Upon receipt of any such notice, the Administrative Agent shall promptly notify each Lender thereof.

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

2.14 Limitations on Eurodollar Tranches. Notwithstanding anything to the contrary in this Agreement, all borrowings, conversions and continuations of Eurodollar Loans and all selections of Interest Periods shall be in such amounts and be made pursuant to such elections so that, (a) after giving effect thereto, the aggregate principal amount of the Eurodollar Loans comprising each Eurodollar Tranche shall be equal to $1,000,000 or a whole multiple of $100,000 in excess thereof, and (b) no more than seven (7) Eurodollar Tranches shall be outstanding at any one time.

2.15 Interest Rates and Payment Dates.

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

(b) Each ABR Loan (including any Swingline Loan) shall bear interest at a rate per annum equal to (i) the ABR plus (ii) the Applicable Margin for ABR Loans.

(c) During the continuance of an Event of Default, at the request of the Required Lenders, all outstanding Loans shall bear interest at a rate per annum equal to the rate that would otherwise be applicable thereto pursuant to the foregoing provisions of this Section plus 2.00% (the “Default Rate”); provided that the Default Rate shall apply to all outstanding Loans automatically and without any Required Lender consent therefor upon the occurrence of any Event of Default arising under Section 8.1(a) or (f).

(d) Interest on the outstanding principal amount of each Loan shall be payable in arrears on each Interest Payment Date; provided that interest accruing pursuant to Section 2.15(c) shall be payable from time to time on demand.

2.16 Computation of Interest and Fees.

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

(b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrower, deliver to the Borrower a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to Section 2.16(a).

2.17 Inability to Determine Interest Rate. If prior to the first day of any Interest Period, the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower) in connection with any request for a Eurodollar Loan or a conversion to or a continuation thereof that, by reason of circumstances affecting the relevant market or the Eurodollar Rate is otherwise unavailable, (a) Dollar deposits are not being offered to banks in the London interbank market for the applicable amount and Interest Period of such requested Loan or conversion or continuation, as applicable, (b) adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or (c) the Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Loans during such Interest Period, then, in any such case (a), (b) or (c), the Administrative Agent shall promptly notify the Borrower and the Lenders thereof as soon as practicable thereafter. Any such determination shall specify the basis for such determination and shall, in the absence of manifest error, be conclusive and binding for all purposes. Thereafter, until such notice has been withdrawn by the Administrative Agent, (x) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as ABR Loans, (y) any Loans that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as ABR Loans and (z) any outstanding Eurodollar Loans shall be converted, on the last day of the then-current Interest Period, to ABR Loans. Until such notice has been withdrawn by the Administrative Agent, no further

Eurodollar Loans shall be made or continued as such, nor shall the Borrower have the right to convert Loans to Eurodollar Loans.

2.18 Pro Rata Treatment and Payments.

(a) Each borrowing by the Borrower from the Lenders hereunder, each payment by the Borrower on account of any commitment fee and any reduction of the Commitments shall be made pro rata according to the respective Revolving Percentages of the Lenders.

(b) [Reserved].

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

(d) Subject to Section 2.20(a), all payments (including prepayments) to be made by the Borrower hereunder, whether on account of principal, interest, fees or otherwise, shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff and shall be made prior to 10:00 A.M. on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Funding Office, in Dollars and in immediately available funds. The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received. Any payment received by the Administrative Agent after 10:00 A.M. shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal pursuant to the preceding two sentences, interest thereon shall be payable at the then applicable rate during such extension.

(e) Unless the Administrative Agent shall have been notified in writing by any Lender prior to the proposed date of any borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such date in accordance with Section 2, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such amount is not in fact made available to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender and the Borrower severally agree to pay to the Administrative Agent forthwith, on demand, such corresponding amount with interest thereon, for each day from and including the date on which such amount is made available to the Borrower but excluding the date of payment to the Administrative Agent, at (i) in the case of a payment to be made by such Lender, a rate equal to the greater of (A) the Federal Funds Effective Rate and (B) a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation, and (ii) in the case of a payment to be made by the Borrower, the rate per annum applicable to ABR Loans. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

(f) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Lender hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Lender, as the case may be, their respective pro rata shares of the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Lender, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing 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. Nothing herein shall be deemed to limit the rights of Administrative Agent or any Lender against the Borrower.

(g) If any Lender makes available to the Administrative Agent funds for any Loan to be made by such Lender as provided in the foregoing provisions of this Section 2, and such funds are not made available to the Borrower by the Administrative Agent because the conditions to the applicable extension of credit set forth in Section 5.1 or Section 5.2 are not satisfied or waived in accordance with the terms hereof, the Administrative Agent shall return such funds (in like funds as received from such Lender) to such Lender, without interest.

(h) The obligations of the Lenders hereunder to (i) make Loans, (ii) to fund its participations in L/C Disbursements in accordance with its respective Revolving Percentage, (iii) to fund its respective Swingline Participation Amount of any Swingline Loan, and (iv) to make payments pursuant to Section 9.7, as applicable, are several and not joint. The failure of any Lender to make any such Loan, to fund any such participation or to make any such payment under Section 9.7 on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan, to purchase its participation or to make its payment under Section 9.7.

(i) Nothing herein shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Loan in any particular place or manner.

(j) 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, toward payment of interest, fees, and Overadvances then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest, fees, and Overadvances then due to such parties, and (ii) second, toward payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties.

(k) If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the principal of or interest on any Loan made by it, its participation in the L/C Exposure or other obligations hereunder, as applicable (other than pursuant to a provision hereof providing for non-pro rata treatment), in excess of its Revolving Percentage of such payment on account of the Loans or participations obtained by all of the Lenders, such Lender shall (a) notify the Administrative Agent of the receipt of such payment, and (b) within five (5) Business Days of such receipt purchase (for cash at face value) from the other Lenders or L/C Lenders, as applicable (through the Administrative Agent), without recourse, such participations in the Loans made by them and/or participations in the L/C Exposure held by them, as applicable, or make such other

adjustments as shall be equitable, as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of the other Lenders in accordance with their respective Revolving Percentages; provided, however, that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest and (ii) the provisions of this paragraph shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender) or (y) any payment obtained by a Lender as consideration for the assignment or sale of a participation in any of its Loans or participations in L/C Disbursements to any assignee or participant, other than to the Borrower or any of its Affiliates (as to which the provisions of this paragraph shall apply). The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.18(k) may exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. No documentation other than notices and the like referred to in this Section 2.18(k) shall be required to implement the terms of this Section 2.18(k). The Administrative Agent shall keep records (which shall be conclusive and binding in the absence of manifest error) of participations purchased pursuant to this Section 2.18(k) and shall in each case notify the Lenders or the L/C Lenders, as applicable, following any such purchase. The provisions of this Section 2.18(k) shall not be construed to apply to (i) any payment made by or on behalf of the Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), (ii) the application of Cash Collateral provided for in Section 3.10, or (iii) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or sub-participations in any L/C Exposure to any assignee or participant, other than an assignment to the Borrower or any Affiliate thereof (as to which the provisions of this Section shall apply). The Borrower consents on behalf of itself and each other Loan Party 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 with respect to an Obligation of the Borrower may exercise against each Loan Party rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of each Loan Party in the amount of such participation. For the avoidance of doubt, no amounts received by the Administrative Agent or any Lender from any Guarantor that is not a Qualified ECP Guarantor shall be applied in partial or complete satisfaction of any Excluded Swap Obligations.

(l) [Reserved].

(m) Notwithstanding anything to the contrary in this Agreement, the Administrative Agent may, in its discretion at any time or from time to time, without the Borrower’s request and even if the conditions set forth in Section 5.2 would not be satisfied, make a Loan to the Borrower in an amount equal to the portion of the Obligations constituting overdue interest and fees and Swingline Loans from time to time due and payable to itself, any Lender, the Swingline Lender or the Issuing Lender, and apply the proceeds of any such Loan to those Obligations; provided that after giving effect to any such Loan, the Total Revolving Extensions of Credit will not exceed the Total Commitments.

2.19 Illegality; Requirements of Law.

(a) Illegality. If any Lender determines that any Requirement of Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for such Lender to make, maintain or fund Eurodollar Loans, or to determine or charge interest rates based upon the Eurodollar Rate, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the London interbank market, then, on notice thereof by such Lender to the Borrower through the Administrative Agent, any obligation of such Lender to make or

continue Eurodollar Loans, or to convert ABR Loans to Eurodollar Loans shall be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all Eurodollar Loans of such Lender to ABR Loans, either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Eurodollar Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Loans. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted.

(b) Requirements of Law. If the adoption of or any change in any Requirement of Law or in the administration, interpretation, implementation or application thereof by any Governmental Authority, or the making or issuance of any request, rule, guideline or directive (whether or not having the force of law) by any Governmental Authority made subsequent to the date hereof:

(i) shall subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes, and (C) Connection Income Taxes) on its Loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto;

(ii) shall impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of or credit extended or participated in by, any Lender (except any reserve requirement reflected in the Eurodollar Rate); or

(iii) impose on any Lender or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, converting to, continuing or maintaining Loans determined with reference to the Eurodollar Rate or of maintaining its obligation to make such Loans, or to increase the cost to such Lender or such other Recipient of issuing, maintaining or participating in Letters of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum receivable or received by such Lender or other Recipient hereunder in respect thereof (whether of principal, interest or any other amount), then, in any such case, upon the request of such Lender or other Recipient, the Borrower will promptly pay such Lender or other Recipient, as the case may be, any additional amount or amounts necessary to compensate such Lender or other Recipient, as the case may be, for such additional costs incurred or reduction suffered. If any Lender becomes entitled to claim any additional amounts pursuant to this paragraph, it shall promptly notify the Borrower (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled.

(c) If any Lender determines that any change in any Requirement of Law affecting such Lender or any lending office of such Lender or such Lender’s holding company, if any, regarding capital or liquidity 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, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit or Swingline Loans held by, such Lender, or the Letters of Credit issued by the Issuing Lender, to a level below that which such Lender or such Lender’s holding company could have achieved but for such change in such Requirement of Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy and liquidity), then from time to time the Borrower will pay to such Lender or the Issuing Lender, as the case may be, such additional amount

or amounts as will compensate such Lender or the Issuing Lender or such Lender’s or Issuing Lender’s holding company for any such reduction suffered.

(d) For purposes of this Agreement, (i) the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, guidelines, or directives thereunder or issued in connection therewith and (ii) all requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel III, shall in each case (i) and (ii) be deemed to be a change in any Requirement of Law, regardless of the date enacted, adopted or issued.

(e) A certificate as to any additional amounts payable pursuant to paragraphs (b), (c), or (d) of this Section submitted by any Lender to the Borrower (with a copy to the Administrative Agent), including in reasonable detail a description of the basis for such claim and an explanation of how such amounts were determined, shall be conclusive in the absence of manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. 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. Notwithstanding anything to the contrary in this Section 2.19, the Borrower shall not be required to compensate a Lender or Issuing Lender pursuant to this Section 2.19 for any amounts incurred or reductions suffered more than nine months prior to the date that such Lender or Issuing Lender, as the case may be, notifies the Borrower of the change in the Requirement of Law giving rise to such increased costs or reductions, and of such Lender’s or Issuing Lender’s intention to claim compensation therefor; provided that if the circumstances giving rise to such claim have a retroactive effect, then such nine-month period shall be extended to include the period of such retroactive effect. The obligations of the Borrower arising pursuant to this Section 2.19 shall survive the Discharge of Obligations and the resignation of the Administrative Agent.

2.20 Taxes.

For purposes of this Section 2.20, the term “Lender” includes the Issuing Lender and the term “applicable law” includes FATCA.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law, and the Borrower shall, and shall cause each other Loan Party to, comply with the requirements set forth in this Section 2.20. If any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Loan Party shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings for Indemnified Tax applicable to additional sums payable under this Section 2.20) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding for Indemnified Tax been made.

(b) Payment of Other Taxes. The Borrower shall, and shall cause each other Loan Party to, timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes applicable to such Loan Party.

(c) Evidence of Payments. As soon as practicable after any payment of Taxes by any Loan Party to a Governmental Authority pursuant to this Section 2.20, the Borrower shall, or shall cause such other Loan Party to, 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.

(d) Indemnification by Loan Parties. The Borrower shall, and shall cause each other Loan Party to, jointly and severally indemnify each Recipient, within ten (10) days after written demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 2.20(d) (but without duplication of any amounts compensated for by another provision of this Agreement or any other Loan Document) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto (excluding any amount of value added Tax which is recovered by such Recipient) (including any recording and filing fees with respect thereto or resulting therefrom and any interest, penalties or similar liabilities imposed by the applicable Governmental Authority with respect to, or resulting from, any delay in paying such Indemnified Taxes), whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability, including in reasonable detail a description of the basis for such payment or liability and an explanation of how the amount of such payment or liability was determined, delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e) Indemnification by Lenders. Each Lender shall severally indemnify the Administrative Agent, within ten (10) days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that any Loan Party has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Loan Parties to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 10.6 relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such 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 any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this Section 2.20(e).

(f) Status of Lenders.

(i) Any Lender (including, solely for purposes of this Section 2.20(f), the Administrative Agent) that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and

submission of such documentation (other than such documentation set forth in Sections 2.20(f)(ii)(A), (ii)(B), or (ii)(D) below) shall not be required if, in the Lender’s reasonable judgment, such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii) Without limiting the generality of the foregoing, in the event that the Borrower is a U.S. Person,

(A) any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), properly completed, valid and executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable:

(1) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, properly completed, valid and executed originals of IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable (or any successor form) establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, properly completed, valid and executed originals of IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable (or any successor form) establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(2) properly completed, valid and executed originals of IRS Form W-8ECI (or any successor form);

(3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit F-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) properly completed, valid and executed originals of IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable (or any successor form); or

(4) to the extent a Foreign Lender is not the beneficial owner, properly completed, valid and executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable (or any successor form), a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-2 or Exhibit F-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of

such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-4 on behalf of each such direct and indirect partner;

(C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), valid executed copies of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and

(D) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(iii) [Reserved],

(iv) Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so. Each Foreign Lender shall promptly notify the Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of certification adopted by the U.S. taxing authorities for such purpose). Notwithstanding any other provision of this paragraph, a Foreign Lender shall not be required to deliver any form pursuant to this paragraph that such Foreign Lender is not legally able to deliver.

(g) [Reserved].

(h) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.20 (including by the payment of additional amounts pursuant to this Section 2.20), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund).

Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this Section 2.20(h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 2.20(h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 2.20(h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(i) Survival. Each party’s obligations under this Section 2.20 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender and the Discharge of Obligations.

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

2.22 Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.19(b), Section 2.19(c), Section 2.20(a), Section 2.20(b) or Section 2.20(d) with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate a different lending office for funding or booking its Loans affected by such event 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 2.19 or 2.20, 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; provided that nothing in this Section shall affect or postpone any of the obligations of the Borrower or the rights of any Lender pursuant to Section 2.19(b), Section 2.19(c), Section 2.20(a), Section 2.20(b) or Section 2.20(d). The Borrower hereby agrees to pay all reasonable and documented costs and expenses incurred by any Lender in connection with any such designation or assignment made at the request of the Borrower.

