                               GUARANTY PROVISIONS

     SECTION 2.1. Guaranty. Each Guarantor hereby absolutely, unconditionally
and irrevocably

          (a) guarantees the full and punctual payment when due, whether at
     stated maturity, by required prepayment, declaration, acceleration, demand
     or otherwise, of all Obligations of the Borrower and each other Obligor now
     or hereafter existing, whether for principal, interest, fees, expenses or
     otherwise (including all such amounts which would become due but for the
     operation of the automatic stay under Section 362(a) of the United States
     Bankruptcy Code, 11 U.S.C. ss.362(a), and the operation of Sections 502(b)
     and 506(b) of the United States Bankruptcy Code, 11 U.S.C. ss.502(b) and
     ss.506(b)), and

          (b) indemnifies and holds harmless each Secured Party and each holder
     of a Note for any and all reasonable costs and expenses (including
     reasonable attorney's fees and


                                        2

<PAGE>   3

     expenses) incurred by such Secured Party or such holder, as the case may
     be, in enforcing any rights under this Guaranty;

provided, however, that each Guarantor shall be liable under this Guaranty for
the maximum amount of such liability that can be hereby incurred without
rendering this Guaranty, as it relates to each Guarantor, voidable under
applicable law relating to fraudulent conveyance or fraudulent transfer, and not
for any greater amount. This Guaranty constitutes a guaranty of payment when due
and not of collection, and each Guarantor specifically agrees that it shall not
be necessary or required that any Secured Party or any holder of any Note
exercise any right, assert any claim or demand or enforce any remedy whatsoever
against the Borrower or any other Obligor (or any other Person) before or as a
condition to the obligations of each Guarantor hereunder.

     SECTION 2.2. Acceleration of Guaranty. Each Guarantor agrees that, in the
event of any Event Default described in Section 8.1.9 of the Credit Agreement
and if such event shall occur at a time when any of the Obligations of the
Borrower and each other Obligor may not then be due and payable, each Guarantor
jointly and severally agrees that it will pay to the Lenders forthwith the full
amount which would be payable hereunder by such Guarantor if all such
Obligations were then due and payable.

     SECTION 2.3. Guaranty Absolute, etc. This Guaranty shall in all respects be
a continuing, absolute, unconditional and irrevocable guaranty of payment, and
shall remain in full force and effect until all Obligations of the Borrower and
each other Obligor (including each Guarantor) have been paid in full in
immediately available funds, all obligations of each Guarantor hereunder shall
have been paid in full in cash, all Letters of Credit have been terminated or
expired and all Commitments shall have terminated. The liability of each
Guarantor under this Guaranty shall be absolute, unconditional and irrevocable
irrespective of:

          (a) any lack of validity, legality or enforceability of the Credit
     Agreement, any Note or any other Loan Document;

          (b) the failure of any Secured Party or any holder of any Note

               (i) to assert any claim or demand or to enforce any right or
          remedy against the Borrower, any other Obligor or any other Person
          (including any other guarantor (including any Guarantor)) under the
          provisions of the Credit Agreement, any Note, any other Loan Document
          or otherwise, or

               (ii) to exercise any right or remedy against any other guarantor
          (including any Guarantor) of, or collateral securing, any Obligations
          of the Borrower or any other Obligor;

          (c) any change in the time, manner or place of payment of, or in any
     other term of, all or any of the Obligations of the Borrower or any other
     Obligor, or any other


                                        3

<PAGE>   4

extension, compromise or renewal of any Obligation of the Borrower or any other
Obligor;

          (d) any reduction, limitation, impairment or termination of any
     Obligations of the Borrower or any other Obligor for any reason, including
     any claim of waiver, release, surrender, alteration or compromise, and
     shall not be subject to (and each Guarantor hereby waives any right to or
     claim of) any defense or setoff, counterclaim, recoupment or termination
     whatsoever by reason of the invalidity, illegality, nongenuineness,
     irregularity, compromise, unenforceability of, or any other event or
     occurrence affecting, any Obligations of the Borrower, any other Obligor or
     otherwise;

          (e) any amendment to, rescission, waiver, or other modification of, or
     any consent to departure from, any of the terms of the Credit Agreement,
     any Note or any other Loan Document;

          (f) any addition, exchange, release, surrender or non-perfection of
     any collateral, or any amendment to or waiver or release or addition of, or
     consent to departure from, any other guaranty, held by any Secured Party or
     any holder of any Note securing any of the Obligations of the Borrower or
     any other Obligor; or

          (g) any other circumstance which might otherwise constitute a defense
     available to, or a legal or equitable discharge of, the Borrower, any other
     Obligor, any surety or any guarantor.

