“Accounting Changes” is defined in Section 9.8 hereof.

“Acquisition” means any transaction, or any series of related transactions, consummated on or after the Closing Date, by which the Borrower or any of its Subsidiaries (i) acquires any going business or all or substantially all of the assets of any firm, corporation or limited liability company, or division thereof, whether through purchase of assets, merger or otherwise or (ii) directly or indirectly acquires (in one transaction or as the most recent transaction in a series of transactions) at least a majority (in number of votes) of the securities of a corporation which have ordinary voting power for the election of directors (other than securities having such power only by reason of the happening of a contingency) or a majority (by percentage of voting power) of the outstanding ownership interests of a partnership or limited liability company of any Person.

“Administrative Questionnaire” means an Administrative Questionnaire in a form supplied by the Agent.

“Advance” means Loans (i) made by the Lenders on the Closing Date or (ii) converted or continued by the Lenders on the same date of conversion or continuation, consisting, in either case, of the aggregate amount of the several Loans of the same Type and, in the case of Eurodollar Loans, for the same Interest Period.

“Affiliate” of any Person means any other Person directly or indirectly controlling, controlled by or under common control with such Person. A Person shall be deemed to control another Person if the controlling Person is the “beneficial owner” (as defined in Rule 13d-3 under the Securities Exchange Act of 1934) of 10% or more of any class of voting securities (or other ownership interests) of the controlled Person or possesses, directly or indirectly, the power to direct or cause the direction of the management or policies of the controlled Person, whether through ownership of voting securities, by contract or otherwise.

“Agent” means JPMCB, not in its individual capacity as a Lender, but in its capacity as contractual representative of the Lenders pursuant to Article X, and any successor Agent appointed pursuant to Article X.

“Agreement” means this Credit Agreement, as it may be amended, restated, supplemented or otherwise modified and as in effect from time to time.

“Agreement Accounting Principles” means generally accepted accounting principles as in effect in the United States from time to time, applied in a manner consistent with that used in preparing the financial statements referred to in Section 5.4; provided, however, that except as provided in Section 9.8, with respect to the calculation of the financial ratio set forth in Section 6.17 (and the defined terms used in such Section), “Agreement Accounting Principles” means generally accepted accounting principles as in effect in the United States as of the Closing Date of the Existing Credit Agreement, applied in a manner consistent with that used in preparing the financial statements referred to in Section 5.4 hereof.

“Applicable Index” means, as of any date of determination, the average, as determined by the Agent, of the Applicable Quote for each day during the preceding 30 days on which the Applicable Quote was available.

“Applicable Margin” means, with respect to each Eurodollar Advance, the Applicable Index as determined as of the first Business Day following delivery of the Borrowing Notice or Continuation/Conversion Notice in respect of such Advance, provided that (a) if on such date of determination the Applicable Index is less than 0.90% per annum, the Applicable Margin in respect of such Advance shall be 0.90% per annum, and (b) if on such date of determination the Applicable Index is greater than 1.50% per annum, the Applicable Margin in respect of such Advance shall be 1.50% per annum.

If at any time the Applicable Quote shall have been unavailable for the last 3 consecutive Business Days, then the Borrower and the Lenders shall negotiate in good faith while the Applicable Quote shall remain unavailable for a period of up to thirty days after such third Business Day (the “Negotiating Period”) to agree on an alternative method for establishing the Applicable Margin. Each Eurodollar Advance that commences during the Negotiating Period will have an Interest Period of one month and the Applicable Margin applicable thereto shall be the Applicable Index as determined (in accordance with the definition of “Applicable Index”) as of the last Business Day on which the Applicable Quote shall have been available. In the event that an amendment hereof executed by the Borrower and each Lender and specifying an alternative method for establishing the Applicable Margin shall not have been delivered to the Agent on or prior to the last day of the Negotiating Period, then until such an Agreement is delivered to the Agent all Advances commencing thereafter shall be Floating Rate Advances. If at any time after the commencement of a Negotiating Period the Applicable Quote shall have been available on not less than five (5) consecutive Business Days, the Applicable Margin shall be determined based the Applicable Quote. For the avoidance of doubt, neither the Interest Period nor the Eurodollar Rate applicable to any Eurodollar Advance that is outstanding when a Negotiating Period begins will change as a result of the commencement of such Negotiating Period.

“Applicable Quote” means, as of any date, the Comp Spread for the Markit CDX.NA.IG Series 10 (5 Year Period) as of the close of business, New York City time, on the Business Day immediately preceding such date, as determined by the Agent, provided that following each rollover to a successor series, the “Applicable Quote” shall mean, as of any date thereafter, the Comp Spread for the 5 Year Period under such successor series as of such time on such date. For the avoidance of doubt, following each rollover to a successor series the prior series’ Applicable Quotes will be used on any date on which the Applicable Index is determined for

each of the preceding 30 days for which such successor series was not in effect until such time as such successor series has been in effect for 30 days.

During the continuance of a Default, the Required Lenders may, at their option, by notice to the Borrower (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 8.2 requiring unanimous consent of the Lenders to changes in interest rates), declare that (i) each Eurodollar Advance shall bear interest for the remainder of the applicable Interest Period at the rate otherwise applicable during such Interest Period plus 2% per annum and (ii) each Floating Rate Advance shall bear interest at a rate per annum equal to the Floating Rate in effect from time to time plus 2% per annum, provided that, during the continuance of a Default under Section 7.6 or 7.7, the interest rates set forth in clauses (i) and (ii) above shall be applicable to all Advances, fees and other Obligations of the Borrower hereunder without any election or action on the part of the Agent or any Lender.

2.15. Funding of Loans; Method of Payment. All payments of the Obligations hereunder shall be made, without setoff, deduction or counterclaim, in immediately available funds to the Agent at the Agent’s address specified pursuant to Article XIII, or at any other Lending Installation of the Agent specified in writing by the Agent, by 12:00 noon (New York time) on the date when due and shall be applied ratably by the Agent among the Lenders. Each payment delivered to the Agent for the account of any Lender shall be delivered promptly by the Agent to such Lender in the same type of funds that the Agent received at its address specified pursuant to Article XIII or at any Lending Installation specified in a notice received by the Agent from such Lender.

2.16. Noteless Agreement; Evidence of Indebtedness. (i) 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 to the Borrower from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(ii)

The Agent shall also maintain accounts in which it will record (a) the date and the amount of each Loan made to the Borrower hereunder, the Type thereof and the Interest Period (in the case of a Eurodollar Advance) with respect thereto, (b) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder, (c) the effective date and amount of each Assignment Agreement delivered to and accepted by it pursuant to Section 12.3 and the parties thereto, (d) the amount of any sum received by the Agent hereunder from the Borrower and each Lender’s share thereof, and (e) all other appropriate debits and credits as provided in this Agreement, including, without limitation, all fees, charges, expenses and interest.

(iii)

The entries maintained in the accounts maintained pursuant to paragraphs (i) and (ii) above shall be prima facie evidence absent manifest error of the existence and amounts of the Obligations therein recorded; provided, however, that the failure of the Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms.

(iv)

Any Lender may request that its Loans be evidenced by a promissory note in substantially the form of Exhibit E (a “Note”). In such event, the Borrower shall prepare, execute and deliver to such Lender such Note payable to the order of such Lender. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (prior to any assignment pursuant to Section 12.3) be represented by one or more Notes payable to the order of the payee named therein, except to the extent that any such Lender subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described in paragraphs (i) and (ii) above.

