                  (iii)    upon the payment or prepayment (whether mandatory or
                           optional) of any Loan or the Conversion of any Loan
                           to a Loan of the other Type (but only on the
                           principal amount so paid, prepaid or Converted); and

                  (iv)     on the Maturity Date.

         Section 2.5 Borrowing Procedure. The Borrower shall give the
Administrative Agent notice of each borrowing hereunder in accordance with

the Principal Office, in immediately available funds, for the account of the
Borrower. The amount of each borrowing hereunder so received by the
Administrative Agent shall, subject to the terms and conditions of this
Agreement, be made available to the Borrower by wire transfer of immediately
available funds to the Deposit Account no later than 1:00 p.m. (Dallas, Texas

of the additional compensation specified in Section 4.5, (c) except for
Conversions of Eurodollar Loans into ABR Loans, no Conversions or Continuations
shall be made while a Default has occurred and is continuing, and (d) optional
prepayments of the Loans shall be applied first to the installments of principal
due under the Amortizing Loan Portion of the Loans in the inverse order of the
maturities of such installments and thereafter to the outstanding principal of
the Revolving Loan Portion of the Loans; provided, however, that if the Borrower
specifically requests that such prepayment be applied to the Revolving Loan
Portion of the Loans prior to or concurrently with the making of such
prepayment, then such prepayment shall be applied first to the outstanding
principal of the Revolving Loan Portion of the Loans and thereafter to the
installments of principal due under the Amortizing Loan Portion of the Loans in
the inverse order of the maturities of such installments.

integral multiple of $500,000 in excess thereof (borrowings, prepayments or
Conversions of or into Loans of different Types or, in the case of Eurodollar

Each such notice which includes reference to the duration of an Interest Period
shall specify the Loans to which such Interest Period is to relate. The
Administrative Agent shall promptly notify the Lenders of the contents of each
such notice. In the event the Borrower fails to select the Type of Loan within
the time period and otherwise as provided in this Section 2.8, such Loan (if
outstanding as a Eurodollar Loan) will be automatically Converted into an ABR
Loan on the last day of the preceding Interest Period for such Loan or (if
outstanding as an ABR Loan) will remain as, or (if not then outstanding) will be

<PAGE>
         (a) The Borrower hereby represents and warrants that all proceeds of
the Loans made prior to the Closing Date were used for one or more of the
purposes permitted by Section 2.9 of the Existing Agreement.

         (b) The Borrower agrees that all proceeds of the Loans to be made on or
after the Closing Date shall be used by the Borrower and its Subsidiaries for
working capital and general corporate purposes in the ordinary course of
business and to finance acquisitions permitted by this Agreement and Capital
Expenditures permitted by this Agreement.

         (c) None of the proceeds of any Loan have been or will be used to
acquire any security in any transaction that is subject to Section 13 or 14 of
the Exchange Act or to purchase or carry any margin stock (within the meaning of
Regulations T, U or X of the Board of Governors of the Federal Reserve System).

         Section 2.10 Fees.

         (a) Subject to Section 13.12, the Borrower agrees to pay to the
Administrative Agent for the account of each Lender a commitment fee on the
daily average unused or unfunded amount of such Lender's Commitment, for the
period from and including the Closing Date to and including the Revolving Period
Termination Date, at the Commitment Fee Rate per annum based on a 360 day year
and the actual number of days elapsed, which accrued commitment fees shall be
payable in arrears on each Quarterly Date and on the Revolving Period
Termination Date.

         (b) Subject to Section 13.12, the Borrower agrees to pay to the
Administrative Agent for the account of each Lender which is a party hereto as
of the Closing Date an up-front/extension fee in the amount set forth in the
Administrative Agent's Letter, which fee shall be payable in full on the Closing
Date.

         (c) Subject to Section 13.12, the Borrower agrees to pay to the
Administrative Agent, Bank of America and Banc of America Securities LLC such
additional fees as are specified in the Administrative Agent's Letter, which

(or, if the date for payment of a fee is not specified thereon, on the Closing
Date).

         Section 2.11 Computations. All interest and fees payable by the
Borrower hereunder and under the other Loan Documents shall be computed on the
basis of a year of 360 days and the actual number of days elapsed (including the
first day but excluding the last day) occurring in the period for which payable
unless, in the case of interest, such calculation would result in a usurious
rate, in which case interest shall be calculated on the basis of a year of 365
or 366 days, as the case may be; provided, however, that interest accrued and/or
payable with respect to the ABR Loans shall be calculated on the basis of a year
of 365 or 366 days, as the case may be.

         Section 2.12 Termination or Reduction of Commitments. The Borrower
shall have the right to terminate or reduce in part the unused portion of the
Commitments at any time and from time to time prior to the Revolving Period
Termination Date, provided that (a) the Borrower shall

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 39
<PAGE>
give notice of each such termination or reduction as provided in Section 2.8,
and (b) each partial reduction shall be in an aggregate amount at least equal to
$1,000,000 or an integral multiple of $100,000 in excess thereof. The
Commitments may not be reinstated after they have been terminated or increased
after they have been reduced.

         Section 2.13 Letters of Credit.

         (a) Subject to the terms and conditions of this Agreement, the Borrower
may utilize the Commitments by requesting that the Issuing Bank issue Letters of
Credit; provided, that the aggregate amount of outstanding Letter of Credit
Liabilities shall not at any time exceed $5,000,000 (inclusive of Letter of
Credit Liabilities in the aggregate amount of $3,134,000 attributable to Letters
of Credit issued prior to the Closing Date as referred to below). Upon the date
of issue of each Letter of Credit, the Issuing Bank shall be deemed, without
further action by any party hereto, to have sold to each Lender, and each Lender
shall be deemed, without further action by any party hereto, to have purchased
from the Issuing Bank, a participation to the extent of such Lender's Commitment
Percentage in such Letter of Credit. Notwithstanding anything to the contrary
contained in this Agreement, Letter of Credit Liabilities in the aggregate
amount of $3,134,000 attributable to Letters of Credit issued prior to the
Closing Date which remain outstanding as of the Closing Date shall be deemed to
be Letter of Credit Liabilities outstanding under, and Letters of Credit issued
under, respectively, this Agreement.

         (b) The Borrower shall give the Issuing Bank (with a copy to the
Administrative Agent) at least five Business Days irrevocable prior notice
(effective upon receipt) specifying the date of each Letter of Credit and the
nature of the transactions to be supported thereby. Upon receipt of such notice
the Issuing Bank shall promptly notify each applicable Lender of the contents
thereof and of such Lender's Commitment Percentage of the amount of the proposed
Letter of Credit. Each Letter of Credit shall have an expiration date that does
not exceed one year from the date of issuance and that does not extend beyond
the Maturity Date, shall be payable in Dollars, shall support a transaction
entered into in the ordinary course of the Borrower's or its Wholly-Owned
Subsidiary's business, shall be satisfactory in form and substance to the
Issuing Bank, and shall be issued pursuant to such agreements, documents and
instruments (including a Letter of Credit Agreement) as the Issuing Bank may
reasonably require, none of which shall be inconsistent with this Section 2.13.
Each Letter of Credit shall (i) provide for the payment of drafts presented for,
on or thereunder by the beneficiary in accordance with the terms thereof, when
such drafts are accompanied by the documents (if any) described in the Letter of
Credit and (ii) to the extent not inconsistent with the terms hereof or any
applicable Letter of Credit Agreement, be subject to the Rules on International
Standby Practices (ISP98) (January 1999) (together with any subsequent revision
thereof approved by a Congress of the International Chamber of Commerce and
adhered to by the Issuing Bank, the "ISP", and shall, as to matters not governed
by the ISP, be governed by, and construed and interpreted in accordance with,
the laws of the State of Texas.

         (c) The Borrower agrees to pay to the Administrative Agent for the
account of each Lender, concurrently with the issuance of such Letter of Credit
and on each Quarterly Date thereafter, a nonrefundable letter of credit fee with
respect to each Letter of Credit issued in an

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 40
<PAGE>
amount equal to (i) the Applicable Margin for Eurodollar Loans, calculated in
accordance with the definition of "Applicable Margin" contained herein,
multiplied by (ii) the face amount of the Letter of Credit then in effect. The
Administrative Agent agrees to pay to each Lender, promptly after receiving any
payment of such letter of credit fees, such Lender's Commitment Percentage of
such fees. In addition, the Borrower agrees to pay to the Issuing Bank for its
own account, concurrently with the issuance of such Letter of Credit and on each
Quarterly Date thereafter, a nonrefundable fronting fee with respect to each
Letter of Credit issued by the Issuing Bank in an amount equal to one-eighth of
one percent (0.125%) per annum of the face amount of the Letter of Credit then
in effect. In addition to the foregoing fees, the Borrower shall pay or
reimburse the Issuing Bank for such normal and customary costs and expenses,
including, without limitation, administrative, issuance, amendment, payment and
negotiation charges, as are incurred or charged by the Issuing Bank in issuing,
effecting payment under, amending or otherwise administering any Letter of
Credit.

         (d) Upon receipt from the beneficiary of any Letter of Credit of any
demand for payment or other drawing under such Letter of Credit, the Issuing
Bank shall promptly notify the Borrower and each Lender as to the amount to be
paid as a result of such demand or drawing and the respective payment date. If
at any time the Issuing Bank shall make a payment to a beneficiary of a Letter
of Credit pursuant to a drawing under such Letter of Credit, each Lender will
pay to the Issuing Bank, immediately upon the Issuing Bank's demand at any time
commencing after such payment until reimbursement therefor in full by the
Borrower, an amount equal to such Lender's Commitment Percentage of such
payment, together with interest on such amount for each day from the date of
such demand to the date of payment by such Lender of such amount at a rate of
interest per annum equal to the Federal Funds Rate.

         (e) The Borrower shall be irrevocably and unconditionally obligated to
immediately reimburse the Issuing Bank for any amounts paid by the Issuing Bank
upon any drawing under any Letter of Credit, without presentment, demand,
protest or other formalities of any kind. The Issuing Bank will pay to each
Lender such Lender's Commitment Percentage of all amounts received from or on
behalf of the Borrower for application in payment, in whole or in part, of the
Reimbursement Obligation in respect of any Letter of Credit, but only to the
extent such Lender has made payment to the Issuing Bank in respect of such
Letter of Credit pursuant to subsection (d) above. Outstanding Reimbursement
Obligations shall bear interest at the Default Rate and such interest shall be
payable on demand.

         (f) The Reimbursement Obligations of the Borrower under this Agreement
and the other Loan Documents shall be absolute, unconditional and irrevocable,
and shall be performed strictly in accordance with the terms of this Agreement
and the other Loan Documents under all circumstances whatsoever, including,
without limitation, the following circumstances:

                  (i)      Any lack of validity or enforceability of any Letter
                           of Credit or any other Loan Document;

                  (ii)     Any amendment or waiver of or any consent to
                           departure from any Loan Document;

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 41
<PAGE>
                  (iii)    The existence of any claim, setoff, counterclaim,
                           defense or other right which any Loan Party or other
                           Person may have at any time against any beneficiary
                           of any Letter of Credit, the Administrative Agent,
                           the Issuing Bank, the Lenders or any other Person,
                           whether in connection with this Agreement or any
                           other Loan Document or any unrelated transaction;

                  (iv)     Any statement, draft or other document presented
                           under any Letter of Credit proving to be forged,
                           fraudulent, invalid or insufficient in any respect or
                           any statement therein being untrue or inaccurate in
                           any respect whatsoever;

                  (v)      Payment by the Issuing Bank under any Letter of
                           Credit against presentation of a draft or other
                           document that does not comply with the terms of such
                           Letter of Credit, provided, that such payment shall
                           not have constituted gross negligence or willful
                           misconduct of the Issuing Bank; and

                  (vi)     Any other circumstance whatsoever, whether or not
                           similar to any of the foregoing, provided that such
                           other circumstance or event shall not have been the
                           result of the gross negligence or willful misconduct
                           of the Issuing Bank.

         (g) The Borrower assumes all risks of the acts or omissions of any
beneficiary of any Letter of Credit with respect to its use of such Letter of
Credit. Neither the Administrative Agent, the Issuing Bank, the Lenders nor any
of their respective officers or directors shall have any responsibility or
liability to the Borrower or any other Person for: (i) the failure of any draft
to bear any reference or adequate reference to any Letter of Credit, or the
failure of any documents to accompany any draft at negotiation, or the failure
of any Person to surrender or to take up any Letter of Credit or to send
documents apart from drafts as required by the terms of any Letter of Credit, or
the failure of any Person to note the amount of any instrument on any Letter of
Credit, (ii) errors, omissions, interruptions or delays in transmission or
delivery of any messages, (iii) the validity, sufficiency or genuineness of any
draft or other document, or any endorsement(s) thereon, even if any such draft,
document or endorsement should in fact prove to be in any and all respects
invalid, insufficient, fraudulent or forged or any statement therein is untrue
or inaccurate in any respect, (iv) the payment by the Issuing Bank to the
beneficiary of any Letter of Credit against presentation of any draft or other
document that does not comply with the terms of the Letter of Credit, or (v) any
other circumstance whatsoever in making or failing to make any payment under a
Letter of Credit; provided, however, that, notwithstanding the foregoing, the
Borrower shall have a claim against the Issuing Bank, and the Issuing Bank shall
be liable to the Borrower, to the extent of any direct, but not indirect or
consequential, damages suffered by the Borrower which the Borrower proves in a
final nonappealable judgment were caused by (A) the Issuing Bank's willful
misconduct or gross negligence in determining whether documents presented under
any Letter of Credit complied with the terms thereof or (B) the Issuing Bank's
willful failure to pay under any Letter of Credit after presentation to it of
documents strictly complying with the terms and conditions of such Letter of
Credit. The Issuing Bank may accept documents that appear on their face to be in
order, without responsibility for further investigation, regardless of any
notice or information to the contrary.

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 42

         (h) All Letters of Credit issued pursuant to the Original Agreement,
the First Restated Agreement or the Existing Agreement which are outstanding as

this Agreement, which outstanding Letters of Credit are set forth in Schedule
2.13.

