2.2 Procedure for Term Loan Borrowing. The Borrower shall give the Administrative Agent irrevocable notice in the form of a Borrowing Request (which notice must be received by the Administrative Agent prior to 1:00 P.M., New York City time, (a) three Business Days prior to the anticipated Closing Date, in the case of Eurodollar Loans, or (b) one Business Day prior to the anticipated Closing Date, in the case of ABR Loans) requesting that the Term Lenders make the Term Loans on the Closing Date

and specifying the amount to be borrowed. Upon receipt of such notice the Administrative Agent shall promptly notify each Term Lender thereof. Not later than 12:00 Noon, New York City time, on the Closing Date each Term Lender shall make available to the Administrative Agent at the Funding Office an amount in immediately available funds equal to the Term Loan or Term Loans to be made by such Lender. The Administrative Agent shall credit the account of the Borrower on the books of such office of the Administrative Agent with the aggregate of the amounts made available to the Administrative Agent by the Term Lenders in immediately available funds.

(a) The Tranche A Term Loan of each Tranche A Lender shall mature in 23 consecutive quarterly installments and on October 5, 2011, in an amount equal to such Lender’s Tranche A Term Percentage multiplied by the amount set forth below opposite such installment:

(b) The Tranche B Term Loan of each Tranche B Lender shall mature in 27 consecutive quarterly installments and on the Tranche B Term Loan Maturity Date, in an amount equal to such Lender’s Tranche B Term Percentage multiplied by the amount set forth below opposite such installment:

(a) Subject to the terms and conditions hereof, each Revolving Lender severally agrees to make revolving credit loans (“Revolving Loans”) to the Borrower from time to time during the Revolving Commitment Period in an aggregate principal amount at any one time outstanding which, when added to such Lender’s Revolving Percentage of the sum of (i) the LC Obligations then outstanding and (ii) the aggregate principal amount of the Swingline Loans then outstanding, does not exceed the amount of such Lender’s Revolving Commitment; provided that no more than $100.0 million may be borrowed on the Closing Date to fund the Acquisition. During the Revolving Commitment Period the Borrower may use the Revolving Commitments by borrowing, prepaying the Revolving Loans in whole or in part, and reborrowing, all in accordance with the terms and conditions hereof. The Revolving Loans may from time to time be Eurodollar Loans or ABR Loans, as determined by the Borrower and notified to the Administrative Agent in accordance with Sections 2.5 and 2.12.

(b) The Borrower shall repay all outstanding Revolving Loans on the Revolving Termination Date.

2.5 Procedure for Revolving Loan Borrowing. The Borrower may borrow under the Revolving Commitments during the Revolving Commitment Period on any Business Day, provided that the Borrower shall give the Administrative Agent irrevocable notice in the form of a Borrowing Request (which notice must be received by the Administrative Agent prior to 2:00 P.M., New York City time, (a) three Business Days prior to the requested Borrowing Date, in the case of Eurodollar Loans, or (b) one Business Day prior to the requested Borrowing Date, in the case of ABR Loans) (provided that any such notice of a borrowing of ABR Loans under the Revolving Facility to finance payments required by Section 3.5 may be given not later than 1:00 P.M., New York City time, on the date of the proposed borrowing), specifying (i) the amount and Type of Revolving Loans to be borrowed, (ii) the requested Borrowing

Date and (iii) in the case of Eurodollar Loans, the respective amounts of each such Type of Loan and the respective lengths of the initial Interest Period therefor. Each borrowing under the Revolving Commitments shall be in an amount equal to (x) in the case of ABR Loans, $1,000,000 or a whole multiple thereof (or, if the then aggregate Available Revolving Commitments are less than $1,000,000, such lesser amount) and (y) in the case of Eurodollar Loans, $5,000,000 or a whole multiple of $1,000,000 in excess thereof; provided, that the Swingline Lender may request, on behalf of the Borrower, borrowings under the Revolving Commitments that are ABR Loans in other amounts pursuant to Section 2.7. Upon receipt of any such notice from the Borrower, the Administrative Agent shall promptly notify each Revolving Lender thereof. Each Revolving Lender will make the amount of its pro rata share of each borrowing available to the Administrative Agent for the account of the Borrower at the Funding Office prior to 12:00 Noon, New York City time, on the Borrowing Date requested by the Borrower in funds immediately available to the Administrative Agent. Such borrowing will then be made available to the Borrower by the Administrative Agent crediting the account of the Borrower on the books of such office with the aggregate of the amounts made available to the Administrative Agent by the Revolving Lenders and in like funds as received by the Administrative Agent.

(a) Subject to the terms and conditions hereof, the Swingline Lender agrees to make a portion of the credit otherwise available to the Borrower under the Revolving Commitments from time to time after the Closing Date and during the Revolving Commitment Period by making swing line loans (“Swingline Loans”) to the Borrower; provided that (i) the aggregate principal amount of Swingline Loans outstanding at any time shall not exceed the Swingline Commitment then in effect and (ii) the Borrower shall not request, and the Swingline Lender shall not make, any Swingline Loan if, after giving effect to the making of such Swingline Loan, the aggregate amount of the Available Revolving Commitments would be less than zero. During the Revolving Commitment Period, the Borrower may use the Swingline Commitment by borrowing, repaying and reborrowing, all in accordance with the terms and conditions hereof. Swingline Loans shall be ABR Loans only.

(b) The Borrower shall repay to the Swingline Lender the then unpaid principal amount of each Swingline Loan on the earlier of the Revolving Termination 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 two Business Days after such Swingline Loan is made; provided that on each date that a Revolving Loan is borrowed, the Borrower shall repay all Swingline Loans then outstanding.

(a) To request a Swingline Loan, the Borrower shall notify the Administrative Agent of such request by telephone (confirmed by telecopy of a Borrowing Request), not later than 2:00 P.M., New York City time, on the day (which shall be a Business Day during the Revolving Commitment Period) of a proposed Swingline Loan. Each such notice shall be irrevocable and shall specify the requested date (which shall be a Business Day) and amount of the requested Swingline Loan. The Administrative Agent will promptly advise the Swingline Lender of any such notice received from the Borrower. The Swingline Lender shall make each Swingline Loan available to the Borrower by means of a credit to the general deposit account of the Borrower with the Swingline Lender (or, in the case of a Swingline Loan made to finance the reimbursement of an LC Disbursement as provided in Section 3.5, by remittance to the Issuing Bank) by 4:00 p.m., New York City time, on the requested date of such Swingline Loan. Each borrowing under the Swingline Commitment shall be in an amount equal to $500,000 or a whole multiple of $100,000 in excess thereof.

(b) The Swingline Lender, at any time and from time to time in its sole and absolute discretion may, on behalf of the Borrower (which hereby irrevocably directs the Swingline Lender to act on its behalf), on one Business Day’s notice given by the Swingline Lender no later than 2:00 P.M., New York City time, request each Revolving Lender to make, and each Revolving Lender hereby agrees to make, a Revolving Loan, in an amount equal to such Revolving Lender’s Revolving Percentage of the aggregate amount of the Swingline Loans; provided that, notwithstanding the foregoing, no Revolving Lender shall be obligated to make any Revolving Loan if after giving effect to the making of such Revolving Loan the outstanding amount of Revolving Extensions of Credit of such Lender exceed such Lender’s Revolving Commitment (the “Refunded Swingline Loans”) outstanding on the date of such notice, to repay the Swingline Lender. Each Revolving Lender shall make the amount of such Revolving Loan available to the Administrative Agent at the Funding Office in immediately available funds, not later than 10:00 A.M., New York City time, one Business Day after the date of such notice. The proceeds of such Revolving Loans shall be immediately made available by the Administrative Agent to the Swingline Lender for application by the Swingline Lender to the repayment of the Refunded Swingline Loans. The Borrower irrevocably authorizes the Swingline Lender to charge the Borrower’s accounts with the Administrative Agent (up to the amount available in each such account) in order to immediately pay the amount of such Refunded Swingline Loans to the extent amounts received from the Revolving Lenders are not sufficient to repay in full such Refunded Swingline Loans.

(c) If prior to the time a Revolving Loan would have otherwise been made pursuant to Section 2.7(b), one of the events described in Section 8.1(g) shall have occurred and be continuing with respect to the Borrower or if for any other reason, as determined by the Swingline Lender in its sole discretion, Revolving Loans may not be made as contemplated by Section 2.7(b), each Revolving Lender shall, on the date such Revolving Loan was to have been made pursuant to the notice referred to in Section 2.7(b), purchase for cash an undivided participating interest in the then outstanding Swingline Loans by paying to the Swingline Lender an amount (the “Swingline Participation Amount”) equal to (i) such Revolving Lender’s Revolving Percentage times (ii) the sum of the aggregate principal amount of Swingline Loans then outstanding that were to have been repaid with such Revolving Loans.

(d) Whenever, at any time after the Swingline Lender has received from any Revolving Lender such Lender’s Swingline Participation Amount, the Swingline Lender receives any payment on account of the Swingline Loans, the Swingline Lender will distribute to such Lender its Swingline Participation Amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s participating interest was outstanding and funded and, in the case of principal and interest payments, to reflect such Lender’s pro rata portion of such payment if such payment is not sufficient to pay the principal of and interest on all Swingline Loans then due); provided, however, that in the event that such payment received by the Swingline Lender is required to be returned, such Revolving Lender will return to the Swingline Lender any portion thereof previously distributed to it by the Swingline Lender.

(e) Each Revolving Lender’s obligation to make the Loans referred to in Section 2.7(b) and to purchase participating interests pursuant to Section 2.7(c) shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any setoff, counterclaim, recoupment, defense or other right that such Revolving Lender or the Borrower may have against the Swingline Lender, the Borrower or any other Person for any reason whatsoever; (ii) the occurrence or continuance of a Default or an Event of Default or the failure to satisfy any of the other conditions specified in Section 5; (iii) any adverse change in the condition (financial or otherwise) of the Borrower; (iv) any breach of this Agreement or any other Loan Document by the Borrower, any other Loan Party or any other Revolving Lender; or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.

(a) The Borrower agrees to pay to the Administrative Agent for the account of each Revolving Lender a commitment fee for the period from and including the date hereof to the last day of the Revolving Commitment Period, computed at the Commitment Fee Rate on the average daily amount of the Available Revolving Commitment of such Lender during the period for which payment is made, payable quarterly in arrears on each Fee Payment Date, commencing on the first such date to occur after the date hereof.

(b) The Borrower agrees to pay to the Administrative Agent the fees in the amounts and on the dates previously agreed to in writing by the Borrower and the Administrative Agent.

(c) The Borrower will pay a fee on all outstanding Letters of Credit at a per annum rate equal to the Applicable Margin then in effect with respect to Eurodollar Loans under the Revolving Facility, shared ratably among the Revolving Lenders and payable quarterly in arrears on each Fee Payment Date after the issuance date. In addition, the Borrower shall pay to the Issuing Lender for its own account a fronting fee of 0.125% per annum on the undrawn and unexpired amount of each Letter of Credit, payable quarterly in arrears on each Fee Payment Date after the issuance date.

(d) In addition to the foregoing fees, the Borrower shall pay or reimburse the Issuing Lender for such normal and customary costs and expenses (including issuance fees) as are incurred or charged by the Issuing Lender in issuing, negotiating, effecting payment under, amending or otherwise administering any Letter of Credit.

(e) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Lender, 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.

2.9 Termination or Reduction of Revolving Commitments. The Borrower shall have the right, upon not less than three Business Days’ notice to the Administrative Agent, to terminate the Revolving Commitments or, from time to time, to reduce the amount of the Revolving Commitments; provided that no such termination or reduction of Revolving Commitments shall be permitted if, after giving effect thereto and to any prepayments of the Revolving Loans and Swingline Loans made on the effective date thereof, the Total Revolving Extensions of Credit would exceed the Total Revolving Commitments. Any such reduction shall be in an amount equal to $1,000,000, a whole multiple thereof, or the remaining aggregate amount of the Revolving Commitments, and shall reduce permanently the Revolving Commitments then in effect.

