                                MASTER AGREEMENT
                            dated as of June 10, 1999



CHICAGO BRIDGE & IRON COMPANY NV and  BANK OF MONTREAL

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 14 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 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 Offices through which the parties make and receive
payments or deliveries.

(d)        DEDUCTION OR WITHHOLDING FOR TAX.

           (i) GROSS-UP. All payments under this Agreement will be made without
           any deduction or withholding for. or on account of any Tax unless
           such deduction or withholding is required by any applicable law, as
           modified by the practice of any relevant governmental revenue
           authority, then in effect. If a party is so required to deduct or
           withhold, then that party ("X") will:--

               (1)  promptly notify the other party ("Y") of such requirement;

               (2) pay to the relevant authorities the full amount required to
               be deducted or withheld (including the full amount required to be
               deducted or withheld from any additional amount paid by X to Y
               under this Section 2(d)) promptly upon the earlier of determining
               that such deduction or withholding is required or receiving
               notice that such amount has been assessed against Y;

               (3) promptly forward to Y an official receipt (or a certified
               copy), or other documentation reasonably acceptable to Y,
               evidencing such payment to such authorities; and

               (4) if such Tax is an Indemnifiable Tax, pay to Y, in addition to
               the payment to which Y is otherwise entitled under this
               Agreement, such additional amount as is necessary to ensure that
               the net amount actually received by Y (free and clear of
               Indemnifiable Taxes, whether assessed against X or Y) will equal
               the full amount Y would have received had no such deduction or
               withholding been required. However, X will not be required to pay
               any additional amount to Y to the extent that it would not be
               required to be paid but for:--

                    (A) the failure by Y to comply with or perform any agreement
                    contained in Section 4(a)(i), 4(a)(iii) or 4(d); or

                    (B) the failure of a representation made by Y pursuant to
                    Section 3(f) to be accurate and true unless such failure
                    would not have occurred but for (I) any action taken by a
                    taxing authority, or brought in a court of competent
                    jurisdiction, on or after the date on which a Transaction is
                    entered into (regardless of whether such action is taken or
                    brought with respect to a party to this Agreement) or (II) a
                    Change in Tax Law.


                                       2                             ISDA(R)1992

   3

         (ii)  LIABILITY. If: --

               (1)   X is required by any applicable law, as modified by the
                     practice of any relevant governmental revenue authority, to
                     make any deduction or withholding in respect of which X
                     would not be required to pay an additional amount to Y
                     under Section 2(d)(i)(4);

               (2)   X does not so deduct or withhold; and

               (3)   a liability resulting from such Tax is assessed directly
                     against X,

         then, except to the extent Y has satisfied or then satisfies the
         liability resulting from such Tax, Y will promptly pay to X the amount
         of such liability (including any related liability for interest, but
         including any related liability for penalties only if Y has failed to
         comply with or perform any agreement contained in Section 4(a)(i),
         4(a)(iii) or 4(d)).

(e)      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 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
and, in the case of the representations in Section 3(f), at all times until the
termination of this Agreement) that:--

         Provider of such party consolidates or amalgamates with, or merges with
         or into, or transfers all or substantially all 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.

(h)      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, a Tax Event if the event is specified in
(ii) below or a Tax Event Upon Merger if the event is specified in (iii) below,
and, if specified to be applicable, a Credit Event Upon Merger if the event is
specified pursuant to (iv) below or an Additional Termination Event if the event
is specified pursuant to (v) 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



