The Company hereby requests that the aggregate commitments available under the Original Credit Agreement be increased, that certain additional amendments be made to the Original Credit Agreement and, for the sake of clarity and convenience, that the Original Credit Agreement be restated in its entirety as so amended. This Second Amended and Restated Credit Agreement amends and replaces in its entirety the Original Credit Agreement, and from the Effective Date all references made to the Original Credit Agreement in any Loan Document or in any other instrument or document shall, without more, be deemed to refer to this Second Amended and Restated Credit Agreement. This Second Amended and Restated Credit Agreement shall become effective as of May 18, 1998 (the "Effective Date"), and supersedes all provisions of the Original Credit Agreement as of such date, upon the execution of this Second Amended and Restated Credit Agreement by each of the parties hereto and the fulfillment of the conditions precedent contained in Section 6.2 hereof. SECTION 1. THE CREDITS. Section 1.1. Revolving Credit. Subject to the terms and conditions hereof, each Lender, by its acceptance hereof, severally agrees to extend a revolving credit (the "Revolving Credit") to the Company in the aggregate amount of such Lender's commitment to extend the Revolving Credit as set forth on the applicable signature page hereof or pursuant to Section 11.18 hereof (its "Revolving Credit Commitment" and cumulatively for all Lenders the "Revolving Credit Commitments") (subject to any reductions thereof pursuant to the terms hereof) prior to the Termination Date. The Revolving Credit, subject to all of the terms and conditions hereof, may be utilized by the Company in the form of Revolving Loans and Letters of Credit, all as more fully hereinafter set forth; provided, however, that the aggregate principal amount of the Revolving Loans and L/C Obligations outstanding at any one time shall not at any time exceed the lesser of (i) the Revolving Credit Commitments then in effect and (ii) the Borrowing Base as then determined and computed. During the period from and including the date thereof to but not including the Termination Date, the Company may use the Revolving Credit Commitments by borrowing, repaying and reborrowing Revolving Loans in whole or in part and/or by having the Agent issue Letters of Credit, having such Letters of Credit expire or otherwise terminate without having been drawn upon or, if drawn upon, reimbursing the Agent for each such drawing, and having the Agent issue new Letters of Credit, all in accordance with the terms and conditions of this Agreement. For all purposes of this Agreement, where a determination of the unused or available amount of the Revolving Credit Commitments is necessary, the Revolving Loans and L/C Obligations shall all be deemed to utilize the Revolving Credit Commitments. The obligations of the Lenders hereunder are several and not joint, and no Lender shall under any circumstances be obligated to extend credit hereunder in excess of its Revolving Credit Commitment. Section 1.2. Revolving Loans. Subject to the terms and conditions hereof, the Revolving Credit may be availed of in the form of loans (individually a "Revolving Loan" and collectively the "Revolving Loans"). Each Borrowing of Revolving Loans shall be made ratably by the Lenders in accordance with their Percentages. Each Borrowing of Revolving Loans shall be in an amount of $50,000 or such greater amount which is an integral multiple of $50,000; provided, however, that (i) a Borrowing made to repay a Reimbursement Obligation may be made in the amount thereof and (ii) a Borrowing of Revolving Loans, or any part thereof, which bears interest with reference to the Adjusted LIBOR Rate shall be in such greater amount as is required by Section 2 hereof. All Revolving Loans made by a Lender shall be evidenced by a single Revolving Credit Note of the Company (individually a "Revolving Credit Note" and collectively the "Revolving Credit Notes", which shall include the Revolving Credit Notes issued pursuant to Section 11.18 hereof) payable to the order of such Lender in the amount of its Revolving Credit Commitment, each Revolving Credit Note to be in the form (with appropriate insertions) attached hereto as Exhibit A. Each Revolving Credit Note shall be dated the date of issuance thereof, be expressed to bear interest as set forth in Section 2 hereof, and be expressed to mature on the Termination Date. Without regard to the principal amount of each Revolving Credit Note stated on its face, the actual principal amount at any time outstanding and owing by the Company on account thereof shall be the sum of all Revolving Loans then or theretofore made thereon less all payments of principal actually received thereon. Section 1.3. Letters of Credit. (a) General Terms. Subject to the terms and conditions hereof, as part of the Revolving Credit, the Agent shall issue standby letters of credit (each a "Letter of Credit") for the account of the Company in U.S. Dollars in an aggregate undrawn face amount up to the amount of the L/C Commitment. Each Letter of Credit shall be issued by the Agent, but each Lender shall be obligated to reimburse the Agent for such Lender's Percentage of the amount of each draft drawn under a Letter of Credit and, accordingly, each Letter of Credit shall be deemed to utilize the Revolving Credit Commitment of each Lender pro rata in accordance with its Percentage thereof. (b) Applications. At any time before the Termination Date, the Agent shall, at the request of the Company, issue one or more Letters of Credit to or for the account of the Company in a form satisfactory to the Agent, with expiration dates no later than 12 months from the date of issuance (or be cancelable not later than 12 months from the date of issuance and each renewal), in an aggregate face amount as set forth above, upon the receipt -2- of an application for the relevant Letter of Credit in the form then customarily prescribed by the Agent duly executed by the Company (each an "Application"). For purposes of this Agreement and the other Loan Documents, Harris Trust and Savings Bank Standby Letter of Credit SPL no. 33769 issued for the account of WSKC Dialysis Services, Inc. (f/k/a West Suburban Kidney Center, S.C.) in favor of BankAmerica Trust & Banking Corporation (Cayman) Limited shall be deemed a Letter of Credit issued under this Agreement, and the Company agrees that from and after the date of this Agreement the Company shall be jointly and severally liable with WSKC Dialysis Services, Inc. for all obligations owing to Harris Trust and Savings Bank with respect to such Letter of Credit, including all reimbursement obligations arising under or relating to that certain Application and Agreement for Irrevocable Standby Letter of Credit dated December 8, 1989, as amended, with respect thereto (which agreement shall be deemed an Application for all purposes of this Agreement and the other Loan Documents). On the Termination Date, the Company shall pay to the Agent an amount equal to the aggregate amounts undrawn on all Letters of Credit which are outstanding on that date to be held as cash collateral for the Obligations of the Company with respect to such Letters of Credit. Notwithstanding anything contained in any Application to the contrary, (i) the obligation of the Company to pay fees in connection with each Letter of Credit shall be as set forth in Section 3.3 hereof and (ii) except during the existence of an Event of Default, the Agent will not call for the funding by the Company of any amount under a Letter of Credit, or any other form of collateral security for the obligations of the Company in connection with such Letter of Credit, before being presented with a drawing thereunder other than the collateral security contemplated by this Agreement and the Collateral Documents. The Agent will promptly notify the Lenders of each issuance by the Agent of a Letter of Credit. If the Agent issues any Letter of Credit with an expiration date that is automatically extended unless the Agent gives notice that the expiration date will not so extend beyond its then scheduled expiration date, the Agent will give such notice of non- renewal before the time necessary to prevent such automatic extension if, before such required notice date, (i) the expiration date of such Letter of Credit if so extended would be after the Termination Date, (ii) the Revolving Credit Commitments have been terminated or (iii) a Default or an Event of Default has occurred and is continuing and the Required Lenders have given the Agent instructions not to so permit the extension of the expiration date of such Letter of Credit. The Agent agrees to issue amendments to the Letter(s) of Credit increasing the amount, or extending the expiration date, thereof at the request of the Company subject to the conditions of Section 6 and the other terms of this Section 1.3. Without limiting the generality of the foregoing, the Agent will not issue, amend or extend the expiration date of any Letter of Credit if any Lender notifies the Agent of any failure to satisfy or otherwise comply with the conditions and terms of Section 6 and of this Section 1.3 and directs the Agent not to take such action. (c) The Reimbursement Obligation. Subject to Section 1.3(b) hereof, the obligation of the Company to reimburse the Agent for all drawings under a Letter of Credit (a "Reimbursement Obligation") shall be governed by the Application related to such Letter of Credit, except that (i) reimbursement of each drawing shall be made in immediately available funds at the Agent's principal office in Chicago, Illinois by no later than 12:00 noon Chicago time on the date when such drawing is paid if the Company has been informed of such drawing by the Agent on or before 11:30 a.m. Chicago time on the date when such -3- drawing is paid or, if notice of such drawing is given to Company after 11:30 a.m. Chicago time on the date when such drawn is paid, by the end of such day and (ii) the Company's Reimbursement Obligation shall bear interest (which the Company hereby promises to pay), whether before or after judgment, until payment in full thereof at the rate per annum equal to 2% plus the Applicable Margin for Revolving Loans plus the Domestic Rate as in effect from time to time. If the Company does not make any such reimbursement payment on the date due and the Participating Lenders fund their participations therein in the manner set forth in Section 1.3(d) below, then all payments thereafter received by the Agent in discharge of any of the relevant Reimbursement Obligations shall be distributed in accordance with Section 1.3(d) below. (d) The Participating Interests. Each Lender (other than the Lender then acting as Agent in issuing Letters of Credit), by its acceptance hereof, severally agrees to purchase from the Agent, and the Agent hereby agrees to sell to each such Lender (a "Participating Lender"), an undivided percentage participating interest (a "Participating Interest"), to the extent of its Percentage, in each Letter of Credit issued by, and each Reimbursement Obligation