     Section 1.4.  Guarantees.  (a) Subject to the provisions of this Article 4,
                   ----------
each Guarantor, jointly and severally, hereby irrevocably and unconditionally
guarantees to each Holder of Securities and to the Trustee on behalf of the
Holders (i) the due and punctual payment of principal of, premium, if any, and
interest in full on each Security when and as the same shall become due and
payable whether at Stated Maturity, by declaration of acceleration or otherwise,
(ii) the due and punctual payment of interest on the overdue principal of,
premium, if any, and interest in full on the Securities, to the extent permitted
by law, and (iii) the due and punctual performance of all other Obligations of
the Company and the other Guarantors to the Holders or the Trustee, including
without limitation the payment of fees, expenses, indemnification or other
amounts, all in accordance with the terms of the Securities and the Indenture.
In case of the failure of the Company punctually to make any such principal or
interest payment or the failure of the Company or any other Guarantor to perform
any such other Obligation, each Guarantor hereby agrees to cause any such
payment to be made punctually when and as the same shall become due and payable,
whether at Stated Maturity, by declaration of acceleration or otherwise, and as
if such payment were made by the Company and to perform any such other
Obligation of the Company immediately.  Each Guarantor hereby further agrees to
pay any and all expenses (including reasonable counsel fees and expenses)
incurred by the Trustee or the Holders in enforcing any rights under these
Guarantees.  The Guarantees under this Article 4 are guarantees of payment and
not of collection.

     (b)  To the extent permitted by law, each of the Company and the Guarantors
hereby waives diligence, presentment, demand of payment, filing of claims with a
court in the event of merger, insolvency or bankruptcy of the Company or any
other Guarantor, any right to require a proceeding first against the Company or
any other Guarantor, protest or notice with respect to the Securities or the
indebtedness evidenced thereby and all demands whatsoever, and covenants that
these Guarantees will not be discharged except by complete performance of the
Obligations contained in the Securities and in the Indenture, or as otherwise
specifically provided therein and herein.

     (c)  To the extent permitted by law, each Guarantor hereby waives and
relinquishes:

     (i)  any right to require the Trustee, the Holders or the Company (each, a
          "Benefited Party") to proceed against the Company, the Subsidiaries of
          the Company or any other Person or to proceed against or exhaust any


           security held by a Benefited Party at any time or to pursue any other
           remedy in any secured party's power before proceeding against the
           Guarantors;

     (ii)  any defense that may arise by reason of the incapacity, lack of
           authority, death or disability of any other Person or Persons or the
           failure of a Benefited Party to file or enforce a claim against the
           estate (in administration, bankruptcy or any other proceeding) of any
           other Person or Persons;

     (iii) demand, protest and notice of any kind (except as expressly required
           by the Indenture), including but not limited to notice of the
           existence, creation or incurring of any new or additional
           indebtedness or obligation or of any action or non-action on the part
           of the Guarantors, the Company, the Subsidiaries of the Company, any
           Benefited Party, any creditor of the Guarantors, the Company or the
           Subsidiaries of the Company or on the part of any other Person
           whomsoever in connection with any obligations the performance of
           which are hereby guaranteed;

     (iv)  any defense based upon an election of remedies by a Benefited Party,
           including but not limited to an election to proceed against the
           Guarantors for reimbursement;

     (v)   any defense based upon any statute or rule of law which provides that
           the obligation of a surety must be neither larger in amount nor in
           other respects more burdensome than that of the principal;

     (vi)  any defense arising because of a Benefited Party's election, in any
           proceeding instituted under the Bankruptcy Law, of the application of
           Section 1111(b) (2) of the Bankruptcy Law; and

     (vii) any defense based on any borrowing or grant of a security interest
           under Section 364 of the Bankruptcy Law.

     (d)   Each Guarantor further agrees that, as between such Guarantor, on the
           one hand, and Holders and the Trustee, on the other hand, (i) for
           purposes of the relevant Guarantee, the maturity of the Obligations
           Guaranteed by such Guarantee may be accelerated as provided in
           Article 5 of the Indenture, notwithstanding any stay, injunction or
           other prohibition preventing such acceleration in respect of the
           Obligations guaranteed thereby, and (ii) in the event of any
           acceleration of such Obligations (whether or not due and payable)
           such Obligations shall forthwith become due and payable by such
           Guarantor for purposes of such Guarantee.

     (e)   The Guarantee shall continue to be effective or shall be reinstated,
           as the case may be, if at any time any payment, or any part thereof,
           of principal


          of, premium, if any, or interest on any of the Securities is rescinded
          or must otherwise be returned by the Holders or the Trustee upon the
          insolvency, bankruptcy or reorganization of the Company or any of the
          Guarantors, all as though such payment had not been made.

