“Alternate Base Rate” means, for any day, a rate per annum equal to the higher of (a) the Prime Rate in effect on such day and (b) the Federal Funds Effective Rate in effect on such day plus 1/2 of 1%.

“Applicable Percentage” means, with respect to any Lender, the percentage of the total Commitments represented by such Lender’s Commitment. If the Commitments have terminated or expired, the Applicable Percentages shall be determined based upon the Commitments most recently in effect, giving effect to any assignments.

“Applicable Rate” means, for any day, with respect to any ABR Loan or Eurocurrency Revolving Loan, or with respect to the facility fees payable hereunder, as the case may be, the applicable rate per annum set forth below under the caption “ABR Spread”, “Eurocurrency Spread” or “Facility Fee Rate”, as the case may be, based upon the ratings by Moody’s and/or S&P, respectively, applicable on such date to the Index Debt:

The Borrower’s obligation to reimburse LC Disbursements as provided in paragraph (e) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by any Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor any Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of any Issuing Bank; provided that the foregoing shall not be construed to excuse any Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by such Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or wilful misconduct on the part of an Issuing Bank (as finally determined by a court of competent jurisdiction), each Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank that issued such Letter of Credit may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

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

(h) Interim Interest. If any Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and

32

including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Revolving Loans; provided that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.12(d) shall apply. Interest accrued pursuant to this paragraph shall be for the account of such Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of this Section to reimburse such Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i) Replacement of an Issuing Bank. Any Issuing Bank may be replaced at any time by written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of an Issuing Bank. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.12(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the replaced Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

(j) Cash Collateralization. If (i) any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Lenders with LC Exposure representing greater than 50% of the Dollar Equivalent of the total LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph or (ii) the Borrower is required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 2.11(c), then the Borrower shall deposit in one or more accounts with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, in the case of an Event of Default, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid interest thereon, and in the case of a payment required by Section 2.11(c), the amount of such excess as provided in Section 2.11(c) (in each case, in the relevant currencies in which the Letters of Credit associated with the LC Exposure is denominated); provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (g) or (h) of Article VII. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments

33

shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse each Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with LC Exposure representing greater than 50% of the Dollar Equivalent of the total LC Exposure), be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, and the Borrower is not otherwise required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 2.11(c), such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived.

(k) Existing Letters of Credit. For all purposes hereunder, on the Effective Date, the Existing Letters of Credit shall be deemed issued under this Agreement.

Section 2.07 Funding of Borrowings. (a) Each Lender shall make available for the account of its applicable Lending Office each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds in Dollars, in the case of ABR Loans and Eurocurrency Loans to be funded in Dollars, and in Euros, in the case of Eurocurrency Loans to be funded in Euros, to the applicable Administrative Agent’s Account, by 2:00 p.m., New York City time, with respect to Loans denominated in Dollars, and 2:00 p.m., London time, with respect to Loans denominated in Euros; provided that Swingline Loans shall be made as provided in Section 2.05. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Administrative Agent in New York City and designated by the Borrower in the applicable Borrowing Request or Competitive Bid Request; provided that ABR Revolving Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.06(e) shall be remitted by the Administrative Agent to the Issuing Bank that made such LC Disbursement.

(b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed time of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

34

(c) A payment in Euros shall be deemed to have been made by the Administrative Agent on the date on which it is required to be made under this Agreement if the Administrative Agent has, on or before that date, taken all relevant steps to make that payment. With respect to the payment of any amount denominated in Euros, the Administrative Agent shall not be liable to the Borrower, any Issuing Bank or any of the Lenders in any way whatsoever for any delay, or the consequences of any delay, in the crediting to any account of any amount required by this Agreement to be paid by the Administrative Agent if the Administrative Agent shall have taken all relevant steps to achieve, on the date required by this Agreement, the payment of such amount in immediately available, freely transferable, cleared funds in Euros to the relevant account. In this paragraph, “all relevant steps” means all such steps as may be prescribed from time to time by the regulations or operating procedures of such clearing or settlement system as the Administrative Agent may from time to time determine for the purpose of clearing or settling payments denominated in Euros.

Section 2.08 Interest Elections. (a) Each Revolving Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurocurrency Revolving Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing (including converting a Eurocurrency Borrowing denominated in Dollars into a Eurocurrency Borrowing denominated in Euros) to a different Type or to continue such Borrowing and, in the case of a Eurocurrency Revolving Borrowing, may elect Interest Periods therefor, all as provided in this Section; provided that no Eurocurrency Borrowing denominated in Euros may be continued as, or converted into, a Borrowing denominated in Dollars. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. This Section shall not apply to Competitive Borrowings or Swingline Borrowings, which may not be converted or continued.

(b) To make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Revolving Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by the Borrower.

(c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02:

(i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Borrowing);

35

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurocurrency Borrowing; and

(iv) if the resulting Borrowing is a Eurocurrency Borrowing, the currency of such Borrowing, which shall be either Dollars or Euros, and the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurocurrency Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. If an Interest Election Request requests a Eurocurrency Borrowing but does not specify a currency, then the Borrower shall be deemed to have selected Dollars in the case of a conversion of an ABR Borrowing to a Eurocurrency Borrowing, and in the case of a continuation of a Eurocurrency Borrowing, the same currency in which such Borrowing being continued is denominated.

(d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e) If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurocurrency Revolving Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period, in the case of a Eurocurrency Borrowing denominated in Dollars, such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Revolving Borrowing may be converted to or continued as a Eurocurrency Borrowing and (ii) unless repaid, each Eurocurrency Revolving Borrowing denominated in Dollars shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

Section 2.09 Termination and Reduction of Commitments. (a) Unless previously terminated, the Commitments shall terminate on the Maturity Date.

