               CHICAGO BRIDGE & IRON COMPANY N.V. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  JUNE 30, 1999
                                 (IN THOUSANDS)


1.   BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements for Chicago Bridge
& Iron Company N.V. and Subsidiaries (the "Company") have been prepared pursuant
to the rules and regulations of the Securities and Exchange Commission. Certain
information and footnote disclosures, normally included in financial statements
prepared in accordance with generally accepted accounting principles, have been
condensed or omitted pursuant to such rules and regulations, although the
Company believes that the disclosures are adequate to make the information
presented not misleading. The accompanying unaudited interim consolidated
financial statements should be read in conjunction with the consolidated
financial statements and notes thereto included in the 1998 Annual Report on
Form 10-K of the Company.

In the opinion of the Company, all adjustments necessary to present fairly the
financial position of the Company and the results of its operations and cash
flows for the period then ended have been included. The results of operations
for such interim periods are not necessarily indicative of the results for the
full year.

2.   SIGNIFICANT ACCOUNTING POLICIES

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133"). SFAS 133 is effective for fiscal years
beginning after June 15, 2000. SFAS 133 requires all derivative instruments be
recorded on the balance sheet at their fair value and that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. The Company has not yet determined the impact
that the adoption of SFAS 133 will have on its earnings or statement of
financial position. However, the Company anticipates that, due to its limited
use of derivative instruments, the adoption of SFAS 133 will not have a
significant effect on its results of operations or its financial position.

3.   LONG-TERM DEBT

The weighted average interest rate on $26,000 of borrowings under the Company's
revolving credit facility was 5.63% at June 30, 1999.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS
                             AND FINANCIAL CONDITION

The following discussion and analysis should be read in conjunction with the
consolidated financial statements and accompanying notes.

RESULTS OF OPERATIONS

For the three months ended June 30, 1999, new business taken was $202 million
compared with $204 million in the year-earlier period. More than 65% of the new
business taken during the quarter was for contracts awarded outside North
America. New contract awards in the quarter included a large low temperature
tank and several large tankage projects in the Europe, Africa, Middle East
(EAME) area, including the Company's first significant project in Egypt in
nearly a decade. During the quarter, new business taken increased 56% in the
EAME area and 25% in North America, but declined 59% in the Asia Pacific (AP)
area and 61% in the Central and South America (CSA) area. For the six months
ended June 30, 1999, new business taken was $395 million compared with $415
million in the first half of 1998. Backlog at June 30, 1999 stood at $534
million, compared with a $508 million backlog at year-end 1998.

Revenues for the second quarter of 1999 were $181.2 million compared with $181.8
million in the second quarter of 1998. Revenues increased in North America and
in the CSA area as a result of work being put in place that follows from last
year's record level of new business taken. The EAME area and the AP area
reported lower revenues in the second quarter, as EAME benefited from
particularly strong revenues in the comparable 1998 period. It is common for the
Company to experience such shifts of revenue among geographic regions given the
changing mix of projects worldwide. Revenues for the first six months of 1999
were $351.9 million compared with $371.7 million for the first half of 1998.
Revenues for the second half of 1999 may be lower than the first half due to the
level and timing of customer releases of new business.

Gross profit for the three months ended June 30, 1999 increased 8% to $18.9
million, or 10.4% of revenues, compared with $17.5 million, or 9.6% of revenues,
in the prior year quarter. The improvement was due primarily to significantly
better results in the CSA area. Continued improvements in project execution have
contributed to better overall operating results. Gross profit for the first half
of 1999 was $36.9 million, or 10.5% of revenues, compared with $34.4 million, or
9.3% of revenues, for the first six months of 1998. The future level of 1999
gross profit is dependent in part upon the volume of work, in particular, the
pace at which new project awards are converted to revenues.

Selling and administrative expenses for the quarter ended June 30, 1999 were
$11.9 million or 6.6% of revenues, matching the prior year quarter. In the first
half of 1999, selling and administrative expenses of $23.9 million matched the
level for the comparable 1998 period.

Other operating income for the quarter ended June 30, 1999 was $0.5 million
compared with $0.3 million for the second quarter of 1998 and consisted of gains
on the sale of property and equipment around the world. The Company anticipates
similar gains in the foreseeable future, as it continues to evaluate and sell
underutilized and older assets.



