The Lender shall promptly notify the Borrower Representative of its decision as to whether it agrees to make any borrowing requested pursuant to this Section 2.2.2 and in the event the Lender fails to respond or fails to make any requested Loan on the requested borrowing date, Lender shall be assumed to have accepted Borrowers’ request for such Loan.

(B) elect, as of the last day of the applicable Interest Period, to continue any LIBOR Loans having Interest Periods expiring on such day (or any part thereof in an aggregate amount not less than $1,000,000 or a higher integral multiple of $500,000) for a new Interest Period;

provided that after giving effect to any prepayment, conversion or continuation, the aggregate principal amount of each Group of LIBOR Loans shall be at least $1,000,000 and an integral multiple of $500,000.

(b) The Borrower Representative shall give written notice (each such written notice, a “Notice of Conversion/Continuation”) substantially in the form of Exhibit F or telephonic notice (followed immediately by a Notice of Conversion/Continuation) to the Lender of each request for the proposed conversion or continuation not later than (i) in the case of conversion into Base Rate Loans, 2:00 P.M., Chicago time, on the proposed date of such conversion and (ii) in the case of conversion into or continuation of LIBOR Loans, 11:00 A.M., Chicago time, at least three Business Days prior to the proposed date of such conversion or continuation, specifying in each case:

(c) If upon the expiration of any Interest Period applicable to LIBOR Loans, the Borrower Representative has failed to select timely a new Interest Period to be applicable to such LIBOR Loans, the Borrowers shall be deemed to have elected to convert such LIBOR Loans into Base Rate Loans effective on the last day of such Interest Period.

(d) Any conversion of a LIBOR Loan on a day other than the last day of an Interest Period therefor shall be subject to Section 8.4.

(e) The Lender shall promptly notify the Borrower Representative of its decision whether to accept or reject any request for a continuation or conversion pursuant to this Section 2.2.3 and in the event the Lender fails to respond or fails to make any requested conversion or continuation of a Loan on the date requested therefor, Lender shall be assumed to have accepted Borrowers’ request for the same.

2.3.1 L/C Applications. Each Borrower shall execute and deliver to the Lender the Master Letter of Credit Agreement from time to time in effect. The Borrower Representative shall give notice to the Lender of each request for the proposed issuance of each Letter of Credit on a Business Day which is at least three Business Days (or such lesser number of days as the Lender shall agree in any particular instance in its reasonable discretion) prior to the proposed date of issuance of such Letter of Credit. Each such notice shall be accompanied by an L/C Application, duly executed by the Borrowers and in all respects reasonably satisfactory to the Lender, together with such other documentation as the Lender may request in support thereof, it being understood that each L/C Application shall specify, among other things, the date on which the proposed Letter of Credit is to be issued, the expiration date of such Letter of Credit (which shall not be later than the scheduled Termination Date (unless such Letter of Credit is Cash Collateralized)) and whether such Letter of Credit is to be transferable in whole or in part. In the event of any inconsistency between the terms of the Master Letter of Credit Agreement, any L/C Application and the terms of this Agreement, the terms of this Agreement shall control.

(a) The Borrowers hereby unconditionally and irrevocably agree to reimburse the Lender for each payment or disbursement made by the Lender under any Letter of Credit honoring any demand for payment made by the beneficiary thereunder, in each case on the date that such payment or disbursement is made. Any amount not reimbursed on the date of such payment or disbursement shall bear interest from the date of such payment or disbursement to the date that the Lender is reimbursed by the Borrowers

therefor, payable on demand, at a rate per annum equal to the Base Rate from time to time in effect plus the Base Rate Margin from time to time in effect plus, beginning on the third Business Day after receipt of notice from the Lender of such payment or disbursement, 2%. The Lender shall notify the Borrower Representative whenever any demand for payment is made under any Letter of Credit by the beneficiary thereunder; provided that the failure of the Lender to so notify the Borrower Representative shall not affect the rights of the Lender in any manner whatsoever.

