     Section 2. AMOUNTS AND TERMS OF COMMITMENTS AND LOANS

          2.1 Commitments; Making of Loans; the Register; Notes

          A. Commitments. Subject to the terms and conditions of this Agreement and in reliance upon the representations and warranties of Company herein set forth, each Lender hereby severally agrees to make a Loan to Company on the Funding Date in an aggregate principal amount not to exceed its Commitment. Each Lender’s Commitment shall expire immediately and without further action upon the earliest to occur of (i) 5:00 P.M. (New York City time) on the Outside Date, (ii) the consummation of the Acquisition, (iii) the date that the Merger Agreement is terminated or expires or pursuit of the Acquisition is abandoned and (iv) the funding of the Loans on the Funding Date. Amounts borrowed under this subsection 2.1A and subsequently repaid or prepaid may not be reborrowed.

          B. Borrowing Mechanics. Whenever Company desires that Lenders make the Loans it shall deliver to Administrative Agent a Notice of Borrowing no later than 12:00 Noon (New York City time) at least three Eurodollar Business Days in advance of the Funding Date (in the case of a Eurodollar Rate Loan) or at least one Business Day in advance of the Funding Date (in the case of an Alternate Base Rate Loan). The Notice of Borrowing shall specify (i) the Funding Date (which shall be a Business Day), (ii) the amount of Loans requested, (iii) whether such Loans shall be Alternate Base Rate Loans or Eurodollar Rate Loans and (iv) in the case of any Loans requested to be made as Eurodollar Rate Loans, the initial Interest Period

requested therefor. Loans may be continued as or converted into Alternate Base Rate Loans and Eurodollar Rate Loans in the manner provided in subsection 2.2D. In lieu of delivering the above-described Notice of Borrowing, Company may give Administrative Agent telephonic notice by the required time of any proposed borrowing under this subsection 2.1B; provided that such notice shall be promptly confirmed in writing by delivery of a Notice of Borrowing to Administrative Agent on or before the Funding Date.

          Neither Administrative Agent nor any Lender shall incur any liability to Company in acting upon any telephonic notice referred to above that Administrative Agent believes in good faith to have been given by a duly authorized officer or other person authorized to borrow on behalf of Company or for otherwise acting in good faith under this subsection 2.1B, and upon funding of Loans by Lenders in accordance with this Agreement pursuant to any such telephonic notice Company shall have effected Loans hereunder.

          Company shall notify Administrative Agent prior to the funding of any Loans in the event that any of the matters to which Company is required to certify in the applicable Notice of Borrowing is no longer true and correct as of the Funding Date, and the acceptance by Company of the proceeds of any Loans shall constitute a re-certification by Company, as of the Funding Date, as to the matters to which Company is required to certify in the applicable Notice of Borrowing.

          Except as otherwise provided in subsections 2.6B, 2.6C and 2.6G, a Notice of Borrowing for a Eurodollar Rate Loan (or telephonic notice in lieu thereof) shall be irrevocable on and after the related Interest Rate Determination Date, and Company shall be bound to make a borrowing in accordance therewith.

          C. Disbursement of Funds. All Loans under this Agreement shall be made by Lenders simultaneously on the Funding Date and proportionately to their respective Pro Rata Shares, it being understood that no Lender shall be responsible for any default by any other Lender in that other Lender’s obligation to make a Loan requested hereunder nor shall the Commitment of any Lender to make the Loan requested be increased or decreased as a result of a default by any other Lender in that other Lender’s obligation to make a Loan requested hereunder. Promptly after receipt by Administrative Agent of a Notice of Borrowing pursuant to subsection 2.1B (or telephonic notice in lieu thereof), Administrative Agent shall notify each Lender of the proposed borrowing. Each Lender shall make the amount of its Loan available to Administrative Agent not later than 12:00 Noon (New York City time) on the Funding Date in same day funds in Dollars, at the Funding and Payment Office. Upon satisfaction or waiver of the conditions precedent specified in subsection 4.2, Administrative Agent shall make the proceeds of the Loans available to Company on the Funding Date by causing an amount of same day funds in Dollars equal to the proceeds of all such Loans received by Administrative Agent from Lenders to be credited to the account of Company.

          Unless Administrative Agent shall have been notified by any Lender prior to the Funding Date that such Lender does not intend to make available to Administrative Agent the amount of such Lender’s Loan requested on the Funding Date, Administrative Agent may assume that such Lender has made such amount available to Administrative Agent on the Funding Date and Administrative Agent may, in its sole discretion, but shall not be obligated to, make available to Company a corresponding amount on the Funding Date. If such corresponding amount is not in fact made available to Administrative Agent by such Lender, Administrative Agent shall be entitled to recover such corresponding amount on demand from such Lender together with interest thereon, for each day from the Funding Date until the date such amount is paid to Administrative Agent, at the customary rate set by Administrative Agent for the correction of errors among banks for three Business Days and thereafter at the Alternate Base Rate. If such Lender does not pay such corresponding amount within three Business Days after such amount should have been made available, Administrative Agent shall promptly notify Company and Company shall immediately pay such corresponding amount to Administrative Agent together with interest thereon, for each day from the Funding Date until the date such amount is paid to Administrative Agent, at the rate payable under this Agreement for Alternate Base Rate Loans. Nothing in this subsection 2.1C shall be deemed to relieve any Lender from its obligation to fulfill its Commitments hereunder or to prejudice any rights that Company may have against any Lender as a result of any default by such Lender hereunder.

          D. The Register.

               (i) Administrative Agent, acting solely for this purpose as a non-fiduciary agent of Company, shall maintain, at its address referred to in subsection 10.8, a register for the recordation of the names and addresses of Lenders and the Commitments and Loans of each Lender from time to time (the “Register”). The Register shall be available for inspection by Company or any Lender at any reasonable time and from time to time upon reasonable prior notice.

               (ii) Administrative Agent shall record in the Register the Commitment and the Loans from time to time of each Lender and each repayment or prepayment in respect of the principal amount of the Loans of each Lender. Any such recordation shall be conclusive and binding on Company and each Lender, absent manifest error; provided that failure to make any such recordation, or any error in such recordation, shall not affect any Lender’s Commitments or Company’s Obligations in respect of any applicable Loans.

               (iii) Each Lender shall record on its internal records (including any Notes held by such Lender) each Loan made by it and each payment in respect thereof. Any such recordation shall be conclusive and binding on Company, absent manifest error; provided that failure to make any such recordation, or any error in such recordation, shall not affect any Lender’s Commitments or Company’s Obligations in respect of any applicable Loans; and provided, further, that in the event of any

inconsistency between the Register and any Lender’s records, the recordations in the Register shall govern.

               (iv) Company, Administrative Agent and Lenders shall deem and treat the Persons listed as Lenders in the Register as the holders and owners of the corresponding Commitments and Loans listed therein for all purposes hereof, and no assignment or transfer of any such Commitment or Loan shall be effective, in each case unless and until an Assignment Agreement effecting the assignment or transfer thereof shall have been accepted by Administrative Agent and recorded in the Register as provided in subsection 10.1B(ii). Prior to such recordation, all amounts owed with respect to the applicable Commitment or Loan shall be owed to the Lender listed in the Register as the owner thereof, and any request, authority or consent of any Person who, at the time of making such request or giving such authority or consent, is listed in the Register as a Lender shall be conclusive and binding on any subsequent holder, assignee or transferee of the corresponding Commitments or Loans.

               (v) Company hereby designates Credit Suisse to serve as Company’s agent solely for purposes of maintaining the Register as provided in this subsection 2.1D, and Company hereby agrees that, to the extent Credit Suisse serves in such capacity, Credit Suisse and its officers, directors, employees, agents and affiliates shall constitute Indemnitees for all purposes under subsection 10.3.

          E. Notes. At the request of any Lender, Company shall execute and deliver to that Lender (or to Administrative Agent for that Lender) a Note substantially in the form of Exhibit IV annexed hereto to evidence that Lender’s Loan, in the principal amount of that Lender’s Loan and with other appropriate insertions. In the event a Lender requests such Note at least 3 Business Days prior to the Funding Date, Company shall execute and deliver such Note on such date.

          2.2 Interest on the Loans

          A. Rate of Interest. Subject to the provisions of subsections 2.6 and 2.7, the Loans shall bear interest on the unpaid principal amount thereof from the Funding Date through maturity (whether by acceleration or otherwise) at a rate determined by reference to the Alternate Base Rate or the Adjusted Eurodollar Rate. The applicable basis for determining the rate of interest with respect to any Loans shall be selected by Company initially at the time a Notice of Borrowing is given with respect to the Loans pursuant to subsection 2.1B, and the basis for determining the interest rate with respect to any Loans may be changed from time to time pursuant to subsection 2.2D. If on any day Loans are outstanding with respect to which notice has not been delivered to Administrative Agent in accordance with the terms of this Agreement specifying the applicable basis for determining the rate of interest, then for that day such Loans shall bear interest determined by reference to the Alternate Base Rate. Subject to the provisions of subsections 2.2E and 2.7, the Loans shall bear interest through maturity as follows:

               (i) if an Alternate Base Rate Loan, then at the sum of the Alternate Base Rate and the applicable Alternate Base Rate Margin set forth in the table below opposite the Consolidated Leverage Ratio for the four-Fiscal Quarter period ending on the date for which the applicable Compliance Certificate has been delivered pursuant to subsection 6.1(iii):

provided, that the Alternate Base Rate Margin will increase by 0.25% on the 90^th day after the Funding Date and by an additional 0.25% every 90 days thereafter.

