Trustee 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

          2. Agreement to Guarantee. The Guaranteeing Subsidiaries hereby agrees as follows:




	 	(a)	 	Along with all Subsidiary Guarantors named in the Indenture, to jointly and
severally 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
Company hereunder or thereunder, that:






	 	(i)	 	the principal of and interest 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 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
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 Subsidiary Guarantors shall be jointly and severally
obligated to pay the same immediately.






	 	(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
Company, any action to enforce the same or any other circumstance which might
otherwise constitute a legal or equitable discharge or defense of a Subsidiary
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 Subsidiary Guarantee shall not be discharged except by complete
performance of the obligations contained in the Notes and the Indenture.
	 
	 	(e)	 	If any Holder or the Trustee is required by any court or otherwise to return
to the Company, the Subsidiary Guarantors, or any custodian, Trustee, liquidator or
other similar official acting in relation to either the Company or the Subsidiary
Guarantors, any amount paid by either to the Trustee or such Holder, this Subsidiary
Guarantee, to the extent theretofore discharged, shall be reinstated in full force and
effect.
	 
	 	(f)	 	The Guaranteeing Subsidiaries 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 Subsidiary 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 6 of the Tenth Supplemental Indenture for
the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or
other prohibition preventing such acceleration in respect of the




2









 






	 		 	obligations guaranteed hereby, and (y) in the event of any declaration of
acceleration of such obligations as provided in Article 6 of the Tenth Supplemental
Indenture, such obligations (whether or not due and payable) shall forthwith become
due and payable by the Subsidiary Guarantors for the purpose of this Subsidiary
Guarantee.
	 
	 	(h)	 	The Subsidiary Guarantors shall have the right to seek contribution from any
non-paying Subsidiary Guarantor so long as the exercise of such right does not impair
the rights of the Holders under the Subsidiary Guarantee.
	 
	 	(i)	 	Pursuant to Section 9.04 of the Tenth Supplemental Indenture, after giving
effect to any maximum amount and any 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 Subsidiary Guarantor in respect of the obligations
of such other Subsidiary Guarantor under Article 9 of the Tenth Supplemental Indenture
shall result in the obligations of such Subsidiary Guarantor under its Subsidiary
Guarantee not constituting a fraudulent transfer or conveyance.





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



          4. Guaranteeing Subsidiaries May Consolidate, Etc. on Certain Terms.




	 	(a)	 	The Guaranteeing Subsidiaries may not consolidate with or merge with or into
(whether or not such Subsidiary Guarantor is the surviving Person) another
corporation, Person or entity whether or not affiliated with such Subsidiary Guarantor
unless:






	 	(i)	 	subject to Section 9.04 of the Tenth Supplemental Indenture,
the Person formed by or surviving any such consolidation or merger (if other
than a Subsidiary Guarantor or the Company) unconditionally assumes all the
obligations of such Subsidiary Guarantor, pursuant to a supplemental Indenture
in form and substance reasonably satisfactory to the Trustee, under the Notes,
the Indenture and the Subsidiary Guarantee on the terms set forth herein or
therein; and
	 
	 	(ii)	 	immediately after giving effect to such transaction, no
Default or Event of Default exists.






	 	(b)	 	In case of any such consolidation, merger, sale or conveyance and upon the
assumption by the successor corporation, by supplemental Indenture, executed and
delivered to the Trustee and satisfactory in form to the Trustee, of the Subsidiary
Guarantee endorsed upon the Notes and the due and punctual performance of all of the
covenants and conditions of the Indenture to be performed by the Subsidiary Guarantor,
such successor corporation shall succeed to and be substituted for the Subsidiary
Guarantor with the same effect as if it had been named herein as a Subsidiary
Guarantor. Such successor corporation thereupon may cause to be signed any or all of
the Subsidiary Guarantees to be




3









 






	 	 	 	endorsed upon all of the Notes issuable hereunder which theretofore shall not have
been signed by the Company and delivered to the Trustee. All the Subsidiary
Guarantees so issued shall in all respects have the same legal rank and benefit
under the Indenture as the Subsidiary Guarantees theretofore and thereafter issued
in accordance with the terms of the Indenture as though all of such Subsidiary
Guarantees had been issued at the date of the execution hereof.
	 
	 	(c)	 	Except as set forth in Articles 4 and 5 of the Tenth Supplemental Indenture,
and notwithstanding clauses (a) and (b) above, nothing contained in the Indenture or
in any of the Notes shall prevent any consolidation or merger of a Subsidiary
Guarantor with or into the Company or another Subsidiary Guarantor, or shall prevent
any sale or conveyance of the property of a Subsidiary Guarantor as an entirety or
substantially as an entirety to the Company or another Subsidiary Guarantor.





          5. Releases.




	 	(a)	 	In the event of (i) the release or discharge of the Guarantee of the Credit
Agreement by a Subsidiary Guarantor, except a discharge or release by or as a result
of payment under such Guarantee or (ii) a sale or other disposition by way of such a
merger, consolidation or otherwise, of all of the capital stock of any Subsidiary
Guarantor, then such Subsidiary Guarantor (in the event of a sale or other disposition
of all of the capital stock of such Subsidiary Guarantor) will be released and
relieved of any obligations under its Subsidiary Guarantee.
	 
	 	(b)	 	Any Subsidiary Guarantor not released from its obligations under its
Subsidiary Guarantee shall remain liable for the full amount of principal of and
interest on the Notes and for the other obligations of any Subsidiary Guarantor under
the Indenture as provided in Article 9 of the Tenth Supplemental Indenture.





          6. No Recourse Against Others. No past, present or future director, officer, employee,
incorporator, stockholder or agent of the Guaranteeing Subsidiaries, as such, shall have any
liability for any obligations of the Company or any Guaranteeing Subsidiaries under the Notes, any
Subsidiary 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 of the Notes by
accepting a Note waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities
under the federal securities laws and it is the view of the Commission that such a waiver is
against public policy.



          7. NEW YORK LAW TO GOVERN. THE LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO
CONSTRUE THIS SUPPLEMENTAL INDENTURE.



          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.



          9. Effect of Headings. The Section headings herein are for convenience only and shall not
affect the construction hereof.

          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 Subsidiaries
and the Company.
