      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
      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 Guarantee.

            (i) Pursuant to Section 11.03 of the 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 Guarantor
      in respect of the obligations of such other Guarantor under Article 11 of
      the Indenture, the obligations of each Guaranteeing Subsidiary shall be
      limited to the maximum amount as will result in the obligations of such
      Guarantor under its Guarantee not constituting a fraudulent transfer or
      conveyance.

      3. SUBORDINATION. The obligations of each Guaranteeing Subsidiary under
its guarantee pursuant to this Supplemental Indenture shall be junior and
subordinated to the Senior Debt of each such Guaranteeing Subsidiary on the same
basis as the Notes are junior and subordinated to the Senior Debt of the
Company. For the purposes of the foregoing sentence, the Trustee and the Holders
shall have the right to receive and/or retain payments by each Guaranteeing
Subsidiary only at such time as they may receive and/or retain payments in
respect of the notes pursuant to the indenture, including Article 10 thereof.

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

      5. GUARANTEEING SUBSIDIARY MAY CONSOLIDATE, ETC. ON CERTAIN TERMS. Each
Guaranteeing Subsidiary will be subject to Section 11.05 of the Indenture.

      6. RELEASES.

            (a) In the event of a sale or other disposition of all of the assets
      of any Guarantor, by way of merger, consolidation or otherwise, or a sale
      or other disposition of all to the capital stock of any Guarantor, 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

                                       3
<PAGE>

      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 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 Guarantee.

            (b) Any Guarantor not released from its obligations under its
      Guarantee shall remain liable for the full amount of principal of and
      interest on the and for the other obligations of any guarantor under the
      indenture as provided in Article 10 of the indenture.

      7. NO RECOURSE AGAINST OTHERS. No past, present or future director,
officer, employee, incorporator, stockholder or agent of either Guaranteeing
Subsidiary, as such, shall have any liability for any obligations of the Company
or any Guaranteeing Subsidiary under the 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 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.

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

      9. 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. EFFECT OF HEADINGS. The Section headings herein are for convenience
only and shall not affect the construction hereof.

      11. 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.

                                       4

      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.