               (ii) if a Eurodollar Rate Loan, then at the sum of the Adjusted Eurodollar Rate and the applicable Eurodollar Rate Margin set forth in the table below opposite the Consolidated Leverage Ratio for the four-Fiscal Quarter period ending on the date for which the applicable Compliance Certificate has been delivered pursuant to subsection 6.1(iii):

CONSOLIDATED LEVERAGE RATIO

          B. Interest Periods. In connection with each Eurodollar Rate Loan, Company may, pursuant to the applicable Notice of Borrowing or Notice of Conversion/Continuation, as the case may be, select an interest period (each an “Interest Period”) to be applicable to such Loan, which Interest Period shall be, at Company’s option, a one, two or three month period; provided that:

               (i) the initial Interest Period for any Eurodollar Rate Loan shall commence on the Funding Date in respect of such Loan, in the case of Loans being initially made as Eurodollar Rate Loans, or on the date specified in the applicable Notice of Conversion/Continuation, in the case of Loans being converted to Eurodollar Rate Loans;

               (ii) in the case of immediately successive Interest Periods applicable to a Eurodollar Rate Loan continued as such pursuant to a Notice of Conversion/Continuation, each successive Interest Period shall commence on the day on which the next preceding Interest Period expires;

               (iii) if an Interest Period would otherwise expire on a day that is not a Business Day, such Interest Period shall expire on the next succeeding Business Day; provided that, if any Interest Period would otherwise expire on a day that is not a Business Day but is a day of the month after which no further Business Day occurs in such month, such Interest Period shall expire on the next preceding Business Day;

               (iv) any Interest Period that begins on the last Business Day of a calendar month (or on a day for which there is no numerically corresponding day in the calendar month at the end of such Interest Period) shall, subject to clause (v) of this subsection 2.2B, end on the last Business Day of a calendar month;

               (v) no Interest Period with respect to any portion of the Loans shall extend beyond the Original Maturity Date; provided that to the extent that the maturity of any portion of the Loans is extended to the Extended Maturity Date in accordance with subsection 2.4A(ii), then Interest Periods with respect to the portion of the Loans so extended may extend beyond the Original Maturity Date (but not beyond the Extended Maturity Date);

               (vi) there shall be no more than four Interest Periods outstanding at any time; and

Conversion/Continuation, Company shall be deemed to have selected an Interest Period of one month.

          C. Interest Payments.

          D. Conversion or Continuation. Subject to the provisions of subsection 2.6, Company shall have the option (i) to convert at any time all or any part of its outstanding Loans equal to $5,000,000 and integral multiples of $1,000,000 in excess of that amount from Loans bearing interest at a rate determined by reference to one basis to Loans bearing interest at a rate determined by reference to an alternative basis or (ii) upon the expiration of any Interest Period applicable to a Eurodollar Rate Loan, to continue all or any portion of such Loan equal to $5,000,000 and integral multiples of $1,000,000 in excess of that amount as a Eurodollar Rate Loan; provided, however, that a Eurodollar Rate Loan may only be converted into a Alternate Base Rate Loan on the expiration date of an Interest Period applicable thereto.

          Company shall deliver a Notice of Conversion/Continuation to Administrative Agent no later than 12:00 Noon (New York City time) at least one Business Day in advance of the proposed conversion date (in the case of a conversion to an Alternate Base Rate Loan) and at least three Eurodollar Business Days in advance of the proposed conversion/continuation date (in the case of a conversion to, or a continuation of, a Eurodollar Rate Loan). A Notice of Conversion/Continuation shall specify (i) the proposed conversion/continuation date (which shall be a Business Day), (ii) the amount and type of the Loan to be converted/continued, (iii) the nature of the proposed conversion/continuation, (iv) in the case of a conversion to, or a continuation of, a Eurodollar Rate Loan, the requested Interest Period, and (v) in the case of a conversion to, or a continuation of, a Eurodollar Rate Loan, that no Potential Event of Default or Event of Default has occurred and is continuing. In lieu of delivering the above-described Notice of Conversion/Continuation, Company may give Administrative Agent telephonic notice by the required time of any proposed conversion/continuation under this subsection 2.2D; provided that such notice shall be promptly confirmed in writing by delivery of a Notice of Conversion/Continuation to Administrative Agent on or before the proposed conversion/continuation date. Upon receipt of written or telephonic notice of any proposed conversion/continuation under this subsection 2.2D, Administrative Agent shall promptly notify each Lender.

          Neither Administrative Agent nor any Lender shall incur any liability to Company in acting upon any telephonic notice referred to above that Administrative Agent believes in good faith to have been given by a duly authorized officer or other person authorized to act on behalf of Company or for otherwise acting in good faith under this subsection 2.2D, and upon conversion or continuation of the applicable basis for determining the interest rate with respect to any Loans in accordance with this Agreement pursuant to any such telephonic notice Company shall have effected a conversion or continuation, as the case may be, hereunder.

          Except as otherwise provided in subsections 2.6B, 2.6C and 2.6G, a Notice of Conversion/Continuation for conversion to, or continuation of, a Eurodollar Rate Loan (or telephonic notice in lieu thereof) shall be irrevocable and Company shall be bound to effect a conversion or continuation in accordance therewith.

          E. Default Rate. In the event that the outstanding principal amount of any Loan, any interest or any fees or other amounts due and payable hereunder are not paid when due, such overdue amounts shall thereafter bear interest (including post-petition interest in any proceeding under the Bankruptcy Code or other applicable bankruptcy laws) payable upon demand at a rate that is 2% per annum in excess of the interest rate otherwise payable under this Agreement with respect to the applicable Loans (or, in the case of any such fees and other amounts, at a rate which is 2% per annum, in excess of the interest rate otherwise payable under this Agreement for Alternate Base Rate Loans); provided that, in the case of Eurodollar Rate Loans, upon the expiration of the Interest Period in effect at the time any such increase in interest rate is effective such Eurodollar Rate Loans shall thereupon become Alternate Base Rate Loans and shall thereafter bear interest payable upon demand at a rate which is 2% per annum in excess of the interest rate otherwise payable under this Agreement for Alternate Base Rate Loans. Payment or acceptance of the increased rates of interest provided for in this subsection 2.2E is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Administrative Agent or any Lender.

          F. Computation of Interest. Interest on the Loans shall be computed on the basis of (i) in the case of Eurodollar Rate Loans a 360-day year or (ii) in the case of Alternate Base Rate Loans, a 365 or 366-day year, unless the interest rate on such Alternate Base Rate Loans is based on the Federal Funds Rate or the Adjusted Eurodollar Rate, in which case the calculation will be on the basis of a 360-day year, in each case for the actual number of days elapsed in the period during which it accrues. In computing interest on any Loan, the date of the making of such Loan or the first day of an Interest Period applicable to such Loan or, with respect to an Alternate Base Rate Loan being converted from a Eurodollar Rate Loan the date of conversion of such Eurodollar Rate Loan to such Alternate Base Rate Loan, as the case may be, shall be included, and the date of payment of such Loan or the expiration date of an Interest Period applicable to such Loan or, with respect to an Alternate Base Rate Loan being converted to a Eurodollar Rate Loan, the date of conversion of such Base Rate Loan to such Eurodollar Rate Loan, as the case may be, shall be excluded; provided that if a Loan is repaid on the same day on which it is made, one day’s interest shall be paid on that Loan.

          2.3 Fees

          D. Other Fees. Company agrees to pay to an Agent such other fees in the amounts and at the times separately agreed upon between Company and such Agent and the Joint Lead Arrangers.

Company may request, by delivering to Administrative Agent a Notice of Extension (which notice Administrative Agent shall promptly forward to each of the Lenders), on a date (the “Election Date”) occurring no more than 60 nor fewer than 30 days prior to the Original Maturity Date, that the maturity

of up to 50% of the Loans outstanding on the Election Date be extended (the “Extension”) to a date (the “Extended Maturity Date) that is not later than the date three months following the Original Maturity Date and, if Company so requests, then as of the Original Maturity Date, the maturity of such Loans (allocated ratably among the Lenders) shall be extended until the Extended Maturity Date so long as the following conditions shall be satisfied as of the Original Maturity Date:

               (a) receipt by Administrative Agent for the account of the Lenders of an extension fee equal to 1.25% of the aggregate principal amount of the Loans subject to such extension, as well as all other fees, costs and expenses payable by Company under and in respect of this Agreement on or prior to the Original Maturity Date for the account of Administrative Agent or any of the Lenders;

               (b) the representations and warranties contained herein and in the other Loan Documents shall be true, correct and complete in all material respects to the same extent as though made on and as of the Original Maturity Date, except to the extent such representations and warranties specifically relate to an earlier date, in which case such representations and warranties shall have been true, correct and complete in all material respects on and as of such earlier date;

               (c) no event shall have occurred and be continuing or would result from the Extension that would constitute an Event of Default or a Potential Event of Default; and

               (d) Company shall have delivered to Administrative Agent an Officer’s Certificate dated the Original Maturity Date confirming compliance with the conditions set forth in clauses (b) and (c) of this subsection 2.4A(ii).

               (iii) Voluntary Prepayments. Company may, upon not less than one Business Day’s prior written or telephonic notice, in the case of Alternate Base Rate Loans, and three Business Days’ prior written or telephonic notice, in the case of Eurodollar Rate Loans, in each case given to Administrative Agent by 12:00 Noon (New York City time) on the date required and, if given by telephone, promptly confirmed in writing to Administrative Agent (which written or telephonic notice Administrative Agent will promptly transmit by telefacsimile or telephone to each Lender), at any time and from time to time prepay any Loans on any Business Day in whole or in part in an aggregate minimum amount of $10,000,000 and integral multiples of $1,000,000 without premium or penalty; provided, however, that Company shall pay any amounts payable pursuant to subsection 2.6D in connection with any such prepayment other than at the expiration of an Interest Period. Notice of prepayment having been given as aforesaid, the principal amount of the Loans specified in such notice shall become due and payable on the prepayment date specified therein.