2.17. Telephonic Notices. The Borrower hereby authorizes the Lenders and the Agent to extend, convert or continue Advances, effect selections of Types of Advances and to transfer funds based on telephonic notices made by any person or persons the Agent or any Lender in

good faith believes to be acting on behalf of the Borrower, it being understood that the foregoing authorization is specifically intended to allow Borrowing Notices and Conversion/Continuation Notices to be given telephonically. The Borrower agrees to deliver promptly to the Agent a written confirmation, signed by an Authorized Officer, if such confirmation is requested by the Agent or any Lender, of each telephonic notice. If the written confirmation differs in any material respect from the action taken by the Agent and the Lenders, the records of the Agent and the Lenders shall govern absent manifest error.

2.18. Interest Payment Dates; Interest Basis. Interest accrued on each Floating Rate Advance shall be payable in arrears on each Payment Date, commencing with the first such date to occur after the Closing Date, on any date on which such Floating Rate Advance is prepaid, whether due to acceleration or otherwise, and at maturity. Interest accrued on that portion of the outstanding principal amount of any Floating Rate Advance converted into a Eurodollar Advance on a day other than a Payment Date shall be payable on the date of conversion. Interest accrued on each Eurodollar Advance shall be payable on the last day of each applicable Interest Period, on any date on which the Eurodollar Advance is prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued on each Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such Interest Period. Interest accrued on any Advance that is not paid when due shall be payable on demand and on the date of payment in full. Interest on Eurodollar Advances hereunder shall be calculated for actual days elapsed on the basis of a 360-day year. Interest on Floating Rate Advances shall be calculated for actual days elapsed on the basis of a 365/366-day year. Interest shall be payable for the day an Advance is made but not for the day of any payment on the amount paid if payment is received prior to 12:00 noon (New York time) at the place of payment. If any payment of principal of or interest on an Advance or any other amounts payable to the Agent or any Lender hereunder shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of principal payment, such extension of time shall be included in computing interest and commissions in connection with such payment.

2.19. Notification of Advances, Interest Rates, Prepayments and Commitment Reductions; Availability of Loans. Promptly after receipt thereof, the Agent will notify each Lender in writing of the contents of each Commitment reduction notice, Borrowing Notice, Conversion/Continuation Notice, and repayment notice received by it hereunder. The Agent will notify the Borrower and each Lender of the interest rate applicable to each Eurodollar Advance promptly upon determination of such interest rate and will give the Borrower and each Lender prompt notice of each change in the Floating Rate.

2.20. Lending Installations. Each Lender may book its Loans at any Lending Installation selected by such Lender and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Loans and any Notes issued hereunder shall be deemed held by each Lender for the benefit of any such Lending Installation. Each Lender may, by written notice to the Agent and the Borrower in accordance with Article XIII, designate replacement or additional Lending Installations through which Loans will be made by it and for whose account Loan payments are to be made.

2.21. Non-Receipt of Funds by the Agent. Unless the Borrower or a Lender, as the case may be, notifies the Agent prior to the date (or, in the case of a Lender with respect to a Floating Rate Advance under Section 2.11, prior to the time) on which it is scheduled to make payment to the Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal or interest to the Agent for the account of the Lenders, that it does not intend to make such payment, the Agent may assume that such payment has been made. The Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If such Lender or the Borrower, as the case may be, has not in fact made such payment to the Agent, the recipient of such payment shall, on demand by the Agent, repay to the Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate per annum equal to (x) in the case of payment by a Lender, the Federal Funds Effective Rate for such day for the first three days and, thereafter, the interest rate applicable to the relevant Loan or (y) in the case of payment by the Borrower, the interest rate applicable to the relevant Loan.

2.22. Replacement of Lender. If the Borrower is required pursuant to Section 3.1, 3.2 or 3.5 to make any additional payment to any Lender or if any Lender’s obligation to make or continue, or to convert Floating Rate Advances into, Eurodollar Advances shall be suspended pursuant to Section 3.3 (any Lender so affected an “Affected Lender”), the Borrower may elect, if such amounts continue to be charged or such suspension is still effective, to require such Affected Lender to assign its Loans, provided that no Default or Unmatured Default shall have occurred and be continuing at the time of such assignment, and provided further that, concurrently with such assignment, (i) another bank or other entity which is reasonably satisfactory to the Borrower and the Agent shall agree, as of date of such assignment, to purchase for cash at face amount the Loans of the Affected Lender pursuant to an Assignment Agreement substantially in the form of Exhibit C and to become a Lender for all purposes under this Agreement and to assume all obligations of the Affected Lender and to comply with the requirements of Section 12.3 applicable to assignments, and (ii) the Borrower shall pay to such Affected Lender in immediately available funds on the day of such assignment (A) all interest and other amounts then accrued but unpaid to such Affected Lender by the Borrower hereunder to and including the date of assignment, including without limitation payments due to such Affected Lender under Sections 3.1, 3.2 and 3.5, and (B) an amount, if any, equal to the payment which would have been due to such Lender on the day of such assignment under Section 3.4 had the Loans of such Affected Lender been prepaid on such date rather than sold to the assignee Lender, in each case to the extent not paid by the purchasing lender.

ARTICLE III

YIELD PROTECTION; TAXES

3.1. Yield Protection. If, on or after the Closing Date, the adoption of any law or any governmental or quasi-governmental rule, regulation, policy, guideline or directive (whether or not having the force of law), or any change in any such law, rule, regulation, policy, guideline or directive or in the interpretation or administration thereof by any governmental or quasi-

governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender or applicable Lending Installation with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency:

3.1.1 subjects any Lender or any applicable Lending Installation to any Taxes, or changes the basis of taxation of payments (other than with respect to Excluded Taxes) to any Lender in respect of its Eurodollar Loans, or

3.1.2 imposes or increases or deems applicable any reserve, assessment, insurance charge, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or any applicable Lending Installation (other than reserves and assessments taken into account in determining the interest rate applicable to Eurodollar Advances), or

3.1.3 imposes any other condition the result of which is to increase the cost to any Lender or any applicable Lending Installation of making, funding or maintaining its Commitment or Eurodollar Loans or reduces any amount receivable by any Lender or any applicable Lending Installation in connection with its Commitment or Eurodollar Loans, or requires any Lender or any applicable Lending Installation to make any payment calculated by reference to the amount of Commitment or Eurodollar Loans held or interest received by it, by an amount deemed material by such Lender,and the result of any of the foregoing is to increase the cost to such Lender or applicable Lending Installation of making or maintaining its Commitment or Eurodollar Loans or to reduce the return received by such Lender or applicable Lending Installation in connection with such Commitment or Eurodollar Loans, then, within 15 days of demand, accompanied by the written statement required by Section 3.6, by such Lender, the Borrower shall pay such Lender such additional amount or amounts as will compensate such Lender for such increased cost or reduction in amount received.

3.2. Changes in Capital Adequacy Regulations. If a Lender determines the amount of capital required or expected to be maintained by such Lender, any Lending Installation of such Lender or any corporation controlling such Lender is increased as a result of a Change, then, within 15 days of demand, accompanied by the written statement required by Section 3.6, by such Lender, the Borrower shall pay such Lender the amount necessary to compensate for any shortfall in the rate of return on the portion of such increased capital which such Lender determines is attributable to this Agreement, its Loans or its Commitment hereunder (after taking into account such Lender’s policies as to capital adequacy). “Change” means (i) any change after the Closing Date in the Risk-Based Capital Guidelines or (ii) any adoption of, or change in, or change in the interpretation or administration of any other law, governmental or quasi-governmental rule, regulation, policy, guideline, interpretation, or directive (whether or not having the force of law) after the Closing Date which affects the amount of capital required or expected to be maintained by any Lender or any Lending Installation or any corporation

controlling any Lender. “Risk-Based Capital Guidelines” means (i) the risk-based capital guidelines in effect in the United States on the Closing Date, including transition rules, and (ii) the corresponding capital regulations promulgated by regulatory authorities outside the United States implementing the July 1988 report of the Basle Committee on Banking Regulation and Supervisory Practices Entitled “International Convergence of Capital Measurements and Capital Standards,” including transition rules, and any amendments to such regulations adopted prior to the Closing Date.

