Subsidiaries Guaranty

SUBSIDIARIES GUARANTY, dated as of November 13, 2003 (as amended, amended and restated, modified and/or supplemented from time to time, this “Guaranty”), made by each of the undersigned (each, a “Guarantor” and, together with any other entity which becomes a party hereto pursuant to Section 24, collectively, the “Guarantors”). Except as otherwise defined herein, terms used herein and defined in the Credit Agreement (as defined below) shall be used herein as therein defined.

WHEREAS, Quality Distribution, Inc. (“Holdings”), Quality Distribution, LLC (the “Borrower”), the lenders from time to time party thereto (the “Lenders”), Deutsche Bank Securities Inc, and Bear Stearns Corporate Lending Inc., as Co-Syndication Agents (the “Co-Syndication Agents”), JPMorgan Chase Bank, as Documentation Agent (the “Documentation Agent”), and Credit Suisse First Boston, acting through its Cayman Islands Branch, as Administrative Agent (the “Administrative Agent”), have entered into a Credit Agreement, dated as of November 13, 2003 (as amended, amended and restated, modified and/or supplemented from time to time, the “Credit Agreement”), providing for the making of Loans to the Borrower and the issuance of, and participation in, Letters of Credit for the account of the Borrower, all as contemplated therein (with the Lenders, the Documentation Agent, the Co-Syndication Agents, the Administrative Agent and the Collateral Agent being herein called the “Lender Creditors”);

WHEREAS, the Borrower may at any time and from time to time enter into one or more Interest Rate Protection Agreements or Other Hedging Agreements with one or more Lenders or any affiliate thereof (each such Lender or affiliate, even if the respective Lender subsequently ceases to be a Lender under the Credit Agreement for any reason, together with such Lender’s or affiliate’s successors and assigns, if any, collectively, the “Other Creditors” and, together with the Lender Creditors, the “Creditors”);

WHEREAS, it is a condition precedent to the making of Loans and the issuance of, and participation in, Letters of Credit for the account of the Borrower under the Credit Agreement and to the Other Creditors entering into Interest Rate Protection Agreements and/or Other Hedging Agreements with the Borrower that each Guarantor shall have executed and delivered this Guaranty; and

WHEREAS, each Guarantor will obtain benefits from the incurrence of Loans by the Borrower and the issuance of, and participation in, Letters of Credit for the account of the Borrower under the Credit Agreement and the entering into of Interest Rate Protection Agreements and/or Other Hedging Agreements with an Other Creditor and, accordingly, desires to execute this Guaranty in order to satisfy the conditions described in the preceding paragraph and to induce the Lenders to make and maintain Loans to the Borrower and issue Letters of Credit for the account of the Borrower and the Other Creditors to enter into and/or maintain Interest Rate Protection Agreements and/or Other Hedging Agreements with the Borrower;

NOW, THEREFORE, in consideration of the foregoing and other benefits accruing to each Guarantor, the receipt and sufficiency of which are hereby acknowledged, each Guarantor hereby makes the following representations and warranties to the Creditors and hereby covenants and agrees with each Creditor as follows:

