such Competitive Bid, and (v) except pursuant to clause (iv) above, no Competitive Bid shall be accepted for a Competitive Loan unless such Competitive Loan is in a minimum principal amount of $5,000,000 and an integral multiple of $1,000,000; provided further that if a Competitive Loan must be in an amount less than $5,000,000 because of the provisions of clause (iv) above, such Competitive Loan may be for a minimum of $1,000,000 or any integral multiple thereof, and in calculating the pro rata allocation of acceptances of portions of multiple Competitive Bids at a particular Competitive Bid Rate pursuant to clause (iv) the amounts shall be rounded to integral multiples of $1,000,000 in a manner determined by the applicable Borrower. A notice given by a Borrower pursuant to this paragraph shall be irrevocable.

(f) The Agent shall promptly notify each bidding Lender by telecopy whether or not its Competitive Bid has been accepted (and, if so, the amount and Competitive Bid Rate so accepted), and each successful bidder will thereupon become bound, subject to the terms and conditions hereof, to make the Competitive Loan in respect of which its Competitive Bid has been accepted.

2.5. Swingline Loans. (a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make Swingline Loans to each Borrower from time to time during the period from and including the Closing Date and prior to the Availability Termination Date for such Borrower in an aggregate principal amount at any time outstanding that will not result in (i) the aggregate principal amount of the outstanding Swingline Loans exceeding $40,000,000, (ii) the Aggregate Outstanding Credit Exposure exceeding the Aggregate Commitment, (iii) the Revolving Credit Exposure of any Lender exceeding its Commitment or (iv) the Borrower Credit Exposure of any Borrower exceeding the Borrower Sublimit for such Borrower; provided that the Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan.

(b) To request a Swingline Loan, a Borrower shall notify the Agent of such request by telephone not later than 3:00 p.m., New York City time, on the day of the proposed Swingline Loan. Each such telephonic notice shall be irrevocable and shall be confirmed promptly by hand delivery or facsimile to the Agent of an executed written notice. Each such telephonic and written notice shall specify the requested date (which shall be a Business Day) and the amount of the requested Swingline Loan and the location and number of the account of the Borrower to which funds are to be disbursed or, in the case of any Swingline Loan requested to finance the reimbursement of an LC Disbursement as provided in Section 2.6(e), the identity of the Issuing Bank that has made such LC Disbursement. Promptly following the receipt of a notice in accordance with this Section, the Agent shall advise the Swingline Lender of the details thereof. The Swingline Lender shall make each Swingline Loan available to the Borrower by means of a wire transfer to the account specified in such notice or to the applicable Issuing Bank, as the case may be.

(c) The Swingline Lender may by written notice given to the Agent not later than 10:00 a.m., New York City time, on any Business Day require the Lenders to acquire participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such notice shall specify the aggregate amount of the Swingline Loans in which the Lenders will be required to participate. Promptly upon receipt of such notice, the Agent will give notice thereof to each Lender, specifying in such notice such Lender’s Pro Rata Share of such Swingline Loan or Loans. Each Lender hereby absolutely and unconditionally agrees to pay, upon receipt of notice as provided above, to the Agent, for the account of the Swingline Lender, such Lender’s Pro Rata Share of such Swingline Loan or Loans. Each Lender acknowledges and agrees that, in making any Swingline Loan, the Swingline Lender shall be entitled to rely, and shall not incur any liability for relying, upon the representation and warranty of the applicable Borrower deemed made pursuant to Section 4.2, unless, at least one Business Day prior to the time such Swingline Loan was made, the Required Lenders shall have notified the Swingline Lender (with a copy to the Agent) in writing that, as a result of one or more events or circumstances described in such notice, one or more of the conditions precedent set forth in Section 4.2.1 or 4.2.2 would not be satisfied if such Swingline Loan were then made (it being understood and agreed that, in the event the Swingline Lender shall have received any such notice, it shall have no obligation to make any Swingline Loan until and unless it shall be satisfied that the events and circumstances described in such notice shall have been cured or otherwise shall have ceased to exist). Each Lender further acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of an Unmatured Default or any reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Lender shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.11 with respect to Loans made by such Lender (and Section 2.11 shall apply, mutatis mutandis, to the payment obligations of the Lenders pursuant to this paragraph), and the Agent shall promptly remit to the Swingline Lender the amounts so received by it from the Lenders. The Agent shall notify the applicable Borrower of any participations in any Swingline Loan acquired pursuant to this paragraph, and thereafter payments in respect of such Swingline Loan shall be made to the Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from the applicable Borrower (or other Person on behalf of such Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Agent; any such amounts received by the Agent shall be promptly remitted by the Agent to the Lenders that shall have made their payments pursuant to this paragraph and to the Swingline Lender, as their interests may appear; provided that any such payment so remitted shall be repaid to the Swingline Lender or to the Agent, as applicable, if and to the extent such payment is required to be refunded to the applicable Borrower for any reason. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not constitute a Loan and shall not relieve the applicable Borrower of its obligation to repay such Swingline Loan.

(a) General. Subject to the terms and conditions set forth herein, (i) each Borrower may request the issuance of Letters of Credit for its own account and (ii) the Company may request the issuance of Letters of Credit for its own account and, jointly, for the account of any of its subsidiaries (other than the Borrowing Subsidiary, Genco or any Illinois Utility) (and in each case under this clause (ii), the Company shall be considered the sole Borrower under such Letter of Credit for purposes of this Agreement notwithstanding any listing of any subsidiary of the Company as an account party or applicant with respect to such Letter of Credit), in each case in a form reasonably acceptable to the Agent and the applicable Issuing Bank, at any time and from time to time prior to the Availability Termination Date for such Borrower (with respect to any Letter of Credit referred to in clause (i) of this sentence) or the Company (with respect to any Letter of Credit referred to in clause (ii) of this sentence), as the case may be. Each Existing Letter of Credit shall be deemed, for all purposes of this Agreement (including paragraphs (d) and (e) of this Section), to be a Letter of Credit issued hereunder for the account of the applicable Borrower thereunder. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by a Borrower to, or entered into by a Borrower with, an Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control. The Company unconditionally and irrevocably agrees that, in connection with any Letter of Credit referred to in clause (ii) of the first sentence of this paragraph, it will be fully responsible for the reimbursement of LC Disbursements, the payment of interest thereon and the payment of LC Participation Fees and other fees due under Section 2.8.2 to the same extent as if it were the sole account party in respect of such Letter of Credit (the Company hereby irrevocably waiving any defenses that might otherwise be available to it as a guarantor of the obligations of any subsidiary that shall be a joint account party in respect of any such Letter of Credit).

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the applicable Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the applicable Issuing Bank) to the applicable Issuing Bank and the Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) of this Section), the amount of such Letter of Credit, the account party or account parties with respect to such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by the applicable Issuing Bank, such Borrower also shall submit a letter of credit application on such Issuing Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit, such Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension (i) the Aggregate Outstanding Credit Exposure will not exceed the Aggregate Commitment, (ii) the Revolving Credit Exposure of any Lender will not exceed its Commitment, (iii) the Borrower Credit Exposure of any Borrower will not exceed the Borrower Sublimit of such Borrower, (iv) the portion of the LC Exposure attributable to Letters of Credit

issued by the applicable Issuing Bank will not, unless such Issuing Bank shall so agree, exceed the LC Commitment of such Issuing Bank and (v) the LC Exposure will not exceed 25% of the Aggregate Commitment. Notwithstanding the foregoing, no Issuing Bank shall be required to issue any Letter of Credit if (x) any order, judgment or decree of any governmental authority shall enjoin or restrain, or by its terms purport to enjoin or restrain, such Issuing Bank from issuing such Letter of Credit or (y) any applicable law or any order, request or directive (whether or not having the force of law) of any governmental authority with jurisdiction over such Issuing Bank shall prohibit, or request that such Issuing Bank refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or impose upon such Issuing Bank any restriction, reserve or capital requirement with respect to such Letter of Credit not in effect on the Closing Date for which such Issuing Bank is not otherwise compensated hereunder or any unreimbursed loss, cost or expense not applicable to such Issuing Bank on the Closing Date, which such Issuing Bank deems in good faith to be material to it and for which such Issuing Bank is not otherwise compensated hereunder. If the Required Lenders notify the Issuing Banks that a Default exists with respect to any Borrower and instruct the Issuing Banks to suspend the issuance, amendment, renewal or extension of Letters of Credit for the account of such Borrower, no Issuing Bank shall issue, amend, renew or extend any Letter of Credit for the account of such Borrower or the Company without the consent of the Required Lenders until such notice is withdrawn by the Required Lenders (and each Lender that shall have delivered such notice agrees promptly to withdraw it at such time as no Default exists).

