(b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent its respective share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to each Tranche 2/3 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 respective Tranche 2/3 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 such Tranche 2/3 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 such Tranche 2/3 Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

Section 2.05. Interest Elections. (a) Each Borrowing initially shall be of the Type and Tranche 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. Thereafter, the respective Tranche 2/3 Borrower may elect to convert such Borrowing of the same Tranche to a different Type of such Tranche or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section. Subject to the other provisions of this Section 2.05, the respective Tranche 2/3 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 respective Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing.

(b) To make an election pursuant to this Section 2.05, a Tranche 2/3 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 such Tranche 2/3 Borrower were requesting a Borrowing of the Type and Tranche resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by such Tranche 2/3 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 (iv) and (v) 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 such Borrowing consists of Tranche 2 Loans or Tranche 3 Loans;

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

(v) 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 such Tranche 2/3 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 relevant Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e) If any Tranche 2/3 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 be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies such Tranche 2/3 Borrower, then, so long as an 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 2.06. Termination and Reduction of Tranche 1 Commitments. (a) Unless previously terminated, the Tranche 1 Commitments shall terminate on the Commitment Expiration Date.

Each such reduction shall be applied to the Tranche 1 Commitments of the Tranche 1 Lenders on a pro rata basis based on the amount of such Tranche 1 Lenders’ respective Tranche 1 Commitments.

(d) The Designated Subsidiary Borrowers shall notify the Administrative Agent of any election to terminate or reduce the Tranche 1 Commitments under paragraph (c) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof.

Each notice delivered by the Designated Subsidiary Borrowers pursuant to this Section 2.06 shall be irrevocable; provided that a notice of termination of Tranche 1 Commitments delivered by the Designated Subsidiary Borrowers may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Designated Subsidiary Borrowers (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied.

Notwithstanding

anything to the contrary contained in this Section or elsewhere in this Agreement, any reduction to the Tranche 2 Commitment shall be applied pro rata to the Total Tranche 2 Commitment and Total Tranche 3 Commitment based on the Tranche 2 Revolving Percentage and the Tranche 3 Revolving Percentage, in each case as in effect at the time of any such reduction. Each reduction to the Total Tranche 2 Commitment shall be applied to the Tranche 2 Commitments of each Tranche 2 Lender on a pro rata basis based on the amount of such Tranche 2 Lenders’ respective Tranche 2 Commitments.

(d) The Tranche 2/3 Borrowers shall notify the Administrative Agent of any election to terminate or reduce the Tranche 2 Commitments under paragraph (c) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof.

(l) Notwithstanding the foregoing provisions of this Section 2.10, if at any time the mandatory repayment of Loans pursuant to Section 2.10(g), (h), (i) or (j) would result in any Tranche 2/3 Borrower incurring breakage costs under Section 2.15 as a result of Eurodollar Loans being repaid other than on the last day of an Interest Period applicable hereto (any such Eurodollar Loans, “Affected Loans”), such Tranche 2/3 Borrower may elect, by written notice to the Administrative Agent, to have the provisions of the following sentence be applicable so long as no Default or Event of Default then exists. At the time any Affected Loans are otherwise required to be prepaid, such Tranche 2/3 Borrower may elect to deposit 100% (or such lesser percentage elected by such Tranche 2/3 Borrower as not being repaid) of the principal amounts that otherwise would have been paid in respect of the Affected Loans with the Administrative

Agent to be held as security for the obligations of such Tranche 2/3 Borrower hereunder pursuant to a cash collateral agreement to be entered into in form and substance satisfactory to the Administrative Agent and shall provide for investments of such deposits as directed by such Tranche 2/3 Borrower and satisfactory to the Administrative Agent, with such cash collateral to be released from such cash collateral account (and applied to repay the principal amount of such Eurodollar Loans) upon each occurrence thereafter of the last day of an Interest Period applicable to such Eurodollar Loans (or such earlier date or dates as shall be requested by such Tranche 2/3 Borrower, with the amount to be so released and applied on the last day of each Interest Period to be the amount of such Eurodollar Loans to which such Interest Period applies (or, if less, the amount remaining in such cash collateral account); provided that (i) interest in respect of such Affected Loans shall continue to accrue thereon at the rate provided hereunder until such Affected Loans have been repaid in full and (ii) at any time while an Event of Default has occurred and is continuing or upon written notice from the Required Lenders, the Required Lenders may direct the Administrative Agent (in which case the Administrative Agent shall, and is hereby authorized by such Tranche 2/3 Borrower to, follow said directions) to apply any or all proceeds then on deposit in such collateral account to the payment of such Affected Loans. The Tranche 2/3 Borrower agrees to pay the balance of any Affected Loan if the amount on deposit is not sufficient. All risk of loss in respect of investments made as contemplated in this Section 2.10(l) shall be on such Tranche 2/3 Borrower. Under no circumstances shall the Administrative Agent be liable or accountable to such Tranche 2/3 Borrower or any other Person for any decrease in the value of the cash collateral account or for any loss resulting from the sale of any investment so made.

(f) Each Borrower agrees to pay to the Administrative Agent for pro rata distribution to each Tranche 1 Lender (based on their respective Tranche 1 Percentages), a fee in respect of each Tranche 1 Letter of Credit (the “Tranche 1 Letter of Credit Fee”) issued for the account of such Borrower computed at a rate per annum equal to the Applicable Rate for Tranche 1 Letter of Credit Fees, on the daily Stated Amount of such Tranche 1 Letter of Credit. Accrued Tranche 1 Letter of Credit Fees shall be due and payable quarterly in arrears on the last Business Day of each calendar quarter and upon the first day on or after the termination of the Total Tranche 1 Commitment upon which no Tranche 1 Letters of Credit remain outstanding.

(g) Each Borrower agrees to pay to the Administrative Agent for pro rata distribution to each Tranche 2 Lender (based on their respective Tranche 2 Percentages), a fee in respect of each Tranche 2 Letter of Credit (the “Tranche 2 Letter of Credit Fee”) issued for the account of such Borrower computed at a rate per annum equal to the Applicable Rate for Tranche 2 Letter of Credit Fees, on the daily Stated Amount of such Tranche 2 Letter of Credit. Accrued Tranche 2 Letter of Credit Fees shall be due and payable quarterly in arrears on the last Business Day of each calendar quarter and upon the first day on or after the termination of the Total Tranche 2 Commitment upon which no Tranche 2 Letters of Credit remain outstanding.

Section 2.12. Interest. (a) The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Rate.

(b) The Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted 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 any 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 2.12 or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section 2.12.

(d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and on the Commitment Expiration Date; provided that (i) interest accrued pursuant to paragraph (c) of this Section 2.12 shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Loan prior to the Commitment Expiration Date), 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 Adjusted LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

Section 2.13. 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 Adjusted LIBO Rate for such Interest Period; or

(b) the Administrative Agent is advised by the Required Lenders that the Adjusted 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 respective Tranche 2/3 Borrower and the relevant Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies such Tranche 2/3 Borrower and the relevant Lenders that the circumstances giving rise to such notice no longer exist, (i) in the case of clauses (a) and (b) above, 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 2.14. Increased Costs. (a) If any Change in Law shall:

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

(ii) impose on any Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender;

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 to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or otherwise), then the Parent Borrower, ARL, ARC and AIC each will pay, severally in accordance with its respective Facility-wide Liability Percentage and not jointly, to such Lender, as the case may be, such additional amount or amounts as will compensate such Lender, as the case may be, for such additional costs incurred or reduction suffered.

(b) If any Lender 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 capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement or the Loans made by such Lender, to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy), then from time to time the Parent Borrower ARL, ARC and AIC each will pay, severally in accordance with its respective Facility-wide Liability Percentage and not jointly, to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

(c) A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the respective Tranche 2/3 Borrower and shall be conclusive absent manifest error. Such Tranche 2/3 Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such compensation; provided that no Tranche 2/3 Borrower shall be required to compensate a Lender pursuant to this Section for any increased costs or reductions incurred more than 90 days prior to the date that such Lender notifies such Tranche 2/3 Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’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 90-day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 2.15. 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 a mandatory prepayment under Section 2.10 or 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 Eurodollar Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.10(b) 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 a Borrower pursuant to Section 2.18, then, in any such event, such Tranche 2/3 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 which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar 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 shall be delivered to the respective Tranche 2/3 Borrower and shall be conclusive absent manifest error. Such Tranche 2/3 Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

Section 2.16. Taxes. (a) Any and all payments by or on account of any obligation of any Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if any Borrower 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) the Administrative Agent or Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Borrower shall make such deductions and (iii) such Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) In addition, each Borrower shall pay, severally and not jointly, any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

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

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

(e) Each Foreign Lender shall deliver to each Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by such Borrower (if any), or will comply with such other requirements, if any, as is currently applicable, as will permit payments under this Agreement to be made without withholding or at a reduced rate; provided, however, that such Borrower shall have furnished to each such Lender in a reasonably timely manner copies of such documentation and notice of such requirements together with applicable instructions; provided, further, that no such Lender shall have any obligation to provide such documentation or comply with such requirements if it would result in a material economic, legal or regulatory disadvantage to any such Lender.

