Immediately prior to or substantially concurrently with the consummation of the Merger, (a) the Permitted Investors will contribute cash to Holdings (the “Equity Contributions”) in an aggregate amount that together with the value of the equity of Holdings held by members of management (the “Rollover Equity”) will be equal to at least 25% of the consolidated capitalization of Holdings and its subsidiaries after giving effect to the Transactions, and Holdings will contribute to the Borrower the portion of such cash contributions not used to pay Transaction Costs; (b) the Borrower will cause the repayment of, and terminate all commitments under and all liens in connection with, the Existing Credit Facility (the “Repayment”); and (c) the Borrower will enter into the Bridge Loan Credit Agreement.

The Borrower has requested that the Lenders extend credit in the form of (a) Tranche A Term Loans on the Effective Date in an aggregate principal amount not to exceed $125,000,000, (b) Tranche B Term Loans on the Effective Date in an aggregate principal amount not to exceed $125,000,000 and (c) Revolving Loans, Swingline Loans and Letters of Credit at any time and from time to time during the Revolving Availability Period, in an aggregate principal amount at any time outstanding not to exceed $100,000,000.

The proceeds of the Term Loans and any Revolving Loans borrowed on the Effective Date will be used by the Borrower on the Effective Date, solely (i) first, to pay the Transaction Costs, (ii) second, to pay all principal, interest, fees and other amounts outstanding under the Existing Credit Facility and (iii) third, together with the Equity Contributions, to pay the merger consideration (the “Merger Consideration”) required by the Merger Agreement; provided that no more than $5,000,000 in Revolving Loans may be drawn on the Effective Date. The proceeds of Revolving Loans borrowed after the Effective Date, Swingline Loans and Letters of Credit will be used by the Borrower for working capital and general corporate purposes (including Permitted Acquisitions).

Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Revolving Loans.

SECTION 2.02. Loans and Borrowings.

(a) Each Loan (other than a Swingline Loan) shall be made as part of a Borrowing consisting of Loans of the same Class and Type made by the Lenders ratably in accordance with their respective Commitments of the applicable Class. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder, provided that the Commitments of the Lenders are several and no Lender shall be responsible for any other Lender’s failure to make Loans as required.

(b) Subject to Section 2.14, each Revolving Borrowing and Term Loan Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may request in accordance herewith. Each Swingline Loan shall be an ABR Loan. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan, provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement.

(c) At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $500,000 and not less than $1,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $500,000 and not less than $1,000,000; provided that, notwithstanding

33 the foregoing each Swingline Loan shall be not less than $250,000 and if greater than such amount shall be in an amount that is an integral multiple of $100,000. Borrowings of more than one Type and Class may be outstanding at the same time. There shall not at any time be more than a total of ten Eurodollar Borrowings outstanding. Notwithstanding anything to the contrary herein, an ABR Revolving Borrowing or Swingline Loan may be in an aggregate amount, subject in the case of Swingline Loans to the limitations on the amounts thereof set forth in Section 2.04(a), (i) that is equal to the entire unused balance of the aggregate Revolving Commitments or (ii) that is required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.05(e).

(d) Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Revolving Maturity Date, the Tranche A Maturity Date or the Tranche B Maturity Date, as applicable.

SECTION 2.03. Requests for Borrowings. To request a Revolving Borrowing or Term Loan Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 1:00 p.m., New York City time, three Business Days before the date of the proposed Borrowing or (b) in the case of an ABR Borrowing, not later than 10 a.m., New York City time, one Business Day before the date of the proposed Borrowing. Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request signed by the Borrower. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02:

(i) whether the requested Borrowing is to be a Revolving Borrowing, a Tranche A Term Loan Borrowing or a Tranche B Term Loan Borrowing;

(vi) the location and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.06.

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Promptly following receipt of a Borrowing Request in accordance with this Section 2.03, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing.

SECTION 2.04. Swingline Loans.

(a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make Swingline Loans to the Borrower from time to time during the Revolving Availability Period, in

an aggregate principal amount at any time outstanding that will not result in (i) the aggregate principal amount of outstanding Swingline Loans exceeding $10,000,000 or (ii) the aggregate Revolving Exposures exceeding the aggregate Revolving Commitments, provided that the Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Swingline Loans.

(b) To request a Swingline Loan, the Borrower shall notify the Administrative Agent of such request by telephone (confirmed by telecopy), not later than 1:00 p.m., New York City time, on the day 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 maintained 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 2.05(e), by remittance to the Issuing Bank) by 3:00 p.m., New York City time, on the requested date of such Swingline Loan.

(c) The Swingline Lender may by written notice given to the Administrative Agent not later than 2:00 p.m., New York City time, on any Business Day require the Revolving Lenders to acquire participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which Revolving Lenders will participate. Promptly upon receipt of such notice, the Administrative Agent will give notice thereof to each Revolving Lender, specifying in such notice such Lender’s Applicable Percentage of such Swingline Loan or Swingline Loans. Each Revolving Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to the Administrative Agent, for the account of the Swingline Lender, such Lender’s Applicable Percentage of such Swingline Loan or Swingline Loans. Each Revolving Lender acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Revolving Lender shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.06 with respect to Loans made by such Lender (and Section 2.06 shall apply, mutatis mutandis, to the payment obligations of the Revolving Lenders), and the Administrative Agent shall promptly pay to the Swingline Lender the amounts so received by it from the Revolving Lenders. The Administrative Agent shall notify the Borrower of any participations in any Swingline Loan acquired pursuant to this paragraph, and thereafter payments in respect of such Swingline Loan shall be made to the Administrative Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from the Borrower (or other party on behalf of the Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Administrative Agent; any such amounts received by the Administrative Agent shall be promptly remitted by the Administrative Agent to the Revolving Lenders that shall have made their payments pursuant to this paragraph and to the Swingline Lender, as their interests may appear, provided that any such payment so remitted shall be repaid to the Swingline Lender or to the Administrative Agent, as applicable, if and to the extent such payment is required to be refunded to the Borrower for any reason. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not relieve the Borrower of any default in the payment thereof.

SECTION 2.05. Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of Letters of Credit for its own account (or for the account of any of its Restricted Subsidiaries so long as the Borrower is a co-applicant), in a form reasonably acceptable to the Administrative Agent and the Issuing Bank, at any time and from time to time during the Revolving Availability Period. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control. All Existing Letters of Credit shall be deemed to be issued hereunder and shall constitute Letters of Credit subject to the terms hereof and, to the extent previously issued for the account of a Restricted Subsidiary of the Borrower, shall constitute an obligation of the Borrower pursuant to this Agreement.

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the Issuing Bank) to the Issuing Bank and the Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with Section 2.05(c)), 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 Bank, the Borrower also shall submit a letter of credit application on the Issuing Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension, (i) the LC Exposure shall not exceed $10,000,000 and (ii) the aggregate Revolving Exposures shall not exceed the aggregate Revolving Commitments.

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date that is one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) ten days prior to the Revolving Maturity Date; provided that at the option of the Issuing Bank any Letter of Credit having a tenor of one year or greater may provide for the renewal of such Letters of Credit for additional one year periods so long as such renewal period does not end after the date described in clause (ii).

(d) Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Revolving Lender, and each Revolving Lender hereby acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable 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 Bank, such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided in Section 2.05(e), 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 Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If the Issuing Bank 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 12:00 noon, New York City time, on the Business Day immediately following the day that the Borrower shall have received notice of such LC Disbursement; provided that, if such LC Disbursement is not less than $250,000, the Borrower may, subject to the conditions to borrowing set forth herein, request (and, if the Borrower fails to reimburse such LC Disbursement when due, the Borrower shall be deemed to have requested) in accordance with Section 2.04 that such LC Disbursement be financed with a 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 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 Applicable Percentage thereof. Promptly following receipt of such notice, each Revolving Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.06 with respect to Loans made by such Lender (and Section 2.06 shall apply, mutatis mutandis, to the payment obligations of the Revolving Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank 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 Bank or, to the extent that Revolving Lenders have made payments pursuant to this paragraph to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Revolving Lender pursuant to this paragraph to reimburse the Issuing Bank for any LC Disbursement (other than the funding of 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.

(f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in Section 2.05(e) 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 Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.05, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank, provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential or punitive 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 Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof or the Issuing Bank’s willful misconduct or gross negligence. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented that appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder, provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Revolving Lenders with respect to any such LC Disbursement in accordance with Section 2.05(e).

(h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and 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 2.05(e), then Section 2.13(c) shall apply. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Revolving Lender pursuant to Section 2.05(e) to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment.

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

(j) Cash Collateralization. If 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, Revolving Lenders with LC Exposure representing greater than 50% of the aggregate LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Collateral Agent, in the name of the Collateral Agent and for the benefit of the Lenders, an amount in cash equal to 105% the LC Exposure 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 7.01(h) or (i). The Borrower also shall deposit cash collateral pursuant to this paragraph as and to the extent required by Section 2.11(b). Each 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 Administrative 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 Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Revolving Lenders with LC Exposure representing greater than 50% of the aggregate LC Exposure), be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived.

