     2.8. 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. The Borrower
shall give the Agent irrevocable notice (a "Borrowing Notice") not later than
10:00 a.m. (Tulsa time) at least one Business Day before the Borrowing Date of
each Floating Rate Advance (other than a Swing Line Loan) and two (2) Business
Days before the Borrowing Date for each Eurodollar Advance, 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 11:00 a.m. (Tulsa time) on each Borrowing Date, each Lender shall
make available its Loan or Loans in funds immediately available in Tulsa to the
Agent at its address specified pursuant to Article XIII. The Agent will make the
funds so received from the Lenders available to the Borrower at the Agent's
aforesaid address.

     2.9. Conversion and Continuation of Outstanding Advances. Floating Rate
Advances (other than Swing Line Loans) shall continue as Floating Rate Advances
unless and until such Floating Rate Advances are converted into Eurodollar
Advances pursuant to this Section 2.9 or are repaid in accordance with Section
2.7. 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

                                       23



(x) such Eurodollar Advance is or was repaid in accordance with Section 2.7 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, such
Eurodollar Advance continue as a Eurodollar Advance for the same or another
Interest Period. Subject to the terms of Section 2.6, the Borrower may elect
from time to time to convert all or any part of a Floating Rate Advance (other
than Swing Line Loans) into a Eurodollar Advance. The Borrower shall give the
Agent irrevocable notice (a "Conversion/Continuation Notice") of each conversion
of a Floating Rate Advance into a Eurodollar Advance or continuation of a
Eurodollar Advance not later than 10:00 a.m. (Tulsa time) at least two (2)
Business Days prior to the date of the requested conversion or continuation,
specifying:

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

     (ii) the a ggregate 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.

     2.10. Changes in Interest Rate, etc. Each Floating Rate Advance (other than
a Swing Line Loan) 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 2.9, to but excluding the date it is paid or is converted
into a Eurodollar Advance pursuant to Section 2.9 hereof, at a rate per annum
equal to the Floating Rate for such day. Each Swing Line Loan shall bear
interest on the outstanding principal amount thereof, for each day from and
including the day such Swing Line Loan is made to but excluding the date it is
paid, at a rate per annum equal to the Floating Rate for such day, plus the
Applicable Margin set forth on the Pricing Schedule. 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 2.8 and 2.9 and otherwise in
accordance with the terms hereof. No Interest Period may end after the Facility
Termination Date.

     2.11. Rates Applicable After Default. Notwithstanding anything to the
contrary contained in Section 2.8, 2.9 or 2.10, 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 8.2 requiring
unanimous consent of the Lenders to changes in interest rates), declare that no
Advance may be made as, converted into or continued as a Eurodollar Advance.
During the continuance of a Default the Required Lenders may, at their option,
by notice to the Borrower (which notice may be revoked at the option of the
Required Lenders notwithstanding any provision of Section 8.2 requiring
unanimous consent of the Lenders to changes in interest rates),

                                       24



declare that (i) each Eurodollar Advance shall bear interest for the remainder
of the applicable Interest Period at the rate otherwise applicable to such
Interest Period plus 2% per annum, (ii) each Floating Rate Advance shall bear
interest at a rate per annum equal to the Floating Rate in effect from time to
time plus 2% per annum and (iii) the LC Fee shall be increased by 2% per annum,
provided that, during the continuance of a Default under Section 7.6 or 7.7, the
interest rates set forth in clauses (i) and (ii) above and the increase in the
LC Fee set forth in clause (iii) above shall be applicable to all Credit
Extensions without any election or action on the part of the Agent or any
Lender.

     2.12. Method of Payment. All payments of the Obligations hereunder shall be
made, without setoff, deduction, or counterclaim, in immediately available funds
to the Agent at the 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 noon (local 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 and
except with respect to repayments of Swing Line Loans) 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 Bank One for each payment of principal,
interest, Reimbursement Obligations and fees as it becomes due hereunder. Each
reference to the Agent in this Section 2.12 shall also be deemed to refer, and
shall apply equally, to the LC Issuer, in the case of payments required to be
made by the Borrower to the LC Issuer pursuant to Section 2.19.6.

     2.13. Noteless Agreement; Evidence of Indebtedness. (i) Each Lender shall
maintain in accordance with its usual practice an account or accounts evidencing
the indebtedness of the 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.

     (iii) The entries maintained in the accounts maintained pursuant to
paragraphs (i) and (ii) above shall be prima facie evidence of the existence and
amounts of the Obligations therein recorded; provided, however, that the failure
of the 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, substantially in the form of Exhibits "E-1", "E-2", or "E-3" (each a
"Note"). In such event, the

                                       25



Borrower shall prepare, execute and deliver to such Lender such Note or Notes
payable to the order of such Lender. Thereafter, the Loans evidenced by each
such Note and interest thereon shall at all times (prior to any assignment
pursuant to Section 12.3) be represented by one or more Notes payable to the
order of the payee named therein, except to the extent that any such Lender
subsequently returns any such Note for cancellation and requests that such Loans
once again be evidenced as described in paragraphs (i) and (ii) above.

     2.14. 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.

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

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

                                       26



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

     2.18. Non-Receipt of Funds by the 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, 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 three days 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.

     2.19. Facility LCs.

          2.19.1. 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 of
     this Agreement and prior to the Facility Termination Date upon the request
     of the Borrower; provided that immediately after each such Facility LC is
     issued or Modified, (i) the aggregate amount of the outstanding LC
     Obligations shall not exceed $25,000,000 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, provided that Facility LC with a one (1) year expiration date may
     include renewals for additional one year periods, so long as it does not
     extend beyond (x).

          2.19.2. Participations. Upon the issuance or Modification by the LC
     Issuer of a Facility LC in accordance with this Section 2.19, the LC Issuer
     shall be deemed, without further action by any party hereto, to

                                       27



     have unconditionally and irrevocably sold to each Lender, and each Lender
     shall be deemed, without further action by any party hereto, to have
     unconditionally and irrevocably purchased from the LC Issuer, a
     participation in such Facility LC (and each Modification thereof) and the
     related LC Obligations in proportion to its Pro Rata Share.

          2.19.3. Notice. Subject to Section 2.19.1, the Borrower shall give the
     LC Issuer notice prior to 10:00 a.m. (Tulsa time) at least five Business
     Days prior to the proposed date of issuance or Modification of each
     Facility LC, specifying the beneficiary, the proposed date of issuance (or
     Modification) and the expiry date of such Facility LC, and describing the
     proposed terms of such Facility LC and the nature of the transactions
     proposed to be supported thereby. Upon receipt of such notice, the LC
     Issuer shall promptly notify the 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
     that such Facility LC shall be satisfactory to the LC Issuer and 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 reasonably requested (each, a "Facility LC
     Application"). In the event of any conflict between the terms of this
     Agreement and the terms of any Facility LC Application, the terms of this
     Agreement shall control.

          2.19.4. LC Fees. The 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 percentage set forth on the Pricing Schedule
     on the average daily undrawn stated amount under such standby Facility LC,
     such fee to be payable in arrears on each Payment Date, (such fee described
     as the "LC Fee". 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
     equal to 0.125%, and (y) documentary and processing charges in connection
     with the issuance or Modification of and draws under Facility LCs in
     accordance with the LC Issuer's standard schedule for such charges as in
     effect from time to time.

          2.19.5. Administration; Reimbursement by Lenders. Upon receipt from
     the beneficiary of any Facility LC of any demand for payment under such
     Facility LC, the LC Issuer shall notify the 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

                                       28



     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 2.19.6 below, plus (ii) interest on the
     foregoing amount to be reimbursed by such Lender, for each day from the
     date of the LC Issuer's demand for such reimbursement (or, if such demand
     is made after 11:00 a.m. (Tulsa time) on such date, from the next
     succeeding Business Day) to the date on which such Lender pays the amount
     to be reimbursed by it, at a rate of interest per annum equal to the
     Federal Funds Effective Rate for the first three days and, thereafter, at a
     rate of interest equal to the rate applicable to Floating Rate Advances.

          2.19.6. Reimbursement by Borrower. The Borrower shall be irrevocably
     and unconditionally obligated to reimburse the LC Issuer on or before the
     applicable LC Payment Date for any amounts to be paid by the LC Issuer upon
     any drawing under any Facility LC, without presentment, demand, protest or
     other formalities of any kind; provided that neither the 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 2% plus the rate applicable to Floating Rate Advances for such
     day if such day falls after such LC Payment Date. The LC Issuer will pay to
     each Lender ratably in accordance with its Pro Rata Share all amounts
     received by it from the Borrower for application in payment, in whole or in
     part, of the Reimbursement Obligation in respect of any Facility LC issued
     by the LC Issuer, but only to the extent such Lender has made payment to
     the LC Issuer in respect of such Facility LC pursuant to Section 2.19.5.
     Subject to the terms and conditions of this Agreement (including without
     limitation the submission of a Borrowing Notice in compliance with Section
     2.8 and the satisfaction of the applicable conditions precedent set forth
     in Article IV), the Borrower may request an Advance hereunder for the
     purpose of satisfying any Reimbursement Obligation.

          2.19.7. Obligations Absolute. The Borrower's obligations under this
     Section 2.19 shall be absolute and unconditional under any and all
     circumstances and irrespective of any setoff, counterclaim or defense to
     payment which the 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

                                       29



     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 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 2.19.7
     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 2.19.6.

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

          2.19.9. 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

                                       30



     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 2.19.9 is intended to limit the
     obligations of the Borrower under any other provision of this Agreement.

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

          2.19.11. Facility LC Collateral Account. The 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 8.1. 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 Bank One having a maturity
     not exceeding 30 days. Nothing in this Section 2.19.11 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 8.1.

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

     2.20. Swing Line Loans.

          2.20.1. Amount of Swing Line Loans. Upon the satisfaction of the
     conditions precedent set forth in Section 4.2 and, if such Swing Line Loan
     is to be made on the date

                                       31



     of the initial Advance hereunder, the satisfaction of the conditions
     precedent set forth in Section 4.1 as well, from and including the date of
     this Agreement and prior to the Facility Termination Date, the Swing Line
     Lender agrees, on the terms and conditions set forth in this Agreement, to
     make Swing Line Loans to the Borrower from time to time in an aggregate
     principal amount not to exceed the Swing Line Commitment, provided that the
     Aggregate Outstanding Credit Exposure shall not at any time exceed the
     Aggregate Commitment, and provided further that at no time shall the sum of
     (i) the Swing Line Lender's Pro Rata Share of the Swing Line Loans, plus
     (ii) the outstanding Revolving Loans made by the Swing Line Lender pursuant
     to Section 2.1, exceed the Swing Line Lender's Commitment at such time.
     Subject to the terms of this Agreement, the Borrower may borrow, repay and
     reborrow Swing Line Loans at any time prior to the Facility Termination
     Date.

          2.20.2. Borrowing Notice. The Borrower shall deliver to the Agent and
     the Swing Line Lender irrevocable notice (a "Swing Line Borrowing Notice")
     not later than noon (Tulsa time) on the Borrowing Date of each Swing Line
     Loan, specifying (i) the applicable Borrowing Date (which date shall be a
     Business Day), and (ii) the aggregate amount of the requested Swing Line
     Loan which shall be an amount not less than $100,000. The Swing Line Loans
     shall bear interest at the Floating Rate.

          2.20.3. Making of Swing Line Loans. Promptly after receipt of a Swing
     Line Borrowing Notice, the Agent shall notify each Lender by fax, or other
     similar form of transmission, of the requested Swing Line Loan. Not later
     than 2:00 p.m. (Tulsa time) on the applicable Borrowing Date, the Swing
     Line Lender shall make available the Swing Line Loan, in funds immediately
     available in Tulsa, to the Agent at its address specified pursuant to
     Article XIII. The Agent will promptly make the funds so received from the
     Swing Line Lender available to the Borrower on the Borrowing Date at the
     Agent's aforesaid address.