     (f)  Each Guarantor shall be subrogated to all rights of the Holders
          against the Company in respect of any amounts paid by such Guarantor
          pursuant to the provisions of the Guarantees or the Indenture;
          provided, however, that a Guarantor shall not be entitled to enforce
          --------  -------
          or to receive any payments until the principal of, premium, if any,
          and interest on all Securities issued hereunder shall have been paid
          in full.

     Section 4.2.  Obligations of Guarantors Unconditional.  Each Guarantor
                   ---------------------------------------
hereby agrees that its Obligations hereunder shall be Guarantees of payment and
shall be unconditional, irrespective of and unaffected by the validity,
regularity or enforceability of the Securities of the Indenture, or of any
amendment thereto or hereto, the absence of any action to enforce the same, the
waiver or consent by any Holder or by the Trustee with respect to any provisions
thereof or of the Indenture, the entry of any judgment against the Company or
any other Guarantor or any action to enforce the same or any other circumstance
which might otherwise constitute a legal or equitable discharge or defense of a
guarantor.

     Section 4.3.  Limitation on Guarantors' Liability.  Each Guarantor, and by
                   -----------------------------------
its acceptance hereof each holder, hereby confirms that it is the intention of
all such parties that the Guarantee by such Guarantor pursuant to its Guarantee
not constitute a fraudulent transfer or conveyance for purposes of the
Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent
Transfer Act or any similar federal or state law.  To effectuate the foregoing
intention, the Holders and such Guarantor hereby irrevocably agree that the
Obligations of such Guarantor under this Article 4 shall be limited to the
maximum amount as will, after giving effect to all other contingent and fixed
liabilities of such Guarantor and after giving effect to any collections from or
payments made by or on behalf of any other Guarantor in respect of the
Obligations of such other Guarantor under this Article 4, result in the
Obligation of such Guarantor under its Guarantee not constituting a fraudulent
transfer or conveyance under applicable federal or state law.

     Section 4.4.  Releases of Guarantees.  (a) If the Securities are defeased
                   ----------------------
in accordance with the terms of Article 13 of the Indenture, then each Guarantor
shall be deemed to have been released from and discharged of its obligations
under its Guarantee as provided in Article 13 of the Indenture, applied mutaris
mutandis, subject to the conditions state therein.

     (b)  In the event an entity that is a Guarantor ceases to be a guarantor
     under the Senior Credit Agreement (or any other credit agreement renewing,
     refunding, replacing, restating, refinancing or extending the Senior Credit
     Agreement), such entity shall also cease to be a Guarantor, whether or not
     a Default or an Event of Default is then outstanding.


     (c)  Any Guarantor not released from its obligations under its Guarantee
     shall remain liable for the full amount of principal of, premium, if any,
     and interest on the Securities and for the other obligations of the
     Company, such Guarantor and any other Guarantor under the Indenture as
     provided in this Article 4.

     Section 4.5.  Application of Certain Terms and Provisions to Guarantors.
                   ---------------------------------------------------------
(a) Any notice or demand which by any provision of the Indenture is required or
permitted to be given or served by the Trustee or by the Holders of Securities
to or on any Guarantor may be given or served as described in Section 105 of the
Indenture.

          (b)  Upon any demand, request or application by any Guarantor to the
Trustee to take any action under the Indenture, such Guarantor shall furnish to
the Trustee such certificates and opinions as are required in Section 603 of the
Indenture as if all references therein to the Company were references to such
Guarantor.

     Section 4.6.  Additional Guarantors.  The Company shall cause each
                   ---------------------
subsidiary of the Company that becomes a guarantor under the Senior Credit
Agreement, as amended (or any other credit agreement renewing, refunding,
replacing, restating, refinancing or extending the Senior Credit Agreement),
after the date of this First Supplemental Indenture, to execute and deliver to
the Trustee, promptly upon any such formation or acquisition (a) a supplemental
indenture in form and substance satisfactory to the Trustee which subjects such
subsidiary to the provisions of the Indenture as a Guarantor, and (b) an Opinion
of Counsel to the effect that such supplemental indenture has been duly
authorized and executed by such subsidiary and constitutes the legal, valid,
binding and enforceable obligation of such subsidiary (subject to such customary
exceptions concerning fraudulent conveyance laws, creditors' rights and
equitable principles as may be acceptable to the Trustee in its discretion).


          IN WITNESS WHEREOF, the parties hereto have caused this First
Supplemental Indenture to be duly executed as of the day and year first above
written.