2.23 Substitution of Lenders. Upon the receipt by the Borrower of any of the following (or in the case of clause (a) below, if the Borrower is required to pay any such amount, regardless of whether the Lender makes a request for such payment), with respect to any Lender (any such Lender described in clauses (a) through (c) below being referred to as an “Affected Lender” hereunder):

(a) a request from a Lender for payment of Indemnified Taxes or additional amounts under Section 2.20 or of increased costs pursuant to Section 2.19(b) or Section 2.19(c);

(b) a notice from the Administrative Agent under Section 10.1(b) that one or more Minority Lenders are unwilling to agree to an amendment or other modification approved by the Required Lenders and the Administrative Agent; or

then the Borrower may, at its sole expense and effort, upon notice to the Administrative Agent and such Affected Lender: (i) request that one or more of the other Lenders acquire and assume all or part of such Affected Lender’s Loans, Commitment and all other Obligations owing to such Affected Lender; or (ii) designate a replacement lending institution (which shall be an Eligible Assignee) to acquire and assume all or a ratable part of such Affected Lender’s Loans, Commitment and all other Obligations owing to such Affected Lender (the replacing Lender or lender in (i) or (ii) being a “Replacement Lender”); provided, however, that the Borrower shall be liable for the payment upon demand of all costs and other amounts arising under Section 2.21 that result from the acquisition of any Affected Lender’s Loan and/or Commitment (or any portion thereof) by a Lender or Replacement Lender, as the case may be, on a date other than the last day of the applicable Interest Period with respect to any Eurodollar Loans then outstanding. The Affected Lender replaced pursuant to this Section 2.23 shall be required to assign and delegate, without recourse, all of its interests, rights and obligations under this Agreement and the related Loan Documents to one or more Replacement Lenders that so agree to acquire and assume all or a ratable part of such Affected Lender’s Loans, Commitment and all other Obligations owing to such Affected Lender upon payment to such Affected Lender of an amount (in the aggregate for all Replacement Lenders) equal to 100% of the outstanding principal of the Affected Lender’s Loans, accrued interest thereon, accrued fees and all other Obligations payable to it hereunder and under the other Loan Documents from such Replacement Lenders (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts, including amounts under Section 2.21 hereof). Any such designation of a Replacement Lender shall be effected in accordance with, and subject to the terms and conditions of, the assignment provisions contained in Section 10.6 (with the assignment fee to be paid by the Borrower in such instance); provided that, if such Affected Lender does not comply with Section 10.6 within ten Business Days after the Borrower’s request, compliance with Section 10.6 shall not be required to effect such assignment, and, if such Replacement Lender is not already a Lender hereunder or an Affiliate of a Lender or an Approved Fund, shall be subject to the prior written consent of the Administrative Agent (which consent shall not be unreasonably withheld or delayed). Notwithstanding the foregoing, with respect to any assignment pursuant to this Section 2.23, (a) in the case of any such assignment resulting from a claim for compensation under Section 2.19 or payments required to be made pursuant to Section 2.20, such assignment shall result in a reduction in such compensation or payments thereafter; (b) such assignment shall not conflict with applicable law and (c) in the case of any assignment resulting from a Lender being a Minority Lender referred to in clause (b) of this Section 2.23, the applicable assignee shall have consented to the applicable amendment, waiver or consent. Notwithstanding the foregoing, an Affected Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Affected Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

2.24 Defaulting Lenders.

(a) Defaulting Lender Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

(i) Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in Section 10.1 and in the definition of Required Lenders.

(ii) Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Section 8 or otherwise, and including any amounts made available to the Administrative Agent by such Defaulting Lender pursuant to Section 10.7), shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the Issuing Lender or to the Swingline Lender hereunder; third, to be held as Cash Collateral for the funding obligations of such Defaulting Lender of any participation in any Letter of Credit; fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrower, to be held in a Deposit Account and released pro rata to (x) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement, and (y) be held as Cash Collateral for the future funding obligations of such Defaulting Lender of any participation in any future Letter of Credit; sixth, to the payment of any amounts owing to any L/C Lender, Issuing Lender or Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any L/C Lender, Issuing Lender or Swingline Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default has occurred and is continuing, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (A) such payment is a payment of the principal amount of any Loans or L/C Advances in respect of which such Defaulting Lender has not fully funded its appropriate share and (B) such Loans or L/C Advances were made at a time when the conditions set forth in Section 5.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and L/C Advances owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or L/C Advances owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in L/C Advances and Swingline Loans are held by the Lenders pro rata in accordance with the Commitments without giving effect to Section 2.24(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.24(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees.

(A) No Defaulting Lender shall be entitled to receive any fee pursuant to Section 2.9(b) for any period during which such Lender is a Defaulting Lender (and

the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to such Defaulting Lender).

(B) Each Defaulting Lender shall be limited in its right to receive letter of credit fees as provided in Section 3.3(d).

(C) With respect to any letter of credit fee not required to be paid to any Defaulting Lender pursuant to clause (A) or (B) above, the Borrower shall (x) pay to each Non-Defaulting Lender that portion of any such letter of credit fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in Letters of Credit that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (y) pay to the Issuing Lender the amount of any such letter of credit fee otherwise payable to such Defaulting Lender to the extent allocable to the Issuing Lender’s Fronting Exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such letter of credit fee.

(iv) Reallocation of Pro Rata Share to Reduce Fronting Exposure. During any period in which there is a Defaulting Lender, for purposes of computing the amount of the obligation of each Non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit pursuant to Section 3.4 or in Swingline Loans pursuant to Section 2.7(c), the Revolving Percentage of each Non-Defaulting Lender of any such Letter of Credit and the Revolving Percentage of each Non-Defaulting Lender of any such Swingline Loan, as the case may be, shall be computed without giving effect to the applicable Commitment of such Defaulting Lender; provided that, (A) each such reallocation shall be given effect only if, at the date of such reallocation, no Event of Default has occurred and is continuing; and (B) the aggregate obligations of each Non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit and Swingline Loans shall not exceed the positive difference, if any, of (1) the Commitment of such Non-Defaulting Lender minus (2) such Non-Defaulting Lender’s Revolving Percentage of the Total Revolving Extensions of Credit. Subject to Section 10.21, no reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation.

(v) Cash Collateral, Repayment of Swingline Loans. If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under law, (x) first, prepay Swingline Loans in an amount equal to the Swingline Lender’s Fronting Exposure and (y) second, Cash Collateralize the Issuing Lender’s Fronting Exposure in accordance with the procedures set forth in Section 3.10.

(b) Defaulting Lender Cure. If the Borrower, the Administrative Agent, the Swingline Lender and the Issuing Lender agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), such Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit and Swingline Loans to be held on a pro rata basis by the Lenders in accordance with their respective Revolving Percentages (without giving effect to Section 2.24(a)(iv)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while such Lender was a Defaulting Lender;

and provided further that, except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender having been a Defaulting Lender.

(c) New Swingline Loans/Letters of Credit. So long as any Lender is a Defaulting Lender, (i) the Swingline Lender shall not be required to fund any Swingline Loans unless it is satisfied that it will have no Fronting Exposure after giving effect to such Swingline Loan, and (ii) the Issuing Lender shall not be required to issue, extend, renew or increase any Letter of Credit unless it is satisfied that it will have no Fronting Exposure in respect of Letters of Credit after giving effect thereto.

(d) Termination of Defaulting Lender. The Borrower may terminate the unused amount of the Commitment of any Lender that is a Defaulting Lender upon not less than ten Business Days’ prior notice to the Administrative Agent (which shall promptly notify the Lenders thereof), and in such event the provisions of Section 2.24(a)(ii) will apply to all amounts thereafter paid by the Borrower for the account of such Defaulting Lender under this Agreement (whether on account of principal, interest, fees, indemnity or other amounts); provided that (i) on the date of such termination, no Event of Default shall have occurred and be continuing, and (ii) such termination shall not be deemed to be a waiver or release of any claim the Borrower, the Administrative Agent, the Issuing Lender, the Swingline Lender or any other Lender may have against such Defaulting Lender.

2.25 Joint and Several Liability. To the extent that any Loan Party shall, under this Agreement and the other Loan Documents as a joint and several obligor, repay any of the Obligations made to another Loan Party hereunder or other Obligations incurred directly and primarily by any other Loan Party (an “Accommodation Payment”), then the Loan Party making such Accommodation Payment shall be entitled to contribution and indemnification from, and be reimbursed by, each other Loan Party that is a joint and several obligor in respect of the Obligations in an amount, for each of such other Loan Party, equal to a fraction of such Accommodation Payment, the numerator of which fraction is such other Loan Party’s Allocable Amount and the denominator of which is the sum of the Allocable Amounts of all of the Loan Parties. As of any date of determination, the “Allocable Amount” of each Loan Party shall be equal to the maximum amount of liability for Accommodation Payments which could be asserted against such Loan Party hereunder without (a) rendering such Loan Party “insolvent” within the meaning of Section 101(31) of the Bankruptcy Code, Section 2 of the Uniform Fraudulent Transfer Act (“UFTA”) or Section 2 of the Uniform Fraudulent Conveyance Act (“UFCA”), (b) leaving such Loan Party with unreasonably small capital or assets, within the meaning of Section 548 of the Bankruptcy Code, Section 4 of the UFTA, or Section 5 of the UFCA, or (c) leaving such Loan Party unable to pay its debts as they become due within the meaning of Section 548 of the Bankruptcy Code or Section 4 of the UFTA, or Section 5 of the UFCA.

2.26 Notes. If so requested by any Lender by written notice to the Borrower (with a copy to the Administrative Agent), the Borrower shall execute and deliver to such Lender (and/or, if applicable and if so specified in such notice, to any Person who is an assignee of such Lender pursuant to Section 10.6) (promptly after the Borrower’s receipt of such notice) a Note or Notes to evidence such Lender’s Loans.

2.27 Incremental Facility.

(a) At any time after the Closing Date during the Commitment Period, the Borrower may request from time to time from one or more existing Lenders or from other Eligible Assignees reasonably acceptable to the Administrative Agent, the Issuing Lender, the Swingline Lender and the Borrower (but subject to the conditions set forth in clause (b) below) the Total Commitments be increased by an amount not to exceed the Available Revolving Increase Amount at such time (each such increase,

an “Increase”); provided that the Borrower may not request an Increase on more than three occasions (excluding any request for an Increase that is not effectuated) during the term of this Agreement. No Lender shall be obligated to increase its Commitments in connection with a proposed Increase. To the extent sufficient existing Lenders, as applicable, do not agree to increase their Commitments on terms acceptable to the Borrower, or to the extent such Lenders have not promptly responded to the Borrower’s request for such increase, the Borrower may invite any prospective lender that satisfies the criteria of being an “Eligible Assignee” to become a Lender pursuant to a joinder agreement in connection with the proposed Increase (provided that the joinder of any such “Lender” for the purpose of providing all or any portion of any such Increase shall require the consent (not to be unreasonably withheld or delayed) of Administrative Agent, the Issuing Lender and the Swingline Lender (but not any other Lender). Any Increase shall be in an amount of at least $10,000,000 (or, if the Available Revolving Increase Amount is less than $10,000,000, such remaining Available Revolving Increase Amount) and integral multiples of $1,000,000 in excess thereof. Additionally, for the avoidance of doubt, it is understood and agreed that in no event shall the aggregate amount of the Increases to the Commitments exceed the Available Revolving Increase Amount during the term of the Agreement.

(b) Each of the following shall be conditions precedent to any Increase of the Commitments in connection therewith:

(i) any Increase shall be on the same terms (including the pricing, and maturity date), as applicable, as, and pursuant to documentation applicable to, the Facility then in effect;

(ii) the Borrower shall have delivered an irrevocable written request to the Administrative Agent for such Increase at least ten (10) Business Days prior to the requested funding date of such Increase;

(iii) [reserved];

(iv) each Lender (including any prospective lenders agreeing to become a Lender hereunder) agreeing to such Increase, the Borrower and the Administrative Agent have signed an Increase Joinder (any Increase Joinder may, with the consent of the Administrative Agent, the Borrower and the Lenders agreeing to such Increase, effect such amendments to this Agreement and the other Loan Documents as may be necessary or appropriate to effectuate the provisions of this Section 2.27) and the Borrower shall have executed any Notes requested by any Lender in connection with the making of the Increase. Notwithstanding anything to the contrary in this Agreement or in any other Loan Document, an Increase Joinder reasonably satisfactory to the Administrative Agent, and the amendments to this Agreement effected thereby, shall not require the consent of any Lender other than the Lender(s) agreeing to fund such Increase;

(v) each of the conditions precedent set forth in Section 5.2(a) and (e) are satisfied with respect to such Increase;

(vi) after giving pro forma effect to such Increase and the use of proceeds thereof and assuming that the Total Commitments are fully drawn, (A) no Default or Event of Default shall have occurred and be continuing at the time of such Increase and (B) the Borrower shall be in compliance with the then applicable financial covenants set forth in Section 7.1 hereof as of the end of the most recently ended quarter for which financial statements are required to be delivered prior to such Increase (provided that the Consolidated Leverage Ratio shall not be greater than 0.25x less than the covenant set forth in Section 7.1(c) for such period), and the Borrower shall have delivered to the Administrative Agent a certificate in form and substance reasonably satisfactory to the Administrative Agent evidencing compliance with the requirements of this clause (vi) and clause (v) above;

(vii) in connection with such Increase, the Borrower shall pay to Administrative Agent all fees required to be paid pursuant to the terms of the Fee Letter; and

(viii) upon each Increase in accordance with this Section 2.27, all outstanding Loans, participations hereunder in Letters of Credit and participations hereunder in Swingline Loans held by each Lender shall be reallocated among the Lenders (including any newly added Lenders) in accordance with the Lenders’ respective revised Revolving Percentages, pursuant to procedures reasonably determined by the Administrative Agent.

(c) Upon the effectiveness of any Increase, (i) all references in this Agreement and any other Loan Document to the Loans shall be deemed, unless the context otherwise requires, to include such Increase advanced pursuant to this Section 2.27 and (ii) all references in this Agreement and any other Loan Document to the Commitment shall be deemed, unless the context otherwise requires, to include the commitment to advance an amount equal to such Increase pursuant to this Section 2.27.

(d) The Loans and Commitments established pursuant to this Section 2.27 shall constitute Loans and Commitments under, and shall be entitled to all the benefits afforded by, this Agreement and the other Loan Documents, and shall, without limiting the foregoing, benefit equally and ratably from any guarantees and the security interests created by the Loan Documents. The Loan Parties shall take any actions reasonably required by Administrative Agent to ensure and demonstrate that the Liens and security interests granted by the Loan Documents continue to be perfected under the UCC or otherwise after giving effect to the establishment of any such new Commitments, which actions may include re-granting Liens and entering into supplements, amendments, restatements or replacements of the Security Documents and executing and delivering all documents, instruments and legal opinions in connection therewith reasonably requested by the Administrative Agent.

SECTION 3
LETTERS OF CREDIT

3.1 L/C Commitment.

(a) Subject to the terms and conditions hereof, the Issuing Lender agrees to issue letters of credit (“Letters of Credit”) for the account of the Borrower (or, with the consent of the applicable Issuing Lender, any Group Member) on any Business Day during the Letter of Credit Availability Period in such form as may reasonably be approved from time to time by the Issuing Lender; provided that the Issuing Lender shall have no obligation to issue any Letter of Credit if, after giving effect to such issuance, (i) the L/C Exposure would exceed the Total L/C Commitments at such time or the Available Commitments would be less than zero at such time, or (ii) an Overadvance would exist at such time. Except as otherwise agreed by the Issuing Lender and the Administrative Agent in their sole discretion, each Letter of Credit shall expire no later than the earlier of (x) the first anniversary of its date of issuance and (y) the Letter of Credit Maturity Date, provided that (i) any Letter of Credit may provide for the renewal thereof for additional one-year periods (which, except as otherwise agreed by the Issuing Lender and the Administrative Agent in their sole discretion, shall in no event extend beyond the date referred to in clause (y) above) and (ii) in the event that the Issuing Lender and the Administrative Agent agree to issue a Letter of Credit with an expiration date that is after the Letter of Credit Maturity Date, such Letter of Credit shall be required to be Cash Collateralized on or prior to the Letter of Credit Maturity Date in an amount equal to 105% of the L/C Exposure attributable to such Letter of Credit in accordance with Section 3.10. Each Letter of Credit shall be denominated in Dollars, or, in the sole discretion of the Issuing Lender with respect to any particular Letter of Credit, an alternative foreign currency. For purposes of this Agreement, the stated amount of any Letter of Credit issued in an

alternative currency shall be converted into Dollars from time to time by the Issuing Lender and upon any drawing under such Letter of Credit.