(b) The Borrowers’ reimbursement obligations hereunder shall be irrevocable and unconditional under all circumstances, including (a) any lack of validity or enforceability of any Letter of Credit, this Agreement or any other Loan Document, (b) the existence of any claim, set-off, defense or other right which any Loan Party may have at any time against a beneficiary named in a Letter of Credit, any transferee of any Letter of Credit (or any Person for whom any such transferee may be acting), the Lender or any other Person, whether in connection with any Letter of Credit, this Agreement, any other Loan Document, the transactions contemplated herein or any unrelated transactions (including any underlying transaction between any Loan Party and the beneficiary named in any Letter of Credit), (c) the validity, sufficiency or genuineness of any document which the Lender has determined complies on its face with the terms of the applicable Letter of Credit, even if such document should later prove to have been forged, fraudulent, invalid or insufficient in any respect or any statement therein shall have been untrue or inaccurate in any respect, or (d) the surrender or impairment of any security for the performance or observance of any of the terms hereof. Without limiting the foregoing, no action or omission whatsoever by the Lender under or in connection with any Letter of Credit or any related matters shall result in any liability of the Lender to any Borrower, or relieve any Borrower of any of its obligations hereunder to any such Person.

2.4. Certain Conditions. The Lender shall have no obligation to make any Loan, or to permit the continuation of or any conversion into any LIBOR Loan or have any obligation to issue any Letter of Credit, if an Event of Default or Unmatured Event of Default exists.

2.5. Borrower Representative. Each Borrower hereby designates the Borrower Representative as its representative and agent for all purposes under the Loan Documents, including requests for Loans and Letters of Credit, designation of interest rates, delivery or receipt of communications, preparation and delivery of Borrowing Base Certificates and financial reports, receipt and payment of Obligations, requests for waivers, amendments, consents, modifications or other accommodations, actions under the Loan Documents (including in respect of compliance with covenants), and all other dealings with the Lender. Borrower Representative hereby accepts such appointment. The Bank shall be entitled to rely upon, and shall be fully protected in relying upon, any notice or communication (including any notice of borrowing) delivered by Borrower Representative on behalf of the Borrowers or any of them. The Lender may give any notice or communication with a Borrower hereunder to Borrower Representative on behalf of such Borrower. The Lender shall have the right, in its discretion, to deal exclusively with Borrower Representative for any or all purposes under the Loan Documents. Each Borrower agrees that

any notice, election, communication, representation, agreement or undertaking made on its behalf by Borrower Representative shall be binding upon and enforceable against it.

3.1. Note. The Loans of the Lender shall be evidenced by the joint and several Note of the Borrowers, with appropriate insertions, payable to the order of the Lender in a face principal amount equal to Twelve Million and 00/100^th Dollars ($12,000,000).

3.2. Recordkeeping. The Lender, shall record in its records, the date and amount of each Loan made by the Lender, each repayment or conversion thereof and, in the case of each LIBOR Loan, the dates on which each Interest Period for such Loan shall begin and end. The aggregate unpaid principal amount so recorded shall be prima facie evidence of the principal amount of the Loans owing and unpaid. The failure to so record any such amount or any error in so recording any such amount shall not, however, limit or otherwise affect the Obligations of the Borrowers hereunder or under any Note to repay the principal amount of the Loans hereunder, together with all interest accruing thereon.

4.1. Interest Rates. The Borrowers promise to pay interest on the unpaid principal amount of each Loan for the period commencing on the date of such Loan until such Loan is paid in full as follows:

(a) at all times while such Loan is a Base Rate Loan, at a rate per annum equal to the greater of (i) sum of the Base Rate from time to time in effect plus the Base Rate Margin from time to time in effect and (ii) the LIBOR Rate which would have otherwise been applicable to such Loan had Borrowers elected it be a LIBOR Loan with an Interest Period of one month plus the Applicable Margin for LIBOR Loans from time to time in effect; and

(b) at all times while such Loan is a LIBOR Loan, at a rate per annum equal to the sum of the LIBOR Rate applicable to each Interest Period for such Loan plus the LIBOR Margin from time to time in effect;

provided that at any time an Event of Default exists, unless the Lender otherwise consents, the interest rate applicable to each Loan shall be increased by 2% (and, in the case of Obligations not bearing interest, such Obligations shall bear interest at the Base Rate applicable to Revolving Loans plus 2%).

4.2. Interest Payment Dates. Accrued interest on each Base Rate Loan shall be payable in arrears on the last day of each calendar month and at maturity. Accrued interest on each LIBOR Loan shall be payable on the last day of each Interest Period relating to such Loan (and, in the case of a LIBOR Loan with an Interest Period in excess of three months, on the three-month anniversary of the first day of such Interest Period), upon a prepayment of such Loan, and at maturity. After maturity, and at any time an Event of Default exists, accrued interest on all Loans shall be payable on demand.

4.3. Setting and Notice of LIBOR Rates. The applicable LIBOR Rate for each Interest Period shall be determined by the Lender, and notice thereof shall be given by the Lender promptly to the Borrower Representative. Each determination of the applicable LIBOR Rate by the Lender shall be conclusive and binding upon the parties hereto, in the absence of demonstrable error.

