Section 2.   COMMITMENT OF THE BANK.

2.1.   Revolving Loans.

(a)    Revolving Loan Commitment. Subject to the terms and conditions of this Agreement and the other Loan Documents, and in reliance upon the representations and warranties of the Borrower set forth herein and in the other Loan Documents, the Bank agrees to make such Revolving Loans at such times as the Borrower may from time to time request until, but not including, the Revolving Loan Maturity Date, and in such amounts as the Borrower may from time to time request, provided, however, that the aggregate principal balance of all Revolving Loans outstanding at any time shall not exceed the Revolving Loan Availability. Revolving Loans made by the Bank may be repaid and, subject to the terms and conditions hereof, borrowed again up to, but not including the Revolving Loan Maturity Date unless the Revolving Loans are otherwise accelerated, terminated or extended as provided in this Agreement. The Revolving Loans shall be used by the Borrower for the purpose of working capital and general corporate purposes.

(b)   Revolving Loan Interest and Payments. Except as otherwise provided in this Section 2.1(b), the principal amount of the Revolving Loans outstanding from time to time shall bear interest at the applicable Revolving Interest Rate. Accrued and unpaid interest on the unpaid principal balance of all Revolving Loans outstanding from time to time which are Base Rate Loans, shall be due and payable on the last Business Day of each month. Accrued and unpaid interest on the unpaid principal balance of all Revolving Loans outstanding from time to time which are LIBOR Loans shall be payable on the last Business Day of each Interest Period, commencing on the first such date to occur after the date hereof, on the date of any principal repayment of a LIBOR Loan and on the Revolving Loan Maturity Date. From and after maturity, or after the occurrence and during the continuation of an Event of Default, interest on the outstanding principal balance of the Revolving Loans, at the option of the Bank, may accrue at the Default Rate and shall be payable upon demand from the Bank.

15

(c)    Revolving Loan Principal Payments.

(i)    Revolving Loan Mandatory Payments. All Revolving Loans hereunder shall be repaid by the Borrower on the Revolving Loan Maturity Date, unless payable sooner pursuant to the provisions of this Agreement. In the event the aggregate outstanding principal balance of all Revolving Loans and Letter of Credit Obligations hereunder exceeds the Revolving Loan Availability, the Borrower shall, without notice or demand of any kind, immediately make such repayments of the Revolving Loans or take such other actions as are satisfactory to the Bank as shall be necessary to eliminate such excess.

(ii)   Optional Prepayments. The Borrower may from time to time prepay the Revolving Loans which are Base Rate Loans, in whole or in part, without any prepayment penalty whatsoever, provided that any prepayment of the entire principal balance of the Base Rate Loans shall include accrued interest on such Base Rate Loans to the date of such prepayment.

2.2.   Additional LIBOR Loan Provisions.

(a)    LIBOR Loan Prepayments. Notwithstanding anything to the contrary contained herein, the principal balance of any LIBOR Loan may not be prepaid in whole or in part at any time. If, for any reason, a LIBOR Loan is paid prior to the last Business Day of any Interest Period, whether voluntary, involuntary, by reason of acceleration or otherwise, each such prepayment of a LIBOR Loan will be accompanied by the amount of accrued interest on the amount prepaid and any and all costs, expenses, penalties and charges incurred by the Bank as a result of the early termination or breakage of a LIBOR Loan, plus the amount, if any, by which (i) the additional interest which would have been payable during the Interest Period on the LIBOR Loan prepaid had it not been prepaid, exceeds (ii) the interest which would have been recoverable by the Bank by placing the amount prepaid on deposit in the domestic certificate of deposit market, the eurodollar deposit market, or other appropriate money market selected by the Bank, for a period starting on the date on which it was prepaid and ending on the last day of the Interest Period for such LIBOR Loan. The amount of any such loss or expense payable by the Borrower to the Bank under this section shall be determined in the Bank’s sole discretion based upon the assumption that the Bank funded its loan commitment for LIBOR Loans in the London Interbank Eurodollar market and using any reasonable attribution or averaging methods which the Bank deems appropriate and practical, provided, however, that the Bank is not obligated to accept a deposit in the London Interbank Eurodollar market in order to charge interest on a LIBOR Loan at the LIBOR Rate.

(b)    LIBOR Unavailability. If the Bank determines in good faith (which determination shall be conclusive, absent manifest error) prior to the commencement of any Interest Period that (i) the making or maintenance of any LIBOR Loan would violate any applicable law, rule, regulation or directive, whether or not having the force of law, (ii) United States dollar deposits in the principal amount, and for periods equal to the Interest Period for funding any LIBOR Loan are not available in the London Interbank Eurodollar market in the ordinary course of business, (iii) by reason of circumstances affecting the London Interbank Eurodollar market, adequate and fair means do not exist for ascertaining the LIBOR Rate to be applicable to the relevant LIBOR Loan, or (iv) the LIBOR Rate does not accurately reflect the cost to the Bank of a LIBOR Loan, the Bank shall promptly notify the Borrower thereof and, so long as the foregoing conditions continue, none of the Loans may be advanced as a LIBOR Loan thereafter. In addition, at the Borrower’s option, each existing LIBOR Loan shall be immediately (i) converted to a Base Rate Loan on the last Business Day of the then existing Interest Period, or (ii) due and payable on the last Business Day of the then existing Interest Period, without further demand, presentment, protest or notice of any kind, all of which are hereby waived by the Borrower.

16

(c)    Regulatory Change. In addition, if, after the date hereof, a Regulatory Change shall, in the reasonable determination of the Bank, make it unlawful for the Bank to make or maintain the LIBOR Loans, then the Bank shall promptly notify the Borrower and none of the Loans may be advanced as a LIBOR Loan thereafter. In addition, at the Borrower’s option, each existing LIBOR Loan shall be immediately (i) converted to a Base Rate Loan on the last Business Day of the then existing Interest Period or on such earlier date as required by law, or (ii) due and payable on the last Business Day of the then existing Interest Period or on such earlier date as required by law, all without further demand, presentment, protest or notice of any kind, all of which are hereby waived by the Borrower.

