the amount available to be drawn thereunder (as a result of lapse of time, the occurrence of certain events or otherwise), then the stated amount thereof shall be the maximum amount available to be drawn thereunder during the remaining term thereof assuming all such increases take effect, regardless of whether such maximum amount is then available; and (b) if a Facility LC has expired by its terms but any amount may still be drawn thereunder by reason of the operation of Rule 3.14 of International Standby Practices 1998, then the stated amount of such Facility LC shall be deemed to be the amount remaining available to be drawn thereunder.

SECTION 2.01 Commitments. Each Lender severally agrees, on the terms and conditions hereinafter set forth, to (a) make Revolving Loans to the Borrower, (b) participate in Swingline Loans of any Swingline Lender, and (c) participate in Facility LCs issued upon the request of the Borrower, in each case from time to time during the period from the date hereof to such Lender’s Termination Date, in an aggregate amount not to exceed such Lender’s Commitment Amount as in effect from time to time; provided that (i) the aggregate principal amount of all Revolving Loans by such Lender to the Borrower shall not exceed such Lender’s Pro Rata Share of the aggregate principal amount of all outstanding Revolving Loans; (ii) such Lender’s participation in Swingline Loans shall not exceed such Lender’s Pro Rata Share of all Swingline Obligations; (iii) such Lender’s participation in Facility LCs shall not exceed such Lender’s Pro Rata Share of all LC Obligations; and (iv) the Outstanding Credit Extensions shall not at any time exceed the Aggregate Commitment Amount. Within the foregoing limits and subject to the other provisions hereof, the Borrower may from time to time borrow, prepay pursuant to Section 2.10 and reborrow hereunder prior to the latest Termination Date.

(i) The Borrower may request Revolving Loans by giving notice (a “Notice of Borrowing”) to the Administrative Agent (which shall promptly advise each Lender of its receipt thereof) not later than 11:00 A.M., New York City time, on the third Business Day prior to the date of any proposed borrowing of Eurodollar Advances and on the date of any proposed borrowing of Base Rate Advances. Each Notice of Borrowing shall be sent by facsimile and shall be in substantially the form of Exhibit B, specifying therein (1) the requested date of borrowing (which shall be a Business Day), (2) the Type of Advances requested, (3) the aggregate principal amount of the requested Revolving Loan and (4) in the case of a borrowing of Eurodollar Advances, the initial Interest Period therefor. Each Lender shall, before 2:00 P.M., New York City time, on the date of such borrowing, make available for the account of its Applicable Lending Office to the Administrative Agent at its address referred to in Section 8.02, in same day funds, such Lender’s ratable portion of the requested borrowing. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent will make such funds available to the Borrower at the Administrative Agent’s aforesaid address.

(ii) Each Notice of Borrowing shall be irrevocable and binding on the Borrower. If a Notice of Borrowing requests Eurodollar 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 requested borrowing date the applicable conditions set forth in Article III, including 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 requested Advance to be made by such Lender.

(iii) Unless the Administrative Agent shall have received notice from a Lender prior to the date of any requested borrowing (or, in the case of a borrowing of Base Rate Advances to be made on the same Business Day as the Administrative Agent’s receipt of the relevant Notice of Borrowing, prior to 11:30 A.M., New York City time, on such Business Day) that such Lender will not make available to the Administrative Agent such Lender’s ratable portion of such borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the requested borrowing date in accordance with Section 2.02(a)(i) and the Administrative 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 ratable portion available to the Administrative Agent, such Lender and the Borrower severally agree to repay to the Administrative 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 Administrative Agent, at (1) in the case of the Borrower, the interest rate applicable at the time to Revolving Loans made in connection with such borrowing and (2) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement.

(iv) The failure of any Lender to make the Revolving Loan to be made by it on any borrowing date shall not relieve any other Lender of its obligation, if any, hereunder to make its Revolving Loan on such date, but no Lender shall be responsible for the failure of any other Lender to make any Revolving Advance to be made by such other Lender.

(v) Each Borrowing of Revolving Loans constituting Base Rate Advances shall at all times be in an aggregate amount of $5,000,000 or a higher integral multiple of $1,000,000; and each Borrowing of Eurodollar Advances shall at all times be in an aggregate amount of $10,000,000 or a higher integral multiple of $1,000,000. Notwithstanding anything to the contrary contained herein, the Borrower may not have more than 10 Borrowings of Eurodollar Advances outstanding at any time.

(i) Subject to the terms and conditions set forth herein, each Swingline Lender severally agrees to make Swingline Loans to the Borrower from time to time during the period from the date hereof to such Swingline Lender’s Termination Date, in an aggregate principal amount at any time outstanding that will not result in (1) the aggregate principal

amount of outstanding Swingline Loans exceeding $50,000,000 for each such Swingline Lender, and (2) the sum of the total Outstanding Credit Extensions exceeding the Aggregate Commitment Amount; provided that such Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Swingline Loans. All Swingline Loans shall be made as Base Rate Advances or, subject to the provisions of Section 2.06(c), Cost of Funds Advances, and shall be repaid no later than 7 days after the date any Swingline Lender makes a Swingline Loan available to the Borrower (“Swingline Repayment Date”).

(ii) To request a Swingline Loan, the Borrower shall notify the Administrative Agent of such request by telephone (confirmed by facsimile), not later than 12:00 noon, New York City time, on the day of a proposed Swingline Loan. Each such notice shall be irrevocable and shall specify the Swingline Lender from which the Borrower seeks the Swingline Loan, the Type of Advance, the requested date (which shall be a Business Day) and amount of the requested Swingline Loan. The Administrative Agent will promptly advise the applicable Swingline Lender of any such notice received from the Borrower. The applicable Swingline Lender shall make each Swingline Loan available to the Borrower by 3:00 P.M., New York City time, on the requested date of such Swingline Loan, and each Swingline Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably sold to each Lender, and each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from such Swingline Lender, a participation in such Swingline Loan and the related Swingline Obligation in proportion to its Pro Rata Share.

(iii) If the Borrower fails to repay fully the Swingline Loan by the Swingline Repayment Date, the Borrower shall be deemed to have requested that a Revolving Loan constituting Base Rate Advances be disbursed to reimburse the Swingline Lender in an amount equal to the unpaid Swingline Loan. In such event, the Swingline Lender shall promptly notify the Administrative Agent. Promptly upon receipt of such notice, the Administrative Agent will give notice thereof to each Lender, specifying in such notice such Lender’s Pro Rata Share of such Advance. Each Lender shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the manner as provided in Section 2.02(a)(i) with respect to Revolving Loans made by such Lender (and Section 2.02(a)(i) shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Swingline Lender the amounts so received by it from the Lenders.

(iv) If any Swingline Loan is not fully refinanced by the making of the Base Rate Advances as provided in Section 2.02(b)(iii) above because the Borrower cannot satisfy the conditions set forth in Article III or for any other reason, the Swingline Lender may by written notice given to the Administrative Agent not later than 11:00 A.M., New York City time, on any Business Day require the Lenders to fund their participations on such Business Day in all of the Swingline Loans outstanding. Promptly upon receipt of such notice, the Administrative Agent will give notice thereof to each Lender, specifying in such notice such Lender’s Pro Rata Share of such Swingline Loans. Each Lender hereby

absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to the Administrative Agent, for the account of the Swingline Lender, such Lender’s Pro Rata Share of such Swingline Loans. Each Lender 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 Event of Default or 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 2.02(a)(i) with respect to Revolving Loans made by such Lender (and Section 2.02(a)(i) shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Swingline Lender the amounts so received by it from the Lenders. The Administrative Agent shall notify the 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 Administrative Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from the Borrower (or other party on behalf of the Borrower) in respect of a Swingline Loan after receipt by such Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Administrative Agent; any such amounts received by the Administrative Agent shall be promptly remitted by the Administrative Agent to the Lenders that shall have made their payments pursuant to this paragraph and to such Swingline Lender, as their interests may appear; provided that any such payment so remitted shall be repaid to such Swingline Lender or to the Administrative Agent, as applicable, if and to the extent such payment is required to be refunded to the Borrower for any reason. The purchase of participations in the Swingline Loan pursuant to this paragraph shall not relieve the Borrower of any default in the payment thereof.

