 W I T N E S S E T H

 WHEREAS, each of the Issuer, Health Finance Corporation (the
“Co-Issuer” and, together with the Issuer, the “Issuers”) and the Guarantors (as defined in the Indenture and the First Supplemental Indenture referred to below) has heretofore executed and delivered to the Trustee
an indenture (the “Indenture”), dated as of November 23, 2005, and a First Supplemental Indenture (the “First Supplemental Indenture”), dated as of June 1, 2006, providing for the issuance of an unlimited
aggregate principal amount of 11 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 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 Second 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. The Guaranteeing Subsidiary hereby agrees as follows: 
 (a) Along with all Guarantors named in the Indenture and in the First Supplemental 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 
 (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 Subsidiary shall be jointly and severally obligated to pay
the same immediately. This is a guarantee of payment and not a guarantee of collection. 
  

 1 








 (b) The 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
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 either of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever. 
 (d) This Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, the Indenture, the First Supplemental Indenture and this Second 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 Issuers, the Guarantors (including the Guaranteeing Subsidiary), 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, 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 11.02 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 11 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 either of the Issuers for liquidation, reorganization, 

  

 2 








 
should either of 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 either 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 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 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) This Guarantee shall be a general unsecured senior subordinated obligation of such Guaranteeing Subsidiary, ranking pari passu with any other future Senior Indebtedness of the Guaranteeing Subsidiary, if
any. 
 (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 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, limited liability company or limited partnership 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
Person”); 
 (B) the Successor Person, 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 
  

 3 








 (D) the Issuer 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 Person 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 Issuer. 
 (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 Issuer 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 and any other guarantee which
resulted in (or would by itself require) 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 Issuers exercising their Legal Defeasance option or Covenant Defeasance option in accordance with Article 8 of the Indenture or the Issuers’ 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, representative, officer, employee, incorporator or stockholder of the Guaranteeing Subsidiary shall have any liability for any obligations of the Issuers or the Guarantors (including the
Guaranteeing Subsidiary) under the Notes, any Guarantees, the Indenture or this Second Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting Notes waives and
releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. 
 (7) Governing Law.
THIS SECOND SUPPLEMENTAL INDENTURE WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
