As soon as practicable after 10:00 a.m. (New York time) on the LIBOR Interest Rate Determination Date, the Administrative Agent shall determine (which determination shall, absent manifest error, be presumptively correct) the interest rate for the LIBOR Loans for which an interest rate is then being determined and shall promptly give notice thereof (in writing or by telephone confirmed in writing) to the applicable Borrower. In the event that on any LIBOR Interest Rate Determination Date the Administrative Agent shall have determined (which determination shall, absent manifest error, be presumptively correct and binding upon all parties) that:

(1) adequate and fair means do not exist for ascertaining the applicable interest rates by reference to which the LIBO Rate then being determined is to be fixed; or

(2) the LIBO Rate for any Interest Period for such Loans will not adequately reflect the cost to any Lender of making, funding or maintaining its LIBOR Loan for such Interest Period, the Administrative Agent shall forthwith so notify the applicable Borrower and the Lender, whereupon:

(A) each LIBOR Loan will automatically, on the last day of the then existing Interest Period therefor, convert into a Base Rate Loan; and

(B) the obligation of the Lenders to make, or to convert Loans into, LIBOR Loans shall be suspended until the Administrative Agent shall notify the applicable Borrower and the Lenders that the circumstances causing such suspension no longer exist.

(c) Illegality. Notwithstanding any other provision of this Agreement, if any Lender shall notify the Administrative Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or any central bank or other Governmental Authority asserts that it is unlawful, for any Lender to perform its obligations hereunder to make LIBOR Loans or to fund or maintain LIBOR Loans hereunder, (i) the obligation of the Lenders to make, or to convert Loans into or to continue Loans as, LIBOR Loans shall be suspended until the Administrative Agent shall notify the Borrowers and the Lenders that the circumstances causing such suspension no longer exist and (ii) the Borrowers shall on the termination of the Interest Period then applicable thereto, or on such earlier date required by law, prepay in full all LIBOR Loans then outstanding together with accrued interest thereon, or convert all such LIBOR Loans into Base Rate Loans in accordance with Section 2.06.

(d) Compensation. In addition to such amounts as are required to be paid by the Borrowers pursuant to the other Sections of this Article II, the Borrowers agree to compensate any Lender for all losses, expenses and liabilities, including, without limitation, any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund or maintain such Lender’s LIBOR Loans to the Borrowers, which such Lender may sustain (i) if for any reason a funding of any LIBOR Loans does not occur on a date specified therefor in a Notice of Borrowing or Notice of Conversion/Continuation, or a successive Interest Period does not commence after notice therefor is given pursuant to Section 2.06, (ii) if any voluntary or mandatory prepayment of any LIBOR Loans occurs for any reason on a date which is not the last scheduled day of an Interest Period, (iii) as a consequence of any required conversion of LIBOR Loans to Base Rate Loans as a result of any of the events indicated in Section 2.07(d), or (iv) as a consequence of any other failure by a Borrower to repay LIBOR Loans when required by the terms of this Agreement.

(e) Booking of LIBOR Loans. The Lenders may make, carry or transfer LIBOR Loans at, to, or for the account of, any of their respective branch offices or the office of any of their respective affiliates.

(f) LIBOR Loans After Event of Default. Unless the Requisite Lenders shall otherwise agree, after the occurrence of and during the continuance of any Event of Default, the Borrowers may not borrow Loans as LIBOR Loans or elect to have any Loans continued as, or converted to, LIBOR Loans after the expiration of any Interest Period then in effect for such Loans.

(a) Interest on each LIBOR Loan shall be payable in arrears on each LIBOR Interest Payment Date for such LIBOR Loan and upon payment in full thereof. Interest on each Base Rate Loan shall be payable quarterly in arrears on each Payment Date and upon payment in full thereof. After the occurrence and during the continuance of any Event of Default, interest shall be payable on demand.

(b) Subject to the provisions of Sections 2.09 and 9.02, the outstanding principal balance of the Term Loans, other than the Term B Loan Deferral Amount, shall be payable in eighteen quarterly installments commencing on March 31, 2004, and continuing on

the last day of each June, September, December and March thereafter through and including the Term Loan Termination Date with (i) each such quarterly installment payable during the period March 31, 2004 through and including December 31, 2005 in an amount equal to $5,000,000 multiplied by a fraction equal to the quotient of the difference between the outstanding Term Loans on the Closing Date and the Term B Loan Deferral Amount divided by the sum of the outstanding Term A Loans and Term B Loans on the Closing Date, (ii) each subsequent quarterly installment other than the last one in the amount of $5,000,000, and (iii) the last such quarterly installment to be in an amount equal to the then remaining unpaid portion of the Term Loans. Subject to the provisions of Sections 2.09 and 9.02, if the Additional Deferral Conditions are not satisfied on December 31, 2005, the Term B Loan Deferral Amount shall be payable in four equal quarterly installments commencing on March 31, 2006, and continuing on the last day of June, September and December thereafter through and including December 31, 2006 with each such quarterly installment in an amount equal to twenty-five percent (25%) of the Term B Loan Deferral Amount. In the event that the Additional Deferral Conditions are satisfied on December 31, 2005, the Term B Loan Deferral Amount shall be payable in ten equal quarterly installments commencing on March 31, 2006, and continuing on the last day of each June, September, December and March thereafter through and including the Term Loan Termination Date, with each such quarterly installment in an amount equal to ten percent (10%) of the Term B Loan Deferral Amount.

(c) Payments made with respect to the Loans by each Borrower shall be applied by the Administrative Agent first to unpaid and accrued fees and interest and then to the outstanding unpaid principal balance of the Loans of such Borrower; provided, however, that upon the occurrence and during the continuance of an Event of Default, all payments and prepayments with respect to the Obligations and all proceeds of Collateral shall be applied in the following order by the Administrative Agent; provided, further, that the order of priority set forth in the following clauses may be altered upon direction from the Requisite Lenders to the Administrative Agent:

(1) first, to pay Obligations in respect of any expenses then due and payable by the Borrowers to the Administrative Agent or the Lenders or any Person which is not a Lender that has issued a Letter of Credit

(2) second, to pay Obligations in respect of any reimbursement or indemnities then due and payable to the Administrative Agent or the Lenders or any Person which is not a Lender that has issued a Letter of Credit (excluding any reimbursement obligations with respect to any Letters of Credit);

(3) third, to pay Obligations in respect of any fees due and owing to the Administrative Agent;

(4) fourth, to pay Obligations in respect of the commitment fee and any other fees and commissions then due and owing to the Administrative Agent, the Collateral Agent or the Lenders or any Person which is not a Lender that has issued a Letter of Credit;

(5) fifth, to pay Obligations in respect of any accrued and unpaid interest due in respect of Loans and Letter of Credit Obligations;

(6) sixth, to the ratable payment or prepayment of principal of any outstanding Loans and reimbursement obligations with respect to Letters of Credit;

(7) seventh, to pay termination payments due and payable pursuant to any Interest Rate Agreement or hedging agreement to which any Lender or its affiliate is a counterparty; and

SECTION 2.09. Optional and Mandatory Prepayment of Loans; Optional and Mandatory Reduction of Commitment Amount.

(a) Provided that no Event of Default has occurred and is continuing, the Borrowers shall have the right upon the provision of (1) twenty-five days’ prior written notice on or prior to the six month anniversary of the Closing Date to the Administrative Agent, and (2) forty-five days’ prior written notice to the Administrative Agent at any time thereafter, which notice, once given, shall be irrevocable, on any Payment Date with respect to any Base Rate Term Loans and on the last day of the applicable Interest Period with respect to any LIBOR Term Loans, to prepay the outstanding principal thereof in a minimum principal amount of $1,000,000 and increments of $500,000 in excess thereof, together in each case with accrued interest thereon as determined on the date of such prepayment.

(b) Upon the occurrence of any Event of Loss with respect to any item of Collateral that is not repaired or replaced within 180 days after the occurrence of such Event of Loss (other than an item of Collateral no longer used or useful in the Business), the Borrowers shall make a principal prepayment in an amount equal to the replacement value of the item of Collateral which suffered the Event of Loss, together with accrued interest thereon with such principal payments to be applied, pro rata, to the outstanding principal balance of the Revolving Loans and the Term Loans.

(c) Simultaneously with the delivery of the financial statements required to be delivered under Section 5.06(a) for the fiscal years ending December 31, 2002 and thereafter, the Revolving Loan Commitment Amounts of all the Lenders shall be permanently reduced and the outstanding principal balance of the Term Loans shall be prepaid on a pro rata basis (together with accrued and unpaid interest on the Term Loans being prepaid) in an amount equal to fifty percent (50%) of Excess Cash Flow, if any, as determined for such fiscal year; provided, however, that such reduction in the Revolving Loan Commitment Amounts and prepayment of the Term Loans shall not be required with respect to any fiscal year in which the Borrowers maintained throughout such fiscal year an Operating Leverage Ratio of less than 5.0 to 1.0.

(d) The Revolving Loan Commitment Amounts of all the Lenders shall be permanently reduced and the outstanding principal balance of the Term Loans shall be prepaid on a pro rata basis in an amount equal to (i) all of the net proceeds of any sales of assets of any Borrower other than sales to another Borrower or otherwise made in the ordinary course of business, which proceeds are not reinvested within 180 days after receipt thereof in replacement assets, plus accrued interest thereon, and (ii) the proceeds of insurance policies and condemnation awards paid to any Borrower if the proceeds thereof are not applied within 180

days after such payment to the replacement, reconstruction or restoration of equipment which was the subject of the insurance loss or award, plus accrued interest thereon.