(d)    LIBOR Indemnity. If any Regulatory Change, or compliance by the Bank or any Person controlling the Bank with any request or directive of any governmental authority, central bank or comparable agency (whether or not having the force of law) shall (a) impose, modify or deem applicable any assessment, 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, the Bank; (b) subject the Bank or any LIBOR Loan to any tax, duty, charge, stamp tax or fee or change the basis of taxation of payments to the Bank of principal or interest due from the Borrower to the Bank hereunder (other than a change in the taxation of the overall net income of the Bank); or (c) impose on the Bank any other condition regarding such LIBOR Loan or the Bank’s funding thereof, and the Bank shall determine (which determination shall be conclusive, absent manifest error) that the result of the foregoing is to increase the cost to, or to impose a cost on, the Bank or such controlling Person of making or maintaining such LIBOR Loan or to reduce the amount of principal or interest received by the Bank hereunder, then the Borrower shall pay to the Bank or such controlling Person, on demand, such additional amounts as the Bank shall, from time to time, determine are sufficient to compensate and indemnify the Bank for such increased cost or reduced amount.

2.4   Interest and Fee Computation; Collection of Funds. Except as otherwise set forth herein, all interest and fees shall be calculated on the basis of a year consisting of 360 days and shall be paid for the actual number of days elapsed. Principal payments submitted in funds not immediately available shall continue to bear interest until collected. If any payment to be made by the Borrower hereunder or under any Note shall become due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day and such extension of time shall be included in computing any interest in respect of such payment. Notwithstanding anything to the contrary contained herein, the final payment due under any of the Loans must be made by wire transfer or other immediately available funds. All payments made by the Borrower hereunder or under any of the Loan Documents shall be made without setoff, counterclaim, or other defense. To the extent permitted by applicable law, all payments hereunder or under any of the Loan Documents (including any payment of principal, interest, or fees) to, or for the benefit, of any Person shall be made by the Borrower free and clear of, and without deduction or withholding for, or account of, any taxes now or hereinafter imposed by any taxing authority.   The Borrower pay the Bank a Non- Utilization Fee as per the Applicable Margin, which Non-U tilization Fee shall be (A) calculated on the basis of a year consisting of 360 days, (B) paid for the actual number of days elapsed, and (C) payable quarterly in arrears on the last day of each March, June, September and December, commencing on March 31, 2007, and on the Revolving Loan Maturity Date. Issued but undrawn Letters of Credit will count as utilization for the purposes of calculating the Non-Utilization Fee.

17

2.5.   Letters of Credit. Subject to the terms and conditions of this Agreement and upon (i) the execution by the Borrower and the Bank of a Master Letter of Credit Agreement in form and substance acceptable to the Bank (together with all amendments, modifications and restatements thereof, the “Master Letter of Credit Agreement”), and (ii) the execution and delivery by the Borrower, and the acceptance by the Bank, in its sole and absolute discretion, of a Letter of Credit Application, the Bank agrees to issue for the account of the Borrower such Letters of Credit in the standard form of the Bank and otherwise in form and substance acceptable to the Bank, from time to time during the term of this Agreement, provided that the Letter of Credit Obligations may not at any time exceed the Letter of Credit Commitment and provided further, that no Letter of Credit shall have an expiration date later than the Letter of Credit Maturity Date. The amount of any payments made by the Bank with respect to draws made by a beneficiary under a Letter of Credit for which the Borrower has failed to reimburse the Bank upon the earlier of (i) the Bank’s demand for repayment, or (ii) five (5) days from the date of such payment to such beneficiary by the Bank, shall be deemed to have been converted to a Revolving Loan as of the date such payment was made by the Bank to such beneficiary. Upon the occurrence of an Event of a Default and at the option of the Bank, all Letter of Credit Obligations shall be converted to Revolving Loans consisting of Base Rate Loans, all without demand, presentment, protest or notice of any kind, all of which are hereby waived by the Borrower. To the extent the provisions of the Master Letter of Credit Agreement differ from, or are inconsistent with, the terms of this Agreement, the provisions of this Agreement shall govern. The Borrower shall pay the Bank a Letter of Credit Fee as per the Applicable Margin.

2.6.   Taxes.

(a)    All payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any governmental authority, excluding net income taxes and franchise taxes (imposed in lieu of net income taxes) imposed on the Bank as a result of a present or former connection between the Bank and the jurisdiction of the governmental authority imposing such tax or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from the Bank having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any other Loan Document). If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (collectively, “Non-Excluded Taxes”) or Other Taxes are required to be withheld from any amounts payable to the Bank hereunder, the amounts so payable to the Bank shall be increased to the extent necessary to yield to the Bank (after payment of all Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement, provided, however, that the Borrower shall not be required to increase any such amounts payable to the Bank with respect to any Non-Excluded Taxes that are attributable to the Bank’s failure to comply with the requirements of subsection 2.7(c).

18

(b)    The Borrower shall pay any Other Taxes to the relevant governmental authority in accordance with applicable law.

(c)    At the request of the Borrower and at the Borrower’s sole cost, the Bank shall take reasonable steps to (i) contest its liability for any Non-Excluded Taxes or Other Taxes that have not been paid, or (ii) seek a refund of any Non-Excluded Taxes or Other Taxes that have been paid.

(d)    Whenever any Non-Excluded Taxes or Other Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the Bank a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority or fails to remit to the Bank the required receipts or other required documentary evidence or if any governmental authority seeks to collect a Non-Excluded Tax or Other Tax directly from the Bank for any other reason, the Borrower shall indemnify the Bank on an after-tax basis for any incremental taxes, interest or penalties that may become payable by the Bank.