(b) The Borrower may at any time terminate, or from time to time reduce, the Commitments; provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000 and (ii) the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.11, the Dollar Equivalent (determined on the date by which a notice of an election to terminate or reduce the Commitments is required to be delivered pursuant to Section 2.09(c)) of the sum of the Revolving Credit Exposures plus the aggregate principal amount of outstanding Competitive Loans would exceed the total Commitments.

36

(c) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments.

Section 2.10 Repayment of Loans; Evidence of Debt. (a) The Borrower hereby unconditionally promises to pay (i) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Revolving Loan on the Maturity Date, (ii) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Competitive Loan on the last day of the Interest Period applicable to such Loan and (iii) to the Swingline Lender the then unpaid principal amount of each Swingline Loan on the earlier of the Maturity Date and the first date after such Swingline Loan is made that is the 15th or last day of a calendar month and is at least three Business Days after such Swingline Loan is made; provided that on each date that a Revolving Borrowing or Competitive Borrowing is made, the Borrower shall repay all Swingline Loans then outstanding.

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

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

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

(e) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent (including

37

payable in the currencies in which the Loans may be funded). Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after an increase in such Lender’s Commitment pursuant to Section 2.20 or an increase or reduction in such Lender’s Commitment pursuant to an assignment pursuant to Section 10.04) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

Section 2.11 Prepayment of Loans. (a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with paragraph (b) of this Section; provided that the Borrower shall not have the right to prepay any Competitive Loan without the prior consent of the Lender thereof.

(b) The Borrower shall notify the Administrative Agent (and, in the case of prepayment of a Swingline Loan, the Swingline Lender) by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurocurrency Revolving Borrowing denominated in Dollars, not later than 11:00 a.m., New York City time, three Business Days before the date of prepayment, (ii) in the case of prepayment of a Eurocurrency Revolving Borrowing denominated in Euros, not later than 11:00 a.m., London time, four Business Days before the date of prepayment, (iii) in the case of prepayment of an ABR Revolving Borrowing, not later than 11:00 a.m., New York City time, one Business Day before the date of prepayment, (iv) in the case of prepayment of a Competitive Loan, not later than 11:00 a.m., New York City time, one Business Day before the date of prepayment or (v) in the case of prepayment of a Swingline Loan, not later than 12:00 noon, New York City time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.09, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.09. Promptly following receipt of any such notice relating to a Revolving Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Revolving Borrowing shall be in the Dollar Equivalent (determined on the date by which a notice of prepayment in respect thereof is required to be delivered pursuant to this Section 2.11(b)) of an amount that would be permitted in the case of an advance of a Revolving Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Revolving Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.13 and any break funding payments required by Section 2.16.

(c) If on any Calculation Date, the Dollar Equivalent (determined on such Calculation Date) of (i) the sum of the total Revolving Credit Exposures plus the aggregate principal amount of outstanding Competitive Loans exceeds the total Commitments then in effect or (ii) the sum of the total Revolving Credit Exposures in Euros exceeds the Euro Sublimit, then, in each case, the Borrower shall (A) prepay Borrowings in an aggregate amount equal to such excess and (B) if any excess remains after prepaying Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.06(j). Each such prepayment shall be accompanied by a payment of all accrued and unpaid interest on the Loans prepaid and any

38

break funding payments required by Section 2.16. The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral within five Business Days of written demand from the Administrative Agent. Each prepayment of Borrowings pursuant to (1) clause (i) of this Section 2.11(c) shall be applied, first, ratably to any ABR Borrowings then outstanding, second, to any Eurocurrency Borrowings denominated in Euros then outstanding, and, third, to any Eurocurrency Borrowings denominated in Dollars then outstanding, and if more than one Eurocurrency Borrowing is then outstanding, to each such Eurocurrency Borrowing in order of priority beginning with the Eurocurrency Borrowing with the least number of days remaining in the Interest Period applicable thereto and ending with the Eurocurrency Borrowing with the most number of days remaining in the Interest Period applicable thereto; and (2) clause (ii) of this Section 2.11(c) shall be applied, first, to any Eurocurrency Borrowings denominated in Euros then outstanding, second, ratably to any ABR Borrowings then outstanding, and, third, to any Eurocurrency Borrowings denominated in Dollars then outstanding, and if more than one Eurocurrency Borrowing is then outstanding, to each such Eurocurrency Borrowing in order of priority beginning with the Eurocurrency Borrowing with the least number of days remaining in the Interest Period applicable thereto and ending with the Eurocurrency Borrowing with the most number of days remaining in the Interest Period applicable thereto.

Section 2.12 Fees. (a) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a facility fee, which shall accrue at the Applicable Rate on the daily amount of the Commitment of such Lender (whether used or unused) during the period from and including the Effective Date to but excluding the date on which such Commitment terminates; provided that, if such Lender continues to have any Revolving Credit Exposure after its Commitment terminates, then such facility fee shall continue to accrue on the daily amount of such Lender’s Revolving Credit Exposure from and including the date on which its Commitment terminates to but excluding the date on which such Lender ceases to have any Revolving Credit Exposure. Accrued facility fees shall be payable in arrears on the last day of March, June, September and December of each year and on the date on which the Commitments terminate, commencing on the first such date to occur after the Effective Date; provided that any facility fees accruing after the date on which the Commitments terminate shall be payable on demand. All facility fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last).