(e) The Revolving Loan Commitment Amount of all the Lenders, other than the Deferral Lenders, shall be reduced (i) on each Payment Date during the period March 31, 2004 through and including December 31, 2005, in an aggregate amount equal to $2,750,000 multiplied by a fraction equal to the quotient of the difference between the aggregate Revolving Loan Commitment Amount of all Lenders on the Closing Date and the Revolving B Loan Commitment Reduction Deferral Amount, divided by the aggregate Revolving Loan Commitment Amount of all Lenders on the Closing Date, and (ii) on each Payment Date thereafter by $2,750,000. If the Additional Deferral Conditions are not satisfied on December 31, 2005, then the Revolving Loan Commitment Amount of the Deferral Lenders shall be reduced on the Payment Dates occurring on March 31, 2006, June 30, 2006, September 30, 2006 and December 31, 2006 in an amount equal to twenty-five percent (25%) of the Revolving B Loan Commitment Reduction Deferral Amount on each such Payment Date. In the event that the Additional Deferral Conditions are satisfied on December 31, 2005, then the Revolving Loan Commitment Amount of the Deferral Lenders shall be reduced on the Payment Dates occurring on March 31, 2006 through and including June 30, 2008 in an amount equal to ten percent (10%) of the Revolving B Loan Commitment Reduction Deferral Amount on each such Payment Date. The Revolving Loan Commitment Amount of all Lenders shall be reduced to zero on the Revolving Loan Commitment Termination Date.

(f) On each date that the Revolving Loan Commitment Amount is reduced, the Borrowers shall prepay first, the Revolving Loans, and second, provide to the Administrative Agent cash collateral with respect to the Letter of Credit Obligations in such amounts such that the sum of the outstanding principal balance of the Revolving Loans plus the Letter of Credit Obligations does not exceed the Revolving Loan Commitment Amount of all the Revolving Lenders after giving effect to the reduction thereof effective on such date. Any reduction in the Revolving Loan Commitment Amount of all the Lenders shall be allocated to each Revolving Lender based on its Pro Rata Share. All prepayments of principal shall be applied to the remaining principal payments of the type of Loans prepaid in the inverse order of maturity. The Letter of Credit Obligations shall be reduced on a dollar-for-dollar basis by the cash collateral.

(g) Each prepayment of the Loans made by the Borrowers under this Agreement, whether voluntary or mandatory, shall be applied to the remaining principal payments of the type of Loans prepaid (and in the inverse order of maturity with respect to Term Loans) and shall be accompanied by payment of accrued and unpaid interest thereon and any compensation payable under Section 2.07(d).

(a) Agreement to Issue. Subject to the terms and conditions of this Agreement, and in reliance upon the representations and warranties of the Borrowers herein set forth, the Administrative Agent agrees to issue Letters of Credit for the respective accounts of the Borrowers in accordance with this Section 2.10 from time to time during the term of this Agreement.

Whenever the Administrative Agent receives a payment from a Borrower on account of reimbursement obligations in respect of a Letter of Credit as to which the Administrative Agent has previously received for its account payment from a Revolving Lender pursuant to this Section 2.10(f)(2), the Administrative Agent shall promptly pay to such Lender such

Revolving Lender’s Pro Rata Share of such payment from such Borrower in Dollars. Each such payment shall be made by the Administrative Agent on the Business Day on which the Administrative Agent receives immediately available funds paid to such Person pursuant to the immediately preceding sentence, if received prior to 11:00 a.m. (New York time) on such Business Day and otherwise on the next succeeding Business Day.

respective Pro Rata Shares of such amount set aside, avoided or recovered, together with interest at the rate required to be paid by the Administrative Agent upon the amount required to be repaid by it.

(a) The Borrowers shall be jointly and severally liable to pay the Administrative Agent for the account of the Lenders a nonutilization fee payable on each Payment Date occurring during the period commencing on the Closing Date through and including the Payment Date immediately after the Revolving Loan Commitment Termination Date based upon the applicable per annum rate set forth below (calculated based on a 365-day year and payable quarterly) on the undrawn portion of the Commitment Amount during the quarterly period ending on such Payment Date:

(b) The Borrowers shall be jointly and severally liable to pay the Administrative Agent the administrative agency fee set forth in the Fee Letter referred to in clause (ii) of the definition thereof at the times and in the amounts so specified in such letter.

(a) All payments by the Borrowers hereunder and under the Notes shall be made to the Administrative Agent by wire transfer or other electronic payment method to the Payment Account, or to such bank account as the Administrative Agent may designate, for the account of the Lenders in Dollars in immediately available funds by 12:00 p.m., New York time, on the date on which such payment shall be due. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest or other fees ratably (other than amounts payable pursuant to Section 2.14) to each Lender in accordance with Section 10.07 hereof. Interest in respect of any Loan hereunder shall accrue from the day such Loan is made up to and including the day prior to the date on which such Loan is paid in full. Payments received after 12:00 p.m. shall not be given credit until the next Business Day, and the Borrowers shall be liable for interest, if any, accruing on such payment until the next Business Day

(1) Any and all payments by each Borrower hereunder shall be made free and clear of and without deduction for any and all Taxes. If any Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under the other Loan Documents to any Lender or the Administrative Agent, (A) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.12) such Lender or the Administrative Agent receives an amount equal to the sum it would have received had no such deductions been made, (B) such Borrower shall make such deductions, and (C) such Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law and within thirty (30) days after the date of any such payment, such Borrower will furnish to the Administrative Agent, at its address referred to in Section 11.01, the original or a certified copy of a receipt evidencing payment thereof. If a withholding tax of the United States of America or any other Governmental Authority shall be or become applicable (y) after the date of this Agreement, to the payments by any Borrower made to the Lending

Office or any other office that a Lender may claim as its Lending Office, or (z) after such Lender’s selection and designation of any other Lending Office, to such payments made to such other Lending Office, such Lender shall use reasonable efforts to make, fund and maintain its Loans through another Lending Office of such Lender in another jurisdiction so as to reduce, but not increase, the applicable Borrower’s liability hereunder, if the making, funding or maintenance of such Loans through such other Lending Office of such Lender is not, in the judgment of such Lender, disadvantageous to such Lender. Notwithstanding anything to the contrary hereunder, if a Person becomes a Lender under this Agreement pursuant to Section 11.08 hereof, the Borrowers shall in no event be required to increase any payment pursuant to paragraph (b) of this Section 2.12 by an amount that would exceed the amount of any increase that would be required to be made under paragraph (b) of this Section 2.12 to the assigning Lender.

(2) The Borrowers will jointly and severally indemnify each Lender and the Administrative Agent and hold them harmless for the full amount of Taxes (including, without limitation, any Taxes imposed by any Governmental Authority on amounts payable under this Section 2.12 or any other documentary taxes, assessments or charges made by any Governmental Authority by reason of the execution and delivery of this Agreement or any other Loan Document) paid by such Lender or the Administrative Agent (as the case may be) and any liability (including penalties, interest, and expenses) arising therefrom or with respect thereto. This indemnification shall be made within thirty (30) days after the date such Lender or the Administrative Agent (as the case may be) makes written demand therefor. A certificate as to any additional amount payable to any Lender or the Administrative Agent under this Section 2.12 submitted to the Borrowers and the Administrative Agent (if a Lender is so submitting) by such Lender or the Administrative Agent shall show in reasonable detail the amount payable and the calculations used to determine such amount, and shall be conclusive and binding, absent manifest error. With respect to such deduction or withholding for or on account of any Taxes and to confirm that all such Taxes have been paid to the appropriate Governmental Authorities, the applicable Borrower shall promptly (and in any event not later than thirty (30) days after receipt) furnish to each Lender and the Administrative Agent such certificates, receipts and other documents as may be required (in the judgment of such Lender or the Administrative Agent) to establish any tax credit to which such Lender or the Administrative Agent may be entitled.

(3) Without prejudice to the survival of any other agreement of any Borrower hereunder, the agreements and obligations of such Borrower contained in this Section 2.12 shall survive the payment in full of principal and interest hereunder and the termination of this Agreement.

(4) Without limiting the obligations of the Borrowers under this Section 2.12, each Lender that is not created or organized under the laws of the United States of America or a political subdivision thereof shall deliver to the Borrowers and the Administrative Agent on or before the effective date hereof, or, if later, the date on which such Lender becomes a Lender pursuant to Section 11.08 hereof, a true and accurate certificate executed in duplicate by a duly authorized officer of such Lender, in a form satisfactory to the Borrowers and the Administrative Agent, to the effect that such Lender is capable under the provisions of an applicable tax treaty concluded by the United States

of America (in which case the certificate shall be accompanied by two original, executed copies of Form W-8 BEN of the IRS) or under Section 1442 of the IRC (in which case the certificate shall be accompanied by two original, executed copies of Form W-8 ECI of the IRS) of receiving payments of interest hereunder exempt from or at a reduced deduction or withholding of United States federal income tax or that such Lender is not a bank described in Section 881(c)(3)(A) of the IRC (in which case the certificate should be accompanied by two original, executed copies of Form W-8 or W-9 of the IRC). Each such Lender further agrees to deliver to the Borrowers and the Administrative Agent from time to time a true and accurate certificate executed in duplicate by a duly authorized officer of such Lender substantially in a form satisfactory to the Borrowers and the Administrative Agent, before or promptly upon the occurrence of any event requiring a change in the most recent certificate previously delivered by it to the Borrowers and the Administrative Agent pursuant to this Section 2.12(b)(4). Further, each Lender which delivers a certificate accompanied by Form W-8 BEN of the IRS covenants and agrees to deliver to the Borrowers and the Administrative Agent within fifteen (15) days prior to the Closing Date, and every third anniversary of such date thereafter, on which this Agreement is still in effect, another such certificate and two accurate and complete original signed copies of Form W-8 BEN (or any successor form or forms required under the IRC or the applicable regulations promulgated thereunder), and each Lender that delivers a certificate accompanied by Form W-8 ECI of the IRS covenants and agrees to deliver to the Borrowers and the Administrative Agent within fifteen (15) days prior to the beginning of each subsequent taxable year of such Lender during which this Agreement is still in effect, another such certificate and two accurate and complete original signed copies of IRS Form W-8 ECI (or any successor form or forms required under the IRC or the applicable regulations promulgated thereunder). Each such certificate shall certify as to one of the following:

(A) that such Lender is capable of receiving payments of interest hereunder exempt from or at a reduced deduction or withholding of United States of America federal income tax;

(B) that such Lender is not capable of receiving payments of interest hereunder exempt from or at a reduced deduction or withholding of United States of America federal income tax as specified therein but is capable of recovering the full amount of any such deduction or withholding from a source other than the Borrowers and will not seek any such recovery from the Borrowers; or

(C) that, as a result of the adoption of or any change in any law, treaty, rule, regulation, guideline or determination of a Governmental Authority or any change in the interpretation or application thereof by a Governmental Authority after the date such Lender became a party hereto, such Lender is not capable of receiving payments of interest hereunder without deduction or withholding of United States of America federal income tax as specified therein and that it is not capable of recovering the full amount of the same from a source other than the Borrowers.