                                       6                             ISDA(R)1992


   7

         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) TAX EVENT. Due to (x) any action taken by a taxing authority, or
         brought in a court of competent jurisdiction, on or after the date on
         which a Transaction is entered into (regardless of whether such action
         is taken or brought with respect to a party to this Agreement) or (y) a
         Change in Tax Law, the party (which will be the Affected Party) will,
         or there is a substantial likelihood that it will, on the next
         succeeding Scheduled Payment Date (1) be required to pay to the other
         party an additional amount in respect of an Indemnifiable Tax under
         Section 2(d)(i)(4) (except in respect of interest under Section 2(e),
         6(d)(ii) or 6(e)) or (2) receive a payment from which an amount is
         required to be deducted or withheld for or on account of a Tax (except
         in respect of interest under Section 2(e), 6(d)(ii) or 6(e)) and no
         additional amount is required to be paid in respect of such Tax under
         Section 2(d)(i)(4) (other than by reason of Section 2(d)(i)(4)(A) or
         (B));

         (iii) TAX EVENT UPON MERGER. The party (the "Burdened Party") on the
         next succeeding Scheduled Payment Date will either (1) be required to
         pay an additional amount in respect of an Indemnifiable Tax under
         Section 2(d)(i)(4) (except in respect of interest under Section 2(e),
         6(d)(ii) or 6(e)) or (2) receive a payment from which an amount has
         been deducted or withheld for or on account of any Indemnifiable Tax in
         respect of which the other party is not required to pay an additional
         amount (other than by reason of Section 2(d)(i)(4)(A) or (B)), in
         either case as a result of a party consolidating or amalgamating with,
         or merging with or into, or transferring all or substantially all its
         assets to, another entity (which will be the Affected Party) where such
         action does not constitute an event described in Section 5(a)(viii);

         (iv) 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)(vii)
         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

         (v) 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 an 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



                                       7                             ISDA(R)1992


   8

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) TRANSFER TO AVOID TERMINATION EVENT. If either an Illegality under
         Section 5(b)(i)(1) or a Tax Event occurs and there is only one Affected
         Party, or if a Tax Event Upon Merger occurs and the Burdened Party is
         the Affected Party, the Affected Party will, as a condition to its
         right to designate an Early Termination Date under Section 6(b)(iv),
         use all reasonable efforts (which will not require such party to incur
         a loss, excluding immaterial, incidental expenses) to transfer within
         20 days after it gives notice under Section 6(b)(i) all its rights and
         obligations under this Agreement in respect of the Affected
         Transactions to another of its Offices or Affiliates so that such
         Termination Event ceases to exist.

         If the Affected Party is not able to make such a transfer it will give
         notice to the other party to that effect within such 20 day period,
         whereupon the other party may effect such a transfer within 30 days
         after the notice is given under Section 6(b)(i).

         Any such transfer by a party under this Section 6(b)(ii) will be
         subject to and conditional upon the prior written consent of the other
         party, which consent will not be withheld if such other party's
         policies in effect at such time would permit it to enter into
         transactions with the transferee on the terms proposed.

         (iii) TWO AFFECTED PARTIES. If an Illegality under Section 5(b)(i)( 1)
         or a Tax Event 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.

         (iv)  RIGHT TO TERMINATE. If:--

               (l) a transfer under Section 6(b)(ii) or an agreement under
               Section 6(b)(iii), as the case may be, 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 under Section 5(b)(i)(2), a Credit Event Upon
               Merger or an Additional Termination Event occurs, or a Tax Event
               Upon Merger occurs and the Burdened Party is not the Affected
               Party,

         either party in the case of an Illegality, the Burdened Party in the
         case of a Tax Event Upon Merger, any Affected Party in the case of a
         Tax Event or 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(e) 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


                                       8                             ISDA(R)1992

   9


         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) in the Termination Currency, 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 "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 MARKER 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
               Termination Currency Equivalent of the Unpaid Amounts owing to
               the Non-defaulting Party over (B) the Termination Currency
               Equivalent of 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 Termination Currency Equivalent of the Unpaid Amounts
               owing to the Non-defaulting Party less (B) the Termination
               Currency Equivalent of 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: --


                                       9                             ISDA(R)1992

   10

               (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.

