ARTICLE I
THE GUARANTY

          1.1 The Guaranty. Guarantors, individually and not jointly, for themselves, their successors and assigns, hereby unconditionally and absolutely guarantee Lender the full and complete payment and performance when due (whether at stated maturity, by acceleration or otherwise) of each of the Obligations. This is a guaranty of payment and performance and not of collection.

          1.2 Waivers and Consents.  (a) Guarantors acknowledges that the obligations undertaken herein involve the guaranty of obligations of a Person other than Guarantors and, in full recognition of that fact, Guarantors consents and agrees that Lender may, at any time and from time to time, without notice or demand, and without affecting the enforceability or continuing effectiveness hereof: (i) supplement, modify, amend, extend, renew, accelerate or otherwise change the time for payment or the other terms of the Obligations or any part thereof, including without limitation any increase or decrease of the principal amount thereof or the rate(s) of interest thereon; (ii) supplement, modify, amend or waive, or enter into or give any agreement, approval or consent with respect to, the Obligations or any part thereof, or any of the Loan Documents or any additional security or guaranties, or any condition, covenant, default, remedy, right, representation or term thereof or thereunder; (iii) accept new or additional instruments, documents or agreements in exchange for or relative to any of the Loan Documents or the Obligations or any part thereof; (iv) accept partial payments on the Obligations; (v) receive and hold additional security or guaranties for the Obligations or any part thereof; (vi) release, reconvey, terminate, waive, abandon, fail to perfect, subordinate, exchange, substitute, transfer and/or enforce any security or guaranties, and apply any security and direct the order or manner of sale thereof as Lender in its sole and absolute discretion may determine; (vii) release any Person from any personal liability with respect to the Obligations or any part thereof; (viii) settle, release on terms satisfactory to Lender or by operation of applicable law or otherwise, liquidate or enforce any Obligations and any security or guaranty in any manner, consent to the transfer of any security and bid and purchase at any sale; and/or (ix) consent to the merger, change or any other restructuring or termination of the corporate existence of either Borrower or any other Person, and correspondingly restructure the Obligations, and any such merger, change, restructuring or termination shall not affect the liability of Guarantors or the continuing effectiveness hereof, or the enforceability hereof with respect to all or any part of the Obligations.

               (b) Upon the occurrence and during the continuance of any Event of Default, Lender may enforce this Guaranty independently of any other remedy, guaranty or security the Lender at any time may have or hold in connection with the Obligations, and it shall not be necessary for the Lender to marshal assets in favor of the Borrowers, any other guarantor of the Obligations or any other Person or to proceed upon or against and/or exhaust any security or remedy before proceeding to enforce this Guaranty.

Lender may file a separate action or actions against Guarantors, whether action is brought or prosecuted with respect to any security or against any other Person, or whether any other Person is joined in any such action or actions. Guarantors agrees that Lender and Borrowers may deal with each other in connection with the Obligations or otherwise, or alter any contracts or agreements now or hereafter existing between them, in any manner whatsoever, all without in any way altering or affecting the security of this Guaranty.

               (c) The Lender’s rights hereunder shall be reinstated and revived, and the enforceability of this Guaranty shall continue, with respect to any amount at any time paid on account of the Obligations which thereafter shall be required to be restored or returned by Lender upon the bankruptcy, insolvency or reorganization of any Person, all as though such amount had not been paid. The rights of Lender created or granted herein and the enforceability of this Guaranty shall remain effective at all times until the Termination Date to guarantee the full amount of all the Obligations even though the Obligations, including any part thereof or any other security or guaranty therefor, may be or hereafter may become invalid or otherwise unenforceable as against the Borrowers or any other guarantor of the Obligations and whether or not the Borrowers or any other guarantor of the Obligations shall have any personal liability with respect thereto.

               (d) Guarantors expressly waives, to the fullest extent permitted by applicable law, any and all defenses now or hereafter arising or asserted by reason of: (i) any disability or other defense of the Borrowers or any other guarantor for the Obligations with respect to the Obligations; (ii) the unenforceability or invalidity of any security for or guaranty of the Obligations or the lack of perfection or continuing perfection or failure of priority of any security for the Obligations; (iii) the cessation for any cause whatsoever of the liability of the Borrowers or any other guarantor of the Obligations (other than by reason of the full payment and performance of all Obligations (other than contingent indemnification obligations)); (iv) any failure of Lender to marshal assets in favor of the Borrowers or any other Person; (v) any failure of the Lender to give notice of sale or other disposition of collateral to the Borrowers or any other Person or any defect in any notice that may be given in connection with any sale or disposition of collateral; (vi) any failure of Lender to comply with applicable Laws in connection with the sale or other disposition of any collateral or other security for any Obligation, including, without limitation, any failure of Lender to conduct a commercially reasonable sale or other disposition of any collateral or other security for any Obligation; (vii) any act or omission of Lender or others that directly or indirectly results in or aids the discharge or release of either Borrower or any other guarantor of the Obligations, or of any security or guaranty therefor by operation of law or otherwise; (viii) any law which provides that the obligation of a surety or guarantor must neither be larger in amount nor in other respects more burdensome than that of the principal or which reduces a

