on account thereof, Agent will pay to such Lender its participating interest in
such amount (appropriately adjusted, in the case of interest payments, to
reflect the period of time during which such Lender's participating interest was
outstanding and funded) which payment shall be subject to repayment by such
Lender if such payment received by Agent is required to be returned. Each
Lender's obligation to purchase such participating interests shall be absolute
and unconditional and shall not be affected by any circumstance, including,
without limitation, (A) any set-off, counterclaim, recoupment, defense or other
right which such Lender or any other Person may have against Agent or any other
Person for any reason whatsoever; (B) the occurrence or continuance of a Default
or an Unmatured Default or the termination of the Commitments; (C) any adverse
change in the condition (financial or otherwise) of the Borrower or any other
Person; (D) any breach of this Agreement by the Borrower or any other Lender; or
(E) any other circumstance, happening or event whatsoever, whether or not
similar to any of the foregoing. Each Swing Loan, once so participated by any
Lender, shall cease to be a Swing Loan with respect to that amount for purposes
of this Agreement but shall continue to be a Loan.

         2.08. Optional Principal Payments. The Borrower may from time to time
pay, without penalty or premium, (i) all outstanding Floating Rate Advances, or
(ii) for any outstanding Floating Rate Advance (other than a Swing Loan), any
portion of such Floating Rate Advance in a minimum aggregate amount of
$1,000,000 or any integral multiple of $100,000 in excess thereof, in each case
upon prior notice to the Agent by 12:00 p.m. noon (Chicago time) two (2)
Business Days prior to the proposed prepayment. The Borrower may from time to
time pay, without penalty or premium, all or any portion of outstanding Swing
Loans, but partial payments thereon shall be in an aggregate principal amount of
at least $100,000, upon prior notice to the Agent by 12:00 p.m. noon (Chicago
time) on the same Business Day as the date of the proposed prepayment. The
Borrower may from time to time pay, subject to the payment of any funding
indemnification amounts required by


                                       20
   27




Section 3.04 but without penalty or premium, all outstanding Eurodollar Advances
of a Eurodollar Loan, upon three (3) Business Days' prior notice to the Agent.

         2.09. Method of Selecting Types and Interest Periods for New Advances.
The Borrower shall select the Type of Advance and, in the case of each
Eurodollar Advance, the Interest Period applicable thereto from time to time;
provided, that Borrower may not select a Eurodollar Advance as the Type of
Advance if a Default or Unmatured Default is in existence on the proposed
Borrowing Date. The Borrower shall give the Agent irrevocable notice (a
"Borrowing Notice") substantially in the form of Exhibit B not later than 12:00
p.m. noon (Chicago time) at least one (1) Business Day before the Borrowing Date
of each Floating Rate Advance (other than a Swing Loan), three (3) Business Days
before the Borrowing Date for each Eurodollar Advance, and on the Borrowing Date
for a Swing Loan, specifying:

         (i) the Borrowing Date, which shall be a Business Day, of such Advance,

         (ii) the aggregate amount of such Advance,

         (iii) the Type of Advance selected, and

         (iv) in the case of each Eurodollar Advance, the Interest Period
applicable thereto.

Not later than 12:00 p.m. noon (Chicago time) on each Borrowing Date (other than
with respect to a Borrowing Notice for a Swing Loan), each Lender shall make
available its Loan or Loans in funds immediately available in Chicago to the
Agent at its address specified pursuant to Article XIII. Not later than 3:00
p.m. (Chicago time) on each Borrowing Date for a Swing Loan, the Agent shall
make available its Swing Loan or Swing Loans in funds immediately available in
Chicago to the Borrower. The Agent will make the funds so received from the
Lenders available to the Borrower at the Agent's aforesaid address.

         2.10. Conversion and Continuation of Outstanding Advances. Floating
Rate Advances shall continue as Floating Rate Advances unless and until such
Floating Rate Advances are converted into Eurodollar Advances pursuant to this
Section 2.10 or are repaid in accordance with Section 2.07. Each Eurodollar
Advance shall continue as a Eurodollar Advance until the end of the then
applicable Interest Period therefor, at which time such Eurodollar Advance shall
be automatically converted into a Floating Rate Advance unless (x) such
Eurodollar Advance is or was repaid in accordance with Section 2.08 or (y) the
Borrower shall have given the Agent a Conversion/Continuation Notice (as defined
below) requesting that, at the end of such Interest Period, all or a portion of
the outstanding principal amount of such Eurodollar Advance continue as a
Eurodollar Advance for the same or another Interest Period. Subject to the terms
of Section 2.06, the Borrower may elect from time to time to convert all or any
part of a Floating Rate Advance into a Eurodollar Advance. The Borrower shall
give the Agent irrevocable notice (a "Conversion/Continuation Notice") in the
form of Exhibit C of each conversion of a Floating Rate Advance into a
Eurodollar Advance or continuation of a Eurodollar Advance not later than 12:00
p.m. noon (Chicago time) at least three (3) Business Days prior to the date of
the requested conversion or continuation, specifying:


                                       21
   28




         (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

         (iii)    the amount of such Advance which is to be converted into or
                  continued as a Eurodollar Advance and the duration of the
                  Interest Period applicable thereto;

provided, that no Advances may be converted into or continued as a Eurodollar
Advance if a Default is in existence on or an Unmatured Default existed thirty
(30) days prior to the date of the proposed conversion or continuation, provided
further that any Advance that is converted into or continued as an Eurodollar
Advance shall not have an Interest Period greater than one month.

         2.11. Changes in Interest Rate, etc. Each Floating Rate Advance shall
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 2.10, to but
excluding the date it is paid or is converted into a Eurodollar Advance pursuant
to Section 2.10, at a rate per annum equal to 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. 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 Agent as applicable to
such Eurodollar Advance based upon the Borrower's selections under Sections 2.09
and 2.10 and otherwise in accordance with the terms hereof. No Interest Period
may end after the Facility Termination Date.

         2.12. Rates Applicable After Default. Notwithstanding anything to the
contrary contained in Section 2.09 or 2.10, during the continuance of a Default
or on and after the thirtieth day of a continuing Unmatured Default, no Advance
may be made as, converted into or continued as a Eurodollar Advance. During the
continuance of a Default or Unmatured Default the Required Lenders may, at their
option, by notice to the Borrower (which notice may be revoked at the option of
the Required Lenders notwithstanding any provision of Section 8.03 requiring
unanimous consent of the Lenders to changes in interest rates), declare that (i)
each outstanding Eurodollar Advance shall bear interest for the remainder of the
applicable Interest Period at the rate otherwise applicable to such Interest
Period plus two percent (2%) per annum, (ii) each Floating Rate Advance and each
Swing Loan shall bear interest at a rate per annum equal to the Floating Rate in
effect from time to time plus two percent (2%) per annum, and (iii) the LC Fee
shall be increased by two percent (2%) per annum; provided that, during the
continuance of a Default under Section 7.06 or 7.07, 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 Agent or any Lender.

