(c) The Administrative Agent, on behalf of Borrower, shall maintain the Register pursuant to Section 9.6(d), and a subaccount therein for each Lender, in which shall be recorded (i) the amount of each Loan made hereunder and any Note evidencing such Loan, (ii) the amount of any principal or interest due and payable or to become due and payable from Borrower to each Lender hereunder and (iii) both the amount of any sum received by the Administrative Agent hereunder from Borrower and each Lender’s share thereof.

(d) The entries made in the Register and the accounts of each Lender maintained pursuant to this Section 2.4 shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations of Borrower therein recorded; provided, however, that the failure of any Lender or the Administrative Agent to maintain the Register or any such account, or any error therein, shall not in any manner affect the obligation of Borrower to repay (with applicable interest) the Loans made to Borrower by such Lender in accordance with the terms of this Agreement.

(e) Borrower agrees that, upon the request to the Administrative Agent by any Lender, Borrower will promptly execute and deliver to such Lender a promissory note of Borrower evidencing any Loans of such Lender, substantially in the form of Exhibit G (a “Note”), with appropriate insertions as to date and principal amount; provided that delivery of Notes shall not be a condition precedent to the occurrence of the Closing Date or the making of the Loans on any Borrowing Date.

2.5 Fees.

(a) On the Closing Date, Borrower shall pay the Administrative Agent for the account of each Lender a fee equal to 1.0% of the aggregate principal amount of the Loan made by such Lender.

(b) On the first anniversary of the Closing Date, Borrower shall pay the Administrative Agent for the account of the Lenders as of such first anniversary a fee equal to 0.50% of the aggregate principal amount of the Loans made by the Lenders on the Closing Date, which fee shall be fully earned on the Closing Date.

(c) Borrower shall pay to the Administrative Agent for its own account an annual nonrefundable administration fee equal to $50,000, such fee to be paid in advance on the Closing Date and thereafter on each anniversary of the Closing Date (other than the Maturity Date) or, if any such date is not a Business Day, on the first Business Day thereafter.

(d) Borrower agrees to pay to the Administrative Agent the fees in the amounts and on the dates from time to time agreed to in writing by Borrower and the Administrative Agent.

2.6 Optional Prepayments.

(a) Subject to the concurrent payment of the Applicable Premium, Borrower may, upon at least three Business Days’ prior notice to the Administrative Agent stating the Prepayment Date and aggregate principal amount of the prepayment, prepay on any date the outstanding principal amount of the Loans, in whole or in part, at Borrower’s option at 100% of the principal amount thereof, together with accrued interest through the Prepayment Date on the principal amount prepaid, in accordance with the provisions of this Agreement.

(b) For purposes hereof, the “Applicable Premium” shall be a cash amount equal to the percentages of principal amount of the Loans being prepaid set forth below:


If prepaid on or prior to December 31, 2008	1.0	%
If prepaid at any time after December 31, 2008	0.0	%

(c) Each partial prepayment shall be in an aggregate amount not less than $1,000,000 or integral multiples of $100,000 in excess thereof, and any such prepayment must be accompanied by payment of Agent’s and each Lender’s reasonable out-of-pocket expenses and payment of any LIBOR funding breakage costs in accordance with Section 2.12.

(e) Any optional prepayment under this Section 2.6 shall be applied to the Loans as set forth in Section 2.9 below.

2.7 Mandatory Prepayments.

(a) Unless the Required Lenders shall otherwise agree, if any Capital Stock shall be issued (excluding any Permitted Equity Financing), or any Indebtedness (excluding any Permitted Indebtedness) incurred, by any Loan Party or any Person shall make any contribution to the capital of any Loan Party (excluding any Permitted Equity Financing, contributions by Holdings to the capital of Borrower, or by Borrower to the capital of any Wholly Owned Subsidiary Guarantor), then on the date of such issuance, incurrence or capital contribution, Borrower shall prepay the principal amount of the Loans in an amount equal to the amount of the Net Cash Proceeds of such issuance, incurrence or capital contribution. The provisions of this Section 2.7(a) do not constitute a consent to the issuance of any Capital Stock by any Person whose Capital Stock is pledged pursuant to any Security Document, or a consent to the incurrence of any Indebtedness or the making of any capital contribution by any Loan Party.

(b) Unless the Required Lenders shall otherwise agree, if on any date any Loan Party shall receive a Purchase Price Refund or Net Cash Proceeds from any Asset Sale or Recovery Event then, on the date of receipt by such Person of such Net Cash Proceeds or such Purchase Price Refund, Borrower shall prepay the principal amount of the Loans in an amount equal to the amount of such Net Cash Proceeds or such Purchase Price Refund; provided, however, that in the case of any Net Cash Proceeds constituting the Reinvestment Deferred Amount with respect to a Reinvestment Event, Borrower shall prepay the Loans in an amount equal to the Reinvestment Prepayment Amount applicable to such Reinvestment Event, if any, on the Reinvestment Prepayment Date with respect to such Reinvestment Event; provided further that the aggregate Net Cash Proceeds of Reinvestment Events that may be

specified as Reinvestment Deferred Amounts in one or more Reinvestment Notices shall not exceed $250,000 in the case of any Reinvestment Event and $500,000 in the aggregate in the case of all Reinvestment Events. The provisions of this Section do not constitute a consent to the consummation of any Disposition not permitted by Section 6.5.

(c) If on any date, a Collateral Value Deficiency exists, Borrower shall immediately (and in any event no later than the date five Business Days after such date), and without the necessity of demand by the Administrative Agent, prepay the principal amount of the Loans by an amount equal to the amount of such Reserve Value Deficiency.

