continue as a Eurodollar Advance until the end of the then applicable Interest
Period therefor, at which time such Eurodollar Advance shall be automatically

was repaid in accordance with Section 2.7 or (y) the Parent Borrower or, with
respect to the Revolving Subfacility only, the Subsidiary Borrower, shall have
given the Administrative Agent a Conversion/Continuation Notice (as defined

give the Administrative Agent irrevocable


                                      -19-

   27



notice (a "Conversion/Continuation Notice") of each conversion of a Floating
Rate Advance into a Eurodollar Advance or continuation of a Eurodollar Advance
not later than 10:00 a.m. (Dallas time) at least three Business Days prior to
the date of the requested conversion or continuation, specifying:

                  (i) the requested date, which shall be a Business Day, of such
         conversion or continuation,

                  (ii) the aggregate amount and Type of the Advance which is to
         be converted or continued, and

         Period applicable thereto.

bear interest on the outstanding principal amount thereof, for each day from and
including the date such Advance is made or is automatically converted from a
Eurodollar Advance into a Floating Rate Advance pursuant to Section 2.9, to but
excluding the date it is paid or is converted into a Eurodollar Advance pursuant
to Section 2.9 hereof, at a rate per annum equal to the lesser of (a) the
Maximum Rate, or (b) the Floating Rate for such day. Changes in the rate of
interest on that portion of any Advance maintained as a Floating Rate Advance
will take effect simultaneously with each change in the Alternate Base Rate. If
at any time the Floating Rate shall exceed the Maximum Rate, thereby causing the
interest accruing on an Advance to be limited to the Maximum Rate, then any
subsequent reduction in the Floating Rate for such Advance shall not reduce the
rate of interest on such Advance below the Maximum Rate until the aggregate
amount of interest accrued on such Advance equals the aggregate amount of
interest which would have accrued on such Advance if the Floating Rate had at
all times been in effect. Each Eurodollar Advance shall bear interest on the
outstanding principal amount thereof from and including the first day of the
Interest Period applicable thereto to (but not including) the last day of such
Interest Period at the interest rate determined by the Administrative Agent as
applicable to such Eurodollar Advance based upon the Parent Borrower's or, with
respect to the Revolving Subfacility only, the Subsidiary Borrower's, selections
under Sections 2.8 and 2.9 and otherwise in accordance with the terms hereof. No
Interest Period may end after the Facility Termination Date.

         2.11. Rates Applicable After Default. Notwithstanding anything to the
contrary contained in Section 2.8 or 2.9, during the continuance of a Default or
Unmatured Default the Required Lenders may, at their option, by notice to the
Borrowers, declare that no Advance may be made as, converted into or continued
as a Eurodollar Advance. During the continuance of a Default the Required
Lenders may, at their option, by notice to the Borrowers, declare that (i) each
Eurodollar Advance shall bear interest for the remainder of the applicable
Interest Period at the rate otherwise applicable to such Interest Period (but
calculated as if the highest Applicable Margin was then in effect) plus 2% per
annum, (ii) each Floating Rate Advance shall bear interest at a rate per annum
equal to the Floating Rate in effect from time to time (but calculated as if the
highest Applicable Margin was then in effect) plus 2% per annum and (iii) the LC
Fee shall be calculated as if the highest Applicable


                                      -20-

   28



Margin was then in effect and increased by 2% per annum, provided that, during
the continuance of a Default under Section 7.6 or 7.7, the interest rates set
forth in clauses (i) and (ii) above and the increase in the LC Fee set forth in
clause (iii) above shall be applicable to all Credit Extensions without any
election or action on the part of the Administrative Agent or any Lender,
subject in all events to the limitations of the Maximum Rate.

         2.12. Method of Payment. All payments of the Obligations hereunder
shall be made, without setoff, deduction, or counterclaim, in immediately
available funds to the Administrative Agent at the Administrative Agent's
address specified pursuant to Article XIII, or at any other Lending Installation
of the Administrative Agent specified in writing by the Administrative Agent to
the Borrowers, by noon (local time) on the date when due and shall (except in

indemnified by the Lenders, or as otherwise specifically required hereunder) be
applied ratably by the Administrative Agent among the Lenders. Each payment
delivered to the Administrative Agent for the account of any Lender shall be
delivered promptly by the Administrative Agent to such Lender in the same type
of funds that the Administrative Agent received at its address specified
pursuant to Article XIII or at any Lending Installation specified in a notice
received by the Administrative Agent from such Lender. The Administrative Agent
is hereby authorized to charge the account of the Parent Borrower and, with
respect to the Revolving Subfacility only, the Subsidiary Borrower, maintained
with Bank One for each payment of principal, interest, Reimbursement Obligations
and fees as it becomes due hereunder. Each reference to the Administrative Agent
in this Section 2.12 shall also be deemed to refer, and shall apply equally, to
the LC Issuer, in the case of payments required to be made by the Parent
Borrower to the LC Issuer pursuant to Section 2.19.6.

         2.13. Noteless Agreement; Evidence of Indebtedness.

                  (i) Each Lender shall maintain in accordance with its usual
         practice an account or accounts evidencing the indebtedness of the

         and payable from the Borrowers to each Lender hereunder, (c) the

                  (iii) The entries maintained in the accounts maintained
         pursuant to paragraphs (i) and (ii) above shall be prima facie evidence
         of the existence and amounts of the Obligations therein recorded;
         provided, however, that the failure of the Administrative Agent or any
         Lender to


                                      -21-

   29



         maintain such accounts or any error therein shall not in any manner
         affect the obligation of the Borrowers to repay the Obligations in
         accordance with their terms.

                  (iv) Any Lender may request that its Loans under the Revolving
         Credit Facility be evidenced by a promissory note in substantially the
         form of Exhibit E (a "Note"). In such event, the Parent Borrower and,
         with respect to the Revolving Subfacility only, the Subsidiary
         Borrower, shall prepare, execute and deliver to such Lender a Note
         payable to the order of such Lender in a form supplied by the
         Administrative Agent. Thereafter, the Loans evidenced by such Note and
         interest thereon shall at all times (including after any assignment
         pursuant to Section 12.3) be represented by one or more Notes payable
         to the order of the payee named therein or any assignee pursuant to
         Section 12.3, except to the extent that any such Lender or assignee
         subsequently returns any such Note for cancellation and requests that
         such Loans once again be evidenced as described in clauses (i) and (ii)
         above.

         2.14. Telephonic Notices. Each of the Parent Borrower and, with respect
to the Revolving Subfacility only, the Subsidiary Borrower, hereby authorizes
the Lenders and the Administrative Agent to extend, convert or continue
Advances, effect selections of Types of Advances and to transfer funds based on
telephonic notices made by any person or persons the Administrative Agent or any
Lender in good faith believes to be acting on behalf of the Borrowers, it being
understood that the foregoing authorization is specifically intended to allow
Borrowing Notices and Conversion/Continuation Notices to be given
telephonically. Each Borrower agrees to deliver promptly to the Administrative
Agent a written confirmation, if such confirmation is requested by the
Administrative Agent or any Lender, of each telephonic notice signed by an
Authorized Officer. If the written confirmation differs in any material respect
from the action taken by the Administrative Agent and the Lenders, the records
of the Administrative Agent and the Lenders shall govern absent manifest error.

         2.15. Interest Payment Dates; Interest and Fee Basis. Interest accrued
on each Floating Rate Advance shall be payable on each Payment Date, commencing
with the first such date to occur after the date hereof and at maturity.
Interest accrued on each Eurodollar Advance shall be payable on the last day of
its applicable Interest Period, on any date on which the Eurodollar Advance is
prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued
on each Eurodollar Advance having an Interest Period longer than three months
shall also be payable on the last day of each three-month interval during such
Interest Period. Interest, commitment fees and LC Fees shall be calculated for
actual days elapsed on the basis of a 360-day year. Interest shall be payable
for the day an Advance is made but not for the day of any payment on the amount
paid if payment is received prior to noon (local time) at the place of payment.
If any payment of principal of or interest on an Advance shall become due on a
day which is not a Business Day, such payment shall be made on the next
succeeding Business Day and, in the case of a principal payment, such extension
of time shall be included in computing interest in connection with such payment.

         2.16. Notification of Advances, Interest Rates, Prepayments and
Commitment Reductions. Promptly after receipt thereof, the Administrative Agent
will notify each Lender of the contents of each Aggregate Commitment reduction
notice, Borrowing Notice, Conversion/Continuation Notice, and


                                      -22-

   30



repayment notice received by it hereunder. Promptly after notice from the LC
Issuer, the Administrative Agent will notify each Lender of the contents of each
request for issuance of a Facility LC hereunder. The Administrative Agent will
notify each Lender of the interest rate applicable to each Eurodollar Advance
promptly upon determination of such interest rate and will give each Lender
prompt notice of each change in the Alternate Base Rate.

         2.17. Lending Installations. Each Lender may book its Loans and its
participation in any LC Obligations and the LC Issuer may book the Facility LCs
at any Lending Installation selected by such Lender or the LC Issuer, as the
case may be, and may change its Lending Installation from time to time. All
terms of this Agreement shall apply to any such Lending Installation and the
Loans, Facility LCs, participations in LC Obligations and any Notes issued
hereunder shall be deemed held by each Lender or the LC Issuer, as the case may
be, for the benefit of any such Lending Installation. Each Lender and the LC
Issuer may, by written notice to the Administrative Agent and the Borrowers in
accordance with Article XIII, designate replacement or additional Lending
Installations through which Loans will be made by it or Facility LCs will be
issued by it and for whose account Loan payments or payments with respect to
Facility LCs are to be made.

         2.18. Non-Receipt of Funds by the Administrative Agent. Unless the
Borrowers or a Lender, as the case may be, notifies the Administrative Agent
prior to the date on which it is scheduled to make payment to the Administrative
Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case
of either Borrower, a payment of principal, interest or fees to the
Administrative Agent for the account of the Lenders, that it does not intend to
make such payment, the Administrative Agent may assume that such payment has
been made. The Administrative Agent may, but shall not be obligated to, make the
amount of such payment available to the intended recipient in reliance upon such
assumption. If such Lender or Borrower, as the case may be, has not in fact made
such payment to the Administrative Agent, the recipient of such payment shall,
on demand by the Administrative Agent, repay to the Administrative Agent the
amount so made available together with interest thereon in respect of each day
during 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 (x) in the case of payment by a Lender, the
Federal Funds Effective Rate for such day for the first three days and,
thereafter, the interest rate applicable to the relevant Loan or (y) in the case
of payment by the Borrowers, the interest rate applicable to the relevant Loan.

         2.19. Facility LCs.

                  2.19.1. Issuance. Subject to the terms and conditions of this
         Agreement, the LC Issuer agrees to keep outstanding on and after the
         date hereof the standby letters of credit for the account of the Parent
         Borrower which were issued by the LC Issuer and which are further
         described on Schedule 3 (collectively, the "Existing Facility LCs").
         Each Existing Facility LC shall constitute a Facility LC for all
         purposes of this Agreement. For purposes hereof, the Existing Facility
         LCs are deemed to be issued on the date hereof. Furthermore, the LC
         Issuer hereby agrees, on the terms and conditions set forth in this
         Agreement, to issue standby and commercial letters of credit (each, a
         "Facility LC") and to renew, extend, increase, decrease or otherwise
         modify each Facility


                                      -23-

   31



         LC ("Modify," and each such action a "Modification"), from time to time
         from and including the date of this Agreement and prior to the Facility
         Termination Date upon the request of the Parent Borrower; provided that
         immediately after each such Facility LC is issued or Modified, (i) the
         aggregate amount of the outstanding LC Obligations shall not exceed
         $15,000,000 and (ii) the Aggregate Outstanding Credit Exposure shall
         not exceed the Aggregate Commitment. No Facility LC shall have an
         expiry date later than the earlier of (x) the fifth Business Day prior
         to the Facility Termination Date and (y) one year after its issuance.

                  2.19.2. Participations. Upon the issuance or Modification by
         the LC Issuer of a Facility LC in accordance with this Section 2.19,
         the LC Issuer shall be deemed, without further action by any party
         hereto, to have unconditionally and irrevocably sold to each Lender,
         and each Lender shall be deemed, without further action by any party
         hereto, to have unconditionally and irrevocably purchased from the LC
         Issuer, a participation in such Facility LC (and each Modification
         thereof) and the related LC Obligations in proportion to its Pro Rata
         Share.

                  2.19.3. Notice. Subject to Section 2.19.1, the Parent Borrower
         shall give the LC Issuer notice prior to 10:00 a.m. (Dallas time) at
         least five Business Days prior to the proposed date of issuance or
         Modification of each Facility LC, specifying the beneficiary, the
         proposed date of issuance (or Modification) and the expiry date of such
         Facility LC, and describing the proposed terms of such Facility LC and
         the nature of the transactions proposed to be supported thereby. Upon
         receipt of such notice, the LC Issuer shall promptly notify the
         Administrative Agent, and the Administrative Agent shall promptly
         notify each Lender, of the contents thereof and of the amount of such
         Lender's participation in such proposed Facility LC. The issuance or
         Modification by the LC Issuer of any Facility LC shall, in addition to
         the conditions precedent set forth in Article IV (the satisfaction of
         which the LC Issuer shall have no duty to ascertain), be subject to the
         conditions precedent that such Facility LC shall be reasonably
         satisfactory to the LC Issuer and that the Parent Borrower shall have
         executed and delivered such application agreement and/or such other
         instruments and agreements relating to such Facility LC as the LC
         Issuer shall have reasonably requested (each, a "Facility LC
         Application"). In the event of any conflict between the terms of this
         Agreement and the terms of any Facility LC Application, the terms of
         this Agreement shall control.