Each Lender shall promptly furnish to the Borrowers and the Administrative Agent such additional documents as may be reasonably required by the Borrowers or the Administrative Agent to establish any exemption from or reduction of any Taxes required to be deducted or withheld and which may be obtained without undue expense to such Lender.

(5) For a period with respect to which a Lender has failed to provide the Administrative Agent and the Borrowers with the appropriate form described in Section 2.12(b)(4) (other than if such failure is due to a change in law occurring subsequent to the date on which a form originally was required to be provided), such Lender shall not be entitled to indemnification under this Section 2.12 with respect to Taxes imposed by the United States by reason of such failure; provided, however, that should a Lender become subject to Taxes because of its failure to deliver a form required hereunder, the Borrowers shall take such steps as such Lender shall reasonably request to assist such Lender to recover such Taxes.

(1) If a Borrower pays any additional amount under this Section 2.12 and, as a result, any Lender, together with the Administrative Agent, subsequently, in their sole discretion and based on their own interpretation of any relevant laws (but acting in good faith) receive or are granted a final and non-appealable credit against or deduction from or in respect of any tax payable by such Lender, or obtain any other final and non-appealable relief in respect of any tax, which in the opinion of such Lender and the Administrative Agent, acting in good faith, is both reasonably identifiable and quantifiable by them without requiring any Lender, the Administrative Agent or their professional advisers to expend a material amount of time or incur a material cost in so identifying or quantifying (any of the foregoing, to the extent so reasonably identifiable and quantifiable, being referred to as a “Saving”), such Lender shall, to the extent that it can do so without prejudice to the retention of the Saving, reimburse such Borrower promptly after such identification and quantification with the amount of such Saving; provided, however, that any such Saving shall be reduced by any costs incurred by such Lender or the Administrative Agent in obtaining such Saving.

(2) Nothing in this Section 2.12(c) shall require any Lender to disclose to any Person any information regarding its tax affairs or to arrange its tax and other affairs in any particular manner.

SECTION 2.13. Maximum Lawful Interest Rate. Notwithstanding any provision contained herein, the total liability of the Borrowers for payment of interest pursuant hereto and the Notes, including any other charges or other amounts, to the extent such charges and other amounts are deemed to be interest, shall not exceed the maximum amount of such interest permitted by law to be charged, collected, or received from the Borrowers (the “Maximum Rate”). If any payments by any Borrower for the account of any Lender include interest in excess of the Maximum Rate, such Lender shall apply such excess to the reduction of the unpaid principal amount owing by such Borrower, or if none is due, such excess shall be returned to such Borrower.

(a) Increased Costs. If, due to either (i) the introduction after the date hereof of, or any change after the date hereof in or in the interpretation of, any applicable law, rule or regulation by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof or (ii) compliance by any Lender after the date hereof with any final request or final directive issued after the date hereof (whether or not having the force of law) by any such Governmental Authority, central bank or comparable agency, and, as a result of any of the events set forth in the above clauses (i) and (ii), (x) there shall be any increase in the cost to such Lender in maintaining its Commitment under this Agreement, funding or maintaining its Pro Rata Share of the Loans under this Agreement or maintaining its commitment to participate (as provided for in Section 2.10(f)) in any Letter of Credit in connection with the issuance of any Letter of Credit or other commitments of this type, or (y) any Lender is subjected to any charge or withholding on its obligations hereunder, or changes in the basis of taxation of payments to any Lender in connection with any of the foregoing (except for changes in the rate of tax on overall net income of any Lender) (collectively, “Increased Costs”), then the Borrowers shall, from time to time, pay, to the Administrative Agent for the benefit of such Lender within 15 days after such Lender shall have provided notice to the Administrative Agent (and the Administrative Agent shall have provided notice to the Borrowers) of such Increased Cost, an amount sufficient to compensate such Lender for such Increased Cost, as provided herein. A certificate setting forth in reasonable detail the computation of the amount of such Increased Cost (which increase in cost shall be determined by such Lender’s reasonable allocation of the aggregate of such cost increases resulting from such event), submitted to the Borrowers by such Lender, shall be conclusive and binding for all purposes, absent manifest error.

(b) Increased Capital. If any Lender which is subject to minimum capital requirements determines that compliance by such Lender, with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender, or any corporation controlling such Lender, and such Lender reasonably determines that the amount of such capital is increased by or based upon any commitment to lend hereunder or making or maintaining Loans, its commitment to participate (as provided for in Section 2.10(f)) in any Letter of Credit in connection with the issuance of any Letter of Credit or other commitments of this type, then, upon demand by such Person, the Borrowers agree to, within five (5) days of such demand, pay to such Person, from time to time as specified by such Person, additional amounts sufficient to compensate such Person in the light of such circumstances, to the extent that such Person reasonably determines such increase in capital to be allocable to such Person’s commitment or maintenance of Loans hereunder or such Person’s commitment to participate in any Letter of Credit. A certificate as to the amount of such increased cost, submitted to the Borrowers by the applicable Person shall, absent manifest error, be conclusive and binding on the Borrowers for all purposes.

(a) Notwithstanding anything to the contrary in this Agreement or the other Loan Documents, all payment and performance Obligations arising under this Agreement and the other Loan Documents shall be joint and several obligations of each Borrower secured by all

the Collateral. The Administrative Agent and the Collateral Agent may apply any portion of any Collateral to satisfy any of the Obligations of any other Borrower.

(b) Contribution and Indemnification between the Borrowers. To the extent that any Borrower shall, as a result of the operation of Section 2.15, pay (whether directly or by the application of proceeds of Collateral owned by such Borrower) any Obligation of any other Borrower under the Loan Documents (such payment being referred to as an “Accommodation Payment”), then such Borrower shall be entitled to contribution and indemnification from, and be reimbursed by each other Borrower, in an amount equal to a fraction of such Accommodation Payment, the numerator of which fraction is such other Borrower’s “Allocable Amount” (as defined below) and the denominator of which is the sum of the Allocable Amounts of all the Borrowers. As of any date of determination, the “Allocable Amount” of each Borrower shall be equal to the maximum amount of liability for Accommodation Payments which could be asserted against such Borrower hereunder without (a) rendering such Borrower “insolvent” within the meaning of Section 101(32) of the United States Bankruptcy Code (11 U.S.C. §101 et. seq) (the “Bankruptcy Code”), Section 2 of the Uniform Fraudulent Transfer Act (the “UFTA”) or Section 2 of the Uniform Fraudulent Conveyance Act (the “UFCA”), (ii) leaving such Borrower 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 (iii) leaving such Borrower 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. All rights and claims of subrogation, contribution, indemnification and reimbursement under this section shall be subordinate in right of payment to the prior payment in full of the Obligations. Each Borrower agrees that any extension, forbearance or amendment, or any acceptance, release or substitution of security, or any impairment or suspension of the Administrative Agent’s, the Collateral Agent’s or the Lenders’ remedies or rights against any other Borrower or the cessation of the liability of any other Borrower for any reason other than full and indefeasible satisfaction of all Obligations shall not in any way affect the liability of such Borrower. Each Borrower has provided itself of the means of remaining informed of the financial condition of each other Borrower, and waives any right to require any Lender or the Administrative Agent to keep it informed of the financial condition of any other Borrower. The provisions of this section shall, to the extent expressly inconsistent with any provision in any Loan Document, supersede such inconsistent provision.

Each Borrower represents and warrants to the Administrative Agent, the Collateral Agent and the Lenders that:

(a) Such Borrower (i) is a corporation or limited liability company duly organized, validly existing and in good standing under the laws of its jurisdiction of organization and (ii) is qualified to do business in the jurisdiction in which its principal place of business is located and in every other jurisdiction where such qualification is necessary unless the failure to

(c) do not result in the creation or imposition of any Lien of any nature whatsoever upon any property or assets of such Borrower other than the Liens granted pursuant to this Agreement or the other Loan Documents;

As of the date of the Financials, (a) the Financials fairly represent the Guarantor’s financial position and results of operations; and (b) there are no omissions from the

SECTION 3.06. Tax Returns. Except as set forth on Schedule 3.06 hereto, such Borrower has filed or caused to be filed all Federal, state and local tax returns which are required to be filed and has paid or caused to be paid all taxes as shown on such returns or on any assessment received by it to the extent that such taxes have become due, except such taxes the amount, applicability or validity of which are being contested in good faith by appropriate proceedings and with respect to which such Borrower shall have set aside on its books adequate reserves with respect to such taxes as are required by GAAP.

