                  International Swap Dealers Association, Inc.

                                MASTER AGREEMENT

             dated as of _________________________________________

BANK ONE, OKLAHOMA, N.A. and MATRIX SERVICE COMPANY have entered and/or
anticipate entering into one or more transactions (each a "Transaction") that
are or will be governed by this Master Agreement, which includes the schedule
(the "Schedule"), and the documents and other confirming evidence (each a
"Confirmation") exchanged between the parties confirming those Transactions.

Accordingly, the parties agree as follows:

1.   Interpretation

(a)  Definitions. The terms defined in Section 12 and in the Schedule will have
the meanings therein specified for the purpose of this Master Agreement.

(b)  Inconsistency. In the event of any inconsistency between the provisions of
the Schedule and the other provisions of this Master Agreement, the Schedule
will prevail. In the event of any inconsistency between the provisions of any
Confirmation and this Master Agreement (including the Schedule), such
Confirmation will prevail for the purpose of the relevant Transaction.

(c)  Single Agreement. All Transactions are entered into in reliance on the fact
that this Master Agreement and all Confirmations form a single agreement between
the parties (collectively referred to as this "Agreement"), and the parties
would not otherwise enter into any Transactions.

2.   Obligations

(a)  General Conditions.

     (i) Each party will make each payment or delivery specified in each
     Confirmation to be made by it, subject to the other provisions of this
     Agreement.

     (ii) Payments under this Agreement will be made on the due date for value
     on that date in the place of the account specified in the relevant
     Confirmation or otherwise pursuant to

                                      -9-


     this Agreement, in freely transferable funds and in the manner customary
     for payments in the required currency. Where settlement is by delivery
     (that is, other than by payment), such delivery will be made for receipt on
     the due date in the manner customary for the relevant obligation unless
     otherwise specified in the relevant Confirmation or elsewhere in this
     Agreement.

     (iii)  Each obligation of each party under Section 2(a)(i) is subject to
     (1) the condition precedent that no Event of Default or Potential Event of
     Default with respect to the other party has occurred and is continuing, (2)
     the condition precedent that no Early Termination Date in respect of the
     relevant Transaction has occurred or been effectively designated and (3)
     each other applicable condition precedent specified in this Agreement.

(b)  Change of Account. Either party may change its account for receiving a
payment or delivery by giving notice to the other party at least five Local
Business Days prior to the scheduled date for the payment or delivery to which
such change applies unless such other party gives timely notice of a reasonable
objection to such change.

(c)  Netting.  If on any date amounts would otherwise be payable:

     (i)  in the same currency; and

     (ii) in respect of the same Transaction,

by each party to the other, then, on such date, each party's obligation to make
payment of any such amount will be automatically satisfied and discharged and,
if the aggregate amount that would otherwise have been payable by one party
exceeds the aggregate amount that would otherwise have been payable by the other
party, replaced by an obligation upon the party by whom the larger aggregate
amount would have been payable to pay to the other party the excess of the
larger aggregate amount over the smaller aggregate amount.

The parties may elect in respect of two or more Transactions that a net amount
will be determined in respect of all amounts payable on the same date in the
same currency in respect of such Transactions, regardless of whether such
amounts are payable in respect of the same Transaction. The election may be made
in the Schedule or a Confirmation by specifying that subparagraph (ii) above
will not apply to the Transactions identified as being subject to the election,
together with the starting date (in which case subparagraph (ii) above will not,
or will cease to, apply to such Transactions from such date). This election may
be made separately for different groups of Transactions and will apply
separately to each pairing of branches or offices through which the parties make
and receive payments or deliveries.

(d)  Default Interest; Other Amounts. Prior to the occurrence or effective
designation of an Early Termination Date in respect of the relevant Transaction,
a party that defaults in the performance of any payment obligation will, to the
extent permitted by law and subject to Section

                                      -10-


6(c), be required to pay interest (before as well as after judgment) on the
overdue amount to the other party on demand in the same currency as such overdue
amount~ for the period from (and including) the original due date for payment to
(but excluding) the date of actual payment, at the Default Rate. Such interest
will be calculated on the basis of daily compounding and the actual number of
days elapsed. If, prior to the occurrence or effective designation of an Early
Termination Date in respect of the relevant Transaction, a party defaults in the
performance of any obligation required to be settled by delivery, it will
compensate the other party on demand if-and to the extent provided for in the
relevant Confirmation or elsewhere in this Agreement-

3.   Representations

Each party represents to the other party (which representations will be deemed
to be repeated by each party on each date on which a Transaction is entered
into) that-

(a)  Basic Representations.

