notice, or (d) the assignment of any Eurodollar Borrowing other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 4.10, then, upon the written notice of such Lender to the Borrower (with a copy to the Administrative Agent), the Borrower shall, within fifteen days of its receipt thereof, pay directly to such Lender such amount as will (in the reasonable determination of such Lender) reimburse such Lender for such loss or expense. Such written notice (which shall include calculations in reasonable detail) shall be rebuttable presumptive evidence of the amount payable by the Borrower.

SECTION 4.5 Increased Capital Costs. If any change in, or the introduction, adoption, effectiveness, interpretation, reinterpretation or phase-in of, any law or regulation, directive, guideline, decision or request (whether or not having the force of law) of any court, central bank, regulator or other governmental authority affects or would affect the amount of capital required or expected to be maintained by any Lender or any Person controlling such Lender, and such Lender determines (in its sole discretion) that the rate of return on its or such controlling Person’s capital as a consequence of its Commitments or the Borrowings made by such Lender is reduced to a level below that which such Lender or such controlling Person could have achieved but for the occurrence of any such circumstance, then, in any such case upon notice from time to time by such Lender to the Borrower, the Borrower shall pay directly to such Lender, within fifteen days, additional amounts sufficient to compensate such Lender or such controlling Person for such reduction in rate of return; provided, however, that such Lender shall

designate a different Domestic or Eurodollar Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole discretion of such Lender, be otherwise disadvantageous to such Lender. A statement of such Lender as to any such additional amount or amounts (including calculations thereof in reasonable detail) shall be rebuttable presumptive evidence of the amount payable by the Borrower. In determining such amount, such Lender may use any reasonable method of averaging and attribution that it (in its sole discretion) shall deem applicable.

SECTION 4.6 Taxes. All payments by the Borrower of principal of, and interest on, the Borrowings and all other amounts payable hereunder shall be made free and clear of and without deduction for any present or future income, excise, stamp or franchise taxes and other taxes, fees, duties, withholdings or other charges of any nature whatsoever imposed by any taxing authority, but excluding franchise taxes and taxes imposed on or measured by any Lender’s net income or receipts (such non-excluded items being called “Taxes”). In the event that any withholding or deduction from any payment to be made by the Borrower hereunder is required in respect of any Taxes pursuant to any applicable law, rule or regulation, then the Borrower will, within fifteen days (a) pay directly to the relevant authority the full amount required to be so withheld or deducted; (b) promptly forward to the Administrative Agent an official receipt or other documentation satisfactory to the Administrative Agent evidencing such payment to such authority; and (c) pay to the Administrative Agent for the account of the Lenders such additional amount or amounts as is necessary to ensure that the net amount actually received by each Lender will equal the full amount such Lender would have received had no such withholding or deduction been required.

If any Taxes are directly asserted against the Administrative Agent or any Lender with respect to any payment received by the Administrative Agent or such Lender hereunder, the Administrative Agent or such Lender may pay such Taxes and the Borrower will promptly pay such additional amounts (including any penalties, interest or expenses) as is necessary in order that the net amount received by such person after the payment of such Taxes (including any Taxes on such additional amount) shall equal the amount such person would have received had not such Taxes been asserted; provided that the Borrower will not be obligated to pay such additional amounts to the Administrative Agent or such Lender to the extent that such additional amounts shall have been incurred as a consequence of the Administrative Agent’s or such Lender’s gross negligence or willful misconduct, as the case may be.

If the Borrower fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent, for the account of the respective Lenders, the required receipts or other required documentary evidence, the Borrower shall indemnify the Lenders for any incremental Taxes, interest or penalties that may become payable by any Lender as a result of any such failure. For purposes of this Section, a distribution hereunder by the Administrative Agent or any Lender to or for the account of any Lender shall be deemed a payment by the Borrower.

Each Lender that is organized under the laws of a jurisdiction other than the United States shall, prior to the due date of any payments of the Loans under this Agreement, execute and deliver to the Borrower and the Administrative Agent, on or about the first scheduled Payment Date in each Fiscal Year, one or more (as the Borrower or the Administrative Agent may

reasonably request) United States Internal Revenue Service Form W-8 BEN or Form W-8 ECI or such other forms or documents (or successor forms or documents), appropriately completed, as may be applicable to establish the extent, if any, to which a payment to such Lender is exempt from withholding or deduction of Taxes, and shall (but only so long as such Lender remains lawfully able to do so) deliver to the Borrower and the Administrative Agent additional copies of such forms on or before the date that such forms expire or become obsolete or after the occurrence of an event requiring a change in the most recent form so delivered by it and such amendments thereto as may be reasonably requested by the Borrower or the Administrative Agent, in each case certifying that such Lender is entitled to benefits under an income tax treaty to which the United States is a party which reduces the rate of withholding tax on payments of interest or fees or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States. If the form provided by a Lender at the time such Lender first becomes a party to this Agreement indicates a United States withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from the definition of “Taxes”. For any period with respect to which a Lender has failed to provide the Borrower and the Administrative Agent with the forms required pursuant to this paragraph, if any (other than if such failure is due to a change in treaty, law or regulation occurring subsequent to the date on which a form originally was required to be provided), such Lender shall not be entitled to indemnification under this Section with respect to Taxes imposed by the United States which Taxes would not have been imposed but for such failure to provide such form; provided, however, that should a Lender, which is otherwise exempt from or subject to a reduced rate of withholding tax, become subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as the Lender shall reasonably request to assist the Lender to recover such Taxes.

