ALLIANT ENERGY CORPORATION, a Wisconsin corporation (the “Borrower”),

the banks (the “Banks”) listed on the signature pages hereof and the other Lenders (as hereinafter defined) from time to time party hereto, and

BANK ONE, NA (“Bank One”), as administrative agent (the “Agent”) for the Lenders hereunder and as the issuer of Letters of Credit (as hereinafter defined) (the “LC Issuing Bank”).

The Borrower has requested that the Banks and LC Issuing Bank provide certain Extensions of Credit (as hereinafter defined) to the Borrower.

The Banks and LC Issuing Bank have agreed to make such Extensions of Credit subject to the terms and conditions of this Agreement.

  the rate of interest announced publicly by Bank One or its corporate parent, Bank One Corporation, from time to time, as its corporate base rate or prime rate of interest; and

  1/2 of one percent per annum above the Federal Funds Rate.

    (i)        in the case of each Base Rate Advance, a rate per annum equal at all times to the sum of the Alternate Base Rate in effect from time to time plus the Applicable Margin in effect from time to time; and

    (ii)        in the case of each Eurodollar Rate Advance comprising part of the same Borrowing, a rate per annum during each Interest Period equal at all times to the sum of the Eurodollar Rate for such Interest Period plus the Applicable Margin in effect from time to time during such Interest Period.

the Borrower may not select any Interest Period that ends after the Termination Date;

Interest Periods commencing on the same date for  Advances comprising part of the same  Borrowing shall be of the same duration; and

whenever the last day of any Interest Period would otherwise occur on a day other than a Business Day, the last day of such Interest Period shall be extended to occur on the next succeeding Business Day, provided, in the case of any Interest Period for a Eurodollar Rate Advance, that if such extension would cause the last day of such Interest Period to occur in the next following calendar month, the last day of such Interest Period shall occur on the next preceding Business Day.

recourse to the named obligor with respect to such Debt (the “Debtor”) for amounts limited to the cash flow or net cash flow (other than historic cash flow or historic net cash flow) from the asset; and

recourse to the Debtor for the purpose only of enabling amounts to be claimed in respect of such Debt in an enforcement of any security interest or lien given by the Debtor over the asset or the income, cash flow or other proceeds deriving from the asset (or given by any shareholder or the like in the Debtor over its shares or like interest in the capital of the Debtor) to secure the Debt, but only if the extent of the recourse to the Debtor is limited solely to the amount of any recoveries made on any such enforcement;

recourse to the Debtor generally or indirectly to any Affiliate of the Debtor, under any form of assurance, undertaking or support, which recourse is limited to a claim for damages (other than liquidated damages and damages required to be calculated in a specified way) for a breach of an obligation (other than a payment obligation or an obligation to comply or to procure compliance by another with any financial ratios or other tests of financial condition) by the Person against which such recourse is available; and

recourse to the Debtor, if such Debtor’s assets are limited to the asset so acquired, developed, owned or operated and other assets used in connection with or produced by the operation of the asset so acquired, developed, owned or operated.

The Advances.

Each Lender severally agrees, on the terms and conditions hereinafter set forth, to make Advances to the Borrower from time to time, during the period from and including the date hereof, to and up to, but excluding, the Revolving Commitment Termination Date, in an aggregate outstanding amount not to exceed at any time such Lender’s Available Commitment. Each Borrowing shall be in an aggregate amount not less than $5,000,000 (or, if lower, the amount of the Available Commitments) or an integral multiple of $1,000,000 in excess thereof and shall consist of Advances of the same Type made on the same day by the Lenders ratably according to their respective Percentages. Within the limits of each Lender’s Commitment and as hereinabove and hereinafter provided, the Borrower may request Borrowings hereunder, and repay or prepay Advances pursuant to Section 2.11 and utilize the resulting increase in the Available Commitments for further Extensions of Credit in accordance with the terms hereof.

In no event shall the Borrower be entitled to request or receive any Borrowings that would cause the Outstanding Credits to exceed the Commitments.

Making the Advances.

Each Borrowing shall be made on notice, given not later than 11:00 a.m. (i) on the third Business Day prior to the date of the proposed Borrowing, in the case of a Borrowing comprised of Eurodollar Rate Advances and (ii) on the date of the proposed Borrowing, in the case of a Borrowing comprised of Base Rate Advances, in each case by the Borrower to the Agent, which shall give to each Lender prompt notice thereof by telecopier, telex or cable. Each such notice of a Borrowing (a “Notice of Borrowing”) shall be by telecopier, telex or cable, in substantially the form of Exhibit 2.02(a) hereto, specifying therein the requested (A) date of such Borrowing, (B) Type of Advances comprising such Borrowing, (C) aggregate amount of such Borrowing and (D) in the case of a Borrowing comprised of Eurodollar Rate Advances, the initial Interest Period for each such Advance. Each Lender shall, before (x) 12:00 noon on the date of such Borrowing, in the case of a Borrowing comprised of Eurodollar Rate Advances, and (y) 1:00 p.m. on the date of such Borrowing, in the case of a Borrowing comprised of Base Rate Advances, make available for the account of its Applicable Lending Office to the Agent at its address referred to in Section 8.02, in same day funds, such Lender’s ratable portion of such Borrowing. After the Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Agent will promptly make such funds available to the Borrower at the Agent’s aforesaid address.

Each Notice of Borrowing shall be irrevocable and binding on the Borrower. In the case of any Borrowing which the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Eurodollar Rate Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date.

Unless the Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not make available to the Agent such Lender’s Advance as part of such Borrowing, the Agent may assume that such Lender has made such Advance available to the Agent on the date of such Borrowing in accordance with subsection (a) of this Section 2.02 and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such Advance available to the Agent, such Lender and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount, together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement.