         2.13. Method of Payment. All payments of the Obligations hereunder
shall be made, without setoff, deduction, or counterclaim, in immediately
available funds to the Agent at the


                                       22
   29




Agent's address specified pursuant to Article XIII, or at any other Lending
Installation of the Agent specified in writing by the Agent to the Borrower, by
12:00 p.m. noon (Chicago time) on the date when due and shall (except in the
case of Reimbursement Obligations for which the LC Issuer has not been fully
indemnified by the Lenders, or as otherwise specifically required hereunder) be
applied ratably by the Agent among the Lenders. Each payment delivered to the
Agent for the account of any Lender shall be delivered promptly by the Agent to
such Lender in the same type of funds that the Agent received at its address
specified pursuant to Article XIII or at any Lending Installation specified in a
notice received by the Agent from such Lender. The Agent is hereby authorized to
charge the account of the Borrower maintained with First Chicago for each
payment of principal, interest, Reimbursement Obligations and fees as it becomes
due hereunder. Each reference to the Agent in this Section 2.13 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 Borrower to the LC Issuer pursuant to
Section 2.20.06.

         2.14. 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 Borrower to such Lender resulting from each
Loan made by such Lender from time to time, including the amounts of principal
and interest payable and paid to such Lender from time to time hereunder.

         (ii) The Agent shall also maintain accounts in which it will record (a)
the amount of each Loan made hereunder, the Type thereof and the Interest Period
with respect thereto, (b) the amount of any principal or interest due and
payable or to become due and payable from the Borrower to each Lender hereunder,
(c) the original stated amount of each Facility LC and the amount of LC
Obligations outstanding at any time, and (d) the amount of any sum received by
the Agent hereunder from the Borrower and each Lender's share thereof. The
Borrower's obligation on the Swing Loans shall be recorded as loans and advances
made by the Agent in accordance with its customary accounting practices. The
Agent is authorized to record advances and interest on the Swing Loans and
repayments of the Swing Loans in its books and records and the net balance
reflected in such records shall be controlling absent manifest error as to the
Borrower's indebtedness with respect to Swing Loans.

         (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, absent manifest error; provided,
however, that the failure of the Agent or any Lender to maintain such accounts
or any error therein shall not in any manner affect the obligation of the
Borrower to repay the Obligations in accordance with their terms.

         (iv) Any Lender may request that its Loans be evidenced by a promissory
note (a "Note"). In such event, the Borrower shall execute and deliver to such
Lender a Note payable to the order of such Lender. Thereafter, the Loans
evidenced by such Note and interest thereon shall at all times (including after
any assignment pursuant to Section 12.03) be represented by one or more Notes
payable to the order of the payee named therein or any assignee pursuant to
Section 12.03, 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 paragraphs (i) and (ii) above.


                                       23
   30




         2.15. Telephonic Notices. The Borrower hereby authorizes the Lenders
and the 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 Agent or any Lender in good faith believes to be acting on
behalf of the Borrower, it being understood that the foregoing authorization is
specifically intended to allow Borrowing Notices and Conversion/Continuation
Notices to be given telephonically. The Borrower agrees to deliver promptly to
the Agent a written confirmation, if such confirmation is requested by the 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 Agent and the Lenders, the records of the Agent and the Lenders shall govern
absent manifest error.

         2.16. 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; provided that interest on
Floating Rate Advances shall be calculated for actual days elapsed on the basis
of a 365 days 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 12:00 p.m. noon (Chicago 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.

         2.17. Notification of Advances, Interest Rates, Prepayments and
Commitment Reductions. Promptly after receipt thereof, the Agent will notify
each Lender of the contents of each Aggregate Commitment reduction notice,
Borrowing Notice, Conversion/Continuation Notice, and repayment notice received
by it hereunder. Promptly after notice from the LC Issuer, the Agent will notify
each Lender of the contents of each request for issuance of a Facility LC
hereunder. The 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.

         2.18. 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 Agent and the Borrower in accordance with
Article XIII, designate replacement or additional Lending Installations through
which Loans


                                       24
   31




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.

         2.19. Non-Receipt of Funds by the Agent. Unless the Borrower or a
Lender, as the case may be, notifies the Agent prior to the date on which it is
scheduled to make payment to the Agent of (i) in the case of a Lender, the
proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal,
interest or fees to the Agent for the account of the Lenders, that it does not
intend to make such payment, the Agent may assume that such payment has been
made. The 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 the Borrower, as the case may be, has not in fact made such
payment to the Agent on or before when such payment is due, the recipient of
such payment shall, on demand by the Agent, repay to the 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 Agent
until the date the 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 Business Day and, thereafter, the interest rate applicable to
the relevant Loan or (y) in the case of payment by the Borrower, the interest
rate applicable to the relevant Loan. Nothing herein shall be deemed to relieve
any Lender or the Borrower, as the case may be, from its obligations hereunder
or to prejudice any rights any party hereto may have against such Lender or
Borrower as a result of any default by such Lender or Borrower, respectively.

         2.20. Facility LCs.

                  2.20.01. Issuance. 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 LC
         ("Modify," and each such action a "Modification"), from time to time
         from and including the date hereof and prior to the Facility
         Termination Date upon the request of the Borrower; provided that after
         giving effect to each such issued or Modified Facility LC (i) the
         aggregate amount of the outstanding LC Obligations shall not exceed
         $5,000,000 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.

                  2.20.02. Participations. Upon the issuance or Modification by
         the LC Issuer of a Facility LC in accordance with this Section 2.20,
         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.

                  2.20.03. Notice. Subject to Section 2.20.01, the Borrower
         shall give the LC Issuer notice prior to 12:00 p.m. noon (Chicago time)
         at least three (3) Business Days prior to the proposed date of issuance
         or Modification of each Facility LC, specifying the


                                       25
   32




         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 Agent, and the 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 (i) that such Facility LC shall be satisfactory to
         the LC Issuer and (ii) that the 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
         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.

                  2.20.04. LC Fees. The Borrower shall pay to the Agent, for the
         account of the Lenders ratably in accordance with their respective Pro
         Rata Shares, with respect to each 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 Facility LC, such fee ("LC Fee") to be payable in arrears on
         each Payment Date. The 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 agreed upon between the LC Issuer and the
         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.

                  2.20.05. 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 Agent
         and the Agent shall promptly notify the 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 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 Borrower pursuant to Section 2.20.06
         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.
         (Chicago 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


                                       26
   33




         Rate for the first three days and, thereafter, at a rate of interest
         equal to the rate applicable to Floating Rate Advances.

                  2.20.06. Reimbursement by Borrower. The Borrower shall be
         irrevocably and unconditionally obligated to reimburse the LC Issuer on
         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 Borrower nor any Lender shall hereby be precluded from asserting
         any claim for direct (but not consequential) damages suffered by the
         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 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
         two percent (2%) per annum 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 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 2.20.05. Subject to the terms and
         conditions of this Agreement (including without limitation the
         submission of a Borrowing Notice in compliance with Section 2.09 and
         the satisfaction of the applicable conditions precedent set forth in
         Article IV), the Borrower may request an Advance hereunder for the
         purpose of satisfying any Reimbursement Obligation.