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is five Business Days prior to the Maturity Date for the applicable Borrower; provided that any Letter of Credit may contain customary automatic renewal provisions agreed upon by the applicable Borrower and the applicable Issuing Bank pursuant to which the expiration date of such Letter of Credit shall automatically be extended for a period of up to 12 months (but not to a date later than the date that is five Business Days prior to the Maturity Date for the applicable Borrower, unless otherwise permitted pursuant to the immediately succeeding proviso), subject to a right on the part of such Issuing Bank to prevent any such renewal from occurring by giving notice to the beneficiary in advance of any such renewal; provided, further that, with the prior consent of the Agent and the applicable Issuing Bank, a Letter of Credit may be extended beyond the fifth Business Day prior to the Maturity Date for the applicable Borrower so long as the applicable Borrower shall have deposited, or substantially concurrently with such extension shall deposit, in an account with the applicable Issuing Bank, for the benefit of the Lenders and such Issuing Bank, as cash collateral pursuant to documentation reasonably satisfactory to the Agent and such Issuing Bank, an amount in cash equal to the aggregate amount of all outstanding Letters of Credit issued for its account by such Issuing Bank that have an expiration date later than the fifth Business Day prior to the Maturity Date for the applicable Borrower.

(d) Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the applicable Issuing Bank or the Lenders, such Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from such Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Pro Rata Share of the aggregate amount available to be drawn under

such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Agent, for the account of such Issuing Bank, such Lender’s Pro Rata Share of each LC Disbursement made by such Issuing Bank and not reimbursed by the applicable Borrower on the date due as provided in paragraph (e) of this Section, or of any reimbursement payment required to be refunded to the applicable Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If an Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the applicable Borrower, severally and not jointly with the other Borrower, shall reimburse such LC Disbursement by paying to the Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on the date that such LC Disbursement is made, if such Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been received by such Borrower prior to such time on such date, then not later than 12:00 noon, New York City time, on (i) the Business Day that such Borrower receives such notice, if such notice is received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day immediately following the day that such Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that, if such LC Disbursement is not less than $1,000,000, such Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.1 or 2.5 that such payment be financed with a Floating Rate Advance or a Swingline Loan to such Borrower in an equivalent amount and, to the extent so financed, such Borrower’s obligation to make such payment shall be discharged and replaced by the resulting Floating Rate Advance or Swingline Loan. If such Borrower fails to make such payment when due, the Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from such Borrower in respect thereof and such Lender’s Pro Rata Share thereof. Promptly following receipt of such notice, each Lender shall pay to the Agent its Pro Rata Share of the payment then due from such Borrower, in the same manner as provided in Section 2.11 with respect to Loans made by such Lender (and Section 2.11 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Agent shall promptly pay to such Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Agent of any payment from such Borrower pursuant to this paragraph, the Agent shall distribute such payment to such Issuing Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse such Issuing Bank, then to such Lenders and such Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse an Issuing Bank for any LC Disbursement (other than the funding of a Floating Rate Advance or a Swingline Loan as contemplated above) shall not constitute a Loan and shall not relieve such Borrower of its obligation to reimburse such LC Disbursement.

(f) Obligations Absolute. Each Borrower’s obligation to reimburse LC Disbursements as provided in paragraph (e) of this Section shall be several and not joint with the other Borrower, shall be absolute, unconditional and irrevocable, and shall be performed strictly in

accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by an Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, such Borrower’s obligations hereunder. None of the Agent, the Lenders or the Issuing Banks, or any of their respective affiliates, directors, officers or employees, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the applicable Issuing Bank; provided that the foregoing shall not be construed to excuse an Issuing Bank from liability to a Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by each Borrower to the extent permitted by applicable law) suffered by such Borrower that are caused by such Issuing Bank’s wrongful honor or rejection of any drawing under such Letter of Credit to the extent arising out of the Issuing Bank’s gross negligence or willful misconduct (as finally determined by a court of competent jurisdiction). In furtherance of the foregoing and without limiting the generality thereof, but subject to any non-waivable provisions of the laws and/or other rules to which a Letter of Credit is subject, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, an Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g) Disbursement Procedures. The applicable Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. Such Issuing Bank shall promptly notify the Agent and the applicable Borrower by telephone (confirmed by telecopy) of such demand for payment and whether such Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve such Borrower of its obligation to reimburse such Issuing Bank and the Lenders with respect to any such LC Disbursement.

(h) Interim Interest. If an Issuing Bank shall make any LC Disbursement, then, unless the applicable Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that such Borrower reimburses such LC Disbursement, at the rate per annum then applicable to Floating Rate Advances; provided that, if such Borrower fails to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.14 shall apply. Interest accrued

pursuant to this paragraph shall be for the account of such Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of this Section to reimburse such Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i) Cash Collateralization. If any Default with respect to a Borrower shall occur and be continuing, on the Business Day that such Borrower receives notice from the Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Lenders with LC Exposures representing greater than 50% of the total LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph, such Borrower shall deposit in an account with the Agent, in the name of the Agent and for the benefit of the Lenders, an amount in cash equal to the portion of the LC Exposure as of such date attributable to Letters of Credit issued for the account of such Borrower; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Default with respect to such Borrower described in Section 7.6 or 7.7. Such deposit shall be held by the Agent as collateral for the payment and performance of the Obligations of such Borrower under this Agreement. The Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made only if and to the extent requested by such Borrower and then only at the option and sole discretion of the Agent, and all at such Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Agent to reimburse each Issuing Bank for LC Disbursements under Letters of Credit issued for the account of such Borrower for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of future reimbursement obligations under Letters of Credit issued for the account of such Borrower or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with LC Exposures representing greater than 50% of the total LC Exposure), be applied to satisfy other Obligations of such Borrower under this Agreement. If any Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of a Default with respect to such Borrower, such amount (to the extent not applied as aforesaid) shall be returned to such Borrower within three Business Days after all Defaults with respect to such Borrower have been cured or waived. If at any time the cash collateral of any Borrower shall exceed such portion of the LC Exposure as of such date attributable to Letters of Credit issued for the account of such Borrower, the Agent shall apply such excess funds to the payment of such Borrower’s Obligations or (i) if no such Obligations are then due and owing and no Default with respect to such Borrower shall exist, shall release such excess funds to such Borrower or (ii) if no such Obligations are outstanding (other than contingent Obligations in respect of Letters of Credit which are fully collateralized), such excess amount shall be released to such Borrower notwithstanding the existence of a Default in respect of such Borrower.

(j) Designation of Additional Issuing Banks. From time to time, the Borrowers may by notice to the Agent and the Lenders designate as additional Issuing Banks one or more Lenders that agree to serve in such capacity as provided below. The acceptance by a Lender of any appointment as an Issuing Bank hereunder shall be evidenced by an agreement (an “Issuing Bank Agreement”), which shall be in a form satisfactory to the Borrowers and the Agent, shall

set forth the LC Commitment of such Lender and shall be executed by such Lender, the Borrowers and the Agent and, from and after the effective date of such agreement, (i) such Lender shall have all the rights and obligations of an Issuing Bank under this Agreement and the other Loan Documents and (ii) references herein and in the other Loan Documents to the term “Issuing Bank” shall be deemed to include such Lender in its capacity as an Issuing Bank.

2.7. Types of Advances. Revolving Advances may be Floating Rate Advances or Eurodollar Advances, or a combination thereof, selected by the applicable Borrower in accordance with Sections 2.11 and 2.12. Competitive Loans may be Eurodollar Rate Advances or Fixed Rate Advances, or a combination thereof, selected by the applicable Borrower in accordance with Section 2.4. Each Swingline Loan shall be a Floating Rate Advance.

2.8. Facility Fee; Letter of Credit Fees; Reductions in Aggregate Commitment and Borrower Sublimits.

2.8.1 Facility Fee. Each Borrower agrees, severally and not jointly with the other Borrower, to pay to the Agent for the account of each Lender a facility fee (the “Facility Fee”) at a per annum rate equal to such Borrower’s Applicable Fee Rate on its Contribution Percentage of such Lender’s Commitment (whether used or unused) from and including the Closing Date to and including the Facility Termination Date for such Borrower, payable quarterly in arrears on each Payment Date hereafter and on the Facility Termination Date for such Borrower; provided, that if any Lender continues to have Revolving Credit Exposure attributable to such Borrower hereunder after the Facility Termination Date for such Borrower (excluding any Revolving Credit Exposure in respect of LC Exposure which is cash collateralized hereunder), then the Facility Fee shall continue to accrue on the aggregate principal amount of such Revolving Credit Exposure until such Lender ceases to have any such Revolving Credit Exposure, and shall be payable on demand.