1. Each Guarantor, jointly and severally, irrevocably, absolutely and unconditionally guarantees: (i) to the Lender Creditors the full and prompt payment when due (whether at the stated maturity, by acceleration or otherwise) of (x) the principal of, premium, if any, and interest on all Notes issued, and all Loans made, under the Credit Agreement and all reimbursement obligations and Unpaid Drawings with respect to Letters of Credit and (y) all other obligations (including obligations which, but for any automatic stay under Section 362(a) of the Bankruptcy Code, would become due) and liabilities owing by the Borrower to the Lender Creditors (including, without limitation, indemnities, Fees and interest thereon (including any interest accruing after the commencement of any bankruptcy, insolvency, receivership or similar proceeding at the rate provided for in the Credit Agreement, whether or not such interest is an allowed claim in any such proceeding)) now existing or hereafter incurred under, arising out of or in connection with the Credit Agreement or any other Credit Document and the due performance and compliance by the Borrower with the terms, conditions, covenants and agreements contained in the Credit Documents (all such principal, premium, interest, liabilities, indebtedness and obligations under this clause (i), except to the extent consisting of obligations or liabilities with respect to Interest Rate Protection Agreements or Other Hedging Agreements, being herein collectively called the “Credit Document Obligations”); and (ii) to each Other Creditor the full and prompt payment when due (whether at the stated maturity, by acceleration or otherwise) of all obligations (including obligations which, but for any automatic stay under Section 362(a) of the Bankruptcy Code, would become due) and liabilities owing by the Borrower to the Other Creditors (including, without limitation, indemnities, fees and interest thereon (including any interest accruing after the commencement of any bankruptcy, insolvency, receivership or similar proceeding at the rate provided for in the respective Interest Rate Protection Agreements or Other Hedging Agreements, whether or not such interest is an allowed claim in any such proceeding)) under each Interest Rate Protection Agreement and each Other Hedging Agreement, whether now in existence or hereafter arising, and the due performance and compliance by the Borrower with all terms, conditions, covenants and agreements contained therein (all such obligations and liabilities under this clause (ii) being herein collectively called the “Other Obligations”, and together with the Credit Document Obligations are herein collectively called the “Guaranteed Obligations”). Each Guarantor understands, agrees and confirms that the Creditors may enforce this Guaranty up to the full amount of the Guaranteed Obligations against each Guarantor without proceeding against any other Guarantor, the Borrower, against any security for the Guaranteed Obligations, or against any other guarantor under any other guaranty covering all or a portion of the Guaranteed Obligations. This Guaranty shall constitute a guaranty of payment and not of collection. All payments by each Guarantor under this Guaranty shall be made on the same basis as payments by the Borrower under Sections 4.03 and 4.04 of the Credit Agreement.

2. Additionally, each Guarantor, jointly and severally, unconditionally and irrevocably, guarantees the payment of any and all Guaranteed Obligations to the Creditors

whether or not due or payable by the Borrower upon the occurrence in respect of the Borrower of any of the events specified in Section 10.05 of the Credit Agreement, and unconditionally and irrevocably, jointly and severally, promises to pay such Guaranteed Obligations to the Creditors, or order, on demand, in U.S. Dollars.

3. The liability of each Guarantor hereunder is primary, absolute, joint and several, and unconditional and is exclusive and independent of any security for or other guaranty of the Guaranteed Obligations whether executed by such Guarantor, any other Guarantor, any other guarantor of the Borrower or by any other party, and the liability of each Guarantor hereunder shall not be affected or impaired by (i) any direction as to application of payment by the Borrower or by any other party, (ii) any other continuing or other guaranty, undertaking or maximum liability of a guarantor or of any other party as to the Guaranteed Obligations, (iii) any payment on or in reduction of any such other guaranty or undertaking, (iv) any dissolution, termination or increase, decrease or change in personnel by the Borrower, (v) any payment made to any Creditor on the Guaranteed Obligations which any Creditor repays the Borrower pursuant to court order in any bankruptcy, reorganization, arrangement, moratorium or other debtor relief proceeding, and each Guarantor waives any right to the deferral or modification of its obligations hereunder by reason of any such proceeding, (vi) any action or inaction by the Creditors as contemplated in Section 6 hereof or (vii) any invalidity, irregularity or unenforceability of all or any part of the Guaranteed Obligations or of any security therefor.

4. The obligations of each Guarantor hereunder are independent of the obligations of any other Guarantor, any other guarantor of the Borrower or the Borrower, and a separate action or actions may be brought and prosecuted against each Guarantor whether or not action is brought against any other Guarantor, any other guarantor of the Borrower or the Borrower and whether or not any other Guarantor, any other guarantor of the Borrower or the Borrower be joined in any such action or actions. Each Guarantor waives, to the fullest extent permitted by law, the benefit of any statute of limitations affecting its liability hereunder or the enforcement thereof. Any payment by the Borrower or other circumstance which operates to toll any statute of limitations as to the Borrower shall operate to toll the statute of limitations as to each Guarantor.

5. Each Guarantor hereby waives notice of acceptance of this Guaranty and notice of any liability to which it may apply, and waives promptness, diligence, presentment, demand of payment, protest, notice of dishonor or nonpayment of any such liabilities, suit or taking of other action by the Administrative Agent or any other Creditor against, and any other notice to, any party liable thereon (including such Guarantor, any other guarantor of the Borrower or the Borrower).