3.3. Availability of Types of Advances. If (x) any Lender determines that maintenance of its Eurodollar Loans at a suitable Lending Installation would violate any applicable law, rule, regulation, or directive, whether or not having the force of law, or (y) the Required Lenders determine that (i) deposits of a type and maturity appropriate to match fund Eurodollar Advances are not available or (ii) the interest rate applicable to Eurodollar Advances does not accurately reflect the cost of making or maintaining Eurodollar Advances, or (iii) no reasonable basis exists for determining the Eurodollar Base Rate, then the Agent shall suspend the availability of Eurodollar Advances and require any affected Eurodollar Advances to be repaid or converted to Floating Rate Advances on the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by law, subject to the payment of any funding indemnification amounts required by Section 3.4.

3.4. Funding Indemnification. If any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, or a Eurodollar Advance is not made or continued or a Floating Rate Advance is not converted into a Eurodollar Advance on the date specified by the Borrower for any reason other than default by the Lenders, or a Eurodollar Advance is not prepaid on the date specified by the Borrower for any reason, the Borrower will indemnify each Lender for any loss or cost incurred by it resulting therefrom, including, without limitation, any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance.

3.5. Taxes.

(i)

All payments by the Borrower to or for the account of any Lender or the Agent hereunder or under any Note shall be made free and clear of and without deduction for any and all Taxes. If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder by the Borrower to any Lender or the Agent, (a) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 3.5) such Lender or the Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (b) the Borrower shall make such deductions, (c) the Borrower shall pay the full amount deducted to the relevant authority in accordance with applicable law and (d) the Borrower shall furnish to the Agent the original copy of a receipt evidencing payment thereof or, if a receipt cannot be obtained with reasonable efforts, such other evidence of payment as is reasonably acceptable to the Agent, in each case within 30 days after such payment is made.

(ii)

In addition, the Borrower agrees to pay any present or future stamp or documentary taxes and any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under any Note or from the execution or delivery of, or otherwise with respect to, this Agreement or any Note (“Other Taxes”).

(iii)

The Borrower shall indemnify the Agent and each Lender for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed on amounts payable under this Section 3.5) paid by the Agent or such Lender and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. Payments due under this indemnification shall be made within 30 days of the date the Agent or such Lender makes demand therefor pursuant to Section 3.6.

(iv)

Each Lender that is not incorporated under the laws of the United States of America or a state thereof (each a “Non-U.S. Lender”) agrees that it will, not more than ten Business Days after the date on which it becomes a party to this Agreement (but in any event before a payment is due to it hereunder), (i) deliver to the Borrower and the Agent two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI, certifying in either case that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, or (ii) in the case of a Non-U.S. Lender that is fiscally transparent, deliver to the Agent a United States Internal Revenue Form W-8IMY together with the applicable accompanying forms, W-8 or W-9, as the case may be, and certify that it is entitled to an exemption from United States withholding tax. Each Non-U.S. Lender further undertakes to deliver to the Borrower and the Agent (x) renewals or additional copies of such form (or any successor form) on or before the date that such form expires or becomes obsolete, and (y) after the occurrence of any event requiring a change in the most recent forms so delivered by it, such additional forms or amendments thereto as may be reasonably requested by the Borrower or the Agent. All forms or amendments described in the preceding sentence shall certify that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form or amendment with respect to it and such Lender advises the Borrower and the Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax.

(v)

For any period during which a Non-U.S. Lender has failed to provide the Borrower with an appropriate form pursuant to clause (iv) above (unless such failure is due to a change in treaty, law or regulation, or any change in the interpretation or administration thereof by any governmental authority, occurring subsequent to the date on which such Non-U.S. Lender became a party to this

Agreement (or, in the case of Non-U.S. Lender that becomes a Lender pursuant to an assignment, unless and to the extent the assigning Lender was entitled, at the time of the assignment, to receive additional amounts with respect to such withholding taxes pursuant to this Section 3.5), such Non-U.S. Lender shall not be entitled to indemnification under this Section 3.5 with respect to Taxes imposed by the United States; provided that, should a Non-U.S. 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 under clause (iv) above, the Borrower shall take such steps as such Non-U.S. Lender shall reasonably request to assist such Non-U.S. Lender to recover such Taxes.

(vi)

Any Lender that is entitled to an exemption from or reduction of withholding tax with respect to payments under this Agreement or any Note pursuant to the law of any relevant jurisdiction or any treaty shall deliver to the Borrower (with a copy to the Agent), at the time or times prescribed by applicable law, 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.

(vii)

If the U.S. Internal Revenue Service or any other governmental authority of the United States or any other country or any political subdivision thereof asserts a claim that the Agent did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered or properly completed, because such Lender failed to notify the Agent of a change in circumstances which rendered its exemption from withholding ineffective, or for any other reason), such Lender shall indemnify the Agent fully for all amounts paid, directly or indirectly, by the Agent as tax, withholding therefor, or otherwise, including penalties and interest, and including taxes imposed by any jurisdiction on amounts payable to the Agent under this subsection, together with all reasonable costs and expenses related thereto (including attorneys’ fees and time charges of attorneys for the Agent, which attorneys may be employees of the Agent). The obligations of the Lenders under this Section 3.5(vii) shall survive the payment of the Obligations and termination of this Agreement.

3.6. Lender Statements; Survival of Indemnity. Each Lender shall deliver a written statement of such Lender to the Borrower (with a copy to the Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth in reasonable detail the calculations upon which such Lender determined such amount and shall be final, conclusive and binding on the Borrower in the absence of manifest error, and upon reasonable request of the Borrower, such Lender shall promptly provide supporting documentation describing and/or evidence of the applicable event giving rise to such amount to the extent not inconsistent with such Lender’s policies or applicable law. Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar Loan through the purchase of a deposit of the type, currency and maturity corresponding to the deposit used as a reference in determining the Eurodollar Rate applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in the written statement of any Lender shall be payable on demand after receipt by the Borrower of such written statement. The obligations of the Borrower under Sections 3.1, 3.2, 3.4

and 3.5 shall survive payment of the Obligations and termination of this Agreement. Notwithstanding the foregoing, the Borrower shall not be responsible for any reimbursement of any such amount which shall have accrued and of which the applicable Lender shall have become aware more than 180 days prior to its delivery to the Borrower of notice requesting reimbursement thereof.

3.7. Alternative Lending Installation. To the extent reasonably possible, each Lender shall designate an alternate Lending Installation with respect to its Eurodollar Loans to reduce any liability of the Borrower to such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of Eurodollar Advances under Section 3.3, so long as such designation is not, in the judgment of such Lender, disadvantageous to such Lender. A Lender’s designation of an alternative Lending Installation shall not affect the Borrower’s rights under Section 2.22 to replace a Lender.

ARTICLE V

REPRESENTATIONS AND WARRANTIES

The Borrower represents and warrants to each Lender and the Agent, as to the Borrower and its Subsidiaries, as of each of (i) the date hereof and (ii) the Closing Date:

5.1. Existence and Standing. The Borrower and each of its Subsidiaries (other than any Project Finance Subsidiary or Non-Material Subsidiary or an SPC) is a corporation, partnership (in the case of Subsidiaries only) or limited liability company duly and properly incorporated or organized, as the case may be, validly existing and (to the extent such concept applies to such entity) in good standing under the laws of its jurisdiction of incorporation or organization and has all requisite authority to conduct its business in each jurisdiction in which its business is conducted.