                  2.19.4. LC Fees. The Parent Borrower shall pay to the
         Administrative Agent, for the account of the Lenders ratably in
         accordance with their respective Pro Rata Shares, (i) with respect to
         each standby Facility LC, a letter of credit fee at a per annum rate
         equal to the Applicable Margin for Eurodollar Loans in effect from time
         to time on the average daily undrawn stated amount under such standby
         Facility LC, such fee to be payable in arrears on each Payment Date,
         and (ii) with respect to each commercial Facility LC, a one-time letter
         of credit fee in an amount equal to 0.125% of the initial stated amount
         (or, with respect to a Modification of any such commercial Facility LC
         which increases the stated amount thereof, such increase in the stated
         amount) thereof, such fee to be payable on the date of such issuance or
         increase (each such fee described in this sentence an "LC Fee"). The
         Parent Borrower shall also pay to the LC Issuer for its own account (x)
         at the time of issuance of each Facility LC, a fronting fee in an
         amount to be


                                      -24-

   32



         agreed upon between the LC Issuer and the Parent Borrower, and (y)
         documentary and processing charges in connection with the issuance or
         Modification of and draws under Facility LCs in accordance with the LC
         Issuer's standard schedule for such charges as in effect from time to
         time.

                  2.19.5. Administration; Reimbursement by Lenders. Upon receipt
         from the beneficiary of any Facility LC of any demand for payment under
         such Facility LC, the LC Issuer shall notify the Administrative Agent
         and the Administrative Agent shall promptly notify the Parent Borrower
         and each other Lender as to the amount to be paid by the LC Issuer as a
         result of such demand and the proposed payment date (the "LC Payment
         Date"). The responsibility of the LC Issuer to the Parent Borrower and
         each Lender shall be only to determine that the documents (including
         each demand for payment) delivered under each Facility LC in connection
         with such presentment shall be in conformity in all material respects
         with such Facility LC. The LC Issuer shall endeavor to exercise the
         same care in the issuance and administration of the Facility LCs as it
         does with respect to letters of credit in which no participations are
         granted, it being understood that in the absence of any gross
         negligence or willful misconduct by the LC Issuer, each Lender shall be
         unconditionally and irrevocably liable without regard to the occurrence
         of any Default or any condition precedent whatsoever, to reimburse the
         LC Issuer on demand for (i) such Lender's Pro Rata Share of the amount
         of each payment made by the LC Issuer under each Facility LC to the
         extent such amount is not reimbursed by the Parent Borrower pursuant to
         Section 2.19.6 below, plus (ii) interest on the foregoing amount to be
         reimbursed by such Lender, for each day from the date of the LC
         Issuer's demand for such reimbursement (or, if such demand is made
         after 11:00 a.m. (Dallas time) on such date, from the next succeeding
         Business Day) to the date on which such Lender pays the amount to be
         reimbursed by it, at a rate of interest per annum equal to the Federal
         Funds Effective Rate for the first three days and, thereafter, at a
         rate of interest equal to the rate applicable to Floating Rate
         Advances.

                  2.19.6. Reimbursement by Parent Borrower. The Parent Borrower
         shall be irrevocably and unconditionally obligated to reimburse the LC
         Issuer on or before the applicable LC Payment Date for any amounts to
         be paid by the LC Issuer upon any drawing under any Facility LC,
         without presentment, demand, protest or other formalities of any kind;
         provided that neither the Parent Borrower nor any Lender shall hereby
         be precluded from asserting any claim for direct (but not
         consequential) damages suffered by the Parent Borrower or such Lender
         to the extent, but only to the extent, caused by (i) the willful
         misconduct or gross negligence of the LC Issuer in determining whether
         a request presented under any Facility LC issued by it complied with
         the terms of such Facility LC or (ii) the LC Issuer's failure to pay
         under any Facility LC issued by it after the presentation to it of a
         request strictly complying with the terms and conditions of such
         Facility LC. All such amounts paid by the LC Issuer and remaining
         unpaid by the Parent Borrower shall bear interest, payable on demand,
         for each day until paid at a rate per annum equal to (x) the rate
         applicable to Floating Rate Advances for such day if such day falls on
         or before the applicable LC Payment Date and (y) the sum of 2% plus the
         rate applicable to Floating Rate Advances for such day if such day
         falls after such LC Payment Date. The LC Issuer will pay to each Lender
         ratably in accordance with its Pro Rata Share all amounts received by
         it from the


                                      -25-

   33



         Parent Borrower for application in payment, in whole or in part, of the
         Reimbursement Obligation in respect of any Facility LC issued by the LC
         Issuer, but only to the extent such Lender has made payment to the LC
         Issuer in respect of such Facility LC pursuant to Section 2.19.5.
         Subject to the terms and conditions of this Agreement (including
         without limitation the submission of a Borrowing Notice in compliance
         with Section 2.8 and the satisfaction of the applicable conditions
         precedent set forth in Article IV), the Parent Borrower may request an
         Advance hereunder for the purpose of satisfying any Reimbursement
         Obligation.

                  2.19.7. Obligations Absolute. The Parent Borrower's
         obligations under this Section 2.19 shall be absolute and unconditional
         under any and all circumstances and irrespective of any setoff,
         counterclaim or defense to payment which the Parent Borrower may have
         or have had against the LC Issuer, any Lender or any beneficiary of a
         Facility LC. The Parent Borrower further agrees with the LC Issuer and
         the Lenders that the LC Issuer and the Lenders shall not be responsible
         for, and the Parent Borrower's Reimbursement Obligation in respect of
         any Facility LC shall not be affected by, among other things, the
         validity or genuineness of documents or of any endorsements thereon,
         even if such documents should in fact prove to be in any or all
         respects invalid, fraudulent or forged, or any dispute between or among
         the Parent Borrower, any of its Affiliates, the beneficiary of any
         Facility LC or any financing institution or other party to whom any
         Facility LC may be transferred or any claims or defenses whatsoever of
         the Parent Borrower or of any of its Affiliates against the beneficiary
         of any Facility LC or any such transferee. The LC Issuer shall not be
         liable for any error, omission, interruption or delay in transmission,
         dispatch or delivery of any message or advice, however transmitted, in
         connection with any Facility LC. The Parent Borrower agrees that any
         action taken or omitted by the LC Issuer or any Lender under or in
         connection with each Facility LC and the related drafts and documents,
         if done without gross negligence, bad faith or willful misconduct,
         shall be binding upon the Parent Borrower and shall not put the LC
         Issuer or any Lender under any liability to the Parent Borrower.
         Nothing in this Section 2.19.7 is intended to limit the right of the
         Parent Borrower to make a claim against the LC Issuer for damages as
         contemplated by the proviso to the first sentence of Section 2.19.6.

                  2.19.8. Actions of LC Issuer. The LC Issuer shall be entitled
         to rely, and shall be fully protected in relying, upon any Facility LC,
         draft, writing, resolution, notice, consent, certificate, affidavit,
         letter, cablegram, telegram, telecopy, telex or teletype message,
         statement, order or other document reasonably believed by it to be
         genuine and correct and to have been signed, sent or made by the proper
         Person or Persons, and upon advice and statements of legal counsel,
         independent accountants and other experts selected by the LC Issuer.
         The LC Issuer shall be fully justified in failing or refusing to take
         any action under this Agreement unless it shall first have received
         such advice or concurrence of the Required Lenders as it reasonably
         deems appropriate or it shall first be indemnified to its reasonable
         satisfaction by the Lenders against any and all liability and expense
         which may be incurred by it by reason of taking or continuing to take
         any such action. Notwithstanding any other provision of this Section
         2.19, the LC Issuer shall in all cases be fully protected in acting, or
         in refraining from acting, under this Agreement in accordance with a
         request of the Required Lenders, and such request and any action taken
         or failure to act


                                      -26-

   34



         pursuant thereto shall be binding upon the Lenders and any future
         holders of a participation in any Facility LC.

                  2.19.9. Indemnification. The Parent Borrower hereby agrees to
         indemnify and hold harmless each Lender, the LC Issuer and the
         Administrative Agent, and their respective directors, officers, agents
         and employees from and against any and all claims and damages, losses,
         liabilities, costs or expenses (including reasonable attorneys' fees
         and disbursements) which such Lender, the LC Issuer or the
         Administrative Agent may incur (or which may be claimed against such
         Lender, the LC Issuer or the Administrative Agent by any Person
         whatsoever) by reason of or in connection with the issuance, execution
         and delivery or transfer of or payment or failure to pay under any
         Facility LC or any actual or proposed use of any Facility LC,
         including, without limitation, any claims, damages, losses,
         liabilities, costs or expenses which the LC Issuer may incur by reason
         of or in connection with (i) the failure of any other Lender to fulfill
         or comply with its obligations to the LC Issuer hereunder (but nothing
         herein contained shall affect any rights the Parent Borrower may have
         against any defaulting Lender) or (ii) by reason of or on account of
         the LC Issuer issuing any Facility LC which specifies that the term
         "Beneficiary" included therein includes any successor by operation of
         law of the named Beneficiary, but which Facility LC does not require
         that any drawing by any such successor Beneficiary be accompanied by a
         copy of a legal document, satisfactory to the LC Issuer, evidencing the
         appointment of such successor Beneficiary; provided that the Parent
         Borrower shall not be required to indemnify any Lender, the LC Issuer
         or the Administrative Agent or any director, officer, agent or employee
         thereof for any claims, damages, losses, liabilities, costs or expenses
         to the extent, but only to the extent, caused by (x) the willful
         misconduct, bad faith or gross negligence of the LC Issuer in
         determining whether a request presented under any Facility LC complied
         with the terms of such Facility LC or (y) the LC Issuer's failure to
         pay under any Facility LC after the presentation to it of a request
         strictly complying with the terms and conditions of such Facility LC.
         Nothing in this Section 2.19.9 is intended to limit the obligations of
         the Parent Borrower under any other provision of this Agreement.

                  2.19.10. Lenders' Indemnification. Each Lender shall, ratably
         in accordance with its Pro Rata Share, indemnify the LC Issuer, its
         Affiliates and their respective directors, officers, agents and
         employees (to the extent not reimbursed by the Parent Borrower) against
         any cost, expense (including reasonable counsel fees and
         disbursements), claim, demand, action, loss or liability (except such
         as result from such indemnitees' gross negligence or willful misconduct
         or the LC Issuer's failure to pay under any Facility LC after the
         presentation to it of a request strictly complying with the terms and
         conditions of the Facility LC) that such indemnitees may suffer or
         incur in connection with this Section 2.19 or any action taken or
         omitted by such indemnitees hereunder.

                  2.19.11. Facility LC Collateral Account. The Parent Borrower
         agrees that it will, after the occurrence of a Default and upon the
         request of the Administrative Agent or the Required Lenders and until
         the final expiration date of any Facility LC and thereafter as long as
         any amount is payable to the LC Issuer or the Lenders in respect of any
         Facility LC, maintain a special


                                      -27-

   35



         collateral account pursuant to arrangements satisfactory to the
         Administrative Agent (the "Facility LC Collateral Account") at the
         Administrative Agent's office at the address specified pursuant to
         Article XIII, in the name of such Parent Borrower but under the sole
         dominion and control of the Administrative Agent, for the benefit of
         the Lenders and in which such Parent Borrower shall have no interest
         other than as set forth in Section 8.1. The Parent Borrower hereby
         pledges, assigns and grants to the Administrative Agent, on behalf of
         and for the ratable benefit of the Lenders and the LC Issuer, a
         security interest in all of the Parent Borrower's right, title and
         interest in and to all funds which may from time to time be on deposit
         in the Facility LC Collateral Account to secure the prompt and complete
         payment and performance of the Obligations. The Administrative Agent
         will invest any funds on deposit from time to time in the Facility LC
         Collateral Account in certificates of deposit of Bank One having a
         maturity not exceeding 30 days. Nothing in this Section 2.19.11 shall
         either obligate the Administrative Agent to require the Parent Borrower
         to deposit any funds in the Facility LC Collateral Account or limit the
         right of the Administrative Agent to release any funds held in the
         Facility LC Collateral Account in each case other than as required by
         Section 8.1.

                  2.19.12. Rights as a Lender. In its capacity as a Lender, the
         LC Issuer shall have the same rights and obligations as any other
         Lender.

         2.20. Replacement of Lender. If either Borrower is required pursuant to
Section 3.1, 3.2 or 3.5 to make any additional payment to any Lender or if any
Lender's obligation to make or continue, or to convert Floating Rate Advances
into, Eurodollar Advances shall be suspended pursuant to Section 3.3 (any Lender
so affected an "Affected Lender"), the Borrowers may elect, if such amounts
continue to be charged or such suspension is still effective, to replace such
Affected Lender as a Lender party to this Agreement, provided that no Default or
Unmatured Default shall have occurred and be continuing at the time of such
replacement, and provided further that, concurrently with such replacement, (i)
another bank or other entity which is reasonably satisfactory to the Borrowers
and the Administrative Agent shall agree, as of such date, to purchase for cash
the Credit Extensions and other Obligations due to the Affected Lender pursuant
to an assignment substantially in the form of Exhibit C and to become a Lender
for all purposes under this Agreement and to assume all obligations of the
Affected Lender to be terminated as of such date and to comply with the
requirements of Section 12.3 applicable to assignments, and (ii) the Borrowers
shall pay to such Affected Lender in same day funds on the day of such
replacement (A) all interest, fees and other amounts then accrued but unpaid to
such Affected Lender by the Borrowers hereunder to and including the date of
termination, including without limitation payments due to such Affected Lender
under Sections 3.1, 3.2 and 3.5, and (B) an amount, if any, equal to the payment
which would have been due to such Lender on the day of such replacement under
Section 3.4 had the Credit Extensions of such Affected Lender been prepaid on
such date rather than sold to the replacement Lender.