(b) The Issuing Lender shall not at any time be obligated to issue any Letter of Credit if:

(i) such issuance would conflict with, or cause the Issuing Lender or any L/C Lender to exceed any limits imposed by, any applicable Requirement of Law;

(ii) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain the Issuing Lender from issuing, amending or reinstating such Letter of Credit, or any law, rule or regulation applicable to the Issuing Lender or any request, guideline or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over the Issuing Lender shall prohibit, or request that the Issuing Lender refrain from, the issuance, amendment, renewal or reinstatement of letters of credit generally or such Letter of Credit in particular or shall impose upon the Issuing Lender with respect to such Letter of Credit any restriction, reserve or capital requirement (for which the Issuing Lender is not otherwise compensated) not in effect on the Closing Date, or shall impose upon the Issuing Lender any unreimbursed loss, cost or expense which was not applicable on the Closing Date and which the Issuing Lender in good faith deems material to it;

(iii) the Issuing Lender has received written notice from any Lender, the Administrative Agent or the Borrower, at least one (1) Business Day prior to the requested date of issuance, amendment, renewal or reinstatement of such Letter of Credit, that one or more of the applicable conditions contained in Section 5.2 shall not then be satisfied (which notice shall contain a description of any such condition asserted not to be satisfied);

(iv) any requested Letter of Credit is not in form and substance reasonably acceptable to the Issuing Lender, or the issuance, amendment or renewal of a Letter of Credit shall violate any applicable laws or regulations or any applicable policies of the Issuing Lender;

(v) such Letter of Credit contains any provisions providing for automatic reinstatement of the stated amount after any drawing thereunder;

(vi) except as otherwise agreed by the Administrative Agent and the Issuing Lender, such Letter of Credit is in an initial face amount less than $25,000; or

(vii) any Lender is at that time a Defaulting Lender, unless the Issuing Lender has entered into arrangements, including the delivery of Cash Collateral pursuant to Section 3.10, satisfactory to the Issuing Lender (in its sole discretion) with the Borrower or such Defaulting Lender to eliminate the Issuing Lender’s actual or potential Fronting Exposure (after giving effect to Section 2.24(a)(iv)) with respect to the Defaulting Lender arising from either the Letter of Credit then proposed to be issued or such Letter of Credit and all other L/C Exposure as to which the Issuing Lender has actual or potential Fronting Exposure, as it may elect in its sole discretion.

3.2 Procedure for Issuance of Letters of Credit. The Borrower may from time to time request that the Issuing Lender issue a Letter of Credit for the account of the Borrower (or with the consent of the applicable Issuing Lender, any other Group Member) by delivering to the Issuing Lender at its address for notices specified herein an Application therefor, completed to the satisfaction of the Issuing Lender, and such other certificates, documents and other papers and information as the Issuing Lender may request. Upon receipt of any Application, the Issuing Lender will process such Application and the

certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall promptly issue the Letter of Credit requested thereby (but in no event shall the Issuing Lender be required to issue any Letter of Credit earlier than three (3) Business Days after its receipt of the Application therefor and all such other certificates, documents and other papers and information relating thereto) by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed to by the Issuing Lender and the Borrower. The Issuing Lender shall furnish a copy of such Letter of Credit to the Borrower promptly following the issuance thereof. The Issuing Lender shall promptly furnish to the Administrative Agent, which shall in turn promptly furnish to the Lenders, notice of the issuance of each Letter of Credit (including the amount thereof).

3.3 Fees and Other Charges.

(a) The Borrower agrees to pay, (i) with respect to each outstanding Letter of Credit (including each Existing Letter of Credit), upon the issuance or renewal thereof, a fronting fee of 0.125% of the amount available to be drawn under each such Letter of Credit to the Issuing Lender for its own account (a “Letter of Credit Fronting Fee”), and (ii) with respect to each outstanding Letter of Credit (including each Existing Letter of Credit) a letter of credit fee equal to the Applicable Margin for ABR Loans per annum multiplied by the daily amount available to be drawn under each such Letter of Credit to the Administrative Agent for the ratable account of the L/C Lenders (determined in accordance with their respective Revolving Percentages) (a “Letter of Credit Fee”), payable quarterly in arrears on the last Business Day of each quarter of each year and on the Letter of Credit Maturity Date (each, an “L/C Fee Payment Date”) after the issuance date of such Letter of Credit, and (iii) the Issuing Lender’s standard and reasonable fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder (the fees in this clause (iii), collectively, the “Issuing Lender Fees”). All Letter of Credit Fees shall be computed on the basis of the actual number of days elapsed in a year of 360 days.

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

(c) The Borrower shall furnish to the Issuing Lender and the Administrative Agent such other documents and information pertaining to any requested Letter of Credit issuance, amendment or renewal, including any L/C-Related Documents, as the Issuing Lender or the Administrative Agent may reasonably require. This Agreement shall control in the event of any conflict with any L/C-Related Document (other than any Letter of Credit).

(d) Any letter of credit fees otherwise payable for the account of a Defaulting Lender with respect to any Letter of Credit as to which such Defaulting Lender has not provided Cash Collateral satisfactory to the Issuing Lender pursuant to Section 3.10 shall be payable, to the maximum extent permitted by applicable law, to the other L/C Lenders in accordance with the upward adjustments in their respective Revolving Percentages allocable to such Letter of Credit pursuant to Section 2.23(a)(iv), with the balance of such fee, if any, payable to the Issuing Lender for its own account unless the Borrower has Cash Collateralized such Letter of Credit pursuant to Section 3.10(a).

(e) All fees payable under this Section 3.3 shall be fully earned on the date paid and nonrefundable.

3.4 L/C Participations; Existing Letters of Credit.

(a) L/C Participations. The Issuing Lender irrevocably agrees to grant and hereby grants to each L/C Lender, and, to induce the Issuing Lender to issue Letters of Credit, each L/C Lender irrevocably agrees to accept and purchase and hereby accepts and purchases from the Issuing Lender, on the terms and conditions set forth below, for such L/C Lender’s own account and risk an undivided interest equal to such L/C Lender’s Revolving Percentage in the Issuing Lender’s obligations and rights under and in respect of each Letter of Credit and the amount of each draft paid by the Issuing Lender thereunder. Each L/C Lender agrees with the Issuing Lender that, if a draft is paid under any Letter of Credit for which the Issuing Lender is not reimbursed in full by the Borrower pursuant to Section 3.5(a), such L/C Lender shall pay to the Issuing Lender upon demand at the Issuing Lender’s address for notices specified herein an amount equal to such L/C Lender’s Revolving Percentage of the amount of such draft, or any part thereof, that is not so reimbursed. Each L/C Lender’s obligation to pay such amount shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any setoff, counterclaim, recoupment, defense or other right that such L/C Lender may have against the Issuing Lender, the Borrower or any other Person for any reason whatsoever, (ii) the occurrence of a Default or an Event of Default or the failure to satisfy any of the other conditions specified in Section 5.2, (iii) any adverse change in the condition (financial or otherwise) of the Borrower, (iv) any breach of this Agreement or any other Loan Document by the Borrower, any other Loan Party or any other L/C Lender, or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.

(b) Existing Letters of Credit. On and after the Closing Date, the Existing Letters of Credit shall be deemed for all purposes, including for purposes of the fees to be collected pursuant to Sections 3.3(a)(ii) and 3.3(b), reimbursement of costs and expenses to the extent provided herein and for purposes of being secured by the Collateral, a Letter of Credit outstanding under this Agreement and entitled to the benefits of this Agreement and the other Loan Documents, and shall be governed by the applications and agreements pertaining thereto and by this Agreement (which shall control in the event of a conflict).

3.5 Reimbursement.

(a) If the Issuing Lender shall make any L/C Disbursement in respect of a Letter of Credit, the Issuing Lender shall notify the Borrower and the Administrative Agent thereof and the Borrower shall pay or cause to be paid to the Issuing Lender an amount equal to the entire amount of such L/C Disbursement not later than (i) the immediately following Business Day if the Issuing Lender issues such notice before 10:00 A.M. on the date of such notice or (ii) on the second following Business Day if the Issuing Lender issues such notice on or after 10:00 A.M. on the date of such L/C Disbursement. Each such payment shall be made to the Issuing Lender at its address for notices referred to herein in Dollars and in immediately available funds; provided that the Borrower may request that such payment be financed with a Loan or Swingline Loan in an equivalent amount and, to the extent so financed, the Borrower’s obligations to make such payment shall be discharged and replaced by the resulting Loan or Swingline Loan.

(b) If the Issuing Lender shall not have received from the Borrower the payment that it is required to make pursuant to Section 3.5(a) with respect to a Letter of Credit within the time specified in such Section, the Issuing Lender will promptly notify the Administrative Agent of the L/C Disbursement and the Administrative Agent will promptly notify each L/C Lender of such L/C Disbursement and its Revolving Percentage thereof, and each such L/C Lender shall pay to the Issuing Lender upon demand at the Issuing Lender’s address for notices specified herein an amount equal to such L/C Lender’s Revolving Percentage of such L/C Disbursement (and the Administrative Agent may apply Cash Collateral provided for this purpose); upon such payment pursuant to this paragraph to reimburse the Issuing Lender for any L/C Disbursement, the Borrower shall be required to reimburse the L/C

Lenders for such payments (including interest accrued thereon from the date of such payment until the date of such reimbursement at the rate applicable to Loans that are ABR Loans plus 2% per annum) on demand; provided that if at the time of and after giving effect to such payment by the L/C Lenders, the conditions to borrowings and Loan Conversions set forth in Section 5.2 are satisfied, the Borrower may, by written notice to the Administrative Agent certifying that such conditions are satisfied and that all interest owing under this paragraph has been paid, request that such payments by the L/C Lenders be converted into Loans (a “Loan Conversion”), in which case, if such conditions are in fact satisfied, the L/C Lenders shall be deemed to have extended, and the Borrower shall be deemed to have accepted, a Loan in the aggregate principal amount of such payment without further action on the part of any party; any amount so paid pursuant to this paragraph shall, on and after the payment date thereof, be deemed to be Loans for all purposes hereunder; provided that the Issuing Lender, at its option, may effectuate a Loan Conversion regardless of whether the conditions to borrowings and Loan Conversions set forth in Section 5.2 are satisfied.

3.6 Obligations Absolute. The Borrower’s obligations under this Section 3 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment that the Borrower may have or have had against the Issuing Lender, any beneficiary of a Letter of Credit or any other Person. The Borrower also agrees with the Issuing Lender that the Issuing Lender shall not be responsible for, and the Borrower’s obligations hereunder shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit may be transferred or any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit or any such transferee. The Issuing Lender shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except for errors or omissions found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Issuing Lender. The Borrower agrees that any action taken or omitted by the Issuing Lender under or in connection with any Letter of Credit or the related drafts or documents, if done in the absence of gross negligence or willful misconduct, shall be binding on the Borrower and shall not result in any liability of the Issuing Lender to the Borrower.

In addition to amounts payable as elsewhere provided in the Agreement, the Borrower hereby agrees to pay and to protect, indemnify, and save Issuing Lender harmless from and against any and all claims, demands, liabilities, damages, losses, costs, charges and expenses (including reasonable attorneys’ fees and allocated costs of internal counsel) that the Issuing Lender may incur or be subject to as a consequence, direct or indirect, of (A) the issuance of any Letter of Credit, or (B) the failure of Issuing Lender or of any L/C Lender to honor a demand for payment under any Letter of Credit as a result of any act or omission, whether rightful or wrongful, of any present or future de jure or de facto government or Governmental Authority, in each case other than to the extent solely as a result of the gross negligence or willful misconduct of Issuing Lender or such L/C Lender (as finally determined by a court of competent jurisdiction).

3.7 Letter of Credit Payments. If any draft shall be presented for payment under any Letter of Credit, the Issuing Lender shall promptly notify the Borrower and the Administrative Agent of the date and amount thereof. The responsibility of the Issuing Lender to the Borrower in connection with any draft presented for payment under any Letter of Credit shall, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including

each draft) delivered under such Letter of Credit in connection with such presentment are substantially in conformity with such Letter of Credit.

3.8 Applications. To the extent that any provision of any Application related to any Letter of Credit is inconsistent with the provisions of this Section 3, the provisions of this Section 3 shall apply.

3.9 Interim Interest. If the Issuing Lender shall make any L/C Disbursement in respect of a Letter of Credit, then, unless either the Borrower shall have reimbursed such L/C Disbursement in full within the time period specified in Section 3.5(a) or the L/C Lenders shall have reimbursed such L/C Disbursement in full on such date as provided in Section 3.5(b), in each case the unpaid amount thereof shall bear interest for the account of the Issuing Lender, for each day from and including the date of such L/C Disbursement to but excluding the date of payment by the Borrower, at the rate per annum that would apply to such amount if such amount were a Loan that is an ABR Loan; provided that the provisions of Section 2.15(c) shall be applicable to any such amounts not paid when due.

3.10 Cash Collateral.

(a) Certain Credit Support Events. Upon the request of the Administrative Agent or the Issuing Lender (i) if the Issuing Lender has honored any full or partial drawing request under any Letter of Credit and such drawing has resulted in an L/C Advance by the L/C Lenders that is not reimbursed by the Borrower or converted into a Loan pursuant to Section 3.5(b), or (ii) if, as of the Letter of Credit Maturity Date, any L/C Exposure for any reason remains outstanding, the Borrower shall, in each case, immediately Cash Collateralize the then effective L/C Exposure in an amount equal to 105% of such L/C Exposure.

At any time that there shall exist a Defaulting Lender, within one (1) Business Day following the request of the Administrative Agent or the Issuing Lender (with a copy to the Administrative Agent), the Borrower shall deliver to the Administrative Agent Cash Collateral in an amount sufficient to cover 105% of the Fronting Exposure relating to the Letters of Credit (after giving effect to Section 2.24(a)(iv) and any Cash Collateral provided by such Defaulting Lender).

(b) Grant of Security Interest. All Cash Collateral (other than credit support not constituting funds subject to deposit) shall be maintained in blocked, non-interest bearing deposit accounts with the Administrative Agent. The Borrower, and to the extent provided by any Lender or Defaulting Lender, such Lender or Defaulting Lender, hereby grants to (and subjects to the control of) the Administrative Agent, for the benefit of the Administrative Agent, the Issuing Lender and the L/C Lenders, and agrees to maintain, a first priority security interest and Lien in all such Cash Collateral and in all proceeds thereof, as security for the Obligations to which such Cash Collateral may be applied pursuant to Section 3.10(c). If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent or any Issuing Lender as herein provided, or that the total amount of such Cash Collateral is less than 105% of the L/C Exposure, Fronting Exposure and other Obligations secured thereby, the Borrower or the relevant Lender or Defaulting Lender, as applicable, will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by such Defaulting Lender).

(c) Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under any of this Section 3.10, Section 2.24 or otherwise in respect of Letters of Credit shall be held and applied to the satisfaction of the specific L/C Exposure, obligations

to fund participations therein (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(d) Termination of Requirement. Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure in respect of Letters of Credit or other Obligations shall no longer be required to be held as Cash Collateral pursuant to this Section 3.10 following (i) the elimination of the applicable Fronting Exposure and other Obligations giving rise thereto (including by the termination of the Defaulting Lender status of the applicable Lender), or (ii) a determination by the Administrative Agent and the Issuing Lender that there exists excess Cash Collateral; provided, however, (A) that Cash Collateral furnished by or on behalf of a Loan Party shall not be released during the continuance of an Event of Default, and (B) that, subject to Section 2.24, the Person providing such Cash Collateral and the Issuing Lender may agree that such Cash Collateral shall not be released but instead shall be held to support future anticipated Fronting Exposure or other obligations, and provided further, that to the extent that such Cash Collateral was provided by the Borrower or any other Loan Party, such Cash Collateral shall remain subject to any security interest and Lien granted pursuant to the Loan Documents.

