                  "Borrower"), the financial institutions party thereto
                  (collectively, the "Lenders"; and individually, a "Lender")

Dear Mr. Fowler:

         The Borrower, the Lenders and the Agent have entered into that certain
August 2000 Waiver Letter pursuant to which the Lenders and the Agent have
waived compliance with certain covenants set forth in the Credit Agreement. You
have advised the Lenders and the Agent that the Borrower anticipates that as of
the Waiver Expiration Date (as such term is defined in the August 2000 Waiver
Letter) the Borrower will not be back in compliance with the various financial
covenants set forth in the Credit Agreement and that the Borrower will again be
in

Page  2



default of its obligations to the Lenders thereunder. As a result, you have
asked the Lenders to consider further an amendment to the Credit Agreement to
better reflect the Borrower's present financial condition. The Lenders have
expressed to you their willingness to waive the violations of the Credit
Agreement described in Section 2 below and amend the terms of the Credit
Agreement as herein set forth.

         Accordingly, the Lenders are willing to enter into this waiver and
amendment agreement (this "November 2000 Waiver Agreement") for a period from
the date hereof until August 6, 2001 (the "Waiver Period"), provided that the
Borrower fully complies with the terms and condition hereof and the Credit
Agreement (except as expressly amended or waived hereby) during the Waiver
Period. Accordingly, the parties hereto, with the intent to be legally bound,
agree as follows:

         1. Representations and Warranties. To induce the Lenders to execute and
deliver this November 2000 Waiver Agreement, the Borrower hereby represents and
warrants to the Lenders that except as noted in the immediately succeeding
paragraph, (a) all the representations and warranties of the Borrower contained
in the Credit Agreement and any of the other Loan Documents are true and correct
in all material respects as to the Borrower on and as of the date of this
November 2000 Waiver Agreement, as though made on and as of such date, (b) no
event has occurred and is continuing or would result from the execution and
delivery of this November 2000 Waiver Agreement, which constitutes or would
constitute a Default or an Event of Default under the Credit Agreement, except
as described herein and waived hereby, and (c) each representative of the
Borrower and each Subsidiary Guarantor who executes this November 2000 Waiver
Agreement has full power and authority to enter into this November 2000 Waiver
Agreement.

         2. List of Defaults. The Borrower represents and warrants to the
Lenders that as of the date of this November 2000 Waiver Agreement the Borrower
is in default of Section 6.02 (ii) for the Fiscal Year ending July 31, 2000,
Section 6.02 (iii) for the Fiscal Year ending July 31, 2000, Section 7.12,
Section 7.13 and Section 7.14 of the Credit Agreement (the "Existing Defaults")
and no others; and the Borrower does not expect to be in compliance with the
provisions of Sections 7.12, 7.13 and 7.14 of the Credit Agreement for the
Fiscal Quarters of the Borrower ending October 31, 2000, January 31, 2001, April
30, 2001, and July 31, 2001, during the Waiver Period (the "Expected Covenant
Defaults"; and the Existing Defaults and the Expected Covenant Defaults are
herein referred to collectively as, the "Subject Defaults").

         3. Loan Balance. As of the date of this November 2000 Waiver Agreement
the Borrower is indebted to the Lenders under the Credit Agreement and the other
Loan Documents in the following amounts:

                  Principal                            $124,160,989.00

                  Accrued Interest                     $    361,404.32

                  Letters of Credit (Undrawn total)    $  6,395,330.00

                  Fees and Expenses (approximate)(1)   $    260,153.82

                                Total:                 $131,177,877.14

                  (1) Does not include fees payable under this November 2000
                  Waiver Agreement pursuant to Section 8(e).

         4. Waiver by Lenders.

                  (a) Waiver Expiration Date. For purposes of this November 2000
Waiver Agreement, the "Waiver Expiration Date" shall mean (i) the earlier of (A)
August 6, 2001; or (B) the termination of the Lenders' obligation to waive under
this November 2000 Waiver Agreement due to the occurrence of a Waiver Period
Default (as defined in Section 5 hereof) as set forth in Section 6 hereof; or
(ii) such other date as may be agreed to, in writing, by all of the Lenders and
the Borrower.