The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Borrowing.

Letters of Credit.

Subject to the terms and conditions hereof, each Letter of Credit shall be issued (or the stated maturity thereof extended or terms thereof modified or amended) on not less than two Business Days’ prior notice thereof by delivery of a Request for Issuance to the Agent (which shall promptly distribute copies thereof to the Lenders) and the LC Issuing Bank. Each Request for Issuance shall specify (i) the date (which shall be a Business Day) of issuance of such Letter of Credit (or the date of effectiveness of such extension, modification or amendment) and the stated expiry date thereof (which shall be no later than the Revolving Commitment Termination Date), (ii) the proposed stated amount of such Letter of Credit (which shall not be less than $1,000,000), (iii) the name and address of the beneficiary of such Letter of Credit and (iv) a statement of drawing conditions applicable to such Letter of Credit, and if such Request for Issuance relates to an amendment or modification of a Letter of Credit, it shall be accompanied by the consent of the beneficiary of the Letter of Credit thereto. Each Request for Issuance shall be irrevocable unless modified or rescinded by the Borrower not less than one day prior to the proposed date of issuance (or effectiveness) specified therein. Not later than 12:00 noon on the proposed date of issuance (or effectiveness) specified in such Request for Issuance, and upon fulfillment of the applicable conditions precedent and the other requirements set forth herein, the LC Issuing Bank shall issue (or extend, amend or modify) such Letter of Credit and provide notice and a copy thereof to the Agent, which shall promptly furnish copies thereof to the Lenders.

No Letter of Credit shall be requested or issued hereunder if, after the issuance thereof, the Outstanding Credits would exceed the total Commitments.

The Borrower hereby agrees to pay to the Agent for the account of the LC Issuing Bank and, if they shall have purchased participations in the reimbursement obligations of the Borrower pursuant to subsection (d) below, the Lenders, on demand made by the LC Issuing Bank to the Borrower, on and after each date on which the LC Issuing Bank shall pay any amount under any Letter of Credit issued by the LC Issuing Bank, a sum equal to the amount so paid plus interest on such amount from the date so paid by the LC Issuing Bank until repayment to the LC Issuing Bank in full at a fluctuating interest rate per annum equal to the interest rate applicable to Base Rate Advances plus, if any amount paid by the LC Issuing Bank under a Letter of Credit is not reimbursed by the Borrower within three Business Days, 2%.

If the LC Issuing Bank shall not have been reimbursed in full for any payment made by the LC Issuing Bank under a Letter of Credit issued by the LC Issuing Bank on the date of such payment, the LC Issuing Bank shall give the Agent and each Lender prompt notice thereof (an “LC Payment Notice”) no later than 12:00 noon on the Business Day immediately succeeding the date of such payment by the LC Issuing Bank. Each Lender severally agrees to purchase a participation in the reimbursement obligation of the Borrower to the LC Issuing Bank by paying to the Agent for the account of the LC Issuing Bank an amount equal to such Lender’s Percentage of such unreimbursed amount paid by the LC Issuing Bank, plus interest on such amount at a rate per annum equal to the Federal Funds Rate from the date of the payment by the LC Issuing Bank to the date of payment to the LC Issuing Bank by such Lender. Each such payment by a Lender shall be made not later than 3:00 P.M. on the later to occur of (i) the Business Day immediately following the date of such payment by the LC Issuing Bank and (ii) the Business Day on which such Lender shall have received an LC Payment Notice from the LC Issuing Bank. Each Lender’s obligation to make each such payment to the Agent for the account of the LC Issuing Bank shall be several and shall not be affected by the occurrence or continuance of an Event of Default or the failure of any other Lender to make any payment under this Section 2.03(d). Each Lender further agrees that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

The failure of any Lender to make any payment to the Agent for the account of the LC Issuing Bank in accordance with subsection (d) above shall not relieve any other Lender of its obligation to make payment, but no Lender shall be responsible for the failure of any other Lender. If any Lender (a “Non-Performing Lender”) shall fail to make any payment to the Agent for the account of the LC Issuing Bank in accordance with subsection (d) above within five Business Days after the LC Payment Notice relating thereto, then, for so long as such failure shall continue, the LC Issuing Bank shall be deemed, for purposes of Section 8.01 and Article VI hereof, to be a Lender owed a Borrowing in an amount equal to the outstanding principal amount due and payable by such Non-Performing Lender to the Agent for the account of the LC Issuing Bank pursuant to subsection (d) above. Any Non-Performing Lender and the Borrower (without waiving any claim against such Lender for such Lender’s failure to purchase a participation in the reimbursement obligations of the Borrower under subsection (d) above) severally agree to pay to the Agent for the account of the LC Issuing Bank forthwith on demand such amount, together with interest thereon for each day from the date such Lender would have purchased its participation had it complied with the requirements of subsection (d) above until the date such amount is paid to the Agent at (i) in the case of the Borrower, the interest rate applicable at the time to Base Rate Advances and (ii) in the case of such Lender, the Federal Funds Rate.