owed to, the Agent. Upon any failure by the Company to pay any Reimbursement Obligation in respect of a Letter of Credit at the time required on the date the related drawing is paid, as set forth in Section 1.3(c) above, or if the Agent is required at any time to return to the Company or to a trustee, receiver, liquidator, custodian or other Person any portion of any payment of any Reimbursement Obligation, each Participating Lender shall, not later than the Business Day it receives a certificate in the form of Exhibit B hereto from the Agent to such effect, if such certificate is received before 2:00 p.m. Chicago time, or not later than the following Business Day, if such certificate is received after such time, pay to the Agent an amount equal to such Lender's Percentage of such unpaid or recaptured Reimbursement Obligation together with interest on such amount accrued from the date the related payment was made by the Agent to the date of such payment by such Participating Lender at a rate per annum equal to (i) from the date the related payment was made by the Agent to the date 2 Business Days after payment by such Participating Lender is due hereunder, the Federal Funds Rate for each such day and (ii) from the date 2 Business Days after the date such payment is due from such Participating Lender to the date such payment is made by such Participating Lender, the Domestic Rate in effect for each such day. Each such Participating Lender shall thereafter be entitled to receive its Percentage of each payment received in respect of the relevant Reimbursement Obligation and of interest paid thereon, with the Agent retaining its Percentage as a Lender hereunder. The several obligations of the Participating Lenders to the Agent under this Section 1.3 shall be absolute, irrevocable and unconditional under any and all circumstances whatsoever and shall not be subject to any set-off, counterclaim or defense to payment which any Participating Lender may have or have had against the Company, the Agent, any other Lender or any other Person whatsoever. Without limiting the generality of the foregoing, such obligations shall not be affected by any Default or Event of Default or by any reduction or termination of any Revolving Credit Commitment of any Lender, and each payment by a Participating Lender under this Section 1.3 shall be made without any offset, abatement, withholding or reduction whatsoever. The Agent shall be entitled to offset amounts received -4- for the account of a Lender under this Agreement against unpaid amounts due from such Lender to the Agent hereunder (whether as fundings of participations, indemnities or otherwise), but shall not be entitled to offset against amounts owed to the Agent by any Lender arising outside this Agreement. (e) Indemnification. The Participating Lenders shall, to the extent of their respective Percentages, indemnify the Agent (to the extent not reimbursed by the Company) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from the Agent's gross negligence or willful misconduct) that the Agent may suffer or incur in connection with any Letter of Credit. The obligations of the Participating Lenders under this Section 1.3(e) and all other parts of this Section 1.3 shall survive termination of this Agreement, the Applications, and all drafts and any other documents presented in connection with a drawing under any Letter of Credit. Section 1.4. Acquisition Financing Credit. (a) Subject to the terms and conditions hereof, each Lender severally agrees to make on or after the date of this Agreement one or more loans (individually an "Acquisition Financing Loan" and collectively the "Acquisition Financing Loans") to the Company in the aggregate amount of such Lender's commitment to make its Acquisition Financing Loans as set forth on the applicable signature page hereof or pursuant to Section 11.18 hereof (its "Acquisition Financing Commitment" and cumulatively for all Lenders the "Acquisition Financing Commitments") (subject to increases thereof pursuant to Section 1.7 hereof and to any reductions thereof pursuant to the terms hereof) prior to the Acquisition Financing Termination Date. Each Borrowing of Acquisition Financing Loans shall be made ratably by the Lenders in accordance with their Percentages. Each Borrowing of Acquisition Financing Loans shall be in an amount of $250,000 or such greater amount which is an integral multiple of $100,000; provided, however, that a Borrowing of Acquisition Financing Loans, or any part thereof, which bears interest with reference to the Adjusted LIBOR Rate shall be in such greater amount as is required by Section 2 hereof. The principal amount of each Acquisition Financing Loan shall permanently reduce the amount available to the Company under each Lender's Acquisition Financing Commitment, and no amount repaid or prepaid on any Acquisition Financing Loan may be borrowed again. The proceeds of each Acquisition Financing Loan shall be used solely for the purposes set forth in Section 5.4(d) hereof. All Acquisition Financing Loans made by a Lender to the Company shall initially be evidenced by a single Acquisition Financing Note of Company (individually an "Acquisition Financing Note" and collectively the "Acquisition Financing Notes", which shall include the Acquisition Financing Notes issued pursuant to Section 11.18 hereof) payable to the order of such Lender in the amount of its Acquisition Financing Commitment, each Acquisition Financing Note to be in the form (with appropriate insertions) attached hereto as Exhibit C. Each Acquisition Financing Note shall be dated the date of issuance thereof, be expressed to bear interest as set forth in Section 2 hereof, and be expressed to mature on the Acquisition Financing Termination Date. Without regard to the principal amount of each Acquisition Financing Note stated on its face, the actual principal amount at any time outstanding and owing by the Company on account thereof shall be the sum of all Acquisition Financing Loans then or theretofore made thereon less all payments of principal actually received -5- thereon and all amounts refinanced and evidenced by a Term Note as provided in Section 1.4(b) below. The obligations of the Lenders hereunder are several and not joint, and no Lender shall under any circumstances be obligated to extend credit hereunder in excess of its Acquisition Financing Commitment. (b) Subject to the terms and conditions hereof, the Company shall have the option on or prior to the Acquisition Financing Termination Date to convert all or any part of the outstanding Acquisition Financing Loans into one or more term loans (individually a "Term Loan" and collectively the "Term Loans"). Each Borrowing of Term Loans shall be made ratably by the Lenders in accordance with their Percentages of the outstanding Acquisition Financing Loans being converted. Each Borrowing of Term Loans shall be in an amount of $5,000,000 or such greater amount which is an integral multiple of $1,000,000; provided, however, that (i) a Borrowing made in connection with the conversion of all then outstanding Acquisition Financing Loans and which is accompanied by the termination in whole of the Acquisition Financing Commitments may be made in the amount of the outstanding Acquisition Financing Loans being so converted and (ii) a Borrowing of Term Loans, or any part thereof, which bears interest with reference to the Adjusted LIBOR Rate shall be in such greater amount as is required by Section 2 hereof. Each Term Loan made by a Lender shall be evidenced by a Term Note of the Company (individually a "Term Note" and collectively the "Term Notes", which shall include the Term Notes issued pursuant to Section 11.18 hereof) payable to the order of such Lender in an amount equal to such Lender's Percentage of the Acquisition Financing Loans converted, each Term Note to be in the form (with appropriate insertions) attached hereto as Exhibit D. Each Term Note shall be dated the date of issuance thereof, be expressed to bear interest as set forth in Section 2 hereof, and be expressed to mature in 20 consecutive quarterly principal installments, with the first 19 principal installments of a Term Note to be in an amount equal to 1/28th of the original principal amount of the Term Loan evidenced thereby, commencing on the date which is three calendar months after the date on which the relevant Acquisition Financing Loans are converted into such Term Loan and continuing on the same date of each and every third calendar month thereafter (or if no such date exists for any one or more of such installments, then on the last day of such third calendar month), with a final payment of both principal and interest not sooner paid due on the fifth anniversary date of the date on which the relevant Acquisition Financing Loans were converted into the relevant Borrowing of Term Loans. The principal amount of each Term Loan made by Lender hereunder shall concurrently reduce by like amount the amount outstanding under its Acquisition Financing Note, and no amount repaid or prepaid on any Term Loan may be borrowed again. Any Acquisition Financing Loans which are not converted into Term Loans pursuant to this Section 1.4(b) shall be due and payable on the Acquisition Financing Termination Date. Section 1.5. Supplemental Revolving Credit. (a) Subject to the terms and conditions hereof, and only for so long as the Acquisition Financing Commitments remain outstanding, each Lender, by its acceptance hereof, severally agrees to extend a supplemental revolving credit (the "Supplemental Revolving Credit") to the Company in the aggregate amount of such Lender's commitment to extend the Supplemental Revolving Credit as set forth on the applicable signature page hereof or pursuant to Section 11.18 hereof (its "Supplemental Revolving Credit Commitment" and cumulatively for all Lenders the "Supplemental -6- Revolving Credit Commitments") (subject to any reductions thereof pursuant to the terms hereof) prior to the Supplemental Revolving Credit Termination Date. The Supplemental Revolving Credit, subject to all of the terms and conditions hereof, may be utilized by the Company in the form of loans (individually a "Supplemental Revolving Loan" and collectively the "Supplemental Revolving Loans"), all as more fully hereinafter set forth; provided, however, that: (i) the aggregate principal amount of the Supplemental Revolving Loans outstanding at any one time shall not at any time exceed the difference between (x) the Supplemental Revolving Credit Commitments then in effect minus (y) the aggregate amount of loans and advances made by the Company or any Restricted Subsidiary to, and guarantees made by the Company or any Restricted Subsidiary in respect of the obligations of, any Person (other than Restricted Subsidiaries) in which the Company, directly or indirectly, holds an equity interest in (determined in accordance with Section 7.15 hereof, but determined exclusive of any such loans or advances financed with the proceeds of a Supplemental Revolving Loan); and (ii) the sum of the aggregate principal amount of the Supplemental Revolving Loans at any one time outstanding plus the original