                  (b) Waiver by the Lenders. The Lenders hereby covenant and
agree that, except as otherwise expressly provided in this November 2000 Waiver
Agreement, subject to the Borrower's complete compliance with the terms and
conditions of this November 2000 Waiver Agreement and any other documents
executed in connection with this November 2000 Waiver Agreement, (i) the Lenders
shall not, prior to the Waiver Expiration Date, (x) declare the Borrower to be
in default under the Credit Agreement as a result of any violation of any
condition or covenant identified in Section 2 above as a Subject Default, or (y)
commence any enforcement action against the Borrower or any Subsidiary Guarantor
for collection of the Lender Obligations during the Waiver Period based upon a
Subject Default, (ii) each Lender, the Agent and the L/C Issuer agrees that
during the Waiver Period the determination of whether the conditions precedent
to the making of any Loans, or the issuance of any Letter of Credit, shall be
made without regard to the existence (whether now or in the future) of any of
the Subject Defaults, and (iii) the Lenders, the Agent, the L/C Issuer and the
Borrower hereby acknowledge and agree that the extension of Swingline Loans by
the Agent is made solely in the discretion of the Agent, subject to the other
terms and conditions of the Credit Agreement. The Borrower expressly
acknowledges and agrees that from and after the Waiver Expiration Date the
Lenders shall have the right, at any time and from time to time, without the
benefit to the Borrower of further opportunity to cure, or to receive further
notice of, a Subject Default or both, to exercise any and all rights and
remedies available to them against the Borrower, at law and in equity, to
<PAGE>   4

Page  4



the same extent as the Lenders would be entitled if the foregoing waiver had
never been part of this November 2000 Waiver Agreement. Each of the Subject
Defaults shall be deemed to have occurred and be continuing unless the Borrower
delivers to the Lenders prior to the Waiver Expiration Date a certificate
executed by the Borrower's chief financial officer stating that one or more of
the Subject Defaults do not exist under the Credit Agreement or the other Loan
Documents as of the date of that certificate. In the event that the Borrower
shall have reduced (i) on or before March 31, 2001 (or as such date may be
extended due to a Permitted Sale Delay to April 30, 2001), the Revolving Credit
Commitment to $110,000,000.00, or (ii) on or before July 31, 2001, the Revolving
Credit Commitment to $85,000,000.00, in each such circumstance the Lenders, the
Agent and the L/C Issuer agree to negotiate in good faith to establish new
financial covenants addressing the changes in the level of consolidated assets
and the earnings potential of the Borrower and its consolidated Subsidiaries.
The Borrower also agrees to proceed with due diligence and in good faith to
obtain alternate financing to the credit accommodations available under the
Credit Agreement on or before July 31, 2001.

                  (c) Exercise of Rights By the Lenders prior to the Waiver
Expiration Date. The Borrower understands and agrees that the waiver by the
Lenders set forth in Section 4(b) does not relate or extend to any actions that
the Lenders may take under the Loan Documents or at law or in equity to preserve
or protect the collateral provided for in the Security Documents (the
"Collateral") and the interest of the Agent and the Lenders in the Collateral,
including, by way of example and not limitation, (i) filing actions against or
defending or intervening in actions brought by third parties, including but not
limited to any and each Subsidiary Guarantor relating to the Collateral or the
interests of the Agent and the Lenders therein, (ii) the sending of notices to
any persons or entities concerning the existence of security interests or liens
in favor of the Agent and the Lenders or concerning any of the Collateral, (iii)
filing or recording financing statements, continuation statements, amendments,
revivals or any other documents, or taking other actions to evidence,
effectuate, establish, perfect, maintain or continue the Lenders' security
interests or liens in the Collateral, (iv) taking such action as the Lenders
deem necessary or appropriate in the Borrower's or any Subsidiary Guarantor's
bankruptcy, or (v) taking of such action as the Lenders deem necessary or
appropriate with respect to any other person or entity not a party to this
November 2000 Waiver Agreement.

         5. Waiver Defaults. For purposes of this November 2000 Waiver
Agreement, each of the events described in this Section 5 shall constitute a
"Waiver Period Default."

                  (a) Misrepresentation. Any representation or warranty of the
Borrower, or any Subsidiary Guarantor, in this November 2000 Waiver Agreement or
any Loan Document, proves to have been untrue in any material respect as of the
date when made, or any certificate or other document furnished by the Borrower
to the Agent or the Lenders pursuant to the provisions

Page  5



hereof or thereof proves to have been untrue in any material respect on the date
as of which the facts set forth therein are stated or certified.