(d) Not later than 75 days after the last day of each fiscal year beginning with fiscal year 2008, Borrower shall prepay the principal amount of the Loans in an amount equal to 75% of Excess Cash Flow for such fiscal year;

(e) Upon the occurrence of a Change of Control, the Required Lenders, at their sole discretion, may require Borrower to immediately prepay the outstanding principal amount of the Loans (after considering any prepayments by Borrower pursuant to Section 2.6), together with all other amounts owing under this Agreement or any Loan Document including any fees and expenses earned or then due and payable under any Loan Document.

(f) Each prepayment of the Loans pursuant to this Section 2.7 shall be applied in accordance with Section 2.9 below and shall be accompanied by payment of accrued interest to the Prepayment Date on the principal amount prepaid. Each prepayment of the Loans pursuant to Section 2.7(a), (b), (c) or (e) shall include a concurrent payment of the Applicable Premium.

2.8 Interest Rates, Payment Dates and Computation of Interest and Fees.

(a) Each Loan shall bear interest for each day on which it is outstanding at the Interest Rate.

(b) (i) If all or a portion of the principal amount of any Loan shall not be paid when due (whether at the stated maturity, by acceleration or otherwise) or there shall occur and be continuing any other Event of Default, all outstanding Loans (whether or not overdue) (to the extent legally permitted) shall bear interest at a rate per annum that is equal to the Interest Rate plus 2.0% the (“Default Rate”), from the date of such nonpayment of principal or occurrence of such Event of Default, respectively, until such amount of principal is paid in full (after as well as before judgment) or until such Event of Default is no longer continuing, respectively, and (ii) if all or a portion of any interest payable on any Loan or any fee or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum equal to the Default Rate, in each case, with respect to clauses (i) and (ii) above, from the date of such non payment until such amount is paid in full (after as well as before judgment).

(c) Subject to Section 2.7(f) and Section 2.9(h), interest shall be payable in arrears on each Interest Payment Date, provided that interest accruing pursuant to Section 2.8(b) shall be payable from time to time on demand.

(d) Interest, fees and commissions payable pursuant hereto shall be calculated on the basis of a year of 360 days.

2.9 Application of Payments.

(a) The borrowing by Borrower from the Lenders hereunder, any reduction of the Commitments of the Lenders and, subject to Section 2.9(c), each payment by Borrower on account of any commitment fee, shall be made pro rata according to the Aggregate Exposure Percentages of the relevant Lenders. Each payment (including any prepayment) in respect of principal or interest in respect of any Loans and each payment in respect of fees or expenses payable hereunder shall be applied to the amounts of such obligations owing to the Lenders pro rata according to the respective amounts then due and owing to the Lenders. Amounts prepaid on account of the Loans may not be reborrowed.

(b) So long as no Event of Default shall have occurred and be continuing all payments and any other amounts received by the Administrative Agent from or for the benefit of Borrower shall be applied: (i) first, to pay all Obligations then due and payable and (ii) second, as Borrower so designates.

(c) After the occurrence and during the continuance of any Event of Default, Borrower hereby irrevocably waives the right to direct the application of any and all payments in respect of the Obligations and any proceeds of Collateral, and agrees that the Administrative Agent may, and shall upon either (A) the written direction of the Required Lenders or (B) the acceleration of the Obligations pursuant to Section 7.1, apply all payments in respect of any Obligations and all proceeds of Collateral in the following order:

(i) first, to the payment or reimbursement of the Administrative Agent for all costs, expenses, disbursements and losses incurred by the Administrative Agent and which any Loan Party is required to pay or reimburse pursuant to the Loan Documents;

(ii) second, to the payment or reimbursement of the Lenders for all costs, expenses, disbursements and losses incurred by such Persons and which any Loan Party is required to pay or reimburse pursuant to the Loan Documents;

(iii) third, to the payment of interest on the Loans which is then due;

(iv) fourth, to the payment of principal of the Loans which is then due;

(v) fifth, to the payment or prepayment to the Lenders of all other Obligations; and

(vi) sixth, to whomsoever shall be legally entitled thereto.

(d) If any Lender owes payments to the Administrative Agent hereunder, any amounts otherwise distributable under this Section 2.9 to such Lender shall be deemed to belong to the Administrative Agent to the extent of such unpaid payments, and the Administrative Agent shall apply such amounts to make such unpaid payments rather than distribute such amounts to such Lender. All distributions of amounts described in paragraphs second and fifth above shall be made by the Administrative Agent to each Lender on a pro rata basis determined by the amount such Obligations owed to such Lender represents of the aggregate amount of all such Obligations.

(e) All payments (including prepayments) to be made by Borrower hereunder, whether on account of principal, interest, premium, fees or otherwise, shall be made without setoff or counterclaim and shall be made prior to 12:00 Noon, New York City time, on the due date thereof to the Administrative Agent, for the account of the relevant Lenders, at the Payment Office, in Dollars and in immediately available funds. Any payment made by Borrower after 12:00 Noon, New York City time, on any Business Day shall be deemed to have been made on the next following Business Day. The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received. If any payment hereunder becomes due and payable on a day other than a Business Day, such

payment shall be extended to the next succeeding Business Day. In the case of any extension of any payment of principal pursuant to the preceding sentence, interest thereon shall be payable at the then-applicable rate during such extension.

(f) Unless the Administrative Agent shall have been notified in writing by any Lender prior to the borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to Borrower a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on any Borrowing Date, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon at a rate equal to the average Federal Funds Effective Rate for the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this Section 2.9(f) shall be conclusive in the absence of manifest error. If such Lender’s share of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days after such Borrowing Date, the Administrative Agent shall also be entitled to recover such amount with interest thereon at the Interest Rate, on demand, from Borrower.

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

(h) Each payment of the Loans shall be accompanied by accrued interest to the date of such payment on the amount paid.

2.10 Requirements of Law.

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

(i) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, any Application or any LIBOR Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by Section 2.11 and changes in the rate of tax on the overall net income of such Lender);

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

(iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender, by an amount which such Lender deems to be material, of making, continuing or maintaining Loans bearing interest by reference to the LIBOR Rate, or to reduce any amount receivable hereunder in respect thereof, then, in any such case, Borrower shall promptly pay such Lender, upon its demand, any additional amounts necessary to compensate such Lender on an after-tax basis for such increased cost or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this Section 2.10, it shall promptly notify Borrower (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled.