If the Borrower is required to pay additional amounts to or for the account of any Lender pursuant to this Section, then such Lender will change the jurisdiction of its applicable Eurodollar or Domestic Office so as to eliminate or reduce any such additional payment which may thereafter accrue if such change, in the sole discretion of such Lender, is not otherwise disadvantageous to such Lender. No Lender shall be entitled to receive any greater payment under this Section as a result of the designation by such Lender of a different applicable Eurodollar or Domestic Office after the date hereof, unless such designation is made with the Borrower’s prior written consent or by reason of the provisions of Sections 4.1, 4.3 or 4.5 requiring such Lender to designate a different applicable Eurodollar or Domestic Office under certain circumstances or at a time when the circumstances giving rise to such greater payment did not exist.

SECTION 4.7 Special Fees in Respect of Reserve Requirements. With respect to Eurodollar Borrowings, the Borrower agrees to pay to each Lender on appropriate Payment Dates, as additional interest, such amounts as will compensate such Lender for any cost to such Lender, from time to time, of any reserve, special deposit, special assessment or similar capital requirements against assets of, deposits with or for the account of, or credit extended by, such Lender which are imposed on, or deemed applicable by, such Lender, from time to time, under or pursuant to (i) any Law, treaty, regulation or directive now or hereafter in effect (including, without limitation, Regulation D of the Board of Governors of the Federal Reserve System but excluding any reserve requirement included in the definition of Eurodollar Rate in Section 1.1), (ii) any interpretation or application thereof by any governmental authority, agency or

instrumentality charged with the administration thereof or by any court, central bank or other fiscal, monetary or other authority having jurisdiction over the Eurodollar Borrowings or the office of such Lender where its Eurodollar Borrowings are lodged, or (iii) any requirement imposed or requested by any court, governmental authority, agency or instrumentality or central bank, fiscal, monetary or other authority, whether or not having the force of law. A written notice as to the amount of any such cost or any change therein (including calculations, in reasonable detail, showing how such Lender computed such cost or change) shall be promptly furnished by such Lender to the Borrower and shall be rebuttable presumptive evidence of such cost or change. The Borrower will not be responsible for paying any amounts pursuant to this Section accruing prior to 180 days prior to the receipt by the Borrower of the written notice referred to in the preceding sentence. Within fifteen (15) days after such certificate is furnished to the Borrower, the Borrower will pay directly to such Lender such additional amount or amounts as will compensate such Lender for such cost or change.

SECTION 4.8 Payments, Computations, etc. Unless otherwise expressly provided, all payments by the Borrower pursuant to this Agreement or any other Loan Document shall be made by the Borrower to the Administrative Agent for the pro rata account of the Lenders entitled to receive such payment. All such payments required to be made to the Administrative Agent shall be made, without setoff, deduction or counterclaim, not later than 11:00 a.m., Central time, on the date due, in same day or immediately available funds, to such account as the Administrative Agent shall specify from time to time by notice to the Borrower. Funds received after that time shall be deemed to have been received by the Administrative Agent on the next succeeding Business Day. The Administrative Agent shall promptly remit in same day funds to each Lender its share, if any, of such payments received by the Administrative Agent for the account of such Lender. All interest and fees shall be computed on the basis of the actual number of days (including the first day but excluding the last day) occurring during the period for which such interest or fee is payable over a year comprised of 360 days (or, in the case of interest on a Base Rate Loan, 365 days or, if appropriate, 366 days). Whenever any payment to be made shall otherwise be due on a day which is not a Business Day, such payment shall (except as otherwise required by clause (c) of the definition of the term “Interest Period” with respect to Eurodollar Loans) be made on the next succeeding Business Day and such extension of time shall be included in computing interest and fees, if any, in connection with such payment.

SECTION 4.9 Sharing of Payments. If any Lender shall obtain any payment or other recovery (whether voluntary, involuntary, by application of setoff or otherwise) on account of any Loan (other than pursuant to the terms of Sections 4.3, 4.4 and 4.5) in excess of its pro rata share of payments then or therewith obtained by all Lenders, such Lender shall purchase from the other Lenders such participations in Loans made by them as shall be necessary to cause such purchasing Lender to share the excess payment or other recovery ratably with each of them; provided, however, that if all or any portion of the excess payment or other recovery is thereafter recovered from such purchasing Lender, the purchase shall be rescinded and each Lender which has sold a participation to the purchasing Lender shall repay to the purchasing Lender the purchase price to the ratable extent of such recovery together with an amount equal to such selling Lender’s ratable share (according to the proportion of (a) the amount of such selling Lender’s required repayment to the purchasing Lender to (b) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing

a participation from another Lender pursuant to this Section may, to the fullest extent permitted by law, exercise all its rights of payment with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a set off to which this Section applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders entitled under this Section to share in the benefits of any recovery on such secured claim.