          2.20.4. Repayment of Swing Line Loans. Each Swing Line Loan shall be
     paid in full by the Borrower on or before the fifth (5th) Business Day
     after the Borrowing Date for such Swing Line Loan. In addition, the Swing
     Line Lender (i) may at any time in its sole discretion with respect to any
     outstanding Swing Line Loan, or (ii) shall on the fifth (5th) Business Day
     after the Borrowing Date of any Swing Line Loan, require each Lender
     (including the Swing Line Lender) to make a Revolving Loan in the amount of
     such Lender's Pro Rata Share of such Swing Line Loan (including, without
     limitation, any interest accrued and unpaid thereon), for the purpose of
     repaying such Swing Line Loan. Not later than noon (Tulsa time) on the date
     of any notice received pursuant to this Section 2.20.4, each Lender shall
     make available its required Revolving Loan, in funds immediately available
     in Tulsa to the Agent at its address specified pursuant to Article XIII.
     Revolving Loans made pursuant to this Section 2.20.4 shall initially be
     Floating Rate Loans and thereafter may be continued as Floating Rate Loans
     or converted into Eurodollar Loans in the manner provided in Section 2.10
     and subject to the other conditions and limitations set forth in this
     Article II. Unless a Lender shall have notified the Swing Line Lender,
     prior to its making any Swing Line Loan, that any applicable condition
     precedent set forth in Sections 4.1 or 4.2 had not then been satisfied,
     such

                                       32



     Lender's obligation to make Revolving Loans pursuant to this Section 2.20.4
     to repay Swing Line Loans shall be unconditional, continuing, irrevocable
     and absolute and shall not be affected by any circumstances, including,
     without limitation, (a) any set-off, counterclaim, recoupment, defense or
     other right which such Lender may have against the Agent, the Swing Line
     Lender or any other Person, (b) the occurrence or continuance of a Default
     or Unmatured Default, (c) any adverse change in the condition (financial or
     otherwise) of the Borrower, or (d) any other circumstances, happening or
     event whatsoever. In the event that any Lender fails to make payment to the
     Agent of any amount due under this Section 2.20.4, the Agent shall be
     entitled to receive, retain and apply against such obligation the principal
     and interest otherwise payable to such Lender hereunder until the Agent
     receives such payment from such Lender or such obligation is otherwise
     fully satisfied. In addition to the foregoing, if for any reason any Lender
     fails to make payment to the Agent of any amount due under this Section
     2.20.4, such Lender shall be deemed, at the option of the Agent, to have
     unconditionally and irrevocably purchased from the Swing Line Lender,
     without recourse or warranty, an undivided interest and participation in
     the applicable Swing Line Loan in the amount of such Revolving Loan, and
     such interest and participation may be recovered from such Lender together
     with interest thereon at the Federal Funds Effective Rate for each day
     during the period commencing on the date of demand and ending on the date
     such amount is received. On the Facility Termination Date, the Borrower
     shall repay in full the outstanding principal balance of the Swing Line
     Loans.

     2.21. Extension of Facility Termination Date. The Borrower may request an
extension of the Facility Termination Date by submitting a request for an
extension to the Agent (an "Extension Request") no more than 90 and no less than
30 days prior to the second (2nd) anniversary of the closing of this Agreement.
Promptly upon receipt of an Extension Request, the Agent shall notify each
Lender thereof and shall request each Lender to approve the Extension Request.
Each Lender approving the Extension Request shall deliver its written consent no
later than 15 days prior to such second (2nd) anniversary of the closing of this
Agreement. If the consent of each of the Lenders is received by the Agent, the
Facility Termination Date shall be extended by one year and the Agent shall
promptly notify the Borrower and each Lender of the new Facility Termination
Date.

     2.22. Replacement of Lender. If the Borrower is required pursuant to
Section 3.1, 3.2 or 3.5 to make any additional payment to any Lender or if any
Lender's obligation to make or continue, or to convert Floating Rate Advances
into, Eurodollar Advances shall be suspended pursuant to Section 3.3 (any Lender
so affected an "Affected Lender"), the Borrower may elect, if such amounts
continue to be charged or such suspension is still effective, to replace such
Affected Lender as a Lender party to this Agreement, provided that no Default or
Unmatured Default shall have occurred and be continuing at the time of such
replacement, and provided further that, concurrently with such replacement, (i)
another bank or other entity which is reasonably satisfactory to the 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
substantially in the form of Exhibit C and to become a Lender for all purposes
under this Agreement and to assume all obligations of the Affected Lender to be
terminated as of such date and to comply with the requirements of Section 12.3
applicable to assignments, and (ii) the

                                       33



Borrower shall pay to such Affected Lender in same day funds on the day of such
replacement (A) all interest, fees and other amounts then accrued but unpaid to
such Affected Lender by the Borrower hereunder to and including the date of
termination, including without limitation payments due to such Affected Lender
under Sections 3.1, 3.2 and 3.5, and (B) an amount, if any, equal to the payment
which would have been due to such Lender on the day of such replacement under
Section 3.4 had the Loans of such Affected Lender been prepaid on such date
rather than sold to the replacement Lender.

     2.23. Limitation of Interest. The Borrower, the Agent and the Lenders
intend to strictly comply with all applicable laws, including applicable usury
laws. Accordingly, the provisions of this Section 2.23 shall govern and control
over every other provision of this Agreement or any other Loan Document which
conflicts or is inconsistent with this Section 2.23, even if such provision
declares that it controls. As used in this Section 2.23, the term "interest"
includes the aggregate of all charges, fees, benefits or other compensation
which constitute interest under applicable law, provided that, to the maximum
extent permitted by applicable law, (a) any non-principal payment shall be
characterized as an expense or as compensation for something other than the use,
forbearance or detention of money and not as interest, and (b) all interest at
any time contracted for, reserved, charged or received shall be amortized,
prorated, allocated and spread, in equal parts during the full term of the
Obligations. In no event shall the Borrower or any other Person be obligated to
pay, or any Lender have any right or privilege to reserve, receive or retain,
(a) any interest in excess of the maximum amount of nonusurious interest
permitted under the laws of the State of Oklahoma or the applicable laws (if
any) of the United States or of any other applicable state, or (b) total
interest in excess of the amount which such Lender could lawfully have
contracted for, reserved, received, retained or charged had the interest been
calculated for the full term of the Obligations at the Highest Lawful Rate. On
each day, if any, that the interest rate (the "Stated Rate") called for under
this Agreement or any other Loan Document exceeds the Highest Lawful Rate, the
rate at which interest shall accrue shall automatically be fixed by operation of
this sentence at the Highest Lawful Rate for that day, and shall remain fixed at
the Highest Lawful Rate for each day thereafter until the total amount of
interest accrued equals the total amount of interest which would have accrued if
there were no such ceiling rate as is imposed by this sentence. Thereafter,
interest shall accrue at the Stated Rate unless and until the Stated Rate again
exceeds the Highest Lawful Rate when the provisions of the immediately preceding
sentence shall again automatically operate to limit the interest accrual rate.
The daily interest rates to be used in calculating interest at the Highest
Lawful Rate shall be determined by dividing the applicable Highest Lawful Rate
per annum by the number of days in the calendar year for which such calculation
is being made. None of the terms and provisions contained in this Agreement or
in any other Loan Document which directly or indirectly relate to interest shall
ever be construed without reference to this Section 2.21, or be construed to
create a contract to pay for the use, forbearance or detention of money at an
interest rate in excess of the Highest Lawful Rate. If the term of any
Obligation is shortened by reason of acceleration of maturity as a result of any
Default or by any other cause, or by reason of any required or permitted
prepayment, and if for that (or any other) reason any Lender at any time,
including but not limited to, the stated maturity, is owed or receives (and/or
has received) interest in excess of interest calculated at the Highest Lawful
Rate, then and in any such event all of any such excess interest shall be
canceled automatically as of the date of such acceleration, prepayment or other
event which produces the excess, and, if such excess interest has been paid

                                       34



to such Lender, it shall be credited pro tanto against the then-outstanding
principal balance of the Borrower's obligations to such Lender, effective as of
the date or dates when the event occurs which causes it to be excess interest,
until such excess is exhausted or all of such principal has been fully paid and
satisfied, whichever occurs first, and any remaining balance of such excess
shall be promptly refunded to its payor.

                                   ARTICLE III
                             YIELD PROTECTION; TAXES

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

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

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

     (iii) imposes any other condition the result of which is to increase the
cost to any Lender or any applicable Lending Installation or the LC Issuer of
making, funding or maintaining its Eurodollar Loans, or of issuing or
participating in Facility LCs, 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 Lender or applicable
Lending Installation or the LC Issuer, as the case may be, in connection with
such Eurodollar Loans, Commitment, Facility LCs or participations therein, then,
within 15 days of demand by such Lender or the LC Issuer, as the case may be,
the

                                       35



Borrower shall pay such Lender or the LC Issuer, as the case may be, such
additional amount or amounts as will compensate such Lender or the LC Issuer, as
the case may be, for such increased cost or reduction in amount received.

     3.2. Changes in Capital Adequacy Regulations. If a Lender or the LC Issuer
determines the amount of capital required or expected to be maintained by such
Lender or the LC Issuer, any Lending Installation of such Lender or the LC
Issuer, or any corporation controlling such Lender or the LC Issuer is increased
as a result of a Change, then, within 15 days of demand by such Lender or 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). "Change" means (i) any change after the date of this
Agreement in the Risk-Based Capital Guidelines or (ii) any adoption of or change
in any other law, governmental or quasi-governmental rule, regulation, policy,
guideline, interpretation, or directive (whether or not having the force of law)
after the date of this Agreement which affects the amount of capital required or
expected to be maintained by any Lender or the LC Issuer or any Lending
Installation or any corporation controlling any Lender or the LC Issuer.
"Risk-Based Capital Guidelines" means (i) the risk-based capital guidelines in
effect in the United States on the date of this Agreement, including transition
rules, and (ii) the corresponding capital regulations promulgated by regulatory
authorities outside the United States implementing the July 1988 report of the
Basle Committee on Banking Regulation and Supervisory Practices Entitled
"International Convergence of Capital Measurements and Capital Standards,"
including transition rules, and any amendments to such regulations adopted prior
to the date of this Agreement.

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

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

                                       36



     3.5. 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 3.5) such Lender, the LC Issuer 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 3.5) paid by the Agent, the LC Issuer or such Lender as a result of its
Commitment, any Loans made by it hereunder, or otherwise in connection with its
participation in this Agreement 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 3.6.

     (iv) Each Lender that is not incorporated under the laws of the United
States of America or a state thereof (each a "Non-U.S. Lender") agrees that it
will, not more than ten Business Days after the date of this Agreement, (i)
deliver to the Agent two duly completed copies of United States Internal Revenue
Service Form W-8BEN or W-8ECI, certifying in either case that such Lender is
entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes, and (ii) deliver to the
Agent a United States Internal Revenue Form W-8 or W-9, as the case may be, and
certify that it is entitled to an exemption from United States backup
withholding tax. Each Non-U.S. Lender further undertakes to deliver to each of
the 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

                                       37



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 3.5 with respect to Taxes imposed by the United States; provided
that, should a Non-U.S. Lender which is otherwise exempt from or subject to a
reduced rate of withholding tax become subject to Taxes because of its failure
to deliver a form required under clause (iv), above, the 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 3.5(vii) shall survive the payment of the Obligations and
termination of this Agreement.