                  2.20.07. Obligations Absolute. The Borrower's obligations
         under this Section 2.20 shall be absolute and unconditional under any
         and all circumstances and irrespective of any setoff, counterclaim or
         defense to payment which the Borrower may have or have had against the
         LC Issuer, any Lender or any beneficiary of a Facility LC. The Borrower
         further agrees with the LC Issuer and the Lenders that the LC Issuer
         and the Lenders shall not be responsible for, and the 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 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 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 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 or
         willful


                                       27
   34




         misconduct, shall be binding upon the Borrower and shall not put the LC
         Issuer or any Lender under any liability to the Borrower. Nothing in
         this Section 2.20.07 is intended to limit the right of the Borrower to
         make a claim against the LC Issuer for damages as contemplated by the
         proviso to the first sentence of Section 2.20.06.

                  2.20.08. 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 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 2.20, 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 pursuant thereto shall be binding upon the Lenders and any future
         holders of a participation in any Facility LC.

                  2.20.09. Indemnification. The Borrower hereby agrees to
         indemnify and hold harmless each Lender, the LC Issuer and the Agent,
         and their respective directors, officers, agents and employees from and
         against any and all claims and damages, losses, liabilities, costs or
         expenses which such Lender, the LC Issuer or the Agent may incur (or
         which may be claimed against such Lender, the LC Issuer or the 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 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 Borrower
         shall not be required to indemnify any Lender, the LC Issuer or the
         Agent for any claims, damages, losses, liabilities, costs or expenses
         to the extent, but only to the extent, caused by (x) the willful
         misconduct 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 2.20.09 is intended to limit the obligations of the
         Borrower under any other provision of this Agreement.


                                       28
   35




                  2.20.10. 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 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 2.20 or any action taken or omitted by such
         indemnitees hereunder.

                  2.20.11. Facility LC Collateral Account. The Borrower agrees
         that it will, upon the request of the 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 collateral account
         pursuant to arrangements satisfactory to the Agent (the "Facility LC
         Collateral Account") at the Agent's office at the address specified
         pursuant to Article XIII, in the name of such Borrower but under the
         sole dominion and control of the Agent, for the benefit of the Lenders
         and in which such Borrower shall have no interest other than as set
         forth in Section 8.01. The Borrower hereby pledges, assigns and grants
         to the Agent, on behalf of and for the ratable benefit of the Lenders
         and the LC Issuer, a security interest in all of the 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 Agent will
         invest any funds on deposit from time to time in the Facility LC
         Collateral Account in certificates of deposit of First Chicago having a
         maturity not exceeding 30 days. Nothing in this Section 2.20.11 shall
         either obligate the Agent to require the Borrower to deposit any funds
         in the Facility LC Collateral Account or limit the right of the Agent
         to release any funds held in the Facility LC Collateral Account in each
         case other than as required by Section 8.01.

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

         2.21. Replacement of Lender. If the Borrower is required pursuant to
Section 3.01, 3.02 or 3.05 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 3.03
(any Lender so affected an "Affected Lender"), the Borrower may elect, if such
amounts have been paid within ninety days of such election or 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 Borrower and the Agent
shall agree, as of such date, to purchase for cash the Advances and other
Obligations due to the Affected Lender pursuant to an Assignment Agreement 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 12.03 applicable to assignments, and
(ii) the Borrower shall pay to such


                                       29
   36




Affected Lender in same day funds on the day of such replacement all interest,
fees and other amounts then accrued but unpaid to such Affected Lender by the
Borrower hereunder to and including the date of termination, including without
limitation payments due to such Affected Lender under Sections 3.01, 3.02 and
3.05. Nothing herein shall be deemed to relieve any Lender or the Borrower, as
the case may be, from its obligations hereunder or to prejudice any rights any
party hereto may have against such Lender or Borrower as a result of any default
by such Lender or Borrower, respectively.

                                   ARTICLE III
                             CHANGE IN CIRCUMSTANCES


         3.01. Yield Protection. On or after the date hereof, if 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
after the date hereof 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 after the date
hereof 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 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


                                       30

   37




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 (5) five Business Days of demand by such
Lender or the LC Issuer, the Borrower shall pay such Lender or LC Issuer, as the
case may be, such additional amount or amounts as will compensate such Lender or
the LC Issuer, for such increased cost or reduction in amount received. A
certificate of the Lender (i) stating that the compensation sought to be
recovered hereunder is generally being charged to other customers of such Lender
and (ii) setting forth in reasonable detail such amount or amounts as shall be
necessary to compensate to such Letter for any of the foregoing, shall be
conclusive absent manifest error. The Borrower shall not be obligated to pay
reimbursement compensation to any Lender for additional costs under this Section
3.01 incurred or accrued more than two hundred seventy (270) days prior to the
date that such Lender or the Agent notifies the Borrower thereof.

         3.02. 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 (defined below), then, within (5) Business Days of
demand by such Lender or the LC Issuer, the Borrower 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). A certificate of the Lender
(i) stating that the compensation sought to be recovered hereunder is generally
being charged to other customers of such Lender and (ii) setting forth in
reasonable detail such amount or amounts as shall be necessary to compensate to
such Letter for such Change, shall be conclusive absent manifest error. The
Borrower shall not be obligated to pay reimbursement compensation to any Lender
for additional costs under this Section 3.02 incurred or accrued more than two
hundred seventy (270) days prior to the date that such Lender or the Agent
notifies the Borrower thereof. "Change" means (i) any change after the date
hereof in the Risk-Based Capital Guidelines (defined below) 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 hereof 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 hereof, 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 hereof.

         3.03. 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


                                       31
   38




making or maintaining Eurodollar Advances, then the 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 3.04.

         3.04. 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 Borrower for any reason other
than default by the Lenders, the Borrower will indemnify each Lender for any
loss in the nature of breakage costs, expense or cost incurred by it resulting
therefrom, including, without limitation, any loss, expense or cost in
liquidating or employing deposits acquired to fund or maintain such Eurodollar
Advance.

         3.05. Taxes. (i) All payments by the Borrower to or for the account of
any Lender, the LC Issuer or the 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 Borrower 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
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 3.05) such Lender or the 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 Borrower shall make such deductions, (c) the
Borrower shall pay the full amount deducted to the relevant authority in
accordance with applicable law and (d) the Borrower shall furnish to the Agent
the original copy of a receipt evidencing payment thereof within 30 days after
such payment is made.

         (ii) In addition, the Borrower hereby agrees 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) The Borrower hereby agrees to indemnify the 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 3.05) paid by the 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 Agent, the LC Issuer or such Lender makes demand therefor pursuant
to Section 3.06.

         (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 less than ten (10) Business Days after the date hereof, (i) deliver to
each of the Borrower and the Agent two duly completed copies of United States
Internal Revenue Service Form 1001 or 4224, 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 Borrower and the Agent a United States Internal Revenue Form W-8 or W-9,
as the case may be, and certify that it is entitled


                                       32
   39




to an exemption from United States backup withholding tax. Each Non-U.S. Lender
further undertakes to deliver to each of the Borrower and the 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
Borrower or the 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 Borrower and
the 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 Borrower 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 3.05 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 Borrower 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 Borrower (with a copy to the 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 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 Agent of a change in circumstances which rendered its exemption from
withholding ineffective, or for any other reason), such Lender shall indemnify
the Agent fully for all amounts paid, directly or indirectly, by the Agent as
tax, withholding therefor, or otherwise, including penalties and interest, and
including taxes imposed by any jurisdiction on amounts payable to the Agent
under this subsection, together with all costs and expenses related thereto
(including attorneys fees and time charges of attorneys for the Agent, which
attorneys may be employees of the Agent). The obligations of the Lenders under
this Section 3.05(vii) shall survive the payment of the Obligations and
termination of this Agreement.