5.2. Authorization and Validity. The Borrower has the power and authority and legal right to execute and deliver the Loan Documents and to perform its obligations thereunder. The execution and delivery by the Borrower of the Loan Documents and the performance of its obligations thereunder have been duly authorized by proper proceedings, and the Loan Documents to which the Borrower is a party constitute legal, valid and binding obligations of the Borrower enforceable against the Borrower in accordance with their terms, except as enforceability may be limited by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization or similar laws relating to or affecting the enforcement of creditors’ rights generally; (ii) general equitable principles (whether considered in a proceeding in equity or at law) and (iii) requirements of reasonableness, good faith and fair dealing.

5.3. No Conflict; Government Consent. Neither the execution and delivery by the Borrower of the Loan Documents, nor the consummation of the transactions therein contemplated, nor compliance with the provisions thereof will violate (i) any law, rule, regulation, order, writ, judgment, injunction, decree or award binding on the Borrower or any of its Subsidiaries or (ii) the Borrower’s or any Subsidiary’s articles or certificate of incorporation, partnership agreement, certificate of partnership, articles or certificate of organization, by-laws, or operating agreement or other management agreement, as the case may be, or (iii) the provisions of any indenture, any material instrument or any material agreement to which the Borrower or any of its Subsidiaries is a party or is subject, or by which it, or its Property, is bound, or conflict with, or constitute a default under, or result in, or require, the creation or imposition of any Lien in, of or on the Property of the Borrower or a Subsidiary pursuant to the terms of, any such indenture, instrument or agreement. No order, consent, adjudication, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by the Borrower or any of its Subsidiaries, is required to be obtained by the Borrower or any of its Subsidiaries in connection with the execution and delivery of the Loan Documents, the borrowings under this Agreement, the

payment and performance by the Borrower of the Obligations or the legality, validity, binding effect or enforceability of any of the Loan Documents.

5.4. Financial Statements. The December 31, 2007, consolidated financial statements of the Borrower, audited by PricewaterhouseCoopers LLP, for the fiscal year ended December 31, 2007, and the unaudited consolidated balance sheet of the Borrower as of March 31, 2008, and the related unaudited statement of income and statement of cash flows for the three-month period then ended, copies of which have been furnished to each Lender, fairly present in all material respects (subject in the case of such balance sheet and statement of income for the period ended March 31, 2008, to year-end adjustments) the consolidated financial condition of the Borrower at such dates and the consolidated results of the operations of the Borrower for the periods ended on such dates, were prepared in accordance with generally accepted accounting principles in effect on the dates such statements were prepared (except for the absence of footnotes and subject to year end audit adjustments) and fairly present the consolidated financial condition and operations of the Borrower at such dates and the consolidated results of its operations for the periods then ended. Except as disclosed in the financial statements referred to above or the notes thereto, neither the Borrower nor any of the Subsidiaries has as of the Closing Date any material contingent liabilities.

5.5. Material Adverse Change. Since March 31, 2008, there has been no change in the business, Property, condition (financial or otherwise) or results of operations of the Borrower and its Subsidiaries (other than any Project Finance Subsidiary or Non-Material Subsidiary) which could reasonably be expected to have a Material Adverse Effect (a “Material Adverse Change”), except for the Disclosed Matters; provided, however, that neither (i) any ratings downgrade applicable to the Indebtedness of the Borrower or any of its Subsidiaries by Xxxxx’x or S&P nor (ii) the Borrower’s or any of its Subsidiaries’ inability to place commercial paper in the capital markets, shall, in and of themselves, be deemed events constituting a Material Adverse Change.

5.6. Taxes. The Borrower and its Subsidiaries have filed all United States federal tax returns and all other material tax returns which are required to be filed and have paid all taxes due pursuant to said returns or pursuant to any assessment received by the Borrower or any of its Subsidiaries, except in respect of such taxes, if any, as are being contested in good faith and as to which adequate reserves have been provided in accordance with Agreement Accounting Principles and as to which no Lien exists (except as permitted by Section 6.13.2). The Internal Revenue Service has closed audits of the consolidated United States federal income tax returns filed by the Borrower and its Subsidiaries through the calendar taxable year ending December 31, 2004. The Internal Revenue Service has not closed audits of the consolidated United States federal income tax returns filed by the Borrower and its Subsidiaries for subsequent periods. No claims have been, or are being, asserted with respect to such taxes that could reasonably be expected to result in a Material Adverse Effect, and no liens have been filed with respect to such taxes. The charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of any taxes or other governmental charges are adequate.

5.7. Litigation and Contingent Obligations. Other than the Disclosed Matters, there is no litigation, arbitration, governmental investigation, proceeding or inquiry pending or, to the knowledge of any of its officers, threatened against or affecting the Borrower or any of its

Subsidiaries which could reasonably be expected to have a Material Adverse Effect or which seeks to prevent, enjoin or delay the making of any Loans.

5.8. Subsidiaries.

On the basis of this consideration, the Borrower has concluded that, other than the Disclosed Matters, Environmental Laws cannot reasonably be expected to have a Material Adverse Effect. Except for the Disclosed Matters, and except with respect to any other matters that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, neither the Borrower nor any Subsidiary has received any notice to the effect that its operations are not in material compliance with any of the requirements of applicable Environmental Laws or are the subject of any federal or state investigation evaluating whether any remedial action is needed to respond to a release of any toxic or hazardous waste or substance into the environment.

ARTICLE VIII

ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

8.1. Acceleration. If any Default described in Section 7.6 or 7.7 occurs with respect to the Borrower or any of its Subsidiaries (other than any Project Finance Subsidiary or Non-Material Subsidiary or SPC), the obligations of the Lenders to make Loans hereunder to the Borrower shall automatically terminate and the Obligations of the Borrower shall immediately become due and payable without any election or action on the part of the Agent or any Lender. If any other Default occurs with respect to the Borrower or any of its Subsidiaries (other than any Project Finance Subsidiary, Non-Material Subsidiary or SPC to the extent excluded from such Default by the provisions of Article VII), the Required Lenders (or the Agent with the consent of the Required Lenders) may terminate or suspend the obligations of the Lenders to make Loans hereunder to the Borrower, or declare the Obligations to be due and payable, or both, whereupon the Obligations shall become immediately due and payable, without presentment, demand, protest or notice of any kind, all of which the Borrower hereby expressly waives.

If, after acceleration of the maturity of the Obligations or termination of the obligations of the Lenders to make Loans hereunder as a result of any Default (other than any Default as described in Section 7.6 or 7.7 with respect to the Borrower) and before any judgment or decree for the payment of the Obligations due shall have been obtained or entered, the Required Lenders (in their sole discretion) shall so direct, the Agent shall, by notice to the Borrower, rescind and annul such acceleration and/or termination.

8.2. Amendments. Subject to the provisions of this Section 8.2, the Required Lenders (or the Agent with the consent in writing of the Required Lenders) and the Borrower may enter into agreements supplemental hereto for the purpose of adding or modifying any provisions to the

Loan Documents or changing in any manner the rights of the Lenders or the Borrower hereunder or thereunder or waiving any Default hereunder or thereunder; provided, however, that no such supplemental agreement shall, without the consent of all of the Lenders (or, in the case of Section 8.2.2, all affected Lenders):

8.2.1 Extend the final maturity of any Loan or postpone any payment of principal of any Loan or forgive all or any portion of the principal amount thereof, or reduce the rate or extend the time of payment of interest or fees thereon (other than a waiver of the application of the default rate of interest pursuant to Section 2.14 hereof).

8.2.2 [omitted].

8.2.3 Reduce the percentage specified in the definition of Required Lenders or any other percentage of Lenders specified to be the Pro Rata Share in this Agreement to act on specified matters or amend the definition of “Pro Rata Share”.

8.2.4 Extend the Maturity Date, or reduce the amount or extend the payment date for, the mandatory payments required under Section 2.10(b), or increase the amount of the Commitment of any Lender hereunder, or permit the Borrower to assign its rights or obligations under this Agreement or change Section 2.15 or 2.8 in a manner that would alter the pro rata sharing of payments or the application of reductions of commitments on a ratable basis required thereby.