3.11 Additional Issuing Lenders. The Borrower may, at any time and from time to time with the consent of the Administrative Agent (which consent shall not be unreasonably withheld or delayed) and such Lender, designate one or more additional Lenders to act as an issuing bank under the terms of this Agreement. Any Lender designated as an issuing bank pursuant to this paragraph shall be deemed to be an “Issuing Lender” (in addition to being a Lender) in respect of Letters of Credit issued or to be issued by such Lender, and, with respect to such Letters of Credit.

3.12 Resignation of the Issuing Lender. The Issuing Lender may resign at any time by giving at least 30 days’ prior written notice to the Administrative Agent, the Lenders and the Borrower. Subject to the next succeeding paragraph, upon the acceptance of any appointment as the Issuing Lender hereunder by a Lender that shall agree to serve as successor Issuing Lender, such successor shall succeed to and become vested with all the interests, rights and obligations of the retiring Issuing Lender and the retiring Issuing Lender shall be discharged from its obligations to issue additional Letters of Credit hereunder without affecting its rights and obligations with respect to Letters of Credit previously issued by it. At the time such resignation shall become effective, the Borrower shall pay all accrued and unpaid fees pursuant to Section 3.3. The acceptance of any appointment as the Issuing Lender hereunder by a successor Lender shall be evidenced by an agreement entered into by such successor, in a form satisfactory to the Borrower and the Administrative Agent, and, from and after the effective date of such agreement, (i) such successor Lender shall have all the rights and obligations of the previous Issuing Lender under this Agreement and the other Loan Documents (other than with respect to the rights of the retiring Issuing Lender with respect to Letters of Credit issued by such retiring Issuing Lender) and (ii) references herein and in the other Loan Documents to the term “Issuing Lender” shall be deemed to refer to such successor or to any previous Issuing Lender, or to such successor and all previous Issuing Lenders, as the context shall require. After the resignation of the Issuing Lender hereunder, the retiring Issuing Lender shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Lender under this Agreement and the other Loan Documents with respect to Letters of Credit issued by it prior to such resignation, but shall not be required to issue additional Letters of Credit or to extend, renew or increase any existing Letter of Credit.

3.13 Applicability of UCP and ISP. Unless otherwise expressly agreed by the Issuing Lender and the Borrower, when a Letter of Credit is issued and subject to applicable laws, the Letters of Credit shall be governed by and subject to (a) with respect to standby Letters of Credit, the rules of the ISP, and (b) with respect to commercial Letters of Credit, the rules of the Uniform Customs and Practice

for Documentary Credits, as published in its most recent version by the International Chamber of Commerce on the date any commercial Letter of Credit is issued.

SECTION 4
REPRESENTATIONS AND WARRANTIES

To induce the Administrative Agent and the Lenders to enter into this Agreement and to make the Loans and issue the Letters of Credit, Holdings and Borrower hereby represent and warrant to the Administrative Agent and each Lender, as to themselves and each of their respective Subsidiaries, that:

4.1 Financial Condition.

(a) The internally prepared pro forma income statement of Holdings and its Subsidiaries as of September 30, 2017 has been prepared giving effect to the consummation of the combination of the GENBAND and Sonus businesses and presents fairly in all material respects on a pro forma basis the combined revenues, expenses and net earnings of Holdings and its consolidated Subsidiaries as of September 30, 2017 and for the trailing 9-month period then ended, assuming that such business combination had actually occurred on January 1, 2017.

(b) The audited consolidated balance sheet of the Borrower and its Subsidiaries as of December 31, 2016, and the related consolidated statements of income and of cash flows for the fiscal year ended on such date, present fairly in all material respects the consolidated financial condition of the Borrower and its Subsidiaries as at such date, and the consolidated results of its operations and its consolidated cash flows for the fiscal year then ended. The audited consolidated balance sheet of GENBAND Holdings Company and its Subsidiaries as of December 31, 2016, and the related consolidated statements of income and of cash flows for the fiscal year ended on such date, present fairly in all material respects the consolidated financial condition of GENBAND Holdings Company and its Subsidiaries as at such date, and the consolidated results of its operations and its consolidated cash flows for the fiscal year then ended. The unaudited consolidated balance sheet of the Borrower and its Subsidiaries as at September 30, 2017, and the related unaudited consolidated statements of income and cash flows for the nine-month period ended on such date, present fairly in all material respects the consolidated financial condition of the Borrower and its Subsidiaries as at such date, and the consolidated results of its operations and its consolidated cash flows for the nine-month period then ended (subject to normal year-end audit adjustments). The unaudited consolidated balance sheet of GENBAND Holdings Company and its Subsidiaries as at September 30, 2017, and the related unaudited consolidated statements of income and cash flows for the nine-month period ended on such date, present fairly in all material respects the consolidated financial condition of the GENBAND Holdings Company and its Subsidiaries as at such date, and the consolidated results of its operations and its consolidated cash flows for the nine-month period then ended (subject to normal year-end audit adjustments). All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved (except as approved by the aforementioned firm of accountants and disclosed therein, and except, in the case of any unaudited financial statements, for the omission of notes or other textual disclosures that may be required by GAAP). No Group Member has, as of the Closing Date, any material Guarantee Obligations, contingent liabilities, or any long-term leases or unusual forward or long-term commitments, including any interest rate or foreign currency swap or exchange transaction or other obligation in respect of derivatives, that are not reflected in the most recent financial statements referred to in this paragraph. During the period from December 31, 2016 to and including the date hereof, there has been no Disposition by any Group Member of any material part of the business or property of the Group Members, taken as a whole.

4.2 No Change. Since December 31, 2016, there has been no development or event that has had or could reasonably be expected to have a Material Adverse Effect.

4.3 Existence; Compliance with Law. Each Group Member (a) other than any Immaterial Subsidiary that is not a Loan Party is duly organized or incorporated, validly existing and in good standing under the laws of the jurisdiction of its organization or incorporation, (b) has the power and authority, and the legal right, to own and operate its property, to lease the property it operates as lessee and to conduct the business in which it is currently engaged, (c) is duly qualified as a foreign corporation or other organization and in good standing under the laws of each jurisdiction where the failure to be so qualified could reasonably be expected to have a Material Adverse Effect and (d) is in material compliance with all Requirements of Law except in such instances in which (i) such Requirement of Law is being contested in good faith by appropriate proceedings diligently conducted and the prosecution of such contest would not reasonably be expected to result in a Material Adverse Effect, or (ii) the failure to comply therewith, either individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect.

4.4 Power, Authorization; Enforceable Obligations. Each Loan Party has the power and authority, and the legal right, to make, deliver and perform the Loan Documents to which it is a party and, in the case of the Borrower, to obtain extensions of credit hereunder. Each Loan Party has taken all necessary organizational or corporate action to authorize the execution, delivery and performance of the Loan Documents to which it is a party and, in the case of the Borrower, to authorize the extensions of credit on the terms and conditions of this Agreement. No Governmental Approval or consent or authorization of, filing with, notice to or other act by or in respect of, any other Person is required in connection with the extensions of credit hereunder or with the execution, delivery, performance, validity or enforceability of this Agreement or any of the Loan Documents, except Governmental Approvals, consents, authorizations, filings and notices that have been obtained or made and are in full force and effect, (ii) the filings referred to in Section 4.19 and any other filings from time to time required under the Guarantee and Collateral Agreement, and (iii) routine Tax filings. Each Loan Document has been duly executed and delivered on behalf of each Loan Party party thereto. This Agreement constitutes, and each other Loan Document upon execution will constitute, a legal, valid and binding obligation of each Loan Party party thereto, enforceable against each such Loan Party in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law).

4.5 No Legal Bar. The execution, delivery and performance of this Agreement and the other Loan Documents, the issuance of Letters of Credit, the borrowings hereunder and the use of the proceeds thereof will not violate any material Requirement of Law (except as set forth on Schedule 4.5), its Operating Documents or any material Contractual Obligation of any Group Member and will not result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any Requirement of Law or any Contractual Obligation (other than the Liens created by the Security Documents). No Group Member has violated any Requirement of Law or violated or failed to comply with any Contractual Obligation or any provision of an Operating Document applicable to Holdings or any of its Subsidiaries that could reasonably be expected to have a Material Adverse Effect. The violations of Requirements of Law referenced on Schedule 4.5 shall not have a material adverse effect on any rights of the Lenders or the Administrative Agent pursuant to the Loan Documents.

4.6 Litigation. (a) No litigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of Holdings and the Borrower, threatened by or against any Group Member or against any of their respective properties or revenues, and (b) to the knowledge of the Group Members, no investigation concerning any Group Member is pending or threatened, in each case

of (a) and (b), (i) with respect to any of the Loan Documents or any of the transactions contemplated hereby or thereby, or (ii) that could reasonably be expected to have a Material Adverse Effect.

4.7 No Default. No Group Member is in default under or with respect to any of its Contractual Obligations in any respect that could reasonably be expected to have a Material Adverse Effect. No Default or Event of Default has occurred and is continuing, nor shall either result from the making of a requested credit extension under this Agreement.

4.8 Ownership of Property; Liens; Investments. Each Group Member has title in fee simple to, or a valid leasehold interest in, all of its real property, and good title to, or a valid leasehold interest in, all of its other property, and none of such property is subject to any Lien except as permitted by Section 7.3. No Loan Party owns any Investment except as permitted by Section 7.8. Section 10 of the Collateral Information Certificate sets forth a complete and accurate list of all real property owned by each Loan Party as of the Closing Date, if any. Section 11 of the Collateral Information Certificate sets forth a complete and accurate list of all leases of real property under which any Loan Party is the lessee as of the Closing Date.

4.9 Intellectual Property. Each Group Member owns, or is licensed to use, to the knowledge of such Group Member, all Intellectual Property necessary for the conduct of its business as currently conducted. Except as listed on Schedule 4.9, no claim has been asserted and is pending by any Person challenging or questioning any Group Member’s use of any Intellectual Property or the validity of any Group Member’s Intellectual Property, nor does Holdings or the Borrower know of any valid basis for any such claim, unless such claim could not reasonably be expected to have a Material Adverse Effect. The use of Intellectual Property by each Group Member, and the conduct of such Group Member’s business, as currently conducted, does not infringe on or otherwise violate the rights of any Person, unless such infringement or violation could not reasonably be expected to have a Material Adverse Effect, and there are no claims pending or, to the knowledge of Holdings and the Borrower, threatened to such effect, unless such claim could not reasonably be expected to have a Material Adverse Effect.

4.10 Taxes. Each Group Member has filed or caused to be filed all income and all other material state and other material tax returns that are required to be filed by it and has paid all material taxes shown to be due and payable by it on said returns or on any assessments made against it or any of its property and all other material taxes, fees or other charges imposed on it or any of its property by any Governmental Authority that are due and payable (other than (a) any taxes, fees or charges the amount or validity of which are currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the relevant Group Member or (b) amounts not to exceed $500,000 at any time); no tax Lien has been filed on any property of a Loan Party that is still in effect (other than Liens permitted by Section 7.3(a)), and, to the knowledge of Holdings and the Borrower, no claim is being asserted by any Governmental Authority, with respect to any such tax, fee or other charge that is not being contested in good faith and by appropriate proceedings.

4.11 Federal Regulations. The Borrower is not engaged and will not engage, principally or as one of its important activities, in the business of “buying’ or “carrying” “margin stock” (within the respective meanings of each of the quoted terms under Regulation U as now and from time to time hereafter in effect) or extending credit for the purpose of purchasing or carrying margin stock. No part of the proceeds of any Loans, and no other extensions of credit hereunder, will be used for buying or carrying any such margin stock or for extending credit to others for the purpose of purchasing or carrying margin stock in violation of Regulations T, U or X of the Board. If any margin stock directly or indirectly constitutes Collateral securing the Obligations, if requested by any Lender or the Administrative Agent, the Borrower will furnish to the Administrative Agent and each Lender a statement

to the foregoing effect in conformity with the requirements of FR Form G-3 or FR Form U-1, as applicable, referred to in Regulation U.

No Loan Party is an “investment company,” or a company “controlled” by an “investment company,” within the meaning of the Investment Company Act of 1940, as amended. Except as set forth on Schedule 4.5, no Loan Party is subject to regulation under any Requirement of Law (other than Regulation X of the Board) that limits its ability to incur Indebtedness or which may otherwise render all or any portion of the Obligations unenforceable.

4.15 Subsidiaries.

SECTION 9
THE ADMINISTRATIVE AGENT

9.1 Appointment and Authority.

(a) Each of the Lenders hereby irrevocably appoints SVB to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto.

(b) The provisions of Section 9 are solely for the benefit of the Administrative Agent, the Lenders, the Issuing Lender, and the Swingline Lender, and neither the Borrower nor any other Loan Party shall have rights as a third party beneficiary of any of such provisions. Notwithstanding any provision to the contrary elsewhere in this Agreement, the Administrative Agent shall not have any duties or obligations, except those expressly set forth herein and in the other Loan Documents, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Administrative Agent. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

(c) The Administrative Agent shall also act as the collateral agent under the Loan Documents, and each of the Lenders (in their respective capacities as a Lender and, as applicable, Qualified Counterparty and provider of Cash Management Services) hereby irrevocably (i) authorizes the Administrative Agent to enter into all other Loan Documents, as applicable, including the Guarantee and Collateral Agreement and any Subordination Agreements, and (ii) appoints and authorizes the Administrative Agent to act as the agent of the Secured Parties for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of the Loan Parties to secure any of the Obligations, together with such powers and discretion as are reasonably incidental thereto. The Administrative Agent, as collateral agent and any co-agents, sub-agents and attorneys-in-fact appointed by the Administrative Agent pursuant to Section 9.2 for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Security Documents, or for exercising any rights and remedies thereunder at the direction of the Administrative Agent), shall be entitled to the benefits of all provisions of this Section 9 and Section 10 (including Section 9.7, as though such co-agents, sub-agents and attorneys-in-fact were the collateral agent under the Loan Documents) as if set forth in full herein with respect thereto. Without limiting the generality of the foregoing, the Administrative Agent is further authorized on behalf of all the Lenders, without the necessity of any notice to or further consent from the Lenders, from time to time to take any action, or permit the any co-agents, sub-agents and attorneys-in-fact appointed by the Administrative Agent to take any action, with respect to any Collateral or the Loan Documents which may be necessary to perfect and maintain perfected the Liens upon any Collateral granted pursuant to any Loan Document.

9.2 Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Section shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the Facilities provided for herein as well as activities as the Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub agents.

9.3 Exculpatory Provisions. The Administrative Agent shall have no duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder and thereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent shall not:

(a) be subject to any fiduciary or other implied duties, regardless of whether any Default or any Event of Default has occurred and is continuing;

(b) have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), as applicable; provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable law, including for the avoidance of doubt any action that may be in violation of the automatic stay under any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law; and

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

The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 8.2 and 10.1), or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment.

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 or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Section 5.1, Section 5.2 or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

9.4 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making

100

of a Loan, or the issuance, extension, renewal or increase of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender unless the Administrative Agent shall have received notice to the contrary from such Lender prior to the making of such Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for any of the Loan Parties), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. The Administrative Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or such other number or percentage of Lenders as shall be provided for herein or in the other Loan Documents) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or such other number or percentage of Lenders as shall be provided for herein or in the other Loan Documents), and such request and any action taken or failure to act pursuant thereto shall be binding upon the Lenders and all future holders of the Loans.