(f) If the Administrative Agent or a Lender determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by a Borrower or with respect to which a Borrower has paid additional amounts pursuant to this Section 2.16, it shall pay over such refund to such Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by such Borrower under this Section 2.16 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 such Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to such 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 shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to such Borrower or any other Person.

(g) Any Lender that is not a Lender as of the Effective Date shall not be entitled to any greater payment under this Section 2.16 than such Lender’s assignor could have been entitled to absent such assignment except to the extent that the entitlement to a greater payment resulted from a Change in Law.

Section 2.17. Payments Generally; Pro Rata Treatment; Sharing of Set-offs. (a) Each Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or of amounts payable under Section 2.14, 2.15 or 2.16, or otherwise) prior to 12:00 noon, New York City time, on the date when due, in immediately available funds, without set-off or counterclaim in Dollars. 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 270 Park Avenue, New York, New York, except that payments pursuant to Sections 2.14, 2.15, 2.16 and 10.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, 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 then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any particular Obligation resulting in such Lender receiving payment of a greater proportion of such Obligation than the proportion of such

Obligation received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the related Obligations 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 of such Obligations; 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, (ii) the provisions of this paragraph shall not be construed to apply to any payment made by a 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 to any assignee or participant, other than to any Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply) and (iii) the provisions of this paragraph shall not be construed to apply to any payment received by any Tranche 1 Lender pursuant to the terms of the Security Documents. Each 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 such Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such participation.

(d) Unless the Administrative Agent shall have received notice from a Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that such Borrower will not make such payment, the Administrative Agent may assume that such Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount due. In such event, if such Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender 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(b) or 2.17(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

Section 2.18. Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under Section 2.14, 3A.04 or 3B.04, or if a Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.16, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans or Letters of Credit 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 2.14, 2.16, 3A.04 or 3B.04, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Parent Borrower, ARL, ARC and AIC each agrees to pay, severally in accordance with its respective Facility-wide Liability Percentage and

not jointly, 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 2.14, 3A.04 or 3B.04, or if a Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.16, or if any Lender defaults in its obligation to fund Loans hereunder, then the respective Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 10.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if such Lender accepts such assignment); provided that (i) such Borrower shall have received the prior written consent of the Administrative Agent, 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, 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 respective Borrower (in the case of all other amounts), (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.14, 3A.04 or 3B.04 or payments required to be made pursuant to Section 2.16, such assignment will result in a reduction in such compensation or payments and (iv) no assignments pursuant to this Section 2.18 shall be effective until all then outstanding Letters of Credit are returned by each respective beneficiary to the Issuing Agent for cancellation or exchange for new or amended Letters of Credit which give effect to such assignment (it being understood that to the extent the respective beneficiaries do not consent to such assignment, such assignment cannot occur). 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 such Borrower to require such assignment and delegation cease to apply.

Section 2.19. Additional Tranche 1 Commitments. (a) The Designated Subsidiary Borrowers shall have the right at any time and from time to time after the Effective Date and prior to the Commitment Expiration Date to request (so long as no Default of Event or Default is then in existence or would result therefrom) on one or more occasions that one or more Tranche 1 Lenders (and/or one or more other Persons which will become Tranche 1 Lenders as provided pursuant to clause (vi) below) provide Additional Tranche 1 Commitments and, subject to the applicable terms and conditions contained in this Agreement and the relevant Additional Tranche 1 Commitment Agreement, issue Tranche 1 Letters of Credit; it being understood and agreed, however, that (i) no Tranche 1 Lender shall be obligated to provide an Additional Tranche 1 Commitment as a result of any request by the Designated Subsidiary Borrowers, (ii) until such time, if any, as (x) such Tranche 1 Lender has agreed in its sole discretion to provide an Additional Tranche 1 Commitment and executed and delivered to the Administrative Agent an Additional Tranche 1 Commitment Agreement in respect thereof as provided in Section 2.19(b) and (y) such other conditions set forth in Section 2.19(b) shall have been satisfied, such Tranche 1 Lender shall not be obligated to issue any Tranche 1 Letters of Credit, in excess of the amounts provided for in Section 3A.01, as the case may be, before giving effect to such Additional Tranche 1 Commitments provided pursuant to this Section 2.19, (iii) any Tranche 1 Lender (and/or one or more other Persons which will become Tranche 1 Lenders as provided pursuant to clause (vi) below) may so provide an Additional Tranche 1 Commitment

without the consent of any other Tranche 1 Lender (it being understood and agreed that the consent of the Administrative Agent and the Issuing Agent (such consent (in either case) not to be unreasonably withheld or delayed) shall be required if any such Additional Tranche 1 Commitments are to be provided by a Person which is not already a Tranche 1 Lender), (iv) (x) each provision of Additional Tranche 1 Commitments on a given date pursuant to this Section 2.19 shall be in a minimum aggregate amount (for all Tranche 1 Lenders (including, in the circumstances contemplated by clause (vi) below, banks or other financial institutions who will become Tranche 1 Lenders)) of at least $1,000,000 and (y) the aggregate amount of Additional Tranche 1 Commitments provided pursuant to this Section 2.19 shall not exceed $50,000,000, (v) the up-front fees payable to any Person providing an Additional Tranche 1 Commitment in accordance with this Section 2.19 shall be as set forth in the relevant Additional Tranche 1 Commitment Agreement, (vi) if, on or after the tenth Business Day following the request by the Designated Subsidiary Borrowers of the then existing Tranche 1 Lenders (other than Defaulting Lenders) to provide Additional Tranche 1 Commitments pursuant to this Section 2.19 on the terms to be applicable thereto, the Designated Subsidiary Borrowers have not received Additional Tranche 1 Commitments in an aggregate amount equal to that amount of the Additional Tranche 1 Commitments which the Designated Subsidiary Borrowers desire to obtain pursuant to such request (as set forth in the notice provided by the Designated Subsidiary Borrowers to the Administrative Agent as provided above), then the Designated Subsidiary Borrowers may request Additional Tranche 1 Commitments from other Lenders and/or other NAIC approved banks or financial institutions (unless otherwise agreed by the Designated Subsidiary Borrowers and the Administrative Agent) in an aggregate amount equal to such deficiency on terms which are no more favorable to such other bank or financial institution in any respect than the terms offered to the existing Tranche 1 Lenders, and (vii) all actions taken by the Designated Subsidiary Borrowers pursuant to this Section 2.19 shall be done in coordination with the Administrative Agent.

(b) At the time of any provision of Additional Tranche 1 Commitments pursuant to this Section 2.19, (i) each Designated Subsidiary Borrower, the Administrative Agent, the Guarantor and each such Tranche 1 Lender or other bank or financial institution which agrees to provide an Additional Tranche 1 Commitment (each, an “Additional Tranche 1 Lender”) shall execute and deliver to the Administrative Agent an Additional Tranche 1 Commitment Agreement substantially in the form of Exhibit I-1, subject to such modifications in form and substance reasonably satisfactory to the Administrative Agent as may be necessary or appropriate (with the effectiveness of such Additional Tranche 1 Lender’s Additional Tranche 1 Commitment to occur upon delivery of such Additional Tranche 1 Commitment Agreement to the Administrative Agent, the payment of any fees required in connection therewith and the satisfaction of the other conditions in this Section 2.19 to the reasonable satisfaction of the Administrative Agent), (ii) all of the outstanding Tranche 1 Letters of Credit shall have been returned by each respective beneficiary to the Issuing Agent and shall either have been cancelled and/or exchanged for new or amended Tranche 1 Letters of Credit which give effect to such Additional Tranche 1 Commitment, (iii) if such Additional Tranche 1 Lender is not a United States person (as such term is defined in Section 7701(a)(3) of the Code) for U.S. Federal income tax purposes and such Additional Tranche 1 Lender is issuing Letters of Credit for the account of a U.S. Borrower or U.S. Borrowers, such Additional Tranche 1 Lender shall provide to such U.S. Borrower or U.S. Borrowers the appropriate Internal Revenue Service documentation described in Section 2.16, (iv) each Designated Subsidiary Borrower shall deliver to the Administrative

