(f)            any application of any sums by whomsoever paid or howsoever realized to any obligation of the Company, regardless of what obligations of the Company remain unpaid;

(g)           any invalidity or unenforceability, relating to or against the Company or any other Guarantor for any reason, of this Agreement or of any other Transaction Document or any provision of applicable law or regulation purporting to prohibit the payment by the Company or any other Guarantor of the principal of or interest on the Note or the sale of Warrant Stock upon the exercise of the Warrant or any other amount payable by them under the Transaction Documents; or

(h)           any other act or omission to act or delay of any kind by the Purchaser, any holder of the Note, any holder of the Warrant or any other Person or any other circumstance whatsoever that might, but for the provisions of this paragraph, constitute a legal or equitable discharge of the obligations of the Guarantors under the Transaction Documents.

8.2           Discharge Only upon Payment in Full; Reinstatement in Certain Circumstances.  Each Guarantor’s obligations under this Section 8 shall remain in full force and effect until the principal of and interest on the Note has been paid and satisfied in full in cash, the Warrant has been “put” or exercised and all other Obligations shall have been paid and satisfied in full in cash.  If at any time any payment of the principal of or interest on the Note or any other amount payable by the Company under any of the Transaction Documents is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Company or of any Guarantor, or otherwise, each Guarantor’s obligations under this Section 8 with respect to such payment shall be reinstated at such time as though such payment had become due but had not been made at such time.

8.3           Waivers.

(a)           General.  Each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest and any notice not provided for herein, as well as any requirement that at any time any action be taken by the Purchaser, any holder of the Note, any holder of the Warrant or any other Person against the Company, another Guarantor or any other Person.

(b)           Subrogation and Contribution.  Each Guarantor hereby agrees not to exercise or enforce any right of exoneration, contribution, reimbursement, recourse or subrogation available to such Guarantor against any Person liable for payment of the Obligations, or as to any security therefor, unless and until the full amount owing on the Obligations has been paid; and the payment by such Guarantor of any amount pursuant to any of the Transaction Documents on account of credit extended to the Company shall not in any way entitle such Guarantor to any right, title or interest (whether by way of subrogation or otherwise) in and to any of the

49

Obligations or any proceeds thereof or any security therefor unless and until the full amount owing on the Obligations has been paid.

8.4           Limit on Recovery.  Notwithstanding any other provision hereof, the right of recovery against each Guarantor under this Section 8 shall not (to the extent required by or as may be necessary or desirable to ensure the enforceability against such Guarantor of its obligations hereunder or thereunder in accordance with the laws of the jurisdiction of its incorporation or where it carries on business) exceed (x) the amount which would render such Guarantor’s obligations under this Section 8 void or voidable under applicable law, including without limitation fraudulent conveyance law minus (y)  $1.00.

8.5           Stay of Acceleration.  If acceleration of the time for payment of any amount payable by the Company under this Agreement or any other Transaction Document is stayed upon the insolvency, bankruptcy or reorganization of the Company, all such amounts otherwise subject to acceleration under the terms of this Agreement or the other Transaction Documents shall nonetheless be payable jointly and severally by the Guarantors hereunder forthwith on demand by the Purchaser.

8.6           Benefit to Guarantors.  All of the Guarantors that are engaged in business are engaged in related businesses and integrated to such an extent that the financial strength and flexibility of each such Guarantor has a direct impact on the success of each other such Guarantor.  Each Guarantor will derive substantial direct and indirect benefit from the extension of credit hereunder.

8.7           Guarantor Covenants.  Each Guarantor shall take such action as the Company is required by this Agreement to cause such Guarantor to take, and shall refrain from taking such action as the Company is required by this Agreement to prohibit such Guarantor from taking.

