         SECOND SUPPLEMENTAL INDENTURE (this "Supplemental Indenture"), dated as

the Company, the other Guarantors (as defined in the Indenture referred to
herein) and The Bank of New York, as trustee under the Indenture referred to
below (the "Trustee").

                               W I T N E S S E T H

         WHEREAS, the Company has heretofore executed and delivered to the
Trustee an Indenture (the "Indenture"), dated as of June 6, 2002 pursuant to
which $437,773,000 aggregrate principal amount of 9 7/8% Senior Subordinated
Notes due 2012 (the "Notes") were issued;

         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 Notes and the Indenture on
the terms and conditions set forth herein (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
Guaranteeing Subsidiary and the 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 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 Guarantee to each Holder of a Note authenticated
         and delivered by the Trustee and to the Trustee and its successors and
         assigns, the Notes or the obligations of the Company hereunder or
         thereunder, that:

                  (i)   the principal of, and premium and Liquidated Damages,
                  if any, 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 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 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 Note Guarantee shall not be discharged except by
         complete performance of the obligations contained in the Notes and the
         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, or any custodian,
         trustee, liquidator or other similar official acting in relation to
         either the Company or the Guarantors, any amount paid by either to the
         Trustee or such Holder, this Note 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 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 Indenture for the purposes of this 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 6 of the Indenture, such obligations (whether or
         not due and payable) shall forthwith become due and payable by the
         Guarantors for the purpose of this Note Guarantee.




                  (h) The Guarantors 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.

                  (i) Pursuant to Section 10.02 of the Indenture, after giving
         effect to any maximum amount and 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 Note
         Guarantee shall be limited to the maximum amount permissible such that
         the obligations of such Guarantor under this Note Guarantee will not
         constitute a fraudulent transfer or conveyance.

         3.       EXECUTION AND DELIVERY.  Each Guaranteeing Subsidiary agrees
that the Note Guarantees shall remain in full force and effect notwithstanding
any failure to endorse on each Note a notation of such Note Guarantee.

         4.       GUARANTEEING SUBSIDIARY MAY CONSOLIDATE, ETC. ON CERTAIN
                  TERMS.

                  (a) The Guaranteeing Subsidiary may not sell or otherwise
         dispose of all substantially all of its assets to, or consolidate with
         or merge with or into (whether or not such Guarantor is the surviving
         Person) another Person, other than the Company or another Guarantor
         unless:

         (i)      immediately after giving effect to such transaction, no
         Default or Event of Default exists; and

         (ii)     either (A) subject to Sections 11.04 and 11.05 of the
         Indenture, the Person acquiring the property in any such sale or
         disposition or the Person formed by or surviving any such consolidation
         or merger unconditionally assumes all the obligations of that
         Guarantor, pursuant to a supplemental indenture in form and substance
         reasonably satisfactory to the Trustee, under the Notes, the Indenture
         and the Note Guarantee on the terms set forth herein or therein; or (B)
         the Net Proceeds of such sale or other disposition are applied in
         accordance with the applicable provisions of the Indenture, including
         without limitation, Section 4.10 thereof.

                  (b) In case of any such consolidation, merger, sale or
         conveyance and upon the assumption by the successor Person, by
         supplemental indenture, executed and delivered to the Trustee and
         satisfactory in form to the Trustee, of the Note 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
         Guarantor, such successor Person shall succeed to and be substituted
         for the Guarantor with the same effect as if it had been named herein
         as a Guarantor. Such successor Person thereupon may cause to be signed
         any or all of the Note Guarantees to be endorsed upon all of the Notes
         issuable under the Indenture which theretofore shall not have been
         signed by the Company and delivered to the Trustee. All the Note
         Guarantees so issued shall in all respects have the same legal rank and
         benefit under the





         Indenture as the Note Guarantees theretofore and thereafter issued in
         accordance with the terms of the Indenture as though all of such Note
         Guarantees had been issued at the date of the execution hereof.

                  (c) Except as set forth in Articles 4 and 5 and Section 11.05
         of Article 11 of the 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 Guarantor with or into the
         Company or another Guarantor, or shall prevent any sale or conveyance
         of the property of a Guarantor as an entirety or substantially as an
         entirety to the Company or another Guarantor.

         5.       RELEASES.

                  (a) In the event of any sale or other disposition of all or
         substantially all of the assets of any Guarantor, by way of merger,
         consolidation or otherwise, or a sale or other disposition of all of
         the capital stock of any Guarantor, in each case to a Person that is
         not (either before or after giving effect to such transaction) a
         Restricted Subsidiary of the Company, then such Guarantor (in the event
         of a sale or other disposition, by way of merger, consolidation or
         otherwise, of all of the capital stock of such Guarantor) or the
         corporation acquiring the property (in the event of a sale or other
         disposition of all or substantially all of the assets of such
         Guarantor) will be released and relieved of any obligations under its
         Note Guarantee; provided that the Net Proceeds of such sale or other
         disposition are applied in accordance with the applicable provisions of
         the Indenture, including without limitation Section 4.10 of the
         Indenture. Upon delivery by the Company to the Trustee of an Officers'
         Certificate and an Opinion of Counsel to the effect that such sale or
         other disposition was made by the Company in accordance with the
         provisions of the Indenture, including without limitation Section 4.10
         of the Indenture, the Trustee shall execute any documents reasonably
         required in order to evidence the release of any Guarantor from its
         obligations under its Note Guarantee.

         (b) Any Guarantor not released from its obligations under its Note
Guarantee shall remain liable for the full amount of principal of and interest
on the Notes and for the other obligations of any Guarantor under the Indenture
as provided in Article 11 of the Indenture.

         6. NO RECOURSE AGAINST OTHERS. No past, present or future director,
officer, employee, incorporator, stockholder or agent of the Guaranteeing
Subsidiary, as such, shall have any liability for any obligations of the Company
or any Guaranteeing Subsidiary under the Notes, any Note 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 SEC that such a waiver is against public policy.

         7. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK
SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT WITHOUT
GIVING EFFECT TO APPLICABLE PRINCIPLES OF






CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER
JURISDICTION WOULD BE REQUIRED THEREBY.

         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 Subsidiary and the
Company.










         IN WITNESS WHEREOF, the parties hereto have caused this Supplemental
Indenture to be duly executed and attested, all as of the date first above
written.