The payment obligations of each Lender under Section 2.03(d) and of the Borrower under this Agreement in respect of any payment under any Letter of Credit by the LC Issuing Bank shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances:

any lack of validity or enforceability of this Agreement, any other Loan Document or any other agreement or instrument relating thereto or to such Letter of Credit;

any amendment or waiver of, or any consent to departure from, the terms of this Agreement, any other Loan Document or such Letter of Credit;

the existence of any claim, set-off, defense or other right which the Borrower may have at any time against any beneficiary, or any transferee, of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the LC Issuing Bank, or any other Person, whether in connection with this Agreement, the transactions contemplated hereby, thereby or by such Letter of Credit, or any unrelated transaction;

any statement or any other document presented under such Letter of Credit reasonably proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

 payment in good faith by the LC Issuing Bank under the Letter of Credit issued by the LC Issuing Bank against presentation of a draft or certificate that does not comply with the terms of such Letter of Credit; or

any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

The Borrower assumes all risks of the acts and omissions of any beneficiary or transferee of any Letter of Credit. Neither the LC Issuing Bank, the Lenders nor any of their respective officers, directors, employees, agents or Affiliates shall be liable or responsible for (i) the use that may be made of such Letter of Credit or any acts or omissions of any beneficiary or transferee thereof in connection therewith; (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (iii) payment by the LC Issuing Bank against presentation of documents that do not comply with the terms of such Letter of Credit, including failure of any documents to bear any reference or adequate reference to such Letter of Credit; or (iv) any other circumstances whatsoever in making or failing to make payment under such Letter of Credit. Notwithstanding any provision to the contrary contained in any Loan Document, the Borrower and each Lender shall have the right to bring suit against the LC Issuing Bank, and the LC Issuing Bank shall be liable to the Borrower and any Lender, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower or such Lender which the Borrower or such Lender proves were caused by the LC Issuing Bank’s willful misconduct or gross negligence, including, in the case of the Borrower, the LC Issuing Bank’s willful failure to make timely payment under such Letter of Credit following the presentation to it by the beneficiary thereof of a draft and accompanying certificate(s) that strictly comply with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, the LC Issuing Bank may accept sight drafts and accompanying certificates presented under the Letter of Credit issued by the LC Issuing Bank that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and payment against such documents shall not constitute willful misconduct or gross negligence by the LC Issuing Bank. Notwithstanding the foregoing, no Lender shall be obligated to indemnify the Borrower for damages caused by the LC Issuing Bank’s willful misconduct or gross negligence.

Fees.

The Borrower agrees to pay to the Agent for the account of each Lender the Facility Fee, from the date hereof, in the case of each Bank, and from the effective date specified in the Lender Assignment pursuant to which it became a Lender, in the case of each other Lender, until the later of the Termination Date and the date all Advances are paid in full, payable quarterly in arrears on the last day of each March, June, September and December during the term of such Lender’s Commitment, commencing December 31, 2003, and on the later of the Termination Date and the date all Advances are paid in full.

The Borrower shall pay to the Agent for the account of each Lender a fee (the “LC Fee”) on the average daily amount of the sum of the undrawn stated amounts of all Letters of Credit outstanding on each such day, from the date hereof until the later to occur of the Termination Date and the date on which no Letters of Credit are outstanding, payable on the last day of each March, June, September and December (commencing December 31, 2003) and such later date, at a rate equal at all times to the Applicable Margin in effect from time to time for Eurodollar Rate Advances. In addition, the Borrower shall pay to the LC Issuing Bank such fees for the issuance and maintenance of Letters of Credit and for drawings thereunder as may be separately agreed between the Borrower and the LC Issuing Bank.

In addition to the fees provided for in subsections (a) and (b) above, the Borrower shall pay (i) to the Agent and the LC Issuing Bank, for their own accounts, such fees as are provided for in the Administrative Agency Fee Letter and (ii) to the Lenders and the Co-Lead Arrangers, for their own accounts, such fees as are provided for in the Arranger Fee Letter.

Reduction of the Commitments.

The Borrower shall have the right, upon at least three Business Days’ notice to the Agent, to terminate in whole or reduce ratably in part the unused portions of the respective Commitments of the Lenders; provided that the aggregate amount of the Commitments of the Lenders shall not be reduced to an amount which is less than the aggregate principal amount of the Extensions of Credit then outstanding; and provided, further, that each partial reduction shall be in a minimum amount of $10,000,000 or any whole multiple of $1,000,000 in excess thereof.

On and after any date following the effective date of the Term Election, if the Available Commitments shall exceed the aggregate principal amount of Advances outstanding, the Available Commitments shall automatically be reduced on such date by an amount equal to such excess.

On the Termination Date, the Commitments of the Lenders shall be reduced to zero.

Any termination or reduction of the Commitments under this Section 2.05 shall be irrevocable, and the Commitments shall not thereafter be reinstated.

Repayment of Advances. The Borrower shall repay the principal amount of each Advance made by each Lender on the Termination Date.

Interest on Advances. The Borrower shall pay interest on the unpaid principal amount of each Advance owing to each Lender from the date of such Advance until such principal amount shall be paid in full, at the Applicable Rate for such Advance (except as otherwise provided in this Section 2.07), payable as follows:

Base Rate Advances. If such Advance is a Base Rate Advance, interest thereon shall be payable quarterly in arrears on the last day of each March, June, September and December, on the date of any Conversion of such Base Rate Advance and on the date such Base Rate Advance shall become due and payable or shall otherwise be paid in full; provided that at any time an Event of Default shall have occurred and be continuing, each Base Rate Advance shall bear interest payable on demand, at a rate per annum equal at all times to the Default Rate.

Eurodollar Rate Advances. If such Advance is a Eurodollar Rate Advance, interest thereon shall be payable on the last day of such Interest Period and, if the Interest Period for such Advance has a duration of more than three months, on that day of each third month during such Interest Period that corresponds to the first day of such Interest Period (or, if any such month does not have a corresponding day, then on the last day of such month); provided that at any time an Event of Default shall have occurred and be continuing, each Eurodollar Rate Advance shall bear interest payable on demand, at a rate per annum equal at all times to the Default Rate.