6. Any Creditor may at any time and from time to time without the consent of, or notice to, any Guarantor, without incurring responsibility to such Guarantor, without impairing or releasing the obligations of such Guarantor hereunder, upon or without any terms or conditions and in whole or in part:

(i) change the manner, place or terms of payment of, and/or change, increase or extend the time of payment of, renew or alter, any of the Guaranteed Obligations (including any increase or decrease in the rate of interest thereon or the principal amount thereof), any security therefor, or any liability incurred directly or indirectly in respect thereof, and the guaranty herein made shall apply to the Guaranteed Obligations as so changed, extended, renewed or altered;

(ii) take and hold security for the payment of the Guaranteed Obligations and/or sell, exchange, release, surrender, impair, realize upon or otherwise deal with in any manner and in any order any property by whomsoever at any time pledged or mortgaged to secure, or howsoever securing, the Guaranteed Obligations or any liabilities (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and/or any offset thereagainst;

(iii) exercise or refrain from exercising any rights against the Borrower, any Guarantor, any other guarantor of the Borrower or others or otherwise act or refrain from acting;

(iv) settle or compromise any of the Guaranteed Obligations, any security therefor or any liability (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any liability (whether due or not) of the Borrower to creditors of the Borrower;

(v) apply any sums by whomsoever paid or howsoever realized to any liability or liabilities of the Borrower to the Creditors regardless of what liabilities of the Borrower remain unpaid;

(vi) release or substitute any one or more endorsers, guarantors, Guarantors, the Borrower or other obligors;

(vii) consent to or waive any breach of, or any act, omission or default under, any of the Interest Rate Protection Agreements or Other Hedging Agreements, the Credit Documents or any of the instruments or agreements referred to therein, or otherwise amend, modify or supplement any of the Interest Rate Protection Agreements or Other Hedging Agreements, the Credit Documents or any of such other instruments or agreements;

(viii) act or fail to act in any manner referred to in this Guaranty which may deprive such Guarantor of its right to subrogation against the Borrower to recover full indemnity for any payments made pursuant to this Guaranty; and/or

(ix) take any other action or omit to take any other action which would, under otherwise applicable principles of common law, give rise to a legal or equitable discharge of such Guarantor from its liabilities under this Guaranty (including, without limitation,

any action or omission whatsoever that might otherwise vary the risk of the Guarantor or constitute a legal or equitable defense to or discharge of the liabilities of a guarantor or surety or that might otherwise limit recourse against the Guarantor).

7. No invalidity, irregularity or unenforceability of all or any part of the Guaranteed Obligations or of any security therefor shall affect, impair or be a defense to this Guaranty, and this Guaranty shall be primary, absolute and unconditional notwithstanding the occurrence of any event or the existence of any other circumstances which might constitute a legal or equitable discharge of a surety or guarantor except payment in full of the Guaranteed Obligations.

8. This Guaranty is a continuing one and all liabilities to which it applies or may apply under the terms hereof shall be conclusively presumed to have been created in reliance hereon. No failure or delay on the part of any Creditor in exercising any right, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein expressly specified are cumulative and not exclusive of any rights or remedies which any Creditor would otherwise have. No notice to or demand on any Guarantor in any case shall entitle such Guarantor to any other further notice or demand in similar or other circumstances or constitute a waiver of the rights of any Creditor to any other or further action in any circumstances without notice or demand. It is not necessary for any Creditor to inquire into the capacity or powers of Holdings or any of its Subsidiaries or the officers, directors, partners or agents acting or purporting to act on its behalf, and any indebtedness made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder.

9. Any indebtedness of the Borrower now or hereafter held by any Guarantor is hereby subordinated to the indebtedness of the Borrower to the Creditors; and such indebtedness of the Borrower to any Guarantor, if the Administrative Agent, after the occurrence and during the continuance of an Event of Default, so requests, shall be collected, enforced and received by such Guarantor as trustee for the Creditors and be paid over to the Creditors on account of the indebtedness of the Borrower to the Creditors, but without affecting or impairing in any manner the liability of such Guarantor under the other provisions of this Guaranty. Prior to the transfer by any Guarantor of any note or negotiable instrument evidencing any indebtedness of the Borrower to such Guarantor (other than transfers between Guarantors and between the Borrower and any Guarantor), such Guarantor shall mark such note or negotiable instrument with a legend that the same is subject to this subordination. Without limiting the generality of the foregoing, each Guarantor hereby agrees with the Creditors that it will not exercise any right of subrogation which it may at any time otherwise have as a result of this Guaranty (whether contractual, under Section 509 of the Bankruptcy Code or otherwise) until all Guaranteed Obligations have been irrevocably paid in full in cash.