         Section 2.14 Mandatory Prepayments.

         (a) Prepayments resulting from Overadvances. If at any time the sum of
the aggregate outstanding principal amount of the Revolving Loan Portion of the
Loans plus the Letter of Credit Liabilities exceeds an amount equal to the
lesser of (i) the Borrowing Base or (ii) the aggregate amount of the Commitments
in effect at such time, within one Business Day immediately after each
occurrence thereof the Borrower shall pay to the Administrative Agent the amount
of such excess as a prepayment of the Revolving Loan Portion of the Loans.

         (b) Prepayments from Excess Cash Flow. The Borrower shall, on or before
October 31st of each year during the term of this Agreement, pay (or cause to be
paid) to the Administrative Agent, as a prepayment of the Loans and other
Obligations then outstanding, an aggregate amount equal to fifty percent (50%)
of the Excess Cash Flow for the fiscal year ended on the July 31st immediately
preceding such payment date; provided, however, that, for purposes of this
Section 2.1(b), Excess Cash Flow attributable to the Canadian Subsidiaries
generated on and after the Closing Date shall not exceed $2,000,000 in the
aggregate.

         (c) Prepayments from Asset Dispositions. The Borrower shall, within
five days of the receipt of any Net Proceeds related to an Asset Disposition,
prepay the outstanding Loans as of such date in an aggregate amount equal to the
Net Proceeds of such Asset Disposition. For purposes of this Section 2.14, the
following terms shall have the following meanings:

         (i)      "Asset Disposition" means the disposition, whether by sale,
                  lease, transfer, loss, damage, destruction, condemnation or
                  otherwise, of any assets of the Borrower or any of its
                  Subsidiaries other than sales of assets permitted under
                  Section 9.8; and

         (ii)     "Net Proceeds" means cash proceeds (including casualty
                  insurance proceeds paid with respect to damage to property)
                  received by the Borrower or any of its Subsidiaries from any
                  Asset Disposition (including payments under notes or other
                  debt securities received in connection with any Asset
                  Disposition and insurance proceeds and awards of
                  condemnation), net of (A) the costs of such sale, lease,
                  transfer or other disposition (including professional fees and
                  expenses and taxes attributable to such sale, lease or
                  transfer which are actually paid or required to be paid) and
                  (B) amounts applied to repayment of Debt (other than the
                  Obligations) secured by a Lien on the asset subject to such
                  disposition.

         (d) Prepayments from Securities Offerings. In the event that the
Borrower or any of its Subsidiaries issues any Securities (as defined below), no
later than the third (3rd) Business Day following the date of receipt of any
proceeds from any such issuance, the Borrower shall

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 43
<PAGE>
prepay the outstanding Loans in an amount equal to all proceeds of such
issuance, net of underwriting discounts and commissions and other reasonable
costs associated therewith. "Securities" means any stock, shares, options,
warrants, voting trust certificates or other instruments evidencing an ownership
interest, or a right to acquire an ownership interest, in a Person or any bonds,
debentures, notes or other evidences of indebtedness, secured or unsecured;
provided, however, that, for purposes of this Section 2.14(d), the term
"Securities" shall not include any evidence of Debt permitted to be incurred
under clause (a), (c), (d), (e) or (f) of Section 9.1.

         (e) Application of Prepayments. Each prepayment under this Section 2.14
shall be accompanied by the prepayment of accrued and unpaid interest on the
amount prepaid to the date of prepayment and any amounts payable under Section
4.5(a) and shall be applied first to the installments of principal due under the
Amortizing Loan Portion of the Loans in the inverse order of the maturities of
such installments and thereafter to the outstanding principal of the Revolving
Loan Portion of the Loans.

                                    Payments

         Section 3.1 Method of Payment. All payments of principal, interest,
fees and other amounts to be made by the Borrower under this Agreement and the
other Loan Documents shall be made to the Administrative Agent at the Principal
Office for the account of each Lender's Applicable Lending Office in Dollars and
in immediately available funds, without setoff, deduction or counterclaim, not
later than 11:00 a.m. (Dallas, Texas time) on the date on which such payment
shall become due (each such payment made after such time on such due date to be
deemed to have been made on the next succeeding Business Day). The Borrower
shall, at the time of making each such payment, specify to the Administrative
Agent the sums payable by the Borrower under this Agreement and the other Loan
Documents to which such payment is to be applied (and in the event that the
Borrower fails to so specify, or if an Event of Default has occurred and is
continuing, the Administrative Agent may apply such payment to the Obligations
in such order and manner as the Administrative Agent may elect, subject to
Section 3.2). Upon the occurrence and during the continuation of an Event of
Default, all proceeds of any Collateral, all funds from time to time on deposit
in any Concentration Account or any collection account referred to in Section
8.13 and all other funds of the Borrower or any Guarantor in the possession of
the Administrative Agent or any Lender, may be applied by the Administrative
Agent to the Obligations in such order and manner as the Administrative Agent
may elect, subject to Section 3.2. Each payment received by the Administrative
Agent under this Agreement or any other Loan Document for the account of a
Lender shall be paid promptly to such Lender, in immediately available funds,
for the account of such Lender's Applicable Lending Office. Whenever any payment
under this Agreement or any other Loan Document shall be stated to be due on a
day that is not a Business Day, such payment may be made on the next succeeding
Business Day, and such extension of time shall in such case be included in the
computation of the payment of interest and commitment fee, as the case may be.

         Section 3.2 Pro Rata Treatment. Except to the extent otherwise provided
in this Agreement: (a) each Loan shall be made by the Lenders under Section 2.1,
each payment of commitment fees under Section 2.10(a) shall be made for the
account of the Lenders, and each termination or reduction of the Commitments
under Section 2.12 shall be applied to the Commitments of the Lenders, pro rata
according to the respective unused Commitments; (b) the making of Loans of a
particular Type shall be made pro rata among the Lenders holding Loans of such
Type according to the amounts of their respective Commitments, and the
Conversion and Continuation of Loans of a particular Type (other than
Conversions provided for by Section 4.4) shall be made among the Lenders holding
Loans of such Type pro rata in accordance with the respective unpaid principal
amounts of such Loans held by such Lenders; (c) each payment and prepayment by
the Borrower of principal of or interest on (i) Loans of a particular Type shall
be made to the Administrative Agent for the account of the Lenders holding Loans
of such Type pro rata in accordance with the respective unpaid principal amounts
of such Loans held by such Lenders, (ii) Loans constituting the Revolving Loan
Portion shall be made to the Administrative Agent for the account of the Lenders
holding such Loans pro rata in accordance with their Commitment Percentages, and
(iii) Loans constituting the Amortizing Loan Portion shall be made to the
Administrative Agent for the account of the Lenders holding such Loans pro rata
in accordance with their Amortizing Loan Portion Percentages; (d) Interest
Periods for Loans of a particular Type shall be allocated among the Lenders
holding Loans of such Type pro rata according to the respective principal
amounts held by such Lenders; and (e) the Lenders (other than the Issuing Bank)
shall purchase participations in the Letters of Credit pro rata in accordance
with their Commitment Percentages. The principal amount of the Revolving Loan
Portion and the Amortizing Loan Portion of the Loans outstanding as of the
Closing Date shall be allocated to and held by the Lenders pro rata based upon
the respective amounts of their Commitments.

         Section 3.3 Sharing of Payments, Etc. If a Lender shall obtain payment
of any principal of or interest on any of the Obligations due to such Lender
hereunder through the exercise of any right of setoff, banker's lien,
counterclaim or similar right, or otherwise, it shall promptly purchase from the
other Lenders participations in the Obligations held by the other Lenders in
such amounts, and make such adjustments from time to time, as shall be equitable
to the end that all the Lenders shall share pro rata in accordance with the
unpaid principal and interest on the Obligations then due to each of them. To
such end, all of the Lenders shall make appropriate adjustments among themselves
(by the resale of participations sold or otherwise) if all or any portion of
such excess payment is thereafter rescinded or must otherwise be restored. Each
of the Borrower and each other Loan Party agrees, to the fullest extent it may
effectively do so under applicable law, that any Lender so purchasing a
participation in the Obligations by the other Lenders may exercise all rights of
setoff, banker's lien, counterclaim or similar rights with respect to such
participation as fully as if such Lender were a direct holder of Obligations in
the amount of such participation. Nothing contained herein shall require any
Lender to exercise any such right or shall affect the right of any Lender to
exercise, and retain the benefits of exercising, any such right with respect to
any other indebtedness, liability or obligation of the Borrower or any other
Loan Party.

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 45

         Section 3.4 Non-Receipt of Funds by the Administrative Agent. Unless
the Administrative Agent shall have been notified by a Lender or the Borrower
(the "Payor") prior to the date on which such Lender is to make payment to the
Administrative Agent of the proceeds of a Loan to be made by it hereunder or the
Borrower is to make a payment to the Administrative Agent for the account of one
or more of the Lenders, as the case may be (such payment being herein called the
"Required Payment"), which notice shall be effective upon receipt, that the
Payor does not intend to make the Required Payment to the Administrative Agent,
the Administrative Agent may assume that the Required Payment has been made and
may, in reliance upon such assumption (but shall not be required to), make the
amount thereof available to the intended recipient on such date and, if the
Payor has not in fact made the Required Payment to the Administrative Agent, the
recipient of such payment shall, on demand, pay to the Administrative Agent the
amount made available to it together with interest thereon in respect of the
period commencing on the date such amount was so made available by the
Administrative Agent until the date the Administrative Agent recovers such
amount at a rate per annum equal to the Federal Funds Rate for such period.

         Section 3.5 Taxes. (a) All payments by the Borrower of principal of and
interest on the Loans and the Letter of Credit Liabilities and of all fees and
other amounts payable under the Loan Documents shall be made free and clear of,
and without withholding or deduction by reason of, any present or future
Indemnified Taxes or Other Taxes. If any Indemnified Taxes or Other Taxes are so
levied or imposed, the Borrower will (i) make additional payments in such
amounts so that every net payment of principal of and interest on the Loans and
the Letter of Credit Liabilities and of all other amounts payable by it under
the Loan Documents, after withholding or deduction for or on account of any
Indemnified Taxes or Other Taxes (including any tax imposed on or measured by
net income of a Lender attributable to payments made to or on behalf of a Lender
pursuant to this Section 3.5 and any penalties or interest attributable to such
payments), will not be less than the amount provided for herein or therein
absent such withholding or deduction (provided that the Borrower shall not have
any obligation to pay such additional amounts to any Lender to the extent that
such Indemnified Taxes or Other Taxes are levied or imposed by reason of the
failure of such Lender to comply with the provisions of Section 3.6), (ii) make
such withholding or deduction and (iii) remit the full amount deducted or
withheld to the relevant Governmental Authority in accordance with applicable
law. Without limiting the generality of the foregoing, the Borrower will, upon
written request of any Lender, reimburse each such Lender for the amount of (A)
Indemnified Taxes or Other Taxes levied or imposed by any Governmental Authority
and paid by such Lender as a result of payments made by the Borrower under or
with respect to the Loans other than Indemnified Taxes or Other Taxes previously
withheld or deducted by the Borrower which have previously resulted in the
payment of the required additional amount to such Lender, and (B) Indemnified
Taxes or Other Taxes levied or imposed with respect to any Lender reimbursement
under the foregoing clause (A), so that the net amount received by such Lender
(net of payments made under or with respect to the Loans and the Letter of
Credit Liabilities) after such reimbursement will not be less than the net
amount such Lender would have received if such Indemnified Taxes or Other Taxes
on such reimbursement had not been levied or imposed. The Borrower shall furnish
promptly to the Administrative Agent for distribution to each affected Lender,
as the case may be, upon request of such Lender, official receipts evidencing
any such payment, withholding or reduction.

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 46
<PAGE>
      (b)   The Borrower will indemnify the Administrative Agent and each Lender
(without duplication) against, and reimburse the Administrative Agent and each
Lender for, all present and future Indemnified Taxes or Other Taxes (including
interest and penalties) levied or collected (whether or not legally or correctly
imposed, assessed, levied or collected). Any such indemnification shall be on an
after-tax basis, taking into account any such Indemnified Taxes or Other Taxes
imposed on the amounts paid as indemnity.

      (c)   Without prejudice to the survival of any other term or provision of
this Agreement, the obligations of the Borrower under this Section 3.5 shall
survive the payment of the Loans and the other Obligations and termination of
the Commitments.

      Section 3.6    Withholding Tax Exemption. Each Lender or holder of a
participation interest in the Loans or Commitments permitted pursuant to Section
13.8(a) (a "Participant") that is not incorporated or otherwise formed under the
laws of the U.S. or a state thereof (a "Non-U.S. Lender") agrees that it will,
prior to or on or about the Closing Date or the date upon which it initially
becomes a party to this Agreement and if it is legally able to do so, deliver to
the Borrower and the Administrative Agent (or, in the case of a Participant, on
or before the date such Participant purchases its related participation), two
duly completed copies of U.S. Internal Revenue Service Form W-8ECI or W-8BEN or,
in the case of a Non-U.S. Lender claiming exemption from U.S. federal
withholding tax under Section 871(h) or 881(c) of the Code with respect to
payments of "portfolio interest", a statement substantially in the form of
Exhibit H hereto, appropriately completed, and a Form W-8BEN, or other
equivalent successor form, as appropriate, certifying in any case that such
Lender is entitled to receive payments from the Borrower under any Loan Document
without deduction or withholding of any U.S. federal income taxes. Each Lender
which so delivers a Form W-8ECI or W-8BEN or other equivalent successor form, as
appropriate, further undertakes to deliver to the Borrower and the
Administrative Agent two additional copies of such form (or a successor form) on
or before the date such form expires or becomes obsolete or after the occurrence
of any event requiring a change in the most recent form so delivered by it, and
such amendments thereto or extensions or renewals thereof as may be reasonably
requested by the Borrower or the Administrative Agent, in each case certifying
that such Lender is entitled to receive payments from the Borrower under any
Loan Document without deduction or withholding of any U.S. federal income taxes,
unless an event (including without limitation any change in treaty, law or
regulation) has occurred prior to the date on which any such delivery would
otherwise be required which renders all such forms inapplicable or which would
prevent such Lender from duly completing and delivering any such form with
respect to it and such Lender advises the Borrower and the Administrative Agent
that it is not capable of receiving such payments without any deduction or
withholding of U.S. federal income tax.