(k) Additional Issuing Banks. The Borrower may at any time, and from time to time, designate one or more additional Lenders to act as an issuing bank under this Agreement with the consent of the Administrative Agent and, if Fifth Third Bank is an Issuing Bank, Fifth Third Bank (which consent, in each case, shall not be unreasonably withheld) and such Lender. Any Lender designated as an issuing bank pursuant to this Section 2.05(k) shall be deemed to be and shall have all the rights and obligations of an “Issuing Bank” hereunder.

SECTION 2.06. Funding of Borrowings.

(a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 12:00 noon, New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders, provided that Swingline Loans shall be made as provided in Section 2.04. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Administrative Agent in New York City and designated by the Borrower in the applicable Borrowing Request, provided that ABR Revolving Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.05(e) shall be remitted by the Administrative Agent to the Issuing Bank.

(b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.06(a) and may, in reliance upon such assumption and in its sole discretion, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation

or (ii) in the case of the Borrower, the interest rate applicable to such Borrowing. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

SECTION 2.07. Interest Elections.

(a) Each Revolving Borrowing and Term Loan Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request or as designated by Section 2.03. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section 2.07. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. This Section 2.07 shall not apply to Swingline Borrowings, which may not be converted or continued.

(b) To make an election pursuant to this Section 2.07, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Revolving Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request signed by the Borrower.

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

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

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

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

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

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration.

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

(e) If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall (i) in the case of a Revolving Borrowing, be converted to an ABR Borrowing and (ii) in the case of a Term Borrowing, be continued as a Eurodollar Borrowing with an Interest Period of one month.

(f) Notwithstanding any contrary provision hereof, if a payment Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as such Event of Default is continuing, (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

SECTION 2.08. Termination and Reduction of Commitments.

(a) Unless previously terminated, (i) the Tranche A Commitments shall terminate at 5:00 p.m., New York City time, on the Effective Date, (ii) the Tranche B Commitments shall terminate at 5:00 p.m., New York City time, on the Effective Date and (iii) the Revolving Commitments shall terminate at the start of the Revolving Maturity Date.

(b) The Borrower may at any time terminate, or from time to time reduce, the Commitments of any Class, provided that (i) each reduction of the Commitments of any Class shall be in an amount that is an integral multiple of $500,000 and not less than $1,000,000 and (ii) the Borrower shall not terminate or reduce the Revolving Commitments if, after giving effect to any concurrent prepayment of the Revolving Loans in accordance with Section 2.11, the aggregate Revolving Exposures would exceed the aggregate Revolving Commitments.

(c) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under Section 2.08(b) at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section 2.08 shall be irrevocable, provided that a notice of termination of the Revolving Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities or the consummation of any other event, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Commitments of any Class shall be permanent. Each reduction of the Commitments of any Class shall be made ratably among the Lenders in accordance with their respective Commitments of such Class.

SECTION 2.09. Repayment of Loans; Evidence of Debt.

(a) The Borrower hereby unconditionally promises to pay (i) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Revolving Loan of such Lender on the Revolving Maturity Date, (ii) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Tranche A Term Loan of such Lender as provided in Section 2.10, (iii) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Tranche B Term Loan of such Lender as provided in Section 2.10 and (iv) the then unpaid principal amount of each Swingline Loan on the earlier of the Revolving Maturity Date and the first date after such Swingline Loan is made that is the 15th or last day of a calendar month and is at least two Business Days after such Swingline Loan is made; provided that on each date that a Revolving Borrowing is made, the Borrower shall repay all Swingline Loans then outstanding.

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

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

(d) The entries made in the accounts maintained pursuant to Section 2.09(b) and (c) 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 of any Class made by it be evidenced by a Note. In such event, the Borrower shall prepare, execute and deliver to such Lender a Note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns). Thereafter, the Loans evidenced by such Notes and interest thereon shall at all times (including after assignment pursuant to Section 9.04) be represented by one or more Notes in such form payable to the order of the payee named therein (or, if such Note is a registered note, to such payee and its registered assigns).

(c) To the extent not previously paid, all Tranche B Term Loans shall be due and payable on the Tranche B Maturity Date. To the extent not previously paid, all Tranche A Term Loans shall be due and payable on the Tranche A Maturity Date.

(d) Any mandatory prepayment of a Term Loan Borrowing shall be applied to reduce, in the direct order of maturity, the scheduled repayments of the Term Loan Borrowings to be made pursuant to this Section 2.10 on the scheduled payment dates next following the date of such prepayment, unless and until each such scheduled repayment has been eliminated as a result of reductions hereunder. Any optional prepayment of a Term Loan Borrowing shall be applied as directed by the Borrower to do one of the following: (i) to reduce in the direct order of maturity the scheduled repayments of the Term Loan Borrowings to be made pursuant to this Section 2.10, (ii) to reduce in the inverse order of maturity the scheduled repayments of the Term Loan Borrowings to be made pursuant to this Section 2.10 or (iii) to reduce ratably the remaining scheduled repayments of the Term Loan Borrowings.

SECTION 2.11. Prepayment of Loans.

(a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to the requirements of this Section 2.11.

(b) In the event and on such occasion that the aggregate Revolving Exposures exceeds the aggregate Revolving Commitments, the Borrower shall prepay Revolving Borrowings or Swingline Borrowings (or, if no such Borrowings are outstanding, deposit cash collateral in an account with the Collateral Agent pursuant to Section 2.05(j)) in an aggregate amount equal to such excess.

(c) In the event and on each occasion that any Net Proceeds are received by or on behalf of Holdings, the Borrower or any Restricted Subsidiary in respect of any Prepayment Event, the Borrower shall, promptly after such Net Proceeds are received by Holdings, the Borrower or such Restricted Subsidiary (and in any event not later than the fifth Business Day after such Net Proceeds are received), prepay Term Loan Borrowings in an aggregate amount equal to 100% of such Net Proceeds; provided that in the case of any event described in clause (a) or (b) of the definition of the term “Prepayment Event” (other than if the event generating such Net Proceeds is a disposition made pursuant to Section 6.05 (m)), if the Borrower shall deliver to the Administrative Agent a certificate of a Financial Officer to the effect that the Borrower and the Restricted Subsidiaries intend to apply the Net Proceeds from such event (or a portion thereof specified in such certificate), within 365 days after receipt of such Net Proceeds, to acquire or replace real property, equipment or other tangible assets (excluding inventory) to be used in the business of the Borrower and the Restricted Subsidiaries, and certifying that no Event of Default has occurred and is continuing, then no prepayment shall be required pursuant to this paragraph in respect of the Net Proceeds specified in such certificate, except to the extent that the aggregate amount of such Net Proceeds that have not been so applied or contractually committed in writing by the end of such 365-day period (and, if so contractually committed in writing but not applied prior to the end of such 365-day period, applied within 180 days of the end of such period), promptly after which time a prepayment shall be required in an amount equal to such Net Proceeds.

(d) Following the end of each fiscal year of the Borrower, commencing with the fiscal year ending December 31, 2008, the Borrower shall prepay Borrowings in an aggregate amount equal to:

(x) the excess of (A) 50% of Excess Cash Flow over (B) prepayments of Loans under Section 2.11(a) during such fiscal year (other than prepayments funded with the proceeds of incurrences of Indebtedness and in the case of prepayments of Revolving Loans only so long as the corresponding Commitments are reduced permanently) for any fiscal year for which the Leverage Ratio at the end of such fiscal year is greater than 5.00 to 1.00,

(y) the excess of (A) 25% of Excess Cash Flow over (B) prepayments of Loans under Section 2.11(a) during such fiscal year for any fiscal year (other than prepayments funded with the proceeds of incurrences of Indebtedness and in the case of prepayments of Revolving Loans only so long as the corresponding Commitments are reduced permanently) for which the Leverage Ratio at the end of such fiscal year is less than or equal to 5.00 to 1.00 and greater than 4.00 to 1.00 and

(z) none of Excess Cash Flow for any fiscal year for which the Leverage Ratio at the end of such fiscal year is less than or equal to 4.00 to 1.00.

Each prepayment pursuant to this paragraph shall be made within five Business Days of the date on which financial statements are delivered pursuant to Section 5.01 with respect to the fiscal year for which Excess Cash Flow is being calculated (and in any event within 95 days after the end of such fiscal year).

(e) Prior to any optional or mandatory prepayment of Borrowings hereunder, the Borrower shall determine in accordance with Section 2.10(d) the Borrowing or Borrowings to be prepaid and shall specify such determination in the notice of such prepayment pursuant to Section 2.11(f).