(b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy, reserve requirements or similar requirements generally acceptable to lending institutions or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy, reserve requirements or similar requirements (whether or not having the force of law) from any Governmental Authority made subsequent to the Closing Date shall have the effect of reducing the rate of return on such Lender’s or such corporation’s capital as a consequence of its obligations hereunder to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or such corporation’s policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to Borrower (with a copy to the Administrative Agent) of a written request therefor, Borrower shall promptly pay to such Lender such additional amount or amounts as will compensate such Lender or such corporation for such reduction on an after-tax basis.

(c) A certificate as to any additional amounts payable pursuant to this Section submitted by any Lender to Borrower (with a copy to the Administrative Agent) shall be conclusive in the absence of manifest error. The obligations of Borrower pursuant to this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

(d) Notwithstanding anything to the contrary contained herein, if the introduction of or any change in any law or regulation (or any change in the interpretation thereof) after the Closing Date shall make it unlawful, or any central bank or other Governmental Authority shall assert after the Closing Date that it is unlawful, for any Lender to agree to make or to make or to continue to fund or maintain any Loan bearing interest by reference to the LIBOR Rate, then, unless that Lender is able to make or to continue to fund or to maintain such Loan at another branch or office of that Lender without, in that Lender’s opinion, adversely affecting it or its Loans or the income obtained therefrom, on notice thereof and demand therefor by such Lender to Borrower through the Administrative Agent, (i) the obligation of such Lender to agree to make or to make or to continue to fund or maintain Loans bearing interest by reference to the LIBOR Rate shall terminate, and (ii) all of such Lender’s Loans shall automatically convert at the end of the then-current LIBOR Period with respect thereto or sooner, if required by such law, regulation or interpretation, into Loans bearing interest with respect to such Lender from and after the date of such conversion at a rate per annum equal to the sum of (x) the Federal Funds Effective Rate in effect from time to time plus 0.50% and (y) the Interest Margin.

2.11 Taxes.

(a) All payments made by any Loan Party under this Agreement or any other Loan Documents shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding net income taxes and franchise taxes (imposed in lieu of net income taxes) imposed on any Agent or any Lender as a result of a present or former connection between such Agent or such

Lender and the jurisdiction of the Governmental Authority imposing such tax or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from such Agent’s or such Lender’s having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any other Loan Document). If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) or any Other Taxes are required to be withheld from any amounts payable to any Agent or any Lender hereunder, the amounts so payable to such Agent or such Lender shall be increased to the extent necessary to yield to such Agent or such Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement; provided, however, that Borrower or any Guarantor shall not be required to increase any such amounts payable to any Agent or any Lender with respect to any Non-Excluded Taxes (i) that are attributable to such Agent’s or such Lender’s failure to comply with the requirements of Sections 2.11(d) or (e) or (ii) that are United States withholding taxes imposed on amounts payable to such Agent or such Lender at the time such Agent or such Lender becomes a party to this Agreement, except to the extent that such Agent’s or such Lender’s assignor (if any) was entitled, at the time of assignment, to receive additional amounts from Borrower with respect to such Non-Excluded Taxes pursuant to this Section 2.11(a). Borrower or the applicable Guarantor shall make any required withholding and pay the full amount withheld to the relevant tax authority or other Governmental Authority in accordance with applicable Requirements of Law.

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

(c) Whenever any Non-Excluded Taxes or Other Taxes are payable by Borrower, as promptly as possible thereafter Borrower shall send to the Administrative Agent for the account of the relevant Agent or Lender, as the case may be, a certified copy of an original official receipt received by Borrower showing payment thereof. If Borrower fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, Borrower shall indemnify the Agents and the Lenders for any incremental taxes, interest or penalties that may become payable by any Agent or any Lender as a result of any such failure. The agreements in this Section 2.11 shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

(d) Each Lender (or Transferee) that is not a citizen or resident of the United States of America, a corporation, partnership or other entity created or organized in or under the laws of the United States of America (or any jurisdiction thereof), or any estate or trust that is subject to federal income taxation regardless of the source of its income (a “Non U.S. Lender”) shall deliver to Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased) two copies of either U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI, or, in the case of a Non U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest” a statement substantially in the form of Exhibit H to the effect that such Lender is eligible for a complete exemption from withholding of U.S. taxes under Section 871(h) or 881(c) of the Code and a Form W-8BEN, or any subsequent versions thereof or successors thereto properly completed and duly executed by such Non U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by Borrower under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non U.S. Lender on or before the date it becomes a party to this Agreement (or, in the case of any Participant, on or before the date such Participant purchases the related participation). In addition, each Non U.S. Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Non U.S. Lender. Each Non-U.S. Lender shall promptly notify Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to Borrower (or any other form of certification adopted by the U.S. taxing authorities for such

purpose). Notwithstanding any other provision of this Section 2.11(d), a Non U.S. Lender shall not be required to deliver any form pursuant to this Section 2.11(d) that such Non U.S. Lender is not legally able to deliver.

(e) A Lender that is entitled to an exemption from or reduction of non-U.S. withholding tax under the law of the jurisdiction in which Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate, provided that such Lender is legally entitled to complete, execute and deliver such documentation and in such Lender’s reasonable judgment such completion, execution or submission would not materially prejudice the legal position of such Lender.