      Section 3.7    Reinstatement of Obligations. Notwithstanding anything to
the contrary contained in this Agreement or any other Loan Document, if the
payment of any amount of principal of or interest with respect to the Loans, the
Reimbursement Obligations or any other amount of the Obligations, or any portion
thereof, is rescinded, voided or must otherwise be refunded by the
Administrative Agent, any Lender or the Issuing Bank upon the insolvency,
bankruptcy or reorganization of the Borrower or any other Loan Party or
otherwise for any

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 47
<PAGE>
reason whatsoever, then each of (a) the Obligations, (b) the Loan Documents
(including, without limitation, this Agreement, the Notes and the Security
Documents), (c) the indebtedness, liabilities and obligations of the Borrower
and any other Loan Party under the Loan Documents and (d) all Liens for the
benefit of the Administrative Agent and the Lenders created under or evidenced
by the Loan Documents, will be automatically reinstated and become automatically
effective and in full force and effect, all to the extent that and as though
such payment so rescinded, voided or otherwise refunded had never been made.

                         Yield Protection and Illegality

      Section 4.1    Additional Costs.

      (a)   The Borrower shall pay directly to each Lender from time to time,
promptly upon the request of such Lender, the costs incurred by such Lender
which such Lender determines are attributable to its making or maintaining of
any Eurodollar Loans or its obligation to make any of such Loans, or any
reduction in any amount receivable by such Lender hereunder in respect of any
such Loans or obligations (such increases in costs and reductions in amounts
receivable being herein called "Additional Costs"), resulting from any
Regulatory Change which:

      (i)   changes the basis of taxation of any amounts payable to such Lender
            under this Agreement or its Notes in respect of any of such Loans
            (other than Excluded Taxes and Indemnified Taxes which are subject
            to Section 3.5);

      (ii)  imposes or modifies any reserve, special deposit, minimum capital,
            capital ratio or similar requirement relating to any extensions of
            credit or other assets of, or any deposits with or other liabilities
            or commitments of, such Lender (including any of such Loans or any
            deposits referred to in the definition of "Eurodollar Rate" in
            Section 1.1 hereof, but excluding the Reserve Requirement to the
            extent it is included in the calculation of the Adjusted Eurodollar
            Rate); or

      (iii) imposes any other condition affecting this Agreement or the Notes or
            any of such extensions of credit or liabilities or commitments
            contemplated hereunder or thereunder.

Each Lender will notify the Borrower (with a copy to the Administrative Agent)
of any event occurring after the Closing Date which will entitle such Lender to
compensation pursuant to this Section 4.1(a) as promptly as practicable after it
obtains knowledge thereof and determines to request such compensation, and (if
so requested by the Borrower) will designate a different Applicable Lending
Office for the Eurodollar Loans of such Lender if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
sole opinion of such Lender, violate any law, rule or regulation or be in any
way disadvantageous to such Lender, provided that such Lender shall have no
obligation to so designate an Applicable Lending Office located in the U.S. Each
Lender will furnish the Borrower with a certificate

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 48
<PAGE>
setting forth the basis and the amount of each request of such Lender for
compensation under this Section 4.1(a). If any Lender requests compensation from
the Borrower under this Section 4.1(a), the Borrower may, by notice to such
Lender (with a copy to the Administrative Agent), suspend the obligation of such
Lender to make or Continue making, or Convert ABR Loans into, Eurodollar Loans
until the Regulatory Change giving rise to such request ceases to be in effect
(in which case the provisions of Section 4.4 hereof shall be applicable).

      (b)   Without limiting the effect of the foregoing provisions of this
Section 4.1, in the event that, by reason of any Regulatory Change, any Lender
either (i) incurs Additional Costs based on or measured by the excess above a
specified level of the amount of a category of deposits or other liabilities of
such Lender which includes deposits by reference to which the interest rate on
Eurodollar Loans is determined as provided in this Agreement or a category of
extensions of credit or other assets of such Lender which includes Eurodollar
Loans or (ii) becomes subject to restrictions on the amount of such a category
of liabilities or assets which it may hold, then, if such Lender so elects by
notice to the Borrower (with a copy to the Administrative Agent), the obligation
of such Lender to make or Continue making, or Convert ABR Loans into, Eurodollar
Loans hereunder shall be suspended until such Regulatory Change ceases to be in
effect (in which case the provisions of Section 4.4 hereof shall be applicable).

      (c)   Determinations and allocations by any Lender for purposes of this
Section 4.1 of the effect of any Regulatory Change on its costs of maintaining
its obligation to make Loans or of making or maintaining Loans or on amounts
receivable by it in respect of Loans, and of the additional amounts required to
compensate such Lender in respect of any Additional Costs, shall be conclusive
in the absence of manifest error, provided that such determinations and
allocations are made on a reasonable basis.

      Section 4.2    Limitation on Types of Loans. Anything herein to the
contrary notwithstanding, if with respect to any Eurodollar Loans for any
Interest Period therefor:

      (a)   the Administrative Agent determines (which determination shall be
conclusive absent manifest error) that quotations of interest rates for the
relevant deposits referred to in the definition of "Eurodollar Rate" in Section
1.1 hereof are not being provided in the relative amounts or for the relative
maturities for purposes of determining the rate of interest for such Loans as
provided in this Agreement; or

      (b)   the Required Lenders determine (which determination shall be
conclusive absent manifest error) and notify the Administrative Agent that the
relevant rates of interest referred to in the definition of "Eurodollar Rate" or
"Adjusted Eurodollar Rate" in Section 1.1 hereof on the basis of which the rate
of interest for such Loans for such Interest Period is to be determined do not
accurately reflect the cost to the Lenders of making or maintaining such Loans
for such Interest Period;

then the Administrative Agent shall give the Borrower prompt notice thereof and,
so long as such condition remains in effect, the Lenders shall be under no
obligation to make Eurodollar Loans or to Convert ABR Loans into Eurodollar
Loans and the Borrower shall, on the last day(s) of the

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 49
<PAGE>
then current Interest Period(s) for the outstanding Eurodollar Loans, either
prepay such Loans or Convert such Loans into ABR Loans in accordance with the
terms of this Agreement.

      Section 4.3    Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to (a) honor its obligation to make Eurodollar Loans
or (b) maintain Eurodollar Loans, then such Lender shall promptly notify the
Borrower (with a copy to the Administrative Agent) thereof and such Lender's
obligation to make or maintain Eurodollar Loans and to Convert ABR Loans into
Eurodollar Loans hereunder shall be suspended until such time as such Lender may
again make and maintain Eurodollar Loans (in which case the provisions of
Section 4.4 hereof shall be applicable).

      Section 4.4    Treatment of Affected Loans. If the obligation of any
Lender to make or Continue, or to Convert ABR Loans into, Eurodollar Loans is
suspended pursuant to Section 4.1 or 4.3 hereof, such Lender's Eurodollar Loans
shall be automatically Converted into ABR Loans on the last day(s) of the then
current Interest Period(s) for the Eurodollar Loans (or, in the case of a
Conversion required by Section 4.1(b) or 4.3 hereof, on such earlier date as
such Lender may specify to the Borrower with a copy to the Administrative Agent)
and, unless and until such Lender gives notice as provided below that the
circumstances specified in Section 4.1 or 4.3 hereof which gave rise to such
Conversion no longer exist:

      (a)   to the extent that such Lender's Eurodollar Loans have been so
Converted, all payments and prepayments of principal which would otherwise be
applied to such Lender's Eurodollar Loans shall be applied instead to its ABR
Loans; and

      (b)   all Loans which would otherwise be made or Continued by such Lender
as Eurodollar Loans shall be made as or Converted into ABR Loans and all Loans
of such Lender which would otherwise be Converted into Eurodollar Loans shall be
Converted instead into (or shall remain as) ABR Loans.

If such Lender gives notice to the Borrower that the circumstances specified in
Section 4.1 or 4.3 hereof which gave rise to the Conversion of such Lender's
Eurodollar Loans pursuant to this Section 4.4 no longer exist (which such Lender
agrees to do promptly upon such circumstances ceasing to exist) at a time when
Eurodollar Loans are outstanding, such Lender's ABR Loans shall be automatically
Converted, on the first day(s) of the next succeeding Interest Period(s) for
such outstanding Eurodollar Loans, to the extent necessary so that, after giving
effect thereto, all Loans held by the Lenders holding Eurodollar Loans and by
such Lender are held pro rata (as to principal amounts, Types and Interest
Periods) in accordance with their respective Commitments.

      Section 4.5    Compensation. The Borrower shall pay to the Administrative
Agent for the account of each Lender, promptly upon the request of such Lender
through the Administrative Agent, such amount or amounts as shall be sufficient
(in the reasonable opinion of such Lender) to compensate it for any loss, cost
or expense incurred by it as a result of:

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 50
<PAGE>
      (a)   Any payment, prepayment or Conversion of a Eurodollar Loan for any
reason (including, without limitation, the acceleration of the outstanding Loans
pursuant to Section 11.2) on a date other than the last day of an Interest
Period for such Loan; or

      (b)   Any failure by the Borrower for any reason (including, without
limitation, the failure of any conditions precedent specified in Article 6 to be
satisfied) to borrow, Convert or prepay a Eurodollar Loan on the date for such
borrowing, Conversion or prepayment specified in the relevant notice of
borrowing, prepayment or Conversion under this Agreement.

      Section 4.6    Capital Adequacy. If, after the Closing Date, any Lender
shall have determined that the adoption or implementation of any applicable law,
rule or regulation regarding capital adequacy (including, without limitation,
any law, rule or regulation implementing the Basle Accord), or any change
therein, or any change in the interpretation or administration thereof by any
central bank or other Governmental Authority charged with the interpretation or
administration thereof, or compliance by such Lender (or its parent) with any
guideline, request or directive regarding capital adequacy (whether or not
having the force of law) of any central bank or other Governmental Authority
(including, without limitation, any guideline or other requirement implementing
the Basle Accord), has or would have the effect of reducing the rate of return
on such Lender's (or its parent's) capital as a consequence of its obligations
hereunder or the transactions contemplated hereby to a level below that which
such Lender (or its parent) could have achieved but for such adoption,
implementation, change or compliance (taking into consideration such Lender's
policies with respect to capital adequacy) by an amount deemed by such Lender to
be material, then from time to time, within ten Business Days after demand by
such Lender (with a copy to the Administrative Agent), the Borrower shall pay to
such Lender such additional amount or amounts as will compensate such Lender (or
its parent) for such reduction. A certificate of such Lender claiming
compensation under this Section 4.6 and setting forth the additional amount or
amounts to be paid to it hereunder shall be conclusive absent manifest error,
provided that the determination thereof is made on a reasonable basis. In
determining such amount or amounts, such Lender may use any reasonable averaging
and attribution methods.

      Section 4.7    Additional Interest on Eurodollar Loans. The Borrower shall
pay, directly to each Lender from time to time, additional interest on the
unpaid principal amount of each Eurodollar Loan held by such Lender, from the
date of the making of such Eurodollar Loan until such principal amount is paid
in full, at an interest rate per annum determined by such Lender in good faith
equal to the positive remainder (if any) of (a) the Adjusted Eurodollar Rate
applicable to such Eurodollar Loan minus (b) the Eurodollar Rate applicable to
such Eurodollar Loan. Each payment of additional interest pursuant to this
Section 4.7 shall be payable by the Borrower on each date upon which interest is
payable on such Eurodollar Loan pursuant to Section 2.4(b); provided, however,
that the Borrower shall not be obligated to make any such payment of additional
interest until the first Business Day after the date when the Borrower has been
informed (i) that such Lender is subject to a Reserve Requirement and (ii) of
the amount of such Reserve Requirement (after which time the Borrower shall be
obligated to make all such payments of additional interest, including, without
limitation, such payment of additional interest

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 51
<PAGE>
that otherwise would have been payable by the Borrower on or prior to such time
had the Borrower been earlier informed).

                                   ARTICLE 5

                                   Security

      Section 5.1    Collateral. Subject to Section 5.8 hereof, to secure the
full and complete payment and performance of the Obligations, the Borrower
shall, and shall cause each of its Subsidiaries to, on or before the Closing
Date, grant to the Administrative Agent for the benefit of the Administrative
Agent and the Lenders a perfected, first priority Lien (except for Permitted
Liens, if any, which are expressly permitted by the Loan Documents to have
priority over the Liens in favor of the Administrative Agent) on all of its
right, title and interest in and to the following Property, whether now owned or
hereafter acquired, pursuant to the Security Documents:

      (a)   all Capital Stock of each of the Subsidiaries of the Borrower

      (b)   all other Property of the Borrower and each of its Subsidiaries

from all parties to such contracts to permit the grant of a security interest
therein to the Administrative Agent as security for the payment and performance
of the Obligations and assignment of such contracts); goods;
health-care-insurance receivables; instruments (including, without limitation,
certificates of deposit, negotiable instruments, notes and drafts); inventory;

limitation, cash proceeds, non-cash proceeds and proceeds of letters of credit);

immaterial leases of real property (provided, however, that the Administrative
Agent's Lien on certificated vehicles shall not be required to be perfected

Unless otherwise agreed by the Administrative Agent and the Required Lenders,
the pledge of the Capital Stock of any Canadian Subsidiary shall be
appropriately registered in the share

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 52
<PAGE>
registry of such Canadian Subsidiary. The Borrower covenants that none of the
Capital Stock to be pledged in accordance with this Section 5.1 shall be subject
to any transfer restrictions, shareholders' agreement or other restriction
except for such restrictions under applicable securities laws and such
restrictions, if any, as may be reasonably acceptable to the Administrative
Agent. In connection with and in addition to the foregoing, the Borrower and its
Subsidiaries shall execute and/or deliver such further agreements, documents and
instruments (including, without limitation, stock certificates, stock powers and
financing statements) as the Administrative Agent may reasonably request in
order for it to obtain and maintain the perfected, first priority Liens to be
granted in accordance with this Section 5.1.