10. (a) Each Guarantor waives any right (except as shall be required by applicable statute and cannot be waived) to require the Creditors to: (i) proceed against the Borrower, any other Guarantor, any other guarantor of the Borrower or any other party; (ii) proceed

against or exhaust any security held from the Borrower, any other Guarantor, any other guarantor of the Borrower or any other party; or (iii) pursue any other remedy in the Creditors’ power whatsoever. Each Guarantor waives any defense based on or arising out of any defense of the Borrower, any other Guarantor, any other guarantor of the Borrower or any other party other than payment in full in cash of the Guaranteed Obligations, including, without limitation, any defense based on or arising out of the disability of the Borrower, any other Guarantor, any other guarantor of the Borrower or any other party, or the unenforceability of the Guaranteed Obligations or any part thereof from any cause, or the cessation from any cause of the liability of the Borrower other than payment in full in cash of the Guaranteed Obligations. The Creditors may, at their election, foreclose on any security held by the Administrative Agent, the Collateral Agent or the other Creditors by one or more judicial or nonjudicial sales, whether or not every aspect of any such sale is commercially reasonable (to the extent such sale is permitted by applicable law), or exercise any other right or remedy the Creditors may have against the Borrower or any other party, or any security, without affecting or impairing in any way the liability of any Guarantor hereunder except to the extent the Guaranteed Obligations have been paid in full in cash. Each Guarantor waives any defense arising out of any such election by the Creditors, even though such election operates to impair or extinguish any right of reimbursement or subrogation or other right or remedy of such Guarantor against the Borrower, any other Guarantor or any other party or any security.

(b) Each Guarantor waives all presentments, demands for performance, protests and notices, including, without limitation, notices of nonperformance, notices of protest, notices of dishonor, notices of acceptance of this Guaranty, and notices of the existence, creation or incurring of new or additional indebtedness. Each Guarantor assumes all responsibility for being and keeping itself informed of the Borrower’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks which such Guarantor assumes and incurs hereunder, and agrees that the Creditors shall have no duty to advise any Guarantor of information known to them regarding such circumstances or risks.

(c) Until such time as the Guaranteed Obligations have been paid in full in cash, each Guarantor hereby waives all contractual, statutory or common law rights of reimbursement, contribution or indemnity from the Borrower or any other Guarantor which it may at any time otherwise have as a result of this Guaranty.

11. In order to induce the Lenders to make Loans and issue Letters of Credit pursuant to the Credit Agreement, and in order to induce the Other Creditors to execute, deliver and perform the Interest Rate Protection Agreements or Other Hedging Agreements, each Guarantor represents, warrants and covenants that:

(a) such Guarantor (i) is a duly organized and validly existing Company and is in good standing under the laws of the jurisdiction of its organization, and has the Company power and authority to own its property and assets and to transact the business in which it is engaged and presently proposes to engage and (ii) is duly qualified and is authorized to do business and is in good standing in all jurisdictions where it is required to be so qualified except where the failure to be so qualified could reasonably be expected to have a Material Adverse Effect.

(b) such Guarantor has the Company power and authority to execute, deliver and carry out the terms and provisions of this Guaranty and each other Document (for purposes of this Guaranty, such term to mean and include each Document (as defined in the Credit Agreement) and each Interest Rate Protection Agreement and each Other Hedging Agreement with an Other Creditor) to which it is a party and has taken all necessary Company action to authorize the execution, delivery and performance by it of each such Document. Such Guarantor has duly executed and delivered this Guaranty and each other Document to which it is a party, and each such Document constitutes the legal, valid and binding obligation of such Guarantor enforceable in accordance with its terms, except to the extent that the enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws generally affecting creditors’ rights and by equitable principles (regardless of whether enforcement is sought in equity or law).

(c) neither the execution, delivery or performance by such Guarantor of this Guaranty or any other Document to which it is a party, nor compliance by it with the terms and provisions hereof and thereof: (i) will contravene any applicable material provision of any law, statute, rule or regulation, or any order, writ, injunction or decree of any court or governmental instrumentality, (ii) will conflict or be inconsistent with or result in any breach of, any of the terms, covenants, conditions or provisions of, or constitute a default under, or (other than pursuant to the Security Documents) result in the creation or imposition of (or the obligation to create or impose) any Lien upon any of the property or assets of such Guarantor or any of its Subsidiaries pursuant to the terms of any indenture, mortgage, deed of trust, credit agreement, loan agreement or any other material agreement or other instrument to which such Guarantor or any of its Subsidiaries is a party or by which it or any of its property or assets is bound or to which it may be subject or (iii) will violate any provision of the certificate of incorporation or by-laws (or equivalent organizational documents) of such Guarantor or any of its Subsidiaries.