(a) The Borrower agrees to pay to the Administrative Agent, for the account of each Lender, a facility fee at a rate per annum equal to the Facility Fee Rate on such Lender’s Pro Rata Share of the Aggregate Commitment Amount (or, after such Lender’s Termination Date, of the principal amount of all Outstanding Credit Extensions) for the period from the Effective Date to such Lender’s Termination Date (or, if later, the date on which all obligations of the Borrower to such Lender hereunder have been paid in full and such Lender has no participation interests in any LC Obligations), payable on the last day of each March, June, September and December and on the such Lenders’ Termination Date (and, if applicable, thereafter on demand).

(b) Utilization Fee. The Borrower agrees to pay to the Administrative Agent, for the account of each Lender, for each day on which the Outstanding Credit Extensions exceed 50% of the Aggregate Commitment Amount, a utilization fee at a rate per annum equal to the Utilization Fee Rate on such Lender’s Pro Rata Share of Outstanding Credit Extensions on such day, payable on the last day of each March, June, September and December and on such Lender’s Termination Date (and, if applicable, thereafter on demand).

(a) The Borrower shall have the right, upon at least two Business Days’ notice to the Administrative Agent, to ratably reduce the respective Commitment Amounts of the Lenders in accordance with their Pro Rata Shares; provided that the Aggregate Commitment Amount may not be reduced to an amount that is less than the Outstanding Credit Extensions; and provided, further, that each partial reduction of the Commitment Amounts shall be in the aggregate amount of $10,000,000 or a higher integral multiple of $1,000,000. Any reduction of the Commitment Amounts pursuant to this Section 2.04 shall be permanent, except as expressly provided otherwise herein.

(b) The Borrower may at any time, upon at least two Business Days’ notice to the Administrative Agent, terminate the Commitments so long as the Borrower concurrently pays all of its outstanding obligations hereunder.

SECTION 2.05 Repayment of Advances. The Borrower shall repay all outstanding Advances made by each Lender, and all other obligations of the Borrower to such Lender hereunder, on such Lender’s Termination Date.

SECTION 2.06 Interest on Advances. The Borrower shall pay interest on the unpaid principal amount of each Advance from the date of such Advance until such principal amount shall be paid in full, as follows:

(a) At all times such Advance is a Base Rate Advance, a rate per annum equal to the Base Rate in effect from time to time plus the Applicable Margin in effect from time to time, payable quarterly on the last day of each March, June, September and December, on the date such Base Rate Advance is converted to a Eurodollar Advance or paid in full and on such Lender’s Termination Date (and, if applicable, thereafter on demand).

(b) Subject to Section 2.07, at all times such Advance is a Eurodollar Advance, a rate per annum equal to the sum of the Eurodollar Rate for each applicable Interest Period plus the Applicable Margin in effect from time to time, payable on the last day of each Interest Period for such Eurodollar Advance (and, if any Interest Period for such Advance is six months, on the day that is three months after the first day of such Interest Period) or, if earlier, on the date such Eurodollar Advance is converted to a Base Rate Advance or paid in full and on such Lender’s Termination Date (and, if applicable, thereafter on demand).

(c) Swingline Loans may be a Cost of Funds Advance if the Borrower and the applicable Swingline Lender have expressly agreed to such Cost of Funds Advance (such agreement to be obtained by telephone, confirmed promptly to the Administrative Agent in writing) pursuant to the following procedures. If the Borrower desires a Cost of Funds Advance, (i) as part of the request in Section 2.02(b)(ii), the Borrower shall request a quote for a Cost of Funds Advance, and the applicable Swingline Lender shall within a reasonable time after receipt of the request directly contact the Borrower (which may be done by telephone) with its Cost of Funds Rate (confirmed by facsimile), (ii) the Borrower shall immediately inform such Swingline Lender of its decision as to whether to request a Cost of Funds Advance at the Cost of Funds Rate (which may be done by telephone and promptly confirmed in writing and which decision

shall be irrevocable), and (iii) if the Borrower has so informed such Swingline Lender that it does desire a Cost of Funds Advance at the Cost of Funds Rate, the Swingline Lender shall promptly make such Cost of Funds Advance available to the Borrower. At all times such Advance is a Cost of Funds Advance, the Borrower shall pay interest on the unpaid principal amount of such Cost of Funds Advance from the date of such Cost of Funds Advance until such principal amount shall be paid in full at a rate per annum equal to the Cost of Funds Rate in effect from time to time plus the Applicable Margin for Eurodollar Advances in effect from time to time.

SECTION 2.07 Additional Interest on Eurodollar Advances. The Borrower shall pay to each Lender, so long as such Lender shall be required under regulations of the Board of Governors of the Federal Reserve System to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Eurodollar Advance of such Lender, from the date of such Advance until such principal amount is paid in full or converted to a Base Rate Advance, at an interest rate per annum equal to the remainder obtained by subtracting (i) the Eurodollar Rate for each Interest Period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Advance; provided that no Lender shall be entitled to demand such additional interest more than 90 days following the last day of the Interest Period in respect of which such demand is made; provided, further, that the foregoing proviso shall in no way limit the right of any Lender to demand or receive such additional interest to the extent that such additional interest relates to the retroactive application of the reserve requirements described above if such demand is made within 90 days after the implementation of such retroactive reserve requirements. Such additional interest shall be determined by the applicable Lender and notified to the Borrower through the Administrative Agent, and such determination shall be conclusive and binding for all purposes, absent manifest error.

(a) The Administrative Agent shall give prompt notice to the Borrower and the Lenders of each applicable interest rate determined by the Administrative Agent for purposes of Section 2.06(a) or (b).

(b) If, with respect to any Borrowing of Eurodollar Advances, the Majority Lenders notify the Administrative 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 Advances for such Interest Period, the Administrative Agent shall forthwith so notify the Borrower and the Lenders, whereupon

(i) each Eurodollar Advance will automatically, on the last day of the then existing Interest Period therefor (unless prepaid or converted to a Base Rate Advance prior to such day), convert into a Base Rate Advance, and

(ii) the obligation of the Lenders to make, continue or convert into Eurodollar Advances shall be suspended until the Administrative Agent shall

notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

(a) The Borrower may on any Business Day, upon notice given to the Administrative Agent not later than 11:00 A.M., New York City time, on the third Business Day prior to the date of any proposed continuation of or conversion into Eurodollar Advances, and on the date of any proposed conversion into Base Rate Advances, and subject to the provisions of Sections 2.08 and 2.12, continue Eurodollar Advances for a new Interest Period or convert a Borrowing of Advances of one Type into Advances of the other Type; provided that any continuation of Eurodollar Advances or conversion of Eurodollar Advances into Base Rate Advances shall be made on, and only on, the last day of an Interest Period for such Eurodollar Advances, unless, in the case of such a conversion, the Borrower shall also reimburse the Lenders pursuant to Section 8.04(b) on the date of such conversion. Each such notice of a continuation or conversion shall, within the restrictions specified above, specify (i) the date of such continuation or conversion, (ii) the Advances to be continued or converted, and (iii) in the case of continuation of or conversion into Eurodollar Advances, the duration of the Interest Period for such Advances.

(b) If the Borrower fails to select the Type of any Advance or the duration of any Interest Period for any Borrowing of Eurodollar Advances in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01 and Section 2.09(a), the Administrative Agent will forthwith so notify the Borrower and the Lenders and such Advances will automatically, on the last day of the then existing Interest Period therefor, convert into Base Rate Advances.

SECTION 2.10 Prepayments. The Borrower may, upon notice to the Administrative Agent not later than 11:00 A.M., New York City time, at least three Business Days prior to any prepayment of Eurodollar Advances or on the date of any prepayment of Base Rate Advances, in each case stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given the Borrower shall, prepay the outstanding principal amounts of the Advances made as 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 that (i) each partial prepayment shall be in an aggregate principal amount not less than $10,000,000 or a higher integral multiple of $1,000,000 in the case of any prepayment of Eurodollar Advances and $5,000,000 or a higher integral multiple of $1,000,000 in the case of any prepayment of Base Rate Advances (provided that if the aggregate amount of Advances made pursuant to Section 2.16 as a result of a drawing under a Facility LC is not $5,000,000 or a higher integral multiple of $1,000,000, then the next prepayment of Base Rate Advances shall be in an aggregate amount that causes the aggregate principal amount of all Base Rate Advances to be either (x) zero or (y) $5,000,000 or a higher integral multiple of $1,000,000) and (ii) in the case of any such prepayment of a Eurodollar Advance, the Borrower shall be obligated to reimburse the Lenders pursuant to Section 8.04(b) on the date of such prepayment.

