                  3. 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 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
<PAGE>   3

                  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
                  Guarantee.

                  (i) Pursuant to Section 11.02 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, 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.

                  4. 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.

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

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

                           (i)      subject to Sections 11.04 and 11.05 of the
                                    Indenture, the Person formed by or surviving
                                    any such consolidation or merger (if other
                                    than a Guarantor or the Company)
                                    unconditionally assumes all the obligations
                                    of such Guarantor, pursuant to a
                                    supplemental indenture in form and substance
                                    reasonably satisfactory to the
<PAGE>   4
                                    Trustee, under the Notes, the Indenture and
                                    the Note 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
                  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
                  corporation 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 corporation thereupon may cause
                  to be signed any or all of the Note 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 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 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, 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
<PAGE>   5
                  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.