(f) The Borrower shall notify the Administrative Agent (and, in the case of prepayment of a Swingline Loan, the Swingline Lender) by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York City time, three Business Days before the date of prepayment, (ii) in the case of prepayment of an ABR Borrowing, not later than 11:00 a.m., New York City time, on the date of prepayment or (iii) in the case of prepayment of a Swingline Loan, not later than 2:00 p.m., New York City time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date, the principal amount of each Borrowing or portion thereof to be prepaid and, in the case of a mandatory prepayment, a reasonably detailed calculation of the amount of such prepayment, provided that if a notice of prepayment states that such notice is conditioned on the effectiveness of other credit facilities or the consummation of any other event, then such notice of prepayment may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Promptly following receipt of any such notice (other than a notice relating solely to Swingline Loans), the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02, except as necessary to apply fully the required amount of a mandatory prepayment. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.13 but shall in no event include premium or penalty. All prepayments of Term Loans under this Section 2.11 shall be made pro rata amongst the Tranche A Term Loans and the Tranche B Term Loans outstanding at the time of such prepayment and then with respect to such Term Loans, in accordance with Section 2.10(d). Notwithstanding the foregoing any Tranche B Lender may elect, by written notice to the Administrative Agent at least one Business Day prior to the prepayment date, to decline all or any portion of any prepayment of its Trance B Term Loans, pursuant to this Section 2.11, in which case the aggregate amount of the prepayment that would have been applied to prepay such Tranche B Term Loans, but was so declined shall be applied to prepay the Tranche A Term Loans then outstanding pro rata amongst all the Tranche A Term Loans outstanding , in accordance with Section 2.10(d) and, following repaying in full of all Tranche A Term Loans, such amount shall be retained by Borrower.

(g) All Swap Agreements, if any, between Borrower and any of the Lenders or their respective affiliates are independent agreements governed by the written provisions of said Swap

Agreements, which will remain in full force and effect, unaffected by any repayment, prepayment, acceleration, reduction, increase or change in the terms of the Loans, except as otherwise expressly provided in said written Swap Agreements, and any payoff statement from the Lenders relating to the Loans shall not apply to said Swap Agreements except as otherwise expressly provided in such payoff statement.

SECTION 2.12. Fees.

(a) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee, which shall accrue at the Applicable Rate on the average daily unused amount of the Revolving Commitment of such Lender during the period from and including the Effective Date to but excluding the date on which the aggregate Revolving Commitments terminate. Accrued commitment fees shall be payable in arrears in respect of the Revolving Commitments on the last Business Day of March, June, September and December of each year and on the date on which the Revolving Commitments terminate, commencing on the first such date to occur after the date hereof. All commitment fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). For purposes of computing commitment fees with respect to Revolving Commitments, a Revolving Commitment of a Lender shall be deemed to be used to the extent of the outstanding Revolving Loans and LC Exposure of such Lender (and the Swingline Exposure of such Lender shall be disregarded for such purpose).

(b) The Borrower agrees to pay (i) to the Administrative Agent for the account of each Revolving Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Rate used to determine the interest rate applicable to Eurodollar Revolving Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Revolving Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank a fronting fee, which shall accrue at a rate equal to 0.125% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Revolving Commitments and the date on which there ceases to be any LC Exposure, as well as the Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees shall be payable on the last Business Day of March, June, September and December of each year, commencing on the first such date to occur after the Effective Date, provided that all such fees shall be payable on the date on which the Revolving Commitments terminate and any such fees accruing after the date on which the Revolving Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be payable within 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

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

(d) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for distribution, in the case of commitment fees and participation fees, to the Lenders entitled thereto. Fees paid shall not be refundable under any circumstances.

SECTION 2.13. Interest.

(a) The Loans comprising each ABR Borrowing (including each Swingline Loan) shall bear interest at the Alternate Base Rate plus the Applicable Rate.

(b) The Loans comprising each Eurodollar Borrowing shall bear interest at the LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate.

(c) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section 2.13 or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Revolving Loans as provided in Section 2.13(a).

(d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and, in the case of Revolving Loans, upon termination of the Revolving Commitments, provided that (i) interest accrued pursuant to Section 2.13(c) shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Revolving Loan prior to the end of the Revolving Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

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

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

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

(b) the Administrative Agent is advised by the Required Lenders that the LIBO Rate for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period;

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

SECTION 2.15. Increased Costs.

(a) If any Change in Law shall:

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

(ii) impose on any Lender or the Issuing Bank or the London interbank market any other condition (other than attributable to Taxes or Other Taxes) affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein;

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

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

(c) The Borrower shall pay to each Lender, (i) as long as such Lender shall be required to maintain reserves with respect to liabilities or assets consisting of or including Eurodollar funds or deposits, additional interest on the unpaid principal amount of each Eurodollar Loan equal to the actual costs of such reserves allocated to such Loan by such Lender (as determined by such Lender in good faith, which determination shall be conclusive in the absence of manifest error), and (ii) as long as such Lender shall be required to comply with any reserve ratio requirement or analogous requirement of any other central banking or financial regulatory authority imposed in respect of the maintenance of the Commitments or the funding of the Eurodollar Loans, such additional costs (expressed as a percentage per annum and rounded upwards, if necessary, to the nearest five decimal places) equal to the actual costs allocated to such Commitment or Loan by such Lender (as determined by such Lender in good faith, which determination shall be conclusive absent manifest error) which in each case shall be due and payable on each date on which interest is payable on such Loan, provided the Borrower shall have received at least fifteen (15) days’ prior notice (with a copy to the Administrative Agent, and which notice shall specify the Statutory Reserve Rate, if any, applicable to such Lender) of such additional interest or cost from such Lender. If a Lender fails to give notice fifteen (15) days prior to the relevant Interest Payment Date, such additional interest or cost shall be due and payable fifteen (15) days from receipt of such notice.

(d) A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as applicable, as specified in Section 2.15(a), (b) or (c) shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or the Issuing Bank, as applicable, the amount shown as due on any such certificate within 10 days after receipt thereof.

(e) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 2.15 shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section 2.15 for any increased costs or reductions incurred more than 270 days prior to the date that such Lender or the Issuing Bank, as applicable, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor, provided, further, that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

SECTION 2.16. Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Revolving Loan or Term Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.11(f) and is revoked in accordance therewith), or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.19, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest that would have accrued on the principal amount of such Loan had such event not occurred, at the LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest that would accrue on such principal amount for such period at the interest rate that such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section 2.16 shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. Notwithstanding the foregoing, no additional amounts shall be due and payable pursuant to this Section 2.16 to the extent that on the relevant due date the Borrower deposits in a Prepayment Account an amount equal to any payment of Eurodollar Loans otherwise required to be made on a date that is not the last day of the applicable Interest Period; provided that on the last day of the applicable Interest Period, the Administrative Agent shall be authorized, without any further action by or notice to or from the Borrower or any other Loan Party, to apply such amount to the prepayment of such Eurodollar Loans. For purposes of this Agreement, the term “Prepayment Account” shall mean a non-interest bearing account established by the Borrower with the Administrative Agent and over which the Administrative Agent shall have exclusive dominion and control, including the right of withdrawal for application in accordance with this Section 2.16. Anything to the contrary contained herein notwithstanding, no Lender nor any Participant is required to match fund any Obligation and the provisions of this Section 2.16 shall apply as if match funding had occurred by acquiring Eurodollar deposits for each Interest Period in the amount of the applicable Eurodollar Loans.

SECTION 2.17. Taxes.

(a) Any and all payments by or on account of any obligation of any Loan Party hereunder or under any other Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes, provided that if any Loan Party shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.17) the Administrative Agent, Lender or Issuing Bank (as applicable) receives an amount equal to the amount it would have received had no such deductions been made, (ii) such Loan Party shall make such deductions and (iii) such Loan Party shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

(c) The applicable Loan Party shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within 10 Business Days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as applicable, on or with respect to any payment by or on account of any obligation of the Borrower hereunder or under any other Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 2.17) and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate setting forth in reasonable detail the amount of such payment or liability delivered to the Borrower by a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error.

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

(e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the United States, or any treaty to which the United States is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), on or prior to the Effective Date in the case of each Foreign Lender that is a signatory hereto, and on the date of assignment pursuant to which it becomes a Lender in the case of each other Lender and from time to time thereafter as reasonably requested by either of the Borrower or the Administrative Agent, such properly completed, original and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate. Each Lender that is a U.S. Person within the meaning of Section 7701(a)(30) of the Code on or prior to the date of its execution and delivery of this Agreement, on or prior to the date on which it becomes a Lender, in the case of an assignee, and from time to time thereafter if requested in writing by the Borrower or the Administrative Agent, shall provide the Borrower and the Administrative Agent with duplicate executed originals of Internal Revenue Service Form W-9, or any successor form, certifying that such Lender is entitled to exemption from United States backup withholding tax.

(f) If the Administrative Agent or a Lender determines, in its reasonable discretion, that it has received a refund of any 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 2.17, 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 2.17 with respect to the 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. This Section 2.17 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 that it deems confidential) to the Borrower or any other Person. Notwithstanding anything contained herein to the contrary, in no event will the Administrative Agent or any Lender be required to pay any amount to the Borrower the payment of which would place such Administrative Agent or 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 Indemnified Taxes or Other Taxes had never been paid.