9.5 Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default unless the Administrative Agent has received notice in writing from a Lender, Holdings or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default.” In the event that the Administrative Agent receives such a notice, the Administrative Agent shall give notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents); provided that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action or refrain from taking such action with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders.

9.6 Non-Reliance on Administrative Agent and Other Lenders. Each Lender expressly acknowledges that neither the Administrative Agent nor any of its officers, directors, employees, agents, attorneys in fact or affiliates has made any representations or warranties to it and that no act by the Administrative Agent hereafter taken, including any review of the affairs of a Group Member or any Affiliate of a Group Member, shall be deemed to constitute any representation or warranty by the Administrative Agent to any Lender. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties, and based on such documents and information as it has deemed appropriate, made its own appraisal of, and investigation into, the business, operations, property, financial and other condition and creditworthiness of the Group Members and their affiliates and made its own credit analysis and decision to make its Loans hereunder and enter into this Agreement. Each Lender also agrees that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties, and based on such documents and information as it shall from time to time deem appropriate, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under or based upon this Agreement, the other Loan Documents or any related agreement or any document furnished hereunder or thereunder, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Group Members and their affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative Agent

101

shall have no duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of any Group Member or any Affiliate of a Group Member that may come into the possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys in fact or affiliates.

9.7 Indemnification. Each of the Lenders agrees to indemnify each of the Administrative Agent, the Issuing Lender and the Swingline Lender and each of its Related Parties in its capacity as such (to the extent not reimbursed by Holdings, the Borrower or any other Loan Party and without limiting the obligation of Holdings, the Borrower, or any other Loan Party to do so) according to its Revolving Percentage in effect on the date on which indemnification is sought under this Section 9.7 (or, if indemnification is sought after the date upon which the Commitments shall have terminated and the Loans shall have been paid in full, in accordance with its Revolving Percentage immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (whether before or after the payment of the Loans) be imposed on, incurred by or asserted against the Administrative Agent or such other Person in any way relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Administrative Agent or such other Person under or in connection with any of the foregoing and any other amounts not reimbursed by Holdings, the Borrower or such other Loan Party; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted primarily from the Administrative Agent’s or such other Person’s gross negligence or willful misconduct. The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder.

9.8 Agent in Its Individual Capacity. The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower, Holdings or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

9.9 Successor Administrative Agent.

(a) The Administrative Agent may at any time give notice of its resignation to the Lenders and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right to appoint a successor Administrative Agent with an office in the United States and, so long as no Event of Default has occurred and is continuing, that is reasonably acceptable to the Borrower. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Administrative Agent may (but shall not be obligated to), on behalf of the Lenders, appoint a successor Administrative Agent meeting the qualifications set forth above; provided that in no event shall any such successor Administrative Agent be a Defaulting Lender. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date.

102

(b) If the Person serving as Administrative Agent is a Defaulting Lender pursuant to clause (d) of the definition thereof, the Required Lenders may, to the extent permitted by applicable law, by notice in writing to the Borrower and such Person remove such Person as Administrative Agent and, in consultation with the Borrower, appoint a successor with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days (or such earlier day as shall be agreed by the Required Lenders) (the “Removal Effective Date”), then such removal shall nonetheless become effective in accordance with such notice on the Removal Effective Date.

(c) With effect from the Resignation Effective Date or the Removal Effective Date (as applicable) (i) the retiring or removed Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Secured Parties under any of the Loan Documents, the retiring or removed Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed and such collateral security is assigned to such successor Administrative Agent) and (ii) except for any indemnity payments owed to the retiring or removed Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above in this Section. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring or removed Administrative Agent (other than any rights to indemnity payments owed to the retiring or removed Administrative Agent), and the retiring or removed Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this Section). The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring or removed Administrative Agent’s resignation or removal hereunder and under the other Loan Documents, the provisions of Section 9 and Section 10.5 shall continue in effect for the benefit of such retiring or removed 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 the retiring or removed Administrative Agent was acting as the Administrative Agent.

9.10 Collateral and Guaranty Matters.

(a) The Lenders irrevocably authorize the Administrative Agent, at its option and in its discretion,

(i) to release any Lien on any Collateral or other property granted to or held by the Administrative Agent under any Loan Document (i) upon the Discharge of Obligations (other than contingent indemnification obligations) and the expiration or termination of all Letters of Credit (other than Letters of Credit as to which other arrangements have been made in accordance with this Agreement or otherwise reasonably satisfactory to the Administrative Agent and the applicable Issuing Lender), (ii) that is sold or otherwise disposed of or to be sold or otherwise disposed of as part of or in connection with any sale or other disposition permitted hereunder or under any other Loan Document, or (iii) subject to Section 10.1, if approved, authorized or ratified in writing by the Required Lenders;

(ii) to subordinate any Lien on any Collateral or other property (including, without limitation, to enter into any intercreditor agreement, subordination agreement or similar agreement) granted to or held by the Administrative Agent under any Loan Document to the holder of any Lien on such property that is permitted by Sections 7.3(f), (g), (i), (m), (n) and (t); and

103

(iii) to release any Guarantor from its obligations under the Guarantee and Collateral Agreement if such Person ceases to be a Subsidiary as a result of a transaction permitted under the Loan Documents.

Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any Guarantor from its obligations under the guaranty pursuant to this Section 9.10.

(b) The Administrative Agent shall not be responsible for or have a duty to ascertain or inquire into any representation or warranty regarding the existence, value or collectability of the Collateral, the existence, priority or perfection of the Administrative Agent’s Lien thereon, or any certificate prepared by any Loan Party in connection therewith, nor shall the Administrative Agent be responsible or liable to the Lenders for any failure to monitor or maintain any portion of the Collateral.

(c) Notwithstanding anything contained in any Loan Document, no Secured Party shall have any right individually to realize upon any of the Collateral or to enforce any guaranty of the Obligations (including any such guaranty provided by the Guarantors pursuant to the Guarantee and Collateral Agreement), it being understood and agreed that all powers, rights and remedies under the Loan Documents may be exercised solely by the Administrative Agent on behalf of the Secured Parties in accordance with the terms thereof; provided that, for the avoidance of doubt, in no event shall a Secured Party be restricted hereunder from filing a proof of claim on its own behalf during the pendency of a proceeding relative to any Loan Party under any Debtor Relief Law or any other judicial proceeding. In the event of a foreclosure by the Administrative Agent on any of the Collateral pursuant to a public or private sale or other disposition, the Administrative Agent or any Secured Party may be the purchaser or licensor of any or all of such Collateral at any such sale or other disposition, and the Administrative Agent, as agent for and representative of such Secured Party (but not any Lender or Lenders in its or their respective individual capacities unless the Required Lenders shall otherwise agree in writing) shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Collateral sold at any such public sale, to use and apply any of the Obligations as a credit on account of the purchase price for any Collateral payable by the Administrative Agent on behalf of the Secured Parties at such sale or other disposition. Each Secured Party, whether or not a party hereto, will be deemed, by its acceptance of the benefits of the Collateral and of the guarantees of the Obligations provided by the Loan Parties under the Guarantee and Collateral Agreement, to have agreed to the foregoing provisions. In furtherance of the foregoing, and not in limitation thereof, no Specified Swap Agreement and no Cash Management Agreement, the Obligations under which constitute Obligations, will create (or be deemed to create) in favor of any Secured Party that is a party thereto any rights in connection with the management or release of any Collateral or of the Obligations of any Loan Party under any Loan Document except as expressly provided herein or in the Guarantee and Collateral Agreement. By accepting the benefits of the Collateral and of the guarantees of the Obligations provided by the Loan Parties under the Guarantee and Collateral Agreement, any Secured Party that is a Cash Management Bank or a Qualified Counterparty shall be deemed to have appointed the Administrative Agent to serve as administrative agent and collateral agent under the Loan Documents and to have agreed to be bound by the Loan Documents as a Secured Party thereunder, subject to the limitations set forth in this paragraph.

9.11 Administrative Agent May File Proofs of Claim. In case of the pendency of any proceeding under any Debtor Relief Law or any other judicial proceeding relative to any Loan Party, the Administrative Agent (irrespective of whether the principal of any Loan or Obligation in respect of any Letter of Credit shall then be due and payable as herein expressed or by declaration or otherwise and

104

irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered (but not obligated), by intervention in such proceeding or otherwise:

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, Obligations in respect of any Letter of Credit and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under Sections 2.9 and 10.5) allowed in such judicial proceeding; and

(b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Sections 2.9 and 10.5.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender to authorize the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

9.12 No Other Duties, etc.. Anything herein to the contrary notwithstanding, the “Lead Arranger” listed on the cover page hereof shall not have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent, a Lender, the Issuing Lender or the Swingline Lender hereunder.

9.13 Cash Management Bank and Qualified Counterparty Reports. Each Cash Management Bank and each Qualified Counterparty agrees to furnish to the Administrative Agent, as frequently as the Administrative Agent may reasonably request, with a summary of all Obligations in respect of Cash Management Services and/or Specified Swap Agreements, as applicable, due or to become due to such Cash Management Bank or Qualified Counterparty, as applicable. In connection with any distributions to be made hereunder, the Administrative Agent shall be entitled to assume that no amounts are due to any Cash Management Bank or Qualified Counterparty (in its capacity as a Cash Management Bank or Qualified Counterparty and not in its capacity as a Lender) unless the Administrative Agent has received written notice thereof from such Cash Management Bank or Qualified Counterparty and if such notice is received, the Administrative Agent shall be entitled to assume that the only amounts due to such Cash Management Bank or Qualified Counterparty on account of Cash Management Services or Specified Swap Agreements are set forth in such notice.

9.14 Survival. This Section 9 shall survive the Discharge of Obligations.

105

SECTION 10
MISCELLANEOUS

10.1 Amendments and Waivers.

(a) Neither this Agreement, any other Loan Document (other than any L/C Related Document or any Specified Swap Agreement), nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this Section 10.1. The Required Lenders and each Loan Party party to the relevant Loan Document may, or, with the written consent of the Required Lenders, the Administrative Agent and each Loan Party party to the relevant Loan Document may, from time to time, (i) enter into written amendments, supplements or modifications hereto and to the other Loan Documents for the purpose of adding any provisions to this Agreement or the other Loan Documents or changing in any manner the rights of the Lenders or of the Loan Parties hereunder or thereunder or (ii) waive, on such terms and conditions as the Required Lenders or the Administrative Agent, as the case may be, may specify in such instrument, any of the requirements of this Agreement or the other Loan Documents or any Default or Event of Default and its consequences; provided that no such waiver and no such amendment, supplement or modification shall (A) forgive the principal amount or extend the final scheduled date of maturity of any Loan, reduce the stated rate of any interest or fee payable hereunder (except that any amendment or modification of defined terms used in the financial covenants in this Agreement shall not constitute a reduction in the rate of interest or fees for purposes of this clause (A)) or extend the scheduled date of any payment thereof, or increase the amount or extend the expiration date of any Lender’s Commitment, in each case, without the written consent of each Lender directly affected thereby; (B) eliminate or reduce the voting rights of any Lender under this Section 10.1 without the written consent of such Lender; (C) reduce any percentage specified in the definition of Required Lenders, consent to the assignment or transfer by the Borrower of any of its rights and obligations under this Agreement and the other Loan Documents, release all or substantially all of the Collateral or release all or substantially all of the value of the guarantees (taken as a whole) provided by the Guarantors under the Guarantee and Collateral Agreement, in each case without the written consent of all Lenders; (D) amend, modify or waive the pro rata requirements of Section 2.18 without the written consent of each Lender; (E) amend, modify or waive any provision of Section 9 without the written consent of the Administrative Agent; (F) amend, modify or waive any provision of Section 2.6 or 2.7 without the written consent of the Swingline Lender; (G) amend, modify or waive any provision of Section 3 without the written consent of the Issuing Lender; or (H) (i) amend or modify the application of prepayments set forth in Section 2.12(e) or the application of payments set forth in Section 8.3 without the written consent of each Lender and each L/C Lender, or (iii) amend or modify the application of payments provisions set forth in Section 8.3 in a manner that adversely affects the Issuing Lender, any Cash Management Bank or any Qualified Counterparty, as applicable, without the written consent of the Issuing Lender, such Cash Management Bank or any such Qualified Counterparty, as applicable. Any such waiver and any such amendment, supplement or modification shall apply equally to each of the Lenders and shall be binding upon the Loan Parties, the Lenders, the Administrative Agent, the Issuing Lender, each Cash Management Bank, each Qualified Counterparty, and all future holders of the Loans. In the case of any waiver, the Loan Parties, the Lenders and the Administrative Agent shall be restored to their former position and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured during the period such waiver is effective; but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon.

(b) Notwithstanding anything to the contrary contained in Section 10.1(a) above, in the event that the Borrower requests that this Agreement or any of the other Loan Documents be amended or otherwise modified in a manner which would require the consent of all of the Lenders and such amendment or other modification is agreed to by the Borrower, the Required Lenders and the Administrative Agent, then, with the consent of the Borrower, the Administrative Agent and the Required Lenders, this Agreement or such other Loan Document may be amended without the consent of the Lender or Lenders who are unwilling to agree to such amendment or other modification (each, a “Minority Lender”), to provide for:

106

(i) the termination of the Commitment of each such Minority Lender;

(ii) the assumption of the Loans and Commitment of each such Minority Lender by one or more Replacement Lenders pursuant to the provisions of Section 2.23; and

(iii) the payment of all interest, fees and other obligations payable or accrued in favor of each Minority Lender and such other modifications to this Agreement or to such Loan Documents as the Borrower, the Administrative Agent and the Required Lenders may determine to be appropriate in connection therewith.

(c) Notwithstanding any provision herein or in any Loan Document to the contrary, no amendment, supplement, modification, consent or waiver of this Agreement or any Loan Document altering the treatment of Obligations arising under Specified Swap Agreements or Cash Management Agreements resulting in such Obligations being subordinated to the other Obligations (other than as contemplated by Section 8.3) or resulting in the Obligations owing to any Qualified Counterparty or Cash Management Bank becoming unsecured (other than releases of Liens permitted in accordance with Section 10.16), shall be effective without the written consent of such Qualified Counterparty or Cash Management Bank, as applicable.

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

10.4 Survival of Representations and Warranties.

(a) Costs and Expenses. The Borrower shall pay (i) all reasonable and documented out-of-pocket expenses incurred by the Administrative Agent and its Affiliates (including the reasonable and documented fees, charges and disbursements of outside counsel for the Administrative Agent), in connection with the syndication of the Facilities, the preparation, negotiation, execution, delivery and administration of this Agreement and the other Loan Documents, or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable and documented out-of-pocket expenses incurred by the Issuing Lender in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder, and (iii) all reasonable and documented out-of-pocket expenses incurred by the Administrative Agent or any Lender (including all reasonable and documented fees, charges and disbursements of any outside counsel for the Administrative Agent or any Lender), in connection with the enforcement or protection of its rights (A) in connection with this Agreement and the other Loan Documents, including its rights under this Section, or (B) in connection with the Loans made

109

or Letters of Credit issued or participated in hereunder, including all such reasonable and documented out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit.