               (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 (I) the sum of (a)
                    one-half of the difference between the Settlement Amount of
                    the party with the higher Settlement Amount ("X") and the
                    Settlement Amount of the party with the lower Settlement
                    Amount ("Y") and (b) the Termination Currency Equivalent of
                    the Unpaid Amounts owing to X less (II) the Termination
                    Currency Equivalent of 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 ("X") 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

Subject to Section 6(b)(ii), 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 all
or substantially all its assets to, another entity (but without prejudice to any
other right or remedy under this Agreement); and

(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.       CONTRACTUAL CURRENCY

(a)      PAYMENT IN THE CONTRACTUAL CURRENCY. Each payment under this Agreement
will be made in the relevant currency specified in this Agreement for that
payment (the "Contractual Currency"). To the extent permitted by applicable law,
any obligation to make payments under this Agreement in the Contractual Currency
will not be discharged or satisfied by any tender in any currency other than the
Contractual Currency, except to the extent



                                       10                            ISDA(R)1992


   11

such tender results in the actual receipt by the party to which payment is owed,
acting in a reasonable manner and in good faith in converting the currency so
tendered into the Contractual Currency, of the full amount in the Contractual
Currency of all amounts payable in respect of this Agreement. If for any reason
the amount in the Contractual Currency so received falls short of the amount in
the Contractual Currency payable in respect of this Agreement, the party
required to make the payment will, to the extent permitted by applicable law,
immediately pay such additional amount in the Contractual Currency as may be
necessary to compensate for the shortfall. If for any reason the amount in the
Contractual Currency so received exceeds the amount in the Contractual Currency
payable in respect of this Agreement, the party receiving the payment will
refund promptly the amount of such excess.

(b)      JUDGMENTS. To the extent permitted by applicable law, if any judgment
or order expressed in a currency other than the Contractual Currency is rendered
(i) for the payment of any amount owing in respect of this Agreement, (ii) for
the payment of any amount relating to any early termination in respect of this
Agreement or (iii) in respect of a judgment or order of another court for the
payment of any amount described in (i) or (ii) above, the party seeking
recovery, after recovery in full of the aggregate amount to which such party is
entitled pursuant to the judgment or order, will be entitled to receive
immediately from the other party the amount of any shortfall of the Contractual
Currency received by such party as a consequence of sums paid in such other
currency and will refund promptly to the other party any excess of the
Contractual Currency received by such party as a consequence of sums paid in
such other currency if such shortfall or such excess arises or results from any
variation between the rate of exchange at which the Contractual Currency is
converted into the currency of the judgment or order for the purposes of such
judgment or order and the rate of exchange at which such party is able, acting
in a reasonable manner and in good faith in converting the currency received
into the Contractual Currency, to purchase the Contractual Currency with the
amount of the currency of the judgment or order actually received by such party.
The term "rate of exchange" includes, without limitation, any premiums and costs
of exchange payable in connection with the purchase of or conversion into the
Contractual Currency.

(c)      SEPARATE INDEMNITIES. To the extent permitted by applicable law, these
indemnities constitute separate and independent obligations from the ocher
obligations in this Agreement, will be enforceable as separate and independent
causes of action, will apply notwithstanding any indulgence granted by the party
to which any payment is owed and will not be affected by judgment being obtained
or claim or proof being made for any other sums payable in respect of this
Agreement.

(d)      EVIDENCE OF LOSS. For the purpose of this Section 8, it will be
sufficient for a party to demonstrate that it would have suffered a loss had an
actual exchange or purchase been made.

9.       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



                                       11                            ISDA(R)1992


   12

         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
         constitutes a Confirmation.

(f)      NO WAIVER OF RIGHTS. A failure or delay in exercising any right, power
or privilege in respect of this Agreement will not be presumed to operate as a
waiver, and a single or partial exercise of any right, power or privilege will
not be presumed to preclude any subsequent or further exercise, of that right,
power or privilege or the exercise of any other right, power or privilege.

(g)      HEADINGS. The headings used in this Agreement are for convenience of
reference only and are not to affect the construction of or to be taken into
consideration in interpreting this Agreement.

