WHEREAS, each of the Existing Guarantors, the Company and each other Guarantor are or will be mutually dependent on each other in the conduct of their respective businesses as an integrated operation, with the credit needed from time to time by one often being provided through financing obtained by the other and the ability to obtain such financing being dependent on the successful operations of each of the Existing Guarantors, the Company and each other Guarantor.

NOW, THEREFORE, in consideration of the premises and the agreements herein and for other consideration, the sufficiency of which is hereby acknowledged, each Guarantor hereby agrees with the Buyer as follows:

SECTION 1. Definitions. Reference is hereby made to the Note for a statement of the terms thereof. All terms used in this Guaranty, which are defined in the Note and not otherwise defined herein, shall have the same meanings herein as set forth therein.

SECTION 2. Guaranty. The Guarantors, jointly and severally, hereby unconditionally and irrevocably, guaranty (a) the punctual payment, as and when due and payable, by stated maturity or otherwise, of all obligations and any other amounts now or hereafter owing by the Company in respect of it in respect of the Note and the other Note Transaction Documents, including, without limitation, all interest that accrues after the commencement of any proceeding commenced by or against any the Company or any Guarantor under any provision of the Bankruptcy Code (Chapter 11 of Title 11 of the United States Code) or under any other bankruptcy or insolvency law, assignments for the benefit of creditors, formal or informal moratoria, compositions, or extensions generally with creditors, or proceedings seeking reorganization, arrangement, or other similar relief (an "Insolvency Proceeding"), whether or not the payment of such interest is unenforceable or is not allowable due to the existence of such Insolvency Proceeding, and any and all expenses (including reasonable counsel fees and expenses) reasonably incurred by the Buyer in enforcing any rights under this Guaranty (such obligations, to the extent not paid by the Company, being the "Guaranteed Obligations") and (b) the punctual and faithful performance, keeping, observance and fulfillment by the Company of all of the agreements, conditions, covenants and obligations of the Company contained in the Note and the other Note Transaction Documents. Without limiting the generality of the foregoing, each Guarantor's liability hereunder shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by the Company to the Buyer under the Note but for the fact that they are unenforceable or not allowable due to the existence of an Insolvency Proceeding involving any Guarantor or the Company (each, a "Transaction Party").

SECTION 3.       Guaranty Absolute; Continuing Guaranty; Assignments.

(a)         The Guarantors, jointly and severally, guaranty that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Note Transaction Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Buyer with respect thereto. The obligations of each Guarantor under this Guaranty are independent of the Guaranteed Obligations, and a separate action or actions may be brought and prosecuted against any Guarantor to enforce such obligations, irrespective of whether any action is brought against any Transaction Party or whether any Transaction Party is joined in any such action or actions. The liability of any Guarantor under this Guaranty shall be irrevocable, absolute and unconditional irrespective of, and each Guarantor hereby irrevocably waives, to the extent permitted by law, any defenses it may now or hereafter have in any way relating to, any or all of the following:

(i)          any lack of validity or enforceability of any Note Transaction Document or any agreement or instrument relating thereto;

(ii)         any change in the time, manner or place of payment of, or in any other term of, all or any of the Guaranteed Obligations, or any other amendment or waiver of or any consent to departure from any Note Transaction Document, including, without limitation, any increase in the Guaranteed Obligations resulting from the extension of additional credit to any Transaction Party or otherwise;

(iii)        any taking, exchange, release or non-perfection of any collateral with respect to the Guaranteed Obligations, or any taking, release or amendment or waiver of or consent to departure from any other guaranty, for all or any of the Guaranteed Obligations; or

(iv)        any change, restructuring or termination of the corporate, limited liability company or partnership structure or existence of any Transaction Party.

This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations is rescinded or must otherwise be returned by the Buyer or any other Person upon the insolvency, bankruptcy or reorganization of any Transaction Party or otherwise, all as though such payment had not been made.

(b)          This Guaranty is a continuing guaranty and shall (i) remain in full force and effect until the indefeasible payment in full in cash of all obligations under the Note (together with any matured indemnification obligations as of the date of such payment, but excluding any inchoate or unmatured contingent indemnification obligations) and payment of all other amounts payable under this Guaranty (excluding any inchoate or unmatured contingent indemnification obligations) and (ii) be binding upon each Guarantor and its respective successors and assigns. This Guaranty shall inure to the benefit of and be enforceable by the Buyer and its respective successors, and permitted pledgees, transferees and assigns. Without limiting the generality of the foregoing sentence, the Buyer may pledge, assign or otherwise transfer all or any portion of its rights and obligations under and subject to the terms of any Note Transaction Document to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to the Buyer herein or otherwise, in each case as provided in the other Note Transaction Document.