principal amount of all Acquisition Financing Loans made hereunder (without regard to any subsequent payments of principal thereon) shall not at any time exceed the difference of (i) $65,000,000 plus any portion (up to $5,000,000) of the Revolving Credit Commitments converted into Acquisition Financing Commitments pursuant to Section 1.7 hereof minus (ii) all amounts of the Acquisition Financing Commitments voluntarily terminated pursuant to Section 3.8 hereof. The proceeds of each Supplemental Revolving Loan shall be used solely for the purposes set forth in Section 5.4(b) hereof. During the period from and including the date thereof to but not including the Supplemental Revolving Credit Termination Date, the Company may use the Supplemental Revolving Credit Commitments by borrowing, repaying and reborrowing Supplemental Revolving Loans in whole or in part, all in accordance with the terms and conditions of this Agreement. (b) Each Borrowing of Supplemental Revolving Loans shall be made ratably by the Lenders in accordance with their Percentages. Each Borrowing of Supplemental Revolving Loans shall be in an amount of $50,000 or such greater amount which is an integral multiple of $50,000; provided, however, that a Borrowing of Supplemental Revolving Loans, or any part thereof, which bears interest with reference to the Adjusted LIBOR Rate shall be in such greater amount as is required by Section 2 hereof. All Supplemental Revolving Loans made by a Lender shall be evidenced by a single Supplemental Revolving Credit Note of the Company (individually a "Supplemental Revolving Credit Note" and collectively the "Supplemental Revolving Credit Notes", which shall include the Supplemental Revolving Credit Notes issued pursuant to Section 11.18 hereof) payable to the order of such Lender in the amount of its Supplemental Revolving Credit Commitment, each Supplemental Revolving Credit Note to be in the form (with appropriate insertions) attached hereto as Exhibit E. Each Supplemental Revolving Credit Note shall be dated the date of issuance thereof, be -7- expressed to bear interest as set forth in Section 2 hereof, and be expressed to mature on the Supplemental Revolving Credit Termination Date. Without regard to the principal amount of each Supplemental Revolving Credit Note stated on its face, the actual principal amount at any time outstanding and owing by the Company on account thereof shall be the sum of all Supplemental Revolving Loans then or theretofore made thereon less all payments of principal actually received thereon. The obligations of the Lenders hereunder are several and not joint, and no Lender shall under any circumstances be obligated to extend credit hereunder in excess of its Supplemental Revolving Credit Commitment. Section 1.6. Manner of Borrowing Loans. (a) Generally. The Company shall give the Agent notice (which may be written or oral, but if oral, promptly confirmed in writing, including notice by telecopy) by 10:00 a.m. Chicago time on any Business Day of each request for any Borrowing of Loans, in each case specifying the amount of each such Borrowing, the type of Loan being requested, and the date such Borrowing is to be made (which shall be a Business Day). The Agent shall notify each Lender of its receipt of each such notice by 12:00 noon Chicago time on the Business Day any Borrowing of Loans constituting the Domestic Rate Portion is to be made and by 12:00 noon Chicago time on the Business Day it receives such a request for any Borrowing of Loans constituting a LIBOR Portion. Each Borrowing shall initially constitute part of the relevant Domestic Rate Portion except to the extent the Company has timely elected that such Borrowing, or any part thereof, constitute part of a LIBOR Portion as provided in Section 2 hereof. Not later than 2:00 p.m. Chicago time on the date specified for any Borrowing of Loans to be made hereunder, each Lender shall make the proceeds of its Loan comprising part of such Borrowing available in immediately available funds to the Agent in Chicago, Illinois, except in the case of the Term Loans, in which case each Lender shall record the Term Loan made by it as part of the conversion of the Acquisition Financing Loans, or such portion thereof, held by it into such Term Loan on its books and records and shall effect the repayment in whole or in part, as appropriate, of the Acquisition Financing Loans through the proceeds of such Term Loan. Subject to all of the terms and conditions hereof, the proceeds of each Lender's Loan shall be made available to the Company in accordance with the instruction of the Company at the office of the Agent in Chicago, Illinois and in funds there current. (b) Reimbursement Obligation. In the event the Company fails to give notice pursuant to Section 1.6(a) above of a Borrowing equal to the amount of a Reimbursement Obligation and has not notified the Agent by 11:30 a.m. Chicago time on the day such Reimbursement Obligation becomes due that the Company intends to repay such Reimbursement Obligation through funds not borrowed under this Agreement, the Company shall be deemed to have requested a Borrowing of Revolving Loans constituting part of the Domestic Rate Portion on such day in the amount of the Reimbursement Obligation then due, subject to Section 6 hereof, which Borrowing shall be applied to pay the Reimbursement Obligation then due. (c) Agent Reliance on Bank Funding. Unless the Agent shall have been notified by a Lender before the date on which such Lender is scheduled to make payment to the Agent -8- of the proceeds of a Loan (which notice shall be effective upon receipt) that such Lender does not intend to make such payment, the Agent may assume that such Lender has made such payment when due and the Agent may in reliance upon such assumption (but shall not be required to) make available to the Company the proceeds of the Loan to be made by such Lender and, if any Lender has not in fact made such payment to the Agent, such Lender shall, on demand, pay to the Agent the amount made available to the Company attributable to such Lender together with interest thereon in respect of each day during the period commencing on the date such amount was made available to the Company and ending on (but excluding) the date such Lender pays such amount to the Agent at a rate per annum equal to the Federal Funds Rate. If such amount is not received from such Lender by the Agent immediately upon demand, the Company will, on demand, repay to the Agent the proceeds of the Loan attributable to such Lender with interest thereon at a rate per annum equal to the interest rate applicable to the relevant Loan, but without such payment being considered a payment or prepayment of a Loan under Section 2.8 hereof, so that the Company will have no liability under Section 2.8 with respect to such payment. (d) Reliance. All requests for Borrowings and selection of interest rates to be applicable thereto may be written or oral, including by telephone or telecopy. The Company agrees that the Agent may rely on any such notice given by any person the Agent in good faith believes is an Authorized Representative without the necessity of independent investigation (the Company hereby indemnifying the Agent and Lenders from any liability or loss ensuing from such reliance), and in the event any such telephonic or other oral notice conflicts with any written confirmation, such oral or telephonic notice shall govern if the Agent has acted in reliance thereon. Section 1.7. Commitment Conversion Option. At any time prior to the Acquisition Financing Termination Date, the Company shall have the option from time to time to convert up to $5,000,000 of the Revolving Credit Commitments in the aggregate into Acquisition Financing Commitments provided that (a) the Company shall give the Agent and the Lenders not less than five (5) Business Days prior written notice of the Company's exercise of such option, (b) the minimum amount of Revolving Credit Commitments converted at any one time into Acquisition Financing Commitments pursuant hereto shall not be less than $1,000,000 at such time, or such greater amount which is an integral multiple of $1,000,000, (c) the Revolving Credit Commitments shall be permanently reduced by the amount so converted to Acquisition Financing Commitments, which reduction shall be applied ratably among the Lenders in accordance with their Percentages, and (d) after giving effect to the conversion, the Revolving Loans and L/C Obligations then outstanding must not exceed the lesser of the Borrowing Base then outstanding or the Revolving Credit Commitments in effect after giving effect to such conversion. SECTION 2. INTEREST. Section 2.1. Options. Subject to all of the terms and conditions of this Section 2, portions of the principal indebtedness evidenced by the Notes (all of the indebtedness evidenced by Notes of the same type and, with respect to the Term Notes, relating to the same Borrowing, and bearing interest at the same rate for the same period of time being -9- hereinafter referred to as a "Portion") may, at the option of the Company, bear interest with reference to the Domestic Rate ("Domestic Rate Portions") or with reference to the Adjusted LIBOR Rate ("LIBOR Portions"), and Portions may be converted from time to time from one basis to the other. All of the indebtedness evidenced by the Notes of the same type and, with respect to the Term Notes, relating to the same Borrowing, which is not part of a LIBOR Portion shall constitute a single Domestic Rate Portion. All of the indebtedness evidenced by the Notes of the same type and, with respect to the Term Notes, relating to the same Borrowing, which bears interest with reference to a particular Adjusted LIBOR Rate for a particular Interest Period shall constitute a single LIBOR Portion. Anything contained herein to the contrary notwithstanding, there shall not be more than 6 LIBOR Portions applicable to Notes of the same type and, with respect to the Term Notes, relating to the same Borrowing, outstanding at any one time and each Lender shall have a ratable interest in each Portion. The Company hereby promises to pay interest on each Portion applicable to it at the rates and times specified in this Section 2. Section 2.2. Domestic Rate Portion. Each Domestic Rate Portion shall bear interest (which the Company hereby promises to pay at the times herein provided) at the rate per annum determined by adding the Applicable Margin to the Domestic Rate as in effect from time to time, provided that if a Domestic Rate Portion is not paid when due (whether by lapse of time, acceleration or otherwise), such Portion shall bear interest (which the Company hereby promises to pay at the times hereinafter provided), whether before or after judgment, and until payment in full thereof, at the rate per annum determined by adding 2% to the sum of the Applicable Margin plus the Domestic Rate as in effect from time to time. Interest on the Domestic Rate Portions shall be payable on the last day of each March, June, September and December in each year and at maturity of the applicable Notes, and interest after maturity shall be due and payable upon demand. Section 