                  (b) Breach of Covenants. (i) The Borrower or any Subsidiary
Guarantor shall default in the performance of its covenants set forth at
Subsection 8(c) through Subsection 8(q) inclusive and Subsection 8(w) of this
November 2000 Waiver Agreement; or (ii) the Borrower or any Subsidiary Guarantor
shall breach or default under or fail to fully perform any of their respective
other agreements, obligations and covenants under this November 2000 Waiver
Agreement or any of their respective agreements, obligations and covenants under
the Credit Agreement, or any Loan Document, or the documents executed pursuant
to or in connection herewith or therewith, other than the occurrence or
existence of any of the Subject Defaults or any default described in clause (i)
of this Subsection 5(b) of this November 2000 Waiver Agreement, and the
continuance of such breach or default or failure to perform beyond the period of
grace, if any, allowed with respect thereto under the applicable Loan Document.

                  (c) Breach of Other Lender Agreements. The Borrower, or any
Subsidiary Guarantor, shall breach, default under or fail to perform any other
agreements or contracts, other than the Loan Documents, with any of the Lenders
or any of the Lenders' respective affiliates or subsidiaries; and if such
breach, default or failure to perform involves a failure to make a timely
payment under the applicable agreement or contract, such breach, default or
failure to perform shall continue unremedied for a period of the earlier of (i)
ten (10) days after its due date plus any applicable grace period provided under
the applicable agreement or contract or (ii) the date of the acceleration of, or
the exercise of collection remedies with respect to, the indebtedness of the
Borrower or any Subsidiary Guarantor due under such agreement or contract; and
if such breach, default or failure to perform involves a breach of non-payment
term of the applicable agreement or contract, such breach, default or failure to
perform shall continue unremedied for a period of (x) the earlier of thirty (30)
days after written notice to the Borrower, or (y) the date of the acceleration
of, or the exercise of collection remedies with respect to, the indebtedness of
the Borrower or any Subsidiary Guarantor under such agreement or contract.

                  (d) Bankruptcy or Insolvency. The Borrower or any Subsidiary
Guarantor shall file a petition in bankruptcy under any chapter of the
Bankruptcy Code (Title 11, U.S.C. Section 101 et seq.), or shall make any
general assignment for the benefit of creditors, or shall file any petition
seeking reorganization, liquidation, dissolution or similar relief under any
present or future federal, state or local law or regulation relating to
bankruptcy, insolvency or other relief for debtors, or shall fail generally to
pay its respective debts as they become due.

                  (e) Judgment, Tax Lien or Forfeiture Against the Borrower.
Execution is issued on any judgment against the Borrower or any Subsidiary
Guarantor in excess of $500,000 or any levy, forfeiture, seizure or attachment
is made against assets of the Borrower or any

Subsidiary Guarantor in excess of $500,000 or any federal or state tax lien is
filed against the Borrower or any Subsidiary Guarantor in excess of $500,000.

                  (f) Suit Against the Lenders. The Borrower, or any Subsidiary
Guarantor, shall file or institute against the Lenders or the Agent or any of
their respective officers, directors, employees, agents or attorneys any
lawsuit, complaint, administrative claim, adversary proceeding or other legal
action.

         6. Remedies.

                  (a) Automatic Termination of Waiver. Upon the occurrence of a
Waiver Period Default under Section 5(d) hereof, the agreement of the Lenders to
waive pursuant to Section 4(b) hereof and any and all other obligations of the
Lenders pursuant to this November 2000 Waiver Agreement, shall immediately
terminate and be without further force and effect in the same manner and to the
same extent as if the same had never been included in this November 2000 Waiver
Agreement. In addition, upon the occurrence of any such Waiver Period Default,
all Lender Obligations shall be deemed immediately due and payable without
necessity of demand, presentment, protest, notice of dishonor or notice of
default. No full or partial exercise of any right or remedy shall be deemed a
waiver of any other right or remedy. The Lenders shall without further notice be
entitled to exercise any and all rights and remedies of the Lenders against the
Borrower, and/or the Subsidiary Guarantor, provided for under the Credit
Agreement, or in the other Loan Documents, or in any other manner available at
law or in equity, including, by way of example and not limitation, the Lenders'
right to obtain a judicial sale, either by foreclosure or execution proceeding,
of any property subject to any mortgage or judgment.