     (i) Status. It is duly organized and validly existing under the laws of the
     jurisdiction of its organization or incorporation and, if relevant under

     documentation relating to this Agreement to which it is a party, to deliver

     under this Agreement and any obligations it has under any Credit Support
     Document to which it is a party and has taken all necessary action to
     authorize such execution, delivery and performance;

     (iii)  No Violation or Conflict. Such execution, delivery and performance
     do not violate or conflict with any law applicable to it~ any provision of
     its constitutional documents, any order or judgment of any court or other
     agency of government applicable to it or any of its assets or any
     contractual restriction binding on or affecting it or any of its assets;

     (iv) Consents. All governmental and other consents that are required to

     force and effect and all conditions of any such consents have been complied
     with; and

     (v) Obligations Binding. Its obligations under this Agreement and any
     Credit Support Document to which it is a party constitute its legal, valid
     and binding obligations, enforceable in accordance with their respective
     terms (subject to applicable bankruptcy, reorganization, insolvency,
     moratorium or similar laws affecting creditors' rights generally and
     subject, as to enforceability, to equitable principles of general
     application (regardless of whether enforcement is sought in a proceeding in
     equity or at law)).

                                      -11-


(b)  Absence of Certain Events. No Event of Default or Potential Event of

(c)  Absence of Litigation. There is not pending or, to its knowledge,
     threatened against it or any of its Affiliates any action, suit or
     proceeding at law or in equity or before any court, tribunal, governmental
     body, agency or official or any arbitrator that is likely to affect the
     legality, validity or enforceability against it of this Agreement or any
     Credit Support Document to which it is a party or its ability to perform
     its obligations under this Agreement or such Credit Support Document.

(d)  Accuracy of Specified Information. All applicable information that is
     furnished in writing by or on behalf of it to the other party and is
     identified for the purpose of this Section 3(d) in the Schedule is, as of
     the date of the information, true, accurate and complete in every material
     respect.

Each party agrees with the other that, so long as either party has or may have
any obligation under this Agreement or under any Credit Support Document to
which it is a party:-

(a)  Furnish Specified Information. It will deliver to the other party any

     reasonable efforts to obtain any that may become necessary in the future.

(c)  Comply with Laws. It will comply in all material respects with all
     applicable laws and orders to which it may be subject if failure so to
     comply would materially impair its ability to perform its obligations under

5.   Events of Default and Termination Events

(a)  Events of Default. The occurrence at any time with respect to a party or,
     if applicable, any Credit Support Provider of such party or any Specified
     Entity of such party of any of the following events constitutes an event of
     default (an "Event of Default") with respect to such party:-

     (i) Failure to Pay or Deliver. Failure by the party to make, when due, any
     payment under this Agreement or delivery under Section 2(a)(i) or 2(d)
     required to be made by it if such failure is not remedied on or before the
     third Local Business Day after notice of such failure is given to the
     party;

                                      -12-


     (ii) Breach of Agreement. Failure by the party to comply with or perform
     any agreement or obligation (other than an obligation to make any payment
     under this Agreement or delivery under Section 2(a)(i) or 2(d) or to give
     notice of a Termination Event) to be complied with or performed by the
     party in accordance with this Agreement if such failure is not remedied on
     or before the thirtieth day after notice of such failure is given to the
     party;

     (iii)  Credit Support Default.

          (1) Failure by the party or any Credit Support Provider of such party
     to comply with or perform any agreement or obligation to be complied with
     or performed by it in accordance with any Credit Support Document if such
     failure is continuing after any applicable grace period has elapsed;

          (2) the expiration or termination of such Credit Support Document or
     the failing or ceasing of such Credit Support Document to be in full force
     and effect for the purpose of this Agreement (in either case other than in
     accordance with its terms) prior to the satisfaction of all obligations of
     such party under each Transaction to which such Credit Support Document
     relates without the written consent of the other party; or

          (3) the party or such Credit Support Provider disaffirms, disclaims,
     repudiates or rejects, in whole or in part, or challenges the validity of,
     such Credit Support Document;