(a) If on or after the date of this Agreement, any Lender or LC Issuer determines that (i) the introduction of or any change (other than, in the case of Eurodollar Advances, any change by way of imposition or increase of reserve requirements, included in the Eurodollar Rate Reserve Percentage) in or in 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) shall increase the cost to such Lender or such LC Issuer, as the case may be, of agreeing to make or making, funding or maintaining Eurodollar Advances or of issuing or participating in any Facility LC, then the Borrower shall from time to time, upon demand by such Lender or such LC Issuer (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender or such LC Issuer additional amounts (without duplication of any amount payable pursuant to Section 2.14) sufficient to compensate such Lender or such LC Issuer for such increased cost; provided that no Lender shall be entitled to demand such compensation more than 90 days following the last day of the Interest Period in respect of which such demand is made and no LC Issuer shall be entitled to demand such compensation more than 90 days following the expiration or termination (by a drawing or otherwise) of the Facility LC in respect of which such demand is made; provided, further, that the foregoing proviso shall in no way limit the right of any Lender or an LC Issuer to demand or receive such compensation to the extent that such compensation relates to the retroactive application of any law, regulation, guideline or request described in clause (i) or (ii) above if such demand is made within 90 days after the implementation of such retroactive law, interpretation, guideline or request. A certificate as to the amount of such increased cost, submitted to the Borrower and the Administrative Agent by a Lender or an LC Issuer, shall be conclusive and binding for all purposes, absent manifest error.

(b) If any Lender or LC Issuer determines that, after the date of this Agreement, 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) regarding capital adequacy requirements affects or would affect the amount of capital required or expected to be maintained by such Lender or such LC Issuer or any Person controlling such Lender or such LC Issuer and that the amount of such capital is increased by or based upon the existence of such Lender’s Commitment, such LC Issuer’s commitment to issue Facility LCs, the Advances made by such Lender or the Reimbursement Obligations owed to such LC Issuer, as the case may be, then, upon demand by such Lender or such LC Issuer (with a copy of such demand to the Administrative Agent), the Borrower shall immediately pay to the Administrative Agent for the account of such Lender or such LC Issuer, from time to time as specified by such Lender or such LC Issuer, additional amounts sufficient to compensate such Lender, such LC Issuer or such controlling Person, as applicable, in the light of such circumstances, to the extent that such Lender determines such increase in capital to be allocable to the existence of such Lender’s Commitment or the Advances made by such Lender or such LC Issuer determines such increase in capital to be allocable to such LC Issuer’s commitment to issue Facility LCs or the Reimbursement Obligations owed to such LC Issuer; provided that no Lender shall be entitled to demand such compensation more than one year following the payment to or for the account of such Lender of all other amounts payable hereunder by the Borrower and the termination of such Lender’s Commitment and no LC Issuer shall be entitled to demand such compensation more than one year after the expiration or termination (by drawing or otherwise) of all Facility LCs issued by such LC Issuer and the termination of such LC Issuer’s commitment to issue Facility LCs; provided, further, that the foregoing proviso shall in no way limit the right of any Lender or

LC Issuer to demand or receive such compensation to the extent that such compensation relates to the retroactive application of any law, regulation, guideline or request described above if such demand is made within one year after the implementation of such retroactive law, interpretation, guideline or request. A certificate as to such amounts submitted to the Borrower and the Administrative Agent by the applicable Lender or LC Issuer shall be conclusive and binding, for all purposes, absent manifest error.

(c) Any Lender claiming compensation pursuant to this Section 2.11 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 compensation that may thereafter accrue and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

SECTION 2.12 Illegality. Notwithstanding any other provision of this Agreement, if any Lender shall notify the Administrative Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for such Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Advances or to fund or maintain Eurodollar Advances hereunder, (i) the obligation of such Lender to make, continue or convert Advances into Eurodollar Advances shall be suspended (subject to the following paragraph of this Section 2.12) until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist and (ii) all Eurodollar Advances of such Lender then outstanding shall, on the last day of the then applicable Interest Period (or such earlier date as such Lender shall designate upon not less than five Business Days’ prior written notice to the Administrative Agent), be automatically converted into Base Rate Advances.

If the obligation of any Lender to make, continue or convert into Eurodollar Advances has been suspended pursuant to the preceding paragraph, then, unless and until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, (i) all Advances that would otherwise be made by such Lender as Eurodollar Advances shall instead be made as Base Rate Advances and (ii) to the extent that Eurodollar Advances of such Lender have been converted into Base Rate Advances pursuant to the preceding paragraph or made instead as Base Rate Advances pursuant to the preceding clause (i), all payments and prepayments of principal that would have otherwise been applied to such Eurodollar Advances of such Lender shall be applied instead to such Base Rate Advances of such Lender.

(a) The Borrower shall make each payment hereunder not later than 12:00 noon, New York City time, on the day when due in U.S. dollars to the Administrative Agent at its address referred to in Section 8.02 in same day funds without setoff, counterclaim or other deduction. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal, interest, facility fees, utilization fees and letter of credit fees ratably (other than amounts payable pursuant to Section 2.02(a)(ii), 2.07, 2.11, 2.14 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 an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to Section 8.07(d), from the effective date specified in such Assignment and Acceptance, the Administrative Agent shall make all payments hereunder in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b) The Borrower hereby authorizes each Lender, if and to the extent any payment owed to such Lender by the Borrower is not made when due hereunder, to charge from time to time against any of the Borrower’s accounts with such Lender any amount so due. Each Lender agrees to notify the Borrower promptly after any such set-off and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such set-off and application.

(c) All computations of interest based on the Prime Rate shall be made by the Administrative 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 Cost of Funds Rate, Eurodollar Rate or the Federal Funds Rate and of fees shall be made by the Administrative Agent, and all computations of interest pursuant to Section 2.07 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 Administrative Agent (or, in the case of Section 2.07, by a Lender) of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(d) 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 any interest or fees, as the case may be; provided that if such extension would cause payment of interest on or principal of a Eurodollar Advance to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(e) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due by the Borrower to the Lenders hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative 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 Administrative Agent, each Lender shall repay to the Administrative 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 Administrative Agent, at the Federal Funds Rate.

(f) Notwithstanding anything to the contrary contained herein, any amount payable by the Borrower hereunder that is not paid when due (whether at stated maturity, by acceleration or otherwise) shall (to the fullest extent permitted by law) bear interest from the date

when due until paid in full at a rate per annum equal at all times to the Base Rate plus 2%, payable upon demand.

(a) All payments by or on behalf of the Borrower hereunder shall be made, in accordance with Section 2.13, 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, each LC Issuer and the Administrative Agent, taxes imposed on its net income, and franchise taxes imposed on it, by the jurisdiction under the laws of which such Lender, such LC Issuer or the Administrative Agent (as the case may be) is organized or any political subdivision thereof and, in the case of each Lender, taxes imposed on its net income, and franchise taxes imposed on it, by the jurisdiction of such Lender’s Applicable Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities, “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to any Lender, any LC Issuer or the Administrative 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 2.14) such Lender, such LC Issuer or the Administrative 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.

(b) In addition, the Borrower severally agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies to the extent arising from the execution, delivery or registration of this Agreement (all of the foregoing, “Other Taxes”).

(c) No Lender may claim or demand payment or reimbursement in respect of any Taxes or Other Taxes pursuant to this Section 2.14 if such Taxes or Other Taxes, as the case may be, were imposed solely as the result of a voluntary change in the location of the jurisdiction of such Lender’s Applicable Lending Office.

(d) The Borrower will indemnify each Lender, each LC Issuer and the Administrative Agent for the full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.14) paid by such Lender, such LC Issuer or the Administrative 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, such LC Issuer or the Administrative Agent (as the case may be) makes written demand therefor.

(e) Prior to the date of an initial borrowing hereunder in the case of each Lender listed on the signature pages hereof, and on the date of the Assignment and Acceptance pursuant to which it became a Lender in the case of each other Lender, and from time to time thereafter within 30 days from the date of request if requested by the Borrower or the Administrative

Agent, each Lender organized under the laws of a jurisdiction outside the United States shall provide the Administrative Agent and the Borrower with the forms prescribed by the Internal Revenue Service of the United States certifying that such Lender is exempt from United States withholding taxes with respect to all payments to be made to such Lender hereunder. If for any reason during the term of this Agreement, any Lender becomes unable to submit the forms referred to above or the information or representations contained therein are no longer accurate in any material respect, such Lender shall notify the Administrative Agent and the Borrower in writing to that effect. Unless the Borrower and the Administrative Agent have received forms or other documents satisfactory to them (as set forth above) indicating that payments hereunder are not subject to United States withholding tax, the Borrower or the Administrative Agent shall withhold taxes from such payments at the applicable statutory rate in the case of payments to or for any Lender organized under the laws of a jurisdiction outside the United States and such Lender may not claim or demand payment or reimbursement for such withheld taxes pursuant to this Section 2.14.