10.      OFFICES; MULTIBRANCH PARTIES

(a)      If Section 10(a) is specified in the Schedule as applying, each party
that enters into a Transaction through an Office other than its head or home
office represents to the other party that, notwithstanding the place of booking
office or jurisdiction of incorporation or organisation of such party, the
obligations of such party are the same as if it had entered into the Transaction
through its head or home office. This representation will be deemed to be
repeated by such party on each date on which a Transaction is entered into.

(b)      Neither party may change the Office through which it makes and receives
payments or deliveries for the purpose of a Transaction without the prior
written consent of the other party.

(c)      If a party is specified as a Multibranch Party in the Schedule, such
Multibranch Party may make and receive payments or deliveries under any
Transaction through any Office listed in the Schedule, and the Office through
which it makes and receives payments or deliveries with respect to a Transaction
will be specified in the relevant Confirmation.

11.      EXPENSES

A Defaulting Party will, on demand, indemnify and hold harmless the other party
for and against all reasonable out-of-pocket expenses, including legal fees and
Stamp Tax, incurred by such other party by reason of the enforcement and
protection of its rights under this Agreement or any Credit Support Document to
which the Defaulting Party is a party or by reason of the early termination of
any Transaction, including, but not limited to, costs of collection.

12.       NOTICES

(a) EFFECTIVENESS. Any notice or other communication in respect of this
Agreement may be given in any manner set forth below (except that a notice or
other communication under Section 5 or 6 may not be given by facsimile

   13

         (v) if sent by electronic messaging system, on the date that electronic
         message is received,

unless the date of that delivery (or attempted delivery) or that receipt, as
applicable, is not a Local Business Day or that communication is delivered (or

Business Day, in which case that communication shall be deemed given and
effective on the first following day that is a Local Business Day.

(b)      CHANGE OF ADDRESSES. Either party may by notice to the other change the
address, telex or facsimile number or electronic messaging system details at
which notices or other communications are to be given to it.

13.      GOVERNING LAW AND JURISDICTION

(a)      GOVERNING LAW. This Agreement will be governed by and construed in
accordance with the law specified in the Schedule.

         to this Agreement ("Proceedings"), each party irrevocably: --

         (i) submits to the jurisdiction of the English courts, if this
         Agreement is expressed to be governed by English law, or to the
         non-exclusive jurisdiction of the courts of the State of New York and
         the United States District Court located in the Borough of Manhattan in
         New York City, if this Agreement is expressed to be governed by the
         laws of the State of New York; and

         (ii) waives any objection which it may have at any time to the laying
         of venue of any Proceedings brought in any such court, waives any claim
         that such Proceedings have been brought in an inconvenient forum and
         further waives the right to object, with respect to such Proceedings,
         that such court does not have any jurisdiction over such party.

Nothing in this Agreement precludes either party from bringing Proceedings in
any other jurisdiction (outside, if this Agreement is expressed to be governed
by English law, the Contracting States, as defined in Section 1(3) of the Civil
Jurisdiction and Judgments Act 1982 or any modification, extension or
re-enactment thereof for the time being in force) nor will the bringing of
Proceedings in any one or more jurisdictions preclude the bringing of
Proceedings in any other jurisdiction.

(c)      SERVICE OF PROCESS. Each party irrevocably appoints the Process Agent
(if any) specified opposite its name in the Schedule to receive, for it and on
its behalf, service of process in any Proceedings. If for any reason any party's
Process Agent is unable to act as such, such party will promptly notify the
other party and within 30 days appoint a substitute process agent acceptable to
the other party. The parties irrevocably consent to service of process given in
the manner provided for notices in Section 12. Nothing in this Agreement will
affect the right of either party to serve process in any other manner permitted
by law.