(d) no order, consent, approval, license, authorization or validation of, or filing, recording or registration with, or exemption by, any foreign or domestic governmental or public body or authority, or any subdivision thereof, is required to authorize, or is required in connection with, (i) the execution, delivery and performance of this Guaranty or any other Document to which such Guarantor is a party, or (ii) the legality, validity, binding effect or enforceability of this Guaranty or any other Document to which such Guarantor is a party.

12. Each Guarantor covenants and agrees that on and after the date hereof and until the termination of the Total Commitment and all Interest Rate Protection Agreements and Other Hedging Agreements with an Other Creditor, no Note or Letter of Credit remains outstanding and all other Guaranteed Obligations have been paid in full (other than those arising from indemnities for which no request has been made), such Guarantor shall take, or will refrain

from taking, as the case may be, all actions that are necessary to be taken or not taken so that no violation of any provision, covenant or agreement contained in Section 8 or 9 of the Credit Agreement, and so that no Event of Default is caused by the actions of such Guarantor or any of its Subsidiaries.

13. The Guarantors hereby jointly and severally agree to pay all reasonable out-of-pocket costs and expenses of each Creditor in connection with the enforcement of this Guaranty and the protection of such Creditor’s rights hereunder, and in connection with any amendment, waiver or consent relating hereto (including, without limitation, the reasonable fees and disbursements of counsel employed by the Administrative Agent or any of the Creditors).

14. This Guaranty shall be binding upon each Guarantor and its successors and assigns and shall inure to the benefit of the Creditors and their successors and assigns.

15. Neither this Guaranty nor any provision hereof may be changed, waived, discharged or terminated in any manner whatsoever unless in writing duly signed by the Administrative Agent (with the consent of (x) the Required Lenders or, to the extent required by Section 13.12 of the Credit Agreement, all of the Lenders, at all times prior to the time at which all Credit Document Obligations have been paid in full, or (y) the holders of at least a majority of the outstanding Other Obligations at all times after the time at which all Credit Document Obligations have been paid in full) and each Guarantor directly affected thereby (it being understood that the addition or release of any Guarantor hereunder shall not constitute a change, waiver, discharge or termination affecting any Guarantor other than the Guarantor so added or released); provided, that any change, waiver, modification or variance affecting the rights and benefits of a single Class (as defined below) of Creditors (and not all Creditors in a like or similar manner) shall also require the written consent of the Requisite Creditors (as defined below) of such Class. For the purpose of this Guaranty, the term “Class” shall mean each class of Creditors, i.e., whether (i) the Lender Creditors as holders of the Credit Document Obligations or (ii) the Other Creditors as holders of the Other Obligations. For the purpose of this Guaranty, the term “Requisite Creditors” of any Class shall mean each of (i) with respect to the Credit Document Obligations, the Required Lenders and (ii) with respect to the Other Obligations, the holders of at least a majority of all Other Obligations outstanding from time to time under the Interest Rate Protection Agreements and/or Other Hedging Agreements.

16. Each Guarantor acknowledges that an executed (or conformed) copy of each of the Credit Documents and the Interest Rate Protection Agreements and Other Hedging Agreements with an Other Creditor has been made available to its principal executive officers and such officers are familiar with the contents thereof.

17. In addition to any rights now or hereafter granted under applicable law (including, without limitation, Section 151 of the New York Debtor and Creditor Law) and not by way of limitation of any such rights, upon the occurrence and during the continuance of an Event of Default (such term to mean and include any “Event of Default” as defined in the Credit Agreement or any payment default under any Interest Rate Protection Agreement or Other Hedging Agreement and shall in any event, include, without limitation, any payment default on

any of the Guaranteed Obligations continuing after any applicable grace period), each Creditor is hereby authorized at any time or from time to time, without notice to any Guarantor or to any other Person, any such notice being expressly waived, to set off and to appropriate and apply any and all deposits (general or special) and any other indebtedness at any time held or owing by such Creditor to or for the credit or the account of such Guarantor, against and on account of the obligations and liabilities of such Guarantor to such Creditor under this Guaranty, irrespective of whether or not such Creditor shall have made any demand hereunder and although said obligations, liabilities, deposits or claims, or any of them, shall be contingent or unmatured. Each Creditor (by its acceptance of the benefits hereof) acknowledges and agrees that the provisions of this Section 17 are subject to the sharing provisions set forth in Section 13.06(b) of the Credit Agreement.