Agent resolutions authorizing the incurrence of the Obligations to be incurred pursuant to each Additional Tranche 1 Commitment, together with evidence of good standing of such Designated Subsidiary Borrower (if requested) and (v) each Designated Subsidiary Borrower shall deliver to the Administrative Agent an opinion, in form and substance reasonably satisfactory to the Administrative Agent, from counsel to such Designated Subsidiary Borrowers reasonably satisfactory to the Administrative Agent and dated such date, covering such matters similar to those set forth in the opinions of counsel delivered to the Lenders on the Effective Date pursuant to Section 5.01(b) and such other matters as the Administrative Agent may reasonably request. The Administrative Agent shall promptly notify each Tranche 1 Lender as to the occurrence of each Additional Tranche 1 Commitment Date, and (x) on each such date, the Total Tranche 1 Commitment under, and for all purposes of, this Agreement shall be increased by the aggregate amount of such Additional Tranche 1 Commitments and (y) on each such date, Schedule 2.01 shall be deemed modified to reflect the revised Tranche 1 Commitments of the affected Tranche 1 Lenders.

Section 2.20. Additional Tranche 2 Commitments.

(a) Subject to and upon the terms and conditions set forth herein, each Designated Subsidiary Borrower may request the Issuing Agent, at any time and from time to time after the Effective Date and prior to the date which is 30 days prior to the Commitment Expiration Date, to issue on behalf of the Tranche 1 Lenders, for the account of such Designated Subsidiary Borrower and in support of, on a standby basis, Letter of Credit Supportable Obligations and, subject to and upon the terms and conditions set forth herein, the Issuing Agent agrees to issue on behalf of the Tranche 1 Lenders at any time and from time to time after the Effective Date and prior to the date which is 30 days prior to the Commitment Expiration Date, one or more irrevocable standby letters of credit in such form as may be approved by the Issuing Agent (each such letter of credit, a “Tranche 1 Letter of Credit” and, collectively, the “Tranche 1 Letters of Credit”). Notwithstanding the foregoing, the Issuing Agent shall be under no obligation to issue any Tranche 1 Letter of Credit if at the time of such issuance:

(i) any order, judgment or decree of any Governmental Authority or arbitrator shall purport by its terms to enjoin or restrain the Issuing Agent from issuing such Tranche 1 Letter of Credit or any requirement of law applicable to such Issuing Agent or any Tranche 1 Lender or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over the Issuing Agent or any Tranche 1 Lender shall prohibit, or request that the Issuing Agent or any Tranche 1 Lender refrain from, the issuance of letters of credit generally or such Tranche 1 Letter of Credit in particular or shall impose upon the Issuing Agent or any Lender with respect to such Tranche 1 Letter of Credit any restriction or reserve or capital requirement (for which the Issuing Agent or any Tranche 1 Lender is not otherwise compensated) not in effect on the Effective Date, or any unreimbursed loss, cost or expense which was not applicable, in effect or known to the Issuing Agent or any Tranche 1 Lender as of the Effective Date;

(ii) the conditions precedent set forth in Section 5.02 are not satisfied at that time; or

(iii) the Issuing Agent shall have received notice from any Borrower or the Required Lenders prior to the issuance of such Tranche 1 Letter of Credit of the type described in clause (vii) of Section 3A.01(b).

(b) Notwithstanding anything to the contrary contained in this Section 3A.01 or elsewhere in this Agreement (i) no Tranche 1 Letter of Credit shall be issued the Stated Amount of which, when added to the Tranche 1 Letter of Credit Outstandings (exclusive of Tranche 1 Unpaid Drawings which are repaid on the date of, and prior to the issuance of, the

respective Tranche 1 Letter of Credit) at such time, would exceed an amount equal to the Total Tranche 1 Commitment at such time; (ii) no Tranche 1 Letter of Credit shall be issued for the account of any Designated Subsidiary Borrower (other than ARC) the Stated Amount of which, when added to the Tranche 1 Letter of Credit Outstandings in respect of outstanding Tranche 1 Letters of Credit issued for the account of such Designated Subsidiary Borrower (exclusive of Tranche 1 Unpaid Drawings in respect of Tranche 1 Letters of Credit issued for the account of such Designated Subsidiary Borrower which are repaid on the date of, and prior to the issuance of, the respective Tranche 1 Letter of Credit) at such time would exceed an amount equal to the lesser of (x) such Designated Subsidiary Borrower’s Borrowing Base and (y) such Designated Subsidiary Borrower’s Sublimit; (iii) no Tranche 1 Letter of Credit shall be issued for the account of ARC the Stated Amount of which, when added to the Tranche 1 Letter of Credit Outstandings in respect of outstanding Tranche 1 Letters of Credit issued for the account of ARC (exclusive of Tranche 1 Unpaid Drawings in respect of Tranche 1 Letters of Credit issued for the account of ARC which are repaid on the date of, and prior to the issuance of, the respective Tranche 1 Letter of Credit) at such time would exceed an amount equal to ARC’s Borrowing Base; (iv) no Tranche 1 Letter of Credit shall be issued for the account of ARC the Stated Amount of which, when added to (x) the Tranche 1 Letter of Credit Outstandings applicable to ARC (exclusive of Tranche 1 Unpaid Drawings which are repaid on the date of, and prior to the issuance of, the respective Tranche 1 Letter of Credit) at such time, (y) the Tranche 2 Letter of Credit Outstandings applicable to ARC at such time and (z) the aggregate principal amount of all Tranche 2 Loans incurred by ARC and then outstanding, would exceed an amount equal to ARC’s Sublimit; (v) each Tranche 1 Letter of Credit shall have an expiry date occurring not later than one year after such Tranche 1 Letter of Credit’s date of issuance; provided that each such Tranche 1 Letter of Credit may by its terms automatically renew annually for one additional year unless the Issuing Agent notifies the beneficiary thereof, in accordance with the terms of such Tranche 1 Letter of Credit, that such Tranche 1 Letter of Credit will not be renewed; (vi) each Tranche 1 Letter of Credit shall be denominated in Dollars; and (vii) the Issuing Agent will not issue any Tranche 1 Letter of Credit after it has received written notice from any Borrower or the Required Lenders stating that a Default or an Event of Default exists until such time as the Issuing Agent shall have received a written notice of (x) rescission of such notice from the party or parties originally delivering the same or (y) a waiver of such Default or Event of Default by the Required Lenders (or, to the extent provided by Section 10.02, each of the Lenders).

(c) Each Tranche 1 Letter of Credit will be issued by the Issuing Agent on behalf of the Tranche 1 Lenders and each Tranche 1 Lender will participate in each Tranche 1 Letter of Credit pro rata in accordance with its Tranche 1 Percentage. The obligations of each Tranche 1 Lender under and in respect of each Tranche 1 Letter of Credit are several, and the failure by any Tranche 1 Lender to perform its obligations hereunder or under any Tranche 1 Letter of Credit shall not affect the obligations of the respective Designated Subsidiary Borrower toward any other party hereto nor shall any other such party be liable for the failure by such Tranche 1 Lender to perform its obligations hereunder or under any Tranche 1 Letter of Credit.

(d) Subject to and on the terms and conditions set forth herein, the Issuing Agent is hereby authorized by each Designated Subsidiary Borrower and the Tranche 1 Lenders to arrange for the issuance of any Tranche 1 Letter of Credit pursuant to Section 3A.01(a) and the amendment of any Tranche 1 Letter of Credit pursuant to Section 2.18, Section 2.19, Section 3A.06 and/or Section 10.04(b) by:

(i) completing the commencement date and the expiry date of such Tranche 1 Letter of Credit;

(ii) in the case of an amendment increasing or reducing the amount thereof, amending such Tranche 1 Letter of Credit in such manner as the Issuing Agent and the respective beneficiary may agree;

(iii) completing such Tranche 1 Letter of Credit with the participation of each Tranche 1 Lender as allocated pursuant to the terms hereof; and

(iv) executing such Tranche 1 Letter of Credit on behalf of each Tranche 1 Lender and following such execution delivering such Tranche 1 Letter of Credit to the beneficiary of such Tranche 1 Letter of Credit.