         3.06. 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


                                       33
   40




reduce any liability of the Borrower to such Lender under Sections 3.01, 3.02
and 3.05 or to avoid the unavailability of Eurodollar Advances under Section
3.03, so long as such designation is not, in the judgment of such Lender,
disadvantageous to such Lender. Each Lender shall deliver a written statement of
such Lender to the Borrower (with a copy to the Agent) as to the amount due, if
any, under Section 3.01, 3.02, 3.04 or 3.05. 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 Borrower 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 on demand after receipt by the Borrower
of such written statement. The obligations of the Borrower under Sections 3.01,
3.02, 3.04 and 3.05 shall survive payment of the Obligations and termination of
this Agreement.

                                   ARTICLE IV
                              CONDITIONS PRECEDENT

         4.01. Initial Credit Extension. The obligation of each Lender to make
its initial Credit Extension hereunder is subject to the conditions that such
Credit Extension occurs on or before May 31, 1999 and that the Borrower has
furnished to the Agent with sufficient copies for the Lenders, each dated the
date hereof and in form and substance satisfactory to the Agent, the following:

                  payable to the order of each such requesting Lender in the
                  face amount of the Commitment of such Lender.

         (iii)    The Guaranties, each one duly executed by the respective
                  Guarantors, together with a solvency certificate duly executed
                  by the Borrower and the respective Guarantors.

         (iv)     The Security Agreements, each one duly executed by the
                  respective Pledgors or the Borrower.

         (v)      The Stock Pledge Agreement, duly executed by Borrower together
                  with the stock certificates and instruments described in the

                  certificates, accompanied by appropriate stock powers).

         (vi)     The Note Pledge Agreements duly executed by Borrower, together
                  with the intercompany promissory notes and other instruments

   43

         (ii) The representations and warranties contained in Article V are true
and correct as of such Credit Extension Date except to the extent any such

and as of such earlier date.

         Each Borrowing Notice, Conversion/Continuation Note, or request for the
issuance or Modification of a Facility LC with respect to each such Credit
Extension shall constitute a representation and warranty by the Borrower that
the conditions contained in Sections 4.02(i) and 4.02(ii) have been satisfied as

                                    ARTICLE V
                         REPRESENTATIONS AND WARRANTIES

         In order to induce the Agent and the Lenders to enter into this
Agreement and to make the Advances provided for herein, the Borrower for itself
and each of its Subsidiaries (including, on the Founding Company Acquisition
Date, each Founding Company as if it were already acquired), on or as of the
occurrence of each Credit Extension (except to the extent such representation or
warranty expressly relate to an earlier date), represents and warrants to the
Agent and the Lenders that:

         5.01. Existence and Standing. Each of the Borrower and its Subsidiaries
is a corporation, partnership (in the case of Subsidiaries only) or limited
liability company 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 and has all requisite authority to conduct its business in each
jurisdiction in which its business is conducted.

         5.02. Authorization and Validity. The Borrower has the 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 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 Borrower is a party constitute
legal, valid and binding obligations of the Borrower enforceable against the
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.

         5.03. No Conflict; Government Consent. Neither the execution and
delivery by the 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 Borrower or any of its
Subsidiaries or (ii) the Borrower's or any Subsidiary's articles or certificate
of incorporation, partnership agreement, certificate of partnership, articles or
certificate of organization, by-laws, or


                                       37

   44




operating or other management agreement, as the case may be, or (iii) the
provisions of any indenture, instrument or agreement to which the 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 Borrower or any of its Subsidiaries 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 Borrower or any of its Subsidiaries, is required to be
obtained by the 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 Borrower of the Obligations or the
legality, validity, binding effect or enforceability of any of the Loan
Documents.

         5.04. Financial Statements. The consolidated financial statements of
the 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 Borrower and its Subsidiaries at such
date and the consolidated results of their operations for the period then ended.

         5.05. Material Adverse Change. Since September 30, 1998 there has been
no change in the business, Property, operations, performance, condition
(financial or otherwise) or results of operations of the Borrower and its
Subsidiaries which could have a Material Adverse Effect.

         5.06. Taxes. The 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 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 GAAP and as to which no Lien
exists. No tax liens have been filed and no claims are being asserted with
respect to any such taxes. The charges, accruals and reserves on the books of
the Borrower and its Subsidiaries in respect of any taxes or other governmental
charges are adequate. If any Subsidiary of the Borrower is a limited liability
company, each such limited liability company qualifies for partnership tax
treatment under United States federal tax law.

         5.07. 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
Borrower or any of its Subsidiaries which could have a Material Adverse Effect
or which seeks to prevent, enjoin or delay the making of any Credit Extension.
Other than any liability incident to any litigation, arbitration or proceeding
which could not have a Material Adverse Effect, the Borrower has no material
contingent obligations not provided for or disclosed in the financial statements
referred to in Section 5.04.

         5.08. Subsidiaries. Schedule III contains an accurate list of all
Subsidiaries of the Borrower as of the date hereof, setting forth their
respective jurisdictions of organization and the percentage of their respective
capital stock or other ownership interests owned by the Borrower or other


                                       38

   45



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.

         5.09. ERISA. To the extent that none of the following could have a
Material Adverse Effect, (i) the Unfunded Liabilities of all Single Employer
Plans are non-existent or minimal could not have a Material Adverse Effect; (ii)
neither the Borrower nor any other member of the Controlled Group has incurred,
or is expected to incur, any withdrawal liability to Multiemployer Plans; (iii)
each Plan complies in all material respects with all applicable requirements of
law and regulations, no Reportable Event has occurred with respect to any Plan,
neither the Borrower nor any other member of the Controlled Group has withdrawn
from any Plan or initiated steps to do so, and no steps have been taken to
reorganize or terminate any Plan.

         5.10. Accuracy of Information. No information, exhibit or report
furnished by the Borrower or any of its Subsidiaries to the Agent or to any
Lender in connection with the negotiation of, or compliance with, the Loan
Documents contained any material misstatement of fact or omitted to state a
material fact or any fact necessary to make the statements contained therein,
together with all exhibits, reports and other information furnished to the
Borrower and its Subsidiaries to the Agent and the Lenders, taken as a whole,
not misleading.

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

         5.12. Material Agreements. Neither the Borrower nor any Subsidiary is a
party to any agreement or instrument or subject to any charter or other
corporate restriction which could have a Material Adverse Effect. Neither the
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 have a Material
Adverse Effect or (ii) any one or more agreements or instruments evidencing or
governing Material Indebtedness.

         5.13. Compliance With Laws. The 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 have a Material Adverse
Effect.

         5.14. Ownership of Properties. Except as set forth on Schedule V, on
the date hereof, the 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 Borrower's most recent consolidated financial statements
provided to the Agent as owned by the Borrower and its Subsidiaries.