2.3. LIBOR Portions. Each LIBOR Portion shall bear interest (which the Company hereby promises to pay at the times herein provided) for each Interest Period selected therefor at a rate per annum determined by adding the Applicable Margin to the Adjusted LIBOR Rate for such Interest Period, provided that if any LIBOR Portion is not paid when due (whether by lapse of time, acceleration or otherwise), such Portion shall bear interest (which the Company hereby promises to pay at the times hereinafter provided), whether before or after judgment, and until payment in full thereof, through the end of the Interest Period then applicable thereto at the rate per annum determined by adding 2% to the interest rate otherwise applicable thereto and effective at the end of such Interest Period, such LIBOR Portion shall automatically be converted into and added to the applicable Domestic Rate Portion and shall thereafter bear interest at the interest rate applicable to such Domestic Rate Portion after default. Interest on each LIBOR Portion shall be due and payable on the last day of each Interest Period applicable thereto (provided that if any Interest Period is longer than three months, then interest on the LIBOR Portion having such Interest Period shall be due and payable on the date occurring every three months after the date such Interest Period began and on the last day of such Interest Period), and interest after maturity shall be due and payable upon demand. The Company shall notify the Agent on or before 10:00 a.m. Chicago time on the third Business Day preceding the end of an Interest Period applicable to a LIBOR Portion whether such LIBOR Portion is to continue as a -10- LIBOR Portion, in which event the Company shall notify the Agent of the new Interest Period selected therefor, and in the event the Company shall fail to so notify the Agent, such LIBOR Portion shall automatically be converted into and added to the applicable Domestic Rate Portion as of and on the last day of such Interest Period. The Agent shall promptly notify each Lender of each notice received from the Company pursuant to the foregoing provisions. Each LIBOR Portion shall be in an amount equal to $500,000 or such greater amount which is an integral multiple of $100,000. Anything contained herein to the contrary notwithstanding, the obligation of the Lenders to create, continue or effect by conversion any LIBOR Portion shall be conditioned upon the fact that at the time no Default or Event of Default shall have occurred and be continuing. Section 2.4. Manner of Rate Selection. The Company shall notify the Agent by 10:00 a.m. Chicago time at least 3 Business Days prior to the date upon which it requests that any LIBOR Portion be created or that any part of the applicable Domestic Rate Portion be converted into a LIBOR Portion (such notice to specify in each instance the amount thereof and the Interest Period selected therefor) and the Agent shall advise each Lender of each such notice by 12:00 noon Chicago time on the same Business Day it receives such notice. If any request is made to convert a LIBOR Portion into the applicable Domestic Rate Portion, such conversion shall only be made so as to become effective as of the last day of the Interest Period applicable thereto. All requests for the creation, continuance or conversion of Portions under this Agreement shall, subject to Section 2.6 hereof, be irrevocable. Section 2.5. Change of Law. Notwithstanding any other provisions of this Agreement or the Notes, if at any time a Lender shall determine in good faith that any change in applicable laws, treaties or regulations or in the interpretation thereof makes it unlawful for such Lender to create or continue to maintain LIBOR Portions, it shall promptly so notify the Agent (which shall in turn promptly notify the Company and the other Lenders) and the obligation of such Lender to create, continue or maintain any LIBOR Portion under this Agreement shall terminate until it is no longer unlawful for such Lender to create, continue or maintain LIBOR Portions. The Company shall, on demand, if the continued maintenance of a LIBOR Portion is unlawful, thereupon prepay the outstanding principal amount of the LIBOR Portion, together with all interest accrued thereon and all other amounts payable to the affected Lender with respect thereto under this Agreement; provided, however, that the Company may instead elect to convert the principal amount of the affected LIBOR Portion into the applicable Domestic Rate Portion, subject to the terms and conditions of this Agreement. Section 2.6. Unavailability of Deposits or Inability to Ascertain the Adjusted LIBOR Rate. Notwithstanding any other provision of this Agreement or the Notes, if prior to the commencement of any Interest Period, (a) any Lender shall inform the Agent that such Lender has determined that United States dollar deposits in the amount of any LIBOR Portion scheduled to be outstanding during such Interest Period are not readily available to such Lender in the offshore interbank market or (b) the Required Lenders shall advise the Agent that LIBOR as determined by the Agent will not adequately and fairly reflect the cost to such Lenders of funding such LIBOR Portion for such Interest Period, the Agent shall -11- promptly give notice thereof to the Company and each other Lender and the obligations of the Lenders to create, continue or effect by conversion any LIBOR Portion in such amount and for such Interest Period shall terminate until the circumstances giving rise to such termination no longer exist. Section 2.7. Taxes and Increased Costs. With respect to the LIBOR Portions, if any Lender shall determine in good faith that any change in any applicable law, treaty, regulation or guideline (including, without limitation, Regulation D of the Board of Governors of the Federal Reserve System) or any new law, treaty, regulation or guideline, or any interpretation of any of the foregoing by any governmental authority charged with the administration thereof or any central bank or other fiscal, monetary or other authority having jurisdiction over such Lender or its lending branch or the Portions contemplated by this Agreement (whether or not having the force of law) shall: (i) impose, increase, or deem applicable any reserve, special deposit or similar requirement against assets held by, or deposits in or for the account of, or loans by, or any other acquisition of funds or disbursements by, such Lender which is not in any instance already accounted for in computing the Adjusted LIBOR Rate; (ii) subject such Lender, the LIBOR Portions or any Note to the extent it evidences such Portions, to any tax (including, without limitation, any United States interest equalization tax or similar tax however named applicable to the acquisition or holding of debt obligations and any interest or penalties with respect thereto), duty, charge, stamp tax, fee, deduction or withholding in respect of this Agreement, any LIBOR Portion or any Note to the extent it evidences such a Portion, except such taxes as may be measured by the overall net income or gross receipts of such Lender or its lending branches and imposed by the jurisdiction, or any political subdivision or taxing authority thereof, in which such Lender's principal executive office or its lending branch is located; (iii) change the basis of taxation of payments of principal and interest due from the Company to such Lender hereunder or under any Note to the extent it evidences any LIBOR Portion (other than by a change in taxation of the overall net income or gross receipts of such Lender or its lending branches); or (iv) impose on such Lender any penalty with respect to the foregoing or any other condition regarding this Agreement, any LIBOR Portion, or any Note to the extent it evidences any LIBOR Portion; and such Lender shall determine that the result of any of the foregoing is to increase the cost (whether by incurring a cost or adding to a cost) to such Lender of creating or maintaining any LIBOR Portion hereunder or to reduce the amount of principal or interest received or receivable by such Lender, then the Company shall pay on demand to the Agent for the account of such Lender from time to time as specified by such Lender such additional amounts as such Lender shall reasonably determine are sufficient to compensate and indemnify it for such increased cost or reduced amount. If a Lender makes such a claim for -12- compensation, it shall provide to the Company (with a copy to the Agent) a certificate setting forth in reasonable detail the computation of the increased cost or reduced amount as a result of any event mentioned herein and such certificate shall be deemed prima facie correct. Section 2.8. Funding Indemnity. In the event any Lender shall incur any loss, cost or expense (including, without limitation, any loss (including loss of profit), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired or contracted to be acquired by such Lender to fund or maintain its part of any LIBOR Portion or the relending or reinvesting of such deposits or other funds or amounts paid or prepaid to such Lender) as a result of: (i) any payment of a LIBOR Portion on a date other than the last day of the then applicable Interest Period for any reason, whether before or after default, and whether or not such payment is required by any provisions of this Agreement; or (ii) any failure by any of the Company to create, borrow, continue or effect by conversion a LIBOR Portion on the date specified in a notice given pursuant to this Agreement; then, upon the demand of such Lender, the Company shall pay on demand to the Agent for the account of such Lender such amount as will reimburse such Lender for such loss, cost or expense. If a Lender requests such a reimbursement, it shall provide the Company (with a copy to the Agent) with a certificate setting forth in reasonable detail the computation of the loss, cost or expense giving rise to the request for reimbursement and such certificate shall be deemed prima facie correct. Section 2.9. Lending Branch. Each Lender may, at its option, elect to make, fund or maintain its Loans hereunder at the branches or offices specified on the signature pages hereof or on any Assignment Agreement executed and delivered pursuant to Section 11.18 hereof or at such other of its branches or offices as such Lender may from time to time elect. To the extent reasonably possible, a Lender shall designate an alternative branch or funding office with respect to its pro rata share of the LIBOR Portions to reduce any liability of the Company to such Lender under Section 2.7 hereof or to avoid the unavailability of an interest rate option under Section 2.6 hereof, so long as such designation is not otherwise disadvantageous to the Lender. Section 2.10. Discretion of Lenders as to Manner of Funding. Notwithstanding any provision of this Agreement to the contrary, each Lender shall be entitled to fund and maintain its funding of all or any part of its Notes in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder (including determinations under Sections 2.6, 2.7 and 2.8 hereof) shall be made as if each