(g) To the extent required by any applicable law, the Administrative Agent may withhold from any payment to any Lender an amount equivalent to any applicable withholding tax. If the Internal Revenue Service or any authority of the U.S. or other jurisdiction asserts a claim that the Administrative Agent did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered or properly executed, or because such Lender failed to notify the Administrative Agent of a change in circumstances that rendered the exemption from, or reduction of, withholding tax ineffective, or for any other reason), such Lender shall indemnify the Administrative Agent (to the extent that the Administrative Agent has not already been reimbursed by the Loan Parties and without limiting the obligation of the Loan Parties to do so) fully for all amounts paid, directly or indirectly, by the Administrative Agent as Tax or otherwise, including penalties and interest, together with all expenses incurred.

SECTION 2.18. Payments Generally; Pro Rata Treatment; Sharing of Setoffs.

(a) The Borrower shall make each payment required to be made by it hereunder or under any other Loan Document (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.15, 2.16 or 2.17, or otherwise) prior to the time expressly required hereunder or under such other Loan Document for such payment (or, if no such time is expressly required, prior to 3:00 p.m., New York City time), on the date when due, in immediately available funds, without setoff or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at 4 World Financial Center, 250 Vesey Street New York, NY 10080, except payments to be made directly to the Issuing Bank or Swingline Lender as expressly provided herein and except that payments pursuant to Sections 2.15, 2.16, 2.17 and 9.03 shall be made directly to the Persons entitled thereto and payments pursuant to other Loan Documents shall be made to the Persons specified therein. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment under any Loan Document shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments under each Loan Document shall be made in dollars.

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

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

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

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.04(c), 2.05(d) or (e), 2.06(a), 2.18(d) or 9.03(c), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

SECTION 2.19. Mitigation Obligations; Replacement of Lenders.

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

(b) If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, or if any Lender defaults in its obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent (and if a Revolving Commitment is being assigned, the Issuing Bank and the Swingline Lender), which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements and Swingline Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will result in a material reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

SECTION 2.20. Incremental Extensions of Credit. At any time during the Revolving Availability Period, subject to the terms and conditions set forth herein, the Borrower may at any time and from time to time, by notice to the Administrative Agent (whereupon the Administrative Agent shall promptly deliver a copy to each of the Lenders), request to add additional term loans or additional revolving commitments (together, the “Incremental Extensions of Credit”) in minimum principal amounts of $5,000,000; provided that such amount may be less than $5,000,000 if such amount represents all the remaining availability under the aggregate principal amount set forth below; provided, further, that (x) immediately prior to and after giving effect to any Incremental Facility Amendment (as defined below), no Event of Default has occurred or is continuing or shall result therefrom, (y) the Senior Secured Leverage Ratio on a Pro Forma Basis as of the last day of the most recent period in respect of which financial statements shall have been required to be delivered pursuant to Section 5.01(a) or (b) (or if prior to the first time such financial statements are so required to be delivered, as of the last day of the most recent period in respect of which financial statements of the Borrower and its Restricted Subsidiaries are available) shall not exceed a ratio that is 0.25 less than the ratio specified in Section 6.12 for such last day (it being understood that if such last day is prior to March 31, 2008, then the ratio specified for March 31, 2008 under Section 6.12 shall be deemed to be the ratio specified in Section 6.12 for such last day) and (z) the Borrower shall have delivered to the Administrative Agent an officer’s certificate to the effect set forth in clauses (x) and (y) above. The Incremental Extensions of Credit:

(a) shall be in an aggregate principal amount not exceeding $50,000,000 since the Effective Date, and

(b) shall rank pari passu in right of payment and right of security with the Revolving Loans and Term Loans in respect of the Collateral;

provided that (i) the Incremental Extensions of Credit in the form of term loans shall not have a final maturity date earlier than the Tranche B Maturity Date, (ii) the Incremental Extensions of Credit in the form of revolving loans shall not have a final maturity date earlier than the Revolving Maturity Date, (iii) the Incremental Extensions of Credit in the form of term loans shall not have a weighted average life that is shorter than that of the then-remaining weighted average life of the existing Tranche B Term Loans (without giving effect to any reductions of such weighted average life caused by voluntary or mandatory prepayments of Tranche B Term Loans pursuant to Section 2.11) and (iv) the Incremental Extensions of Credit shall be, in the case of revolving loan extensions, on the terms and pursuant to the documentation applicable to the Revolving Loans. The Borrower shall by written notice offer each Lender (an “Existing Lender”) the opportunity for no less than ten (10) Business Days after delivery of the notice to commit to provide its pro rata portion (based on the amount of its outstanding Tranche A Term Loans, Tranche B Term Loans or outstanding Revolving Loans and unused Revolving Commitments, as applicable, on the date of such notice) of any requested Incremental Extension of Credit, provided that no Existing Lender shall be obligated to provide any Incremental Extension of Credit unless it so agrees. Any additional bank, financial institution, Existing Lender or other Person that elects to extend Incremental Extensions of Credit shall be reasonably satisfactory to the Borrower and the Administrative Agent and, in the case of Incremental Extensions of Credit in the form of revolving loans, the Issuing Bank (any such bank, financial institution, Existing Lender or other Person being called an “Additional Lender”) and shall become a Lender under this Agreement pursuant to an amendment (an “Incremental Facility Amendment”) to this Agreement giving effect to the modifications permitted by this Section 2.20 and, as appropriate, the other Loan Documents and executed by the Borrower, each Additional Lender and the Administrative Agent. Commitments in respect of Incremental Extensions of Credit shall be Commitments under this Agreement. An Incremental Facility Amendment 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 2.20 (including voting provisions applicable to the Additional Lenders comparable to the provisions of clause (B) of the second proviso of Section 9.02(b)). The effectiveness of any Incremental Facility Amendment shall be subject to the satisfaction on the date thereof (each, an “Incremental Facility Closing Date”) of each of the conditions set forth in Section 4.02 (it being understood that all references to “the date of such Borrowing” in such Section 4.02 shall be deemed to refer to the Incremental Facility Closing Date). The proceeds of the Incremental Extensions of Credit shall be used for working capital and general corporate purposes (including Permitted Acquisitions).

ARTICLE III

Representations and Warranties

The Borrower and Holdings represent and warrant to the Lenders (it being understood and agreed that the representations and warranties made on or prior to the Effective Date are deemed made concurrently with, and after giving effect to, the consummation of the Transactions on the Effective Date) that:

SECTION 3.01. Organization; Power. Each Loan Party (a) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, (b) except where the

failure to do so, individually or in the aggregate, is not reasonably likely to result in a Material Adverse Effect, (i) has the power and authority and all governmental rights, qualifications, approvals, authorizations, permits, accreditations, Reimbursement Approvals, licenses and franchises material to the business of the Borrower and the Subsidiaries taken as a whole that are necessary to own its assets, to carry on its business as now conducted and as proposed to be conducted and to execute, deliver and perform its obligations under each Loan Document to which it is a party and (ii) is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required.

SECTION 3.02. Authorization; Enforceability. The Transactions to be entered into by each Loan Party have been duly authorized by all necessary corporate or other action and, if required, stockholder action. This Agreement has been duly executed and delivered by each of Holdings and the Borrower and constitutes, and each other Loan Document to which any Loan Party is to be a party, when executed and delivered by such Loan Party, will constitute, a legal, valid and binding obligation of Holdings, the Borrower or such Loan Party, as applicable, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

SECTION 3.03. Governmental Approvals; No Conflicts. Except as set forth in Schedule 3.03 the Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as have been obtained or made and are in full force and effect and except those that are required or permitted to be obtained following consummation of the Transactions, the absence of which individually or in the aggregate are not reasonably likely to result in a Material Adverse Effect and filings necessary to perfect Liens created under the Loan Documents, (b) will not violate any Requirement of Law applicable to Holdings, the Borrower or any of the Subsidiaries, as applicable, except as is not reasonably likely to result in, individually or in the aggregate, a Material Adverse Effect, (c) will not violate or result in a default under any indenture or other material agreement or instrument binding upon Holdings, the Borrower or any of the Subsidiaries or its assets, except as is not reasonably likely to result in, individually or in the aggregate, a Material Adverse Effect, (d) will not result in a Limitation on any right, qualification, approval, permit, accreditation, authorization, Reimbursement Approval, license or franchise or authorization granted by any Governmental Authority, Third Party Payor or other Person applicable to the business, operations or assets of the Borrower or any of the Subsidiaries or adversely affect the ability of the Borrower or any of the Subsidiaries to participate in any Third Party Payor Arrangement except for Limitations, individually or in the aggregate, as are not reasonably likely to result in a Material Adverse Effect, and (e) will not result in the creation or imposition of any Lien on any asset of Holdings, the Borrower or any of the Subsidiaries, except Liens created under the Loan Documents. There is no pending or, to the knowledge of the Borrower, threatened Limitation by any Governmental Authority, Third Party Payor or any other Person of any right, qualification, approval, permit, authorization, accreditation, Reimbursement Approval, license or franchise of the Borrower, or any Subsidiary, except for such Limitations, individually or in the aggregate, as are not reasonably likely to result in a Material Adverse Effect. No certifications by any Governmental Authority or any Third Party Payor are required for operation of the business of the Borrower and the Subsidiaries that are not in place, except for such certifications or agreements, the absence of which do not materially and adversely affect the operation of the business.