4.4. Computation of Interest. Interest shall be computed for the actual number of days elapsed on the basis of a year of 360 days. The applicable interest rate for each Base Rate Loan shall change simultaneously with each change in the Base Rate.

The Borrowers agree to pay to the Lender a non-use fee, for the period beginning ninety (90) days from the Closing Date to the Termination Date, at the Non-Use Fee Rate in effect from time to time the unused amount of the Revolving Authorization. For purposes of calculating usage under this Section, the Revolving Authorization shall be deemed used to the extent of Revolving Outstandings. Such non-use fee shall be payable in arrears on the last day of each calendar quarter and on the Termination Date for any period then ending for which such non-use fee shall not have previously been paid. The non-use fee shall be computed for the actual number of days elapsed on the basis of a year of 360 days. Notwithstanding the foregoing, such non-use fee shall be waived at all times during which the Loan Parties maintain Requisite Minimum Balances with the Lender.

(a) The Borrowers agree to pay to the Lender a letter of credit fee for each Letter of Credit equal to the L/C Fee Rate in effect from time to time of the undrawn amount of such Letter of Credit (computed for the actual number of days elapsed on the basis of a year of 360 days); provided that, unless the Lender otherwise consent, the rate applicable to each Letter of Credit shall be increased by 2% at any time that an Event of Default exists. Such letter of credit fee shall be payable in arrears on the last day of each calendar quarter and on the Termination Date (or such later date on which such Letter of Credit expires or is terminated) for the period from the date of the issuance of each Letter of Credit (or the last day on which the letter of credit fee was paid with respect thereto) to the date such payment is due or, if earlier, the date on which such Letter of Credit expired or was terminated.

(b) In addition, with respect to each Letter of Credit, the Borrowers agree to pay to the Lender such fees and expenses as the Lender customarily requires in connection with the issuance, negotiation, processing and/or administration of letters of credit in similar situations.

5.3. Closing Fee. The Borrowers agree to pay to the Lender a non-refundable closing fee in an amount equal to $25,000 on the date which is ninety (90) days after the Closing Date, provided such fee will be waived if prior to the end of such 90 day period and all times thereafter through the Termination Date, the Borrowers establish and maintain Requisite Minimum Balances.

6.1.1 Voluntary Reduction or Termination of the Revolving Authorization. The Borrowers may from time to time on at least five Business Days’ prior written notice from the Borrower Representative received by the Lender permanently reduce the Revolving Authorization to an amount not less than the Revolving Outstandings. Any such reduction shall be in an amount not less than $500,000 or a higher integral multiple of $100,000. Concurrently with any reduction of the Revolving Authorization to zero, the Borrowers shall pay all interest on the Revolving Loans, all non-use fees and all letter of credit fees and shall Cash Collateralize in full all obligations arising with respect to the Letters of Credit.

Any such partial prepayment shall be in an amount equal to $500,000 or a higher integral multiple of $100,000.

(a) If on any day the Revolving Outstandings exceeds the Borrowing Base, the Borrowers shall immediately prepay Revolving Loans and/or Cash Collateralize the outstanding Letters of Credit, or do a combination of the foregoing, in an amount sufficient to eliminate such excess.

(b) If on any day on which the Revolving Authorization is reduced pursuant to Section 6.1.1 the Revolving Outstandings exceeds the Revolving Authorization, the Borrowers shall immediately prepay Revolving Loans or Cash Collateralize the outstanding Letters of Credit, or do a combination of the foregoing, in an amount sufficient to eliminate such excess.

6.3.1 All Prepayments. Each voluntary partial prepayment shall be in a principal amount of $500,000 or a higher integral multiple of $100,000. Any partial prepayment of a Group of LIBOR Loans shall be subject to the proviso to Section 2.2.3(a). Any prepayment of a LIBOR Loan on a day other than the last day of an Interest Period therefor shall include interest on the principal amount being repaid and shall be subject to Section 8.4. Except as otherwise provided by this Agreement, all principal payments in respect of the Loans shall be applied first, to repay outstanding Base Rate Loans and then to repay outstanding LIBOR Rate Loans in direct order of Interest Period maturities.

6.4.1 Revolving Loans. The Revolving Loans shall be paid in full and the Revolving Authorization shall terminate on the Termination Date.