         5.15. Plan Assets; Prohibited Transactions. The Borrower is not an
entity deemed to hold "plan assets" within the meaning of 29 C.F.R. Section
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


                                       39

   46




Section 4975 of the Code), "benefit plan investors" (as defined in 29 C.F.R.
Section 2510.3-101(f)) do not own twenty-five percent (25%) or more of the value
of any class of equity interests in the Borrower and neither the execution of
this Agreement nor the making of any Credit Extension hereunder gives rise to a
prohibited transaction within the meaning 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 Borrower consider the effect of Environmental Laws on the
business of the Borrower and its Subsidiaries, in the course of which they
identify and evaluate potential risks and liabilities accruing to the Borrower
due to Environmental Laws. On the basis of this consideration, the Borrower has
concluded that Environmental Laws do not have a Material Adverse Effect. Neither
the Borrower nor any Subsidiary has received any notice to the effect that its
operations are not in 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 have a Material Adverse Effect.

         5.17. Investment Company Act. Neither the Borrower nor any Subsidiary
is an "investment company" or a company "controlled" by an "investment company",
within the meaning of the Investment Company Act of 1940, as amended.

         5.18. Public Utility Holding Company Act. Neither the Borrower nor any
Subsidiary is a "holding company" or a "subsidiary company" of a "holding
company", or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company", within the meaning of the Public Utility Holding Company
Act of 1935, as amended.

         5.19. Year 2000. The Borrower has made a full and complete assessment
of the Year 2000 Issues and has a realistic and achievable program for
remediating the Year 2000 Issues on a timely basis (the "Year 2000 Program").
Based on such assessment and on the Year 2000 Program the Borrower does not
reasonably anticipate that Year 2000 Issues will have a Material Adverse Effect.

         5.20. Subordinated Debt. The Obligations constitute senior indebtedness
which is entitled to the benefits of the subordination provisions of all
outstanding Subordinated Debt.

         5.22. Insurance. The certificate signed by the President or Chief
Financial Officer of the Borrower, that attests to the existence and adequacy
of, and summarizes, the property and casualty insurance program carried by the
Borrower with respect to itself and its Subsidiaries and that has been furnished
by the Borrower to the Agent and the Lenders, is complete and accurate. This
summary includes the insurer's or insurers' name(s), policy number(s),
expiration date(s), amount(s) of coverage, type(s) of coverage, exclusion(s),
and deductibles. This summary also includes similar information, and describes
any reserves, relating to any self-insurance program that is in effect.

         5.23. Solvency. (i) Immediately after the consummation of the
transactions to occur on the date hereof and immediately following the making of
each Loan, if any, made on the date hereof and after giving effect to the
application of the proceeds of such Loans, (a) the fair value of the business


                                       40
   47




of the Borrower and its Subsidiaries on a consolidated basis, will exceed the
debts and liabilities, subordinated, contingent or otherwise, of the Borrower
and its Subsidiaries on a consolidated basis; (b) the present fair saleable
value of the Property of the Borrower and its Subsidiaries on a consolidated
basis will be greater than the amount that will be required to pay the probable
liability of the 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 Borrower and
its Subsidiaries on a consolidated basis expect to be able to pay their debts
and liabilities, subordinated, contingent or otherwise, as such debts and
liabilities become absolute and matured; and (d) the Borrower and its
Subsidiaries on a consolidated basis believe that it does 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 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.

         5.24. General Purpose of Facility. The Borrower warrants and represents
to the Agent the LC Issuer and the Lenders and all other future owners and
holders of this Agreement, the Notes and the other Loan Documents, that all
Credit Extensions are and will be for business, commercial, investment or other
similar purpose and not primarily for personal, family, household or
agricultural use, as such terms are used in Chapter 1D or in the Texas Finance
Code.


                                   ARTICLE VI
                                    COVENANTS

the Borrower hereunder or under any Note shall remain unpaid or any Lender shall

otherwise consent in writing:

         6.01. Financial and Other Reporting. The Borrower will maintain, for
itself and each Subsidiary, a system of accounting established and administered

                                  ARTICLE VIII
                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

         8.01. Acceleration; Facility LC Collateral Account. (i) If any Default
described in Section 7.06 or 7.07 occurs with respect to the Borrower, 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 Agent, the LC Issuer or any Lender, and the Borrower
will be and become thereby unconditionally obligated, without any further
notice, act or demand, to pay to the 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 minus (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 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 Agent with
the consent of the Required Lenders) may (a) terminate or suspend the
obligations of the Lenders to make Loans hereunder, 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 Borrower hereby expressly waives, and (b) upon notice
to the Borrower and in addition to the continuing right to demand payment of all
amounts payable under this Agreement, make demand on the Borrower to pay, and
the Borrower will, forthwith upon such demand and without any further notice or
act, pay to the 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 Agent
determines that the Collateral Shortfall Amount as such time is greater than
zero, the Agent may make demand on the Borrower to pay, and the Borrower will,
forthwith upon such demand and without any further notice or act, pay


                                       51
   58




to the Agent the Collateral Shortfall Amount, which funds shall be deposited in
the Facility LC Collateral Account.

         (iii) The 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 Borrower to the Lenders or the LC Issuer under the Loan
Documents.

         (iv) At any time which any Default is continuing, neither the Borrower
nor any Person claiming on behalf of or through the 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 Agent to the Borrower or paid to
whomever may be legally entitled thereto at such time.

         (v) If, within thirty (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 7.06 or
7.07 with respect to the Borrower) 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 Agent shall, by notice
to the Borrower, rescind and annul such acceleration and/or termination.

         8.02. Other Remedies. If any Default occurs, the Agent may, and upon
the request of the Required Lenders shall, proceed to protect and enforce the
rights of the Agent and the Lenders by suit in equity, by action at law or both,
whether for the specific performance of any covenant or agreement contained in
this Agreement or in any other Loan Document or in aid of the exercise of any
power granted in this Agreement or pursuant to any other Loan Document; or may
proceed to enforce the payment of any amounts outstanding hereunder, under the
Notes and under the other Loan Documents in the manner set forth herein and
therein; or may proceed to foreclose upon any Lines granted pursuant to the
Collateral Documents and other Loan Documents in the manner set forth therein,
it being the intention that no remedy conferred herein or in any other Loan
Document is to be exclusive of any other remedy, and each and every remedy
contained herein or in any other Loan Document shall be cumulative and shall be
in addition to every other remedy given hereunder and under the other Loan
Documents, or now or hereafter existing at law or in equity or by statue or
otherwise.

         8.03. Amendments. Subject to the provisions of this Article VIII, the
Required Lenders (or the Agent with the consent in writing of the Required
Lenders) and the Borrower 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 Borrower hereunder or waiving 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 forgive all or any portion of the
                  principal amount thereof or any Reimbursement Obligation
                  related thereto, or reduce the rate 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.


                                       52
   59




         (iii)    Extend the Facility Termination Date, or reduce the amount or
                  extend the payment date for, the mandatory payments required
                  under Section 2.02, or increase the amount of the Aggregate
                  Commitment, the Commitment of any Lender hereunder or the
                  commitment to issue Facility LCs, or permit the Borrower to
                  assign its rights under this Agreement.

         (iv)     Amend this Section 8.03.

         (v)      Release any guarantor of any Credit Extension or, except as
                  provided in the Collateral Documents, release all or
                  substantially all of the Collateral.