9.             Miscellaneous.

9.1           Expenses.  The Company shall pay, indemnify, defend and hold the Purchaser harmless from and against liability for the payment of, and reimburse the Purchaser on demand as and when incurred from and against, (a) all reasonable out-of-pocket costs and expenses incurred by it in connection with the due diligence review of the Company, the preparation, negotiation and execution of the Transaction Documents and the consummation of all of the transactions contemplated hereby and thereby (including, without limitation, all reasonable fees and expenses of legal counsel, environmental consultants and accountants), which costs and expenses shall be payable at the Closing (or immediately upon demand by the Purchaser if not paid at the Closing for any reason), all of the foregoing to be capped at Two Hundred Thousand Dollars ($200,000); (b) all reasonable fees and expenses incurred with respect to any amendments or waivers (whether or not the same become effective) under or in respect of each of the Transaction Documents, the Governing Documents of the Company and/or its

50

Subsidiaries and the other agreements and instruments contemplated hereby and thereby (including, without limitation, in connection with any proposed merger, sale or recapitalization of or involving the Company and/or its Subsidiaries); (c) all recording and filing fees and stamp and other Taxes which may be payable in respect of the execution and delivery of this Agreement or the issuance, delivery or acquisition of any of the Securities; (d) the fees and expenses incurred with respect to the interpretation and enforcement of the rights granted under each of the Transaction Documents, the Governing Documents of the Company and the agreements or instruments contemplated hereby and thereby (including, but not limited to, costs of collection); and (e) all reasonable costs and expenses, due diligence expenses, travel expenses and legal fees incurred by the Purchaser, in connection with their continuing relationship with the Company and its Subsidiaries after the date hereof including, without limitation, reimbursement of costs and expenses pursuant to Sections 4.2 and 4.3 hereof.  If the Company fails to pay when due any amounts due the Purchaser or fails to comply with any of its obligations pursuant to this Agreement or any other agreement, document or instrument executed or delivered in connection herewith, the Company shall upon demand by the Purchaser, pay to the Purchaser such further amounts as shall be sufficient to cover the reasonable cost and expense (including, but not limited to, reasonable attorneys’ fees) incurred by or on behalf of the Purchaser in collecting all such amounts due or in otherwise enforcing the Purchaser’s rights and remedies hereunder.  The Company also agrees to pay to the Purchaser all reasonable costs and expenses incurred by them, including reasonable compensation to their attorneys for all services rendered, in connection with the investigation of any Event of Default and enforcement of their rights hereunder. The Company shall also pay those fees and expenses set forth on the Fees and Expenses Schedule.

9.2           Remedies.  Each holder of Securities shall have all rights and remedies set forth, as applicable, in this Agreement, the Securities, the Stockholders’ Agreement and the Governing Documents (to the extent applicable to the Securities or holders thereof) of the Company and all rights and remedies which such holders have been granted at any time under any other Transaction Document currently in force.  No remedy hereunder or thereunder conferred is intended to be exclusive of any other remedy, and each and every such remedy shall be cumulative and shall be in addition to every other remedy given hereunder or thereunder or now or hereafter existing at law or in equity or by statute or otherwise.  Any Person having any rights under any provision of this Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted at law or in equity.

9.3           Amendments and Waivers.  The provisions of this Agreement may not be amended or waived and the Company may not take any action herein prohibited, or omit to perform any act herein required to be performed by it, without the prior written consent of the Company and Majority Holders; provided, however, that any amendment or amendments that lower the interest rate or lengthen the

51

amortization schedule of the Note shall require the unanimous written consent of the holders of the outstanding principal amount of the Note.

9.4           Survival of Agreement; Indemnities.  All covenants, agreements, representations and warranties contained in this Agreement (including the schedules hereto), the Warrant and the Note, or concurrently with or hereafter made in writing by the Company in connection herewith or therewith, shall survive the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby, regardless of any investigation made by the Purchaser or on their behalf.  In addition, notwithstanding the payment or repayment of all amounts pursuant to this Agreement, the Warrant or the Note, the obligations of the Company pursuant to Sections 9.1, 9.15, 9.16, 9.17, 9.18, 9.19 and 9.20 shall survive indefinitely.