               (iv) Voluntary Termination or Reduction of Commitments. Company may, upon not less than one Business Day’s prior written or telephonic notice confirmed in writing to Administrative Agent (which written or telephonic notice Administrative Agent will promptly transmit by telefacsimile or telephonic notice confirmed in writing to each Lender), at any time and from time to time terminate in whole or permanently reduce in part, without premium or penalty, the Commitments; provided that any such partial reduction of the Commitments shall be in an aggregate minimum amount of $10,000,000 and integral multiples of $1,000,000 in excess of that amount. Company’s notice to Administrative Agent shall designate the date (which shall be a Business Day) of such termination or reduction and the amount of any partial reduction, and such termination or reduction of the Commitments shall be effective on the date specified in Company’s notice.

               (v) Pre-Funding Date Syndicated Term Loan Commitments. On the effective date of any Pre-Funding Date Syndicated Term Loan Commitments, the Commitments shall be automatically reduced by an amount equal to the aggregate principal amount of such Pre-Funding Date Syndicated Term Loan Commitments.

               (vi) Mandatory Reductions of Commitments. On the date of any receipt by Company or any of its Subsidiaries after the Closing Date but on or prior to the Funding Date of Net Cash Proceeds in respect of any Prepayment/Reduction Event (other than an Asset Sale), the Commitments shall be automatically reduced by an amount equal to the amount of such Net Cash Proceeds.

               (vii) Mandatory Prepayments. Within five Business Days after the receipt by Company or any of its Subsidiaries of Net Cash Proceeds in respect of any Prepayment/Reduction Event occurring after the Funding Date, Company shall prepay the Loans in an aggregate amount equal to 100% of such Net Cash Proceeds without premium or penalty; provided, however, that Company shall pay any amounts payable pursuant to subsection 2.6D in connection with any such prepayment other than at the expiration of an Interest Period.

               (viii) Application of Prepayments. Any prepayment of Loans shall be applied first to Alternate Base Rate Loans to the full extent thereof before application to Eurodollar Rate Loans, in each case in a manner which minimizes the amount of any payments required to be made by Company pursuant to subsection 2.6D.

               (ix) Effect of Termination or Reduction. Any termination or reduction of the Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders in accordance with their respective Pro Rata Shares; provided, however, that any reduction in the Commitments made pursuant to subsection 2.4A(v) shall be applied first, ratably, to the Commitments of Credit Suisse and Citibank, N.A. (or their respective Affiliates), until an aggregate of $4,000,000,000

of their Commitments shall have been so reduced pursuant to such subsection, and then ratably among the Lenders (including Credit Suisse and Citibank, N.A. and their respective Affiliates) in accordance with their respective Pro Rata Shares.

          B. General Provisions Regarding Payments.

               (i) Manner and Time of Payment. All payments by Company of principal, interest, fees and other Obligations hereunder and under the Notes shall be made in Dollars in same day funds, without defense, setoff or counterclaim, free of any restriction or condition, and delivered to Administrative Agent not later than 12:00 Noon (New York City time) on the date due at the Funding and Payment Office for the account of Lenders; funds received by Administrative Agent after that time on such due date shall be deemed to have been paid by Company on the next succeeding Business Day.

               (ii) Application of Payments to Principal and Interest. Except as provided in subsection 2.2C, all payments in respect of the principal amount of any Loan shall include payment of accrued interest on the principal amount being repaid or prepaid, and all such payments (and, in any event, any payments in respect of any Loan on a date when interest is due and payable with respect to such Loan) shall be applied to the payment of interest before application to principal.

               (iii) Apportionment of Payments. Except as provided above with respect to the ticking fees of Defaulting Lenders, aggregate principal, interest and fee payments in respect of Loans and Commitments shall be apportioned proportionately to Lenders’ respective Pro Rata Shares. Administrative Agent shall promptly distribute to each Lender, at its primary address set forth below its name on the appropriate signature page hereof or at such other address as such Lender may request, its Pro Rata Share of all such payments received by Administrative Agent when received by Administrative Agent and the fees of such Lender when received by Administrative Agent pursuant to subsection 2.3. Notwithstanding the foregoing provisions of this subsection 2.4B(iii), if, pursuant to the provisions of subsection 2.6C, any Notice of Conversion/Continuation is withdrawn as to any Affected Lender or if any Affected Lender makes Alternate Base Rate Loans in lieu of its Pro Rata Share of any Eurodollar Rate Loans, Administrative Agent shall give effect thereto in apportioning payments received thereafter.

               (iv) Payments on Business Days. Except as otherwise expressly provided herein, whenever any payment to be made hereunder shall be stated to be due on a day that is not a Business Day, such payment shall be made on the next succeeding Business Day and such extension of time shall be included in the computation of the payment of interest hereunder.

               (v) Notation of Payment. Each Lender agrees that before disposing of any Note held by it, or any part thereof (other than by granting participations therein), that Lender will make a notation thereon of all Loans evidenced by that Note and all principal payments previously made thereon and of the date to which interest thereon has been paid; provided that the failure to make (or any error in the making of) a notation of any Loan made under such Note shall not limit or otherwise affect the obligations of Company hereunder or under such Note with respect to any Loan or any payments of principal or interest on such Note.

          C. Payments Under Subsidiary Guaranty. All payments received by Administrative Agent under the Subsidiary Guaranty shall be applied promptly from time to time by Administrative Agent in the following order of priority:

               (i) to the payment of the costs and expenses of any collection or other realization under the Subsidiary Guaranty, including reasonable compensation to Administrative Agent and its agents and counsel, and all expenses, liabilities and advances made or incurred by Administrative Agent in connection therewith, all in accordance with the terms of this Agreement and the Subsidiary Guaranty;

               (ii) thereafter, to the extent of any excess such payments, to the payment of all other Guarantied Obligations (as defined in the Subsidiary Guaranty) for the ratable benefit of the holders thereof; and

               (iii) thereafter, to the extent of any excess such payments, to the payment to the applicable Subsidiary Guarantor or to whosoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct.

          2.5 Use of Proceeds

          A. Loans. The proceeds of the Loans made on the Funding Date shall be used solely to finance, in part, the Acquisition and the Refinancing and to pay fees and expenses in connection with the Transactions.

          B. Margin Regulations. No portion of the proceeds of any borrowing under this Agreement shall be used by Company or any of its Subsidiaries in any manner that might cause the borrowing or the application of such proceeds to violate Regulation U, Regulation T or Regulation X of the Board of Governors of the Federal Reserve System or any other regulation of such Board or to violate the Exchange Act, in each case as in effect on the date or dates of such borrowing and such use of proceeds.

          2.6 Special Provisions Governing Eurodollar Rate Loans

          Notwithstanding any other provision of this Agreement to the contrary, the following provisions shall govern with respect to Eurodollar Rate Loans as to the matters covered:

          A. Determination of Applicable Interest Rate. As soon as practicable after 11:00 A.M. (London time) on each Interest Rate Determination Date, Administrative Agent shall determine (which determination shall, absent manifest error, be final, conclusive and binding upon all parties) the interest rate that shall apply to the Eurodollar Rate Loans for which an interest rate is then being determined for the applicable Interest Period and shall promptly give notice thereof (in writing or by telephone confirmed in writing) to Company and each Lender.

          B. Inability to Determine Applicable Interest Rate. In the event that Administrative Agent shall have determined (which determination shall be final and conclusive and binding upon all parties hereto), on any Interest Rate Determination Date with respect to any Eurodollar Rate Loans, that by reason of circumstances affecting the interbank Eurodollar market adequate and fair means do not exist for ascertaining the interest rate applicable to such Loans on the basis provided for in the definition of Adjusted Eurodollar Rate, Administrative Agent shall on such date give notice (by telefacsimile or by telephone confirmed in writing) to Company and each Lender of such determination, whereupon (i) no Loans may be made as, or converted to, Eurodollar Rate Loans until such time as Administrative Agent notifies Company and Lenders that the circumstances giving rise to such notice no longer exist and (ii) any Notice of Borrowing or Notice of Conversion/Continuation given by Company with respect to the Loans in respect of which such determination was made shall be deemed to be rescinded by Company.

          C. Illegality of Eurodollar Rate Loans. In the event that on any date any Lender shall have determined (which determination shall be final and conclusive and binding upon all parties hereto but shall be made only after consultation with Administrative Agent) that the making, maintaining or continuation of its Eurodollar Rate Loans has become unlawful as a result of compliance by such Lender in good faith with any law, treaty, governmental rule, regulation, guideline or order which came into effect after the Closing Date (or would conflict with any such treaty, governmental rule, regulation, guideline or order not having the force of law even though the failure to comply therewith would not be unlawful), then, and in any such event, such Lender shall be an “Affected Lender” and it shall on that day give notice (by telefacsimile or by telephone confirmed in writing) to Company and Administrative Agent of such determination (which notice Administrative Agent shall promptly transmit to each other Lender). Thereafter (a) the obligation of the Affected Lender to make Loans as, or to convert Loans to, Eurodollar Rate Loans shall be suspended until such notice shall be withdrawn by the Affected Lender, (b) to the extent such determination by the Affected Lender relates to a Eurodollar Rate Loan then being requested by Company pursuant to a Notice of Borrowing or a Notice of Conversion/Continuation, the Affected Lender shall make such Loan as (or convert such Loan to, as the case may be) an Alternate Base Rate Loan, (c) the Affected Lender’s obligation to maintain its outstanding Eurodollar Rate Loans (the “Affected Loans”) shall be terminated at the earlier to occur of the expiration of the Interest Period then in effect with

respect to the Affected Loans or when required by law, and (d) the Affected Loans shall automatically convert into Alternate Base Rate Loans on the date of such termination. Notwithstanding the foregoing, to the extent a determination by an Affected Lender as described above relates to a Eurodollar Rate Loan then being requested by Company pursuant to a Notice of Borrowing or a Notice of Conversion/Continuation, Company shall have the option, subject to the provisions of subsection 2.6D, to rescind such Notice of Borrowing or Notice of Conversion/Continuation as to all Lenders by giving notice (by telefacsimile or by telephone confirmed in writing) to Administrative Agent of such rescission on the date on which the Affected Lender gives notice of its determination as described above (which notice of rescission Administrative Agent shall promptly transmit to each other Lender). Except as provided in the immediately preceding sentence, nothing in this subsection 2.6C shall affect the obligation of any Lender other than an Affected Lender to make or maintain Loans as, or to convert Loans to, Eurodollar Rate Loans in accordance with the terms of this Agreement.