     (iv) Misrepresentation. A representation made or repeated or deemed to have
     been made or repeated by the party or any Credit Support Provider of such
     party in this Agreement or any Credit Support Document proves to have been
     incorrect or misleading in any material respect when made or repeated or
     deemed to have been made or repeated;

     (v) Default under Specified Transaction. The party, any Credit Support
     Provider of such party or any applicable Specified Entity of such party (1)

     applicable notice requirement or grace period, there occurs a liquidation
     of, an acceleration of obligations under, or an early termination of, that
     Specified Transaction, (2) defaults, after giving effect to any applicable
     notice requirement or grace period, in making any payment or delivery due
     on the last payment, delivery or exchange date of, or any payment on early
     termination of, a Specified Transaction (or such default continues for at
     least three Local Business Days if there is no applicable notice
     requirement or grace period) or (3) disaffirms, disclaims, repudiates or
     rejects, in whole or in part, a Specified Transaction (or such action is
     taken by any person or entity appointed or empowered to operate it or act
     on its behalf);

     (vi) Cross Default. If "Cross Default" is specified in the Schedule as
     applying to the party, the occurrence or existence of (1) a default, event
     of default or other similar condition

                                      -13-


     or event (however described) in respect of such. party, any Credit Support
     Provider of such party or any applicable Specified Entity of such party
     under one or more agreements or instruments relating to Specified
     Indebtedness of any of them (individually or collectively) in an aggregate
     amount of not less than the applicable Threshold Amount (as specified in
     the Schedule) which has resulted in such Specified Indebtedness becoming,
     or becoming capable at such time of being declared, due and payable under
     such agreements or instruments, before it would otherwise have been due and
     payable or (2) a default by such party, such Credit Support Provider or
     such Specified Entity (individually or collectively) in making one or more
     payments on the due date thereof in an aggregate amount of not less than

     giving effect to any applicable notice requirement or grace period);

     (vii)  Bankruptcy. The party, any Credit Support Provider of such party or
     any applicable Specified Entity of such party:

            (1) is dissolved (other than pursuant to a consolidation,
            amalgamation or merger); (2) becomes insolvent or is unable to pay
            its debts or fails or admits in writing its inability generally to
            pay its debts as they become due; (3) makes a general assignment,
            arrangement or composition with or for the benefit of its creditors;
            (4) institutes or has instituted against it a proceeding seeking a
            judgment of insolvency or bankruptcy or any other relief under any
            bankruptcy or insolvency law or other similar law affecting
            creditors* rights, or a petition is presented for its winding-up or
            liquidation, and, in the case of any such proceeding or petition
            instituted or presented against it, such proceeding or petition (A)
            results in a judgment of insolvency or bankruptcy or the entry of an
            order for relief or the making of an order for its winding-up or
            liquidation or (B) is not dismissed, discharged, stayed or

            consolidation, amalgamation or merger); (6) seeks or becomes subject
            to the appointment of an administrator, provisional liquidator,
            conservator, receiver, trustee, custodian or other similar official

            party take possession of all or substantially all its assets or has
            a distress, execution, attachment, sequestration or other legal
            process levied, enforced or sued on or against all or substantially
            all its assets and such secured party maintains possession, or any
            such process is not dismissed, discharged, stayed or restrained, in
            each case within 30 days thereafter; (8) causes or is subject to any
            event with respect to it which, under the applicable laws of any
            jurisdiction, has an analogous effect to any of the events specified
            in clauses (1) to (7) (inclusive); or (9) takes any action in
            furtherance of, or indicating its consent to, approval of, or
            acquiescence in, any of the foregoing acts; or

     (viii)  Merger Without Assumption. The party or any Credit Support Provider
     of such party consolidates or amalgamates with, or merges with or into, or
     transfers all or substantially all

                                      -14-


     its assets to, another entity and, at the time of such consolidation,
     amalgamation, merger or transfer

        (1) the resulting, surviving or transferee entity fails to assume all
        the obligations of such party or such Credit Support Provider under this
        Agreement or any Credit Support Document to which it or its predecessor
        was a party by operation of law or pursuant to an agreement reasonably
        satisfactory to the other party to this Agreement; or

        (2) the benefits of any Credit Support Document fail to extend (without
        the consent of the other party) to the performance by such resulting,
        surviving or transferee entity of its obligations under this Agreement.