(b) The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Rate used to determine the interest rate applicable to Eurocurrency Revolving Loans on the average daily amount of the Dollar Equivalent of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to each Issuing Bank a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of that portion of the Dollar Equivalent of the LC Exposure attributable to such Issuing Bank (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure attributable to such Issuing Bank, as well as

39

such Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable on such last day, commencing on the first such date to occur after the Effective Date; provided that all such fees shall be payable on the date on which the Commitments terminate and any such fees accruing after the date on which the Commitments terminate shall be payable on demand. Any other fees payable to an Issuing Bank pursuant to this paragraph shall be payable within 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last).

(c) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a utilization fee which shall accrue at a per annum rate equal to 0.100% on the daily amount of the Dollar Equivalent of such Lender’s Revolving Credit Exposure during the time the Dollar Equivalent of the sum of the total Revolving Credit Exposures equals or exceeds 50% of the total Commitments. Utilization fees shall be computed on the basis of a year of 360 days and shall be payable in arrears on the last day of March, June, September and December of each year.

(d) The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent.

(e) All fees payable hereunder shall be paid in Dollars on the dates due, in immediately available funds, to the Administrative Agent (or to an Issuing Bank, in the case of fees payable to it) for distribution, in the case of facility fees and participation fees, to the Lenders. Fees paid shall not be refundable under any circumstances. For purposes of calculating fees pursuant to this Section 2.12, the amount of any Revolving Credit Exposure or LC Exposure in Euros shall be the Dollar Equivalent of such amount calculated using the Exchange Rate as of the date such fees are payable as specified in this Section 2.12.

Section 2.13 Interest. (a) The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Rate.

(b) The Loans comprising each Eurocurrency Borrowing shall bear interest (i) in the case of a Eurocurrency Revolving Loan, at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate, or (ii) in the case of a Eurocurrency Competitive Loan, at the LIBO Rate for the Interest Period in effect for such Borrowing plus (or minus, as applicable) the Margin applicable to such Loan.

(c) Each Fixed Rate Loan shall bear interest at the Fixed Rate applicable to such Loan.

(d) Each Swingline Loan shall bear interest at the Swingline Rate plus the Applicable Rate for Eurocurrency Revolving Loans.

40

(e) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section.

(f) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and, in the case of Revolving Loans, upon termination of the Commitments; provided that (i) interest accrued pursuant to paragraph (e)of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Revolving Loan prior to the end of the Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurocurrency Revolving Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(g) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

Section 2.14 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurocurrency Borrowing:

(a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

(b) the Administrative Agent is advised by the Required Lenders (or, in the case of a Eurocurrency Competitive Loan, the Lender that is required to make such Loan) that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Revolving Borrowing to, or continuation of any Revolving Borrowing as, a Eurocurrency Borrowing shall be ineffective and (ii) if any Borrowing Request requests a Eurocurrency Revolving Borrowing, such Borrowing shall be made as an ABR Borrowing and (iii) any request by the Borrower for a

41

Eurocurrency Competitive Borrowing shall be ineffective; provided that (A) if the circumstances giving rise to such notice do not affect all the Lenders, then requests by the Borrower for Eurocurrency Competitive Borrowings may be made to Lenders that are not affected thereby and (B) if the circumstances giving rise to such notice affect only one Type of Borrowings, then the other Type of Borrowings shall be permitted.

Section 2.15 Increased Costs. (a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or any Issuing Bank; or

(ii) impose on any Lender or any Issuing Bank or the London interbank market any other condition affecting this Agreement or Eurocurrency Loans or Fixed Rate Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurocurrency Loan or Fixed Rate Loan (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender or such Issuing Bank of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or such Issuing Bank hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender or such Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered.

(b) If any Lender or any Issuing Bank determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or such Issuing Bank’s capital or on the capital of such Lender’s or such Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by such Issuing Bank, to a level below that which such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such Issuing Bank’s policies and the policies of such Lender’s or such Issuing Bank’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or such Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company for any such reduction suffered.

(c) A certificate of a Lender or an Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or such Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or such Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

42

(d) Failure or delay on the part of any Lender or any Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or an Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender or such Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or such Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

(e) Notwithstanding the foregoing provisions of this Section, a Lender shall not be entitled to compensation pursuant to this Section in respect of any Competitive Loan if the Change in Law that would otherwise entitle it to such compensation shall have been publicly announced prior to submission of the Competitive Bid pursuant to which such Loan was made.

Section 2.16 Break Funding Payments. In the event of (a) the payment of any principal of any Eurocurrency Loan or Fixed Rate Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurocurrency Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurocurrency Loan or Fixed Rate Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.11(b) and is revoked in accordance therewith), (d) the failure to borrow any Competitive Loan after accepting the Competitive Bid to make such Loan, or (e) the assignment of any Eurocurrency Loan or Fixed Rate Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.19, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurocurrency Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for Dollar or Euro (as applicable) deposits of a comparable amount and period from other banks in the Eurocurrency market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

Section 2.17 Taxes. (a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as

43

necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, Lender or Issuing Bank (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 Governmental Authority in accordance with applicable law.

(b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) The Borrower shall indemnify the Administrative Agent, each Lender and each Issuing Bank, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or such Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender or an Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or an Issuing Bank, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate.