                                        9
<PAGE>   10

Income from operations for the second quarter of 1999 increased 26% to $7.5
million compared with operating income of $5.9 million for the second quarter of
1998. Operating income was favorably impacted by significantly improved results
in CSA, which more than offset lower income in EAME and North America, both of
which benefited from several large projects in the 1998 period. Income from
operations for the first six months of 1999 was $14.1 million compared with
$11.3 million in the first half of 1998.

Interest expense was $0.8 million for the second quarter of 1999 compared with
$1.0 million in the comparable period of 1998. The decrease was primarily due to
lower debt levels. Long-term debt stood at $26 million as of June 30, 1999, down
from $30 million at the end of the first quarter but up from an unusually low
level of $5 million at year end 1998. Cash and cash equivalents at the end of
the second quarter were $8.4 million. Interest income consisted primarily of
interest earned on cash balances at non-U.S. subsidiaries.

For the six months ended June 30, 1999, income tax expense was $4.0 million, or
an effective income tax rate of 30%, compared with income tax expense of $2.8
million, or an effective income tax rate of 28%, in the comparable period of the
prior year. The increase in the effective tax rate is the result of the
geographic mix of taxable income.

Net income for the three months ended June 30, 1999 was $4.4 million or $0.38
per diluted share, a 19% increase, compared with net income of $3.9 million or
$0.32 per diluted share for the same period in 1998. Net income for the first
six months of 1999 was $8.6 million or $0.75 per diluted share, a 27% increase,
compared with net income of $7.3 million or $0.59 per diluted share for the
first half of 1998.



FINANCIAL CONDITION

For the three months ended June 30, 1999, the Company generated cash from
operations of $12.2 million, reducing cash used from operations to $8.2 million
for the first half of 1999. Capital expenditures were $3.6 million during the
quarter, bringing the year-to-date total to $6.5 million.

The Company continues to be impacted by the Tuban project in Indonesia, where
work remains suspended. At June 30, 1999, the Company's backlog related to this
project was approximately $50 million and the Company and its affiliates had
approximately $35 million of net receivables outstanding. Similar to other major
contractors involved in the project, the Company has received approval to
redeploy certain material purchased for this project in order to reduce its
costs. The Company believes that permanent financing for the project will not be
secured until the political and economic situation in Indonesia improves. While
the Company believes the project is viable and work will ultimately resume, no
assurances can be given that this will happen, or even though the project
resumes, that it will not have an adverse impact on the Company.

Management anticipates that by using cash generated from operations and funds
provided under the Revolving Credit Facility, the Company will be able to meet
its working capital and capital expenditure needs for at least the next 24
months.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company seeks to minimize the risks from currency exchange rate fluctuations
through regular operating and financing activities and, when deemed appropriate,
through its limited use of currency forward contracts. The Company's exposure to
changes in currency exchange rates arises from receivables, payables and firm
commitments from international transactions, as well as intercompany loans used
to finance non-U.S. subsidiaries. The Company does not use financial instruments
for trading or speculative purposes.

Although the Company does not engage in currency speculation, it periodically
uses forward contracts to hedge currency transactions. Gains or losses are
included in income. At June 30, 1999 and December 31, 1998 the Company had
currency exchange contracts of less than one year duration. Outstanding currency
exchange contracts to purchase Canadian dollars represented $609 and $10,034 and
currency exchange contracts to sell British pounds represented $882 and $2,909
at June 30, 1999 and December 31, 1998, respectively. The Company also had
$1,400 and $2,400 of currency exchange contracts to sell Singapore Dollars at
June 30, 1999 and December 31, 1998, respectively and had $1,127 of currency
exchange contracts to sell Dutch Guilders at June 30, 1999.

YEAR 2000

The Company continues to execute its plan to address the effect of Year 2000
issues on its worldwide businesses. The plan consists of two primary phases:
Assessment (consisting of identification, business criticality ranking and
impact analysis, and remediation planning) and Remediation (consisting of
repair, testing, implementation, certification and contingency plans). This plan
involves representatives of the Company from all operational and geographical
areas and encompasses information technology (IT) systems, embedded (non-IT)
systems and suppliers. The Year 2000 team reports to senior management and the
Audit Committee of the Supervisory Board on a quarterly basis.