2.10 Optional Prepayments. The Borrower may at any time and from time to time prepay the Loans, in whole or in part, without premium or penalty, upon irrevocable notice delivered to the Administrative Agent no later than 2:00 P.M., New York City time, three Business Days prior thereto, in the case of Eurodollar Loans, and no later than 2:00 P.M., New York City time, one Business Day prior thereto, in the case of ABR Loans, which notice shall specify the date and amount of prepayment, the installment or installments of the respective tranches of the Loans to be repaid and whether the prepayment is of Eurodollar Loans or ABR Loans (it being understood that the Borrower may elect to prepay one tranche of Term Loans without prepaying another); provided, that in the case of Swingline Loans notice may be given no later than 2:00 p.m. New York City time on the date of prepayment; and provided further that if a Eurodollar Loan is prepaid on any day other than the last day of the Interest Period applicable thereto, the Borrower shall also pay any amounts owing pursuant to Section 2.20. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof. If any such notice is

given, the amount specified in such notice shall be due and payable on the date specified therein, together with (except in the case of Revolving Loans that are ABR Loans and Swingline Loans) accrued interest to such date on the amount prepaid. Partial prepayments of a tranche of Term Loans or of Revolving Loans shall be in an aggregate principal amount of $1,000,000 or a whole multiple thereof. Partial prepayments of Swingline Loans shall be in an aggregate principal amount of $100,000 or a whole multiple thereof.

(a) If any Redeemable Preferred Interests or Debt shall be issued or incurred by any Group Member (excluding any Debt incurred in accordance with Section 7.2 (other than Section 7.2(q) and, to the extent clause (x) thereof is not complied with, Section 7.2(l)) or any initial cash proceeds that are related to a financing of a fixed principal amount of Receivables Assets or any initial incremental cash proceeds that are related to financing an increased fixed principal amount of Receivables Assets shall be received by Borrower or any of its subsidiaries in connection with a Permitted Receivables Financing, an amount equal to 100% of the Net Cash Proceeds thereof shall be applied on the date of such issuance or incurrence toward the prepayment of the Term Loans and the Revolving Loans as set forth in Section 2.11(d). If any Capital Stock other than Redeemable Preferred Interests or Excluded Issuances shall be issued by the Borrower, an amount equal to 50% of the Net Cash Proceeds thereof shall be applied on the date of such issuance toward the prepayment of the Term Loans and the Revolving Loans as set forth in Section 2.11(d); provided that this sentence shall not be applicable to any issuance of Capital Stock of the Borrower if the Leverage Ratio as of the most recent Measurement Period was less than 3.25 to 1.00.

(b) If on any date any Group Member shall receive Net Cash Proceeds from any Asset Sale or Recovery Event then, unless a Reinvestment Notice shall be delivered in respect thereof, such Net Cash Proceeds shall be applied on such date toward the prepayment of the Term Loans and the Revolving Loans as set forth in Section 2.11(d); provided, that, notwithstanding the foregoing, on each Reinvestment Prepayment Date, an amount equal to the Reinvestment Prepayment Amount with respect to the relevant Reinvestment Event shall be applied toward the prepayment of the Term Loans and the Revolving Loans as set forth in Section 2.11(d).

(c) If, for any Fiscal Year of the Borrower commencing with the Fiscal Year ending December 31, 2005, there shall be Excess Cash Flow, the Borrower shall, on the relevant Excess Cash Flow Application Date, apply the ECF Percentage of such Excess Cash Flow toward the prepayment of the Term Loans and the reduction of the Revolving Commitments as set forth in Section 2.11(d). Each such prepayment and commitment reduction shall be made on a date (an “Excess Cash Flow Application Date”) no later than five days after the earlier of (i) the date on which the financial statements of the Borrower referred to in Section 6.1(b), for the fiscal year with respect to which such prepayment is made, are required to be delivered to the Lenders and (ii) the date such financial statements are actually delivered.

The application of any prepayment pursuant to this Section 2.11 shall be made, first, to ABR Loans and, second, to Eurodollar Loans. Each prepayment of the Loans under this Section 2.11 (except in the case of Revolving Loans that are ABR Loans and Swingline Loans) shall be accompanied by accrued interest to the date of such prepayment on the amount prepaid.

(e) Notwithstanding anything to the contrary in Section 2.11(d) or 2.17, with respect to the amount of any mandatory prepayment described in Section 2.11 that is allocated to Tranche B Term Loans (such amount, the “Tranche B Prepayment Amount”), at any time when Tranche A Term Loans remain outstanding, the Borrower will, in lieu of applying such amount to the prepayment of Tranche B

Term Loans, as provided in Section 2.11(d) above, on the date specified in Section 2.11 for such prepayment, give the Administrative Agent telephonic notice (promptly confirmed in writing) requesting that the Administrative Agent prepare and provide to each Tranche B Lender a notice (each, a “Prepayment Option Notice”) as described below.

On the Mandatory Prepayment Date, (i) the Borrower shall pay to the relevant Tranche B Lenders the aggregate amount necessary to prepay that portion of the outstanding relevant Term Loans as described above in respect of which such Lenders have accepted prepayment (it being understood that a failure to respond to a Prepayment Option Notice shall be deemed an acceptance of the prepayment referenced therein) and (ii) the Borrower shall pay to the Tranche A Lenders an amount equal to the portion of the Tranche B Prepayment Amount not accepted by the relevant Lenders, and such amount shall be applied to the prepayment of the Tranche A Term Loans; provided that if after the application of amounts pursuant to clause (ii), any portion of the Tranche B Prepayment Amount not accepted by the Tranche B Term Loan Lenders shall remain, such amount shall be used to prepay the Tranche B Term Loans on a pro rata basis.

(ii) In the event of any partial reduction of the Revolving Commitments, then (x) at or prior to the effective date of such reduction, the Administrative Agent shall notify the Borrower and the Revolving Lenders of the sum of the Revolving Extensions of Credit after giving effect thereto and (y) if the sum of the Revolving Extensions of Credit would exceed the aggregate amount of Revolving Commitments after giving effect to such reduction, then the Borrower shall, on the date of such reduction, first, repay or prepay Swingline Loans, second, repay or prepay Revolving Loans and third, replace outstanding Letters of Credit or cash collateralize outstanding Letters of Credit in accordance with the procedures set forth in Section 3.10, in an aggregate amount sufficient to eliminate such excess.

(iii) In the event that the sum of all Lenders’ Revolving Extensions of Credit exceeds the Revolving Commitments then in effect, the Borrower shall, without notice or demand, immediately first, repay or prepay Swingline Loans, second, repay or prepay Revolving Loans, and third, replace outstanding Letters of Credit or cash collateralize outstanding Letters of Credit in accordance with the procedures set forth in Section 3.10, in an aggregate amount sufficient to eliminate such excess.

(iv) In the event that the aggregate LC Obligations exceeds the LC Commitment then in effect, the Borrower shall, without notice or demand, immediately replace outstanding Letters of Credit or cash collateralize outstanding Letters of Credit in accordance with the procedures set forth in Section 3.10, in an aggregate amount sufficient to eliminate such excess.

(g) Prepayment Premium.

(a) The Borrower may elect from time to time to convert Eurodollar Loans to ABR Loans by giving the Administrative Agent prior irrevocable notice of such election pursuant to an Interest Election Request no later than 2:00 P.M., New York City time, on the Business Day preceding the proposed conversion date, provided that any such conversion of Eurodollar Loans may only be made on the last day of an Interest Period with respect thereto. The Borrower may elect from time to time to convert ABR Loans to Eurodollar Loans by giving the Administrative Agent prior irrevocable notice of such election no later than 2:00 P.M., New York City time, on the third Business Day preceding the proposed conversion date (which notice shall specify the length of the initial Interest Period therefor), provided that no ABR Loan under a particular Facility may be converted into a Eurodollar Loan when any Event of Default has occurred and is continuing and the Administrative Agent or the Majority Facility Lenders in respect of such Facility have determined in its or their sole discretion not to permit such conversions. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof.

(b) Any Eurodollar Loan may be continued as such upon the expiration of the then current Interest Period with respect thereto by the Borrower giving irrevocable notice to the Administrative Agent pursuant to an Interest Election Request, in accordance with the applicable provisions of the term “Interest Period” set forth in Section 1.1, of the length of the next Interest Period to be applicable to such Loans, provided that no Eurodollar Loan under a particular Facility may be continued as such when any Event of Default has occurred and is continuing and the Administrative Agent has or the Majority Facility Lenders in respect of such Facility have determined in its or their sole discretion not to permit such continuations, and provided, further, that if the Borrower shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso such Loans shall be automatically converted to ABR Loans on the last day of such then expiring Interest Period. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof.

2.13 Limitations on Eurodollar Tranches. Notwithstanding anything to the contrary in this Agreement, all borrowings, conversions and continuations of Eurodollar Loans and all selections of Interest Periods shall be in such amounts and be made pursuant to such elections so that, (a) after giving effect thereto, the aggregate principal amount of the Eurodollar Loans comprising each Eurodollar Tranche shall be equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof and (b) no more than fifteen Eurodollar Tranches shall be outstanding at any one time.

(a) Each Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to the Eurodollar Rate determined for such day plus the Applicable Margin.

(b) Each ABR Loan shall bear interest at a rate per annum equal to the ABR plus the Applicable Margin.

(c) Upon the occurrence and during the continuance of an Event of Default under Section 8.1(a), (b) or (g), if all or a portion of the principal amount of any Loan or Reimbursement Obligation or any interest payable on any Loan or Reimbursement Obligation or any commitment fee or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or

otherwise), such overdue amount shall bear interest at a rate per annum equal to the greater or (i) the rate then applicable to ABR Loans under the relevant Facility plus 2% (or, in the case of any such other amounts that do not relate to a particular Facility, the rate then applicable to ABR Loans under the Revolving Facility plus 2%) and (ii) the actual rate applicable to such amount plus 2%, from the date of such non-payment until such amount is paid in full (after as well as before judgment).

(d) Interest shall be payable in arrears on each Interest Payment Date, provided that interest accruing pursuant to paragraph (c) of this Section shall be payable from time to time on demand.

(a) Interest and fees payable pursuant hereto shall be calculated on the basis of a 360-day year for the actual days elapsed, except that, with respect to ABR Loans the rate of interest on which is calculated on the basis of the Prime Rate, the interest thereon shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed. The Administrative Agent shall as soon as practicable notify the Borrower and the relevant Lenders of each determination of a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a change in the ABR or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Borrower and the relevant Lenders of the effective date and the amount of each such change in interest rate.

(b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrower, deliver to the Borrower a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to Section 2.14(a).

2.16 Inability to Determine Interest Rate. If prior to the first day of any Interest Period:

(a) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or

(b) the Administrative Agent shall have received notice from the Majority Facility Lenders in respect of the relevant Facility that the Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the Borrower and the relevant Lenders as soon as practicable thereafter. If such notice is given, (x) any Eurodollar Loans under the relevant Facility requested to be made on the first day of such Interest Period shall be made as ABR Loans, (y) any Loans under the relevant Facility that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as ABR Loans and (z) any outstanding Eurodollar Loans under the relevant Facility shall be converted, on the last day of the then-current Interest Period, to ABR Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans under the relevant Facility shall be made or continued as such, nor shall the Borrower have the right to convert Loans under the relevant Facility to Eurodollar Loans.

(a) Each borrowing by the Borrower from the Lenders hereunder, each payment by the Borrower on account of any commitment fee and any reduction of the Commitments of the Lenders shall be made pro rata according to the respective Tranche A Term Percentages, Tranche B Term Percentages or Revolving Percentages, as the case may be, of the relevant Lenders.

(b) Each payment (including each prepayment) by the Borrower on account of principal of and interest on the Term Loans shall be made pro rata according to the respective outstanding principal amounts of the Term Loans then held by the Term Lenders (except as otherwise provided in Section 2.11(e) and except that an optional prepayment pursuant to Section 2.10 need only be made pro rata according to the respective outstanding principal amounts of the Term Loans of the applicable tranche being prepaid then held by the Term Lenders). The amount of each principal prepayment of the Term Loans shall be applied to reduce the then remaining installments of the Tranche A Term Loans and Tranche B Term Loans, as the case may be, pro rata based upon the respective then remaining principal amounts thereof. Amounts prepaid on account of the Term Loans may not be reborrowed.