8.2.5 Amend this Section 8.2.

No amendment of any provision of this Agreement relating to the Agent shall be effective without the written consent of the Agent. The Agent may waive payment of the fee required under Section 12.3.3 without obtaining the consent of any other party to this Agreement. Notwithstanding the foregoing, any provision of this Agreement may be amended by an agreement in writing entered into by the Borrower, the Required Lenders and the Agent if (i) by the terms of such agreement any remaining Commitment of each Lender not consenting to the amendment provided for therein shall terminate upon the effectiveness of such amendment and (ii) at the time such amendment becomes effective, each Lender not consenting thereto receives payment in full of the principal of and interest accrued on each Advance made by it and all other amounts owing to it or accrued for its account under this Agreement.

8.3. Preservation of Rights. No delay or omission of the Lenders or the Agent to exercise any right under the Loan Documents shall impair such right or be construed to be a waiver of any Default or an acquiescence therein, and the making of a Loan notwithstanding the existence of a Default or Unmatured Default or the inability of the Borrower to satisfy the conditions precedent to such Loan shall not constitute any waiver or acquiescence. Any single or partial exercise of any such right shall not preclude any other or further exercise thereof or the exercise of any other right, and no waiver, amendment or other variation of the terms, conditions or provisions of the Loan Documents whatsoever shall be valid unless in writing signed by, or by

the Agent with the consent of, the requisite number of Lenders required pursuant to Section 8.2, and then only to the extent in such writing specifically set forth. All remedies contained in the Loan Documents or by law afforded shall be cumulative and all shall be available to the Agent and the Lenders until all of the Obligations have been paid in full.

The Borrower shall reimburse the Agent and the Arranger for any reasonable costs, internal charges and out-of-pocket expenses (including reasonable attorneys’ and paralegals’ fees and time charges of attorneys for the Agent, which attorneys may be employees of the Agent, and expenses of and fees for other advisors and professionals engaged by the Agent or the Arranger) paid or incurred by the Agent or the Arranger in connection with the investigation, preparation, negotiation, documentation, execution, delivery, syndication, distribution (including, without limitation, via the internet), review, amendment, modification

The Borrower hereby further agrees to indemnify the Agent, the Arranger, each Lender, their respective affiliates, and each of their directors, officers and employees against all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, all expenses of litigation or preparation therefor whether or not the Agent, the Arranger, any Lender or any affiliate is a party thereto, and all attorneys’ and paralegals’ fees, time charges and expenses of attorneys and paralegals of the party seeking indemnification, which attorneys and paralegals may or may not be employees of such party seeking indemnification) which any of them may pay or incur arising out of or relating to this Agreement, the other Loan Documents, the transactions contemplated hereby or the direct or indirect application or proposed application of the proceeds of any Loan hereunder except to the extent that they have resulted, as determined in a final non-appealable judgment by a court of competent jurisdiction, from the gross negligence or willful misconduct of the party seeking indemnification.

(iii)

[omitted].

(iv)

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

9.7. Numbers of Documents. All statements, notices, closing documents, and requests hereunder shall be furnished to the Agent with sufficient counterparts so that the Agent may furnish one to each of the Lenders, to the extent that the Agent deems necessary.

9.8. Accounting. Except as provided to the contrary herein, all accounting terms used in the calculation of any financial covenant or test shall be interpreted and all accounting determinations hereunder in the calculation of any financial covenant or test shall be made in accordance with Agreement Accounting Principles. If any changes in generally accepted accounting principles are hereafter required or permitted and are adopted by the Borrower or any

of its Subsidiaries with the agreement of its independent certified public accountants and such changes result in a change in the method of calculation of any of the financial covenants, tests, restrictions or standards herein or in the related definitions or terms used therein (“Accounting Changes”), the parties hereto agree, at the Borrower’s request, to enter into negotiations, in good faith, in order to amend such provisions in a credit neutral manner so as to reflect equitably such changes with the desired result that the criteria for evaluating the Borrower’s and its Subsidiaries’ financial condition shall be the same after such changes as if such changes had not been made; provided, however, until such provisions are amended in a manner reasonably satisfactory to the Agent and the Required Lenders, no Accounting Change shall be given effect in such calculations. In the event such amendment is entered into, all references in this Agreement to Agreement Accounting Principles shall mean generally accepted accounting principles as of the date of such amendment. Notwithstanding the foregoing, all financial statements to be delivered by the Borrower pursuant to Section 6.1 shall be prepared in accordance with generally accepted accounting principles in effect at such time.

9.9. Severability of Provisions.

None of the Borrower, the Agent, the Arranger or any Lender shall have any liability with respect to, and each of the Agent, the Arranger, each Lender and the Borrower hereby waives, releases and agrees not to xxx for, any special, indirect, consequential or punitive damages suffered by it in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby.

9.11. Confidentiality.

9.14. Disclosure. The Borrower and each Lender hereby acknowledge and agree that each Lender and its Affiliates from time to time may hold investments in, make other loans to or have other relationships with the Borrower and its Affiliates.

The Agent agrees to act as such contractual representative upon the express conditions contained in this Article X.

In its capacity as the Lenders’ contractual representative, the Agent (i) does not hereby assume any fiduciary duties to any of the Lenders, (ii) is a “representative” of the Lenders within the meaning of the term

“secured party” as defined in the New York Uniform Commercial Code and (iii) is acting as an independent contractor, the rights and duties of which are limited to those expressly set forth in this Agreement and the other Loan Documents. Each of the Lenders hereby agrees to assert no claim against the Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each Lender hereby waives.

The Agent shall have and may exercise such powers under the Loan Documents as are specifically delegated to the Agent by the terms of each thereof, together with such powers as are reasonably incidental thereto. The Agent shall have no implied duties or fiduciary duties to the Lenders, or any obligation to the Lenders to take any action thereunder except any action specifically provided by the Loan Documents to be taken by the Agent.

10.3. General Immunity. Neither the Agent nor any of its directors, officers, agents or employees shall be liable to the Borrower, the Lenders or any Lender for any action taken or omitted to be taken by it or them hereunder or under any other Loan Document or in connection herewith or therewith except to the extent such action or inaction is determined in a final, non-appealable judgment by a court of competent jurisdiction to have arisen from the gross negligence or willful misconduct of such Person.

10.5. Action on Instructions of Lenders. The Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and under any other Loan Document in accordance with written instructions signed by the Required Lenders (or all of the Lenders in the event that and to the extent that this Agreement expressly requires such), and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders. The Lenders hereby acknowledge that the Agent shall be under no duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or any other Loan Document unless it shall be requested in writing to do so by the Required Lenders (or all of the Lenders in the event that and to the extent that this Agreement expressly requires such). The Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Loan Document unless it shall first be indemnified to its satisfaction in writing by the

Lenders pro rata against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action.

10.6. Employment of Agents and Counsel. The Agent may execute any of its duties as Agent hereunder and under any other Loan Document by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Lenders, except as to money or securities received by it or its authorized agents, for the default or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. The Agent shall be entitled to advice of counsel concerning the contractual arrangement between the Agent and the Lenders and all matters pertaining to the Agent’s duties hereunder and under any other Loan Document.

10.7. Reliance on Documents; Counsel. The Agent shall be entitled to rely upon any Note, notice, consent, certificate, affidavit, letter, telegram, statement, paper or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and, in respect to legal matters, upon the opinion of counsel selected by the Agent, which counsel may be employees of the Agent.