(b)  Termination Events. The occurrence at any time with respect to a party or,
     if applicable, any Credit Support Provider of such party or any Specified
     Entity of such party of any event specified below constitutes an Illegality
     if the event is specified in (i) below, and, if specified to be applicable,
     a Credit Event Upon Merger if the event is specified pursuant to (ii) below
     or an Additional Termination Event if the event is specified pursuant to
     (iii) below:

     (i) Illegality. Due to the adoption of, or any change in, any applicable
     law after the date on which a Transaction is entered into, or due to the
     promulgation of, or any change in, the interpretation by any court,
     tribunal or regulatory authority with competent jurisdiction of any
     applicable law after such date, it becomes unlawful (other than as a result
     of a breach by the party of Section 4(b)) for such party (which will be the
     Affected Party):-

          (1) to perform any absolute or contingent obligation to make a payment
          or delivery or to receive a payment or delivery in respect of such
          Transaction or to comply with any other material provision of this
          Agreement relating to such Transaction; or

          (2) to perform, or for any Credit Support Provider of such party to
          perform, any contingent or other obligation which the party (or such
          Credit Support Provider) has under any Credit Support Document
          relating to such Transaction;

     (ii) Credit Event Upon Merger. If "Credit Event Upon Merger" is specified
     in the Schedule as applying to the party, such party ("X"), any Credit
     Support Provider of X or any applicable Specified Entity of X consolidates
     or amalgamates with, or merges with or into, or transfers all or
     substantially all its assets to, another entity and such action does not
     constitute an event described in Section 5(a)(viii) but the
     creditworthiness of the resulting, surviving or transferee entity is
     materially weaker than that of X, such Credit Support Provider or such
     Specified Entity, as the case may be, immediately prior to such action
     (and, in such event, X or its successor or transferee, as appropriate, will
     be the Affected Party); or

                                      -15-


     (iii)  Additional Termination Event. If any "Additional Termination Event"
     is specified in the Schedule or any Confirmation as applying, the
     occurrence of such event (and, in such event, the Affected Party or
     Affected Parties shall be as specified for such Additional Termination
     Event in the Schedule or such Confirmation).

(c)  Event of Default and Illegality. If an event or circumstance which would
     otherwise constitute or give rise to all Event of Default also constitutes
     an Illegality, it will be treated as an Illegality and will not constitute
     an Event of Default.

6.   Early Termination

(a)  Right to Terminate Following Event of Default. If at any time an Event of
     Default with respect to a party (the "Defaulting Party") has occurred and
     is then continuing, the other party (the "Non-defaulting Party") may, by
     not more than 20 days notice to the Defaulting Party specifying the
     relevant Event of Default, designate a day not earlier than the day such
     notice is effective as an Early Termination Date in respect of all
     outstanding Transactions. If, however, "Automatic Early Termination" is
     specified in the Schedule as applying to a party, then an Early Termination
     Date in respect of all outstanding Transactions will occur immediately upon
     the occurrence with respect to such party of an Event of Default specified
     in Section 5(a)(vii)(1), (3), (5), (6) or, to the extent analogous thereto,
     (8), and as of the time immediately preceding the institution of the
     relevant proceeding or the presentation of the relevant petition upon the
     occurrence with respect to such party of an Event of Default specified in
     Section 5(a)(vii)(4) or, to the extent analogous thereto, (8).

(b)  Right to Terminate Following Termination Event.

     (i) Notice. If a Termination Event occurs, an Affected Party will, promptly
     upon becoming aware of it, notify the other party, specifying the nature of
     that Termination Event and each Affected Transaction and will also give
     such other information about that Termination Event as the other party may
     reasonably require-

     (ii) Two Affected Parties. If an Illegality under Section 5(b)(i)(1) occurs
     and there are two Affected Parties, each party will use all reasonable
     efforts to reach agreement within 30 days after notice thereof is given
     under Section 6(b)(i) on action to avoid that Termination Event.

     (iii)  Right to Terminate. If:

          (1) an agreement under Section 6(b)(ii) has not been effected with
          respect to all Affected Transactions within 30 days after an Affected
          Party gives notice under Section 6(b)(i); or

          (2) an Illegality other than that referred to in Section 6(b)(ii), a
          Credit Event Upon Merger or an Additional Termination Event occurs,

                                      -16-


either party in the case of an Illegality, any Affected Party in the case of an
Additional Termination Event if there is more than one Affected Party, or the
party which is not the Affected Party in the case of a Credit Event Upon Merger
or an Additional Termination Event if there is only one Affected Party may, by
not more than 20 days notice to the other party and provided that the relevant
Termination Event is then continuing, designate a day not earlier than the day
such notice is effective as an Early Termination Date in respect of all Affected
Transactions.