(b) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent (and any sub-agent thereof), each Lender (including the Issuing 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 reasonable and documented fees, charges and disbursements of any outside counsel for any Indemnitee), incurred by any Indemnitee or asserted against any Indemnitee by any Person (including the Borrower or any other Loan Party) other than such Indemnitee and its Related Parties arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby or thereby, (ii) any Loan or Letter of Credit or the use or proposed use of the proceeds therefrom (including any refusal by the Issuing Lender to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Materials of Environmental Concern on or from any property owned or operated by Holdings or any of its Subsidiaries, or any Environmental Liability related in any way to Holdings 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, whether brought by a third party or by the Borrower or any other Loan Party, and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or any Related Party, (y) arise solely from disputes between or among Indemnitees to the extent that any such dispute did not arise due to an act or omission by Holdings or any of its Subsidiaries or (z) result from a claim brought by the Borrower or any other Loan Party against an Indemnitee for breach in bad faith of such Indemnitee’s obligations hereunder or under any other Loan Document, if the Borrower or such Loan Party has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction. This Section 10.5(b) shall not apply with respect to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim.

(c) Reimbursement by Lenders. To the extent that the Borrower for any reason fail indefeasibly to pay any amount required under paragraph (a) or (b) of this Section to be paid by it to the Administrative Agent (or any sub-agent thereof), the Issuing Lender, the Swingline Lender or any Related Party of any of the foregoing, each Lender severally agrees to pay to the Administrative Agent (or any such sub-agent), the Issuing Lender, the Swingline Lender or such Related Party, as the case may be, such Lender’s pro rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought based on each Lender’s share of the Total Credit Exposure at such time) of such unpaid amount (including any such unpaid amount in respect of a claim asserted by such Lender); 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 (or any such sub-agent), the Issuing Lender or the Swingline Lender in its capacity as such, or against any Related Party of any of the foregoing acting for the Administrative Agent (or any such sub-agent), the Issuing Lender or the Swingline Lender in connection with such capacity. The obligations of the Lenders under this paragraph (c) are subject to the provisions of Sections 2.4 and 2.20(e).

(d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable law, the Borrower shall not assert, and the Borrower hereby waives, any claim against any

110

Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or Letter of Credit, or the use of the proceeds thereof. Absent the gross negligence or willful misconduct of an Indemnitee, as determined by a court of competent jurisdiction by a final and non-appealable judgment, no Indemnitee referred to in paragraph (b) above shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby.

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

(f) Survival. Each party’s obligations under this Section shall survive the Discharge of Obligations.

10.6 Successors and Assigns; Participations and Assignments.

(a) Successors and Assigns Generally. 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 (which, for purposes of this Section 10.6, shall include any Cash Management Bank and any Qualified Counterparty, except that neither the Borrower nor any other Loan Party may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender, and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of Section 10.6(d), or (iii) by way of pledge or assignment of a security interest subject to the restrictions of Section 10.6(e). 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 (d) 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) Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and/or the Loans at the time owing to it or contemporaneous assignments to related Approved Funds (determined after giving effect to such assignments) that equal at least the amount specified in paragraph (b)(i)(B) of this Section in the aggregate or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B) in any case not described in paragraph (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans

111

outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the 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 or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000, unless each of the Administrative Agent and, so long as no Default or Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed).

(ii) Proportionate Amounts. 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 with respect to the Loan or the Commitment assigned.

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by paragraph (b)(i)(B) of this Section and, in addition:

(A) the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) a Default or an Event of Default has occurred and is continuing at the time of such assignment, or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five Business Days after having received notice thereof;

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required if such assignment is to a Person that is not a Lender, an Affiliate of such Lender or an Approved Fund with respect to such Lender;

(iv) Assignment and Assumption. 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; provided that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment. The assignee, if it is not a Lender, shall deliver to the Administrative Agent any such administrative questionnaire as the Administrative Agent may request.

(v) No Assignment to Certain Persons. No such assignment shall be made to (A) the Borrower or any of the Borrower’s Affiliates or Subsidiaries, (B) to any Defaulting Lender or any of its Affiliates, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B), or (C) so long as no Event of Default has occurred and is continuing, an Excluded Lender.

(vi) No Assignment to Natural Persons. No such assignment shall be made to a natural Person (or a holding company, investment vehicle or trust established for, or owned and operated for the primary benefit of, a natural Person).

(vii) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless

112

and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, the Issuing Lender, the Swingline Lender and each other Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Letters of Credit and Swingline Loans in accordance with its Revolving Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.19, 2.20, 2.21 and 10.5 with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph 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 (d) of this Section.

(c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in the United States a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and stated interest) of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural Person, the Borrower or any of the Borrower’s Affiliates or Subsidiaries, or, so long as no Event of Default has occurred and is continuing, an Excluded Lender) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and (iii) the Borrower, the Administrative Agent, the Issuing Lender and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be

113

responsible for the indemnities under Sections 2.20(e) and 9.7 with respect to any payments made by such Lender to its Participant(s).

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 which affects such Participant and for which the consent of such Lender is required (as described in Section 10.1). The Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.19 (other than Section 2.19(a)), 2.20 and 2.21 (subject to the requirements and limitations therein, including the requirements under Section 2.20(f) (it being understood that the documentation required under Section 2.20(f) shall be delivered by such Participant to the Lender granting such participation)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 10.6(b); provided that such Participant (A) agrees to be subject to the provisions of Sections 2.22 and 2.23 as if it were an assignee under Section 10.6(b); and (B) shall not be entitled to receive any greater payment under Sections 2.19 or 2.20, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a change in any Requirement of Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower’s request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 2.23 with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.7 as though it were a Lender; provided that such Participant agrees to be subject to Section 2.18(k) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(e) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(f) Notes. The Borrower, upon receipt by the Borrower of written notice from the relevant Lender, agrees to issue Notes to any Lender requiring Notes to facilitate transactions of the type described in Section 10.6.

(g) Representations and Warranties of Lenders. Each Lender, upon execution and delivery hereof or upon succeeding to an interest in the Commitments or Loans, as the case may be, represents and warrants as of the Closing Date or as of the effective date of the applicable Assignment and Assumption that (i) it is an Eligible Assignee; (ii) it has experience and expertise in the making of or

114

investing in commitments, loans or investments such as the Commitments and Loans; and (iii) it will make or invest in its Commitments and Loans for its own account in the ordinary course of its business and without a view to distribution of such Commitments and Loans within the meaning of the Securities Act or the Exchange Act, or other federal securities laws (it being understood that, subject to the provisions of this Section 10.6, the disposition of such Commitments and Loans or any interests therein shall at all times remain within its exclusive control).

10.7 Adjustments; Set-off.

(a) Except to the extent that this Agreement expressly provides for payments to be allocated to a particular Lender or to the Lenders, if any Lender (a “Benefitted Lender”) shall, at any time after the Loans and other amounts payable hereunder shall immediately become due and payable pursuant to Section 8.2, receive any payment of all or part of the Obligations owing to it, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 8.1(f), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of the Obligations owing to such other Lender, such Benefitted Lender shall purchase for cash from the other Lenders a participating interest in such portion of the Obligations owing to each such other Lender, or shall provide such other Lenders with the benefits of any such collateral, as shall be necessary to cause such Benefitted Lender to share the excess payment or benefits of such collateral ratably with each of the Lenders; provided that if all or any portion of such excess payment or benefits is thereafter recovered from such Benefitted Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest.

(b) Upon (i) the occurrence and during the continuance of any Event of Default and (ii) obtaining the prior written consent of the Administrative Agent, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, without prior notice to the Borrower or any other Loan Party, any such notice being expressly waived by the Borrower and each Loan Party, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final), in any currency, at any time held or owing, and any other credits, indebtedness, claims or obligations, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender, its Affiliates or any branch or agency thereof to or for the credit or the account of the Borrower or any other Loan Party, as the case may be, against any and all of the obligations of the Borrower or such other Loan Party now or hereafter existing under this Agreement or any other Loan Document to such Lender or its Affiliates, irrespective of whether or not such Lender or Affiliate shall have made any demand under this Agreement or any other Loan Document and although such obligations of the Borrower or such other Loan Party may be contingent or unmatured or are owed to a branch, office or Affiliate of such Lender different from the branch, office or Affiliate holding such deposit or obligated on such indebtedness; provided, that in the event that any Defaulting Lender or any of its Affiliates shall exercise any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.23 and, pending such payment, shall be segregated by such Defaulting Lender or Affiliate thereof from its other funds and deemed held in trust for the benefit of the Administrative Agent and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender or Affiliate thereof as to which it exercised such right of setoff. Each Lender agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application made by such Lender or any of its Affiliates; provided that the failure to give such notice shall not affect the validity of such setoff and application. The rights of each Lender and its Affiliates under this Section 10.7 are in addition to other rights and remedies (including other rights of set-off) which such Lender or its Affiliates may have.

115

10.8 Payments Set Aside. To the extent that any payment by or on behalf of the Borrower is made to the Administrative Agent or any Lender, or the Administrative Agent or any Lender exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Administrative Agent or such Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any Insolvency Proceeding or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred, and (b) each Lender severally agrees to pay to the Administrative Agent upon demand its applicable share (without duplication) of any amount so recovered from or repaid by the Administrative Agent, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the Federal Funds Effective Rate from time to time in effect. The obligations of the Lenders under clause (b) of the preceding sentence shall survive the Discharge of Obligations.

10.9 Interest Rate Limitation. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable law (the “Maximum Rate”). If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the Borrower. In determining whether the interest contracted for, charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

10.10 Counterparts; Electronic Execution of Assignments.

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

(b) The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

10.11 Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. Without limiting the foregoing provisions of this Section 10.11, if and to the extent that the enforceability of any provisions in this Agreement relating to Defaulting Lenders shall be limited under or in connection with any Insolvency Proceeding, as determined in good faith by the Administrative

116

Agent or the Issuing Lender, as applicable, then such provisions shall be deemed to be in effect only to the extent not so limited.

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

Each of Holdings and the Borrower expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and each of Holdings and the Borrower hereby waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate by such court. Each of Holdings and the Borrower hereby waives personal service of the summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to the Borrower or Holdings at the addresses set forth in Section 10.2 of this Agreement and that service so made shall be deemed completed upon the earlier to occur of the Borrower’s or Holdings’, as applicable, actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage prepaid;

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

117

(b) none of the Administrative Agent nor any Lender has any fiduciary relationship with or duty to Holdings or the Borrower arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between the Administrative Agent and Lenders, on one hand, and Holdings and the Borrower, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

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

10.17 Treatment of Certain Information; Confidentiality. Each of the Administrative Agent and each Lender agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its Related Parties (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential); (b) to the extent required or requested by any regulatory authority purporting to have jurisdiction over such Person or its Related Parties (including any self-regulatory authority, such as the National Association of Insurance Commissioners); (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process; (d) to any other party hereto; (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder; (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights and obligations under this Agreement (other than, so long as no Event of Default has occurred and is continuing, to an Excluded Lender), or (ii) any actual or prospective party (or its Related Parties) to any swap, derivative or other transaction under which payments are to be made by reference to the Borrower and its obligations, this Agreement or payments hereunder; (g) on a confidential basis to (i) any rating agency in connection with rating Holdings or its Subsidiaries or the Facilities or (ii) the CUSIP Service Bureau or any similar agency in connection with the issuance and monitoring of CUSIP numbers with respect to the Facilities; (h) with the consent of the Borrower; or (i) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section, or (y) becomes available to the Administrative Agent, any Lender or any of their

118

respective Affiliates on a non-confidential basis from a source other than the Borrower. In addition, the Administrative Agent, the Lenders, and any of their respective Related Parties, may (A) disclose the existence of this Agreement and information about this Agreement to market data collectors, similar service providers to the lending industry and service providers to the Administrative Agent or the Lenders in connection with the administration of this Agreement, the other Loan Documents, and the Commitments; and (B) use any information (not constituting Information subject to the foregoing confidentiality restrictions) related to the syndication and arrangement of the credit facilities contemplated by this Agreement in connection with marketing, press releases, or other transactional announcements or updates provided to investor or trade publications, including the placement of “tombstone” advertisements in publications of its choice at its own expense.

Notwithstanding anything herein to the contrary, any party to this Agreement (and any employee, representative, or other agent of any party to this Agreement) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the transactions contemplated by this Agreement 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, any such information relating to the tax treatment or tax structure is required to be kept confidential to the extent necessary to comply with any applicable federal or state securities laws, rules, and regulations.

For purposes of this Section, “Information” means all information received from Holdings or any of its Subsidiaries relating to Holdings or any of its Subsidiaries or any of their respective businesses, other than any such information that is available to the Administrative Agent or any Lender on a non-confidential basis prior to disclosure by Holdings or any of its Subsidiaries; provided that, in the case of information received from Holdings or any of its Subsidiaries after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

Without limiting the foregoing, the list of Excluded Lenders may be made available to prospective Lenders and participants on a confidential basis in connection with any bona fide assignment or participation of the Obligations or any portion thereof.

10.18 Automatic Debits. With respect to any principal, interest, fee, or any other cost or expense (including attorney costs of the Administrative Agent or any Lender payable by the Borrower hereunder) due and payable to the Administrative Agent or any Lender under the Loan Documents by the Borrower, the Borrower hereby irrevocably authorizes the Administrative Agent to debit any deposit account of the Borrower maintained with the Administrative Agent in an amount such that the aggregate amount debited from all such deposit accounts does not exceed such principal, interest, fee or other cost or expense. If there are insufficient funds in such deposit accounts to cover the amount then due, such debits will be reversed (in whole or in part, in the Administrative Agent’s sole discretion) and such amount not debited shall be deemed to be unpaid. No such debit under this Section 10.18 shall be deemed a set-off.

119

10.19 Judgment Currency; Exchange Rates.

(a) Judgment Currency. If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder or any other Loan Document in one currency into another currency, the rate of exchange used shall be that at which in accordance with normal banking procedures the Administrative Agent could purchase the first currency with such other currency on the Business Day preceding that on which final judgment is given. The obligation of the Borrower and each other Loan Party in respect of any such sum due from it to the Administrative Agent or any Lender hereunder or under any other Loan Document shall, notwithstanding any judgment in a currency (the “Judgment Currency”) other than that in which such sum is denominated in accordance with the applicable provisions of this Agreement (the “Agreement Currency”), be discharged only to the extent that on the Business Day following receipt by the Administrative Agent or such Lender, as the case may be, of any sum adjudged to be so due in the Judgment Currency, the Administrative Agent or such Lender, as the case may be, may in accordance with normal banking procedures purchase the Agreement Currency with the Judgment Currency. If the amount of the Agreement Currency so purchased is less than the sum originally due to the Administrative Agent or any Lender from the Borrower or any other Loan Party in the Agreement Currency, the Borrower and each other such Loan Party agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Administrative Agent or such Lender, as the case may be, against such loss. If the amount of the Agreement Currency so purchased is greater than the sum originally due to the Administrative Agent or any Lender in such currency, the Administrative Agent or such Lender, as the case may be, agrees to return the amount of any excess to the Borrower or other Loan Party, as applicable (or to any other Person who may be entitled thereto under applicable law).

(b) Currency Conversion. All payments under this Agreement or any other Loan Document shall be made in Dollars. If any payment by the Borrower or the proceeds of any Collateral shall be made in a currency other than the currency required hereunder, such amount shall be converted into the currency required hereunder at the rate reasonably determined by the Administrative Agent or the Issuing Lender, as applicable, as the rate quoted by it in accordance with methods customarily used by such Person for such or similar purposes as the spot rate for the purchase by such Person of the required currency with the currency of actual payment through its principal foreign exchange trading office (including, in the case of the Administrative Agent, any Affiliate) at approximately 11:00 A.M. (local time at such office) two Business Days prior to the effective date of such conversion, provided that the Administrative Agent or the Issuing Lender, as applicable, may obtain such spot rate from another financial institution actively engaged in foreign currency exchange if the Administrative Agent or the Issuing Lender, as applicable, does not then have a spot rate for the required currency.