(e) Each Tranche 1 Letter of Credit shall be executed and delivered by the Issuing Agent in the name and on behalf of, and as attorney-in-fact for, each Tranche 1 Lender party to such Tranche 1 Letter of Credit, and the Issuing Agent shall act under each Tranche 1 Letter of Credit, and each Tranche 1 Letter of Credit shall expressly provide that the Issuing Agent shall act, as the agent of each Tranche 1 Lender to (a) receive drafts, other demands for payment and other documents presented by the beneficiary under such Tranche 1 Letter of Credit, (b) determine whether such drafts, demands and documents are in compliance with the terms and conditions of such Tranche 1 Letter of Credit and (c) notify such Tranche 1 Lender and such Designated Subsidiary Borrower that a valid drawing has been made and the date that the related Tranche 1 Unpaid Drawing is to be made; provided that the Issuing Agent shall have no obligation or liability for any Tranche 1 Unpaid Drawing under such Tranche 1 Letter of Credit, and each Tranche 1 Letter of Credit shall expressly so provide. Each Tranche 1 Lender hereby irrevocably appoints and designates the Issuing Agent as its attorney-in-fact, acting through any duly authorized officer of the Issuing Agent, solely for the purpose of executing and delivering in the name and on behalf of such Tranche 1 Lender each Tranche 1 Letter of Credit to be issued by such Tranche 1 Lender hereunder. Promptly upon the request of the Issuing Agent, each Tranche 1 Lender will furnish to the Issuing Agent such powers of attorney or other evidence as any beneficiary of any Tranche 1 Letter of Credit may reasonably request in order to demonstrate that the Issuing Agent has the power to act as attorney-in-fact for such Tranche 1 Lender to execute and deliver such Tranche 1 Letter of Credit.

Section 3A.02. Tranche 1 Letter of Credit Requests. (a) Whenever a Designated Subsidiary Borrower desires that a Tranche 1 Letter of Credit be issued, such Designated Subsidiary Borrower shall give the Administrative Agent and the Issuing Agent written notice (including by way of facsimile transmission, immediately confirmed in writing by submission of the original of such request by mail to the Issuing Agent) thereof prior to 11:00 A.M. (New York time) at least five Business Days (or such shorter period as may be acceptable to the Issuing Agent) prior to the proposed date of issuance (which shall be a Business Day), which written notice shall be in the form of Exhibit C-1 (each, a “Tranche 1 Letter of Credit Request”). Each Tranche 1 Letter of Credit Request shall include any other documents as the Issuing Agent customarily requires in connection therewith.

(b) The making of each Tranche 1 Letter of Credit Request shall be deemed to be a representation and warranty by the applicable Designated Subsidiary Borrower that such Tranche 1 Letter of Credit may be issued in accordance with, and it will not violate the requirements of, Section 3A.01(a) or (b).

(c) Upon its issuance of, or amendment to, any Tranche 1 Letter of Credit, the Issuing Agent shall promptly notify the respective Designated Subsidiary Borrower and the Tranche 1 Lenders of such issuance or amendment, which notice shall include a summary description of the Tranche 1 Letter of Credit actually issued and any amendments thereto.

Section 3A.03. Agreement to Repay Tranche 1 Letter of Credit Drawings. (a) Each Designated Subsidiary Borrower agrees to reimburse each Tranche 1 Lender, by making payment to the Administrative Agent in immediately available funds at the Payment Office, for any payment or disbursement made by such Tranche 1 Lender under any Tranche 1 Letter of Credit which has been issued for such Designated Subsidiary Borrower’s account (each such amount so paid or disbursed until reimbursed, a “Tranche 1 Unpaid Drawing”) no later than one Business Day following the date of such payment or disbursement, with interest on the amount so paid or disbursed by such Lender, to the extent not reimbursed prior to 1:00 P.M. (New York time) on the date of such payment or disbursement, from and including the date paid or disbursed to but not including the date such Tranche 1 Lender is reimbursed therefor at a rate per annum which shall be the Alternative Base Rate plus the Applicable Rate for Loans maintained as ABR Loans as in effect from time to time (plus an additional 2% per annum, payable on demand, if not reimbursed by the third Business Day after the date of such payment or disbursement).

(b) Each Designated Subsidiary Borrower’s obligation under this Section 3A.03 to reimburse each Tranche 1 Lender with respect to Tranche 1 Unpaid Drawings (including, in each case, interest thereon) shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which such Designated Subsidiary Borrower may have or have had against such Tranche 1 Lender, or the Issuing Agent, including, without limitation, any defense based upon the failure of any drawing under a Tranche 1 Letter of Credit to conform to the terms of the Tranche 1 Letter of Credit or any non-application or misapplication by the beneficiary of the proceeds of such drawing; provided, however, that no Designated Subsidiary Borrower shall be obligated to reimburse any Tranche 1 Lender for any wrongful payment made by such Tranche 1 Lender under a Tranche 1 Letter of Credit as a result of acts or omissions constituting willful misconduct or gross negligence on the part of such Tranche 1 Lender (as determined by a court of competent jurisdiction in a final and non-appealable decision).

Section 3A.04. Increased Costs. If after the Effective Date, a Change in Law shall either (i) impose, modify or make applicable any reserve, deposit, capital adequacy or similar requirement against letters of credit issued by or participated in by such Tranche 1 Lender, or (ii) impose on such Tranche 1 Lender any other conditions directly or indirectly affecting this Agreement or any Tranche 1 Letter of Credit; and the result of any of the foregoing is to increase the cost to such Tranche 1 Lender of issuing, maintaining or participating in any Tranche 1 Letter of Credit, or to reduce the amount of any sum received or receivable by such Tranche 1 Lender hereunder or reduce the rate of return on its capital with respect to Tranche 1

Letters of Credit, then, upon written demand to the respective Designated Subsidiary Borrower by such Tranche 1 Lender (with a copy to the Administrative Agent), such Designated Subsidiary Borrower agrees to pay to such Tranche 1 Lender such additional amount or amounts as will compensate such Tranche 1 Lender for such increased cost or reduction. A certificate submitted to the respective Designated Subsidiary Borrower by such Tranche 1 Lender (with a copy to the Administrative Agent), setting forth the basis for the determination of such additional amount or amounts necessary to compensate such Tranche 1 Lender as aforesaid shall be final and conclusive and binding on such Designated Subsidiary Borrower absent manifest error, although the failure to deliver any such certificate shall not release or diminish any Designated Subsidiary Borrower’s obligations to pay additional amounts pursuant to this Section 3A.04 upon subsequent receipt of such certificate; provided that such Designated Subsidiary Borrower shall not be required to compensate such Tranche 1 Lender pursuant to this Section 3A.04 for any increased costs or reductions incurred more than 90 days prior to the date that such Tranche 1 Lender notifies such Designated Subsidiary Borrower of the Change in Law giving rise to such increased costs or reductions and of such Tranche 1 Lender’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 90-day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 3A.05. Tranche 1 Letter of Credit Expiration Extensions. Each Tranche 1 Lender acknowledges that to the extent provided under the terms of any Tranche 1 Letter of Credit, the expiration date of such Tranche 1 Letter of Credit will be automatically extended for an additional year, without written amendment, unless at least 30 days prior to the expiration date of such Tranche 1 Letter of Credit, notice is given by the Issuing Agent to the beneficiary of such Tranche 1 Letter of Credit in accordance with the terms of the respective Tranche 1 Letter of Credit (a “Notice of Non-Extension”) that the expiration date of such Tranche 1 Letter of Credit will not be extended beyond its current expiration date. The Issuing Agent will give Notices of Non-Extension as to any or all outstanding Tranche 1 Letters of Credit if requested to do so by the Required Lenders pursuant to Article VIII. The Issuing Agent will give Notices of Non-Extension as to all outstanding Tranche 1 Letters of Credit if the Commitment Expiration Date has occurred.

Notwithstanding the foregoing, the Issuing Agent shall be under no obligation to issue any Tranche 2 Letter of Credit if at the time of such issuance:

(i) any order, judgment or decree of any Governmental Authority or arbitrator shall purport by its terms to enjoin or restrain the Issuing Agent from issuing such Tranche 2 Letter of Credit or any requirement of law applicable to such Issuing Agent or any Tranche 2 Lender or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over the Issuing Agent or any Tranche 2 Lender shall prohibit, or request that the Issuing Agent or any Tranche 2 Lender refrain from, the issuance of letters of credit generally or such Tranche 2 Letter of Credit in particular or shall impose upon the Issuing Agent or any Tranche 2 Lender with respect to such Tranche 2 Letter of Credit any restriction or reserve or capital requirement (for which the Issuing Agent or any Tranche 2 Lender is not otherwise compensated) not in effect on the Effective Date, or any unreimbursed loss, cost or expense which was not applicable, in effect or known to the Issuing Agent or any Tranche 2 Lender as of the Effective Date;

(ii) the conditions precedent set forth in Section 5.02 are not satisfied at that time; or

(iii) the Issuing Agent shall have received notice from any Borrower or the Required Lenders prior to the issuance of such Tranche 2 Letter of Credit of the type described in clause (vii) of Section 3B.01(b).