     3.6. Lender Statements; Survival of Indemnity. To the extent reasonably
possible, each Lender shall designate an alternate Lending Installation with
respect to its Eurodollar Loans to reduce any liability of the Borrower to such
Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of
Eurodollar Advances under Section 3.3, so long as such designation is not, in
the 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 3.1, 3.2, 3.4 or 3.5. Such
written statement shall set forth in reasonable detail the calculations upon
which such Lender determined such amount and shall be final, conclusive and
binding on the 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

                                       38



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 3.1, 3.2, 3.4 and 3.5
shall survive payment of the Obligations and termination of this Agreement.

                                   ARTICLE IV
                              CONDITIONS PRECEDENT

     4.1. Initial Credit Extension. The Lenders shall not be required to make

which the Borrower and each Subsidiary is a party, upon which certificate the
Agent and the Lenders shall be entitled to rely until informed of any change in
writing by the Borrower.

     (iv) A certificate, signed by the chief financial officer of the Borrower,
stating that on the initial Credit Extension Date no Default or Unmatured

                                    ARTICLE V
                         REPRESENTATIONS AND WARRANTIES

                                       41



     The Borrower represents and warrants to the Lenders that:

     5.1. Existence and Standing. Each of the Borrower and its Subsidiaries is
an entity 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 as
set forth on Schedule "7" hereto, and has all requisite authority to conduct its
business in each jurisdiction in which its business is conducted; subject to the
Subsidiaries described on Schedule "8" hereto, which Borrower presently intends
to dissolve.

     5.2. 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.

     5.3. 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 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 a Subsidiary
pursuant to the terms of any such indenture, instrument or agreement. No order,
consent, adjudication, approval, license, authorization, or validation of, or
filing, recording or registration with, or exemption by, or other action in
respect of any governmental or public body or authority, or any subdivision
thereof, which has not been obtained by the 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.

     5.4. Financial Statements. The November 30, 2002 consolidated financial
statements of the Borrower and its Subsidiaries (but the June 30, 2002 audited
financial statements as to Hake Group) 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.

                                       42



     5.5. Material Adverse Change. Since November 30, 2002 there has been no
change in the business, Property, condition (financial or otherwise), prospects
or results of operations of the Hake Group which is not covered by the purchase
price holdback or of the Borrower and its Subsidiaries which could reasonably be
expected to have a Material Adverse Effect.

     5.6. 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 Agreement Accounting Principles and as to which no
Lien exists. The United States income tax returns of the Borrower and its
Subsidiaries have been audited by the Internal Revenue Service through the
fiscal year ended May 31, 1998 as to the Borrower, and January 31, 1997 as to
the Hake Group. 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.

     5.7. Litigation and Contingent Obligations. Except as set forth on Schedule
"9", 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
reasonably be expected to have a Material Adverse Effect or which seeks to
prevent, enjoin or delay the making of any Credit Extensions. Other than any
liability incident to any litigation, arbitration or proceeding which (i) could
not reasonably be expected to have a Material Adverse Effect or (ii) is set
forth on Schedule "9", the Borrower has no material contingent obligations not
provided for or disclosed in the financial statements referred to in Section
5.4.

     5.8. Subsidiaries. Schedule "10" contains an accurate list of all
Subsidiaries of the Borrower as of the date of this Agreement, setting forth
their respective jurisdictions of organization and the percentage of their
respective capital stock or other ownership interests owned by the Borrower or
other Subsidiaries. All of the issued and outstanding shares of capital stock or
other ownership interests of such Subsidiaries have been (to the extent such
concepts are relevant with respect to such ownership interests) duly authorized
and issued and are fully paid and non-assessable.

     5.9. ERISA. The Unfunded Liabilities of all Single Employer Plans do not in
the aggregate exceed $500,000. Neither the Borrower nor any other member of the
Controlled Group has incurred, or is reasonably expected to incur, any
withdrawal liability to Multiemployer Plans in excess of $500,000 in the
aggregate. 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

                                       43



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 not misleading.

     5.11. Regulation U. Margin stock (as defined in Regulation U) constitutes
less than 25% of the value of those assets of the 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 reasonably be expected to 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 reasonably be expected to have a Material Adverse Effect or (ii) any
agreement or instrument evidencing or governing 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 reasonably be expected to have a Material Adverse
Effect.

     5.14. Ownership of Properties. Except as set forth on Schedule "2", on the
date of this Agreement, the 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. ss. 2510.3-101 of
an employee benefit plan (as defined in Section 3(3) of ERISA) which is subject
to Title I of ERISA or any plan (within the meaning of Section 4975 of the
Code), and neither the execution of this Agreement nor the making of Credit
Extensions 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. Except as discussed on Schedule "11" hereto,
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 cannot
reasonably be expected to have a Material Adverse Effect. Neither the Borrower
nor any Subsidiary has received any notice to the effect that its operations are
not in material compliance with any of the requirements of applicable
Environmental Laws or are the subject of any federal or state investigation
evaluating whether any remedial action is needed to respond to a release of

                                       44



any toxic or hazardous waste or substance into the environment, which
non-compliance or remedial action could reasonably be expected to have a
Material Adverse Effect.

     5.17. Investment Company Act. Neither the 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. Subordinated Indebtedness. The Obligations constitute senior
indebtedness which is entitled to the benefits of the subordination provisions
of all outstanding Subordinated Indebtedness.

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

     5.21. 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.

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

                                       45



     (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.

     5.23. Payment and Performance Bonds. Attached hereto as Schedule "12" are
representative copies of payment and performance bonds utilized by the Borrower
and Subsidiaries. No such bonds (or any application or related documents)
currently, or in the future will, evidence any collateral or security of any
kind or nature in favor of the surety.

     5.24. Acquisition. All conditions precedent for the completion of the Hake
Acquisition have been satisfied.

                                   ARTICLE VI

substantially the same fields of enterprise as it is presently conducted and do
all things necessary to remain duly incorporated or organized, validly existing

and governmental charges and levies upon it or its income, profits or Property,
except those which are being contested in good faith by appropriate proceedings
and with respect to which adequate reserves have been set aside in accordance

permit the Agent and the Lenders, by their respective representatives and
agents, to inspect any of the Property, books and financial records of the
Borrower and each Subsidiary, to examine and make copies of the books of
accounts and other financial records of the Borrower and each Subsidiary, and to
discuss the affairs, finances and accounts of the Borrower and each Subsidiary
with, and to be advised as to the same by, their respective officers at such
reasonable times and intervals as the Agent or any Lender may designate.

     6.10. Dividends. The Borrower will not, nor will it permit any Subsidiary
to, declare or pay any dividends or make any distributions on its capital stock
(other than dividends payable in its own capital stock) or redeem, repurchase or
otherwise acquire or retire any of its capital stock at any time outstanding, in
excess of $1,000,000 during any given fiscal year, except that (i) the Borrower
may declare and pay dividends (not to exceed fifty percent (50%) of cumulative
net income) on its capital stock, and (ii) Subsidiaries may make unlimited
dividends to the Borrower, provided that no Default or Unmatured Default shall

merge into the Borrower or a Wholly-Owned Subsidiary.

     6.13. Sale of Assets. The Borrower will not, nor will it permit any
Subsidiary to, lease, sell or otherwise dispose of its Property to any other
Person, except:

     (i) Sales of inventory in the ordinary course of business.

Properties described on Schedule "15" hereto) that, together with all other
Property of the Borrower and its

                                       49



Subsidiaries previously leased, sold or disposed of (other than inventory in the
ordinary course of business) as permitted by this Section during the
twelve-month period ending with the month in which any such lease, sale or other
disposition occurs, do not constitute a Substantial Portion of the Property of
the Borrower and its Subsidiaries.

     6.14. Investments and Acquisitions. The Borrower will not, nor will it
permit any Subsidiary to, make or suffer to exist any Investments (excluding

described in Section 7.5, 7.6 or 7.7 occurs with respect to the Borrower or any
of its Subsidiaries, the obligations of the Lenders to make Loans hereunder and

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, less (y) the amount on deposit in the Facility LC
Collateral Account at such time which is free and clear of all rights and claims
of third 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 and
the obligation and power of the LC Issuer to issue Facility LCs, or declare the
Obligations to be due and payable, or both, whereupon the Obligations shall
become immediately due and payable, without presentment, demand, protest or
notice of any kind, all of which the 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

                                       56



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 at 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 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 while 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 7.5, 7.6
or 7.7 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.

     8.2. Amendments. Subject to the provisions of this Section 8.2, 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 postpone any
regularly scheduled payment of principal of any Loan or forgive all or any
portion of the principal amount thereof or any Reimbursement Obligation related
thereto, or reduce the rate or extend the time of payment of interest or fees
thereon or Reimbursement Obligations related thereto.

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

     (iii) Extend the Facility Termination Date, or reduce the amount or extend
the payment date for, the mandatory payments required under Section 2.2, or
increase the amount of

                                       57



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 8.2.

     (v) Release any Guarantor or, except as provided in the Collateral
Documents or as to the companies set forth on Schedule "8" or the Properties set

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

     8.3. Preservation of Rights. No delay or omission of the Lenders, the LC
Issuer or the 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 8.2, and then only to the extent in such writing
specifically set forth. All remedies contained in the Loan Documents or by law
afforded shall be cumulative and all shall be available to the Agent, the LC
Issuer and the Lenders until the Obligations have been paid in full.

and remain in full force and effect during the term of this Agreement.

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
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

                                       59



from information furnished to it by or on behalf of the Borrower, after Bank One
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 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 9.6 shall survive the termination of this Agreement.

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

     9.8. 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 Agreement Accounting Principles,
except that any calculation or determination which is to be made on a
consolidated basis shall be made for the Borrower and all its Subsidiaries,
including those Subsidiaries, if any, which are unconsolidated on the Borrower's
audited financial statements.

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

     9.10. Nonliability of Lenders. The relationship between the 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

                                       60



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.

     9.11.  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, (vii)
permitted by Section 12.4 and (viii) to rating agencies if requested or required
by such agencies in connection with a rating relating to the Advances hereunder.

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

     9.13. Disclosure. The Borrower and each Lender hereby (i) acknowledge and
agree that (a) one or more Affiliates of Bank One are or may become direct or
indirect equity investors in Borrower, and (b) Bank One and/or its Affiliates
from time to time may hold other investments in, make other loans to or have
other relationships with Borrower, and (ii) waive any liability of Bank One or
such Affiliate to the Borrower or any Lender, respectively, arising out of or
resulting from such investments, loans or relationships other than liabilities
arising out of the gross negligence or willful misconduct of Bank One or its
Affiliates.

                                    ARTICLE X
                                    THE AGENT

     10.1. Appointment; Nature of Relationship. Bank One, Oklahoma, NA 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 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 the term "secured party" as defined in the Oklahoma Uniform
Commercial Code and (iii) is acting as an independent contractor, the rights and
duties of which

                                       61



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.

     10.2. 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.

     10.3. 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.

     10.4. 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).

     10.5. 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 (or, if required in this Agreement, the 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. The
Agent shall be fully justified in failing or refusing to take any action
hereunder and under any other Loan Document unless it shall first be indemnified
to its satisfaction by the Lenders pro rata against any and all liability, cost
and expense that it may incur by reason of taking or continuing to take any such
action.

                                       62



     10.6. 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.

     10.7. 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.

     10.8. 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 3.5(vii) shall, notwithstanding the provisions of this
Section 10.8, be paid by the relevant Lender in accordance with the provisions
thereof. The obligations of the Lenders under this Section 10.8 shall survive
payment of the Obligations and termination of this Agreement.

     10.9. 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.

                                       63



     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 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 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 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

                                       64



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 "Prime Rate" as used in this Agreement shall mean
the prime rate, base rate or other analogous rate of the new Agent.

     10.13. Agent and Arranger Fees. The Borrower agrees to pay to the Agent and
the Arranger, for their respective accounts, the fees agreed to by the Borrower,
the Agent and the Arranger pursuant to that certain letter agreement dated
January 17, 2003, 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.

