Interest on the outstanding principal balance of this Note shall initially accrue and be due and payable in full immediately available funds to the Holder 90 days after the date hereof; thereafter, interest shall be due and payable in immediately available funds to the Holder upon the first (1^st) day of each calendar month through the Maturity Date.

Any amount of principal or interest on this Note which is not paid when due shall bear interest (“Default Interest”) at a rate equal to the lesser of the maximum rate permitted under applicable law or twenty-four percent (24.0%) per annum. Notwithstanding any other provision of this Note, all principal and accrued but unpaid interest shall, at the option of Holder, be due and payable in full upon the occurrence of an “Event of Default” as defined below. All payments shall be made at such address as the Holder shall hereafter give to the Company by written notice made in accordance with the provisions of this Note.

This Note is subject to the terms and conditions of that certain Credit Agreement dated as of the date hereof among the Company and Holder (the “Credit Agreement;” capitalized terms used herein but not otherwise defined shall have the meanings set forth in the Credit Agreement). This Note is secured as set forth in (a) the Security Agreement dated as of the date hereof among the Company and Holder and (b) guaranty agreements executed by affiliates and subsidiaries of the Company for the benefit of Holder.

The principal amount of this Note may not be paid before the Maturity Date without the prior written consent of the Holder, except as expressly set forth herein.

This Note is being issued pursuant to an exemption from registration under the Securities Act and the rules and regulations promulgated thereunder.

This Note is otherwise made on the following terms and conditions:

The occurrence of an “Event of Default” under the Credit Agreement shall constitute an Event of Default under this Note.

Upon the occurrence of an Event of Default, at the option of the Holder, this Note shall become immediately due and payable and the Company shall pay to the Holder an amount equal to the sum (the “Default Sum”) of (w) the then outstanding principal amount of this Note plus (x) accrued and unpaid interest on the unpaid principal amount of this Note to the date of payment (the “Default Payment Date”) plus (y) Default Interest, if any, on the amounts referred to in clauses (w) and (x), all without demand, presentment or notice, and all of which hereby are expressly waived, together with all costs, including, without limitation, legal fees and expenses, of collection. The Holder shall be entitled to exercise all other rights and remedies available at law or in equity.

This Note, together with the Credit Agreement, Security Agreement, and all other documents evidencing, securing or otherwise relating to the indebtedness evidenced hereby (collectively, the “Loan Documents”), constitute the entire agreement of the parties and

2

supersedes all prior agreements and undertakings, both written and oral, between the parties, or any of them, with respect to the subject matter hereof. This Note may not be modified, amended, supplemented, canceled or discharged, except by written instrument executed by the Company and the Holder. No failure to exercise, and no delay in exercising, any right, power or privilege under this Note shall operate as a waiver, nor shall any single or partial exercise of any right, power or privilege hereunder preclude the exercise of any other right, power or privilege. No waiver of any breach of any provision shall be deemed to be a waiver of any preceding or succeeding breach of the same or any other provision, nor shall any waiver be implied from any course of dealing between the Company and the Holder. No extension of time for performance of any obligations or other acts hereunder or under any other agreement shall be deemed to be an extension of the time for performance of any other obligations or any other acts.

The Company (and each entity constituting Company, jointly and severally) represents and warrants to Holder as follows:

(a) This Note and all other Loan Documents have been duly executed and delivered by the Company and constitute the legal, valid, binding and enforceable obligation of the Company, enforceable against Company in accordance with their terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally, the enforcement of creditors’ rights and remedies or by other equitable principles of general application.

(b) There are no state statutes or other “anti-takeover” laws applicable to the Company or to the issuance of this Note by the Company which would have, among other things, the effect of nullifying the transactions contemplated by this Note or the other Loan Documents, or, to the extent there are such applicable state statutes or other “anti-takeover” laws, the Company and its executive and management officers have taken all steps necessary under such statutes or laws to render them inapplicable to the Company and the issuance of this Note.

Nothing, herein contained, nor any transaction related hereto, shall be construed or so operate as to require the Company to pay interest at a greater rate than is now lawful in such case to contract for, or to make any payment, or to do any act contrary to law. Should any interest or other charges paid by the Company, or parties liable for the payment of this Note, in connection with the loan evidenced by this Note, or any document delivered in connection with said loan, result in the computation or earning of interest in excess of the maximum legal rate of interest which is legally permitted by law, then any and all such excess shall be and the same is hereby waived by the Holder hereof, and any and all such excess shall be automatically credited against and in reduction of the principal balance due under this Note, and the portion of said excess which exceeds the principal balance due under this Note shall be paid by the Holder to the Company.

The Holder shall be deemed to be the owner of this Note for all purposes, and the full payment of interest and principal under this Note to the Holder shall constitute the full and complete discharge of the Company for such purposes.

This Note and the rights, obligations and duties of the Company hereunder shall not be assignable or otherwise transferable by Company. The Holder may transfer or assign any or all

3

of its rights and obligations under this Note. In the event the Holder assigns or transfers this Note it shall, within a reasonable period of time thereafter, provide notice to the Company of such assignment or transfer; provided that, no failure of the Holder to provide such notice to the Company shall in any way impair the rights of the Holder under this Note or the effectiveness of the assignment.

No term or provision contained herein may be modified, amended or waived except by written agreement or consent signed by the party to be bound thereby.

This Note shall inure to the benefit of, and shall be binding upon, the parties hereto, their heirs, executors, administrators, personal representatives, successors in interest and permitted assigns.

In the event the Holder shall employ legal counsel to protect its rights hereunder or to enforce any term or provision hereof or under any of the Loan Documents, Company shall pay on demand all of Holder’s reasonable costs and expenses incurred in enforcing this Note and in preserving and liquidating the collateral encumbered by the Loan Documents, including but not limited to, reasonable arbitration, paralegals’, attorneys’ and experts’ fees and expenses, whether incurred with or without the commencement of a suit, trial, arbitration, or administrative proceeding, or in any appellate or bankruptcy proceeding.

Company agrees that from time to time hereafter, upon request, it will, at its sole expense, execute, acknowledge and deliver such other instruments and documents and take such further action as may be reasonably necessary to carry out the intent of this Note and the Loan Documents.

The enumeration of the Holder’s rights and remedies set forth in this Note is not intended to be exhaustive and the exercise by the Holder of any right or remedy shall not preclude the exercise of any other rights or remedies, all of which shall be cumulative, and shall be in addition to any other right or remedy given hereunder, under the Loan Documents or under any other agreement between the Company and the Holder or which may now or hereafter exist in law or in equity or by suit or otherwise. No delay or failure to take action on the part of the Holder in exercising any right, power or privilege shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or privilege preclude other or further exercise thereof or the exercise of any other right, power or privilege or shall be construed to be a waiver of any Event of Default. No course of dealing between the Company and the Holder or the Holder’s employees shall be effective to change, modify or discharge any provision of this Note or to constitute a waiver of any Event of Default.

All of the foregoing losses, damages, costs and expenses of the Holder shall be payable by the Company upon demand by the Holder.