7.1. Making of Payments. All payments of principal or interest on the Note, and of all fees, shall be made by the Borrowers to the Lender in immediately available funds at the office specified by the Lender not later than noon, Chicago time, on the date due; and funds received after that hour shall be deemed to have been received by the Lender on the following Business Day.

7.2. Application of Certain Payments. So long as no Unmatured Event of Default or Event of Default has occurred and is continuing, (a) payments matching specific scheduled payments then due shall be applied to those scheduled payments and (b) voluntary and mandatory prepayments shall be applied as set forth in Sections 6.2 and 6.3. After the occurrence and during the continuance of an Unmatured Event of Default or Event of Default, all amounts collected or received by the Lender as proceeds from the sale of, or other realization upon, all or any part of the Collateral shall be applied as the Lender shall determine in its discretion or, in the absence of a specific determination by the Lender, as set forth in the Guaranty and Security Agreement.

7.3. Due Date Extension. If any payment of principal or interest with respect to any of the Loans, or of any fees, falls due on a day which is not a Business Day, then such due date shall be extended to the immediately following Business Day (unless, in the case of a LIBOR Loan, such immediately following Business Day is the first Business Day of a calendar month, in which case such due date shall be the immediately preceding Business Day) and, in the case of principal, additional interest shall accrue and be payable for the period of any such extension.

7.4. Setoff. Each Borrower, for itself and each other Loan Party, agrees that the Lender has all rights of set-off and bankers’ lien provided by applicable law, and in addition thereto, each Borrower, for itself and each other Loan Party, agrees that at any time any Event of Default exists, the Lender may apply to the payment of any Obligations of the Borrowers and each other Loan Party hereunder, whether or not then due, any and all balances, credits, deposits, accounts or moneys of such Borrower and each other Loan Party then or thereafter with the Lender.

(a) All payments made by the Borrowers hereunder or under any Loan Documents shall be made without setoff, counterclaim, or other defense. To the extent permitted by applicable law, all payments hereunder or under the Loan Documents (including any payment of principal, interest, or fees) to, or for the benefit, of any person shall be made by the Borrowers free and clear of and without deduction or withholding for, or account of, any Taxes now or hereinafter imposed by any taxing authority.

(b) If the Lender is required by law to make any payments of any Taxes on or in relation to any amounts received or receivable hereunder or under any other Loan Document, or any Tax is assessed against the Lender with respect to amounts received or receivable hereunder or under any other Loan Document, the Borrowers will indemnify the Lender against (i) such Tax (and any reasonable counsel fees and expenses associated with such Tax) and (ii) any taxes imposed as a result of the receipt of the payment under this Section 7.5(b). A certificate prepared in good faith as to the amount of such payment by the Lender, absent manifest error, be final, conclusive, and binding on all parties.

(a) If, after the date hereof, the adoption of, or any change in, any applicable law, rule or regulation, or any change in the interpretation or administration of any applicable law, rule or regulation by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Lender with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: (i) shall impose, modify or deem applicable any reserve (including any reserve imposed by the FRB, but excluding any reserve included in the determination of the LIBOR Rate pursuant to Section 4), special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by the Lender; or (ii) shall impose on the Lender any other condition affecting its LIBOR Loans, its Note or its obligation to make LIBOR Loans; and the result of anything described in clauses (i) and (ii) above is to increase the cost to (or to impose a cost on) the Lender (or any LIBOR Office of the Lender) of making or maintaining any LIBOR Loan, or to reduce the amount of any sum received or receivable by the Lender (or its LIBOR Office) under this Agreement or under its Note with respect thereto, then upon demand by the Lender (which demand shall be accompanied by a statement setting forth the basis for such demand and a calculation of the amount thereof in reasonable detail), the Borrowers shall pay to the Lender such additional amount as will compensate the Lender for such increased cost or such reduction.

(b) If the Lender shall reasonably determine that any change in, or the adoption or phase-in of, any applicable law, rule or regulation regarding capital adequacy, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or the compliance by the Lender or any Person controlling the Lender 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 the Lender’s or such controlling Person’s capital as a consequence of the Lender’s obligations hereunder or under any Letter of Credit to a level below that which the Lender or such controlling Person could have achieved but for such change, adoption, phase-in or compliance (taking into consideration the Lender’s or such controlling Person’s policies with respect to capital adequacy) by an amount deemed by the Lender or such controlling Person to be material, then from time to time, upon demand by the Lender (which demand shall be accompanied by a statement setting

forth the basis for such demand and a calculation of the amount thereof in reasonable detail), the Borrowers shall pay to the Lender such additional amount as will compensate the Lender or such controlling Person for such reduction.