SECTION 3.07. No Defaults. Such Borrower is not in default (i) with respect to any judgment, writ, injunction, decree, rule or regulation of any Governmental Authority which is likely to have a Material Adverse Effect, or (ii) in the performance, observance or fulfillment of any of the obligations, covenants or conditions contained in any material agreement or instrument to which such Borrower is a party or by which any of its assets are bound, which is likely to have a Material Adverse Effect.

All of the foregoing agreements are valid, subsisting and in full force and effect and none of such Borrower, or, to the best of such Borrower’s knowledge and belief, any other parties, are in material default thereunder. Such Borrower has given true and complete copies of all such agreements to the Administrative Agent and the Lenders.

Each Plan which is intended to be qualified under Section 401(a) of the IRC has been determined by the IRS to be so qualified, and each trust related to any such Plan has been determined to be exempt from federal income tax under Section 501(a) of the IRC. Except as disclosed on Schedule 3.11, none of such Borrower or any ERISA Affiliate maintains or contributes to any employee welfare benefit plan within the meaning of Section 3(1) of ERISA which provides benefits to employees after termination of employment other than as required by Section 601 of ERISA.

Upon filing such financing statements, to the extent that the filing of a financing statement is sufficient to perfect a security interest, no further action is required to perfect the Liens of the Collateral Agent in favor of the Lenders in the Collateral of such Borrower described in Section 8.01.

having jurisdiction with respect thereto, revoking, or deciding not to renew, any such Governmental Approval, occur upon the issuance of such order, and, in the case of any other order revoking or terminating any of the Governmental Approvals or deciding not to renew such Governmental Approvals prior to the termination thereof, occur when such order becomes final; or

(j) the FCC, any PUC or any other Governmental Authority, by final order, determines that the existence or performance of this Agreement or any other Loan Document will result in a revocation, suspension or material adverse modification of any of the Governmental Approvals for any System; or

SECTION 9.02. Termination of Commitment; Acceleration. Upon the occurrence and at any time during the continuance of any Event of Default, the Administrative Agent may upon direction from the Requisite Lenders:

(a) by notice to the Borrowers, terminate Lenders’ Commitment to make Loans hereunder; or

(b) by notice to the Borrowers, declare the Obligations to be immediately due and payable, whereupon all the Obligations shall be immediately due and payable without further notice of any kind, provided, however, that if an Event of Default described in Section 9.01(f) shall exist or occur, all of the Obligations shall automatically, without declaration or notice of any kind, be immediately due and payable and the Commitment shall be automatically terminated.

SECTION 9.03. Waivers. Demand, presentment, protest and notices of nonpayment, protest, dishonor and acceptance are hereby waived by each Borrower. Each Borrower also waives the benefit of all valuation, appraisal and exemption laws and the posting of any bond required of the Administrative Agent, the Collateral Agent or any Lender in connection with any judicial process to realize on the Collateral, to enforce any judgment or other court order entered in favor of the Administrative Agent, the Collateral Agent or any Lender or to enforce by specific performance, temporary restraining order, or preliminary or permanent injunction, this Agreement or any other Loan Documents. Each Borrower waives the right, if any, to the benefit of, or to direct the application of, any Collateral. Each Borrower hereby acknowledges that none of the Administrative Agent, the Collateral Agent or any Lender has any obligation to resort to any Collateral or make claim against any other Person before seeking payment or performance from any Borrower.

SECTION 9.04. Rights and Remedies Generally. If an Event of Default occurs and is continuing, the Administrative Agent and the Collateral Agent shall have, in addition to any other rights and remedies contained in this Agreement or in any of the other Loan Documents, all of the rights and remedies of a secured party under the Code or other applicable laws, all of which rights and remedies shall be cumulative, and none exclusive, to the extent permitted by law. In addition to all such rights and remedies, the sale, lease or other disposition of the Collateral, or any part thereof, by the Administrative Agent or the Collateral Agent after the occurrence of an Event of Default may be for cash, credit or any combination thereof, and the Administrative Agent or the Collateral Agent may purchase all or any part of the Collateral at public or, if permitted by law, private sale, and in lieu of actual payment of such purchase price, may set off the amount of such purchase price against the Obligations then owing. Any sales of the Collateral may be adjourned from time to time with or without notice. The Administrative Agent or the Collateral Agent may, in its sole discretion, cause the Collateral to remain on the premises of any Borrower, at the expense of the Borrowers, pending sale or other disposition of the Collateral. The Administrative Agent or the Collateral Agent shall have the right to conduct such sales on the premises of any Borrower, at the expense of the Borrowers, or elsewhere, on such occasion or occasions as it may see fit.

SECTION 9.05. Entry Upon Premises and Access to Information. If an Event of Default occurs and is continuing, the Administrative Agent and the Collateral Agent shall have

the right to enter upon the premises of any Borrower where any Collateral is located (or is believed to be located) without any obligation to pay rent to such Borrower, or any other place or places where the Collateral is believed to be located and kept, and render the Collateral unusable or remove the Collateral therefrom to the premises of the Administrative Agent or the Collateral Agent or any agent thereof, for such time as the Administrative Agent or the Collateral Agent may desire, in order effectively to collect or liquidate the Collateral, and/or the Administrative Agent or the Collateral Agent may require any Borrower to assemble the Collateral and make it available to the Administrative Agent or the Collateral Agent at a place or places to be designated by the Administrative Agent or the Collateral Agent. If an Event of Default occurs and is continuing, the Administrative Agent or the Collateral Agent shall have the right to obtain access to any Borrower’s data processing equipment, computer hardware and software relating to the Collateral and to use all of the foregoing and the information contained therein in any manner the Administrative Agent or the Collateral Agent deems appropriate.

SECTION 9.06. Sale or Other Disposition of Collateral by the Administrative Agent or the Collateral Agent. Any notice required to be given by the Administrative Agent or the Collateral Agent of a sale, lease or other disposition or other intended action by the Administrative Agent or the Collateral Agent with respect to any of the Collateral which is deposited in the United States mails, registered or certified, postage prepaid and duly addressed to the Borrowers at the address specified in Section 11.01 below, at least ten days prior to such proposed action shall constitute fair and reasonable notice to the Borrowers of any such action. The net proceeds realized by the Administrative Agent or the Collateral Agent upon any such sale or other disposition, after deduction for the expense of retaking, holding, preparing for sale, selling or the like and the reasonable attorneys’ fees and legal expenses incurred by the Administrative Agent or the Collateral Agent in connection therewith, shall be applied as provided herein toward satisfaction of the Obligations. The Administrative Agent or the Collateral Agent, as applicable, shall account for and pay to the Borrowers any surplus realized upon such sale or other disposition, and the Borrowers shall remain liable for any deficiency. The commencement of any action, legal or equitable, or the rendering of any judgment or decree for any deficiency shall not affect the Administrative Agent’s or the Collateral Agent’s security interest in the Collateral. The Borrowers agree that the Collateral Agent has no obligation to preserve rights to the Collateral against any other parties. The Administrative Agent and the Collateral Agent are hereby granted a license or other right to use, without charge, the Borrowers’ labels, patents, copyrights, rights of use of any name, trade secrets, trade names, trademarks, service marks and advertising matter, or any property of a similar nature, as it pertains to the Collateral, and the Borrowers’ rights under all licenses and all franchise agreements shall inure to the Administrative Agent’s and the Collateral Agent’s benefit until the Obligations are paid in full.

SECTION 9.07. Governmental Approvals. In connection with the enforcement by the Administrative Agent or the Collateral Agent of any remedies available to it as a result of any Event of Default, each Borrower agrees that it shall join and cooperate fully with, at the request of the Administrative Agent or the Collateral Agent, any receiver referred to below and/or the successful bidder or bidders at any foreclosure sale in a filing of an application (and furnishing any additional information that may be required in connection with such application or which the Administrative Agent or the Collateral Agent may believe relevant to such application) with the FCC, any PUC and all other applicable Governmental Authorities,

requesting their prior approval of (i) the operation or abandonment of all or the portion of any System and/or (ii) the transfer of control of such Borrower or assignment of all licenses, certificates, Governmental Approvals, approvals and permits, issued to such Borrower by the FCC, any PUC or any such Governmental Authorities with respect to any System and the operation thereof, to the Administrative Agent or the Collateral Agent, the receiver or to the successful bidder or bidders. In connection with the foregoing, each Borrower shall take such further actions, and execute all such instruments, as the Administrative Agent or the Collateral Agent reasonably deems necessary or desirable. Each Borrower agrees that the Administrative Agent or the Collateral Agent may enforce any obligation of such Borrower as set forth in this section by an action for specific performance. In addition, each Borrower hereby irrevocably constitutes and appoints the Administrative Agent and the Collateral Agent and any agent or officer thereof (which appointment is coupled with an interest) as its true and lawful attorney-in-fact with full irrevocable power and authority and in the place and stead of such Borrower and in the name of such Borrower or in its own name, from time to time in its discretion after the occurrence and during the continuance of an Event of Default and in connection with the foregoing, for the purpose of executing on behalf and in the name of such Borrower any and all of the above-referenced instruments and to take any and all appropriate action in furtherance of the foregoing. The exercise of any rights or remedies hereunder or under any other Loan Document by any Lender, the Administrative Agent or the Collateral Agent that may require FCC, any PUC or any other Governmental Authority approval shall be subject to obtaining such approval. Pending the receipt of any FCC, any PUC or any other Governmental Authority approval, no Borrower shall do anything to delay, hinder, interfere or obstruct the exercise of the Administrative Agent’s or the Collateral Agent’s rights or remedies hereunder in obtaining such approvals.