(b) Notwithstanding anything to the contrary contained in this Section 3B.01 or elsewhere in this Agreement, (i) no Tranche 2 Letter of Credit shall be issued the Stated Amount of which, when added to (x) the Tranche 2 Letter of Credit Outstandings (exclusive of Tranche 2 Unpaid Drawings which are repaid on the date of, and prior to the issuance of, the respective Tranche 2 Letter of Credit) at such time and (y) the aggregate principal amount of all Tranche 2 Loans then outstanding, would exceed, an amount equal to the Total Tranche 2

Commitment at such time; (ii) no Tranche 2 Letter of Credit shall be issued if any Tranche 2 Lender’s Tranche 2 Percentage of the Stated Amount of such Tranche 2 Letter of Credit, when added to such Tranche 2 Lender’s Tranche 2 Credit Exposure, would exceed the Tranche 2 Commitment of such Tranche 2 Lender at such time; (iii) no Tranche 2 Letter of Credit shall be issued for the account of ARC the Stated Amount of which, when added to (x) the Tranche 2 Letter of Credit Outstandings applicable to ARC (exclusive of Tranche 2 Unpaid Drawings which are repaid on the date of, and prior to the issuance of, the respective Tranche 2 Letter of Credit) at such time and (y) the aggregate principal amount of all Tranche 2 Loans incurred by ARC and then outstanding, would exceed an amount equal to $100,000,000 at such time; (iv) no Tranche 2 Letter of Credit shall be issued for the account of ARC if the Stated Amount thereof, when added to (x) the Tranche 1 Letter of Credit Outstandings in respect of Tranche 1 Letters of Credit issued for the account of ARC, (y) the Tranche 2 Letter of Credit Outstandings in respect of Tranche 2 Letters of Credit issued for the account of ARC and (z) the aggregate principal amount of all Tranche 2 Loans incurred by ARC and then outstanding, would exceed an amount equal to ARC’s Sublimit at such time; (v) each Tranche 2 Letter of Credit shall have an expiry date occurring not later than one year after such Tranche 2 Letter of Credit’s date of issuance; provided that each such Tranche 2 Letter of Credit may by its terms automatically renew annually for one additional year unless the Issuing Agent notifies the beneficiary thereof, in accordance with the terms of such Tranche 2 Letter of Credit, that such Tranche 2 Letter of Credit will not be renewed; (vi) each Tranche 2 Letter of Credit shall be denominated in Dollars; and (vii) the Issuing Agent will not issue any Tranche 2 Letter of Credit after it has received written notice from any Borrower or the Required Lenders stating that a Default or an Event of Default exists until such time as the Issuing Agent shall have received a written notice of (x) rescission of such notice from the party or parties originally delivering the same or (y) a waiver of such Default or Event of Default by the Required Lenders (or, to the extent provided by Section 10.02, each of the Lenders).

(c) Each Tranche 2 Letter of Credit will be issued by the Issuing Agent on behalf of the Tranche 2 Lenders and each Tranche 2 Lender will participate in each Tranche 2 Letter of Credit pro rata in accordance with its Tranche 2 Percentage. The obligations of each Tranche 2 Lender under and in respect of each Tranche 2 Letter of Credit are several, and the failure by any Tranche 2 Lender to perform its obligations hereunder or under any Tranche 2 Letter of Credit shall not affect the obligations of the respective Tranche 2/3 Borrower toward any other party hereto nor shall any other such party be liable for the failure by such Tranche 2 Lender to perform its obligations hereunder or under any Tranche 2 Letter of Credit.

(d) Subject to and on the terms and conditions set forth herein, the Issuing Agent is hereby authorized by each Tranche 2/3 Borrower and the Tranche 2 Lenders to arrange for the issuance of any Tranche 2 Letter of Credit pursuant to Section 3B.01(a) and the amendment of any Tranche 2 Letter of Credit pursuant to Section 2.18, Section 2.20, Section 3B.06 and/or Section 10.04(b) by:

(iii) completing such Tranche 2 Letter of Credit with the participation of each Tranche 2 Lender as allocated pursuant to the terms hereof; and

(iv) executing such Tranche 2 Letter of Credit on behalf of each Tranche 2 Lender and following such execution delivering such Tranche 2 Letter of Credit to the beneficiary of such Tranche 2 Letter of Credit.

(e) Each Tranche 2 Letter of Credit shall be executed and delivered by the Issuing Agent in the name and on behalf of, and as attorney-in-fact for, each Tranche 2 Lender party to such Tranche 2 Letter of Credit, and the Issuing Agent shall act under each Tranche 2 Letter of Credit, and each Tranche 2 Letter of Credit shall expressly provide that the Issuing Agent shall act, as the agent of each Tranche 2 Lender to (a) receive drafts, other demands for payment and other documents presented by the beneficiary under such Tranche 2 Letter of Credit, (b) determine whether such drafts, demands and documents are in compliance with the terms and conditions of such Tranche 2 Letter of Credit and (c) notify such Tranche 2 Lender and such Tranche 2/3 Borrower that a valid drawing has been made and the date that the related Tranche 2 Unpaid Drawing is to be made; provided that the Issuing Agent shall have no obligation or liability for any Tranche 2 Unpaid Drawing under such Tranche 2 Letter of Credit, and each Tranche 2 Letter of Credit shall expressly so provide. Each Tranche 2 Lender hereby irrevocably appoints and designates the Issuing Agent as its attorney-in-fact, acting through any duly authorized officer of the Issuing Agent, solely for the purpose of executing and delivering in the name and on behalf of such Tranche 2 Lender each Tranche 2 Letter of Credit to be issued by such Tranche 2 Lender hereunder. Promptly upon the request of the Issuing Agent, each Tranche 2 Lender will furnish to the Issuing Agent such powers of attorney or other evidence as any beneficiary of any Tranche 2 Letter of Credit may reasonably request in order to demonstrate that the Issuing Agent has the power to act as attorney-in-fact for such Tranche 2 Lender to execute and deliver such Tranche 2 Letter of Credit.

Section 3B.02. Tranche 2 Letter of Credit Requests. (a) Whenever a Tranche 2/3 Borrower desires that a Tranche 2 Letter of Credit be issued, such Tranche 2/3 Borrower shall give the Administrative Agent and the Issuing Agent written notice (including by way of facsimile transmission, immediately confirmed in writing by submission of the original of such request by mail to the Issuing Agent) thereof prior to 11:00 A.M. (New York time) at least five Business Days (or such shorter period as may be acceptable to the Issuing Agent) prior to the proposed date of issuance (which shall be a Business Day), which written notice shall be in the form of Exhibit C-2 (each, a “Tranche 2 Letter of Credit Request”). Each Tranche 2 Letter of Credit Request shall include any other documents as the Issuing Agent customarily requires in connection therewith.

(b) The making of each Tranche 2 Letter of Credit Request shall be deemed to be a representation and warranty by the applicable Tranche 2/3 Borrower that such Tranche 2 Letter of Credit may be issued in accordance with, and it will not violate the requirements of, Section 3B.01(a) or (b).

(c) Upon its issuance of, or amendment to, any Tranche 2 Letter of Credit, the Issuing Agent shall promptly notify the respective Tranche 2/3 Borrower and the Tranche 2 Lenders of such issuance or amendment, which notice shall include a summary description of the Tranche 2 Letter of Credit actually issued and any amendments thereto.

Section 3B.03. Agreement to Repay Tranche 2 Letter of Credit Drawings. (a) Each Tranche 2/3 Borrower agrees to reimburse each Tranche 2 Lender, by making payment to the Administrative Agent in immediately available funds at the Payment Office, for any payment or disbursement made by such Tranche 2 Lender under any Tranche 2 Letter of Credit which has been issued for such Tranche 2/3 Borrower’s account (each such amount so paid or disbursed until reimbursed, a “Tranche 2 Unpaid Drawing”) no later than one Business Day following the date of such payment or disbursement, with interest on the amount so paid or disbursed by such Tranche 2 Lender, to the extent not reimbursed prior to 1:00 P.M. (New York time) on the date of such payment or disbursement, from and including the date paid or disbursed to but not including the date such Tranche 2 Lender is reimbursed therefor at a rate per annum which shall be the Alternative Base Rate plus the Applicable Rate for Loans maintained as ABR Loans as in effect from time to time (plus an additional 2% per annum, payable on demand, if not reimbursed by the third Business Day after the date of such payment or disbursement).