(e)    The agreements in this Section shall survive the satisfaction and payment of the Obligations and the termination of this Agreement.

2.7.   All Loans to Constitute Single Obligation. The Loans shall constitute one general obligation of the Borrower, and shall be secured by Bank’s priority security interest in and Lien upon all of the Collateral and by all other security interests, Liens, claims and encumbrances heretofore, now or at any time or times hereafter granted by the Borrower and/or any Subsidiary to Bank.

Section 5.   MANNER OF BORROWING.

5.1.   Borrowing Procedures. Each Revolving Loan   may be advanced either as a Base Rate Loan or a LIBOR Loan. Each Loan shall be made available to the Borrower upon any written, verbal, electronic, telephonic or telecopy loan request which the Bank in good faith believes to emanate from a properly authorized representative of the Borrower, whether or not that is in fact the case. Each such request shall be effective upon receipt by the Bank, shall be irrevocable, and shall specify the date, amount and type of borrowing and, in the case of a LIBOR Loan, the initial Interest Period therefor. The Borrower shall select Interest Periods so as not to require a payment or prepayment of any LIBOR Loan during an Interest Period for such LIBOR Loan. The final Interest Period must be such that its expiration occurs on or before the Revolving Loan Maturity Date. A request for a Base Rate Loan must be received by the Bank no later than 12:00 p.m. Chicago, Illinois   time, on the day it is to be funded. A request for a LIBOR Loan must be (i) received by the Bank no later than 12:00 p.m. Chicago, Illinois time, three days before the day it is to be funded, and (ii) in an amount equal to One Hundred Thousand and 00/100 Dollars ($100,000.00) or a higher integral multiple of One Hundred Thousand and 00/100 Dollars ($100,000.00). The proceeds of each Loan shall be made available at the office of the Bank by credit to the account of the Borrower or by other means requested by the Borrower and acceptable to the Bank. The Borrower does hereby irrevocably confirm, ratify and approve all such advances by the Bank and does hereby indemnify the Bank against losses and expenses (including court costs, attorneys’ and paralegals’ fees) and shall hold the Bank harmless with respect thereto.

5.2.   LIBOR Conversion and Continuation Procedures. Each LIBOR Loan shall automatically renew for the Interest Period specified in the initial request received by the Bank pursuant to Section 5.1, at the then current LIBOR Rate unless the Borrower, pursuant to a subsequent written notice received by the Bank, shall elect a different Interest Period or the conversion of all or a portion of such LIBOR Loan to a Base Rate Loan. Each Interest Period occurring after the initial Interest Period with respect to any LIBOR Loan shall commence on the same day of each applicable month as the first day of the initial Interest Period. Whenever the last day of any Interest Period with respect to any LIBOR Loan would otherwise occur on a day other than a Business Day, the last day of such Interest Period shall be extended to occur on the next succeeding Business Day. Whenever an Interest Period with respect to any LIBOR Loan would otherwise end on a day of a month for which there is no numerically corresponding day in the calendar month, such Interest Period shall end on the last day of such calendar month, unless such day is not a Business Day, in which event such Interest Period shall be extended to end on the next Business Day.   Upon receipt by the Bank of such subsequent notice, the Borrower may, subject to the terms and conditions of this Agreement, elect, as of the last day of the applicable Interest Period, to continue any LIBOR Loan having an Interest Period expiring on such day for a different Interest Period, or to convert any such LIBOR Loan to a Base Rate Loan. Such notice shall, in the case of a conversion to a Base Rate Loan, be given before 12:00 p.m., Chicago time, on the proposed date of such conversion, and in the case of conversion to a LIBOR Loan having a different Interest Period, be given before 12:00 p.m., Chicago time, at least three Business Days prior to the proposed date of such conversion, specifying: (i) the proposed date of conversion; (ii) the aggregate amount of Loans to be converted; (iii) the type of Loans resulting from the proposed conversion; and (iv) the duration of the requested Interest Period. The Borrower may not elect a LIBOR Rate, and an Interest Period for a LIBOR Loan shall not automatically renew, with respect to any principal amount which is scheduled to be repaid before the last day of the applicable Interest Period, and any such amounts shall bear interest at the Base Rate Rate plus Applicable Margin.

23

5.3.   Letters of Credit. All Letters of Credit shall bear such application, issuance, renewal, negotiation and other fees and charges, and bear such interest as charged by the Bank or otherwise payable pursuant to the Master Letter of Credit Agreement. In addition to the foregoing, each standby Letters of Credit issued under and pursuant to this Agreement shall bear an annual issuance fee equal to the LIBOR spread of the Applicable Margin based on   the face amount of such standby Letter of Credit, payable by the Borrower prior to the issuance by the Bank of such Letter of Credit and annually thereafter, until (i) such Letter of Credit has expired or has been returned to the Bank, or (ii) the Bank has paid the beneficiary thereunder the full face amount of such Letter of Credit.

5.4.   Automatic Debit. In order to effectuate the timely payment of any of the Obligations when due, the Borrower hereby authorizes and directs the Bank, at the Bank’s option, to (a) debit the amount of the Obligations to any ordinary deposit account of the Borrower, or (b) make a Revolving Loan hereunder to pay the amount of the Obligations.

5.5.   Discretionary Disbursements. The Bank, in its sole and absolute discretion, may immediately upon notice to the Borrower, disburse any or all proceeds of the Loans made or available to the Borrower pursuant to this Agreement to pay any fees, costs, expenses or other amounts required to be paid by the Borrower hereunder and not so paid. All monies so disbursed shall be a part of the Obligations, payable by the Borrower on demand from the Bank.