Section 2.18 Payments Generally; Pro Rata Treatment; Sharing of Set-offs. (a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.15, Section 2.16 or Section 2.17, or otherwise) on the date when due, in immediately available funds, without set-off or counterclaim, to the applicable Administrative Agent’s Account, in the case of payments in Dollars, prior to 12:00 noon, New York City time, and in the case of payments in Euros, prior to 12:00 noon, London time. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent, except payments to be made directly to an Issuing Bank or

44

the Swingline Lender as expressly provided herein and except that payments pursuant to Section 2.15, Section 2.16, Section 2.17 and Section 10.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person in like funds to the appropriate recipient, for the account of its applicable Lending Office, promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in Dollars, except with respect to Loans denominated in Euros or reimbursement of LC Disbursements in respect of Letters of Credit denominated in Euros, which shall be prepaid or repaid, including interest thereon, in Euros.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Revolving Loans or participations in LC Disbursements or Swingline Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Revolving Loans and participations in LC Disbursements and Swingline Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Revolving Loans and participations in LC Disbursements and Swingline Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Revolving Loans and participations in LC Disbursements and Swingline Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

45

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or any Issuing Bank hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or such Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or such Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or such Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.06(d) or (e), Section 2.07(b) or Section 2.18(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

Section 2.19 Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.15 or Section 2.17, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, or if any Lender defaults in its obligation to fund Loans hereunder or if any Lender shall fail to agree to extend the Maturity Date pursuant to Section 2.21 if the Required Lenders have agreed to do so, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 10.04), all its interests, rights and obligations under this Agreement (other than outstanding Competitive Loans held by it) to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent (and, if a Commitment is being assigned, each Issuing Bank), which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans (other than Competitive Loans) and

46

participations in LC Disbursements and Swingline Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

Section 2.20 Procedures Regarding Increases to the Commitments. (a) So long as no Default or Event of Default has occurred and is continuing, the Borrower may request from time to time, subject to the terms and conditions hereinafter set forth, that the aggregate amount of the Lenders’ Commitments be increased and, in connection therewith, that the Euro Sublimit be increased. Any such request shall be made by written notice to the Administrative Agent; provided, however, that any such notice must be given no later than 60 days prior to the Maturity Date. Each such notice (a “Initial Notice of Commitment Increase”) shall be in the form of Exhibit C-1 and specify therein:

(i) the proposed effective date of such increase to the Lenders’ Commitments, which date (the requested “Commitment Increase Effective Date”) shall be no earlier than forty-five days after receipt by the Administrative Agent of such notice;

(ii) the amount of the requested increase to the Lenders’ Commitments; provided, however, that (A) such increase must be at least $25,000,000 and (B) after giving effect to such requested increase, the aggregate amount of the Lenders’ Commitments shall not exceed $1,500,000,000; and

(iii) the amount of the requested increase to the amount of the Euro Sublimit, if any; provided, however, that the amount by which the Euro Sublimit is increased shall not exceed the amount of the requested increase to the Lenders’ Commitments.

The Administrative Agent shall deliver a copy of such Initial Notice of Commitment Increase to each Lender via facsimile transmission on or before the third Business Day next succeeding the date the Administrative Agent receives such Initial Notice of Commitment Increase. After receipt of the Initial Notice of Commitment Increase, each Lender shall determine, in its sole discretion, whether to participate, and to what extent, if any, in such Commitment increase and shall communicate such decision in writing to the Administrative Agent and the Borrower on or before the eleventh day prior to the proposed Commitment Increase Effective Date.

(b) On the tenth day prior to the proposed Commitment Increase Effective Date, so long as no Default or Event of Default has occurred and is continuing, the Borrower shall deliver to the Administrative Agent a written notice confirming the requested increase in the aggregate amount of the Lenders’ Commitments. Each such notice (a “Notice of Confirmation of Commitment Increase”) shall be in the form of Exhibit C-2 and specify therein:

47

(i) the proposed Commitment Increase Effective Date, which date shall be no earlier than five Business Days after receipt by the Administrative Agent of such Notice of Confirmation of Commitment Increase;

(ii) the amount of the requested increase to the Lenders’ Commitments; provided, however, that (A) such increase must be at least $25,000,000 and (B) after giving effect to such requested increase, the aggregate amount of the Lenders’ Commitments shall not exceed $1,500,000,000;

(iii) the amount of the requested increase to the amount of the Euro Sublimit, if any; provided, however, that the amount by which the Euro Sublimit is increased shall not exceed the amount of the requested increase to the Lenders’ Commitments;

(iv) the identity of each of the then Lenders, if any, which has agreed with the Borrower to increase its Commitment in an amount such that its Applicable Percentage after giving effect to such requested increase will be the same or greater than its Applicable Percentage prior to giving effect to such requested increase (each such Lender being an “Increasing Lender”), each of the other then Lenders, if any, which has agreed to increase its Commitment in an amount such that its Applicable Percentage after giving effect to such a requested increase will be less than its Applicable Percentage prior to giving effect to such requested increase (each such Lender being a “Partially Increasing Lender”) and the identity of each financial institution not already a Lender, if any, which has agreed with the Borrower to become a Lender to effect such requested increase in the aggregate amount of the Lenders’ Commitments (each such financial institution shall be reasonably acceptable to the Administrative Agent and each such financial institution being a “New Lender” and each of the other then Lenders, if any, which has not agreed to increase its Commitment being a “Reducing Lender”); and

(v) the amount of the respective Commitments of the then existing Lenders, such Increasing Lenders, such Partially Increasing Lenders, such Reducing Lenders and such New Lenders from and after the effective date of such increase.

(c) On or before each Commitment Increase Effective Date:

(i) the Borrower, each Increasing Lender, each Partially Increasing Lender and each then New Lender shall execute and deliver to the Administrative Agent for its acceptance, as to form, documentation embodying the provisions of the Notice of Commitment Increase relating to the increase in the aggregate amount of the Lenders’ Commitments to be effected on such Commitment Increase Effective Date; and

(ii) upon acceptance of such documentation by the Administrative Agent, which acceptance shall not be unreasonably withheld, and so long as no Default or Event of Default has occurred and is continuing, (A) the Administrative Agent shall give prompt notice of such acceptance to each Lender, (B) it shall become effective, and each Increasing Lender’s and Partially Increasing Lender’s Commitment shall be increased to the amount specified therein, on such Commitment Increase Effective Date and (C) the Administrative Agent shall record each New Lender’s information in the Register.

