as follows:


<PAGE>

          (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,  irrespective of the validity and  enforceability of
               the  Indenture,  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  Subsidiary  Guarantee  shall  not be  discharged  except by
               complete  performance of the  obligations  contained in the Notes
               and 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  Subsidiary
               Guarantee,  to  the  extent  theretofore  discharged,   shall  be
               reinstated in full force and effect.


                                     - 2 -

          (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  Subsidiary
               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 Subsidiary 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  Subsidiary
               Guarantee.

          (i)  Notwithstanding the foregoing,  in the event that this Subsidiary
               Guarantee  would  constitute  or  result  in a  violation  of any
               applicable  fraudulent  conveyance or similar law of any relevant
               jurisdiction,  the  liability of the  Guarantor  under this Sixth
               Supplemental  Indenture  and its  Subsidiary  Guarantee  shall be
               reduced to the maximum amount  permissible  under such fraudulent
               conveyance or similar law.

          3.   SUBORDINATION.   Payment  of  principal,  premium,  if  any,  and
interest  and  Liquidated  Damages,  if  any,  on the  Subsidiary  Guarantee  is
subordinated  to the prior payment in full of Senior Debt on the terms  provided
in the Indenture.

          4.   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.

          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 Section 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





                                     - 3 -

<PAGE>

                    the   obligations   of  such   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 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  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 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  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.

     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 of 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  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  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





                                     - 4 -

<PAGE>

          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
          Subsidiary Guarantee.

     (b)  Any 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 Guarantor
          under the Indenture as provided in Article 11 of the Indenture.

     7.   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 Sixth  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.

     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  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.

     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 Subsidiary and the Company.