(c) Each payment (including each prepayment) by the Borrower on account of principal of and interest on the Revolving Loans shall be made pro rata according to the respective outstanding principal amounts of the Revolving Loans then held by the Revolving Lenders.

(d) All payments (including prepayments) to be made by the Borrower hereunder, whether on account of principal, interest, fees or otherwise, shall be made without setoff or counterclaim and shall be made prior to 1:00 P.M., New York City time, on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Funding Office, in Dollars and in immediately available funds. The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal pursuant to the preceding two sentences, interest thereon shall be payable at the then applicable rate during such extension.

(e) Unless the Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon, at a rate equal to the greater of (i) the Federal Funds Effective Rate and (ii) a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation, for the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this paragraph shall be conclusive in the absence of manifest error. If such Lender’s share of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days after such Borrowing Date, the Administrative Agent shall also be entitled to recover such amount with interest thereon at the rate per annum applicable to ABR Loans under the relevant Facility, on demand, from the Borrower.

(f) Unless the Administrative Agent shall have been notified in writing by the Borrower prior to the date of any payment due to be made by the Borrower hereunder that the Borrower will not make such payment to the Administrative Agent, the Administrative Agent may assume that the Borrower is making such payment, and the Administrative Agent may, but shall not be required to, in reliance upon such assumption, make available to the Lenders their respective pro rata shares of a corresponding amount. If such payment is not made to the Administrative Agent by the Borrower within three Business Days after such due date, the Administrative Agent shall be entitled to recover, on demand, from each Lender to which any amount which was made available pursuant to the preceding sentence, such amount with interest thereon at the rate per annum equal to the daily average Federal Funds Effective Rate. Nothing herein shall be deemed to limit the rights of the Administrative Agent or any Lender against the Borrower.

(a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof:

(i) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any Application or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by Section 2.19 and changes in the rate of tax on the overall net income of such Lender);

(ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in the determination of the Eurodollar Rate; or

and the result of any of the foregoing is to increase the cost to such Lender, by an amount that such Lender deems to be material, of making, converting into, continuing or maintaining Eurodollar Loans or issuing or participating in Letters of Credit, or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Borrower shall promptly pay such Lender, upon its demand, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this paragraph, it shall promptly notify the Borrower (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled.

(b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation Controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof shall have the effect of reducing the rate of return on such Lender’s or such corporation’s capital as a consequence of its obligations hereunder or under or in respect of any Letter of

Credit to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or such corporation’s policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrower (with a copy to the Administrative Agent) of a written request therefor, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender or such corporation for such reduction.

(c) Each request by a Lender for the payment of an additional amount under this Section 2.18 shall be accompanied by a certificate showing in reasonable detail the method of calculation and the allocation (which shall be reasonable) thereof. Such certificate as to any additional amounts payable pursuant to this Section submitted by any Lender to the Borrower (with a copy to the Administrative Agent) shall be conclusive in the absence of manifest error. Notwithstanding anything to the contrary in this Section, the Borrower shall not be required to compensate a Lender pursuant to this Section for any amounts incurred more than six months prior to the date that such Lender notifies the Borrower of such Lender’s intention to claim compensation therefor; provided that, if the circumstances giving rise to such claim have a retroactive effect, then such six-month period shall be extended to include the period of such retroactive effect. The obligations of the Borrower pursuant to this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

(a) All payments made by any Loan Party under this Agreement or any other Loan Document shall be made free and clear of, and without deduction or withholding for or on account of, any Taxes, excluding overall net income taxes and franchise taxes (imposed in lieu of net income taxes) imposed on the Administrative Agent or any Lender by a jurisdiction as a result of the recipient being organized or having its principal office or, in the case of any Lender, having its applicable lending office in such jurisdiction. If any such non-excluded Taxes (“Non-Excluded Taxes”) or Other Taxes are required to be withheld or deducted from any amounts payable (which shall include deductions applicable to additional sums payable under this Section) to the Administrative Agent or any Lender hereunder, the amounts so payable to the Administrative Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent or such Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement, provided, however, that the Borrower shall not be required to increase any such amounts payable to any Lender with respect to any Non-Excluded Taxes (i) that are attributable to such Lender’s failure to comply with the requirements of paragraph (e) or (f) of this Section or (ii) that are United States federal withholding taxes imposed on amounts payable to such Lender at the time such Lender becomes a party to this Agreement (“Additional Excluded Taxes”), except to the extent that such Lender’s assignor (if any) was entitled, at the time of assignment, to receive additional amounts from the Borrower with respect to such Non-Excluded Taxes pursuant to this paragraph; provided that this subclause (ii) shall not apply to any Tax imposed on a Lender in connection with an interest or participation in any Loan or other obligation that such Lender was required to acquire pursuant to Section 11.7.

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

(c) The Borrower and the Guarantors shall indemnify the Administrative Agent, or the affected Lender, as applicable, within 10 days after demand therefor, for the full amount of any Non-Excluded Taxes or Other Taxes, but excluding Additional Excluded Taxes (including Non-Excluded Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section, but excluding Additional Excluded Taxes) paid by the Administrative Agent or such Lender, as the case may

be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Non-Excluded 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 (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Non-Excluded 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) Each Lender that is not a “U.S. Person” as defined in Section 7701(a)(30) of the Code (a “Non-U.S. Lender”) shall deliver to the Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased) two copies of either U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI, or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest”, a statement substantially in the form of Exhibit J and a Form W-8BEN, or any subsequent versions thereof or successors thereto, properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by the Borrower under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to this Agreement (or, in the case of any Participant, on or before the date such Participant purchases the related participation). In addition, each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Non-U.S. Lender. Each Non-U.S. Lender shall promptly notify the Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of certification adopted by the U.S. taxing authorities for such purpose). Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall not be required to deliver any form pursuant to this paragraph that such Non-U.S. Lender is not legally able to deliver.

(f) A Lender that is entitled to an exemption from or reduction of non-U.S. 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 or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate, provided that such Lender is legally entitled to complete, execute and deliver such documentation and in such Lender’s sole judgment such completion, execution or submission would not be materially disadvantageous to such Lender and would not materially prejudice the legal position of such Lender.

(g) If the Administrative Agent or any Lender determines, in its sole discretion, that it has received a refund of any Non-Excluded Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 2.19, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.19 with respect to the Non-Excluded Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any

penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary, in no event will any Lender be required to pay any amount to the Borrower the payment of which would place such Lender in a less favorable net after-tax position than such Lender would have been in if the additional amounts giving rise to such refund of any Non-Excluded Taxes or Other Taxes had never been paid. This paragraph shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

(h) The agreements in this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

2.20 Indemnity. The Borrower agrees to indemnify each Lender for, and to hold each Lender harmless from, any loss or expense that such Lender may sustain or incur as a consequence of (a) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (b) default by the Borrower in making any prepayment of or conversion from Eurodollar Loans after the Borrower has given a notice thereof in accordance with the provisions of this Agreement or (c) the making of a prepayment of Eurodollar Loans on a day that is not the last day of an Interest Period with respect thereto. Such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest that would have accrued on the amount so prepaid, or not so borrowed, converted or continued, for the period from the date of such prepayment or of such failure to borrow, convert or continue to the last day of such Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Loans provided for herein (excluding, however, the Applicable Margin included therein, if any) over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurodollar market. A certificate as to any amounts payable pursuant to this Section submitted to the Borrower by any Lender shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

2.21 Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.18 or 2.19(a) with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans affected by such event with the object of avoiding the consequences of such event; provided, that such designation is made on terms that, in the sole judgment of such Lender, cause such Lender and its lending office(s) to suffer no economic, legal or regulatory disadvantage, and provided, further, that nothing in this Section shall affect or postpone any of the obligations of the Borrower or the rights of any Lender pursuant to Section 2.18 or 2.19(a).

2.22 Replacement of Lenders. The Borrower shall be permitted to replace any Lender that (a) requests reimbursement for amounts owing pursuant to Section 2.18 or 2.19(a), (b) defaults in its obligation to make Loans hereunder, with a replacement financial institution or (c) is replaced pursuant to the third paragraph of Section 11.1; provided that (i) such replacement does not conflict with any Requirement of Law, (ii) no Event of Default shall have occurred and be continuing at the time of such replacement, (iii) if applicable, prior to any such replacement, such Lender shall not have taken appropriate action under Section 2.21 so as to eliminate the continued need for payment of amounts owing pursuant to Section 2.18 or 2.19(a), (iv) the replacement financial institution shall purchase, at par, all Loans and

other amounts owing to such replaced Lender on or prior to the date of replacement, (v) the Borrower shall be liable to such replaced Lender under Section 2.20 if any Eurodollar Loan owing to such replaced Lender shall be purchased other than on the last day of the Interest Period relating thereto, (vi) the replacement financial institution, if not already a Lender, shall be reasonably satisfactory to the Administrative Agent, (vii) the replaced Lender shall be obligated to make such replacement in accordance with the provisions of Section 11.6 (provided that the Borrower shall be obligated to pay the registration and processing fee referred to therein) and by its execution of this Agreement each Lender hereby authorizes the Administrative Agent to act as its agent in executing any documents to replace such Lender in accordance with this Section 2.22, (viii) until such time as such replacement shall be consummated, the Borrower shall pay all additional amounts (if any) required pursuant to Section 2.18 or 2.19(a), as the case may be, and (ix) any such replacement shall not be deemed to be a waiver of any rights that the Borrower, the Administrative Agent or any other Lender shall have against the replaced Lender.

(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 Revolving Termination Date, (ii) to the Administrative Agent for the account of each Lender the Term Loans in accordance with Section 2.3 and (iii) to the Swingline Lender the then unpaid principal amount of each Swingline Loan in accordance with Section 2.6(b).

(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 Facility 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. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 11.6) 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).

(a) The Borrower may by written notice to the Administrative Agent elect to request (x) prior to the Revolving Termination Date, an increase to the existing Revolving Commitments and/or (y) the establishment of one or more new term loan Commitments (each, an “Incremental Term Loan

Commitment”) by an amount not in excess of $500,000,000 in the aggregate (for both of clauses (x) and (y)) and not less than $100,000,000 individually. Each such notice shall specify (i) the date (each, an “Increase Effective Date”) on which Borrower proposes that the increased or new Commitments shall be effective, which shall be a date not fewer than 10 Business Days after the date on which such notice is delivered to the Administrative Agent and (ii) the identity of each Assignee to whom Borrower proposes any portion of such increased or new Commitments be allocated and the amounts of such allocations; provided that any existing Lender approached to provide all or a portion of the increased or new Commitments may elect or decline, in its sole discretion, to provide such increased or new Commitment.

(b) The increased or new Commitments shall become effective, as of such Increase Effective Date; provided that:

(ii) no Default shall have occurred and be continuing or would result from the borrowings to be made on the Increase Effective Date;

(iii) after giving pro forma effect to the borrowings to be made on the Increase Effective Date and to any change in Consolidated EBITDA and any increase in Debt resulting from the consummation of any acquisition permitted by this Agreement concurrently with such borrowings as of the date of the most recent financial statements delivered pursuant to Section 6.1(b) or (c), the Borrower shall be in compliance with each of the covenants set forth in Section 7.16;

(iv) the Borrower shall make any payments required pursuant to Section 2.20 in connection with any adjustment of Revolving Loans pursuant to Section 2.24(d); and

(v) the Borrower shall deliver or cause to be delivered any legal opinions or other documents reasonably requested by the Administrative Agent in connection with any such transaction.

