         2.       Subordination.

                  (a) The Borrowers and the Subordinated Lender, for itself and
each future holder of the Subordinated Obligations, agree that the Subordinated
Obligations are expressly "subordinate and junior in right of payment" (as that
phrase is defined in paragraph 2(b)) to all Senior Obligations.

                           (i) no part of the Subordinated Obligations shall
         have any claim to the assets of a Borrower on a parity with or prior to
         the claim of the Senior Obligations;

                           (ii) unless and until the Senior Obligations have
         been paid in full and the Senior Lenders' commitments to make loans
         under the Senior Credit Agreement have been terminated, without the

         Lender will not take, demand, or receive from a Borrower, and a
         Borrower will not make, give or permit, directly or indirectly, by

         Period, a Borrower may make, and the Subordinated Lender may receive,
         payments on account of principal and interest on the Subordinated
         Loans;


                                        4
<PAGE>   5
                           (iii) unless and until the Senior Obligations have
         been paid in full and the Senior Lenders' commitments to make loans
         under the Senior Credit Agreement have been terminated, the
         Subordinated Lender will not commence or participate in any suit or
         action to enforce payment of any part or all of the Subordinated
         Obligations;

                           (iv) none of the provisions of subsections 2(b)(iii)
         or (iv) above or elsewhere in this Agreement shall in any way derogate
         from or diminish the absolute subordination provided under items
         2(b)(i) and (ii) above or under Section 3 below.

                  (c) Upon the termination of any Blockage Period, the
Subordinated Lender's rights to receive principal and interest payments as
provided in subsection 2(b)(ii) above shall be reinstated, and a Borrower may
resume making such payments to the Subordinated Lender to the extent provided in
such subsection 2(b)(ii).

                  (d) The Agent shall be entitled to deliver a separate Blockage
Notice with respect to any or all Events of Default and each such Blockage
Notice shall be effective as provided in this Agreement.

                  (e) A Blockage Period shall be effective without the delivery
of a Blockage Notice if (i) the events which would have been set forth in the
Blockage Notice have occurred and (ii) such Blockage Notice may not be given
because of the automatic stay under 11 U.S.C. 362 or any successor statute, or
the Subordinated Lender has actual notice of an Event of Default.

                  (f) The expressions "prior payment in full," "payment in
full," "paid in full" and any other similar terms or phrases when used herein
with respect to the Senior Obligations shall mean the payment in full, in
immediately available funds, of all of the Senior Obligations.

                  (g) The Subordinated Lender hereby represents and warrant that
as of the date hereof, the Borrowers have no obligations to the Subordinated
Lender.

         3.       Additional Provisions Concerning Subordination.

                  (a) The Subordinated Lender and the Borrowers agree that upon
the occurrence of any Insolvency Event:

                           (i) all Senior Obligations shall be paid in full
         before any payment or distribution (other than a distribution of
         securities which are subordinate to the payment of all Senior
         Obligations then outstanding) is made with respect to the Subordinated
         Obligations; and

                           (ii) any payment or distribution of assets of a
         Borrower, whether in cash, property or securities (other than a
         distribution of securities which are subordinate


                                        5
<PAGE>   6
         to the payment of all Senior Obligations then outstanding), to which
         the Subordinated Lender would be entitled except for the provisions
         hereof, shall be paid or delivered by such Borrower, or any receiver,
         trustee in bankruptcy, liquidating trustee, disbursing agent or other
         Person making such payment or distribution, directly to the Agent, to
         the extent necessary to pay in full all Senior Obligations, before any
         payment or distribution shall be made to the Subordinated Lender.

                  (b) The Subordinated Lender will not commence or join with any
other creditor or creditors of a Borrower in commencing any bankruptcy,
reorganization or insolvency proceedings against a Borrower. At any meeting of
creditors of a Borrower or in the event of any proceeding, voluntary or
involuntary, for the distribution, division or application of all or part of the
assets of a Borrower or the proceeds thereof, whether such proceeding be for the
liquidation, dissolution or winding up of a Borrower or its business, a
receivership, insolvency or bankruptcy proceeding, an assignment for the benefit
of creditors or a proceeding by or against a Borrower for relief under any
bankruptcy, reorganization or insolvency law or any law relating to the relief
of debtors, readjustment of indebtedness, reorganization, arrangement,
composition or extension or otherwise, if all Senior Obligations have not been
paid in full at the time, the Agent is hereby irrevocably authorized at any such
meeting or in any such proceeding:

                           (i) To enforce claims comprising Subordinated
         Obligations either in its own name or the name or names the
         Subordinated Lender, by proof of debt, proof of claim, suit or
         otherwise;

                           (ii) To collect any assets of a Borrower distributed,
         divided or applied by way of dividend or payment, or any such
         securities issued, on account of Subordinated Obligations and apply the
         same, or the proceeds of any realization upon the same that the Agent
         in its discretion elects to effect, to Senior Obligations until all
         Senior Obligations shall have been paid in full, rendering any surplus
         to the Subordinated Lender, pro rata;

                           (iii) To vote claims comprising Subordinated
         Obligations to accept or reject any plan of partial or complete
         liquidation, reorganization, arrangement, composition, extension or
         otherwise; and

                           (iv) To take generally any action in connection with
         any such meeting or proceeding which the Subordinated Lender might
         otherwise take.

                  (c) If any payment from a Borrower shall be collected or
received by the Subordinated Lender in respect of the Subordinated Obligations,
except payments permitted to be made at the time of payment as provided in this
Agreement, the Subordinated Lender forthwith shall deliver the same to the
Agent, in the form received, duly endorsed to the Agent, if required, to be
applied to the payment or prepayment of the Senior Obligations until the Senior
Obligations are paid in full. Until so delivered, such payment or distribution
shall


                                        6
<PAGE>   7
be held in trust by the Subordinated Lender as the property of the Agent,
segregated from other funds and property held by the Subordinated Lender. Until
the Senior Obligations are paid in full, the Subordinated Lender shall not have
any right of subrogation, reimbursement, restitution, contribution or indemnity
whatsoever from any assets of a Borrower or any guarantor or provider of
collateral security for the Senior Obligations.

         4.       Legend. The Subordinated Lender shall cause a conspicuous
legend to be placed on each Subordinated Note to the following effect:

                  "This Note, and the indebtedness evidenced hereby, is
         subordinate and junior in right of payment in the manner and to the
         extent set forth in an agreement (the "Subordination Agreement") dated
         as of July 20, 1998 originally made by the maker and payee of this Note
         in favor of the Senior Lenders to all indebtedness at any time owed by
         the maker of this Note to such Bank (or to its successor and assigns or
         subsequent holder of "Senior Obligations" as defined in the
         Subordination Agreement), and each holder of this Note, by its
         acceptance hereof, shall be bound by the Subordination Agreement, and
         this Note may be sold or otherwise transferred only in compliance with
         the conditions specified in the Subordination Agreement."

         5.       Liens. The Subordinated Lender shall not have or claim any
security interest, lien, claim, right or other encumbrance in or on any property
of a Borrower on account of the Subordinated Obligations. The Subordinated
Lender hereby agrees, upon request of the Senior Lender at any time and from
time to time, to execute such other documents or instruments as may be requested
by the Agent further to evidence of public record or otherwise the senior
priority of the Senior Obligations as contemplated by this Agreement, and to
execute a subordination agreement on similar terms in favor of any successors or
assigns of the Agent or other lender extending credit to a Borrower in exchange
or replacement of the Senior Obligations.

         6.       Consent of Subordinated Lender.

                  (a) The Subordinated Lender consents that, without the
necessity of any reservation of rights and without notice to or further assent:

                           (i) any demand for payment of any Senior Obligations
         made by the Agent or the Senior Lenders may be rescinded in whole or in
         part by the Agent or the Senior Lenders, and any Senior Obligation may
         be continued, and the Senior Obligations, or the liability of a
         Borrower or any guarantor or any other party upon or for any part
         thereof, or any collateral security or guarantee therefor or right of
         offset with respect thereto, or any obligation or liability of a
         Borrower or any other party under the Senior Credit Agreement or any
         other agreement, may, from time to time, in whole or in part, be
         renewed, extended, modified, accelerated, compromised, waived,
         surrendered, or released by the Agent or the Senior Lenders; and


                                        7
<PAGE>   8
                      (ii) the Senior Credit Agreement, the Senior Notes, any
         other Senior Loan Document and the Senior Obligations may be amended,
         modified, supplemented or terminated, in whole or in part, as the Agent
         or the Senior Lenders may deem advisable from time to time, and any
         collateral security at any time held by the Agent or the Senior Lenders
         for the payment of any of the Senior Obligations may be sold,
         exchanged, waived, surrendered or released,

in each case all without notice to or further assent by the Subordinated Lender,
which will remain bound under this Agreement, and all without impairing,
abridging, releasing or affecting the subordination provided for herein.