(b) Each Tranche 2/3 Borrower’s obligation under this Section 3B.03 to reimburse each Tranche 2 Lender with respect to Tranche 2 Unpaid Drawings (including, in each case, interest thereon) shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which such Tranche 2/3 Borrower may have or have had against such Tranche 2 Lender, or the Issuing Agent, including, without limitation, any defense based upon the failure of any drawing under a Tranche 2 Letter of Credit to conform to the terms of the Tranche 2 Letter of Credit or any non-application or misapplication by the beneficiary of the proceeds of such drawing; provided, however, that no Tranche 2/3 Borrower shall be obligated to reimburse any Tranche 2 Lender for any wrongful payment made by such Tranche 2 Lender under a Tranche 2 Letter of Credit as a result of acts or omissions constituting willful misconduct or gross negligence on the part of such Tranche 2 Lender (as determined by a court of competent jurisdiction in a final and non-appealable decision).

Section 3B.04. Increased Costs. If after the Effective Date, a Change in Law shall either (i) impose, modify or make applicable any reserve, deposit, capital adequacy or similar requirement against letters of credit issued by or participated in by such Tranche 2 Lender, or (ii) impose on such Tranche 2 Lender any other conditions directly or indirectly affecting this Agreement or any Tranche 2 Letter of Credit; and the result of any of the foregoing is to increase the cost to such Tranche 2 Lender of issuing, maintaining or participating in any Tranche 2 Letter of Credit, or to reduce the amount of any sum received or receivable by such Tranche 2 Lender hereunder or reduce the rate of return on its capital with respect to Tranche 2 Letters of Credit, then, upon written demand to the respective Tranche 2/3 Borrower by such Tranche 2 Lender (with a copy to the Administrative Agent), such Tranche 2/3 Borrower agrees to pay to such Tranche 2 Lender such additional amount or amounts as will compensate such Tranche 2 Lender for such increased cost or reduction. A certificate submitted to the respective Tranche 2/3 Borrower by such Tranche 2 Lender (with a copy to the Administrative Agent), setting forth the basis for the determination of such additional amount or amounts necessary to compensate such Tranche 2 Lender as aforesaid shall be final and conclusive and binding on

such Tranche 2/3 Borrower absent manifest error, although the failure to deliver any such certificate shall not release or diminish any Tranche 2/3 Borrower’s obligations to pay additional amounts pursuant to this Section 3B.04 upon subsequent receipt of such certificate; provided that such Tranche 2/3 Borrower shall not be required to compensate such Tranche 2 Lender pursuant to this Section 3B.04 for any increased costs or reductions incurred more than 90 days prior to the date that such Tranche 2 Lender notifies such Tranche 2/3 Borrower of the Change in Law giving rise to such increased costs or reductions and of such Tranche 2 Lender’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 90-day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 3B.05. Tranche 2 Letter of Credit Expiration Extensions. Each Tranche 2 Lender acknowledges that to the extent provided under the terms of any Tranche 2 Letter of Credit, the expiration date of such Tranche 2 Letter of Credit will be automatically extended for an additional year, without written amendment, unless at least 30 days prior to the expiration date of such Tranche 2 Letter of Credit, a Notice of Non-Extension is given by the Issuing Agent to the beneficiary of such Tranche 2 Letter of Credit in accordance with the terms of the respective Tranche 2 Letter of Credit that the expiration date of such Tranche 2 Letter of Credit will not be extended beyond its current expiration date. The Issuing Agent will give Notices of Non-Extension as to any or all outstanding Tranche 2 Letters of Credit if requested to do so by the Required Lenders pursuant to Article VIII. The Issuing Agent will give Notices of Non-Extension as to all outstanding Tranche 2 Letters of Credit if the Commitment Expiration Date has occurred. The Issuing Agent will send a copy of each Notice of Non-Extension to the respective Tranche 2/3 Borrower concurrently with delivery thereof to the respective beneficiary, unless prohibited by law from doing so.

Section 3B.06. Changes to Stated Amount. At any time when any Tranche 2 Letter of Credit is outstanding, at the request of the respective Tranche 2/3 Borrower, the Issuing Agent will enter into an amendment increasing or reducing the Stated Amount of such Tranche 2 Letter of Credit, provided that (i) in no event shall the Stated Amount of any Tranche 2 Letter of Credit be increased to an amount which would exceed the applicable limitations set forth in Section 3B.01(b); (ii) the Stated Amount of a Tranche 2 Letter of Credit may not be increased at any time if the conditions precedent set forth in Section 5.02 are not satisfied at such time; and (iii) the Stated Amount of a Tranche 2 Letter of Credit may not be increased at any time after the date which is 30 days prior to the Commitment Expiration Date.

The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 10.02) or in the absence of its own gross negligence or 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 the Borrowers or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article V or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

Section 9.04. Reliance. 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 Borrowers), 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.

Section 9.05. Delegation of Duties. The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall

apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Section 9.06. Resignation. Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders and the Borrowers. Upon any such resignation, the Required Lenders shall have the right to appoint a successor administrative agent, with the consent of the Borrowers (not to be unreasonably withheld or delayed), provided that no such consent shall be required at any time when a Default or Event of Default exists. 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, 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 Borrowers to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 10.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

Section 9.07. Non-Reliance. 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 related agreement or any document furnished hereunder or thereunder.

Section 9.08. Documentation Agents. Notwithstanding any other provision of this Agreement or any provision of any other Credit Document, each of the Documentation Agents are named as such for recognition purposes only, and in their respective capacities as such shall have no powers, duties, responsibilities or liabilities with respect to this Agreement or the other Credit Documents or the transactions contemplated hereby and thereby. Without limitation of the foregoing, none of the Documentation Agents shall, solely by reason of this Agreement or any other Credit Documents, have any fiduciary relationship with any Lender or any other Person.

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

(b) Neither this Agreement nor any other Credit Document nor any provision hereof or thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by each Borrower and the Required Lenders or by each Borrower and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or the amount of any Tranche 1 Unpaid Drawing or Tranche 2 Unpaid Drawing or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan or the amount of any Tranche 1 Unpaid Drawing or Tranche 2 Unpaid Drawing or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.17(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) change any of the provisions of this Section or the definition of “Required Lenders” or “Majority Tranche 1 Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender, (vi) release all or substantially all of the security provided by the Designated Subsidiary Borrowers to secure the Tranche 1 Obligations, without the written consent of each Tranche 1 Lender, (vii) modify the definitions in Section 1.01 of “Advance Rates,” “Borrowing Base” or “Eligible Securities” without the consent of the Agents, the Documentation Agents and any additional Lender required to constitute the Majority Tranche 1 Lenders, (viii) modify, change, waive, discharge or terminate any provision of any Security Document without the consent of the Majority Tranche 1 Lenders or (ix) release Intermediate Holdings from the Intermediate Holdings Guaranty without the consent of all Lenders; provided, further, that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent or the Issuing Agent hereunder

without the prior written consent of the Administrative Agent or the Issuing Agent, as the case may be.

Section 10.03. Expenses; Indemnity; Damage Waiver. (a) Each Borrower shall pay, severally in accordance with its respective Facility-wide Liability Percentage and not jointly, (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facility provided for herein, the preparation, negotiation and administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), and (ii) all out-of-pocket expenses incurred by the Administrative Agent, the Collateral Agent, the Custodian, the Issuing Agent or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, or in connection with the Loans and Letters of Credit made hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans.

(b) The Parent Borrower shall indemnify the Administrative Agent, the Collateral Agent, the Custodian, the Issuing Agent and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or any other transactions contemplated hereby, (ii) any Loan, Letter of Credit or the use of the proceeds therefrom, (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Parent Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Parent Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee or any Related Party of such Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and non-appealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or any Related Party of such Indemnitee. Notwithstanding the foregoing, for the sake of clarity, the parties hereto acknowledge and agree that the obligations of the Parent Borrower under this Section 10.03(b) shall not include the payment of principal or interest on the Loans, any Unpaid Drawing in respect of any Letter of Credit, or any amounts payable pursuant to Section 2.11, 2.12, 2.14, 2.15, 2.16 or 10.03(a) of this Agreement.