(i) terms and provisions of Loans made pursuant to Incremental Term Loan Commitments (“Incremental Term Loans”) shall be, except as otherwise set forth herein or in the Increase Joinder, identical to the Tranche B Term Loans (it being understood that Incremental Term Loans may be part of an existing tranche of Term Loans);

(ii) all terms and provisions (including maturity date) of Revolving Loans made pursuant to new Commitments shall be identical to the existing Revolving Loans;

(iii) the weighted average life to maturity of all new Term Loans shall be no shorter than the weighted average life to maturity of the existing Tranche B Term Loans;

(iv) the maturity date of Incremental Term Loans shall not be earlier than the Tranche B Term Loan Maturity Date; and

(v) the Applicable Margins for the new Term Loans shall be determined by Borrower and the applicable new Lenders; provided, however, that the Applicable Margins for the new Term Loans shall not be greater than the highest Applicable Margins that may, under any circumstances, be payable with respect to Tranche B Term Loans plus 50 basis points (and the Applicable Margins applicable to the Tranche B Term Loans shall be increased to the extent necessary to achieve the foregoing).

The increased or new Commitments shall be effected by a joinder agreement (the “Increase Joinder”) executed by Borrower, the Administrative Agent and each Lender making such increased or new Commitment, in form and substance satisfactory to each of them. The Increase Joinder may, without the consent of any other Lenders, effect such amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the opinion of the Administrative Agent, to effect the provisions of this Section 2.24.

(d) To the extent the Commitments being increased on the relevant Increase Effective Date are Revolving Commitments, then each of the Revolving Lenders having a Revolving Commitment prior to such Increase Effective Date (the “Pre-Increase Revolving Lenders”) shall assign to any Revolving Lender which is acquiring a new or additional Revolving Commitment on the Increase Effective Date (the “Post-Increase Revolving Lenders”), and such Post-Increase Revolving Lenders shall purchase from each Pre-Increase Revolving Lender, at the principal amount thereof, such interests in the Revolving Loans and participation interests in LC Obligations and Swingline Loans outstanding on such Increase Effective Date as shall be necessary in order that, after giving effect to all such assignments and purchases, such Revolving Loans and participation interests in LC Obligations and Swingline Loans will be held by Pre-Increase Revolving Lenders and Post-Increase Revolving Lenders ratably in accordance with their Revolving Commitments after giving effect to such increased Revolving Commitments.

(e) On any Increase Effective Date on which new Commitments for Term Loans are effective, subject to the satisfaction of the foregoing terms and conditions, each Lender of such new Commitment shall make a Term Loan to the Borrower in an amount equal to its new Commitment.

(f) The Loans and Commitments established pursuant to this paragraph shall constitute Loans and Commitments under, and shall be entitled to all the benefits afforded by, this Agreement and the other Loan Documents, and shall, without limiting the foregoing, benefit equally and ratably from Section 10 hereof and security interests created by the Security Documents. The Loan Parties shall take any actions reasonably required by the Administrative Agent to ensure and/or demonstrate that the Lien and security interests granted by the Security Documents continue to be perfected under the UCC or otherwise after giving effect to the establishment of any such class of Term Loans or any such new Commitments.

(a) Subject to the terms and conditions hereof, the Issuing Lender, in reliance on the agreements of the other Revolving Lenders set forth in Section 3.4, agrees to issue letters of credit (“Letters of Credit”) for the account of the Borrower on any Business Day during the Revolving Commitment Period in such form as may be approved from time to time by the Issuing Lender; provided that the Issuing Lender shall have no obligation to issue any Letter of Credit if, after giving effect to such issuance, (i) the LC Obligations would exceed the LC Commitment or (ii) the aggregate amount of the Available Revolving Commitments would be less than zero. Each Letter of Credit shall (i) be denominated in Dollars and (ii) expire no later than the earlier of (x) the first anniversary of its date of issuance and (y) the date that is fifteen Business Days prior to the Revolving Termination Date, provided that any Letter of Credit with a one-year term may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in clause (y) above).

(b) The Issuing Lender shall not at any time be obligated to issue any Letter of Credit if such issuance would conflict with, or cause the Issuing Lender or any Revolving Lender to exceed any limits imposed by, any applicable Requirement of Law. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any Application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Issuing Lender relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

(c) All Existing Letters of Credit shall be deemed to be issued hereunder and shall constitute Letters of Credit subject to the terms hereof.

3.2 Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the Issuing Lender) to the Issuing Lender and the Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a notice pursuant to an LC Request requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with Section 3.1(a)), the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by the Issuing Lender, the Borrower also shall submit an Application on the Issuing Lender’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension, (i) the LC Obligations shall not exceed $125,000,000 and (ii) the Available Revolving Commitments would not be less than zero.

3.3 Fees and Other Charges. The Borrower shall pay the fees specified in Section 2.8.

3.4 Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Lender or the Lenders, the Issuing Lender hereby grants to each Revolving Lender, and each Revolving Lender hereby acquires from the Issuing Lender, a participation in such Letter of Credit equal to such Lender’s Revolving Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Revolving Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Lender, such Lender’s Revolving Percentage of each LC Disbursement made by the Issuing Lender and not reimbursed by the Borrower on the date due as provided in Section 3.5, or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Revolving Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Revolving Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

3.5 Reimbursement. If the Issuing Lender shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 1:00 P.M., New York City time, on the

date that such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 12:00 noon, New York City time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 1:00 P.M., New York City time, on (i) the Business Day that the Borrower receives such notice, if such notice is received prior to 12:00 noon, New York City time, on the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that, if such LC Disbursement is not less than $1,000,000, the Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.5 or 2.6 that such payment be financed with an ABR Revolving Loan or Swingline Loan in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Revolving Loan or Swingline Loan. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Revolving Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Revolving Percentage thereof. Promptly following receipt of such notice, each Revolving Lender shall pay to the Administrative Agent its Revolving Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.5 (without regard to minimum amounts) and Section 2.17(e) with respect to Loans made by such Revolving Lender (and such Sections shall apply, mutatis mutandis, to the payment obligations of the Revolving Lenders), and the Administrative Agent shall promptly pay to the Issuing Lender the amounts so received by it from the Revolving Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this paragraph, the Administrative Agent shall distribute such payment to the Issuing Lender or, to the extent that Revolving Lenders have made payments pursuant to this paragraph to reimburse the Issuing Lender, then to such Revolving Lenders and the Issuing Lender as their interests may appear. Any payment made by a Revolving Lender pursuant to this paragraph to reimburse the Issuing Lender for any LC Disbursement (other than the funding of ABR Revolving Loans or a Swingline Loan as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

3.6 Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in Section 3.5 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 the Issuing Lender 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 set-off against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Lender, 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 the Issuing Lender; provided that the foregoing shall not be construed to excuse the Issuing Lender 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 the Issuing Lender’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 willful misconduct on the part of the Issuing

Lender (as finally determined by a court of competent jurisdiction), the Issuing Lender 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 Lender 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.

3.7 Disbursement Procedures. The Issuing Lender shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Lender shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Lender 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 the Issuing Lender and the Revolving Lenders with respect to any such LC Disbursement.

3.8 Interim Interest. If the Issuing Lender 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 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 Section 3.5, then Section 2.14(c) shall apply. Interest accrued pursuant to this Section shall be for the account of the Issuing Lender, except that interest accrued on and after the date of payment by any Revolving Lender pursuant to Section 3.5 to reimburse the Issuing Lender shall be for the account of such Revolving Lender to the extent of such payment.

3.9 Replacement of the Issuing Lender. The Issuing Lender may be replaced at any time with another party eligible to become the Issuing Lender as provided herein, by written notice given by the Borrower (with the approval of the successor Issuing Lender and the Administrative Agent) to the replaced Issuing Lender; provided that prior to such replacement all Letters of Credit issued by the replaced Issuing Lender are terminated or cash collateralized on terms satisfactory to the replaced Issuing Lender. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Lender. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Lender pursuant to Section 3.3). From and after the effective date of any such replacement, (i) the successor Issuing Lender shall have all the rights and obligations of the Issuing Lender under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Lender” shall be deemed to refer to such successor or to any previous Issuing Lender, or to such successor and all previous Issuing Lenders, as the context shall require. After the replacement of an Issuing Lender hereunder, the replaced Issuing Lender shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Lender 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.

3.10 Cash Collateralization. If 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 Obligations representing greater than 50% of the total LC Obligations) demanding the deposit of cash collateral pursuant to this Section, the Borrower shall deposit in an account with the Collateral Agent, in the name of the Collateral Agent and for the benefit of the Secured Parties, an amount in cash equal to 105% of the LC Obligations as of

such date plus any accrued and unpaid interest thereon; 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 Section 8.1(g). Such deposit shall be held by the Collateral Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement. The Collateral 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 Collateral Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Collateral Agent to reimburse the Issuing Lender 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 Obligations at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with LC Obligations representing greater than 50% of the total LC Obligations), be applied to satisfy other obligations of the Borrower under this Agreement, and any surplus remaining shall be returned to the Borrower after all Events of Default triggering such deposit cease to exist. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, 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.

Each Loan Party represents and warrants to the Administrative Agent, the Collateral Agent, the Issuing Lender and each of the Lenders (with references to the Group Members being references thereto after giving effect to the Transactions unless otherwise expressly stated) that:

4.1 Organization; Power. Each Loan Party and each of its Subsidiaries (i) is duly organized, validly existing and in good standing (if such concept is applicable) under the laws of the jurisdiction of its organization, (ii) is duly qualified and in good standing as a foreign business enterprise (if such concept is applicable) in each other jurisdiction in which it owns or leases property or in which the conduct of its business requires it to so qualify or be licensed except where the failure to be so qualified or licensed would not, individually or in the aggregate, result in a Material Adverse Effect and (iii) has all requisite power and authority (including, without limitation, all material Governmental Authorizations) to own or lease and operate its properties and to carry on its business as now conducted and as proposed to be conducted.

4.2 Capital Stock; Subsidiaries. Set forth on Schedule 1(a) to the Perfection Certificate is a complete and accurate list of all Subsidiaries of the Borrower, showing as of the date hereof (as to each Loan Party) the jurisdiction of its incorporation, the address of its principal place of business and its U.S. taxpayer identification number or, in the case of any non-U.S. Loan Party that does not have a U.S. taxpayer identification number, its unique identification number issued to it by the jurisdiction of its incorporation. The copy of the charter of each Loan Party and each amendment thereto provided pursuant to Section 5.1(b) is a true and correct copy of each such document, each of which is valid and in full force and effect. Schedule 10(a) to the Perfection Certificate shows the number of shares or other units of each class of each Subsidiary’s Capital Stock authorized, and the number outstanding, on the date hereof and the percentage of each such class of its Capital Stock owned (directly or indirectly) by the Borrower or any Subsidiary thereof and the number of shares or other units covered by all outstanding options, warrants, rights of conversion or purchase and similar rights at the date hereof, except for any obligations or

rights of the Borrower or any of its Subsidiaries to acquire any minority interest in any Subsidiary of the Borrower that is a partnership or a limited liability company. All of the outstanding Capital Stock of each such Subsidiary (A) (in the case of Subsidiaries that are corporations) has been validly issued, is fully paid and non-assessable and (B) to the extent owned by the Borrower or one or more of its Subsidiaries, is free and clear of all Liens, except those created under the Security Documents or Permitted Liens.

4.3 Authorization; No Conflicts. The execution, delivery and performance by each Loan Party of each Loan Document to which it is or is to be a party, and the consummation of the Transactions, are within such Loan Party’s corporate, partnership or limited liability company powers, as applicable, have been duly authorized by all necessary corporate, partnership or limited liability company action, as applicable, and do not (i) contravene such Loan Party’s Constitutive Documents, (ii) violate any Requirements of Law, (iii) conflict with or result in the breach of, or constitute a default or require any payment to be made under, any material contract, loan agreement, indenture, mortgage, deed of trust, lease or other instrument binding on or affecting any Loan Party or any of its properties or (iv) except for the Liens created under the Loan Documents, result in or require the creation or imposition of any Lien upon or with respect to any of the properties of any Loan Party. No Loan Party is in violation of any such Requirements of Law, the violation of which would be reasonably likely, individually or in the aggregate, to have a Material Adverse Effect.