          D. Compensation for Breakage or Non-Commencement of Interest Periods. Company shall compensate each Lender, upon written request by that Lender (which request shall set forth in reasonable detail the basis for requesting such amounts), for all reasonable losses, expenses and liabilities (including any interest paid by that Lender to lenders of funds borrowed by it to make or carry its Eurodollar Rate Loans and any loss, expense or liability sustained by that Lender in connection with the liquidation or re-employment of such funds, but excluding loss of profit) which that Lender may sustain: (i) if for any reason (other than a default by that Lender) a borrowing of any Eurodollar Rate Loan does not occur on a date specified therefor in a Notice of Borrowing or a telephonic request for borrowing, or a conversion to or continuation of any Eurodollar Rate Loan does not occur on a date specified therefor in a Notice of Conversion/Continuation or a telephonic request for conversion or continuation, (ii) if any prepayment (including any prepayment pursuant to subsection 2.4A(iii) or 2.4A(vii) or by virtue of the replacement of any Lender pursuant to subsection 2.8B or 10.6B) or other principal payment or any conversion of any of its Eurodollar Rate Loans occurs on a date prior to the last day of an Interest Period applicable to that Loan, (iii) if any prepayment of any of its Eurodollar Rate Loans is not made on any date specified in a notice of prepayment given by Company, or (iv) as a consequence of any other default by Company in the repayment of its Eurodollar Rate Loans when required by the terms of this Agreement.

          E. Booking of Eurodollar Rate Loans. Any Lender may make, carry or transfer Eurodollar Rate Loans at, to, or for the account of any of its branch offices or the office of an Affiliate of that Lender; provided, that such making, carrying or transferring Eurodollar Rate Loans does not result in any costs or taxes to Company pursuant to subsection 2.7.

          F. Assumptions Concerning Funding of Eurodollar Rate Loans. Calculation of all amounts payable to a Lender under this subsection 2.6 and under subsection 2.7A shall be made as though that Lender had actually funded each of its relevant Eurodollar Rate Loans through the purchase of a Eurodollar deposit bearing interest at the rate obtained pursuant to the definition of Eurodollar Rate in an amount equal to the amount of such Eurodollar Rate Loan and having a maturity comparable to the relevant Interest Period and through the transfer of such

Eurodollar deposit from an offshore office of that Lender to a domestic office of that Lender in the United States of America; provided, however, that each Lender may fund each of its Eurodollar Rate Loans in any manner it sees fit and the foregoing assumptions shall be utilized only for the purposes of calculating amounts payable under this subsection 2.6 and under subsection 2.7A.

          G. Eurodollar Rate Loans After Default. After the occurrence of and during the continuation of a Potential Event of Default or an Event of Default if notified by Administrative Agent or the Requisite Lenders, (i) Company may not elect to have a Loan be made or maintained as, or converted to, a Eurodollar Rate Loan after the expiration of any Interest Period then in effect for that Loan and (ii) subject to the provisions of subsection 2.6D, any Notice of Borrowing of Eurodollar Loans or Notice of Conversion/Continuation which would result in Eurodollar Loans being outstanding given by Company with respect to a requested borrowing or conversion/continuation that has not yet occurred shall be deemed to be rescinded by Company.

          2.7 Increased Costs; Taxes; Capital Adequacy

          A. Compensation for Increased Costs and Taxes. Subject to the provisions of subsection 2.7B (which shall be controlling with respect to the matters covered thereby), in the event that any Lender shall determine (which determination shall, absent manifest error, be final and conclusive and binding upon all parties hereto) that any law, treaty or governmental rule, regulation or order, or any change therein or in the interpretation, administration or application thereof (including the introduction of any new law, treaty or governmental rule, regulation or order), or any determination of a Governmental Authority, in each case that becomes effective after the date hereof (and, for purposes of this Agreement, (x) the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, guidelines or directives in connection therewith and (y) all requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel III, are deemed to have gone into effect and adopted after the date hereof), or compliance by such Lender with any guideline, request or directive issued or made after the date hereof by any Governmental Authority (whether or not having the force of law):

               (i) subjects such Lender (or its applicable lending office) to any additional Tax (other than any Tax on the Overall Net Income of such Lender) with respect to this Agreement or any of its obligations hereunder or any payments to such Lender (or its applicable lending office) of principal, interest, fees or any other amount payable hereunder;

               (ii) imposes, modifies or holds applicable any reserve (including any marginal, emergency, supplemental, special or other reserve), special deposit, compulsory loan, FDIC insurance or similar requirement against assets held by,

or deposits or other liabilities in or for the account of, or advances or loans by, or other credit extended by, or any other acquisition of funds by, any office of such Lender (other than any such reserve or other requirements with respect to Eurodollar Rate Loans that are reflected in the definition of Adjusted Eurodollar Rate); or

               (iii) imposes any other condition (other than with respect to a Tax matter) on or affecting such Lender (or its applicable lending office) or its obligations hereunder or the interbank Eurodollar market; and the result of any of the foregoing is to increase the cost to such Lender of agreeing to make, making or maintaining Loans hereunder or to reduce any amount received or receivable by such Lender (or its applicable lending office) with respect thereto; then, in any such case, Company shall promptly pay to such Lender, upon receipt of the statement referred to in the next sentence, such additional amount or amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as such Lender in its sole discretion shall determine) as may be necessary to compensate such Lender for any such increased cost or reduction in amounts received or receivable hereunder; provided that Company shall not be required to compensate a Lender pursuant to this subsection for any increased cost or reduction incurred more than 180 days prior to the date that such Lender notifies Company of such change giving rise to such increased cost or reduction and of such Lender’s intention to claim compensation therefor; provided, further, that, if such change giving rise to such increased cost or reduction is retroactive, then the 180 day period referred to above shall be extended to include the period of retroactive effect thereof. Such Lender shall deliver to Company (with a copy to Administrative Agent) a written statement, setting forth in reasonable detail the basis for calculating the additional amounts owed to such Lender under this subsection 2.7A, which statement shall be conclusive and binding upon all parties hereto absent manifest error.

          B. Withholding of Taxes.

               (i) Payments to Be Free and Clear. All sums payable by Company under this Agreement and the other Loan Documents shall (except to the extent required by law) be paid free and clear of, and without any deduction or withholding on account of, any Tax (other than a Tax on the Overall Net Income of any Lender or a Tax measured by or imposed as a result of the extent and nature of a Lender’s activities, assets, liabilities, leverage, other exposures to risk or other similar factors) imposed, levied, collected, withheld or assessed by or within the United States of America or any political subdivision in or of the United States of America or any other jurisdiction from or to which a payment is made by or on behalf of Company or by any federation or organization of which the United States of America or any such jurisdiction is a member at the time of payment.

               (ii) Grossing-Up of Payments. If Company or any other Person is required by law to make any deduction or withholding on account of any such Tax

from any sum paid or payable by Company to Administrative Agent or any Lender under any of the Loan Documents:

               (a) Company shall notify Administrative Agent of any such requirement or any change in any such requirement as soon as Company becomes aware of it;

               (b) Company shall pay any such Tax before the date on which penalties attach thereto, such payment to be made (if the liability to pay is imposed on Company) for its own account or (if that liability is imposed on Administrative Agent or such Lender, as the case may be) on behalf of and in the name of Administrative Agent or such Lender;

               (c) the sum payable by Company in respect of which the relevant deduction, withholding or payment is required shall be increased to the extent necessary to ensure that, after the making of that deduction, withholding or payment, Administrative Agent or such Lender, as the case may be, receives on the due date a net sum equal to what it would have received had no such deduction, withholding or payment been required or made; and

               (d) within 30 days after paying any sum from which it is required by law to make any deduction or withholding, and within 30 days after the due date of payment of any Tax which it is required by clause (b) above to pay, Company shall deliver to Administrative Agent evidence satisfactory to the other affected parties of such deduction, withholding or payment and of the remittance thereof to the relevant taxing or other authority;

provided that no such additional amount shall be required to be paid to any Lender under clause (c) above except to the extent that any change in any law, treaty or governmental rule, regulation or order, or any change therein or in the interpretation, administration or application thereof (including the introduction of any new law, treaty or governmental rule, regulation or order), or any determination of a Governmental Authority, in each case that becomes effective after the date hereof (in the case of each Lender listed on the signature pages hereof) or after the date of the Assignment Agreement pursuant to which such Lender became a Lender (in the case of each other Lender) affecting any such requirement for a deduction, withholding or payment as is mentioned therein shall result in an increase in the rate of such deduction, withholding or payment from that in effect at the date of this Agreement or at the date of such Assignment Agreement, as the case may be, in respect of payments to such Lender. With respect to FATCA, any regulations or official interpretations issued after the date hereof (in the case of each Lender listed on the signature pages hereof) or after the date of the Assignment Agreement pursuant to which such Lender became a Lender (in the case of each other Lender) shall be considered as law in effect on such date, as the case may be.

               (iii) Evidence of Exemption From Withholding Tax.