(f) Any Lender claiming any additional amounts payable pursuant to this Section 2.14 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 which may thereafter accrue and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

(g) If the Borrower makes any additional payment to any Lender pursuant to this Section 2.14 in respect of any Taxes or Other Taxes, and such Lender determines that it has received (i) a refund of such Taxes or Other Taxes or (ii) a credit against or relief or remission for, or a reduction in the amount of, any tax or other governmental charge attributable solely to any deduction or credit for any Taxes or Other Taxes with respect to which it has received payments under this Section 2.14, such Lender shall, to the extent that it can do so without prejudice to the retention of such refund, credit, relief, remission or reduction, pay to the Borrower such amount as such Lender shall have determined to be attributable to the deduction or withholding of such Taxes or Other Taxes. If such Lender determines that it was not entitled to such refund, credit, relief, remission or reduction to the full extent of any payment made pursuant to the first sentence of this Section 2.14(g), the Borrower shall upon notice and demand of such Lender promptly repay the amount of such overpayment. Any determination made by a Lender pursuant to this Section 2.14(g) shall in the absence of bad faith or manifest error be conclusive, and nothing in this Section 2.14(g) shall be construed as requiring any Lender to conduct its business or to arrange or alter in any respect its tax or financial affairs (except as required by Section 2.14(f)) so that it is entitled to receive such a refund, credit or reduction or as allowing any Person to inspect any records, including tax returns, of such Lender.

(h) Without prejudice to the survival of any other agreement of the Borrower or any Lender hereunder, the agreements and obligations of the Borrower and the Lenders contained in this Section 2.14 shall survive the payment in full of principal and interest hereunder and the termination of this Agreement; provided that no Lender shall be entitled to demand any payment from the Borrower under this Section 2.14 more than one year following the payment to or for the account of such Lender of all other amounts payable by the Borrower hereunder to such Lender and the termination of such Lender’s Commitment; provided, further,

that the foregoing proviso shall in no way limit the right of any Lender to demand or receive any payment under this Section 2.14 to the extent that such payment relates to the retroactive application of any Taxes or Other Taxes if such demand is made within one year after the implementation of such Taxes or Other Taxes.

SECTION 2.15 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 to the Borrower or its participation interest in any Facility LC issued for the account of the Borrower (other than pursuant to Section 2.02(a)(ii), 2.07, 2.11, 2.14, 2.17.7 or 8.04(b)) in excess of its ratable share of payments on account of the Advances to the Borrower and LC Obligations obtained by all Lenders, such Lender shall forthwith purchase from the other Lenders such participations in the Advances and/or LC Obligations as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them, provided 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 2.15 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.

SECTION 2.16.1 Issuance. Each LC Issuer agrees, on the terms and conditions set forth in this Agreement (including the limitations set forth in Section 2.01), upon the request of the Borrower, to issue standby letters of credit and to extend, increase or otherwise modify Facility LCs (“Modify,” and each such action a “Modification”) for the Borrower, from time to time from the date of this Agreement to the Termination Date; provided that (a) the aggregate amount of LC Obligations owed by the Borrower to any LC Issuer shall not exceed the amount agreed upon in writing between the Borrower and such LC Issuer; (b) the stated amount of all Facility LCs that have scheduled expiry dates after the next scheduled Termination Date for any Lender plus the aggregate principal amount of all Eurodollar Advances that have Interest Periods ending after such Termination Date shall not exceed the remainder of (i) the Aggregate Commitment Amount minus (ii) the aggregate amount of the Commitments that are scheduled to terminate on such Termination Date; and (c) no LC Issuer shall be obligated to issue or Modify any Facility LC if (i) any order, judgment or decree of any court or other governmental authority shall by its terms purport to enjoin or restrain such LC Issuer from issuing such Facility LC or (ii) any applicable law, or any request or directive from any governmental authority having jurisdiction over such LC Issuer, shall prohibit, or request or direct that such LC Issuer refrain from, the issuance of letters of credit generally or of such Facility LC in particular. Facility LCs may be issued for any proper corporate purpose. No Facility LC shall have an expiry date later than seven days prior

to the last scheduled Termination Date. By their execution of this Agreement, the parties hereto agree that on the Effective Date (without any further action by any Person), each Existing Letter of Credit shall be deemed to have been issued under this Agreement and the rights and obligations of the issuer and the account party thereunder shall be subject to the terms hereof.

SECTION 2.16.2 Participations. Upon the issuance or Modification by an LC Issuer of a Facility LC in accordance with this Section 2.16 (or, in this case of the Existing Letters of Credit, on the Effective Date), the applicable LC Issuer shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably sold to each Lender, and each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from such LC Issuer, a participation in such Facility LC (and each Modification thereof) and the related LC Obligations in proportion to its Pro Rata Share.

SECTION 2.16.3 Notice. Subject to Section 2.16.1, the Borrower shall give the applicable LC Issuer notice prior to 11:00 A.M., New York City time, at least five Business Days (or such lesser time as the applicable LC Issuer may agree) prior to the proposed date of issuance or Modification of each Facility LC, specifying the beneficiary, the proposed date of issuance (or Modification) and the expiry date of such Facility LC, and describing the proposed terms of such Facility LC and the nature of the transactions proposed to be supported thereby. Upon receipt of such notice, the applicable LC Issuer shall promptly notify the Administrative Agent, and the Administrative Agent shall promptly notify each Lender, of the contents thereof and of the amount of such Lender’s participation in such proposed Facility LC. The issuance or Modification by an LC Issuer of any Facility LC shall, in addition to the applicable conditions precedent set forth in Article III (the satisfaction of which an LC Issuer shall have no duty to ascertain; provided that no LC Issuer shall issue a Facility LC if such LC Issuer shall have received written notice (which has not been rescinded) from the Administrative Agent or any Lender that any applicable condition precedent to the issuance or modification of such Facility LC has not been satisfied and, in fact, such condition precedent is not satisfied at the requested time of issuance), be subject to the conditions precedent that such Facility LC shall be satisfactory to the applicable LC Issuer and that the Borrower shall have executed and delivered such application agreement and/or such other instruments and agreements relating to such Facility LC as such LC Issuer shall have reasonably requested (each a “Facility LC Application”). In the event of any conflict (including any additional terms requiring the posting of collateral) between the terms of this Agreement and the terms of any Facility LC Application, the terms of this Agreement shall control.

SECTION 2.16.4 LC Fees. The Borrower agrees to pay to the Administrative Agent, for the account of each Lender, a letter of credit fee at a rate per annum equal to the LC Fee Rate on such Lender’s Pro Rata Share of the undrawn stated amount of all Facility LCs for the period from the Effective Date to such Lender’s Termination Date (or, if later, the date on which such Lender has no participation interests in the Facility LCs), payable in arrears on the last day of each March, June, September and December and on the applicable Termination Date (and, if applicable, thereafter on demand). The Borrower also agrees to pay to the applicable LC Issuer for its own account (x) fronting

fees in amounts and at times agreed upon between such LC Issuer and the Borrower and (y) documentary and processing charges in connection with the issuance or Modification of and draws under Facility LCs in accordance with such LC Issuer’s standard schedule for such charges as in effect from time to time.

SECTION 2.16.5 Administration; Reimbursement by Lenders. Upon receipt from the beneficiary of any Facility LC of any demand for payment under such Facility LC, the applicable LC Issuer shall notify the Administrative Agent and the Administrative Agent shall promptly notify the Borrower and each Lender as to the amount to be paid by such LC Issuer as a result of such demand and the proposed payment date (the “LC Payment Date”). The responsibility of an LC Issuer to the Borrower and each Lender shall be only to determine that the documents (including each demand for payment) delivered under each Facility LC in connection with such presentment shall be in conformity in all material respects with such Facility LC. Each LC Issuer shall endeavor to exercise the same care in the issuance and administration of the Facility LCs as it does with respect to letters of credit in which no participations are granted, it being understood that in the absence of any gross negligence or willful misconduct by the applicable LC Issuer, each Lender shall be unconditionally and irrevocably liable, without regard to the occurrence of the Termination Date (but subject to Section 2.17), the occurrence of any Event of Default or Unmatured Event of Default or any condition precedent whatsoever, to reimburse such LC Issuer on demand for (i) such Lender’s Pro Rata Share of the amount of each payment made by such LC Issuer under any Facility LC to the extent such amount is not reimbursed by the Borrower pursuant to Section 2.16.6, plus (ii) interest on the foregoing amount to be reimbursed by such Lender, for each day from the date of such LC Issuer’s demand for such reimbursement (or, if such demand is made after 11:00 A.M., New York City time, on such day, from the next succeeding Business Day) to the date on which such Lender pays the amount to be reimbursed by it, at a rate of interest per annum equal to the Federal Funds Rate for the first three days and, thereafter, at the Base Rate.