SECTION 3.04. Financial Condition; No Material Adverse Change.

(a) The Borrower has heretofore furnished to the Lenders its consolidated balance sheet and consolidated statements of operations and comprehensive income, stockholders’ equity and cash flows as of and for the fiscal years ended December 31, 2004, December 31, 2005, and

December 31, 2006, reported on by Ernst & Young LLP, independent public accountants. Such financial statements present fairly, in all material respects, the financial position and results of operations and cash flows of the Borrower and its subsidiaries as of such dates and for such periods in accordance with GAAP consistently applied.

(b) The Borrower has heretofore furnished to the Lenders its pro forma consolidated balance sheet as of June 30, 2007 prepared giving effect to the Transactions as if the Transactions had occurred on such date. Such pro forma consolidated balance sheet (i) has been prepared in good faith based on assumptions (which are believed by the Borrower to be reasonable), (ii) accurately reflects all adjustments necessary to give effect to the Transactions and (iii) presents fairly, in all material respects, the pro forma financial position of the Borrower and its subsidiaries as of June 30, 2007 as if the Transactions had occurred on such date.

(c) No event, change, condition or state of facts has occurred that has resulted in, or is reasonably likely to result in, individually or in the aggregate, a Material Adverse Effect since December 31, 2006.

SECTION 3.05. Properties.

(a) Each of Holdings, the Borrower and the Subsidiaries has good title to, or valid leasehold interests in, all its real property material to its business, except for such defects in title as could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, free and clear of all Liens, except for Liens expressly permitted pursuant to Section 6.02.

(b) Schedule 3.05 sets forth the address of each real property owned by any of the Loan Parties as of the Effective Date after giving effect to the Transactions.

SECTION 3.06. Litigation. Except as set forth on Schedule 3.06, there are no actions, suits or proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of Holdings and the Borrower, threatened against or affecting Holdings, the Borrower or any Subsidiary that would reasonably be likely to, individually or in the aggregate, (i) result in a Material Adverse Effect or (ii) adversely affect in any material respect the ability of the Loan Parties to consummate the Transactions or the other transactions contemplated hereby.

SECTION 3.07. Compliance with Laws. Except as is not reasonably likely to result in, individually or in the aggregate, a Material Adverse Effect, each of Holdings, the Borrower and the Subsidiaries is in compliance with all Requirements of Law applicable to it or its property.

SECTION 3.08. Investment Company Status. No Loan Party is required to be registered as an “investment company” as defined in the Investment Company Act of 1940, as amended.

SECTION 3.09. Taxes. Each of Holdings, the Borrower and the Subsidiaries has timely filed or caused to be filed all Federal income and other material income Tax returns and reports required to have been filed and has paid or caused to be paid all Taxes shown to be due and payable on such returns or on any assessments made by it, including in their capacity as withholding agent, except any Taxes that are being contested in good faith by appropriate proceedings for which Holdings, the Borrower or such Subsidiary, as applicable, has set aside on its books adequate reserves in accordance with GAAP or to the extent that the failure to pay such Taxes so is not reasonably likely, individually or in the aggregate, to result in a Material Adverse Effect. Each of Holdings, the Borrower and the Subsidiaries has made adequate provision in accordance with GAAP for all Taxes not yet due and payable. None of

Holdings, the Borrower and the Subsidiaries is aware of any proposed or pending Tax assessment, deficiency or audit that would reasonably be expected to, individually or in the aggregate, result in a Material Adverse Effect.

SECTION 3.10. ERISA. No ERISA Event has occurred, or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, is reasonably likely, individually or in the aggregate, to result in a Material Adverse Effect. Except as would not be reasonably likely, individually or in the aggregate, to result in a Material Adverse Effect, the present value of all accumulated benefit obligations under each Plan (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 value of the assets of such Plan. Except as would not be reasonably likely to result in, individually or in the aggregate, a Material Adverse Effect, each employee benefit plan maintained or contributed to by the Borrower or any Subsidiary and each Plan is in compliance with the applicable provisions of ERISA and the Code. Using actuarial assumptions and computation methods consistent with subpart 1 of subtitle E of Title IV of ERISA, the aggregate liabilities of each ERISA Affiliate to all Multiemployer Plans in the event of a complete withdrawal therefrom, as of the close of the most recent fiscal year of each such Multiemployer Plan, are not reasonably likely, individually or in the aggregate, to result in a Material Adverse Effect.

SECTION 3.11. Disclosure. Neither the Information Memorandum nor any of the other reports, financial statements, certificates or other information furnished by or on behalf of any Loan Party to the Administrative Agent or any Lender in connection with the negotiation of this Agreement or any other Loan Document or delivered hereunder or thereunder (as modified or supplemented by other information so furnished and taken as a whole) contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, provided that the foregoing shall not apply to any projected financial information, and with respect to such projected financial information, Holdings and the Borrower represent only that such information was prepared in good faith based upon assumptions believed by them to be reasonable at the time delivered and as of the Effective Date.

SECTION 3.12. Subsidiaries. After giving effect to the Merger, as of the Effective Date, Holdings does not have any subsidiaries other than the Borrower and the Subsidiaries and Inactive Subsidiaries listed on Schedule 3.12. Schedule 3.12 sets forth the name of, and the ownership or beneficial interest of Holdings in, each subsidiary, including the Borrower, and identifies each Subsidiary that is a Subsidiary Loan Party, in each case as of the Effective Date.

SECTION 3.13. [Reserved].

SECTION 3.14. Labor Matters. As of the Effective Date, there are no strikes, lockouts or slowdowns against Holdings, the Borrower or any Subsidiary pending or, to the knowledge of Holdings and the Borrower, threatened, that would reasonably be expected to, individually or in the aggregate, result in a Material Adverse Effect.

SECTION 3.15. Solvency. Immediately after the consummation of the Transactions to occur on the Effective Date, (a) the fair value of the assets of the Loan Parties, taken as a whole, at a fair valuation, will exceed their debts and liabilities, subordinated, contingent or otherwise, (b) the present fair saleable value of the property of the Loan Parties, taken as a whole, will be greater than the amount that will be required to pay the probable liability of their debts and other liabilities, subordinated, contingent or otherwise, as

such debts and other liabilities become absolute and matured, (c) the Loan Parties, taken as a whole, will be able to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured, and (d) the Loan Parties, taken as a whole, will not have unreasonably small capital with which to conduct the business in which they are engaged as such business is now conducted and is proposed to be conducted following the Effective Date, in each case after giving effect to any rights of indemnification, contribution or subrogation arising among the Subsidiary Loan Parties pursuant to the Collateral Agreement or by law.

SECTION 3.16. [Reserved].

SECTION 3.17. Reimbursement from Third Party Payors.

(a) The Borrower may at any time after the Effective Date designate any Restricted Subsidiary of the Borrower as an Unrestricted Subsidiary or any Unrestricted Subsidiary as a Restricted Subsidiary; provided that (i) immediately before and after such designation on a Pro Forma Basis, no Default shall have occurred and be continuing, (ii) immediately after giving effect to such designation, the Borrower shall be in compliance, on a Pro Forma Basis, with the Financial Performance Covenant as of the last day of the most recent period in respect of which financial statements shall have been required to be delivered pursuant to Section 5.01(a) or (b) (or if prior to the first time such financial statements are so required to be delivered, as of the last day of the most recent period for which financial statements of the Borrower and its Restricted Subsidiaries are available); it being understood that if such last day is prior to March 31, 2008, then the ratio specified for March 31, 2008 under Section 6.12 shall be deemed to apply (it being understood that as a condition precedent to the effectiveness of any such designation, the Borrower shall deliver to the Administrative Agent a certificate of a Financial Officer setting forth in reasonable detail the calculations demonstrating such compliance), (iii) no Subsidiary may be designated as an Unrestricted Subsidiary or continue as an Unrestricted Subsidiary if (A) it is a “Restricted Subsidiary” for the purpose of the Bridge Loan Credit Agreement or any other Indebtedness of Holdings or the Borrower or (B) the Borrower or any Restricted Subsidiary provides any Guarantee or credit support of any kind, including any undertaking, Guarantee, indemnity, agreement or instrument that would constitute Indebtedness (other than the pledge of Equity Interests of Unrestricted Subsidiaries) of any Indebtedness of such Unrestricted Subsidiary or is directly or indirectly liable on such Indebtedness, as a guarantor or otherwise or any Indebtedness of such Unrestricted Subsidiary contains a default that would permit, upon notice, lapse of time or both, any holder of any Indebtedness of Borrower or any Restricted Subsidiary to declare a default under such other Indebtedness or cause the payment thereof to be accelerated or payable prior to its stated maturity, and (iv) if a Restricted Subsidiary is being designated as an Unrestricted Subsidiary hereunder, the sum of (A) the assets of such Subsidiary as of such date of designation (the “Designation Date”), as set forth on such Subsidiary’s most recent balance sheet, plus (B) the aggregate amount of assets of all Unrestricted Subsidiaries designated as Unrestricted Subsidiaries pursuant to this Section 5.15(a) prior to the Designation Date (in each case measured as of the date of each such Unrestricted Subsidiary’s designation as an Unrestricted Subsidiary), together with the amount of all Investments outstanding pursuant to Section 6.04(i) and Section 6.04(xv), as of the Designation Date shall not exceed $20,000,000 (net of cash returns on such Investments to the Borrower or a Qualified Restricted Subsidiary) during any period of 12 consecutive months (with any amount not used during such period permitted to be carried forward to any subsequent period) as of the Designation Date on a pro forma basis for such designation. The designation of any Subsidiary as an Unrestricted Subsidiary after the Effective Date shall constitute an Investment by the Borrower therein at the date of designation in an amount equal to the net book value of the Borrower’s or its Subsidiary’s (as applicable) investment therein. The designation of any Unrestricted Subsidiary as a Restricted Subsidiary shall constitute (i) the incurrence at the time of designation of any Investment, Indebtedness or Liens of such Subsidiary existing at such time and (ii) a return on any Investment by the Borrower in Unrestricted Subsidiaries pursuant to the preceding sentence in an amount equal to the Fair Market Value at the date of such designation of the Borrower’s or its Subsidiary’s (as applicable) Investment in such Subsidiary.