10.20 Patriot Act. Each Lender and the Administrative Agent (for itself and not on behalf of any other party) hereby notifies Holdings and the Borrower and each other Loan Party that, pursuant to the requirements of “know your customer” and anti-money-laundering rules and regulations, including the Patriot Act, it is required to obtain, verify and record information that identifies Holdings and the Borrower and each other Loan Party, which information includes the names and addresses and other information that will allow such Lender or the Administrative Agent, as applicable, to identify Holdings and the Borrower and each other Loan Party in accordance with such rules and regulations. Each of Holdings and the Borrower and each other Loan Party will, and will cause each of its respective Subsidiaries to, provide, to the extent commercially reasonable or required by any Requirement of Law, such information and take such actions as are reasonably requested by the Administrative Agent or any Lender to assist the Administrative Agent or any such Lender in maintaining compliance with such applicable rules and regulations.

10.21 Acknowledgement and Consent to Bail-In of EEA Financial Institutions. Notwithstanding anything to the contrary in this Agreement or in any other Loan Document, each party hereto acknowledges that any liability of any Lender that is an EEA Financial Institution arising under any Loan Document, to the extent such liability is unsecured, may be subject to the write-down and

120

“Excluded Assets”: collectively,

(a) Equipment owned by any Grantor on the date hereof or hereafter acquired that is subject to a Lien securing a purchase money obligation or Capital Lease Obligation not prohibited by the terms of the Credit Agreement if the contract or other agreement pursuant to which such Lien is granted (or the documentation providing for such purchase money obligation or Capital Lease Obligation) validly prohibits the creation of any other Lien on such Equipment and proceeds of such Equipment;

(b) any Collateral with respect to which the Administrative Agent has determined, in consultation with the Borrower, that is specified in writing that the costs of obtaining a security interest in such Collateral are excessive in relation to the benefits provided to the Secured Parties by such security interest;

(d) margin stock (within the meaning of Regulation U issued by the Board) to the extent the creation of a security interest therein in favor of the Administrative Agent (for the benefit of the Secured Parties) will result in a violation of Regulation U issued by the Board;

(e) motor vehicles and other equipment covered by certificates of title;

(f) Excluded Stock;

(g) Excluded Accounts;

(h) any property to the extent that such grant of a security interest is prohibited by any Requirement of Law of a Governmental Authority or constitutes a breach or default under or results in the termination of or requires any consent not obtained under, any contract, license, agreement, instrument or other document evidencing or giving rise to such property, except to the extent that such Requirement of Law or the term in such contract, license, agreement, instrument or other document providing for such prohibition, breach, default or termination or requiring such consent is ineffective under Section 9-406, 9-407, 9-408 or 9-409 of the UCC (or any successor provision or provisions) of any relevant jurisdiction or any other applicable law (including the Bankruptcy Code) or principles of equity; provided, however, that at such time if any as such Requirement of Law is not effective or applicable, or such prohibition, breach, default or termination is no longer applicable or is waived, and to the extent severable, such property shall not longer constitute Excluded Assets under this clause (h) and any

1.2 Other Definitional Provisions. The rules of interpretation set forth in Section 1.2 of the Credit Agreement are by this reference incorporated herein, mutatis mutandis, as if set forth herein in full.

SECTION 2. GUARANTEE.

2.1 Guarantee.

(a) Each Grantor, including Holdings and the Borrower, who has executed this Agreement as of the date hereof, together with each Loan Party who accedes to this Agreement as a Grantor after the date hereof pursuant to Section 6.12 of the Credit Agreement (each a “Guarantor” and, collectively, the “Guarantors”), hereby, jointly and severally, unconditionally and irrevocably, guarantees to the Administrative Agent, for the benefit of the Secured Parties and their respective successors, indorsees, transferees and assigns, the prompt and complete payment and performance by the Borrower and the other Loan Parties when due (whether at the stated maturity, by acceleration or otherwise) of the Secured Obligations. In furtherance of the foregoing, and without limiting the generality thereof, each Guarantor agrees as follows:

(i) each Guarantor’s liability hereunder shall be the immediate, direct, and primary obligation of such Guarantor and shall not be contingent upon the Administrative Agent’s or any Secured Party’s exercise or enforcement of any remedy it or they may have against the Borrower, any other Guarantor, or any other Person, or all or any portion of the Collateral; and

(ii) the Administrative Agent may enforce this guaranty notwithstanding the existence of any dispute between any of the Secured Parties and the Borrower or any other Guarantor, with respect to the existence of any Event of Default.

(b) Anything herein or in any other Loan Document to the contrary notwithstanding, the maximum liability of each Guarantor hereunder and under the other Loan Documents shall in no event exceed the amount which can be guaranteed by such Guarantor under applicable federal and state laws relating to the insolvency of debtors (after giving effect to the right of contribution established in Section 2.3).

(c) Each Guarantor agrees that the Secured Obligations may at any time and from time to time exceed the amount of the liability of such Guarantor hereunder without impairing the guarantee contained in this Section 2 or affecting the rights and remedies of the Administrative Agent or any other Secured Party hereunder.

(d) The guarantee contained in this Section 2 shall remain in full force and effect until the Discharge of Obligations, notwithstanding that from time to time during the term of the Credit Agreement the outstanding amount of the Secured Obligations may be zero.

(e) No payment made by the Borrower, any Guarantor, or any other Person or received or collected by the Administrative Agent or any other Secured Party from the Borrower, any Guarantor, or any other Person by virtue of any action or proceeding or any setoff or appropriation or application at any time or from time to time in reduction of or in payment of the Secured Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of any Guarantor hereunder which shall, notwithstanding any such payment (other than any payment made by such Guarantor in respect of the Secured Obligations or any payment received or collected from such Guarantor in respect of the Secured Obligations), remain liable for the Secured Obligations up to the maximum liability of such Guarantor hereunder until the Discharge of Obligations.

2.2 [Reserved].

2.3 Right of Contribution. If in connection with any payment made by any Guarantor hereunder any rights of contribution arise in favor of such Guarantor against one or more other Guarantors, such rights of contribution shall be subject to the terms and conditions of Section 2.4. The provisions of this Section 2.3 shall in no respect limit the obligations and liabilities of any Guarantor to the Administrative Agent and the other Secured Parties, and each Guarantor shall remain liable to the Administrative Agent and the other Secured Parties for the full amount guaranteed by such Guarantor hereunder.

2.4 No Subrogation. Notwithstanding any payment made by any Guarantor hereunder or any setoff or application of funds of any Guarantor by the Administrative Agent or any other Secured Party, no Guarantor shall be entitled to be subrogated to any of the rights of the Administrative Agent or any other Secured Party against the Borrower or any other Guarantor or any Collateral or guarantee or right of offset held by the Administrative Agent or any other Secured Party for the payment of the Secured Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Borrower or any other Guarantor in respect of payments made by such Guarantor hereunder, in each case, until the Discharge of Obligations. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time prior to the Discharge of Obligations, such amount shall be held by such Guarantor in trust for the Administrative Agent and the other

Secured Parties, shall be segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Administrative Agent in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Administrative Agent, if required), to be applied in such order as set forth in Section 6.5 hereof irrespective of the occurrence or the continuance of any Event of Default.

2.5 Amendments, etc. with respect to the Secured Obligations. Each Guarantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, any demand for payment of any of the Secured Obligations made by the Administrative Agent or any other Secured Party may be rescinded by the Administrative Agent or such Secured Party and any of the Secured Obligations continued, and the Secured Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, increased, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Administrative Agent or any other Secured Party, and the Credit Agreement, the other Loan Documents, the Specified Swap Agreements, the Cash Management Agreements and any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders or all of the Lenders, as the case may be) and the other parties to such documents that are required in connection therewith may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by the Administrative Agent or any other Secured Party for the payment of the Secured Obligations may be sold, exchanged, waived, surrendered or released in accordance with the Loan Documents and any other documents executed in connection therewith. Neither the Administrative Agent nor any other Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Secured Obligations or for the guarantee contained in this Section 2 or any property subject thereto.

2.6 Guarantee Absolute and Unconditional; Guarantor Waivers; Guarantor Consents. Each Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Secured Obligations and notice of or proof of reliance by the Administrative Agent or any other Secured Party upon the guarantee contained in this Section 2 or acceptance of the guarantee contained in this Section 2; the Secured Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon the guarantee contained in this Section 2; and all dealings between the Borrower and any of the Guarantors on the one hand, and the Administrative Agent and the other Secured Parties, on the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance upon the guarantee contained in this Section 2. Each Guarantor further waives:

(a) diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon the Borrower or any of the other Guarantors with respect to the Secured Obligations;

(b) any right to require any Secured Party to marshal assets in favor of the Borrower, such Guarantor, any other Guarantor or any other Person, to proceed against the Borrower, any other Guarantor or any other Person, to proceed against or exhaust any of the Collateral, to give notice of the terms, time and place of any public or private sale of personal property security constituting the Collateral or other collateral for the Secured Obligations or to comply with any other provisions of Section 9-611 of the UCC (or any equivalent provision of any other applicable law) or to pursue any other right, remedy, power or privilege of any Secured Party whatsoever;

(c) the defense of the statute of limitations in any action hereunder or for the collection or performance of the Secured Obligations;

(d) any defense arising by reason of any lack of corporate or other authority or any other defense of the Borrower, such Guarantor or any other Person;

(e) any defense based upon the Administrative Agent’s or any Secured Party’s errors or omissions in the administration of the Secured Obligations;

(f) any rights to set-offs and counterclaims;

(g) any defense based upon an election of remedies (including, if available, an election to proceed by nonjudicial foreclosure) which destroys or impairs the subrogation rights of such Guarantor or the right of such Guarantor to proceed against the Borrower or any other obligor of the Secured Obligations for reimbursement; and

(h) without limiting the generality of the foregoing, to the fullest extent permitted by law, any defenses or benefits (other than defense of payment or performance) that may be derived from or afforded by applicable law that limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms of this Agreement.

Each Guarantor understands and agrees that the guarantee contained in this Section 2 shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (i) the validity or enforceability of the Credit Agreement, any other Loan Document, any Cash Management Agreement or any Specified Swap Agreement, any of the Secured Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by the Administrative Agent or any other Secured Party, (ii) any defense, setoff or counterclaim (other than a defense of payment or performance) which may at any time be available to or be asserted by the Borrower or any other Person against the Administrative Agent or any other Secured Party, (iii) any other circumstance whatsoever (with or without notice to or knowledge of the Borrower or such Guarantor) which constitutes, or might be construed to constitute, an equitable or legal discharge of the Borrower and the Guarantors for the Secured Obligations, or of such Guarantor under the guarantee contained in this Section 2, in bankruptcy or in any other instance, (iv) any Insolvency Proceeding with respect to the Borrower, any Guarantor or any other Person, (v) any merger, acquisition, consolidation or change in structure of the Borrower, any Guarantor or any other Person, or any sale, lease, transfer or other disposition of any or all of the assets or voting Capital Stock of the Borrower, any Guarantor or any other Person, other than a Disposition of any Guarantor in a transaction permitted under the Credit Agreement, (vi) any assignment or other transfer, in whole or in part, of any Secured Party’s interests in and rights under this Agreement or the other Loan Documents, in each case, in accordance with the terms of the Loan Documents, Cash Management Agreements and Specified Swap Agreements, as applicable, including any Secured Party’s right to receive payment of the Secured Obligations, or any assignment or other transfer, in whole or in part, of any Secured Party’s interests in and to any of the Collateral, (vi) any Secured Party’s vote, claim, distribution, election, acceptance, action or inaction in any Insolvency Proceeding related to any of the Secured Obligations, and (vii) any other guaranty, whether by such Guarantor or any other Person, of all or any part of the Secured Obligations or any other indebtedness, obligations or liabilities of any Guarantor to any Secured Party.

When making any demand hereunder or otherwise pursuing its rights and remedies hereunder against any Guarantor, the Administrative Agent or any other Secured Party may, but shall be

under no obligation to make a similar demand on or otherwise pursue such rights and remedies as it may have against the Borrower, any other Guarantor or any other Person or against any collateral security or guarantee for the Secured Obligations or any right of offset with respect thereto. Any failure by the Administrative Agent or any other Secured Party to make any such demand, to pursue such other rights or remedies or to collect any payments from the Borrower, any other Guarantor or any other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of the Borrower, any other Guarantor or any other Person or any such collateral security, guarantee or right of offset, shall not relieve any Guarantor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Administrative Agent or any other Secured Party against any Guarantor. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings.

Each Guarantor further unconditionally consents and agrees that, in accordance with the Loan Documents and without notice to or further assent from any Guarantor: (a) the principal amount of the Secured Obligations may be increased or decreased and additional indebtedness or obligations of the Borrower or any other Persons under the Loan Documents, Specified Swap Agreements and Cash Management Agreements may be incurred, by one or more amendments, modifications, renewals or extensions of any Loan Document or otherwise; (b) the time, manner, place or terms of any payment under any Loan Document, Specified Swap Agreement and Cash Management Agreement may be extended or changed, including by an increase or decrease in the interest rate on any Secured Obligation or any fee or other amount payable under such Loan Document, Specified Swap Agreement or Cash Management Agreement, as applicable, by an amendment, modification or renewal of any Loan Document, Specified Swap Agreement or Cash Management Agreement or otherwise; (c) the time for the Borrower’s (or any other Loan Party’s) performance of or compliance with any term, covenant or agreement on its part to be performed or observed under any Loan Document, Specified Swap Agreement or Cash Management Agreement may be extended, or such performance or compliance waived, or failure in or departure from such performance or compliance consented to, all in such manner and upon such terms as the Administrative Agent may deem proper; (d) in addition to the Collateral, the Secured Parties may take and hold other security (legal or equitable) of any kind, at any time, as collateral for the Secured Obligations, and may, from time to time, in whole or in part, exchange, sell, surrender, release, subordinate, modify, waive, rescind, compromise or extend such security and may permit or consent to any such action or the result of any such action, and may apply such security and direct the order or manner of sale thereof; (e) any Secured Party may discharge or release, in whole or in part, any other Guarantor or any other Loan Party or other Person liable for the payment and performance of all or any part of the Secured Obligations, and may permit or consent to any such action or any result of such action, and shall not be obligated to demand or enforce payment upon any of the Collateral, nor shall any Secured Party be liable to any Guarantor for any failure to collect or enforce payment or performance of the Secured Obligations from any Person or to realize upon the Collateral, and (f) the Secured Parties may request and accept other guaranties of the Secured Obligations and any other indebtedness, obligations or liabilities of the Borrower or any other Loan Party to any Secured Party and may, from time to time, in whole or in part, surrender, release, subordinate, modify, waive, rescind, compromise or extend any such guaranty and may permit or consent to any such action or the result of any such action; in each case (a) through (f), as the Secured Parties may deem advisable, and without impairing, abridging, releasing or affecting this Section 2.

2.7 Reinstatement. The guarantee contained in this Section 2 shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Secured Obligations is rescinded or must otherwise be restored or returned by the Administrative Agent or any other Secured Party upon the insolvency, bankruptcy, dissolution, liquidation, examinership or

reorganization of the Borrower or any Guarantor, or upon or as a result of the appointment of a receiver, examiner, intervenor or conservator of, or trustee or similar officer for, the Borrower or any such Guarantor or any substantial part of its respective property, or otherwise, all as though such payments had not been made.

2.8 Payments. Subject to Section 2.20(a) of the Credit Agreement and the terms of any applicable Specified Swap Agreement, each Guarantor hereby guarantees that payments by it hereunder will be paid to the Administrative Agent without setoff or counterclaim in Dollars at the Funding Office.

Each Qualified ECP Guarantor hereby jointly and severally absolutely, unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each other Loan Party to honor all of its obligations under this Section 2 in respect of Secured Obligations under Specified Swap Agreements (provided that, each Qualified ECP Guarantor shall only be liable under this Section 2.9 for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this Section 2.9 or otherwise under this Agreement, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). The obligations of each Qualified ECP Guarantor under this Section 2.9 shall remain in full force and effect until Discharge of Obligations.