Assessment has been completed on all of the Company's worldwide IT systems. The
Remediation phase for all critical areas remains on schedule and is expected to
be completed by the end of August 1999. Additional final testing and
certification of certain systems and the customizing of contingency plans is
scheduled to be completed by the end of September 1999.

Assessment of North American non-IT systems is complete, and the Remediation
phase continues and is scheduled for completion by the end of August 1999.
Non-IT systems include building and mechanical systems (such as
telecommunication systems, HVAC and security systems) and fabrication and field
construction equipment. Assessment of non-IT systems outside North America on
building and mechanical systems in facilities currently used by the Company was
completed in June 1999 and the Remediation phase is scheduled to be completed by
the end of August 1999. The Company's assessment and remediation of its
fabrication and field construction equipment throughout the world has been
completed.

Due to the continual change of geographic location and type of projects on which
the Company is executing work, the Company is familiar with reassessing and
reestablishing its supplier chain through the use of alternative sourcing of
materials and services to meet its business needs.



                                       11
<PAGE>   12

The Company has identified key material suppliers and service providers
("suppliers"), and has initiated discussions and mailed correspondence to these
suppliers to survey their state of readiness on Year 2000 issues. Completion of
this assessment is dependent upon their cooperation. Responses have been
received from 98% of the North American inquiries and 94% of the non-North
American inquiries. The Company continues to work to get responses from
suppliers. At this point, it is not possible to predict whether there will be
any significant disruption due to supplier failure to remediate their own Year
2000 issues. The Company, as part of the Remediation phase, has formulated its
contingency plan. This plan includes the Company's continuous communication with
suppliers to assure that they are able to continue to perform without
disruption.

The Company estimates that the cost to remediate its Year 2000 issues is $2.0
million ($1.7 million expense and $0.3 million capitalized for the accelerated
purchase of desktop hardware). As of June 30, 1999, $1.2 million had been
expensed and $0.2 million had been capitalized. The cost estimate excludes the
direct costs of the ongoing J.D. Edwards implementation (which is a Year 2000
compliant system), the costs of which are being capitalized. The decision to
implement this new information system was made independent of the Company's Year
2000 compliance efforts. A portion of the J.D. Edwards system implementation
will enable the Company to meet its Year 2000 remediation need and is scheduled
to be completed by August 31, 1999. Over the next several years the Company will
continue to integrate its other software systems into J.D. Edwards in order to
fully utilize the system's capabilities.

The Company has performed Year 2000 remediation audits of its systems on a
global basis and are scheduled to be completed by the end of October 1999. No
critical issues have been identified during these audits. The Company believes
that the current efforts to address and resolve the issues associated with Year
2000 are adequate. However, the Company cannot guarantee that all Year 2000
issues will be anticipated and corrected, and there can be no assurance that the
systems of any third party on which the Company's systems and operations rely
will be timely converted. It is too soon to determine whether the Company will
experience disruption to transportation, communication, electric power or other
infrastructure systems due to Year 2000 issues that affect the public
infrastructure in the locations where it executes projects. The inability of the
Company, its suppliers or the public infrastructure to effectuate solutions to
their respective Year 2000 issues on a timely and cost effective basis may have
a material adverse effect on the Company.

Because of the uncertainties the Company faces with regard to Year 2000 issues,
it has developed contingency plans to provide for continuation of its critical
operations in spite of possible Year 2000 disruptions. Contingency plans for the
Company's specific global locations are being customized to address the severity
levels of Year 2000 issues that may be encountered. Completion of these plans is
expected by the end of September 1999. If the Company is unsuccessful in
implementing the J.D. Edwards system at remaining locations by the Year 2000,
the cost of implementing the J.D. Edwards contingency plan would not be material
to the Company.