18. All notices, requests, demands or other communications pursuant hereto shall be deemed to have been duly given or made when delivered to the Person to which such notice, request, demand or other communication is required or permitted to be given or made under this Guaranty, addressed to such party at (i) in the case of any Lender Creditor, as provided in the Credit Agreement, (ii) in the case of any Guarantor, c/o:

and (iii) in the case of any Other Creditor, at such address as such Other Creditor shall have specified in writing to the Guarantor; or in any case at such other address as any of the foregoing Persons may hereafter notify the others in writing.

19. If claim is ever made upon any Creditor for repayment or recovery of any amount or amounts received in payment or on account of any of the Guaranteed Obligations and any of the aforesaid payees repays all or part of said amount by reason of (i) any judgment, decree or order of any court or administrative body having jurisdiction over such Creditor or any of its property or (ii) any settlement or compromise of any such claim effected by such Creditor with any such claimant (including the Borrower), then and in such event each Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding upon such Guarantor, notwithstanding any revocation hereof or the cancellation of any Note or any Interest Rate Protection Agreement or Other Hedging Agreement or other instrument evidencing any liability of the Borrower, and such Guarantor shall be and remain liable to such Creditor hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by any such Creditor.

20. (A) THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE CREDITORS AND OF THE UNDERSIGNED HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

(B) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS GUARANTY OR ANY OTHER CREDIT DOCUMENT TO WHICH ANY GUARANTOR IS A PARTY MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS GUARANTY, EACH GUARANTOR HEREBY IRREVOCABLY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. EACH GUARANTOR HEREBY FURTHER IRREVOCABLY WAIVES ANY CLAIM THAT ANY SUCH COURTS LACK JURISDICTION OVER SUCH GUARANTOR, AND AGREES NOT TO PLEAD OR CLAIM, IN ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS GUARANTY OR ANY OTHER CREDIT DOCUMENT TO WHICH IT IS A PARTY BROUGHT IN ANY OF THE AFORESAID COURTS, THAT ANY SUCH COURT LACKS JURISDICTION OVER SUCH GUARANTOR. EACH GUARANTOR FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO EACH GUARANTOR AT ITS ADDRESS SET FORTH OPPOSITE ITS SIGNATURE BELOW, SUCH SERVICE TO BECOME EFFECTIVE 30 DAYS AFTER SUCH MAILING. EACH GUARANTOR HEREBY IRREVOCABLY WAIVES ANY OBJECTION TO SUCH SERVICE OF PROCESS AND FURTHER IRREVOCABLY WAIVES AND AGREES NOT TO PLEAD OR CLAIM IN ANY ACTION OR PROCEEDING COMMENCED HEREUNDER OR UNDER ANY OTHER CREDIT DOCUMENT TO WHICH SUCH GUARANTOR IS A PARTY THAT SERVICE OF PROCESS WAS IN ANY WAY INVALID OR INEFFECTIVE. NOTHING HEREIN SHALL AFFECT THE RIGHT OF ANY OF THE CREDITORS TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST EACH GUARANTOR IN ANY OTHER JURISDICTION.

(C) EACH GUARANTOR HEREBY IRREVOCABLY WAIVES ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY OF THE AFORESAID ACTIONS OR PROCEEDINGS ARISING OUT OF OR IN CONNECTION WITH THIS GUARANTY OR ANY OTHER CREDIT DOCUMENT BROUGHT IN THE COURTS REFERRED TO IN CLAUSE (B) ABOVE AND HEREBY FURTHER IRREVOCABLY WAIVES AND AGREES NOT TO PLEAD OR CLAIM IN ANY SUCH COURT THAT SUCH ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