SECTION 4.10 Replacement of Lender on Account of Increased Costs, Eurodollar Lending Unlawful, Reserve Requirements, Taxes, Certain Dissents, etc. If any Lender shall claim the inability to make or maintain Eurodollar Borrowings pursuant to Section 4.1 above, if any Lender is owed increased costs under Section 4.5 above, if any payment to any Lender by the Borrower is subject to any withholding tax pursuant to Section 4.6 above, or if any Lender is owed any cost or expense pursuant to Section 4.7 above, the Borrower shall have the right, if no Event of Default or Default then exists, to replace such Lender with another bank or financial institution provided that (i) if it is not a Lender or an Affiliate thereof, such bank or financial institution shall be reasonably acceptable to the Administrative Agent and (ii) such bank or financial institution shall unconditionally purchase, in accordance with Section 10.10 hereof, all of such Lender’s rights and obligations under this Agreement and the other Loan Documents and the appropriate pro rata share of such Lender’s Loans and Commitments, without recourse or expense to, or warranty by, such Lender being replaced for a purchase price equal to the aggregate outstanding principal amount of the Loans payable to such Lender, plus any accrued but unpaid interest on such Loans, plus accrued but unpaid fees in respect of such Lender’s Borrowings and Percentage of the Commitments hereunder to the date of such purchase on a date therein specified. The Borrower shall be obligated to pay, simultaneously with such purchase and sale, the increased costs, amounts, expenses and taxes under Sections 4.1, 4.5, 4.6, and 4.7 above, any amounts payable under Section 4.4 and all other costs, fees and expenses payable to such Lender hereunder and under the Loan Documents, to the date of such purchase as well as all other Obligations due and payable to or for the benefit of such Lender; provided, that if such bank or financial institution fails to purchase such rights and obligations, the Borrower shall continue to be obligated to pay the increased costs, amounts, expenses and taxes under Sections 4.1, 4.5, 4.6, and 4.7 above to such Lender.

SECTION 4.11 Maximum Interest. It is the intention of the parties hereto to conform strictly to applicable usury laws and, anything herein to the contrary notwithstanding, the obligations of the Borrower to the Administrative Agent and each Lender under this Agreement shall be subject to the limitation that payments of interest shall not be required to the extent that receipt thereof would be contrary to provisions of law applicable to the Administrative Agent or such Lender limiting rates of interest which may be charged or collected by the Administrative Agent or such Lender. Accordingly, if the transactions contemplated hereby would be usurious under applicable law (including the Federal and state laws of the United States of America, or of any other jurisdiction whose laws may be mandatorily applicable) with respect to the Administrative Agent or a Lender then, in that event, notwithstanding anything to the contrary in this Agreement, it is agreed as follows: (a) the provisions of this Section shall govern and control; (b) the aggregate of all consideration which constitutes interest under applicable law that is contracted for, charged or received under this Agreement, or under any of the other aforesaid

agreements or otherwise in connection with this Agreement by the Administrative Agent or such Lender shall under no circumstances exceed the maximum amount of interest allowed by applicable law (such maximum lawful interest rate, if any, with respect to such Lender herein called the “Highest Lawful Rate”), and any excess shall be credited to the Borrower by the Administrative Agent or such Lender (or, if such consideration shall have been paid in full, such excess refunded to the Borrower); (c) all sums paid, or agreed to be paid, to the Administrative Agent or such Lender for the use, forbearance and detention of the Indebtedness of the Borrower to the Administrative Agent or such Lender hereunder shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of such Indebtedness until payment in full so that the actual rate of interest is uniform throughout the full term thereof; and (d) if at any time the interest provided pursuant to Section 4.1 together with any other fees payable pursuant to this Agreement and the other Loan Documents and deemed interest under applicable law, exceeds that amount which would have accrued at the Highest Lawful Rate, the amount of interest and any such fees to accrue to the Administrative Agent or such Lender pursuant to this Agreement shall be limited, notwithstanding anything to the contrary in this Agreement to that amount which would have accrued at the Highest Lawful Rate, but any subsequent reductions, as applicable, shall not reduce the interest to accrue to the Administrative Agent or such Lender pursuant to this Agreement below the Highest Lawful Rate until the total amount of interest accrued pursuant to this Agreement and such fees deemed to be interest equals the amount of interest which would have accrued to the Administrative Agent or such Lender if a varying rate per annum equal to the interest provided pursuant to Section 3.2 had at all times been in effect, plus the amount of fees which would have been received but for the effect of this Section. For purposes of Section 303.201 of the Texas Finance Code, as amended, to the extent, if any, applicable to the Administrative Agent or a Lender, the Borrower agrees that the Highest Lawful Rate shall be the “indicated (weekly) rate ceiling” as defined in said Section, provided that the Administrative Agent or such Lender may also rely, to the extent permitted by applicable laws, on alternative maximum rates of interest under other laws applicable to the Administrative Agent or such Lender if greater. Chapter 346 of the Texas Finance Code (which regulates certain revolving credit loan accounts and revolving tri-party accounts (formerly Tex. Rev. Civ. Stat. Xxx. Art. 0000, Xx. 15)) shall not apply to this Agreement or the other Loan Documents.