4.4 No Approvals. No Governmental Authorization, and no other authorization or approval or other action by, and no notice to or filing with, any Governmental Authority or any other third party is required for (i) the due execution, delivery, recordation, filing or performance by any Loan Party of any Loan Document to which it is or is to be a party, or for the consummation of the Transactions, (ii) the grant by any Loan Party of the Liens granted by it pursuant to the Security Documents, (iii) the perfection or maintenance of the Liens created under the Security Documents on such of the Collateral located in the United States in which a Lien may be perfected by the filing of financing statements, the recordation of security agreements with the U.S. Patent and Trademark Office or the U.S. Copyright Office or the delivery of Collateral (including the first priority nature thereof) or (iv) the exercise by any Agent or any Lender of its rights under the Loan Documents or the remedies in respect of the Collateral pursuant to the Security Documents, except for (A) the authorizations, approvals, filings and actions described on Schedule 4.4 hereto, all of which either (i) have been duly obtained and are in full force and effect or will be obtained and in full force and effect prior to the Closing Date or (ii) the failure to obtain could not reasonably be expected to result in a Material Adverse Effect, (B) filings, notices, recordings and other similar actions necessary for the creation or perfection of the Liens and security interests contemplated by the Loan Documents and (C) the actions required by laws generally with respect to the exercise by secured creditors of their rights and remedies. Except as specified on Schedule 4.4 hereto applicable waiting periods in connection with the Transactions have expired without any action having been taken by any competent authority restraining, preventing or imposing materially adverse conditions upon the Transactions or the rights of the Loan Parties or their Subsidiaries freely to transfer or otherwise dispose of, or to create any Lien on, any properties now owned or hereafter acquired by any of them.

4.5 Enforceability. This Agreement has been, and each other Loan Document when delivered hereunder will have been, duly executed and delivered by each Loan Party thereto. This Agreement is, and each other Loan Document when delivered hereunder will be, the legal, valid and binding obligation of each Loan Party thereto, enforceable against such Loan Party in accordance with its terms.

4.6 Litigation. There is no action, suit, investigation, litigation or proceeding affecting any Loan Party or any of its Subsidiaries, including any Environmental Action, pending or, to the knowledge of the Loan Parties, threatened before any Governmental Authority or arbitrator that (i) would be reasonably likely, individually or in the aggregate, to have a Material Adverse Effect or (ii) purports to affect the legality, validity or enforceability of any Loan Document or the consummation of the Transactions, except as disclosed prior to the Closing Date in the Borrower’s filings made with the SEC.

(a) Historical Financial Statements. Borrower has heretofore delivered to the Lenders the Consolidated balance sheets and related statements of income, stockholders’ equity and cash flows of Borrower (i) as of and for the fiscal years ended December 31, 2004, December 31, 2003 and December 31, 2002, audited by and accompanied by the unqualified opinion of KPMG LLP, independent public accountants, and (ii) as of and for the three-month period ended March 31, 2005 and for the comparable period of the preceding fiscal year, in each case, certified by the chief financial officer of Borrower. Such financial statements and all financial statements delivered pursuant to Sections 6.1(b) and (c) have been prepared in accordance with GAAP and present fairly and accurately the financial condition and results of operations and cash flows of Borrower as of the dates and for the periods to which they relate except, in the case of interim financial statements, for the absence of footnotes and the same being subject to year end audit adjustments. Borrower has heretofore delivered to the Lenders the Consolidated balance sheets and related statements of income, stockholders’ equity and cash flows of the Acquired Business (i) as of and for the fiscal years ended December 31, 2004, December 31, 2003 and December 31, 2002, audited by and accompanied by the unqualified opinion of PricewaterhouseCoopers LLP, independent public accountants. Such financial statements have been prepared in accordance with GAAP and present fairly and accurately the financial condition and results of operations and cash flows of the Acquired Business as of the dates and for the periods to which they relate.

(b) No Liabilities. Except as set forth in the financial statements referred to in Section 4.7(a), there are no liabilities of any Group Member of any kind, whether accrued, contingent, absolute, determined, determinable or otherwise, which could reasonably be expected to result in a Material Adverse Effect, and there is no existing condition, situation or set of circumstances which could reasonably be expected to result in such a liability, other than liabilities under the Loan Documents, the Senior Note Documents and the Senior Subordinated Note Documents. Since December 31, 2004 there has been no event, change, circumstance or occurrence that, individually or in the aggregate, has had or could reasonably be expected to have a Material Adverse Effect (excluding the Borrower’s entering into the Loan Documents, the Senior Note Documents and the Senior Subordinated Note Documents), provided that the representation and warranty in this sentence shall only be effective after the initial Credit Extension.

(c) Pro Forma Financial Statements. Borrower has heretofore delivered to the Lenders Borrower’s unaudited pro forma condensed consolidated balance sheet and statement of income and pro forma EBITDA for the fiscal year ended December 31, 2004, after giving effect to the Transactions as if they had occurred on such date in the case of the balance sheet and as of the beginning of all periods presented in the case of the statement of income. Such pro forma financial statements have been prepared in good faith by the Loan Parties, based on the assumptions stated therein (which assumptions are believed by the Loan Parties on the date hereof and on the Closing Date to be reasonable), accurately reflect all adjustments required to be made to give effect to the Transactions, and in accordance with Regulation S-X, and present fairly in all material respects the pro forma consolidated financial position and results of operations of Borrower as of such date and for such periods, assuming that the Transactions had occurred at such dates.

(d) Forecasts. The forecasts of financial performance of Borrower and its subsidiaries furnished to the Lenders have been prepared in good faith by Borrower and based on assumptions believed by Borrower to reasonable.

(a) Generally. Each Group Member has good title to, or valid leasehold interests in, all its property material to its business, free and clear of all Liens except for Permitted Liens (or in the case of Collateral, Permitted Collateral Liens) and minor irregularities or deficiencies in title that, individually or in the aggregate, do not interfere with its ability to conduct its business as currently conducted or to utilize such property for its intended purpose. The property of the Group Members, taken as a whole, (i) is in good operating order, condition and repair (ordinary wear and tear excepted) and (ii) constitutes all the property which is required for the business and operations of the Group Members as presently conducted.

(b) Real Property. Schedule 4.8 contains a true and complete list of each interest in Real Property (i) owned by any Group Member as of the date hereof and describes the type of interest therein held by such Group Member and whether such owned Real Property is leased and (ii) leased, subleased or otherwise occupied or utilized by any Group Member, as lessee, sublessee, franchisee or licensee, as of the date hereof and describes the type of interest therein held by such Group Member.

(c) No Recovery Event. No Group Member has received any notice of, nor has any knowledge of, the occurrence or pendency or contemplation of any Recovery Event affecting all or any portion of its property. No Mortgage encumbers improved Real Property that is located in an area that has been identified by the Secretary of Housing and Urban Development as an area having special flood hazards within the meaning of the National Flood Insurance Act of 1968 unless flood insurance available under such Act has been obtained in accordance with Section 6.5(d).

(d) Collateral. Each Group Member owns or has rights to use all of the Collateral and all rights with respect to any of the foregoing used in, necessary for or material to each Group Member’s business as currently conducted. The use by each Group Member of such Collateral and all such rights with respect to the foregoing do not infringe on the rights of any person other than such infringement which could not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect. No claim has been made and remains outstanding that any Group Member’s use of any Collateral does or may violate the rights of any third party that could, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

(a) Ownership/No Claims. Each Loan Party owns, or is licensed to use, all Intellectual Property necessary for the conduct of its business as currently conducted, except for those the failure to own or license which, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. No claim has been asserted and is pending by any person challenging or questioning the use of any such Intellectual Property or the validity or effectiveness of any such Intellectual Property, nor does any Loan Party know of any valid basis for any such claim. The use of such Intellectual Property by each Loan Party does not infringe the rights of any person, except for such claims and infringements that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.

(b) Registrations. On and as of the date hereof (i) each Loan Party owns and possesses the right to use, and has done nothing to authorize or enable any other person to use, any copyright, patent or trademark (as such terms are defined in the Security Agreement) listed in Schedule 12(a) or 12(b) to the Perfection Certificate and (ii) all registrations listed in Schedule 12(a) or 12(b) to the Perfection Certificate are valid and in full force and effect.

(c) No Violations or Proceedings. To each Loan Party’s knowledge, on and as of the date hereof, there is no material violation by others of any right of such Loan Party with respect to any copyright, patent or trademark listed in Schedule 12(a) or 12(b) to the Perfection Certificate, pledged by it under the name of such Loan Party.

4.10 No Material Misstatements. Neither the Confidential Information Memorandum nor any other information, exhibit or report furnished by any Loan Party to any Agent or any Lender in connection with the negotiation and syndication of the Loan Documents or pursuant to the terms of the Loan Documents contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements made therein not misleading, except with respect to any projections or forecasts contained in such materials, the Group Members represent only that the same were prepared in good faith on the basis of assumptions believed to be reasonable.

4.11 Margin Stock. No Group Member is engaged in the business of extending credit for the purpose of purchasing or carrying Margin Stock, and no proceeds of any Loan or drawings under any Letter of Credit will be used to purchase or carry any Margin Stock or to extend credit to others for the purpose of purchasing or carrying any Margin Stock, except for purchases of the Borrower’s Capital Stock permitted by Section 7.7.

4.12 Investment Company Act; Public Utility Holding Company Act. Neither any Loan Party nor any of its Subsidiaries is an “investment company,” or an “affiliated person” of, or “promoter” or “principal underwriter” for, an “investment company,” as such terms are defined in the Investment Company Act of 1940, as amended. Neither any Loan Party nor any of its Subsidiaries is a “holding company,” or a “subsidiary company” of a “holding company,” or an “affiliate” of a “holding company” or of a “subsidiary company” of a “holding company,” as such terms are defined in the Public Utility Holding Company Act of 1935, as amended. Neither the making of any Loans, nor the issuance of any Letters of Credit, nor the application of the proceeds or repayment thereof by the Borrower, nor the consummation of the other transactions contemplated by the Loan Documents and Transaction Documents, will violate any provision of any such Act or any rule, regulation or order of the SEC thereunder.

4.13 Solvency. Each Loan Party is, individually and together with its Subsidiaries, Solvent (both before and after any applicable Credit Extension).

4.14 Employee Benefit Plans. (i) No ERISA Event has occurred or is reasonably expected to occur with respect to any Plan that has resulted in or is reasonably expected to result in a material liability of any Loan Party.

(ii) Schedule B (Actuarial Information) to the most recent annual report (Form 5500 Series) for each Plan, copies of which have been filed with the Internal Revenue Service and furnished to the Lenders, is complete and accurate and fairly presents the funding status of such Plan, and since the date of such Schedule B there has been no material adverse change in such funding status.

(iii) Neither any Loan Party nor any ERISA Affiliate has incurred or is reasonably expected to incur any Withdrawal Liability exceeding $100,000 to any Multiemployer Plan.

(iv) Neither any Loan Party nor any ERISA Affiliate has been notified by the sponsor of a Multiemployer Plan that such Multiemployer Plan is in reorganization or has been terminated, within the meaning of Title IV of ERISA, and no such Multiemployer Plan is reasonably expected to be in reorganization or to be terminated, within the meaning of Title IV of ERISA.

(v) Each Loan Party is in compliance in all material respects with the presently applicable provisions of ERISA and the Code with respect to each Plan.

(vi) The present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of all such underfunded Plans by an amount that could reasonably be expected to have a Material Adverse Effect.

(vii) The Loan Parties do not maintain or contribute to any plan, program, policy, arrangement or agreement with respect to employees (or former employees) employed outside the United States.

(i) The operations and properties of each Loan Party comply with all applicable Environmental Laws and Environmental Permits, except where any such failure to comply would not be reasonably expected to have a Material Adverse Effect; all past non-compliance with such Environmental Laws and Environmental Permits has been resolved without ongoing obligations or costs, except where any such failure to comply would not be reasonably expected, individually or in the aggregate, to have a Material Adverse Effect; no Environmental Action is pending or, to the Loan Parties’ knowledge threatened, against any Loan Party; and no circumstances exist that could be reasonably likely to (A) form the basis of an Environmental Action against any Loan Party or any of properties currently owned or operated by any of them that could, individually or in the aggregate, have a Material Adverse Effect or (B) cause any such property to be subject to any restrictions on ownership, occupancy, use or transferability under any Environmental Law.