The Bank agrees with the Borrower that the Bank will arrange, pursuant to procedures satisfactory to the Bank and so long as such procedures will not result in the Bank’s loss of control, for the Borrower to make alterations to the electronic chattel paper or transferable record permitted under Section 9-105 of the UCC or, as the case may be, Section 201 of the federal Electronic Signatures in Global and National Commerce Act or Section 16 of the Uniform Electronic Transactions Act for a party in control to make without loss of control.

Upon the occurrence of an Event of Default, the Bank shall have all rights, powers and remedies set forth in the Loan Documents, in any written agreement or instrument (other than this Agreement or the Loan Documents) relating to any of the Obligations or any security therefor, as a secured party under the UCC or as otherwise provided at law or in equity. Without limiting the generality of the foregoing, the Bank may, at its option upon the occurrence of an Event of Default, declare its commitments to the Borrower to be terminated and all Obligations to be immediately due and payable, provided, however, that upon the occurrence of an Event of Default under Section 11.7, all commitments of the Bank to the Borrower shall immediately terminate and all Obligations shall be automatically due and payable, all without demand, notice or further action of any kind required on the part of the Bank. The Borrower hereby waives any and all presentment, demand, notice of dishonor, protest, and all other notices and demands in connection with the enforcement of Bank’s rights under the Loan Documents, and hereby consents to, and waives notice of release, with or without consideration, of any of the Borrower or any of the Guarantors or of any Collateral, notwithstanding anything contained herein or in the Loan Documents to the contrary. In addition to the foregoing:

12.1.   Possession and Assembly of Collateral. The Bank may, without notice, demand or legal process of any kind, take possession of any or all of the Collateral (in addition to Collateral of which the Bank already has possession), wherever it may be found, and for that purpose may pursue the same wherever it may be found, and may at any time enter into any of the Borrower’s premises where any of the Collateral may be or is supposed to be, and search for, take possession of, remove, keep and store any of the Collateral until the same shall be sold or otherwise disposed of and the Bank shall have the right to store and conduct a sale of the same in any of the Borrower’s premises without cost to the Bank. At the Bank’s request, the Borrower will, at the Borrower’s sole expense, assemble the Collateral and make it available to the Bank at a place or places to be designated by the Bank which is reasonably convenient to the Bank and the Borrower.

12.2.   Sale of Collateral. The Bank may sell any or all of the Collateral at public or private sale, upon such terms and conditions as the Bank may deem proper, and the Bank may purchase any or all of the Collateral at any such sale. The Borrower acknowledges that the Bank may be unable to effect a public sale of all or any portion of the Collateral because of certain legal and/or practical restrictions and provisions which may be applicable to the Collateral and, therefore, may be compelled to resort to one or more private sales to a restricted group of offerees and purchasers. The Borrower consents to any such private sale so made even though at places and upon terms less favorable than if the Collateral were sold at public sale. The Bank shall have no obligation to clean-up or otherwise prepare the Collateral for sale. The Bank may apply the net proceeds, after deducting all costs, expenses, attorneys’ and paralegals’ fees incurred or paid at any time in the collection, protection and sale of the Collateral and the Obligations, to the payment of any Note and/or any of the other Obligations, returning the excess proceeds, if any, to the Borrower. The Borrower shall remain liable for any amount remaining unpaid after such application, with interest at the Default Rate. Any notification of intended disposition of the Collateral required by law shall be conclusively deemed reasonably and properly given if given by the Bank at least ten (10) calendar days before the date of such disposition. The Borrower hereby confirms, approves and ratifies all acts and deeds of the Bank relating to the foregoing, and each part thereof, and expressly waives any and all claims of any nature, kind or description which it has or may hereafter have against the Bank or its representatives, by reason of taking, selling or collecting any portion of the Collateral. The Borrower consents to releases of the Collateral at any time (including prior to default) and to sales of the Collateral in groups, parcels or portions, or as an entirety, as the Bank shall deem appropriate. The Borrower expressly absolves the Bank from any loss or decline in market value of any Collateral by reason of delay in the enforcement or assertion or nonenforcement of any rights or remedies under this Agreement.

48

12.3.   Standards for Exercising Remedies.   To the extent that applicable law imposes duties on the Bank to exercise remedies in a commercially reasonable manner, the Borrower acknowledges and agrees that it is not commercially unreasonable for the Bank (a) to fail to incur expenses reasonably deemed significant by the Bank to prepare Collateral for disposition or otherwise to complete raw material or work-in-process into finished goods or other finished products for disposition, (b) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (c) to fail to exercise collection remedies against Account Debtors or other Persons obligated on Collateral or to remove liens or encumbrances on or any adverse claims against Collateral, (d) to exercise collection remedies against Account Debtors and other Persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (e) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (f) to contact other Persons, whether or not in the same business as the Borrower, for expressions of interest in acquiring all or any portion of the Collateral, (g) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the collateral is of a specialized nature, (h) to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers of assets, (i) to dispose of assets in wholesale rather than retail markets, (j) to disclaim disposition warranties, including any warranties of title, (k) to purchase insurance or credit enhancements to insure the Bank against risks of loss, collection or disposition of Collateral or to provide to the Bank a guaranteed return from the collection or disposition of Collateral, or (l) to the extent deemed appropriate by the Bank, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist the Bank in the collection or disposition of any of the Collateral. The Borrower acknowledges that the purpose of this section is to provide non-exhaustive indications of what actions or omissions by the Bank would not be commercially unreasonable in the Bank’s exercise of remedies against the Collateral and that other actions or omissions by the Bank shall not be deemed commercially unreasonable solely on account of not being indicated in this section. Without limitation upon the foregoing, nothing contained in this section shall be construed to grant any rights to the Borrower or to impose any duties on the Bank that would not have been granted or imposed by this Agreement or by applicable law in the absence of this section.