2.8.2 Letter of Credit Fees. Each Borrower agrees, severally and not jointly with the other Borrower, to pay (i) to the Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit issued for the account of such Borrower (the “LC Participation Fee”), which shall accrue at the Applicable Fee Rate on the average daily amount of that portion of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) attributable to Letters of Credit issued for the account of such Borrower during the period from and including the Closing Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any such LC Exposure, and (ii) to each Issuing Bank a fronting fee, which shall accrue at the rate or rates per annum separately agreed upon between such Borrower and such Issuing Bank on the average daily amount of the LC Exposure attributable to Letters of Credit issued by such Issuing Bank for the account of such Borrower (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Closing Date to but excluding the later of the date of termination of such

Issuing Bank’s LC Commitment and the date on which there ceases to be any such LC Exposure attributable to Letters of Credit issued by such Issuing Bank for such Borrower, as well as each Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit issued by such Issuing Bank for the account of such Borrower or processing of drawings thereunder. LC Participation Fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable on the third Business Day following such last day, commencing on the first such date to occur after the Closing Date; provided that all such fees accrued for the account of any Borrower shall be payable on the Availability Termination Date for such Borrower and any such fees accruing after the Availability Termination Date for such Borrower shall be payable on demand. Any other fees payable to an Issuing Bank pursuant to this paragraph shall be payable promptly upon receipt of an invoice therefor in reasonable detail.

2.8.3 Termination of and Reductions in Aggregate Commitment and Borrower Sublimits. The Commitments will automatically terminate on the Commitment Termination Date. The Company (on behalf of itself and the Borrowing Subsidiary) may permanently reduce the Aggregate Commitment (with or without reducing any Borrower Sublimit) and the Borrowing Subsidiary, or the Company, may permanently reduce its Borrower Sublimit (with or without reducing the Aggregate Commitment), in each case, in whole or in part and without penalty or premium, ratably among the Lenders in integral multiples of $5,000,000, upon at least three (3) Business Days’ written notice to the Agent, which notice shall specify, as applicable (a) the aggregate amount of any such reduction and/or (b) the individual amount by which the applicable Borrower Sublimit shall be reduced, provided, however, that (i) the amount of the Aggregate Commitment may not be reduced below the Aggregate Outstanding Credit Exposure and (ii) the Borrower Sublimit of any Borrower may not be reduced below the Borrower Credit Exposure of such Borrower. Any reduction of the Aggregate Commitment under this Section (other than the first sentence hereof) shall reduce ratably the Commitments of all the Lenders.

2.9. Minimum Amount of Each Advance. Each Eurodollar Advance shall be in the minimum amount of $5,000,000 (and in a multiple of $1,000,000 if in excess thereof), and each Floating Rate Advance shall be in the minimum amount of $5,000,000 (and in a multiple of $1,000,000 if in excess thereof); provided, however, that (i) any Floating Rate Advance to a Borrower may be in the amount of the Available Aggregate Commitment and (ii) any Floating Rate Advance to a Borrower may be in the amount equal to the lesser of the Available Aggregate Commitment and the amount by which the Borrower Sublimit of such Borrower exceeds the Borrower Credit Exposure of such Borrower. Each Swingline Loan shall be in an amount that is an integral multiple of $500,000 and not less than $1,000,000.

2.10. Optional Principal Payments. Each Borrower may from time to time pay, without penalty or premium, all outstanding Floating Rate Advances of such Borrower, or any portion of such outstanding Floating Rate Advances, in a minimum aggregate amount of $1,000,000 or any integral multiple of $1,000,000 in excess thereof (or, if less, the remaining outstanding principal amount of such Borrower’s Floating Rate Advances), upon at least one (1) Business Day’s prior notice to the Agent. Each Borrower may from time to time pay, subject to the payment of any funding indemnification amounts required by Section 3.4 but without penalty or premium, all outstanding Eurodollar Advances of such Borrower, or any portion of such outstanding Eurodollar Advances, in a minimum aggregate amount of $1,000,000 or any integral multiple of $1,000,000 in excess thereof (or, if less, the remaining outstanding principal amount of such Borrower’s Eurodollar Advances), upon at least three (3) Business Days’ prior notice to the Agent; provided that no Competitive Loan may be prepaid without the consent of the applicable Lender. Each Borrower may from time to time pay, without penalty or premium, any outstanding Swingline Loan upon giving notice thereof to the Swingline Lender not later than 12:00 noon, New York City time, on the date of prepayment. Any optional payment of Advances (other than Competitive Loans and Swingline Loans) under this Section shall be applied ratably to the Advances (other than Competitive Loans and Swingline Loans) of all the Lenders.

2.11. Method of Selecting Types and Interest Periods for New Revolving Advances; Funding of Loans. The applicable Borrower shall select the Type of each Revolving Advance and, in the case of each Eurodollar Advance, the Interest Period applicable thereto; provided that there shall be no more than five (5) Interest Periods in effect with respect to all of the Revolving Loans of any single Borrower at any time, unless such limit has been waived by the Agent in its sole discretion. The applicable Borrower shall give the Agent irrevocable notice (a “Borrowing Notice”) not later than 11:00 a.m. (New York time) on the Borrowing Date of each Floating Rate Advance or on the third Business Day before the Borrowing Date for each Eurodollar Advance, specifying:

(i)

the Borrower requesting such Advance,

(ii)

the Borrowing Date, which shall be a Business Day, of such Advance,

(iii)

the aggregate amount of such Advance,

(iv)

the Type of Advance selected, and

(v)

in the case of each Eurodollar Advance, the Interest Period applicable thereto.

The Agent shall provide written notice of each request for borrowing under this Section 2.11 by 11:00 a.m. (New York time) (or, if later, within one hour after receipt of the applicable Borrowing Notice from such Borrower) on the Borrowing Date for each Floating Rate Advance or on the third Business Day prior to the Borrowing Date for each Eurodollar Advance, as applicable. Not later than 1:00 p.m. (New York time) on each Borrowing Date, each Lender shall make available its Revolving Loan or Revolving Loans in Federal or other funds immediately available in New York to the Agent at its address specified pursuant to Article XIII. The Agent will promptly make the funds so received from the Lenders available to such Borrower at the Agent’s aforesaid address.

2.12. Conversion and Continuation of Outstanding Revolving Advances; No Conversion or Continuation of Eurodollar Advances After Default. Floating Rate Advances shall continue as Floating Rate Advances unless and until such Floating Rate Advances are converted into Eurodollar Advances pursuant to this Section 2.12 or are repaid in accordance with Section 2.10. Each Eurodollar Advance shall continue as a Eurodollar Advance until the end of the then applicable Interest Period therefor, at which time such Eurodollar Advance shall be automatically converted into a Eurodollar Advance with an Interest Period of 30 days (unless such conversion would otherwise be prohibited hereunder, in which case such Eurodollar Advance shall be converted into a Floating Rate Advance) unless (x) such Eurodollar Advance is or was repaid in accordance with Section 2.10 or (y) the applicable Borrower shall have given the Agent a Conversion/Continuation Notice (as defined below) requesting that, at the end of such Interest Period, such Eurodollar Advance either continue as a Eurodollar Advance for the same or another Interest Period or be converted to a Floating Rate Advance. Subject to the terms of Section 2.9, a Borrower may elect from time to time to convert all or any part of an Advance of any Type into any other Type or Types of Advances; provided that any conversion of any Eurodollar Advance shall be made on, and only on, the last day of the Interest Period applicable thereto. Notwithstanding anything to the contrary contained in this Section 2.12, during the continuance of a Default with respect to a Borrower, the Agent may (or shall at the direction of the Required Lenders), by notice to such Borrower, declare that no Advance of such Borrower may be made, converted or continued as a Eurodollar Advance. The applicable Borrower shall give the Agent irrevocable notice (a “Conversion/Continuation Notice”) of each conversion of a Floating Rate Advance to a Eurodollar Advance, continuation of a Eurodollar Advance, or conversion of a Eurodollar Advance to a Floating Rate Advance not later than 11:00 a.m. (New York time) at least three (3) Business Days prior to the date of the requested conversion or continuation, specifying:

(i)

the requested date, which shall be a Business Day, of such conversion or continuation,

(ii)

the aggregate amount and Type of the Advance to be converted or continued, and

(iii)

the amount of the Advance to be converted into or continued as a Eurodollar Advance and the duration of the Interest Period applicable thereto.

This Section shall not apply to Competitive Loans and Swingline Loans, which may not be converted or continued.