               (a) Each Lender that is not a United States person as defined in Section 7701(a)(30) of the Internal Revenue Code (for purposes of this subsection 2.7B(iii), a “Non-US Lender”) shall deliver to Administrative Agent for transmission to Company, on or prior to the Closing Date (in the case of each Lender listed on the signature pages hereof) or on or prior to the date of the Assignment Agreement pursuant to which it becomes a Lender (in the case of each other Lender), and at such other times as may be necessary in the determination of Company or Administrative Agent (each in the reasonable exercise of its discretion), (1) two original copies of Internal Revenue Service Form W-8BEN, Form W-8ECI or Form W-8IMY, as the case may be (or any successor forms), properly completed and duly executed by such Lender, together with any other certificate or statement of exemption required under the Internal Revenue Code or the regulations issued thereunder to establish that such Lender is not subject to deduction or withholding of United States federal income tax with respect to any payments to such Lender of principal, interest, fees or other amounts payable under any of the Loan Documents or (2) if such Lender is not a “bank” or other Person described in Section 881(c)(3) of the Internal Revenue Code, a Certificate re Non-Bank Status together with two original copies of Internal Revenue Service Form W-8BEN or W-8IMY (or any successor form), properly completed and duly executed by such Lender, together with any other certificates or statements of exemption requested by Company required under the Internal Revenue Code or the regulations issued thereunder to establish that such Lender is not subject to deduction or withholding of United States federal income tax with respect to any payments to such Lender of interest payable under any of the Loan Documents. Each Lender that is a “United States person” within the meaning of Section 7701(a)(30) of the Internal Revenue Code shall deliver to Administrative Agent for transmission to Company, on or prior to the Closing Date (in the case of each Lender listed on the signature pages hereof) or on or prior to the date of the Assignment Agreement pursuant to which it becomes a Lender (in the case of each other Lender), and at such other times as it may be necessary in the determination of Company or Administrative Agent (each in the reasonable exercise of its discretion), two copies of executed originals of Internal Revenue Service Form W-9 or such other documentation or information prescribed by applicable laws or reasonably requested by Company or Administrative Agent as will enable Company or Administrative Agent, as the case may be, to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

               (b) Each Lender required to deliver any forms, certificates or other evidence with respect to United States federal income tax withholding matters pursuant to subsection 2.7B(iii)(a) hereby agrees, from time to time after the initial delivery by such Lender of such forms, certificates or other evidence, whenever a lapse in time or change in circumstances renders such forms, certificates or other evidence obsolete or inaccurate in any material respect, that such Lender shall promptly (1) deliver to Administrative Agent for transmission to Company two new original copies of Internal Revenue Service Form W-8BEN, W-8ECI or W-8IMY, as the case may be, or a

Certificate re Non-Bank Status and two original copies of Internal Revenue Service Form W-8BEN or W-8IMY, as the case may be, properly completed and duly executed by such Lender, together with any other certificates or statements of exemption requested by Company required in order to confirm or establish that such Lender is not subject to deduction or withholding of United States federal income tax with respect to payments to such Lender under the Loan Documents or (2) notify Administrative Agent and Company of its inability to deliver any such forms, certificates or other evidence.

               (c) Company shall not be required to pay any additional amount to any Lender under clause (c) of subsection 2.7B(ii) if such Lender shall have failed to satisfy the requirements of clause (a), (b)(1) or (d) of this subsection 2.7B(iii); provided that if such Lender shall have satisfied the requirements of subsection 2.7B(iii)(a) on the Closing Date (in the case of each Lender listed on the signature pages hereof) or on the date of the Assignment Agreement pursuant to which it became a Lender (in the case of each other Lender), nothing in this subsection 2.7B(iii)(c) shall relieve Company of its obligation to pay any additional amounts pursuant to clause (c) of subsection 2.7B(ii) in the event that, as a result of any change in any applicable law, treaty or governmental rule, regulation or order, or any change in the interpretation, administration or application thereof, such Lender is no longer properly entitled to deliver forms, certificates or other evidence at a subsequent date establishing the fact that such Lender is not subject to withholding as described in subsection 2.7B(iii)(a).

               (d) If a payment made to a Lender under this Agreement would be subject to U.S. Federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Internal Revenue Code, as applicable), such Lender shall deliver to the Withholding Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Withholding Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code) and such additional documentation reasonably requested by the Withholding Agent as may be necessary for the Withholding Agent to comply with its obligations under FATCA, to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. For purposes of this subsection 2.7B(iii)(d), FATCA shall include any regulations or official interpretations thereof.

          C. Capital Adequacy Adjustment. If any Lender shall have determined that the adoption, effectiveness, phase-in or applicability after the date hereof of any law, rule or regulation (or any provision thereof) regarding capital adequacy, or any change therein or in the interpretation or administration thereof by any Governmental Authority charged with the interpretation or administration thereof, or compliance by any Lender (or its applicable lending office) with any guideline, request or directive regarding capital adequacy (whether or not having the force of law) of any such Governmental Authority has or would have the effect of reducing the rate of return on the capital of such Lender or any corporation controlling such Lender as a

consequence of, or with reference to, such Lender’s Loans or Commitments or other obligations hereunder with respect to the Loans to a level below that which such Lender or such controlling corporation could have achieved but for such adoption, effectiveness, phase-in, applicability, change or compliance (taking into consideration the policies of such Lender or such controlling corporation with regard to capital adequacy), then from time to time, within five Business Days after receipt by Company from such Lender of the statement referred to in the next sentence, Company shall pay to such Lender such additional amount or amounts as will compensate such Lender or such controlling corporation on an after-tax basis for such reduction; provided that Company shall not be required to compensate a Lender pursuant to this subsection for any reduction incurred more than 180 days prior to the date that such Lender notifies Company of such change giving rise to such reduction and of such Lender’s intention to claim compensation therefor; provided, further, that, if such change giving rise to such reduction is retroactive, then the 180 day period referred to above shall be extended to include the period of retroactive effect thereof. Such Lender shall deliver to Company (with a copy to Administrative Agent) a written statement, setting forth in reasonable detail the basis of the calculation of such additional amounts, which statement shall be conclusive and binding upon all parties hereto absent manifest error.

          D. Refund and Contest. If Administrative Agent or any Lender receives a refund with respect to Tax deducted, withheld or paid by Company and with respect to which Company has been required to and has paid an additional amount under this subsection 2.7, which in the good faith judgment of such Lender is allocable to such deduction, withholding or payment, it shall promptly pay such refund, together with any other amount paid by Company in connection with such refunded Tax and any interest paid by the relevant Governmental Authority with respect to such refund, to Company, net of all unreimbursed out-of-pocket expenses of such Lender incurred in obtaining such refund, provided, however, that Company agrees to promptly return such refund to Administrative Agent or the applicable Lender, as the case may be, if it receives notice from Administrative Agent or applicable Lender that such Administrative Agent or Lender is required to repay such refund. Each of Administrative Agent and such Lender agrees that it will contest such Tax or liabilities paid by Company if Administrative Agent or such Lender determines, in its sole discretion, that it would not be materially disadvantaged or prejudiced as a result of such contest.

          2.8 Obligation of Lenders to Mitigate; Replacement

          A. Mitigation. Each Lender agrees that, as promptly as practicable after the officer of such Lender responsible for administering the Loans of such Lender becomes aware of the occurrence of an event or the existence of a condition that would cause such Lender to become an Affected Lender or that would entitle such Lender to receive payments under subsection 2.7, it will, to the extent not inconsistent with the internal policies of such Lender and any applicable legal or regulatory restrictions, use reasonable efforts (i) to make, issue, fund or maintain the Commitments of such Lender or the affected Loans of such Lender through another lending office of such Lender, or (ii) take such other measures as such Lender may deem reasonable, which may include assignment of its rights and obligations hereunder to another of

its offices, branches or affiliates, if as a result thereof the circumstances which would cause such Lender to be an Affected Lender would cease to exist or the additional amounts which would otherwise be required to be paid to such Lender pursuant to subsection 2.7 would be materially reduced and if, as determined by such Lender in its sole discretion, the making, issuing, funding or maintaining of such Commitments or Loans through such other lending office or in accordance with such other measures, including assignment, as the case may be, would not otherwise materially adversely affect such Commitments or Loans or the interests of such Lender; provided that such Lender will not be obligated to utilize such other lending office pursuant to this subsection 2.8 unless Company agrees to pay all reasonable incremental expenses incurred by such Lender as a result of utilizing such other lending office as described in clause (i) above. A certificate as to the amount of any such expenses payable by Company pursuant to this subsection 2.8 (setting forth in reasonable detail the basis for requesting such amount) submitted by such Lender to Company (with a copy to Administrative Agent) shall be conclusive absent manifest error.

          B. Replacement. In the event of (a) a refusal by a Lender to consent to a proposed change, waiver, discharge or termination with respect to this Agreement which has been approved by Requisite Lenders (but requires consent of all Lenders) as provided in subsection 10.6, (b) any Lender becomes an Affected Lender or requests compensation under subsection 2.7A or 2.7C, (c) Company is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to subsection 2.7B, or (d) any Lender becomes a Defaulting Lender, then Company may, at its sole expense and effort, replace such Lender (a “Replaced Lender”) with one or more Eligible Assignees (collectively, the “Replacement Lender”) reasonably acceptable to Administrative Agent, provided that (i) at the time of any replacement pursuant to this subsection 2.8 the Replacement Lender shall enter into one or more Assignment Agreements pursuant to subsection 10.1B (and with all fees payable pursuant to such subsection 10.1B to be paid by the Replacement Lender) pursuant to which the Replacement Lender shall acquire all of the outstanding Loans and Commitments of the Replaced Lender and, in connection therewith, shall pay to the Replaced Lender in respect thereof an amount equal to the sum of (A) an amount equal to the principal of, and all accrued interest on, all outstanding Loans of the Replaced Lender and (B) an amount equal to all accrued, but theretofore unpaid, fees owing to the Replaced Lender with respect thereto and (ii) all obligations (including without limitation all such amounts, if any, owing under subsection 2.6D) of Company owing to the Replaced Lender (other than those specifically described in clause (i) above in respect of which the assignment purchase price has been, or is concurrently being, paid), shall be paid in full to such Replaced Lender concurrently with such replacement. Upon the execution of the respective Assignment Agreements and the acceptance thereof by Administrative Agent pursuant to subsection 10.1B, the payment of amounts referred to in clauses (i) and (ii) above and, if so requested by the Replacement Lender, delivery to the Replacement Lender of the appropriate Note or Notes executed by Company, the Replacement Lender shall become a Lender hereunder and the Replaced Lender shall cease to constitute a Lender hereunder except with respect to indemnification provisions under this Agreement which by the terms of this Agreement survive the termination of this Agreement, which indemnification provisions shall survive as to such Replaced Lender. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or

otherwise, the circumstances entitling Company to require such assignment and delegation cease to apply.