     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
Security Agreement(s) 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 Security Agreement(s).

     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 8.2, all of the Lenders) in
writing.

                                   ARTICLE XI
                            SETOFF; RATABLE PAYMENTS

     11.1. 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.

     11.2. Ratable Payments. If any Lender, whether by setoff or otherwise, has
payment made to it upon its Outstanding Credit Exposure (other than payments
received pursuant to Section 3.1, 3.2, 3.4 or 3.5) in a greater proportion than
that received by any other Lender, such Lender agrees, promptly upon demand, to
purchase a portion of the Aggregate Outstanding Credit Exposure held by the
other Lenders so that after such purchase each Lender will hold its Pro Rata
Share of the Aggregate Outstanding Credit Exposure. If any Lender, whether in

                                       65



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

     12.1. 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 permitted hereby, except
that (i) the Borrower shall not have the right to assign its rights or
obligations under the Loan Documents without the prior written consent of each
Lender, (ii) any assignment by any Lender must be made in compliance with
Section 12.3, and (iii) any transfer by Participation must be made in compliance
with Section 12.2. Any attempted assignment or transfer by any party not made in
compliance with this Section 12.1 shall be null and void, unless such attempted
assignment or transfer is treated as a participation in accordance with Section
12.3.2. The parties to this Agreement acknowledge that clause (ii) of this
Section 12.1 relates only to absolute assignments and this Section 12.1 does not
prohibit assignments creating security interests, including, without limitation,
(x) any pledge or assignment by any Lender of all or any portion of its rights
under this Agreement and any Note to a Federal Reserve Bank or (y) in the case
of a Lender which is a Fund, any pledge or assignment of all or any portion of
its rights under this Agreement and any Note to its trustee in support of its
obligations to its trustee; provided, however, that no such pledge or assignment
creating a security interest shall release the transferor Lender from its
obligations hereunder unless and until the parties thereto have complied with
the provisions of Section 12.3. The 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 12.3; provided, however, that the
Agent may in its discretion (but shall not be required to) follow instructions
from the Person which made any Loan or which holds any Note to direct payments
relating to such Loan or Note to another Person. Any assignee of the rights to
any Loan or any Note agrees by acceptance of such 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 or assignee of the rights to such Loan.

     12.2. Participations.

          12.2.1. Permitted Participants; Effect. Any Lender may, in the
     ordinary course of its business and in accordance with applicable law, at
     any time sell to one or more banks or other entities ("Participants")
     participating interests in any Outstanding Credit Exposure of such Lender,
     any Note held by such Lender, any Commitment of such

                                       66



     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.

          12.2.2. Voting Rights. Each Lender shall retain the sole right to
     approve, without the consent of any Participant, any amendment,
     modification or waiver of any provision of the Loan Documents other than
     any amendment, modification or waiver with respect to any Credit Extension
     or Commitment in which such Participant has an interest which would require
     consent of all of the Lenders pursuant to the terms of Section 8.2 or of
     any other Loan Document.

          12.2.3. Benefit of Certain Provisions. The Borrower agrees that each
     Participant shall be deemed to have the right of setoff provided in Section
     11.1 in respect of its participating interest in amounts owing under the
     Loan Documents to the same extent as if the amount of its participating
     interest were owing directly to it as a Lender under the Loan Documents,
     provided that each Lender shall retain the right of setoff provided in
     Section 11.1 with respect to the amount of participating interests sold to
     each Participant. The Lenders agree to share with each Participant, and
     each Participant, by exercising the right of setoff provided in Section
     11.1, agrees to share with each Lender, any amount received pursuant to the
     exercise of its right of setoff, such amounts to be shared in accordance
     with Section 11.2 as if each Participant were a Lender. The Borrower
     further agrees that each Participant shall be entitled to the benefits of
     Sections 3.1, 3.2, 3.4 and 3.5 to the same extent as if it were a Lender
     and had acquired its interest by assignment pursuant to Section 12.3,
     provided that (i) a Participant shall not be entitled to receive any
     greater payment under Section 3.1, 3.2 or 3.5 than the Lender who sold the
     participating interest to such Participant would have received had it
     retained such interest for its own account, unless the sale of such
     interest to such Participant is made with the prior written consent of the
     Borrower, and (ii) any Participant not incorporated under the laws of the
     United States of America or any State thereof agrees to comply with the
     provisions of Section 3.5 to the same extent as if it were a Lender.

     12.3. Assignments.

          12.3.1. Permitted Assignments. Any Lender may, in the ordinary course
     of its business and in accordance with applicable law, at any time assign
     to one or more banks or other entities ("Purchasers") all or any part of
     its rights and obligations under the Loan Documents. Such assignment shall
     be substantially in the form of Exhibit C or in such other form as may be
     agreed to by the parties thereto. The consent of the Borrower, the Agent
     and the LC Issuer shall be required prior to an assignment becoming
     effective with

                                       67



     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).

          12.3.2. Effect; Effective Date. Upon (i) delivery to the Agent of a
     notice of assignment, substantially in the form attached as Exhibit I to
     Exhibit C (a "Notice of Assignment"), together with any consents required
     by Section 12.3.1, and (ii) payment of a $3,500 fee to the Agent for
     processing such assignment, such assignment shall become effective on the
     effective date specified in such Notice of Assignment. The Notice of
     Assignment shall contain a representation by the Purchaser to the effect
     that none of the consideration used to make the purchase of the Commitment
     and Outstanding Credit Exposure under the applicable assignment agreement
     are "plan assets" as defined under ERISA and that the rights and interests
     of the Purchaser in and under the Loan Documents will not be "plan assets"
     under ERISA. On and after the effective date of such assignment, such
     Purchaser shall for all purposes be a Lender party to this Agreement and
     any other Loan Document executed by or on behalf of the Lenders and shall
     have all the rights and obligations of a Lender under the Loan Documents,
     to the same extent as if it were an original party hereto, and no further
     consent or action by the 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 12.3.2, 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.

          12.3.3. Register. The Agent, acting solely for this purpose as an
     agent of the Borrower, shall maintain at one of its offices in Tulsa,
     Oklahoma a copy of each Assignment and Assumption delivered to it and a
     register for the recordation of the names and addresses of the Lenders, and
     the Commitments of, and principal amounts of the Loans owing to, each
     Lender pursuant to the terms hereof from time to time (the "Register"). The
     entries in the Register shall be conclusive, and the Borrower, the Agent
     and the Lenders may treat each Person whose name is recorded in the
     Register pursuant to the terms hereof as a Lender hereunder for all
     purposes of this Agreement, notwithstanding notice to the contrary. The
     Register shall be available for inspection by the Borrower and any Lender,
     at any reasonable time and from time to time upon reasonable prior notice.

                                       68



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

     12.5. Tax Treatment. If any interest in any Loan Document is transferred to
any Transferee which is not incorporated under the laws of the United States or
any State thereof, the transferor Lender shall cause such Transferee,
concurrently with the effectiveness of such transfer, to comply with the
provisions of Section 3.5(iv).

                                  ARTICLE XIII

     13.2. 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

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

     The term "Financials" means the annual or quarterly consolidated financial
statements of the Borrower and its Subsidiaries.

     In the event the Applicable Margin is negative, it shall only be deducted
to the extent that the ABR is being calculated based upon the Prime Rate.

     For the six month period following the execution date of the Credit
Agreement, the Borrower's pricing shall be deemed to be no cheaper than the

                                    EXHIBIT A
                                 FORM OF OPINION

The Agent, the LC Issuer and the Lenders who are parties to the Credit Agreement
described below.

Gentlemen/Ladies:

     We are counsel for             (the "Borrower"), and have represented the
                       ------------
Borrower in connection with its execution and delivery of a Credit Agreement
dated as of March    , 2003 (the "Agreement") among the Borrower, the Lenders
                  ---
named therein, and Bank One, Oklahoma, NA, as Agent and as LC Issuer, and
providing for Credit Extensions in an aggregate principal amount not exceeding
$32,500,000 at any one time outstanding. All capitalized terms used in this
opinion and not otherwise defined herein shall have the meanings attributed to
them in the Agreement.

     We have examined the Borrower's **[describe constitutive documents of
Borrower and appropriate evidence of authority to enter into the transaction]**,
the Loan Documents and such other matters of fact and law which we deem
necessary in order to render this opinion. Based upon the foregoing, it is our
opinion that:

     l.Each of the Borrower and its Subsidiaries is a corporation,
partnership 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.

     2.The execution and delivery by the Borrower of the Loan Documents
**[to which it is a party]** and the performance by the Borrower of its
obligations thereunder have been duly authorized by proper corporate proceedings
on the part of the Borrower and will not:

          (a) require any consent of the Borrower's shareholders or members
     (other than any such consent as has already been given and remains in full
     force and effect);

          (b) 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 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

                                       78



     subject, or by which it, or its Property,is bound, or conflict with or
     constitute a default thereunder; or

          (c) result in, or require, the creation or imposition of any Lien in,
     of or on the Property of the Borrower or a Subsidiary pursuant to the terms
     of any indenture, instrument or agreement binding upon the Borrower or any
     of its Subsidiaries.

     3.The Loan Documents **[to which the Borrower is a party]** have
been duly executed and delivered by the Borrower and constitute legal, valid and
binding obligations of the Borrower enforceable against the Borrower in
accordance with their terms except to the extent the enforcement thereof may be
limited by bankruptcy, insolvency or similar laws affecting the enforcement of
creditors' rights generally and subject also to the availability of equitable
remedies if equitable remedies are sought. **[NOTE: If there are Loan Documents
executed by related entities other than the Borrower, separate provisions of the
opinion or additional opinions should cover those documents and their
enforceability against such parties.]**

     4.There is no litigation, arbitration, governmental investigation,
proceeding or inquiry pending or, to the best of our knowledge after due
inquiry, threatened against the Borrower or any of its Subsidiaries which, if
adversely determined, could reasonably be expected to have a Material Adverse
Effect.

     5.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 the 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.

     **[6. The Obligations constitute senior indebtedness which is entitled to
the benefits of the subordination provisions of all outstanding Subordinated
Indebtedness.]**

     **[7.The provisions of the Collateral Documents are sufficient to
create in favor of the Lenders and, to the extent they have entered into Rate
Management Transactions with the Borrower, the Lenders' Affiliates, a security
interest in all right, title and interest of the Borrower in those items and
types of collateral described in the Collateral Documents in which a security
interest may be created under Article 9 of the Uniform Commercial Code as in
effect on the date hereof in Oklahoma. Financing statements on Form UCC-1's have
been duly executed by the Borrower and have been duly filed in each filing
office indicated in Exhibit A hereto under the Uniform Commercial Code in effect
in each state in which said filing offices are located. The description of the
collateral set forth in said financing statements is sufficient to perfect a
security interest in the items and types of collateral described therein in
which a security interest may be perfected by the filing of a financing
statement under the Uniform Commercial Code as in effect in such states. Such
filings are sufficient to perfect the security interest created by the
Collateral Documents in all right, title and interest of the Borrower in those
items and types of

                                       79



collateral described in the Collateral Documents in which a security interest
may be perfected by the filing of a financing statement under the Uniform
Commercial Code in such states, except that we express no opinion as to personal
property affixed to real property in such manner as to become a fixture under
the laws of any state in which the collateral may be located and we call your
attention to the fact that the Lenders' (and, if applicable, their Affiliates')
security interest in certain of such collateral may not be perfected by filing
financing statements under the Uniform Commercial Code.]**

     This opinion may be relied upon by the Agent, the LC Issuer, the Lenders
and their participants, assignees and other transferees.