2.13. Interest Rates, etc. Each Floating Rate Advance shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Advance is made, to, but excluding, the date it is paid or is converted into a Eurodollar Advance pursuant to Section 2.12, as applicable, at a rate per annum equal to the Floating Rate applicable to such Borrower for such day. Each Swingline Loan shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Loan is made to but excluding the date it is paid, at a rate per annum equal to the Floating Rate applicable to such Borrower for such day. Changes in the rate of interest on that portion of any Advance maintained as a Floating Rate Advance and on any Swingline Loan will take effect simultaneously with each change in the Alternate Base Rate. Each Eurodollar Advance shall bear interest on the

outstanding principal amount thereof from and including the first day of each Interest Period applicable thereto to (but not including) the earlier of the last day of such Interest Period or the date it is paid in accordance with Section 2.10, at the applicable Eurodollar Rate as determined by the Agent as applicable to such Borrower’s Eurodollar Advance based upon the applicable Borrower’s selections under Sections 2.11 and 2.12 and otherwise in accordance with the terms hereof. Each Fixed Rate Advance shall bear interest at the Fixed Rate applicable thereto.

2.14. Rates Applicable After Default. Notwithstanding the foregoing, if any principal of any Loan is not paid when due, or if any interest on any Loan or any fee or other amount payable by any Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, commencing on the day after such amount shall have become due in the case of principal and on the second Business Day after such amount shall have become due in the case of other amounts, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% per annum plus the rate otherwise applicable to such Loan as provided in Section 2.13 or (ii) in the case of any other amount, 2% per annum plus the rate applicable to Floating Rate Advances as provided in Section 2.13.

2.15. 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 to which such Obligations are owing. 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. The Agent is hereby authorized to charge the account of any Borrower maintained with JPMCB for each payment of principal, interest and fees owed by such Borrower as it becomes due hereunder.

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 each Borrower to such Lender resulting from each Loan made by such Lender to such 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 each 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 each Borrower to each Lender hereunder, (c) the effective date and amount of each Assignment and Assumption delivered to and accepted by it pursuant to Section 12.1 and the parties thereto, (d) the amount of any sum received by the Agent hereunder from each Borrower and each Lender’s share thereof, and (e) all other appropriate debits and credits as provided in this Agreement, including 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 such 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 applicable 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 12.1) 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. Each 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 such Borrower, it being understood that the foregoing authorization is specifically intended to allow Borrowing Notices and Conversion/Continuation Notices to be given telephonically. Each 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 and Fee 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 each Fixed Rate Loan shall be payable on the last day of the Interest Period applicable to the Advance of which such Loan is a part and, in the case of a Fixed Rate Advance with an Interest Period of more than 90 days’ duration (unless otherwise specified in the applicable Competitive Bid Request), each day prior to the last day of such Interest Period that occurs at intervals of 90 days’ duration after the first day of such Interest Period, and any other dates that are specified in the applicable Competitive Bid Request as dates for payment of interest with respect to such Advance. Interest accrued on each Swingline Loan shall be payable in arrears on the day that such Loan is repaid or is required to be paid. 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, Fixed Rate Loans and fees hereunder shall be calculated for actual days elapsed on the basis of a 360-day year. Interest on Floating Rate Advances and Swingline Loans 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, any fees 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, fees 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 Aggregate Commitment or Borrower Sublimit reduction notice, Borrowing Notice, Conversion/Continuation Notice, and repayment notice received by it hereunder. The Agent will notify the applicable Borrower and each Lender of the interest rate applicable to each Eurodollar Advance promptly upon determination of such interest rate and will give each Borrower and each Lender prompt notice of each change in the Alternate Base 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 Borrowers 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 applicable Borrower or a Lender, as the case may be, notifies the Agent prior to the date 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 any payment under Section 2.6(e) or (ii) in the case of a Borrower, a payment of principal, interest or fees 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 such 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 a Borrower, the interest rate applicable to the relevant Loan.

2.22. Replacement of Lender. If (x) any Borrower is required pursuant to Section 3.1, 3.2 or 3.5 to make any additional payment to any Lender, (y) 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, or (z) any Lender is a Defaulting Lender, the Borrowers may elect, if (in the case of clause (x) or (y) above) such amounts continue to be charged or such suspension is still effective, to terminate or replace the Commitment of such Affected Lender (as defined below), or if (I) any Lender invokes Section 9.2 or (II) any Lender has advised that it will not consent to any waiver or amendment of this Agreement that requires the approval of all the Lenders and upon the replacement of any such non-consenting Lender such approval shall be obtained (any Lender subject to any of the foregoing clauses (x), (y), (z), (I) or (II) being an “Affected Lender”), the Borrowers may elect to replace the Commitment of such Affected Lender; provided in each of the foregoing cases that no Default or Unmatured Default shall have occurred and be continuing at the time of such termination or replacement, and provided further that, concurrently with such termination or replacement, (i) if the Affected Lender is being replaced, another bank or other entity which is reasonably satisfactory to the Borrowers and the Agent shall agree, as of such date, to purchase for cash at face amount the Outstanding Credit Exposure of the Affected Lender pursuant to an Assignment and Assumption 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 as of such date and to comply with the requirements of Section 12.1 applicable to assignments, (ii) each Borrower shall pay to such Affected Lender in immediately available funds on the day of termination or replacement (A) all interest, fees and other amounts then accrued but unpaid to such Affected Lender by such Borrower hereunder to and including the date of such replacement, including 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 replacement under Section 3.4 had the Loans of such Affected Lender been prepaid on such date rather than sold to the replacement Lender, in each case to the extent not paid by the purchasing lender and (iii) if the Affected Lender is being terminated, each Borrower shall pay to such Affected Lender all Obligations due from such Borrower to such Affected Lender (including the amounts described in the immediately preceding clauses (i) and (ii) plus the outstanding principal balance of such Affected Lender’s Advances and the amount of such Lender’s funded participations in unreimbursed LC Disbursements). Notwithstanding the foregoing, the Borrowers may not terminate the Commitment of an Affected Lender if, after giving effect to such termination, (x) the Aggregate Outstanding Credit Exposure would exceed the Aggregate Commitment, or (y) the Borrower Credit Exposure of any Borrower would exceed the Borrower Sublimit of such Borrower.

2.23. Extension of Borrowing Maturity Dates. The Borrowing Subsidiary may, by notice (a “Maturity Date Extension Request”) to the Agent (which shall promptly deliver a copy to each of the Lenders) given not less than 45 days and not more than 60 days prior to its then-current Maturity Date (the “Existing Maturity Date”), request an extension of the Existing Maturity Date to a date not more than 364 days after the Existing Maturity Date but in no event after the Commitment Termination Date. Each Lender shall, by notice to the Borrowing Subsidiary, the Company and the Agent given not later than the 20^th day after the date of the Agent’s receipt of such Maturity Date Extension Request, advise the Borrowing Subsidiary and the Company whether or not it agrees to the requested extension. Any Lender that has not so advised the Borrowing Subsidiary, the Company and the Agent by such day shall be deemed to have declined to agree to such extension. If Lenders constituting the Required Lenders shall have agreed to a Maturity Date Extension Request, then the Existing Maturity Date shall, as to

all the Lenders, be extended to the date specified in the Maturity Date Extension Request (which shall be not more than 364 days after the Existing Maturity Date); provided, that upon its receipt of the necessary approvals from the Missouri Public Service Commission authorizing the Borrowing Subsidiary to borrow hereunder through the Commitment Termination Date, then upon written notice thereof to the Agent and satisfaction of the conditions set forth in the following sentence, the Maturity Date for the Borrowing Subsidiary shall automatically be extended to the Commitment Termination Date without the consent or approval of any Lender; provided, further, the Borrowing Subsidiary’s Maturity Date shall in no event be extended beyond the Commitment Termination Date. Notwithstanding the foregoing, no extension of the Borrowing Subsidiary’s Maturity Date pursuant to this paragraph shall become effective unless (i) the Agent shall have received documents consistent with those delivered with respect to the Borrowing Subsidiary under Sections 4.1.5 through 4.1.7, giving effect to such extension, (ii) on the Existing Maturity Date, the conditions set forth in Sections 4.2.1 and 4.2.2 shall be satisfied with respect to the Borrowing Subsidiary (with all references in Sections 5.5 and 5.7 to “the Closing Date” being deemed to be references to such Existing Maturity Date) and (iii) if the date specified in the Maturity Date Extension Request is later than March 31, 2012, (x) the Borrowing Subsidiary shall have obtained a FERC Order authorizing the incurrence of short-term indebtedness by the Borrowing Subsidiary in an aggregate principal amount outstanding at least equal to its Borrower Sublimit as in effect at such time, which authorization shall not terminate on or prior to the date specified in the Maturity Date Extension Request, or (y) the Borrowing Subsidiary shall have received the necessary approvals from the Missouri Public Service Commission authorizing the Borrowing Subsidiary to borrow hereunder through the date specified in the Maturity Date Extension Request, and (iv) the Agent shall have received a certificate to the effect as set forth above in this proviso dated such date and executed by the chief financial officer, the controller or the treasurer of the Borrowing Subsidiary.