12.4.   UCC and Offset Rights. The Bank may exercise, from time to time, any and all rights and remedies available to it under the UCC or under any other applicable law in addition to, and not in lieu of, any rights and remedies expressly granted in this Agreement or in any other agreements between any Obligor and the Bank, and may, without demand or notice of any kind, appropriate and apply toward the payment of such of the Obligations, whether matured or unmatured, including costs of collection and attorneys’ and paralegals’ fees, and in such order of application as the Bank may, from time to time, elect, any indebtedness of the Bank to any Obligor, however created or arising, including balances, credits, deposits, accounts or moneys of such Obligor in the possession, control or custody of, or in transit to the Bank. The Borrower, on behalf of itself and each Obligor, hereby waives the benefit of any law that would otherwise restrict or limit the Bank in the exercise of its right, which is hereby acknowledged, to appropriate at any time hereafter any such indebtedness owing from the Bank to any Obligor.

49

12.5.   Additional Remedies. The Bank shall have the right and power to:

(a)    instruct the Borrower, at its own expense, to notify any parties obligated on any of the Collateral, including any Account Debtors, to make payment directly to the Bank of any amounts due or to become due thereunder, or the Bank may directly notify such obligors of the security interest of the Bank, and/or of the assignment to the Bank of the Collateral and direct such obligors to make payment to the Bank of any amounts due or to become due with respect thereto, and thereafter, collect any such amounts due on the Collateral directly from such Persons obligated thereon;

(b)   enforce collection of any of the Collateral, including any Accounts, by suit or otherwise, or make any compromise or settlement with respect to any of the Collateral, or surrender, release or exchange all or any part thereof, or compromise, extend or renew for any period (whether or not longer than the original period) any indebtedness thereunder;

(c)    take possession or control of any proceeds and products of any of the Collateral, including the proceeds of insurance thereon;

(d)   extend, renew or modify for one or more periods (whether or not longer than the original period) any Note, any other of the Obligations, any obligation of any nature of any other obligor with respect to any Note or any of the Obligations;

(e)    grant releases, compromises or indulgences with respect to any Note, any of the Obligations, any extension or renewal of any of the Obligations, any security therefor, or to any other obligor with respect to any Note or any of the Obligations;

(f)    transfer the whole or any part of securities which may constitute Collateral into the name of the Bank or the Bank’s nominee without disclosing, if the Bank so desires, that such securities so transferred are subject to the security interest of the Bank, and any corporation, association, or any of the managers or trustees of any trust issuing any of such securities, or any transfer agent, shall not be bound to inquire, in the event that the Bank or such nominee makes any further transfer of such securities, or any portion thereof, as to whether the Bank or such nominee has the right to make such further transfer, and shall not be liable for transferring the same;

50

(g)    vote the Collateral;

(h)   make an election with respect to the Collateral under Section 1111 of the Bankruptcy Code or take action under Section 364 or any other section of the Bankruptcy Code; provided, however, that any such action of the Bank as set forth herein shall not, in any manner whatsoever, impair or affect the liability of the Borrower hereunder, nor prejudice, waive, nor be construed to impair, affect, prejudice or waive the Bank’s rights and remedies at law, in equity or by statute, nor release, discharge, nor be construed to release or discharge, the Borrower, any guarantor or other Person liable to the Bank for the Obligations;

(i)    at any time, and from time to time, accept additions to, releases, reductions, exchanges or substitution of the Collateral, without in any way altering, impairing, diminishing or affecting the provisions of this Agreement, the Loan Documents, or any of the other Obligations, or the Bank’s rights hereunder, under any Note or under any of the other Obligations; and

(j)     advise the Borrower whether to deposit cash as necessary into the Borrower’s account at the Bank or whether to execute, within ten business days of such Event of Default or Unmatured Event of Default, Control Agreements(s) with respect to Cash Equivalent Investments.

The Borrower hereby ratifies and confirms whatever the Bank may do with respect to the Collateral and agrees that the Bank shall not be liable for any error of judgment or mistakes of fact or law with respect to actions taken in connection with the Collateral.

12.6.   Attorney-in-Fact. Upon the occurrence and during the continuation of an Event of Default, the Borrower hereby irrevocably makes, constitutes and appoints the Bank (and any officer of the Bank or any Person designated by the Bank for that purpose) as the Borrower’s true and lawful proxy and attorney-in-fact (and agent-in-fact) in the Borrower’s name, place and stead, with full power of substitution, to (i) take such actions as are permitted in this Agreement, (ii) execute such financing statements and other documents and to do such other acts as the Bank may require to perfect and preserve the Bank’s security interest in, and to enforce such interests in the Collateral, and (iii) carry out any remedy provided for in this Agreement, including endorsing the Borrower’s name to checks, drafts, instruments and other items of payment, and proceeds of the Collateral, executing change of address forms with the postmaster of the United States Post Office serving the address of the Borrower, changing the address of the Borrower to that of the Bank, opening all envelopes addressed to the Borrower and applying any payments contained therein to the Obligations. The Borrower hereby acknowledges that the constitution and appointment of such proxy and attorney-in-fact are coupled with an interest and are irrevocable. The Borrower hereby ratifies and confirms all that such attorney-in-fact may do or cause to be done by virtue of any provision of this Agreement.

12.7.   No Marshaling. The Bank shall not be required to marshal any present or future collateral security (including this Agreement and the Collateral) for, or other assurances of payment of, the Obligations or any of them or to resort to such collateral security or other assurances of payment in any particular order. To the extent that it lawfully may, the Borrower hereby agrees that it will not invoke any law relating to the marshaling of collateral which might cause delay in or impede the enforcement of the Bank’s rights under this Agreement or under any other instrument creating or evidencing any of the Obligations or under which any of the Obligations is outstanding or by which any of the Obligations is secured or payment thereof is otherwise assured, and, to the extent that it lawfully may, the Borrower hereby irrevocably waives the benefits of all such laws.