      Section 5.2    Guaranties. Subject to Section 5.8 hereof, each Subsidiary
of the Borrower in existence on the Closing Date shall guarantee the payment and

to Section 5.8 hereof, contemporaneously with the creation or acquisition of any
Subsidiary of the Borrower after the Closing Date, the Borrower shall, and shall

benefit of the Administrative Agent and the Lenders, a perfected, first priority
security interest in all Capital Stock or other ownership interests in or

none of the Capital Stock to be pledged in accordance with this Section 5.3

Closing Date) or contemporaneously with the acquisition of any fee real Property
or leasehold or other interest therein (with respect to any fee real Property or
leasehold or other interest therein acquired after the Closing Date), execute,

and its counsel, including, without limitation, if requested by the
Administrative Agent, a commitment for a mortgagee policy of title insurance or
a title opinion in favor of the Administrative Agent, in form and substance
reasonably satisfactory to the Administrative Agent, that the Mortgage creates a
valid, first priority Lien on the fee estate or leasehold estate or other
interest (as applicable) in favor of the Administrative Agent for the benefit of
the Administrative Agent and the Lenders (except for Permitted Liens, if any,
which are expressly permitted by the Loan Documents to have priority over the
Liens in favor of the Administrative Agent), together with appraisals and
surveys if requested by the Administrative Agent; provided, however, that, with
respect to any fee real Property or any leasehold or other interest therein
having a fair market value of less than $100,000, the Borrower and such
Subsidiaries shall not be required to execute, acknowledge or deliver such
documents unless or until fee, leasehold or other real Property or Properties
having an aggregate fair market value of $100,000 or more would be covered by
any such new Mortgage or amendment or modification to an existing Mortgage. In
addition, subject to Section 5.8 hereof, if requested by the Administrative
Agent, the Borrower shall, and shall cause each of its Subsidiaries with an
interest in such Properties to, (i) deliver or cause to be delivered to the
Administrative Agent, a mortgagee policy of title insurance insuring the Liens
of the Mortgage covering such real Property in an amount reasonably satisfactory

priority over the Liens in favor of the Administrative Agent) or, with respect
to such Properties located in Canada, title opinions in form and substance
reasonably satisfactory to the Administrative Agent issued by law firms

      (b)   With respect to each lease of real Property executed or obtained by
the Borrower or any Subsidiary of the Borrower, the Borrower shall obtain
waivers or subordinations of all landlord's and similar Liens (whether created
or existing by contract, statute or otherwise) from each lessor and other
agreements from such lessor and its lenders necessary or appropriate to ensure
the Administrative Agent's perfected, first priority Lien on the Collateral or
Property affected thereby, the Administrative Agent's access to such Collateral
or Property and the right of the Administrative Agent, the Lenders or their
designees to succeed to the rights of such Loan Party that is the lessee under
the lease, in each case in form and substance reasonably satisfactory to the
Administrative Agent; provided, however, that such waivers or subordinations
need not be obtained for individual leases where inventory or equipment of a
Loan Party having an aggregate fair market value of less than $50,000 is
located; provided, further, however, that not more than $100,000 of inventory or
equipment in the aggregate shall be located on leaseholds or easements for which
waivers or subordinations have not been obtained.

      (c)   The Loan Parties will cause any carrier, warehouseman, mechanic,
materialman, repairman, landlord, owner, bailee or other similar Person in
possession of inventory or equipment of a Loan Party having an aggregate fair
market value of $50,000 or more to execute a written agreement, in form and
substance reasonably satisfactory to the Administrative Agent, waiving or
subordinating any Liens on such inventory or equipment; provided, however, that
the Loan Parties will only be required to use commercially reasonable efforts to
obtain such a written agreement from landlords and their lenders (without the
giving of monetary consideration to the Persons providing such agreements as
consideration for such agreements).

      Section 5.5    Release of Collateral. Upon any sale, transfer or other
disposition of Collateral that is expressly permitted under Section 9.8 and upon
five Business Days prior written request by the Borrower, the Administrative
Agent shall execute at the Borrower's expense such documents as may be necessary
to evidence the release by the Administrative Agent of its Liens on such
Collateral being sold, transferred or otherwise disposed of; provided, however,
that (a) the Administrative Agent shall not be required to release any Lien on
any Collateral if a Default shall have occurred and be continuing, (b) the
Administrative Agent shall not be required to execute any such document on terms
which, in the Administrative Agent's opinion, would expose the Administrative
Agent to liability or create any obligation not reimbursed by the Borrower or
entail any consequences other than the release of such Lien without recourse or
warranty, and (c) such release shall not in any manner discharge, affect or
impair any of the Obligations or any of the Administrative Agent's Liens on any
Collateral retained by the Borrower or any of its Subsidiaries, including,
without limitation, its Liens on the proceeds of any such sale, transfer or
other disposition.

      Section 5.6    Setoff. If an Event of Default shall have occurred and be
continuing, each Lender is hereby authorized at any time and from time to time,
without notice to the Borrower or any other Person (any such notice being hereby
expressly waived by the Borrower and the Loan Parties), to set off and apply any
and all deposits (general or special, time or demand, provisional or final) at
any time held and other indebtedness at any time owing by such Lender to or for
the credit or the account of the Borrower or any other Loan Party against any
and all of the

Obligations of the Borrower or such other Loan Party now or hereafter existing
under this Agreement, any of such Lender's Notes or any other Loan Document,
irrespective of whether or not the Administrative Agent or such Lender shall
have made any demand under this Agreement, any of such Lender's Note or any such
other Loan Document and although such Obligations may be unmatured. Each Lender
agrees promptly to notify the Borrower (with a copy to the Administrative Agent)
after any such setoff and application, provided that the failure to give such
notice shall not affect the validity of such setoff and application. The rights
and remedies of each Lender hereunder are in addition to other rights and
remedies (including, without limitation, other rights of setoff) which such
Lender may have.

      Section 5.7    Further Assurances. The Borrower shall, and shall cause
each of the other Loan Parties and other appropriate Persons (as applicable) to,
promptly upon any such request, (a) execute and/or deliver such further
agreements, documents and instruments (including, without limitation, Security

request, provide such information regarding the Loan Parties and/or the
Collateral (including, without limitation, the specific descriptions thereof and

reasonably request from time to time in order for the Administrative Agent to
obtain and maintain valid, perfected, first priority Liens to be granted in
accordance with this Article 5.

Obligations, (b) none of the Canadian Subsidiaries shall be obligated to execute
a Guaranty guaranteeing payment or performance of the Obligations, and (c) none
of the Canadian Subsidiaries shall be obligated to execute a Security Agreement

contrary contained in clause (a), clause (b) or clause (c) of this Section 5.8
preceding or contained elsewhere in this Agreement or in any other Loan
Document, promptly upon (and, in any event, within ten Business Days after) any
written request therefor made by the Administrative Agent or the Required

Subsidiary will execute and/or deliver, or cause to be executed and/or
delivered, each of the Loan Documents required to be executed and/or delivered

preceding), including, without limitation, each of the following as may be so
requested and all of which shall be in form and substance satisfactory to the

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 77

      under such policy, but in any event in such amounts as are reasonably
      available as determined by the Borrower's independent insurance broker
      reasonably acceptable to the Administrative Agent.

      claims for bodily injury, death or Property damage occurring on, in or

Such insurance shall be written by financially responsible companies selected by
the Borrower and having an A.M. Best Rating of "A-" or better and being in a
financial size category of "VI" or larger, or by other companies reasonably
acceptable to the Administrative Agent. Each policy referred to in this Section
8.5 shall provide that it will not be canceled, amended or reduced except after
not less than 30 days' prior written notice to the Administrative Agent and
shall also provide that the interests of the Administrative Agent and the
Lenders shall not be invalidated or reduced by any act, omission or negligence
of the Borrower or any of its Subsidiaries. The Borrower will advise the
Administrative Agent promptly of any policy cancellation, reduction or
amendment. For purposes hereof, the term "Peril" shall mean, collectively, fire,
lightning, flood, windstorm, hail, explosion, riot and civil commotion,

reasonable notice to the Borrower, to examine, copy and make extracts from its
books and records, to visit and inspect its Properties and to discuss its
business, operations and financial condition with its officers and independent
certified public accountants. The Borrower will authorize its accountants in
writing (with a copy to the Administrative Agent) to comply with this Section
8.6. The Administrative Agent or its representatives may, at any time and from
time to time at the Borrower's expense, conduct field exams or other inspections

preparation of the financial statements referenced in Section 8.1 are hereafter
required or permitted by GAAP and are adopted by the Borrower or any of its
Subsidiaries with the concurrence of its independent certified public
accountants and such changes in GAAP result in a change in the method of
calculation or the interpretation of any of the financial covenants, standards
or terms found in Section 8.1 or Article 10 or any other provision of this
Agreement, the Borrower and the Required Lenders agree to amend any such
affected terms and provisions so as to reflect such changes in GAAP with the
result that the criteria for evaluating the Borrower's or such Subsidiaries'
financial condition shall be the same after such changes in GAAP as if such
changes in GAAP had not been made; provided that, until any necessary amendments
have been made, the certificate required to be delivered under Section 8.1(c)
hereof demonstrating compliance with Article 10 shall include calculations
setting forth the adjustments from the relevant items as shown in the current
financial statements based on the changes to GAAP to the corresponding items
based on GAAP as used in the financial statements referenced in Section 7.2(a),
in order to demonstrate how such financial covenant compliance was derived from
the current financial statements.

liability thereunder.

deposited directly, as received, into a collection account of the Borrower or

Borrower or any of its Subsidiaries is or becomes aware of any material right or
claim (or probable right or claim) of indemnification in favor of it arising

the Administrative Agent for the benefit of the Administrative Agent and the
Lenders (unless such pledge is not required by Article 5 hereof) and shall be

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 84

extensions or refinancings of such Debt which do not increase the outstanding
principal amount of such Debt and the terms and provisions of which are not
materially more onerous than the terms and conditions of such Debt on the
Closing Date, (ii) purchase money Debt secured by purchase money Liens, which
Debt and Liens are permitted under and meet all of the requirements of clause
(g) of the definition of Permitted Liens contained in Section 1.1, and (iii)

benefits under any Plan if and to the extent that the existence of such
liabilities will not constitute, cause or result in a Default; provided,
however, that, notwithstanding anything to the contrary contained in this
Section 9.1, none of the Debt referred to in this Section 9.1 may be incurred,
created or assumed by any Canadian Subsidiary except that Dynamex Canada may
incur or create Debt permitted in accordance with clause (c) and clause (f) of

other than, with respect to Dynamex Canada only, the existing Liens disclosed on
Schedule 1.1(a) hereto which are expressly described on Schedule 1.1(a) as
attaching to Property of Dynamex Canada). With respect to the Capital Stock of

prohibitions contained in this Section 9.2.

not permit any of its Subsidiaries to, (a) become a party to a merger,
consolidation, amalgamation or wind-up, (b) wind-up, dissolve or liquidate
itself, or (c) purchase or acquire all or a material or substantial part of the

            if) (A) the Borrower or such Wholly-Owned Subsidiary of the
            Borrower, respectively, is the surviving entity in such merger or
            wind-up, (B) the surviving entity in such merger or wind-

            up, if a Wholly-Owned Subsidiary of the Borrower, shall be
            incorporated or organized in a state of the U.S. unless all
            non-surviving entities in such merger or wind-up are not
            incorporated or organized in a state of the U.S., (C) at the time of
            such merger or wind-up, each of the Subsidiaries of the Borrower
            which are parties to such merger or wind-up is Solvent, and (D) no
            Default exists at the time of such merger or wind-up or would result
            therefrom; and

      (ii)  the Borrower and its Wholly-Owned Subsidiaries may, subject to
            compliance with the requirements of this Agreement (including,
            without limitation, Sections 5.3, 5.4 and 8.17), make or consummate
            Permitted Acquisitions;

provided, however, that no Permitted Acquisitions may be made if (1) a Default
exists at the time of such Permitted Acquisition or would result therefrom, or
(2) the ratio of Total Debt to EBITDA for the most recent four fiscal quarters
of the Borrower then ended, calculated in accordance with Section 10.1, is
greater than 3.00 to 1.00 unless such Permitted Acquisition has been approved in
writing by the Required Lenders.

      Section 9.4    Restricted Payments. Each of the Loan Parties will not, and
will not permit any of its Subsidiaries to, make any Restricted Payments,
except:

      (a)   subject to the subordination provisions relating thereto, (i) the
Borrower may make regularly scheduled payments of interest accrued on any
Permitted Subordinated Debt and may pay principal of Permitted Subordinated Debt
if and to the extent (but only if and to the extent) permitted by the express
terms of the Subordinated Debt Documents governing such Permitted Subordinated
Debt, which terms have been expressly approved in writing by the Administrative
Agent and (ii) Subsidiaries of the Borrower may make payments of principal and
interest accrued on subordinated intercompany Debt which is permitted to be
incurred in accordance with Section 9.1(c) if and to the extent (but only if and
to the extent) that such payments are permitted by the terms of the documents
governing such subordinated intercompany Debt, which terms have been expressly
approved in writing by the Administrative Agent;

      (b)   Subsidiaries of the Borrower owned by the Borrower may declare and
pay dividends to the Borrower to the extent permitted by applicable law;

      (c)   Subsidiaries of the Borrower owned by Subsidiaries of the Borrower

      (d)   the Borrower may purchase shares of Dynamex Common Stock from
employees of the Borrower or its Subsidiaries upon the termination of the
employment of such employees, provided that the amount paid therefor shall not
exceed the fair market value of such shares to be purchased and shall not exceed
$100,000 in the aggregate during any fiscal year; and

      (e)   the Borrower and its Subsidiaries may make Loans to any officer,
director or shareholder of the Borrower or any of its Subsidiaries (other than a

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 86
<PAGE>
Borrower or a Subsidiary of the Borrower) which, when aggregated with all such
other loans, do not exceed $100,000 in aggregate amount at any time outstanding;
provided, however, that no Restricted Payments may be made pursuant to clauses
(a) or (d) preceding if a Default exists at the time of such Restricted Payment
or would result therefrom.

of intent to accelerate, protest or other formalities of any kind, all of which

Commitments of all of the Lenders (including, without limitation, any obligation
of the Issuing Bank to issue Letters of Credit) shall immediately and
automatically terminate, and the outstanding principal of and accrued and unpaid
interest on the Loans and all other amounts payable by the Loan Parties under
the Loan Documents shall thereupon become immediately and automatically due and
payable, and (ii) upon the occurrence of an Event of Default under clause (iv)

the Loan Documents, the Administrative Agent may, at the direction of the
Required Lenders, perform or attempt to perform, or may cause any Lender (with
the consent of such Lender) to perform or attempt to perform, such covenant or
agreement on behalf of such Loan Party. In such event, the Borrower shall, at
the request of the Administrative Agent, promptly pay any amount expended by the
Administrative Agent or the Lenders in connection with such performance or
attempted performance to the Administrative Agent at the Principal Office,
together with interest thereon at the applicable Default Rate from and including

Administrative Agent nor any Lender shall have any liability or responsibility
for the performance of any obligation of the Borrower or any other Loan Party
under this Agreement or any of the other Loan Documents.