2.24. Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply:

(i)

Facility Fees shall cease to accrue on the unused portion of such Defaulting Lender’s Commitment.

(ii)

The Commitment and Outstanding Credit Exposure of such Defaulting Lender shall not be included in determining whether the Required Lenders or other requisite Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 8.2); provided that any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender shall require the consent of such Defaulting Lender (in such case, to the extent such Defaulting Lender is an affected Lender).

(iii)

Unless a Default or an Unmatured Default shall have occurred and be continuing, all or any part of such Defaulting Lender’s Swingline Exposure and LC Exposure shall be reallocated among the non-Defaulting Lenders in accordance with their Pro Rata Shares of the Aggregate Commitment, but only to the extent the sum of all non-Defaulting Lenders’ Outstanding Credit Exposures plus such Defaulting Lender’s Swingline Exposure and LC Exposure does not exceed the total of all non-Defaulting Lenders’ Commitments.

(iv)

If the LC Exposure of such Defaulting Lender is reallocated pursuant to subparagraph (iii) above, then the LC Participation Fees payable to the Lenders pursuant to Section 2.8.2 shall be adjusted in accordance with such reallocation.

(v)

If the reallocation described in clause (ii) above cannot, or can only partially, be effected, each Borrower shall within one Business Day following notice by the Agent (x) first, prepay the portion of the Swingline Exposure attributable to Swingline Loans made to such Borrower and (y) second, cash collateralize for the benefit of the Issuing Banks such Borrower’s obligations corresponding to the portion of such Defaulting Lender’s LC Exposure that is attributable to Letters of Credit issued for the account of such Borrower (in each case, as determined after giving effect to any partial reallocation pursuant to clause (iii) above) in accordance with the procedures set forth in Section 2.6(i) for so long as such LC Exposure is outstanding.

(vi)

If a Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to clause (v) above, such Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.8.2 with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized.

(vii)

The Agent shall adjust the allocation of payments hereunder to ensure that a Defaulting Lender does not receive payment in respect of any Loan or LC Disbursement that it did not fund or to reflect any of the actions or adjustments referred to in this Section 2.24.

If (i) a Bankruptcy Event with respect to the parent company of any Lender shall occur following the date hereof and for so long as such event shall continue or (ii) the Swingline Lender or any Issuing Bank shall have a good faith belief that any Lender has defaulted in fulfilling its obligations under one or more other agreements in which such Lender commits to extend credit, the Swingline Lender shall not be required to fund any Swingline Loan and such Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless the Swingline Lender or such Issuing Bank, as the case may be, shall have entered into arrangements with the applicable Borrower or such Lender reasonably satisfactory to the Swingline Lender or such Issuing Bank, as the case may be, to mitigate the risk to it in respect of such Lender failing to satisfy its participating interest therein.

In the event that the Agent, each Borrower, the Swingline Lender and each Issuing Bank agree that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the Swingline Exposure and LC Exposure of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment and on such date such Lender shall purchase at par such of the Loans (other than Competitive Loans and Swingline Loans) and participations in LC Disbursements of the other Lenders as the Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Pro Rata Share.

Except as expressly provided in this Section 2.24 in connection with the obligations of the Swingline Lender or the Issuing Banks, the obligation of each Lender, Issuing Bank and Swingline Lender to fund the full amount of its Commitment and to make Loans, Advances and other extensions of credit hereunder shall not be released or diminished in any respect by any other Lender becoming a Defaulting Lender.

2.25. Commitment Increases. (a) The Borrowers may from time to time (and more than one time), by written notice to the Agent (which shall promptly deliver a copy to each of the Lenders), executed by the Borrowers and one or more financial institutions (any such financial institution referred to in this Section being called an “Augmenting Lender”), which may include any Lender, cause new Commitments to be extended by the Augmenting Lenders or cause the existing Commitments of the Augmenting Lenders to be increased, as the case may be (the aggregate amount of such increase for all Augmenting Lenders on any single occasion being referred to as a “Commitment Increase”), in an amount for each Augmenting Lender set forth in such notice; provided that (i) the amount of each Commitment Increase shall be not less than $10,000,000, except to the extent necessary to utilize the remaining unused amount of increase permitted under this Section 2.25(a) and (ii) the Aggregate Commitment shall not exceed $1,000,000,000 after giving effect to the effectiveness of any Commitment Increase. Each Augmenting Lender (if not then a Lender) shall be subject to the approval of the Agent, each Issuing Bank and the Swingline Lender (which approval shall not be unreasonably withheld) and shall not be subject to the approval of any other Lenders, and the Company and each Augmenting Lender shall execute all such documentation as the Agent shall reasonably specify to evidence the Commitment of such Augmenting Lender and/or its status as a Lender hereunder (such documentation in respect of any Commitment Increase together with the notice of such Commitment Increase being referred to collectively as the “Commitment Increase Amendment” in respect of such Commitment Increase).

(b) Upon each Commitment Increase pursuant to this Section, (i) each Lender immediately prior to such increase will automatically and without further act be deemed to have assigned to each Augmenting Lender providing a portion of such Commitment Increase, and each such Augmenting Lender will automatically and without further act be deemed to have assumed, a portion of such Lender’s participations hereunder in outstanding Letters of Credit such that, after giving effect to such Commitment Increase and each such deemed assignment and assumption of participations, the percentage of the aggregate outstanding participations hereunder in Swingline Loans and Letters of Credit held by each Lender (including each such Augmenting Lender) will (subject to Section 2.24) equal such Lender’s Pro Rata Share and (ii) if, on the date of such Commitment Increase, there are any Revolving Loans outstanding, the parties hereto shall, at the request of the Agent, take actions agreed upon by the Agent and the Company that will result, within a period acceptable to the Agent and the Company, in the outstanding Revolving Loans being held by the Lenders ratably in accordance with their Commitments. In determining the actions to be taken (which may include the prepayment and reborrowing of all or a portion of such Revolving Loans and/or the making of Revolving Loans on a non-pro-rata basis by Augmenting Lenders for the balance of Interest Periods in progress and at rates reflecting the Eurodollar Base Rate at the time for loans of such duration), the Agent and the Lenders will endeavor to minimize breakage costs for which the Borrowers must compensate the Lenders to the extent practicable without undue complexity or administrative burdens on the Agent or the Lenders. The Agent and the Lenders hereby agree that the minimum borrowing, pro rata borrowing and pro rata payment requirements contained elsewhere in this Agreement shall not apply to the transactions effected pursuant to the immediately preceding sentence.

(c) Commitment Increases and new Commitments created pursuant to this Section 2.25 shall become effective on the date specified in the notice delivered by the Company pursuant to the first sentence of paragraph (a) above or on such other date as agreed upon by the Company, the Agent and the applicable Augmenting Lenders.

(d) Notwithstanding the foregoing, no increase in the Commitments (or in any Commitment of any Lender) or addition of an Augmenting Lender shall become effective under this Section unless (i) on the date of such increase, the conditions set forth in Section 4.2 (it being understood and agreed that (A) all references to “Credit Extension Date” therein shall be deemed to refer to the date of such Commitment Increase and (B) all references to the “Closing Date” in Sections 5.5 and 5.7 shall be deemed to refer to the date of such Commitment Increase) shall be satisfied as of such date (as though the effectiveness of such increase were a Credit Extension) and the Agent shall have received a certificate to that effect dated such date and executed by an Authorized Officer of the Company, and (ii) the actions referred to in paragraph (b)(ii) of this Section 2.25 shall have been agreed upon by the Agent and the Company (provided, however, that the prepayment and reborrowing on the date of such Commitment Increase of all Revolving Loans then outstanding shall be deemed to satisfy the condition specified in this clause (ii)).