          B. Qualification and Good Standing. Each Loan Party is qualified to do business and in good standing in every jurisdiction where its assets are located and wherever necessary to carry out its business and operations, except in jurisdictions where the failure to be so qualified or in good standing has not had and could not reasonably be expected to have a Material Adverse Effect.

Company knows of no proposed material Tax assessment against Company or any of its Subsidiaries which is not being actively contested by Company or such Subsidiary in good faith and by appropriate proceedings; provided that reserves or other appropriate provisions, if any, as shall be required in conformity with GAAP shall have been made or provided therefor.

          D. For each Multiemployer Plan as of the most recent valuation date for which an actuarial report has been received, the potential liability of Company, its Subsidiaries and their respective ERISA Affiliates for a complete withdrawal from such Multiemployer Plan (within the meaning of Section 4203 of ERISA), when aggregated with such potential liability for a complete withdrawal from all Multiemployer Plans, based on information available pursuant to Section 4221(e) of ERISA, would not reasonably be expected to result in a Material Adverse Effect.

Any projections and pro forma financial information contained in such materials are based upon good faith estimates and assumptions believed by Company to be reasonable at the time made, it being recognized by Lenders that such projections as to future events are not to be viewed as facts and that actual results during the period or periods covered by any such projections may differ from the projected results.

          9.2 Powers and Duties; General Immunity

          A. Powers; Duties Specified. Each Lender irrevocably authorizes Administrative Agent to take such action on such Lender’s behalf and to exercise such powers, rights and remedies hereunder and under the other Loan Documents as are specifically delegated or granted to Administrative Agent by the terms hereof and thereof, together with such powers, rights and remedies as are reasonably incidental thereto. Administrative Agent shall have only those duties and responsibilities that are expressly specified in this Agreement and the other Loan Documents. Administrative Agent may exercise such powers, rights and remedies and perform such duties by or through its agents or employees. Administrative Agent shall not have, by reason of this Agreement or any of the other Loan Documents, a fiduciary relationship in respect of any Lender; and nothing in this Agreement or any of the other Loan Documents, expressed or implied, is intended to or shall be so construed as to impose upon Administrative Agent any obligations in respect of this Agreement or any of the other Loan Documents except as expressly set forth herein or therein.

          B. No Responsibility for Certain Matters. Administrative Agent shall not be responsible to any Lender for the execution, effectiveness, genuineness, validity, enforceability, collectibility or sufficiency of this Agreement or any other Loan Document or for any representations, warranties, recitals or statements made herein or therein or made in any written or oral statements or in any financial or other statements, instruments, reports or certificates or any other documents furnished or made by Administrative Agent to Lenders or by or on behalf of Company to Administrative Agent or any Lender in connection with the Loan Documents and the transactions contemplated thereby or for the financial condition or business affairs of Company or any other Person liable for the payment of any Obligations, nor shall Administrative Agent be required to ascertain or inquire as to the performance or observance of any of the terms, conditions, provisions, covenants or agreements contained in any of the Loan Documents or as to the use of the proceeds of the Loans or as to the existence or possible existence of any Event of Default or Potential Event of Default.

          C. Exculpatory Provisions. Neither Administrative Agent nor any of its officers, directors, employees or agents shall be liable to Lenders for any action taken or omitted by it under or in connection with any of the Loan Documents except to the extent caused by Administrative Agent’s gross negligence or willful misconduct. Administrative Agent shall be entitled to refrain from any act or the taking of any action (including the failure to take an action) in connection with this Agreement or any of the other Loan Documents or from the exercise of any power, discretion or authority vested in it hereunder or thereunder unless and until Administrative Agent shall have received instructions in respect thereof from Requisite Lenders (or such other Lenders as may be required to give such instructions under subsection 10.6) and, upon receipt of such instructions from Requisite Lenders (or such other Lenders, as the case may be), Administrative Agent shall be entitled to act or (where so instructed) refrain from acting, or to exercise such power, discretion or authority, in accordance with such instructions. Administrative Agent shall be deemed to have no knowledge of any Potential Event of Default unless and until written notice thereof is given to Administrative Agent by Company or any Lender. Without prejudice to the generality of the foregoing, (i) Administrative Agent shall be

entitled to rely, and shall be fully protected in relying, upon any communication, instrument or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and shall be entitled to rely and shall be protected in relying on opinions and judgments of attorneys (who may be attorneys for Company and its Subsidiaries), accountants, experts and other professional advisors selected by it; and (ii) no Lender shall have any right of action whatsoever against Administrative Agent as a result of Administrative Agent acting or (where so instructed) refraining from acting under this Agreement or any of the other Loan Documents in accordance with the instructions of Requisite Lenders (or such other Lenders as may be required to give such instructions under subsection 10.6).

          D. Administrative Agent Entitled to Act as Lender. The agency hereby created shall in no way impair or affect any of the rights and powers of, or impose any duties or obligations upon, Administrative Agent in its individual capacity as a Lender hereunder. With respect to its Loans, Administrative Agent shall have the same rights and powers hereunder as any other Lender and may exercise the same as though it were not performing the duties and functions delegated to it hereunder, and the term “Lender” or “Lenders” or any similar term shall, unless the context clearly otherwise indicates, include Administrative Agent in its individual capacity. Administrative Agent and its Affiliates may accept deposits from, lend money to and generally engage in any kind of banking, trust, financial advisory or other business with Company or any of its Affiliates as if it were not performing the duties specified herein, and may accept fees and other consideration from Company for services in connection with this Agreement and otherwise without having to account for the same to Lenders.

          9.3 Representations and Warranties; No Responsibility for Appraisal of Creditworthiness

          Each Lender represents and warrants that it has made its own independent investigation of the financial condition and affairs of Company and its Subsidiaries in connection with the making of the Loans hereunder and that it has made and shall continue to make its own appraisal of the creditworthiness of Company and its Subsidiaries. Administrative Agent shall not have any duty or responsibility, either initially or on a continuing basis, to make any such investigation or any such appraisal on behalf of Lenders or to provide any Lender with any credit or other information with respect thereto, whether coming into its possession before the making of the Loans or at any time or times thereafter, and Administrative Agent shall not have any responsibility with respect to the accuracy of or the completeness of any information provided to Lenders.

          9.4 Right to Indemnity

          Each Lender, in proportion to its Pro Rata Share, severally agrees to indemnify Administrative Agent, to the extent that Administrative Agent shall not have been reimbursed by Company, for and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses (including counsel fees and disbursements) or disbursements of

any kind or nature whatsoever which may be imposed on, incurred by or asserted against Administrative Agent in exercising its powers, rights and remedies or performing its duties hereunder or under the other Loan Documents or otherwise in its capacity as Administrative Agent, in any way relating to or arising out of this Agreement or the other Loan Documents; provided 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 such Administrative Agent’s gross negligence or willful misconduct. If any indemnity furnished to an Administrative Agent for any purpose shall, in the opinion of such Administrative Agent, be insufficient or become impaired, such Administrative Agent may call for additional indemnity and cease, or not commence, to do the acts indemnified against until such additional indemnity is furnished.

          9.5 Successor Agent

          Administrative Agent may resign at any time by giving 30 days’ prior written notice thereof to Lenders and Company. Upon any such notice of resignation, Requisite Lenders shall have the right, with, so long as no Potential Event of Default or Event of Default shall have occurred and be continuing, the consent of Company (not to be unreasonably withheld or delayed), to appoint a successor. If no successor shall have been so appointed by the Requisite Lenders and shall have accepted such appointment within 30 days after the resigning Administrative Agent gives notice of its resignation, then the resigning Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. If no successor Administrative Agent has been appointed pursuant to the immediately preceding sentence by the 30th day after the date such notice of resignation was given by such Administrative Agent, such Administrative Agent’s resignation shall become effective and the Requisite Lenders shall thereafter perform all the duties of such Administrative Agent hereunder and/or under any other Loan Document until such time, if any, as the Requisite Lenders appoint a successor Administrative Agent. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, that successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, as the case may be, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Section 9 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.

          9.6 Guarantees

          Each Lender hereby further authorizes Administrative Agent, on behalf of and for the benefit of Lenders, to be the agent for and representative of Lenders under the Subsidiary Guaranty, and each Lender agrees to be bound by the terms of the Subsidiary Guaranty; provided that Administrative Agent shall not enter into or consent to any amendment, modification, termination or waiver of any provision contained in the Subsidiary Guaranty; provided further,

however, that, without further written consent or authorization from Lenders, Administrative Agent may execute any documents or instruments necessary to release any Subsidiary Guarantor from the Subsidiary Guaranty if all of the capital stock of such Subsidiary Guarantor is sold to any Person pursuant to a sale or other disposition permitted hereunder or to which Requisite Lenders have otherwise consented. Anything contained in any of the Loan Documents to the contrary notwithstanding, Company, Administrative Agent and each Lender hereby agree that no Lender shall have any right individually to enforce the Subsidiary Guaranty, it being understood and agreed that all rights and remedies under the Subsidiary Guaranty may be exercised solely by Administrative Agent for the benefit of Lenders in accordance with the terms thereof.

     Section 10. MISCELLANEOUS

          A. General. Subject to subsection 10.1B, each Lender shall have the right at any time to (i) sell, assign or transfer to any Eligible Assignee, or (ii) sell participations to any Person (a “Participant”) in, all or any part of its Commitments or any Loan or Loans made by it or in any case its rights or obligations with respect thereto or participations therein or any other interest herein or in any other obligations owed to it; provided, further, that no such sale, assignment or transfer described in clause (i) above shall be effective unless and until an Assignment Agreement effecting such sale, assignment or transfer shall have been accepted by Administrative Agent and recorded in the Register as provided in subsection 10.1B(ii).