(d)      WAIVER OF IMMUNITIES. Each party irrevocably waives, to the fullest
extent permitted by applicable law, with respect to itself and its revenues and
assets (irrespective of their use or intended use), all immunity on the grounds
of sovereignty or other similar grounds from (i) suit, (ii) jurisdiction of any
court, (iii) relief by way of injunction, order for specific performance or for
recovery of property, (iv) attachment of its assets (whether before or after
judgment) and (v) execution or enforcement of any judgment to which it or its
revenues or assets might otherwise be entitled in any Proceedings in the courts
of any jurisdiction and irrevocably agrees, to the extent permitted by
applicable law, that it will not claim any such immunity in any Proceedings.

incorporated by reference, in this Agreement, (b) in relation to any other

the place where the relevant new account is to be located and (d) in relation to
Section 5(a)(v)(2), in the relevant locations for performance with respect to
such Specified Transaction.

"LOSS" means, with respect to this Agreement or one or more Terminated
Transactions, as the case may be, and a party, the Termination Currency
Equivalent of an amount that party reasonably determines in good faith to be its
total losses and costs (or gain, in which case expressed as a negative number)
in connection with this Agreement or that Terminated Transaction or group of
Terminated Transactions, as the case may be, including any loss of bargain, cost
of funding or, at the election of such party but without duplication, loss or
cost incurred as a result of its terminating, liquidating, obtaining or
reestablishing any hedge or related trading position (or any gain resulting from
any of them). Loss includes losses and costs (or gains) in respect of any
payment or delivery required to have been made (assuming satisfaction of each
applicable condition precedent) on or before the relevant Early Termination Date
and not made, except, so as to avoid duplication, if Section 6(e)(i)(l) or (3)
or 6(e)(ii)(2)(A) applies. Loss does not include a party's legal fees and
out-of-pocket expenses referred to under Section 11. A party will determine its
Loss as of the relevant Early Termination Date, or, if that is not reasonably
practicable, as of the earliest date thereafter as is reasonably practicable. A
party may (but need not) determine its Loss by reference to quotations of
relevant rates or prices from one or more leading dealers in the relevant
markets.

"MARKET QUOTATION" means, with respect to one or more Terminated Transactions
and a party making the determination, an amount determined on the basis of
quotations from Reference Market-makers. Each quotation will be for an amount,
if any, that would be paid to such party (expressed as a negative number) or by
such party (expressed as a positive number) in consideration of an agreement
between such party (taking into account any existing Credit Support Document
with respect to the obligations of such party) and the quoting Reference
Market-maker to enter into a transaction (the "Replacement Transaction") that
would have the effect of preserving for such party the economic equivalent of
any payment or delivery (whether the underlying obligation was absolute or
contingent and assuming the satisfaction of each applicable condition precedent)
by the parties under Section 2(a)(i) in respect of such Terminated Transaction
or group of Terminated Transactions that would, but for the occurrence of the
relevant Early Termination Date, have been required after that date. For this
purpose, Unpaid Amounts in respect of the Terminated 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 value, then one of such
quotations shall be disregarded. If fewer than three 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.

"NON-DEFAULT RATE" means a rate per annum equal to the cost (without proof or
evidence of any actual cost) to the Non-defaulting Party (as certified by it) if
it were to fund the relevant amount.

"NON-DEFAULTING PARTY" has the meaning specified in Section 6(a).

"OFFICE" means a branch or office of a party, which may be such party's head or
home office.

"POTENTIAL EVENT OF DEFAULT" means any event which, with the giving of notice or
the lapse of time or both, would


                                       15                            ISDA(R)1992

   16


constitute an Event of Default.

"REFERENCE MARKET-MAKERS" means four leading dealers in the relevant market
selected by the party determining a Market Quotation in good faith (a) from
among dealers of the highest credit standing which satisfy all the criteria that

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

"RELEVANT JURISDICTION" means, with respect to a party, the jurisdictions (a) in
which the party is incorporated, organised, managed and controlled or considered
to have its seat, (b) where an Office through which the party is acting for
purposes of this Agreement is located, (c) in which the party executes this
Agreement and (d) in relation to any payment, from or through which such payment
is made.

