           of total Capital Expenditures at the time the sale-leaseback
           arrangement becomes effective, and (d) to the extent the purchase
           price of any equipment that subsequently becomes subject to a Capital
           Lease pursuant to a sale-leaseback arrangement permitted under

                   "9.23 Sale-of Assets. No Company shall sell, assign,
                         --------------

                   any sale-leaseback arrangement with any Person pursuant to
                   which such Company shall lease any asset (whether now owned
                   or hereafter acquired) if such asset has been or is to be
                   sold or transferred by any Company to any other Person;
                   provided that, notwithstanding the foregoing, any Company may
                   enter into a sale-leaseback arrangement with respect to
                   equipment acquired by any Company no more than 180 days prior
                   to entering into such sale-leaseback arrangement, so long as
                   the aggregate purchase price originally paid by any Company
                   for the subject equipment for all such sale-leaseback
                   arrangements during any fiscal year does not exceed

                        --------------------
                   2000, the Companies shall not make Capital Expenditures in
                   any two consecutive fiscal years if the aggregate amount of
                   such expenditures would exceed $100,000,000."

          (i)      Schedule 2.1 is entirely deleted and replaced with the

          -------------------------------------------------------
3.
(a)       Effective on and after the Restatement Effective Date (as such term is
defined in Paragraph 1, and herein so called), each Increasing Lender agrees
that its Committed Sum under the Revolver Facility shall be increased to the
amount corresponding to the Revolver Facility set forth opposite its name on
Replacement Schedule 2.1 attached hereto. Accordingly, each Revolver Lender's
Commitment Percentage shall be recalculated to reflect the new proportionate
share of the revised Revolver Commitment as stated on Replacement Schedule 2.1.

(a)       Furthermore, to the extent any Revolver Principal Debt is outstanding
on the Restatement Effective Date (excluding any Revolver Loans made on such
date), then on such date, each Increasing Lender shall pay to Administrative
Agent (for ratable distribution to the other Revolver Lenders) an amount equal
to its Commitment Percentage of the Revolver Principal Debt then outstanding,
which is deemed assumed and purchased from the other Revolver Lenders. All such
payments shall reduce the Revolver Principal Debt owed to each Revolver Lender
receiving such payments and shall represent a Borrowing under the Revolver
Facility by Borrower from the appropriate Increasing Lender. On and after the
Restatement Effective Date, the Increasing Lenders shall be entitled to share
ratably in interest accruing in accordance with the Loan Documents.
(b)
(c)       To the extent a payment contemplated in Paragraph 2(b), if any, occurs
on a date other than the last day of any Interest Period for any outstanding
Eurodollar Rate Borrowing, Borrower agrees to pay to each Lender (upon the
request of each such Lender) the amounts required by Section 5.5(a) in
connection therewith.
(d)
2.        Conditions Precedent.   Notwithstanding any contrary provision, this
          --------------------
Agreement is not effective until the date upon which Administrative Agent
receives all of the following (each in form and substance acceptable to
Administrative Agent):
3.
(a)       This Agreement.  Counterparts of this Agreement (together with all
          --------------
Schedules and Exhibits) executed by Borrower, Administrative Agent, Required
Lenders, Increasing Lenders, and Guarantors;

<PAGE>

(b)
(c)       Notes.  With respect to any Increasing Lender and only to the extent
          ------
requested pursuant to Section 3.1(b), a replacement Revolver Note substantially
in the form of Exhibit A-1 payable to such requesting Increasing Lender;
(d)
(e)       Officers' Certificates. Officers' Certificates of Borrower and of each
          ----------------------
Guarantor (i) certifying that there have been no changes to its Articles of
Incorporation and Bylaws since the date of their last certification pursuant to
the Loan Documents, (ii) confirming the continued incumbency of its officers
since the date of their last certification pursuant to the Loan Documents, and
(iii) certifying copies of resolutions duly adopted by its Board of Directors
approving this Agreement and the other Loan Documents and authorizing the
transactions contemplated in such Loan Documents;
(f)
(g)       Payment of Fees and Expenses.  Payment of all unpaid fees and expenses
          ----------------------------
payable on or prior to the date hereof to Administrative Agent, including,
without limitation, fees and expenses of counsel pursuant to Paragraph 5(c).
(h)
(i)       Opinion. Opinion of Borrower's counsel addressed to Administrative
          -------
Agent and Lenders, in form and substance satisfactory to Administrative Agent.
(j)
(k)       Other Documents. Such other agreements, documents, instruments,
          ---------------
opinions, certificates, and evidences as Administrative Agent may reasonably
request. Administrative Agent shall, upon request of Borrower, confirm to
Borrower that it has received all such items so requested.
(l)
4.        Waiver.
          ------
5.
(a)       Borrower's Waiver Request. Borrower has informed Administrative Agent
          -------------------------
that it has formed three new Domestic Subsidiaries (the "Subject Domestic
Subsidiaries") as set forth on the attached Replacement Schedule 8.3 and has
transferred certain assets of one or more previously existing Domestic
Subsidiaries to one or more of the Subject Domestic Subsidiaries, but, in
connection therewith, has inadvertently failed to comply with the provisions of
Section 9.16 (Permitted Acquisitions, Subsidiary Guaranties, and Collateral
Documents), Section 9.20 (Loans, Advances, and Investments), and Section 9.23
(Sale of Assets) in a timely manner (the "Subject Noncompliance"). Borrower has
requested that Required Lenders waive the Subject Noncompliance. Required
Lenders are willing to grant and agree to such waver, subject to and upon the
terms and conditions set forth in Paragraph 4.
(b)
(c)       Waiver and Conditions. Required Lenders waive any Default or Potential
          ---------------------
Default that may exist or arise solely as a result of the Subject Noncompliance
and agree that Lenders will not exercise their Rights under the Loan Documents
solely as a result of the Subject Noncompliance; provided, however, that, the
waiver herein granted is expressly conditioned upon the requirement that
Borrower shall have satisfied the requirements of Sections 9.16, 9.20, and 9.23
no later than January 26, 2001. Except as expressly stated, this Paragraph 4 is
not a waiver of existing or future Defaults or Potential Defaults or a waiver of
Administrative Agent's or any Lender's Rights to insist upon compliance by all
relevant parties with each Loan Document. The failure of Borrower to comply with
the conditions or limitations set forth in this Paragraph 4 shall constitute a
Default entitling Lenders to exercise their respective Rights under the Loan
Documents. The waiver under this Paragraph 4 is expressly subject to the
condition that no Default or Potential Default now exists or will arise as a
result of the formation of the Subject Domestic Subsidiaries, other than
Defaults or Potential Defaults expressly waived in accordance with the Loan
Documents.