                  (b) Additional Termination of Waiver. Upon the occurrence of a
Waiver Period Default under Section 5(a), 5(b), 5(c), 5(e) or 5(f) hereof and
the continuance of such Waiver Period Default for a period of thirty (30) days
without the applicable remedy, waiver or cure, the waiver agreement of the
Lenders pursuant to Section 4(b) hereof and any and all other obligations of the
Lenders pursuant to this November 2000 Waiver Agreement shall be terminated and
be without further force and effect. Upon such termination of the Waiver Period
and upon declaration of acceleration in accordance with the Credit Agreement,
the amounts due by the Borrower to Lenders under the Credit Agreement and the
other Loan Documents shall be deemed immediately due and payable without
necessity of further presentment, presentation, protest, notice of dishonor or
notice of default. No full or partial exercise of any right or remedy shall be
deemed a waiver of any other right or remedy. Thereafter, the Lenders shall
without further notice be entitled to exercise any and all rights and remedies
of the Lenders against the Borrower and/or the Subsidiary Guarantors provided
for under the Credit Agreement or in the other Loan Documents, or in any other
manner available at law or in equity, including, by way of

example and not limitation, the Lenders' right to obtain a judicial sale, either
by foreclosure or execution proceeding, of any property subject to any lien,
mortgage or judgment.

         7. Extent of Waiver. Except as expressly described herein, this
November 2000 Waiver Agreement shall not constitute (a) a modification or an
alteration of any of the terms, conditions or covenants of the Credit Agreement,
all of which remain in full force and effect, or (b) a waiver, release or
limitation upon the Agent's or any Lender's exercise of any of its rights and
remedies thereunder, all of which are hereby expressly reserved. This November
2000 Waiver Agreement shall not relieve or release the Borrower in any way from
any of its duties, obligations, covenants or agreements under the Credit
Agreement or from the consequences of any Default or Event of Default
thereunder, except as expressly described herein. This November 2000 Waiver
Agreement shall not obligate the Agent or any Lender, or be construed to require
the Agent or any Lender, to waive any other Events of Default or Defaults under
the Credit Agreement, whether now existing or which may occur after the date of
this November 2000 Waiver Agreement.

                  Except as expressly waived or amended hereby, the Credit
Agreement and each and every representation, warranty, agreement, covenant, term
and condition contained therein or in any other Loan Document is specifically
ratified and confirmed. Nothing in this November 2000 Waiver Agreement shall be
deemed or construed to be a waiver or release of, or a limitation upon, the
Agent's or any Lender's exercise of any of its rights and remedies under the
Credit Agreement or the other Loan Documents except as expressly set forth
herein.

         8. Covenants and Obligations.

Revolving Credit Commitment is permanently reduced to $85,000,000 and Total
Utilization does not exceed $85,000,000 (and in the event that immediately prior
to the issuance or sale of an Equity Interest, the Borrower has reduced

capital stock of (or other ownership or profit interests in) such Person,
securities convertible into or exchangeable for shares of capital stock of (or
other ownership or profit interests in) such Person or warrants, rights or
options for the purchase or other acquisition from such Person of such shares
(or such other interests), and other ownership or profit interests in such

rights or other interests are authorized or otherwise existing on any date of

Notwithstanding any other provisions of the Credit Agreement to the contrary,
(i) on April 1, 2001 and on the first day of each month thereafter, the
Revolving Credit Commitment shall reduce by $500,000 per month, and (ii) on each
date of the payment of any BOC Refund to the Borrower, the Borrower shall
further permanently reduce the Revolving Credit Commitment by 2/3 of the amount
of such BOC refund payment. To accomplish any reduction to the Revolving Credit
Commitment set forth in this Section 8(q), the requirements of Section 2.04(a)
of the Credit Agreement (x) that reduction in the Revolving Credit Commitment
occur in the minimum amount of $5,000,000 and increments of $1,000,000 for any
reduction in excess of $5,000,000, and (y) that such reduction be made only with
five (5) Business Days prior notice, are each hereby waived. At no time
following any reduction in the Revolving Credit Commitment required by this
Section 8(q) shall Total Utilization exceed such reduced Revolving Credit
Commitment.