SECTION 9.08. Appointment of Receiver or Trustee. In connection with the exercise of its remedies under this Agreement, the Administrative Agent or the Collateral Agent may, upon the occurrence of an Event of Default, obtain the appointment of a receiver or trustee to assume, upon receipt of all necessary judicial, FCC, any PUC or other Governmental Authority consents or approvals, control of or ownership of any of the Governmental Approvals. Such receiver or trustee shall have all rights and powers provided to it by law or by court order or provided to the Administrative Agent or the Collateral Agent under this Agreement. Upon the appointment of such trustee or receiver, the Borrowers agree to cooperate, to the extent necessary or appropriate, in the expeditious preparation, execution and filing of an application to the FCC, any PUC or any other Governmental Authority or for consent to the transfer of control or assignment of any Borrower’s Governmental Approvals to the receiver or trustee.

SECTION 9.09. Right of Setoff. In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, upon the occurrence and during the continuance of any Event of Default, each Lender and each holder of any Note is hereby authorized at any time or from time to time, without notice to any Borrower or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and to apply any and all balances held by it at any of its offices for the account of any Borrower (regardless of whether such balances are then due to such Borrower) and any other properties or assets any time held or owing by that Lender or that holder to or for the credit or for the account of any Borrower against and on account of any of the Obligations which are not paid when due. Any Lender or holder of any Note exercising a right to set off or otherwise receiving

any payment on account of the Obligations in excess of its Pro Rata Share thereof shall purchase for cash (and the other Lenders or holders shall sell) such participation in each such other Lender’s or holder’s Pro Rata Share of the Obligations as would be necessary to cause such Lender to share the amount so set off or otherwise received with each other Lender or holder in accordance with their respective Pro Rata Shares. Each Borrower agrees, to the fullest extent permitted by law, that (a) any Lender or holder may exercise its right to set off with respect to amounts in excess of its Pro Rata Share of the Obligations and may sell participations in such amount so set off to other Lenders and holders and (b) any Lender or holder so purchasing a participation in the Loans made or other Obligations held by other Lenders or holders may exercise all rights of set-off, bankers’ lien, counterclaim or similar rights with respect to such participation as fully as if such Lender or holder were a direct holder of the Loans and the other Obligations in the amount of such participation. Notwithstanding the foregoing, if all or any portion of the set-off amount or payment otherwise received is thereafter recovered from the Lender that has exercised the right of set-off, the purchase of participations by that Lender shall be rescinded and the purchase price restored without interest. Each Borrower hereby agrees that the foregoing provisions are intended to be construed so as to satisfy the requirements of Section 553 of the Federal Bankruptcy Code or amendments thereto (including any requirement of mutuality of obligations therein).

(a) CIBC is hereby appointed to act as contractual representative on behalf of all Lenders under this Agreement and the other Loan Documents. The Administrative Agent agrees to act as such contractual representative upon the express conditions contained in this Article X. The provisions of this Section 10.01 are solely for the benefit of the Administrative Agent and the Lenders and no Borrower or any other Person shall have any rights as a third party beneficiary of any of the provisions hereof. In performing its functions and duties under this Agreement and the other Loan Documents, the Administrative Agent shall act solely as an agent of the Lenders and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for any Borrower or any other Person. The Administrative Agent shall have no duties or responsibilities except for those expressly set forth in this Agreement and the other Loan Documents. Notwithstanding the use of the defined term “Administrative Agent”, it is expressly understood and agreed that the Administrative Agent shall not have any fiduciary responsibilities to any Lender by reason of this Agreement and that the Administrative Agent is merely acting as the representative of the Lenders with only those duties as are expressly set forth in this Agreement and the other Loan Documents. In its capacity as the Lenders’ contractual representative, the Administrative Agent (i) does not assume any fiduciary duties to any of the Lenders, (ii) is a “representative” of the Lenders within the meaning of Section 9-102(72) of the UCC and (iii) is acting as an independent contractor, the rights and duties of which are limited to those expressly set forth in this Agreement and the other Loan Documents.

(b) If the Administrative Agent shall request instructions from all Lenders, Requisite Lenders or all affected Lenders with respect to any act or action (including failure to act) in connection with this Agreement or any other Loan Document, then the Administrative Agent shall be entitled to refrain from such act or taking such action unless and until the Administrative Agent shall have received instructions from all Lenders, Requisite Lenders or all affected Lenders, as the case may be, and the Administrative Agent shall not incur liability to any Person by reason of so refraining. The Administrative Agent shall be fully justified in failing or refusing to take any action hereunder or under any other Loan Document (a) if such action would, in the opinion of the Administrative Agent, be contrary to law or the terms of this Agreement or any other Loan Document, (b) if such action would, in the reasonable opinion of the Administrative Agent, expose the Administrative Agent to liabilities beyond the limits of this Agreement or (c) if the Administrative Agent shall not first be indemnified to its satisfaction against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Without limiting the foregoing, no Lender shall have any right of action whatsoever against the Administrative Agent as a result of the Administrative Agent acting or refraining from acting hereunder or under any other Loan Document in accordance with the instructions of all Lenders, Requisite Lenders or all affected Lenders, as applicable.

SECTION 10.02. Administrative Agent’s Reliance, Etc. Neither the Administrative Agent nor any of its Affiliates nor any of their respective directors, officers, agents or employees shall be liable to any Lender for any action taken or omitted to be taken by it or them under or in connection with this Agreement or the other Loan Documents, except for damages caused by its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, the Administrative Agent: (a) may treat the payee of any Note as the holder thereof until the Administrative Agent receives written notice of the assignment or transfer thereof signed by such payee and in form satisfactory to the Administrative Agent; (b) may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations made in or in connection with this Agreement or the other Loan Documents; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement or the other Loan Documents on the part of any Borrower or to inspect the Collateral (including the books and records); (e) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or the other Loan Documents or any other instrument or document furnished pursuant hereto or thereto; and (f) shall incur no liability under or in respect of this Agreement or the other Loan Documents by acting upon any notice, consent, certificate or other instrument or writing (which may be by telecopy, telegram, cable or telex) reasonably believed by it to be genuine and signed or sent by the proper party or parties.

SECTION 10.03. CIBC and Affiliates. With respect to its Commitments hereunder, CIBC shall have the same rights and powers under this Agreement and the other Loan Documents 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, include CIBC in its individual capacity. CIBC and its Affiliates may lend money to, invest in, and generally engage in any kind of business with, any Borrower, any of its Affiliates and any Person who may do business with or own securities of any Borrower or any such Affiliate, all as if CIBC were not the Administrative Agent and without any duty to account therefor to Lenders. CIBC and its Affiliates may accept fees and other consideration from any Borrower for services in connection with this Agreement or otherwise without having to account for the same to Lenders. CIBC may also purchase or hold Equity Interests or warrants in the Guarantor or any Borrower and make subordinated loans to any Borrower. Each Lender acknowledges the potential conflict of interest between CIBC as a Lender holding disproportionate interests in the Loans, CIBC as a shareholder of the Guarantor, and CIBC, as Administrative Agent.

SECTION 10.04. Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on the financial information given it by the Borrowers and such other documents and information as it has deemed appropriate, made its own credit and financial analysis of the Borrowers and its own decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement. Each Lender acknowledges the potential conflict of interest of each other Lender as a result of Lenders holding disproportionate interests in the Loans, and expressly consents to, and waives any claim based upon, such conflict of interest.

SECTION 10.05. Indemnification. Each of the Lenders agrees to indemnify the Administrative Agent (to the extent not reimbursed by the Borrowers and without limiting the obligations of Borrowers hereunder), ratably according to their respective Pro Rata Shares, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of this Agreement or any other Loan Document or any action taken or omitted by the Administrative Agent in connection therewith; provided, however, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s gross negligence or willful misconduct. Without limiting the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement and each other Loan Document, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrowers.

SECTION 10.06. Successor Agent. The Administrative Agent may resign at any time by giving not less than thirty (30) days’ prior written notice thereof to Lenders and the Borrowers. Upon any such resignation, the Requisite Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Requisite Lenders and shall have accepted such appointment within 30 days

after the resigning Administrative Agent’s giving notice of resignation, then the resigning Administrative Agent may, on behalf of Lenders, appoint a successor Administrative Agent, which shall be a Lender, if a Lender is willing to accept such appointment, or otherwise shall be a commercial bank or financial institution or a subsidiary of a commercial bank or financial institution if such commercial bank or financial institution is organized under the laws of the United States of America or of any State thereof and has a combined capital and surplus of at least $300,000,000. If no successor Administrative Agent has been appointed pursuant to the foregoing, by the thirtieth day after the date such notice of resignation was given by the resigning Administrative Agent, such resignation shall become effective and the Requisite Lenders shall thereafter perform all the duties of Administrative Agent hereunder until such time, if any, as the Requisite Lenders appoint a successor Administrative Agent as provided above. Any successor Administrative Agent appointed by the Requisite Lenders hereunder shall be subject to the approval of Borrowers, such approval not to be unreasonably withheld or delayed; provided that such approval shall not be required if a Default or an Event of Default shall have occurred and be continuing. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall succeed to and become vested with all the rights, powers, privileges and duties of the resigning Administrative Agent. Upon the earlier of the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent or the effective date of the resigning Administrative Agent’s resignation, the resigning Administrative Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents, except that any indemnity rights or other rights in favor of such resigning Administrative Agent shall continue. After any resigning Administrative Agent’s resignation hereunder, the provisions of this Section 10.06 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents.