such Lender had actually funded and maintained its share of each LIBOR Portion during each Interest Period applicable thereto through the purchase of deposits in the offshore interbank market in the amount of its share of such LIBOR Portion, having a maturity corresponding to such Interest Period and bearing an interest rate equal to LIBOR for such Interest Period. -13- Section 2.11. Computation of Interest. All interest on the Notes, and all fees, charges and commissions due hereunder, shall be computed on the basis of a year of 360 days for the actual number of days elapsed, except that interest on the Domestic Rate Portions of the Notes and on Reimbursement Obligations with respect to Letters of Credit shall be computed on the basis of a year of 365 or 366 days (as the case may be) for the actual number of days elapsed. Section 2.12. Capital Adequacy. If any Lender shall determine that any applicable law, rule or regulation regarding capital adequacy instituted after the date hereof, or any change in the interpretation or administration of any applicable law, rule or regulation regarding capital adequacy by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof or compliance by such Lender (or its lending office) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Lender's capital as a consequence of its obligations hereunder or credit extended by it hereunder to a level below that which such Lender could have achieved but for such law, rule, regulation, change or compliance (taking into consideration such Lender's policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, within 15 days after demand by such Lender, the Company shall pay to the Agent for the account of such Lender such additional amount or amounts as will compensate such Lender for such reduction. Any Lender claiming compensation under this Section shall accompany its demand for compensation with a certificate (with a copy to the Agent) setting forth the additional amount or amounts to be paid to it hereunder in reasonable detail, which certificate shall be conclusive if reasonably determined. In determining such amount, such Lender may use any reasonable averaging and attribution methods. SECTION 3. FEES, PAYMENTS, REDUCTIONS, APPLICATIONS AND NOTATIONS. Section 3.1. Revolving Credit Commitment Fee. For the period from the date hereof to but not including the Termination Date, the Company shall pay to the Agent for the account of the Lenders in accordance with their Percentages a commitment fee at the rate per annum equal to 3/8 of 1% per annum on the average daily unused amount of the Revolving Credit Commitments hereunder. Such fee shall be payable in arrears on the last day of each March, June, September, and December in each year (commencing with the first of such dates after the date hereof) and on the Termination Date. Section 3.2. Acquisition Financing Commitment Fee. For the period from the date hereof to but not including the Acquisition Financing Termination Date, the Company shall pay to the Agent for the account of the Lenders in accordance with their Percentages a commitment fee at the rate per annum equal to 1/2 of 1% per annum on the average daily unused amount of the Acquisition Financing Commitments hereunder. For purposes of this Section, Supplemental Revolving Loans shall be deemed a utilization of the Acquisition Financing Commitments. Such fee shall be payable in arrears on the last day of each March, June, September, and December in each year (commencing with the first of such dates after the date hereof) and on the date the Acquisition Financing Termination Date. -14- Section 3.3. Letter of Credit Fees. Quarterly in arrears, on the last day of each March, June, September, and December in each year (commencing on the first of such dates after the date hereof), the Company shall pay to the Agent, for the benefit of the Lenders, a letter of credit fee at the rate of 1% per annum applied to the daily average face amount of Letters of Credit outstanding during such quarter. In addition, the Company shall pay to the Agent for its own use and benefit the Agent's standard drawing, negotiation, amendment and other administrative fees for each Letter of Credit, as such standard fees may be established by the Agent from time to time. Section 3.4. Audit Fees. The Company shall pay to the Agent for its own use and benefit charges for audits of the Collateral by the Agent in such amounts as the Agent may from time to time request (the Agent acknowledging and agreeing that such charges shall be computed in the same manner as it at the time customarily uses for the assessment of charges for similar collateral audits); provided, however, that in the absence of any Default or Event of Default, the Company shall not be required to pay the Agent for more than one such audit per calendar year. Section 3.5. Agent's Fee. The Company shall pay to the Agent, for its own use and benefit, such agency and arrangement fees as may from time to time be mutually agreed upon by the Company and the Agent. Section 3.6. Voluntary Prepayments. The Company shall have the privilege of prepaying the Revolving Credit Notes and the Supplemental Revolving Credit Notes in whole or in part (but if in part, then in a minimum amount of $50,000 or such greater amount which is an integral multiple of $50,000) and the Acquisition Financing Notes and the Term Notes in whole or in part (but if in part, then in a minimum amount of $100,000 or such greater amount which is an integral multiple of $100,000) at any time upon 1 Business Day's prior notice to the Agent (such notice if received subsequent to 12:00 noon Chicago time on a given day to be treated as though received at the opening of business on the next Business Day), which shall promptly so notify the Lenders, by paying to the Agent for the account of the Lenders the principal amount to be prepaid and (i) if such a prepayment prepays the Term Notes relating to the same Borrowing in full, accrued interest thereon to the date of prepayment, (ii) if such a prepayment prepays the Revolving Credit Notes in full and is accompanied by the termination in whole of the Revolving Credit Commitments, accrued interest thereon to the date of prepayment plus any commitment fee which has accrued and is unpaid plus any prepayment fee due under Section 3.8 hereof, (iii) if such a prepayment prepays the Acquisition Financing Notes in full and is accompanied by the termination in whole of the Acquisition Financing Commitments, accrued interest thereon to the date of prepayment plus any commitment fee which has accrued and is unpaid plus any prepayment fee due under Section 3.8 hereof, (iv) if such a prepayment prepays the Supplemental Revolving Credit Notes in full and is accompanied by the termination in whole of the Supplemental Revolving Credit Commitments, accrued interest thereon to the date of prepayment plus any prepayment fee due under Section 3.8 hereof, and (v) any amounts due to the Lenders under Section 2.8 hereof. -15- Section 3.7. Mandatory Prepayments. (a) The Company covenants and agrees that if at any time the sum of the unpaid principal balance of the Revolving Loans and the L/C Obligations outstanding at any one time shall be in excess of the Borrowing Base as then determined and computed, the Company shall immediately and without notice or demand pay over the amount of the excess to the Agent for the account of the Lenders as and for a mandatory prepayment on such Obligations, with each such prepayment first to be applied to the Revolving Credit Notes until payment in full thereof with any remaining balance to be held by the Agent as collateral security for the Obligations owing under the Applications with respect to the Letters of Credit. (b) On January 31st of each year (commencing January 31, 1999), the Company shall pay over to the Agent for the account of the Lenders as and for a mandatory prepayment on the Acquisition Financing Notes and the Term Notes an amount equal to 50% of Excess Cash Flow for the most recently completed fiscal year, provided that if the ratio of Total Senior Funded Debt as of the last day of the fiscal year then ended to Adjusted EBITDA for the fiscal year then ended is less than 3.0 to 1.0, then the mandatory prepayment due hereunder shall be reduced to 25% of Excess Cash Flow for such year. Mandatory prepayments of the Acquisition Financing Notes and Term Notes pursuant to this Section 3.7(b) shall be applied first to the Term Notes then outstanding (which application shall be made to the most recent Borrowing of Term Loans made to the Company and applied to the several installments thereon in the inverse order of maturity) and then to the Acquisition Financing Notes. (c) The Company covenants and agrees that if at any time the sum of the unpaid principal balance of the Supplemental Revolving Loans then outstanding plus the original principal amount of all Acquisition Financing Loans made hereunder (determined without regard to any subsequent payments of principal thereon) shall be in excess of the difference between the sum of $65,000,000 plus any portion (up to $5,000,000) of the Revolving Credit Commitments converted into Acquisition Financing Commitments pursuant to Section 1.7 hereof, minus all amounts of the Acquisition Financing Commitments voluntarily terminated pursuant to Section 3.8 hereof, the Company shall immediately and without notice or demand pay over the amount of the excess to the Agent for the account of the Lenders as and for a mandatory prepayment on the Supplemental Revolving Credit Notes. (d) If the Company or any Subsidiary shall at any time or from time to time make or agree to make a Disposition or shall suffer an Event of Loss resulting in Net Cash Proceeds in excess of $1,000,000 in any fiscal year of the Company, then (x) the Company shall promptly notify the Agent of such proposed Disposition or Event of Loss (including the amount of the estimated Net Cash Proceeds to be received by the Company or such Subsidiary in respect thereof) and (y) promptly upon, and in no event later than the Business Day after, receipt by the Company or the Subsidiary of the Net Cash Proceeds of such Disposition or Event of Loss, the Company shall prepay the Acquisition Financing Notes and the Term Notes in an aggregate amount equal to 100% of the amount of such Net Cash Proceeds; provided that in the case of each Disposition and Event of Loss, if the Company states in its notice of such event that the Company or the applicable Subsidiary intends to reinvest, within 180 days of the applicable Disposition or receipt of Net Cash Proceeds from -16- an Event of Loss, the Net Cash Proceeds thereof in assets in a Permitted Line of Business, then so long as no Default or Event of Default then exists, the Company shall not be required to make a mandatory prepayment under this Section 3.7(d) in respect of such Net Cash Proceeds to the extent such Net Cash Proceeds are actually reinvested in such similar assets within such 180 day period. Promptly after the end of such 180-day period, the Company shall notify the Agent whether the Company or such Subsidiary has reinvested such Net Cash Proceeds in assets in a Permitted Line