 W I T N
E S S E T H 
 WHEREAS, each of the Company 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 March 26, 2007, providing for the issuance of an unlimited aggregate principal amount of 9.750% Senior Subordinated Notes due 2017 (the “Senior
Subordinated 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 unconditionally guarantee all of the Company’s Obligations under the Senior Subordinated 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 Senior Subordinated 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. The Guaranteeing Subsidiary hereby agrees as follows: 
 (a) Along with all Guarantors named in the Indenture, to jointly and severally unconditionally guarantee to each Holder of a Senior Subordinated 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 Senior Subordinated Notes or the obligations of the Company hereunder or thereunder,
that: 
 (i) the principal of and interest, premium and Special Interest, if any, on the Senior Subordinated 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 Senior Subordinated Notes, if any, if lawful, and all other obligations of the Company 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 







 (ii) in case of any extension of time of payment or renewal of any Senior Subordinated 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 Subsidiary 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, irrespective of the validity, regularity or enforceability of the Senior
Subordinated Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Senior Subordinated 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 following is hereby waived: 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. 
 (d) This Guarantee shall not be discharged except by complete performance of the
obligations contained in the Senior Subordinated Notes, the Indenture and this Supplemental Indenture, and the 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 Company, the Guarantors (including the Guaranteeing Subsidiary),
or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid either to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. 
 (f) The Guaranteeing Subsidiary 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. 
 (g) As between the
Guaranteeing Subsidiary, 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 this 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 6 of the
Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guaranteeing Subsidiary for the purpose of this Guarantee. 
 (h) 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 this Guarantee. 








 (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 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, this new Guarantee shall be limited to the maximum amount permissible such that the obligations of such Guaranteeing Subsidiary under this Guarantee will not
constitute a fraudulent transfer or conveyance. 
 (j) This Guarantee shall remain in full force and effect and continue to be effective
should any petition be filed by or against the Company for liquidation, reorganization, should the Company 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 Company’s 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 Senior Subordinated Notes are, pursuant to applicable
law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Senior Subordinated Notes and Guarantee, 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 Senior Subordinated Note 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 this Guarantee 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 obligations of the Guaranteeing Subsidiary under this Guarantee are subordinated in right of payment, to the extent and in the manner provided in Article 13 of the Indenture, to the prior payment in full of
all existing and future Senior Indebtedness of the Guaranteeing Subsidiary. 
 (m) Each payment to be made by the Guaranteeing Subsidiary in
respect of this Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature. 
 (3) Execution and
Delivery. The Guaranteeing Subsidiary agrees that the Guarantee shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Senior Subordinated Notes. 
 (4) Merger, Consolidation or Sale of All or Substantially All Assets. 
 (a) Except as otherwise provided in Section 5.01(c) of the Indenture, the Guaranteeing Subsidiary may not consolidate or merge with or into or wind
up into (whether or not the Issuer or Guaranteeing Subsidiary is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions,
to any Person unless: 







 (i) (A) the Guaranteeing Subsidiary is the surviving corporation or the Person formed by or surviving any
such consolidation or merger (if other than the Guaranteeing Subsidiary) or to which such sale, assignment, transfer, lease, conveyance or other disposition will have been made is a corporation organized or existing under the laws of the
jurisdiction of organization of the Guaranteeing Subsidiary, as the case may be, or the laws of the United States, any state thereof, the District of Columbia, or any territory thereof (the Guaranteeing Subsidiary or such Person, as the case may be,
being herein called the “Successor Entity”); 
 (B) the Successor Entity, if other than the Guaranteeing Subsidiary,
expressly assumes all the obligations of the Guaranteeing Subsidiary under the Indenture and the Guaranteeing Subsidiary’s related Guarantee pursuant to supplemental indentures or other documents or instruments in form reasonably satisfactory
to the Trustee; 
 (C) immediately after such transaction, no Default exists; and 
 (D) the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger
or transfer and such supplemental indentures, if any, comply with the Indenture; or 
 (ii) the transaction is made in compliance with
Section 4.10 of the Indenture; 
 (b) Subject to certain limitations described in the Indenture, the Successor Entity will succeed to,
and be substituted for, the Guaranteeing Subsidiary under the Indenture and the Guaranteeing Subsidiary’s Guarantee. Notwithstanding the foregoing, the Guaranteeing Subsidiary may merge into or transfer all or part of its properties and assets
to another Guarantor or the Company. 
 (5) Releases. The Guarantee of the Guaranteeing Subsidiary shall be automatically and
unconditionally released and discharged, and no further action by the Guaranteeing Subsidiary, the Company or the Trustee is required for the release of the Guaranteeing Subsidiary’s Guarantee, upon: 
 (1) (A) any sale, exchange or transfer (by merger or otherwise) of the Capital Stock of the Guaranteeing Subsidiary (including any sale, exchange or
transfer), after which the Guaranteeing Subsidiary is no longer a Restricted Subsidiary or all or substantially all the assets of the Guaranteeing Subsidiary which sale, exchange or transfer is made in compliance with the applicable provisions of
the Indenture; 
 (B) the release or discharge of the guarantee by the Guaranteeing Subsidiary of the Senior Credit Facilities or the
guarantee which resulted in the creation of the Guarantee, except a discharge or release by or as a result of payment under such guarantee; 
 (C) the proper designation of the Guaranteeing Subsidiary as an Unrestricted Subsidiary; or 
 (D) the Company exercising its Legal
Defeasance option or Covenant Defeasance option in accordance with Article 8 of the Indenture or the Company’s obligations under the Indenture being discharged in accordance with the terms of the Indenture; and 







 (2) the Guaranteeing Subsidiary delivering to the Trustee an Officer’s Certificate and an Opinion of
Counsel, each stating that all conditions precedent provided for in the Indenture relating to such transaction have been complied with. 
 (6) No Recourse Against Others. No director, officer, employee, incorporator or stockholder of the Guaranteeing Subsidiary shall have any liability for any obligations of the Company or the Guarantors (including the Guaranteeing
Subsidiary) under the Senior Subordinated Notes, any Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting Senior Subordinated
Notes waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Senior Subordinated Notes.

 (8) Counterparts. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

 (10) The Trustee. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this
Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiary. 
 (11) Subrogation. The Guaranteeing Subsidiary shall be subrogated to all rights of Holders of Senior Subordinated Notes against the Company in respect of any amounts paid by the Guaranteeing Subsidiary pursuant to the provisions of
Section 2 hereof and Section 10.01 of the Indenture; provided that, if an Event of Default has occurred and is continuing, the Guaranteeing Subsidiary shall not be entitled to enforce or receive any payments arising out of, or based upon,
such right of subrogation until all amounts then due and payable by the Company under the Indenture or the Senior Subordinated Notes shall have been paid in full. 
 (12) Benefits Acknowledged. The Guaranteeing Subsidiary’s Guarantee is subject to the terms and conditions set forth in the Indenture. The Guaranteeing Subsidiary acknowledges that it will receive direct
and indirect benefits from the financing arrangements contemplated by the Indenture and this Supplemental Indenture and that the guarantee and waivers made by it pursuant to this Guarantee are knowingly made in contemplation of such benefits.

 (13) Successors. All agreements of the Guaranteeing Subsidiary in this Supplemental Indenture shall bind its Successors, except as
otherwise provided in Section 2(k) hereof or elsewhere in this Supplemental Indenture. All agreements of the Trustee in this Supplemental Indenture shall bind its successors.