SECTION 2.16.6 Reimbursement by Borrower. The Borrower shall be irrevocably and unconditionally obligated to reimburse the applicable LC Issuer on or before the applicable LC Payment Date for any amount to be paid by such LC Issuer upon any drawing under any Facility LC issued for the account of the Borrower, without presentment, demand, protest or other formalities of any kind; provided that neither the Borrower nor any Lender shall hereby be precluded from asserting any claim for direct (but not consequential) damages suffered by the Borrower or such Lender to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of the applicable LC Issuer in determining whether a request presented under any Facility LC complied with the terms of such Facility LC or (ii) the applicable LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. If the Borrower fails to reimburse fully the applicable LC Issuer by 12:00 noon, New York City time, on an LC Payment Date, such LC Issuer shall promptly notify the Administrative Agent. Upon receipt of such notice, the Administrative Agent shall promptly notify each Lender of such LC Payment Date, the amount of the unpaid Reimbursement Obligations and such Lender’s Pro Rata Share thereof. In such event, the Borrower shall be deemed to have requested Base Rate

Advances to be disbursed on the applicable LC Payment Date in an amount equal to the unpaid Reimbursements Obligations, without regard to the minimum and multiples specified for Base Rate Advances in Section 2.02(a)(v), but subject to the conditions set forth in Article III. All Reimbursement Obligations that are not fully refinanced by the making of Base Rate Advances because the Borrower cannot satisfy the conditions set forth in Article III or for any other reason shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the Base Rate plus 2%. The applicable LC Issuer will pay to each Lender ratably in accordance with its Pro Rata Share all amounts received by it from the Borrower for application in payment, in whole or in part, of the Reimbursement Obligations in respect of any Facility LC issued by such LC Issuer, but only to the extent such Lender has made payment to such LC Issuer in respect of such Facility LC pursuant to Section 2.16.5.

SECTION 2.16.7 Obligations Absolute. The Borrower’s obligations under this Section 2.16 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which the Borrower may have against any LC Issuer, any Lender or any beneficiary of a Facility LC. The Borrower agrees with the LC Issuers and the Lenders that the LC Issuers and the Lenders shall not be responsible for, and the Reimbursement Obligations in respect of any Facility LC shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among the Borrower, any of its Affiliates, the beneficiary of any Facility LC or any financing institution or other party to whom any Facility LC may be transferred or any claims or defenses whatsoever of the Borrower or of any of its Affiliates against the beneficiary of any Facility LC or any such transferee. No LC Issuer shall be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Facility LC. The Borrower agrees that any action taken or omitted by any LC Issuer or any Lender under or in connection with any Facility LC and the related drafts and documents, if done without gross negligence or willful misconduct, shall be binding upon the Borrower and shall not put the applicable LC Issuer or any Lender under any liability to the Borrower. Nothing in this Section 2.16.7 is intended to limit the right of the Borrower to make a claim against an LC Issuer for damages as contemplated by the proviso to the first sentence of Section 2.16.6.

SECTION 2.16.8 Actions of LC Issuers. Each LC Issuer shall be entitled to rely, and shall be fully protected in relying, upon any Facility LC, draft, writing, resolution, notice, consent, certificate, affidavit, letter, facsimile, message, statement, order or other document believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by such LC Issuer. An LC Issuer shall be fully justified in failing or refusing to take any action under this Agreement unless it shall first have received such advice or concurrence of the Majority Lenders as it reasonably deems appropriate or it shall first be indemnified to its reasonable satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Notwithstanding any other

provision of this Section 2.16, an LC Issuer shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Majority Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Lenders and any future holder of a participation in any Facility LC.

SECTION 2.16.9 Indemnification. The Borrower hereby agrees to indemnify and hold harmless each Lender, each LC Issuer and the Administrative Agent, and their respective directors, officers, agents and employees, from and against any claim, damage, loss, liability, cost or expense which such Lender, such LC Issuer or the Administrative Agent may incur (or which may be claimed against such Lender, such LC Issuer or the Administrative Agent by any Person whatsoever) by reason of or in connection with the issuance, execution and delivery or transfer of or payment or failure to pay under any Facility LC or any actual or proposed use of any Facility LC, including any claim, damage, loss liability, cost or expense which the applicable LC Issuer may incur by reason of or in connection with (i) the failure of any other Lender to fulfill or comply with its obligations to such LC Issuer hereunder (but nothing herein contained shall affect any right the Borrower may have against any defaulting Lender) or (ii) by reason of or on account of such LC Issuer issuing any Facility LC that specifies that the term “Beneficiary” included therein includes any successor by operation of law of the named Beneficiary, but which Facility LC does not require that any drawing by any such successor Beneficiary be accompanied by a copy of a legal document, satisfactory to such LC Issuer, evidencing the appointment of such successor Beneficiary; provided that the Borrower shall not be required to indemnify any Lender, any LC Issuer or the Administrative Agent for any claim, damage, loss, liability, cost or expense to the extent, but only to the extent, caused by (x) the willful misconduct or gross negligence of an LC Issuer in determining whether a request presented under any Facility LC complied with the terms of such Facility LC or (y) an LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. Nothing in this Section 2.16.9 is intended to limit the obligations of the Borrower under any other provision of this Agreement.

SECTION 2.16.10 Lenders’ Indemnification. Each Lender shall, ratably in accordance with its Pro Rata Share, indemnify the applicable LC Issuer, its Affiliates and their respective directors, officers, agents and employees (to the extent not reimbursed by the Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or willful misconduct or such LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of the Facility LC) that such indemnitees may suffer or incur in connection with this Section 2.16 or any action taken or omitted by such indemnitees hereunder.

SECTION 2.16.11 Rights as a Lender. In its capacity as a Lender, each LC Issuer shall have the same rights and obligations as any other Lender.

SECTION 2.17.1 Extension Requests. The Borrower may, not more than two (2) times, by notice to the Administrative Agent (which shall promptly notify each Lender) not earlier than 60 and not later than 30 days prior to any anniversary of the Effective Date (each, an “Anniversary Date”), request that each Lender extend such Lender’s scheduled Termination Date then in effect (the “Existing Termination Date”) for an additional year from the Existing Termination Date, it being understood that the Termination Date shall not be later than February 16, 2013 as a result of any such request.

SECTION 2.17.2 Lender Elections to Extend. Each Lender, acting in its sole and individual discretion, shall, by notice to the Administrative Agent given not later than the date (the “Notice Date”) that is 20 days prior to the applicable Anniversary Date, notify the Administrative Agent whether such Lender agrees to the requested extension of the Termination Date (each Lender that determines not to so extend its Termination Date, a “Declining Lender”). Any Lender that does not advise the Administrative Agent on or before the Notice Date that it has agreed to extend the Existing Termination Date shall be deemed to be a Declining Lender.

SECTION 2.17.3 Notification by Administrative Agent. The Administrative Agent shall notify the Borrower of each Lender’s determination under this Section no later than the date 15 days prior to the applicable Anniversary Date.

SECTION 2.17.4 Additional Commitment Lenders. The Borrower shall have the right, at any time after a Lender has become a Declining Lender, to require such Declining Lender to assign and delegate its rights and obligations hereunder to one or more existing Lenders or other financial institutions that have agreed to assume such rights and obligations (each an “Additional Commitment Lender”) pursuant to, and in accordance with the requirements of, Section 8.07.

SECTION 2.17.5 Minimum Extension Requirement. If (and only if) the total of the Commitments of the Lenders (including Additional Commitment Lenders) that have agreed so to extend their Termination Date (each an “Extending Lender”) shall be more than 50% of the Aggregate Commitment Amount in effect immediately prior to the applicable Anniversary Date, then, effective as of such date, the Termination Date of each Extending Lender (including any applicable Additional Commitment Lender) shall be (i) the first anniversary of the Existing Termination Date, in the case of the first extension; or (ii) the second anniversary of the Existing Termination Date, in the case of the second extension (except that, in either case, if such date is not a Business Day, such Termination Date as so extended shall be the next preceding Business Day).