(ii) None of the properties currently or, to Borrower’s knowledge formerly, owned or operated by any Loan Party is listed or proposed for listing on the NPL or on the CERCLIS or any analogous foreign, state or local list or, to the Loan Parties’ knowledge, is adjacent to any such property; and except to the extent that any of the following would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, (A) there are no and, to the Loan Parties’ knowledge, never have been any underground or aboveground storage tanks or related piping or any surface impoundments, land disposal areas, septic tanks, pits, sumps or lagoons in which Hazardous Materials are being or have been treated, stored or disposed on any property currently owned or operated by any Loan Party or, to their knowledge, on any property formerly owned or operated by any Loan Party, (B) there is no asbestos or asbestos-containing material on or at any facility or property currently owned or operated by any Loan Party, and (C) Hazardous Materials have not been released, discharged or disposed of on, at, under or from any property currently or, to Borrower’s knowledge formerly owned or operated by any Loan Party.

(iii) No Loan Party is undertaking, and has not completed, either individually or together with other potentially responsible parties, any investigation or assessment or remedial or response action relating to any actual or threatened release, discharge or disposal of Hazardous Materials at any location; and all Hazardous Materials generated, used, treated, handled or stored at, or transported to or from, any property currently or formerly owned or operated by any Loan Party have been disposed of in a manner that could not reasonably be expected to result in liability to any Loan Party that, individually or in the aggregate, would have a Material Adverse Effect.

4.16 Taxes. Each Loan Party and each of its Affiliates has duly filed, has caused to be duly filed or has been included in all tax returns (Federal, state, local and foreign) required to be filed and has

paid all Taxes whether or not shown to be due on a tax return, together with applicable interest and penalties. Each Loan Party and each of its Affiliates has made adequate provision in accordance with GAAP for all Taxes not yet due and payable. Each Loan Party and each of its Affiliates is unaware of any proposed or pending tax assessments, deficiencies or audits that could be reasonably expected to, individually or in the aggregate, result in a Material Adverse Effect. No Loan Party and or any of its Affiliates has ever been a party to any understanding or arrangement constituting a “tax shelter” within the meaning of Section 6662(d)(2)(C)(iii) of the Code or within the meaning of Section 6111(c) or Section 6111(d) of the Code as in effect immediately prior to the enactment of the American Jobs Creation of 2004, or has ever “participated” in a “reportable transaction” within the meaning of Treasury Regulation Section 1.6011-4, except as could not be reasonably expected to, individually or in the aggregate, result in a Material Adverse Effect.

4.17 Government Programs; Medicare/Medicaid/Tricare. (a) The dialysis facilities operated by each Group Member (the “Dialysis Facilities”) are qualified for participation in the Medicare programs and the Medicaid programs and Tricare programs in which they participate (together with their respective intermediaries or carriers, the “Government Reimbursement Programs”) and are entitled to reimbursement under the Medicare program for services rendered to qualified Medicare beneficiaries, and comply in all material respects with the conditions of participation in all Government Reimbursement Programs in which they participate or have participated, except for the fact that Dialysis Facilities (i) newly developed by Group Members may from time to time be awaiting an initial Medicare certification and/or initial Medicare or Medicaid provider number in accordance with normal business practice because of standard waiting times between the proper timely filing of the relevant documents therefor and the receipt of such certification and/or provider number and (ii) acquired by Group Members may from time to time be awaiting a Medicare or Medicaid provider number issued in the name of such Group Member in accordance with normal business practice because of standard waiting times between the proper timely filing of the relevant documents therefor and the receipt of such provider number.

6.10 Transactions with Affiliates. Conduct, and cause each of its Subsidiaries to conduct, all transactions otherwise permitted under the Loan Documents with any of their Affiliates on terms that are fair and reasonable and no less favorable to the Borrower or such Subsidiary than it would obtain in a comparable arm’s-length transaction with a Person not an Affiliate (it being understood that the Transactions are deemed to be on such terms).

6.11 Use of Proceeds. Use the proceeds of the Loans only for the purposes set forth in Section 4.20.

(a) Subject to this Section 6.12, with respect to any property acquired after the Closing Date by any Loan Party that is intended to be subject to the Lien created by any of the Security Documents but is not so subject, within 15 Business Days following the end of the Fiscal Quarter in which such acquisition occurs (i) execute and deliver to the Administrative Agent and the Collateral Agent such amendments or supplements to the relevant Security Documents or such other documents as the Administrative Agent or the Collateral Agent shall deem necessary or advisable to grant to the Collateral Agent, for its benefit and for the benefit of the other Secured Parties, a Lien on such property subject to no Liens other than Permitted Collateral Liens, and (ii) take all actions necessary to cause such Lien to be duly perfected to the extent required by such Security Document in accordance with all applicable Requirements of Law, including the filing of financing statements in such jurisdictions as may be reasonably requested by the Administrative Agent.

(b) With respect to any person that is or becomes a Subsidiary after the Closing Date, within 15 Business Days following the end of the Fiscal Quarter in which such person becomes a Subsidiary (i) deliver to the Collateral Agent the certificates, if any, representing all of the Capital Stock of such Subsidiary, together with undated stock powers or other appropriate instruments of transfer executed and delivered in blank by a duly authorized officer of the holder(s) of such Capital Stock, and all intercompany notes owing from such Subsidiary to any Loan Party together with instruments of transfer executed and delivered in blank by a duly authorized officer of such Loan Party and (ii) cause such new Subsidiary (A) to execute a Joinder Agreement or such comparable documentation to become a Guarantor and a joinder agreement to the applicable Security Agreement, substantially in the form annexed thereto or, in the case of a Foreign Subsidiary, execute a security agreement compatible with the laws of such Foreign Subsidiary’s jurisdiction in form and substance reasonably satisfactory to the Administrative Agent, (B) to execute a Business Associate Agreement and (C) to take all actions necessary or advisable in the opinion of the Administrative Agent or the Collateral Agent to cause the Lien created by the applicable Security Agreement to be duly perfected to the extent required by such agreement in accordance with all applicable Requirements of Law, including the filing of financing statements in such jurisdictions as may be reasonably requested by the Administrative Agent or the Collateral Agent; provided that any Subsidiary of the Borrower will not be required to become a Guarantor and will not be required to comply with this Section 6.12(b) if the Loan Parties would be in compliance with Section 7.12 notwithstanding

such Subsidiary’s failure (and the failure of any other Subsidiaries) to comply with this Section 6.12(b).

Such Mortgages shall be granted pursuant to documentation reasonably satisfactory in form and substance to the Administrative Agent and the Collateral Agent and shall constitute valid and enforceable perfected Liens subject only to Permitted Collateral Liens or other Liens acceptable to the Collateral Agent. The Mortgages or instruments related thereto shall be duly recorded or filed in such manner and in such places as are required by law to establish, perfect, preserve and protect the Liens in favor of the Collateral Agent required to be granted pursuant to the Mortgages and all taxes, fees and other charges payable in connection therewith shall be paid in full. Such Loan Party shall otherwise take such actions and execute and/or deliver to the Collateral Agent such documents as the Administrative Agent or the Collateral Agent shall require to confirm the validity, perfection and priority of the Lien of any existing Mortgage or new Mortgage against such after-acquired Real Property (including a title insurance policy, a Survey and local counsel opinion (each in form and substance reasonably satisfactory to the Administrative Agent and the Collateral Agent) in respect of such Mortgage).

6.13 Security Interests; Further Assurances. Promptly, upon the reasonable request of the Administrative Agent, the Collateral Agent or any Lender, at the Borrower’s expense, execute, acknowledge and deliver, or cause the execution, acknowledgment and delivery of, and thereafter register, file or record, or cause to be registered, filed or recorded, in an appropriate governmental office, any document or instrument supplemental to or confirmatory of the Security Documents or otherwise deemed by the Administrative Agent or the Collateral Agent reasonably necessary or desirable for the continued validity, perfection and priority of the Liens on the Collateral covered thereby subject to no other Liens except as permitted by the applicable Security Document, or obtain any consents or waivers as may be necessary or appropriate in connection therewith. Deliver or cause to be delivered to the Administrative Agent and the Collateral Agent from time to time such other documentation, consents, authorizations, approvals and orders in form and substance reasonably satisfactory to the Administrative Agent and the Collateral Agent as the Administrative Agent and the Collateral Agent shall reasonably deem necessary to perfect or maintain the Liens on the Collateral pursuant to the Security Documents.

Each Loan Party agrees to promptly provide the Collateral Agent with certified Constitutive Documents reflecting any of the changes described in the preceding sentence. Each Loan Party also agrees to promptly notify the Collateral Agent of any change in the location of any office in which it maintains books or records relating to Collateral owned by it or any office or facility at which Collateral is located (including the establishment of any such new office or facility), other than changes in location to a Mortgaged Property or a leased property subject to a Landlord Access Agreement.

(ii) shall have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that such Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents); provided that such Agent shall not be required to take any action that, in its judgment or the judgment of its counsel, may expose such Agent to liability or that is contrary to any Loan Document or applicable Requirements of Law; and

(iii) shall, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to Borrower or any of its Affiliates that is communicated to or obtained by the person serving as such Agent or any of its Affiliates in any capacity.

No Agent shall be liable for any action taken or not taken by it (x) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as such Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 11.1) or (y) in the absence of its own gross negligence or willful misconduct. No Agent shall be deemed to have knowledge of any Default unless and until notice describing such Default is given to such Agent by the Borrower, a Lender or the Issuing Lender.

No Agent shall 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 or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Section 5 or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to such Agent. Without limiting the generality of the foregoing, the use of the term “agent” in this Agreement with reference to the Administrative Agent or the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom and is intended to create or reflect only an administrative relationship between independent contracting parties.

9.4 Reliance by Agent. Each 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 (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper person.

Each Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or the Issuing Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender or the Issuing Lender unless the Administrative Agent shall have received notice to the contrary from such Lender or the Issuing Lender prior to the making of such Loan or the issuance of such Letter of Credit. Each 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.

9.5 Delegation of Duties. Each Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by such Agent. Each Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Section shall apply to any such sub-agent and to the Related Parties of each 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 Agent.

9.6 Resignation of Agent. Each Agent may at any time give notice of its resignation to the Lenders, the Issuing Lender and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring Agent may on behalf of the Lenders and the Issuing Lender, appoint a successor Agent meeting the qualifications set forth above, provided that if the Agent shall notify the Borrower and the Lenders that no qualifying person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Collateral Agent on behalf of the Lenders or the Issuing Lender under any of the Loan Documents, the retiring Collateral Agent shall continue to hold such collateral security as nominee until such time as a successor Collateral Agent is appointed) and (2) all payments, communications and determinations provided to be made by, to or through an Agent shall instead be made by or to each Lender and the Issuing Lender directly, until such time as the Required Lenders appoint a successor Agent as provided for above in this paragraph. Upon the acceptance of a successor’s appointment as Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Agent, and the retiring Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this paragraph). The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Section 9 and Section 11.5 shall continue in effect for the benefit of such retiring 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 the retiring Agent was acting as Agent.

9.7 Non-Reliance on Agent and Other Lenders. Each Lender and the Issuing Lender acknowledges that it has, independently and without reliance upon any 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 and the Issuing Lender also acknowledges that it will,

independently and without reliance upon any 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 other Loan Document or any related agreement or any document furnished hereunder or thereunder.

9.8 No Other Duties, etc. Anything herein to the contrary notwithstanding, none of the bookmanagers, arrangers, Syndication Agent or Documentation Agents listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent, the Collateral Agent, a Lender or the Issuing Lender hereunder.