Each Lender that sells a participation to any Participant shall, acting solely for this purpose as a non-fiduciary agent of Company, maintain a register on which it enters the name and address of each Participant and the principal and interest amounts of each Participant’s interest in the Loans or other obligations under this Agreement (a “Participant Register”). The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Participant whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary; provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register to Company or any other Person (including the identity of any Participant or any information relating to a Participant’s interest under the Loan Documents) except to the extent that such disclosure is necessary to establish that the Loans or other obligations under the Loan Documents are in registered form under Section 5f.103-1(c) of the United States Treasury Regulations.

If Company has not responded within ten Business Days to any request for an assignment, Company shall be deemed to have consented to such assignment. To the extent of any such assignment in accordance with the above, the assigning Lender shall be relieved of its obligations with respect to its Commitments, Loans or other obligations or the portion thereof so assigned. The parties to each such assignment shall (i) electronically execute and deliver to Administrative Agent an Assignment Agreement via an electronic settlement system acceptable to Administrative Agent (which initially shall be ClearPar, LLC) or (ii) manually execute and deliver to Administrative Agent an Assignment Agreement, in each case, together with a (x) processing and recordation fee of US$3,500 (which may be reduced or waived in the sole discretion of Administrative Agent), (y) an Administrative Questionnaire, substantially in the form of Exhibit VIII annexed hereto, if the Eligible Assignee shall not already be a Lender hereunder and (z) such forms, certificates or other evidence, if any, with respect to United States federal income tax withholding matters as the assignee under such Assignment Agreement may be required to deliver to Administrative Agent pursuant to subsection 2.7B(iii)(a). Upon such execution, delivery, acceptance and recordation, from and after the effective date specified in such Assignment Agreement, (y) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment Agreement, shall have the rights and obligations of a Lender hereunder and (z) the assigning Lender thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment Agreement, relinquish its rights (other than any rights which survive the termination of this Agreement under subsection 10.9B) and be released from its obligations under this Agreement (and, in the case of an Assignment Agreement covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto. The Commitments hereunder shall be modified to reflect the Commitment of such assignee and any remaining Commitment of such assigning Lender and, if any such assignment occurs after the issuance of the Notes hereunder, the assigning Lender shall, upon the effectiveness of such assignment or as promptly thereafter as practicable, surrender its Note to Administrative Agent for cancellation, and thereupon a new Note shall be issued to the assignee and/or to the assigning Lender, substantially in the form of Exhibit IV annexed hereto, as the case may be, with appropriate insertions, to reflect the new Commitments and/or outstanding Loans, as the case may be, of the assignee and/or the assigning Lender.

               (ii) Acceptance by Administrative Agent; Recordation in Register.

The Register shall be available for inspection by Company and any Lender at any reasonable time and from time to time upon reasonable prior notice. Administrative Agent shall maintain a copy of each Assignment Agreement delivered to and accepted by it as provided in this subsection 10.1B(ii).

          C. Participations. Each Participant, other than any Participant that is an Affiliate of the Lender granting such participation, shall not be entitled to require such Lender to take or omit to take any action hereunder except action directly affecting (i) the extension of the scheduled final maturity date of any Loan or Commitment allocated to such participation, (ii) a reduction of the principal amount of, the rate of interest payable or the fees payable on any Loan or Commitment allocated to such participation or (iii) a release of all or substantially all the value of the Subsidiary Guaranty, in each case other than in accordance with the terms of the Loan Documents, and all amounts payable by Company hereunder (including amounts payable to such Lender pursuant to subsections 2.6D and 2.7) shall be determined as if such Lender had not sold such participation. Company and each Lender hereby acknowledge and agree that, solely for purposes of subsections 10.4 and 10.5, (a) any participation will give rise to a direct obligation of Company to the Participant and (b) the Participant shall be considered to be a “Lender”.

          D. Pledges of Obligations. In addition to the assignments and participations permitted under the foregoing provisions of this subsection 10.1, any Lender may assign and pledge all or any portion of its Loans, the other Obligations owed to such Lender, and its Notes to secure obligations of such Lender including without limitation any assignment or pledge to a Federal Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any operating circular issued by such Federal Reserve Bank; provided that (i) no Lender shall, as between Company and such Lender, be relieved of any of its obligations hereunder as a result of any such assignment and pledge and (ii) in no event shall such Federal Reserve Bank be considered to be a “Lender” or be entitled to require the assigning Lender to take or omit to take any action hereunder.

          E. Assignments to Special Purpose Funding Vehicles. In addition to the assignments and participations permitted under the foregoing provisions of this subsection 10.1, any Lender (a “Granting Lender”) may grant to special purpose funding vehicle (an “SPV”), identified as such in writing from time to time by the Granting Lender to Administrative Agent and Company, the option to provide to Company all or any part of any Loan that such Granting Lender would otherwise be obligated to make Company pursuant to this Agreement; provided, (i) nothing herein shall constitute a commitment by any SPV to make any Loan and (ii) if an SPV elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPV hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees that no SPV shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPV, it will not institute against, or join any other person in instituting against, such SPV, any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this subsection 10.1E(i), any SPV may (i) with notice to, but without the prior written consent of, Company and Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loan to the Granting Lender or to any financial institutions (consented to by Administrative Agent) providing liquidity and/or credit support to or for the account of such SPV to support the funding or maintenance of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit liquidity enhancement to such SPV.

Each Lender that becomes a party hereto pursuant to an Assignment Agreement shall be deemed to agree that the representations and warranties of such Lender contained in Section 2(c) of such Assignment Agreement are incorporated herein by this reference.

          10.2 Expenses

          10.3 Indemnity

          In addition to the payment of expenses pursuant to subsection 10.2, whether or not the transactions contemplated hereby shall be consummated, Company agrees to defend (subject to Indemnitees’ selection of counsel), indemnify, pay and hold harmless Agents and Lenders, and the officers, directors, employees, trustee, agents and affiliates of Agents and Lenders (collectively called the “Indemnitees”), from and against any and all Indemnified Liabilities (as hereinafter defined); provided that Company shall not have any obligation to any Indemnitee hereunder with respect to any Indemnified Liabilities to the extent such Indemnified Liabilities arise solely from the gross negligence or willful misconduct of that Indemnitee as determined by a final judgment of a court of competent jurisdiction.

          To the extent that the undertakings to defend, indemnify, pay and hold harmless set forth in this subsection 10.3 may be unenforceable in whole or in part because they are violative of any law or public policy, Company shall contribute the maximum portion that it is permitted to pay and satisfy under applicable law to the payment and satisfaction of all Indemnified Liabilities incurred by Indemnitees or any of them.

          10.4 Set-Off

          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 is hereby authorized by Company at any time or from time to time, without notice to Company or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and to apply any and all deposits (general or special, including Indebtedness evidenced by certificates of deposit, whether matured or unmatured, but not including trust accounts) and any other Indebtedness at any time held or owing by that Lender to or for the credit or the account of Company against and on account of the obligations and liabilities of Company to that Lender under this Agreement and the other Loan Documents, including all claims of any nature or description arising out of or connected with this Agreement or any other Loan Document, provided that said obligations and liabilities shall then be due and payable (whether by acceleration or otherwise).

          10.5 Ratable Sharing

          Lenders hereby agree among themselves that if any of them shall, whether by voluntary payment (other than a voluntary prepayment of Loans made and applied in accordance with the terms of this Agreement), by realization upon security, through the exercise of any right of set-off or banker’s lien, by counterclaim or cross action or by the enforcement of any right under the Loan Documents or otherwise, or as adequate protection of a deposit treated as cash collateral under the Bankruptcy Code, receive payment or reduction of a proportion of the

aggregate amount of principal, interest, amounts payable in respect of fees and other amounts owing to that Lender hereunder or under the other Loan Documents (collectively, the “Aggregate Amounts Owing” to such Lender) which is greater than the proportion received by any other Lender in respect of the Aggregate Amounts Owing to such other Lender, then the Lender receiving such proportionately greater payment shall (i) notify Administrative Agent and each other Lender of the receipt of such payment and (ii) apply a portion of such payment to purchase participations (which it shall be deemed to have purchased from each seller of a participation simultaneously upon the receipt by such seller of its portion of such payment) in the Aggregate Amounts Owing to the other Lenders so that all such recoveries of Aggregate Amounts Owing shall be shared by all Lenders in proportion to the Aggregate Amounts Owing to them; provided that if all or part of such proportionately greater payment received by such purchasing Lender is thereafter recovered from such Lender upon the bankruptcy or reorganization of Company or otherwise, those purchases shall be rescinded and the purchase prices paid for such participations shall be returned to such purchasing Lender ratably to the extent of such recovery, but without interest. Company expressly consents to the foregoing arrangement and agrees that any holder of a participation so purchased may exercise any and all rights of banker’s lien, set-off or counterclaim with respect to any and all monies owing by Company to that holder with respect thereto as fully as if that holder were owed the amount of the participation held by that holder.