SECTION 2.17.6 Conditions to Effectiveness of Extensions. Notwithstanding the foregoing, no extension of the Termination Date pursuant to this Section shall be effective unless:

(a) no Event of Default or Unmatured Event of Default shall have occurred and be continuing on the date of such extension and after giving effect thereto; and

(b) the representations and warranties of the Borrower contained in this Agreement are true and correct on and as of the date of such extension and after giving effect thereto, as though made on and as of such date (or, if any such representation or warranty is expressly stated to have been made as of a specific date, as of such specific date).

SECTION 2.17.7 Effect of Termination Date for some but not all Lenders. If the scheduled Termination Date for one or more Lenders (each an “Exiting Lender”) occurs on a date that is not the Termination Date for all Lenders, then on such Termination Date (a) the Borrower shall repay all amounts payable to the Exiting Lenders in accordance with Section 2.05, (b) the Commitments of the Exiting Lenders, and the participations of the Exiting Lenders in Facility LCs, shall terminate and (c) the Pro Rata Shares and the participations in Facility LCs of the remaining Lenders shall be redetermined pro rata in accordance with their respective Commitment Amounts after giving effect to the terminations described in clause (b) above; provided that if an Event of Default or Unmatured Event of Default exists on such Termination Date and either (i) the Borrower fails to pay in full all amounts payable to the Exiting Lenders or (ii) the Majority Lenders so request, then the participations of the Exiting Lenders in Facility LCs shall not terminate and no redetermination of the participations of the Lenders in Facility LCs shall be made until the earlier of the first Business Day after such Termination Date on which no Event of Default or Unmatured Event of Default exists and the date specified by the Majority Lenders in a notice to the Administrative Agent (which shall promptly advise each Lender). Nothing in the proviso clause to the preceding sentence shall affect the termination of the Commitment of an Exiting Lender on the relevant Termination Date (except with respect to such Exiting Lender’s participation in Facility LCs) or any Exiting Lender’s right to demand immediate repayment of all amounts owed to such Exiting Lender by the Borrower hereunder and to pursue remedies with respect thereto. Further, if at any time after the relevant Termination Date (x) the Borrower has not paid all principal, interest, facility fees and utilization fees payable to one or more Exiting Lenders hereunder and (y) the Lenders (excluding any Exiting Lender) elect to make Advances, then all proceeds of such Advances shall be applied to pay the amounts owed by the Borrower to such Exiting Lenders (ratably based upon the amounts owed to such Lenders) until such principal, interest, facility fees and utilization fees have been paid in full.

SECTION 2.18 Optional Increase in Commitments. The Borrower may, at any time after the first Anniversary Date occurring after the Effective Date, by means of a letter delivered to the Administrative Agent substantially in the form of Exhibit C, request that the Aggregate Commitment Amount be increased by an aggregate amount (for all such increases) not exceeding $500,000,000 by (a) increasing the Commitment Amount of one or more Lenders that have agreed to such increase (in their sole discretion) and/or (b) adding one or more commercial banks or other Persons as a party hereto (each an “Additional Lender”) with a Commitment Amount in an amount agreed to by any such Additional Lender; provided that (i) any increase in the Aggregate Commitment Amount shall be in an aggregate amount of $25,000,000 or a higher integral multiple of $1,000,000; (ii) no Additional Lender shall be added as a party hereto without the written consent of the Administrative Agent, the Swingline Lenders and the LC Issuers (which consents shall not be unreasonably withheld) or if an Event of Default or an

Unmatured Event of Default exists; and (iii) the Borrower may not request an increase in the Aggregate Commitment Amount unless the Borrower has delivered to the Administrative Agent (with a copy for each Lender) a certificate (x) stating that any applicable governmental authority has approved such increase, (y) attaching evidence, reasonably satisfactory to the Administrative Agent, of each such approval and (z) stating that the representations and warranties contained in Section 4.01 are correct on and as of the date of such certificate as though made on and as of such date and that no Event of Default or Unmatured Event of Default exists on such date. Any increase in the Aggregate Commitment Amount pursuant to this Section 2.18 shall be effective three Business Days after the date on which the Administrative Agent has received and accepted the applicable increase letter in the form of Annex 1 to Exhibit C (in the case of an increase in the Commitment Amount of an existing Lender) or assumption letter in the form of Annex 2 to Exhibit C (in the case of the addition of a commercial bank or other Person as a new Lender). The Administrative Agent shall promptly notify the Borrower and the Lenders of any increase in the Aggregate Commitment Amount pursuant to this Section 2.18 and of the Commitment Amount and Pro Rata Share of each Lender after giving effect thereto. The Borrower shall prepay any Advances outstanding on the Increase Effective Date (and pay any additional amounts required pursuant to Section 8.04(b)) to the extent necessary to keep the outstanding Advances ratable among the Lenders in accordance with any revised Pro Rata Shares arising from any non-ratable increase in the Commitment Amounts under this Section 2.18; provided that, notwithstanding any other provision of this Agreement, the Administrative Agent, the Borrower and each increasing Lender and Additional Lender, as applicable, may make arrangements satisfactory to such parties to cause an increasing Lender or an Additional Lender to temporarily hold risk participations in the outstanding Advances of the other Lenders (rather than fund its Pro Rata Share of all outstanding Advances concurrently with the applicable increase) with a view toward minimizing breakage costs and transfers of funds in connection with any increase in the Aggregate Commitment Amount. To the extent that any increase pursuant to this Section 2.18 is not expressly authorized pursuant to resolutions or consents delivered pursuant to Section 3.01(b)(i), the Borrower shall, prior to the effectiveness of such increase, deliver to the Administrative Agent a certificate signed by an authorized officer of the Borrower certifying and attaching the resolutions or consents that have been adopted to approve or consent to such increase.

SECTION 3.01 Conditions Precedent to Effectiveness. This Agreement (including the Commitments of the Lenders and the obligations of the Borrower hereunder) shall become effective if, on or before October 19, 2007, all of the following conditions precedent have been satisfied:

(iii) A certificate signed by either the chief financial officer, principal accounting officer or treasurer of the Borrower stating that (A) the representations and warranties contained in Section 4.01 are correct on and as of the date of such certificate as though made on and as of such date and (B) no Event of Default or Unmatured Event of Default has occurred and is continuing on the date of such certificate; and

Promptly upon the occurrence thereof, the Administrative Agent shall notify the Borrower, the Lenders and the LC Issuers as to the Effective Date.

SECTION 3.02 Conditions Precedent to All Credit Extensions. The obligation of each Lender to make any Advance and of each LC Issuer to issue or modify any Facility LC shall be

(A) the representations and warranties of the Borrower contained in Section 4.01 (excluding the representations and warranties set forth in Section 4.01(e)(ii) and the first sentence of Section 4.01(f)) are correct on and as of the date of such Credit Extension, before and after giving effect to such Credit Extension and, in the case of the making of Advances, the application of the proceeds therefrom, as though made on and as of such date; and

(B) no event has occurred and is continuing, or would result from such Credit Extension or, in the case of the making of Advances, from the application of the proceeds therefrom, that constitutes an Event of Default or Unmatured Event of Default with respect to the Borrower.

The Lenders agree to indemnify the Administrative Agent (to the extent not reimbursed by the Borrower), ratably according to their respective Pro Rata Shares, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of this Agreement or any action taken or omitted by the Administrative Agent under this Agreement, provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s gross negligence or willful misconduct. Without limiting the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its Pro Rata Share of any out-of-pocket expenses (including reasonable counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that such expenses are reimbursable by the Borrower but for which the Administrative Agent is not reimbursed by the Borrower.

SECTION 7.06 Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower and may be removed at any time with or without cause by the Majority Lenders. Upon any such resignation or removal, the Majority Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Majority Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of resignation or the Majority Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be a commercial bank described in clause (i) or (ii) of the definition of “Eligible Assignee” having a combined capital and surplus of at least $150,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. Notwithstanding the foregoing, if no Event of Default or Unmatured Event of Default shall have occurred and be continuing, then no successor Administrative Agent shall be appointed under this Section 7.06 without the prior written consent of the Borrower, which consent shall not be unreasonably withheld or delayed.

SECTION 7.07 Documentation Agents, Syndication Agent and Co-Lead Arrangers. The titles “Documentation Agent,” “Syndication Agent” and “Co-Lead Arranger” are purely

honorific, and no Person designated as a “Documentation Agent,” a “Syndication Agent” or a “Co-Lead Arranger” shall have any duties or responsibilities in such capacity.

