 W I T N E S S E T H 
 WHEREAS, each of the Issuers
and the Guarantors (as defined in the Indenture referred to below) has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of December 1, 2005, as heretofore amended, providing for the
issuance of an unlimited aggregate principal amount of 10 1/8% Senior Notes due 2013 and Senior Floating Rate Notes due 2013
(together, the “Notes”); 
 WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing
Subsidiaries shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiaries shall unconditionally guarantee all of the Issuers’ Obligations under the Notes and the Indenture on the terms and
conditions set forth herein and under the Indenture (the “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 parties mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows: 
 (1)        Capitalized Terms.  Capitalized terms used herein without definition shall have the
meanings assigned to them in the Indenture. 
 (2)        Agreement to
Guarantee.  Each Guaranteeing Subsidiary hereby agrees as follows: 
 (a)        Along with all other Guarantors named in the Indenture, to jointly and severally unconditionally guarantee 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 Issuers hereunder or thereunder, that: 
 (i)        the principal of and interest, premium 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 and interest on the Notes, if any, if lawful, and all other obligations of the Issuers to the Holders or
the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
  

 1 








 (ii)        in case of any extension of time of
payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed 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 or any performance so guaranteed for whatever reason, the Guarantors and the Guaranteeing Subsidiaries shall be jointly and severally obligated to pay the same immediately. This is a guarantee of
payment and not a guarantee of collection. 
 (b)        The obligations hereunder
shall be unconditional (to the extent legally permitted under such Guaranteeing Subsidiary’s jurisdiction of organization), 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 Issuers, 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 following is hereby waived: diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a
proceeding first against the Issuers, protest, notice and all demands whatsoever. 
 (d)        The Guarantees shall not be discharged except by complete performance of the obligations contained in the Notes, the Indenture and this Supplemental Indenture, and each Guaranteeing
Subsidiary accepts all obligations of a Guarantor under the Indenture. 
 (e)        If any Holder or the Trustee is required by any court or otherwise to return to the Issuers, the Guarantors (including the Guaranteeing Subsidiaries), or any custodian, trustee, liquidator
or other similar official acting in relation to either the Issuers or the Guarantors, any amount paid either to the Trustee or such Holder, these Guarantees, to the extent theretofore discharged, shall be reinstated in full force and effect.

 (f)        No Guaranteeing Subsidiary shall 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. 
 (g)        As between the Guaranteeing Subsidiaries, 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 6 of the Indenture for the purposes of these Guarantees, 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 6 of the Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guaranteeing Subsidiaries for the
purpose of the Guarantees.

 (h)        Each 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 Guarantees. 
 (i)        Pursuant to Section 10.02 of the Indenture, after giving effect to all other
contingent and fixed liabilities that are relevant under any applicable Bankruptcy Law or fraudulent conveyance 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 10 of the Indenture, the new Guarantees shall be limited to the maximum amount permissible such that the obligations of such Guaranteeing Subsidiary under the Guarantees
will not constitute a fraudulent transfer or conveyance or otherwise violate applicable law as set forth in Article 10 of the Indenture. 
 (j)        The Guarantees shall remain in full force and effect and continue to be effective should any petition be filed by or against the Issuers for liquidation,
reorganization, should the Issuers become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Issuers’ assets, and shall, to the fullest extent
permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any
obligee on the Notes and Guarantees, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof, is
rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. 
 (k)        In case any provision of the Guarantees shall be invalid, illegal or unenforceable,
the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 (l)        The Guarantees shall be a general unsecured senior obligation of each Guaranteeing Subsidiary, ranking pari passu with any other future Senior Indebtedness of each Guaranteeing
Subsidiary, if any. 
 (m)        Each payment to be made by each Guaranteeing
Subsidiary in respect of the Guarantees shall be made without set-off, counterclaim, reduction or diminution of any kind or nature. 
 (3)        Execution and Delivery. Each Guaranteeing Subsidiary agrees that these Guarantees shall remain in full force and effect notwithstanding the absence of the endorsement of any notation
of such Guarantees on the Notes.