No amendment of any provision of this Agreement relating to the Agent shall be
effective without the written consent of the Agent, and no amendment of any
provision relating to the LC Issuer shall be effective without the written
consent of the LC Issuer. The Agent may waive payment of the fee required under
Section 12.03.02 without obtaining the consent of any other party to this
Agreement.

         8.04. Preservation of Rights. No delay or omission of the Lenders, the
LC Issuer or the 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 Borrower 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 8.03, 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 Agent, the LC Issuer and the Lenders until the Obligations have been paid
in full and all of the Commitments have been terminated.


                                   ARTICLE IX
                               GENERAL PROVISIONS

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

         9.02. 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 the Borrower in violation of any limitation or
prohibition provided by any applicable statute or regulation.

         9.03. 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.

         9.04. Entire Agreement. The Loan Documents embody the entire agreement
and understanding among the Borrower, the Agent, the LC Issuer and the Lenders
and supersede all prior agreements and understandings among the Borrower, the
Agent, the LC Issuer and the Lenders relating to the subject matter thereof
other than the fee letter described in Section 10.13.

         9.05. 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
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


                                       53

   60




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 9.06, 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.

         9.06. Expenses; Indemnification. (i) The Borrower shall reimburse the
Agent and the Arranger for any costs, internal charges and out-of-pocket
expenses (including attorneys' fees and time charges of attorneys for the Agent,
which attorneys may be employees of the Agent) paid or incurred by the Agent or
the Arranger in connection with the preparation, negotiation, execution,
delivery, syndication, review, amendment, modification, and (excluding internal
charges prior to an Unmatured Default) administration of the Loan Documents. The
Borrower also agrees to reimburse the Agent, the Arranger, the LC Issuer and the
Lenders for any costs, internal charges and out-of-pocket expenses (including
attorneys' fees and time charges of attorneys for the Agent, the Arranger, the
LC Issuer and the Lenders, which attorneys may be employees of the Agent, the
Arranger, the LC Issuer or the Lenders) paid or incurred by the 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 Borrower
under this Section 9.06 include, without limitation, costs and expenses incurred
in connection with the Reports described in the following sentence. The Borrower
acknowledges that from time to time First Chicago 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
Borrower's assets for internal use by First Chicago from information furnished
to it by or on behalf of the Borrower, after First Chicago has exercised its
rights of inspection pursuant to this Agreement.

         (ii) THE BORROWER HEREBY FURTHER AGREES TO INDEMNIFY THE 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 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, INCLUDING WITHOUT
LIMITATION, THOSE ARISING OUT OF ORDINARY NEGLIGENCE, 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 OR WILLFUL MISCONDUCT OF
THE PARTY SEEKING INDEMNIFICATION. The obligations of the Borrower under this
Section 9.06 shall survive the termination of this Agreement.

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

         9.08. Accounting. Except as provided to the contrary herein, all
accounting terms used herein shall be interpreted and all accounting
determinations hereunder shall be made in accordance with GAAP.


                                       54

   61




         9.09. Credit Agreement Controls. In the event of any conflict or
inconsistencies among this Agreement and any of the other Loan Documents, the
terms and provisions of this Agreement shall prevail and control.

         9.10. 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.

         9.11. Nonliability of Lenders. The relationship between the Borrower on
the one hand and the Lenders, the LC Issuer and the Agent on the other hand
shall be solely that of borrower and lender. Neither the Agent, the Arranger,
the LC Issuer nor any Lender shall have any fiduciary responsibilities to the
Borrower. Neither the Agent, the Arranger, the LC Issuer nor any Lender
undertakes any responsibility to the Borrower to review or inform the Borrower
of any matter in connection with any phase of the Borrower's business or
operations. The Borrower agrees that neither the Agent, the Arranger, the LC
Issuer nor any Lender shall have liability to the Borrower (whether sounding in
tort, contract or otherwise) for losses suffered by the Borrower 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 or willful misconduct of the party from which
recovery is sought. Neither the Agent, the Arranger, the LC Issuer nor any
Lender shall have any liability with respect to, and the Borrower hereby waives,
releases and agrees not to sue for, any special, indirect or consequential
damages suffered by the Borrower in connection with, arising out of, or in any
way related to the Loan Documents or the transactions contemplated thereby.

         9.12. Confidentiality. Each Lender agrees to hold any confidential
information which it may receive from the Borrower 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 12.04.

         9.13. 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.


                                    ARTICLE X
                                    THE AGENT

         10.01. Appointment; Nature of Relationship. The First National Bank of
Chicago is hereby appointed by each of the Lenders as its contractual
representative (herein referred to as the "Agent") hereunder and under each
other Loan Document, and each of the Lenders irrevocably authorizes the 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 Agent agrees to
act as such contractual representative upon the express conditions contained in
this Article X. Notwithstanding the use of the defined term "Agent," it is
expressly understood and agreed that the Agent shall not have any fiduciary
responsibilities to any Lender by reason of this Agreement or any other Loan
Document and that the Agent is merely acting as the contractual representative
of the Lenders with only those


                                       55

   62




duties as are expressly set forth in this Agreement and the other Loan
Documents. In its capacity as the Lenders' contractual representative, the 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 Agent on any agency theory or any other theory of
liability for breach of fiduciary duty, all of which claims each Lender hereby
waives.

         10.02. Powers. The Agent shall have and may exercise such powers under
the Loan Documents as are specifically delegated to the Agent by the terms of
each thereof, together with such powers as are reasonably incidental thereto.
The 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 Agent.

         10.03. General Immunity. Neither the Agent nor any of its directors,
officers, agents or employees shall be liable to the Borrower, 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 or willful misconduct of such Person.

         10.04. No Responsibility for Loans, Recitals, etc. Neither the 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 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 Borrower or any
guarantor of any of the Obligations or of any of the Borrower's or any such
guarantor's respective Subsidiaries. The Agent shall have no duty to disclose to
the Lenders information that is not required to be furnished by the Borrower to
the Agent at such time, but is voluntarily furnished by the Borrower to the
Agent (either in its capacity as Agent or in its individual capacity).

         10.05. Action on Instructions of Lenders. The 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 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 unless it shall be requested in writing to do so by
the Required Lenders. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN
OR IN ANY OTHER LOAN DOCUMENT, EACH OF THE AGENT AND THE LC ISSUER 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 AGAINST ANY AND ALL LIABILITY, LOSSES, DAMAGES JUDGMENTS, COSTS,
EXPENSES AND DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED
UPON, INCURRED BY OR


                                       56
   63




ASSERTED AGAINST SUCH AGENT OR LC ISSUER IN ANY WAY RELATING TO OR ARISING OUT
OF ITS TAKING OR CONTINUING TO TAKE ANY ACTION.

         10.06. Employment of Agents and Counsel. The Agent may execute any of
its duties as 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 Agent shall be entitled to advice of
counsel concerning the contractual arrangement between the Agent and the Lenders
and all matters pertaining to the Agent's duties hereunder and under any other
Loan Document.

         10.07. Reliance on Documents; Counsel. The 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 Agent, which counsel
may be employees of the Agent.