48

(d) On each Commitment Increase Effective Date:

(i) each then New Lender and each then Increasing Lender shall, by wire transfer of immediately available funds, deliver to the Administrative Agent such Lenders’ New Funds Amount for such Commitment Increase Effective Date, which amount, for each such Lender, shall constitute Loans made by such Lender to the Borrower pursuant to Section 2.01 on such Commitment Increase Effective Date; and

(ii) the Administrative Agent shall, by wire transfer of immediately available funds, pay to each then Reducing Lender and to each Partially Increasing Lender its Reduction Amount for such Commitment Increase Effective Date, which amount, for each such Lender, shall constitute a prepayment by the Borrower pursuant to Section 2.11, ratably in accordance with the respective principal amounts thereof, of the principal amounts of all then outstanding Loans of such Lender.

The Administrative Agent shall record each then New Lender’s, each then Increasing Lender’s and each then Partially Increasing Lender’s information in the Register. Also effective as of each Commitment Increase Effective Date, each then New Lender and each then Increasing Lender shall be deemed to have purchased and had transferred to it, and each then Reducing Lender and each Partially Increasing Lender shall be deemed to have sold and transferred as provided in Section 2.06(d) to such New Lenders and Increasing Lenders, such undivided interest and participation in such Reducing Lender’s and such Partially Increasing Lender’s interest and participation in all then outstanding Letters of Credit, to the extent necessary so that such undivided interests and participations of all Lenders (including each New Lender) shall accord with their respective Applicable Percentages after giving effect to the increase in the aggregate amount of the Lenders’ Commitments on such Commitment Increase Effective Date.

Section 2.21 Extension of Maturity Date.

(a) Not earlier than 90 days prior to, nor later than 30 days prior to, each anniversary of December 10, 2007, the Borrower may, upon notice to the Administrative Agent (which shall promptly notify the Lenders), request a one-year extension of the Maturity Date then in effect. Within 20 days of delivery of such notice, each Lender shall notify the Administrative Agent whether or not it consents to such extension (which consent may be given or withheld in such Lender’s sole and absolute discretion). Any Lender not responding within the above time period shall be deemed not to have consented to such extension. The Administrative Agent shall promptly notify the Borrower and the Lenders of the Lenders’ responses.

(b) The Maturity Date shall be extended only if the Required Lenders (calculated excluding any Lender in default in its obligation to fund Loans hereunder and prior to giving effect to any replacements of Lenders permitted herein) (the Lenders that so consent being the “Consenting Lenders” and the Lenders that do not consent being the “Non-Consenting

49

Lenders”) have consented thereto. If so extended, the Maturity Date, as to the Consenting Lenders, shall be extended to the same date in the year following the Maturity Date then in effect (such existing Maturity Date being the “Extension Effective Date”). The Administrative Agent and the Borrower shall promptly confirm to the Lenders such extension, specifying the date of such confirmation (the “Extension Confirmation Date”), the Extension Effective Date, and the new Maturity Date (after giving effect to such extension). As a condition precedent to such extension, the Borrower shall deliver to the Administrative Agent a certificate of the Borrower dated as of the Extension Confirmation Date signed by a Responsible Officer of the Borrower (i) certifying and attaching the resolutions adopted by the Borrower approving or consenting to such extension and (ii) certifying that, (A) before and after giving effect to such extension, the representations and warranties contained in Article III made by it are true and correct on and as of the Extension Confirmation Date, except to the extent that such representations and warranties specifically refer to an earlier date, (B) before and after giving effect to such extension no Default exists or will exist as of the Extension Confirmation Date, and (C) since December 31, 2006, no event, development or circumstance that has had a Material Adverse Effect has occurred. The Borrower shall pay to the Administrative Agent for the account of each Non-Consenting Lender the then unpaid principal amount of such Non-Consenting Lender’s Loans outstanding on the Extension Effective Date (and pay any additional amounts required pursuant to Section 2.16). In addition, the Borrower shall prepay any Loans outstanding on the Extension Effective Date (and pay any additional amounts required pursuant to Section 2.16) to the extent necessary to keep outstanding Loans ratable with any revised and new Applicable Percentages of all the Lenders effective as of the Extension Effective Date.

Section 2.22 Dollar Equivalent Determinations.

(a) Not later than 5:00 p.m. (New York time) on each date on which the Dollar Equivalent of any amount in Euros is required to be determined hereunder (other than pursuant to Section 2.23 or except as otherwise expressly provided for herein), the Administrative Agent shall determine the Dollar Equivalent of such amount using the Exchange Rate for such date.

(b) Promptly after the determination of the Dollar Equivalent of any amount in Euros pursuant to this Section 2.22, the Administrative Agent shall promptly notify the Borrower, the Issuing Banks and the Lenders of the results thereof. All determinations by the Administrative Agent of the Exchange Rate and the Dollar Equivalent of any amount shall be deemed to be conclusive absent manifest error.