9.5           No Setoffs, Etc.  All payments hereunder and under the Note and the Warrant shall be made by the Company without setoff, offset, deduction or counterclaim, free and clear of all Taxes, levies, imports, duties, fees and charges, and without any withholding, restriction or conditions imposed by any Governmental Authority.  If the Company shall be required by any law to deduct, setoff or withhold any amount from or in respect of any payment to the Purchaser hereunder or under the Note or the Warrant, then the amount so payable to the Purchaser shall be increased as may be necessary so that, after making all required deductions, setoffs and withholdings, the Purchaser shall receive an amount equal to the sum it would have received had no such deductions, setoffs or withholding been made.

9.6           Successors and Assigns.  Except as otherwise expressly provided herein, all representations, warranties, covenants and agreements contained in this Agreement by or on behalf of any of the parties hereto shall bind and inure to the benefit of the respective successors and assigns of the parties hereto whether or not so expressed.  In addition, and whether or not any express assignment has been made, the provisions of this Agreement which are for the Purchaser’ benefit as purchasers or holders of the Securities or Warrant Stock are also for the benefit of, and enforceable by, any subsequent holder of such Securities or such Warrant Stock.

9.7           Severability.  Whenever 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 is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement.

9.8           Counterparts.  This Agreement may be executed in counterparts, either one of which need not contain the signatures of more than one party, but both such counterparts taken together shall constitute one and the same Agreement.

52

9.9           Descriptive Headings.  The descriptive headings of this Agreement are inserted for convenience only and do not constitute a substantive part of this Agreement.

9.10         Governing Law.  The law of the State of Illinois shall govern all issues and questions concerning the relative rights and obligations of the parties and all issues and questions concerning the construction, validity, enforcement and interpretation of this Agreement and the exhibits and schedules hereto shall be construed in accordance with the laws of the State of Illinois, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Illinois or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Illinois.  In furtherance of the foregoing, the internal law of the State of Illinois shall control the interpretation and construction of this Agreement (and all schedules and exhibits hereto), even though under that jurisdiction’s choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply.

9.11         Notices.  All notices, demands or other communications to be given or delivered under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given when delivered personally to the recipient, sent to the recipient by reputable overnight courier service (charges prepaid) or mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid.  Such notices, demands and other communications shall be sent to the parties hereto at their respective addresses indicated below:

9.12         Consideration for Securities; Treatment of Fees.  The Purchaser and the Company acknowledge and agree that the fair market value of the Warrant is $210,000.  The Purchaser and the Company shall file their respective federal, state and local Tax returns in a manner which is consistent with such fair market value figures and shall not take any action or position (whether in preparation of Tax returns, financial statements or otherwise) which is inconsistent with any of the above.

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

9.14         Complete Agreement.  This Agreement, the Senior Subordination Agreement and the applicable Related Transaction Documents embody the complete agreement and understanding among the parties and supersede any prior agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way.

9.15         Indemnification.

(a)           In consideration of the Purchaser’s execution and delivery of this Agreement and acquiring the Securities hereunder and in addition to all of the Company’s other obligations under this Agreement and in addition to all other rights and remedies available at law or in equity, the Company shall defend, protect and indemnify the Purchaser and each other holder the Securities and all of their respective officers, directors, stockholders, partners, members, Affiliates, direct or indirect owners, employees, agents, representatives, successors and assigns (including, without

54

limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnified Parties”), and save and hold each of them harmless against, and pay on behalf of or reimburse such party on demand as and when incurred from and against any and all actions, causes of action, suits, claims, losses (including diminutions in value and consequential damages), out-of-pocket costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnified Party is a party to the action for which indemnification hereunder is sought), including, without limitation, reasonable attorneys’ fees and disbursements, interest and penalties and all amounts paid in investigation, defense or settlement of any of the foregoing and claims relating to any of the foregoing (the “Indemnified Liabilities”), incurred by the Indemnified Parties or any of them as a result of, or arising out of, or relating to (a) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the Securities; or (b) the execution, delivery, performance or enforcement of this Agreement and any other instrument, document or agreement executed pursuant hereto by any of the Indemnified Parties, except to the extent any such Indemnified Liabilities are caused by the particular Indemnified Party’s gross negligence or willful misconduct.  To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law.