This discussion and analysis contains certain forward-looking statements that
involve a number of risks and uncertainties. Actual events or results may differ
materially from the Company's expectations. In addition to matters described
herein, including the Tuban project and Year 2000 issues, the uncertain timing
of awards and contracts, project cancellation risks, operating risks,



                                       12
<PAGE>   13

risks associated with fixed price contracts, risks associated with percentage of
completion accounting, fluctuating revenues and cash flow, dependence on the
petroleum and petrochemical industries, and competitive conditions, as well as
risk factors listed from time to time in the Company's reports filed with the
Securities and Exchange Commission (including, but not limited to its
Registration Statement on Form S-1 [File No.333-18065], as amended), may affect
the actual results achieved by the Company.

4.        The supervisory board is authorised, provided that the supervisory
          board has been designated by the general meeting as the body
          authorized to issue shares, to issue, at the expense of a reserve of
          the company, with due observance of the provisions of article 31,
          paragraph 3, shares and options to subscribe for new shares, provided
          that such shares and options are issued to employees of the company
          under a valid employee option scheme of the company.
Article 7. Conditions of issuance. Rights of pre-emption.
1.        A resolution for the issuance of shares shall stipulate the price and
          further conditions of issuance.
2.        On the issuance of shares, each shareholder shall have a right of
          pre-emption in proportion to the aggregate nominal value of his
          shares. No pre-emptive rights shall exist with regard to shares issued
          against a contribution other than cash nor with regard to shares
          issued to employees of the company or employees of group companies.
3.        Shareholders shall have a similar right of pre-emption if options are
          granted to subscribe for shares.
4.        The company shall inform the shareholders of the issuance of shares in
          respect of which there is a right of pre-emption, or, as the case may
          be, the granting of options to subscribe for shares in respect of
          which there is a right of pre-emption, as well as the period of time
          during which the right of pre-emption may be exercised, with due
          observance of the applicable provisions of Dutch law.
5.        The right of pre-emption may, subject to due observance of the
          relevant provisions of the law, be limited or excluded by the
          supervisory board provided the supervisory board is designated as the
          authorized body in this respect by resolution of the general meeting
          for a fixed period of time not exceeding five years. Article 6
          paragraph 3 shall apply correspondingly.
Article 8. Payment for shares.
1.        The full nominal amount of each share must be paid in on issue, as
          well as, if a share is subscribed for at a higher price, the balance
          of these amounts.
2.        Payment for a share must be made in cash insofar as no other manner of
          payment has been agreed on. Payment in foreign currency can be made
          only after approval by the company, which approval shall be deemed
          given upon acceptance of foreign currency by the company.
3.        The management board shall be authorised to enter into transactions
          concerning non-monetary contributions on shares, and the other
          transactions referred to in article 94 paragraph 1, Book 2 of the
          Civil Code, without the prior approval of the general meeting.
Article 9. Own shares.
1.        When issuing shares the company shall not be entitled to subscribe for
          its own shares.
2.        The company shall be entitled to acquire its own fully paid up shares
          or depository receipts in respect thereof, provided either no valuable
          consideration is given or provided that:
          a.      the distributable part of the net assets is at least equal
                  to the purchase price; and
          b.      the nominal value of the shares or the depository receipts
                  in respect thereof to be acquired by the company itself,
                  already held by the company or pledged for the benefit of
                  the company, or which are held by a subsidiary, does not
                  exceed one tenth of the issued share capital.