(a) the Lender reasonably determines (which determination shall be binding and conclusive on the Borrowers) that by reason of circumstances affecting the interbank LIBOR market adequate and reasonable means do not exist for ascertaining the applicable LIBOR Rate; or

(b) the LIBOR Rate as determined by the Lender will not adequately and fairly reflect the cost to the Lender of maintaining or funding LIBOR Loans for such Interest Period (taking into account any amount to which the Lender may be entitled under Section 8.1) or that the making or funding of LIBOR Loans has become impracticable as a result of an event occurring after the date of this Agreement which in the opinion of the Lender materially affects such Loans;

then the Lender shall promptly notify the Borrower Representative thereof and, so long as such circumstances shall continue, (i) the Lender shall not be under any obligation to make or convert any Base Rate Loans into LIBOR Loans and (ii) on the last day of the current Interest Period for each LIBOR Loan, such Loan shall, unless then repaid in full, automatically convert to a Base Rate Loan.

8.3. Changes in Law Rendering LIBOR Loans Unlawful. If any change in, or the adoption of any new, law or regulation, or any change in the interpretation of any applicable law or regulation by any governmental or other regulatory body charged with the administration thereof, should make it (or in the good faith judgment of the Lender cause a substantial question as to whether it is) unlawful for the Lender to make, maintain or fund LIBOR Loans, then the Lender shall promptly notify the Borrower Representative thereof and, so long as such circumstances shall continue, (a) the Lender shall have no obligation to make or convert any Base Rate Loan into a LIBOR Loan and (b) on the last day of the current Interest Period for each LIBOR Loan (or, in any event, on such earlier date as may be required by the relevant law, regulation or interpretation), such LIBOR Loan shall, unless then repaid in full, automatically convert to a Base Rate Loan.

8.4. Funding Losses. The Borrowers hereby agree that upon demand by the Lender (which demand shall be accompanied by a statement setting forth the basis for the amount being claimed), the Borrowers will indemnify the Lender against any net loss or expense which the Lender may sustain or incur (including any net loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by the Lender to fund or maintain any LIBOR Loan), as reasonably determined by the Lender, as a result of (a) any payment, prepayment or conversion of any LIBOR Loan on a date other than the last day of an Interest Period for such Loan (including any conversion pursuant to Section 8.3) or (b) any failure of the Borrowers to borrow, convert or continue any Loan on a date specified therefor in a

notice of borrowing, conversion or continuation pursuant to this Agreement. For this purpose, all notices to the Lender pursuant to this Agreement shall be deemed to be irrevocable.

8.5. Right of Lender to Fund through Other Offices. The Lender may, if it so elects, funds any LIBOR Loan by causing a foreign branch or Affiliate of the Lender to make such Loan; provided that in such event for the purposes of this Agreement such Loan shall be deemed to have been made by the Lender and the obligation of the Borrowers to repay such Loan shall nevertheless be to the Lender and shall be deemed held by it, to the extent of such Loan, for the account of such branch or Affiliate.

8.6. Discretion of Lender as to Manner of Funding. Notwithstanding any provision of this Agreement to the contrary, the Lender shall be entitled to fund and maintain its funding of all or any part of its Loans in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if the Lender had actually funded and maintained each LIBOR Loan during each Interest Period for such Loan through the purchase of deposits having a maturity corresponding to such Interest Period and bearing an interest rate equal to the LIBOR Rate for such Interest Period.

The Lender shall promptly notify the Borrower Representative of any event of which it has knowledge which will result in, and will use reasonable commercial efforts available to it (and not, in the Lender’s sole judgment, otherwise disadvantageous to the Lender) to mitigate or avoid, (i) any obligation by the Borrowers to pay any amount pursuant to Sections 7.5 or 8.1 or (ii) the occurrence of any circumstances described in Sections 8.2 or 8.3 (and, if the Lender has given notice of any such event described in clause (i) or (ii) above and thereafter such event ceases to exist, the Lender shall promptly so notify the Borrower Representative). Without limiting the foregoing, the Lender will designate a different funding office if such designation will avoid (or reduce the cost to the Borrowers of) any event described in clause (i) or (ii) above and such designation will not, in the Lender’s sole judgment, be otherwise disadvantageous to the Lender.