         2.21. Swing Line Subfacility.

                  2.21.1. Conditions. For the convenience of the parties,
         Administrative Agent, solely for its own account, may make any
         requested Advance under the Revolving Credit Facility (which request
         must be made before 1:00 p.m. (Dallas time) on the Business Day the
         Advance is to be


                                      -28-

   36



         made and may be telephonic if confirmed in writing within two Business
         Days) in the minimum amount of $100,000 (or a greater integral multiple
         of $100,000) directly to Parent Borrower as a Swing Line Advance
         without requiring each other Lender to fund its Pro Rata Share thereof
         on such Business Day. Swing Line Advances are subject to the following
         conditions:

                  (i) Each Swing Line Advance must occur on a Business Day
         before the Facility Termination Date;

                  (ii) The aggregate principal outstanding of all Swing Line
         Advances may not exceed $15,000,000; the aggregate principal
         outstanding of all Swing Line Advances, all other Advances under the
         Revolving Credit Facility, and all LC Obligations may not exceed the
         Aggregate Commitment under the Revolving Credit Facility; and no Swing
         Line Advance shall be made which would cause the aggregate principal
         outstanding of all Loans (including Swing Line Advances) made by the
         Administrative Agent under the Revolving Credit Facility to exceed the
         Administrative Agent's Commitment under the Revolving Credit Facility;

                  (iii) Each Swing Line Advance shall be paid in full by the
         Parent Borrower on the Business Day immediately succeeding the date of
         such Swing Line Advance by the funding of an Advance under the
         Revolving Credit Facility and in any event on the Facility Termination
         Date; and

                  (iv) Each Swing Line Advance shall be a Floating Rate Advance.

                  2.21.2. Lenders' Funding of Swing Line Advances as Advances
         Under Revolving Credit Facility. The Administrative Agent shall give to
         the Lenders notice of each Swing Line Advance not later than 3:00 p.m.
         (Dallas time) on the date of such Swing Line Advance, which notice
         shall, on behalf of the Parent Borrower (and for such purpose the
         Parent Borrower hereby irrevocably directs the Administrative Agent to
         act on its behalf), request each Lender to make, and each Lender hereby
         agrees to make, an Advance in an amount equal to such Lender's Pro Rata
         Share of the aggregate amount of the Swing Line Advances (the "Refunded
         Swing Line Advances") outstanding on the date of such notice, to repay
         the Administrative Agent. Each Lender shall make the amount of such
         Advance available to the Administrative Agent in immediately available
         funds, not later than noon (Dallas time) one Business Day after the
         date of such notice. The proceeds of such Advance shall be immediately
         made available to the Administrative Agent for application by the
         Administrative Agent to the repayment of the Refunded Swing Line
         Advances. The Parent Borrower irrevocably authorizes the Administrative
         Agent to charge the Parent Borrower's accounts with the Administrative
         Agent in order to immediately pay the amount of such Refunded Swing
         Line Advances to the extent amounts received from the Lenders are not
         sufficient to repay in full such Refunded Swing Line Advances (with
         notice of such charge being provided to the Parent Borrower, provided
         that the failure to give such notice shall not affect the validity of
         such charge). All such Refunded Swing Line Advances shall be subject to
         all provisions of this Agreement concerning Advances under the
         Revolving Credit Facility. If prior to the time an Advance would
         otherwise have been made pursuant to this section, Advances may not be
         made


                                      -29-

   37



         as contemplated by this section, each Lender shall irrevocably and
         unconditionally purchase and receive from Administrative Agent a
         ratable participation in such Swing Line Advance and shall make
         available to Administrative Agent in immediately available funds its
         Pro Rata Share of such unpaid amount, together with interest from the
         date when its payment was due to, but not including, the date of
         payment. If a Lender does not promptly pay its amount upon
         Administrative Agent's demand, and until such Lender makes the required
         payment, Administrative Agent is deemed to continue to have outstanding
         a Swing Line Advance in the amount of such Lender's unpaid obligation.
         Parent Borrower shall make each payment of all or any part of any Swing
         Line Advance to Administrative Agent for the ratable benefit of
         Administrative Agent and those Lenders who have funded their
         participations in Swing Line Advances under this Section (but all
         interest accruing on Swing Line Advances before the funding date of any
         Advance under the Revolving Credit Facility to repay such Swing Line
         Advance or any participation is payable solely to Administrative Agent
         for its own account).

         2.22. Revolving Subfacility.

                  (a)      From and including the date of this Agreement and
                           prior to the Facility Termination Date, each Lender
                           severally agrees, on the terms and conditions set
                           forth in this Agreement, to make Loans to the
                           Borrowers from time to time for the purposes
                           hereinafter set forth; provided that the aggregate
                           principal amount of the Loans outstanding under this
                           Section 2.22 shall not at any time exceed $10,000,000
                           (as such aggregate amount may be increased or reduced
                           from time to time, the "Revolving Subfacility
                           Limit"), and provided further that after giving
                           effect to the making of each such Loan, such Lender's
                           Outstanding Credit Exposure shall not exceed its
                           Commitment. Subject to the terms of this Agreement,
                           the Borrowers may borrow, repay, and reborrow at any
                           time prior to the Facility Termination Date amounts
                           under the Revolving Subfacility. The Borrowers hereby
                           designate Loans under the Revolving Subfacility Limit
                           as Designated Senior Debt under the Indenture.

                  (b)      Loans under this Section 2.22 may consist of Floating
                           Rate Advances or Eurodollar Advances, or a
                           combination thereof, as a Borrower may request, and
                           may be repaid and reborrowed in accordance with the
                           provisions hereof. The principal amount of all Loans
                           under the Revolving Subfacility shall be paid in full
                           by the Borrowers on the Facility Termination Date.
                           The obligation to repay the Loans under the Revolving
                           Subfacility shall be joint and several obligations of
                           the Borrowers.

         2.23. Prepayments from Sale of Assets. Concurrently with the receipt of
Net Cash Proceeds from the sale or disposition by the Parent Borrower or any
Subsidiary of any assets at any time which are permitted to be sold or disposed
of pursuant to Section 6.13 of this Agreement (other than (i) the sale of
inventory in the ordinary course of business, (ii) when no Default exists, the
sale of accounts or notes receivable described in Section 6.13(iii), and (iii)
when no Default exists, other sales or dispositions which


                                      -30-

   38



yield Net Cash Proceeds in an amount not to exceed $5,000,000 in the aggregate
during the term of this Agreement), the Parent Borrower shall prepay or cause to
be prepaid the Advances in a principal amount equal to 100% of such Net Cash
Proceeds. Notwithstanding anything to the contrary contained herein, any
prepayment required by this Section 2.23 to be applied to Eurodollar Loans may
be paid by the Parent Borrower into a segregated interest bearing account of
Parent Borrower designated by the Administrative Agent for application to the
Loans upon the last day of an Interest Period applicable thereto.

         2.24. Joint and Several Liability of the Borrowers.

                  (a) Each of the Borrowers is accepting joint and several
         liability hereunder with respect to the Joint and Several Obligations
         in consideration of the financial accommodation to be provided by the
         Lenders under Section 2.22 of this Agreement, for the mutual benefit,
         directly and indirectly, of each of the Borrowers and in consideration
         of the undertakings of each of the Borrowers to accept joint and
         several liability for the Joint and Several Obligations of each of them
         under Section 2.22.

                  (b) Each of the Borrowers jointly and severally hereby
         irrevocably and unconditionally accepts, not merely as a surety but
         also as a co-debtor, joint and several liability with the other
         Borrower with respect to the payment and performance of all of the
         Joint and Several Obligations arising under this Agreement and the
         other Loan Documents, it being the intention of the parties hereto that
         all the Joint and Several Obligations shall be the joint and several
         obligations of each of the Borrowers without preferences or distinction
         among them.

                  (c) If and to the extent that either of the Borrowers shall
         fail to make any payment with respect to any of the Joint and Several
         Obligations hereunder as and when due or to perform any of such Joint
         and Several Obligations in accordance with the terms thereof, then in
         each such event, the other Borrower will make such payment with respect
         to, or perform, such Joint and Several Obligations.

                  (d) The obligations of each Borrower under the provisions of
         this Section 2.24 constitute full recourse obligations of such
         Borrower, enforceable against it to the full extent of its properties
         and assets, irrespective of the validity, regularity or enforceability
         of this Agreement or any other circumstances whatsoever.

                  (e) Except as otherwise expressly provided herein, each
         Borrower hereby waives notice of acceptance of its joint and several
         liability, notice of occurrence of any Default or Unmatured Default
         (except to the extent notice is expressly required to be given pursuant
         to the terms of this Agreement), or of any demand for any payment under
         this Agreement, notice of any action at any time taken or omitted by
         the Administrative Agent or the Lenders under or in respect of any of
         the Joint and Several Obligations hereunder, any requirement of
         diligence and, generally, all demands, notices and other formalities of
         every kind in connection with this Agreement. Each Borrower hereby
         assents to, and waives notice of, any extension or postponement of the
         time for the payment of any of the Joint and Several Obligations
         hereunder, the acceptance of any partial


                                      -31-

   39



         payment thereon, any waiver, consent or other action or acquiescence by
         the Administrative Agent or the Lenders at any time or times in respect
         of any default by a Borrower in the performance or satisfaction of any
         term, covenant, condition or provision of this Agreement or any other
         Loan Document, any and all other indulgences whatsoever by the
         Administrative Agent or the Lenders in respect of any of the Joint and
         Several Obligations hereunder, and the taking, addition, substitution
         or release, in whole or in part, at any time or times, of any security
         for any of such Joint and Several Obligations or the addition,
         substitution or release, in whole or in part, of either Borrower.
         Without limiting the generality of the foregoing, each Borrower assents
         to any other action or delay in acting or any failure to act on the
         part of the Administrative Agent or the Lenders, including, without
         limitation, any failure strictly or diligently to assert any right or
         to pursue any remedy or to comply fully with applicable laws or
         regulations thereunder which might, but for the provisions of this
         Section 2.24, afford grounds for terminating, discharging or relieving
         such Borrower, in whole or in part, from any of its obligations under
         this Section 2.24, it being the intention of each Borrower that, so
         long as any of the Joint and Several Obligations remain unsatisfied,
         the obligations of such Borrower under this Section 2.24 shall not be
         discharged except by performance and then only to the extent of such
         performance. The obligations of each Borrower under this Section 2.24
         shall not be diminished or rendered unenforceable by any winding up,
         reorganization, arrangement, liquidation, reconstruction or similar
         proceeding with respect to any reconstruction or similar proceeding
         with respect to a Borrower or any Lender. The joint and several
         liability of the Borrowers hereunder shall continue in full force and
         effect notwithstanding any absorption, merger, amalgamation or any
         other change whatsoever in the name, membership, constitution or place
         of formation of a Borrower or any Lender.

                  (f) The provisions of this Section 2.24 are made for the
         benefit of the Administrative Agent and the Lenders and their
         respective successors and assigns, and may be enforced by any such
         Person from time to time against either of the Borrowers as often as
         occasion therefor may arise and without requirement on the part of any
         Lender first to marshal any of its claims or to exercise any of its
         rights against the other Borrower or to exhaust any remedies available
         to it against the other Borrower or to resort to any other source or
         means of obtaining payment of any of the Joint and Several Obligations
         or to elect any other remedy. The provisions of this Section 2.24 shall
         remain in effect until all the Joint and Several Obligations hereunder
         shall have been paid in full or otherwise fully satisfied. If at any
         time, any payment, or any part thereof, made in respect of any of the
         Joint and Several Obligations, is rescinded or must otherwise be
         restored or returned by the Lenders upon the insolvency, bankruptcy or
         reorganization of either of the Borrowers, or otherwise, the provisions
         of this Section 2.24 will forthwith be reinstated and in effect as
         though such payment had not been made.

                  (g) Notwithstanding any provision to the contrary contained
         herein or in any other of the Loan Documents, the obligations of
         Subsidiary Borrower hereunder shall be limited to an aggregate amount
         equal to the largest amount that would not render its obligations
         hereunder subject to avoidance under Section 548 of the Bankruptcy Code
         or any comparable provisions of any applicable state law.


                                      -32-

         2.25. Prepayments from Sales of Capital Stock. Concurrently with the
receipt of Net Cash Proceeds from the sale or disposition by Parent Borrower to
any Person of any common stock, preferred stock, warrant or other equity
interests of Parent Borrower, the Parent Borrower shall prepay Advances in a
principal amount equal to 100% of such Net Cash Proceeds; provided however, the
Parent Borrower is not required to make a prepayment under this Section 2.25 if
and to the extent that the Parent Borrower (a) issues common stock, preferred
stock, warrant or other equity interests pursuant to stock options and provides
other stock based benefit awards to the directors, officers or employees of the
Parent Borrower, its Subsidiaries or Affiliates or (b) uses such Net Cash
Proceeds solely to fund a Permitted Acquisition, so long as in each case no
Default has occurred and is continuing immediately before and immediately after
such issuance or payment. Notwithstanding anything to the contrary contained
herein, any prepayment required by this Section 2.25 to be applied to Eurodollar
Loans may be paid by the Parent Borrower into a segregated interest bearing
account of the Parent Borrower designated by the Administrative Agent for
application to the Loans upon the last day of an Interest Period applicable
thereto.