51

12.8.   Application of Proceeds. The Bank will within three (3) Business Days after receipt of cash or solvent credits from collection of items of payment, proceeds of Collateral or any other source, apply the whole or any part thereof against the Obligations secured hereby. The Bank shall further have the exclusive right to determine how, when and what application of such payments and such credits shall be made on the Obligations, and such determination shall be conclusive upon the Borrower. Any proceeds of any disposition by the Bank of all or any part of the Collateral may be first applied by the Bank to the payment of expenses incurred by the Bank in connection with the Collateral, including attorneys’ fees and legal expenses as provided for in Section 13 hereof.

12.9.   No Waiver. No Event of Default shall be waived by the Bank except in writing. No failure or delay on the part of the Bank in exercising any right, power or remedy hereunder shall operate as a waiver of the exercise of the same or any other right at any other time; nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. There shall be no obligation on the part of the Bank to exercise any remedy available to the Bank in any order. The remedies provided for herein are cumulative and not exclusive of any remedies provided at law or in equity. The Borrower agrees that in the event that the Borrower fails to perform, observe or discharge any of its Obligations or liabilities under this Agreement or any other agreements with the Bank, no remedy of law will provide adequate relief to the Bank, and further agrees that the Bank shall be entitled to temporary and permanent injunctive relief in any such case without the necessity of proving actual damages.

12.10.   Letters of Credit. With respect to all Letters of Credit for which presentment for honor shall not have occurred at the time of an acceleration pursuant to this Section 12, the Borrower shall at such time deposit in a cash collateral account opened by the Bank an amount equal to the Letter of Credit Obligations then outstanding. Amounts held in such cash collateral account shall be applied by the Bank to the payment of drafts drawn under such Letters of Credit, and the unused portion thereof after all such Letters of Credit shall have expired or been fully drawn upon, if any, shall be applied to repay the Obligations, in such order of application as the Bank may, in its sole discretion, from time to time elect. After all such Letters of Credit shall have expired or been fully drawn upon, all commitments to make Loans hereunder have terminated and all other Obligations have been indefeasibly satisfied and paid in full in cash, the balance, if any, in such cash collateral account shall be returned to the Borrower or such other Person as may be lawfully entitled thereto.

52

Section 13.   MISCELLANEOUS.

13.1.   Obligations Absolute. None of the following shall affect the Obligations of the Borrower to the Bank under this Agreement or the Bank’s rights with respect to the Collateral:

(a)    acceptance or retention by the Bank of other property or any interest in property as security for the Obligations;

(b)    release by the Bank of any of the Borrower or the Guarantors or of all or any part of the Collateral or of any party liable with respect to the Obligations;

(c)    release, extension, renewal, modification or substitution by the Bank of any Note, or any note evidencing any of the Obligations, or the compromise of the liability of any of the Guarantors of the Obligations; or

(d)    failure of the Bank to resort to any other security or to pursue the Borrower or any other obligor liable for any of the Obligations before resorting to remedies against the Collateral.

13.2.   Entire Agreement. This Agreement and the other Loan Documents (i) are valid, binding and enforceable against the Borrower and the Bank in accordance with their respective provisions and no conditions exist as to their legal effectiveness; (ii) constitute the entire agreement between the parties with respect to the subject matter hereof and thereof; and (iii) are the final expression of the intentions of the Borrower and the Bank. No promises, either expressed or implied, exist between the Borrower and the Bank, unless contained herein or therein. This Agreement, together with the other Loan Documents, supersedes all negotiations, representations, warranties, commitments, term sheets, discussions, negotiations, offers or contracts (of any kind or nature, whether oral or written) prior to or contemporaneous with the execution hereof with respect to any matter, directly or indirectly related to the terms of this Agreement and the other Loan Documents. This Agreement and the other Loan Documents are the result of negotiations among the Bank, the Borrower and the other parties thereto, and have been reviewed (or have had the opportunity to be reviewed) by counsel to all such parties, and are the products of all parties. Accordingly, this Agreement and the other Loan Documents shall not be construed more strictly against the Bank merely because of the Bank’s involvement in their preparation.

13.3.   Amendments; Waivers. No delay on the part of the Bank in the exercise of any right, power or remedy shall operate as a waiver thereof, nor shall any single or partial exercise by the Bank of any right, power or remedy preclude other or further exercise thereof, or the exercise of any other right, power or remedy. No amendment, modification or waiver of, or consent with respect to, any provision of this Agreement or the other Loan Documents shall in any event be effective unless the same shall be in writing and acknowledged by the Bank, and then any such amendment, modification, waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

53

13.4.   WAIVER OF DEFENSES. THE BORROWER, ON BEHALF OF ITSELF AND ANY GUARANTOR OF ANY OF THE OBLIGATIONS, WAIVES EVERY PRESENT AND FUTURE DEFENSE, CAUSE OF ACTION, COUNTERCLAIM OR SETOFF WHICH THE BORROWER MAY NOW HAVE OR HEREAFTER MAY HAVE TO ANY ACTION BY THE BANK IN ENFORCING THIS AGREEMENT. PROVIDED THE BANK ACTS IN GOOD FAITH, THE BORROWER RATIFIES AND CONFIRMS WHATEVER THE BANK MAY DO PURSUANT TO THE TERMS OF THIS AGREEMENT. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE BANK GRANTING ANY FINANCIAL ACCOMMODATION TO THE BORROWER.