(D) EACH GUARANTOR HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTER-

CLAIM ARISING OUT OF OR RELATING TO THIS GUARANTY, THE OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

21. In the event that all of the capital stock or other equity interests of one or more Guarantors is sold or otherwise disposed of (to a Person other than Holdings or a Subsidiary thereof) or liquidated in compliance with the requirements of Section 9.02 of the Credit Agreement (or such sale, disposition or liquidation has been approved in writing by the Required Lenders (or all Lenders if required by Section 13.12 of the Credit Agreement)) and the proceeds of such sale, disposition or liquidation are applied in accordance with the provisions of the Credit Agreement, to the extent applicable, such Guarantor shall be released from this Guaranty automatically and without further action and this Guaranty shall, as to each such Guarantor or Guarantors, terminate, and have no further force or effect (it being understood and agreed that the sale of one or more Persons that own, directly or indirectly, all of the capital stock or other Equity Interests of any Guarantor shall be deemed to be a sale of such Guarantor for the purposes of this Section 21).

22. All payments made by any Guarantor hereunder will be made without setoff, counterclaim or other defense.

23. This Guaranty may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which when so executed and delivered shall be an original, but all of which shall together constitute one and the same instrument. A set of counterparts executed by all the parties hereto shall be lodged with the Borrower and the Administrative Agent.

24. It is understood and agreed that any Subsidiary of Holdings that is required to execute a counterpart of this Guaranty after the date hereof pursuant to the Credit Agreement shall become a Guarantor hereunder by (x)(i) executing and delivering a counterpart hereof to the Administrative Agent or (ii) executing a joinder agreement in form and substance satisfactory to the Administrative Agent and delivering same to the Administrative Agent, in each case as may be requested by (and in form and substance satisfactory to) the Administrative Agent and (y) taking all actions as specified in this Guaranty as would have been taken by such Guarantor had it been an original party to this Guaranty, in each case with all documents and actions required to be taken to be taken above to the reasonable satisfaction of the Administrative Agent.

25. Notwithstanding anything else to the contrary in this Guaranty, the Creditors agree (by their acceptance of the benefits of this Guaranty) that this Guaranty may be enforced only by the action of the Administrative Agent or the Collateral Agent, in each case acting upon the instructions of the Required Lenders (or, after the date on which all Credit Document Obligations have been paid in full, the holders of at least a majority of the outstanding Other Obligations), and that no other Creditor shall have any right individually to seek to enforce or to enforce this Guaranty or to realize upon the security to be granted by the Security Documents, it being understood and agreed that such rights and remedies may be exercised by

the Administrative Agent or the Collateral Agent or the holders of at least a majority of the outstanding Other Obligations, as the case may be, for the benefit of the Creditors upon the terms of this Guaranty and the Security Documents. The Creditors further agree that this Guaranty may not be enforced against any director, officer, employee, or stockholder of any Guarantor (except to the extent such stockholder is also a Guarantor hereunder). It is understood that the agreement in this Section 25 is among and solely for the benefit of the Lenders and that if the Required Lenders so agree (without requiring the consent of any Guarantor), this Guaranty may be directly enforced by any Creditor.

26. At any time a payment in respect of the Guaranteed Obligations is made under this Guaranty, the right of contribution of each Guarantor hereunder against each other such Guarantor shall be determined as provided in the immediately following sentence, with the right of contribution of each Guarantor to be revised and restated as of each date on which a payment (a “Relevant Payment”) is made on the Guaranteed Obligations under this Guaranty. At any time that a Relevant Payment is made by a Guarantor that results in the aggregate payments made by such Guarantor hereunder in respect of the Guaranteed Obligations to and including the date of the Relevant Payment exceeding such Guarantor’s Contribution Percentage (as defined below) of the aggregate payments made by all Guarantors hereunder in respect of the Guaranteed Obligations to and including the date of the Relevant Payment (such excess, the “Aggregate Excess Amount”), each such Guarantor shall have a right of contribution against each other Guarantor who has made payments hereunder in respect of the Guaranteed Obligations to and including the date of the Relevant Payment in an aggregate amount less than such other Guarantor’s Contribution Percentage of the aggregate payments made to and including the date of the Relevant Payment by all Guarantors hereunder in respect of the Guaranteed Obligations (the aggregate amount of such deficit, the “Aggregate Deficit Amount”) in an amount equal to (x) a fraction the numerator of which is the Aggregate Excess Amount of such Guarantor and the denominator of which is the Aggregate Excess Amount of all Guarantors multiplied by (y) the Aggregate Deficit Amount of such other Guarantor. A Guarantor’s right of contribution pursuant to the preceding sentences shall arise at the time of each computation, subject to adjustment to the time of any subsequent computation; provided, that no Guarantor may take any action to enforce such right until the Guaranteed Obligations have been irrevocably paid in full in cash and the Total Commitment and all Letters of Credit have been terminated, it being expressly recognized and agreed by all parties hereto that any Guarantor’s right of contribution arising pursuant to this Guaranty against any other Guarantor shall be expressly junior and subordinate to such other Guarantor’s obligations and liabilities in respect of the Guaranteed Obligations and any other obligations owing under this Guaranty. As used in this Section 26: (i) each Guarantor’s “Contribution Percentage” shall mean the percentage obtained by dividing (x) the Adjusted Net Worth (as defined below) of such Guarantor by (y) the aggregate Adjusted Net Worth of all Guarantors; (ii) the “Adjusted Net Worth” of each Guarantor shall mean the greater of (x) the Net Worth (as defined below) of such Guarantor and (y) zero; and (iii) the “Net Worth” of each Guarantor shall mean the amount by which the fair salable value of such Guarantor’s assets on the date of any Relevant Payment exceeds its existing debts and other liabilities (including contingent liabilities, but without giving effect to any Guaranteed Obligations arising under this Guaranty or any guaranteed obligations arising under