(a) Loans; Payments. Whenever the Administrative Agent receives a payment of principal, interest, fee or premium (if any) or other payment, or whenever the Administrative Agent makes an application of funds, in connection with the Loans or the Notes (including, without limitation, any payment or application from any Collateral), the Administrative Agent will on the date such payment is received or applied, if on or prior to 12:00 p.m. (Eastern time) on such date, or otherwise on the next Business Day, pay over to each Lender as instructed by such Lender in writing, an amount equal to such Lender’s Pro Rata Share of such payment provided that such Lender has funded all Loans required to be made by it and has purchased all participation required to be purchased by it under this Agreement and the other Loan Documents as of such date. To the extent that any Lender (a “Non-Funding Lender”) has failed to fund all such payments and Loans or failed to fund the purchase of all such participation, the Administrative Agent shall be entitled to set off the funding short-fall against that Non-Funding Lender’s Pro Rata Share of all payments received from the Borrowers. All payments by Administrative Agent shall be made by wire transfer to such Lender’s account (as specified by such Lender) not later than 3:00 p.m. (Eastern time) on the applicable Business Day.

(1) If the Administrative Agent pays an amount to a Lender under this Agreement in the belief or expectation that a related payment has been or will be received by the Administrative Agent from the Borrowers and such related payment is not received by Administrative Agent, then the Administrative Agent will be entitled to recover such amount from such Lender on demand without set-off, counterclaim or deduction of any kind.

(2) If the Administrative Agent determines at any time that any amount received by the Administrative Agent under this Agreement must be returned to any Borrower or paid to any other Person pursuant to any insolvency law or otherwise, then, notwithstanding any other term or condition of this Agreement or any other Loan Document, the Administrative Agent will not be required to distribute any portion thereof to any Lender. In addition, each Lender will repay to the Administrative Agent on demand any portion of such amount that the Administrative Agent has distributed to such Lender, together with interest at such rate, if any, as the Administrative Agent is required to pay to any Borrower or such other Person, without set-off, counterclaim or deduction of any kind.

(c) Non-Funding Lenders. The failure of any Non-Funding Lender to make any portion of its Loans or any payment required by it hereunder on the date specified therefor shall not relieve any other Lender (each such other Lender, an “Other Lender”) of its obligations to make any such Loan on such date, but neither any Other Lender nor the Administrative Agent shall be responsible for the failure of any Non-Funding Lender to make any Loan. Notwithstanding anything set forth herein to the contrary, a Non-Funding Lender shall not have any voting or consent rights under or with respect to any Loan Document or constitute a “Lender” (or be included in the calculation of “Requisite Lenders” hereunder) for any voting or consent rights under or with respect to any Loan Document.

(d) Dissemination of Information. The Administrative Agent will use reasonable efforts to provide Lenders with any notice of Default or Event of Default received by the Administrative Agent from, or delivered by the Administrative Agent to, the Borrowers, with notice of any Event of Default of which the Administrative Agent has actually become aware and with notice of any action taken by the Administrative Agent following any Event of Default; provided, however, that the Administrative Agent shall not be liable to any Lender for any failure to do so, except to the extent that such failure is attributable to the Administrative Agent’s gross negligence or willful misconduct. Lenders acknowledge that the Borrowers are required to provide financial statements and other documents to Lenders pursuant to this Agreement and agree that the Administrative Agent shall have no duty to provide the same to Lenders.

(e) Actions in Concert. Anything in this Agreement to the contrary notwithstanding, each Lender hereby agrees with each other Lender that no Lender shall take any action to protect or enforce its rights arising out of this Agreement or the Notes (including exercising any rights of set-off) without first obtaining the prior written consent of the Administrative Agent and Requisite Lenders, it being the intent of Lenders that any such action to protect or enforce rights under this Agreement and the Notes shall be taken in concert and at the direction or with the consent of Administrative Agent.

(a) The Lenders hereby irrevocably authorize the Collateral Agent, at its option and in its reasonable business judgment, to release any Lien upon any Collateral (i) upon the termination of the Commitments and payment and satisfaction of all Loans and all other Obligations and which the Collateral Agent has been notified in writing are then due and payable; (ii) constituting property being sold or disposed of if the applicable Borrower certifies to the Collateral Agent that the sale or disposition is made in compliance with Section 6.03 (and the Collateral Agent may rely conclusively on any such certificate, without further inquiry); or (iii) constituting property leased to the applicable Borrower under a lease which has expired or been terminated in a transaction permitted under this Agreement or which will expire imminently and which has not been, and is not intended by such Borrower to be, renewed or extended and with respect to which such Borrower has not exercised any purchase option. Except as provided above, the Collateral Agent will not release or subordinate any of the Liens without the prior written authorization of the Requisite Lenders; provided that the Collateral Agent may not release or subordinate the Liens on Collateral valued in the aggregate in excess of $500,000 without the prior written authorization of the Requisite Lenders and may not release all or substantially all of the Collateral or subordinate the Liens thereon without the consent of the Lenders. Upon request by the Collateral Agent or the Borrowers at any time, the Lenders will confirm in writing the Collateral Agent’s authority to release any Liens upon particular types or items of Collateral pursuant to this Section 10.08(a).

(b) Upon receipt by the Collateral Agent of any authorization required pursuant to Section 10.08(a) from the Requisite Lenders or Lenders, as applicable, of the Collateral Agent’s authority to release any Liens upon particular types or items of Collateral, and upon at least five (5) Business Days’ prior written request by the applicable Borrower, and provided that no Event of Default has occurred and is then continuing, the Collateral Agent shall (and is hereby irrevocably authorized by the Lenders to) execute such documents as may be necessary to evidence the release of the Liens upon such Collateral; provided, however, that (i) the Collateral Agent shall not be required to execute any such document on terms which, in the Collateral Agent’s opinion, would expose the Collateral Agent to liability or create any obligation or entail any consequence other than the release of such Liens without recourse or warranty, and (ii) such release shall not in any manner discharge, affect or impair the Obligations or any Liens (other than those expressly being released) upon (or obligations of the applicable Borrower in respect of) all interests retained by the applicable Borrower, including (without limitation) the proceeds of any sale, all of which shall continue to constitute part of the Collateral.

(c) The Collateral Agent shall have no obligation whatsoever to any of the Lenders to assure that the Collateral exists or is owned by any Borrower or is cared for, protected or insured or has been encumbered, or, other than a duty to act without recklessness, willful misconduct or gross (but not mere) negligence, that the Liens have been properly or sufficiently or lawfully created, perfected, protected or enforced or are entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure or fidelity, or to continue exercising, any of the rights, authorities and powers granted or available to the pursuant to this Section 10.08 or pursuant to any of the Loan Documents, it being understood and agreed that in respect of the Collateral, or any act, omission or event related thereto, the Collateral Agent may act in any manner it may deem appropriate, in its reasonable business judgment, given the Collateral Agent’s own interest in the Collateral in its capacity as one of the

Lenders and that the Collateral Agent shall have no other duty or liability whatsoever to any Lender as to any of the foregoing.

SECTION 10.09. Agency for Perfection. Each Lender hereby appoints each other Lender as agent for the purpose of perfecting the Lenders’ security interest in assets which, in accordance with Article 9 of the UCC can be perfected only by possession. Should any Lender (other than the Collateral Agent) obtain possession of any such Collateral, such Lender shall notify the Collateral Agent thereof, and, promptly upon the Collateral Agent’s request therefor shall deliver such Collateral to the Collateral Agent.

SECTION 10.10. Concerning the Collateral and the Related Loan Documents and the Collateral Agent.

(a) Each Lender authorizes and directs the Collateral Agent to enter into this Agreement and the other Loan Documents relating to the Collateral and the Guaranty, for the ratable benefit of the Lenders. Each Lender agrees that any action taken by the Collateral Agent or Requisite Lenders in accordance with the terms of this Agreement or the other Loan Documents relating to the Collateral and the Guaranty, and the exercise by the Collateral Agent or the Requisite Lenders of their respective powers set forth therein or herein, together with such other powers that are reasonably incidental thereto, shall be binding upon all of the Lenders.

(b) The Collateral Agent with respect to the administration of the Collateral and the Guaranty shall have the same rights, obligations and status as the Administrative Agent as are set forth in Section 10.01, 10.02, 10.03, 10.04, 10.05, and 10.06 above.

SECTION 10.11. Resignation of CIBC as Administrative Agent. Effective as of May 1, 2004 (the “Agent Transfer Date”) CIBC shall no longer have any rights or duties as Administrative Agent under this Agreement and on a going forward basis, all of such rights shall as of such date be automatically assigned to, and all of such duties shall automatically be assumed by, General Electric Capital Corporation in its capacity as Administrative Agent under this Agreement. Without limiting the foregoing, all grants of security interests and rights of setoff against any Borrower’s or the Guarantor’s respective properties under the Loan Documents executed prior to the Agent Transfer Date in favor of CIBC as Administrative Agent, if any, shall on and after the Closing Date be deemed to be grants in favor of General Electric Capital Corporation in its capacity as Administrative Agent under this Agreement.

(a) Notices and other communications provided for herein shall be in writing and shall be delivered by a courier service of recognized standing (specifying one (1) day delivery), or by registered or certified mail, postage prepaid, return receipt requested (or, if by telecopy communications equipment of the sending party, delivered by such equipment) addressed to the addresses set forth below:

(b) All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given (i) five Business Days after mailing when sent by registered or certified mail, postage prepaid, return receipt requested, or (ii) upon receipt, if by courier service or any telecopy communications equipment of the sender, in each case addressed to such party as provided in this Section or in accordance with the latest unrevoked direction from such party.