13.5.   FORUM SELECTION AND CONSENT TO JURISDICTION. ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS OF THE STATE OF ILLINOIS OR IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS; PROVIDED THAT NOTHING IN THIS AGREEMENT SHALL BE DEEMED OR OPERATE TO PRECLUDE THE BANK FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION. THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS TO THE JURISDICTION OF THE COURTS OF THE STATE OF ILLINOIS AND OF THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE. THE BORROWER FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF ILLINOIS. THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

13.6.   WAIVER OF JURY TRIAL. THE BANK AND THE BORROWER, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT WITH COUNSEL, EACH KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE IRREVOCABLY, ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS AGREEMENT, ANY NOTE, ANY OTHER LOAN DOCUMENT, ANY OF THE OTHER OBLIGATIONS, THE COLLATERAL, OR ANY AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR WHICH MAY IN THE FUTURE BE DELIVERED IN CONNECTION HEREWITH OR THEREWITH OR ARISING FROM ANY LENDING RELATIONSHIP EXISTING IN CONNECTION WITH ANY OF THE FOREGOING, OR ANY COURSE OF CONDUCT OR COURSE OF DEALING IN WHICH THE BANK AND THE BORROWER ARE ADVERSE PARTIES, AND EACH AGREES THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE BANK GRANTING ANY FINANCIAL ACCOMMODATION TO THE BORROWER.

54

13.7.   Assignability. The Bank may at any time assign the Bank’s rights in this Agreement, the other Loan Documents, the Obligations, or any part thereof and transfer the Bank’s rights in any or all of the Collateral, and the Bank thereafter shall be relieved from all liability with respect to such Collateral; provided, however, that if an Event of Default does not exist, the Bank shall not make such assignment without the prior written consent of the Borrower. In addition, the Bank may at any time sell one or more participations in the Loans. The Borrower may not sell or assign this Agreement, or any other agreement with the Bank or any portion thereof, either voluntarily or by operation of law, without the prior written consent of the Bank. This Agreement shall be binding upon the Bank and the Borrower and their respective legal representatives and successors. All references herein to the Borrower shall be deemed to include any successors, whether immediate or remote. In the case of a joint venture or partnership, the term “Borrower” shall be deemed to include all joint venturers or partners thereof, who shall be jointly and severally liable hereunder.

13.8.   Confirmations. The Borrower and the Bank agree from time to time, upon written request received by it from the other, to confirm to the other in writing the aggregate unpaid principal amount of the Loans then outstanding under such Note.

13.9.   Confidentiality. The Bank agrees to use commercially reasonable efforts (equivalent to the efforts the Bank applies to maintain the confidentiality of its own confidential information) to maintain as confidential all information provided to it by the Borrower, including all information designated as confidential, except that the Bank may disclose such information (a) to Persons employed or engaged by the Bank in evaluating, approving, structuring or administering the Loans; (b) to any assignee or participant or potential assignee or participant that has agreed to comply with the covenant contained in this Section 13.9 (and any such assignee or participant or potential assignee or participant may disclose such information to Persons employed or engaged by them as described in clause (a) above); (c) as required or requested by any federal or state regulatory authority or examiner, or any insurance industry association, or as reasonably believed by the Bank to be compelled by any court decree, subpoena or legal or administrative order or process; (d) as, on the advice of the Bank’s counsel, is required by law; (e) in connection with the exercise of any right or remedy under the Loan Documents or in connection with any litigation to which the Bank is a party; (f) to any nationally recognized rating agency that requires access to information about the Bank’s investment portfolio in connection with ratings issued with respect to the Bank; (g) to any Affiliate of the Bank who may provide Bank Products to the Borrower or any Subsidiary, or (h) that ceases to be confidential through no fault of the Bank.

13.10.   Binding Effect. This Agreement shall become effective upon execution by the Borrower and the Bank. If this Agreement is not dated or contains any blanks when executed by the Borrower, the Bank is hereby authorized, without notice to the Borrower, to date this Agreement as of the date when it was executed by the Borrower, and to complete any such blanks according to the terms upon which this Agreement is executed.

55

13.11.   Governing Law. This Agreement, the Loan Documents and any Note shall be delivered and accepted in and shall be deemed to be contracts made under and governed by the internal laws of the State of Illinois (but giving effect to federal laws applicable to national banks) applicable to contracts made and to be performed entirely within such state, without regard to conflict of laws principles.

13.12.   Enforceability. Wherever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be prohibited by, unenforceable or invalid under any jurisdiction, such provision shall as to such jurisdiction, be severable and be ineffective to the extent of such prohibition or invalidity, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction.

13.13.   Survival of Borrower Representations. All covenants, agreements, representations and warranties made by the Borrower herein shall, notwithstanding any investigation by the Bank, be deemed material and relied upon by the Bank and shall survive the making and execution of this Agreement and the Loan Documents and the issuance of any Note, and shall be deemed to be continuing representations and warranties until such time as the Borrower has fulfilled all of its Obligations to the Bank, and the Bank has been indefeasibly paid in full in cash. The Bank, in extending financial accommodations to the Borrower, is expressly acting and relying on the aforesaid representations and warranties.

13.14.   Extensions of Bank’s Commitment. This Agreement shall secure and govern the terms of (i) any extensions or renewals of the Bank’s commitment hereunder, and (ii) any replacement note executed by the Borrower and accepted by the Bank in its sole and absolute discretion in substitution for any Note.

13.15.   Time of Essence. Time is of the essence in making payments of all amounts due the Bank under this Agreement and in the performance and observance by the Borrower of each covenant, agreement, provision and term of this Agreement.

13.16.   Counterparts; Facsimile Signatures. This Agreement may be executed in any number of counterparts and by the different parties hereto on separate counterparts and each such counterpart shall be deemed to be an original, but all such counterparts shall together constitute but one and the same Agreement. Receipt of an executed signature page to this Agreement by facsimile or other electronic transmission shall constitute effective delivery thereof. Electronic records of executed Loan Documents maintained by the Bank shall deemed to be originals thereof.