of Business, and to the extent such Net Cash Proceeds have not been so reinvested, the Company shall promptly prepay the Acquisition Financing Notes and Term Notes in the amount of such Net Cash Proceeds not so reinvested. The amount of each such prepayment shall be applied first to the Term Notes then outstanding (which application shall be made to the most recent Borrowing of Term Loans made to the Company and applied to the several installments thereon in the inverse order of maturity) and then to the Acquisition Financing Notes. The Company acknowledges that its performance hereunder shall not limit the rights and remedies of the Lenders for any breach of any other provisions of this Agreement. (e) Notwithstanding anything in Sections 3.7(a), (b), (c) or (d) to the contrary, prior to the final maturity of the relevant Notes, the Company shall not be required to make any prepayment of any LIBOR Portions pursuant to Section 3.7(a), (b), (c) or (d) until the last day of the Interest Period with respect thereto (provided that, in the case of clause (d), any such cash collateral shall have the same effect as a prepayment of the Loans for purposes of the Senior Subordinated Notes or any issue of Subordinated Debt requiring that Subordinated Debt be retired out of the proceeds of any such Disposition or Event of Loss after giving effect to any mandatory prepayment of the Obligations) so long as (i) no Default or Event of Default then exists and (ii) an amount equal to the principal amount of such LIBOR Portions is deposited by the Company in a segregated cash collateral account with the Agent for the benefit of the Lenders to be held in such account on terms reasonably satisfactory to the Agent. The amount held on deposit in such account shall if and when requested by the Company be invested in direct obligations of, or obligations the principal of and interest on which are unconditionally guaranteed by, the United States of America with a remaining maturity of one year or less, or other investments mutually satisfactory to the Company and the Agent. On the last day of such Interest Period, the amount held in such account shall be applied so as to make such prepayment, and except during the continuance of any Default or Event of Default, any balance remaining on deposit in such account after such application shall be remitted to the Company. Section 3.8. Terminations. (a) Voluntary. The Company shall have the privilege upon 1 Business Day's prior notice to the Agent (which shall promptly notify the Lenders) to ratably terminate the Revolving Credit Commitments and/or the Acquisition Financing Commitments and/or the Supplemental Revolving Credit Commitments in whole or in part (but if in part then in the amount of $500,000 or such greater amount which is an integral multiple of $500,000) and upon payment of any prepayment premium required by the terms of the following sentence. On the effective date of any such termination of the Commitments, or any part thereof, the Company shall pay as a prepayment premium to the Agent for the account of the Lenders, as liquidated damages for the loss of bargain and not as a penalty, an amount equal to 3/8 of 1% per annum, in the case of any termination of the -17- Revolving Credit Commitments, and 1/2 of 1% per annum, in the case of any termination of the Acquisition Financing Commitments, times the aggregate Commitments then being terminated multiplied by a fraction, the numerator of which is the number of days remaining in the initial 12-month term of this Agreement and the denominator of which is 360 days. No partial terminations of the Revolving Credit Commitments may be made below the L/C Commitment then in effect, unless the L/C Commitment is concurrently reduced by a like amount. No partial terminations of the Acquisition Financing Commitments may be made below the Supplemental Revolving Credit Commitments then in effect, unless the Supplemental Revolving Credit Commitments are concurrently reduced by a like amount. Not later than the termination date stated in such notice, there shall be made such payments to the Agent as may be necessary to reduce the sum of the aggregate outstanding principal amount of the relevant Loans to the amount to which the relevant Commitments have been reduced, together with (x) any amount due the Lenders under this Section 3.8 and under Section 2.8 hereof and (y) in the case of a termination in whole, all interest, fees and other amounts due on the Obligations. The foregoing to the contrary notwithstanding, (i) no termination of the Revolving Credit Commitment may be effected hereunder if as a result thereof the outstanding aggregate amount of L/C Obligations would exceed the L/C Commitment as reduced by such termination and (ii) the relevant Commitments may not be terminated below $5,000,000 except concurrently with their termination in whole. (b) Mandatory Revolving Credit Terminations. If at any time Net Cash Proceeds remain after the prepayment of the Acquisition Financing Notes and Term Notes in full pursuant to Section 3.7(d) hereof, the Acquisition Financing Commitments and the Revolving Credit Commitments shall terminate by an amount equal to 100% of such excess proceeds (first to the Acquisition Financing Commitments until reduced to zero and then to the Revolving Credit Commitments). (c) Mandatory Termination Upon a Change of Control. After the occurrence of a Change of Control, the Required Lenders may, by written notice to the Company at any time on or before the date occurring 90 days after the date the Company notifies the Lenders of such Change of Control, terminate the remaining Commitments and all other obligations of the Lenders hereunder on the date stated in such notice (which shall in no event be sooner than 30 days after the occurrence of such Change of Control). On the date the Commitments are so terminated, all outstanding Obligations (including, without limitation, all principal of and accrued interest on the Notes) shall forthwith be due and payable without further demand, presentment, protest, or notice of any kind and the Company shall immediately pay to the Lenders the full amount then available for drawing under each Letter of Credit, such amount to be held by the Agent as collateral security for the Letters of Credit and the Applications therefor and any remaining Obligations (the Company agreeing to immediately make such payment on the date the Commitments are so terminated and acknowledging and agreeing that the Lenders would not have an adequate remedy at law for the failure by the Company to honor any such demand and that the Lenders, and the Agent on their behalf, shall have the right to require the Company to specifically perform such undertaking whether or not any drawings or other demands for payment have been made under any of the Letters of Credit). -18- (d) Any termination of the Commitments pursuant to this Section may not be reinstated. Section 3.9. Place and Application. All payments of principal, interest, fees and any other Obligations shall be made to the Agent at its office 111 West Monroe Street, Chicago, Illinois (or at such other place as the Agent may specify) in immediately available and freely transferable funds at the place of payment. All such payments shall be made without set-off or counterclaim and without reduction for, and free from, any and all present or future taxes, levies, imposts, duties, fees, charges, deductions, withholdings, restrictions or conditions of any nature imposed by any government or political subdivision or taxing authority thereof. Payments received by the Agent after 12:00 noon Chicago time shall be deemed received as of the opening of business on the next Business Day. Except as herein provided, all payments shall be received by the Agent for the ratable account of the Lenders and shall be promptly distributed by the Agent to the Lenders in accordance with their Percentages. Unless the Company otherwise directs, payments (including prepayments) on any Loans shall be deemed first applied to the applicable Domestic Rate Portion until payment in full thereof, with any balance applied to the LIBOR Portions in the order in which their Interest Periods expire. Any amount prepaid on the Revolving Credit Notes or Supplemental Revolving Credit Notes may, subject to all of the terms and conditions hereof, be borrowed, repaid and borrowed again. No amounts prepaid on the Acquisition Financing Notes or the Term Notes may be reborrowed, and any partial prepayments (whether voluntary or mandatory) shall be applied to the several installments of such Notes in the inverse order of maturity. All payments (whether voluntary or required) shall be accompanied by any amount due the Lenders under Section 2.8 hereof, but no acceptance of such a payment without requiring payment of amounts due under Section 2.8 shall preclude a later demand by the Lenders for any amount due them under Section 2.8 in respect of such payment. Anything contained herein to the contrary notwithstanding, all payments and collections received in respect of the Obligations and all proceeds of the Collateral received, in each instance, by the Agent or any of the Lenders after the occurrence and during the continuation of an Event of Default shall be remitted to the Agent and distributed as follows: (a) first, to the payment of any outstanding costs and expenses incurred by the Agent in monitoring, verifying, protecting, preserving or enforcing the Liens on the Collateral or by the Agent in protecting, preserving or enforcing rights under the Loan Documents, and in any event all costs and expenses of a character which the Company has agreed to pay under Section 11.5 hereof (such funds to be retained by the Agent for its own account unless the Agent has previously been reimbursed for such costs and expenses by the Lenders, in which event such amounts shall be remitted to the Lenders to reimburse them for payments theretofore made to the Agent); (b) second, to the payment of any outstanding interest or other fees or amounts due under the Notes and the other Loan Documents, in each case other than for principal or in reimbursement or collateralization of L/C Obligations, ratably as -19- among the Agent and the Lenders in accord with the amount of such interest and other fees or amounts owing each; (c) third, to the payment of the principal of the Notes and any unpaid Reimbursement Obligations and to the Agent to be held as collateral security for any other L/C Obligations (until the Agent is holding an amount of cash equal to the then outstanding amount of all such L/C Obligations), the aggregate amount paid to or held as collateral security for the Lenders to be allocated pro rata as among the Lenders in accordance with the then respective aggregate unpaid principal balances of their Loans and interests in the Letters of Credit; (d) fourth, to the Agent and the Lenders ratably in accordance with the amounts of any other indebtedness, obligations or liabilities of the Company owing to each of them and secured by the Collateral Documents (other than those described in clause (e) below) unless and until all such indebtedness, obligations and liabilities have