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, Eurodollar Loans or Fixed Rate Loans or reduces any amount receivable by any Lender or any applicable Lending Installation in connection with its Commitment, Eurodollar Loans or Fixed Rate Loans, or requires any Lender or any applicable Lending Installation to make any payment calculated by reference to the amount of Commitment, Eurodollar Loans or Fixed Rate 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, Eurodollar Loans or Fixed Rate Loans or to reduce the return received by such Lender or applicable Lending Installation in connection with such Commitment, Eurodollar Loans or Fixed Rate Loans, then, within 15 days of demand, accompanied by the written statement required by Section 3.6, by such Lender, the Borrowers 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 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 Borrowers shall pay such Lender the amount applicable to such Borrower 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 Outstanding Credit Exposure 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 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 Basel 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 or a Fixed Rate Loan 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, a Fixed Rate Loan is not made or a Floating Rate Advance is not converted into a Eurodollar Advance on the date specified by the applicable Borrower for any reason other than default by the Lenders, a Eurodollar Advance or Fixed Rate Loan is not prepaid on the date specified by such Borrower for any reason, or a Eurodollar Advance is prepaid by such Borrower without such Borrower providing at least three (3) Business Days’ prior notice to the Agent for any reason, such Borrower will severally and not jointly with the other Borrower indemnify each Lender for any loss or cost incurred by it resulting therefrom, including any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance or Fixed Rate Loan as determined by such Lender (if and to the extent such Lender, in its sole discretion, elects to impose such a charge), excluding loss of margin on the principal amount subject thereto. Notwithstanding the foregoing, a Defaulting Lender required to assign its Loans pursuant to Section 2.24 shall not be entitled to compensation under this Section 3.4 in connection with any such assignment.

3.5. Taxes.

(i)

All payments by any 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 unless required by law. If a Borrower or the Agent is required by law to deduct any Taxes from or in respect of any sum payable hereunder, (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) such Borrower shall make such deductions, (c) such Borrower shall pay the full amount deducted to the relevant taxing authority in accordance with applicable law and (d) such 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 Borrowers shall 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 Borrowers shall indemnify the Agent and each Lender for the full amount of Taxes or Other Taxes (including 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 expenses) arising therefrom or with respect thereto. Payments due under this Section 3.5(iii) 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 shall deliver to the Agent and the applicable Borrower, 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), two duly completed copies of:

(a)

in the case of a Lender that is a U.S. Person, IRS Form W-9,

(b)

in the case of a Non-U.S. Lender claiming the benefits of an income tax treaty to which the United States is a party (1) with respect to payments of interest under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding tax pursuant to the “interest” article of such tax treaty and (2) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from U.S. federal withholding tax pursuant to the “business profits” or “other income” article of such tax treaty,

(c)

in the case of a Non-U.S. Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, both (1) IRS Form W-8BEN and (2) a certificate to the effect that such Lender is not (A) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, (C) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code or (D) conducting a trade or business in the United States with which the relevant interest payments are effectively connected,

(d)

in the case of a Non-U.S. Lender for which payments under any Loan Document constitute income that is effectively connected with such Non-U.S. Lender’s conduct of a trade or business in the United States, IRS Form W-8ECI,

(e)

in the case of a Non-U.S. Lender that is not the beneficial owner of payments made under any Loan Document (including a partnership or a participating Lender) (1) an IRS Form W-8IMY on behalf of itself and (2) the relevant forms described in parts (a), (b), (c), (d) and (f) of this Section 3.5(iv) that would be required of each such beneficial owner, if such beneficial owner were a Lender; provided, however, that if the Lender is a partnership and one or more of its partners are claiming the exemption for portfolio interest under Section 881(c) of the Code, such Lender may certify that the requirements for such exemption are met on behalf of such partners or

(f)

any other form prescribed by law as a basis for claiming exemption from, or a reduction of, U.S. federal withholding tax, together with any other documentation necessary to enable the applicable Borrower or the Agent to determine the amount of tax (if any) required by law to be withheld.

Each Lender shall deliver to each of the Borrowers 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 Borrowers or the Agent. Notwithstanding the foregoing in this Section 3.5(iv), no Lender shall have any obligation under this Section 3.5(iv) if an event (including 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 Borrowers and the Agent that it is not capable of receiving payments without any deduction or withholding of U.S. federal income tax.

(v)

For any period during which a Lender has failed to provide the appropriate forms contemplated by Section 3.5(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 Lender became a party to this Agreement (or, in the case of a 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 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 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 Section 3.5(iv) above, each Borrower shall take such steps as such Lender shall reasonably request to assist such Lender to recover such Taxes.

(vi)

If the IRS 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(vi) shall survive the payment of the

Obligations and termination of this Agreement until the later of (i) the expiration of the statute of limitations (taking into account all extensions) for the assessment of such tax or (ii) the conclusion of any audit with respect to such tax.

(vii)

If a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Agent as may be necessary for the Agent to comply with its obligations under FATCA, to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment.

3.6. Lender Statements; Survival of Indemnity. Each Lender shall deliver a written statement of such Lender to the applicable Borrower (with a copy to the Agent and each applicable Borrower) 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 such Borrower in the absence of manifest error, and upon reasonable request of such Borrower, such Lender shall promptly provide supporting documentation describing and/or evidencing 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 within seven (7) Business Days after receipt by the applicable Borrower of such written statement, unless subject to a good faith dispute by such Borrower, notice and details of which was provided to the affected Lender prior to such due date. The obligations of each 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 Borrowers shall not be responsible for any reimbursement of any such amount under Section 3.1, 3.2, 3.4 or 3.5 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 Borrowers 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 Borrowers’ rights under Section 2.22 to replace a Lender.

3.8. Allocation of Amounts Payable Among Borrowers. Each amount payable by “the Borrowers” under this Article shall be an obligation of, and shall be discharged (a) to the extent arising out of acts, events and circumstances related to a particular Borrower, by such Borrower and (b) otherwise, by both Borrowers, with each Borrower being severally liable for such Borrower’s Contribution Percentage of such amount, provided that the Company agrees that, if the Borrowing Subsidiary shall fail to pay any amount owed by it under clause (b) of this Section after a demand shall have been made by the Person to which such amount is owed, the Company shall promptly pay such amount (the Company hereby irrevocably waiving any defenses that might otherwise be available to it as a guarantor of the obligations of the Borrowing Subsidiary under this Section).

ARTICLE IV

ARTICLE V

REPRESENTATIONS AND WARRANTIES

Each Borrower severally as to such Borrower and, as applicable, its Subsidiaries, and not jointly with the other Borrower or its Subsidiaries, hereby represents and warrants to each Lender, each Issuing Bank and the Agent:

5.1. Existence and Standing. Such 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, other than the failure of any such Borrower to be qualified to transact business in any such jurisdiction to the extent such failure could not reasonably be expected to result in a Material Adverse Effect with respect to such Borrower.

5.2. Authorization and Validity. Such 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 such 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 such Borrower is a party constitute legal, valid and binding obligations of such Borrower enforceable against such 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. Neither the execution and delivery by such 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 such Borrower or any of its Subsidiaries the violation of which is known to, or could reasonably be expected to, have a Material Adverse Effect with respect to such Borrower or (ii) such 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 the New Illinois Credit Agreement, the New Genco Credit Agreement or any indenture or the material provisions of any material instrument or any material agreement to which such Borrower or any of its Subsidiaries is a party or is subject, or by which it, or its Property, is bound, or result in, or require, the creation or imposition of any Lien in, of or on the Property of such Borrower or a Subsidiary pursuant to the terms of, the New Illinois Credit Agreement, the New Genco Credit Agreement or any such indenture, instrument or agreement.

5.4. Financial Statements. The consolidated financial statements of such Borrower, audited by PricewaterhouseCoopers LLP, as of and for the fiscal year ended December 31, 2009, and the unaudited consolidated balance sheets of such Borrower as of March 31, 2010, and June 30, 2010, and the related unaudited statement of income and statement of cash flows for the periods 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 periods ended March 31, 2010, and June 30, 2010, to the absence of footnotes and subject to year-end adjustments) the consolidated financial condition of such Borrower at such dates and the consolidated results of the operations of such Borrower for the periods ended on such dates, were prepared, except in the case of such unaudited statements, 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 such Borrower at such dates and the consolidated results of their operations for the periods then ended. Except as disclosed in the financial statements referred to above or in the notes thereto or on Schedule 5 hereto, neither such Borrower nor any of its Subsidiaries has as of the Closing Date any material contingent liabilities.

5.5. Material Adverse Change. As of the Closing Date, since December 31, 2009, there has been no change in the business, Property, condition (financial or otherwise) or results of operations of such Borrower and its Subsidiaries (other than any Project Finance Subsidiary) that could reasonably be expected to have a Material Adverse Effect with respect to such Borrower, except for the Disclosed Matters.