                                   ARTICLE III

                             YIELD PROTECTION; TAXES

         3.1. Yield Protection. If, on or after the date of this Agreement, the
adoption of any law or any governmental or quasi-governmental rule, regulation,
policy, guideline or directive (whether or not having the force of law), or any
change in the interpretation or administration thereof by any governmental or
quasi-governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender or
applicable Lending Installation or the LC Issuer with any request or directive
(whether or not having the force of law) of any such authority, central bank or
comparable agency:

                  (i) subjects any Lender or any applicable Lending Installation
         or the LC Issuer to any Taxes, or changes the basis of taxation of
         payments (other than with respect to Excluded Taxes) to any Lender or
         the LC Issuer in respect of its Eurodollar Loans, Facility LCs or
         participations therein, or

                  (ii) imposes or increases or deems applicable any reserve,
         assessment, insurance charge, special deposit or similar requirement
         against assets of, deposits with or for the account of, or credit
         extended by, any Lender or any applicable Lending Installation or the
         LC Issuer (other than reserves and assessments taken into account in
         determining the interest rate applicable to Eurodollar Advances), or

                  (iii) imposes any other condition the result of which is to
         increase the cost to any Lender or any applicable Lending Installation
         or the LC Issuer of making, funding or maintaining its Eurodollar
         Loans, or of issuing or participating in Facility LCs, or reduces any
         amount receivable by any Lender or any applicable Lending Installation
         or the LC Issuer in connection with its Eurodollar Loans, Facility LCs
         or participations therein, or requires any Lender or any


                                      -33-

   41



         applicable Lending Installation or the LC Issuer to make any payment
         calculated by reference to the amount of Eurodollar Loans, Facility LCs
         or participations therein held or interest or LC Fees received by it,
         by an amount deemed material by such Lender or the LC Issuer as the
         case may be,

and the result of any of the foregoing is to increase the cost to such Lender or
applicable Lending Installation or the LC Issuer, as the case may be, of making
or maintaining its Eurodollar Loans or Commitment or of issuing or participating
in Facility LCs or to reduce the return received by such Lender or applicable
Lending Installation or the LC Issuer, as the case may be, in connection with
such Eurodollar Loans, Commitment, Facility LCs or participations therein, then,
within 15 days of demand by such Lender or the LC Issuer, as the case may be,
the Borrowers shall pay such Lender or the LC Issuer, as the case may be, such
additional amount or amounts as will compensate such Lender or the LC Issuer, as
the case may be, for such increased cost or reduction in amount received.

         3.2. Changes in Capital Adequacy Regulations. If a Lender or the LC
Issuer determines the amount of capital required or expected to be maintained by
such Lender or the LC Issuer, any Lending Installation of such Lender or the LC
Issuer, or any corporation controlling such Lender or the LC Issuer is increased
as a result of a Change, then, within 15 days of demand by such Lender or the LC
Issuer, the Borrowers shall pay such Lender or the LC Issuer the amount
necessary to compensate for any shortfall in the rate of return on the portion
of such increased capital which such Lender or the LC Issuer determines is
attributable to this Agreement, its Outstanding Credit Exposure or its
Commitment to make Loans and issue or participate in Facility LCs, as the case
may be, hereunder (after taking into account such Lender's or the LC Issuer's
policies as to capital adequacy). "Change" means (i) any change after the date
of this Agreement in the Risk-Based Capital Guidelines, or (ii) any adoption of
or change in any other law, governmental or quasi-governmental rule, regulation,
policy, guideline, interpretation, or directive (whether or not having the force
of law) after the date of this Agreement which affects the amount of capital
required or expected to be maintained by any Lender or the LC Issuer or any
Lending Installation or any corporation controlling any Lender or the LC Issuer.
"Risk-Based Capital Guidelines" means (i) the risk-based capital guidelines in
effect in the United States on the date of this Agreement, including transition
rules, and (ii) the corresponding capital regulations promulgated by regulatory
authorities outside the United States implementing the July 1988 report of the
Basle Committee on Banking Regulation and Supervisory Practices Entitled
"International Convergence of Capital Measurements and Capital Standards,"
including transition rules, and any amendments to such regulations adopted prior
to the date of this Agreement.

         3.3. Availability of Types of Advances. If any Lender determines that
maintenance of its Eurodollar Loans at a suitable Lending Installation would
violate any applicable law, rule, regulation, or directive, whether or not
having the force of law, or if the Required Lenders determine that (i) deposits
of a type and maturity appropriate to match fund Eurodollar Advances are not
available or (ii) the interest rate applicable to Eurodollar Advances does not
accurately reflect the cost of making or maintaining Eurodollar Advances, then
the Administrative Agent shall suspend the availability of Eurodollar Advances
and require any affected Eurodollar Advances to be repaid or converted to
Floating Rate Advances, subject to the payment of any funding indemnification
amounts required by Section 3.4.

         3.4. Funding Indemnification. If any payment of a Eurodollar Advance
occurs on a date which is not the last day of the applicable Interest Period,
whether because of acceleration, prepayment or otherwise, or a Eurodollar
Advance is not made on the date specified by the Borrowers for any reason other
than default by the Lenders, the Borrowers will indemnify each Lender for any
loss or cost incurred by it resulting therefrom, including, without limitation,
any loss or cost in liquidating or employing deposits acquired to fund or
maintain such Eurodollar Advance.

         3.5. Taxes.

                  (i) All payments by the Borrowers to or for the account of any
         Lender, the LC Issuer or the Administrative Agent hereunder or under
         any Note or Facility LC Application shall be made free and clear of and
         without deduction for any and all Taxes. If the Borrowers shall be
         required by law to deduct any Taxes from or in respect of any sum
         payable hereunder to any Lender, the LC Issuer or the Administrative
         Agent, (a) the sum payable shall be increased as necessary so that
         after making all required deductions (including deductions applicable
         to additional sums payable under this Section 3.5) such Lender, the LC
         Issuer or the Administrative Agent (as the case may be) receives an
         amount equal to the sum it would have received had no such deductions
         been made, (b) the Borrowers shall make such deductions, (c) the
         Borrowers shall pay the full amount deducted to the relevant authority
         in accordance with applicable law and (d) the Borrowers shall furnish
         to the Administrative Agent the original copy of a receipt evidencing
         payment thereof within 30 days after such payment is made.

                  (ii) In addition, the Borrowers hereby agree to pay any
         present or future stamp or documentary taxes and any other excise or
         property taxes, charges or similar levies which arise from any payment
         made hereunder or under any Note or Facility LC Application or from the
         execution or delivery of, or otherwise with respect to, this Agreement
         or any Note or Facility LC Application ("Other Taxes").

                  (iii) Each Borrower hereby agrees to indemnify the
         Administrative Agent, the LC Issuer and each Lender for the full amount
         of Taxes or Other Taxes (including, without limitation, any Taxes or
         Other Taxes imposed on amounts payable under this Section 3.5) paid by
         the Administrative Agent, the LC Issuer or such Lender and any
         liability (including penalties, interest and expenses) arising
         therefrom or with respect thereto. Payments due under this
         indemnification shall be made within 30 days of the date the
         Administrative Agent, the LC Issuer or such Lender makes demand
         therefor pursuant to Section 3.6.

                  (iv) Each Lender that is not incorporated under the laws of
         the United States of America or a state thereof (each a "Non-U.S.
         Lender") agrees that it will, not more than ten Business Days after the
         date of this Agreement, (i) deliver to each of the Borrowers and the
         Administrative Agent two duly completed copies of United States
         Internal Revenue Service Form W-8BEN or W-8ECI, certifying in either
         case that such Lender is entitled to receive payments under this
         Agreement without deduction or withholding of any United States federal
         income taxes, and (ii) deliver to each of the Borrowers and the
         Administrative Agent a United States Internal


                                      -35-

   43



         Revenue Form W-8 or W-9, as the case may be, and certify that it is
         entitled to an exemption from United States backup withholding tax.
         Each Non-U.S. Lender further undertakes to deliver to each of the
         Borrowers and the Administrative Agent (x) renewals or additional
         copies of such form (or any successor form) on or before the date that
         such form expires or becomes obsolete, and (y) after the occurrence of
         any event requiring a change in the most recent forms so delivered by
         it, such additional forms or amendments thereto as may be reasonably
         requested by the Borrowers or the Administrative Agent. All forms or
         amendments described in the preceding sentence shall certify that such
         Lender is entitled to receive payments under this Agreement without
         deduction or withholding of any United States 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 or amendment with respect to it and such
         Lender advises the Borrowers and the Administrative Agent that it is
         not capable of receiving payments without any deduction or withholding
         of United States federal income tax.

                  (v) For any period during which a Non-U.S. Lender has failed
         to provide the Borrowers with an appropriate form pursuant to clause
         (iv), above (unless such failure is due to a change in treaty, law or
         regulation, or any change in the interpretation or administration
         thereof by any governmental authority, occurring subsequent to the date
         on which a form originally was required to be provided), such Non-U.S.
         Lender shall not be entitled to indemnification under this Section 3.5
         with respect to Taxes imposed by the United States; provided that,
         should a Non-U.S. Lender which is otherwise exempt from or subject to a
         reduced rate of withholding tax become subject to Taxes because of its
         failure to deliver a form required under clause (iv) above, the
         Borrowers shall take such steps as such Non-U.S. Lender shall
         reasonably request to assist such Non-U.S. Lender to recover such
         Taxes.

                  (vi) Any Lender that is entitled to an exemption from or
         reduction of withholding tax with respect to payments under this
         Agreement or any Note pursuant to the law of any relevant jurisdiction
         or any treaty shall deliver to the Borrowers (with a copy to the
         Administrative Agent), at the time or times prescribed by applicable
         law, such properly completed and executed documentation prescribed by
         applicable law as will permit such payments to be made without
         withholding or at a reduced rate.

                  (vii) If the U.S. Internal Revenue Service or any other
         governmental authority of the United States or any other country or any
         political subdivision thereof asserts a claim that the Administrative
         Agent did not properly withhold tax from amounts paid to or for the
         account of any Lender (because the appropriate form was not delivered
         or properly completed, because such Lender failed to notify the
         Administrative Agent of a change in circumstances which rendered its
         exemption from withholding ineffective, or for any other reason), such
         Lender shall indemnify the Administrative Agent fully for all amounts
         paid, directly or indirectly, by the Administrative Agent as tax,
         withholding therefor, or otherwise, including penalties and interest,
         and including taxes imposed by any jurisdiction on amounts payable to
         the Administrative Agent under this


                                      -36-

   44



         subsection, together with all costs and expenses related thereto
         (including attorneys fees and time charges of attorneys for the
         Administrative Agent, which attorneys may be employees of the
         Administrative Agent). The obligations of the Lenders under this
         Section 3.5(vii) shall survive the payment of the Obligations and
         termination of this Agreement.

         3.6. Lender Statements; Survival of Indemnity. To the extent reasonably
possible, each Lender shall designate an alternate Lending Installation with
respect to its Eurodollar Loans to reduce any liability of the Borrowers to such
Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of
Eurodollar Advances under Section 3.3, so long as such designation is not, in
the reasonable judgment of such Lender, disadvantageous to such Lender. Each
Lender shall deliver a written statement of such Lender to the Borrowers (with a
copy to the Administrative Agent) as to the amount due, if any, under Section
3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth in reasonable
detail the calculations upon which such Lender determined such amount and shall
be final, conclusive and binding on the Borrowers in the absence of manifest
error. Determination of amounts payable under such Sections in connection with a
Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar
Loan through the purchase of a deposit of the type and maturity corresponding to
the deposit used as a reference in determining the Eurodollar Rate applicable to
such Loan, whether in fact that is the case or not. Unless otherwise provided
herein, the amount specified in the written statement of any Lender shall be
payable within fifteen (15) days after receipt by the Parent Borrower of such
written statement. The obligations of the Borrowers under Sections 3.1, 3.2, 3.4
and 3.5 shall survive payment of the Obligations and termination of this
Agreement.

                                    ARTICLE V

                         REPRESENTATIONS AND WARRANTIES

         The Borrowers represent and warrant to the Lenders that:

         5.1. Existence and Standing. Each of the Parent Borrower and its
Subsidiaries is a corporation, partnership (in the case of Subsidiaries only) or
limited liability company (in the case of Subsidiaries only) duly and properly
incorporated or organized, as the case may be, validly existing and (to the
extent such concept applies to such entity) in good standing under the laws of
its jurisdiction of incorporation or organization is duly qualified to transact
business and is in good standing in each jurisdiction in which its business is
conducted except where the failure to be so qualified could not reasonably be
expected to have a Material Adverse Effect.

         5.2. Authorization and Validity. The Parent Borrower has the corporate
power and authority and legal right to execute and deliver the Loan Documents to
which it is a party and to perform its obligations thereunder. The execution and
delivery by the Parent Borrower of the Loan Documents to which it is a party and
the performance of its obligations thereunder have been duly authorized by
proper corporate proceedings, and the Loan Documents to which the Parent
Borrower is a party constitute legal, valid and binding obligations of the
Parent Borrower enforceable against the Parent Borrower in accordance with their
terms, except as enforceability may be limited by bankruptcy, insolvency or
similar laws affecting the enforcement of creditors' rights generally or general
principles of equity.