(c) To the extent that any Borrower fails to pay any amount required to be paid by it to the Administrative Agent, under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim,

damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent, in its capacity as such.

(d) To the extent permitted by applicable law, no Borrower shall assert, and each Borrower 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, any Loan or the use of the proceeds thereof.

(e) All amounts due under this Section shall be payable promptly after written demand therefor.

Section 10.04. Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby except that (i) no Borrower may 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 such Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more banks, investment funds or other institutions that make or hold commercial loans in the ordinary course of their businesses (so long as such bank, fund or institution is an NAIC approved bank or institution) 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) of:

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

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

(C) the Issuing Agent, provided that no consent of the Issuing Agent shall be required for an assignment of any Commitment to an assignee that is a Lender with a Commitment immediately prior to giving effect to such assignment.

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

(A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans of any Tranche, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of the Parent Borrower and the Administrative Agent otherwise consent, provided that no such consent of the Parent Borrower shall be required if an Event of Default under Section 8.01, 8.02 or 8.05 has occurred and is continuing;

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

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

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

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

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

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement (provided that any liability of any Borrower to such assignee under Section 2.14, 2.15 or 2.16 shall be limited to the amount, if any, that would have been payable thereunder by such Borrower in the absence of such assignment, except to the extent any such amounts are attributable to a Change in Law), and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.14, 2.15, 2.16 and 10.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 10.04 shall be treated for purposes of this Agreement

as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

(ii) The Administrative Agent, acting for this purpose as an agent of the Borrowers, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans and other Obligations and 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 Borrowers, the Administrative Agent 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 Borrowers, and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(iii) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided that no such assignment shall become effective until all then outstanding Tranche 1 Letters of Credit and/or Tranche 2 Letters of Credit, as the case may be, shall be returned by each respective beneficiary to the Issuing Agent either for cancellation and/or to be exchanged for new or amended Letters of Credit to reflect such assignment (it being understood that to the extent the respective beneficiaries do not consent to such assignment, such assignment cannot occur). 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 any Borrower or the Administrative Agent, 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 Borrowers, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. 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 10.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.14, 2.15 and 2.16 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the

benefits of Section 10.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.17(c) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.14 or 2.16 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Parent Borrower’s prior written consent and the entitlement to greater payment results solely from a Change in Law. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.16 unless the Parent Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers, to comply with Section 2.16(e) as though it were a Lender.

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

(e) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an, “SPC”) of such Granting Lender, identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Parent Borrower, the option to provide to the applicable Borrower all or any part of any Loan that such Granting Lender would otherwise be obligated to make to such Borrower pursuant to Section 2.01, provided that (i) nothing herein shall constitute a commitment to make any Loan by any SPC 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 the Granting Lender. Each party hereto hereby agrees that (x) no SPC shall be liable for any payment under this Agreement for which a Lender would otherwise be liable and (y) the Granting Lender for any SPC shall be (and hereby agrees that it is) liable for any payment under this Agreement for which the SPC would be liable in the absence of preceding clause (x). In furtherance of the foregoing, each party hereto hereby agrees that, prior to the date that is one year and one day after the payment in full of all outstanding senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings or similar proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section 10.04 any SPC may (i) with notice to, but without the prior written consent of, the Parent Borrower or the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to its Granting Lender or to any financial institutions (if consented to by the Parent Borrower and the Administrative Agent) providing liquidity and/or credit facilities to or for the account of such SPC to fund the Loans made by such SPC or to support the securities (if any) issued by such SPC to fund such Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of a surety, guarantee or credit or liquidity enhancement to such SPC.

Section 10.05. Survival. All covenants, agreements, representations and warranties made by each Credit Party herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of Letters of Credit regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent 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 any Letter of Credit is outstanding, 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 and so long as the Total Commitments have not expired or terminated. The provisions of Sections 2.14, 2.15, 2.16 and 10.03 and Article IX shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Total Commitments or the termination of this Agreement or any provision hereof.

Section 10.06. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 5.01, 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 telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

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

Section 10.08. Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of any Credit Party against any of and all the obligations of such Credit Party now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

101

Section 10.09. Governing Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in accordance with and governed by the law of the State of New York (without giving regard to any conflict of laws principles thereof).

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

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

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

Section 10.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Each of the Administrative Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that (i) 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 in accordance with the terms of this Agreement and (ii) that the Administrative Agent and each Lender shall be responsible for any breach of this Section 10.12 by any of its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors), (b) to the extent requested by any regulatory authority or self-regulatory body, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to any Credit Party and its obligations, (g) with the consent of the Parent Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, or any Lender on a nonconfidential basis from a source other than the Credit Parties. For the purposes of this Section, “Information” means all information received from any Credit Party relating to the Parent Borrower or any Subsidiary of the Parent Borrower or their respective businesses, other than any such information that is available to the Administrative Agent, or any Lender on a nonconfidential basis prior to disclosure by any Credit Party. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information or, in the case of any Lender, such Lender has treated such Information in a manner consistent with banking industry standards for the treatment of confidential information. Notwithstanding anything herein to the contrary, each party to this Agreement (and any employee, representative or other agent of each such party) may disclose to any and all persons, without limitation of any kind, the U.S. federal income tax treatment and the U.S. federal income tax structure of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to it relating to such tax treatment and tax structure. However, no disclosure of any information relating to such tax treatment or tax structure may be made to the extent nondisclosure is reasonably necessary in order to comply with applicable securities laws. The provisions of this Section 10.12 shall survive the termination of the Total Commitments and repayment of the Loans and other Obligations hereunder.

Section 10.13. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and,

103

to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

Section 10.14. Judgment Currency. (a) Each Borrower’s obligations hereunder and under the other Credit Documents to make payments in Dollars (the “Obligation Currency”) shall not be discharged or satisfied by any tender or recovery pursuant to any judgment expressed in or converted into any currency other than the Obligation Currency, except to the extent that such tender or recovery results in the effective receipt by the Administrative Agent or the respective Lender of the full amount of the Obligation Currency expressed to be payable to the Administrative Agent or such Lender under this Agreement or the other Credit Documents. If, for the purpose of obtaining or enforcing judgment against any Borrower in any court or in any jurisdiction, it becomes necessary to convert into or from any currency other than the Obligation Currency (such other currency being hereinafter referred to as the “Judgment Currency”) an amount due in the Obligation Currency, the conversion shall be made based on the respective spot exchange rate as quoted by the Administrative Agent as of 11:00 a.m. (London time) on the Business Day immediately preceding the day on which the judgment is given (such Business Day being hereinafter referred to as the “Judgment Currency Conversion Date”).

(b) If there is a change in the rate of exchange prevailing between the Judgment Currency Conversion Date and the date of actual payment of the amount due, each Borrower covenants and agrees to pay, or cause to be paid, such additional amounts, if any (but in any event not a lesser amount) as may be necessary to ensure that the amount paid in the Judgment Currency, when converted at the rate of exchange prevailing on the date of payment, will produce the amount of the Obligation Currency which could have been purchased with the amount of Judgment Currency stipulated in the judgment or judicial award at the rate of exchange prevailing on the Judgment Currency Conversion Date.

(c) For purposes of determining any rate of exchange for this Section, such amounts shall include any premium and costs payable in connection with the purchase of the Obligation Currency.

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

ARTICLE XI

Intermediate Holdings Guaranty

Section 11.01. The Guaranty. In order to induce the Lenders to enter into this Agreement and to extend credit hereunder and in recognition of the direct benefits to be received by Intermediate Holdings from the proceeds of the Loans to be incurred by the Guaranteed Parties and the issuance of the Letters of Credit for the account of the Guaranteed Parties, Intermediate Holdings hereby agrees with the Lenders as follows: Intermediate Holdings hereby unconditionally and irrevocably guarantees, as primary obligor and not merely as surety, the full and prompt payment when due, whether upon maturity, acceleration or otherwise, of any and all of the Guaranteed Obligations of each Guaranteed Party to the Guaranteed Creditors. If any or all of the Guaranteed Obligations of any Guaranteed Party to the Guaranteed Creditors becomes due and payable hereunder, Intermediate Holdings unconditionally promises to pay such indebtedness to the Guaranteed Creditors, or order, on demand, together with any and all expenses which may be incurred by the Guaranteed Creditors in collecting any of the Guaranteed Obligations. This Intermediate Holdings Guaranty is a guaranty of payment and not of collection. If a claim is ever made upon any Guaranteed Creditor for repayment or recovery of any amount or amounts received in payment or on account of any of the Guaranteed Obligations and any of the aforesaid payees repays all or part of said amount by reason of (i) any judgment, decree or order of any court or administrative body having jurisdiction over such payee or any of its property or (ii) any settlement or compromise of any such claim effected by such payee with any such claimant, then and in such event Intermediate Holdings agrees that any such judgment, decree, order, settlement or compromise shall be binding upon Intermediate Holdings, notwithstanding any revocation of this Intermediate Holdings Guaranty or any other instrument evidencing any liability of any Guaranteed Party, and Intermediate Holdings shall be and remain liable to the aforesaid payees hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by any such payee.