(b)           Without limiting the generality of the indemnity set out in Section 9.15(a) above, the Company shall defend, protect, indemnify and hold harmless the Purchaser and all other Indemnified Parties from and against any and all actions, causes of action, suits, losses, liabilities, damages, injuries, penalties, fees, costs, expenses and claims of any and every kind whatsoever paid, incurred or suffered by, or asserted against, the Purchaser or any other Indemnified Party for, with respect to, or as a direct or indirect result of, the past, present or future environmental condition of any property owned, operated or used by the Company or any of its Subsidiaries, their predecessors or successors or of any offsite treatment, storage or disposal location associated therewith, including, without limitation, the presence on or under, or the Release, or threatened Release into, onto or from, any such property or location of any toxic, chemical or Hazardous Materials (including, without limitation, any losses, liabilities, damages, injuries, penalties, fees, costs, expenses or claims asserted or arising under CERCLA, any so-called “Superfund” or “Superlien” law, or any other applicable federal, state, local or foreign statute, law, ordinance, code, rule, regulation, order or decree regulating, relating to or imposing liability or standards on conduct concerning, any toxic, chemical or Hazardous Materials).

55

(c)           In the event that any Indemnified Party is made a defendant in or party to any action or proceeding, judicial or administrative, instituted by any third party for any Indemnified Liabilities (any such third party action or proceeding being referred to as a “Third Party Claim”), the Indemnified Party shall give the Company written notice thereof as soon as practicable after becoming aware of such Third Party Claim.  The failure to give such notice shall not affect any Indemnified Party’s ability to seek reimbursement for Indemnified Liabilities, unless such failure has materially and adversely affected the Company’s ability to defend successfully a Third Party Claim.  The Company shall be entitled to contest and defend such Third Party Claim; provided, that it (i) has a reasonable basis for concluding that such defense may be successful and (ii) diligently contests and defends such Third Party Claim.  Notice of the intention so to contest and defend shall be given by the Company to the Indemnified Party within twenty (20) Business Days after the Indemnified Party’s notice of such Third Party Claim (but, in all events, at least five (5) business days prior to the date that an answer to such Third Party Claim is due to be filed).  Such contest and defense shall be conducted by reputable attorneys employed by the Company.  The Indemnified Party shall be entitled at any time, at its own cost and expense (which expense shall not constitute an Indemnified Liability unless the Indemnified Party reasonably determines that the Company is not adequately representing or, because of a conflict of interest, may not adequately represent, any interests of such Indemnified Party), to participate in such contest and defense and to be represented by attorneys of its or their own choosing.  If the Indemnified Party elects to participate in such defense, the Indemnified Party shall cooperate with the Company in the conduct of such defense.  In no event shall the Company be responsible for the expense of more than one counsel for the Indemnified Parties.  Neither the Indemnified Party nor the Company may concede, settle or compromise any Third Party Claim without the consent of the other party, which consent shall not be unreasonably withheld or delayed.  Notwithstanding the foregoing, in the event the Company fails or is not entitled to contest and defend a claim, the Indemnified Party shall be entitled to contest, defend and settle such Third Party Claim at the expense of the Company.