         5.3. No Conflict; Government Consent. Neither the execution and
delivery by the Parent Borrower of the Loan Documents to which it is a party,
nor the consummation of the transactions therein contemplated, nor compliance
with the provisions thereof will violate (i) any law, rule, regulation, order,
writ, judgment, injunction, decree or award binding on the Parent Borrower or
any of its Subsidiaries other than violations which could not individually or in
the aggregate reasonably be expected to have a Material Adverse Effect or (ii)
the Parent Borrower's or any Subsidiary's articles or certificate of
incorporation, partnership agreement, certificate of partnership, articles or
certificate of organization, by-laws, or operating or other management
agreement, as the case may be, or (iii) the provisions of any indenture,
instrument or agreement to which the Parent Borrower or any of its Subsidiaries
is a party or is subject, or by which it, or its Property, is bound, or conflict
with or constitute a default thereunder, or result in, or require, the creation
or imposition of any Lien in, of or on the Property of the Parent Borrower or a
Subsidiary pursuant to the terms of any such indenture, instrument or agreement.
No order, consent, adjudication, approval, license, authorization, or validation
of, or filing, recording or registration with, or exemption by, or other action
in respect of any governmental or public body or authority, or any subdivision
thereof, which has not been obtained by the Parent Borrower or any of its
Subsidiaries, is required to be obtained by the Parent Borrower or any of its
Subsidiaries in connection with the execution and delivery of the Loan
Documents, the borrowings under this Agreement, the payment and performance by
the Parent Borrower of the Obligations or the legality, validity, binding effect
or enforceability of any of the Loan Documents except for such orders, consents,
adjudications, approvals, licenses, authorizations or validations of, or
filings, recordings or registrations with, or exemptions by or other actions the
failure


                                      -41-

   49



to obtain or make could not individually or in the aggregate reasonably be
expected to have a Material Adverse Effect.

         5.4. Financial Statements. The September 30, 2000 consolidated
financial statements of the Parent Borrower and its Subsidiaries heretofore
delivered to the Lenders were prepared in accordance with generally accepted
accounting principles in effect on the date such statements were prepared and
fairly present the consolidated financial condition and operations of the Parent
Borrower and its Subsidiaries at such date and the consolidated results of their
operations for the period then ended.

         5.5. Material Adverse Change. Since June 30, 2000, there has been no
change in the business, Property, financial condition or results of operations
of the Parent Borrower and its Subsidiaries taken as a whole which could
reasonably be expected to have a Material Adverse Effect.

         5.6. Taxes. The Parent Borrower and its Subsidiaries have filed all
United States federal tax returns and all other tax returns which are required
to be filed and have paid all taxes due pursuant to said returns or pursuant to
any assessment received by the Parent Borrower or any of its Subsidiaries,
except such taxes, if any, as are being contested in good faith and as to which
adequate reserves have been provided in accordance with Agreement Accounting
Principles and as to which no Lien exists and except where failure to file or
pay could not individually or in the aggregate reasonably be expected to have a
Material Adverse Effect. The latest period for which the Parent Borrower and its
Subsidiaries have been examined or for which the applicable statute of
limitations has expired is the fiscal year ended March 31, 1996. No tax liens
have been filed and no claims are being asserted with respect to any such taxes
which individually or in the aggregate have a Material Adverse Effect. The
charges, accruals and reserves on the books of the Parent Borrower and its
Subsidiaries in respect of any taxes or other governmental charges are adequate.
If any of its Subsidiaries is a limited liability company, each such limited
liability company qualifies for partnership tax treatment under United States
federal tax law.

         5.7. Litigation and Contingent Obligations. There is no litigation,
arbitration, governmental investigation, proceeding or inquiry pending or, to
the knowledge of any of their officers, threatened against or affecting the
Parent Borrower or any of its Subsidiaries which could individually or in the
aggregate reasonably be expected to have a Material Adverse Effect or which
seeks to prevent, enjoin or delay the making of any Credit Extensions. Other
than any liabilities which could not individually or in the aggregate reasonably
be expected to have a Material Adverse Effect, the Parent Borrower has no
material contingent obligations not provided for or disclosed in the financial
statements referred to in Section 5.4.

         5.8. Subsidiaries. Schedule 1 contains an accurate list of all
Subsidiaries of the Parent Borrower as of the date of this Agreement, setting
forth their respective jurisdictions of organization and the percentage of their
respective capital stock or other ownership interests owned by the Parent
Borrower or other Subsidiaries. All of the issued and outstanding shares of
capital stock or other ownership interests of such Subsidiaries have been (to
the extent such concepts are relevant with respect to such ownership interests)
duly authorized and issued and are fully paid and non-assessable.

Single Employer Plans in an amount that could reasonably be expected to have a
Material Adverse Effect. Neither the Parent Borrower nor any other member of the
Controlled Group has incurred, or is reasonably expected to incur, any
withdrawal liability to Multiemployer Plans in the aggregate in an amount that
could reasonably be expected to have a Material Adverse Effect. Each Plan
complies in all material respects with all applicable requirements of law and
regulations, and no Reportable Event has occurred with respect to any Plan that
could reasonably be expected to have a Material Adverse Effect.

         5.10. Accuracy of Information. No information, exhibit or report
furnished by the Parent Borrower or any of its Subsidiaries to the
Administrative Agent or to any Lender in connection with the negotiation of, or
compliance with, the Loan Documents contained any misstatement of material fact
or omitted to state a material fact necessary to make the statements contained
therein not misleading.

         5.11. Regulation U. Margin stock (as defined in Regulation U)
constitutes less than 25% of the value of those assets of the Parent Borrower
and its Subsidiaries which are subject to any limitation on sale, pledge, or
other restriction hereunder.

         5.12. Material Agreements. Neither the Parent Borrower nor any
Subsidiary is a party to any agreement or instrument or subject to any charter
or other corporate restriction which could reasonably be expected to have a
Material Adverse Effect. Neither the Parent Borrower nor any Subsidiary is in
default in the performance, observance or fulfillment of any of the obligations,
covenants or conditions contained in (i) any agreement to which it is a party,
which default could reasonably be expected to have a Material Adverse Effect or
(ii) any agreement or instrument evidencing or governing Indebtedness which
aggregates in excess of $2,500,000.

         5.13. Compliance With Laws. The Parent Borrower and its Subsidiaries
have complied with all applicable statutes, rules, regulations, orders and
restrictions of any domestic or foreign government or any instrumentality or
agency thereof having jurisdiction over the conduct of their respective
businesses or the ownership of their respective Property except for any failure
to comply with any of the foregoing which could not reasonably be expected to
have a Material Adverse Effect.

         5.14. Ownership of Properties. Except as set forth on Schedule 2, on
the date of this Agreement, the Parent Borrower and its Subsidiaries will have
good title, free of all Liens other than those permitted by Section 6.15, to all
of the Property and assets reflected in the Parent Borrower's most recent
consolidated financial statements provided to the Administrative Agent as owned
by the Parent Borrower and its Subsidiaries.

         5.15. Plan Assets; Prohibited Transactions. The Parent Borrower is not

2510.3-101 of an employee benefit plan (as defined in Section 3(3) of ERISA)
which is subject to Title I of ERISA or any plan (within the meaning of Section
4975 of the Code), and neither the execution of this Agreement nor the making of
Credit

of Section 406 of ERISA or Section 4975 of the Code.

         5.16. Environmental Matters. In the ordinary course of its business,
the officers of the Parent Borrower consider the effect of Environmental Laws on
the business of the Parent Borrower and its Subsidiaries, in the course of which
they identify and evaluate potential risks and liabilities accruing to the
Parent Borrower due to Environmental Laws. On the basis of this consideration,
the Parent Borrower has concluded that Environmental Laws cannot reasonably be
expected to have a Material Adverse Effect. Neither the Parent Borrower nor any
Subsidiary has received any notice to the effect that its operations are not in
material compliance with any of the requirements of applicable Environmental
Laws or are the subject of any federal or state investigation evaluating whether
any remedial action is needed to respond to a release of any toxic or hazardous
waste or substance into the environment, which non-compliance or remedial action
could reasonably be expected to have a Material Adverse Effect.

         5.17. Investment Company Act. Neither the Parent Borrower nor any

Holding Company Act of 1935, as amended.

         5.20. Post-Retirement Benefits. The present value of the expected cost
of post-retirement medical and insurance benefits payable by the Parent Borrower
and its Subsidiaries to its employees and former employees, as estimated by the
Parent Borrower in accordance with procedures and assumptions reasonably
acceptable to the Required Lenders, does not exceed $2,500,000.

         5.21. Solvency.

                  (i) Immediately after the consummation of the transactions to
         occur on the date hereof and immediately following the making of each
         Credit Extension, if any, made on the date hereof and after giving
         effect to the application of the proceeds of such Credit Extension, (a)
         the fair value of the assets of the Parent Borrower and its
         Subsidiaries on a consolidated basis, at a fair valuation, will exceed
         the debts and liabilities, subordinated, contingent or otherwise, of
         the Parent Borrower and its Subsidiaries on a consolidated basis; (b)
         the present fair saleable value of the Property of the Parent Borrower
         and its Subsidiaries on a consolidated basis will be greater than the

         Parent Borrower and its Subsidiaries on a consolidated basis on their
         debts and other liabilities, subordinated, contingent or otherwise, as
         such debts and other liabilities become absolute and matured; (c) the
         Parent


                                      -44-

   52



         Borrower and its Subsidiaries on a consolidated basis will be able to
         pay their debts and liabilities, subordinated, contingent or otherwise,
         as such debts and liabilities become absolute and matured; and (d) the
         Parent Borrower and its Subsidiaries on a consolidated basis will not
         have unreasonably small capital with which to conduct the businesses in
         which they are engaged as such businesses are now conducted and are
         proposed to be conducted after the date hereof.

                  (ii) The Parent Borrower does not intend to, or to permit any
         of its Subsidiaries to, and does not believe that it or any of its
         Subsidiaries will, incur debts beyond its ability to pay such debts as
         they mature, taking into account the timing of and amounts of cash to
         be received by it or any such Subsidiary and the timing of the amounts
         of cash to be payable on or in respect of its Indebtedness or the
         Indebtedness of any such Subsidiary.

   54

         6.2. Use of Proceeds. The Parent Borrower will, and will cause each
Subsidiary to, use the proceeds of the Credit Extensions for general corporate
purposes, to finance a portion of the purchase price of the November 2000

Subsidiaries and the Target, and to finance Acquisitions and Investments

each jurisdiction in which its business is conducted except where failure to
maintain such authority could not individually or in the aggregate reasonably be
expected to have a Material Adverse Effect.

appropriate proceedings and with respect to which adequate reserves have been
set aside in accordance with Agreement Accounting Principles or (ii) where

Material Adverse Effect.

cause each Subsidiary to, do all things necessary to maintain, preserve, protect
and keep its Property in good repair, working order and condition, and make all
necessary and proper repairs, renewals and replacements so that its business
carried on in connection therewith may be properly conducted at all times except
where such failure could not individually or in the aggregate reasonably be
expected to have a Material Adverse Effect.

         6.9. Inspection. The Parent Borrower will, and will cause each
Subsidiary to, permit the Administrative Agent and the Lenders, by their
respective representatives and agents, to inspect any of the Property, books and
financial records of the Parent Borrower and each Subsidiary, to examine and
make copies of the books of accounts and other financial records of the Parent
Borrower and each Subsidiary, and to discuss the affairs, finances and accounts

same by, their respective officers at such reasonable times and intervals as the
Administrative Agent or any Lender may designate.

Subsidiary to, declare or pay any dividends or make any distributions on its
capital stock (other than dividends payable in its own capital stock) or redeem,
repurchase or otherwise acquire or retire any of its capital stock at any time
outstanding, except that (i) any Subsidiary may declare and pay dividends or
make distributions to the Parent Borrower or to a Wholly-Owned Subsidiary and

                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

         8.1. Acceleration; Facility LC Collateral Account.

                  (i) If any Default described in Section 7.6 or 7.7 occurs, the
         obligations of the Lenders to make Loans hereunder and the obligation
         and power of the LC Issuer to issue Facility LCs shall automatically
         terminate and the Obligations shall immediately become due and payable
         without any election or action on the part of the Administrative Agent,
         the LC Issuer or any Lender and the Parent Borrower will be and become
         thereby unconditionally obligated, without any further notice, act or
         demand, to pay to the Administrative Agent an amount in immediately
         available funds, which funds shall be held in the Facility LC
         Collateral Account, equal to the difference of (x) the amount of LC
         Obligations at such time, less (y) the amount on deposit in the
         Facility LC Collateral Account at such time which is free and clear of
         all rights and claims of third


                                      -56-

   64



         parties and has not been applied against the Obligations (such
         difference, the "Collateral Shortfall Amount"). If any other Default
         occurs, the Required Lenders (or the Administrative Agent with the
         consent of the Required Lenders) may (a) terminate or suspend the
         obligations of the Lenders to make Loans hereunder and the obligation
         and power of the LC Issuer to issue Facility LCs, or declare the
         Obligations to be due and payable, or both, whereupon the Obligations
         shall become immediately due and payable, without presentment, demand,
         protest or notice of any kind, all of which the Parent Borrower hereby
         expressly waives, and (b) upon notice to the Parent Borrower and in
         addition to the continuing right to demand payment of all amounts
         payable under this Agreement, make demand on the Parent Borrower to
         pay, and the Parent Borrower will, forthwith upon such demand and
         without any further notice or act, pay to the Administrative Agent the
         Collateral Shortfall Amount, which funds shall be deposited in the
         Facility LC Collateral Account.

