THE GUARANTY.

2A.

Joint and Several Guaranty of Payment and Performance of Guaranteed Obligations.  Each Guarantor hereby 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, and the due and punctual performance, of all Guaranteed Obligations.  Each Guarantor hereby further agrees to pay and to indemnify and save each Holder harmless from and against any damage, loss, cost or expense (including reasonable attorneys’ fees) which such Holder may incur or be subject to as a consequence, direct or indirect, of endeavoring to enforce this Guaranty or to collect all or any part of the Guaranteed Obligations from, or in pursuing any action against, the Company or any Guarantor or enforcing any rights of any Holder in any security for the Guaranteed Obligations or the liabilities of each Guarantor hereunder, including, without limitation,  any taxes, fees or penalties which may be paid or payable in connection therewith.  This is a continuing guaranty of payment and performance and not only of collection.

All covenants, obligations, waivers, representations, warranties and agreements of each Guarantor under this Guaranty (whether or not elsewhere so stated) shall be joint and several.

Upon an Event of Default, the Required Holders may, at their sole election and without notice, proceed directly and at once against any Guarantor to seek and enforce performance of, and to collect and recover, the Guaranteed Obligations, or any portion thereof, without first proceeding against the Company or any other Person, or any other security for the Guaranteed Obligations or for the liability of any such other Person or Guarantor hereunder.

All payments made under this Guaranty shall be made ratably to each Holder in accordance with the amount of Guaranteed Obligations owed to such Holder as a proportion of the aggregate amount of all Guaranteed Obligations; provided, that each Holder shall have the exclusive right to determine the application of payments and credits, if any, received by it from any Guarantor.  This Guaranty and all covenants and agreements of the Guarantors contained herein shall continue in full force and effect and shall not be discharged until such a time as all of the Guaranteed Obligations shall be satisfied and indefeasibly paid in full in cash.






2















Notwithstanding any provision to the contrary contained herein, the obligations of each Guarantor hereunder shall be limited to an aggregate amount equal to the largest amount that would not render its obligations hereunder subject to avoidance under Section 548 of the “Bankruptcy Code” (as defined below) or any comparable provisions of any applicable state law.

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 Agreements, the Notes or any Other Agreement or any provision thereof; (ii) the absence of any attempt by any Holder to collect the Guaranteed Obligations or any portion thereof from the Company, any other guarantor of all or any portion of the Guaranteed Obligations or any other Person or to take any other action to enforce the same; (iii) any action taken by any Holder whether or not authorized by this Guaranty; (iv) any failure by any Holder to acquire, perfect or maintain any security interest or other Lien in, or take any steps to preserve its rights to, any other security for the Guaranteed Obligations or any portion thereof or for the liability of the Guarantors hereunder or the liability of any other guarantor of any or all of the Guaranteed Obligations; (v) any defense arising by reason of any disability or other defense (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 any 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 Guaranteed Obligations or any portion thereof; (vi) a Holder’s election, in any proceeding instituted under Chapter 11 of Title 11 of the Federal Bankruptcy Code (11 U.S.C. §101 et seq.) (the “Bankruptcy Code”), of the application of Section 1111(b)(2) of the Bankruptcy Code; (vii) any borrowing, or grant of a security interest to any Holder, by the Company, as debtor-in-possession, or extension of credit, under Section 364 of the Bankruptcy Code; (viii) the disallowance or avoidance of all or any portion of any Holder’s claim(s) for repayment of the Guaranteed Obligations under the Bankruptcy Code or any similar state law or the avoidance, invalidity or unenforceability of any Lien securing the Guaranteed Obligations or the liability of the Guarantors hereunder or of any other guarantor of all or any part of the Guaranteed Obligations; (ix) any amendment or supplement to, waiver or modification of, or consent, extension, indulgence or other action or inaction under or in respect of the Notes, the Note Purchase Agreements or any Other Agreement (including, without limitation, any increase in the interest rate on the Notes); (x) any change in any provision of any applicable law or regulation; (xi) any order, judgment, writ, award or decree of any court, arbitrator or governmental authority, domestic or foreign, binding on or affecting any of the Guarantors or the Company or any of their assets; (xii) the charter or by-laws of any of the Guarantors or the Company; (xiii) any mortgage, indenture, lease, contract, or other agreement (including, without limitation, any agreement with stockholders), instrument or undertaking to which any of the Guarantors or the Company is a party or which purports to be binding on or affect such Person or any of its assets; (xiv) any bankruptcy, insolvency, arrangement, readjustment, composition, liquidation, dissolution or similar proceeding with respect to the Company or any other guarantor of all or any portion of any Guaranteed Obligations or such Person’s property and any failure by any Holder to file or enforce a claim against the Company or such other Person in any such proceeding; (xv) 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 of the Guarantors; or (xvi) any other 






3















circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor or surety.