                                                                    EXHIBIT 10.8

         Section 11.4 Judgment Currency. If, for the purpose of obtaining
judgment in any court in any jurisdiction with respect to this Agreement or any
other Loan Document or the Collateral, it becomes necessary to convert into the
currency of such jurisdiction (herein called the "Judgment Currency") any amount
due hereunder in any currency other than the Judgment Currency, then conversion
shall be made at the rate of exchange prevailing on the Business Day before the
day on which judgment is given. For this purpose, "rate of exchange" means the
rate at which the Administrative Agent is able, on the relevant date, to sell
the currency of the amount due hereunder in Toronto, Ontario against the
Judgment Currency. In the event that there is a change in the rate of exchange
prevailing between the Business Day before the day on which the judgment is
given and the date of payment of the amount due, the Borrower agrees that it
will, on the date of payment, pay such additional amounts (if any) as may be
necessary to ensure that the amount paid on such date is the amount in the
Judgment Currency which, when converted at the rate of exchange prevailing on
the date of payment, is the amount then due under this Agreement in Cdn. Dollars
or Dollars, as the case may be. Any additional amount due under this Section
11.4 will be due as a separate indebtedness and shall not be affected by
judgment being obtained for any other sums due under or in respect of this
Agreement or any other Loan Document.

         Section 11.5 Cash Collateral. If an Event of Default shall have
occurred and be continuing, the Borrower shall, if requested by the
Administrative Agent or the Required Lenders, pledge to the Administrative Agent
as security for the Obligations an amount in immediately available funds equal
to the then outstanding Letter of Credit Liabilities, such funds to be held in a
cash collateral account satisfactory to the Administrative Agent without any
right of withdrawal by the Borrower.

                                   ARTICLE 12

                            The Administrative Agent

         Section 12.1 Appointment, Powers and Immunities. Each Lender hereby
irrevocably appoints and authorizes the Administrative Agent to act as its agent
hereunder and under the other Loan Documents with such powers as are
specifically delegated to the Administrative Agent by the terms of this
Agreement and the other Loan Documents, together with such other powers as are
reasonably incidental thereto. Neither the Administrative Agent nor any of its
Affiliates, officers, directors, employees, attorneys or agents shall be liable
for any action taken or omitted to be taken by any of them hereunder or
otherwise in connection with this Agreement or any of the other Loan Documents
except for its or their own gross negligence or willful misconduct. Without
limiting the generality of the preceding sentence, the Administrative Agent (a)
may treat the payee of any Note as the holder thereof until the Administrative
Agent receives written notice of the assignment or transfer thereof signed by
such payee and in form satisfactory to the Administrative Agent, (b) shall have
no duties or responsibilities except those expressly set forth in this Agreement
and the other Loan Documents, and shall not by reason of this Agreement or any
other Loan Document be a trustee or fiduciary for any Lender, (c) shall not be
required to initiate any litigation or collection proceedings hereunder or under
any other Loan Document except to the extent requested by the Required Lenders,
(d) shall not be responsible to the Lenders for any recitals, statements,
representations or warranties contained in this

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 97
<PAGE>
Agreement or any other Loan Document, or any certificate or other document
referred to or provided for in, or received by any of them under, this Agreement
or any other Loan Document, or for the value, validity, effectiveness,
enforceability or sufficiency of this Agreement or any other Loan Document or
any other document referred to or provided for herein or therein or for any
failure by any Person to perform any of its obligations hereunder or thereunder,
(e) may consult with legal counsel (including counsel for any Loan Party),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts, and (f)
shall incur no liability under or in respect of any Loan Document by acting upon
any notice, consent, certificate or other instrument or writing reasonably
believed by it to be genuine and signed or sent by the proper party or parties.
As to any matters not expressly provided for by this Agreement, the
Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, hereunder in accordance with instructions signed by the
Required Lenders, and such instructions of the Required Lenders and any action
taken or failure to act pursuant thereto shall be binding on all of the Lenders;
provided, however, that the Administrative Agent shall not be required to take
any action which exposes the Administrative Agent to liability or which is
contrary to this Agreement or any other Loan Document or applicable law.

         Section 12.2 Rights of Administrative Agent as a Lender. With respect
to its Commitment, the Loans made by it and the Note issued to it, Bank of
America (and any successor acting as Administrative Agent) in its capacity as a
Lender hereunder shall have the same rights and powers hereunder as any other
Lender and may exercise the same as though it were not acting as the
Administrative Agent, and the term "Lender" or "Lenders" shall, unless the
context otherwise indicates, include the Administrative Agent in-its individual
capacity. The Administrative Agent and its Affiliates may (without having to
account therefor to any Lender) accept deposits from, lend money to, act as
trustee under indentures of, provide merchant banking services to, own
securities of, and generally engage in any kind of banking, trust or other
business with, the Loan Parties or any of their Affiliates and any other Person
who may do business with or own securities of the Loan Parties or any of their
Affiliates, all as if it were not acting as the Administrative Agent and without
any duty to account therefor to the Lenders.

         Section 12.3 Defaults. The Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of a Default (other than the
non-payment of principal of or interest on the Loans or of commitment fees)
unless the Administrative Agent has received notice from a Lender or the
Borrower specifying such Default and stating that such notice is a "notice of
default". In the event that the Administrative Agent receives such a notice of
the occurrence of a Default, the Administrative Agent shall give prompt notice
thereof to the Lenders (and shall give each Lender prompt notice of each such
non-payment). The Administrative Agent shall (subject to Section 12.1) take such
action with respect to such Default as shall be directed by the Required
Lenders, provided that unless and until the Administrative Agent shall have
received such directions, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default as it shall seem advisable and in the best interest of the
Lenders.

         Section 12.4 INDEMNIFICATION. EACH LENDER HEREBY AGREES TO INDEMNIFY
THE ADMINISTRATIVE AGENT FROM AND HOLD THE ADMINISTRATIVE AGENT HARMLESS AGAINST

THE OBLIGATIONS OF THE LOAN PARTIES UNDER SECTIONS 13.1 AND 13.2), RATABLY IN
ACCORDANCE WITH ITS PRO RATA SHARE (CALCULATED ON THE BASIS OF ITS AGGREGATE
PERCENTAGE), ANY AND ALL LIABILITIES (INCLUDING, WITHOUT LIMITATION,
ENVIRONMENTAL LIABILITIES), OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
JUDGMENTS, DEFICIENCIES, SUITS, COSTS, EXPENSES (INCLUDING ATTORNEYS' FEES) AND
DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED
BY OR ASSERTED AGAINST THE ADMINISTRATIVE AGENT IN ANY WAY RELATING TO OR
ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY ACTION TAKEN OR OMITTED TO BE
TAKEN BY THE ADMINISTRATIVE AGENT UNDER OR IN RESPECT OF ANY OF THE LOAN
DOCUMENTS; PROVIDED, FURTHER, THAT NO LENDER SHALL BE LIABLE FOR ANY PORTION OF
THE FOREGOING TO THE EXTENT CAUSED BY THE ADMINISTRATIVE AGENT'S GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT. WITHOUT LIMITATION OF THE FOREGOING, IT IS THE
EXPRESS INTENTION OF THE LENDERS THAT THE ADMINISTRATIVE AGENT SHALL BE
INDEMNIFIED HEREUNDER FROM AND HELD HARMLESS AGAINST ALL OF SUCH LIABILITIES
(INCLUDING, WITHOUT LIMITATION, ENVIRONMENTAL LIABILITIES), OBLIGATIONS, LOSSES,
DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, DEFICIENCIES, SUITS, COSTS, EXPENSES
(INCLUDING ATTORNEYS' FEES) AND DISBURSEMENTS OF ANY KIND OR NATURE DIRECTLY OR
INDIRECTLY ARISING OUT OF OR RESULTING FROM THE SOLE OR CONTRIBUTORY NEGLIGENCE
OF THE ADMINISTRATIVE AGENT (EXCEPT TO THE EXTENT THE SAME ARE CAUSED BY THE
ADMINISTRATIVE AGENT'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT). WITHOUT LIMITING
ANY OTHER PROVISION OF THIS SECTION 12.4, EACH LENDER AGREES TO REIMBURSE THE
ADMINISTRATIVE AGENT PROMPTLY UPON DEMAND FOR ITS PRO RATA SHARE (CALCULATED ON
THE BASIS OF ITS AGGREGATE PERCENTAGE) OF ANY AND ALL OUT-OF-POCKET EXPENSES
(INCLUDING ATTORNEYS' FEES) INCURRED BY THE ADMINISTRATIVE AGENT IN CONNECTION
WITH THE PREPARATION, EXECUTION, DELIVERY, ADMINISTRATION, MODIFICATION,
AMENDMENT OR ENFORCEMENT (WHETHER THROUGH NEGOTIATIONS, LEGAL PROCEEDINGS OR
OTHERWISE) OF, OR LEGAL ADVICE IN RESPECT OF RIGHTS OR RESPONSIBILITIES UNDER,
THE LOAN DOCUMENTS, TO THE EXTENT THAT THE ADMINISTRATIVE AGENT IS NOT PROMPTLY
REIMBURSED FOR SUCH EXPENSES BY THE BORROWER.

         Section 12.5 Independent Credit Decisions. Each Lender agrees that it
has independently and without reliance on the Administrative Agent or any other
Lender, and based on such documents and information as it has deemed
appropriate, made its own credit analysis of

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 99
<PAGE>
the Borrower and its Subsidiaries and the other Loan Parties and its own
decision to enter into this Agreement and that it will, independently and
without reliance upon the Administrative Agent or any other Lender, and based
upon such documents and information as it shall deem appropriate at the time,
continue to make its own analysis and decisions in taking or not taking action
under this Agreement or any of the other Loan Documents. The Administrative
Agent shall not be required to keep itself informed as to the performance or
observance by any Loan Party of this Agreement or any other Loan Document or to
inspect the Properties or books of any Loan Party. Except for notices, reports
and other documents and information expressly required to be furnished to the
Lenders by the Administrative Agent hereunder or under the other Loan Documents,
the Administrative Agent shall not have any duty or responsibility to provide
any Lender with any credit or other financial information concerning the
affairs, financial condition or business of any Loan Party (or any of its
Affiliates) which may come into the possession of the Administrative Agent or
any of its Affiliates.

         Section 12.6 Several Commitments. The Commitments and other obligations
of the Lenders under this Agreement are several. The default by any Lender in
making a Loan in accordance with its Commitment shall not relieve the other
Lenders of their obligations under this Agreement. In the event of any default
by any Lender in making any Loan, each nondefaulting Lender shall be obligated
to make its Loan but shall not be obligated to advance the amount which the
defaulting Lender was required to advance hereunder. In no event shall any
Lender be required to advance an amount or amounts with respect to any of the
Loans which would in the aggregate exceed such Lender's Commitment with respect
to such Loans. No Lender shall be responsible for any act or omission of any
other Lender.

         Section 12.7 Successor Administrative Agent. Subject to the appointment
and acceptance of a successor Administrative Agent as provided below, the
Administrative Agent may resign at any time by giving notice thereof to the
Lenders and the Borrower. Upon any such resignation, the Required Lenders will
have the right to appoint another Lender as a successor Administrative Agent. If
no successor Administrative Agent shall have been so appointed by the Required
Lenders and shall have accepted such appointment within 30 days after the
retiring Administrative Agent's giving of notice of resignation, then the
retiring Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be a commercial bank organized under the laws
of the U.S. or any state thereof or of a foreign country if acting through its
U.S. branch and having combined capital and surplus of at least $100,000,000.
Upon the acceptance of its appointment as successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested with
all rights, powers, privileges, immunities and duties of the resigning
Administrative Agent, and the resigning Administrative Agent shall be discharged
from its duties and obligations under this Agreement and the other Loan
Documents. After any Administrative Agent's resignation as Administrative Agent,
the provisions of this Article 12 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was the
Administrative Agent. Each Administrative Agent (including each successor
Administrative Agent) agrees that, so long as it is acting as Administrative
Agent under this Agreement, it shall be a Lender under this Agreement. The
Borrower, the Administrative Agent and the Lenders agree that, except for
successor Administrative Agents appointed in accordance with this Section 12.7,
no agents or

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 100
<PAGE>
co-agents other than the Administrative Agent may be appointed under this
Agreement or any other Loan Document without the prior written consent of the
Administrative Agent and Banc of America Securities LLC.