                  (ii) If at any time while any Default is continuing, the
         Administrative Agent determines that the Collateral Shortfall Amount at
         such time is greater than zero, the Administrative Agent may make
         demand on the Parent Borrower to pay, and the Parent Borrower will,
         forthwith upon such demand and without any further notice or act, pay
         to the Administrative Agent the Collateral Shortfall Amount, which
         funds shall be deposited in the Facility LC Collateral Account.

                  (iii) The Administrative Agent may at any time or from time to
         time after funds are deposited in the Facility LC Collateral Account,
         apply such funds to the payment of the Obligations and any other
         amounts as shall from time to time have become due and payable by the
         Parent Borrower to the Lenders or the LC Issuer under the Loan
         Documents.

                  (iv) At any time while any Default is continuing, neither the
         Parent Borrower nor any Person claiming on behalf of or through the
         Parent Borrower shall have any right to withdraw any of the funds held
         in the Facility LC Collateral Account. After all of the Obligations
         have been indefeasibly paid in full and the Aggregate Commitment has
         been terminated, any funds remaining in the Facility LC Collateral
         Account shall be returned by the Administrative Agent to the Parent
         Borrower or paid to whomever may be legally entitled thereto at such
         time.

                  (v) If, within 30 days after acceleration of the maturity of
         the Obligations or termination of the obligations of the Lenders to
         make Loans and the obligation and power of the LC Issuer to issue
         Facility LCs hereunder as a result of any Default (other than any
         Default as described in Section 7.6 or 7.7) and before any judgment or
         decree for the payment of the Obligations due shall have been obtained
         or entered, the Required Lenders (in their sole discretion) shall so
         direct, the Administrative Agent shall, by notice to the Borrowers,
         rescind and annul such acceleration and/or termination.

         8.2. Amendments. Subject to the provisions of this Article VIII, the
Required Lenders (or the Administrative Agent with the consent in writing of the
Required Lenders) and the Borrowers may enter into agreements supplemental
hereto for the purpose of adding or modifying any provisions to the Loan
Documents or changing in any manner the rights of the Lenders or the Borrowers
hereunder or waiving


                                      -57-

   65



any Default hereunder; provided, however, that no such supplemental agreement
shall, without the consent of all of the Lenders:

                  (i) Extend the final maturity of any Loan, or extend the
         expiry date of any Facility LC to a date after the Facility Termination
         Date or postpone any regularly scheduled payment of principal of any
         Loan or forgive all or any portion of the principal amount thereof or
         any Reimbursement Obligation related thereto, or reduce the rate or the
         unused fee due under Section 2.5 or extend the time of payment of
         interest or fees thereon or Reimbursement Obligations related thereto.

                  (ii) Reduce the percentage specified in the definition of
         Required Lenders.

                  (iii) Extend the Facility Termination Date, or reduce the
         amount or extend the payment date for, the mandatory payments required
         under Section 2.2, or increase the amount of the Aggregate Commitment,
         the Commitment of any Lender hereunder or the commitment to issue
         Facility LCs, or permit either Borrower to assign its rights under this
         Agreement.

                  (iv) Amend this Section 8.2.

                  (v) Release any Guarantor except where the sale of all or
         substantially all of the assets or equity interests in a Guarantor is
         otherwise permitted hereunder, in which event the Administrative Agent
         shall execute and deliver to Parent Borrower such release upon such
         sale.

No amendment of any provision of this Agreement relating to the Administrative
Agent shall be effective without the written consent of the Administrative
Agent, and no amendment of any provision relating to the LC Issuer shall be
effective without the written consent of the LC Issuer. The Administrative Agent
may waive payment of the fee required under Section 12.3.2 without obtaining the
consent of any other party to this Agreement.

         8.3. Preservation of Rights. No delay or omission of the Lenders, the
LC Issuer or the Administrative Agent to exercise any right under the Loan
Documents shall impair such right or be construed to be a waiver of any Default
or an acquiescence therein, and the making of a Credit Extension notwithstanding
the existence of a Default or the inability of the Borrowers to satisfy the
conditions precedent to such Credit Extension shall not constitute any waiver or
acquiescence. Any single or partial exercise of any such right shall not
preclude other or further exercise thereof or the exercise of any other right,
and no waiver, amendment or other variation of the terms, conditions or
provisions of the Loan Documents whatsoever shall be valid unless in writing
signed by the Lenders required pursuant to Section 8.2, and then only to the
extent in such writing specifically set forth. All remedies contained in the
Loan Documents or by law afforded shall be cumulative and all shall be available
to the Administrative Agent, the LC Issuer and the Lenders until the Obligations
have been paid in full.

                               GENERAL PROVISIONS

         9.1. Survival of Representations. All representations and warranties of
the Borrowers contained in this Agreement shall survive the making of the Credit
Extensions herein contemplated.

         9.2. Governmental Regulation. Anything contained in this Agreement to
the contrary notwithstanding, neither the LC Issuer nor any Lender shall be
obligated to extend credit to either Borrower in violation of any limitation or
prohibition provided by any applicable statute or regulation.

         9.3. Headings. Section headings in the Loan Documents are for
convenience of reference only, and shall not govern the interpretation of any of
the provisions of the Loan Documents.

         9.4. ENTIRE AGREEMENT. THE LOAN DOCUMENTS EMBODY THE ENTIRE AGREEMENT
AND UNDERSTANDING AMONG THE BORROWERS, THE ADMINISTRATIVE AGENT, THE LC ISSUER
AND THE LENDERS AND SUPERSEDE ALL PRIOR AGREEMENTS AND UNDERSTANDINGS AMONG THE
BORROWERS, THE ADMINISTRATIVE AGENT, THE LC ISSUER AND THE LENDERS RELATING TO
THE SUBJECT MATTER THEREOF OTHER THAN THE FEE LETTER DESCRIBED IN SECTION 10.13.
THE LOAN DOCUMENTS MAY NOT BE CONTRADICTED OR VARIED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS OF THE PARTIES
HERETO. THERE ARE NO ORAL AGREEMENTS AMONG THE PARTIES HERETO.

         9.5. Several Obligations; Benefits of this Agreement. The respective
obligations of the Lenders hereunder are several and not joint and no Lender
shall be the partner or agent of any other (except to the extent to which the
Administrative Agent is authorized to act as such). The failure of any Lender to
perform any of its obligations hereunder shall not relieve any other Lender from
any of its obligations hereunder. This Agreement shall not be construed so as to
confer any right or benefit upon any Person other than the parties to this
Agreement and their respective successors and assigns, provided, however, that
the parties hereto expressly agree that the Arranger shall enjoy the benefits of
the provisions of Sections 9.6, 9.10 and 10.11 to the extent specifically set
forth therein and shall have the right to enforce such provisions on its own
behalf and in its own name to the same extent as if it were a party to this
Agreement.

         9.6. Expenses; Indemnification.

                  (i) The Borrowers shall reimburse the Administrative Agent and
         the Arranger for any costs, internal charges for fees and time charges
         of attorneys who are employees of the Administrative Agent, the
         Arranger, the LC Issuer and out-of-pocket expenses (including
         attorneys' fees and time charges of attorneys for the Administrative
         Agent) paid or incurred by the Administrative Agent or the Arranger in
         connection with the preparation, negotiation, execution, delivery,
         syndication, review, amendment, modification, and administration of the
         Loan


                                      -59-

   67



         Documents. The Borrowers also agree to reimburse the Administrative
         Agent, the Arranger, the LC Issuer and the Lenders for any costs,
         internal charges for fees and time charges of attorneys who are
         employees of the Administrative Agent, the Arranger, the LC Issuer, the
         Lenders and out-of-pocket expenses (including attorneys' fees and time
         charges of attorneys for the Administrative Agent, the Arranger, the LC
         Issuer and the Lenders) paid or incurred by the Administrative Agent,
         the Arranger, the LC Issuer or any Lender in connection with the
         collection and enforcement of the Loan Documents. Expenses being
         reimbursed by the Borrowers under this Section include, without
         limitation, costs and expenses incurred in connection with the Reports
         described in the following sentence. The Borrowers acknowledge that
         from time to time Bank One may prepare and may distribute to the
         Lenders (but shall have no obligation or duty to prepare or to
         distribute to the Lenders) certain audit reports (the "Reports")
         pertaining to the Borrowers' assets for internal use by Bank One from
         information furnished to it by or on behalf of the Borrowers, after
         Bank One has exercised its rights of inspection pursuant to this
         Agreement.

                  (ii) THE BORROWERS HEREBY FURTHER AGREE TO INDEMNIFY THE
         ADMINISTRATIVE AGENT, THE ARRANGER, THE LC ISSUER AND EACH LENDER, ITS
         DIRECTORS, OFFICERS AND EMPLOYEES AGAINST ALL LOSSES, CLAIMS, DAMAGES,
         PENALTIES, JUDGMENTS, LIABILITIES AND EXPENSES (INCLUDING, WITHOUT
         LIMITATION, ALL EXPENSES OF LITIGATION OR PREPARATION THEREFOR WHETHER
         OR NOT THE ADMINISTRATIVE AGENT, THE ARRANGER, THE LC ISSUER OR ANY
         LENDER IS A PARTY THERETO) WHICH ANY OF THEM MAY PAY OR INCUR ARISING
         OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, THE
         TRANSACTIONS CONTEMPLATED HEREBY OR THE DIRECT OR INDIRECT APPLICATION
         OR PROPOSED APPLICATION OF THE PROCEEDS OF ANY CREDIT EXTENSION
         HEREUNDER EXCEPT TO THE EXTENT THAT THEY ARE DETERMINED IN A FINAL
         NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE
         RESULTED FROM THE GROSS NEGLIGENCE, BAD FAITH OR WILLFUL MISCONDUCT OF
         THE PARTY SEEKING INDEMNIFICATION; PROVIDED HOWEVER, THAT IN NO EVENT
         SHALL THE BORROWERS BE LIABLE UNDER THIS SECTION 9.6 FOR ANY LOST
         PROFITS OR FOR ANY SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE
         DAMAGES. THE OBLIGATIONS OF THE BORROWERS UNDER THIS SECTION 9.6 SHALL
         SURVIVE THE TERMINATION OF THIS AGREEMENT.

         9.7. Numbers of Documents. All statements, notices, closing documents,
and requests hereunder shall be furnished to the Administrative Agent with
sufficient counterparts so that the Administrative Agent may furnish one to each
of the Lenders.

accounting terms used herein shall be interpreted and all accounting
determinations hereunder shall be made in accordance with Agreement Accounting
Principles.

         9.9. Severability of Provisions. Any provision in any Loan Document
that is held to be inoperative, unenforceable, or invalid in any jurisdiction
shall, as to that jurisdiction, be inoperative, unenforceable, or invalid
without affecting the remaining provisions in that jurisdiction or the
operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared
to be severable.

         9.10. Nonliability of Lenders. The relationship between the Borrowers
on the one hand and the Lenders, the LC Issuer and the Administrative Agent on
the other hand shall be solely that of borrower and lender. Neither the
Administrative Agent, the Arranger, the LC Issuer nor any Lender shall have any
fiduciary responsibilities to the Borrowers. Neither the Administrative Agent,
the Arranger, the LC Issuer nor any Lender undertakes any responsibility to the
Borrowers to review or inform the Borrowers of any matter in connection with any
phase of the Borrowers' business or operations. Each Borrower agrees that
neither the Administrative Agent, the Arranger, the LC Issuer nor any Lender
shall have liability to the Borrowers (whether sounding in tort, contract or
otherwise) for losses suffered by the Borrowers in connection with, arising out
of, or in any way related to, the transactions contemplated and the relationship
established by the Loan Documents, or any act, omission or event occurring in
connection therewith, unless it is determined in a final non-appealable judgment
by a court of competent jurisdiction that such losses resulted from the gross
negligence, bad faith or willful misconduct of the party from which recovery is
sought. Neither the Administrative Agent, the Arranger, the LC Issuer nor any
Lender shall have any liability with respect to, and each Borrower hereby
waives, releases and agrees not to sue for, any special, indirect or
consequential damages suffered by the Borrowers in connection with, arising out
of, or in any way related to the Loan Documents or the transactions contemplated
thereby.

         9.11. Confidentiality. Each Lender agrees to hold any confidential
information which it may receive from the Borrowers pursuant to this Agreement
in confidence, except for disclosure (i) to its Affiliates and to other Lenders
and their respective Affiliates, (ii) to legal counsel, accountants, and other
professional advisors to such Lender or to a Transferee, (iii) to regulatory
officials, (iv) to any Person as requested pursuant to or as required by law,
regulation, or legal process, (v) to any Person in connection with any legal
proceeding to which such Lender is a party, (vi) to such Lender's direct or
indirect contractual counterparties in swap agreements or to legal counsel,
accountants and other professional advisors to such counterparties, and (vii)
permitted by Section 12.4.

         9.12. Nonreliance. Each Lender hereby represents that it is not relying
on or looking to any margin stock (as defined in Regulation U of the Board of
Governors of the Federal Reserve System) for the repayment of the Credit
Extensions provided for herein.