2C.

Obligations Unimpaired.  Each Holder is authorized, without demand or notice, which demand and notice are hereby waived, and without discharging or otherwise affecting the obligations of the Guarantors hereunder (which shall remain absolute and unconditional notwithstanding any such action or omission to act), from time to time to (i) renew, extend, accelerate or otherwise change the time for payment of, or other terms (including, without limitation interest rate terms) relating to, the Guaranteed Obligations or any portion thereof, or otherwise modify, amend or change the terms of the Note Purchase Agreements, the Notes or any of the Other Agreements; (ii) accept partial payments on the Guaranteed Obligations; (iii) take and hold security for the Guaranteed Obligations or any portion thereof or any other liabilities of the Company, the obligations of any of the Guarantors under this Guaranty and the obligations under any other guarantees and sureties of all or any of the Guaranteed Obligations, and exchange, enforce or waive any rights with respect to, release, sell, transfer, assign, abandon, fail to perfect its security interest in, subordinate or otherwise deal with, any such security; (iv) apply such security and direct the order or manner of sale thereof as such Holder may determine in its sole discretion; (v) settle, release, compromise, collect or otherwise liquidate the Guaranteed Obligations or any portion thereof and any security therefor or guaranty thereof in any manner; (vi) extend additional loans, credit and financial accommodations to the Company and otherwise create additional Guaranteed Obligations; (vii) waive strict compliance with the terms of the Note Purchase Agreements, the Notes or any of the Other Agreements and otherwise forbear from asserting such Holder’s rights and remedies thereunder; (viii) take and hold additional guaranties or sureties and enforce or forbear from enforcing any guaranty or surety of any other guarantor or surety of the Guaranteed Obligations or any portion thereof or release or otherwise take any action with respect to any such guarantor or surety; (ix) assign this Guaranty in part or in whole in connection with any assignment of the Guaranteed Obligations or any portion thereof; (x) exercise or refrain from exercising any rights against the Company; and (xi) apply any sums, by whomsoever paid or however realized, to the payment of the Guaranteed Obligations as such Holder in its sole discretion may determine.

2D.

Waivers of the Guarantors.  Each Guarantor waives for the benefit of each Holder:

(i)

any right to require any Holder, as a condition of payment or performance by any Guarantor or otherwise, to (a) proceed against the Company, any other guarantor of the Guaranteed Obligations or any other Person, (b) proceed against or exhaust any security given to or held by any Holder in connection with the Guaranteed Obligations or any other guaranty, or (c) pursue any other remedy available to any Holder whatsoever;

(ii)

any defense arising by reason of (a) the incapacity, lack of authority or any disability or other defense of the Company, including, without limitation, any defense based on or arising out of the lack of validity or the unenforceability of the Guaranteed Obligations or any agreement or instrument relating thereto, (b) the cessation of the liability of the Company from any cause other than indefeasible payment in full of the Guaranteed Obligations or (c) any act or omission of any Holder or any other Person which directly or indirectly, by operation of law or 






4















otherwise, results in or aids the discharge or release of the Company or any security given to or held by any Holder in connection with the Guaranteed Obligations or any other guaranty;

(iii)  any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal;

any defense based upon any Holder’s errors or omissions in the administration of the Guaranteed Obligations;

(v)

(a) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms of this Guaranty and any legal or equitable discharge of any of the Guarantors’ obligations hereunder, (b) the benefit of any statute of limitations affecting the Guaranteed Obligations or any of the Guarantors’ liability hereunder or the enforcement hereof, (c) any rights to setoffs, recoupments and counterclaims, and (d) promptness, diligence and any requirement that any Holder protect, maintain, perfect or insure any Lien or any property subject thereto;

No Guarantor will exercise any rights which it may have acquired by way of subrogation under this Guaranty, by any payment made hereunder or otherwise, or accept any payment on account of such subrogation rights, or any rights of reimbursement or indemnity or any rights or recourse to any security for the Guaranteed Obligations or this Guaranty unless at the time of the Guarantor’s exercise of any such right there shall have been performed and indefeasibly paid in full in cash all of the Guaranteed Obligations.