(c) Each Borrower agrees that the Administrative Agent and the Collateral Agent may act upon any notice, consent, certificate, cable, telex or other instrument or writing believed by the Administrative Agent or the Collateral Agent to be genuine, that the Administrative Agent or the Collateral Agent may consult with legal counsel, selected by the Administrative Agent or the Collateral Agent and shall not be liable to any Borrower for any action taken or omitted to be taken in good faith by Lender in accordance with the advice of such counsel.

(a) No failure or delay of the Administrative Agent, the Collateral Agent or any Lender to exercise any right hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, preclude any other or further exercise thereof or the exercise of any other right. No waiver of any provision of this Agreement or any other Loan Document (exclusive of any Interest Rate Agreement) nor consent to any departure by any Borrower therefrom shall in any event be effective unless the same shall be in writing and signed by the Administrative Agent and the Requisite Lenders, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on any Borrower in any case shall entitle any Borrower to any other or further notice or demand in similar or other circumstances.

(b) Subject to the provisions of this Section 11.02(b), the Requisite Lenders (or the Administrative Agent with the consent in writing of the Requisite Lenders) and the Borrowers may enter into agreements supplemental hereto for the purpose of adding or modifying any provisions to the Loan Documents or changing in any manner the rights of the Lenders or the Borrowers hereunder or waiving any Event of Default or Default hereunder; provided, that any Interest Rate Agreement which constitutes a Loan Document may be amended or modified solely with the consent of the parties thereto; provided, further, however, that no such supplemental agreement shall, without the consent of each Lender affected thereby:

(1) Postpone or extend the Revolving Loan Commitment Termination Date, the Term Loan Termination Date, the maturity date for the Loans or any other date fixed for any payment of principal of, or interest on, the Loans or any fees or other amounts payable to such Lender except with respect to (A) any modifications of the provisions

relating to prepayments of Loans and other Obligations and (B) a waiver of the application of the default rate of interest pursuant to Section 2.05(b) hereof.

(2) Reduce the principal amount of any Loans, or reduce the rate or extend the time of payment of interest or fees thereon.

(3) Reduce the percentage specified in the definition of Requisite Lenders or any other percentage of Lenders specified to be the applicable percentage in this Agreement to act on specified matters or amend the definition of “Pro Rata Share”.

(4) Increase the amount of any Commitment of any Lender hereunder or increase any Lender’s Pro Rata Share.

No amendment of any provision of this Agreement relating to the Administrative Agent or the Collateral Agent shall be effective without the written consent of the Administrative Agent or the Collateral Agent, as applicable.

SECTION 11.03. GOVERNING LAW AND JURISDICTION. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO ANY CONFLICTS OF LAWS PRINCIPLES. THE BORROWERS, THE ADMINISTRATIVE AGENT, THE COLLATERAL AGENT AND THE LENDERS CONSENT TO THE JURISDICTION OF ANY LOCAL, STATE OR FEDERAL COURT LOCATED IN THE STATE OF NEW YORK AND WAIVE ANY OBJECTION RELATING TO IMPROPER VENUE OR FORUM NON CONVENIENS TO THE CONDUCT OF ANY PROCEEDING BY SUCH COURT.

SECTION 11.04. Expenses; Documentary Taxes. The Borrowers will pay, and have joint and several liability for, all documented out-of-pocket third-party expenses (i) incurred by the Administrative Agent and the Collateral Agent in connection with the negotiation, preparation and execution of the Loan Documents (whether or not the transactions contemplated hereby shall be consummated), and (ii) by the Administrative Agent, the Collateral Agent or the Lenders in connection with the administration of the Loan Documents, the creation, perfection, priority and protection of the Liens in the Collateral, and the enforcement of the rights of the Administrative Agent, the Collateral Agent or the Lenders in connection with this Agreement, any other Loan Documents or the Collateral, including all reasonable attorneys’ and paralegals’ fees and related expenses and costs. The Borrowers agree that they shall jointly and severally indemnify the Administrative Agent, the Collateral Agent and the Lenders from and hold them harmless against any documentary taxes, assessments or charges made by any Governmental Authority by reason of the execution and delivery of this Agreement or any other Loan Document unless prohibited by law.

SECTION 11.05. Equitable Relief. Each Borrower recognizes that, in the event such Borrower fails to perform, observe or discharge any of its obligations or liabilities under

this Agreement, or any other Loan Document, any remedy at law may prove to be inadequate relief to the Administrative Agent, the Collateral Agent and the Lenders; therefore, such Borrower agrees that the Administrative Agent or the Collateral Agent, if it so requests, shall be entitled to temporary and permanent injunctive relief in any such case without the necessity of proving actual damages.

(a) The Borrowers jointly and severally agree to protect, indemnify and hold harmless the Administrative Agent, the Collateral Agent, each Lender and each of their respective officers, affiliates, directors, employees, attorneys, accountants, consultants, representatives and agents (collectively called the “Indemnitees”) from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, expenses and disbursements (including, without limitation, payment by the Administrative Agent, the Collateral Agent or any Lender of any obligations due or past due under any contract or agreement to which any Borrower is or becomes a party) of any kind or nature whatsoever (including, without limitation, the fees and disbursements of counsel for and consultants of such Indemnitees in connection with any investigative, administrative or judicial proceeding, whether or not such Indemnitees shall be designated a party thereto), which may be imposed on, incurred by, or asserted against such Indemnitees (whether direct, indirect, or consequential and whether based on any federal or state laws or other statutory regulations, including, without limitation, securities, environmental and commercial laws and regulations, under common law or at equitable cause or on contract or otherwise) in any manner relating to or arising out of this Agreement or any of the other Loan Documents (other than claims arising solely from a dispute between the Administrative Agent, the Collateral Agent and any number of Lenders or between any two or more Lenders), or any act, event or transaction related or attendant thereto, the agreements of the Administrative Agent, the Collateral Agent or the Lenders contained herein, the making of Loans or the issuance of Letters of Credit, the management of such Loans, Letters of Credit or the Collateral (including any liability under federal, state or local environmental laws or regulations) or the use or intended use of the proceeds of such Loans hereunder or of such Letters of Credit hereunder (collectively, the “Indemnified Matters”); provided that the Borrowers shall not have any obligation to any Indemnitee hereunder with respect to Indemnified Matters caused by or resulting from the willful misconduct or gross negligence of such Indemnitee; provided, further that no Borrower shall have any obligation to any Indemnitee hereunder with respect to taxes that are imposed on the net income of any Indemnitee or any franchise or doing business taxes imposed on any Indemnitee. To the extent that the undertaking to indemnify, pay and hold harmless set forth in the preceding sentence may be unenforceable because it is violative of any law or public policy, the Borrowers shall contribute the maximum portion which they are permitted to pay and satisfy under applicable law, to the payment and satisfaction of all Indemnified Matters incurred by the Indemnitees.

(b) To the extent permitted by applicable law, no claim may be made by the Borrowers or any other Person against the Administrative Agent, the Collateral Agent, any Lender or any of their respective affiliates, directors, officers, employees, agents, attorneys, accountants, representatives or consultants for any special, indirect, consequential or punitive damages in respect of any claim for breach of contract or any other theory of liability arising out of or related to the transactions contemplated by any of the Loan Documents or any act, omission

or event occurring in connection therewith; and the Borrowers hereby waive, release and agree not to sue upon any claim for any such damages, whether or not accrued and whether or not known or suspected to exist in its favor.

SECTION 11.07. Survival of Representations and Warranties, etc. All warranties and representations made by any Borrower in any Loan Document shall survive the execution and delivery of this Agreement and the other Loan Documents and the making and repayment of the Obligations. The confidentiality obligations of each Borrower in Section 11.16, the indemnification obligations of each Borrower in Section 11.06, and to the extent the second sentence of Section 11.13 is applicable, all covenants of each Borrower, survive the repayment of the Obligations.

(a) General. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Borrowers, the Administrative Agent, the Collateral Agent and the Lenders and their respective successors and assigns, except that (i) no Borrower shall have any right to assign its rights or obligations under the Loan Documents and (ii) any assignment by any Lender must be made in compliance with subsection (c) below. Notwithstanding the foregoing, any Lender may at any time, without the consent of the Borrowers or the Administrative Agent, assign all or any portion of its rights under this Agreement and its Notes to a Federal Reserve Bank or to an affiliate of such Lender; provided, however, that no such assignment shall release the transferor Lender from its obligations hereunder. The Administrative Agent shall be entitled to utilize its Register to determine the payee of any Note for all purposes hereof. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the holder of any Note, shall be conclusive and binding on any subsequent holder, transferee or assignee of such Note or of any Note or Notes issued in exchange therefor.

(1) Subject to the terms set forth in this Section 11.08(b), any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time sell to one or more banks or other entities (“Participants”) participating interests in any Loan owing to such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender under the Loan Documents on a pro rata or non-pro rata basis in an aggregate principal amount of at least $1,000,000. In the event of any such sale by a Lender of participating interests to a Participant, such Lender’s obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the holder of any such Note for all purposes under the Loan Documents, such Lender shall be solely responsible for any withholding taxes or any filing or reporting requirements in connection therewith relating to such Participant, all amounts payable by the Borrowers under this Agreement shall be determined as if such Lender had not sold such participating interests, and the Borrowers and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under the Loan Documents except that, for purposes of Sections 2.12(b), 2.13 and 2.14 hereof, the Participants shall be

entitled to the same rights as if they were Lenders, provided that no Participant shall be entitled to receive any greater amount pursuant to Section s 2.12(b), 2.13 and 2.14 than such Lender would have been entitled to receive in respect of the amount of the participation transferred to such Participant had no transfer occurred.