ARTICLE IX
THE AGENTS

SECTION 9.1 Actions. Each Lender hereby appoints (i) JPMCB as the Administrative Agent under this Agreement and each other Loan Document, (ii) WACHOVIA BANK, NATIONAL ASSOCIATION and THE ROYAL BANK OF SCOTLAND PLC, as Co-Syndication Agents under this Agreement and each other Loan Document, and (iii) DEUTSCHE BANK SECURITIES INC. and CITIBANK, N.A., as Co-Documentation Agents under this Agreement and each other Loan Document. Each Lender authorizes the Administrative Agent to act on behalf of such Lender under this Agreement and each other Loan Document and, in the absence of other written instructions from the Required Lenders received from time to time by the Administrative Agent (with respect to which the Administrative Agent agrees that it will comply, except as otherwise provided in this Section or as otherwise advised by counsel), to exercise such powers hereunder and thereunder as are specifically delegated to or required of the Administrative Agent by the terms hereof and thereof, together with such powers as may be reasonably incidental thereto. Each Lender acknowledges that none of the Co-Syndication Agents or the Co-Documentation Agents have any duties or obligations under this Agreement or any other Loan Document in connection with their capacity as either a Co-Syndication Agent or a Co-Documentation Agent, respectively. Each Lender hereby indemnifies (which indemnity shall survive any termination of this Agreement) each of the Agents, pro rata according to such Lender’s Percentage, WHETHER OR NOT RELATED TO ANY SINGULAR, JOINT OR CONCURRENT NEGLIGENCE OF THE AGENTS, from and against any and all liabilities, obligations, losses, damages, claims, costs or expenses of any kind or nature whatsoever which may at any time be imposed on, incurred by, or asserted against, any Agent in any way relating to or arising out of this Agreement and any other Loan Document, including reasonable attorneys’ fees, and as to which such Agent is not reimbursed by the Borrower; provided, however, that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, claims, costs or expenses which are determined by a court of competent jurisdiction in a final proceeding to have resulted solely from such Agent’s gross negligence or willful misconduct. None of the Agents shall be required to take any action hereunder or under any other Loan Document, or to prosecute or defend any suit in respect of this Agreement or any other Loan Document, unless it is indemnified hereunder to its satisfaction. If any indemnity in favor of any Agent shall be or become inadequate, in such Agent’s determination, as the case may be, such Agent may call for additional indemnification from the Lenders and cease to do the acts indemnified against hereunder until such additional indemnity is given. Notwithstanding any provision to the contrary contained elsewhere in this Agreement or in any other Loan Document, none of the Agents shall have any duties or responsibilities, except as expressly set forth herein, nor shall any of the Agents have or be deemed to have any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against any of the Agents.

SECTION 9.2 Funding Reliance, etc. Unless the Administrative Agent shall have been notified by telephone, confirmed in writing, by any Lender by 5:00 p.m., Central time, on the day prior to a Borrowing (except with respect to a Borrowing comprised of Base Rate Loans, in which case notice shall be given no later than 12:00 noon, Central time, on the date of the proposed Borrowing) that such Lender will not make available the amount which would

constitute its Percentage of such Borrowing on the date specified therefor, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent and, in reliance upon such assumption, make available to the Borrower a corresponding amount. If and to the extent that such Lender shall not have made such amount available to the Administrative Agent, such Lender and the Borrower severally agree to repay the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date the Administrative Agent made such amount available to the Borrower to the date such amount is repaid to the Administrative Agent, at the Federal Funds Rate.

SECTION 9.3 Exculpation. None of the Agents and their respective directors, officers, employees or agents shall be liable to any Lender for any action taken or omitted to be taken by it under this Agreement or any other Loan Document, or in connection herewith or therewith, except for its own willful misconduct or gross negligence, nor responsible for any recitals or warranties herein or therein, nor for the effectiveness, enforceability, validity or due execution of this Agreement or any other Loan Document, nor to make any inquiry respecting the performance by the Borrower of its obligations hereunder or under any other Loan Document. Any such inquiry which may be made by any Agent shall not obligate it to make any further inquiry or to take any action. Each of the Agents shall be entitled to rely upon advice of counsel concerning legal matters and upon any notice, consent, certificate, statement or writing which such Agent believes to be genuine and to have been presented by a proper Person.

SECTION 9.4 Successor. Any of the Agents may resign as such at any time upon at least 30 days’ prior notice to the Borrower and all Lenders. If the Administrative Agent at any time shall resign, the Required Lenders may appoint another Lender as the successor Administrative Agent which shall thereupon become the Administrative Agent hereunder. If no successor Administrative Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving notice of resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be one of the Lenders or a commercial banking institution organized under the laws of the U.S. (or any State thereof) or a U.S. branch or agency of a commercial banking institution, and having a combined capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as the Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall be entitled to receive from the retiring Administrative Agent such documents of transfer and assignment as such successor Administrative Agent may reasonably request, and shall thereupon succeed to and become vested with all rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement. After a retiring Administrative Agent’s resignation hereunder as a Administrative Agent, the provisions of this Article IX shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Administrative Agent under this Agreement, and Section 10.4 (and, with respect to the Administrative Agent, Section 10.3) shall continue to inure to its benefit.

SECTION 9.5 Loans by the Agents. Each of the Agents shall have the same rights and powers with respect to the Loans made by it or any of its Affiliates and may exercise the same as if it were not a Agent. Each of the Agents and its Affiliates may accept deposits from,

lend money to, and generally engage in any kind of business with the Borrower or any Subsidiary or Affiliate of the Borrower as if it were not a Agent hereunder.