Additional Interest on Eurodollar Rate Advances. The Borrower shall pay to Agent for the account of each Lender any costs actually incurred by such Lender with respect to Eurodollar Rate Advances that are attributable to such Lender’s compliance with regulations of the Board of Governors of the Federal Reserve System requiring the maintenance of reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities. Such costs shall be paid to the Agent for the account of such Lender in the form of additional interest on the unpaid principal amount of each Eurodollar Rate Advance of such Lender, from the date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Advance. Such additional interest shall be determined by such Lender and notified to the Borrower through the Agent. A certificate as to the amount of such additional interest, submitted to the Borrower and the Agent by such Lender, shall be conclusive and binding for all purposes, absent manifest error, provided that the determination thereof shall have been made by such Lender in good faith.

Interest Rate Determination.

Each Reference Bank agrees to furnish to the Agent timely information for the purpose of determining each Eurodollar Rate. If any one or more of the Reference Banks shall not furnish such timely information to the Agent for the purpose of determining any such interest rate, the Agent shall determine such interest rate on the basis of timely information furnished by the remaining Reference Banks.

The Agent shall give prompt notice to the Borrower and the Lenders of the applicable interest rate determined by the Agent for purposes of Section 2.07(a) or (b), and the applicable rate, if any, furnished by each Reference Bank for the purpose of determining the applicable interest rate under Section 2.07(b).

If fewer than two Reference Banks furnish timely information to the Agent for determining the Eurodollar Rate, due to the unavailability of funds to such Reference Banks in the relevant financial markets:

the Agent shall forthwith notify the Borrower and the Lenders that the interest rate cannot be determined for Eurodollar Rate Advances;

each such Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance (or if such Advance is then a Base Rate Advance, will continue as a Base Rate Advance); and

the obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

If, with respect to any Eurodollar Rate Advances, the Majority Lenders notify the Agent that the Eurodollar Rate for any Interest Period for such Advances will not adequately reflect the cost to such Majority Lenders of making, funding or maintaining their respective Eurodollar Rate Advances for such Interest Period, the Agent shall forthwith so notify the Borrower and the Lenders, whereupon:

each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance; and

the obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

If the Borrower shall fail to (i) select the duration of any Interest Period for any Eurodollar Rate Advance in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01 or (ii) provide a Notice of Conversion with respect to any Eurodollar Rate Advance on or prior to 12:00 noon on the third Business Day prior to the last day of the Interest Period applicable thereto, the Agent will forthwith so notify the Borrower and the Lenders and such Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance.

On the date on which the aggregate unpaid principal amount of Advances comprising any Borrowing shall be reduced, by payment or prepayment or otherwise, to less than the product of (i) $1,000,000 and (ii) the number of Lenders on such date, such Advances shall, if they are Advances of a Type other than Base Rate Advances, automatically Convert into Base Rate Advances, and on and after such date the right of the Borrower to Convert such Advances into Advances of a Type other than Base Rate Advances shall terminate; provided, however, that if and so long as each such Advance shall be of the same Type and have the same Interest Period as Advances comprising another Borrowing or other Borrowings, and the aggregate unpaid principal amount of all such Advances shall equal or exceed the product of (i) $1,000,000 and (ii) the number of Lenders on such date, the Borrower shall have the right to continue all such Advances as, or to Convert all such Advances into, Advances of such Type having such Interest Period.

Upon the occurrence and during the continuance of any Event of Default, each outstanding Eurodollar Rate Advance shall automatically Convert into a Base Rate Advance at the end of the Interest Period then in effect for such Eurodollar Rate Advance.

Voluntary Conversion of Advances. Subject to the conditions set forth below, the Borrower may, on any Business Day, by delivering a notice of Conversion (a “Notice of Conversion”) to the Agent not later than 12:00 noon (i) on the third Business Day prior to the date of the proposed Conversion, in the case of a Conversion to or in respect of Eurodollar Rate Advances and (ii) on the date of the proposed Conversion, in the case of a Conversion to or in respect of Base Rate Advances, and subject to the provisions of Sections 2.09 and 2.14, Convert all Advances of one Type comprising the same Borrowing into Advances of another Type; provided, however, that, in the case of any Conversion of any Eurodollar Rate Advances into Base Rate Advances on a day other than the last day of an Interest Period for such Eurodollar Rate Advances, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.04(b). Each such Notice of Conversion shall be in substantially the form of Exhibit 2.10 and shall, within the restrictions specified above, specify (A) the date of such Conversion, (B) the Advances to be Converted, (C) if such Conversion is into Eurodollar Rate Advances, the duration of the Interest Period for each such Advance, and (D) the aggregate amount of Advances proposed to be Converted. Notwithstanding the foregoing, the Borrower may not Convert Base Rate Advances into Eurodollar Rate Advances and may not select a new Interest Period for Eurodollar Rate Advances at any time an Event of Default has occurred and is continuing.

Optional Prepayments of Advances. The Borrower may, upon at least three Business Days’ notice to the Agent stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given the Borrower shall, prepay for the ratable account of the Lenders the outstanding principal amounts of the Advances comprising part of the same Borrowing in whole or ratably in part, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided, however, that each partial prepayment shall be in an aggregate principal amount not less than $1,000,000 (or, if lower, the principal amount outstanding hereunder on the date of such prepayment) or an integral multiple of $1,000,000 in excess thereof. In the case of any such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.04(b). Except as provided in this Section 2.11, the Borrower shall have no right to prepay any principal amount of any Advances.

Increased Costs.