2.12 Indemnity. Borrower agrees promptly to indemnify each Lender for, and to hold each Lender harmless from, any loss or expense that such Lender may sustain or incur as a consequence of (a) the failure to make any prepayment of a Loan after Borrower has given a notice thereof in accordance with the provisions of this Agreement; (b) the repayment of any Loans that are repaid in whole or in part prior to the last day of a LIBOR Period (whether such repayment is made pursuant to any provision of this Agreement or any other Loan Document or occurs as a result of acceleration, mandatory prepayment, by operation of law or otherwise); or (c) a default in payment when due of the principal amount of or interest on any Loan; or (d) a default in making any borrowing of Loans after Borrower has given notice requesting the same in accordance herewith. Such indemnification shall include any loss (excluding loss of margin) or expense arising from the reemployment of funds obtained by it or from fees payable to terminate deposits from which such funds were obtained. For the purpose of calculating amounts payable to a Lender under this Section 2.12, each Lender shall be deemed to have actually funded its relevant Loan through the purchase of a deposit bearing interest at the LIBOR Rate in an amount equal to the amount of that Loan and having a maturity comparable to the LIBOR Period; provided that each Lender may fund each of its Loans in any manner it deems appropriate, and the foregoing assumption shall be utilized only for the calculation of amounts payable under this Section 2.12. A certificate as to any amounts payable pursuant to this Section submitted to Borrower by any Lender shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the repayment of the Loans and all other amounts payable hereunder.

2.13 Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.10 or 2.11(a) with respect to such Lender, it will, if requested by Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans affected by such event with the object of avoiding the consequences of such event; provided that such designation is made on terms that, in the sole judgment of such Lender, cause such Lender and its lending office(s) to suffer no economic, legal or regulatory disadvantage, and provided, further, that nothing in this Section 2.13 shall affect or postpone any of the obligations of Borrower or the rights of any Lender pursuant to Section 2.10 or 2.11(a).

ARTICLE III
REPRESENTATIONS AND WARRANTIES

To induce the Agents and the Lenders to enter into this Agreement and to make the Loans, each of Holdings and Borrower hereby represents and warrants, jointly and severally, to each Agent and each Lender that on the date hereof and on the Closing Date:

3.1 Financial Condition.

(a) The unaudited pro forma consolidated balance sheet of Holdings and its consolidated Subsidiaries as at September 30, 2007 (including the notes thereto) (the “Pro Forma Balance Sheet”), copies of which have heretofore been furnished to the Administrative Agent, has been prepared giving effect (as if such events had occurred on such date) to (i) the Loans to be made on the Closing Date and the use of proceeds thereof and (ii) the payment of fees and expenses in connection with the foregoing. The Pro Forma Balance Sheet has been prepared based on the best information available to Holdings as of the date of delivery thereof, and presents fairly on a pro forma basis the estimated financial position of Holdings and its consolidated Subsidiaries as at September 30, 2007, assuming that the events specified in the preceding sentence had actually occurred at such date.

(b) The audited consolidated balance sheets of Holdings as at December 31, 2005 and December 31, 2006, and the related consolidated statements of income and of cash flows for the fiscal years ended on such dates, reported on by and accompanied by an unqualified report from the Independent Accountant, present fairly the consolidated financial condition of Holdings as at such date, and the consolidated results of its operations and its consolidated cash flows for the respective fiscal years then ended. The unaudited consolidated balance sheet of Holdings as at September 30, 2007, and the related unaudited consolidated statements of income and cash flows for the nine-month period ended on such date, present fairly the consolidated financial condition of Holdings as at such date, and the consolidated results of its operations and its consolidated cash flows for the nine-month period then ended (subject to normal year end audit adjustments). All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved (except as approved by the aforementioned firm of accountants and disclosed therein). No Loan Party has any material Guarantee Obligations, contingent liabilities and liabilities for taxes, or any long term leases or unusual forward or long term commitments, including, any interest rate or foreign currency swap or exchange transaction or other obligation in respect of derivatives, that are not reflected in the most recent financial statements referred to in this paragraph. During the period from October 1, 2007 to and including the date hereof there has been no Disposition by any Loan Party of any material part of its business or Property except as described on Schedule 3.1(b).

3.2 No Change. Except as set forth on Schedule 3.2, since December 31, 2006, there has been no development or event that has had or could reasonably be expected to have a Material Adverse Effect.

3.3 Corporate Existence; Compliance with Law.

(a) Each of the Loan Parties (i) is duly incorporated, organized or formed, as applicable, validly existing and (if relevant) in good standing under the laws of the jurisdiction of its incorporation, organization or formation, as the case may be, (ii) has the corporate, company or partnership power and authority, as applicable, and the legal right, to own and operate its Property, to lease the Property it operates as lessee and to conduct the business in which it is currently engaged, (iii) is duly qualified as a foreign corporation, company or partnership, as applicable, and (if relevant) in good standing under the laws of each jurisdiction where its ownership, lease or operation of Property or the conduct of its business requires such qualification except to the extent that the failure to comply therewith could not, in the aggregate, reasonably be expected to have a Material Adverse Effect, (iv) is in compliance with its Constituent Documents and (v) is in compliance with all Requirements of Law (other than its Constituent Documents) except to the extent that the failure to comply therewith could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(b) Each Loan Party has all Permits necessary for the ownership and, if any Loan Party is the operator, operation of its Properties and the conduct of its businesses except for those Permits the failure

of which to have could not reasonably be expected to have a Material Adverse Effect, and is in compliance in all material respects with the terms and conditions of all such Permits.

3.4 Entity Power; Authorization; Enforceable Obligations. Each Loan Party has the power and authority (corporate or otherwise), and the legal right, to make, deliver and perform the Loan Documents to which it is a party and, in the case of Borrower, to borrow hereunder. Each Loan Party has taken all necessary corporate or other action to authorize the execution, delivery and performance of the Loan Documents to which it is a party and, in the case of Borrower, to authorize the borrowings on the terms and conditions of this Agreement. No consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with the borrowings hereunder or the execution, delivery, performance, validity or enforceability of this Agreement or any of the other Loan Documents except (i) consents, authorizations, filings and notices described in Schedule 3.4, which consents, authorizations, filings and notices have been obtained or made and are in full force and effect and (ii) the filings referred to in Section 3.21. Each Loan Document has been duly executed and delivered on behalf of each Loan Party that is a party thereto. This Agreement constitutes, and each other Loan Document upon execution will constitute, a legal, valid and binding obligation of each Loan Party that is a party thereto, enforceable against each such Loan Party in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law).