         10.08. Agent's Reimbursement and Indemnification. The Lenders agree to
reimburse and indemnify the 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 Borrower for which the Agent is entitled to reimbursement by
the Borrower under the Loan Documents, (ii) for any other expenses incurred by
the 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 Agent in
connection with any dispute between the 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 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 Agent in connection with any dispute
between the 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 Agent and (ii) any indemnification required
pursuant to Section 3.05(vii) shall, notwithstanding the provisions of this
Section 10.08, be paid by the relevant Lender in accordance with the provisions
thereof. The obligations of the Lenders under this Section 10.08 shall survive
payment of the Obligations and termination of this Agreement.

         10.09. Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Unmatured Default
hereunder unless the Agent has received written notice from a Lender or the
Borrower 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 Agent receives such a notice, the Agent shall give prompt notice thereof to
the Lenders.

         10.10. Rights as a Lender. In the event the Agent is a Lender, the
Agent shall have the same rights and powers hereunder and under any other Loan
Document with respect to its Commitment and its Loans as any Lender and may
exercise the same as though it were not the Agent, and the term "Lender" or
"Lenders" shall, at any time when the Agent is a Lender, unless the context
otherwise indicates, include the Agent in its individual capacity. The 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


                                       57

   64




the Borrower or any of its Subsidiaries in which the Borrower or such Subsidiary
is not restricted hereby from engaging with any other Person. The Agent, in its
individual capacity, is not obligated to remain a Lender.

         10.11. Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Agent, the Arranger or any other
Lender and based on the financial statements prepared by the Borrower 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 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 Agent. The Agent may resign at any time by giving
written notice thereof to the Lenders and the Borrower, such resignation to be
effective upon the appointment of a successor Agent or, if no successor Agent
has been appointed, forty-five days after the retiring Agent gives notice of its
intention to resign. The Agent may be removed at any time with or without cause
by written notice received by the 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 Borrower (if no Default or Unmatured Default shall
exist) and the Required Lenders shall have the right to appoint, on behalf of
the Borrower and the Lenders, a successor Agent. If no successor Agent shall
have been so appointed by the Borrower (if applicable) and the Required Lenders
within thirty days after the resigning Agent's giving notice of its intention to
resign, then the resigning Agent may appoint, on behalf of the Borrower and the
Lenders, a successor Agent. Notwithstanding the previous sentence, the Agent may
at any time without the consent of the Borrower or any Lender, appoint any of
its Affiliates which is a commercial bank as a successor Agent hereunder. If the
Agent has resigned or been removed and no successor Agent has been appointed,
the Lenders may perform all the duties of the Agent hereunder and the Borrower
shall make all payments in respect of the Obligations to the applicable Lender
and for all other purposes shall deal directly with the Lenders. No successor
Agent shall be deemed to be appointed hereunder until such successor Agent has
accepted the appointment. Any such successor Agent shall be a commercial bank
having capital and retained earnings of at least $100,000,000. Upon the
acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the resigning or removed Agent. Upon
the effectiveness of the resignation or removal of the Agent, the resigning or
removed 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 Agent, the provisions of this Article X shall continue in effect for the
benefit of such Agent in respect of any actions taken or omitted to be taken by
it while it was acting as the Agent hereunder and under the other Loan
Documents. In the event that there is a successor to the Agent by merger, or the
Agent assigns its duties and obligations to an Affiliate pursuant to this
Section 10.12, then the term "Corporate Base Rate" as used in this Agreement
shall mean the prime rate, base rate or other analogous rate of the new Agent.

         10.13. Agent's Fee. The Borrower agrees to pay to the Agent and the LC
Issuer, for their own respective accounts, the fees agreed to by the Borrower
pursuant to that certain fee letter agreement dated March 10, 1999 among the
Borrower, the Arranger and Bank One, Texas, N.A. on behalf of the Agent, or as
otherwise agreed from time to time.

         10.14. Delegation to Affiliates. The Borrower and the Lenders agree
that the 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 Agent is entitled under Articles IX and X.


                                       58

   65




         10.15. Execution of Collateral Documents. The Lenders hereby empower
and authorize the Agent to execute and deliver to the Borrower on their behalf
the Collateral Documents and all related financing statements and any financing
statements, agreements, documents or instruments as shall be necessary or
appropriate to effect the purposes of the Collateral Documents.

         10.16. Collateral Releases. The Lenders hereby empower and authorize
the Agent to execute and deliver to the Borrower on their behalf any agreements,
documents or instruments as shall be necessary or appropriate to effect any
releases of Collateral which shall be permitted by the terms hereof or of any
other Loan Document or which shall otherwise have been approved by the Required
Lenders (or, if required by the terms of Section 8.03, all of the Lenders) in
writing, and in each case all other action reasonably incidental thereto.

         10.17. Documentary Agent. The Lender that is the Documentation Agent
shall not have any right, power, obligation, liability, responsibility or duty
under this Agreement other than those applicable to all Lenders generally.
Without limiting the foregoing, no Lender shall have or be deemed to have a
fiduciary relationship with any other Lender. Each Lender hereby makes the same
acknowledgments with respect to such Lenders as it makes with respect to the
Agent in Section 10.11.

         10.18. Highest Lawful Rate. Each provision in this Agreement and each
other Loan Document is expressly limited so that in no event whatsoever shall
the amount paid, or otherwise agreed to be paid, to the Agent, the LC Issuer or
any Lender for the use, forbearance or detention of the money to be loaned under
this Agreement or any Loan Document or otherwise (including any sums paid as
required by any covenant or obligation contained herein or in any other Loan
Document which is for the use, forbearance or detention of such money), exceed
that amount of money which would cause the effective rate of interest to exceed
the Highest Lawful Rate, and all amounts owed under this Agreement and each
other Loan Document shall be held to be subject to reduction to the effect that
such amounts so paid or agreed to be paid which are for the use, forbearance or
detention of money under this Agreement or such Loan Document shall in no event
exceed that amount of money which would cause the effective rate of interest to
exceed the Highest Lawful Rate. Anything in this Agreement, any Note or any
other Loan Document would exceed the Highest Lawful Rate or if the holder of
such Note shall receive any unearned interest on any Note or ever be required to
pay interest on such Note at a rate in excess of the Highest Lawful Rate, and if
the effective rate of interest which would otherwise be payable under this
Agreement, such Note or any other Loan Document would exceed the Highest Lawful
Rate, or if the holder of such Note shall receive any unearned interest or shall
receive monies that are deemed to constitute interest which would increase the
effective rate of interest payable by the Borrower under this Agreement, such
Note and the other Loan Documents to a rate in excess of the Highest Lawful
Rate, then (i) the amount of interest which would otherwise be payable by the
Borrower under this Agreement, such Note and other Loan Documents shall be
reduced to the amount allowed under applicable law, and (ii) any unearned
interest paid by the Borrower or any interest paid by the Borrower in excess of
the Highest Lawful Rate shall be in the first instance credited on the principal
of such Note with the excess thereof, if any, refunded to the Company. It is
further agreed that, without limitation of the foregoing, all calculations of
the rate of interest contracted for, charged or received by the Agent, the LC
Issuer or any Lender under the Notes or under this Agreement or the other Loan
Documents, are made for the purpose of determining whether such rate exceeds the
Highest Lawful Rate applicable to the Agent, the LC Issuer or any Lender and
shall be made, to the extent permitted by usury laws applicable to the Agent the
LC Issuer or any Lender (now or hereafter enacted), by amortizing, prorating and
spreading in equal party during the period of the full stated term of the notes
all interest at any time contracted for, charged or received by the Agent, the
LC Issuer or such Lender in connection therewith. If at any time and from time
to time, (i) the amount of interest payable to the Agent, the LC Issuer or any
Lender on any date shall be computed at the Highest Lawful Rate pursuant to this
Section 10.18 and (ii) in respect of any subsequent interest computation period
the amount of interest