been fully paid and satisfied; (e) fifth, to the payment of the Hedging Liability (if any) pro rata as among the Lenders to whom such Hedging Liability is owed in accordance with the then respective unpaid amounts of such liability; and (f) fifth, to the Company or whoever else may be lawfully entitled thereto. In the event that the amount of any Hedging Liability is not fixed and determined at the time any funds are to be allocated thereto pursuant to the above provisions, such funds so allocated shall be held by the Agent as collateral security until such Hedging Liability is fixed and determined and the same shall then be applied to the Hedging Liability, with any surplus reallocated among the Lenders, to cover any deficiency which would not have existed had the exact amount of the Hedging Liability been known at the time such funds were originally distributed. Section 3.10. Notations and Requests. All Borrowings made against the Notes, the status of all amounts evidenced by the Notes as constituting part of the applicable Domestic Rate Portion or LIBOR Portion and the rates of interest and Interest Periods applicable to such Portions shall be recorded by the Lenders on their books or, at their option in any instance, endorsed on the reverse side of the Notes and the unpaid principal balances and status, rates and Interest Periods so recorded or endorsed by the Lenders shall be prima facie evidence in any court or other proceeding brought to enforce the Notes of the principal amount remaining unpaid thereon, the status of such Borrowings and the interest rates and Interest Periods applicable thereto. Prior to any negotiation of any Note, the Lender holding such Note shall endorse thereon the status of all amounts evidenced thereby as constituting part of the Domestic Rate Portion or LIBOR Portion and the rates of interest and the Interest Periods applicable thereto. -20- SECTION 4. THE COLLATERAL AND GUARANTIES. Section 4.1. Collateral. The Obligations shall be secured by valid and enforceable security interests in and liens on all now owned or hereafter acquired accounts, general intangibles, instruments, documents, chattel paper, investment property, inventory, equipment, real estate and certain other goods and assets of the Company and of each Restricted Subsidiary pursuant to one or more Collateral Documents from such Persons, each in form and substance satisfactory to the Agent.

In the event the Company or any Restricted Subsidiary forms or acquires any Restricted Subsidiary after the date hereof, the Company shall within 10 Business Days of such formation or acquisition cause such newly formed or acquired Restricted Subsidiary to execute a Guaranty and such Collateral Documents as the Agent may then require, and the Company shall also deliver, or cause such Restricted Subsidiary to deliver, at the Company's cost and expense, such other instruments, documents, certificates, and opinions required by the Agent in connection therewith.

In the event that the Company or any Restricted Subsidiary owns or hereafter acquires any real property, at the request of the Required Lenders, the Company shall, or shall cause such Restricted Subsidiary to, execute and deliver to the Agent (or a security trustee therefor) a mortgage or deed of trust acceptable in form and substance to the Agent for the purpose of granting to the Agent for the benefit of the Lenders a lien on such real property to secure the Obligations, shall pay all taxes, costs and expenses incurred by the Agent in recording such mortgage or deed of trust, and shall at its expense supply to the Agent a Phase I environmental site assessment, a survey and a mortgagee's policy of title insurance from a title insurer reasonably acceptable to the Agent insuring the validity of such mortgage or deed of trust and its status as a first lien (subject to liens permitted by this Agreement) on the real property encumbered thereby.

Each Lender hereby appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers hereunder and under the other Loan Documents as are designated to the Agent by the terms hereof and thereof together with such powers as are reasonably incidental thereto. The Lenders expressly agree that the Agent is not acting as a fiduciary of the Lenders in respect of the Loan Documents, the Company or otherwise, and nothing herein or in any of the other Loan Documents shall result in any duties or obligations on the Agent or any of the Lenders except as expressly set forth herein. The Agent may resign at any time by sending 20 days prior written notice to the Company and the Lenders. In the event of any such resignation, the Required Lenders may appoint a new agent after consultation with the Company (and, so long as no Default or Event of Default exists, the Company's prior written consent) which shall succeed to all the rights, powers and duties of the Agent hereunder and under the other Loan Documents. Any resigning Agent shall be entitled to the benefit of all the protective provisions hereof with respect to its acts as an agent hereunder, but no successor Agent shall in any event be liable or responsible for any actions of its predecessor. If the Agent resigns and no successor is appointed, the rights and obligations of such Agent shall be automatically assumed by the Required Lenders and (i) the Company shall be directed to make all payments due each Lender hereunder directly to such Lender and (ii) the Agent's rights in the Collateral Documents shall be assigned without representation, recourse or warranty to the Lenders as their interests may appear. Section 10.2. Rights as a Lender. The Agent has and reserves all of the rights, powers and duties hereunder and under the other Loan Documents as any Lender may have and may exercise the same as though it was not the Agent. The terms "Lender" and "Lenders" as used herein and in all other Loan Documents shall, unless the context otherwise expressly indicates, include the Agent in its individual capacity as Lender. Section 10.3. Standard of Care. The Lenders acknowledge that they have received and approved copies of the Loan Documents and such other information and documents concerning the transactions contemplated and financed hereby as they have requested to receive and/or review. The Agent makes no representations or warranties of any kind or character to the Lenders with respect to the validity, enforceability, genuineness, perfection, value, worth or collectibility hereof or of the Notes or any of the other Obligations or of the Loan Documents or of the Liens provided for thereby or of any other documents called for hereby or thereby or of the Collateral. The Agent need not verify the worth or existence of the Collateral and may rely exclusively on reports of the Company with respect thereto. Neither the Agent nor any director, officer, employee, agent or representative thereof (including any security trustee therefor) shall in any event be liable for any clerical errors or errors in judgment, inadvertence or oversight, or for action taken or omitted to be taken by it or them hereunder or under the Loan Documents or in connection herewith or therewith except for its or their own gross negligence or willful misconduct. The Agent shall not incur any liability to the Lenders under or in respect of this Agreement or any other Loan Documents by acting upon any notice, certificate, warranty, instruction or statement (oral or written) of anyone (including anyone in good faith believed by it to be -61- authorized to act on behalf of the Company), unless it has actual knowledge of the untruthfulness of same. The Agent may execute any of its duties hereunder by or through representatives, employees, agents, and attorneys-in-fact and shall not be answerable to the Lenders for the default or misconduct of any such representatives, employees, agents or attorneys-in-fact selected with reasonable care. The Agent shall be entitled to advice of counsel concerning all matters pertaining to the agency hereby created and its duties hereunder, and shall incur no liability to the Lenders and be fully protected in acting upon the advice of such counsel. The Agent shall be entitled to assume that no Default or Event of Default exists unless notified to the contrary by a Lender. The Agent shall in all events be fully protected in acting or failing to act in accordance with the instructions of the Required Lenders. Upon the occurrence of an Event of Default hereunder, the Agent shall take such action with respect to the enforcement of its Liens on the Collateral and the preservation and protection thereof as it shall be directed to take by the Required Lenders but, unless and until the Required Lenders have given such direction, the Agent shall take or refrain from taking such actions as the Agent determines are appropriate and in the best interest of all Lenders. The Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by the Agent by reason of taking or continuing to take any such action. The Agent may treat the owner of any Note as the holder thereof until written notice of transfer shall have been filed with the Agent signed by such owner in form satisfactory to the Agent. Each Lender acknowledges that it has independently and without reliance on the Agent or any other Lender and based upon such information, investigations and inquiries as it deems appropriate made its own credit analysis and decision to extend credit to the Company. It shall be the responsibility of each Lender to keep itself informed as to the creditworthiness of the Company and the Agent shall have no liability to any Lender with respect thereto. Section 10.4. Costs and Expenses. Each Lender agrees to reimburse the Agent for all costs and expenses (including, without limitation, reasonable attorneys' fees) suffered or incurred by the Agent or any security trustee in performing its duties hereunder and under the other Loan Documents, or in the exercise of any right or power imposed or conferred upon the Agent hereby or thereby, to the extent that the Agent is not promptly reimbursed for same by the Company after making request of the Company for payment thereof, or out of the Collateral, all such costs and expenses to be borne by the Lenders ratably in accordance with their Percentages. If any Lender fails to reimburse the Agent for its share of any such costs and expenses, such costs and expenses shall be paid pro rata by the remaining Lenders, but without in any manner releasing the defaulting Lender from its liability hereunder. Section 10.5. Indemnity. The Lenders shall ratably indemnify and hold the Agent, and its directors, officers, employees, agents, representatives or attorneys-in-fact (including as such any security trustee therefor), harmless from and against any liabilities, losses, costs or expenses suffered or incurred by it hereunder or under the other Loan Documents or in connection with the transactions contemplated hereby or thereby, regardless of when asserted or arising, except to the extent it is promptly reimbursed for the same by the Company or out of the Collateral and except to the extent that any event giving rise to a -62- claim was caused by the gross negligence or