surety’s or guarantor’s obligation in proportion to the principal obligation; (ix) any failure of Lender to file or enforce a claim in any bankruptcy or other proceeding with respect to any Person; (x) the election by Lender, in any bankruptcy proceeding of any Person, of the application or non-application of Section 1111(b)(2) of the United States Bankruptcy Code; (xi) any extension of credit or the grant of any lien under Section 364 of the United States Bankruptcy Code; (xii) any use of collateral under Section 363 of the United States Bankruptcy Code; (xiii) any agreement or stipulation with respect to the provision of adequate protection in any bankruptcy proceeding of any Person; (xiv) the avoidance of any lien or security interest in favor of Lender for any reason; (xv) any bankruptcy, insolvency, reorganization, arrangement, readjustment of debt, liquidation or dissolution proceeding commenced by or against any Person, including without limitation any discharge of, or bar or stay against collecting, all or any of the Obligations (or any interest thereon) in or as a result of any such proceeding; or (xvi) any action taken by Lender that is authorized by this Section or any other provision of any Loan Document. Guarantors expressly waive all setoffs and counterclaims and all presentments, demands for payment or performance, notices of nonpayment or nonperformance, protests, notices of protest, notices of dishonor and all other notices or demands of any kind or nature whatsoever with respect to the Obligations, and all notices of acceptance of this Guaranty or of the existence, creation or incurrence of new or additional Obligations.

          1.3 Condition of Borrowers.  Guarantor represents and warrants to Lender that it has established adequate means of obtaining from the Borrowers, on a continuing basis financial and other information pertaining to the businesses, operations and condition (financial and otherwise) of the Borrowers and their assets and properties. Each Guarantor hereby expressly waives and relinquishes any duty on the part of Lender (should any such duty exist) to disclose to such Guarantor any matter, fact or thing related to the business, operations or condition (financial or otherwise) of the Borrowers or their assets or properties, whether now known or hereafter known by Lender during the life of this Guaranty. With respect to any of the Obligations, Lender need not inquire into the powers of the Borrowers or agents acting or purporting to act on their behalf, and all Obligations made or created in good faith reliance upon the professed exercise of such powers shall be guaranteed hereby.

          1.4 Continuing  Guaranty.  This is a continuing guaranty and shall remain in full force and effect as to all of the Obligations until such date as all amounts owing by Borrowers to Lender on the Obligations shall have been paid in full in cash and all commitments of the Lender to lend under the Credit Agreement have terminated or expired and all obligations of Lender with respect to any of the Obligations shall have terminated or expired (such date is referred to herein as the “Termination Date”).

          1.5 Subrogation; Subordination.  Until the Termination Date each Guarantor expressly suspends any claim for reimbursement, contribution, indemnity or subrogation which such Guarantor may have against the Borrowers as a guarantor of the Obligations and any other legal or equitable claim against the Borrowers arising out of the payment of the Obligations by such Guarantor or from the proceeds of any collateral for this Guaranty, until all amounts owing to Lender under the Obligations (other than contingent indemnification obligations) shall have been paid in full and all commitments to lend have been terminated or expired. In furtherance, and not in limitation, of the foregoing waiver, each Guarantor hereby agrees that no payment by such Guarantor pursuant to this Guaranty shall constitute such Guarantor a creditor of the Borrowers. Until the Termination Date each Guarantor shall not seek any reimbursement from the Borrowers in respect of payments made by such Guarantor in connection with this Guaranty, or in respect of amounts realized by Lender in connection with any collateral for the Obligations, and such Guarantor expressly suspends any right to enforce any remedy that Lender now have or hereafter may have against any other Person and suspends the benefit of, or any right to participate in, any collateral now or hereafter held by Lender. No claim which any Guarantor may have against any other guarantor of any of the Obligations or against the Borrowers, to the extent not suspended pursuant to this Section, shall be enforced nor any payment accepted until the Termination Date and all such payments are not subject to any right of recovery.