If, due to either (i) the introduction of or any change (other than any change by way of imposition or increase of reserve requirements, in the case of Eurodollar Rate Advances, included in the Eurodollar Rate Reserve Percentage) in or to the interpretation of any law or regulation or (ii) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the force of law), there shall be any increase in the cost to any Lender of agreeing to make or making, funding or maintaining Eurodollar Rate Advances, then the Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the Agent), pay to the Agent for the account of such Lender additional amounts sufficient to compensate such Lender for such increased cost. A certificate as to the amount of such increased cost, submitted to the Borrower and the Agent by such Lender, shall be conclusive and binding for all purposes, absent manifest error, provided that the determination thereof shall have been made by such Lender in good faith.

If any Lender determines that compliance with any law or regulation or any guideline or request from any central bank or other governmental authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender or any corporation controlling such Lender and that the amount of such capital is increased by or based upon the existence of such Lender’s commitment to lend hereunder and other commitments of this type, then, upon demand by such Lender (with a copy of such demand to the Agent), the Borrower shall immediately pay to the Agent for the account of such Lender, from time to time as specified by such Lender, additional amounts sufficient to compensate such Lender or such corporation in the light of such circumstances, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender’s Commitment. A certificate as to such amounts submitted to the Borrower and the Agent by such Lender, describing in reasonable detail the manner in which such amounts have been calculated, shall be conclusive and binding for all purposes, absent manifest error, provided that the determination and allocation thereof shall have been made by such Lender in good faith.

Notwithstanding any provision of subsections (a) or (b) above to the contrary, no Lender shall be entitled to demand compensation or be compensated thereunder to the extent that such compensation relates to any period of time more than 60 days prior to the date upon which such Lender first notified the Borrower of the occurrence of the event entitling such Lender to such compensation (unless, and to the extent, that any such compensation so demanded shall relate to the retroactive application of any event so notified to the Borrower).

Illegality. Notwithstanding any other provision of this Agreement to the contrary, if any Lender (the “Affected Lender”) shall notify the Agent and the Borrower that the introduction of or any change in or to the interpretation of any law or regulation makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for the Affected Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, all Eurodollar Rate Advances of the Affected Lender shall, on the fifth Business Day following such notice from the Affected Lender, automatically be Converted into a like number of Base Rate Advances, each in the amount of the corresponding Eurodollar Rate Advance of the Affected Lender being so Converted (each such Advance, as so Converted, being an “Affected Lender Advance”), and the obligation of the Affected Lender to make, maintain, or Convert Advances into Eurodollar Rate Advances shall thereupon be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, or the Affected Lender has been replaced pursuant to Section 8.07(g). For purposes of any prepayment under this Agreement, each Affected Lender Advance shall be deemed to continue to be part of the same Borrowing as the Eurodollar Rate Advances to which it corresponded at the time of the Conversion of such Affected Lender Advance pursuant to this Section 2.13.

Payments and Computations.

The Borrower shall make each payment hereunder not later than 1:00 p.m. on the day when due in Dollars to the Agent at its address referred to in Section 8.02 in same day funds. The Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest or fees ratably (other than amounts payable pursuant to Section 2.08, 2.16, 2.18(c) or 8.04(b)) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of a Lender Assignment and recording of the information contained therein in the Register pursuant to Section 8.07(d), from and after the effective date specified in such Lender Assignment, the Agent shall make all payments hereunder in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Lender Assignment shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

The Borrower hereby authorizes each Lender, if and to the extent payment owed to such Lender is not made when due hereunder held by such Lender, to charge from time to time against any or all of the Borrower’s accounts with such Lender any amount so due.

All computations of interest based on clause (i) of the definition of “Alternate Base Rate” and of the Facility Fees shall be made by the Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate and the LC Fee and the Federal Funds Rate shall be made by the Agent, and all computations of interest pursuant to Section 2.09 shall be made by a Lender, on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Agent (or, in the case of Section 2.09, by a Lender) of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error, provided that such determination shall have been made by the Agent or such Lender, as the case may be, in good faith.

Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided, however, that if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders hereunder that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower shall not have so made such payment in full to the Agent, each Lender shall repay to the Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Agent, at the Federal Funds Rate.

Noteless Agreement; Evidence of Indebtedness.

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

The Agent shall also maintain accounts in which it will record (i) the amount of each Advance made hereunder, the Type thereof and the Interest Period (if any) with respect thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder, and (iii) the amount of any sum received by the Agent hereunder from the Borrower and each Lender’s share thereof.

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

Any Lender may request that its Advances be evidenced by a Note. In such event, the Borrower shall prepare, execute and deliver to such Lender a Note payable to the order of such Lender. Thereafter, the Advances evidenced by such Note and interest thereon shall at all times (including after any assignment pursuant to Section 8.07) be represented by one or more Notes payable to the order of the payee named therein or any assignee pursuant to Section 8.07, except to the extent that any such Lender or assignee subsequently returns any such Note for cancellation and requests that such Advances once again be evidenced as described in subsections (a) and (b) above.

Taxes.

Any and all payments by the Borrower hereunder and under the other Loan Documents shall be made, in accordance with Section 2.14, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender, the LC Issuing Bank and the Agent, taxes imposed on its overall net income and franchise taxes imposed on it by any jurisdiction, unless such Lender, the LC Issuing Bank or the Agent (as the case may be) would not have had such taxes imposed on it by such jurisdiction but for such Lender’s, the LC Issuing Bank’s or the Agent’s (as the case may be) having entered into this Agreement, having consummated the transactions contemplated hereby or having received payments by the Borrower hereunder or under the other Loan Documents (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any other Loan Document to any Lender, the LC Issuing Bank or the Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.16) such Lender, the LC Issuing Bank 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, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

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

The Borrower will indemnify each Lender, the LC Issuing Bank and the Agent for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.16) paid by such Lender, the LC Issuing Bank or the Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. This indemnification shall be made within 30 days from the date such Lender, the LC Issuing Bank or the Agent (as the case may be) makes written demand therefor. Nothing herein shall preclude the right of the Borrower to contest any such Taxes or Other Taxes so paid, and the Lenders in question, the LC Issuing Bank or the Agent (as the case may be) will, following notice from, and at the expense of, the Borrower, reasonably cooperate with the Borrower to preserve the Borrower’s rights to contest such Taxes or Other Taxes.