         Section 13.2 INDEMNIFICATION. EACH OF THE LOAN PARTIES HEREBY JOINTLY
AND SEVERALLY AGREES TO INDEMNIFY THE ADMINISTRATIVE AGENT AND EACH LENDER AND
EACH AFFILIATE THEREOF AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES,

AGAINST, ANY AND ALL LOSSES, LIABILITIES (INCLUDING, WITHOUT LIMITATION,
ENVIRONMENTAL LIABILITIES), CLAIMS, DAMAGES, PENALTIES, JUDGMENTS,
DISBURSEMENTS, COSTS AND EXPENSES (INCLUDING REASONABLE ATTORNEYS' AND
CONSULTANTS' FEES) TO WHICH ANY OF THEM MAY BECOME SUBJECT WHICH DIRECTLY OR
INDIRECTLY ARISE FROM OR RELATE TO (A) THE NEGOTIATION, EXECUTION, DELIVERY,
PERFORMANCE, ADMINISTRATION OR ENFORCEMENT OF ANY OF THE LOAN DOCUMENTS, (B) ANY
OF THE TRANSACTIONS CONTEMPLATED BY THE LOAN DOCUMENTS, (C) THE RELATED
TRANSACTIONS, (D) ANY BREACH BY ANY LOAN PARTY OF ANY

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 101
<PAGE>
REPRESENTATION, WARRANTY, COVENANT OR OTHER AGREEMENT CONTAINED IN ANY OF THE
LOAN DOCUMENTS, (E) THE USE OR PROPOSED USE OF ANY LOAN OR PROCEEDS THEREOF OR
LETTER OF CREDIT, (F) ANY AND ALL TAXES, LEVEES, DEDUCTIONS AND CHARGES IMPOSED
ON THE ADMINISTRATIVE AGENT, THE ISSUING BANK OR ANY LENDER IN RESPECT OF ANY
LOAN OR LETTER OF CREDIT, (G) THE PRESENCE, RELEASE, THREATENED RELEASE,
DISPOSAL, REMOVAL OR CLEANUP OF ANY HAZARDOUS MATERIAL LOCATED ON, ABOUT, WITHIN
OR AFFECTING ANY OF THE PROPERTIES OF ANY LOAN PARTY, EXCEPT TO THE EXTENT THAT
THE LOSS, DAMAGE OR CLAIM IS THE DIRECT RESULT OF AN INTENTIONAL AND AFFIRMATIVE
ACT BY THE PERSON TO BE INDEMNIFIED THAT CONSTITUTES GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF SUCH PERSON, OR (H) ANY INVESTIGATION, LITIGATION OR OTHER
PROCEEDING, INCLUDING, WITHOUT LIMITATION, ANY THREATENED INVESTIGATION,
LITIGATION OR OTHER PROCEEDING RELATING TO ANY OF THE FOREGOING; BUT EXCLUDING
ANY OF THE FOREGOING TO THE EXTENT CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF THE PERSON TO BE INDEMNIFIED. WITHOUT LIMITING ANY PROVISION OF
THIS AGREEMENT OR OF ANY OTHER LOAN DOCUMENT, IT IS THE EXPRESS INTENTION OF THE
PARTIES HERETO THAT EACH PERSON TO BE INDEMNIFIED UNDER THIS SECTION 13.2 SHALL
BE INDEMNIFIED FROM AND HELD HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES
(INCLUDING, WITHOUT LIMITATION, ENVIRONMENTAL LIABILITIES), CLAIMS, DAMAGES,
PENALTIES, JUDGMENTS, DISBURSEMENTS, COSTS AND EXPENSES (INCLUDING REASONABLE
ATTORNEYS' FEES) ARISING OUT OF OR RESULTING FROM THE SOLE OR CONTRIBUTORY
NEGLIGENCE OF SUCH PERSON. WITHOUT PREJUDICE TO THE SURVIVAL OF ANY OTHER TERM
OR PROVISION OF THIS AGREEMENT, THE OBLIGATIONS OF THE LOAN PARTIES UNDER THIS
SECTION 13.2 SHALL SURVIVE THE REPAYMENT OF THE LOANS AND OTHER OBLIGATIONS AND
TERMINATION OF THE COMMITMENTS.

         Section 13.3 Limitation of Liability. None of the Administrative Agent,
any Lender or any Affiliate, officer, director, employee, attorney or agent
thereof shall be liable for any error of judgment or act done in good faith, or
be otherwise liable or responsible under any circumstances whatsoever (including
such Person's negligence), except for such Person's gross negligence or willful
misconduct. None of the Administrative Agent, any Lender or any Affiliate,
officer, director, employee, attorney or agent thereof shall have any liability
with respect to, and each of the Loan Parties hereby waives, releases and agrees
not to sue any of them upon, any claim for any special, indirect, incidental or
consequential damages suffered or incurred by the Borrower or any other Loan
Party in connection with, arising out of or in any way related to this Agreement
or any of the other Loan Documents, or any of the transactions contemplated by
this Agreement or any of the other Loan Documents. Each of the Loan Parties
hereby waives, releases and agrees not to sue the Administrative Agent or any
Lender or any of their respective Affiliates, officers, directors, employees,
attorneys or agents for exemplary or punitive damages in respect of any claim in
connection with, arising out of or in any way related to this Agreement

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 102
<PAGE>
or any of the other Loan Documents, or any of the transactions contemplated by
this Agreement or any of the other Loan Documents.

         Section 13.4 No Duty. All attorneys, accountants, appraisers and other
professional Persons and consultants retained by the Administrative Agent and
the Lenders shall have the right to act exclusively in the interest of the
Administrative Agent and the Lenders and shall have no duty of disclosure, duty
of loyalty, duty of care or other duty or obligation of any type or nature
whatsoever to the Borrower or any of its Subsidiaries or any of their
shareholders or Affiliates or any other Person.

         Section 13.5 No Fiduciary Relationship. The relationship between each
Loan Party and each Lender is solely that of debtor and creditor, and neither
the Administrative Agent nor any Lender has any fiduciary or other special
relationship with the Borrower or any other Loan Party, and no term or condition
of any of the Loan Documents shall be construed so as to deem the relationship
between the Borrower and any Lender, or any other Loan Party and any Lender, to
be other than that of debtor and creditor. No joint venture or partnership is
created by this Agreement among the Lenders or among the Borrower or any other
Loan Party and the Lenders.

         Section 13.6 Equitable Relief. Each of the Loan Parties recognizes
that, in the event it fails to pay, perform, observe or discharge any or all of
the Obligations, any remedy at law may prove to be inadequate relief to the
Administrative Agent and the Lenders. Each of the Loan Parties therefore agrees
that the Administrative Agent and the Lenders, if the Administrative Agent or
the Lenders so request, shall be entitled to temporary and permanent injunctive
relief in any such case without the necessity of proving actual damages.

         Section 13.7 No Waiver; Cumulative Remedies. No failure on the part of
the Administrative Agent or any Lender to exercise and no delay in exercising,
and no course of dealing with respect to, any right, power or privilege under
this Agreement or any other Loan Document shall operate as a waiver thereof, nor
shall any single or partial exercise of any right, power or privilege under this
Agreement or any other Loan Document preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. The rights and
remedies provided for in this Agreement and the other Loan Documents are
cumulative and not exclusive of any rights and remedies provided by law.

         Section 13.8 Successors and Assigns.

         (a) This Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns. Neither the
Borrower nor any other Loan Party may assign or transfer any of its rights or
obligations under this Agreement or any other Loan Document without the prior
written consent of the Administrative Agent and the Lenders. Any Lender may sell
participations in all or a portion of its rights and obligations under this
Agreement and the other Loan Documents (including, without limitation, all or a
portion of its Commitment and the Loans owing to it); provided, however, that
(i) such Lender's obligations under this Agreement and the other Loan Documents
(including, without limitation, its Commitment) shall remain unchanged, (ii)
such Lender shall remain solely responsible to the Borrower for the performance
of such obligations, (iii) such Lender shall remain the holder of its Note for
all purposes of this Agreement, (iv) the Loan Parties shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and the other Loan Documents, and (v) the
Lenders shall not grant any participation under which the participant shall have
the right to approve (or under which the consent of the participant must be
obtained prior to the Lenders being able to approve) any amendment or waiver of
this Agreement or the other Loan Documents, except to the extent that such
amendment or waiver (A) increases any Commitment, (B) reduces the interest rate
or the amount of principal or fees applicable to the Loans in which such
participant is participating, (C) extends the Maturity Date, (D) releases any of
the Collateral (except as provided for herein or in any Loan Document) or any
guaranty of the Obligations, or (E) releases the Borrower from any of its
monetary Obligations under any of the Loan Documents.

         (b) Each of the Loan Parties and each of the Lenders agree that any
Lender (the "Assigning Lender") may at any time assign to one or more Eligible
Assignees all, or a proportionate part of all, of its rights and/or obligations
under this Agreement and the other Loan Documents (including, without
limitation, its Commitment and/or Loans) (each an "Assignee"); provided,
however, that (i) each such assignment may be of a varying percentage of the
Assigning Lender's rights and/or obligations under this Agreement and the other
Loan Documents and may relate to some but not all of such rights and/or
obligations, (ii) except in the case of an assignment of all of a Lender's
rights and obligations under this Agreement and the other Loan Documents, the
amount of the Commitment and/or Loans of the Assigning Lender being assigned
pursuant to each assignment (determined as of the date of the Assignment and
Acceptance with respect to such assignment) shall in no event be less than the
lesser of (A) an amount equal to $5,000,000 calculated based upon the Commitment
assigned (or, if such Commitment has terminated or expired, the aggregate
outstanding principal amount of the Loans and the Letter of Credit Liabilities
assigned), or (B) an amount equal to ten percent of the aggregate Commitments
(or, if such Commitments have terminated or expired, the aggregate outstanding
principal amount of the Loans and the Letter of Credit Liabilities), and (iii)
the parties to each such assignment shall execute and deliver to the
Administrative Agent for its acceptance and recording in the Register (as
defined below), an Assignment and Acceptance, together with the Note subject to
such assignment, and a processing and recordation fee of $3,500. Upon such
execution, delivery, acceptance and recording, from and after the effective date
specified in each Assignment and Acceptance, which effective date shall be at
least five

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 104
<PAGE>
Business Days after the execution thereof or such other date as may be approved
by the Administrative Agent, (1) the Assignee thereunder shall be a party hereto
as a "Lender" and, to the extent that rights and obligations hereunder have been
assigned to it pursuant to such Assignment and Acceptance, have the rights and
obligations of a Lender hereunder and under the Loan Documents, and (2) the
Assigning Lender thereunder shall, to the extent that rights and obligations
hereunder have been assigned by it pursuant to such Assignment and Acceptance,
relinquish its rights and be released from its obligations under this Agreement
and the other Loan Documents (and, in the case of an Assignment and Acceptance
covering all or the remaining portion of a Lender's rights and obligations under
the Loan Documents, such Lender shall cease to be a party thereto, provided that
such Lender's rights under Article 4, Section 13.1 and Section 13.2 accrued
through the date of assignment shall continue).

         (c) By executing and delivering an Assignment and Acceptance, the
Assigning Lender thereunder and the Assignee thereunder confirm to and agree
with each other and the other parties hereto as follows: (i) other than as
provided in such Assignment and Acceptance, such Assigning Lender makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with the Loan
Documents or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of the Loan Documents or any other instrument or document
furnished pursuant thereto; (ii) such Assigning Lender makes no representation
or warranty and assumes no responsibility with respect to the financial
condition or results of operations of any Loan Party or the performance or
observance by any Loan Party of its obligations under the Loan Documents; (iii)
such Assignee confirms that it has received a copy of the Loan Documents,
together with copies of the financial statements referred to in Section 7.2 and
such other documents and information as it has deemed appropriate to make its
own credit analysis and decision to enter into such Assignment and Acceptance;
(iv) such Assignee will, independently and without reliance upon the
Administrative Agent or such Assigning Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement and the
other Loan Documents; (v) such Assignee confirms that it is an Eligible
Assignee; (vi) such Assignee appoints and authorizes the Administrative Agent to
take such action as agent on its behalf and exercise such powers under the Loan
Documents as are delegated to the Administrative Agent by the terms thereof,
together with such powers as are reasonably incidental thereto; and (vii) such
Assignee agrees that it will perform in accordance with their terms all of the
obligations which by the terms of the Loan Documents are required to be
performed by it as a Lender.

         (d) The Administrative Agent shall maintain at its Principal Office a
copy of each Assignment and Acceptance delivered to and accepted by it and a
register for the recordation of the names and addresses of the Lenders and the
Commitment of, and principal amount of the Loans owing to, each Lender from time
to time (the "Register"). The entries in the Register shall be conclusive and
binding for all purposes, absent manifest error, and the Loan Parties, the
Administrative Agent and the Lenders may treat each Person whose name is
recorded in the Register as a Lender hereunder for all purposes under the Loan
Documents. The Register shall be available for inspection by any Loan Party or
any Lender at any reasonable time and from time to time upon reasonable prior
notice.

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 105
<PAGE>
         (e) Upon its receipt of an Assignment and Acceptance executed by an
Assigning Lender and Assignee representing that it is an Eligible Assignee,
together with the Note subject to such assignment, the Administrative Agent
shall, if such Assignment and Acceptance has been completed and is in
substantially the form of Exhibit A hereto, (i) accept such Assignment and
Acceptance, (ii) record the information contained therein in the Register, and
(iii) give prompt written notice thereof to the Borrower. Within five Business
Days after its receipt of such notice, the Borrower, at its expense, shall
execute and deliver to the Administrative Agent in exchange for each surrendered
Note evidencing the Loans assigned, a new Note evidencing such Loans payable to
the order of such Eligible Assignee in an amount equal to such Loans assigned to
it and, if the Assigning Lender has retained any Loans, a new Note evidencing
each such Loans payable to the order of the Assigning Lender in the amount of
such Loans retained by it (each such promissory note shall constitute a "Note"
for purposes of the Loan Documents). Such new Notes shall be dated the effective
date of such Assignment and Acceptance and shall otherwise be in substantially
the form of Exhibit B hereto.

         (f) Any Lender may, in connection with any assignment or participation
or proposed assignment or participation pursuant to this Section 13.8, disclose
to the Assignee or participant or proposed Assignee or participant any
information relating to the Borrower or any of its Subsidiaries or Affiliates or
any other Loan Party furnished to such Lender by or on behalf of the Borrower or
any of its Subsidiaries or Affiliates or any other Loan Party; provided that
each such actual or proposed Assignee or participant shall agree to be bound by
the provisions of Section 13.20.