SECTION 9.6 Credit Decisions. Each Lender acknowledges that it has made its own credit decision to extend its Commitments hereunder (i) independently of each of the Agents and each other Lender, and (ii) based on such Lender’s review of the financial information of the Borrower, this Agreement, the other Loan Documents (the terms and provisions of which being satisfactory to such Lender) and such other documents, information and investigations as such Lender has deemed appropriate. Each Lender also acknowledges that it will continue to make its own credit decisions as to exercising or not exercising from time to time any rights and privileges available to it under this Agreement or any other Loan Document (i) independently of each of the Agents and each other Lender, and (ii) based on such other documents, information and investigations as it shall deem appropriate at any time.

SECTION 9.7 Copies, etc. The Administrative Agent shall give prompt notice to each Lender of each notice or request required or permitted to be given to the Administrative Agent by the Borrower pursuant to the terms of this Agreement (unless concurrently delivered to the Lenders by the Borrower). The Administrative Agent will distribute to each Lender each document or instrument received for its account and copies of all other communications received by the Administrative Agent from the Borrower for distribution to the Lenders by the Administrative Agent in accordance with the terms of this Agreement.

No failure or delay on the part of the Administrative Agent or any Lender in exercising any power or right under this Agreement or any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such power or right preclude any other or further exercise thereof or the exercise of any other power or right. No notice to or demand on the Borrower in any case shall entitle it

to any notice or demand in similar or other circumstances.

whether any such Indemnified Party is a party to the action for which indemnification hereunder is sought), whether brought by a third party or by the Borrower and regardless of whether any Indemnified Party is a party thereto, including reasonable attorneys’ fees and disbursements (collectively, the “Indemnified Liabilities”), incurred by the Indemnified Parties or any of them as a result of, or arising out of, or relating to any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of any Loan; the entering into and performance of this Agreement and any other Loan Document by any of the Indemnified Parties; any investigation, litigation or proceeding related to any acquisition or proposed acquisition by the Borrower or any of its Restricted Subsidiaries of all or any portion of the stock or assets of any Person, whether or not such Agent, the Arranger or such Lender is party thereto; any investigation, litigation or proceeding related to any environmental cleanup, audit, compliance or other matter relating to the protection of the environment or the Release by the Borrower or any of its Restricted Subsidiaries of any Hazardous Material; or the presence on or under, or the escape, seepage, leakage, spillage, discharge, emission, discharging or releases from, any real property owned or operated by the Borrower or any Subsidiary thereof of any Hazardous Material (including any losses, liabilities, damages, injuries, costs, expenses or claims asserted or arising under any Environmental Law), regardless of whether caused by, or within the control of, the Borrower or such Subsidiary; provided that such indemnity shall not, as to any Indemnified Party, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnified Party or (y) result from a claim brought by the Borrower or any Subsidiary against an Indemnified Party for breach in bad faith of such Indemnified Party’s obligations hereunder or under any other Loan Document, if the Borrower or such Subsidiary has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction.

The obligations of the Borrower under Sections 4.3, 4.4, 4.5, 4.6, 10.3 and 10.4, and the obligations of the Lenders under Section 9.1, shall in each case survive any termination of this Agreement, the payment in full of all Obligations and the termination of all Commitments.

Any provision of this Agreement or any other Loan Document which is prohibited or unenforceable in any jurisdiction shall, as to such provision and such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions of this Agreement or such Loan Document or affecting the validity or enforceability of such provision in any other jurisdiction.

SECTION 10.7 Headings. The various headings of this Agreement and of each other Loan Document are inserted for convenience only and shall not affect the meaning or interpretation of this Agreement or such other Loan Document or any provisions hereof or thereof.

SECTION 10.8 Governing Law; Entire Agreement. THIS AGREEMENT AND EACH OTHER LOAN DOCUMENT SHALL EACH BE DEEMED TO BE A

CONTRACT MADE UNDER AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF TEXAS, WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF LAWS. This Agreement and the other Loan Documents constitute the entire understanding among the parties hereto with respect to the subject matter hereof and supersede any prior agreements, written or oral, with respect thereto.

SECTION 10.9 Successors and Assigns. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns; provided, however, that: (a) the Borrower may not assign or transfer its rights or obligations hereunder without the prior written consent of the Administrative Agent and all Lenders; and (b) the rights of sale, assignment and transfer of the Lenders are subject to Section 10.10.

SECTION 10.10 Sale and Transfer of Loans and Commitments; Participations in Loans and Commitments. Each Lender may assign, or sell participations in, its Loans and Commitments to one or more other Persons in accordance with this Section.