Within 30 days after the date of any payment of Taxes, the Borrower will furnish to the Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing payment thereof.

The LC Issuing Bank and each Lender agrees that, on or prior to the date upon which it shall become a party hereto, and upon the reasonable request from time to time of the Borrower or the Agent, the LC Issuing Bank or such Lender will deliver to the Borrower and the Agent either (i) a statement that it is organized under the laws of a jurisdiction within the United States or (ii) duly completed copies of such form or forms as may from time to time be prescribed by the United States Internal Revenue Service indicating that the LC Issuing Bank or such Lender is entitled to receive payments without deduction or withholding of any United States federal income taxes, as permitted by the Internal Revenue Code of 1986, as amended from time to time. The LC Issuing Bank and each Lender that delivers to the Borrower and the Agent the form or forms referred to in the preceding sentence further undertakes to deliver to the Borrower and the Agent further copies of such form or forms, or successor applicable form or forms, as the case may be, as and when any previous form filed by it hereunder shall expire or shall become incomplete or inaccurate in any respect. The LC Issuing Bank and each Lender represents and warrants that each such form supplied by it to the Agent and the Borrower pursuant to this subsection (e), and not superseded by another form supplied by it, is or will be, as the case may be, complete and accurate.

Any Lender claiming any additional amounts payable pursuant to this Section 2.16 shall use its best efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in this Section 2.16 shall survive the payment in full of principal and interest hereunder.

Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances made by it (other than pursuant to Section 2.08, 2.12, 2.16, 2.18(c) or 8.04(b)) or on account of the Borrower’s reimbursement obligations in respect of LC Outstandings in excess of its ratable share of payments obtained by all the Lenders on account of the Advances or on account of such reimbursement obligations, such Lender shall forthwith purchase from the other Lenders such participations in the Advances made by them and such reimbursement obligations as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery, together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.17 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

Extension of Revolving Commitment Termination Date; Term Election.

At least 30 but not more than 60 days prior to the then applicable Revolving Commitment Termination Date, the Borrower may, by delivering a written request to the Agent (each such request being irrevocable), request that the Revolving Commitment Termination Date be extended for an additional period of 364 days, commencing on the then applicable Revolving Commitment Termination Date. Any such notice shall also indicate whether the Borrower elects, in the event that the Lenders determine not to extend the Revolving Commitment Termination Date as requested by the Borrower, to extend the then applicable Termination Date to one year following such Termination Date (any such election to so extend the Termination Date being the “Term Election”). Upon receipt of any such notice, the Agent shall promptly communicate such request to the Lenders.

No earlier than 30 days prior, and no later than 20 days prior, to the then applicable Revolving Commitment Termination Date, the Lenders shall indicate to the Agent whether the Borrower’s request to so extend the Revolving Commitment Termination Date is acceptable to the Lenders (and, if so, the conditions, if any, relating to such acceptance), it being understood that the determination by each Lender will be in its sole and absolute discretion and that the failure of any Lender to so respond within such period shall be deemed to constitute a refusal by such Lender to consent to such request, with the result being that such request is denied (any Lender refusing or deemed to refuse any such request, a “Non-Consenting Lender”). The Agent shall notify the Borrower, in writing, of the Lenders’ decisions no later than 15 days prior to the then applicable Revolving Commitment Termination Date.

Subject to the satisfaction of the conditions set forth in Section 3.03, in the event that the sum of the Commitments of the Lenders that have consented to the Borrower’s request to extend the then applicable Revolving Commitment Termination Date (the “Consenting Lenders”) plus the Commitments of Non-Consenting Lenders with respect to such request that have been assigned pursuant to Section 8.07(g) hereof shall constitute greater than 50% of the aggregate Commitments, the then applicable Revolving Commitment Termination Date shall be extended for an additional period of 364 days with respect to the Commitments of such Consenting Lenders. The Commitments of Non-Consenting Lenders with respect to such request shall automatically terminate on the last day of the then applicable Revolving Commitment Termination Date (and the principal amount of all Advances made by such Non-Consenting Lenders, together with accrued interest and fees to such date, shall be repaid), unless assigned pursuant to Section 8.07(g) hereof; provided that, before the Borrower may solicit Eligible Assignees other than the Consenting Lenders, the Consenting Lenders shall have at least five days before the end of the then applicable Revolving Commitment Termination Date to determine whether to purchase by assignment the Commitments of such Non-Consenting Lenders.

In the event that any request by the Borrower pursuant to subsection (a) above shall be denied and the Borrower shall have indicated in such request that, in the event of such denial, it has determined to effect the Term Election, then, effective as of the Revolving Commitment Termination Date, the Termination Date shall be extended to the first anniversary of the Revolving Commitment Termination Date; provided that on such date and on the Revolving Commitment Termination Date (i) the representations and warranties contained in Section 4.01 are true and correct, before and after giving effect to the Term Election, and (ii) no event has occurred and is continuing, or would result from the Term Election, that constitutes an Event of Default or an Unmatured Default. In addition, in the event that the Borrower shall not have requested an extension of the Revolving Commitment Termination Date pursuant to subsection (a) above, the Borrower may nonetheless make the Term Election by giving written notice to such effect to the Agent (which shall promptly give notice thereof to the Lenders) at least ten Business Days prior to the Revolving Commitment Termination Date, whereupon, effective as of the Revolving Commitment Termination Date, the Termination Date shall be extended to the first anniversary of the Revolving Commitment Termination Date; provided that on such date and on the then applicable Revolving Commitment Termination Date (i) the representations and warranties contained in Section 4.01 are true and correct, before and after giving effect to the Term Election, and (ii) no event has occurred and is continuing, or would result from the Term Election, that constitutes an Event of Default or an Unmatured Default.