3.5 No Legal Bar. The execution, delivery and performance of this Agreement and the other Loan Documents, the borrowings hereunder and the use of the proceeds thereof will not violate any Requirement of Law or any Contractual Obligation of any Loan Party and will not result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any Requirement of Law or any such Contractual Obligation (other than the Liens created by the Security Documents). No Requirement of Law or Contractual Obligation applicable to any Loan Party could reasonably be expected to have a Material Adverse Effect. No performance of a Contractual Obligation by any Loan Party, either unconditionally or upon the happening of an event, would result in the creation of a Lien (other than a Permitted Lien) on the Property of any Loan Party.

3.6 No Indebtedness; No Material Litigation.

ARTICLE VIII
THE AGENTS

Each Lender hereby irrevocably designates and appoints the Agents as the agents of such Lender under this Agreement and the other Loan Documents, and each Lender irrevocably authorizes each Agent, in such capacity, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to such Agent by the terms of this Agreement and the other Loan Documents,

together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, no Agent shall have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against any Agent.

8.2 Delegation of Duties. Each Agent may execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys in fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. No Agent shall be responsible for the negligence or misconduct of any agents or attorneys-in fact selected by it with reasonable care.

8.3 Exculpatory Provisions. Neither any Agent nor any of its officers, directors, employees, agents, attorneys in fact or affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except to the extent that any of the foregoing are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted solely and proximately from its or such Person’s own gross negligence or willful misconduct) or (ii) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by any Loan Party or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Agents under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of any Loan Party to perform its obligations hereunder or thereunder. The Agents shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of any Loan Party.

8.4 Reliance by Agents. Each Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, counsel to the Loan Parties), independent accountants and other experts selected by such Agent. The Agents may deem and treat the payee of any Note as the owner thereof for all purposes unless such Note shall have been transferred in accordance with Section 9.6 and all actions required by such Section in connection with such transfer shall have been taken. Each Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if so specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. Each Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or, if so specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Loans.

8.5 Notice of Default. No Agent shall be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless such Agent shall have received notice from a Lender or Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that the Administrative Agent shall receive such a notice, the Administrative Agent shall give notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably

directed by the Required Lenders (or, if so specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement); provided that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders.

8.6 Non Reliance on the Agents and Other Lenders. Each Lender expressly acknowledges that neither any of the Agents nor any of their respective officers, directors, employees, agents, attorneys and other advisors, partners, attorneys in fact or affiliates have made any representations or warranties to it and that no act by any Agent hereafter taken, including any review of the affairs of a Loan Party or any affiliate of a Loan Party, shall be deemed to constitute any representation or warranty by any Agent to any Lender. Each Lender represents to the Agents that it has, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates and made its own decision to make its Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, no Agent shall have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of any Loan Party or any affiliate of a Loan Party that may come into the possession of any Agent or any of its officers, directors, employees, agents, attorneys and other advisors, partners, attorneys in fact or affiliates.

8.7 Indemnification. The Lenders agree to indemnify each Agent in its capacity as such (to the extent not reimbursed by any Loan Party and without limiting the obligation of any Loan Party to do so), ratably according to their respective Aggregate Exposure Percentages in effect on the date on which indemnification is sought under this Section (or, if indemnification is sought after the date upon which the Commitments shall have terminated and the Loans shall have been paid in full, ratably in accordance with such Aggregate Exposure Percentages immediately prior to such date), for, and to save each Agent harmless from and against, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (including, at any time following the payment of the Loans) be imposed on, incurred by or asserted against such Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by such Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted solely and proximately from such Agent’s gross negligence or willful misconduct. The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder.

8.8 Agents in their Individual Capacities. Each Agent and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with any Loan Party as though such Agent were not an Agent. With respect to its Loans made or renewed by it, each Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may

exercise the same as though it were not an Agent, and the terms “Lender” and “Lenders” shall include each Agent in their individual capacities.

8.9 Successor Administrative Agent. The Administrative Agent may resign as Administrative Agent upon 10 days’ notice to the Lenders and Borrower. If the Administrative Agent shall resign as Administrative Agent under this Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall (unless an Event of Default shall have occurred and be continuing) be subject to approval by Borrower (which approval shall not be unreasonably withheld, conditioned or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and the term “Administrative Agent” shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent’s rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Loans. If no successor agent has accepted appointment as Administrative Agent by the date that is 10 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective, and the Lenders shall assume and perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above. After any retiring Administrative Agent’s resignation as Administrative Agent, the provisions of this Article VIII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents.

8.10 Authorization to Release Liens and Guarantees. The Administrative Agent is hereby irrevocably authorized by each of the Lenders to effect any release of Liens or guarantee obligations contemplated by Section 9.15.

8.11 Arranger; Syndication Agent. Each of the Syndication Agent and the Arranger, in its respective capacity as such, shall have no duties or responsibilities, and shall incur no liability, under this Agreement and the other Loan Documents.

8.12 Withholding Tax.

(a) To the extent required by any applicable law, the Administrative Agent may withhold from any interest payment to any Lender an amount equivalent to any applicable withholding tax. If the forms or other documentation required by Section 2.11(f) are not delivered to the Administrative Agent, then the Administrative Agent may withhold from any interest payment to any Lender not providing such forms or other documentation, a maximum amount of the applicable withholding tax.

(b) If the Internal Revenue Service or any authority of the United States 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, was not properly executed, or because such Lender failed to notify the Administrative Agent of a change in circumstances which rendered the exemption from, or reduction of, withholding tax ineffective, or for any other reason), such Lender shall indemnify the Administrative Agent 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, including legal expenses, allocated staff costs and any out of pocket expenses.