SECTION 4.          Waivers. To the extent permitted by applicable law, each Guarantor hereby waives promptness, diligence, notice of acceptance and any other notice with respect to any of the Guaranteed Obligations and this Guaranty and any requirement that the Buyer exhausts any right or takes any action against any Transaction Party or any other Person or any Collateral (as defined in the Security Agreement). Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated herein and that the waiver set forth in this Section 4 is knowingly made in contemplation of such benefits. The Guarantors hereby waive any right to revoke this Guaranty, and acknowledge that this Guaranty is continuing in nature and applies to all Guaranteed Obligations, whether existing now or in the future.

SECTION 5.         Subrogation. No Guarantor may exercise any rights that it may now or hereafter acquire against any Transaction Party or any other guarantor that arise from the existence, payment, performance or enforcement of any Guarantor's obligations under this Guaranty, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of the Buyer against any Transaction Party or any other guarantor or any Collateral (as defined in the Security Agreement), whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from any Transaction Party or any other guarantor, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security solely on account of such claim, remedy or right, unless and until the indefeasible payment in full in cash of all obligations under the Note (together with any matured indemnification obligations as of the date of such payment, but excluding any inchoate or unmatured contingent indemnification obligations) and payment of all other amounts payable under this Guaranty (excluding any inchoate or unmatured contingent indemnification obligations). If any amount shall be paid to a Guarantor in violation of the immediately preceding sentence at any time prior to the later of the payment in full in cash of the Guaranteed Obligations and all other amounts payable under this Guaranty, such amount shall be held in trust for the benefit of the Buyer and shall forthwith be paid to the Buyer to be credited and applied to the Guaranteed Obligations and all other amounts payable under this Guaranty, whether matured or unmatured, in accordance with the terms of the Note Transaction Document, or to be held as collateral for any Guaranteed Obligations or other amounts payable under this Guaranty thereafter arising. If (a) any Guarantor shall make payment to the Buyer of all or any part of the Guaranteed Obligations, and (b) the Buyer receives the indefeasible payment in full in cash of all obligations under the Note (together with any matured indemnification obligations as of the date of such payment, but excluding any inchoate or unmatured contingent indemnification obligations) and payment of all other amounts payable under this Guaranty (excluding any inchoate or unmatured contingent indemnification obligations), the Buyer will, at such Guarantor's request and expense, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Guaranteed Obligations resulting from such payment by such Guarantor.

Upon the occurrence and during the continuance of any Event of Default, the Buyer may, and is hereby authorized to, at any time and from time to time, without notice to the Guarantors (any such notice being expressly waived by each Guarantor) and to the fullest extent permitted by law, set-off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by the Buyer to or for the credit or the account of any Guarantor against any and all obligations of the Guarantors now or hereafter existing under this Guaranty or any other Note Transaction Document, irrespective of whether or not the Buyer shall have made any demand under this Guaranty or any other Note Transaction Document and although such obligations may be contingent or unmatured. The Buyer agrees to notify the relevant Guarantor promptly after any such set-off and application made by the Buyer, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Buyer under this Section 7 are in addition to other rights and remedies (including, without limitation, other rights of set-off) which the Buyer may have under this Guaranty or any other Note Transaction Document in law or otherwise.

SECTION 11.        Taxes.

(a)        All payments made by any Guarantor hereunder or under any other Note Transaction Document shall be made in accordance with the terms of the respective Note Transaction Document and shall be made without set-off, counterclaim, deduction or other defense. All such payments shall be made free and clear of and without deduction for any present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding taxes imposed on the net income of the Buyer by the jurisdiction in which the Buyer is organized or where it has its principal lending office (all such nonexcluded taxes, levies, imposts, deductions, charges, withholdings and liabilities, collectively or individually, "Taxes"). If any Guarantor shall be required to deduct or to withhold any Taxes from or in respect of any amount payable hereunder or under any other Note Transaction Document:

(i)          the amount so payable shall be increased to the extent necessary so that after making all required deductions and withholdings (including Taxes on amounts payable to the Buyer pursuant to this sentence) the Buyer receives an amount equal to the sum it would have received had no such deduction or withholding been made,

(ii)         such Guarantor shall make such deduction or withholding,

(iii)        such Guarantor shall pay the full amount deducted or withheld to the relevant taxation authority in accordance with applicable law, and

(iv)        as promptly as possible thereafter, such Guarantor shall send the Buyer an official receipt (or, if an official receipt is not available, such other documentation as shall be satisfactory to the Buyer) showing payment.  In addition, each Guarantor agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or from the execution, delivery, registration or enforcement of, or otherwise with respect to, this Agreement or any other Note Transaction Document (collectively, "Other Taxes").