8.8. Conclusiveness of Statements; Survival of Provisions. Determinations and statements of the Lender pursuant to Sections 8.1, 8.2, 8.3 or 8.4 shall be conclusive absent demonstrable error. The Lender may use reasonable averaging and attribution methods in determining compensation under Sections 8.1 and 8.4, and the provisions of such Sections shall survive repayment of the Obligations, cancellation of the Note, expiration or termination of the Letters of Credit and termination of this Agreement.

To induce the Lender to enter into this Agreement and to induce the Lender to make Loans and issue Letters of Credit hereunder, each Borrower represents and warrants to the Lender that:

9.1. Organization. Each Loan Party is validly existing and in good standing under the laws of its jurisdiction of organization; and each Loan Party is duly qualified to do business in each jurisdiction where, because of the nature of its activities or properties, such qualification is required, except for such jurisdictions where the failure to so qualify would not have a Material Adverse Effect.

9.2. Authorization; No Conflict. Each Loan Party is duly authorized to execute and deliver each Loan Document to which it is a party, each Borrower is duly authorized to borrow monies hereunder and each Loan Party is duly authorized to perform its Obligations under each Loan Document to which it is a party. The execution, delivery and performance by each Loan Party of each Loan Document to which it is a party, and the borrowings by each Borrower hereunder, do not and will not (a) require any consent or approval of any governmental agency or authority (other than any consent or approval which has been obtained and is in full force and effect), (b) conflict with (i) any provision of law, (ii) the charter, by-laws or other organizational documents of any Loan Party or (iii) any agreement, indenture, instrument or other document, or any judgment, order or decree, which is binding upon any Loan Party or any of their respective properties or (c) require, or result in, the creation or imposition of any Lien on any asset of any Loan Party (other than Liens in favor of the Lender created pursuant to the Collateral Documents).

9.3. Validity and Binding Nature. Each of this Agreement and each other Loan Document to which any Loan Party is a party is the legal, valid and binding obligation of such Person, enforceable against such Person in accordance with its terms, subject to bankruptcy, insolvency and similar laws affecting the enforceability of creditors’ rights generally and to general principles of equity.

9.4. Financial Condition. The audited consolidated financial statements of the Loan Parties as at March 31, 2008 and the unaudited consolidated financial statements of the Loan Parties as at September 30, 2008 copies of each of which have been delivered to the Lender, were prepared in accordance with GAAP (subject, in the case of such unaudited statements, to the absence of footnotes and to normal year-end adjustments) and present fairly in all material respects the consolidated financial condition of the Loan Parties as at such dates and the results of their operations for the periods then ended.

9.5. No Material Adverse Change. Since March 31, 2008 there has been no material adverse change in the financial condition, operations, assets, business or properties of the Loan Parties taken as a whole (it being acknowledged and understood by the Lender that the mere existence of a loss for any one or more reporting periods which does not materially vary from the projections furnished to the Lender prior to the Closing Date, or the use of cash to fund such losses shall not, in and of itself, constitute a material adverse change).

9.6. Litigation and Contingent Liabilities. No litigation (including derivative actions), arbitration proceeding or governmental investigation or proceeding is pending or, to any Borrower’s knowledge, threatened against any Loan Party which might reasonably be expected to have a Material Adverse Effect, except as set forth in Schedule 9.6. Other than any liability

incident to such litigation or proceedings, no Loan Party has any material contingent liabilities not listed on Schedule 9.6 or permitted by Section 11.1.

9.7. Ownership of Properties; Liens. Each Loan Party owns good and, in the case of real property, marketable title to all of its properties and assets, real and personal, tangible and intangible, of any nature whatsoever (including patents, trademarks, trade names, service marks and copyrights), free and clear of all Liens, charges and claims (including infringement claims with respect to patents, trademarks, service marks, copyrights and the like) except as permitted by Section 11.2.

9.8. Equity Ownership; Subsidiaries. All issued and outstanding Capital Securities of each Loan Party are duly authorized and validly issued, fully paid, non-assessable, and free and clear of all Liens other than those in favor of the Lender, and such securities were issued in compliance with all applicable state and federal laws concerning the issuance of securities. Schedule 9.8 sets forth the authorized Capital Securities of each Loan Party as of the Closing Date. All of the issued and outstanding Capital Securities of the Loan Parties are owned as set forth on Schedule 9.8 as of the Closing Date, and as of the Closing Date all of the issued and outstanding Capital Securities of each Wholly-Owned Subsidiary is, directly or indirectly, owned by Technologies. As of the Closing Date, except as set forth on Schedule 9.8, there are no pre-emptive or other outstanding rights, options, warrants, conversion rights or other similar agreements or understandings for the purchase or acquisition of any Capital Securities of any Loan Party.