Section 11.02. Bankruptcy. Additionally, Intermediate Holdings unconditionally and irrevocably guarantees the payment of any and all of the Guaranteed Obligations of each Guaranteed Party hereunder to the Guaranteed Creditors whether or not due or payable by any Guaranteed Party upon the occurrence of any of the events specified in Section 8.05 with respect to such Guaranteed Party, and unconditionally promises to pay such indebtedness to the Guaranteed Creditors, or order, on demand, in lawful money of the United States.

Section 11.03. Nature of Liability. The liability of Intermediate Holdings hereunder is exclusive and independent of any security for or other guaranty of the Guaranteed Obligations of any Guaranteed Party whether executed by Intermediate Holdings, any other guarantor or by any other party, and the liability of Intermediate Holdings hereunder is not affected or impaired by (a) any direction as to application of payment by each Guaranteed Party or by any other party (other than a direction by the Guaranteed Creditor receiving such payment), or (b) any other continuing or other guaranty, undertaking or maximum liability of a guarantor or of any other party as to the Guaranteed Obligations of each Guaranteed Party, or (c) any payment on or in reduction of any such other guaranty or undertaking, or (d) any dissolution, termination or increase, decrease or change in personnel by any Guaranteed Party, or (e) any payment made

105

to the Guaranteed Creditors on the Guaranteed Obligations which any such Guaranteed Creditor repays to any Guaranteed Party pursuant to court order in any bankruptcy, reorganization, arrangement, moratorium or other debtor relief proceeding, and Intermediate Holdings waives any right to the deferral or modification of its obligations hereunder by reason of any such proceeding or (f) any action or inaction of the type described in Section 11.05.

Section 11.04. Independent Obligation. The obligations of Intermediate Holdings under this Article XI are independent of the obligations of any other guarantor, any other party or any Guaranteed Party, and a separate action or actions may be brought and prosecuted against Intermediate Holdings whether or not action is brought against any other guarantor, any other party or any Guaranteed Party and whether or not any other guarantor, any other party or any Guaranteed Party be joined in any such action or actions. Intermediate Holdings waives, to the full extent permitted by law, the benefit of any statute of limitations affecting its liability under this Article XI or the enforcement thereof. Any payment by any Guaranteed Party or other circumstance which operates to toll any statute of limitations as to any Guaranteed Party shall operate to toll the statute of limitations as to Intermediate Holdings.

Section 11.05. Authorization. The obligations of Intermediate Holdings under this Article XI shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by any action taken by any Guaranteed Creditor to:

(a) change the manner, place or terms of payment of, and/or change or extend the time of payment of, renew, increase, accelerate or alter, any of the Guaranteed Obligations (including any increase or decrease in the rate of interest thereon), any security therefor, or any liability incurred directly or indirectly in respect thereof, and the Guaranty herein made shall apply to the Guaranteed Obligations as so changed, extended, renewed or altered;

(b) take and hold security for the payment of the Guaranteed Obligations and sell, exchange, release, impair, surrender, realize upon or otherwise deal with in any manner and in any order any property by whomsoever at any time pledged or mortgaged to secure, or howsoever securing, the Guaranteed Obligations or any liabilities (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and/or any offset there against;

(c) exercise or refrain from exercising any rights against any Guaranteed Party or others or otherwise act or refrain from acting;

(d) release or substitute any one or more endorsers, guarantors, any Guaranteed Party or other obligors;

(e) settle or compromise any of the Guaranteed Obligations, any security therefor or any liability (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any liability (whether due or not) of any Guaranteed Party to its creditors other than the Guaranteed Creditors;

106

(f) apply any sums by whomsoever paid or howsoever realized to any liability or liabilities of any Guaranteed Party to the Guaranteed Creditors regardless of what liability or liabilities of any Guaranteed Party remain unpaid;

(g) consent to or waive any breach of, or any act, omission or default under, this Agreement or any other Credit Document or any of the instruments or agreements referred to herein or therein, or otherwise amend, modify or supplement this Agreement, any other Credit Document or any of such other instruments or agreements; and/or

(h) take any other action which would, under otherwise applicable principles of common law, give rise to a legal or equitable discharge of Intermediate Holdings from its liabilities under this Intermediate Holdings Guaranty.

Section 11.06. Reliance. It is not necessary for the Guaranteed Creditors to inquire into the capacity or powers of any Guaranteed Party or the officers, directors, partners or agents acting or purporting to act on their behalf, and any Guaranteed Obligations made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder.

Section 11.07. Subordination. Any indebtedness of any Guaranteed Party now or hereafter owing to Intermediate Holdings is hereby subordinated to Guaranteed Obligations of any Guaranteed Party owing to the Guaranteed Creditors; and if the Administrative Agent so requests at a time when an Event of Default exists, no Guaranteed Party shall make, or be permitted to make, any payment to Intermediate Holdings in respect of such indebtedness owed to Intermediate Holdings, but without affecting or impairing in any manner the liability of Intermediate Holdings under the other provisions of this Intermediate Holdings Guaranty. Prior to the transfer by Intermediate Holdings of any note or negotiable instrument evidencing any of the indebtedness of any Guaranteed Party to Intermediate Holdings, Intermediate Holdings shall mark such note or negotiable instrument with a legend that the same is subject to this subordination. Without limiting the generality of the foregoing, Intermediate Holdings hereby agrees with the Guaranteed Creditors that it will not exercise any right of subrogation which it may at any time otherwise have as a result of this Intermediate Holdings Guaranty (whether contractual, under Section 509 of the Bankruptcy Code or otherwise) until all Guaranteed Obligations have been irrevocably paid in full in cash.

Section 11.08. Waiver. (a) Intermediate Holdings waives any right (except as shall be required by applicable statute and cannot be waived) to require any Guaranteed Creditor to (i) proceed against each Guaranteed Party, any other guarantor or any other party, (ii) proceed against or exhaust any security held from any Guaranteed Party, any other guarantor or any other party or (iii) pursue any other remedy in any Guaranteed Creditor’s power whatsoever. Intermediate Holdings waives any defense based on or arising out of any defense of any Guaranteed Party, any other guarantor or any other party, other than payment in full of the Guaranteed Obligations, based on or arising out of the disability of each Guaranteed Party, any other guarantor or any other party, or the unenforceability of the Guaranteed Obligations or any part thereof from any cause, or the cessation from any cause of the liability of any Guaranteed Party other than payment in full of the Guaranteed Obligations. The Guaranteed Creditors may, at their election, foreclose on any security held by the Administrative Agent or any other Guaranteed Creditor by one or more judicial or nonjudicial sales, whether or not every aspect of

107

any such sale is commercially reasonable (to the extent such sale is permitted by applicable law), or exercise any other right or remedy the Guaranteed Creditors may have against any Guaranteed Party or any other party, or any security, without affecting or impairing in any way the liability of the Intermediate Holdings hereunder except to the extent the Guaranteed Obligations have been paid. Intermediate Holdings waives any defense arising out of any such election by the Guaranteed Creditors, even though such election operates to impair or extinguish any right of reimbursement or subrogation or other right or remedy of Intermediate Holdings against any Guaranteed Party or any other party or any security.

(b) Intermediate Holdings waives all presentments, demands for performance, protests and notices, including, without limitation, notices of nonperformance, notices of protest, notices of dishonor, notices of acceptance of this Intermediate Holdings Guaranty, and notices of the existence, creation or incurring of new or additional Guaranteed Obligations. Intermediate Holdings assumes all responsibility for being and keeping itself informed of each Guaranteed Party’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks which Intermediate Holdings assumes and incurs hereunder, and agrees that the Guaranteed Creditors shall have no duty to advise the Intermediate Holdings of information known to them regarding such circumstances or risks.

(c) Intermediate Holdings warrants and agrees that each of the waivers set forth above in this Article XI is made with full knowledge of its significance and consequences, and such waivers shall be effective to the maximum extent permitted by law.