(c) If any Lender sells, assigns, grants a participation in, or otherwise transfers its rights under this Agreement, the purchaser, assignee, participant or transferee, as applicable, shall comply and be bound by the terms of Sections 2.11(f) and 8.12; provided that with respect to any Participant, as set

forth in Section 9.6(b), such Participant shall only be required to comply with the requirements of Sections 2.11(f) and 8.12 if such Participant seeks to obtain the benefits of Section 2.11.

provided that any notice, request or demand to or upon any Agent or any Lender shall not be effective until received.

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

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

9.4 Survival of Representations and Warranties. All representations and warranties made herein, in the other Loan Documents and in any document, certificate or statement delivered pursuant hereto or in connection herewith shall survive the execution and delivery of this Agreement and the making of the Loans and other extensions of credit hereunder.

9.5 Payment of Expenses. Borrower agrees (a) to pay or reimburse the Agents for all their reasonable out of pocket costs and expenses incurred in connection with the syndication of the Loans and the development, preparation and execution of, and any amendment, supplement or modification to, this Agreement and the other Loan Documents and any other documents prepared in connection herewith or therewith, and the consummation and administration of the transactions contemplated hereby and thereby, including, the reasonable fees and disbursements and other charges of counsel and consultants to the Administrative Agent and the charges of Intralinks, (b) to pay or reimburse each Lender and the Agents for all their costs and expenses incurred in connection with the enforcement or preservation of any rights under this Agreement, the other Loan Documents and any other documents prepared in connection herewith or therewith, including, the fees and disbursements of counsel (including the allocated fees and disbursements and other charges of in-house counsel) to each Lender and of counsel to the Agents, (c) to pay, indemnify, or reimburse each Lender and the Agents for, and hold each Lender and the Agents harmless from, any and all recording and filing fees and any and all liabilities with respect to, or resulting from any delay in paying, stamp, excise and other taxes, if any, which may be payable or determined to be payable in connection with the execution and delivery of, or consummation or administration of any of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver or consent under or in respect of, this Agreement, the other Loan Documents and any such other documents, and (d) to pay, indemnify or reimburse each Lender, each Agent, their respective affiliates, and their respective officers, directors, trustees, employees, affiliates, shareholders, attorneys and other advisors, agents and controlling persons (each, an “Indemnitee”) for, and hold each Indemnitee harmless from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement, the other Loan Documents and any such other documents, including, any of the foregoing relating to the use of proceeds of the Loans or the violation of, noncompliance with or liability under, any Environmental Law applicable to the operations

of any Loan Party or the use by unauthorized persons of information or other materials sent through electronic, telecommunications or other information transmission systems that are intercepted by such persons and the fees and disbursements and other charges of legal counsel in connection with claims, actions or proceedings by any Indemnitee against Borrower hereunder (all the foregoing in this clause (d), collectively, the “Indemnified Liabilities”); provided that Borrower shall have no obligation hereunder to any Indemnitee with respect to Indemnified Liabilities to the extent such Indemnified Liabilities are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted solely and proximately from the gross negligence or willful misconduct of such Indemnitee. No Indemnitee shall be liable for any damages arising from the use by unauthorized persons of information or other materials sent through electronic, telecommunications or other information transmission systems that are intercepted by such persons or for any special, indirect, consequential or punitive damages in connection with the Loans. Without limiting the foregoing, and to the extent permitted by applicable law, each of Holdings and Borrower agrees not to assert and to cause its Subsidiaries not to assert, and hereby waives and agrees to cause its Subsidiaries so to waive, all rights for contribution or any other rights of recovery with respect to all claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses of whatever kind or nature, under or related to Environmental Laws, that any of them might have by statute or otherwise against any Indemnitee. All amounts due under this Section 9.5 shall be payable not later than ten days after written demand therefor. Statements payable by Borrower pursuant to this Section shall be submitted to Borrower at the address of Borrower set forth in Section 9.2, or to such other Person or address as may be hereafter designated by Borrower in a notice to the Administrative Agent. The agreements in this Section 9.5 shall survive repayment of the Loans and all other amounts payable hereunder.

9.6 Successors and Assigns; Participations and Assignments.

(a) This Agreement shall be binding upon and inure to the benefit of Holdings, Borrower, the Lenders, the Agents, all future holders of the Loans and their respective successors and assigns, except that neither Holdings nor Borrower may assign or transfer any of its respective rights or obligations under this Agreement without the prior written consent of the Agents and each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void).

(b) Any Lender may, without the consent of Borrower or any other Person, in accordance with applicable law, at any time sell to one or more banks, financial institutions or other entities (each, a “Participant”) participating interests in any Loan owing to such Lender, any Commitment of such Lender or any other interest of such Lender hereunder and under the other Loan Documents. In the event of any such sale by a Lender of a participating interest to a Participant, such Lender’s obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Loan for all purposes under this Agreement and the other Loan Documents, and Borrower and the Agents shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and the other Loan Documents. In no event shall any Participant under any such participation have any right to approve any amendment or waiver of any provision of any Loan Document, or any consent to any departure by any Loan Party therefrom, except to the extent that such amendment, waiver or consent would require the consent of all Lenders pursuant to Section 9.1. Borrower agrees that if amounts outstanding under this Agreement and the Loans are due or unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall, to the maximum extent permitted by applicable law, be deemed to have the right of setoff in respect of its participating interest in amounts owing under this Agreement to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement, provided that, in purchasing such participating interest, such Participant shall be deemed to have agreed to share with the Lenders the proceeds thereof as provided in Section 9.7(a) as fully as if such

Participant were a Lender hereunder. Borrower also agrees that each Participant shall be entitled to the benefits of Sections 2.10 and 2.11 with respect to its participation in the Commitments and the Loans outstanding from time to time as if such Participant were a Lender; provided that, in the case of Section 2.11, such Participant shall have complied with the requirements of Section 2.11 and Section 8.12, and; provided, further, that no Participant shall be entitled to receive any greater amount pursuant to any such Section than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred by such transferor Lender to such Participant had no such transfer occurred.

