The recitals in this Guaranty are incorporated into this Guaranty. 2. THE GUARANTY. 2A. Guaranty of Payment. Each Guarantor, jointly and severally, absolutely, unconditionally and irrevocably guarantees the full and prompt payment in United States currency when due (whether at maturity, a stated prepayment date or earlier by reason of acceleration or otherwise) and at all times thereafter, of all of the indebtedness, existing on the date hereof or arising from time to time hereafter, whether direct or indirect, joint or several, actual, absolute or contingent, matured or unmatured, liquidated or unliquidated, secured or unsecured, arising by contract, operation of law or otherwise, of the Company to any Noteholder under or in respect of the Note Purchase Agreement and the Notes, including, without limitation, the principal of and interest (including, without limitation, interest accruing before, during or after any bankruptcy, insolvency, reorganization, arrangement, readjustment of debt, liquidation or dissolution proceeding, and, if interest ceases to accrue by operation of law by reason of any such proceeding, interest which otherwise would have accrued in the absence of such proceeding, whether or not allowed as a claim in such proceeding) on the Notes or any Make-Whole Amount (collectively, the "Guarantied Obligations").

Upon an Event of Default, any Noteholder may, at its sole election and without notice, proceed directly and at once against any Guarantor to seek and enforce payment of, and to collect and recover, the Guarantied Obligations, or any portion thereof, without first proceeding against the Company, any other Guarantor or any other Person or against any security for the Guarantied Obligations or for the liability of any such other Person or the Guarantor hereunder. Each Noteholder shall have the exclusive right to determine the application of payments and credits, if any, to such Noteholder from each Guarantor, the Company or from any other Person on account of the Guarantied Obligations or otherwise. This Guaranty and all covenants and agreements of each Guarantor contained herein shall continue in full force and effect and shall not be discharged until such a time as all of the Guarantied Obligations shall be indefeasibly paid in full in cash. 2B. Obligations Unconditional. The obligations of each Guarantor under this Guaranty shall be continuing, absolute and unconditional, irrespective of (i) the invalidity or unenforceability of the Note Purchase Agreement, the Notes or any other agreements, documents, certificates and instruments now or hereafter executed or delivered by the Company or any other Guarantor or any other Person in connection with the Note Purchase Agreement or any provision thereof; (ii) the absence of any attempt by any Noteholder to collect the Guarantied Obligations or any portion thereof from the Company, any other Guarantor or any other Person or other action to enforce the same; (iii) any failure by any Noteholder to acquire, perfect or maintain any security interest or lien in, or take any steps to preserve its rights to, any security for the Guarantied Obligations or any portion thereof or for the liability of any Guarantor hereunder or the liability of the Company, any other Guarantor or any other Person or any or all of the Guarantied Obligations; (iv) any defense arising by reason of any disability (other than a defense of payment, unless the payment on which such defense is based was or is subsequently invalidated, declared to be fraudulent or preferential, otherwise avoided and/or required to be repaid to the Company or a Guarantor, as the case may be, or the estate of any such party, a trustee, receiver or any other Person under any bankruptcy law, state or federal law, common law or equitable cause, in which case there shall be no defense of payment with respect to such payment) of the Company or any other Person liable on the Guarantied Obligations or any portion thereof; (v) any Noteholder's election, in any proceeding instituted under Chapter 11 of Title 11 of the Federal Bankruptcy Code (11 U.S.C. ss.101 et seq.) (the "Bankruptcy Code"), of the application of Section 1111(b)(2) of the Bankruptcy Code; (vi) any borrowing or grant of a security interest to any Noteholder by the Company as debtor-in-possession, or extension of credit, under Section 364 of the Bankruptcy Code; (vii) the disallowance or avoidance of all or any portion of any Noteholder's claim(s) for repayment of the Guarantied Obligations under the Bankruptcy Code or any similar state law or the avoidance, invalidity or unenforceability of any Lien securing the Guarantied Obligations or the liability of any Guarantor hereunder or of the Company or any other guarantor of all or any part of the Guarantied Obligations; (viii) any amendment to, waiver or modification of, or consent, extension, indulgence or other action or inaction under or in respect of the Note Purchase Agreement, the Notes or any other agreements, documents, certificates and instruments now or hereafter executed or delivered by the Company or any Guarantor or any other guarantor in connection with the Note Purchase Agreement (including, without limitation, any increase in the interest rate on the Notes); (ix) any change in any provision of any applicable law or regulation; to the extent the same may be waived under any such applicable law or regulation; (x) any order, judgment, writ, award or decree of any court, arbitrator or governmental authority, domestic or foreign, binding on or affecting any Guarantor, the Company or any other guarantor or any of their assets; (xi) the certificate of incorporation or articles of organization (as the case may be), or the by-laws or limited liability company agreement (as the case may be) of any Guarantor or the Company or any other guarantor; (xii) any mortgage, indenture, lease, contract, or other agreement (including without limitation any agreement with stockholders), instrument or undertaking to which any Guarantor or the Company is a party or which purports to be binding on or affect any such Person or any of its assets; (xiii) any bankruptcy, insolvency, readjustment, composition, liquidation or similar proceeding with respect to the Company, any Guarantor or any other guarantor of all or any portion of any Guarantied Obligations or any such Person's property and any failure by any Noteholder to file or enforce a claim against the Company, any Guarantor or any such other Person in any such proceeding; (xiv) any failure on the part of the Company for any reason to comply with or perform any of the terms of any other agreement with any Guarantor; or (xv) any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor (other than a defense of payment, unless the payment on which such defense is based was or is subsequently invalidated, declared to be fraudulent or preferential, otherwise avoided and/or required to be repaid to the Company or a Guarantor, as the case may be, or the estate of any such party, a trustee, receiver or any other Person under any bankruptcy law, state or federal law, common law or equitable cause, in which case there shall be no defense of payment with respect to such payment). 2C. Obligations Unimpaired.