10.8. Agent’s Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify the Agent ratably in proportion to the their Pro Rata Shares (determined as of the date of any such request by the Agent) (i) for any amounts not reimbursed by the Borrower for which the Agent is entitled to reimbursement by the Borrower under the Loan Documents, (ii) to the extent not paid by the Borrower, for any other expenses incurred by the Agent on behalf of the Lenders, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents (including, without limitation, for any expenses incurred by the Agent in connection with any dispute between the Agent and any Lender or between two or more of the Lenders) and (iii) to the extent not paid by the Borrower, for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Agent in any way relating to or arising out of the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including, without limitation, for any such amounts incurred by or asserted against the Agent in connection with any dispute between the Agent and any Lender or between two or more of the Lenders), or the enforcement of any of the terms of the Loan Documents or of any such other documents, provided that (i) no Lender shall be liable for any of the foregoing to the extent any of the foregoing is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Agent, (ii) any indemnification required pursuant to Section 3.5(vii) shall, notwithstanding the provisions of this Section 10.8, be paid by the relevant Lender in accordance with the provisions thereof and (iii) the Agent shall reimburse the Lenders for any amounts the Lenders have paid to the extent such amounts are subsequently recovered from the Borrower. The obligations of the Lenders under this Section 10.8 shall survive payment of the Obligations and termination of this Agreement.

10.9. Notice of Default. The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Unmatured Default hereunder unless the Agent has received written notice from a Lender or the Borrower referring to this Agreement describing such Default or Unmatured Default and stating that such notice is a “notice of default”. In the event

that the Agent receives such a notice, the Agent shall give prompt notice thereof to the Borrower and the Lenders.

10.10. Rights as a Lender. In the event the Agent is a Lender, the Agent shall have the same rights and powers hereunder and under any other Loan Document with respect to its Commitment and its Loans as any Lender and may exercise the same as though it were not the Agent, and the term “Lender” or “Lenders” shall, at any time when the Agent is a Lender, unless the context otherwise indicates, include the Agent in its individual capacity. The Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of trust, debt, equity or other transaction, in addition to those contemplated by this Agreement or any other Loan Document, with the Borrower or any of its Subsidiaries in which the Borrower or such Subsidiary is not restricted hereby from engaging with any other Person. The Agent, in its individual capacity, is not obligated to remain a Lender.

10.11. Independent Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent, the Arranger or any other Lender and based on the financial statements prepared by the Borrower and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Documents. Each Lender also acknowledges that it will, independently and without reliance upon the Agent, the Arranger 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 decisions in taking or not taking action under this Agreement and the other Loan Documents.

10.12. Successor Agent. The Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower, such resignation to be effective upon the appointment of a successor Agent or, if no successor Agent has been appointed, forty-five days after the retiring Agent gives notice of its intention to resign. The Agent may be removed at any time with or without cause by written notice received by the Agent from the Required Lenders, such removal to be effective on the date specified by the Required Lenders. Upon any such resignation or removal, the Required Lenders, with the consent of the Borrower (which consent shall not be unreasonably withheld or delayed; provided that such consent shall not be required in the event and continuation of a Default), shall have the right to appoint, on behalf of the Borrower and the Lenders, a successor Agent. If no successor Agent shall have been so appointed by the Required Lenders or consented to by the Borrower within thirty days after the resigning Agent’s giving notice of its intention to resign, then the resigning Agent may appoint, on behalf of the Borrower and the Lenders, a successor Agent. Notwithstanding the previous sentence, the Agent may at any time without the consent of the Borrower or any Lender, appoint any of its Affiliates which is a commercial bank as a successor Agent hereunder. If the Agent has resigned or been removed and no successor Agent has been appointed, the Lenders may perform all the duties of the Agent hereunder and the Borrower shall make all payments in respect of the Obligations to the applicable Lenders and for all other purposes shall deal directly with the Lenders. No successor Agent shall be deemed to be appointed hereunder until such successor Agent has accepted the appointment. Any such successor Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning or removed Agent. Upon the effectiveness of the resignation or removal of the Agent, the resigning

or removed Agent shall be discharged from its duties and obligations hereunder and under the Loan Documents. After the effectiveness of the resignation or removal of an Agent, the provisions of this Article X shall continue in effect for the benefit of such Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Agent hereunder and under the other Loan Documents. In the event that there is a successor to the Agent by merger, or the Agent assigns its duties and obligations to an Affiliate pursuant to this Section 10.12, then the term “Prime Rate” as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent.

10.13. Agent and Arranger Fees. The Borrower agrees to pay to the Agent and the Arranger, for their respective accounts, the agent and arranger fees agreed to by the Borrower, the Agent and the Arranger pursuant to the letter agreements dated June 5, 2008, or as otherwise agreed from time to time.

10.14. Delegation to Affiliates. The Borrower and the Lenders agree that the Agent may delegate any of its duties under this Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate’s directors, officers, agents and employees) which performs duties in connection with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other protective provisions to which the Agent is entitled under Articles IX and X.

10.15. Syndication Agent and Documentation Agents. The Lender identified in this Agreement as the “Syndication Agent” and the Lenders identified in this Agreement as the “Documentation Agents” shall have no right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, such Lenders shall not have or be deemed to have a fiduciary relationship with any other Lender. Each Lender hereby makes the same acknowledgements with respect to such Lenders as it makes with respect to the Agent in Section 10.11.

ARTICLE XI

SETOFF; RATABLE PAYMENTS

11.1. Setoff. In addition to, and without limitation of, any rights of the Lenders under applicable law, if the Borrower becomes insolvent, however evidenced, or any Default occurs, any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Indebtedness at any time held or owing by any Lender or any Affiliate of any Lender to or for the credit or account of the Borrower may be offset and applied toward the payment of the Obligations owing to such Lender, whether or not the Obligations, or any part thereof, shall then be due.

11.2. Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its Loans (other than payments received pursuant to Section 3.1, 3.2, 3.4, 3.5 or 9.6) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand, to purchase a participation in the Loans held by the other Lenders so that after such purchase each Lender will hold its Pro Rata Share of the Loans. If any Lender, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives

collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to their respective Pro Rata Shares of the Loans. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

ARTICLE XII

BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

12.1. Successors and Assigns; Designated Lenders.

12.1.1 Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Borrower, the Agent and the Lenders and their respective successors and assigns permitted hereby, except that (i) the Borrower shall not have the right to assign its rights or obligations under the Loan Documents without the prior written consent of the Agent and each Lender, (ii) any assignment by any Lender must be made in compliance with Section 12.3, and (iii) any transfer by Participants must be made in compliance with Section 12.2. Any attempted assignment or transfer by any party not made in compliance with this Section 12.1 shall be null and void, unless such attempted assignment or transfer is treated as a participation in accordance with Section 12.3.2. The parties to this Agreement acknowledge that clause (ii) of this Section 12.1 relates only to absolute assignments and this Section 12.1 does not prohibit assignments creating security interests, including, without limitation, (x) any pledge or assignment by any Lender of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank, (y) in the case of a Lender which is a Fund, any pledge or assignment of all or any portion of its rights under this Agreement and any Note to its trustee in support of its obligations to its trustee or (z) any pledge or assignment by any Lender of all or any portion of its rights under this Agreement and any Note to direct or indirect contractual counterparties in swap agreements relating to the Loans; provided, however, that no such pledge or assignment creating a security interest shall release the transferor Lender from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 12.3. The Agent may treat the Person which made any Loan or which holds any Note as the owner thereof for all purposes hereof unless and until such Person complies with Section 12.3; provided, however, that the Agent may in its discretion (but shall not be required to) follow instructions from the Person which made any Loan or which holds any Note to direct payments relating to such Loan or Note to another Person. Any assignee of the rights to any Loan or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the owner of the rights to any Loan (whether or not a Note has been

issued in evidence thereof), shall be conclusive and binding on any subsequent holder or assignee of the rights to such Loan.