                                       4



<PAGE>   5




3.       The validity of the acquisition shall be determined by the amount of
         the net assets according to the latest adopted balance sheet, decreased
         by the consideration for shares in the company's capital or depository
         receipts in respect thereof and distributions of profits or by the
         charge of any reserve to third parties which have fallen due by the
         company and its subsidiaries after the balance sheet date. If more than
         six months of a financial year have elapsed and the annual accounts
         have not been adopted, any acquisition in conformity with paragraph 2
         shall not be permitted.
4.       An acquisition for valuable consideration shall be permitted only if
         the general meeting has authorized the management board in this respect
         and after approval of the supervisory board. The authorization by the
         general meeting shall be valid for a period not exceeding eighteen
         months. The general meeting shall stipulate in the authorization how
         many shares or depositary receipts in respect thereof may be acquired,
         how they may be acquired, and between what limits the price must be.
5.       An acquisition of shares in contravention of paragraphs 2-4 shall be
         void. Depositary receipts in respect of shares acquired by the company
         in contravention of paragraphs 2-4 shall be transferred to all members
         of the management board by operation of law.
6.       The transfer of shares owned by the company or depositary receipts in
         respect thereof held by the company shall be effected by virtue of a
         resolution of the management board, after approval of the supervisory
         board. The resolution to such transfer shall also stipulate the
         conditions thereof.
7.       No voting rights can be exercised in the general meeting in respect of
         any share belonging to the company or to any subsidiary of the company;
         the same applies to any share in respect of which either the company or
         any subsidiary holds depositary receipts. The beneficiary of a life
         interest in respect of a share held by the company itself or a
         subsidiary company is, however, not excluded from exercising the right
         to vote if the life interest was created before the share was held by
         the company or one of its subsidiaries. The company or its subsidiary
         may not exercise voting rights in respect of shares of which the
         company has a life interest.
8.       In establishing to what extent shareholders exercise voting rights, are
         present or are represented, shares for which no voting rights can be
         exercised shall not be taken into consideration.
9.       The company may take its own shares or depositary receipts in respect
         thereof as pledge only if:
         a.       the shares to be pledged are fully paid up;
         b.       the aggregate nominal value of the shares and depositary
                  receipts in respect thereof to be pledged and already held
                  or held in pledge does not exceed one-tenth of the issued
                  capital, and
         c.       the general meeting has approved the pledge agreement.
10.      Upon the proposal of the management board - which proposal must have
         prior approval from the supervisory board - the general meeting shall
         have the power to decide to cancel shares acquired by the company in
         its own share capital, subject however to the statutory provisions
         relating hereto.

1.       The transfer of shares and the creation and transfer of limited rights
         thereon shall take place in accordance with the provisions of Dutch law
         applicable thereto.
2.       The shareholder shall have the voting rights in respect of the shares
         in which a life interest has been created. However, the voting rights
         shall accrue to the beneficiary of a life interest if it was so
         stipulated at the creation of the life interest. The shareholder who
         holds no voting rights and the beneficiary of a life interest who does
         hold voting rights, shall have the rights which the law attributes to
         holders of depository receipts issued with the company's co-operation.
         The rights referred to in the preceding sentence shall not accrue to
         the beneficiary of the life interest who holds no voting rights.
3.       The shareholder shall have the rights resulting from a share in which a
         life interest has been created relating to the acquisition of newly
         issued shares, such as stock dividends, it being understood that he/she
         shall have to compensate the beneficiary of the life interest for the
         value of these rights insofar as the latter is entitled thereto by
         virtue of his/her life interest.
4.       When shares are pledged, the voting rights cannot be assigned to the
         pledgee. He shall not have the rights which the law attributes to
         holders of depository receipts issued with the company's co-operation.
5.       The company shall not co-operate with the issuance of depository
         receipts in respect of its shares.

         thirds of the votes cast which two thirds of the votes represent more
         than half of the issued share capital.

         represent the company.

         such staff members' titles.
3.       In the event of a conflict of interest between the company and a member

         investigative (other than an action by or in the right of the company)
         by reason of the fact that he is or was a supervisory director, member
         of the management board, officer, employee or agent of the company, or
         is or was serving at the request of the company as a supervisory
         director, member of the management board, officer, director, employee,
         trustee or agent of another company, a partnership, joint venture,
         trust or other enterprise or entity, against all expenses (including
         attorneys' fees), judgements, fines and amounts paid in settlement
         actually and reasonably incurred by