56

13.17.   Notices. Except as otherwise provided herein, the Borrower waives all notices and demands in connection with the enforcement of the Bank’s rights hereunder. All notices, requests, demands and other communications provided for hereunder shall be in writing and addressed as follows:

or, as to each party, at such other address as shall be designated by such party in a written notice to each other party complying as to delivery with the terms of this subsection. All notices addressed as above shall be deemed to have been properly given (i) if served in person, upon acceptance or refusal of delivery; (ii) if mailed by certified or registered mail, return receipt requested, postage prepaid, on the third (3rd) day following the day such notice is deposited in any post office station or letter box; or (iii) if sent by recognized overnight courier, on the first (1st) day following the day such notice is delivered to such carrier. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances.

13.18.   Release of Claims Against Bank. In consideration of the Bank making the Loans, the Borrower and all other Obligors do each hereby release and discharge the Bank of and from any and all claims, harm, injury, and damage of any and every kind, known or unknown, legal or equitable, which any Obligor may have against the Bank from the date of their respective first contact with the Bank until the date of this Loan Agreement, including any claim arising from any reports (environmental reports, surveys, appraisals, etc.) prepared by any parties hired or recommended by the Bank. The Borrower and all other Obligors confirm to Bank that they have reviewed the effect of this release with competent legal counsel of their choice, or have been afforded the opportunity to do so, prior to execution of this Agreement and the Loan Documents and do each acknowledge and agree that the Bank is relying upon this release in extending the Loans to the Borrower.

57

13.19.   Costs, Fees and Expenses. The Borrower shall pay or reimburse the Bank for all reasonable costs, fees and expenses incurred by the Bank or for which the Bank becomes obligated in connection with the negotiation, preparation, consummation, collection of the Obligations or enforcement of this Agreement, the other Loan Documents and all other documents provided for herein or delivered or to be delivered hereunder or in connection herewith (including any amendment, supplement or waiver to any Loan Document),   or during any workout, restructuring or negotiations in respect thereof, including reasonable consultants’ fees and attorneys’ fees and time charges of counsel to the Bank, which shall also include attorneys’ fees and time charges of attorneys who may be employees of the Bank or any Affiliate of the Bank, plus costs and expenses of such attorneys or of the Bank; search fees, costs and expenses; and all taxes payable in connection with this Agreement or the other Loan Documents, whether or not the transaction contemplated hereby shall be consummated. In furtherance of the foregoing, the Borrower shall pay any and all stamp and other taxes, UCC search fees, filing fees and other costs and expenses in connection with the execution and delivery of this Agreement, any Note and the other Loan Documents to be delivered hereunder, and agrees to save and hold the Bank harmless from and against any and all liabilities with respect to or resulting from any delay in paying or omission to pay such costs and expenses. That portion of the Obligations consisting of costs, expenses or advances to be reimbursed by the Borrower to the Bank pursuant to this Agreement or the other Loan Documents which are not paid on or prior to the date hereof shall be payable by the Borrower to the Bank on demand. If at any time or times hereafter the Bank: (a) employs counsel for advice or other representation (i) with respect to this Agreement or the other Loan Documents, (ii) to represent the Bank in any litigation, contest, dispute, suit or proceeding or to commence, defend, or intervene or to take any other action in or with respect to any litigation, contest, dispute, suit, or proceeding (whether instituted by the Bank, the Borrower, or any other Person) in any way or respect relating to this Agreement, the other Loan Documents or the Borrower’s business or affairs, or (iii) to enforce any rights of the Bank against the Borrower or any other Person that may be obligated to the Bank by virtue of this Agreement or the other Loan Documents; (b) takes any action to protect, collect, sell, liquidate, or otherwise dispose of any of the Collateral; and/or (c) attempts to or enforces any of the Bank’s rights or remedies under the Agreement or the other Loan Documents, the costs and expenses incurred by the Bank in any manner or way with respect to the foregoing, shall be part of the Obligations, payable by the Borrower to the Bank on demand.

13.20.   Indemnification. The Borrower agrees to defend (with counsel satisfactory to the Bank), protect, indemnify, exonerate and hold harmless each Indemnified Party from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, expenses and distributions of any kind or nature (including the disbursements and the reasonable fees of counsel for each Indemnified Party thereto, which shall also include, without limitation, reasonable attorneys’ fees and time charges of attorneys who may be employees of any Indemnified Party), which may be imposed on, incurred by, or asserted against, any Indemnified Party (whether direct, indirect or consequential and whether based on any federal, state or local laws or regulations, including securities laws, Environmental Laws, commercial laws and regulations, under common law or in equity, or based on contract or otherwise) in any manner relating to or arising out of this Agreement or any of the Loan Documents, or any act, event or transaction related or attendant thereto, the preparation, execution and delivery of this Agreement and the Loan Documents, including the making or issuance and management of the Loans, the use or intended use of the proceeds of the Loans, the enforcement of the Bank’s rights and remedies under this Agreement, the Loan Documents, any Note, any other instruments and documents delivered hereunder, or under any other agreement between the Borrower and the Bank; provided, however, that the Borrower shall not have any obligations hereunder to any Indemnified Party with respect to matters determined by a court of competent jurisdiction by final and nonappealable judgment to have been   caused by or resulting from the willful misconduct or gross negligence of such Indemnified Party. To the extent that the undertaking to indemnify set forth in the preceding sentence may be unenforceable because it violates any law or public policy, the Borrower shall satisfy such undertaking to the maximum extent permitted by applicable law. Any liability, obligation, loss, damage, penalty, cost or expense covered by this indemnity shall be paid to each Indemnified Party on demand, and failing prompt payment, together with interest thereon at the Default Rate from the date incurred by each Indemnified Party until paid by the Borrower, shall be added to the Obligations of the Borrower and be secured by the Collateral. The provisions of this Section shall survive the satisfaction and payment of the other Obligations and the termination of this Agreement.