                                    Very truly yours,

                                                                  ---

HAKE GROUP, INC., a Delaware corporation; BOGAN, INC. (including Fiberspec, a

(collectively, the "Subsidiary Guarantors") in favor of the Agent, for the
benefit of the Lenders, under the Credit Agreement referred to below;

                                   WITNESSETH:

     WHEREAS, MATRIX SERVICE COMPANY, a Delaware corporation (the "Principal")
and BANK ONE, OKLAHOMA, NA, a national banking association having its principal
office in Tulsa, Oklahoma, as Agent (the "Agent"), and certain other Lenders
from time to time party thereto have entered into a certain Credit Agreement
dated as of even date herewith (as same may be amended or modified from time to
time, the "Credit Agreement"), providing, subject to the terms and conditions
thereof, for extensions of credit to be made by the Lenders to the Principal;

     WHEREAS, it is a condition precedent to the Agent and the Lenders the
Credit Agreement that each of the Subsidiary Guarantors execute and deliver this
Guaranty executing whereby each of the Subsidiary Guarantors shall guarantee the
payment when due, subject to Section 9 hereof, of all Guaranteed Obligations, as
defined below; and

     WHEREAS, in consideration of the financial and other support that the
Principal has provided, and such financial and other support as the Principal
may in the future provide, to the Subsidiary Guarantors, and in order to induce
the Lenders and the Agent to enter into the Credit Agreement, and the Lenders
and their Affiliates to enter into one or more Rate Management Transactions with
the Principal, and because each Subsidiary Guarantor has determined that
executing this Guaranty is in its interest and to its financial benefit, each of
the Subsidiary Guarantors is willing to guarantee the obligations of the
Principal under the Credit Agreement, any Note, any Rate Management Transaction,
and the other Loan Documents;

     NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

                                       100



     SECTION l.1. Selected Terms Used Herein.

     "Guaranteed Obligations" is defined in Section 3 below.

     "Rate Management Transaction" means any transaction (including an agreement
with respect thereto) now existing or hereafter entered into between the
Principal and any Lender or Affiliate thereof which is a rate swap, basis swap,
forward rate transaction, commodity swap, commodity option, equity or equity
index swap, equity or equity index option, bond option, interest rate option,
foreign exchange transaction, cap transaction, floor transaction, collar
transaction, forward transaction, currency swap transaction, cross-currency rate
swap transaction, currency option or any other similar transaction (including
any option with respect to any of these transactions) or any combination
thereof, whether linked to one or more interest rates, foreign currencies,
commodity prices, equity prices or other financial measures.

     "Rate Management Obligations" means any and all obligations of the
Principal, whether absolute or contingent and howsoever and whensoever created,
arising, evidenced or acquired (including all renewals, extensions and
modifications thereof and substitutions therefor), under (i) any and all Rate
Management Transactions, and (ii) any and all cancellations, buy backs,
reversals, terminations or assignments of any Rate Management Transactions.

     SECTION 1.2. Terms in Credit Agreement. Other capitalized terms used herein
but not defined herein shall have the meaning set
forth in the Credit Agreement.

     SECTION 2.1. Representations and Warranties. Each of the Subsidiary
Guarantors represents and warrants (which representations and warranties shall
be deemed to have been renewed upon each Borrowing Date under the Credit
Agreement) that:

          (a) It is a corporation, partnership 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.

          (b) It has the power and authority and legal right to execute and
deliver this Guaranty and to perform its obligations hereunder. The execution
and delivery by it of this Guaranty and the performance of its obligations
hereunder have been duly authorized by proper corporate proceedings, and this
Guaranty constitutes a legal, valid and binding obligation of such Subsidiary
Guarantor enforceable against it in accordance with its terms, except as
enforceability may be limited by bankruptcy, insolvency or similar laws
affecting the enforcement of creditors' rights generally.

          (c) Neither the execution and delivery by it of this Guaranty, nor the
consummation of the transactions herein contemplated, nor compliance with the
provisions hereof will violate (i) any law, rule, regulation, order, writ,
judgment, injunction, decree or award

                                       101



binding on it or any of its subsidiaries or (ii) its articles or certificate of
incorporation, partnership agreement, certificate of partnership, articles or
certificate of organization, by-laws, or operating or other management
agreement, as the case may be, or (iii) the provisions of any indenture,
instrument or agreement to which it 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 such Subsidiary Guarantor or
a subsidiary thereof 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 it or any of its
subsidiaries, is required to be obtained by it or any of its subsidiaries in
connection with the execution and delivery of this Guaranty or the performance
by it of its obligations hereunder or the legality, validity, binding effect or
enforceability of this Guaranty.

     SECTION 2.2. Covenants. Each of the Subsidiary Guarantors covenants that,
so long as any Lender has any Commitment outstanding under the Credit Agreement,
any Rate Management Transaction remains in effect or any of the Guaranteed
Obligations shall remain unpaid, that it will, and, if necessary, will enable
the Principal to, fully comply with those covenants and agreements set forth in
the Credit Agreement.

     SECTION 3. The Guaranty. Subject to Section 9 hereof, each of the
Subsidiary Guarantors hereby absolutely and unconditionally guarantees, as
primary obligor and not as surety, the full and punctual payment (whether at
stated maturity, upon acceleration or early termination or otherwise, and at all
times thereafter) and performance of the Obligations and the Rate Management
Obligations, including without limitation any such Obligations or Rate
Management Obligations incurred or accrued during the pendency of any
bankruptcy, insolvency, receivership or other similar proceeding, whether or not
allowed or allowable in such proceeding (collectively, subject to the provisions
of Section 9 hereof, being referred to collectively as the "Guaranteed
Obligations"). Upon failure by the Principal to pay punctually any such amount,
each of the Subsidiary Guarantors agrees that it shall forthwith on demand pay
to the Agent for the benefit of the Lenders and, if applicable, their
Affiliates, the amount not so paid at the place and in the manner specified in
the Credit Agreement, any Note, any Rate Management Transaction or the relevant
Loan Document, as the case may be. This Guaranty is a guaranty of payment and
not of collection. Each of the Subsidiary Guarantors waives any right to require
the Lender to sue the Principal, any other guarantor, or any other person
obligated for all or any part of the Guaranteed Obligations, or otherwise to
enforce its payment against any collateral securing all or any part of the
Guaranteed Obligations.

     SECTION 4. Guaranty Unconditional. Subject to Section 9 hereof, the
obligations of each of the Subsidiary Guarantors hereunder shall be
unconditional and absolute and, without limiting the generality of the
foregoing, shall not be released, discharged or otherwise affected by:

     (i) any extension, renewal, settlement, compromise, waiver or release in
     respect of any of the Guaranteed Obligations, by operation of law or
     otherwise, or any obligation of any

                                       102



     other guarantor of any of the Guaranteed Obligations, or any default,
     failure or delay, willful or otherwise, in the payment or performance of
     the Guaranteed Obligations;

     (ii) any modification or amendment of or supplement to the Credit
     Agreement, any Note, any Rate Management Transaction or any other Loan
     Document;

     (iii) any release, nonperfection or invalidity of any direct or indirect
     security for any obligation of the Principal under the Credit Agreement,
     any Note, the Security Agreement any Rate Management Transaction, any other
     Loan Document, or any obligations of any other guarantor of any of the
     Guaranteed Obligations, or any action or failure to act by the Agent, any
     Lender or any Affiliate of any Lender with respect to any collateral
     securing all or any part of the Guaranteed Obligations;

     (iv) any change in the corporate existence, structure or ownership of the
     Principal or any other guarantor of any of the Guaranteed Obligations, or
     any insolvency, bankruptcy, reorganization or other similar proceeding
     affecting the Principal, or any other guarantor of the Guaranteed
     Obligations, or its assets or any resulting release or discharge of any
     obligation of the Principal, or any other guarantor of any of the
     Guaranteed Obligations;

     (v) the existence of any claim, setoff or other rights which the Subsidiary
     Guarantors may have at any time against the Principal, any other guarantor
     of any of the Guaranteed Obligations, the Agent, any Lender or any other
     Person, whether in connection herewith or any unrelated transactions;

     (vi) any invalidity or unenforceability relating to or against the
     Principal, or any other guarantor of any of the Guaranteed Obligations, for
     any reason related to the Credit Agreement, any Rate Management
     Transaction, any other Loan Document, or any provision of applicable law or
     regulation purporting to prohibit the payment by the Principal, or any
     other guarantor of the Guaranteed Obligations, of the principal of or
     interest on any Note or any other amount payable by the Principal under the
     Credit Agreement, any Note, any Rate Management Transaction or any other
     Loan Document; or

     (vii) any other act or omission to act or delay of any kind by the
     Principal, any other guarantor of the Guaranteed Obligations, the Agent,
     any Lender or any other Person or any other circumstance whatsoever which
     might, but for the provisions of this paragraph, constitute a legal or
     equitable discharge of any Subsidiary Guarantor's obligations hereunder.

     SECTION 5. Discharge Only Upon Payment In Full: Reinstatement In Certain
Circumstances. Each of the Subsidiary Guarantor's obligations hereunder shall
remain in full force and effect until all Guaranteed Obligations shall have been
indefeasibly paid in full, the Commitments under the Credit Agreement shall have
terminated or expired and all Rate Management Transactions have terminated or
expired. If at any time any payment of the principal of or interest on any Note
or any other amount payable by the Principal or any other party under the Credit
Agreement, any Rate Management Transaction or any other Loan Document is
rescinded or

                                       103



must be otherwise restored or returned upon the insolvency, bankruptcy or
reorganization of the Principal or otherwise, each of the Subsidiary Guarantor's
obligations hereunder with respect to such payment shall be reinstated as though
such payment had been due but not made at such time.

     SECTION 6. Waivers. Each of the Subsidiary Guarantors irrevocably waives
acceptance hereof, presentment, demand, protest and, to the fullest extent
permitted by law, any notice not provided for herein, as well as any requirement
that at any time any action be taken by any Person against the Principal, any
other guarantor of any of the Guaranteed Obligations, or any other Person.

     SECTION 7. Subrogation. Each of the Subsidiary Guarantors hereby agrees not
to assert any right, claim or cause of action, including, without limitation, a
claim for subrogation, reimbursement, indemnification or otherwise, against the
Principal arising out of or by reason of this Guaranty or the obligations
hereunder, including, without limitation, the payment or securing or purchasing
of any of the Guaranteed Obligations by any of the Subsidiary Guarantors unless
and until the Guaranteed Obligations are indefeasibly paid in full, any
commitment to lend under the Credit Agreement and any other Loan Documents is
terminated and all Rate Management Transactions have terminated or expired.

     SECTION 8. Stay of Acceleration. If acceleration of the time for payment of
any of the Guaranteed Obligations is stayed upon the insolvency, bankruptcy or
reorganization of the Principal, all such amounts otherwise subject to
acceleration under the terms of the Credit Agreement, any Note, any Rate
Management Transaction or any other Loan Document shall nonetheless be payable
by each of the Subsidiary Guarantors hereunder forthwith on demand by the Agent
made at the request of the Required Lenders.

     SECTION 9. Limitation on Obligations. (a) The provisions of this Guaranty
are severable, and in any action or proceeding involving any state corporate
law, or any state, federal or foreign bankruptcy, insolvency, reorganization or
other law affecting the rights of creditors generally, if the obligations of any
Subsidiary Guarantor under this Guaranty would otherwise be held or determined
to be avoidable, invalid or unenforceable on account of the amount of such
Subsidiary Guarantor's liability under this Guaranty, then, notwithstanding any
other provision of this Guaranty to the contrary, the amount of such liability
shall, without any further action by the Subsidiary Guarantors, the Agent or any
Lender, be automatically limited and reduced to the highest amount that is valid
and enforceable as determined in such action or proceeding (such highest amount
determined hereunder being the relevant Subsidiary Guarantor's "Maximum
Liability"). This Section 9(a) with respect to the Maximum Liability of the
Subsidiary Guarantors is intended solely to preserve the rights of the Agent
hereunder to the maximum extent not subject to avoidance under applicable law,
and neither the Subsidiary Guarantor nor any other person or entity shall have
any right or claim under this Section 9(a) with respect to the Maximum
Liability, except to the extent necessary so that the obligations of the
Subsidiary Guarantor hereunder shall not be rendered voidable under applicable
law.