Section 2.23 Currency Conversion. Notwithstanding anything to the contrary contained herein, if any payment of any obligation shall be made in a currency other than the currency required hereunder, such amount shall be converted into the currency required hereunder at the rate determined by the Administrative Agent, as the rate quoted by it in accordance with methods customarily used by the Administrative Agent for such or similar purposes as the spot rate for the purchase by the Administrative Agent of the required currency with the currency of actual payment through its principal foreign exchange trading office at approximately 11:00 a.m. (local time at such office) two Business Days prior to the effective date of such conversion, provided that the Administrative Agent may obtain such spot rate from another financial institution

50

actively engaged in foreign currency exchange if the Administrative Agent does not then have a spot rate for the required currency. The parties hereto hereby agree, to the fullest extent that they may effectively do so under applicable law, that if for the purposes of obtaining any judgment or award it becomes necessary to convert from any currency other than the currency required hereunder into the currency required hereunder any amount in connection with any obligation hereunder, then the conversion shall be made as provided above on the Business Day before the day on which the judgment or award is given, in the event that there is a change in the applicable conversion rate prevailing between the Business Day before the day on which the judgment or award is given and the date of payment, the Borrower will pay to the Administrative Agent, for the benefit of the Lenders, such additional amounts (if any) as may be necessary, and the Administrative Agent, on behalf of the Lenders, will pay to the Borrower such excess amounts (if any) as result from such change in the rate of exchange, to assure that the amount paid on such date is the amount in such other currency, which when converted at the conversion rate described herein on the date of payment, is the amount then due in the currency required hereunder, and any amount due from the Borrower under this Section 2.23 shall be due as a separate debt and shall not be affected by judgment or award being obtained for any other sum due.

(a) Unless designated as an Unrestricted Subsidiary on Schedule 3.12 as of the date hereof or thereafter, assuming compliance with Section 6.10(b), any Person that becomes a Subsidiary of the MLP or any Restricted Subsidiary shall be classified as a Restricted Subsidiary.

(b) The Borrower may designate by written notification thereof to the Administrative Agent, any Restricted Subsidiary (other than the Borrower or any Guarantor), as an Unrestricted Subsidiary if: (i) prior, and after giving effect, to such designation, no Default would exist and (ii) such designation is deemed to be an Investment in an Unrestricted Subsidiary in an amount equal to the fair market value as of the date of such designation of the MLP’s direct and indirect ownership interest in such Subsidiary and such Investment would be permitted to be made at the time of such designation under Section 6.04(g). Except as provided in this Section 6.10(b), no Restricted Subsidiary may be redesignated as an Unrestricted Subsidiary.

(c) The Borrower may designate any Unrestricted Subsidiary to be a Restricted Subsidiary if after giving effect to such designation: (i) the representations and warranties of the MLP and the Borrower contained in each of the Loan Documents are true and correct on and as of the date of such designation as if made on and as of the date of such designation (or, if stated to have been made expressly as of an earlier date, were true and correct as of such date), (ii) no Default would exist and (iii) the MLP and the Borrower complies with the requirements of Section 5.10.

(d) Notwithstanding the foregoing or anything to the contrary contained herein, for the purposes of this Agreement the Borrower and each Guarantor is a Restricted Subsidiary of the MLP and may not be an Unrestricted Subsidiary.

ARTICLE VIII

MLP Guarantee

Section 8.01 MLP Guarantee.

(a) The MLP, to the maximum extent permitted by applicable law, (i) absolutely, unconditionally and irrevocably, guarantees to the Administrative Agent for the ratable benefit of the Guaranteed Creditors and their respective successors, endorsees, transferees and assigns, the prompt and complete payment and performance by the Borrower when due (whether at the stated maturity, by acceleration or otherwise) of the Borrower Obligations and (ii) indemnifies and holds harmless each Guaranteed Creditor from, and agrees to pay to such Guaranteed Creditor, all reasonable costs and expenses (including reasonable counsel fees and expenses) incurred by such Guaranteed Creditor in enforcing any of its rights under the guarantee contained in this Section 8.01. The MLP agrees that notwithstanding any stay, injunction or other prohibition preventing the payment by the Borrower of all or any portion of the Borrower Obligations and notwithstanding that all or any portion of the Borrower Obligations may be unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving the Borrower, to the maximum extent permitted by applicable law, such Borrower Obligations shall nevertheless be due and payable by the MLP for the purposes of this guarantee at the time such Borrower Obligations would by payable by the Borrower under the provisions of this Agreement. Notwithstanding the foregoing, any enforcement of this guarantee with respect to the rights of any Guaranteed Creditor shall be accomplished by the Administrative Agent acting on behalf of such Guaranteed Creditor. The guarantee contained in this Section 8.01 is a guarantee of payment and not collection, and the liability of the MLP is primary and not secondary. Anything to the contrary notwithstanding, the maximum liability of the MLP under the guarantee provided for in this Article VIII shall in no event exceed the amount which can be guaranteed by the MLP under applicable federal and state laws relating to insolvency of debtors (after giving effect to any right of contribution provided for herein or in any other Loan Document).

(b) The MLP agrees that if the maturity of the Borrower Obligations is accelerated by bankruptcy or otherwise, such maturity shall also be deemed accelerated for the purpose of this guarantee without demand or notice to the MLP. The guarantee contained in this Section 8.01 is a continuing guarantee and shall remain in full force and effect until all the Borrower Obligations and the obligations of the MLP under the guarantee contained in this Section 8.01 shall have been satisfied by payment in full in cash, no Letter of Credit shall be outstanding and the Commitments shall be terminated, notwithstanding that from time to time during the term of this Agreement the Borrower may be free from any Borrower Obligations.

(c) No payment made by the Borrower, the MLP, any other guarantor or any other Person or received or collected by any Guaranteed Creditor from the Borrower, the MLP, any other guarantor or any other Person by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Borrower Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of the MLP hereunder which shall, notwithstanding any such payment (other than any payment made by the Borrower or MLP in respect of the Borrower Obligations or any payment received

70

or collected from the Borrower or MLP in respect of the Borrower Obligations), remain liable for the Borrower Obligations until, subject to Section 8.05, the Borrower Obligations are paid in full in cash, no Letter of Credit shall be outstanding and the Commitments are terminated.