(b)         Each Guarantor hereby indemnifies and agrees to hold the Buyer harmless from and against Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 11) paid by the Buyer as a result of any payment made hereunder or from the execution, delivery, registration or enforcement of, or otherwise with respect to, this Agreement or any other Note Transaction Document, and any liability (including penalties, interest and expenses for nonpayment, late payment or otherwise) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted.  This indemnification shall be paid within 30 days from the date on which the Holder makes written demand therefor, which demand shall identify the nature and amount of such Taxes or Other Taxes.

(c)        If any Guarantor fails to perform any of its obligations under this Section 11, such Guarantor shall indemnify the Buyer for any taxes, interest or penalties that may become payable as a result of any such failure. The obligations of the Guarantors under this Section 11 shall survive the termination of this Guaranty and the payment of the Obligations and all other amounts payable hereunder.

SECTION 12.        Miscellaneous.

(a)        Each Guarantor will make each payment hereunder in lawful money of the United States of America and in immediately available funds to Buyer, at such address specified by Buyer from time to time by notice to the Guarantors.

(b)        No amendment or waiver of any provision of this Guaranty and no consent to any departure by any Guarantor therefrom shall in any event be effective unless the same shall be in writing and signed by each Guarantor and the Buyer, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

(c)        No failure on the part of the Buyer to exercise, and no delay in exercising, any right hereunder or under any other Note Transaction Document shall operate as a waiver thereof, nor shall any single or partial exercise of any right hereunder or under any Note Transaction Document preclude any other or further exercise thereof or the exercise of any other right. The rights and remedies of the Buyer provided herein and in the other Note Transaction Documents are cumulative and are in addition to, and not exclusive of, any rights or remedies provided by law. The rights of the Buyer under any Note Transaction Document against any party thereto are not conditional or contingent on any attempt by the Buyer to exercise any of its rights under any other Note Transaction Document against such party or against any other Person.

(d)        Any provision of this Guaranty that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining portions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.

(e)        This Guaranty shall (i) be binding on each Guarantor and its respective successors and assigns, and (ii) inure, together with all rights and remedies of the Buyer hereunder, to the benefit of the Buyer and its successors, transferees and assigns. Without limiting the generality of clause (ii) of the immediately preceding sentence, the Buyer may assign or otherwise transfer its rights and obligations under the Note or any other Note Transaction Document to any other Person in accordance with the terms thereof, and such other Person shall thereupon become vested with all of the benefits in respect thereof granted to the Buyer herein or otherwise. None of the rights or obligations of any Guarantor hereunder may be assigned or otherwise transferred without the prior written consent of the Buyer.

(f)        This Guaranty reflects the entire understanding of the transaction contemplated hereby and shall not be contradicted or qualified by any other agreement, oral or written, entered into before the date hereof.

(g)        Section headings herein are included for convenience of reference only and shall not constitute a part of this Agreement for any other purpose.

(h)        This Guaranty shall be governed by and construed in accordance with the law of the State of New York applicable to contracts made and to be performed therein without regard to conflict of law principles.

(i)        Each Guarantor hereby acknowledges and agrees that this Guaranty shall amend, restate, modify, extend, renew and continue the terms and provisions contained in the Existing Guaranty and shall not extinguish or release such Guarantor from any liability under such Existing Guaranty or otherwise constitute a novation of the obligations (including, without limitation, the Guaranteed Obligations (as defined in the Existing Guaranty)) thereunder.

(j)        By its execution and delivery of this Guaranty, the Company and its Subsidiaries hereby agree and covenant (i) to do each of the things set forth in the Note that I/P agrees and covenants to use its commercially reasonably efforts to cause the Company and its Subsidiaries to do, (ii) to not do each of the things set forth in the Note that I/P agrees and covenants to use its commercially reasonably efforts to cause the Company and its Subsidiaries not to do, in each case, fully as though the Company and its Subsidiaries were a party thereto, and such agreements and covenants are incorporated herein by this reference, mutatis mutandis, and (iii) all payments due under this Guaranty shall be senior to all other Indebtedness of the Company and its Subsidiaries other than Permitted Senior Indebtedness.