At the Administrative Agent’s request, after the occurrence and during the continuance of an Event of Default, each Grantor shall deliver to the Administrative Agent all original and other documents evidencing, and relating to, the agreements and transactions which gave rise to such Receivables, including, without limitation, all original orders, invoices and shipping receipts.

6.2 Communications with Obligors; Grantors Remain Liable.

or which would be inconsistent with or result in any violation of any provision of the Credit Agreement, this Agreement or any other Loan Document.

(b) If an Event of Default shall occur and be continuing and the Administrative Agent shall give notice of its intent to exercise such rights to the relevant Grantor or Grantors, (i) the Administrative Agent shall have the right (A) to receive any and all cash dividends, payments or other Proceeds paid in respect of the Investment Property (including the Pledged Collateral) of any or all of the Grantors and make application thereof to the Secured Obligations in the order set forth in Section 6.5, and (B) to exchange uncertificated Pledged Collateral for certificated Pledged Collateral and to exchange certificated Pledged Collateral for certificates of larger or smaller denominations, for any purpose consistent with this Agreement (in each case to the extent such exchanges are permitted under the applicable Pledged Collateral Agreements or otherwise agreed upon by the Issuer of such Pledged Collateral), (ii) any and all of such Investment Property shall be registered in the name of the Administrative Agent or its nominee, and (iii) the Administrative Agent or its nominee may exercise (x) all voting, corporate and other rights pertaining to such Investment Property at any meeting of shareholders of the relevant Issuer or Issuers or otherwise and (y) any and all rights of conversion, exchange and subscription and any other rights, privileges or options pertaining to such Investment Property as if it were the absolute owner thereof (including, without limitation, the right to exchange at its discretion any and all of any such Investment Property upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the corporate or other organizational structure of any Issuer, or upon the exercise by any Grantor or the Administrative Agent of any right, privilege or option pertaining to such Investment Property, and in connection therewith, the right to deposit and deliver any and all of such Investment Property with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Administrative Agent may determine), all without liability except to account for property actually received by it, but the Administrative Agent shall have no duty to any Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

(c) Each Grantor hereby authorizes and instructs each Issuer of any Pledged Collateral or Pledged Notes pledged by such Grantor hereunder to (i) comply with any instruction received by it from the Administrative Agent in writing that (x) states that an Event of Default has occurred and is continuing and (y) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from such Grantor, and each Grantor agrees that each Issuer shall be fully protected in so complying, and (ii) unless otherwise expressly permitted hereby, pay any dividends or other payments with respect to the Pledged Collateral or, as applicable, the Pledged Notes directly to the Administrative Agent.

(d) If an Event of Default shall have occurred and be continuing, the Administrative Agent shall have the right to apply the balance from any Deposit Account, Securities Account or Commodities Account or instruct the bank or intermediary, as applicable, at which any Deposit Account, Securities Account or Commodities Account is maintained to pay the balance of any such Deposit Account, Securities Account or Commodities Account to or for the benefit of the Administrative Agent.

6.4 Proceeds to be Turned Over To Administrative Agent.

the Administrative Agent in the exact form received by such Grantor (duly indorsed by such Grantor to the Administrative Agent, if required). All Proceeds received by the Administrative Agent hereunder shall be held by the Administrative Agent in a Collateral Account over which it maintains control, within the meaning of the UCC. All Proceeds while held by the Administrative Agent in a Collateral Account (or by such Grantor in trust for the Administrative Agent and the other Secured Parties) shall continue to be held as collateral security for the Secured Obligations, as applicable, and shall not constitute payment thereof until applied as provided in Section 6.5.

6.5 Application of Proceeds. If an Event of Default shall have occurred and be continuing, at any time at the Administrative Agent’s or Required Lender’s election (but subject to Section 8.3 of the Credit Agreement), the Administrative Agent may apply all or any part of Proceeds constituting Collateral realized through the exercise by the Administrative Agent of its rights hereunder, whether or not held in any Collateral Account, in payment of the Secured Obligations in accordance with Section 8.3 of the Credit Agreement.

6.6 UCC and Other Remedies. If an Event of Default shall occur and be continuing, the Administrative Agent, on behalf of the Secured Parties, may, and shall at the direction of Required Lenders, exercise, in addition to all other rights and remedies granted to them in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Secured Obligations, all rights and remedies of a secured party under the UCC or any other applicable law. Without limiting the generality of the foregoing, after the occurrence and during the continuance of an Event of Default, the Administrative Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law) to or upon any Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of the Administrative Agent or any other Secured Party or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Administrative Agent or any other Secured Party shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Grantor, which right or equity is hereby waived and released. Each Grantor further agrees, at the Administrative Agent’s request, to assemble the Collateral and make it available to the Administrative Agent at places which the Administrative Agent shall reasonably select, whether at such Grantor’s premises or elsewhere. The Administrative Agent shall apply the net proceeds of any action taken by it pursuant to this Section 6.6, in accordance with the provisions of Section 6.5, only after deducting all reasonable documented out-of-pocket costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Administrative Agent and the other Secured Parties hereunder, including, without limitation, reasonable documented out-of-pocket attorneys’ fees and disbursements, to the payment in whole or in part of the Secured Obligations, in such order as is contemplated by Section 8.3 of the Credit Agreement, and only after such application and after the payment by the Administrative Agent of any other amount required by any provision of law, including Section 9-615(a)(3) of the UCC, but only to the extent of the surplus, if any, owing to any Grantor. To the extent permitted by applicable law, each Grantor waives all claims, damages and demands it may acquire against the Administrative Agent or any other Secured Party arising out of the exercise by any of them of any rights hereunder, except to the extent caused by the gross negligence or willful misconduct

of the Administrative Agent or such Secured Party or their respective agents. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition. If an Event of Default has occurred and is continuing, Administrative Agent may, in addition to other rights and remedies provided for herein, in the other Loan Documents, the Specified Swap Agreements and the Cash Management Agreements, or otherwise available to it under applicable law and without the requirement of notice to or upon any Grantor or any other Person (which notice is hereby expressly waived to the maximum extent permitted by the Code or any other applicable law), (i) with respect to any Grantor’s Deposit Accounts in which Administrative Agent’s Liens are perfected by control under Section 9-104 or any other section of the UCC, instruct the bank maintaining such Deposit Account for the applicable Grantor to pay the balance of such Deposit Account to or for the benefit of the Administrative Agent for the payment of the Secured Obligations, and (ii) with respect to any Grantor’s Securities Accounts in which Administrative Agent’s Liens are perfected by control under Section 9-106 or any other section of the UCC, instruct the securities intermediary maintaining such Securities Account for the applicable Grantor to (A) transfer any cash in such Securities Account to or for the benefit of Administrative Agent for the payment of the Secured Obligations, or (B) liquidate any financial assets in such Securities Account that are customarily sold on a recognized market and transfer the cash proceeds thereof to or for the benefit of Administrative Agent. Each Grantor hereby acknowledges that the Secured Obligations arise out of a commercial transaction, and agrees that if an Event of Default shall occur and be continuing Administrative Agent shall have the right to an immediate writ of possession without notice of a hearing. Administrative Agent shall have the right to the appointment of a receiver for the properties and assets of each Grantor, and each Grantor hereby consents to such rights and such appointment and hereby waives any objection such Grantor may have thereto or the right to have a bond or other security posted by Administrative Agent.

6.7 Registration Rights.

(a) [Reserved].

(b) Each Grantor recognizes that the Administrative Agent may be unable to effect a public sale of any or all the Pledged Stock, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Grantor acknowledges and agrees that any such private sale may result in prices and other terms less favorable than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner. Subject to its compliance with state securities laws applicable to private sales. the Administrative Agent shall be under no obligation to delay a sale of any of the Pledged Stock for the period of time necessary to permit the Issuer thereof to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if such Issuer would agree to do so.

(c) Each Grantor agrees to use commercially reasonable efforts to do or cause to be done all such other acts as may be necessary to make such sale or sales of all or any portion of the Pledged Stock pursuant to this Section 6.7 valid and binding and in compliance with any applicable Requirement of Law. Each Grantor further agrees that a breach of any of the covenants contained in this Section 6.7 will cause irreparable injury to the Administrative Agent and the other Secured Parties, that the Administrative Agent and the other Secured Parties have no adequate remedy at law in respect

of such breach and, as a consequence, that each and every covenant contained in this Section 6.7 shall be specifically enforceable against such Grantor, and such Grantor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred under the Credit Agreement.

6.8 Intellectual Property License. Solely for the purpose of enabling the Administrative Agent to exercise rights and remedies under this Section 6 after the occurrence and during the continuation of an Event of Default, and at such time as the Administrative Agent shall be lawfully entitled to exercise such rights and remedies, each Grantor hereby grants to the Administrative Agent, for the benefit of the Secured Parties, an irrevocable, non-exclusive, worldwide license (exercisable without payment of royalty or other compensation to such Grantor), subject, in the case of Trademarks, to sufficient rights to quality control and inspection in favor of such Grantor to avoid the risk of invalidation of said Trademarks, to use, operate under, license, or sublicense any Intellectual Property, now owned or hereafter acquired by the Grantors following such time; provided, that, (i) so long as the Borrower has not received notice from the Administrative Agent that an Event of Default has occurred and is continuing, each Grantor shall retain the sole right to use all such Trademarks and (ii) the license granted pursuant to this Section 6.8 shall terminate immediately upon the Discharge of Obligations.

6.9 Deficiency. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay its Secured Obligations and the fees and disbursements of any attorneys employed by the Administrative Agent or any other Secured Party to collect such deficiency.

SECTION 7. THE ADMINISTRATIVE AGENT

Each Grantor covenants and agrees with the Administrative Agent and the other Secured Parties that:

7.1 Administrative Agent’s Appointment as Attorney-in-Fact, etc.

(a) Each Grantor hereby irrevocably constitutes and appoints the Administrative Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of such Grantor and in the name of such Grantor or in its own name, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement, and, without limiting the generality of the foregoing, after the occurrence and during the continuation of an Event of Default, each Grantor hereby gives the Administrative Agent the power and right, on behalf of such Grantor except as otherwise explicitly provided herein or required by law which cannot be legally waived, without notice to or assent by such Grantor, to do any or all of the following:

(i) in the name of such Grantor or its own name, or otherwise, take possession of and indorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due under any Receivable or with respect to any other Collateral and file any claim or take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Administrative Agent for the purpose of collecting any and all such moneys due under any Receivable or with respect to any other Collateral whenever payable;

(ii) in the case of any Intellectual Property which any Grantor has any right, title or interest, execute and deliver, and have recorded, any and all agreements, instruments, documents and papers as the Administrative Agent may request to evidence the Administrative Agent’s and the other Secured Parties’ security interest in such Intellectual Property and the goodwill and general intangibles of such Grantor relating thereto or represented thereby;

(iii) pay or discharge taxes and Liens levied or placed on or threatened against the Collateral, effect any repairs or any insurance called for by the terms of this Agreement and pay all or any part of the premiums therefor and the costs thereof;

Anything in this Section 7.1(a) to the contrary notwithstanding, the Administrative Agent agrees that it will not exercise any rights under the power of attorney provided for in this Section 7.1(a) unless an Event of Default shall have occurred and be continuing.

(b) If any Grantor fails to perform or comply with any of its agreements contained herein and such failure results in an Event of Default that is continuing, the Administrative Agent, at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement.

(c) The expenses of the Administrative Agent incurred in connection with actions undertaken as provided in this Section 7.1, together with interest thereon at a rate per annum equal to the highest rate per annum at which interest would then be payable on any category of past due ABR

Loans under the Credit Agreement, from the date of payment by the Administrative Agent to the date reimbursed by the relevant Grantor, shall be payable by such Grantor to the Administrative Agent on demand.

(d) Each Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. All powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement is terminated and the security interests created hereby are released.

7.2 Duty of Administrative Agent. The Administrative Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it in the same manner as the Administrative Agent deals with similar property for its own account. Neither the Administrative Agent, any other Secured Party nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on the Administrative Agent and the other Secured Parties hereunder are solely to protect the Administrative Agent’s and the other Secured Parties’ interests in the Collateral and shall not impose any duty upon the Administrative Agent or any other Secured Party to exercise any such powers. The Administrative Agent and the other Secured Parties shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct or resulting from a claim brought by any Grantor against Administrative Agent and the other Secured Parties for breach in bad faith of such party’s obligations hereunder, if such Grantor has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction.

7.3 Authority of Administrative Agent. Each Grantor acknowledges that the rights and responsibilities of the Administrative Agent under this Agreement with respect to any action taken by the Administrative Agent or the exercise or non-exercise by the Administrative Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement shall, as between the Administrative Agent and the other Secured Parties, be governed by the Credit Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Administrative Agent and the Grantors, the Administrative Agent shall be conclusively presumed to be acting as agent for the Secured Parties with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

SECTION 8. MISCELLANEOUS

8.1 Amendments in Writing. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except in accordance with Section 10.1 of the Credit Agreement.

8.2 Notices. All notices, requests and demands to or upon the Administrative Agent or any Grantor hereunder shall be effected in the manner provided for in Section 10.2 of the Credit Agreement; provided that any such notice, request or demand to or upon any Guarantor shall be addressed to such Guarantor at its notice address set forth on Schedule 1.

8.3 No Waiver by Course of Conduct; Cumulative Remedies. Neither the Administrative Agent nor any other Secured Party shall by any act (except by a written instrument pursuant to Section 8.1), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default, as applicable. No failure to exercise, nor any delay in exercising, on the part of the Administrative Agent or any other Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Administrative Agent or any other Secured Party of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Administrative Agent or such other Secured Party would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

8.4 Enforcement Expenses; Indemnification.

(a) Each Guarantor agrees to pay or reimburse the Administrative Agent and each other Secured Party for all its reasonable and documented out-of-pocket costs and expenses incurred in collecting against such Guarantor under the guaranty contained in Section 2 of this Agreement or otherwise enforcing or preserving any rights against such Guarantor under this Agreement, the other Loan Documents, the Specified Swap Agreements and the Cash Management Agreements to which such Guarantor is a party, including the reasonable and documented out-of-pocket fees and disbursements of counsel to the same extent required of the Borrower under Section 10.5 of the Credit Agreement.

(b) Each Grantor agrees to pay, and to save the Administrative Agent and each other Secured Party harmless from, any and all liabilities with respect to, or resulting from any delay in paying, any and all stamp, excise, sales or other taxes which may be payable or determined to be payable with respect to any of the Collateral or in connection with any of the transactions contemplated by this Agreement to the same extent the Borrower would be required to do so pursuant to the Credit Agreement. Any such payment pursuant to the preceding sentence shall appropriately reduce the Borrower’s obligation to make such payment under the Credit Agreement.

(c) Each Guarantor agrees to pay, and to save the Administrative Agent and each other Secured Party harmless from, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement to the extent the Borrower would be required to do so pursuant to the Credit Agreement. Any such payment pursuant to the preceding sentence shall appropriately reduce the Borrower’s obligation to make such payment under the Credit Agreement.

The Administrative Agent and each Secured Party shall endeavor to notify such Grantor promptly of any set-off and the application made by the Administrative Agent or such Secured Party of the proceeds thereof; provided that the failure to provide such notice shall not affect the validity of such set-off and application. The rights of the Administrative Agent and each other Secured Party under this Section 8.6 are in addition to other rights and remedies (including, without limitation, other rights of setoff) which the Administrative Agent or such other Secured Party may have.

8.7 Counterparts. This Agreement may be executed and delivered by one or more of the parties to this Agreement on any number of separate counterparts (including delivery by facsimile and/or electronic mail, which shall be effective as delivery of an original executed counterpart hereof), and all of said counterparts taken together shall be deemed to constitute one and the same instrument.

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