Section 8.02 Subrogation. The MLP shall be subrogated to all the rights of any Guaranteed Creditor against the Borrower in respect of any amounts paid by the MLP pursuant to the provisions of the guarantee contained in Section 8.01; provided, however, that the MLP shall not be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation with respect to any of the Borrower Obligations, nor shall the MLP seek or be entitled to seek any contribution or reimbursement from the Borrower or any other Guarantor (or any other guarantor) in respect of payments made by the MLP hereunder, until all of the Borrower Obligations and the Guarantees thereof shall have been indefeasibly paid in full in cash or discharged. A director, officer, employee or stockholder, as such, of the MLP shall not have any liability for any obligations of the MLP under the guarantee contained in Section 8.01 or any claim based on, in respect of or by reason of such obligations or their creation.

Section 8.03 Amendments, etc. with respect to the Borrower Obligations. The MLP shall remain obligated hereunder notwithstanding that, without any reservation of rights against the MLP and without notice to or further assent by the MLP, any demand for payment of any of the Borrower Obligations made by any Guaranteed Creditor may be rescinded by such Guaranteed Creditor and any of the Borrower Obligations continued, and the Borrower Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by any Guaranteed Creditor, and any Loan Document and any other document executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders or all Lenders, as the case may be) may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by any Guaranteed Creditor for the payment of the Borrower Obligations may be sold, exchanged, waived, surrendered or released. Except as required by applicable law, no Guaranteed Creditor shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Borrower Obligations or for the guarantee contained in Section 8.01 or any property subject thereto.

Section 8.04 Guarantee Absolute and Unconditional. To the fullest extent permitted by applicable law, the MLP hereby (a) waives diligence, presentment, demand of payment, notice of intent to accelerate, notice of acceleration, notice of acceptance, filing of claims with a court in the event of the merger, insolvency or bankruptcy of the Borrower or the MLP, and all demands and notices whatsoever, (b) acknowledges that any agreement, instrument or document evidencing the MLP Obligations may be transferred and that the benefit of its obligations hereunder shall extend to each holder of any agreement, instrument or document evidencing the MLP Obligations without notice to them and (c) covenants that the MLP Obligations will not be discharged except by complete performance thereof. The MLP further agrees that to the fullest extent permitted by applicable law, if at any time all or any part of any payment theretofore applied by any Person to any of the MLP Obligations is, or must be, rescinded or returned for any reason whatsoever, including without limitation, the insolvency, bankruptcy or

71

reorganization of the MLP, such MLP Obligations shall, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence notwithstanding such application, and the MLP Obligations shall continue to be effective or be reinstated, as the case may be, as though such application had not been made.

To the fullest extent permitted by applicable law, the obligations of the MLP under this guarantee shall be as aforesaid full, irrevocable, unconditional and absolute and shall not be impaired, modified, discharged, released or limited by any occurrence or condition whatsoever, including, without limitation, (i) any compromise, settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in, any of the obligations and liabilities of the Borrower or the MLP contained in any of the Borrower Obligations or this Agreement, (ii) any impairment, modification, release or limitation of the liability of the Borrower, the MLP or any of their estates in bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present or future provision of any applicable bankruptcy law, as amended, or other statute or from the decision of any court, (iii) the assertion or exercise by the Borrower or the MLP of any rights or remedies under any of the Borrower Obligations or this Agreement or their delay in or failure to assert or exercise any such rights or remedies, (iv) the assignment or the purported assignment of any property as security for any of the Borrower Obligations, including all or any part of the rights of the Borrower or the MLP under this Agreement, (v) the extension of the time for payment by the Borrower or the MLP of any payments or other sums or any part thereof owing or payable under any of the terms and provisions of any of the Borrower Obligations or this Agreement or of the time for performance by the Borrower or the MLP of any other obligations under or arising out of any such terms and provisions or the extension or the renewal of any thereof, (vi) the modification or amendment (whether material or otherwise) of any duty, agreement or obligation of the Borrower or the MLP set forth in this Agreement, (vii) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of, or other similar proceeding affecting, the Borrower or any of the MLP or any of their respective assets, or the disaffirmance of any of the Borrower Obligations, or this Agreement in any such proceeding, (viii) the release or discharge of the Borrower or the MLP from the performance or observance of any agreement, covenant, term or condition contained in any of such instruments by operation of law, (ix) the unenforceability of any of the Borrower Obligations or this Agreement, (x) any change in the name, business, capital structure, corporate existence, or ownership of the Borrower or the MLP or any other person or entity liable on the obligations guaranteed hereby, (xi) the existence of any collateral or other guaranty, or any exchange, release or non-perfection of any collateral or other guaranty, or (xii) any other circumstance which might otherwise constitute a defense available to, or a legal or equitable discharge of, a surety or the MLP.

Section 8.05 Reinstatement. To the maximum extent permitted by applicable law, the guarantee contained in Section 8.01 shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Borrower Obligations is rescinded or must otherwise be restored or returned by any Guaranteed Creditor upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Borrower or the MLP, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Borrower or the MLP or any substantial part of its property, or otherwise, all as though such payments had not been made.

72

Section 8.06 Payments. The MLP hereby guarantees that payments hereunder will be paid to the Administrative Agent without set-off or counterclaim and without deduction for any taxes and in immediately available funds and in the relevant currency at the Administrative Agent’s payment office at the address provided in Section 10.01 of this Agreement.

ARTICLE IX

The Administrative Agent

Each of the Lenders and the Issuing Banks hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto.