5.6. Taxes. Such Borrower and its Subsidiaries have filed all U.S. 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 such 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 IRS has closed audits of, or the statute of limitations has expired for, the U.S. federal income tax returns filed by each Borrower for all periods through the calendar taxable year ending December 31, 2004. The IRS has not closed audits of the U.S. federal income tax returns filed by any 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 with respect to such Borrower and no Liens have been filed with respect to such taxes (other than as permitted pursuant to Section 6.13.2). The charges, accruals and reserves on the books of such Borrower and its Subsidiaries in respect of any taxes or other governmental charges are adequate.

5.7. Litigation and Contingent Obligations. As of the Closing Date, 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 such Borrower or any of its Subsidiaries that could reasonably be expected to have a Material Adverse Effect with respect to such Borrower or that seeks to prevent, enjoin or delay the making of any Loans to such Borrower.

5.8. Subsidiaries. Schedule 1 contains an accurate list of all Subsidiaries of such Borrower as of the Closing Date, setting forth their respective jurisdictions of organization and the percentage of their respective capital stock or other ownership interests owned by such Borrower or other Subsidiaries of such Borrower. As of the Closing Date, all the issued and outstanding shares of capital stock or other ownership interests of such Subsidiaries have been (to the extent such concepts are relevant with respect to such ownership interests) duly authorized and issued and are fully paid and non-assessable.

5.9. ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other ERISA Events that have occurred or are reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect with respect to such Borrower.

5.10. Accuracy of Information. The written information, exhibits or reports (other than budgets, forecasts, projections and forward looking statements (collectively, “Projections”)) with respect to such Borrower furnished to the Agent or to any Lender in connection with the negotiation of, or compliance with, the Loan Documents as of the date prepared, and the information with respect to such Borrower communicated by responsible officers of such Borrower to attendees generally at any meeting or conference call of Lenders or prospective Lenders (including any due diligence meeting or call) scheduled or arranged by the Agent as of

the date communicated, do not, when taken as a whole, contain any material misstatement of fact or omit to state a material fact or any fact necessary to make the statements contained therein not materially misleading. The Projections with respect to such Borrower furnished to the Agent or to any Lender in connection with the negotiation of, or compliance with, the Loan Documents as of the date furnished have been prepared in good faith based upon assumptions believed by such Borrower to be reasonable at the time such Projections were prepared.

5.11. Regulation U. Neither such Borrower nor any of its Subsidiaries is engaged principally, or as one of its important activities, in the business of extending credit for the purpose, whether immediate, incidental or ultimate, of buying or carrying margin stock (as defined in Regulation U), and after applying the proceeds of each Advance, margin stock (as defined in Regulation U) will constitute less than 25% of the value of those assets of such Borrower and its Subsidiaries that are subject to any limitation on sale, pledge, or any other restriction hereunder.

5.12. Material Agreements. Neither such Borrower nor any of its Subsidiaries is in default in the performance, observance or fulfillment of any of the obligations, covenants or conditions contained in any agreement or instrument (other than any of the foregoing evidencing or governing Indebtedness) to which it is a party, which default could reasonably be expected to have a Material Adverse Effect with respect to such Borrower.

5.13. Compliance With Laws. Except for the Disclosed Matters, such Borrower and its Subsidiaries have complied with all applicable statutes, rules, regulations, orders and restrictions of any domestic or foreign government or any instrumentality or agency thereof having jurisdiction over the conduct of their respective businesses or the ownership of their respective Property, non-compliance with which could reasonably be expected to result in a Material Adverse Effect with respect to such Borrower.

5.14. Ownership of Properties. Such Borrower and its Subsidiaries have good title to or rights to use (except for minor defects in title that do not interfere with their ability to conduct their business as currently conducted or to utilize such properties for the intended purposes), free of all Liens other than those permitted by Section 6.13, all of the assets material to the business of such Borrower and its Subsidiaries, taken as a whole, except where the failure to have such title or right could not reasonably be expected to result in a Material Adverse Effect with respect to such Borrower.

5.15. Plan Assets; Prohibited Transactions. Such Borrower is not an entity deemed to hold “plan assets” within the meaning of 29 C.F.R. § 2510.3-101 of an employee benefit plan (as defined in Section 3(3) of ERISA) which is subject to Title I of ERISA or any plan (within the meaning of Section 4975 of the Code), and assuming the accuracy of the representations and warranties made in Section 9.12 and in any assignment made pursuant to Section 12.1, neither the execution of this Agreement nor the making of Loans hereunder gives rise to a prohibited transaction within the meaning of Section 406 of ERISA or Section 4975 of the Code.

5.16. Environmental Matters. In the ordinary course of its business, the officers of such Borrower consider the effect of Environmental Laws on the business of such Borrower and its Subsidiaries, in the course of which they identify and evaluate potential risks and liabilities accruing to such Borrower due to Environmental Laws. On the basis of this consideration, such Borrower has concluded that, other than the Disclosed Matters, there exists no violation of, no actual or contingent liability under, and no requirement under any Environmental Laws that could reasonably be expected to have a Material Adverse Effect with respect to such Borrower. 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 with respect to such Borrower, neither such 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.

5.17. Investment Company Act. Neither such Borrower nor any Subsidiary of such Borrower is an “investment company” or a company “controlled” by an “investment company”, within the meaning of the Investment Company Act of 1940, as amended.

5.18. Federal Energy Regulatory Commission; Authorization. The Company is a “holding company” and the Borrowing Subsidiary is a “public utility”, as such terms are defined in the 2005 Act. The FERC has issued a FERC Order dated March 31, 2010, with respect to the Borrowing Subsidiary, which is in full force and effect, authorizing the incurrence of short-term indebtedness by the Borrowing Subsidiary in an aggregate principal amount outstanding not to exceed its FERC Limit. The authorization under the March 31, 2010 FERC Order expires March 31, 2012. Unless such authorization is no longer required by applicable laws and regulations (and the Agent shall have received confirmation thereof reasonably satisfactory to it), additional authorization from the FERC (or any governmental agency that succeeds to the authority of the FERC) or the Missouri Public Service Commission will be necessary for the Borrowing Subsidiary to obtain any Advances under this Agreement or to incur or issue short-term indebtedness, including Advances extended under this Agreement after March 31, 2012. No regulatory authorizations, approvals, consents, registrations, declarations or filings are required in connection with the borrowings by, and issuances of Letters of Credit for the account of, the Company or the Borrowing Subsidiary hereunder or the performance by each of Company and the Borrowing Subsidiary of its Obligations hereunder and under the other Loan Documents, except as set forth above or where the failure to have obtained, made or maintained any such authorizations, approvals, consents, registrations, declarations or filings could not reasonably be expected to result in a Material Adverse Effect with respect to such Borrower. No authorizations, approvals, consents, registrations, declarations or filings of, by or with any regulatory or governmental agency or body or of, by or with any other third party are required in connection with the execution and delivery by any Borrower of the Loan Documents, the borrowings by, and issuances of Letters of Credit for the account of, any Borrower hereunder or the performance by any Borrower of its Obligations, except as set forth above or where the failure to have obtained, made or maintained any such authorizations, approvals, consents, registrations, declarations or filings could not reasonably be expected to result in a Material Adverse Effect with respect to such Borrower.

5.19. No Default or Unmatured Default. No Default or Unmatured Default has occurred and is continuing with respect to such Borrower.

None of this Agreement, any other Loan Document or any provision hereof or thereof may be waived, amended or modified except, in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by each Borrower, the Agent and the Required Lenders and, in the case of any other Loan Document, pursuant to an agreement or agreements in writing entered into by the Agent and the other party or parties thereto, in each case with the consent of the Required Lenders; provided that (i) any provision of this Agreement or any other Loan Document may be amended by an agreement in writing entered into by each Borrower and the Agent to correct any administrative or other manifest error, omission, defect or inconsistency so long as, in each case, the Lenders shall have received at least seven Business Days’ prior written notice thereof and the Agent shall not have received, within seven Business Days of the date of such notice to the Lenders, a written notice from the Required Lenders stating that the Required Lenders object to such amendment and (ii) no such agreement shall (A) increase the Commitment of any Lender without the written consent of such Lender, (B) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (C) postpone the scheduled maturity date of any Loan or any date for the payment of any interest or fees payable hereunder, or reduce the amount of, waive or

excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (D) change Section 11.2 in a manner that would alter the pro rata sharing of payments required thereby without the written consent of each Lender, (E) change any of the provisions of this Section or the percentage set forth in the definition of the term “Required Lenders” or any other provision of any Loan Document specifying the number or percentage of Lenders required to waive, amend or modify any rights thereunder or make any determination or grant any consent thereunder, without the written consent of each Lender; provided that no such agreement shall amend, modify, extend or otherwise affect the rights or obligations of the Agent, any Issuing Bank or the Swingline Lender without the prior written consent of the Agent, such Issuing Bank or the Swingline Lender, as the case may be.

