                        acceleration of such obligations as provided in Article
                        6 of the First Supplemental Indenture, such obligations
                        (whether or not due and payable) shall forthwith become

                        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 First Supplemental
                        Indenture, after giving effect to any maximum amount and

                        relevant under any applicable Bankruptcy or fraudulent
                        conveyance laws, and after giving effect to any
                        collections from, rights to receive contribution from or

                        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 First Supplemental

<PAGE>

                              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

                        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 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 First
                        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.

                        the assets of any Subsidiary Guarantor, by way of
                        merger, consolidation or otherwise, or a sale or other
                        disposition of all to the capital stock of any
                        Subsidiary Guarantor, then such Subsidiary 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 Subsidiary 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 Subsidiary Guarantor) will be

                        released and relieved of any obligations under its
                        Subsidiary 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 Officer's 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 First Supplemental Indenture, the Trustee shall
                        execute any documents reasonably required in order to
                        evidence the release of any Subsidiary Guarantor from
                        its 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 First 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.
