                               W I T N E S S E T H

                  WHEREAS, the Company and the Subsidiary Guarantors have
heretofore executed and delivered to the Trustee an Indenture dated as of
June 8, 1999 as supplemented by a First Supplemental Indenture, dated as of

                  WHEREAS, the Indenture provides that under certain
circumstances the Guaranteeing Subsidiaries shall execute and deliver to the

shall unconditionally guarantee all of the Company's Obligations under the Notes

                  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 parties hereto do hereby mutually covenant and agree 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. Each of 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, 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 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, and the Guaranteeing Subsidiary accepts all obligations
     of a Subsidiary Guarantor under 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 Indenture for the purposes of this Subsidiary Guarantee,
     notwithstanding any stay, injunction or other prohibition preventing such
     acceleration in respect of the obligations guaranteed hereby, and (y) in

                                       2



     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 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
     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
     Subsidiary Guarantor in respect of the obligations of such other Subsidiary
     Guarantor under Article 11 of the Indenture, this new Subsidiary Guarantee
     shall be limited to the maximum amount permissible such that the
     obligations of such Subsidiary Guarantor under this Subsidiary Guarantee
     will not constitute a fraudulent transfer or conveyance.

                  (j)      Pursuant to Section 11.02 of the Indenture, the
     obligations of each Subsidiary Guarantor under its Subsidiary Guarantee
     pursuant to Article II of the Indenture shall be junior and subordinated to
     the Senior Indebtedness of such Subsidiary Guarantor on the same basis as
     the Notes are junior and subordinated to the Senior Indebtedness of the
     Company.

                  3.       Execution and Delivery. Each Guaranteeing Subsidiary
     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 Sections 11.05 and 11.06 of the 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

                                       3


          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 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 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 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 a sale or other disposition of all of
     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, 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 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 4.15 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 4.15 of the 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 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 Subsidiary Guarantees, the Indenture or this Supplemental Indenture or
     for

                                       4


     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
     Subsidiaries and the Company.

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