         9.13. Disclosure. Each Borrower and each Lender hereby acknowledge and
agree that Bank One and/or its Affiliates from time to time may hold investments
in, make other loans to, or have other relationships with the Parent Borrower
and its Affiliates.

         9.14. Maximum Interest Rate. No provision of this Agreement or of any
other Loan Document shall require the payment or the collection of interest in
excess of the maximum amount permitted by applicable law. If any excess of
interest in such respect is hereby provided for, or shall be adjudicated to


                                      -61-

   69



be so provided, in any Loan Document or otherwise in connection with this loan
transaction, the provisions of this Section shall govern and prevail and neither
Borrower nor the sureties, guarantors, successors, or assigns of either Borrower
shall be obligated to pay the excess amount of such interest or any other excess
sum paid for the use, forbearance, or detention of sums loaned pursuant hereto.
In the event any Lender or the Administrative Agent ever receives, collects, or
applies as interest any such sum, such amount which would be in excess of the
maximum amount permitted by applicable law shall be applied as a payment and
reduction of the principal of the indebtedness owing under this Agreement; and,
if the principal owing has been paid in full, any remaining excess shall
forthwith be paid to the Borrowers. In determining whether or not the interest
paid or payable exceeds the Maximum Rate, the Borrowers, the Administrative
Agent, and each Lender shall, to the extent permitted by applicable law, (a)
characterize any non-principal payment as an expense, fee, or premium rather
than as interest, (b) exclude voluntary prepayments and the effects thereof, and
(c) amortize, prorate, allocate, and spread in equal or unequal parts the total
amount of interest throughout the entire contemplated term of the indebtedness
owing pursuant to this Agreement so that interest for the entire term does not
exceed the Maximum Rate.

         9.15. Non-Application of Chapter 346 of Texas Finance Code. The
provisions of Chapter 346 of the Texas Credit Code, as amended from time to
time, are specifically declared by the parties hereto not to be applicable to
this Agreement or any of the other Loan Documents or to the transactions
contemplated hereby.

         9.16. Survival of Prior Agreements. The rights and privileges
(excluding the confidentiality and indemnification provisions which are being
restated pursuant to this Agreement) afforded the Administrative Agent and the
Arranger in that certain commitment letter and that certain fee letter, each
dated August 9, 2000 among such Persons and Parent Borrower, shall survive the
execution and delivery of this Agreement, and the Administrative Agent and the
Arranger shall continue to be entitled to the benefits thereof.


                                    ARTICLE X

                            THE ADMINISTRATIVE AGENT

         10.1. Appointment; Nature of Relationship. Bank One, Texas, NA is
hereby appointed by each of the Lenders as its contractual representative
(herein referred to as the "Administrative Agent") hereunder and under each
other Loan Document, and each of the Lenders irrevocably authorizes the
Administrative Agent to act as the contractual representative of such Lender
with the rights and duties expressly set forth herein and in the other Loan
Documents. The Administrative Agent agrees to act as such contractual
representative upon the express conditions contained in this Article X.
Notwithstanding the use of the defined term "Administrative Agent," it is
expressly understood and agreed that the Administrative Agent shall not have any
fiduciary responsibilities to any Lender by reason of this Agreement or any
other Loan Document and that the Administrative Agent is merely acting as the
contractual representative of the Lenders with only those duties as are
expressly set forth in this Agreement and the other Loan Documents. In its
capacity as the Lenders' contractual representative, the


                                      -62-

   70



Administrative Agent (i) does not hereby assume any fiduciary duties to any of
the Lenders, (ii) is a "representative" of the Lenders within the meaning of
Section 9-105 of the Uniform Commercial Code and (iii) is acting as an
independent contractor, the rights and duties of which are limited to those
expressly set forth in this Agreement and the other Loan Documents. Each of the
Lenders hereby agrees to assert no claim against the Administrative Agent on any
agency theory or any other theory of liability for breach of fiduciary duty, all
of which claims each Lender hereby waives.

         10.2. Powers. The Administrative Agent shall have and may exercise such
powers under the Loan Documents as are specifically delegated to the
Administrative Agent by the terms of each thereof, together with such powers as
are reasonably incidental thereto. The Administrative Agent shall have no
implied duties to the Lenders, or any obligation to the Lenders to take any
action thereunder except any action specifically provided by the Loan Documents
to be taken by the Administrative Agent.

         10.3. General Immunity. Neither the Administrative Agent nor any of its
directors, officers, agents or employees shall be liable to the Borrowers, the
Lenders or any Lender for any action taken or omitted to be taken by it or them
hereunder or under any other Loan Document or in connection herewith or
therewith except to the extent such action or inaction is determined in a final
non-appealable judgment by a court of competent jurisdiction to have arisen from
the gross negligence, bad faith or willful misconduct of such Person.

         10.4. No Responsibility for Credit Extensions, Recitals, etc. Neither
the Administrative Agent nor any of its directors, officers, agents or employees
shall be responsible for or have any duty to ascertain, inquire into, or verify
(a) any statement, warranty or representation made in connection with any Loan
Document or any borrowing hereunder; (b) the performance or observance of any of
the covenants or agreements of any obligor under any Loan Document, including,
without limitation, any agreement by an obligor to furnish information directly
to each Lender; (c) the satisfaction of any condition specified in Article IV,
except receipt of items required to be delivered solely to the Administrative
Agent; (d) the existence or possible existence of any Default or Unmatured
Default; (e) the validity, enforceability, effectiveness, sufficiency or
genuineness of any Loan Document or any other instrument or writing furnished in
connection therewith; (f) the value, sufficiency, creation, perfection or
priority of any Lien in any collateral security; or (g) the financial condition
of the Borrowers or any guarantor of any of the Obligations or of any of the
Parent Borrower's or any such guarantor's respective Subsidiaries. The
Administrative Agent shall have no duty to disclose to the Lenders information
that is not required to be furnished by the Borrowers to the Administrative
Agent at such time, but is voluntarily furnished by the Borrowers to the
Administrative Agent (either in its capacity as Administrative Agent or in its
individual capacity).

         10.5. Action on Instructions of Lenders. The Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting,
hereunder and under any other Loan Document in accordance with written
instructions signed by the Required Lenders, and such instructions and any
action taken or failure to act pursuant thereto shall be binding on all of the
Lenders. The Lenders hereby acknowledge that the Administrative Agent shall be
under no duty to take any discretionary action permitted to be taken by it
pursuant to the provisions of this Agreement or any other Loan Document


                                      -63-

   71



unless it shall be requested in writing to do so by the Required Lenders. The
Administrative Agent shall be fully justified in failing or refusing to take any
action hereunder and under any other Loan Document unless it shall first be
indemnified to its satisfaction by the Lenders pro rata against any and all
liability, cost and expense that it may incur by reason of taking or continuing
to take any such action.

         10.6. Employment of Administrative Agents and Counsel. The
Administrative Agent may execute any of its duties as Administrative Agent
hereunder and under any other Loan Document by or through employees, agents, and
attorneys-in-fact and shall not be answerable to the Lenders, except as to money
or securities received by it or its authorized agents, for the default or
misconduct of any such agents or attorneys-in-fact selected by it with
reasonable care. The Administrative Agent shall be entitled to advice of counsel
concerning the contractual arrangement between the Administrative Agent and the
Lenders and all matters pertaining to the Administrative Agent's duties
hereunder and under any other Loan Document.

         10.7. Reliance on Documents; Counsel. The Administrative Agent shall be
entitled to rely upon any Note, notice, consent, certificate, affidavit, letter,
telegram, statement, paper or document believed by it to be genuine and correct
and to have been signed or sent by the proper person or persons, and, in respect
to legal matters, upon the opinion of counsel selected by the Administrative
Agent, which counsel may be employees of the Administrative Agent.

         10.8. Administrative Agent's Reimbursement and Indemnification. The
Lenders agree to reimburse and indemnify the Administrative Agent ratably in
proportion to their respective Commitments (or, if the Commitments have been
terminated, in proportion to their Commitments immediately prior to such
termination) (i) for any amounts not reimbursed by the Borrowers for which the
Administrative Agent is entitled to reimbursement by the Borrowers or either of
them under the Loan Documents, (ii) for any other expenses incurred by the
Administrative Agent on behalf of the Lenders, in connection with the
preparation, execution, delivery, administration and enforcement of the Loan
Documents (including, without limitation, for any expenses incurred by the
Administrative Agent in connection with any dispute between the Administrative
Agent and any Lender or between two or more of the Lenders) and (iii) for any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind and nature whatsoever which may be
imposed on, incurred by or asserted against the Administrative Agent in any way
relating to or arising out of the Loan Documents or any other document delivered
in connection therewith or the transactions contemplated thereby (including,
without limitation, for any such amounts incurred by or asserted against the
Administrative Agent in connection with any dispute between the Administrative
Agent and any Lender or between two or more of the Lenders), or the enforcement
of any of the terms of the Loan Documents or of any such other documents,
provided that (i) no Lender shall be liable for any of the foregoing to the
extent any of the foregoing is found in a final non-appealable judgment by a
court of competent jurisdiction to have resulted from the gross negligence or
willful misconduct of the Administrative Agent and (ii) any indemnification
required pursuant to Section 3.5(vii) shall, notwithstanding the provisions of
this Section 10.8, be paid by the relevant Lender in accordance with the
provisions thereof. The obligations of the Lenders under this Section 10.8 shall
survive payment of the Obligations and termination of this Agreement.


                                      -64-

   72



         10.9. Notice of Default. The Administrative Agent shall not be deemed
to have knowledge or notice of the occurrence of any Default or Unmatured
Default hereunder unless the Administrative Agent has received written notice
from a Lender or the Borrowers referring to this Agreement describing such
Default or Unmatured Default and stating that such notice is a "notice of
default". In the event that the Administrative Agent receives such a notice, the
Administrative Agent shall give prompt notice thereof to the Lenders.

         10.10. Rights as a Lender. In the event the Administrative Agent is a
Lender, the Administrative Agent shall have the same rights and powers hereunder
and under any other Loan Document with respect to its Commitment and its Credit
Extensions as any Lender and may exercise the same as though it were not the
Administrative Agent, and the term "Lender" or "Lenders" shall, at any time when
the Administrative Agent is a Lender, unless the context otherwise indicates,
include the Administrative Agent in its individual capacity. The Administrative
Agent and its Affiliates may accept deposits from, lend money to, and generally
engage in any kind of trust, debt, equity or other transaction, in addition to
those contemplated by this Agreement or any other Loan Document, with the Parent
Borrower or any of its Subsidiaries in which the Parent Borrower or such
Subsidiary is not restricted hereby from engaging with any other Person.

         10.11. Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Administrative Agent, the Arranger
or any other Lender and based on the financial statements prepared by the
Borrowers and such other documents and information as it has deemed appropriate,
made its own credit analysis and decision to enter into this Agreement and the
other Loan Documents. Each Lender also acknowledges that it will, independently
and without reliance upon the Administrative Agent, the Arranger or any other
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.

         10.12. Successor Administrative Agent. The Administrative Agent may
resign at any time by giving written notice thereof to the Lenders and the
Borrowers, such resignation to be effective upon the appointment of a successor
Administrative Agent or, if no successor Administrative Agent has been
appointed, forty-five days after the retiring Administrative Agent gives notice
of its intention to resign. The Administrative Agent may be removed at any time
with or without cause by written notice received by the Administrative Agent
from the Required Lenders, such removal to be effective on the date specified by
the Required Lenders. Upon any such resignation or removal, the Required Lenders
shall have the right to appoint, on behalf of the Borrowers and the Lenders, a
successor Administrative Agent. If no successor Administrative Agent shall have
been so appointed by the Required Lenders within thirty days after the resigning
Administrative Agent's giving notice of its intention to resign, then the
resigning Administrative Agent may appoint, on behalf of the Borrowers and the
Lenders, a successor Administrative Agent. Notwithstanding the previous
sentence, the Administrative Agent may at any time without the consent of either
Borrower or any Lender, appoint any of its Affiliates which is a commercial bank
as a successor Administrative Agent hereunder. If the Administrative Agent has
resigned or been removed and no successor Administrative Agent has been
appointed, the Lenders may perform all the duties of the Administrative Agent
hereunder and the Borrowers shall make all payments in respect of the
Obligations


                                      -65-

   73



to the applicable Lender and for all other purposes shall deal directly with the
Lenders. No successor Administrative Agent shall be deemed to be appointed
hereunder until such successor Administrative Agent has accepted the
appointment. Any such successor Administrative Agent shall be a commercial bank
having capital and retained earnings of at least $1,000,000,000. Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the resigning or removed Administrative Agent. Upon the effectiveness of the
resignation or removal of the Administrative Agent, the resigning or removed
Administrative Agent shall be discharged from its duties and obligations
hereunder and under the Loan Documents. After the effectiveness of the
resignation or removal of an Administrative Agent, the provisions of this
Article X shall continue in effect for the benefit of such Administrative Agent
in respect of any actions taken or omitted to be taken by it while it was acting
as the Administrative Agent hereunder and under the other Loan Documents. In the
event that there is a successor to the Administrative Agent by merger, or the
Administrative Agent assigns its duties and obligations to an Affiliate pursuant
to this Section 10.12, then the term "Prime Rate" as used in this Agreement
shall mean the prime rate, base rate or other analogous rate of the new
Administrative Agent.

         10.13. Administrative Agent and Arranger Fees. The Parent Borrower
agrees to pay to the Administrative Agent and the Arranger, for their respective
accounts, the fees agreed to by the Parent Borrower, the Administrative Agent
and the Arranger pursuant to that certain letter agreement dated August 9, 2000,
or as otherwise agreed from time to time.