(c)  Effect of Designation.

     (i) If notice designating an Early Termination Date is given under Section
     6(a) or (b), the Early Termination Date will occur on the date so
     designated, whether or not the relevant Event of Default or Termination
     Event is then continuing.

     (ii) Upon the occurrence or effective designation of an Early Termination
     Date, no further payments or deliveries under Section 2(a)(i) or 2(d) in
     respect of the Terminated Transactions will be required to be made, but
     without prejudice to the other provisions of this Agreement. The amount, if
     any, payable in respect of an Early Termination Date shall be determined
     pursuant to Section 6(e).

(d)  Calculations.

     (i) Statement. On or as soon as reasonably practicable following the
     occurrence of an Early Termination Date, each party will make the
     calculations on its part, if any, contemplated by Section 6(e) and will
     provide to the other party a statement (1) showing, in reasonable detail,
     such calculations (including all relevant quotations and specifying any
     amount payable under Section 6(e)) and (2) giving details of the relevant
     account to which any amount payable to it is to be paid. In the absence of
     written confirmation from the source of a quotation obtained in determining
     a Market Quotation, the records of the party obtaining such quotation will
     be conclusive evidence of the existence and accuracy of such quotation.

     (ii) Payment Date. An amount calculated as being due in respect of any
     Early Termination Date under Section 6(e) will be payable on the day that
     notice of the amount payable is effective (in the case of an Early
     Termination Date which is designated or occurs as a result of an Event of
     Default) and on the day which is two Local Business Days after the day on
     which notice of the amount payable is effective (in the case of an Early
     Termination Date which is designated as a result of a Termination Event).
     Such amount will be paid together with (to the extent permitted under
     applicable law) interest thereon (before as well as after judgment), from
     (and including) the relevant Early Termination Date to (but excluding) the
     date such amount is paid, at the Applicable Rate.  Such interest will be
     calculated on the basis of daily compounding and the actual number of days
     elapsed.

(e)  Payments on Early Termination. If an Early Termination Date occurs, the
     following provisions shall apply based on the parties' election in the
     Schedule of a payment measure, either

                                      -17-


     "Market Quotation" or "Loss", and a payment method, either the "First
     Method" or the "Second Method". If the parties fail to designate a payment
     measure or payment method in the Schedule, it will be deemed that "Market
     Quotation" or the "Second Method", as the case may be, shall apply. The
     amount, if any, payable in respect of an Early Termination Date and
     determined pursuant to this Section will be subject to any Set-off.

     (i) Events of Default. If the Early Termination Date results from an Event
     of Default:

          (1) First Method and Market Quotation. If the First Method and Market
          Quotation apply, the Defaulting Party will pay to the Non-defaulting
          Party the excess, if a positive number, of (A) the sum of the
          Settlement Amount (determined by the Non-defaulting Party) in respect
          of the Terminated Transactions and the Unpaid Amounts owing to the
          Non-defaulting Party over (B) the Unpaid Amounts owing to the
          Defaulting Party.

          (2) First Method and Loss. If the First Method and Loss apply, the
          Defaulting Party will pay to the Non-defaulting Party, if a positive
          number, the Non-defaulting Party's Loss in respect of this Agreement.

          (3) Second Method and Market Quotation. If the Second Method and
          Market Quotation apply, an amount will be payable equal to (A) the sum
          of the Settlement Amount (determined by the Non-defaulting Party) in
          respect of the Terminated Transactions and the Unpaid Amounts owing to
          the Non-defaulting Party less (B) the Unpaid Amounts owing to the
          Defaulting Party. If that amount is a positive number, the Defaulting
          Party will pay it to the Non-defaulting Party; if it is a negative
          number, the Non-defaulting Party will pay the absolute value of that
          amount to the Defaulting Party.

          (4) Second Method and Loss. If the Second Method and Loss apply, an
          amount will be payable equal to the Non-defaulting Party's Loss in
          respect of this Agreement. If that amount is a positive number, the
          Defaulting Party will pay it to the Non-defaulting Party; if it is a
          negative number, the Non-defaulting Party will pay the absolute value
          of that amount to the Defaulting Party.