any guaranty of the New Senior Subordinated Notes) on such date. All parties hereto recognize and agree that, except for any right of contribution arising pursuant to this Section 26, each Guarantor who makes any payment in respect of the Guaranteed Obligations shall have no right of contribution or subrogation against any other Guarantor in respect of such payment. Each of the Guarantors recognizes and acknowledges that the rights to contribution arising hereunder shall constitute an asset in favor of the party entitled to such contribution. In this connection, each Guarantor has the right to waive its contribution right against any Guarantor to the extent that after giving effect to such waiver such Guarantor would remain solvent, in the determination of the Required Lenders.

27. Each Guarantor and each Creditor (by its acceptance of the benefits of this Guaranty) hereby confirms that it is its intention that this Guaranty not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Code, the Uniform Fraudulent Conveyance Act or any similar Federal or state law. To effectuate the foregoing intention, each Guarantor and each Creditor (by its acceptance of the benefits of this Guaranty) hereby irrevocably agrees that the Guaranteed Obligations guaranteed by such Guarantor shall be limited to such amount as will, after giving effect to such maximum amount and all other (contingent or otherwise) liabilities of such Guarantor that are relevant under such laws (it being understood that it is the intention of the parties to this Guaranty and the parties to any guaranty of the New Senior Subordinated Notes that, to the maximum extent permitted under applicable laws, the liabilities in respect of the guarantees of the New Senior Subordinated Notes shall not be included for the foregoing purposes and that, if any reduction is required to the amount guaranteed by any Guarantor hereunder and with respect to the New Senior Subordinated Notes that its guarantee of amounts owing in respect of the New Senior Subordinated Notes shall first be reduced) and after giving effect to any rights to contribution pursuant to any agreement providing for an equitable contribution among such Guarantor and the other Guarantors, result in the Guaranteed Obligations of such Guarantor in respect of such maximum amount not constituting a fraudulent transfer or conveyance. Notwithstanding the provisions of the two preceding sentences, as between the Creditors and the holders of the New Senior Subordinated Notes, it is agreed (and the provisions of the New Senior Subordinated Notes Indenture so provide) that any diminution (whether pursuant to court decree or otherwise) of any Guarantor’s obligation to make any distribution or payment pursuant to this Guaranty shall have no force or effect for purposes of the subordination provisions contained in the New Senior Subordinated Notes Indenture, and that any payments received in respect of a Guarantor’s obligations with respect to the New Senior Subordinated Notes shall be turned over to the holders of the Guarantor Senior Debt (as defined in the New Senior Subordinated Notes Indenture) (or obligations which would have constituted Guarantor Senior Debt if same had not been reduced or disallowed) of such Guarantor (which Guarantor Senior Debt shall be calculated as if there were no diminution thereto pursuant to this Section 27 or for any other reason other than the irrevocable payment in full in cash of the respective obligations which would otherwise have constituted Guarantor Senior Debt) until all such Guarantor Senior Debt (or obligations which would have constituted Guarantor Senior Debt if same had not been reduced or disallowed) has been irrevocably paid in full in cash.

IN WITNESS WHEREOF, each Guarantor has caused this Guaranty to be executed and delivered as of the date first above written.