         10.14. Delegation to Affiliates. The Borrowers and the Lenders agree
that the Administrative Agent may delegate any of its duties under this
Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate's
directors, officers, agents and employees) which performs duties in connection
with this Agreement shall be entitled to the same benefits of the
indemnification, waiver and other protective provisions to which the
Administrative Agent is entitled under Articles IX and X.

         10.15. Co-Agents, Documentation Agent, Syndication Agent, etc. Neither
any of the Lenders identified in this Agreement as a "co-agent" nor the
Documentation Agent or the Syndication Agent shall have any right, power,
obligation, liability, responsibility or duty under this Agreement other than
those applicable to all Lenders as such. Without limiting the foregoing, none of
such Lenders shall have or be deemed to have a fiduciary relationship with any
Lender. Each Lender hereby makes the same acknowledgments with respect to such
Lenders as it makes with respect to the Administrative Agent in Section 10.11.


                                      -66-

   74



                                   ARTICLE XI

                            SETOFF; RATABLE PAYMENTS

         11.1. Setoff. In addition to, and without limitation of, any rights of
the Lenders under applicable law, if either Borrower becomes insolvent, however
evidenced, or any Default occurs, any and all deposits (including all account
balances, whether provisional or final and whether or not collected or
available) and any other Indebtedness at any time held or owing by any Lender or
any Affiliate of any Lender to or for the credit or account of either Borrower
may be offset and applied toward the payment of the Obligations owing to such
Lender, whether or not the Obligations, or any part thereof, shall then be due.

         11.2. Ratable Payments. If any Lender, whether by setoff or otherwise,
has payment made to it upon its Outstanding Credit Exposure (other than payments
received pursuant to Section 3.1, 3.2, 3.4 or 3.5) in a greater proportion than
that received by any other Lender, such Lender agrees, promptly upon demand, to
purchase a portion of the Aggregate Outstanding Credit Exposure held by the
other Lenders so that after such purchase each Lender will hold its Pro Rata
Share of the Aggregate Outstanding Credit Exposure. If any Lender, whether in
connection with setoff or amounts which might be subject to setoff or otherwise,
receives collateral or other protection for its Obligations or such amounts
which may be subject to setoff, such Lender agrees, promptly upon demand, to
take such action necessary such that all Lenders share in the benefits of such
collateral ratably in proportion to their respective Pro Rata Share of the
Aggregate Outstanding Credit Exposure. In case any such payment is disturbed by
legal process, or otherwise, appropriate further adjustments shall be made.

                BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

         12.1. Successors and Assigns. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrowers and
the Lenders and their respective successors and assigns, except that (i) neither
Borrower shall have the right to assign its rights or obligations under the Loan
Documents and (ii) any assignment by any Lender must be made in compliance with
Section 12.3. The parties to this Agreement acknowledge that clause (ii) of this
Section 12.1 relates only to absolute assignments and does not prohibit
assignments creating security interests, including, without limitation, any
pledge or assignment by any Lender of all or any portion of its rights under
this Agreement and any Note to a Federal Reserve Bank; provided, however, that
no such pledge or assignment creating a security interest shall release the
transferor Lender from its obligations hereunder unless and until the parties
thereto have complied with the provisions of Section 12.3. The Administrative
Agent may treat the Person which made any Credit Extension or which holds any
Note as the owner thereof for all purposes hereof unless and until such Person
complies with Section 12.3; provided, however, that the Administrative Agent may
in its discretion (but shall not be required to) follow instructions from the
Person which made any Credit Extension or which holds any Note to direct
payments relating to such Credit Extension or Note to another Person. Any
assignee of the rights to any Credit Extension or any Note agrees by acceptance
of such


                                      -67-

   75



assignment to be bound by all the terms and provisions of the Loan Documents.
Any request, authority or consent of any Person, who at the time of making such
request or giving such authority or consent is the owner of the rights to any
Credit Extension (whether or not a Note has been issued in evidence thereof),
shall be conclusive and binding on any subsequent holder or assignee of the
rights to such Credit Extension.

         12.2. Participations.

                  12.2.1. Permitted Participants; Effect. Any Lender may, in the
         ordinary course of its business and in accordance with applicable law,
         at any time sell to one or more banks or other entities
         ("Participants") participating interests in any Outstanding Credit
         Exposure of such Lender, any Note held by such Lender, any Commitment
         of such Lender or any other interest of such Lender under the Loan
         Documents. In the event of any such sale by a Lender of participating
         interests to a Participant, such Lender's obligations under the Loan
         Documents shall remain unchanged, such Lender shall remain solely
         responsible to the other parties hereto for the performance of such
         obligations, such Lender shall remain the owner of its Outstanding
         Credit Exposure and the holder of any Note issued to it in evidence
         thereof for all purposes under the Loan Documents, all amounts payable
         by the Borrowers under this Agreement shall be determined as if such
         Lender had not sold such participating interests, and the Borrowers and
         the Administrative Agent shall continue to deal solely and directly
         with such Lender in connection with such Lender's rights and
         obligations under the Loan Documents.

                  12.2.2. Voting Rights. Each Lender shall retain the sole right
         to approve, without the consent of any Participant, any amendment,
         modification or waiver of any provision of the Loan Documents other
         than any amendment, modification or waiver with respect to any Credit
         Extension or Commitment in which such Participant has an interest which
         forgives principal, interest, fees or any Reimbursement Obligation or
         reduces the interest rate or fees payable with respect to any such
         Credit Extension or Commitment, extends the Facility Termination Date,
         postpones any date fixed for any regularly-scheduled payment of
         principal of or interest on any Credit Extension in which such
         Participant has an interest, or any regularly-scheduled payment of fees
         on any such Credit Extension or Commitment, releases any guarantor of
         any such Credit Extension (except as otherwise permitted by Section
         8.2(v)) or releases any collateral held in the Facility LC Collateral
         Account (except in accordance with the terms hereof) or all or
         substantially all of any other collateral, if any, securing any such
         Credit Extension.

                  12.2.3. Benefit of Setoff. Each Borrower agrees that each
         Participant shall be deemed to have the right of setoff provided in
         Section 11.1 in respect of its participating interest in amounts owing
         under the Loan Documents to the same extent as if the amount of its
         participating interest were owing directly to it as a Lender under the
         Loan Documents, provided that each Lender shall retain the right of
         setoff provided in Section 11.1 with respect to the amount of
         participating interests sold to each Participant. The Lenders agree to
         share with each Participant, and each Participant, by exercising the
         right of setoff provided in Section 11.1, agrees to share with each


                                      -68-

   76



         Lender, any amount received pursuant to the exercise of its right of
         setoff, such amounts to be shared in accordance with Section 11.2 as if
         each Participant were a Lender.

         12.3. Assignments.

                  12.3.1. Permitted Assignments. Any Lender may, in the ordinary
         course of its business and in accordance with applicable law, at any
         time assign to one or more banks or other entities ("Purchasers") all
         or any part of its rights and obligations under the Loan Documents;
         provided however, if such assignments are of Eurodollar Loans prior to
         the last day of the Interest Period applicable thereto, the Borrowers
         will not be required to pay the breakage fees, if any, associated with
         such assignment. Such assignment shall be substantially in the form of
         Exhibit C or in such other form as may be agreed to by the parties
         thereto. The consent of the Borrowers, the Administrative Agent and the
         LC Issuer shall be required prior to an assignment becoming effective
         with respect to a Purchaser which is not a Lender or an Affiliate
         thereof; provided, however, that if a Default has occurred and is
         continuing, the consent of the Borrowers shall not be required. Such
         consent shall not be unreasonably withheld or delayed. Each such
         assignment with respect to a Purchaser which is not a Lender or an
         Affiliate thereof shall (unless each of the Parent Borrower and the
         Administrative Agent otherwise consents) be in an amount not less than
         the lesser of (i) $5,000,000 or (ii) the remaining amount of the
         assigning Lender's Commitment (calculated as at the date of such
         assignment) or outstanding Credit Extensions (if the applicable
         Commitment has been terminated).

                  12.3.2. Effect; Effective Date. Upon (i) delivery to the
         Administrative Agent of a notice of assignment, substantially in the
         form attached as Exhibit I to Exhibit C (a "Notice of Assignment"),
         together with any consents required by Section 12.3.1, and (ii)
         effective on and after January 9, 2001, payment of a $4,000 fee to the
         Administrative Agent for processing such assignment, such assignment
         shall become effective on the effective date specified in such Notice
         of Assignment. The Notice of Assignment shall contain a representation
         by the Purchaser to the Administrative Agent and the Borrowers to the
         effect that none of the consideration used to make the purchase of the
         Commitment and Outstanding Credit Exposure under the applicable
         assignment agreement are "plan assets" as defined under ERISA and that
         the rights and interests of the Purchaser in and under the Loan
         Documents will not be "plan assets" under ERISA. On and after the
         effective date of such assignment, such Purchaser shall for all
         purposes be a Lender party to this Agreement and any other Loan
         Document executed by or on behalf of the Lenders and shall have all the
         rights and obligations of a Lender under the Loan Documents, to the
         same extent as if it were an original party hereto, and no further
         consent or action by the Borrowers, the Lenders or the Administrative
         Agent shall be required to release the transferor Lender with respect
         to the percentage of the Aggregate Commitment and Outstanding Credit
         Exposure assigned to such Purchaser. Upon the consummation of any
         assignment to a Purchaser pursuant to this Section 12.3.2, the
         transferor Lender, the Administrative Agent and the Borrowers shall, if
         the transferor Lender or the Purchaser desires that its Loans be
         evidenced by Notes, make appropriate arrangements so that new Notes or,
         as appropriate, replacement Notes are issued to such transferor Lender
         and new Notes or, as appropriate, replacement Notes, are issued to such


                                      -69-

   77



         Purchaser, in each case in principal amounts reflecting their
         respective Commitments, as adjusted pursuant to such assignment.

         12.4. Dissemination of Information. Each Borrower authorizes each
Lender to disclose to any Participant or Purchaser or any other Person acquiring
an interest in the Loan Documents by operation of law (each a "Transferee") and
any prospective Transferee any and all information in such Lender's possession
concerning the creditworthiness of the Parent Borrower and its Subsidiaries,
including without limitation any information contained in any Reports; provided
that each Transferee and prospective Transferee agrees to be bound by Section
9.11 of this Agreement.

         12.5. Tax Treatment. If any interest in any Loan Document is
transferred to any Transferee which is organized under the laws of any
jurisdiction other than the United States or any State thereof, the transferor
Lender shall cause such Transferee, concurrently with the effectiveness of such
transfer, to comply with the provisions of Section 3.5(iv).


                                  ARTICLE XIII

specified in this Section and confirmation of receipt is received, (ii) if given
by mail, 72 hours after such communication is deposited in the mails with first
class postage prepaid, addressed as aforesaid, or (iii) if given by any other
means, when delivered (or, in the case of electronic transmission, received) at

Administrative Agent under Article II shall not be effective until received.

any Lender may each change the address for service of notice upon it by a notice
in writing to the other parties hereto.

which taken together shall constitute one agreement, and any of the parties
hereto may execute this Agreement by signing any such counterpart. This
Agreement shall be effective when it has been executed by the Borrowers, the
Administrative Agent, the LC Issuer and the Lenders and each party has notified
the Administrative Agent by facsimile transmission or telephone that it has
taken such action.

         For the purposes of this Schedule, the following terms have the
following meanings, subject to the final paragraph of this Schedule:

         "Financials" means the annual or quarterly financial statements of the
Parent Borrower delivered pursuant to Section 6.1(i) or (ii).

         "Level I Status" exists at any date if, as of the last day of the
fiscal quarter of the Parent Borrower referred to in the most recent Financials,
the Leverage Ratio is less than 1.00 to 1.00.

         "Level II Status" exists at any date if, as of the last day of the
fiscal quarter of the Parent Borrower referred to in the most recent Financials,
(i) the Parent Borrower has not qualified for Level I Status and (ii) the
Leverage Ratio is greater than or equal to 1.00 to 1.00 but less than 1.50 to
1.00.

         "Level III Status" exists at any date if, as of the last day of the
fiscal quarter of the Parent Borrower referred to in the most recent Financials,
(i) the Parent Borrower has not qualified for Level I Status or Level II Status
and (ii) the Leverage Ratio is greater than or equal to 1.50 to 1.00 but less
than 2.00 to 1.00.

         "Level IV Status" exists at any date if the Parent Borrower has not
qualified for Level I Status, Level II Status or Level III Status.

         "Status" means either Level I Status, Level II Status, Level III Status
or Level IV Status.

         The Applicable Margin and Applicable Fee Rate shall be determined in
accordance with the foregoing table based on the Parent Borrower's Status as
reflected in the then most recent Financials. Adjustments, if any, to the
Applicable Margin or Applicable Fee Rate shall be effective five Business Days
after the Administrative Agent has received the applicable Financials. If the
Parent Borrower fails to deliver the Financials to the Administrative Agent at
the time required pursuant to Section 6.1, then the Applicable Margin and
Applicable Fee Rate shall be the highest Applicable Margin and Applicable Fee


   92

third fiscal quarter of fiscal year 2001, and (b) the Applicable Fee Rate shall
be 0.50% if at any time during such fiscal quarter the average daily Aggregate
Outstanding Credit Exposure is less than 50% of the Aggregate Commitment.