                                       59

   66




otherwise payable to the Agent, the LC Issuer or any Lender would be less than
the amount of interest payable to the Agent, the LC Issuer or such Lender, as
the case may be, computed at the Highest Lawful Rate, then the amount of
interest payable to the Agent, the LC Issuer or such Lender, as the case may be,
in respect of such subsequent interest computation period shall continue to be
computed at the Highest Lawful Rate until the total amount of interest payable
to the Agent, the LC Issuer or such Lender, as the case may be, shall equal the
total amount of interest which would have been payable to the Agent, the LC
Issuer or such Lender if the total amount of interest had been computed without
giving effect to this Section 10.18.

         10.19. Chapter 346 Inapplicable. The Borrower agrees, pursuant to
Chapter 346 ("Chapter 346") of the Texas Finance Code, that Chapter 346 (which
relates to open-end line of credit revolving loan accounts) shall not apply to
the Obligations and that none of the Notes nor any Credit Extension shall be
governed by Chapter 346 or subject to its provisions in any manner whatsoever.

                                   ARTICLE XI
                            SETOFF; RATABLE PAYMENTS

         11.01. Setoff. In addition to, and without limitation of, any rights of
the Lenders under applicable law, if the 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 the Borrower may
be offset and applied toward the payment of the Obligations owing to such
Lender, whether or not the Obligations, or any part hereof, shall then be due.

         11.02. 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 3.01, 3.02, 3.04 or 3.05) 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
Shares of the Aggregate Outstanding Credit Exposure. In case any such payment is
disturbed by legal process, or otherwise, appropriate further adjustments shall
be made.


                                   ARTICLE XII
                BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

         12.01. Successors and Assigns. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the
Lenders and their respective successors and assigns, except that (i) the
Borrower shall not 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 12.03. Notwithstanding clause (ii) of this Section 12.01, any
Lender may at any time, without the consent of the Borrower or the Agent, assign
all or any portion of its rights under this Agreement and any Note to a Federal
Reserve Bank; provided, however, that no such assignment to a Federal Reserve
Bank shall release the transferor Lender from its obligations hereunder. The
Agent may treat the Person which made any Loan or which holds any Note as the
owner thereof for all purposes hereof unless and until such Person complies with
Section 12.03 in


                                       60

   67




the case of an assignment thereof or, in the case of any other transfer, a
written notice of the transfer is filed with the Agent. Any assignee or
transferee of the rights to any Loan or any Note agrees by acceptance of such
transfer or 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 Loan (whether or not a Note has been issued in evidence thereof),
shall be conclusive and binding on any subsequent holder, transferee or assignee
of the rights to such Loan.

         12.02. Participations.

                  12.02.1. 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 Eligible Institutions
         ("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 Borrower under this Agreement shall be determined as if such
         Lender had not sold such participating interests, and the Borrower and
         the Agent shall continue to deal solely and directly with such Lender
         in connection with such Lender's rights and obligations under the Loan
         Documents.

                  12.02.2. 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 Loan 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 or, except in accordance with the terms
         hereof, releases all or substantially all of the Collateral, if any,
         securing any such Credit Extension.

                  12.02.3. Benefit of Setoff. The Borrower agrees that each
         Participant shall be deemed to have the right of setoff provided in
         Section 11.01 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 11.01 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 11.01, agrees to share with each
         Lender, any amount received pursuant to the exercise of its right of
         setoff, such amounts to be shared in accordance with Section 11.02 as
         if each Participant were a Lender.

         12.03.   Assignments.

                  12.03.01. Permitted Assignments. Any Lender may, in accordance
         with applicable law, at any time assign to one or more Eligible
         Institutions ("Purchasers") all or any part of its rights and
         obligations under the Loan Documents. Such assignment


                                       61

   68




         ("Assignment Agreement") shall be substantially in the form of Exhibit
         J or in such other form as may be agreed to by the parties thereto. The
         consent of the Borrower and the Agent 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 Borrower 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 Borrower and
         the 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 Loans (if the applicable Commitment has been terminated).

                  12.03.02. Effect; Effective Date. Upon (i) delivery to the
         Agent of an assignment, together with any consents required by Section
         12.03.01, and (ii) payment of a $3,500 fee to the Agent for processing
         such assignment (unless such fee is waived by the Agent), such
         assignment shall become effective on the effective date specified in
         such assignment. The assignment shall contain a representation by the
         Purchaser 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 constitutes "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 Borrower, the Lenders or the 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 12.03.02, the transferor Lender,
         the Agent and the Borrower 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 Purchaser, in
         each case in principal amounts reflecting their respective Commitments,
         as adjusted pursuant to such assignment.

         12.04. Dissemination of Information. The Borrower authorizes each
Lender to disclose to any Participant or Purchaser or any other Eligible
Institution 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 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.

         12.05. 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 3.05(iv).


                                       62

respect to Borrowing Notices and Conversion/Continuation Notices, all notices,

Lending Installation Schedule or (z) in the case of any party, at such other
address or facsimile number as such party may hereafter specify for the purpose
by notice to the Agent and the Borrower in accordance with the provisions of
this Section 13.01. Each such notice, request or other communication shall be
effective (i) if given by facsimile transmission, when transmitted to the
facsimile number specified in this Section 13.01 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 the address specified in this Section 13.01; provided
that notices to the Agent under Article II shall not be effective until
received.

         13.02. Change of Address. The Borrower, the Agent and any Lender may
each change the address for service of notice upon it by a notice in writing to
the other parties hereto.


                                   ARTICLE XIV
                                  COUNTERPARTS

         This Agreement may be executed in any number of counterparts, all of
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 Borrower, the
Agent and the Lenders, the LC Issuer and each party has notified the Agent by
facsimile transmission or telephone that it has taken such action.


                                   ARTICLE XV
                  CHOICE OF LAW; CONSENTS; WAIVER OF JURY TRIAL

         15.01. Choice of Law. THE LOAN DOCUMENTS (OTHER THAN THOSE CONTAINING A
CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH
THE LAW (WITHOUT REGARD TO THE CONFLICT OF LAWS PROVISIONS) OF THE STATE OF
TEXAS, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

         15.02. Consent to Jurisdiction. THE BORROWER HEREBY IRREVOCABLY SUBMITS
TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR STATE COURT
SITTING IN HOUSTON, TEXAS IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING
TO ANY LOAN DOCUMENTS AND THE BORROWER HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS
IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH
COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO
THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT
SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE
AGENT, THE LC ISSUER OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE


                                       63

   70




BORROWER IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY THE
BORROWER AGAINST THE AGENT, THE LC ISSUER OR ANY LENDER OR ANY AFFILIATE OF THE
AGENT, THE LC ISSUER OR ANY LENDER INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER
IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT SHALL