Notwithstanding anything contained herein to the contrary, the Borrower’s right to effect the Term Election as provided in either subsection (a) or (d) above shall not affect any rights or remedies that the Lenders or the Agent may have at such time under Section 6.01 as a result of any Event of Default or Unmatured Default that may have occurred and then be continuing, either at the time of the giving of such notice or on the then applicable Revolving Commitment Termination Date.

Representations and Warranties of the Borrower. The Borrower represents and warrants as follows:

This Agreement is, and each other Loan Document to which the Borrower will be a party when executed and delivered hereunder will be, legal, valid and binding obligations of the Borrower enforceable against the Borrower in accordance with their respective terms, subject to the qualifications, however, that the enforcement of the rights and remedies herein and therein is subject to bankruptcy and other similar laws of general application affecting rights and remedies of creditors and that the remedy of specific performance or of injunctive relief is subject to the discretion of the court before which any proceedings therefor may be brought.

Since December 31, 2002, there has been no Material Adverse Change.

Except as disclosed in the Borrower’s Report on Form 10-K for the year ended December 31, 2002 and Report on Form 10-Q for the period ended June 30, 2003, there is no pending or threatened action or proceeding affecting the Borrower or any of its Subsidiaries or properties before any court, governmental agency or arbitrator, that might reasonably be expected to constitute a Material Adverse Change and since December 31, 2002 there have been no material adverse developments in any action or proceeding so disclosed.

No ERISA Event has occurred or is reasonably expected to occur with respect to any Plan of the Borrower or any of its ERISA Affiliates which would result in a material liability to the Borrower. No “prohibited transaction” has occurred with respect to any Plan of the Borrower that is reasonably expected to result in a material liability to the Borrower.

The Borrower has filed all tax returns (Federal, state and local) required to be filed and paid all taxes shown thereon to be due, including interest and penalties, or, to the extent the Borrower is contesting in good faith an assertion of liability based on such returns, has provided adequate reserves for payment thereof in accordance with GAAP.

Neither the Borrower nor any Subsidiary of the Borrower is engaged principally, or as one of its important activities, in the business of purchasing or carrying Margin Stock, or extending credit for the purpose of purchasing or carrying Margin Stock. After the making of each Extension of Credit, Margin Stock will constitute less than 25 percent of the assets (as determined by any reasonable method) of the Borrower and its Subsidiaries on a consolidated basis.

Affirmative Covenants. So long as any amount in respect of this Agreement shall remain unpaid, any Lender shall have any Commitment or any Letter of Credit shall remain outstanding, the Borrower will, unless the Majority Lenders shall otherwise consent in writing:

Payment of Taxes, Etc. Pay and discharge, and cause each of its Subsidiaries to pay and discharge, before the same shall become delinquent, all taxes, assessments and governmental charges, royalties or levies imposed upon it or upon its property except, in the case of taxes, to the extent the Borrower or such Subsidiary is contesting the same in good faith and by appropriate proceedings and has set aside adequate reserves for the payment thereof in accordance with GAAP.

Preservation of Existence, Etc. Preserve and maintain, and cause each of its Subsidiaries to preserve and maintain, its corporate existence, material rights (statutory and otherwise) and franchises; provided, however, that neither the Borrower nor any of its Subsidiaries shall be required to preserve and maintain any such right or franchise, and no such Subsidiary shall be required to preserve and maintain its corporate existence, unless the failure to do so would constitute a Material Adverse Change.

Compliance with Laws, Etc. Comply, and cause each of its Subsidiaries to comply, with the requirements of all applicable laws, rules, regulations and orders of any governmental authority, including without limitation any such laws, rules, regulations and orders relating to zoning, environmental protection, use and disposal of Hazardous Substances, land use, ERISA, construction and building restrictions, and employee safety and health matters relating to business operations, the non-compliance with which would constitute a Material Adverse Change.

The Borrower agrees that it shall have no right of set-off, deduction or counterclaim in respect of its obligations hereunder, and that the obligations of the Lenders hereunder are several and not joint.

Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Lender Assignment, (x) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Lender Assignment, have the rights and obligations of a Lender hereunder and (y) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Lender Assignment, relinquish its rights and be released from its obligations under this Agreement (and, in the case of a Lender Assignment covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto). Notwithstanding anything to the contrary contained in this Agreement, any Lender may at any time, with notice to the Borrower, the Agent and the LC Issuing Bank, assign all or any portion of the Advances owing to it to any other Lender or any Affiliate of a Lender. No such assignment, other than to an Eligible Assignee, a Lender or an Affiliate of a Lender, shall release the assigning Lender from its obligations hereunder.

By executing and delivering a Lender Assignment, the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Lender Assignment, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with any Loan Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document or any other instrument or document furnished pursuant thereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance or observance by the Borrower of any of its obligations under any Loan Document or any other instrument or document furnished pursuant thereto; (iii) such assignee confirms that it has received a copy of each Loan Document, together with copies of the financial statements referred to in Section 4.01(f) hereof and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Lender Assignment; (iv) such assignee will, independently and without reliance upon the Agent, such assigning Lender 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 the Loan Documents; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers under the Loan Documents as are delegated to the Agent by the terms thereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of the Loan Documents are required to be performed by it as a Lender.