Notwithstanding the foregoing, any provision of this Agreement may be amended by an agreement in writing entered into by the applicable Borrower, the Required Lenders and the Agent if, by the terms of such agreement, (i) the Commitment of each Lender not consenting to the amendment provided for therein shall terminate upon the effectiveness of such amendment and (ii) upon the effectiveness of such amendment, each Lender not consenting to such amendment shall receive 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, the Agent or the Issuing Banks 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 Credit Extension notwithstanding the existence of a Default or Unmatured Default or the inability of a Borrower to satisfy the conditions precedent to such Credit Extension shall not constitute any waiver or acquiescence. Any single or partial exercise of any such right shall not preclude 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, the Issuing Banks and the Lenders until all of the Obligations have been paid in full.

10.2. Powers. 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 the Issuing Banks, or any obligation to the Lenders or the Issuing Banks to take any action thereunder except any action specifically provided by the Loan Documents to be taken by the Agent.

10.4. No Responsibility for Loans, Recitals, etc. Neither the Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain,

inquire into, or verify (a) any statement, warranty or representation made in connection with any Loan Document or any borrowing hereunder; (b) the performance or observance of any of the covenants or agreements of any obligor under any Loan Document, including any agreement by an obligor to furnish information directly to each Lender and each Issuing Bank; (c) the satisfaction of any condition specified in Article IV, except receipt of items required to be delivered solely to the Agent; (d) the existence or possible existence of any Default or Unmatured Default; (e) the validity, enforceability, effectiveness, sufficiency or genuineness of any Loan Document or any other instrument or writing furnished in connection therewith; (f) the value, sufficiency, creation, perfection or priority of any Lien in any collateral security; or (g) the financial condition of the Borrowers or any guarantor of any of the Obligations or of any of the Borrowers’ or any such guarantor’s respective Subsidiaries. The Agent shall have no duty to disclose to the Lenders or the Issuing Banks information that is not required to be furnished by the Borrowers to the Agent at such time, but is voluntarily furnished by the Borrowers to the Agent (either in its capacity as Agent or in its individual capacity).

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.

The obligations of the Lenders under this Section 10.8 shall survive payment of the Obligations, termination and expiration of the Letters of Credit 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 a 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 Borrowers, the Lenders and the Issuing Banks.

10.10. Rights as a Lender. In the event the Agent is a Lender or an Issuing Bank, the Agent shall have the same rights and powers hereunder and under any other Loan Document with respect to its Commitment and its Credit Extensions as any Lender or any Issuing Bank and may exercise the same as though it were not the Agent, and the term “Lender” or “Lenders” or “Issuing Bank” shall, at any time when the Agent is a Lender or an Issuing Bank, 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 each Borrower or any of its Subsidiaries in which such 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 and each Issuing Bank acknowledges that it has, independently and without reliance upon the Agent, any Arranger or any other Lender or any other Issuing Bank and based on the financial statements prepared by

the Borrowers 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 and each Issuing Bank also acknowledges that it will, independently and without reliance upon the Agent, any 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, the Issuing Banks and the Borrowers, such resignation to be effective upon the appointment of a successor Agent; provided that such successor Agent is a Lender or an Affiliate of a Lender, 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 Borrowers (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 Borrowers and the Lenders, a successor Agent. If no successor Agent shall have been so appointed by the Required Lenders or consented to by the Borrowers 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 Borrowers and the Lenders, a successor Agent. Notwithstanding the previous sentence, the Agent may at any time without the consent of the Borrowers or any Lender or any Issuing Bank, 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 Borrowers 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 $1,000,000,000 (or such lower amount as shall be acceptable to the Company). 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 Arrangers Fees. Each Borrower severally and not jointly agrees to pay to the Agent and each Arranger, for their respective accounts, the agent and arrangers fees agreed to by such Borrowers, the Agent and such Arranger pursuant to and in accordance with the letter agreements dated July 29, 2010, or as otherwise agreed from time to time.

10.14. Delegation to Affiliates. The Borrowers, the Lenders and the Issuing Banks agree that the Agent may delegate any of its duties under this Agreement to any of its Affiliates (it being agreed that the Agent will remain responsible for the performance of all such duties). 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 Lenders identified in this Agreement as “Syndication Agents” 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 a Borrower becomes insolvent, however evidenced, or any Default occurs with respect to a Borrower, 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 or any Issuing Bank to or for the credit or account of such Borrower may be offset and applied toward the payment of the Obligations owing by such Borrower to such Lender or such Issuing Bank, whether or not the Obligations, or any part thereof, shall then be due. Promptly upon the exercise of its right of setoff hereunder, each Lender and Issuing Bank shall deliver written notice thereof to the Agent, and the Agent shall make such notice available to the other Lenders and Issuing Banks.

11.2. Ratable Payments. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements or Swingline Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and Swingline Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements and Swingline Loans of other Lenders to the extent necessary so that the amount of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amounts of principal of and accrued interest on their Loans and participations in LC Disbursements and Swingline Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation

in any of its Loans or participations in LC Disbursements or Swingline Loans to any assignee or participant, other than to either Borrower, any other Subsidiary or any Affiliate of any of the foregoing (as to which the provisions of this paragraph shall apply). Each Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against each Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of any Issuing Bank that issues any Letter of Credit), except that (i) neither Borrower may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Agent and each Lender (and any attempted assignment or transfer by any Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section.

(b) Assignments.

(i)

Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of:

(A) each Borrower; provided that no consent of the Borrowers shall be required (1) for an assignment to a Lender, an Affiliate of a Lender or an Approved Fund and (2) if a Default has occurred and is continuing, for any other assignment;

(B) the Agent;

(D) the Swingline Lender.

(ii)

Assignments shall be subject to the following additional conditions:

(A) except in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Agent) shall not be less than $5,000,000 unless each Borrower and the Agent otherwise consent; provided that no such consent of the Borrowers shall be required if a Default has occurred and is continuing;

(B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement, except that this sentence shall not apply to rights in respect of outstanding Competitive Loans;

(C) the parties to each assignment shall execute and deliver to the Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and

(D) the assignee, if it shall not be a Lender, shall deliver to the Agent an Administrative Questionnaire in which the assignee designates one or more credit contacts to whom all syndicate-level information (which may contain material non-public information about the Borrowers and their Related Parties or their securities) will be made available and who may receive such information in accordance with the assignee’s compliance procedures and applicable law, including Federal, State and foreign securities laws.

(iii)

Subject to acceptance and recording thereof pursuant to paragraph (b)(v) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Article III and Section 9.6).

(iv)

The Agent shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and records of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error and the Borrowers, the Agent, the Issuing Banks 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 any Borrower and, as to entries pertaining to it, any Issuing Bank or Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v)

Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative

Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in this Section and any written consent to such assignment required by this Section, the Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. Each assignee, by its execution and delivery of an Assignment and Assumption, shall be deemed to have represented to the assigning Lender and the Agent that such assignee is an Eligible Assignee.

(i)

Any Lender may, without the consent of either Borrower, the Agent, any Issuing Bank or the Swingline Lender, sell participations to one or more Eligible Assignees (“Participants”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (C) the Borrowers, the Agent, the Issuing Banks, the Swingline Lender and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and (D) without the prior written consent of the Agent, no participation shall be sold to a prospective participant that bears a relationship to any Borrower described in Section 108(e)(4) of the Code. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of this Agreement or any other Loan Document; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 8.2 that affects such Participant or requires the approval of all of the Lenders. Subject to paragraph (c)(ii) of this Section, each Borrower agrees that each Participant shall be entitled to the benefits of Article III to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.1 as though it were a Lender; provided such Participant agrees to be subject to Section 11.2 as though it were a Lender.

(ii)

A Participant shall not be entitled to receive any greater payment under Section 3.1, 3.2 or 3.5 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrowers’ prior written consent. A Participant that would be a Non-U.S. Lender if it were a Lender shall not be entitled to the benefits of Section 3.5 unless each Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 3.5 as though it were a Lender.

(iii)

Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrowers, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under any Loan Document (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Loans, Letters of Credit or its other obligations under any Loan Document) except to the extent that such disclosure is necessary to establish that such Commitment, Loan, Letter of Credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each person whose name is recorded in the Participant Register as the owner of such participation for all purposes of any Loan Document notwithstanding any notice to the contrary.

(d) Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, 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.