12.1.2 Designated Lenders.

(i)

Subject to the terms and conditions set forth in this Section 12.1.2, any Lender may from time to time elect to designate an Eligible Designee to provide all or any part of the Loans to be made by such Lender pursuant to this Agreement; provided that the designation of an Eligible Designee by any Lender for purposes of this Section 12.1.2 shall be subject to the approval of the Agent (which consent shall not be unreasonably withheld or delayed). Upon the execution by the parties to each such designation of an agreement in the form of Exhibit F hereto (a “Designation Agreement”) and the acceptance thereof by the Agent, the Eligible Designee shall become a Designated Lender for purposes of this Agreement. The Designating Lender shall thereafter have the right to permit the Designated Lender to provide all or a portion of the Loans to be made by the Designating Lender pursuant to the terms of this Agreement and the making of such Loans or portion thereof shall satisfy the obligations of the Designating Lender to the same extent, and as if, such Loan was made by the Designating Lender. As to any Loan made by it, each Designated Lender shall have all the rights a Lender making such Loan would have under this Agreement and otherwise; provided, (x) that all voting rights under this Agreement shall be exercised solely by the Designating Lender, (y) each Designating Lender shall remain solely responsible to the other parties hereto for its obligations under this Agreement, including the obligations of a Lender in respect of Loans made by its Designated Lender and (z) no Designated Lender shall be entitled to reimbursement under Article III hereof for any amount which would exceed the amount that would have been payable by the Borrower to the Lender from which the Designated Lender obtained any interests hereunder. No additional Notes shall be required with respect to Loans provided by a Designated Lender; provided, however, to the extent any Designated Lender shall advance funds, the Designating Lender shall be deemed to hold the Notes in its possession as an agent for such Designated Lender to the extent of the Loan funded by such Designated Lender. Such Designating Lender shall act as administrative agent for its Designated Lender and give and receive notices and communications hereunder. Any payments for the account of any Designated Lender shall be paid to its Designating Lender as administrative agent for such Designated Lender and neither the Borrower nor the Agent shall be responsible for any Designating Lender’s application of such payments. In addition, any Designated Lender may (1) with notice to, but without the consent of, the Borrower or the Agent, assign all or portions of its interests in any Loans to its Designating Lender or to any financial institution consented to by the Agent providing liquidity and/or credit facilities to or for the account of such Designated Lender and (2) subject to advising any such Person that such information is to be treated as confidential in accordance with Section 9.11, disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any guarantee, surety or credit or liquidity enhancement to such Designated Lender.

(ii)

Each party to this Agreement hereby agrees that it shall not institute against, or join any other Person in instituting against, any Designated Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding or other proceedings under any federal or state bankruptcy or similar law for one year and a day after the payment in full of all outstanding senior indebtedness of any Designated Lender. This Section 12.1.2 shall survive the termination of this Agreement.

12.2. Participations.

12.2.1 Permitted Participants; Effect. Any Lender may at any time sell to one or more banks or other entities (“Participants”) participating interests in any Loan of such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender under the Loan Documents. In the event of any such sale by a Lender of participating interests to a Participant, such Lender’s obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the owner of its Loan and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents, all amounts payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interests, and the Borrower and the Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under the Loan Documents.

12.2.2 Voting Rights. Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification or waiver with respect to any Loan or Commitment in which such Participant has an interest which would require consent of all of the Lenders pursuant to the terms of Section 8.2.

12.2.3 Benefit of Certain Provisions. The Borrower agrees that each Participant shall be deemed to have the right of setoff provided in Section 11.1 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents, provided that each Lender shall retain the right of setoff provided in Section 11.1 with respect to the amount of participating interests sold to each Participant. The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 11.1, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 11.2 as if each Participant were a Lender. The Borrower further agrees that each Participant shall be entitled to the benefits of Sections 3.1, 3.2, 3.4 and 3.5 to the same extent as if it were a Lender and had acquired its interest by assignment

pursuant to Section 12.3, provided that (i) a Participant shall not be entitled to receive any greater payment under Section 3.1, 3.2 or 3.5 than the Lender who sold the participating interest to such Participant would have received had it retained such interest for its own account, unless the sale of such interest to such Participant is made with the prior written consent of the Borrower, and (ii) any Participant not incorporated under the laws of the United States of America or any State thereof agrees to comply with the provisions of Section 3.5 to the same extent as if it were a Lender.

12.3. Assignments.

12.3.1 Permitted Assignments. Any Lender may at any time assign to one or more banks or other entities (“Purchasers”) all or any part of its rights and obligations under the Loan Documents. Such assignment shall be evidenced by an agreement substantially in the form of Exhibit C or in such other form as may be agreed to by the parties thereto (each such agreement, an “Assignment Agreement”). Each such assignment with respect to a Purchaser which is not a Lender or an Affiliate of a Lender or an Approved Fund shall either be in an amount equal to the entire applicable Commitment or Loan of the assigning Lender or (unless each of the Borrower and the Agent otherwise consents) be in an aggregate amount not less than $5,000,000. The amount of the assignment shall be based on the Commitment or the Loan subject to the assignment, determined as of the date of such assignment or as of the “Trade Date,” if the “Trade Date” is specified in the Assignment Agreement. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement.

12.3.2 Consents. The consent of the Borrower shall be required prior to an assignment becoming effective unless the Purchaser is a Lender, an Affiliate of a Lender or an Approved Fund, provided that the consent of the Borrower shall not be required if (i) a Default has occurred and is continuing or (ii) such assignment is in connection with the physical settlement of any Lender’s obligations to direct or indirect contractual counterparties in swap agreements relating to the Loans; provided, that the assignment without the Borrower’s consent pursuant to clause (ii) shall not increase the Borrower’s liability under Section 3.5. The consent of the Agent shall be required prior to an assignment becoming effective. Any consent required under this Section 12.3.2 shall not be unreasonably withheld or delayed.

12.3.3 Effect; Effective Date. Upon (i) delivery to the Agent of an Assignment Agreement, together with any consents required by Sections 12.3.1 and 12.3.2, and (ii) payment of a $3,500 fee to the Agent for processing such assignment (unless such fee is waived by the Agent), such assignment shall become effective on the effective date specified in such assignment. The Assignment Agreement shall contain a representation and warranty by the Purchaser to the effect that none of the funds, money, assets or other consideration used to make the purchase and assumption of the Commitment

and Loan under the applicable Assignment Agreement constitutes “plan assets” as defined under ERISA and that the rights, benefits and interests of the Purchaser in and under the Loan Documents will not be “plan assets” under ERISA. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to this Agreement and any other Loan Document executed by or on behalf of the Lenders and shall have all the rights, benefits and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party thereto, and the transferor Lender shall be released with respect to the Commitment or Loan assigned to such Purchaser without any further consent or action by the Borrower, the Lenders or the Agent. In the case of an assignment covering all of the assigning Lender’s rights, benefits and obligations under this Agreement, such Lender shall cease to be a Lender hereunder but shall continue to be entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan Documents which survive payment of the Obligations and termination of the Loan Documents. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.3 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 12.2. Upon the consummation of any assignment to a Purchaser pursuant to this Section 12.3.3, the transferor Lender, the Agent and the Borrower shall, if the transferor Lender or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so that, upon cancellation and surrender to the Borrower of the Notes (if any) held by the transferor Lender, new Notes or, as appropriate, replacement Notes are issued to such transferor Lender, if applicable, and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Commitments or Loans, as adjusted pursuant to such assignment.

12.3.4 Register. The Agent, acting solely for this purpose as an agent of the Borrower (and the Borrower hereby designates the Agent to act in such capacity), shall maintain at one of its offices in New York, New York a copy of each Assignment and Assumption delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of and interest on the Loans owing to, each Lender pursuant to the terms hereof from time to time and whether such Lender is an original Lender or assignee of another Lender pursuant to an assignment under this Section 13.3. The entries in the Register shall be conclusive, absent manifest error and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

12.4. Dissemination of Information. The Borrower authorizes each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a “Transferee”) and any prospective Transferee any and all information in such Lender’s possession concerning the creditworthiness of the Borrower and their Subsidiaries; provided that each Transferee and prospective Transferee agrees to be bound by Section 9.11 of this Agreement.