"SCHEDULED PAYMENT DATE" means a date on which a payment or delivery is to be
made under Section 2(a)(i) with respect to a Transaction.

"SET-OFF" means set-off, offset, combination of accounts, right of retention or
withholding or similar right or requirement to which the payer of an amount
under Section 6 is entitled or subject (whether arising under this Agreement,
another contract, applicable law or otherwise) that is exercised by, or imposed
on, such payer.

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

(a) the Termination Currency Equivalent of the Market Quotations (whether
positive or negative) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation is determined; and

(b) such party's Loss (whether positive or negative and without reference to any
Unpaid Amounts) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation cannot be determined or would not Cm
the reasonable belief of the party making the determination) produce a
commercially reasonable result.

"SPECIFIED ENTITY" has the meaning specified in the Schedule.

"SPECIFIED INDEBTEDNESS" means, subject to the Schedule, any obligation (whether
present or future, contingent or otherwise, as principal or surety or otherwise)
in respect of borrowed money.

"SPECIFIED TRANSACTION" means, subject to the Schedule, (a) any transaction
(including an agreement with respect thereto) now existing or hereafter entered
into between one party to this Agreement (or any Credit Support Provider of such
party or any applicable Specified Entity of such party) and the other party to
this Agreement (or any Credit Support Provider of such other party or any
applicable Specified Entity of such other party) which is a rate swap
transaction, 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, 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), (b) any combination of
these transactions and (c) any other transaction identified as a Specified
Transaction in this Agreement or the relevant confirmation.

"STAMP TAX" means any stamp, registration, documentation or similar tax.

"TAX" means any present or future tax, levy, impost, duty, charge, assessment or
fee of any nature (including interest, penalties and additions thereto) that is

tax.

"TAX EVENT UPON MERGER" has the meaning specified in Section 5(b).

resulting from an Event of Default, all Transactions (in either case) in



                                       16                            ISDA(R)1992


   17

effect immediately before the effectiveness of the notice designating that Early
Termination Date (or, if "Automatic Early Termination" applies, immediately
before that Early Termination Date).

"TERMINATION CURRENCY" has the meaning specified in the Schedule.

"TERMINATION CURRENCY EQUIVALENT" means, in respect of any amount denominated in
the Termination Currency, such Termination Currency amount and, in respect of
any amount denominated in a currency other than the Termination Currency (the
"Other Currency"), the amount in the Termination Currency determined by the
party making the relevant determination as being required to purchase such
amount of such Other Currency as at the relevant Early Termination Date, or, if
the relevant Market Quotation or Loss (as the case may be), is determined as of
a later date, that later date, with the Termination Currency at the rate equal
to the spot exchange rate of the foreign exchange agent (selected as provided
below) for the purchase of such Other Currency with the Termination Currency at
or about 11:00 a.m. (in the city in which such foreign exchange agent is
located) on such date as would be customary for the determination of such a rate
for the purchase of such Other Currency for value on the relevant Early
Termination Date or that later date. The foreign exchange agent will, if only
one party is obliged to make a determination under Section 6(e), be selected in
good faith by that party and otherwise will be agreed by the parties.

Date, the aggregate of (a) in respect of all Terminated Transactions, the
amounts that became payable (or that would have become payable but for Section
2(a)(iii)) to such party under Section 2(a)(i) on or prior to such Early
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 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 Termination Currency Equivalents of the fair market
values reasonably determined by both parties.

dates specified below with effect from the date specified on the first page of

                       [Letterhead of Netherlands Counsel]


                                                                  [Date]

Attention: Senior Counsel


Dear Sirs:

                  This opinion is furnished to you in connection with the ISDA
Master Agreernent dated as of [DATE] (the "Agreement") between Chicago Bridge &
Iron Company N.y. ("Counterparty") and Bank of Montreal (the "Bank"), and the
Equity Forward Transaction dated as of [DATE] (the "Transaction") entered into
by the Counterparty and the Bank pursuant to the Agreement. Terms defined in the
Agreement and used but not defined herein have the meanings given to them in the
Agreement.