(a) The Unfunded Liability of all Pension Plans does not in the aggregate exceed twenty percent of the Total Plan Liability for all such Pension Plans. Each Pension Plan complies in all material respects with all applicable requirements of law and regulations. No contribution failure under Section 412 of the Code, Section 302 of ERISA or the terms of any Pension Plan has occurred with respect to any Pension Plan, sufficient to give rise to a Lien under Section 302(f) of ERISA, or otherwise to have a Material Adverse Effect. There are no pending or, to the knowledge of any Borrower, threatened, claims, actions, investigations or lawsuits against any Pension Plan, any fiduciary of any Pension Plan, or any Loan Party or other any member of the Controlled Group with respect to a Pension Plan or a Multiemployer Pension Plan which could reasonably be expected to have a Material Adverse Effect. Neither any Loan Party nor any other member of the Controlled Group has engaged in any prohibited transaction (as defined in Section 4975 of the Code or Section 406 of ERISA) in connection with any Pension Plan or Multiemployer Pension Plan which would subject that Person to any material liability. Within the past five years, neither any Loan Party nor any other member of the Controlled Group has engaged in a transaction which resulted in a Pension Plan with an Unfunded Liability being transferred out of the Controlled Group, which could reasonably be expected to have a Material Adverse Effect. No Termination Event has occurred or is reasonably expected to occur with respect to any Pension Plan, which could reasonably be expected to have a Material Adverse Effect.

(b) All contributions (if any) have been made to any Multiemployer Pension Plan that are required to be made by any Loan Party or any other member of the Controlled Group under the terms of the plan or of any collective bargaining agreement or by applicable law; neither any Loan Party nor any other member of the Controlled Group has withdrawn or partially withdrawn from any Multiemployer Pension Plan, incurred any withdrawal liability with respect to any such plan or received notice of any claim or demand for withdrawal liability or partial withdrawal liability from any such plan, and no condition has occurred which, if continued, could result in a withdrawal or partial withdrawal from any such plan; and neither any Loan Party nor any other member of the Controlled Group has received any notice that any Multiemployer Pension Plan is in reorganization, that increased contributions may be required to avoid a reduction in plan benefits or the imposition of any excise tax, that any such plan is or has been funded at a rate less than that required under Section 412 of the Code, that any such plan is or may be terminated, or that any such plan is or may become insolvent.

9.10. Investment Company Act. No Loan Party is an “investment company” or a company “controlled” by an “investment company” or a “subsidiary” of an “investment company,” within the meaning of the Investment Company Act of 1940.

9.11. Regulation U. No Loan Party is engaged principally, or as one of its important activities, in the business of extending credit for the purpose of purchasing or carrying Margin Stock.

9.12. Taxes. Each Loan Party has timely filed all tax returns and reports required by law to have been filed by it and has paid all taxes and governmental charges due and payable with respect to such return, except any such taxes or charges which are being diligently contested in good faith by appropriate proceedings and for which adequate reserves in accordance with GAAP shall have been set aside on its books. The Loan Parties have made adequate reserves on their books and records in accordance with GAAP for all taxes that have accrued but which are not yet due and payable. No Loan Party has participated in any transaction that relates to a year of the taxpayer (which is still open under the applicable statute of limitations) which is a “reportable transaction” within the meaning of Treasury Regulation Section 1.6011-4(b)(2) (irrespective of the date when the transaction was entered into).

9.13. Solvency, etc. On the Closing Date, and immediately prior to and after giving effect to the issuance of each Letter of Credit and each borrowing hereunder and the use of the proceeds thereof, with respect to each Loan Party, individually, (a) the fair value of its assets is greater than the amount of its liabilities (including disputed, contingent and unliquidated liabilities) as such value is established and liabilities evaluated in accordance with GAAP, (b) the present fair saleable value of its assets is not less than the amount that will be required to pay the probable liability on its debts as they become absolute and matured, (c) it is able to realize upon its assets and pay its debts and other liabilities (including disputed, contingent and unliquidated liabilities) as they mature in the normal course of business, (d) it does not intend to, and does not believe that it will, incur debts or liabilities beyond its ability to pay as such debts and liabilities mature and (e) it is not engaged in business or a transaction, and is not about to engage in business or a transaction, for which its property would constitute unreasonably small capital.