10.1 The Guarantee. The Guarantors hereby jointly and severally guarantee, as a primary obligor and not as a surety to each Secured Party and their respective successors and assigns, the prompt payment in full when due (whether at stated maturity, by required prepayment, declaration, demand, by acceleration or otherwise) of the principal of and interest (including any interest, fees, costs or charges that would accrue but for the provisions of the Title 11 of the United States Code after any bankruptcy or insolvency petition under Title 11 of the United States Code) on the Loans made by the Lenders to, and the Notes held by each Lender of, Borrower, and all other Secured Obligations from time to time owing to the Secured Parties by any Loan Party under any Loan Document, Specified Swap Agreement or Operating Indebtedness Agreement, in each case strictly in accordance with the terms thereof (such obligations being herein collectively called the “Guaranteed Obligations”). The Guarantors hereby jointly and severally agree that if Borrower or other Guarantor(s) shall fail to pay in full when due (whether at stated maturity, by acceleration or otherwise) any of the Guaranteed Obligations, the Guarantors will promptly pay the same in cash, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Guaranteed Obligations, the same will be promptly paid in full when due (whether at extended maturity, by acceleration or otherwise) in accordance with the terms of such extension or renewal.

10.2 Obligations Unconditional. The obligations of the Guarantors under Section 10.1 shall constitute a guaranty of payment and to the fullest extent permitted by applicable Requirements of Law, are absolute, irrevocable and unconditional, joint and several, irrespective of the value, genuineness, validity, regularity or enforceability of the Guaranteed Obligations of Borrower under this Agreement, the Notes, if any, or any other agreement or instrument referred to herein or therein, or any substitution, release or exchange of any other guarantee of or security for any of the Guaranteed Obligations, and irrespective of any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor (except for payment in full). Without limiting the generality of the foregoing, it is agreed that the occurrence of any one or more of the following shall not alter or impair the liability of the Guarantors hereunder, which shall remain absolute, irrevocable and unconditional under any and all circumstances as described above:

(i) at any time or from time to time, without notice to the Guarantors, the time for any performance of or compliance with any of the Guaranteed Obligations shall be extended, or such performance or compliance shall be waived;

(ii) any of the acts mentioned in any of the provisions of this Agreement or the Notes, if any, or any other agreement or instrument referred to herein or therein shall be done or omitted;

(iii) the maturity of any of the Guaranteed Obligations shall be accelerated, or any of the Guaranteed Obligations shall be amended in any respect, or any right under the Loan Documents or any other agreement or instrument referred to herein or therein shall be amended or waived in any respect or any other guarantee of any of the Guaranteed Obligations or any security therefor shall be released or exchanged in whole or in part or otherwise dealt with;

(iv) any Lien or security interest granted to, or in favor of, the Issuing Lender or any Lender or Agent as security for any of the Guaranteed Obligations shall fail to be perfected; or

The Guarantors hereby expressly waive diligence, presentment, demand of payment, protest and all notices whatsoever, and any requirement that any Secured Party exhaust any right, power or remedy or proceed against Borrower under this Agreement or the Notes, if any, or any other agreement or instrument referred to herein or therein, or against any other person under any other guarantee of, or security for, any of the Guaranteed Obligations. The Guarantors waive any and all notice of the creation, renewal, extension, waiver, termination or accrual of any of the Guaranteed Obligations and notice of or proof of reliance by any Secured Party upon this Guarantee or acceptance of this Guarantee, and the Guaranteed Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred in reliance upon this Guarantee, and all dealings between Borrower and the Secured Parties shall likewise be conclusively presumed to have been had or consummated in reliance upon this Guarantee. This Guarantee shall be construed as a continuing, absolute, irrevocable and unconditional guarantee of payment without regard to any right of offset with respect to the Guaranteed Obligations at any time or from time to time held by Secured Parties, and the obligations and liabilities of the Guarantors hereunder shall not be conditioned or contingent upon the pursuit by the Secured Parties or any other person at any time of any right or remedy against Borrower or against any other person which may be or become liable in respect of all or any part of the Guaranteed Obligations or against any collateral security or guarantee therefor or right of offset with respect thereto. This Guarantee shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon the Guarantors and the successors and assigns thereof, and shall inure to the benefit of the Lenders, and their respective successors and assigns, notwithstanding that from time to time during the term of this Agreement there may be no Guaranteed Obligations outstanding.

10.3 Reinstatement. The obligations of the Guarantors under this Section 10 shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of Borrower or other Loan Party in respect of the Guaranteed Obligations is rescinded or must be otherwise restored by any holder of any of the Guaranteed Obligations, whether as a result of any proceedings in bankruptcy or reorganization or otherwise.

10.4 Subrogation; Subordination. Each Guarantor hereby agrees that until the indefeasible payment and satisfaction in full in cash of all Guaranteed Obligations and the expiration and termination of the Commitments of the Lenders under this Agreement it shall not assert or exercise any right or remedy, direct or indirect, arising by reason of any performance by it of its guarantee in Section 10.1, whether by subrogation or otherwise, against Borrower or any other Guarantor of any of the Guaranteed Obligations or any security for any of the Guaranteed Obligations. Any Debt of any Loan Party permitted pursuant to Section 7.2(d) shall be subordinated to such Loan Party’s Secured Obligations in the manner set forth in the Intercompany Note evidencing such Debt.

10.5 Remedies. The Guarantors jointly and severally agree that, as between the Guarantors and the Lenders, the obligations of Borrower under this Agreement and the Notes, if any, may be declared to be forthwith due and payable as provided in Section 8.1 (and shall be deemed to have become automatically

due and payable in the circumstances provided in Section 8.1) for purposes of Section 10.1, notwithstanding any stay, injunction or other prohibition preventing such declaration (or such obligations from becoming automatically due and payable) as against Borrower and that, in the event of such declaration (or such obligations being deemed to have become automatically due and payable), such obligations (whether or not due and payable by Borrower) shall forthwith become due and payable by the Guarantors for purposes of Section 10.1.

10.6 Instrument for the Payment of Money. Each Guarantor hereby acknowledges that the guarantee in this Section 10 constitutes an instrument for the payment of money, and consents and agrees that any Lender or Agent, at its sole option, in the event of a dispute by such Guarantor in the payment of any moneys due hereunder, shall have the right to bring a motion-action under New York CPLR Section 3213.

10.7 Continuing Guarantee. Subject to Section 11.14, the guarantee in this Section 10 is a continuing guarantee of payment, and shall apply to all Guaranteed Obligations whenever arising.

10.8 General Limitation on Guaranteed Obligations. If in any action or proceeding involving any state corporate limited partnership or limited liability company law, or any applicable state, federal or foreign bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer law or regulation, or other law affecting the rights of creditors generally, the obligations of any Guarantor under Section 10.1 would otherwise be held or determined to be void, voidable, invalid or unenforceable, or subordinated to the claims of any other creditors, on account of the amount of its liability under Section 10.1, then, notwithstanding any other provision to the contrary, the amount of such liability shall, without any further action by such Guarantor, any Loan Party or any other person, be automatically limited and reduced to the highest amount that is valid and enforceable and not subordinated to the claims of other creditors.

10.9 Release of Guarantors. If, in compliance with the terms and provisions of the Loan Documents, all or substantially all of the Capital Stock or property of any Guarantor are sold or otherwise transferred (a “Transferred Guarantor”) to a person or persons, none of which is Borrower or a Subsidiary, such Transferred Guarantor shall, upon the consummation of such sale or transfer, be released from its obligations under this Agreement (including under Section 11.5 hereof) and its obligations to pledge and grant any Collateral owned by it pursuant to any Security Document and, in the case of a sale of all or substantially all of the Capital Stock of the Transferred Guarantor, the pledge of such Capital Stock to the Collateral Agent pursuant to the Security Agreement shall be released, and the Collateral Agent shall take such actions as are necessary to effect each such release in accordance with the relevant provisions of the Security Documents. If, in compliance with the terms and provisions of the Loan Documents (including, without limitation, Sections 7.5 and 7.13), Capital Stock of a Guarantor is sold or otherwise transferred so that such Guarantor is no longer a Wholly Owned Subsidiary of the Borrower, upon the consummation of such sale or transfer, such Guarantor shall be released, subject to pro forma compliance with Section 7.12, from its obligations under this Agreement (including under Section 10 and Section 11.5 hereof) and its obligations to pledge and grant any Collateral owned by it pursuant to any Security Document, and the Collateral Agent shall take such actions as are necessary to effect each such release in accordance with the relevant provisions of the Security Documents and to acknowledge in writing such release and the termination of the guarantee of such Guarantor if requested.

11.1 Amendments and Waivers. Neither this Agreement, any other Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions

of this Section 11.1. Amendments prior to the completion of the syndication of the Commitments (as determined by the Administrative Agent) shall, in addition to the other consents required by this Section 11.1, require the consent of the Administrative Agent. Subject to the preceding sentence, the Required Lenders and each Loan Party to the relevant Loan Document may, or, with the written consent of the Required Lenders, the Administrative Agent or the Collateral Agent, as applicable, and each Loan Party to the relevant Loan Document may, from time to time, (a) enter into written amendments, supplements or modifications hereto and to the other Loan Documents for the purpose of adding any provisions to this Agreement or the other Loan Documents or changing in any manner the rights of the Lenders or of the Loan Parties hereunder or thereunder or (b) waive, on such terms and conditions as the Required Lenders or the Administrative Agent or Collateral Agent, as the case may be, may specify in such instrument, any of the requirements of this Agreement or the other Loan Documents or any Default or Event of Default and its consequences; provided, however, that no such waiver and no such amendment, supplement or modification shall (i) forgive the principal amount or extend the final scheduled date of maturity of any Loan, extend the scheduled date of any amortization payment in respect of any Term Loan, reduce the stated rate of any interest, premium or fee payable hereunder (except (x) in connection with the waiver of applicability of any post-default increase in interest rates and (y) that any amendment or modification of defined terms used in the financial covenants in this Agreement shall not constitute a reduction in the rate of interest or fees for purposes of this clause (i)) or extend the scheduled date of any payment thereof, or increase the amount or extend the expiration date of any Lender’s Revolving Commitment or increase the maximum duration of Interest Periods hereunder or alter the provisions of Section 8.2 (it being understood that if additional classes of Term Loans or additional Loans under this Agreement consented to by the Required Lenders or additional Loans pursuant to Section 2.24 are made, such new Loans being included on a pro rata basis within Section 8.2 shall not be considered an alteration thereof), in each case without the written consent of each Lender directly affected thereby; (ii) eliminate or reduce the voting rights of any Lender under this Section 11.1 without the written consent of such Lender; (iii) reduce any percentage specified in the definition of “Required Lenders,” consent to the assignment or transfer by the Borrower of any of its rights and obligations under this Agreement and the other Loan Documents, release all or substantially all of the Collateral or release all or substantially all of the Guarantors from their guarantee under Section 10, in each case without the written consent of all Lenders (it being understood that lenders added pursuant to Section 2.24 or lenders under additional classes of Term Loans or additional Loans under this Agreement consented to by the Required Lenders being included in such definition shall not be deemed to require the written consent of all Lenders); (iv) amend, modify or waive any provision of Section 2.17 without the written consent of the Majority Facility Lenders in respect of each Facility adversely affected thereby; (v) reduce the amount of Net Cash Proceeds or Excess Cash Flow required to be applied to prepay Loans under this Agreement without the written consent of the Majority Facility Lenders with respect to each Facility; (vi) reduce the percentage specified in the definition of Majority Facility Lenders with respect to any Facility without the written consent of all Lenders under such Facility; (vii) change the application of prepayments as among or between Facilities under Section 2.11(d), without the written consent of the Majority Facility Lenders of each Facility that is being allocated a lesser prepayment as a result thereof (it being understood that if additional classes of Term Loans or additional Loans under this Agreement consented to by the Required Lenders or additional Loans pursuant to Section 2.24 are made, such new Loans may be included on a pro rata basis in the various prepayments required pursuant to Section 2.11(d)); (viii) expressly change or waive any condition precedent in Section 5.2 to any Revolving Borrowing without the written consent of the Majority Facility Lenders with respect to the Revolving Facility; (ix) amend, modify or waive any provision of Section 9 without the written consent of the Administrative Agent; (x) amend, modify or waive any provision of Section 2.6 or 2.7 without the written consent of the Swingline Lender; or (xi) amend, modify or waive any provision of Section 3 without the written consent of the Issuing Lender. Any such waiver and any such amendment, supplement or modification shall apply equally to each of the Lenders and shall be binding upon the Loan Parties, the Lenders, the Administrative Agent and all future holders of the Loans. In the case of

any waiver, the Loan Parties, the Lenders and the Administrative Agent shall be restored to their former position and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon.