     (b) Each of the Subsidiary Guarantors agrees that the Guaranteed
Obligations may at any time and from time to time exceed the Maximum Liability
of each Subsidiary Guarantor, and may exceed the aggregate Maximum Liability of
all other Subsidiary Guarantors, without impairing

                                       104



this Guaranty or affecting the rights and remedies of the Agent hereunder.
Nothing in this Section 9(b) shall be construed to increase any Subsidiary
Guarantor's obligations hereunder beyond its Maximum Liability.

     (c) In the event any Subsidiary Guarantor (a "Paying Subsidiary Guarantor")
shall make any payment or payments under this Guaranty or shall suffer any loss
as a result of any realization upon any collateral granted by it to secure its
obligations under this Guaranty, each other Subsidiary Guarantor (each a
"Non-Paying Subsidiary Guarantor") shall contribute to such Paying Subsidiary
Guarantor an amount equal to such Non-Paying Subsidiary Guarantor's "Pro Rata
Share" of such payment or payments made, or losses suffered, by such Paying
Subsidiary Guarantor. For the purposes hereof, each Non-Paying Subsidiary
Guarantor's "Pro Rata Share" with respect to any such payment or loss by a
Paying Subsidiary Guarantor shall be determined as of the date on which such
payment or loss was made by reference to the ratio of (i) such Non-Paying
Subsidiary Guarantor's Maximum Liability as of such date (without giving effect
to any right to receive, or obligation to make, any contribution hereunder) or,
if such Non-Paying Subsidiary Guarantor's Maximum Liability has not been
determined, the aggregate amount of all monies received by such Non-Paying
Subsidiary Guarantor from the Principal after the date hereof (whether by loan,
capital infusion or by other means) to (ii) the aggregate Maximum Liability of
all Subsidiary Guarantors hereunder (including such Paying Subsidiary Guarantor)
as of such date (without giving effect to any right to receive, or obligation to
make, any contribution hereunder), or to the extent that a Maximum Liability has
not been determined for any Subsidiary Guarantors, the aggregate amount of all
monies received by such Subsidiary Guarantors from the Principal after the date
hereof (whether by loan, capital infusion or by other means). Nothing in this
Section 9 (c) shall affect any Subsidiary Guarantor's several liability for the
entire amount of the Guaranteed Obligations (up to such Subsidiary Guarantor's
Maximum Liability). Each of the Subsidiary Guarantors covenants and agrees that
its right to receive any contribution under this Guaranty from a Non-Paying
Subsidiary Guarantor shall be subordinate and junior in right of payment to all
the Guaranteed Obligations. The provisions of this Section 9(c) are for the
benefit of both the Agent and the Subsidiary Guarantors and may be enforced by
any one, or more, or all of them in accordance with the terms hereof.

     SECTION 10. Application of Payments. All payments received by the Agent
hereunder shall be applied by the Agent to payment of the Guaranteed Obligations
in the following order unless a court of competent jurisdiction shall otherwise
direct:

          (a) FIRST, to payment of all costs and expenses of the Agent incurred
     in connection with the collection and enforcement of the Guaranteed
     Obligations or of any security interest granted to the Agent in connection
     with any collateral securing the Guaranteed Obligations;

          (b) SECOND, to payment of that portion of the Guaranteed Obligations
     constituting accrued and unpaid interest and fees, pro rata among the
     Lenders and their Affiliates in accordance with the amount of such accrued
     and unpaid interest and fees owing to each of them;

                                       105



          (c) THIRD, to payment of the principal of the Guaranteed Obligations
     and the net early termination payments and any other Rate Management
     Obligations then due and unpaid from the Borrower to any of the Lenders or
     their Affiliates, pro rata among the Lenders and their Affiliates in
     accordance with the amount of such principal and such net early termination
     payments and other Rate Management Obligations then due and unpaid owing to
     each of them; and

          (d) FOURTH, to payment of any Guaranteed Obligations (other than those
     listed above) pro rata among those parties to whom such Guaranteed
     Obligations are due in accordance with the amounts owing to each of them.

     SECTION 11. Notices. All notices, requests and other communications to any
party hereunder shall be given or made by telecopier or other writing and
telecopied, or mailed or delivered to the intended recipient at its address or
telecopier number set forth on the signature pages hereof or such other address
or telecopy number as such party may hereafter specify for such purpose by
notice to the Agent in accordance with the provisions of Article XIII of the
Credit Agreement. Except as otherwise provided in this Guaranty, all such
communications shall be deemed to have been duly given when transmitted by
telecopier, or personally delivered or, in the case of a mailed notice sent by
certified mail return-receipt requested, on the date set forth on the receipt
(provided, that any refusal to accept any such notice shall be deemed to be
notice thereof as of the time of any such refusal), in each case given or
addressed as aforesaid.

     SECTION 12. No Waivers. No failure or delay by the Agent or any Lenders in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The rights and remedies provided in this Guaranty, the Credit Agreement, any
Note, any Rate Management Transaction and the other Loan Documents shall be
cumulative and not exclusive of any rights or remedies provided by law.

     SECTION 13. No Duty to Advise. Each of the Subsidiary Guarantors assumes
all responsibility for being and keeping itself informed of the Principal's
financial condition and assets, and of all other circumstances bearing upon the
risk of nonpayment of the Guaranteed Obligations and the nature, scope and
extent of the risks that each of the Subsidiary Guarantors assumes and incurs
under this Guaranty, and agrees that neither the Agent nor any Lender has any
duty to advise any of the Subsidiary Guarantors of information known to it
regarding those circumstances or risks.

     SECTION 14. Successors and Assigns. This Guaranty is for the benefit of the
Agent and the Lenders and their respective successors and permitted assigns and
in the event of an assignment of any amounts payable under the Credit Agreement,
any Note, any Rate Management Transaction, or the other Loan Documents, the
rights hereunder, to the extent applicable to the indebtedness so assigned,
shall be transferred with such indebtedness. This Guaranty shall be binding upon
each of the Subsidiary Guarantors and their respective successors and permitted
assigns.

                                       106



     SECTION 15. Changes in Writing. Neither this Guaranty nor any provision
hereof may be changed, waived, discharged or terminated orally, but only in
writing signed by each of the Subsidiary Guarantors and the Agent with the
consent of the Required Lenders.

     SECTION 16. Costs of Enforcement. Each of the Subsidiary Guarantors agrees
to pay all costs and expenses including, without limitation, all court costs and
attorneys' fees and expenses paid or incurred by the Agent or any Lender or any
Affiliate of any Lender in endeavoring to collect all or any part of the
Guaranteed Obligations from, or in prosecuting any action against, the
Principal, the Subsidiary Guarantors or any other guarantor of all or any part
of the Guaranteed Obligations.

     SECTION 17. GOVERNING LAW; SUBMISSION TO JURISDICTION; WAIVER OF JURY
TRIAL. THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAW OF THE STATE OF OKLAHOMA. EACH OF THE SUBSIDIARY GUARANTORS HEREBY SUBMITS
TO THE NONEXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE
NORTHERN DISTRICT OF OKLAHOMA AND OF ANY OKLAHOMA STATE COURT SITTING IN TULSA,
OKLAHOMA AND FOR PURPOSES OF ALL LEGAL PROCEEDINGS ARISING OUT OF OR RELATING TO
THIS GUARANTY (INCLUDING, WITHOUT LIMITATION, ANY OF THE OTHER LOAN DOCUMENTS)
OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH OF THE SUBSIDIARY GUARANTORS
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH
ANY OF THEM MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH
PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING
BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. EACH OF THE
SUBSIDIARY GUARANTORS, AND THE AGENT AND THE LENDERS ACCEPTING THIS GUARANTY,
HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL
PROCEEDING ARISING OUT OF OR RELATING TO THIS GUARANTY OR THE TRANSACTIONS
CONTEMPLATED HEREBY.

     SECTION 18. Taxes. etc. All payments required to be made by any of the
Subsidiary Guarantors hereunder shall be made without setoff or counterclaim and
free and clear of and without deduction or withholding for or on account of, any
present or future taxes, levies, imposts, duties or other charges of whatsoever
nature imposed by any government or any political or taxing authority thereof
(but excluding Excluded Taxes), provided, however, that if any of the Subsidiary
Guarantors is required by law to make such deduction or withholding, such
Subsidiary Guarantor shall forthwith (i) pay to the Agent or any Lender, as
applicable, such additional amount as results in the net amount received by the
Agent or any Lender, as applicable, equaling the full amount which would have
been received by the Agent or any Lender, as applicable, had no such deduction
or withholding been made, (ii) pay the full amount deducted to the relevant
authority in accordance with applicable law, and (iii) furnish to the Agent or
any Lender, as applicable, certified copies of official receipts evidencing
payment of such withholding taxes within 30 days after such payment is made.

                                       107



     SECTION 19. Setoff. Without limiting the rights of the Agent or the Lenders
under applicable law, if all or any part of the Guaranteed Obligations is then
due, whether pursuant to the occurrence of a Default or otherwise, then the
Guarantor authorizes the Agent and the Lenders to apply any sums standing to the
credit of the Guarantor with the Agent or any Lender or any Lending Installation
of the Agent or any Lender toward the payment of the Guaranteed Obligations.

                                       108



     IN WITNESS WHEREOF, each of the Subsidiary Guarantors has caused this

necessary to cause (i) the issuers of uncertificated securities which are

the holder of any Investment Property, to cause the Agent to have and retain
Control over such Securities or other Investment Property. Without limiting the
foregoing, the Borrower will, with respect to

     corporation, partnership, joint venture or limited liability company
     constituting Collateral to dissolve, liquidate, retire any of its capital
     stock or other Instruments or Securities evidencing ownership, reduce its
     capital or merge or consolidate with any other entity, or (ii) vote any of
     the Instruments, Securities or other Investment Property in favor of any of
     the foregoing.

          4.6.2. Issuance of Additional Securities. The Borrower will not permit
     or suffer the issuer of privately held corporate securities or other
     ownership interests in a corporation, partnership, joint venture or limited
     liability company constituting Collateral to issue any such securities or
     other ownership interests, any right to receive the same or any right to
     receive earnings, except to the Borrower.

     after the occurrence of a Default, without notice, to exercise all voting
     and corporate rights relating to the Collateral, including, without
     limitation, exchange, subscription or any other rights, privileges, or
     options pertaining to any corporate securities or other ownership interests
     or Investment Property in or of a corporation, partnership, joint venture
     or limited liability company constituting Collateral and the Stock Rights
     as if it were the absolute owner thereof.

any Pledged Deposit or fail to rollover said Pledged Deposit without the prior
written consent of the Agent.

     4.8. Deposit Accounts. The Borrower will (i) upon the Agent's request,
cause each bank or other financial institution in which it maintains (a) a
Deposit Account to enter into a control agreement with the Agent, in form and
substance satisfactory to the Agent in order to give the Agent Control of the
Deposit Account or (b) other deposits (general or special, time or demand,
provisional or final) to be notified of the security interest granted to the
Agent hereunder and cause each such bank or other financial institution to
acknowledge such notification in writing and (ii) upon the Agent's request
[after the occurrence and during the continuance of a Default], deliver to each
such bank or other financial institution a letter, in form and substance
acceptable to the Agent, transferring ownership of the Deposit Account to the

                                       133

     constituting such Security have been delivered to the Agent and such
     Security is properly defined as such under Article 8 of the Uniform
     Commercial Code of the applicable jurisdiction, whether as a result of
     actions by the issuer thereof or otherwise, or (ii) the Agent has entered
     into a control agreement with the issuer of such Security or with a
     securities intermediary relating to such Security and such Security is
     defined as such under Article 8 of the Uniform Commercial Code of the
     applicable jurisdiction, whether as a result of actions by the issuer
     thereof or otherwise.