9.14. Environmental Matters. The on-going operations of each Loan Party comply in all respects with all Environmental Laws, except such non-compliance which could not (if enforced in accordance with applicable law) reasonably be expected to result, either individually or in the aggregate, in a Material Adverse Effect. Each Loan Party has obtained, and maintained in good standing, all licenses, permits, authorizations, registrations and other approvals required under any applicable Environmental Law and required for their respective ordinary course operations, and for their reasonably anticipated future operations, and each Loan Party is in compliance with all terms and conditions thereof, except where the failure to do so could not reasonably be expected to result in material liability to any Loan Party and could not reasonably be expected to result, either individually or in the aggregate, in a Material Adverse Effect. No Loan Party or any of its properties or operations is subject to, or reasonably anticipates the issuance of, any written order from or agreement with any Federal, state or local governmental authority, nor subject to any judicial or docketed administrative or other proceeding, respecting any Environmental Law, Environmental Claim or Hazardous Substance. There are no Hazardous Substances or other conditions or circumstances existing with respect to any property, arising from operations prior to the Closing Date, or relating to any waste disposal, of any Loan Party that would reasonably be expected to result, either individually or in the aggregate, in a Material Adverse Effect. No Loan Party has any underground storage tanks that are not properly registered or permitted under applicable Environmental Laws or that at any time have released, leaked, disposed of or otherwise discharged Hazardous Substances.

9.15. Insurance.

Each Loan Party and its properties are insured with financially sound and reputable insurance companies which are not Affiliates of the Loan Parties, in such amounts, with such deductibles and covering such risks as are customarily carried by companies engaged in similar businesses and owning similar properties in localities where such Loan Parties operate.

9.16. Real Property. Set forth on Schedule 9.16 is a complete and accurate list, as of the Closing Date, of the address of all real property owned or leased by any Loan Party, together with, in the case of leased property, the name and mailing address of the lessor of such property.

All information heretofore or contemporaneously herewith furnished in writing by any Loan Party to the Lender for purposes of or in connection with this Agreement and the transactions contemplated hereby is, and all written information hereafter furnished by or on behalf of any Loan Party to the Lender pursuant hereto or in connection herewith will be, true and accurate in every material respect on the date as of which such information is dated or certified, and none of such information is or will be incomplete by omitting to state any material fact necessary to make such information not misleading in light of the circumstances under which made (it being recognized by the Lender that any projections and forecasts provided by the Loan Parties are based on good faith estimates and assumptions believed by the Loan Parties

to be reasonable as of the date of the applicable projections or assumptions and that actual results during the period or periods covered by any such projections and forecasts may differ from projected or forecasted results).

9.18. Intellectual Property. Each Loan Party owns and possesses or has a license or other right to use all patents, patent rights, trademarks, trademark rights, trade names, trade name rights, service marks, service mark rights and copyrights as are necessary for the conduct of the businesses of the Loan Parties, without any infringement upon rights of others which could reasonably be expected to have a Material Adverse Effect.

9.20. Labor Matters. Except as set forth on Schedule 9.20, no Loan Party is subject to any labor or collective bargaining agreement. There are no existing or threatened strikes, lockouts or other labor disputes involving any Loan Party that singly or in the aggregate could reasonably be expected to have a Material Adverse Effect. Hours worked by and payment made to employees of the Loan Parties are not in violation of the Fair Labor Standards Act or any other applicable law, rule or regulation dealing with such matters.

9.21. No Default. No Event of Default or Unmatured Event of Default exists or would result from the incurrence by any Loan Party of any Debt hereunder or under any other Loan Document.

Until the expiration or termination of the Revolving Authorization and thereafter until all Obligations hereunder and under the other Loan Documents are paid in full and all Letters of Credit have been terminated, each Borrower agrees that it will and will cause each other Loan Party to:

(c) Not, and not permit any other member of the Controlled Group to (i) seek a waiver of the minimum funding standards of ERISA, (ii) terminate or withdraw from any Pension Plan or Multiemployer Pension Plan or (iii) take any other action with respect to any Pension Plan that would reasonably be expected to entitle the PBGC to terminate, impose liability in respect of, or cause a trustee to be appointed to administer, any Pension Plan, unless the actions or events described in clauses (i), (ii) and (iii) individually or in the aggregate would not have a Material Adverse Effect.

10.8. Environmental Matters. If any release or threatened release or other disposal of Hazardous Substances shall occur or shall have occurred on any real property or any other assets of any Loan Party, the Borrowers shall, or shall cause the applicable Loan Party to, cause the prompt containment and removal of such Hazardous Substances and the remediation of such real property or other assets as necessary to comply with all applicable Environmental Laws and to preserve the value of such real property or other assets.