                  We have acted as counsel to the Counterparty in connection
with the execution and delivery of the Agreement and in connection with the
Transaction. We have examined the Agreement, including the Confirmation for the
Transaction (the "Confirmation"), the Counterparty's constating documents and
such other documents as we have deemed necessary or appropriate for purposes of
the opinions expressed herein. We have also made such investigations and
considered such questions of law as we have considered necessary for the
purposes of rendering this opinion. In such examination we have assumed the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals and the conformity to original documents of all documents submitted
to us as copies, certified or otherwise.

                  We express no opinion with respect to the laws of any
jurisdiction other than the laws of the Netherlands.

         Based on the foregoing we are of the opinion that:

         1.   The Counterparty has been duly incorporated and organized and is
              validly existing and in good standing under the laws of the
              Netherlands.

         2.   The execution and delivery of the Agreement and the Confirmation
              by the Counterparty and the performance by the Counterparty of its
              obligations thereunder are within the corporate power of the
              Counterparty and do not conflict with or result in a breach of the
              constating documents of the Counterparty or of any law or
              regulation or of any agreement, decree, order, judgment,
              injunction or other instrument binding on or affecting the
              Counterparty.

         3.   All necessary and proper proceedings have been taken by the
              Counterparty to duly authorize the execution and delivery of the
              Agreement and the Confirmation to the Bank, including for the
              avoidance of doubt, all corporate action required pursuant to
              Section 2:98 Dutch Civil Code.




                                       26

         4.   No action by, notice to or filing with, or consent, authorization
              or approval of, any governmental authority or regulatory body is
              required in connection with the Counterparty's execution, delivery
              and performance of the Agreement and the Confirmation.

         5.   The governing law clause, subjecting the Agreement to New York
              law, is valid under the laws of the Netherlands. Under the laws of
              the Netherlands, New York law will be applied to the Agreement,
              provided that such choice of law is bona fide and provided that
              such choice of law is not contrary to public policy, as that term
              is understood under the laws of the Netherlands. To the best of
              our knowledge, having made due inquiry, public policy would not be
              breached by application of the chosen law.

         6.   Assuming that the Agreement and the Confirmation are legal, valid
              and binding and enforceable under New York law, the Agreement and
              the Confirmation constitute legal, valid and binding obligations
              of the Counterparty enforceable in accordance with their terms and
              the laws of the Netherlands.

         The foregoing opinions are subject to the following qualifications:

         1.   The enforceability of the Agreement and the Confirmation against
              the Counterparty is subject to applicable bankruptcy, insolvency,
              reorganization, moratorium, and other similar laws and equitable
              principles of general application affecting the rights of
              creditors, as well, as to the availability of specific
              performance, injunctive relief or any other equitable remedy; and

         2.   The assumption that the Agreement and the Confirmation have been
              authorized, executed and delivered by, and constitutes a legal,
              valid and binding obligation of the Bank.


         This opinion is provided solely for your benefit and is not to be
relied upon for any purpose other than in respect of the Agreement and the
Confirmation, or by any other person.

         Yours very truly,

                                     which settlement of a sale of such Shares
                                     executed on that Forward Settlement Date
                                     customarily would take place through the
                                     relevant Clearance System, unless a
                                     Settlement Disruption Event prevents
                                     delivery of such Shares on that


   29

                                       3

                                     day. If a Settlement Disruption Event does
                                     prevent delivery on that day, then the
                                     Settlement Date will be the first
                                     succeeding day on which delivery of the