         (g) Any Lender may assign and pledge the Note held by it to any Federal
Reserve Bank or the U.S. Treasury as collateral security pursuant to Regulation
A of the Board of Governors of the Federal Reserve System and any operating
circular issued by such Federal Reserve System and/or Federal Reserve Bank;
provided, however, that any payment made by the Borrower for the benefit of such
assigning and/or pledging Lender in accordance with the terms of the Loan
Documents shall satisfy the Borrower's obligations under the Loan Documents in
respect thereof to the extent of such payment. No such assignment and/or pledge
shall release the assigning and/or pledging Lender from its obligations
hereunder.

         (h) The Borrower shall maintain, or cause to be maintained, a register
(the "Registered Note Register") (which, at the request of the Borrower (which
request the Borrower makes by the execution of this Agreement), shall be kept by
the Administrative Agent on behalf of the Borrower at no extra charge to the
Borrower at the address to which notices to the Administrative Agent are to be
sent hereunder) on which it shall enter the name of the registered owner of each
of the Loans which is evidenced by a Registered Note. Notwithstanding anything
to the contrary contained in this Section 13.8, a Registered Note and the Loans
evidenced thereby may be assigned or otherwise transferred in whole or in part
only by registration of such assignment or transfer of such Registered Note and
the Loans evidenced thereby on the Registered Note Register (and each Registered
Note shall expressly so provide). Any assignment or transfer of all or part of
such Loans and the Registered Note evidencing the same shall be registered on
the Registered Note Register only upon surrender for registration of

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 106
<PAGE>
assignment or transfer of the Registered Note evidencing such Loans, duly
endorsed by (or accompanied by a written instrument of assignment or transfer
duly executed by) the registered noteholder thereof, and thereupon one or more
new Registered Notes in the same aggregate principal amount shall be issued to
the designated assignee(s) or transferee(s). Prior to the due presentment for
registration of transfer of any Registered Note, the Borrower and the
Administrative Agent shall treat the Person in whose name such Loans and the
Registered Note(s) evidencing the same are registered as the owner thereof for
the purpose of receiving all payments thereon and for all other purposes,
notwithstanding any notice to the contrary. The Registered Note Register shall
be available for inspection by the Borrower and any Lender at any reasonable
time upon reasonable prior notice.

         Section 13.9 Survival. All representations and warranties made or
deemed made in this Agreement or any other Loan Document or in any document,
statement or certificate furnished in connection with this Agreement shall
survive the execution and delivery of this Agreement and the other Loan
Documents and the making of the Loans, and no investigation by the
Administrative Agent or any Lender or any closing shall affect the
representations and warranties or the right of the Administrative Agent or any
Lender to rely upon them. Without prejudice to the survival of any other
obligation of any Loan Party hereunder, the obligations of such Loan Party under
Article 4 and Sections 13.1 and 13.2 shall survive repayment of the Loans and
the Reimbursement Obligations and the other Obligations.

         Section 13.10 ENTIRE AGREEMENT. THIS AGREEMENT, THE NOTES AND THE OTHER
LOAN DOCUMENTS REFERRED TO HEREIN EMBODY THE FINAL, ENTIRE AGREEMENT AMONG THE
PARTIES HERETO AND SUPERSEDE ANY AND ALL PRIOR COMMITMENTS (INCLUDING, WITHOUT
LIMITATION, THE COMMITMENT LETTER), TERM SHEETS, AGREEMENTS, REPRESENTATIONS AND
UNDERSTANDINGS, WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT MATTER HEREOF
AND MAY NOT BE CONTRADICTED OR VARIED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS OF THE PARTIES HERETO. THERE ARE NO
UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES HERETO.

         Section 13.11 Amendments. No amendment or waiver of any provision of
this Agreement, the Notes or any other Loan Document to which any Loan Party is
a party, nor any consent to any departure by such Loan Party therefrom, shall in
any event be effective unless the same shall be agreed or consented to by the
Required Lenders and the applicable Loan Party or Loan Parties in writing, and
each such waiver or consent shall be effective only in the specific instance and
for the writing, and each such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given; provided,
however, that no amendment, waiver or consent shall, unless in writing and
signed by all of the Lenders and the applicable Loan Party or Loan Parties, do
any of the following: (a) increase the Commitments of the Lenders or subject the
Lenders to any additional obligations; (b) reduce the principal of, or interest
on, the Loans or any fees or other amounts payable hereunder; (c) postpone any
date fixed for any payment (including, without limitation, any mandatory
prepayment) of principal of, or interest on, the Loans or any fees or other
amounts payable hereunder; (d) waive any of the

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 107
<PAGE>
conditions precedent specified in Article 6; (e) change the Aggregate
Percentage, the Amortizing Loan Portion Percentage, the Commitment Percentage or
the aggregate unpaid principal amount of the Loans or the number or interests of
the Lenders which shall be required for the Lenders or any of them to take any
action under this Agreement; (f) change any provision contained in Section 3.2,
Section 9.13 or this Section 13.11 or modify the definition of "Borrowing Base",
"Eligible Receivables" or "Required Lenders" contained in Section 1.1; or (g)
except as expressly authorized by this Agreement, release any Collateral from
any of the Liens created by the Security Documents or release any guaranty of
all or any portion of the Obligations; and provided further, however, that no
amendment, waiver or consent relating to Sections 12.1, 12.2, 12.3, 12.4 or 12.5
shall require the agreement of any Loan Party. Notwithstanding anything to the
contrary contained in this Section 13.11, no amendment, waiver or consent shall
be made with respect to Article 12 hereof without the prior written consent of
the Administrative Agent.

         Section 13.12 Maximum Interest Rate.

         (a) No interest rate specified in this Agreement or any other Loan
Document shall at any time exceed the Maximum Rate. If at any time the interest
rate (the "Contract Rate") for any Obligation shall exceed the Maximum Rate,
thereby causing the interest accruing on such Obligation to be limited to the
Maximum Rate, then any subsequent reduction in the Contract Rate for such
Obligation shall not reduce the rate of interest on such Obligation below the
Maximum Rate until the aggregate amount of interest accrued on such Obligation
equals the aggregate amount of interest which would have accrued on such
Obligation if the Contract Rate for such Obligation had at all times been in
effect.

         (b) Notwithstanding anything to the contrary contained in this
Agreement or the other Loan Documents, none of the terms and provisions of this
Agreement or the other Loan Documents shall ever be construed to create a
contract or obligation to pay interest at a rate in excess of the Maximum Rate;
and neither the Administrative Agent nor any Lender shall ever charge, receive,
take, collect, reserve or apply, as interest on the Obligations, any amount in
excess of the Maximum Rate. The parties hereto agree that any interest, charge,
fee, expense or other obligation provided for in this Agreement or in the other
Loan Documents which constitutes interest under applicable law shall be, ipso
facto and under any and all circumstances, limited or reduced to an amount equal
to the lesser of (i) the amount of such interest, charge, fee, expense or other
obligation that would be payable in the absence of this Section 13.12(b) or (ii)
an amount, which when added to all other interest payable under this Agreement
and the other Loan Documents, equals the Maximum Rate. If, notwithstanding the
foregoing, the Administrative Agent or any Lender ever contracts for, charges,
receives, takes, collects, reserves or applies as interest any amount in excess
of the Maximum Rate, such amount which would be deemed excessive interest shall
be deemed a partial payment or prepayment of principal of the Obligations and
treated hereunder as such; and if the Obligations, or applicable portions
thereof, are paid in full, any remaining excess shall promptly be paid to the
applicable Loan Party or Loan Parties (as appropriate). In determining whether
the interest paid or payable, under any specific contingency, exceeds the
Maximum Rate, the Loan Parties, the Administrative Agent and the Lenders shall,
to the maximum extent permitted by applicable law, (i) characterize any
nonprincipal payment as an expense, fee or premium rather than as interest,

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 108
<PAGE>
(ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize,
prorate, allocate and spread in equal or unequal parts the total amount of
interest throughout the entire contemplated term of the Obligations, or
applicable portions thereof, so that the interest rate does not exceed the
Maximum Rate at any time during the term of the Obligations; provided that, if
the unpaid principal balance is paid and performed in full prior to the end of
the full contemplated term thereof, and if the interest received for the actual
period of existence thereof exceeds the Maximum Rate, the Administrative Agent
and/or the Lenders, as appropriate, shall refund to the applicable Loan Party or
Loan Parties (as appropriate) the amount of such excess and, in such event, the
Administrative Agent and the Lenders shall not be subject to any penalties
provided by any laws for contracting for, charging, receiving, taking,
collecting, reserving or applying interest in excess of the Maximum Rate. In
addition to the foregoing, each of the Loan Parties agrees that no provision of
this Agreement or any other Loan Document shall have the effect of imposing on
any Loan Party any obligation to pay interest (as such term is defined in
Section 347 of the Criminal Code of Canada) at a rate in excess of the rate
permitted by the laws of Canada if and to the extent (if any) that such laws are
applicable, after taking into account all other amounts which must be taken into
account for the purpose of such laws, and the obligations of the Loan Parties to
pay interest under this Agreement and the other Loan Documents is so limited.

         (c) Pursuant to Article 15.10(b) of Chapter 15, Subtitle 79, Revised
Civil Statutes of Texas 1925, as amended, each of the Loan Parties agrees that
such Chapter 15 (which regulates certain revolving credit loan accounts and
revolving tri-party accounts) shall not govern or in any manner apply to the
Obligations.

         Section 13.13 Notices. All notices and other communications provided
for in this Agreement and the other Loan Documents to which the Borrower or any
of its Subsidiaries is a party shall be given or made by telecopy or in writing
and telecopied, mailed by certified mail return receipt requested or delivered
to the intended recipient at the "Address for Notices" specified below its name
on the signature pages hereof (or, with respect to a Lender that becomes a party
to this Agreement pursuant to an assignment made in accordance with Section
13.8, in the Assignment and Acceptance executed by it); or, as to any party, at
such other address as shall be designated by such party in a notice to each
other party given in accordance with this Section 13.13. Except as otherwise
provided in this Agreement, all such communications shall be deemed to have been
duly given when transmitted by telecopy or personally delivered or, in the case
of a mailed notice, upon receipt, in each case given or addressed as aforesaid;
provided, however, that notices to the Administrative Agent shall be deemed
given when received by the Administrative Agent.

         Section 13.14 GOVERNING LAW; SUBMISSION TO JURISDICTION; SERVICE OF
PROCESS. EXCEPT AS MAY BE EXPRESSLY STATED TO THE CONTRARY IN CERTAIN LOAN
DOCUMENTS, THIS AGREEMENT, THE NOTES AND THE OTHER LOAN DOCUMENTS SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS
(WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES) AND APPLICABLE LAWS OF THE U.S.
EACH OF THE BORROWER AND EACH OF ITS SUBSIDIARIES

<PAGE>
HEREBY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF EACH OF (1) THE U.S.
DISTRICT COURT FOR THE NORTHERN DISTRICT OF TEXAS, AND (2) ANY TEXAS STATE COURT
SITTING IN DALLAS COUNTY, TEXAS, FOR THE PURPOSES OF ALL LEGAL PROCEEDINGS
ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH OF THE BORROWER AND EACH OF
ITS SUBSIDIARIES HEREBY IRREVOCABLY CONSENTS TO THE SERVICE OF ANY AND ALL
PROCESS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES OF SUCH
PROCESS TO SUCH PERSON AT ITS ADDRESS SET FORTH UNDERNEATH ITS SIGNATURE HERETO.
EACH OF THE BORROWER AND EACH OF ITS SUBSIDIARIES HEREBY IRREVOCABLY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER
HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT
AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT
IN AN INCONVENIENT FORM.

         Section 13.15 Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         Section 13.16 Severability. Any provision of this Agreement held by a
court of competent jurisdiction to be invalid or unenforceable shall not impair
or invalidate the remainder of this Agreement and the effect thereof shall be
confined to the provision held to be invalid or illegal.

         Section 13.17 Headings. The headings, captions and arrangements used in
this Agreement are for convenience only and shall not affect the interpretation
of this Agreement.

         Section 13.18 Construction. Each of the Borrower and each of its
Subsidiaries, the Administrative Agent and each Lender acknowledges that it has
had the benefit of legal counsel of its own choice and has been afforded an
opportunity to review this Agreement and the other Loan Documents with its legal
counsel and that this Agreement and the other Loan Documents shall be construed
as if jointly drafted by the parties hereto.

         Section 13.19 Independence of Covenants. All covenants hereunder shall
be given independent effect so that if a particular action or condition is not
permitted by any of such covenants, the fact that it would be permitted by an
exception to, or be otherwise within the limitations of, another covenant shall
not avoid the occurrence of a Default if such action is taken or such condition
exists.

         Section 13.20 Confidentiality. Each Lender agrees to exercise its best
efforts to keep any information delivered or made available by any Loan Party to
it which is clearly indicated to be confidential information, confidential from
anyone other than Persons employed or retained by such Lender who are or are
expected to become engaged in evaluating, approving, structuring

or administering the Loans; provided that nothing herein shall prevent any
Lender from disclosing such information (a) to any other Lender, (b) to any
Person if reasonably incidental to the administration of the Loans, (c) upon the
order of any court or administrative agency, (d) upon the request or demand of
any regulatory agency or authority having jurisdiction over such Lender, (e)
which has been publicly disclosed other than as a result of a disclosure by such
Lender which is not otherwise permitted by this Section 13.20, (f) in connection
with any litigation to which the Administrative Agent, any Lender or their
respective Affiliates may be a party, (g) to the extent reasonably required in
connection with the exercise of any right or remedy under the Loan Documents,
(h) to such Lender's legal counsel, independent auditors and affiliates, and (i)
to any actual or proposed participant or Assignee of all or part of its rights
hereunder, so long as such actual or proposed participant or Assignee agrees to
be bound by the provisions of this Section 13.20.