willful misconduct of the party seeking to be indemnified. If any Lender defaults in its obligations hereunder, its share of the obligations shall be paid pro rata by the remaining Lenders, but without in any manner releasing the defaulting Lender from its liability hereunder. SECTION 11. MISCELLANEOUS. Section 11.1. Withholding Taxes. (a) Payments Free of Withholding. Except as otherwise required by law and subject to Section 11.1(b) hereof, each payment by the Company under this Agreement or the other Loan Documents shall be made without withholding for or on account of any present or future taxes (other than overall net income taxes on the recipient) imposed by or within the jurisdiction in which the Company is domiciled, any jurisdiction from which the Company makes any payment, or (in each case) any political subdivision or taxing authority thereof or therein. If any such withholding is so required, the Company shall make the withholding, pay the amount withheld to the appropriate governmental authority before penalties attach thereto or interest accrues thereon and forthwith pay such additional amount as may be necessary to ensure that the net amount actually received by each Lender and the Agent free and clear of such taxes (including such taxes on such additional amount) is equal to the amount which that Lender or the Agent (as the case may be) would have received had such withholding not been made. If the Agent or any Lender pays any amount in respect of any such taxes, penalties or interest the Company shall reimburse the Agent or that Lender for that payment on demand in the currency in which such payment was made. If the Company pays any such taxes, penalties or interest, it shall deliver official tax receipts evidencing that payment or certified copies thereof to the Lender or Agent on whose account such withholding was made (with a copy to the Agent if not the recipient of the original) on or before the thirtieth day after payment. (b) U.S. Withholding Tax Exemptions. Each Lender that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) shall submit to the Company and the Agent on or before the earlier of the date the initial Borrowing is made hereunder and 30 days after the date hereof, two duly completed and signed copies of either Form 1001 (relating to such Lender and entitling it to a complete exemption from withholding under the Code on all amounts to be received by such Lender, including fees, pursuant to the Loan Documents and the Obligations) or Form 4224 (relating to all amounts to be received by such Lender, including fees, pursuant to the Loan Documents and the Obligations) of the United States Internal Revenue Service. Thereafter and from time to time, each Lender shall submit to the Company and the Agent such additional duly completed and signed copies of one or the other of such Forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may be (i) requested by the Company in a written notice, directly or through the Agent, to such Lender and (ii) required under then-current United States law or regulations to avoid or reduce United States withholding taxes on payments in respect of all amounts to be received by such Lender, including fees, pursuant to the Loan Documents or the Obligations. -63- (c) Inability of Lender to Submit Forms. If any Lender determines, as a result of any change in applicable law, regulation or treaty, or in any official application or interpretation thereof, that it is unable to submit to the Company or Agent any form or certificate that such Lender is obligated to submit pursuant to subsection (b) of this Section 11.1 or that such Lender is required to withdraw or cancel any such form or certificate previously submitted or any such form or certificate otherwise becomes ineffective or inaccurate, such Lender shall promptly notify the Company and the Agent of such fact and the Lender shall to that extent not be obligated to provide any such form or certificate and will be entitled to withdraw or cancel any affected form or certificate, as applicable. Section 11.2. Non-Business Days. If any payment hereunder becomes due and payable on a day which is not a Business Day, the due date of such payment shall be extended to the next succeeding Business Day on which date such payment shall be due and payable. In the case of any payment of principal falling due on a day which is not a Business Day, interest on such principal amount shall continue to accrue during such extension at the rate per annum then in effect, which accrued amount shall be due and payable on the next scheduled date for the payment of interest. Section 11.3. No Waiver, Cumulative Remedies. No delay or failure on the part of the Agent or any Lender in the exercise of any power or right shall operate as a waiver thereof or as an acquiescence in any default, nor shall any single or partial exercise of any right preclude any other or further exercise thereof or the exercise of any other power or right. The rights and remedies hereunder of the Agent and the Lenders are cumulative to, and not exclusive of, any rights or remedies which any of them would otherwise have. Section 11.4. Waivers, Modifications and Amendments. Any provision hereof or of the other Loan Documents may be amended, modified, waived or released and any Default or Event of Default and its consequences may be rescinded and annulled upon the written consent of the Company and the Required Lenders; provided, however, that without the written consent of each Lender no such amendment, modification or waiver shall increase the amount or extend the terms of such Lender's Commitments or reduce the amount of any principal of or interest rate applicable to, or extend the maturity of, any Obligation owed to it or reduce the amount of fees or other amounts to which it is entitled hereunder or release any guaranty of any Obligations or release all or any substantial (in value) part of the collateral security afforded by the Loan Documents (except in connection with a sale or other disposition permitted to be effected by the provisions hereof or of the Loan Documents) or change this Section 11.4 or change the definition of "Required Lenders" or change the number of Lenders required to take any action hereunder or under the other Loan Documents. No amendment, modification or waiver of the Agents' protective provisions shall be effective without the prior written consent of the Agent. Section 11.5. Costs and Expenses.

The Company agrees to indemnify and save the Lenders, the Agent and any security trustee for the Agent or the Lenders harmless from any and all liabilities, losses, costs and expenses incurred by the Lenders or the Agent in connection with any action, suit or proceeding brought against the Agent, any security trustee or any Lender by any Person which arises out of the transactions contemplated or financed by any of the Loan Documents or out of any action or inaction by the Agent, any security trustee or any Lender thereunder, including without limitation those caused by the negligence of any party but except for such thereof as is caused by the gross negligence or willful misconduct of the party indemnified and except for costs or liabilities incurred in suits which are exclusively among the Lenders or the Lenders and the Agent. The provisions of this Section 11.5 and the protective provisions of Section 2 hereof shall survive payment of the Obligations. (b) The Company unconditionally agrees to forever indemnify, defend and hold harmless, and covenants not to sue for any claim for contribution against, the Agent and the Lenders for any damages, costs, loss or expense, including without limitation, response, remedial or removal costs, arising out of any of the following: (i) any presence, release, threatened release or disposal of any hazardous or toxic substance or petroleum by the Company or any Subsidiary or otherwise occurring on or with respect to its property (whether owned or leased), (ii) the operation or violation of any environmental law, whether federal, state, or local, and any regulations promulgated thereunder, by the Company or any Subsidiary or otherwise occurring on or with respect to its property (whether owned or leased), (iii) any claim for personal injury or property damage in connection with the Company or any Subsidiary or otherwise occurring on or with respect to its property (whether owned or leased), and (iv) the inaccuracy or breach of any environmental representation, warranty or covenant by the Company or any Subsidiary made herein or in any promissory note, mortgage, deed of trust, security agreement or any other instrument or document evidencing or securing any Obligations or setting forth terms and conditions applicable thereto or otherwise relating thereto, except for damages arising from the willful misconduct or gross negligence of, or material breach of the Loan Documents by, the party claiming indemnification. This indemnification shall survive the payment and satisfaction of all Obligations and the termination of this Agreement, and shall remain in force beyond the expiration of any applicable statute of limitations and payment or satisfaction in full of any single claim under this indemnification. This indemnification shall be binding upon the successors and assigns of the Company and shall inure to the benefit of Agent and the Lenders and their directors, officers, employees, agents, and collateral trustees, and their successors and assigns. -65- Section 11.6. Documentary Taxes.

Upon the execution of each Assignment Agreement by the assigning Lender thereunder, the assignee lender thereunder, the Company and the Agent and payment to such assigning Lender by such assignee lender of the purchase price for the portion of the indebtedness of the Company being acquired by it, (i) such assignee lender shall thereupon become a "Lender" for all purposes of this Agreement with Commitments in the amount set forth in such Assignment Agreement and with all the rights, powers and obligations afforded a Lender hereunder, (ii) such assigning Lender shall have no further liability for funding the portion of its Commitments assumed by such other Lender and (iii) the address for notices to such assignee Lender shall be as specified in the Assignment Agreement executed by it. Concurrently with the execution and delivery of such Assignment Agreement, the Company shall execute and deliver Notes to the assignee Lender in the respective amounts of its Commitments and new Notes to the assigning Lender in the respective amounts of its Commitments after giving effect to the reduction occasioned by such assignment, all such Notes to constitute "Notes" for all purposes of this Agreement and the other Loan Documents.

Except for those already obtained, no order, authorization, consent, license or exemption of, or filing or registration with, any court or governmental department, agency, instrumentality or regulatory body, whether local, state or federal, is or will be required in connection with the lawful execution and delivery of the Loan Documents to which any Transaction Party is a party or the observance and performance by such Person of any of the terms thereof.