SECTION 8.01 Amendments, Etc. No amendment or waiver of any provision of this Agreement, nor consent to any departure by the Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Majority Lenders and, in the case of an amendment, the Borrower, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided that no amendment, waiver or consent shall, unless in writing and signed by all Lenders (other than any Lender that is the Borrower or an Affiliate thereof), do any of the following: (a) waive or amend any of the conditions specified in Section 3.01 or 3.02, (b) increase or extend the Commitments of the Lenders (other than pursuant to Section 2.17 or 2.18) or subject the Lenders to any additional obligations, (c) reduce the principal of, or interest on, any Advance, any Reimbursement Obligation or any fees or other amounts payable hereunder, (d) postpone any date fixed for any payment of principal of, or interest on, any Advance, any Reimbursement Obligation or any fees or other amounts payable hereunder, (e) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Advances, or the number of Lenders, that shall be required for the Lenders or any of them to take any action hereunder, (f) amend this Section 8.01 or (g) waive or amend any provision regarding pro rata sharing or otherwise relates to the distribution of payments among Lenders; provided, further, that (i) no amendment, waiver or consent shall, unless in writing and signed by the Administrative Agent, in addition to the Lenders required above to take such action, affect the rights or duties of the Administrative Agent under this Agreement; and (ii) no amendment, waiver or consent shall, unless in writing and signed by the applicable LC Issuer, in addition to the Lenders required above to take such action, affect the rights or duties of such LC Issuer under this Agreement.

SECTION 8.02 Notices, Etc. All notices and other communications provided for hereunder shall be in writing (including facsimile transmission) and mailed, sent by facsimile or delivered, if to the Borrower, at 440 South LaSalle Street, Suite 3300, Chicago, IL 60605, Attention: Chief Financial Officer, facsimile: (312) 394-2867, with copies to it at the same address, Attention: General Counsel, facsimile (312) 394-5433; if to any Lender, at its Domestic Lending Office specified in its Administrative Questionnaire or in the Assignment and Acceptance pursuant to which it became a Lender; and if to the Administrative Agent, at its address at JPMorgan Chase Bank, N.A., JPMorgan Loan Services, 1111 Fannin St., 10th Floor, Houston, TX 77002, Attention: Rebecca Camarena, facsimile: (713) 750-2553, with copies to, JPMorgan Chase Bank, N.A., 270 Park Avenue, 5th Floor, New York, NY 10017, Attention: Michael DeForge, facsimile: (212) 270-3089 or, as to each party, at such other address as shall be designated by such party in a written notice to the other parties.

SECTION 8.03 No Waiver; Remedies. No failure on the part of any Lender, any LC Issuer or the Administrative Agent to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

(a) The Borrower agrees to pay on demand all costs and expenses incurred by the Administrative Agent and the Co-Lead Arrangers in connection with the preparation, execution, delivery, administration, syndication, modification and amendment of this Agreement and the other documents to be delivered hereunder, including the reasonable fees, internal charges and out-of-pocket expenses of counsel (including in-house counsel) for the Administrative Agent and the Co-Lead Arrangers with respect thereto and with respect to advising the Administrative Agent and the Co-Lead Arrangers as to their respective rights and responsibilities under this Agreement. The Borrower further agrees to pay on demand all costs and expenses, if any (including counsel fees and expenses of outside counsel and of internal counsel), incurred by the Administrative Agent, any LC Issuer or any Lender in connection with the collection and enforcement (whether through negotiations, legal proceedings or otherwise) of the Borrower’s obligations under this Agreement and the other documents to be delivered by the Borrower hereunder, including reasonable counsel fees and expenses in connection with the enforcement of rights under this Section 8.04(a).

(b) If any payment of principal of, or any conversion of, any Eurodollar Advance is made other than on the last day of the Interest Period for such Advance, as a result of a payment or conversion pursuant to Section 2.09 or 2.12 or acceleration of the maturity of the Advances pursuant to Section 6.01 or for any other reason, the Borrower shall, upon demand by any Lender (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender any amount required to compensate such Lender for any additional loss, cost or expense which it may reasonably incur as a result of such payment or conversion, including any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance.

(c) The Borrower agrees to indemnify and hold each Lender, each LC Issuer, each Agent and each of their respective Affiliates, officers, directors, partners, agents and employees (each, an “Indemnified Person”) harmless from and against any claim, damage, loss, liability, cost or expense (including reasonable attorney’s fees and expenses, whether or not such Indemnified Person is named as a party to any proceeding or is otherwise subjected to judicial or legal process arising from any such proceeding) that any of them may pay or incur arising out of or relating to this Agreement or the transactions contemplated hereby, or the use by the Borrower or any Subsidiary of the proceeds of any Advance; provided that the Borrower shall not be liable for any portion of any such claim, damage, loss, liability, cost or expense resulting from such Indemnified Person’s gross negligence or willful misconduct as determined in a final non-appealable order of a court of competent jurisdiction. The Borrower’s obligations under this Section 8.04(c) shall survive the repayment of all amounts owing by the Borrower to the Lenders and the Administrative Agent under this Agreement and the termination of the Commitments. If

and to the extent that the obligations of the Borrower under this Section 8.04(c) are unenforceable for any reason, the Borrower agrees to make the maximum contribution to the payment and satisfaction thereof which is permissible under applicable law.

SECTION 8.05 Right of Set-off. Upon (i) the occurrence and during the continuance of any Event of Default and (ii) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Administrative Agent to declare the Advances due and payable pursuant to the provisions of Section 6.01, each Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under this Agreement, whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. Each Lender agrees to notify the Borrower promptly after any such set-off and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender under this Section 8.05 are in addition to other rights and remedies (including other rights of set-off) that such Lender may have.

SECTION 8.06 Binding Effect. This Agreement shall be binding upon and inure to the benefit of the Borrower, the Agents and each Lender and their respective successors and assigns, provided that (except as permitted by Section 5.02(b)(iii)) the Borrower shall not have the right to assign rights hereunder or any interest herein without the prior written consent of all Lenders.

(a) Each Lender may, with the prior written consent of the Borrower, each LC Issuer, the Swingline Lenders and the Administrative Agent (which consents shall not be unreasonably withheld or delayed), and if demanded by the Borrower pursuant to Section 8.07(g) shall to the extent required by such Section, assign to one or more banks or other entities all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment, the Advances owing to it and its participation in Facility LCs); provided that (i) each such assignment shall be of a constant, and not a varying, percentage of all of the assigning Lender’s rights and obligations under this Agreement, (ii) the Commitment Amount of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $10,000,000 or, if less, the entire amount of such Lender’s Commitment, and shall be an integral multiple of $1,000,000 or such Lender’s entire Commitment, (iii) each such assignment shall be to an Eligible Assignee, (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with a processing and recordation fee of $3,500 (which shall be payable by one or more of the parties to the Assignment and Acceptance, and not by the Borrower (except in the case of a demand under Section 8.07(g)), and shall not be payable if the assignee is a Federal Reserve Bank), and (v) the consent of the Borrower shall not be required after the occurrence and during the continuance of any Event of Default. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, (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 Assignment and Acceptance, 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 Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement and, in the case of an Assignment and Acceptance 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 (although an assigning Lender shall continue to be entitled to indemnification pursuant to Section 8.04(c)). Notwithstanding anything contained in this Section 8.07(a) to the contrary, (A) the consent of the Borrower, the LC Issuers, the Swingline Lenders and the Administrative Agent shall not be required with respect to any assignment by any Lender to an Affiliate of such Lender or to another Lender and (B) any Lender may at any time, without the consent of the Borrower, any LC Issuer or the Administrative Agent, and without any requirement to have an Assignment and Acceptance executed, assign all or any part of its rights under this Agreement to a Federal Reserve Bank, provided that no such assignment shall release the transferor Lender from any of its obligations hereunder.

(b) By executing and delivering an Assignment and Acceptance, 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 Assignment and Acceptance, 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 this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto; (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 this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Section 4.01(e) and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Administrative 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 this Agreement; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, 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 this Agreement are required to be performed by it as a Lender.

(c) The Administrative Agent shall maintain at its address referred to in Section 8.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitment Amount 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 Administrative 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.

(d) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an assignee representing that it is an Eligible Assignee, the Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit A, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower.