Without the consent of any other person, the applicable Loan Party or Parties and the Administrative Agent and/or Collateral Agent may (in its or their respective sole discretion, or shall, to the extent required by any Loan Document) enter into any amendment or waiver of any Loan Document, or enter into any new agreement or instrument, to effect the granting, perfection, protection, expansion or enhancement of any security interest in any Collateral or additional property to become Collateral for the benefit of the Secured Parties, or as required by local law to give effect to, or protect, any security interest for the benefit of the Secured Parties, in any property or so that the security interests therein comply with applicable Requirements of Law.

If, in connection with any proposed change, waiver, discharge or termination of the provisions of this Agreement as contemplated by this Section, the consent of 75% of the Lenders whose consent is required is obtained but the consent of one or more of such other Lenders whose consent is required is not obtained, then the Borrower shall have the right to replace all, but not less than all, of such non-consenting Lender or Lenders (so long as all non-consenting Lenders are so replaced) with one or more persons pursuant to Section 2.22 so long as at the time of such replacement each such new Lender consents to the proposed change, waiver, discharge or termination.

(c) Electronic Communications. Notices and other communications to the Lenders and the Issuing Lender hereunder may (subject to Section 11.2(d)) be delivered or furnished by electronic communication (including e-mail and Internet or intranet websites) pursuant to procedures approved by the Administrative Agent; provided that the foregoing shall not apply to notices to any Lender or the Issuing Lender pursuant to Section 2 if such Lender or the Issuing Lender, as applicable, has notified the Administrative Agent that it is incapable of receiving notices under such Section by electronic communication. The Administrative Agent, the Collateral 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 (including as set forth in Section 11.2(d)); provided that approval of such procedures may be limited to particular notices or communications.

In addition, each Loan Party agrees to continue to provide the Communications to the Administrative Agent in the manner specified in this Agreement or any other Loan Document or in such other form, including hard copy delivery thereof, as the Administrative Agent shall require. Nothing in this Section 11.2 shall prejudice the right of the Agents, any Lender or any Loan Party to give any notice or other communication pursuant to this Agreement or any other Loan Document in any other manner specified in this Agreement or any other Loan Document or as any such Agent shall require.

To the extent consented to by the Administrative Agent in writing from time to time, Administrative Agent agrees that receipt of the Communications by the Administrative Agent at its e-mail address(es) set forth above shall constitute effective delivery of the Communications to the Administrative

Agent for purposes of the Loan Documents; provided that the Borrower shall also deliver to the Administrative Agent an executed original of each Compliance Certificate required to be delivered hereunder.

Each Loan Party further agrees that Administrative Agent may make the Communications available to the Lenders by posting the Communications on Intralinks or a substantially similar electronic transmission system (the “Platform”). The Platform is provided “as is” and “as available.” The Agents do not warrant the accuracy or completeness of the Communications, or the adequacy of the Platform and expressly disclaim liability for errors or omissions in the communications. No warranty of any kind, express, implied or statutory, including, without limitation, any warranty of merchantability, fitness for a particular purpose, non-infringement of third party rights or freedom from viruses or other code defects, is made by any Agent in connection with the Communications or the Platform. In no event shall the Administrative Agent or any of its Related Parties have any liability to the Loan Parties, any Lender or any other person for damages of any kind, including direct or indirect, special, incidental or consequential damages, losses or expenses (whether in tort, contract or otherwise) arising out of any Loan Party’s or the Administrative Agent’s transmission of communications through the Internet, except to the extent the liability of such person is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from such person’s gross negligence or willful misconduct.

11.3 No Waiver; Cumulative Remedies. No failure to exercise and no delay in exercising, on the part of the Administrative Agent or any Lender, any right, remedy, power or privilege hereunder or under the other Loan Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

11.4 Survival. All covenants, agreements, representations and warranties made by the Loan Parties 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, the Collateral Agent, the Issuing Lender 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 Sections 2.18, 2.19, 2.20 and 11.5 and Section 9 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.

(a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent, the Collateral Agent and their respective Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent and the Collateral Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of this Agreement, the Loan Documents or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated),

(ii) all reasonable out-of-pocket expenses incurred by the Issuing Lender in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iii) all reasonable out-of-pocket expenses incurred by the Administrative Agent, the Collateral Agent, the Issuing Lender or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, the Collateral Agent, the Issuing Lender 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; provided that the Borrower shall not be obligated to pay legal fees and expenses incurred pursuant to clauses (i) and (ii) above in connection with the syndication of the credit facilities or the preparation of the Loan Documents prior to the initial Credit Extension.

(b) The Borrower shall indemnify the Administrative Agent (or any sub-agent thereof), the Collateral Agent (or any sub-agent thereof), the Issuing Lender 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 Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder or the consummation of the Transactions or any other transactions contemplated hereby or thereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by the Issuing Lender to honor a demand for payment under a Letter of Credit 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 or threatened release of Hazardous Materials at, on, under or from any property owned or operated by any Group Member, any Environmental Liability related in any way to any Group Member or any violation of healthcare laws related in any way to any Group Member, 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, regardless of whether brought by a third party or by a Loan Party 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 been incurred primarily by reason of the gross negligence or willful misconduct of such Indemnitee and that if any Indemnitee shall receive indemnification that is later disallowed by this proviso, it shall promptly repay to the Borrower any such funds.

(c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent (or any sub-agent thereof), the Collateral Agent (or any sub-agent thereof), the Issuing Lender or the Swingline Lender under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent, the Collateral Agent, the Issuing Lender or the Swingline Lender, as the case may be, such Lender’s Aggregate Exposure 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, the Collateral Agent, the Issuing Lender 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, any Loan Document or any agreement or instrument contemplated hereby or thereby, 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 promptly after written demand therefor.

(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 the Issuing Lender 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 the Issuing Lender 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 Lender 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 (each, an “Assignee”) all or a portion of its rights and obligations under this Agreement (including all or a portion of Commitments and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld or delayed) of:

(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 under Section 8.1(a), 8.1(b) or 8.1(g) has occurred and is continuing, any other Person;

(B) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment to a Lender, an affiliate of a Lender or an Approved Fund; and

(C) the Issuing Lender and the Swingline Lender, provided that no consent of the Issuing Lender or the Swingline Lender shall be required for an assignment of all or any portion of a Term Loan or for an assignment to a Lender, an affiliate of a Lender or an Approved Fund.

(A) except in the case of an assignment to a Lender, an affiliate of a Lender or an Approved Fund or an assignment of the entire remaining amount of the assigning Lender’s Commitments or Loans under any Facility, the amount of the Commitments 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 (or, in the case of the Tranche B Term Facility, $1,000,000) unless each of the Borrower and the Administrative Agent otherwise consents, provided that (1) no such consent of the Borrower shall be required if an Event of Default under Sections 8.1(a), (b) or (g) has occurred and is continuing and (2) such amounts shall be aggregated in respect of each Lender and its affiliates or Approved Funds, if any;

(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 Facility;

(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 11.6, 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) below, from and after the effective date specified in each Assignment and Assumption the Assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all 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 Sections 2.18, 2.19, 2.20 and 11.5). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 11.6 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 Commitments 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 Lender and the Lenders shall 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 Agents, the Borrower, the Issuing Lender 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 2.7(b) or (c), 3.4, 3.5, 2.17(e) or 11.5, 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, the Issuing Lender 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 Commitments and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent, the Issuing Lender and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that (1) requires the consent of each Lender directly affected thereby pursuant to the proviso to the second sentence of Section 11.1 and (2) directly affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.18, 2.19 and 2.20, and shall be subject to Section 2.21, to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.7(b) as though it were a Lender, provided such Participant shall be subject to Section 11.7(a) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.18 or 2.19 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, which shall not be unreasonably withheld or delayed. Any Participant that is a Non-U.S. Lender shall not be entitled to the benefits of Section 2.19 unless such Participant agrees to comply with Section 2.19(e).

(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 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.

(e) Notwithstanding the foregoing, any Conduit Lender may assign any or all of the Loans it may have funded hereunder to its designating Lender without the consent of the Borrower or the Administrative Agent and without regard to the limitations set forth in Section 11.6(b). Each of the Borrower, each Lender and the Administrative Agent hereby confirms that it will not institute against a Conduit Lender or join any other Person in instituting against a Conduit Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding under any state bankruptcy or similar law, for one year and one day after the payment in full of the latest maturing commercial paper note issued by such Conduit Lender; provided, however, that each Lender designating any Conduit Lender hereby agrees to indemnify, save and hold harmless each other party hereto for any loss, cost, damage or expense arising out of its inability to institute such a proceeding against such Conduit Lender during such period of forbearance.

(f) The Borrower, at its sole expense and upon receipt of written notice from the relevant Lender, agrees to issue Note(s) to any Lender requiring Note(s) to facilitate transactions of the type described in this Section 11.6.

(a) Except to the extent that this Agreement expressly provides for payments to be allocated to a particular Lender or to the Lenders under a particular Facility, if any Lender (a “Benefitted Lender”) shall receive any payment of all or part of the Obligations owing to it, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 8.1(g), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of the Obligations owing to such other Lender, such Benefitted Lender shall purchase for cash from the other Lenders a participating interest in such portion of the Obligations owing to each such other Lender, or shall provide such other Lenders with the benefits of any such collateral, as shall be necessary to cause such Benefitted Lender to share the excess payment or benefits of such collateral ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such Benefitted Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest.

(b) 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 against any of and all the obligations of the Borrower 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.

11.8 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which 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 5.1, 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 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.

11.9 Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

11.10 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.

11.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

11.12 Submission to Jurisdiction; Waivers. Each Loan Party hereby irrevocably and unconditionally:

(a) submits for itself and its property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts of the State of New York, the courts of the United States for the Southern District of New York, and appellate courts from any thereof;

(b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same and 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;

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to it at its address set forth in Section 11.2 or at such other address of which the Administrative Agent shall have been notified pursuant thereto;

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and

(e) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section any special, exemplary, punitive or consequential damages.

(a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents;

(b) neither the Administrative Agent or the Collateral Agent nor any Lender has any fiduciary relationship with or duty to any Loan Party arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between the Administrative Agent, the Collateral Agent and Lenders, on one hand, and the Loan Parties, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

(c) no joint venture is created hereby or by the other Loan Documents or otherwise exists by virtue of the transactions contemplated hereby among the Lenders or among the Loan Parties and the Lenders.

(a) Notwithstanding anything to the contrary contained herein or in any other Loan Document, the Collateral Agent is hereby irrevocably authorized by each Lender (without requirement of notice to or consent of any Lender except as expressly required by Section 11.1) to take any action requested by the Borrower having the effect of releasing any Collateral or any Guarantor (i) to permit the consummation of any transaction involving such Collateral or Guarantor not prohibited by any Loan Document or that has been consented to in accordance with Section 11.1 or (ii) under the circumstances described in paragraph (b) below.

(b) At such time as the Loans, the LC Disbursements and the other accrued obligations (including accrued indemnity obligations) under the Loan Documents (other than obligations under or in respect of Swap Agreements) shall have been paid in full, the Commitments have been terminated and no Letters of Credit shall be outstanding, the Collateral shall be released from the Liens created by the Security Documents, and the Security Documents and all obligations (other than those expressly stated to survive such termination) of the Collateral Agent and each Loan Party under the Security Documents shall terminate, all without delivery of any instrument or performance of any act by any Person.

11.15 Confidentiality. Each of the Administrative Agent, the Collateral Agent, the Issuing Lender 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, (ii) any pledgee or prospective pledgee referred to in Section 11.6(d) or (iii) 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, the Collateral Agent, the Issuing Lender 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 Borrower relating to the Borrower or its business, other than any such information that is available to the Administrative Agent, the Collateral Agent, the Issuing Lender 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.

L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”) hereby notifies the Borrower that pursuant to the requirements of the Patriot 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 Patriot Act.

11.18 Interest Rate Limitation.