     SECTION 2.4. Reinstatement, etc. Each Guarantor agrees that this Guaranty
shall continue to be effective or be reinstated, as the case may be, if at any
time any payment (in whole or in part) of any of the Obligations is rescinded or
must otherwise be restored by any Secured Party or any holder of any Note, upon
the insolvency, bankruptcy or reorganization of the Borrower, any other Obligor
or otherwise, all as though such payment had not been made.

     SECTION 2.5. Waiver, etc. Each Guarantor hereby waives promptness,
diligence, notice of acceptance and any other notice with respect to any of the
Obligations of the Borrower or any other Obligor and this Guaranty and any
requirement that the Administrative Agent, any other Secured Party or any holder
of any Note protect, secure, perfect or insure any security interest or Lien, or
any property subject thereto, or exhaust any right or take any action against
the Borrower, any other Obligor or any other Person (including any other
guarantor) or entity or any collateral securing the Obligations of the Borrower
or any other Obligor, as the case may be.

     SECTION 2.6. Postponement of Subrogation, etc. Each Guarantor agrees that
it will not exercise any rights which it may acquire by way of rights of
subrogation under this Guaranty, by any payment made hereunder or otherwise,
until the prior payment in full in immediately available funds of all
Obligations of the Borrower and each other Obligor, the termination or
expiration of all Letters of Credit and the termination of all Commitments. Any
amount paid to


                                        4

<PAGE>   5

such Guarantor on account of any such subrogation rights prior to the payment in
full in immediately available funds of all Obligations of the Borrower and each
other Obligor shall be held in trust for the benefit of the Secured Parties and
each holder of a Note and shall immediately be paid to the Administrative Agent
for the benefit of the Secured Parties and each holder of a Note and applied
against the Obligations, whether matured or unmatured, in accordance with the
terms of the Credit Agreement; provided, however, that if

          (a) each Guarantor has made payment to the Secured Parties and each
     holder of a Note of all or any part of the Obligations of the Borrower or
     any other Obligor, and

          (b) all Obligations of the Borrower and each other Obligor have been
     paid in full in immediately available funds, all Letters of Credit have
     been terminated or expired and all Commitments have been permanently
     terminated,

each Secured Party and each holder of a Note agrees that, at each Guarantor's
request, the Administrative Agent, on behalf of the Secured Parties and the
holders of the Notes, will execute and deliver to each Guarantor appropriate
documents (without recourse and without representation or warranty) necessary to
evidence the transfer by subrogation to each Guarantor of an interest in the
Obligations of the Borrower and each other Obligor resulting from such payment
by each Guarantor. In furtherance of the foregoing, for so long as any
Obligations or Commitments remain outstanding, each Guarantor shall refrain from
taking any action or commencing any proceeding against the Borrower or any other
Obligor (or its successors or assigns, whether in connection with a bankruptcy
proceeding or otherwise) to recover any amounts in the respect of payments made
under this Guaranty to any Secured Party or any holder of a Note.

     SECTION 2.7. Successors, Transferees and Assigns; Transfers of Notes, etc.
This Guaranty shall:

          (a) be binding upon each Guarantor, and its successors, transferees
     and assigns; and

          (b) inure to the benefit of and be enforceable by the Administrative
     Agent and each other Secured Party.

Without limiting the generality of the foregoing clause (b), any Lender may
assign or otherwise transfer (in whole or in part) any Note or Credit Extension
held by it to any other Person or entity, and such other Person or entity shall
thereupon become vested with all rights and benefits in respect thereof granted
to such Lender under any Loan Document (including this Guaranty) or otherwise,
subject, however, to any contrary provisions in such assignment or transfer, and
to the provisions of Section 10.11 and Article IX of the Credit Agreement.

     SECTION 4.1. Covenants. Each Guarantor covenants and agrees that, so long