(b) If, at any time, a Restricted Subsidiary would fail to meet the requirements set forth in the definition of “Qualified Restricted Subsidiary”, it will thereafter cease to be a Qualified Restricted Subsidiary for purposes of this Agreement and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary that is not a Qualified Restricted Subsidiary as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 6.01 the Borrower will be in default of such covenant. The Chief Executive Officer or Chief Financial Officer of the Borrower may at any time designate any Restricted Subsidiary not to be a Qualified Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by such Restricted Subsidiary of any outstanding Indebtedness of such Restricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section 6.01 and (2) no Default or Event of Default would be in existence upon or following such designation. In the event (x) a Restricted Subsidiary fails to meet the requirements to be a Qualified Restricted Subsidiary or (y) the Chief Executive Officer or Chief Financial Officer designates a Qualified Restricted Subsidiary not to be a Restricted Subsidiary, then all Investments in such Subsidiary since the Effective Date shall be deemed to be an incurrence under Section 6.04(xv) and to consequently reduce amounts available under Section 5.15(a)(iv), the proviso to Section 6.04(i) and Section 6.04(xv). The Borrower shall deliver to the Administrative Agent a certificate of a Financial Officer setting forth any such designation as a condition precedent to such designation.

(c) Except to the extent restricted pursuant to any Permitted Payment Restrictions, the Borrower shall, and shall cause each Restricted Subsidiary to, cause each Qualified Restricted Subsidiary to declare and pay regular monthly, quarterly, semiannual or annual dividends or distributions to the holders of its Equity Interests in an amount equal to substantially all of the available cash flow of such Qualified Restricted Subsidiary for such period as determined in good faith by the Board of Directors of such Qualified Restricted Subsidiary, subject to fiduciary duties applicable to such Board of Directors and such ordinary and customary reserves and other amounts as, in the good faith judgment of such individuals, may be necessary so that the business of such Qualified Restricted Subsidiary may be properly and advantageously conducted at all times, including amounts for operations, capital expenditures and debt service of such Qualified Restricted Subsidiary.

SECTION 5.16. Post Closing Matters. Borrower shall use its commercially reasonable efforts to (a) deliver within 10 Business Days after the Closing Date (unless waived or extended in the Collateral Agent’s reasonable discretion) that certain promissory note from NorthStar Surgical Center, L.P. to ARC Financial Services Corporation, dated July 15, 2005, accompanied by duly executed instruments of transfer or assignment in blank and (b)(i) order the reports required by Section 4.01(f) for searches conducted with respect to (1) Davidson County, Tennessee and (2) the United States District Court for the Middle District of Tennessee) within 10 Business Days after the Closing Date (unless waived or extended in the Collateral Agent’s sole discretion) and thereafter use commercially reasonable efforts to obtain such reports, (ii) cause such reports to be delivered to the Collateral Agent promptly upon receipt thereof (unless waived or extended in the Collateral Agent’s reasonable discretion) and (iii) within 30 days of the receipt of such reports, cause any Liens (other than Liens permitted by Section 6.02 or other Liens permitted by the Collateral Agent in its reasonable discretion) disclosed in such results to be discharged.

(l) an ERISA Event shall have occurred that, in the opinion of the Required Lenders, when taken together with all other ERISA Events that have occurred, could reasonably be expected to result in liability of the Borrower and the Restricted Subsidiaries in an aggregate amount exceeding $10,000,000 for all periods;

(m) any Lien purported to be created under any Security Document shall cease to be a valid and perfected Lien on any material portion of the Collateral with the priority required by the applicable Security Document, except as a result of the sale or other disposition of the applicable Collateral in a transaction permitted under the Loan Documents or as otherwise expressly permitted hereunder;

SECTION 7.02. Borrower’s Right to Cure.

(a) Notwithstanding anything to the contrary contained in Section 7.01, in the event that the Borrower fails to comply with the requirement of the Financial Performance Covenant, until the expiration of the tenth day subsequent to the date on which financial statements with respect to the fiscal period for which the Financial Performance Covenant is being measured are required to be delivered pursuant to Section 5.01, Holdings shall have the right to issue Qualified Equity Interests (the “Cure Right”), and upon the receipt by the Borrower of cash (such amount of cash being referred to as the “Cure Amount”) pursuant to the exercise by Holdings of such Cure Right, the Financial Performance Covenant shall be recalculated giving effect to the following pro forma adjustments:

(i) Consolidated EBITDA shall be increased, solely for the purpose of determining the existence of a Default or Event of Default under the Financial Performance Covenant with respect to any period of four consecutive fiscal quarters that includes the fiscal quarter for which the Cure Right was exercised and not for any other purpose under this Agreement, by an amount equal to the Cure Amount; and

(ii) if, after giving effect to the foregoing recalculations, the Borrower shall then be in compliance with the requirements of the Financial Performance Covenant (including for purposes of Section 4.02), the Borrower shall be deemed to have satisfied the requirements of the Financial Performance Covenant as of the relevant date of determination with the same effect as though there had been no failure to comply therewith at such date, and the applicable breach or default of the Financial Performance Covenant that had occurred shall be deemed cured for the purposes of this Agreement.

(b) Notwithstanding anything herein to the contrary, (a) in each four fiscal quarter period there shall be a period of at least two fiscal quarters in which no Cure Right is made, (b) all Cure Amounts shall be disregarded for purposes of determining any items in this Agreement (including basket sizes) dependent upon equity contributions or offerings and (c) the Cure Amount shall be no greater than the amount required to cause Borrower to be in compliance with the Financial Performance Covenant.

SECTION 7.03. Exclusion of Immaterial Subsidiaries. Solely for the purposes of determining whether a Default has occurred under Section 7.01(h) or (i), any reference in any such clause to any Restricted Subsidiary shall be deemed not to include any Restricted Subsidiary affected by any event or circumstance referred to in any such clause that did not, as of the last day of the fiscal quarter of the Borrower most recently ended, have assets with a value in excess of 5% of the consolidated total assets of the Borrower and the Restricted Subsidiaries or 5% of the total revenues of the Borrower and the Restricted Subsidiaries as of such date; provided that if it is necessary to exclude more than one Restricted Subsidiary from Section 7.01(h) or (i) pursuant to this Section 7.03 in order to avoid an Event of Default thereunder, all excluded Restricted Subsidiaries shall be considered to be a single consolidated Restricted Subsidiary for purposes of determining whether the condition specified above is satisfied.

ARTICLE VIII

The Agents

SECTION 8.01. The Agents. Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms of the Loan Documents, together with such actions and powers as are reasonably incidental thereto. For purposes of this Article VIII, all references to the Administrative Agent shall be deemed to be references to both the Administrative Agent and the Collateral Agent.

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

The Administrative Agent shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated by the Loan Documents that the Administrative Agent is required to exercise in writing as directed by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 2.05(j) and Section 9.02), and (c) except as expressly set forth in the Loan Documents, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to Holdings, the Borrower or any of the Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 2.05(j) or Section 9.02) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by Holdings, the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

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

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

Each of the Lenders, the Issuing Bank and the Loan Parties agree that the Administrative Agent may, subject to Section 9.01(b), but shall not be obligated to, make the Approved Electronic Communications available to the Lenders and the Issuing Bank by posting such Approved Electronic Communications on IntraLinks™ or a substantially similar secure electronic platform chosen by the Administrative Agent to be its electronic transmission system (the “Approved Electronic Platform”) and each of the Loan Parties agrees to make the Approved Electronic Communications available to the Administrative Agent in an acceptable soft copy or electronic format.