(c) Any Lender (an “Assignor”) may, without the consent of any Loan Party, in accordance with applicable law and upon written notice to the Administrative Agent, at any time and from time to time assign to any Lender or any affiliate, Related Fund or Control Investment Affiliate thereof or, with the consent of the Administrative Agent (which, in each case, shall not be unreasonably withheld, conditioned or delayed) (provided that no such consent need be obtained by the Administrative Agent or its affiliates), to an additional bank, financial institution or other entity (an “Assignee”) all or any part of its rights and obligations under this Agreement pursuant to an Assignment and Acceptance, substantially in the form of Exhibit J (an “Assignment and Acceptance”), executed by such Assignee and such Assignor (and, where the consent of Borrower or the Administrative Agent is required pursuant to the foregoing provisions, by Borrower and such other Persons) and delivered to the Administrative Agent for its acceptance and recording in the Register; provided that no such assignment to an Assignee (other than any Lender or any affiliate thereof) shall be in an aggregate principal amount of less than $5,000,000 (other than, in each case, in the case of an assignment of all of a Lender’s interests under this Agreement), unless otherwise agreed by Borrower and the Administrative Agent. Upon such execution, delivery, acceptance and recording, from and after the effective date determined pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Lender hereunder with Commitments or Loans as set forth therein, and (y) the Assignor thereunder shall, to the extent provided in such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of an Assignor’s rights and obligations under this Agreement, such Assignor shall cease to be a party hereto, except as to Sections 2.10, 2.11, 8.12 and 9.5 in respect of the period prior to such effective date). For purposes of the minimum assignment amounts set forth in this Section 9.6(c), multiple assignments by two or more Related Funds shall be aggregated.

(d) The Administrative Agent shall, on behalf of Borrower, maintain at its address referred to in Section 9.2 a copy of each Assignment and Acceptance delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Loans owing to, each Lender from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and Borrower, each Agent and the Lenders shall treat each Person whose name is recorded in the Register as the owner of the Loans and any Note evidencing such Loans recorded therein for all purposes of this Agreement. Any assignment of any Loan, whether or not evidenced by a Note, shall be effective only upon appropriate entries with respect thereto being made in the Register (and each Note shall expressly so provide). Any assignment or transfer of all or part of a Loan evidenced by a Note shall be registered on the Register only upon surrender for registration of assignment or transfer of the Note evidencing such Loan, accompanied by a duly executed Assignment and Acceptance; thereupon one or more new Notes in the same aggregate principal amount shall be issued to the designated Assignee, and the old Notes shall be returned by the Administrative Agent to Borrower marked “canceled”. The Register shall be available for inspection by Borrower or any Lender (with respect to any entry relating to such Lender’s Loans) at any reasonable time and from time to time upon reasonable prior notice.

(e) Upon its receipt of an Assignment and Acceptance executed by an Assignor and an Assignee (and, in any case where the consent of any other Person is required by Section 9.6(c), by each

such other Person), the Administrative Agent shall (i) promptly accept such Assignment and Acceptance and (ii) on the effective date determined pursuant thereto record the information contained therein in the Register and give notice of such acceptance and recordation to Borrower. On or prior to such effective date, Borrower, at its own expense, upon request, shall execute and deliver to the Administrative Agent (in exchange for the applicable Note, if any, of the assigning Lender) new Note or Notes to the order of such Assignee in an amount equal to the Commitment or Loan assumed or acquired by it pursuant to such Assignment and Acceptance and, if the Assignor has retained a Commitment or Loan, as the case may be, upon request, a new Note or Notes to the order of the Assignor in an amount equal to the Commitment or Loans, as the case may be, retained by it hereunder. Such new Note or Notes shall be dated the Closing Date and shall otherwise be in the form of the Note or Notes replaced thereby.

(f) For avoidance of doubt, the parties to this Agreement acknowledge that the provisions of this Section concerning assignments of Loans and Notes relate only to absolute assignments and that such provisions do not prohibit assignments creating security interests in Loans and Notes, including, any pledge or assignment by a Lender of any Loan or Note to any Federal Reserve Bank in accordance with applicable law.

(g) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Lender to the Administrative Agent and Borrower, the option to provide to Borrower all or any part of any Loan that such Granting Lender would otherwise be obligated to make to Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any state thereof. In addition, notwithstanding anything to the contrary in this Section 9.6(g), any SPC may (x) with notice to, but without the prior written consent of, Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Lender, or with the prior written consent of Borrower and the Administrative Agent (which consent shall not be unreasonably withheld, conditioned or delayed) to any financial institutions providing liquidity or credit support to or for the account of such SPC to support the funding or maintenance of Loans, and (y) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC; provided that non-public information with respect to Borrower may be disclosed only with Borrower’s consent which will not be unreasonably withheld, conditioned or delayed. This Section 9.6(g) may not be amended without the written consent of any SPC with Loans outstanding at the time of such proposed amendment.

9.7 Adjustments; Set off

(a) If any Lender (a “Benefitted Lender”) shall at any time receive any payment of all or part of the Obligations owing to it, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set off, pursuant to events or proceedings of the nature referred to in clause (f) of Article

VII, or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of such other Lender’s Obligations, such Benefitted Lender shall purchase for cash from the other Lenders a participating interest in such portion of each such other Lender’s Obligations, or shall provide such other Lenders with the benefits of any such collateral, as shall be necessary to cause such Benefitted Lender to share the excess payment or benefits of such collateral ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such Benefitted Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest.