         Section 13.21 WAIVER OF JURY TRIAL. TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AND EXPRESSLY
WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM
(WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO
ANY OF THE LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY OR THE
ACTIONS OF ANY LOAN PARTY, THE ADMINISTRATIVE AGENT OR ANY LENDER IN THE
NEGOTIATION, ADMINISTRATION OR ENFORCEMENT THEREOF.

         Section 13.22 Approvals and Consent. Except as may be expressly
provided to the contrary in this Agreement or in the other Loan Documents (as
applicable), in any instance under this Agreement of the other Loan Documents
where the approval, consent or exercise of judgment of the Administrative Agent
or any Lender is requested or required, (a) the granting or denial of such
approval or consent and the exercise of such judgment shall be within the sole
discretion of the Administrative Agent or such Lender, respectively, and the
Administrative Agent and such Lender shall not, for any reason or to any extent,
be required to grant such approval or consent or to exercise such judgment in
any particular manner, regardless of the reasonableness of the request or the
action or judgment of the Administrative Agent or such Lender, and (b) no
approval or consent of the Administrative Agent or any Lender shall in any event
be effective unless the same shall be in writing and the same shall be effective
only in the specific instance and for the specific purpose for which given.

         Section 13.23 Agent for Services of Process. Each of the Subsidiaries
of the Borrower hereby irrevocably designates the Borrower, whose address is
1870 Crown Drive, Dallas, Texas 75234-9416, to receive, for and on behalf of
such Person, service of process in the State of Texas, such service being hereby
acknowledged by such Person to be effective and binding service in every
respect. In the event that the Borrower resigns or ceases to serve as such
Person's agent for service of process hereunder, such Person agrees forthwith
(a) to designate another agent for service of process in Texas, and (b) to give
prompt written notice to the Administrative Agent of the name and address of
such agent. Each of the Subsidiaries of the Borrower agrees that the failure of
its agent for service of process to give any notice of any such

THIRD AMENDED AND RESTATED CREDIT AGREEMENT - Page 111
<PAGE>
service of process to such Person shall not impair or affect the validity of
such service or of any judgment based thereon. If, despite the foregoing, there
is for any reason no agent for service of process of such Person available to be
served, then such Person further irrevocably consents to the service of process
by the mailing thereof by the Administrative Agent or the Required Lenders by
registered or certified mail, postage prepaid, to such Person at its address
listed on the signature pages hereof. Nothing in this Section 13.23 shall affect
the right of the Administrative Agent or the Lenders to serve legal process in
any other manner permitted by law or affect the right of the Administrative
Agent or any Lender to bring any action or proceeding against the Borrower or
any of its Subsidiaries or its Property in the court of any jurisdiction.

         Section 13.24 Joint and Several Obligations. Each and every
representation, warranty, covenant or agreement of the Loan Parties or any two
or more Loan Parties or of the Borrower and its Subsidiaries contained herein
shall be, and shall be deemed to be, the joint and several representation,
warranty, covenant and agreement of each of the Loan Parties or such Loan
Parties or of the Borrower and each of its Subsidiaries, respectively, and of
all such Persons.

         Section 13.25 Amendment and Restatement of Existing Agreement.
Effective as of the Closing Date and upon the effectiveness of this Agreement,
this Agreement shall constitute an amendment and restatement of, but not an
extinguishment of the Obligations (as defined in the Existing Agreement)
outstanding under, the Existing Agreement in its entirety; provided, however,
that the Existing Agreement shall remain in full force and effect unless and
until such amendment and restatement occurs.

         Section 13.26 Assignments and Assumptions. The Lenders hereby agree
among themselves (and each of the Borrower and its Subsidiaries hereby consents
to such agreement) that, concurrently with the Closing Date, there shall be
deemed to have occurred assignments and assumptions with respect to the
Commitments, Loans and Letters of Credit and rights and obligations relating
thereto under this Agreement and the other Loan Documents such that, after
giving effect to such assignments and assumptions, the Commitments and the
outstanding Loans and Letters of Credit of each of the Lenders are as stated in
this Agreement, and the Lenders hereby make such assignments and assumptions.
The Lenders shall make all appropriate payments and adjustments among themselves
to effectuate the appropriate purchase price for and other amounts payable with
respect to such assignments and assumptions. Without limiting the generality of
the foregoing, the Lenders and the Borrower hereby acknowledge and agree that
the increased Commitment, Loans and Letters of Credit held or participated in by
Bank One, NA as reflected in the Agreement have resulted in a corresponding
decrease in the Commitments, Loans and Letters of Credit held or participated in
by Fleet National Bank and Bank Austria Creditanstalt Corporate Finance, Inc.,
as reflected in this Agreement.

         Section 13.27 Syndication Agent. Bank One, NA shall have no duties,
liabilities or obligations under the Loan Documents as a result of, or in its
capacity as, Syndication Agent. Without limiting the generality of the
foregoing, the Syndication Agent shall not have or be deemed to have any
fiduciary relationship with any Lender or any other party to the Loan Documents.

         Bank's ability to consent to any departure by the Borrower therefrom
         without the approval of the participant, except that the approval of

         Advances or any fees or other amounts payable hereunder, in each case
         to the extent subject to such participation, or postpone any date fixed
         for any payment of principal of, or interest on, the Advances or any
         fees or other amounts payable hereunder, in each case to the extent
         subject to such participation.

                  (f) Notwithstanding any other provisions set forth in this
         Agreement, any Bank may at any time create a security interest in all

the Credit Agreement and any other documents executed pursuant thereto, with a
Commitment in the amount shown on Schedule IV to this Amendment. Each New Bank
agrees that (i) none of the Agent, the Co-Syndication Agents, the
Co-Documentation Agents, the Arranger or any Bank has made any representation or
warranty or assumed any responsibility with respect to any statements,
warranties or representations, whether written or oral, made in or in connection

connection therewith; (iii) such New Bank confirms that it has received a copy
of the Credit Agreement, together with copies of the financial statements and
such other documents and information as it has deemed appropriate to make its
own credit analysis and decision to enter into the Credit Agreement; (iv) such
New Bank will, independently and without reliance upon the Agent, or any Bank
and based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in taking or not taking action
under the Credit Agreement, any Note or Notes or any other instrument or
document; (v) such New Bank appoints and authorizes the Agent to act as Agent on

their terms all of the obligations which by the terms of the Credit Agreement,
any Note or Notes or any other instrument or document furnished pursuant to the
Credit Agreement are required to be performed by it as a Bank.

         After giving effect to this Amendment, the Commitment of each Bank
shall be as shown on Schedule IV hereto, effective as of July 24, 2001 and the
aggregate total of all such Commitments is $2,200,000,000.

         SECTION 16. Extension of Stated Termination Date. Pursuant to Section
2.18 of the Credit Agreement, each of the Banks executing below agrees that the
Stated Termination Date shall be extended to July 23, 2002.

         SECTION 17. Replacement of Documentation Agent. Each Bank hereby
designates each of B of A and Credit Lyonnais as a Co-Documentation Agent and B
of A and Credit Lyonnais hereby accept such designation. Each of the
Co-Documentation Agents and the Banks agrees that the Co-Documentation Agents
shall replace the Documentation Agent for all purposes related to the Credit
Agreement, the Notes and any other instrument or document related thereto. Each
reference to the Documentation Agent in the Credit Agreement (including in the
preface, recitals and any schedule or exhibit), any Note or any other document
or

                                       10

instrument related to the Credit Agreement shall be deemed to be a reference to
the Co-Documentation Agents.

         SECTION 18. Limited Waiver of Section 5.2(e). The Borrower has
requested the waiver of, and each Bank by its signature hereby agrees to waive,
Section 5.2(e) of the Credit Agreement for and in connection with the following:

                  (a) WCG and/or one or more of the Subsidiaries thereof owns
the assets described on Annex A hereto. TWC anticipates that it or one of its
Subsidiaries may enter into a Sale and Lease-Back Transaction in which TWC or
one of its Subsidiaries will purchase the assets described on Annex A and then
lease such assets to WCG or a WCG Subsidiary. TWC hereby covenants that such
transaction shall be entered into on terms and conditions reasonably fair in all
material respects to TWC and its Subsidiaries. To the extent that such Sale and
Lease-Back Transaction may be, or may be deemed to be, an investment in a WCG
Subsidiary, an advance to a WCG Subsidiary, or a purchase, acquisition or
ownership of an obligation of a WCG Subsidiary, such transaction is prohibited
by Section 5.2(e) of the Credit Agreement.

         In connection with such Sale and Lease-Back Transaction, and only for
purposes of such transactions, TWC requests that the Banks waive the provisions
of Section 5.2(e) of the Credit Agreement to allow TWC and/or its Subsidiaries
to effect the Sale and Lease-Back Transaction, described in the preceding
paragraph. Nothing herein shall, or shall be deemed to, waive the provisions of
Section 5.2(j) of the Credit Agreement, or any other provisions of the Credit
Agreement applicable to the Sale and Lease-Back Transaction, except as expressly
set forth above with respect to Section 5.2(e) thereof.

         By its signature hereto, each Bank agrees to waive and does hereby
waive Section 5.2(e) (and only Section 5.2(e)) of the Credit Agreement to allow,
and only to the extent necessary to allow, TWC and its Subsidiaries to acquire
the assets described on Annex A and to act as lessor pursuant to the Sale and
Lease-Back Transaction described above involving such assets.

         SECTION 19. Representations and Warranties. To induce the Agent and the
Banks to enter into this Amendment, the Borrower hereby reaffirms, as of the
date hereof, its representations and warranties contained in Article IV of the
Credit Agreement (except to the extent such representations and warranties
relate solely to an earlier date) and additionally represents and warrants as
follows:

                  (a) The Borrower is duly organized, validly existing and in
good standing under the laws of the State of Delaware and has all corporate or
limited liability company powers and all governmental licenses, authorizations,
certificates, consents and approvals required to carry on its business as now
conducted in all material respects, except for those licenses, authorizations,
certificates, consents and approvals which the failure to have could not
reasonably be expected to have a material adverse effect on the business,
assets, condition or operation of the Borrower and its Subsidiaries taken as a
whole. Each material Subsidiary of the Borrower is duly organized or validly
formed, validly existing and (if applicable) in good standing under the laws of
its jurisdiction of incorporation or formation, except where the failure to be
so organized, existing and in good standing could not reasonably be expected to
have a material adverse effect on the business, assets, condition or operations
of the Borrower and its

                                       11
<PAGE>

Subsidiaries taken as a whole. Each material Subsidiary of the Borrower has all
corporate or limited liability company powers and all governmental licenses,
authorizations, certificates, consents and approvals required to carry on its
business as now conducted in all material respects, except for those licenses,
authorizations, certificates, consents and approvals which the failure to have
could not reasonably be expected to have a material adverse effect on the
business, assets, condition or operation of the Borrower and its Subsidiaries
taken as a whole.

                  (b) The execution, delivery and performance by the Borrower of
this Amendment and the consummation of the transactions contemplated by this
Amendment are within the Borrower's corporate powers, have been duly authorized
by all necessary corporate action, do not contravene (i) the Borrower's charter
or by-laws or (ii) any law or any contractual restriction binding on or
affecting the Borrower and will not result in or require the creation or
imposition of any Lien.

                  (c) No authorization or approval or other action by, and no
notice to or filing with, any governmental authority or regulatory body is
required for the due execution, delivery and performance by the Borrower of this
Amendment or the consummation of the transactions contemplated by this
Amendment.

                  (d) This Amendment has been duly executed and delivered by the
Borrower. This Amendment and the Credit Agreement as amended by this Amendment
are the legal, valid and binding obligations of the Borrower enforceable against
the Borrower in accordance with its terms, except as such enforceability may be
limited by any applicable bankruptcy, insolvency, reorganization, moratorium or
similar law affecting creditors' rights generally and by general principles of
equity.

                  (e) Except as set forth in the Public Filings, there is, as to
the Borrower, no pending or, to the knowledge of the Borrower, threatened action
or proceeding affecting the Borrower or any material Subsidiary of the Borrower
before any court, governmental agency or arbitrator, which could reasonably be
expected to materially and adversely affect the financial condition or
operations of the Borrower and its Subsidiaries taken as a whole or which
purports to affect the legality, validity, binding effect or enforceability of
this Amendment, the Credit Agreement or any Note. For the purposes of this
Section, "Public Filings" shall mean the Borrower's annual report on Form 10-K
for the year ended December 31, 2000, and the Borrower's quarterly reports on
Form 10-Q for the quarter ended March 31, 2001.

                  (f) Upon giving effect to this Amendment, no event has
occurred and is continuing which constitutes an Event of Default or which would
constitute an Event of Default but for the requirement that notice be given or
time elapse or both.

         SECTION 20. Conditions to Effectiveness. The effectiveness of this
Amendment is conditioned upon receipt by the Agent of all the following
documents, each in form and substance satisfactory to the Agent:

                  (a) Counterparts of this Amendment executed by the Borrower,
the Agent and each of the Banks;

(ii) the resolutions of the Borrower authorizing the execution of this Amendment
and (iii) the names and true signatures of the officers authorized to execute

requested.

         SECTION 21. Effect. This Amendment shall be deemed to be an amendment
to the Credit Agreement, and the Credit Agreement, as amended hereby, is hereby
ratified, approved and confirmed in each and every respect. All references to
the Credit Agreement in any other document, instrument, agreement or writing
shall hereafter be deemed to refer to the Credit Agreement as amended hereby.

         SECTION 22. Governing Law, Etc. THIS AMENDMENT SHALL BE A CONTRACT MADE
UNDER AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK. Whenever
possible each provision of this Amendment shall be interpreted in such manner as
to be effective and valid under applicable law, but if any provision of this
Amendment shall be prohibited by or invalid under applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
Amendment.

         SECTION 23. Counterpart Execution. This Amendment may be executed in
any number of counterparts, all of which taken together shall constitute one and
the same instrument, and any party hereto may execute this Amendment by signing
one or more counterparts.

         SECTION 24. Successors and Assigns. This Amendment shall be binding
upon the Borrower, the Agent and the Banks and their respective successors and
assigns, and shall inure to the benefit of each of the Borrower, the Agent and
the Banks and the successors and assigns of the Banks.