                                     Clearance System unless a Settlement
                                     Disruption Event prevents settlement on
                                     each of the 10 relevant Clearance System
                                     Business Days immediately following the
                                     original date that, but for the Settlement
                                     Disruption Event, would have been the
                                     Settlement Date. In that case, (a) if such
                                     Shares can be delivered in any other
                                     commercially reasonable manner, then the
                                     Settlement Date will be the first day on
                                     which settlement of a sale of Shares
                                     executed on that 10th relevant Clearance
                                     System Business Day customarily would take
                                     place using such other commercially
                                     reasonable manner of delivery (which other
                                     manner of delivery will be deemed the
                                     relevant Clearance System for the purposes
                                     of delivery of the relevant Shares), and
                                     (b) if such Shares cannot be delivered in
                                     any other commercially reasonable manner,
                                     then the Settlement Date will be postponed
                                     until delivery can be effected through the
                                     relevant Clearance System or in any other
                                     commercially reasonable manner.

         Dividends:                  (a)  "Dividend Payment Date" means March
                                          30, June 30, September 30 and December
                                          30 of each calendar year during the
                                          term of this Transaction, subject to
                                          adjustment in accordance with the
                                          Following Business Day Convention.

                                     (b)  "Dividend Amount" means, in respect of
                                          each Dividend Payment Date, an amount
                                          calculated by the Calculation Agent,
                                          equal to $0.06 minus the amount of any
                                          dividend per Share declared to be
                                          payable by the Issuer for such
                                          Dividend Payment Date, multiplied by
                                          the Number of Shares to be Delivered.

                                     (c)  If the Dividend Amount so calculated
                                          is a positive number, then Party A
                                          will pay such Dividend Amount to Party
                                          B on the Dividend Payment Date. If the
                                          Dividend Amount so calculated by the
                                          Calculation Agent is a negative
                                          number, then Party B will pay the
                                          absolute value of such Dividend Amount
                                          to Party A on the Dividend Payment
                                          Date.

Adjustments:                         Upon the occurrence of an event having, in
                                     the determination of the Calculation Agent,
                                     a diluting or concentrative effect on

                                     the theoretical value of the Shares, then
                                     following the declaration by the Issuer of
                                     the Shares of the terms of any Potential
                                     Adjustment Event, the Calculation Agent
                                     will make the corresponding adjustments to
                                     the Forward Price and Number of Shares to
                                     be Delivered, and to any other variable
                                     relevant to the settlement or payment terms
                                     of the Transaction as the Calculation Agent
                                     determines appropriate to account for that
                                     diluting or concentrative effect, and will
                                     determine the effective date(s) of the
                                     adjustment(s).

11.      Additional Termination Events:

         (a)  In addition to the Termination Events set forth in the Agreement,
              it shall be a Termination Event, with Party B as the sole Affected
              Party and this Transaction (after consideration of any partial
              delivery) the sole Affected Transaction, if Party B


   36
                                       10

              is unable to deliver the requisite number of Shares due to
              illiquidity in the market for such Shares. Party B will (a) notify
              Party A within one Clearance System Business Day of the Settlement
              Date to that effect and (b) deliver on the Settlement Date such
              number of Shares, if any, as it can deliver on that date. In such
              case, irrespective of the payment measure elected by the parties
              under the Agreement, Loss will be deemed to apply for the purpose
              of determining if any payment will be made in respect of the
              Affected Transaction.

         (b)  In addition to the Termination Events set forth in the Agreement,
              it shall be a Termination Event, with Party A as the sole Affected
              Party and this Transaction the sole Affected Transaction, if
              delivery of Shares by Party B to Party A on the Settlement Date or
              on any Partial Settlement Date would violate any applicable law or
              regulation, including but not limited to Regulation M and Rules
              10b-13, 13e-1 and 13e-4 under the Securities Exchange Act of 1934,
              or Section 2:98 of the Dutch Civil Code. If a violation of the
              kind referred to in the preceding sentence would otherwise
              constitute an Event of Default under the Agreement, the preceding
              sentence shall apply and the violation shall not constitute an
              Event of Default. In addition, irrespective of the payment measure
              elected by the parties under the Agreement, Loss will be deemed to
              apply for the purpose of determining if any payment will be made
              in respect of the Affected Transaction.