(b) In addition to any rights and remedies of the Lenders provided by law, each Lender shall have the right, without prior notice to Holdings or Borrower, any such notice being expressly waived by Holdings and Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by Holdings or Borrower hereunder (whether at the stated maturity, by acceleration or otherwise), to set off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of Holdings or Borrower, as the case may be. Each Lender agrees to notify promptly Borrower and the Administrative Agent after any such setoff and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such setoff and application.

9.8 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of an executed signature page of this Agreement by facsimile transmission shall be effective as delivery of a manually executed counterpart hereof. A set of the copies of this Agreement signed by all the parties shall be lodged with Borrower and the Administrative Agent.

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

9.10 Integration; Construction.

(a) This Agreement and the other Loan Documents represent the entire agreement of Borrower, Holdings, the Agents and the Lenders with respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by any Agent or any Lender relative to the subject matter hereof not expressly set forth or referred to herein or in the other Loan Documents.

(b) Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person.

9.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND

CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

9.12 Submission To Jurisdiction; Waivers. Each of Holdings and Borrower hereby irrevocably and unconditionally:

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

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

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to Holdings or Borrower, as the case may be, at its address set forth in Section 9.2 or at such other address of which the Administrative Agent shall have been notified pursuant thereto;

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

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

9.13 Acknowledgments. Each of Holdings and Borrower hereby acknowledges that:

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

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

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

9.14 Confidentiality. Each of the Agents and the Lenders agrees to keep confidential all non-public information provided to it by any Loan Party pursuant to this Agreement that is designated by such Loan Party as confidential; provided that nothing herein shall prevent any Agent or any Lender from disclosing any such information (a) to any Agent, any other Lender or any affiliate of any thereof, (b) to any Participant or Assignee (each, a “Transferee”) or prospective Transferee that agrees to comply with the provisions of this Section or substantially equivalent provisions, (c) to any of its employees, directors, agents, attorneys, accountants and other professional advisors, (d) upon the request or demand of any Governmental Authority having jurisdiction over it, (e) in response to any order of any court or other

Governmental Authority or as may otherwise be required pursuant to any Requirement of Law, (f) if requested or required to do so in connection with any litigation or similar proceeding, (g) that has been publicly disclosed other than in breach of this Section, (h) to the National Association of Insurance Commissioners or any similar organization or any nationally recognized rating agency that requires access to information about a Lender’s investment portfolio in connection with ratings issued with respect to such Lender or (i) in connection with the exercise of any remedy hereunder or under any other Loan Document. Notwithstanding anything to the contrary in the foregoing sentence or any other express or implied agreement, arrangement or understanding, the parties hereto hereby agree that, from the commencement of discussions with respect to the financing provided hereunder, any party hereto (and each of its employees, representatives, or agents) is permitted to disclose to any and all persons, without limitation of any kind, the tax structure and tax aspects of the transactions contemplated hereby, and all materials of any kind (including opinions or other tax analyses) related to such tax structure and tax aspects.

9.15 Release of Collateral and Guarantee Obligations.

(a) Notwithstanding anything to the contrary contained herein or in any other Loan Document, upon request of Borrower in connection with any Disposition of Property permitted by the Loan Documents (other than to a Loan Party), the Administrative Agent shall (without notice to, or vote or consent of, any Lender) take such actions as shall be required to release its security interest in any Collateral that is, or owned by any Person all the Capital Stock of which is, being Disposed of in such Disposition, and to release any Guarantee Obligations under any Loan Document of any Person being Disposed of in such Disposition, to the extent necessary to permit consummation of such Disposition in accordance with the Loan Documents; provided that Borrower shall have delivered to the Administrative Agent, at least ten Business Days prior to the date of the proposed release (or such shorter period agreed to by the Administrative Agent), a written request for release identifying the relevant Collateral being Disposed of in such Disposition and the terms of such Disposition in reasonable detail, including the date thereof, the price thereof and any expenses in connection therewith, together with a certification by Borrower stating that such transaction is in compliance with this Agreement and the other Loan Documents and that the proceeds of such Disposition will be applied in accordance with this Agreement and the other Loan Documents.

(b) Notwithstanding anything to the contrary contained herein or any other Loan Document, when all Obligations have been paid in full, all Commitments have terminated or expired, upon request of Borrower, the Administrative Agent shall (without notice to, or vote or consent of, any Lender) take such actions as shall be required to release its security interest in all Collateral, and to release all Guarantee Obligations provided for in any Loan Document. Any such release of Guarantee Obligations shall be deemed subject to the provision that such Guarantee Obligations shall be reinstated if after such release any portion of any payment in respect of the Obligations guaranteed thereby shall be rescinded or must otherwise be restored or returned upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of Borrower or any Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, Borrower or any Guarantor or any substantial part of its Property, or otherwise, all as though such payment had not been made.

9.16 Accounting Changes. In the event that any “Accounting Change” (as defined below) shall occur and such change results in a change in the method of calculation of financial covenants, standards or terms in this Agreement, then Holdings, Borrower and the Administrative Agent agree to enter into negotiations in order to amend such provisions of this Agreement so as to equitably reflect such Accounting Change with the desired result that the criteria for evaluating the consolidated financial condition of Holdings and Borrower shall be the same after such Accounting Change as if such Accounting Change had not been made. Until such time as such an amendment shall have been executed

and delivered by Holdings, Borrower, the Administrative Agent and the Required Lenders, all financial covenants, standards and terms in this Agreement shall continue to be calculated or construed as if such Accounting Change had not occurred. “Accounting Change” refers to any change in accounting principles required by the promulgation of any rule, regulation, pronouncement or opinion by the Financial Accounting Standards Board of the American Institute of Certified Public Accountants or, if applicable, the SEC.

9.17 WAIVERS OF JURY TRIAL. THE BORROWER, HOLDINGS, THE ARRANGER, THE AGENTS AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN (IN EACH CASE, WHETHER FOR CLAIMS SOUNDING IN CONTRACT OR IN TORT OR OTHERWISE).