The bank serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not the Administrative Agent hereunder.

The Administrative Agent shall not have any duties or obligations except those expressly set forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing as directed by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 10.02), and (c) except as expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 10.02) or in the absence of its own gross negligence or wilful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

73

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Banks and the Borrower. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Banks, appoint a successor Administrative Agent which shall be a Lender and a commercial bank with an office in New York, New York and having a combined capital and surplus of at least $500,000,000, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall 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 hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 10.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the

74

Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder.

None of the Syndication Agent, the Co-Documentation Agents or the Co-Managing Agents shall have any duties, responsibilities or liabilities under this Agreement or the other Loan Documents other than their duties, responsibilities and liabilities in their capacity as Lenders hereunder.

The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be limited to particular notices or communications.

(c) Any party hereto may change its address or telecopy number for notices and other communications hereunder by notice to the other parties hereto. All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given on the date of receipt.

Section 10.02 Waivers; Amendments. (a) No failure or delay by the Administrative Agent, any Issuing Bank or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Banks and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any Lender or any Issuing Bank may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor the Subsidiary Guaranty nor any provision hereof or thereof may be waived, amended or modified (except as expressly set forth herein or therein) except pursuant to an agreement or agreements in writing entered into by the Borrower, the MLP and the Required Lenders or by the Borrower, the MLP and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv)change Section 2.18(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) waive or amend Section 2.21, Section 4.01,

76

Article VIII or release the MLP from its obligations hereunder or release any other Guarantor from a Subsidiary Guaranty (except as expressly set forth in the Subsidiary Guaranty) without the written consent of each Lender or (vi) change any of the provisions of this Section or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, any Issuing Bank or the Swingline Lender hereunder without the prior written consent of the Administrative Agent, such Issuing Bank or the Swingline Lender, as the case may be.

Section 10.03 Expenses; Indemnity; Damage Waiver. (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by any Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iii) all out-of-pocket expenses incurred by the Administrative Agent, any Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, any Issuing Bank or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, or in connection with the Loans made or Letters of Credit issued hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit.

(b) The Borrower shall indemnify the Administrative Agent, each Issuing Bank and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by any Issuing Bank to honor a demand for payment under a Letter of Credit issued by it if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or wilful misconduct of such Indemnitee.

77

(c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent, any Issuing Bank or the Swingline Lender under paragraph (a) or (b) of this Section (and without limiting the Borrower’s obligation to do so), each Lender severally agrees to pay to the Administrative Agent, such Issuing Bank or the Swingline Lender, as the case may be, such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent, such Issuing Bank or the Swingline Lender in its capacity as such.

(d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

(e) All amounts due under this Section shall be payable not later than 5 Business Days after written demand therefor.

Section 10.04 Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of any Issuing Bank that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of any Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Banks and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

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

78

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

(B) the Administrative Agent; provided that no consent of the Administrative Agent shall be required for an assignment of any Commitment to an assignee that is a Lender with a Commitment immediately prior to giving effect to such assignment; and

(C) each Issuing Bank.

(ii) Assignments shall be subject to the following additional conditions:

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

(B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement; provided that this clause shall not be construed to prohibit the assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of one Class of Commitments or Loans;

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

(D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

For the purposes of this Section 10.04(b), the term “Approved Fund” has the following meaning:

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

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest

79

assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 2.15, Section 2.16, Section 2.17 and 10.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 10.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

(iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Issuing Banks and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the Issuing Banks and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant to Section 2.06(d) or (e), Section 2.07(b), Section 2.18(d) or 10.03(c), the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c)(i) Any Lender may, without the consent of the Borrower, the Administrative Agent, any Issuing Bank or the Swingline Lender, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent, the Issuing Banks and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender

80

shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 10.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Section 2.15, Section 2.16, Section 2.17 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.08 as though it were a Lender; provided such Participant agrees to be subject to Section 2.18(c) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.15 or Section 2.17 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.17 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.17(e) as though it were a Lender.

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

Section 10.05 Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, any Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Section 2.15, Section 2.16, Section 2.17 and 10.03 and Article IX shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof.

Section 10.06 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which

81

shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other required parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 10.07 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

Section 10.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates 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 obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower or the MLP against any of and all the obligations of the Borrower or the MLP now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

Section 10.09 Governing Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in accordance with and governed by the law of the State of New York.

(b) The Borrower and the MLP each hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court 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, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the Administrative Agent, any Issuing Bank or any Lender may otherwise have to bring any action or proceeding relating to this Agreement against the Borrower or its properties in the courts of any jurisdiction.

82

(c) The Borrower and the MLP each hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 10.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

Section 10.10 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 10.11 Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

Section 10.12 Confidentiality. Each of the Administrative Agent, the Issuing Banks and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, any Issuing Bank or any Lender on a nonconfidential basis from a source other than the Borrower. For the purposes of this Section, “Information” means all information received from the

83

Borrower relating to the Borrower or its business, other than any such information that is available to the Administrative Agent, any Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Borrower; provided that, in the case of information received from the Borrower after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

Section 10.13 Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

Section 10.14 Limitation of Liability. Neither the General Partner nor the general partner(s) of the MLP shall be liable for (a) the obligations of the Borrower under this Agreement or (b) the obligations of the MLP under this Agreement, including in each case, without limitation, by reason of any payment obligation imposed by governing state partnership statutes and any provision of the applicable limited partnership agreement of the Borrower or the MLP that requires such General Partner or general partner(s), as the case may be, to restore a capital account deficit.

Section 10.15 USA PATRIOT Act. Each Lender that is subject to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”) hereby notifies the Borrower that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act.