Although the Approved Electronic Platform and its primary web portal are secured with generally-applicable security procedures and policies implemented or modified by the Administrative Agent from time to time (including, as of the Effective Date, a dual firewall and a User ID/Password Authorization System) and the Approved Electronic Platform is secured through a single-user-per-deal authorization method whereby each user may access the Approved Electronic Platform only on a deal-by-deal basis, each of the Lenders and the Issuing Bank and the Loan Parties acknowledge and agree that the distribution of material through an electronic medium is not necessarily secure and that there are confidentiality and other risks associated with such distribution. In consideration for the convenience and other benefits afforded by such distribution and for the other consideration provided hereunder, the receipt and sufficiency of which is hereby acknowledged, each of the Lenders, the Loan Parties and the Issuing Bank hereby approve distribution of the Approved Electronic Communications through the Approved Electronic Platform and understands and assumes the risks of such distribution.

The Approved Electronic Communications and the Approved Electronic Platform are provided “as is” and “as available”. None of the Administrative Agent or any of its Affiliates or any of their respective officers, directors, employees, agents, advisors or representatives (the “Agent Affiliates”) warrant the accuracy, adequacy or completeness of the Approved Electronic Communications and the Approved Electronic Platform and each expressly disclaims liability for errors or omissions in the Approved Electronic Communications and the Approved Electronic Platform. No warranty of any kind, express, implied or statutory (including, without limitation, any warranty of merchantability, fitness for a particular purpose, noninfringement of third party rights or freedom from viruses or other code defects) is made by the Agent Affiliates in connection with the Approved Electronic Communications or the Approved Electronic Platform.

Each of the Lenders, the Issuing Bank, and the Loan Parties agrees that the Administrative Agent may, but (except as may be required by applicable law) shall not be obligated to, store the Approved Electronic Communications on the Approved Electronic Platform in accordance with the Administrative Agent’s generally-applicable document retention procedures and policies.

The Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrower. Upon any such resignation, the Required Lenders shall have the right, with the consent of the Borrower, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders

and the Issuing Bank, appoint a successor Administrative Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its subagents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or related agreement or any document furnished hereunder or thereunder. The Lenders identified in this Agreement as the Syndication Agent and the Documentation Agents shall not have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders. Without limiting the foregoing, neither the Syndication Agent nor the Documentation Agents shall have or be deemed to have a fiduciary relationship with any Lender.

communications to it hereunder by electronic communications pursuant to procedures approved by it, provided that approval of such procedures may be limited to particular notices or communications. All such notices and other communications (i) sent to an e-mail address shall be deemed received upon the sender’s receipt of an acknowledgement from the intended recipient (such as by the “return receipt requested” function, as available, return e-mail or other written acknowledgement); provided that if not given during the normal business hours of the recipient, such notice or communication shall be deemed to have been given at the opening of business on the next Business Day for the recipient, and (ii) posted to an Internet or intranet website shall be deemed received upon the deemed receipt by the intended recipient at its e-mail address as described in the foregoing clause (i) of any required notification that such notice or communication is available and identifying the website address therefor.

SECTION 9.02. Waivers; Amendments.

(a) No failure or delay by the Administrative Agent, the Issuing Bank, the Collateral Agent, the Swingline Lender or any Lender in exercising any right or power hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Bank, the Collateral Agent, the Swingline Lender and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of any Loan Document or consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be permitted by Section 9.02(b), and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any Lender, the Collateral Agent, the Swingline Lender or the Issuing Bank may have had notice or knowledge of such Default at the time.

(b) Except as provided in Section 2.20 with respect to an Incremental Facility Amendment (or to give effect to any restatement of this Agreement, the substantive terms of which are otherwise permitted hereby), neither this Agreement nor any other Loan Document nor any provision hereof or thereof may be waived, amended or modified except, in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by Holdings, the Borrower and the Required Lenders or, in the case of any other Loan Document, pursuant to an agreement or agreements in writing entered into by the Administrative Agent and the Loan Party or Loan Parties that are parties thereto (and, if party thereto, the Collateral Agent), in each case with the consent of the Required Lenders; provided that no such agreement shall

(i) increase the Commitment of any Lender without the written consent of such Lender,

(ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected (other than any waiver of default interest payable pursuant to Section 2.13(c)) thereby (it being understood that a change to the definition of the Leverage Ratio that could have the effect of reducing such interest or fees upon certain conditions shall not be deemed in and of itself to reduce such interest or fees),

(iii) postpone the final maturity of any Loan, or any scheduled date of payment of the principal amount of any Term Loan under Section 2.10, the required date of reimbursement of any LC Disbursement, or any date for the payment of any interest or fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby,

(iv) change Section 2.18(b) or (c) in a manner that would alter the prorata sharing of payments required thereby, without the written consent of each Lender,

(v) change any of the provisions of this Section 9.02 or the percentage set forth in the definition of “Required Lenders” or any other provision of any Loan Document specifying the number or percentage of Lenders (or Lenders of any Class) required to waive, amend or modify any rights thereunder or make any determination or grant any consent thereunder, without the written consent of each Lender (or each Lender of such Class, as applicable),

(vi) release Holdings or substantially all Subsidiary Loan Parties from their Guarantee under the Collateral Agreement (except as provided in Section 9.15 or in the Collateral Agreement) or limit liability of Holdings or of substantially all Subsidiary Loan Parties in respect of such Guarantee, without the written consent of each Lender,

(vii) release all or substantially all the Collateral from the Liens of the Security Documents (except as provided in Section 9.15 or in the Collateral Agreement), without the written consent of each Lender,

(viii) change any provisions of any Loan Document in a manner that by its terms adversely affects the rights in respect of payments due to Lenders holding Loans of any Class differently than those holding Loans of any other Class, without the written consent of Lenders holding a majority in interest of the outstanding Loans and unused Commitments of each adversely affected Class, or

(ix) modify the definition of “Interest Period” to allow periods of more than twelve months without regard to the agreement of all participating Lenders, without the written consent of each Lender;

provided, further, that (A) no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, the Issuing Bank or the Swingline Lender without the prior written consent of the Administrative Agent, the Issuing Bank or the Swingline Lender, as applicable, (B) any waiver, amendment or modification of this Agreement that by its terms affects the rights or duties under this Agreement of the Revolving Lenders (but not the Term Lenders), the Tranche B Lenders (but not the Tranche A Lenders or Revolving Lenders) , the Tranche A Lenders (but not the Tranche B Lenders or Revolving Lenders), or the Term Lenders (but not the Revolving Lenders) may be effected by an agreement or agreements in writing entered into by Holdings, the Borrower and requisite percentage in interest of the affected Class(es) of Lenders that would be required to consent thereto under this Section 9.02(b) if

such Class(es) of Lenders were the only Class(es) of Lenders hereunder at the time and (C) if the Administrative Agent and the Borrower shall have jointly identified an obvious error or any error or omission of a technical or immaterial nature in any provision of the Loan Documents, then the Administrative Agent and the Borrower shall be permitted to amend such provision and such amendment shall become effective without any further action or consent of any other party to any Loan Document if the same is not objected to in writing by the Required Lenders within five (5) Business Days notice thereof. In connection with any proposed amendment, modification, waiver or termination (a “Proposed Change”) requiring the consent of all affected Lenders, if the consent of the Required Lenders (and, to the extent any Proposed Change requires the consent of Lenders holding Loans of any Class pursuant to Section 9.02(b)(viii), the consent of not less than a majority in interest of the outstanding Loans and unused Commitments of such Class) to such Proposed Change is obtained, but the consent to such Proposed Change of other Lenders whose consent is required is not obtained (any such Lender whose consent is not obtained as described in this Section 9.02(b) being referred to as a “Non-Consenting Lender”), then, so long as the Lender that is acting as the Administrative Agent is not a Non-Consenting Lender, at the Borrower’s request, any assignee that is acceptable to the Administrative Agent shall have the right, with the Administrative Agent’s consent, to purchase from such Non-Consenting Lender, and such Non-Consenting Lender agrees that it shall, upon the Borrower’s request, sell and assign to such assignee, at no expense to such Non-Consenting Lender, all the Commitments, Term Loans and Revolving Exposure of such Non-Consenting Lender for an amount equal to the principal balance of all Term Loans and Revolving Loans (and funded participations in Swingline Loans and unreimbursed LC Disbursements) held by such Non-Consenting Lender and all accrued interest and fees with respect thereto through the date of sale (including amounts under Sections 2.15, 2.16 and 2.17) so long as such principal balance of all other Non-Consenting Lenders is similarly purchased, such purchase and sale to be consummated pursuant to an executed Assignment and Assumption in accordance with Section 9.04(b) (which Assignment and Assumption need not be signed by such Non-Consenting Lender).