     (ii) Termination Events. If the Early Termination Date results from a
Termination Event:

          (1) One Affected Party. If there is one Affected Party, the amount
          payable will be determined in accordance with Section 6(e)(i)(3), if
          Market Quotation applies, or Section 6(e)(i)(4), if Loss applies,
          except that, in either case, references to the Defaulting Party and to
          the Non-defaulting Party will be deemed to be references to the
          Affected Party and the party which is not the Affected Party,
          respectively, and, if Loss applies and fewer than all the Transactions
          are being terminated, Loss shall be calculated in respect of all
          Terminated Transactions.

                                      -18-


          (2) Two Affected Parties. If there are two Affected Parties:

              (A) if Market Quotation applies, each party will determine a
              Settlement Amount in respect of the Terminated Transactions, and
              an amount will. be payable equal to (1) the sum of (a) one-half of
              the difference between the Settlement Amount of the party with the
              higher Settlement Amount CW') and the. Settlement Amount of the
              party with the lower Settlement Amount ("Y") and (b) the Unpaid
              Amounts owing to X less (H) the Unpaid Amounts owing to Y; and

               (B) if Loss applies, each party will determine its Loss in
               respect of this Agreement (or, if fewer than all the Transactions
               are being terminated, in respect of all Terminated Transactions)
               and an amount will be payable equal to one-half of the difference
               between the Loss of the party with the higher Loss (")C') and the
               Loss of the party with the lower Loss ("Y").

     If the amount payable is a positive number, Y will pay it to X; if it is a
     negative number, X will pay the absolute value of that amount to Y.

     (iii)  Adjustment for Bankruptcy. In circumstances where an Early
     Termination Date occurs because "Automatic Early Termination" applies in
     respect of a party, the amount determined under this Section 6(e) will be
     subject to such adjustments as are appropriate and permitted by law to
     reflect any payments or deliveries made by one party to the other under
     this Agreement (and retained by such other party) during the period from
     the relevant Early Termination Date to the date for payment determined
     under Section 6(d)(ii).

     (iv) Pre-Estimate. The parties agree that if Market Quotation applies an
     amount recoverable under this Section 6(e) is a reasonable pre-estimate of
     loss and not a penalty. Such amount is payable for the loss of bargain and
     the loss of protection against future risks and except as otherwise
     provided in this Agreement neither party will be entitled to recover any
     additional damages as a consequence of such losses.

7.   Transfer

Neither this Agreement nor any interest or obligation in or under this Agreement
may be transferred (whether by way of security or otherwise) by either party
without the prior written consent of the other party, except that:

(a)  a party may make such a transfer of this Agreement pursuant to a
     consolidation or amalgamation with, or merger with or into, or transfer of
     ail or substantially all its assets to, another entity (but without
     prejudice to any other right or remedy under this Agreement); and

                                      -19-


(b)  a party may make such a transfer of all or any part of its interest in any
     amount payable to it from a Defaulting Party under Section 6(e).

Any purported transfer that is not in compliance with this Section will be void.

8.   Miscellaneous

(a)  Entire Agreement. This Agreement constitutes the entire agreement and
     understanding of the parties with respect to its subject matter and
     supersedes all oral communication and prior writings with respect thereto.

(b)  Amendments. No amendment, modification or waiver in respect of this
     Agreement will be effective unless in writing (including a writing
     evidenced by a facsimile transmission) and executed by each of the parties
     or confirmed by an exchange of telexes or electronic messages on an
     electronic messaging system.

(c)  Survival of Obligations. Without prejudice to Sections 2(a)(iii) and
     6(c)(ii), the obligations of the parties under this Agreement will survive
     the termination of any Transaction.

(d)  Remedies Cumulative. Except as provided in this Agreement, the rights,
     powers, remedies and privileges provided in this Agreement are cumulative
     and not exclusive of any rights, powers, remedies and privileges provided
     by law.

(e)  Counterparts and Confirmations.