     5.2. Acceleration and Remedies. Upon the acceleration of the obligations
under the Credit Agreement pursuant to Section 8.1 thereof, the Obligations and,
to the extent provided for under the Rate Management Transactions evidencing the
same, the Rate Management Obligations, shall immediately become due and payable

     commercially reasonable.

The Agent, on behalf of the secured parties, may comply with any applicable
state or federal law requirements in connection with a disposition of the

Default, the Borrower's rights under all licenses and all franchise agreements
shall inure to the Agent's benefit. In addition, the Borrower hereby irrevocably
agrees that the Agent may, following the occurrence and during the continuance

     No delay or omission of the Agent or any Lender to exercise any right or
remedy granted under this Security Agreement shall impair such right or remedy
or be construed to be a waiver of any Default or an acquiescence therein, and
any single or partial exercise of any such right or remedy shall not preclude
any other or further exercise thereof or the exercise of any other right or
remedy. No waiver, amendment or other variation of the terms, conditions or
provisions of this Security Agreement whatsoever shall be valid unless in
writing signed by the Agent with the concurrence or at the direction of the
Lenders required under Section 8.2 of the Credit Agreement and then only to the
extent in such writing specifically set forth. All rights and remedies contained

or Unmatured Default, the Borrower shall execute and deliver to the Agent

bank where the lockbox is located of the Lien of the Agent granted hereunder and
of irrevocable instructions to wire all amounts collected therein to a special
collateral account at the Agent.

     7.2. Collection of Receivables. The Agent may at any time after the
occurrence of a Default, by giving the Borrower written notice, elect to require
that the Receivables be paid directly to the Agent for the benefit of the
Lenders. In such event, the Borrower shall, and shall permit the Agent to,
promptly notify the account debtors or obligors under the Receivables of the
Lenders' interest therein and direct such account debtors or obligors to make
payment of all amounts then or thereafter due under the Receivables directly to
the Agent. Upon receipt of any such notice from the Agent, the Borrower shall
thereafter hold in trust for the Agent, on behalf of the Lenders, all amounts
and proceeds received by it with respect to the Receivables and Other Collateral
and immediately and at all times thereafter deliver to the Agent all such
amounts and proceeds in the same form as so received, whether by cash, check,
draft or otherwise, with any necessary endorsements. The Agent shall hold and
apply funds so received as provided by the terms of Sections 7.3 and 7.4.

     7.3. Special Collateral Account. The Agent may require all cash proceeds of
the Collateral to be deposited in a special non-interest bearing cash collateral
account with the Agent and held there as security for the Secured Obligations.
The Borrower shall have no control whatsoever over said cash collateral account.
If no Default or Unmatured Default has occurred or is continuing, the Agent
shall from time to time deposit the collected balances in said cash collateral
account into the Borrower's general operating account with the Agent. If any
Default or Unmatured Default has occurred and is continuing, the Agent may (and
shall, at the direction of the Required Lenders, from time to time, apply the
collected balances in said cash collateral account to the payment of the Secured
Obligations whether or not the Secured Obligations shall then be due.

     7.4. Application of Proceeds. The proceeds of the Collateral shall be
applied by the Agent to payment of the Secured Obligations in the following
order unless a court of competent jurisdiction shall otherwise direct:

          (a) FIRST, to payment of all costs and expenses of the Agent incurred
     in connection with the collection and enforcement of the Secured
     Obligations or of the security interest granted to the Agent pursuant to
     this Security Agreement;

          (b) SECOND, to payment of that portion of the Secured Obligations
     constituting accrued and unpaid interest and fees, pro rata among the
     Lenders and their

                                       137



     Affiliates in accordance with the amount of such accrued and unpaid
     interest and fees owing to each of them;

          (c) THIRD, to payment of the principal of the Secured Obligations and
     the net early termination payments and any other Rate Management
     Obligations then due and unpaid from the Borrower to any of the Lenders or
     their Affiliates, pro rata among the Lenders and their Affiliates in
     accordance with the amount of such principal and such net early termination
     payments and other Rate Management Obligations then due and unpaid owing to
     each of them;

          (d) FOURTH, to payment of any Secured Obligations (other than those
     listed above) pro rata among those parties to whom such Secured Obligations
     are due in accordance with the amounts owing to each of them; and

          (e) FIFTH, the balance, if any, after all of the Secured Obligations
     have been satisfied, shall be deposited by the Agent into the Borrower's
     general operating account with the Agent.

                                  ARTICLE VIII
                               GENERAL PROVISIONS

     8.1. Notice of Disposition of Collateral; Condition of Collateral. The
Borrower hereby waives notice of the time and place of any public sale or the
time after which any private sale or other disposition of all or any part of the
Collateral may be made. To the extent such notice may not be waived under
applicable law, any notice made shall be deemed reasonable if sent to the
Borrower, addressed as set forth in Article IX, at least ten days prior to (i)
the date of any such public sale or (ii) the time after which any such private
sale or other disposition may be made. Agent shall have no obligation to
clean-up or otherwise prepare the Collateral for sale.

     8.2. Compromises and Collection of Collateral. The Borrower and the Agent
recognize that setoffs, counterclaims, defenses and other claims may be asserted
by obligors with respect to certain of the Receivables, that certain of the
Receivables may be or become uncollectible in whole or in part and that the
expense and probability of success in litigating a disputed Receivable may
exceed the amount that reasonably may be expected to be recovered with respect
to a Receivable. In view of the foregoing, the Borrower agrees that the Agent
may at any time and from time to time, if a Default has occurred and is
continuing, compromise with the obligor on any Receivable, accept in full
payment of any Receivable such amount as the Agent in its sole discretion shall
determine or abandon any Receivable, and any such action by the Agent shall be
commercially reasonable so long as the Agent acts in good faith based on
information known to it at the time it takes any such action.

     8.3. Secured Party Performance of Debtor Obligations. Without having any
obligation to do so, the Agent may perform or pay any obligation which the
Borrower has agreed to perform or pay in this Security Agreement and the
Borrower shall reimburse the Agent for any

                                       138



amounts paid by the Agent pursuant to this Section 8.3. The Borrower's
obligation to reimburse the Agent pursuant to the preceding sentence shall be a
Secured Obligation payable on demand.

     8.4. Authorization for Secured Party to Take Certain Action. The Borrower
irrevocably authorizes the Agent at any time and from time to time in the sole
discretion of the Agent and appoints the Agent as its attorney in fact (i) to
execute on behalf of the Borrower as debtor and to file financing statements
necessary or desirable in the Agent's sole discretion to perfect and to maintain
the perfection and priority of the Agent's security interest in the Collateral,
(ii) to indorse and collect any cash proceeds of the Collateral, (iii) to file a
carbon, photographic or other reproduction of this Security Agreement or any
financing statement with respect to the Collateral as a financing statement and
to file any other financing statement or amendment of a financing statement
(which does not add new collateral or add a debtor) in such offices as the Agent
in its sole discretion deems necessary or desirable to perfect and to maintain
the perfection and priority of the Agent's security interest in the Collateral,
(iv) to contact and enter into one or more agreements with the issuers of
uncertificated securities which are Collateral and which are Securities or with
financial intermediaries holding other Investment Property as may be necessary
or advisable to give the Agent Control over such Securities or other Investment
Property, (v) subject to the terms of Section 4.1.5, to enforce payment of the
Receivables in the name of the Agent or the Borrower, (vi) to apply the proceeds
of any Collateral received by the Agent to the Secured Obligations as provided
in Article VII and (vii) to discharge past due taxes, assessments, charges, fees
or Liens on the Collateral (except for such Liens as are specifically permitted
hereunder), and the Borrower agrees to reimburse the Agent on demand for any
payment made or any expense incurred by the Agent in connection therewith,
provided that this authorization shall not relieve the Borrower of any of its
obligations under this Security Agreement or under the Credit Agreement.

     8.5. Specific Performance of Certain Covenants. The Borrower acknowledges
and agrees that a breach of any of the covenants contained in Sections 4.1.5,
4.1.6, 4.4, 5.3, or 8.7 or in Article VII will cause irreparable injury to the
Agent and the Lenders, that the Agent and Lenders have no adequate remedy at law
in respect of such breaches and therefore agrees, without limiting the right of
the Agent or the Lenders to seek and obtain specific performance of other
obligations of the Borrower contained in this Security Agreement, that the
covenants of the Borrower contained in the Sections referred to in this Section
8.5 shall be specifically enforceable against the Borrower.

     8.6. Use and Possession of Certain Premises. Upon the occurrence of a
Default, the Agent shall be entitled to occupy and use any premises owned or
leased by the Borrower where any of the Collateral or any records relating to
the Collateral are located until the Secured Obligations are paid or the
Collateral is removed therefrom, whichever first occurs, without any obligation
to pay the Borrower for such use and occupancy.

     8.7. Dispositions Not Authorized. The Borrower is not authorized to sell or
otherwise dispose of the Collateral except as set forth in Section 4.1.5 and
notwithstanding any course of dealing between the Borrower and the Agent or
other conduct of the Agent, no authorization to sell or otherwise dispose of the
Collateral (except as set forth in Section 4.1.5) shall be binding

                                       139



upon the Agent or the Lenders unless such authorization is in writing signed by
the Agent with the consent or at the direction of the Required Lenders.

     8.8. Benefit of Agreement. The terms and provisions of this Security
Agreement shall be binding upon and inure to the benefit of the Borrower, the
Agent and the Lenders and their respective successors and assigns (including all
persons who become bound as a debtor to this Security Agreement), except that
the Borrower shall not have the right to assign its rights or delegate its
obligations under this Security Agreement or any interest herein, without the
prior written consent of the Agent.

     8.9. Survival of Representations. All representations and warranties of the
Borrower contained in this Security Agreement shall survive the execution and
delivery of this Security Agreement.

     8.10. Taxes and Expenses. Any taxes (including income taxes) payable or
ruled payable by Federal or State authority in respect of this Security
Agreement shall be paid by the Borrower, together with interest and penalties,
if any. The Borrower shall reimburse the Agent for any and all out-of-pocket
expenses and internal charges (including reasonable attorneys', auditors' and
accountants' fees and reasonable time charges of attorneys, paralegals, auditors
and accountants who may be employees of the Agent) paid or incurred by the Agent
in connection with the preparation, execution, delivery, administration,
collection and enforcement of this Security Agreement and in the audit,
analysis, administration, collection, preservation or sale of the Collateral
(including the expenses and charges associated with any periodic or special
audit of the Collateral). Any and all costs and expenses incurred by the
Borrower in the performance of actions required pursuant to the terms hereof
shall be borne solely by the Borrower.

     8.11. Headings. The title of and section headings in this Security
Agreement are for convenience of reference only, and shall not govern the
interpretation of any of the terms and provisions of this Security Agreement.

     8.12. Termination. This Security Agreement shall continue in effect
(notwithstanding the fact that from time to time there may be no Secured
Obligations outstanding) until (i) the Credit Agreement has terminated pursuant
to its express terms and (ii) all of the Secured Obligations have been
indefeasibly paid and performed in full and no commitments of the Agent or the
Lenders which would give rise to any Secured Obligations are outstanding.

     8.13. Entire Agreement. This Security Agreement embodies the entire
agreement and understanding between the Borrower and the Agent relating to the
Collateral and supersedes all prior agreements and understandings between the
Borrower and the Agent relating to the Collateral.

     8.14. CHOICE OF LAW. THIS SECURITY AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS (AND NOT THE LAW OF CONFLICTS)
OF THE STATE OF OKLAHOMA, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO
NATIONAL BANKS.