(c) Notwithstanding the provisions of Section 9.02(b), this Agreement may be amended (or amended and restated) with the written consent of the Required Lenders, the Administrative Agent, Holdings and the Borrower (i) to add one or more additional credit facilities to this Agreement and to permit the extensions of credit from time to time thereunder and the accrued interest and fees in respect thereof to share ratably in the benefits of this Agreement and the other Loan Documents with the Term Loans and the Revolving Loans and the accrued interest and fees in respect thereof, and (ii) to include appropriately the Lenders holding such credit facilities in any determination of the Required Lenders. In addition, this Agreement may be amended with the written consent of the Administrative Agent, Holdings, the Borrower and the Lenders providing the relevant Replacement Term Loans (as defined below) to permit the refinancing of all outstanding Tranche A Term Loans and Tranche B Term Loans (the “Refinanced Term Loans”) and, if applicable, related outstanding commitments, with a replacement term loan tranche or tranches hereunder (the “Replacement Term Loans”); provided that (i) the aggregate principal amount of such Replacement Term Loans shall not exceed the aggregate principal amount of such Refinanced Term Loans, (ii) the weighted average Applicable Rate for such Replacement Term Loans shall not be higher than the weighted average Applicable Rate for such Refinanced Term Loans, (iii) the weighted average life to maturity of such Replacement Term Loans shall not be shorter than the weighted average life to maturity of such Refinanced Term Loans at the time of such refinancing (except to the extent of nominal amortization for periods where amortization has been eliminated as a result of prepayment of the Refinanced Term Loans) and (iv) all other terms applicable to such Replacement Term Loans shall be substantially identical to, or less favorable to the Lenders providing such Replacement Term Loans than, those applicable to such Refinanced Term Loans, except to the extent necessary to provide for covenants and other terms applicable to any period after the latest final maturity of the Refinanced Term Loans in effect immediately prior to such refinancing.

SECTION 9.03. Expenses; Indemnity; Damage Waiver.

(a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Agents and their respective Affiliates, including the reasonable fees, charges and disbursements of counsel for the Agents, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of the Loan Documents or any amendments, modifications or waivers of the provisions thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iii) all out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, the Issuing Bank or any Lender, in connection with the enforcement of its rights in connection with the Loan Documents, including its rights under this Section 9.03, or in connection with the Loans made or Letters of Credit issued hereunder, including all such reasonable out-of-pocket expenses incurred during any workout or restructuring in respect of such Loans or Letters of Credit.

(b) The Borrower shall indemnify the Administrative Agent, each Agent, the Issuing Bank and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”), and hold each Indemnitee harmless, from and against 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 any Loan Document or any other agreement or instrument contemplated hereby, the performance by the parties to the Loan Documents of their respective obligations thereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by the Issuing Bank 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 of Hazardous Materials on, at, under or emanating from any Mortgaged Property or any other property currently or formerly owned or operated by the Borrower or any of its Subsidiaries, or any actual or alleged Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto or such litigation, claim, investigation or proceeding is brought by a third party or by the Borrower or its Affiliates, provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (y) are finally judicially determined by a non-appealable judgment of a court of competent jurisdiction to have resulted from the gross negligence, bad faith or willful misconduct of, or breach of the Loan Documents by, such Indemnitee or (z) result from the presence or Release of Hazardous Materials or an Environmental Liability to the extent such presence, Release or Environmental Liability is caused by such Indemnitee or first occurs or first exists after completion of the foreclosure upon the Collateral, granting a deed-in-lieu of foreclosure with respect to the Collateral or similar transfer of title or possession of the Collateral.

(c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent, each Agent, the Issuing Bank or the Swingline Lender under Sections 9.03(a) or (b), each Lender severally agrees to pay to the Administrative Agent, such Agent, the Issuing Bank or the Swingline Lender, as applicable, such Lender’s pro rata share (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 applicable, was incurred by or asserted against the Administrative Agent, the Issuing Bank or the Swingline Lender in its capacity as such. For purposes hereof, a Lender’s “pro rata share” shall be determined based

upon its share of the aggregate Revolving Exposures, outstanding Term Loans and unused Commitments at the time.

(d) To the extent permitted by applicable law, neither Holdings nor the Borrower shall assert, and each hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

(e) All amounts due under this Section 9.03 shall be payable not later than ten Business Days after written demand therefor.

SECTION 9.04. Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) except in connection with any transaction permitted in accordance with Section 6.03(a)(i) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section 9.04. Nothing in this Agreement, express 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 Bank that issues any Letter of Credit), Participants (to the extent provided in Section 9.04(c)) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank 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 clause (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld or delayed) of:

(1) 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 (as defined below) or, if an Event of Default under Section 7.01(a), (b), (h), (i) or (j) has occurred and is continuing, any other assignee;

(2) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment of all or any portion of a Term Loan to a Lender, an Affiliate of a Lender or an Approved Fund; and

(3) the Issuing Bank, provided that no consent of the Issuing Bank shall be required for an assignment of all or any portion of a Term Loan.

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

(1) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans of any Class, the amount of the Commitment or Loans of the assigning Lender subject to each such

assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 or, in the case of a Term Loan, $1,000,000, unless each of the Borrower and the Administrative Agent otherwise consents; provided that no such consent of the Borrower shall be required (x) for an assignment by a Lender to an Approved Fund of a Lender or (y) if an Event of Default has occurred and is continuing, and that contemporaneous assignments to Approved Funds related to the same Lender shall be aggregated when calculating such minimum assignment amounts;

(2) 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 assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of one Class of Commitments or Loans;

(3) 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

(4) the assignee, if it is not already a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

For purposes of this Section 9.04(b):

“Approved Fund” means (a) a CLO and (b) with respect to any Lender that is a fund which invests in bank loans and similar extensions of credit, any other fund that invests in bank loans and similar extensions of credit and is managed or advised by the same investment advisor as such Lender or by an Affiliate of such investment advisor.

“CLO” means any entity (whether a corporation, partnership, trust or otherwise) that is engaged in making, purchasing, holding or otherwise investing in bank loans and similar extensions of credit in the ordinary course and is administered or managed by a Lender or an Affiliate of such Lender.

(iii) Subject to acceptance and recording thereof pursuant to Section 9.04(b)(iv), from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.15, 2.16, 2.17 and 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 9.04(c).

(iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Issuing Banks and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder

for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the Issuing Banks and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in Section 9.04(b) and any written consent to such assignment required by Section 9.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c) (i) Any Lender may, without the consent of the Borrower, the Administrative Agent, the Issuing Banks or the Swingline Lender, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it), provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement, provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects such Participant. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of Borrower, maintain a register on which it enters the name and address of each Participant and the principal and interest amounts of each Participant’s interest in the Loans held by it (the “Participant Register”). The entries in the Participant Register shall be conclusive, absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such Loan or other obligation hereunder for all purposes of this Agreement notwithstanding any notice to the contrary. Subject to Section 9.04(c)(ii), the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.15, 2.16 and 2.17 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 9.04(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.18(c) as though it were a Lender.

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

(iii) Any Lender may at any time pledge, assign or grant a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge,

100

assignment or grant to secure obligations to a Federal Reserve Bank, and this Section 9.04 shall not apply to any such pledge, assignment or grant of a security interest, provided that no such pledge, assignment or grant of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledge or assignee for such Lender as a party hereto.

SECTION 9.05. Survival. All covenants, agreements, representations and warranties made by the Loan Parties in the Loan Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall have independent significance and be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of the Loan Documents 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 Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Sections 2.15, 2.16, 2.17 and 9.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof.

SECTION 9.06. 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, the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other 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 facsimile or electronic transmission shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 9.07. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 9.08. Right of Setoff. If any Event of Default under Section 7.01(a) or (b) 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 then due and owing held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement. The applicable Lender shall notify the Borrower and the Administrative Agent of such setoff or application, provided that any failure to give or any delay in giving such notice shall not affect

101

the validity of any such setoff or application under this Section 9.08. The rights of each Lender under this Section 9.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

SECTION 9.09. Governing Law; Jurisdiction; Consent to Service of Process.

(a) This Agreement shall be construed in accordance with and governed by the law of the State of New York.

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

(c) Each of Holdings and the Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in Section 9.09(b). Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement or any other Loan Document will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 9.10. 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, ANY OTHER LOAN DOCUMENT 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 9.10.

102

SECTION 9.11. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

SECTION 9.12. Confidentiality. Each of the Administrative Agent, the Issuing Banks and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, trustees, 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 or self-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 any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section 9.12, to (i) any assignee or pledgee of or Participant in, or any prospective assignee or pledgee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section 9.12 or (ii) becomes available to the Administrative Agent, any Issuing Bank or any Lender on a nonconfidential basis from a source other than Holdings or the Borrower or any of their subsidiaries, provided that such source is not actually known by such disclosing party to be bound by an agreement containing provisions substantially the same as those contained in this Section 9.12. For the purposes of this Section 9.12, the term “Information” means all information received from Holdings or the Borrower relating to Holdings or the Borrower or its business, other than any such information that is available to the Administrative Agent, any Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by Holdings or the Borrower. Any Person required to maintain the confidentiality of Information as provided in this Section 9.12 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

SECTION 9.13. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts that are treated as interest on such Loan under applicable law (collectively, the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) that may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section 9.13 shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

SECTION 9.14. USA Patriot Act. Each Lender, each Agent and the Issuing Bank hereby notifies the Borrower that pursuant to the requirements of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001, Public Law 107-56 (the “USA 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 Person to identify the Borrower in accordance with the USA Patriot Act.