                  (b) The Subordinated Lender waives any and all notice of the
creation, renewal, extension or accrual of any of the Senior Obligations and
notice of or proof of reliance by the Agent or the Senior Lenders upon this
Agreement. The Senior Obligations, and any of them, shall be deemed conclusively
to have been created, contracted or incurred in reliance upon this Agreement,
and all dealings between a Borrower and the Agent or the Senior Lenders shall be
deemed to have been consummated in reliance upon this Agreement. The
Subordinated Lender acknowledges and agrees that the Agent and the Senior
Lenders have relied upon the subordination provided for herein in entering into
the Senior Credit Agreement and in making funds available to a Borrower
thereunder. The Subordinated Lender waives notice of or proof of reliance on
this Agreement and protest, demand for payment and notice of default.

         7.       Senior Obligations Unconditional. All rights and interests of
the Agent and the Senior Lenders hereunder, and all agreements and obligations
of the Subordinated Lender and the Borrowers hereunder, shall remain in full
force and effect irrespective of:

                  (a) any lack of validity or enforceability of any Senior
         Security Documents or any other Senior Loan Documents;

                  (b) any change in the time, manner or place of payment of, or
         in any other term of, all or any of the Senior Obligations, or any
         amendment or waiver or other modification, whether by course of conduct
         or otherwise, of the terms of the Senior Credit Agreement or any other
         Senior Security Document;

                  (c) any exchange, release or nonperfection of any security
         interest in any Collateral, or any release, amendment, waiver or other
         modification, whether in writing or by course of conduct or otherwise,
         of all or any of the Senior Obligations or any guarantee thereof, or

                  (d) any other circumstances which otherwise might constitute a
         defense available to, or a discharge of, a Borrower in respect of the
         Senior Obligations, or of either any Subordinated Lender or a Borrower
         in respect of this Agreement.


                                        8
<PAGE>   9
         8.       Waiver of Claims. To the maximum extent permitted by law, the
Subordinated Lender waives any claim it might have against the Agent or the
Senior Lenders with respect to, or arising out of, any action or failure to act
or any error of judgment, negligence, or mistake or oversight whatsoever on the
part of the Agent or the Senior Lenders or their respective directors, officers,
employees or agents with respect to any exercise of rights or remedies under the
Senior Loan Documents or any transaction relating to the Collateral. Neither the
Agent or the Senior Lenders nor any of their directors, officers, employees or
agents shall be liable for failure to demand, collect or realize upon any of the
Collateral or for any delay in doing so or shall be under any obligation to sell
or otherwise dispose of any Collateral upon the request of a Borrower or the
Subordinated Lender or any other Person or to take any other action whatsoever
with regard to the Collateral or any part thereof.

         9.       Extension of Senior Obligations. Notwithstanding the foregoing
provisions of this Agreement and any extension by the Agent or the Senior
Lenders of the final maturity date of the Senior Obligations, provided that at
the time no Event of Default under the Senior Loan Documents is continuing, the
Subordinated Lender may receive timely payment of all unpaid principal and
accrued interest on the Subordinated Obligations. In the event an Event of
Default does then exist, the subordination of the Subordinated Obligations under
Section 2(b)(i), (ii) and (iii) and Section 3 shall remain in effect and
unimpaired.

         10.      Provisions Applicable After Bankruptcy. The provisions of this
Agreement shall continue in full force and effect notwithstanding the occurrence
of and from and after any "Insolvency Event."

         11.      Further Assurances. The Subordinated Lender and the Borrowers,
at their own expense and at any time from time to time, upon the written request
of the Agent or the Senior Lenders will promptly and duly execute and deliver
such further instruments and documents and take such further actions as any
Senior Lender or any successor lender reasonably may request for the purposes of
obtaining or preserving the full benefits of this Agreement and of the rights
and powers herein granted.

         12.      Provisions Define Relative Rights. This Agreement is intended
solely for the purpose of defining the relative rights of the Agent or the
Senior Lenders or any successor lenders on the one hand and the Subordinated
Lender and the Borrowers, and no other Person shall have any right, benefit or
other interest under this Agreement.

         13.      Powers Coupled With An Interest. All powers, authorizations
and agencies contained in this Agreement are coupled with an interest and are
irrevocable until the Senior Obligations are paid in full and the Senior
Lenders' commitments to make loans to the Borrowers are terminated.

         14.      Notices. All notices, requests and demands to or upon the
Agent or the Senior Lenders or the Borrowers or the Subordinated Lender to be