12.5. Tax Certifications. If any interest in any Loan Document is transferred to any Transferee which is not incorporated under the laws of the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 3.5(iv).

June [ ], 2008

To the Lenders (as defined below) and

JPMorgan Chase Bank, N.A., as Agent

000 Xxxx Xxxxxx

Xxx Xxxx, XX 00000

Dear Ladies and Gentlemen:

I, S.R. Xxxxxxxx, am the Senior Vice President, General Counsel and Secretary of Ameren Corporation, a Missouri corporation (the “Company”), and certain of its subsidiaries. I, or lawyers under my direction, have acted as counsel for the Company in connection with the negotiation and execution of that certain Credit Agreement dated as of June [25], 2008 (the “Credit Agreement”) among the Company, the lending institutions identified therein as “Lenders,” JPMorgan Chase Bank, N.A., as Agent, Barclays Bank PLC, as Syndication Agent, Bank of Tokyo-Mitsubishi UFJ, Ltd., as Co-Documentation Agent and BNP Paribas, as Co-Documentation Agent. Terms defined in the Credit Agreement are used herein with the same meanings.

In rendering the opinion expressed below, I, or lawyers under my direction, have examined originals or copies, certified or otherwise identified to my satisfaction, of such documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as I have deemed necessary or advisable for purposes of this opinion.

In making the examinations described above, I have assumed without independent investigation the capacity of natural persons (other than the office held by each representative of the Company) as reflected adjacent to such individual’s signature on the Loan Documents (as defined below), the genuineness of all signatures (other than those of representatives of the Company appearing on the Loan Documents), the authenticity of all documents furnished to me as originals, the conformity to originals of all documents furnished to me as certified or photostatic copies and the authenticity of the originals of such documents. In addition, I have assumed without independent investigation that (i) the Credit Agreement has been duly authorized, executed and delivered by the Lenders and the Agent, and constitutes their valid, lawful and binding obligation and agreement and (ii) there is no separate agreement, undertaking, or course of dealing modifying, varying or waiving any of the terms of the Loan Documents. As to matters of fact not independently established by me relevant to the opinions set forth herein, I have relied without independent investigation on the representations contained in the Credit Agreement and in certificates of public officials and responsible representatives of the Company furnished to me; provided, however, that I advise that in the course of my representation of the Company, I have obtained no information that leads me to believe that any such representation or certificate is untrue or misleading in any material respect.

Upon the basis of and subject to the foregoing, I am of the opinion that:

1. The Company is a corporation duly and properly incorporated, validly existing and in good standing under the laws of the State of Missouri, has all requisite authority to conduct its business as presently conducted and (except to the extent that the failure to have so qualified to do business would not have resulted and could not reasonably be expected to result in a Material Adverse Effect) is qualified to do business in each jurisdiction in which its business is conducted.

2. The Company has the power and authority and legal right to execute and deliver, and to perform its obligations under, the Credit Agreement and the Notes (collectively, the (“Loan Documents”). The execution and delivery of, and the performance of its obligations under, the Loan Documents by the Company have been duly authorized by proper proceedings, and the Loan Documents to which the Company is a party constitute legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as enforceability may be limited by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, or similar laws relating to or affecting the enforcement of creditors’ rights generally; (ii) general equitable principles (whether considered in a proceeding in equity or at law); and (iii) requirements of reasonableness, good faith and fair dealing.

3. Neither the execution and delivery by the Company of the Loan Documents, nor the consummation of the transactions therein contemplated, nor compliance with the provisions thereof, nor the performance of the obligations thereunder violate (i) any law, rule or regulation of the State of Missouri or the United States of America, or any order, writ, judgment, injunction, decree or award binding on the Company, (ii) the Company’s articles or certificate of incorporation or by-laws or (iii) the provisions of any indenture or material instrument or agreement to which the Company or any of its Subsidiaries is a party or is subject, or by which it, or its Property, is bound, or conflict with, or constitute a default under, or result in, or require, the creation or imposition of any Lien in, of or on the Property of the Company or any of its Subsidiaries pursuant to the terms of, any such indenture, instrument or agreement. No order, consent, adjudication, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by the Company or any of its Subsidiaries, is required to be obtained by the Company or any such Subsidiary in connection with the execution and delivery of the Loan Documents, the borrowings thereunder, the payment and performance by the Company of the obligations thereunder or the legality, validity, binding effect or enforceability as to the Company of any of the Loan Documents.

4. Except for the Disclosed Matters, there is no litigation, arbitration, governmental investigation, proceeding or inquiry currently existing, or, to the best of my knowledge after due inquiry, pending or threatened against or affecting the Company or any of its Subsidiaries, which, if determined adversely to the Company or any such Subsidiary, could reasonably be expected to have a Material Adverse Effect or which seeks to prevent, enjoin or delay the making of the Loans or would adversely effect the legality, validity or enforceability of the Loan Documents as to the Company or the ability of the Company to perform the transactions contemplated therein.

5. The Company is not an “investment company” or a company “controlled” by an “investment company,” within the meaning of the Investment Company Act of 1940, as amended.

6. No federal governmental consents, approvals, authorizations, registrations, declarations or filings are required in connection with the execution, delivery and/or performance by the Company of the Loan Documents.

7. In a properly presented case, a Missouri court or a federal court applying Missouri choice of law rules should give effect to the choice of law provisions of the Loan Documents and should hold that the Loan Documents are to be governed by the laws of the State of New York rather than the laws of the State of Missouri. In rendering the foregoing opinion, I note that by their terms the Loan Documents expressly selects New York law as the law governing their interpretation and that the Loan Documents were delivered to the Agent in New York. The choice of law provisions of the Loan Documents are not voidable under the laws of the State of Missouri. Notwithstanding the foregoing, even if a Missouri court or a federal court holds that the Loan Documents are to be governed by the laws of the State of Missouri, the Loan Documents would constitute a legal, valid and binding obligation of the Company, enforceable against the Company under Missouri law (including usury provisions) in accordance with their terms, except as enforceability may be limited by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, or similar laws relating to or affecting the enforcement of creditors’ rights generally; (ii) general equitable principles (whether considered in a proceeding in equity or at law); and (iii) requirements of reasonableness, good faith and fair dealing.

I express no opinion as to the compliance or noncompliance, or the effect of the compliance or noncompliance, of any addressee with any state or federal laws or regulations applicable to it by reason of its status as or affiliation with a federally insured depository institution.

I am a member of the Bar of the State of Missouri and the foregoing opinion is limited to the laws of the State of Missouri and the Federal laws of the United States of America typically relevant to a transaction of this type. I note that the Loan Documents are governed by the laws of the State of New York and, for purposes of the opinion expressed in opinion paragraph 2 above and with your permission, I have assumed that the laws of the State of New York do not differ from the laws of the State of Missouri in any manner that would render such opinion incorrect. This opinion is rendered solely to you in connection with the above matter. This opinion may not be relied upon by you for any other purpose or relied upon by any other Person (other than your successors and assigns as Lenders) without my prior written consent. Notwithstanding anything in this opinion letter to the contrary, you may disclose this opinion (i) to prospective successors and assigns of the addressees hereof, (ii) to regulatory authorities having jurisdiction over any of the addressees hereof or their successors and assigns, and (iii) pursuant to valid legal process, in each case without my prior consent.

This opinion is delivered as of the date hereof and I undertake no, and disclaim any, obligation to advise you of any change in matters of law or fact set forth herein or upon which this opinion is based.

Very truly yours,

By: ___________________________________
