W I T N E S S E T H

          WHEREAS, the Company and the other Guarantors party thereto have heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of August 12, 2005 providing for the issuance of the Company’s 9 1/4% Senior Subordinated Notes due 2013 (the “Notes”);

          WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall, subject to Article Twelve of the Indenture, unconditionally guarantee the Notes on the terms and conditions set forth therein (the “Note Guarantee”); and

          WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

          NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Company, the Guarantors, the Guaranteeing Subsidiary and the Trustee agree as follows for the equal and ratable benefit of the Holders of the Notes:

          1. Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

          2. Agreement to Guarantee.

          (a) Subject to Article Twelve of the Indenture, the Guaranteeing Subsidiary, jointly and severally with all other Guarantors, fully and unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:

     (i) the principal of, premium, if any, and accrued and unpaid interest and Additional Interest, if any, on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium, if any, and interest and Additional Interest, if any, on the Notes, if

lawful (subject in all cases to any applicable grace period provided herein), and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full, all in accordance with the terms hereof and thereof; and

     (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the same will be promptly paid in full when due in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. The Guaranteeing Subsidiary agrees that this is a guarantee of payment and not a guarantee of collection.

          (b) The Guaranteeing Subsidiary hereby agrees that, to the maximum extent permitted under applicable law, its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor.

          (c) The Guaranteeing Subsidiary, subject to Section 6.06 of the Indenture, hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Note Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and the Indenture.

          (d) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors, or any custodian, trustee, liquidator or other similar official acting in relation to any of the Company or the Guarantors, any amount paid by any of them to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

          (e) The Guaranteeing Subsidiary agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby.

          (f) The Guaranteeing Subsidiary agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six of the Indenture for the purposes of the Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article Six of the Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of the Note Guarantee.

          (g) The Guaranteeing Subsidiary shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

          (h) The Guaranteeing Subsidiary confirms, pursuant to Section 12.02 of the Indenture, that it is the intention of such Guaranteeing Subsidiary that the Note Guarantee not constitute (i) a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to the Note Guarantee or (ii) an unlawful distribution under any applicable state law prohibiting shareholder distributions by an insolvent subsidiary to the extent applicable to the Note Guarantee. To effectuate the foregoing intention, the Guaranteeing Subsidiary and the Trustee hereby irrevocably agree that the obligations of the Guaranteeing Subsidiary will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guaranteeing Subsidiary that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under Article Twelve of the Indenture, result in the obligations of the Guaranteeing Subsidiary under the Note Guarantee not constituting a fraudulent transfer or conveyance or such an unlawful shareholder distribution.

          3. Execution and Delivery. The Guaranteeing Subsidiary agrees that the Note Guarantee shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of the Note Guarantee.

          4. Guaranteeing Subsidiary May Consolidate, Etc., on Certain Terms. The Guaranteeing Subsidiary may not sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into, any Person other than as set forth in Section 12.04 of the Indenture.

          5. Release. The Guaranteeing Subsidiary’s Note Guarantee shall be released as set forth in Section 12.05 of the Indenture.

          6. No Recourse Against Others. Pursuant to Section 14.07 of the Indenture, no director, officer, employee, incorporator or stockholder of the Guaranteeing Subsidiary shall have any liability for any obligations of the Guaranteeing Subsidiary under the Notes, the Indenture, this Supplemental Indenture, the Note Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. This waiver and release are part of the consideration for the Note Guarantee.

          7. Subordination of Note Guarantee. Payments on the Note Guarantees are subordinated to the extent and manner provided for in Article 13 of the Indenture, to the prior payment in full in cash or Cash Equivalents of all Senior Debt of the Guarantors, including Senior Debt of the Guarantors incurred after the date of the Indenture.