(2) Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification or waiver with respect to any Loan or Commitment in which such Participant has an interest which forgives principal, interest or fees or reduces the interest rate or fees payable pursuant to the terms of this Agreement with respect to any such Loan or Commitment, postpones any date fixed for any regularly-scheduled payment of principal of, or interest or fees on, any such Loan or Commitment, or releases all or substantially all of the Collateral, if any, securing any such Loan.

(3) The Borrowers agree that each Participant shall be deemed to have the right of setoff provided in Section 9.09 hereof in respect to its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents, provided that each Lender shall retain the right of setoff provided in Section 9.09 hereof with respect to the amount of participating interests sold to each Participant except to the extent such Participant exercises its right of setoff. The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 9.09 hereof, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 9.09 as if each Participant were a Lender.

(1) Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time assign to one or more Permitted Assignees or Approved Funds (“Purchasers”) all or a portion of its rights and obligations under this Agreement (including, without limitation, its Commitment and the Loans owing to it hereunder) in accordance with the provisions of this Section 11.08(c). Each assignment shall be of a constant, and not a varying, ratable percentage of all of the assigning Lender’s rights and obligations under this Agreement. Such assignment shall be evidenced by an Assignment Agreement in form and substance reasonably satisfactory to the Administrative Agent and shall not be permitted hereunder unless such assignment (A) is either for all of such Lender’s rights and obligations under the Loan Documents or for Loans and Commitments in an aggregate principal amount equal to the lesser of $1,000,000 (which minimum amount may be waived by the Administrative Agent and the Borrower at any time that an Event of Default has not occurred and is not continuing and solely by the Administrative Agent upon the occurrence and during the continuance of an Event of Default) and such Lender’s Commitment Amount, and (B) is consented to by the Administrative Agent (such consent not to be unreasonably withheld) at any time that an Event of Default has not occurred and is not continuing.

(2) Upon (i) delivery to the Administrative Agent of a notice of assignment (a “Notice of Assignment”), together with any consent required hereunder, and (ii) payment

of a $3,500 processing fee to the Administrative Agent for processing such assignment (unless such assignment is made by one of the Agents to one of its affiliates, in which case no processing fee shall be assessed), such assignment shall become effective on the effective date specified in such Notice of Assignment. The assigning Lender shall be obligated to reimburse the Administrative Agent for all other costs and expenses associated with the preparation and execution of such assignment (including reasonable attorneys’ fees arising out of such preparation and execution of such assignment). The Notice of Assignment shall contain a representation by the Purchaser to the effect that none of the consideration used to make the purchase of the Commitment and Loans under the applicable assignment agreement are “plan assets” as defined under ERISA and that the rights and interests of the Purchaser in and under the Loan Documents will not be “plan assets” under ERISA. On and after the effective date of such assignment, such Purchaser, if not already a Lender, shall for all purposes be a Lender party to this Agreement and any other Loan Documents executed by the Lenders and shall have all the rights and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party hereto, and no further consent or action by the Borrowers, the Lenders or the Administrative Agent shall be required to release the transferor Lender with respect to the percentage of the aggregate Commitment and Loans assigned to such Purchaser. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 11.08(c)(2) shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 11.08(b). Upon the consummation of any assignment to a Purchaser pursuant to this Section 11.08(c)(2), the transferor Lender, the Administrative Agent and the Borrowers shall make appropriate arrangements so that replacement Notes are issued to such transferor Lender and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their Commitment and their Loans, as adjusted pursuant to such assignment.

(3) The Administrative Agent shall maintain at its address referred to in Section 11.01 a copy of each assignment delivered to and accepted by it pursuant to this Section 11.08 and a register (the “Register”) for the recordation of the names and addresses of the Lenders and the Commitment of and principal amount of the Loans owing to, each Lender from time to time and whether such Lender is an original Lender or the assignee of another Lender pursuant to an assignment under this Section 11.08. The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrowers, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrowers or any Lender at any reasonable time and from time to time upon reasonable prior notice.

SECTION 11.09. Severability. In case any one or more of the provisions contained in this Agreement or any other Loan Document shall be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby.

SECTION 11.10. Cover Page, Table of Contents and Section Headings. The cover page, Table of Contents and section headings used herein are for convenience of reference only, are not part of this Agreement and are not to affect the construction of or be taken into consideration in interpreting this Agreement.

SECTION 11.11. Counterparts. This Agreement may be signed in counterparts with the same effect as if the signatures thereof and hereto were upon the same instrument.

SECTION 11.12. Application of Payments. Notwithstanding any contrary provision contained in this Agreement or in any of the other Loan Documents, upon the occurrence and during the continuance of any Event of Default, each Borrower irrevocably waives the right to direct the application of any and all payments at any time or times hereafter received by the Administrative Agent or any Lender from such Borrower or with respect to any of the Collateral, and such Borrower does hereby irrevocably agree that the Administrative Agent or any Lender shall have the continuing exclusive right to apply and reapply any and all payments received at any time or times hereafter, whether with respect to the Collateral or otherwise, against the Obligations in such manner as the Administrative Agent or any Lender may deem advisable, notwithstanding any entry by the Administrative Agent or any Lender upon any of its books and records, subject, however, to the provisions of Section 2.08(c).

SECTION 11.13. Marshalling; Payments Set Aside. Neither the Administrative Agent nor the Collateral Agent shall be under any obligation to marshall any assets in favor of any Borrower or any other party or against or in payment of any or all of the Obligations. To the extent that any Borrower makes a payment or payments to the Administrative Agent, the Collateral Agent or any Lender or the Administrative Agent, the Collateral Agent or any Lender enforces its security interests or exercises its rights of setoff, and such payment or payments or the proceeds of such enforcement or setoff or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to a trustee, receiver or any other party under any bankruptcy law, state or federal law, common law or equitable cause, then 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 enforcement or setoff had not occurred.

SECTION 11.14. SERVICE OF PROCESS. EACH BORROWER WAIVES PERSONAL SERVICE OF ANY PROCESS UPON IT AND, CONSENTS THAT ALL SERVICE OF PROCESS SHALL BE MADE BY REGISTERED MAIL, RETURN RECEIPT REQUESTED, DIRECTED TO SUCH BORROWER AT THE ADDRESS INDICATED IN SECTION 11.01 AND SERVICE SO MADE SHALL BE DEEMED TO BE COMPLETED FIVE (5) BUSINESS DAYS AFTER SAME SHALL HAVE BEEN POSTED AS AFORESAID.

SECTION 11.15. WAIVER OF JURY TRIAL, ETC. EACH OF THE BORROWERS, THE ADMINISTRATIVE AGENT, THE COLLATERAL AGENT AND THE LENDERS WAIVES ANY RIGHT TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT, OR OTHERWISE, BETWEEN THE ADMINISTRATIVE AGENT, THE COLLATERAL AGENT OR ANY LENDER AND ANY BORROWER ARISING OUT OF, CONNECTED WITH, RELATED TO OR

INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION THEREWITH OR THE TRANSACTIONS RELATED THERETO. EACH OF THE BORROWERS, THE ADMINISTRATIVE AGENT, THE COLLATERAL AGENT AND THE LENDERS HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT ANY OF THEM MAY FILE AS AN ORIGINAL COUNTERPART OR A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

SECTION 11.16. Confidentiality. No Borrower shall at any time before or after payment in full and satisfaction of all of the Obligations, reveal, divulge or make known, or knowingly permit to be so revealed, divulged or made known, to any Person (including Persons within its own organization who do not have a definite need to know for the purpose of performance of this Agreement), the terms or conditions of this Agreement or any document or agreement now or hereafter executed in connection herewith except (i) the Borrowers may reveal such terms and conditions to their respective legal counsel and accountants who agree to keep such terms and conditions confidential, (ii) the Borrowers may disclose the aggregate amount and maturity of the credit facility evidenced by this Agreement and the identity of the Administrative Agent to its investors, (iii) with the prior consent of the Administrative Agent as to timing and content, the Borrowers may issue a press release relating to this Agreement and the facilities evidenced hereby, (iv) information required to be disclosed by order of a court of competent jurisdiction or in connection with any governmental investigation (in each case to the extent disclosure is required, but no further) may be disclosed so long as such Borrower notifies the Administrative Agent in writing of any circumstances of which such Borrower is aware that may lead to such a requirement or order, so as to allow the Administrative Agent to take steps to contest such order or investigation, (v) information which is required to be disclosed by such Borrower or information which in the reasonable determination of such Borrower is desirable for such Borrower to disclose (including, without limitation, in each case, this Agreement), pursuant to federal or state securities laws, pursuant to the rules or regulations of the FCC, any PUC or other applicable Governmental Authority may be so disclosed and (vi) information may be disclosed to Persons who may potentially provide debt financing (other than a lender providing secured financing to such Borrower or any debt financing in replacement of the Loans) or equity financing to such Borrower or any Affiliate with respect to its Business and any consultants or advisors of such Person, or to Persons who are consultants, advisors (including but not limited to attorneys and auditors), officers, directors or employees of such Borrower, provided that each such Person is required by such Borrower to keep such information confidential.

SECTION 11.17. Entire Agreement, etc. This Agreement (including all schedules and exhibits referred to herein), the Notes, the Fee Letters and all other Loan Documents constitute the entire contract between the parties hereto with respect to the subject matter hereof and thereof and shall supersede and take the place of any other instrument purporting to be an agreement of the parties hereto relating to such subject matter.

SECTION 11.18. No Strict Construction. The parties hereto have participated, jointly in the negotiation and drafting of this Agreement. In the event of any ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of authorship of any provisions of this Agreement.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their duly authorized officers as of the day and year first above written.
