       SECTION 5.  MISCELLANEOUS.

       5.1    CAPTIONS. The recitals to this Waiver (except for definitions) and
the section captions used in this Waiver are for convenience only and do not
affect the construction of this Waiver.

       5.2    GOVERNING LAW; SEVERABILITY. THIS WAIVER IS A CONTRACT MADE UNDER
AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF ILLINOIS. Wherever possible,
each provision of this Waiver must be interpreted in such a manner as to be
effective and valid under applicable law, but if any provision of this Waiver is
prohibited by or invalid under such law, such provision is ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of such provision or the remaining provisions of this Waiver.

       5.3    COUNTERPARTS. This Waiver may be executed in any number of
counterparts and by the different parties on separate counterparts, and each
such counterpart is deemed to be an original, but all such counterparts together
constitute but one and the same Waiver. The Credit Parties, the Agents and the
Lenders agree to accept facsimile counterparts.

       5.4    SUCCESSORS AND ASSIGNS. This Waiver is binding upon the Credit
Parties, the Agents, the Lenders and their respective successors and assigns,
and inures to the sole benefit of the Credit Parties, the Agents, the Lenders
and their successors and assigns. A Credit Party cannot assign its rights or
delegate its duties under this Waiver.

       5.5    REVIVAL OF OBLIGATIONS. If all or any part of any payment under or
on account of the Credit Agreement, the other Loan Documents, this Waiver or any
agreement, instrument or other document executed or delivered by the Credit
Parties in connection with this Waiver is invalidated, set aside, declared or
found to be void or voidable or required to be repaid to the issuer or to any
trustee, custodian, receiver, conservator, master, liquidator or any other
person pursuant to any bankruptcy law or pursuant to any common law or equitable
cause then, to the extent of such invalidation, set aside, voidness, voidability
or required repayment, such payment would be deemed to not have been paid, and
the obligations of the Credit Parties in respect thereof shall be immediately
and automatically revived without the necessity of any action by the Lenders.

       5.6    REFERENCES. From and after the Effective Date, each reference in
the Credit Agreement to "this Agreement", "hereunder", "hereof", "herein", or
words of like import, and each reference in the Credit Agreement or any other
Loan Document to the Credit Agreement, the Notes or to any term, condition or
provision contained "thereunder", "thereof", "therein", or words of like import,
mean and are a reference to the Credit Agreement or the Notes (or such term,
condition or provision, as applicable) as amended, supplemented, restated or
otherwise modified, including by this Waiver.

       5.7    CONTINUED EFFECTIVENESS. Notwithstanding anything contained in
this Waiver to the contrary, the terms of this Waiver are not intended to and do
not serve to effect a novation as to the Credit Agreement. The Credit Parties
and the Lenders expressly do not intend to extinguish the Credit Agreement.
Instead, it is the express intention of the Credit Parties and the Lenders to
reaffirm the indebtedness created under the Credit Agreement. The Credit
Agreement


                                       4
<Page>

remains in full force and effect and the terms and provisions of the
Credit Agreement are ratified and confirmed.

       5.8    INDEMNIFICATION. The Lenders shall indemnify upon demand the
Administrative Agent and its directors, officers, employees and agents (to the
extent not reimbursed by or on behalf of the Borrowers and without limiting the
obligation of the Borrowers to do so), pro rata, from and against any and all
actions, causes of actions, suits, losses, liabilities, damages and related
expenses, including reasonable attorneys' fees and charges and allocated costs
of staff counsel, of any liability of the Administrative Agent to any
independent auditor related to any tax-related services provided by such
independent auditor on behalf of the Administrative Agent and the Lenders;
PROVIDED that, no Lender shall be liable for any payment to the Administrative
Agent of any portion of the Indemnified Liabilities resulting solely from such
Person's gross negligence or willful misconduct. Without limitation of the
foregoing, each Lender shall reimburse the Agents upon demand for their ratable
share of any costs or out-of-pocket expenses (including reasonable fees of
attorneys for the Administrative Agent (including the allocable costs of
internal legal services and all disbursements of internal counsel)) incurred by
the Administrative Agent in connection with the preparation, execution,
delivery, modification, amendment or enforcement (whether through negotiations,
legal proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, the Credit Agreement, any other Loan Document or any
document contemplated by or referred to therein, to the extent that the
Administrative Agent is not reimbursed for such expenses by or on behalf of the
Borrowers. The undertaking in this SECTION 5.8 shall survive repayment of the
Loans, cancellation of the Notes, expiration or termination of the Letters of
Credit, any foreclosure under, or any modification, release or discharge of, any
or all of the Collateral Documents, any termination of the Credit Agreement and
the resignation or replacement of the Administrative Agent.

       5.9    WAIVER OF JURY TRIAL. Each of the Credit Parties, the Agents and
the each Lender waives any right to a trial by jury in any action or proceeding
to enforce or defend any rights under this Waiver, and agrees that any such
action or proceeding shall be tried before a court and not before a jury.

       5.10   WAIVER OF CLAIMS. THE CREDIT PARTIES, IN EVERY CAPACITY,
INCLUDING, BUT NOT LIMITED TO, AS SHAREHOLDERS, PARTNERS, OFFICERS, DIRECTORS,
INVESTORS AND/OR CREDITORS OF ANY CREDIT PARTY, OR ANY ONE OR MORE OF THEM,
HEREBY WAIVE, DISCHARGE AND FOREVER RELEASE EACH AGENT AND EACH LENDER AND THEIR
RESPECTIVE EMPLOYEES, OFFICERS, DIRECTORS, ATTORNEYS, STOCKHOLDERS AND
SUCCESSORS AND ASSIGNS FROM AND OF ANY AND ALL KNOWN CLAIMS, CAUSES OF ACTION,
DEFENSES, COUNTERCLAIMS OR OFFSETS AND/OR ALLEGATIONS THE CREDIT PARTIES MAY
HAVE OR MAY HAVE MADE OR THAT ARE BASED ON FACTS OR CIRCUMSTANCES OF WHICH ANY
CREDIT PARTY HAS KNOWLEDGE ARISING AT ANY TIME UP THROUGH AND INCLUDING THE DATE
OF THIS WAIVER AGAINST ANY OR ALL OF ANY AGENT, ANY LENDER, OR ANY OF THEIR
RESPECTIVE EMPLOYEES, OFFICERS, DIRECTORS, ATTORNEYS, STOCKHOLDERS AND
SUCCESSORS AND ASSIGNS.