SECTION 10.10.1 Assignments. Any Lender (a) with the written consent of the Borrower (provided that the consent of the Borrower shall not be required if an Event of Default has occurred and is continuing) and the Administrative Agent (which consent of the Borrower, if applicable, and the Administrative Agent shall not be unreasonably delayed or withheld), may at any time assign and delegate to one or more commercial banks or other financial institutions, and (b) with notice to the Borrower and the Administrative Agent, but without the consent of the Borrower or the Administrative Agent, may assign and delegate to any of its Affiliates or to any other Lender, Lender Affiliate or Approved Fund (each Person described in either of the foregoing clauses as being the Person to whom such assignment and delegation is to be made, being hereinafter referred to as an “Assignee Lender”), all or any fraction of such Lender’s total Loans and Commitments (which assignment and delegation shall be of a constant, and not a varying, percentage of all the assigning Lender’s Loans and Commitments and which shall be of equal pro rata shares of the Facility) in a minimum aggregate amount of $5,000,000 (or in a minimum amount of $1,000,000 in the case of an assignment to an Approved Fund with respect to which such Approved Fund plus the Lender or an Affiliate of such Lender who administers or manages such Approved Fund plus other Approved Funds administered or managed by the such Lender or an Affiliate of such Lender will then hold an amount of $5,000,000 or more); provided, however, that any such Assignee Lender will comply, if applicable, with the provisions contained in the last sentence of Section 4.6 and further, provided, however, that, the Borrower and the Administrative Agent shall be entitled to continue to deal solely and directly with such Lender in connection with the interests so assigned and delegated to an Assignee Lender until (i) written notice of such assignment and delegation, together with payment instructions, addresses and related information with respect to such Assignee Lender, shall have been given to the Borrower and the Administrative Agent by such Lender and such Assignee Lender, (ii) such Assignee Lender shall have executed and delivered to the Borrower and the Administrative Agent a Lender Assignment Agreement, accepted by the Administrative Agent, (iii) such Assignee Lender shall have delivered to the Administrative Agent an Administrative Questionnaire, and (iii) the processing fees described below shall have been paid. For the purposes of this Section 10.10.1, the term “Approved Fund” has the following meaning:

““Approved Fund” means any Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages a Lender.”

From and after the date that the Administrative Agent accepts such Lender Assignment Agreement, (x) the Assignee Lender thereunder shall be deemed automatically to have become a party hereto and to the extent that rights and obligations hereunder have been assigned and delegated to such Assignee Lender in connection with such Lender Assignment Agreement, shall have the rights and obligations of a Lender hereunder and under the other Loan Documents, and (y) the assignor Lender, to the extent that rights and obligations hereunder have been assigned and delegated by it in connection with such Lender Assignment Agreement, shall be released from its obligations hereunder and under the other Loan Documents. Accrued interest on that part of the predecessor Loans and Commitments, and accrued fees, shall be paid as provided in the Lender Assignment Agreement. Accrued interest on that part of the predecessor Loans and Commitments shall be paid to the assignor Lender. Accrued interest and accrued fees shall be paid at the same time or times provided in this Agreement. Such assignor Lender or such Assignee Lender must also pay a processing fee to the Administrative Agent upon delivery of any Lender Assignment Agreement in the amount of $3,500. Any attempted assignment and delegation not made in accordance with this Section shall be null and void.

SECTION 10.10.2 Participations. Any Lender may at any time sell to one or more commercial banks or other Persons (each of such commercial banks and other Persons being herein called a “Participant”) participating interests in any of the Loans, Commitments or other interests of such Lender hereunder; provided, however, that (a) no participation contemplated in this Section 10.10 shall relieve such Lender from its Commitments or its other obligations hereunder or under any other Loan Document, (b) such Lender shall remain solely responsible for the performance of its Commitments and such other obligations, (c) the Borrower and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and each of the other Loan Documents, (d) no Participant, unless such Participant is an Affiliate of such Lender, or is itself a Lender, shall be entitled to require such Lender to take or refrain from taking any action hereunder or under any other Loan Document, except that such Lender may agree with any Participant that such Lender will not, without such Participant’s consent, take any actions of the type described in clause (b) or (c) of Section 10.1, and (e) the Borrower shall not be required to pay any amount under Section 4.6 that is greater than the amount which it would have been required to pay had no participating interest been sold. The Borrower acknowledges and agrees that each Participant, for purposes of Sections 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9 and 10.4, shall be considered a Lender; provided that this sentence shall not obligate the Borrower to pay more under such Sections that it would be obligated to pay had no such participation been granted.

SECTION 10.10.3 Pledge by Lender. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any

of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

SECTION 10.11 Other Transactions. Nothing contained herein shall preclude the Administrative Agent or any other Lender from engaging in any transaction, in addition to those contemplated by this Agreement or any other Loan Document, with the Borrower or any of its Affiliates in which the Borrower or such Affiliate is not restricted hereby from engaging with any other Person.

SECTION 10.12 Confidentiality. Each of the Agents and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority or self-regulatory body, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, 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 hedging agreement, (g) with the consent of Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section by any Person or (ii) becomes available to any Agent or any Lender on a nonconfidential basis from a source other than Borrower or any of its Affiliates. For the purposes of this Section, “Information” means all information received from Borrower or its Affiliate relating to Borrower and its Subsidiaries or their business, other than any such information that is available to any Agent or any Lender on a nonconfidential basis prior to disclosure by Borrower or any of its Affiliates. 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 Forum Selection and Consent to Jurisdiction. ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF THE ADMINISTRATIVE AGENT, THE LENDERS OR THE BORROWER SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS OF THE STATE OF TEXAS OR NEW YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF TEXAS OR THE SOUTHERN DISTRICT OF NEW YORK; PROVIDED, HOWEVER, THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT THE ADMINISTRATIVE AGENT’S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH COLLATERAL OR OTHER PROPERTY MAY BE FOUND. THE BORROWER, THE ADMINISTRATIVE AGENT,