     (i) This Agreement (and each amendment, modification and waiver in respect
     of it) may be executed and delivered in counterparts (including by
     facsimile transmission), each of which will be deemed an original

     (ii) The parties intend that they are legally bound by the terms of each
     Transaction from the moment they agree to those terms (whether- orally or
     otherwise). A Confirmation shall be entered into as soon as practicable and
     may be executed and delivered in counterparts (including by facsimile
     transmission) or be created by an exchange of telexes or by an exchange of
     electronic messages on an electronic messaging system, which in each case
     will be sufficient for all purposes to evidence a binding supplement to
     this Agreement. The parties will specify therein or through another
     effective means that any such counterpart, telex or electronic message

Transaction or group of Terminated Transactions are to be excluded but, without
limitation, any payment or delivery that would, but for the relevant Early
Termination Date, have been required (assuming satisfaction of each applicable
condition precedent) after that Early Termination Date is to be included. The
Replacement Transaction would be subject to such documentation as such party and
the Reference Market-maker may, in good faith, agree. The party making the
determination (or its agent) will request each Reference Market-maker to provide
its quotation to the extent reasonably practicable as of the same day and time
(without regard to different time zones) on or as soon as reasonably practicable
after the relevant Early Termination Date. The day and time as of which those
quotations are to be obtained will be selected in good faith by the party
obliged to make a determination under Section 6(e), and, if each party is so
obliged, after consultation with the other. If more than three quotations are
provided, the Market Quotation will be the arithmetic mean of the quotations,
without regard to the quotations having the highest and lowest values. If
exactly three such quotations are provided, the Market Quotation will be the
quotation remaining after disregarding the highest and lowest quotations. For
this purpose, if more than one quotation has the same highest value or lowest

quotations are provided, it will be deemed that the Market Quotation in respect
of such Terminated Transaction or group of Terminated Transactions cannot be
determined.

evidence of any actual cost) to the Non-defaulting Party (as certified by it) if

the lapse of time or both, would constitute an Event of Default.

an extension of credit and (b) to the extent practicable, from among such
dealers having an office in the same city.

made under Section 2(a)(i) with respect to a Transaction-

on, such payer.

"Settlement Amount" means, with respect to a party and any Early Termination
Date, the sum of:-

                                      -25-

     Transaction or group of Terminated Transactions for which a Market
     Quotation is determined; and

     any Unpaid Amounts) for each Terminated Transaction or group of Terminated

     commercially reasonable result.

Transaction in this Agreement or the relevant confirmation.

Termination Date (or, if "Automatic Early Termination" applies, immediately
before that Early Termination Date).

Date, the aggregate of (a) in respect of all Terminated Transactions, the

Termination Date and which remain unpaid as at such Early Termination Date and
(b) in respect of each Terminated Transaction, for each obligation under Section
2(a)(i) which was (or

                                      -26-


would have been but for Section 2(a)(iii)) required to be settled by delivery to
such party on or prior to such Early Termination Date and which has not been so
settled as at such Early Termination Date, an amount equal to the fair market
value of that which was (or would have been) required to be delivered as of the
originally scheduled date for delivery, in each case together with (to the
extent permitted under applicable law) interest, in the currency of such
amounts, from (and including) the date such amounts or obligations were or would
have been required to have been paid or performed to (but excluding) such Early
Termination Date, at the Applicable Rate. Such amounts of interest will be
calculated on the basis of daily compounding and the actual number of days
elapsed. The fair market value of any obligation referred to in clause (b) above
shall be reasonably determined by the party obliged to make the determination
under Section 6(e) or, if each party is so obliged, it shall be the average of
the fair market values reasonably determined by both parties.

     and payable by it under Section 6(e) of this Agreement, any Other
     Obligations of the Defaulting or Affected Party; and (y) against any of its

     notice to the other Party, but shall notify the other Party promptly, after
     any exercise of such rights. If the amount of any Other Obligation Set-off

     appropriate adjustment. The Set-off rights of each Party hereunder shall be

     other set-off rights, as such Party may have by contract, operation of law,
     in equity or otherwise. As used herein, the term "Other Obligations- means,
     with respect to either Party, any amount payable by it or any of its
     Affiliates to the other Party, whether such amount is payable-under this
     Agreement, another contract, applicable law or otherwise, and whether such
     amount is due at the time in question, in the future or subject to a.
     contingency.

     unless the other Party ("Y") is required pursuant to appropriate
     proceedings to return to X or otherwise returns to X upon demand of X any
     portion of any such payment or delivery, (i) the occurrence of an event
     described in Section 5(a) of this Agreement with respect to X, any Credit