                                       140



     8.15. Distribution of Reports. The Borrower authorizes the Agent, as the
Agent may elect in its sole discretion, to discuss with and furnish to its
affiliates and to the Lenders or to any other person or entity having an
interest in the Secured Obligations (whether as a guarantor, pledgor of
collateral, participant or otherwise) all financial statements, audit reports
and other information pertaining to the Borrower and its Subsidiaries whether
such information was provided by the Borrower or prepared or obtained by the
Agent. Neither the Agent nor any of its employees, officers, directors or agents
makes any representation or warranty regarding any audit reports or other
analyses of the Borrower's and its Subsidiaries' condition which the Agent may
in its sole discretion prepare and elect to distribute, nor shall the Agent or
any of its employees, officers, directors or agents be liable to any person or
entity receiving a copy of such reports or analyses for any inaccuracy or
omission contained in or relating thereto.

     8.16. Indemnity. The Borrower hereby agrees to indemnify the Agent and the
Lenders, and their respective successors, assigns, agents and employees, from
and against any and all liabilities, damages, penalties, suits, costs, and
expenses of any kind and nature (including, without limitation, all expenses of
litigation or preparation therefor whether or not the Agent or any Lender is a
party thereto) imposed on, incurred by or asserted against the Agent or the
Lenders, or their respective successors, assigns, agents and employees, in any

remedy. No waiver, amendment or other variation of the terms, conditions or
provisions of this Security Agreement whatsoever shall be valid unless in
writing signed by the Agent with the concurrence or at the direction of the
Lenders required under Section 8.2 of the Credit Agreement and then only to the

collateral account at the Agent.

     7.2. Collection of Receivables. The Agent may at any time after the
occurrence of a Default, by giving the Grantor written notice, elect to require

promptly notify the account debtors or obligors under the Receivables of the
Lenders' interest therein and direct such account debtors or obligors to make
payment of all amounts then or thereafter due under the Receivables directly to

thereafter hold in trust for the Agent, on behalf of the Lenders, all amounts
and proceeds received by it with respect to the Receivables and Other Collateral
and immediately and at all times thereafter deliver to the Agent all such
amounts and proceeds in the same form as so received, whether by cash, check,
draft or otherwise, with any necessary endorsements. The Agent shall hold and
apply funds so received as provided by the terms of Sections 7.3 and 7.4.

     7.3. Special Collateral Account. The Agent may require all cash proceeds of
the Collateral to be deposited in a special non-interest bearing cash collateral
account with the Agent and held there as security for the Secured Obligations.
The Grantor shall have no control whatsoever over said cash collateral account.
If no Default or Unmatured Default has occurred or is continuing, the Agent
shall from time to time deposit the collected balances in said cash collateral
account into the Grantor's general operating account with the Agent. If any
Default or Unmatured Default has occurred and is continuing, the Agent may (and

     in connection with the collection and enforcement of the Secured
     Obligations or of the security interest granted to the Agent pursuant to
     this Security Agreement;

                                       162



          (b) SECOND, to payment of that portion of the Secured Obligations
     constituting accrued and unpaid interest and fees, pro rata among the
     Lenders and their Affiliates in accordance with the amount of such accrued
     and unpaid interest and fees owing to each of them;

          (c) THIRD, to payment of the principal of the Secured Obligations and
     the net early termination payments and any other Rate Management
     Obligations then due and unpaid from the Grantor to any of the Lenders or
     their Affiliates, pro rata among the Lenders and their Affiliates in

     payments and other Rate Management Obligations then due and unpaid owing to
     each of them;

          (d) FOURTH, to payment of any Secured Obligations (other than those
     listed above) pro rata among those parties to whom such Secured Obligations
     are due in accordance with the amounts owing to each of them; and

          (e) FIFTH, the balance, if any, after all of the Secured Obligations
     have been satisfied, shall be deposited by the Agent into the Grantor's
     general operating account with the Agent.

                                  ARTICLE VIII
                               GENERAL PROVISIONS

     8.1. Notice of Disposition of Collateral; Condition of Collateral. The
Grantor hereby waives notice of the time and place of any public sale or the
time after which any private sale or other disposition of all or any part of the
Collateral may be made. To the extent such notice may not be waived under
applicable law, any notice made shall be deemed reasonable if sent to the
Grantor, addressed as set forth in Article IX, at least ten days prior to (i)
the date of any such public sale or (ii) the time after which any such private
sale or other disposition may be made. Agent shall have no obligation to
clean-up or otherwise prepare the Collateral for sale.

     8.2. Compromises and Collection of Collateral. The Grantor and the Agent
recognize that setoffs, counterclaims, defenses and other claims may be asserted
by obligors with respect to certain of the Receivables, that certain of the
Receivables may be or become uncollectible in whole or in part and that the
expense and probability of success in litigating a disputed Receivable may
exceed the amount that reasonably may be expected to be recovered with respect
to a Receivable. In view of the foregoing, the Grantor agrees that the Agent may
at any time and from time to time, if a Default has occurred and is continuing,
compromise with the obligor on any Receivable, accept in full payment of any
Receivable such amount as the Agent in its sole discretion shall determine or
abandon any Receivable, and any such action by the Agent shall be commercially
reasonable so long as the Agent acts in good faith based on information known to
it at the time it takes any such action.

                                       163



     8.3. Secured Party Performance of Debtor Obligations. Without having any
obligation to do so, the Agent may perform or pay any obligation which the
Grantor has agreed to perform or pay in this Security Agreement and the Grantor
shall reimburse the Agent for any amounts paid by the Agent pursuant to this
Section 8.3. The Grantor's obligation to reimburse the Agent pursuant to the
preceding sentence shall be a Secured Obligation payable on demand.

     8.4. Authorization for Secured Party to Take Certain Action. The Grantor
irrevocably authorizes the Agent at any time and from time to time in the sole
discretion of the Agent and appoints the Agent as its attorney in fact (i) to
execute on behalf of the Grantor as debtor and to file financing statements
necessary or desirable in the Agent's sole discretion to perfect and to maintain
the perfection and priority of the Agent's security interest in the Collateral,
(ii) to indorse and collect any cash proceeds of the Collateral, (iii) to file a
carbon, photographic or other reproduction of this Security Agreement or any
financing statement with respect to the Collateral as a financing statement and
to file any other financing statement or amendment of a financing statement
(which does not add new collateral or add a debtor) in such offices as the Agent
in its sole discretion deems necessary or desirable to perfect and to maintain
the perfection and priority of the Agent's security interest in the Collateral,
(iv) to contact and enter into one or more agreements with the issuers of
uncertificated securities which are Collateral and which are Securities or with
financial intermediaries holding other Investment Property as may be necessary
or advisable to give the Agent Control over such Securities or other Investment
Property, (v) subject to the terms of Section 4.1.5, to enforce payment of the
Receivables in the name of the Agent or the Grantor, (vi) to apply the proceeds
of any Collateral received by the Agent to the Secured Obligations as provided
in Article VII and (vii) to discharge past due taxes, assessments, charges, fees
or Liens on the Collateral (except for such Liens as are specifically permitted
hereunder), and the Grantor agrees to reimburse the Agent on demand for any
payment made or any expense incurred by the Agent in connection therewith,
provided that this authorization shall not relieve the Grantor of any of its
obligations under this Security Agreement or under the Credit Agreement.

     8.5. Specific Performance of Certain Covenants. The Grantor acknowledges
and agrees that a breach of any of the covenants contained in Sections 4.1.5,
4.1.6, 4.4, 5.3, or 8.7 or in Article VII will cause irreparable injury to the
Agent and the Lenders, that the Agent and Lenders have no adequate remedy at law
in respect of such breaches and therefore agrees, without limiting the right of
the Agent or the Lenders to seek and obtain specific performance of other
obligations of the Grantor contained in this Security Agreement, that the
covenants of the Grantor contained in the Sections referred to in this Section
8.5 shall be specifically enforceable against the Grantor.

     8.6. Use and Possession of Certain Premises. Upon the occurrence of a
Default, the Agent shall be entitled to occupy and use any premises owned or
leased by the Grantor where any of the Collateral or any records relating to the
Collateral are located until the Secured Obligations are paid or the Collateral
is removed therefrom, whichever first occurs, without any obligation to pay the
Grantor for such use and occupancy.

                                       164



     8.7. Dispositions Not Authorized. The Grantor is not authorized to sell or
otherwise dispose of the Collateral except as set forth in Section 4.1.5 and
notwithstanding any course of dealing between the Grantor and the Agent or other
conduct of the Agent, no authorization to sell or otherwise dispose of the
Collateral (except as set forth in Section 4.1.5) shall be binding upon the
Agent or the Lenders unless such authorization is in writing signed by the Agent
with the consent or at the direction of the Required Lenders.

     8.8. Benefit of Agreement. The terms and provisions of this Security
Agreement shall be binding upon and inure to the benefit of the Grantor, the
Agent and the Lenders and their respective successors and assigns (including all
persons who become bound as a debtor to this Security Agreement), except that
the Grantor shall not have the right to assign its rights or delegate its
obligations under this Security Agreement or any interest herein, without the
prior written consent of the Agent.

     8.9. Survival of Representations. All representations and warranties of the
Grantor contained in this Security Agreement shall survive the execution and
delivery of this Security Agreement.

                            ENVIRONMENTAL DISCLOSURES
                               (See Section 5.16)

     Matrix is a participant in certain environmental activities in various
stages involving assessment studies, cleanup operations and/or remedial
processes.

     In connection with the Company's sale of Brown and affiliated entities in
1999, an environmental assessment was conducted at Brown's Newnan, Georgia
facilities. The assessment turned up a number of deficiencies relating to storm
water permitting, air permitting and waste handling and disposal. An inspection
of the facilities also showed friable asbestos that needed to be removed. In
addition, Phase II soil testing indicated a number of volatile organic
compounds, semi-volatile organic compounds and metals above the state of Georgia
notification limits. Ground water testing also indicated a number of
contaminants above the State of Georgia notification limits.

     Appropriate State of Georgia agencies have been notified of the findings
and corrective and remedial actions have been completed, are currently underway,
or plans for such actions have been submitted to the State of Georgia for
approval on the remaining property. The current estimated total cost for cleanup
and remediation is $2,100,000, $100,000 of which remains accrued at May 31,
2002. Additional testing, however, could result in greater costs for cleanup and
remediation than is currently accrued.

     Matrix closed or sold the business operations of its San Luis Tank Piping
Construction Company, Inc. and West Coast Industrial Coatings, Inc.
subsidiaries, which are located in California. Although Matrix does not own the
land or building, it would be liable for any environmental exposure while
operating at the facility, a period from June 1, 1991 to the present. At the
present time, the environmental liability that could result from the testing is
unknown, however, Matrix has purchased a pollution liability insurance policy
with $5,000,000 of coverage for all operations.

                    HAKE GROUP HISTORICAL EBITDA CALCULATIONS

"AMRR" means, for the purposes of calculating Consolidated EBITDA, the average
monthly run rate for the Hake Group, equaling the six (6) month period ending
December 31, 2002 plus the two (2) month period ending February 28, 2003,
divided by eight (8).

EBITDA for the Hake Group shall be determined for the periods described below as
follows:

1. For the period ending May 31, 2003, AMRR times nine (9), plus the three (3)
month EBITDA calculation from February 28, 2003 to May 31, 2003.

2. For the period ending August 31, 2003, AMRR times six (6), plus the six (6)
month EBITDA calculation from February 23, 2003 to August 31, 2003.

3. For the period ending November 30, 2003, AMRR times three (3), plus the nine
(9) month EBITDA calculation from February 28, 2003 to November 30, 2003.

Commencing with the February 28, 2004 calculations, AMRR shall be disregarded.