          10.6 Amendments and Waivers

          A. No amendment, modification, termination or waiver of any provision of this Agreement or of the Notes, and no consent to any departure by Company therefrom, shall in any event be effective without the written concurrence of Requisite Lenders; provided that no amendment, modification, termination, waiver or consent shall, without the written consent of each Lender directly and adversely affected thereby, (i) reduce the principal amount of any of the Loans; (ii) postpone the scheduled final maturity date of any of the Loans or the date on which any interest or any fees are payable; (iii) decrease the interest rate borne by any of the Loans (other than any waiver of any increase in the interest rate applicable to any of the Loans pursuant to subsection 2.2E or any waiver or amendment to Section 7.4) or the amount of any fees payable to the Lenders hereunder; or (iv) increase the maximum duration of Interest Periods permitted hereunder; provided, further, that no such amendment, modification, termination, waiver or consent shall (i) increase the Commitments of a Lender over the amount hereof then in effect, or extend the period of availability of the Commitment of a Lender beyond the expiration date of its Commitment as provided by subsection 2.1A, without the consent of such Lender, (ii) change in any manner the definition of “Requisite Lenders” or the definition of “Pro Rata Share” without the written consent of each Lender, (iii) change in any manner any provision of this Agreement which, by its terms, expressly requires the approval or concurrence of all Lenders without the written consent of each Lender, (iv) release all or substantially all the value of the Subsidiary Guaranty, in each case other than in accordance with the terms of the Loan Documents, without the written consent of each Lender or (v) change in any manner the provisions contained in subsection 8.1 or this subsection 10.6 without the written consent of each Lender. In addition, (i) no amendment, modification, termination or waiver of any provision of any Note shall be effective without the written concurrence of the Lender which is the holder of that Note and (ii) no amendment, modification, termination or waiver of any provision of Section

9 or of any other provision of this Agreement which, by its terms, expressly requires the approval or concurrence of Administrative Agent shall be effective without the written concurrence of Administrative Agent. Administrative Agent may, but shall have no obligation to, with the concurrence of any Lender, execute amendments, modifications, waivers or consents on behalf of that Lender. Any waiver or consent shall be effective only in the specific instance and for the specific purpose for which it was given. No notice to or demand on Company in any case shall entitle Company to any other or further notice or demand in similar or other circumstances. Any amendment, modification, termination, waiver or consent effected in accordance with this subsection 10.6 shall be binding upon each Lender at the time outstanding, each future Lender and, if signed by Company, on Company.

          B. Replacement of Lender. If, in connection with any proposed change, waiver, discharge or termination to any of the provisions of this Agreement that requires the consent of each Lender or each Lender affected thereby, the consent of the Requisite Lenders is obtained but the consent of one or more of such other Lenders whose consent is required is not obtained, then Administrative Agent shall have the right with the consent of Company, so long as all non-consenting Lenders whose individual consent is required are treated as described in either clause (A) or (B) below, to either (A) replace each such non-consenting Lender or Lenders with one or more Replacement Lenders pursuant to subsection 2.8 so long as at the time of such replacement each outstanding Loan of each such Lender being replaced is repaid in full (including accrued and unpaid interest or any fees or other amounts then due and payable) and so long as each such Replacement Lender consents to the proposed change, waiver, discharge or termination or (B) terminate such non-consenting Lender’s Commitments and/or repay in full each outstanding Loan of such Lender, provided that, unless the Commitments that are terminated, and Loans repaid, pursuant to preceding clause (B) are immediately replaced in full at such time through the addition of new Lenders or the increase of the Commitments and/or outstanding Loans of existing Lenders (who in each case must specifically consent thereto), then in the case of any action pursuant to preceding clause (B) the Requisite Lenders (determined after giving effect to the proposed action) shall specifically consent thereto; provided, further, that in any event Administrative Agent shall not have the right to replace a Lender, terminate its Commitments or repay its Loans solely as a result of the exercise of such Lender’s rights (and the withholding of any required consent by such Lender) to refuse to increase its Commitment over the amount then in effect pursuant to the second proviso contained in the first sentence of subsection 10.6A.

          10.7 Independence of Covenants

          All covenants hereunder shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or would otherwise be within the limitations of, another covenant shall not avoid the occurrence of an Event of Default or Potential Event of Default if such action is taken or condition exists.

          10.8 Notices

          Unless otherwise specifically provided herein, any notice or other communication herein required or permitted to be given shall be in writing and may be personally served or sent by telefacsimile or United States mail or courier service and shall be deemed to have been given when delivered in person or by courier service, upon receipt of telefacsimile, or three Business Days after depositing it in the United States mail with postage prepaid and properly addressed; provided that notices to Agents shall not be effective until received; provided further, that Administrative Agent may make all notices, requests, financial statements, financial and other reports, certificates and other information materials, but excluding any such communication that (i) is or relates to a borrowing request or a conversion/continuation notice, (ii) relates to the payment of any principal or other amount due under this Agreement prior to the scheduled date therefor, (iii) provides notice of any Potential Event of Default or Event of Default under this Agreement or any other Loan Document or (iv) is required to be delivered to satisfy any condition precedent to the effectiveness of this Agreement and/or the Borrowing (all such non-excluded communications being referred to herein collectively as “Communications”) available to the Lenders by posting the Communications on Intralinks or a substantially similar electronic transmission system. For the purposes hereof, the address of each party hereto shall be as set forth under such party’s name on the signature pages hereof or (i) as to Company and Administrative Agent, such other address as shall be designated by such Person in a written notice delivered to the other parties hereto and (ii) as to each other party, such other address as shall be designated by such party in a written notice delivered to Administrative Agent.

          10.9 Survival of Representations, Warranties and Agreements

          A. All representations, warranties and agreements made herein shall survive the execution and delivery of this Agreement and the making of the Loans.

          B. Notwithstanding anything in this Agreement or implied by law to the contrary, the agreements of Company set forth in subsections 2.6D, 2.7, 10.2, 10.3 and 10.4 and the agreements of Lenders set forth in subsections 9.2C, 9.4 and 10.5 shall to the extent set forth therein survive the payment of the Loans and the termination of this Agreement.

          10.10 Failure or Indulgence Not Waiver; Remedies Cumulative

          No failure or delay on the part of Administrative Agent or any Lender in the exercise of any power, right or privilege hereunder or under any other Loan Document shall impair such power, right or privilege or be construed to be a waiver of any default or acquiescence therein, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other power, right or privilege. All rights and remedies existing under this Agreement and the other Loan Documents are cumulative to, and not exclusive of, any rights or remedies otherwise available.

          10.11 Marshalling; Payments Set Aside

          Neither Administrative Agent nor any Lender shall be under any obligation to marshal any assets in favor of Company or any other party or against or in payment of any or all of the Obligations. To the extent that Company makes a payment or payments to Administrative Agent or Lenders (or to Administrative Agent for the benefit of Lenders), or Administrative Agent or Lenders enforce any security interests or exercise their rights of set-off, and such payment or payments or the proceeds of such enforcement or set-off 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, any other state or federal law, common law or any equitable cause, then, to the extent of such recovery, the obligation or part thereof originally intended to be satisfied, and all Liens, rights and remedies therefor or related thereto, shall be revived and continued in full force and effect as if such payment or payments had not been made or such enforcement or setoff had not occurred.

          10.12 Severability

          In case any provision in or obligation under this Agreement or the Notes shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby.

          10.13 Obligations Several; Independent Nature of Lenders’ Rights

          The obligations of Lenders hereunder are several and no Lender shall be responsible for the obligations or Commitments of any other Lender hereunder. Nothing contained herein or in any other Loan Document, and no action taken by Lenders pursuant hereto or thereto, shall be deemed to constitute Lenders as a partnership, an association, a joint venture or any other kind of entity. The amounts payable at any time hereunder to each Lender shall be a separate and independent debt, and each Lender shall be entitled to protect and enforce its rights arising out of this Agreement and it shall not be necessary for any other Lender to be joined as an additional party in any proceeding for such purpose.

          10.14 Headings

          Section and subsection headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose or be given any substantive effect.

Neither Company’s rights or obligations hereunder nor any interest therein may be assigned or delegated by Company without the prior written consent of all Lenders.

          10.17 CONSENT TO JURISDICTION AND SERVICE OF PROCESS

          ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST COMPANY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY OBLIGATIONS THEREUNDER, MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN THE STATE, COUNTY AND CITY OF NEW YORK.

               (iv) AGREES THAT SERVICE AS PROVIDED IN CLAUSE (iii) ABOVE IS SUFFICIENT TO CONFER PERSONAL JURISDICTION OVER COMPANY IN ANY SUCH PROCEEDING IN ANY SUCH COURT, AND OTHERWISE CONSTITUTES EFFECTIVE AND BINDING SERVICE IN EVERY RESPECT;

               (v) AGREES THAT LENDERS RETAIN THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO BRING PROCEEDINGS AGAINST COMPANY IN THE COURTS OF ANY OTHER JURISDICTION; AND

The scope of this waiver is intended to be all-encompassing of any and all disputes that may be filed in any court and that relate to the subject matter of this transaction, including contract claims, tort claims, breach of duty claims and all other common law and statutory claims. Each party hereto acknowledges that this waiver is a material inducement to enter into a business relationship, that each has already relied on this waiver in entering into this Agreement, and that each will continue to rely on this waiver in their related future dealings. Each party hereto further warrants and represents that it has reviewed this waiver with its legal counsel and that it knowingly and voluntarily waives its jury trial rights following consultation with legal counsel.

In the event of litigation, this Agreement may be filed as a written consent to a trial by the court.

          Each Lender shall hold all non-public information obtained pursuant to the requirements of this Agreement which has been identified as confidential by Company in accordance with such Lender’s customary procedures for handling confidential information of this nature and in accordance with safe and sound banking practices, if applicable, it being understood and agreed by Company that in any event a Lender may make disclosures to the

accountants, auditors, attorneys, and Affiliates of such Lender or disclosures reasonably required by any bona fide assignee, transferee or participant or to any actual or prospective contractual counterparty (or its advisor) to any securitization, hedge or other derivative transaction in connection with the contemplated assignment or transfer by such Lender of any Loans or any participations therein or disclosures required or requested by any governmental agency or representative thereof or pursuant to legal process; provided that, in each of the foregoing cases, the Person to which disclosure is to be made is informed of the confidential nature of such information and agrees to maintain its confidentiality; provided, further, that, unless specifically prohibited by applicable law or court order, each Lender shall notify Company of any request by any governmental agency or representative thereof (other than any such request in connection with any routine compliance examination or examination of the financial condition of such Lender by such governmental agency) for disclosure of any such non-public information prior to disclosure of such information; and provided, further, that in no event shall any Lender be obligated or required to return any materials furnished by Company or any of its Subsidiaries. Any Person required to maintain the confidentiality of information as provided in this subsection shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such information as such person would accord to its own confidential information.