AND EACH LENDER HEREBY EXPRESSLY AND IRREVOCABLY SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF TEXAS OR NEW YORK AND OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF TEXAS OR THE SOUTHERN DISTRICT OF NEW YORK FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE AND IRREVOCABLY AGREE TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH SUCH LITIGATION. THE BORROWER, THE ADMINISTRATIVE AGENT, AND EACH LENDER FURTHER IRREVOCABLY CONSENT TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF TEXAS. THE BORROWER, THE ADMINISTRATIVE AGENT, AND EACH LENDER HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY HAVE OR HEREAFTER MAY HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. TO THE EXTENT THAT THE BORROWER HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT OF FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, THE BORROWER HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

SECTION 10.14 Waiver of Jury Trial. THE ADMINISTRATIVE AGENT, THE LENDERS AND THE BORROWER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF THE ADMINISTRATIVE AGENT, THE LENDERS OR THE BORROWER. THE BORROWER ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT CONSIDERATION FOR THIS PROVISION (AND EACH OTHER PROVISION OF EACH OTHER LOAN DOCUMENT TO WHICH IT IS A PARTY) AND THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE ADMINISTRATIVE AGENT AND THE LENDERS ENTERING INTO THIS AGREEMENT AND EACH SUCH OTHER LOAN DOCUMENT.

SECTION 10.15 USA Patriot Act Notice. Each Lender and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the USA Patriot Act.

OPINION OF COUNSEL TO THE BORROWER

April 4, 2005

The Lenders and the Agents Party to the Credit Agreement
c/o JPMorgan Chase Bank, N.A.,
as Administrative Agent for the Lenders
0000 Xxxxxx Xxxxxx, 00^xx Xxxxx
Xxxxxxx, Xxxxx 00000

Ladies and Gentlemen:

We have acted as counsel to Noble Energy, Inc., a Delaware corporation (“Borrower”), in connection with the $1,300,000,000 Credit Agreement dated as of April 4, 2005 (the “Agreement”) among Borrower, JPMorgan Chase Bank, N.A., individually and as administrative agent for the Lenders (“Agent”), certain Co-Documentation Agents, certain Co-Syndication Agents, and Lenders named therein. This opinion letter is delivered to you pursuant to Section 5.1.3 of the Agreement. Capitalized terms used but not otherwise defined herein shall have the meanings given to them in the Agreement.

In our capacity as counsel for Borrower, we have examined executed originals or telecopies of executed originals of the Agreement and the other Loan Documents that have been executed and delivered to you by Borrower today in connection with the Agreement. We have also examined and relied upon originals or copies, certified or otherwise authenticated to our satisfaction, of such corporate records of Borrower, certificates of officers of Borrower, certificates and letters of public officials, and other instruments and documents as we have deemed necessary to require as a basis for the opinions hereinafter expressed. In such examination, we have assumed the genuineness and authenticity of all documents submitted to us as originals (other than the Loan Documents), the conformity with genuine and authentic originals of all documents submitted to us as copies, and the genuineness of all signatures (other than the signatures on behalf of Borrower on the Loan Documents).

Where facts material to the opinions hereinafter expressed were not independently established by us, we have relied upon the representations and warranties made to you by Borrower in the Loan Documents and upon oral and written statements of and information furnished by officers of Borrower and its Subsidiaries, where we deemed such reliance appropriate under the circumstances. We have necessarily assumed the accuracy and completeness of such representations, warranties, statements and other information.

Based on the foregoing and on the assumptions hereinafter set forth, and subject to the exceptions, limitations and qualifications hereinafter expressed, it is our opinion that:

1. Borrower is a duly incorporated and validly existing corporation in good standing under the laws of the State of Delaware and has the corporate power and

authority to own its property and assets and to transact the business in which it is engaged. Borrower is duly qualified and is authorized to do business and is in good standing as a foreign corporation in the State of Texas. Borrower has the corporate power to execute, deliver and carry out the terms and provisions of each of the Loan Documents to which it is a party and has taken all necessary corporate action to authorize the execution, delivery and performance by it of each of such Loan Documents.

2. The execution, delivery and performance by Borrower of the Agreement and each other Loan Document executed by it are within its corporate powers, have been duly authorized by all necessary corporate action, and do not (i) violate the certificate of incorporation or by-laws of Borrower, (ii) violate, constitute a breach of or result in the imposition or creation of (or the obligation to impose or create) a Lien pursuant to, any of the terms or provisions of any indenture, loan agreement or other agreement to which Borrower is a party or by which Borrower or its property is bound that is filed as (or incorporated by reference as) an exhibit to Borrower’s Annual Report on Form 10-K for the fiscal year ended December 31, 2004, (iii) violate any applicable statute, rule or regulation of any governmental body of the United States of America or the State of Texas, or (iv) to the knowledge of the undersigned, any court decree or order binding upon Borrower.

3. No authorization or approval or other action by, and no notice to or filing with, any governmental authority or regulatory body pursuant to any law or any rule or order of general application is required for the due execution, delivery or performance by Borrower of any Loan Document to which it is a party.