(e) Each Lender may sell participations to one or more banks or other entities (each, a “Participant”) in or to all or a portion of its rights and/or obligations under this Agreement (including all or a portion of its Commitment, the Advances owing to it and its participation in Facility LCs); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the Borrower, the Administrative 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 and (iv) such Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of this Agreement, other than any such amendment, modification or waiver with respect to any Advance or Commitment in which such Participant has an interest that forgives principal, interest or fees or reduces the interest rate or fees payable with respect to any such Advance or Commitment, postpones any date fixed for any regularly scheduled payment of principal of, or interest or fees on, any such Advance or Commitment, extends any Commitment, releases any guarantor of any such Advance or releases any substantial portion of collateral, if any, securing any such Advance.

(f) 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 to preserve the confidentiality of any confidential information relating to the Borrower received by it from such Lender (subject to customary exceptions regarding regulatory requirements, compliance with legal process and other requirements of law).

(g) If any Lender (i) shall make demand for payment under Section 2.11(a), 2.11(b) or 2.14, (ii) shall deliver any notice to the Administrative Agent pursuant to Section 2.12 resulting in the suspension of certain obligations of the Lenders with respect to Eurodollar Advances or (iii) does not consent to an amendment or waiver that requires the consent of all Lenders and has been approved by the Majority Lenders, then (in the case of clause (i)) within 60 days after such demand (if, but only if, such payment demanded under Section 2.11(a), 2.11(b) or 2.14 has been made by the Borrower) or (in the case of clause (ii)) within 60 days after such notice (if such suspension is still in effect) or (in the case of clause (iii)), within 60 days after the date a draft of the applicable amendment or waiver was delivered to such Lender, as the case may be, the Borrower may demand that such Lender assign in accordance with this Section 8.07 to one or more Eligible Assignees designated by the Borrower and reasonably acceptable to the Administrative Agent and the LC Issuers all (but not less than all) of such Lender’s

Commitment, the Advances owing to it and its participation in the Facility LCs and all of its other rights and obligations hereunder within the next succeeding 30 days. 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 Assignee for all of such Lender’s Commitment, Advances and participation in Facility LCs, then such Lender may (but shall not be required to) assign such Commitment and Advances to any other Eligible Assignee in accordance with this Section 8.07 during such period.

(h) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Bank”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Bank to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Advance that such Granting Bank would otherwise be obligated to make pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Advance, (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Advance, the Granting Bank shall be obligated to make such Advance pursuant to the terms hereof. The making of an Advance by an SPC hereunder shall utilize the Commitment of the Granting Bank to the same extent, and as if, such Advance were made by such Granting Bank. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Bank). 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. In addition, notwithstanding anything to the contrary contained in this Section 8.07, any SPC may (i) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Advance to the Granting Bank or to any financial institution (consented to by the Borrower and Administrative Agent, which consents shall be unreasonably withheld or delayed) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Advances and (ii) disclose on a confidential basis any non-public 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(h) may not be amended in any manner which adversely affects a Granting Bank or an SPC without the written consent of such Granting Bank or SPC.

SECTION 8.08 Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

SECTION 8.09 Consent to Jurisdiction; Certain Waivers. (a) THE BORROWER HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY AND OF THE UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT AND THE BORROWER HEREBY

IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVE ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE ADMINISTRATIVE AGENT OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE BORROWER IN THE COURTS OF ANY OTHER JURISDICTION.

(b) EXCEPT AS PROHIBITED BY LAW, EACH PARTY HERETO HEREBY WAIVES ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY LITIGATION ARISING OUT OF OR RELATING TO THIS AGREEMENT ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES.

SECTION 8.10 Waiver of Jury Trial. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 8.11 Execution in Counterparts; Integration. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. This Agreement constitutes the entire agreement and understanding among the parties hereto and supersedes all prior and contemporaneous agreements and understandings, oral or written, relating to the subject matter hereof.

SECTION 8.12 USA PATRIOT ACT NOTIFICATION. The following notification is provided to the Borrower pursuant to Section 326 of the USA Patriot Act of 2001, 31 U.S.C. Section 5318:

IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the government fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to obtain, verify, and record information that identifies each person or entity that opens an account, including any deposit account, treasury management account, loan, other extension of credit, or other financial services product. What this means for the Borrower: When the Borrower

opens an account, the Administrative Agent and the Lenders will ask for the Borrower’s name, tax identification number and business address and other information that will allow the Administrative Agent and the Lenders to identify the Borrower. The Administrative Agent and the Lenders may also ask to see the Borrower’s legal organizational documents or other identifying documents.

In connection with all aspects of the transactions contemplated hereby (including in connection with any amendment, waiver or other modification hereof), the Borrower acknowledges and agrees, and acknowledges its Affiliates’ understanding, that: (i) (A) the arranging and other services regarding this Agreement provided by the Administrative Agent, the other Agents, the Co-Lead Arrangers and the Lenders are arm’s-length commercial transactions between the Borrower and its Affiliates, on the one hand, and the Administrative Agent, the other Agents, the Co-Lead Arrangers and the Lenders on the other hand, (B) the Borrower has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate, and (C) the Borrower is capable of evaluating, and understands and accepts, the terms, risks and conditions of the transactions contemplated hereby; (ii) (A) the Administrative Agent, each other Agent, each Co-Lead Arranger and each Lender is and has been acting solely as a principal and, except as expressly agreed in writing by the relevant parties, has not been, is not, and will not be acting as an advisor, agent or fiduciary for the Borrower or any of its Affiliates, or any other Person and (B) neither the Administrative Agent, any other Agent, any Co-Lead Arranger nor any Lender has any obligation to the Borrower or any of its Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein; and (iii) the Administrative Agent, the other Agents, the Co-Lead Arrangers and the Lenders and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Borrower and its Affiliates, and neither the Administrative Agent, any other Agent, any Co-Lead Arranger nor any Lender has any obligation to disclose any of such interests to the Borrower or its Affiliates. To the fullest extent permitted by law, the Borrower hereby waives and releases any claims that it may have against the Administrative Agent, the other Agents, the Co-Lead Arrangers and the Lenders with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby.

SECTION 8.14 Termination of Existing Credit Facility. JPMorgan Chase Bank, N.A., as administrative agent under the Existing Credit Facility, the Borrower and each Lender that is a party to the Existing Credit Facility (together with other Lenders that are parties to the Existing Credit Facility constitute the “Majority Lenders” under and as defined in the Existing Credit Facility) agree that concurrently with the effectiveness hereof pursuant to Section 3.01, (i) all commitments to extend credit under the Existing Credit Facility shall terminate and be of no further force or effect (without regard to any requirement in the Existing Credit Facility for prior notice of termination of such commitments), and (ii) the Bond Delivery Agreement (as defined in the Existing Credit Facility) shall be terminated and the related First Mortgage Bond (as defined in the Existing Credit Facility) released and surrendered to the Borrower.

The “Applicable Margin,” the “LC Fee Rate,” the “Facility Fee Rate” and the “Utilization Fee Rate” for any day are the respective percentages set forth below in the applicable row under the column corresponding to the Pricing Level that exists on such day:

For purposes of the foregoing, (x) at any time that Debt Ratings are available from each of S&P, Moody’s and Fitch and there is a split among such Debt Ratings, then (i) if any two of such Debt Ratings are in the same level, such level shall apply or (ii) if each of such Debt Ratings is in a different level, the level that is the middle level shall apply and (y) at any time that Debt Ratings are available only from any two of S&P, Moody’s and Fitch and there is a split in such Debt Ratings, then the higher* of such Debt Ratings shall apply, unless there is a split in Debt Ratings of more than one level, in which case the level that is one level higher than the lower Debt Rating shall apply. The Debt Ratings shall be determined from the most recent public announcement of any changes in the Debt Ratings. If the rating system of S&P, Moody’s or Fitch shall change, the Borrower and the Administrative Agent shall negotiate in good faith to amend the definition of “Debt Rating” to reflect such changed rating system and, pending the effectiveness of such amendment (which shall require the approval of the Majority Lenders), the Debt Rating shall be determined by reference to the rating most recently in effect prior to such change. If the Borrower has no Fitch Rating, no Moody’s Rating and no S&P Rating, Pricing Level VIII shall apply.

Credit Agreement dated as of February 22, 2006 among Borrower, various financial institutions and JPMCB, as administrative agent.

This Assignment and Assumption (the “Assignment and Assumption”) is dated as of the Effective Date set forth below and is entered into by and between [Insert name of Assignor] (the “Assignor”) and [Insert name of Assignee] (the “Assignee”).