The Agent shall maintain at its address referred to in Section 8.02 a copy of each Lender Assignment delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Advances owing to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

Upon its receipt of a Lender Assignment executed by an assigning Lender and an assignee representing that it is an Eligible Assignee, together with any Note or Notes (if any) subject to such assignment, the Agent shall, if such Lender Assignment has been completed and is in substantially the form of Exhibit 8.07 hereto, (i) accept such Lender Assignment, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower.

Each Lender may sell participations to one or more banks, financial institutions or other entities in all or a portion of its rights and obligations under the Loan Documents (including, without limitation, all or a portion of its Commitment, the Advances owing to it and the Note or Notes (if any) held by it); provided, however, that (i) such Lender’s obligations under this Agreement (including, without limitation, its Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder of any such Note (if any) for all purposes of this Agreement, and (iv) the Borrower, the Agent 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.

Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 8.07, disclose to the assignee or participant or proposed assignee or participant, any information relating to the Borrower furnished to such Lender by or on behalf of the Borrower; provided that, prior to any such disclosure, the assignee or participant or proposed assignee or participant shall agree, in accordance with the terms of Section 8.08, to preserve the confidentiality of any Confidential Information relating to the Borrower received by it from such Lender.

If any Lender (or any bank, financial institution, or other entity to which such Lender has sold a participation) shall (i) make any demand for payment under Section 2.08 or 2.12, (ii) give notice to the Agent pursuant to Section 2.13 or (iii) determine not to extend the Revolving Commitment Termination Date in response to any request by the Borrower pursuant to Section 2.18, then (A) in the case of any demand made under clause (i) above, or the occurrence of the event described in clause (ii) above, within 30 days after any such demand or occurrence (if, but only if, in the case of any demanded payment described in clause (i), such demanded payment has been made by the Borrower), and (B) in the case of the occurrence of the event described in clause (iii) above, at any time prior to the then-scheduled Revolving Commitment Termination Date, the Borrower may, with the approval of the Agent and the LC Issuing Bank (which approval shall not be unreasonably withheld), and provided that no Event of Default or Unmatured Default shall then have occurred and be continuing, demand that such Lender assign in accordance with this Section 8.07 to one or more Eligible Assignees designated by the Borrower all (but not less than all) of such Lender’s Commitment and the Advances owing to it within the period ending on the latest to occur of (x) the last day in the period described in clause (A) or (B) above, as applicable, and (y) the last day of the longest of the then-current Interest Periods for such Advances. If any such Eligible Assignee designated by the Borrower shall fail to consummate such assignment on terms acceptable to such Lender, or if the Borrower shall fail to designate any such Eligible Assignees for all or part of such Lender’s Commitment or Advances, then such demand by the Borrower shall become ineffective; it being understood for purposes of this subsection (g) that such assignment shall be conclusively deemed to be on terms acceptable to such Lender, and such Lender shall be compelled to consummate such assignment to an Eligible Assignee designated by the Borrower, if such Eligible Assignee (1) shall agree to such assignment by entering into a Lender Assignment with such Lender and (2) shall offer compensation to such Lender in an amount equal to all amounts then owing by the Borrower to such Lender hereunder, whether for principal, interest, fees, costs or expenses (other than the demanded payment referred to above and payable by the Borrower as a condition to the Borrower’s right to demand such assignment), or otherwise.

Anything in this Section 8.07 to the contrary notwithstanding, any Lender may assign and pledge all or any portion of its Commitment and the Advances owing to it to any Federal Reserve Bank (and its transferees) as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank. No such assignment shall release the assigning Lender from its obligations hereunder.

Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”) of such Granting Lender identified as such in writing from time to time by the Granting Lender to the Agent, the LC Issuing Bank and the Borrower, the option to provide to the Borrower all or any part of any Advance that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any such SPC to make any Advance, (ii) if such SPC elects not to exercise such option or otherwise fails to provide all or any part of such Advance, the Granting Lender shall be obligated to make such Advance pursuant to the terms hereof and (iii) no SPC or Granting Lender shall be entitled to receive any greater amount pursuant to Section 2.12 or 8.04(b) than the Granting Lender would have been entitled to receive had the Granting Lender not otherwise granted such SPC the option to provide any Advance to the Borrower. The making of an Advance by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Advance were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would otherwise be liable so long as, and to the extent that, the related Granting Lender provides such indemnity or makes such payment. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against or join any other person in instituting against such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. Notwithstanding the foregoing, the Granting Lender unconditionally agrees to indemnify the Borrower, the LC Issuing Bank, the Agent and each Lender against all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be incurred by or asserted against the Borrower, the LC Issuing Bank, the Agent or such Lender, as the case may be, in any way relating to or arising as a consequence of any such forbearance or delay in the initiation of any such proceeding against its SPC. Each party hereto hereby acknowledges and agrees that no SPC shall have the rights of a Lender hereunder, such rights being retained by the applicable Granting Lender. Accordingly, and without limiting the foregoing, each party hereby further acknowledges and agrees that no SPC shall have any voting rights hereunder and that the voting rights attributable to any Advance made by an SPC shall be exercised only by the relevant Granting Lender and that each Granting Lender shall serve as the administrative agent and attorney-in-fact for its SPC and shall on behalf of its SPC receive any and all payments made for the benefit of such SPC and take all actions hereunder to the extent, if any, such SPC shall have any rights hereunder. In addition, notwithstanding anything to the contrary contained in this Agreement any SPC may (i) with notice to, but without the prior written consent of any other party hereto, assign all or a portion of its interest in any Advances to the Granting Lender and (ii) disclose on a confidential basis any information relating to its Advances to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This Section 8.07(i) may not be amended without the prior written consent of each Granting Lender, all or any part of whose Advance is being funded by an SPC at the time of such amendment.