4. Neither Borrower nor any of its Subsidiaries is an “investment company” within the meaning of the Investment Company Act of 1940, as amended, or a “holding company,” or a “subsidiary company” of a “holding company,” or an “affiliate” of a “holding company” or of a “subsidiary company” of a “holding company,” within the meaning of the Public Utility Holding Company Act of 1935, as amended.

5. Each of the Loan Documents to which Borrower is a party has been duly executed and delivered by Borrower. The Loan Documents constitute the legal, valid and binding obligations of Borrower enforceable in accordance with their respective terms, except as enforcement thereof may be limited by applicable bankruptcy, insolvency, reorganization or other similar laws affecting creditors’ rights generally and equitable principles of general applicability.

6. To the knowledge of the undersigned, there is no pending or threatened litigation, action, proceeding, or labor controversy affecting Borrower or any of its Subsidiaries, properties, businesses, assets or revenues, which purports to affect the legality, validity or enforceability of, or the rights and remedies of Agent and the Lenders under, the Agreement or any other Loan Document.

The opinions expressed above are based in part upon the assumptions, and are subject to the exceptions, limitations and qualifications, set forth below:

(a) Whenever any opinion expressed herein with respect to any matter is qualified by the phrase “to the knowledge of the undersigned,” such phrase (A) indicates that (i) no information has come to the attention of any attorney of this firm who has devoted substantive attention to the transactions contemplated in the Agreement that has given any such person actual knowledge concerning such matter different from that expressed in such opinion; (ii) except as otherwise stated herein, we have not undertaken any independent investigation with respect to such matter but have relied on representations made by Borrower in the Loan Documents and on information otherwise provided to us by it; and (iii) no inference that any such person has actual knowledge concerning such matters should be drawn from the fact of our representation of Borrower and its Subsidiaries or our expression of such opinion; and (B) does not encompass the actual knowledge of any attorney of this firm who obtained such knowledge in his capacity as a director of Borrower.

(b) Except as expressly set forth herein, we have made no independent investigation as to the accuracy or completeness of any representation, warranty, data or other information, written or oral, made or furnished in or in connection with the Loan Documents, or otherwise.

(c) We do not purport to be experts as to the laws of any jurisdiction other than the State of Texas and the United States of America, and we express no opinion herein with respect to the laws of any such other jurisdiction, except insofar as the matters covered by the foregoing opinions may involve or be governed by or construed under the General Corporation Law of the State of Delaware. Our opinion regarding the General Corporation Law of the State of Delaware is confined to our reading thereof without application of judicial or administration interpretations thereof.

(d) In rendering certain of the opinions expressed above, we have assumed that each of the Agents and Lenders (i) are duly authorized to execute and deliver (or accept), and have duly executed and delivered (or accepted), the Loan Documents required to be executed and delivered (or accepted) by it and (ii) each Lender will fund the Loans to the extent required to be funded by it under the Agreement.

(e) We express no opinion concerning (i) any right of any Agent or any Lender or any other person to be indemnified against (or released from the consequences of) its own negligence or willful misconduct; (ii) the enforceability of any obligations of any party other than Borrower; (iii) the effectiveness or enforceability of provisions restricting access to courts or to legal or equitable remedies or purporting to affect jurisdiction or venue; or (iv) the effectiveness or enforceability of any waiver of the right to trial by jury or any rights or benefits that cannot be waived under applicable law.

(f) For purposes of this opinion, we have assumed that the Borrower is, and in connection with each incurrence of Indebtedness under the Agreement will be, in compliance with the covenants contained in Sections 7.2.3(a) and (b) of (i) the Agreement, (ii) the $400,000,000 Credit Agreement dated as of November 30, 2001, as amended, among Borrower (formerly known as Noble Affiliates, Inc.), JPMorgan Chase Bank as Administrative Agent, and the Co-Documentation Agents, Syndication Agent

and Lenders referred to therein, and (iii) the $400,000,000 Credit Agreement dated as of October 28, 2004, as amended, among Borrower, JPMorgan Chase Bank as Administrative Agent, and the Co-Documentation Agents, Syndication Agent and Lenders referred to therein; and contained in Sections 7.2.3(a) and (b) of: (i) the Term Loan Agreement dated as of January 30, 2004, among Noble Energy Mediterranean Ltd., Sumitomo Mitsui Banking Corporation as Initial Lender and as Agent for the Lenders, (ii) the Term Loan Agreement dated as of February 2, 2004, among Noble Energy Mediterranean Ltd., Bank One, NA as Agent for the Lenders and certain commercial lending institutions, and (iii) the Term Loan Agreement dated as of February 4, 2004, among Noble Energy Mediterranean Ltd., the Royal Bank of Scotland Finance (Ireland) as Agent for the Lenders and as the initial Lender, each of which Sections 7.2.3(a) and (b) are worded identically to Sections 7.2.3(a) and (b) of the Agreement.

This opinion letter is to be limited in its use to reliance by you and your counsel in consummating the Agreement. No other person or entity (other than the Lenders and the Assignee Lenders or their counsel) may rely or claim reliance on any opinion expressed herein except with our express written consent. We assume no obligation to supplement this opinion if, after the date hereof, any applicable law changes or we become aware of any facts that might change the opinions set forth herein.

Respectfully submitted,