(d)           In the event any Indemnified Party should have a direct claim against the Company that does not involve a Third Party Claim (a “Direct Claim”), the Indemnified Party shall deliver a notice of such Direct Claim with reasonable promptness to the Company.  If the Company notifies the Indemnified Party that it does not dispute the Direct Claim described in such notice or fails to notify the Indemnified Party within forty-five (45) days after delivery of such notice by the Indemnified Party whether the Company disputes the Direct Claim described in such notice, the Indemnified Liabilities in the amount specified in the Indemnified Party’s notice shall be conclusively deemed a liability of the Company, and the Company shall pay the amount of such Indemnified Liabilities to the

56

Indemnified Party on demand in accordance with the terms hereof.  If the Company gives notice to the Indemnified Party that it disputes the Direct Claim, the Indemnified Party may pursue whatever legal remedies may be available to enforce its rights under this Agreement.

9.16         Payment Set Aside.  To the extent that the Company makes a payment or payments to the Purchaser hereunder or under the Note or the Warrant, or the Purchaser enforce their rights or exercise their right of setoff hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or setoff or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

9.17         Jurisdiction and Venue.  Each of the parties (a) submits to the jurisdiction of any state or federal court sitting in Chicago, Illinois in any legal suit, action or proceeding arising out of or relating to this Agreement, the Note, the Warrant or any other Transaction Document, (b) agrees that all claims in respect of the action or proceeding may be heard or determined in any such court and (c) agrees not to bring any action or proceeding arising out of or relating to this Agreement, the Note, the Warrant or any other Transaction Document in any other court.  Each of the parties waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of any other party with respect thereto.  Any party may make service on any other party by sending or delivering a copy of the process to the party to be served at the address and in the manner provided for the giving of notices in Section 8.11.  Each party agrees that a final judgment in any action or proceeding so brought shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by law.  Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of the Purchaser to bring proceedings against the Company in the courts of any other jurisdiction.  To the extent provided by law, should the Company, after being so served, fail to appear or answer to any summons, complaint, process or papers so served within the number of days prescribed by law after the mailing thereof, the Company shall be deemed in default and an order and/or judgment may be entered by the court against the Company, as demanded or prayed for in such summons, complaint, process or papers.  The exclusive choice of forum for Company set forth in this Section 9.17 shall not be deemed to preclude the enforcement by the Purchaser or the holders of the Note or the Warrant of any judgment obtained in any other forum or the taking by the Purchaser or any holders of the Note or the Warrant of any action to enforce the same in any other appropriate jurisdiction, and Company hereby waives the right to collaterally attack any such judgment or action.

57

9.18         WAIVER OF RIGHT TO JURY TRIAL.  THE COMPANY, THE PURCHASER, THE HOLDERS OF THE NOTE AND THE HOLDERS OF THE WARRANT HEREBY WAIVE, TO THE EXTENT PERMITTED BY APPLICABLE LAW, TRIAL BY JURY IN ANY LITIGATION IN ANY COURT WITH RESPECT TO, IN CONNECTION WITH, OR ARISING OUT OF THIS AGREEMENT, THE NOTE OR THE WARRANT OR THE VALIDITY, PROTECTION, INTERPRETATION, COLLECTION OR ENFORCEMENT RESPECTIVELY, THEREOF.  THE COMPANY AGREES THAT THIS SECTION 9.18 IS A SPECIFIC AND MATERIAL ASPECT OF THIS AGREEMENT AND ACKNOWLEDGE THAT THE PURCHASER WOULD NOT PURCHASE THE SECURITIES HEREUNDER IF THIS SECTION 9.18 WERE NOT PART OF THIS AGREEMENT.

9.19         Certain Waivers.  The Company hereby waives diligence, presentment, protest and demand and notice of protest and demand, dishonor and nonpayment of the Note, and expressly agrees that the Note, or any payment thereunder, may be extended from time to time and that the holders thereof may accept security for the Note or release security for the Note, all without in any way affecting the liability of the Company thereunder.

9.20         Transfer Restrictions.  The Securities acquired pursuant hereto are subject to the applicable transfer restrictions contained herein, in the Note, the Warrant and the Stockholders’ Agreement, as the case may be.