                                       9


<PAGE>   10



         him in connection with such action, suit or proceeding if he acted in
         good faith and in a manner he reasonably believed to be in or not
         opposed to the best interests of the company, and, with respect to any
         criminal action or proceeding, had no reasonable cause to believe his
         conduct was unlawful or outside of his mandate. The termination of any
         action, suit or proceeding by a judgement, order, settlement,
         conviction, or upon a plea of nolo contender or its equivalent, shall
         not, of itself, create a presumption that the person did not act in
         good faith and not in a manner which he reasonably could believe to be
         in or not opposed to the best interest of the company, and, with
         respect to any criminal action or proceeding, had reasonable cause to
         believe that his conduct was unlawful.
2.       The company shall indemnify any person who was or is a party or is
         threatened to be made a party to any threatened, pending or completed
         action or proceeding by or in the right of the company to procure a
         judgement in its favour, by reason of the fact that he is or was a
         supervisory director, member of the management board, officer or agent
         of the company, or is or was serving at the request of the company as
         a supervisory director, member of the management board, officer,
         director, employee, trustee or agent of another company, a
         partnership, joint venture, trust or other enterprise or entity,
         against all expenses (including attorneys' fees) judgements, fines and
         amounts paid in settlement, actually and reasonably incurred by him in
         connection with such action, suit or proceeding if he acted in good
         faith and in a manner he reasonably believed to be in or not opposed
         to the best interests of the company, except that no indemnification
         shall be made in respect of any claim, issue or matter as to which
         such person shall have been adjudged to be liable for gross negligence
         or wilful misconduct in the performance of his duty to the company,
         unless and only to the extent that the court in which such action or
         proceeding was brought or any other court having appropriate
         jurisdiction shall determine upon application that, despite the
         adjudication of liability but in view of all of the circumstances of
         the case, such person is fairly and reasonably entitled to
         indemnification against such expenses which the court in which such
         action or proceeding was brought or such other court having
         appropriate jurisdiction shall deem proper.
3.       To the extent that a supervisory director, member of the management
         board, officer, employee or agent of the company has been successful on
         the merits or otherwise in defense of any action, suits of proceeding,
         referred to in paragraphs 1 and 2, or in defense of any claim, issue or
         matter therein, he shall be indemnified against expenses (including
         attorneys' fees) actually and reasonably incurred by him in connection
         therewith.
4.       Any indemnification by the company referred to in paragraphs 1 and 2
         shall (unless ordered by a court) only be made upon a determination
         that indemnification of the supervisory director, member of the
         management board, officer, director, employee, trustee or agent is
         proper under the circumstances because he had met the applicable
         standard of conduct set forth in paragraph 1 and 2 of this Article 25.
         Such determination shall be made:
         a.       by a majority of  supervisory  directors who are not parties
                  to such action,  suit or proceeding, even though less than
                  a quorum, or;
         b.       if there are no supervisory directors who are not named as
                  parties to such action, suit or proceeding or if the
                  supervisory directors who are not named as parties to such
                  action, suit or proceeding so direct, by independent legal
                  counsel in a written opinion; or



                                       10

         c.       by the general meeting of shareholders.
5.       Expenses incurred in defending a civil or criminal action, suit or
         proceeding may be paid by the company in advance of the final
         disposition of such action, suit or proceeding upon a resolution of the
         supervisory board with respect to the specific case upon receipt of an
         undertaking by or on behalf of the supervisory director, member of the
         management board, officer, director, employee, trustee or agent to
         repay such amount unless it shall ultimately be determined that he is
         entitled to be indemnified by the company as authorized in this
         article.
6.       The indemnification provided for by this article shall not be
         deemed exclusive of any other right to which a person seeking
         indemnification may be entitled under the laws of the Netherlands as
         from time to time amended or under any by-laws, agreement, resolution
         of the general meeting of shareholders or of the disinterested members
         of the supervisory board or otherwise, both as to actions in his
         official capacity and as to actions in another capacity while holding
         such position, and shall continue as to a person who has ceased to be
         a supervisory director, member of the management board, officer,
         director, employee, trustee or agent and shall also inure to the
         benefit of the heirs, executors and administrators of such a person.
7.       The company shall have the power to purchase and maintain insurance on
         behalf of any person who is or was a supervisory director, member of
         the management board, officer, employee or agent of the company, or is
         or was serving at the request of the company as a supervisory director,
         member of the management board, officer, director, employee, trustee or
         agent of another company, a partnership, joint venture, trust or other
         enterprise, or entity, against any liability asserted against him and
         incurred by him in any such capacity or arising out of his capacity as
         such, whether or not the company would have the power to indemnify him
         against such liability under the provisions of this article.
8.       Whenever in this article reference is made to the company, this
         shall include, in addition to the resulting or surviving company also
         any constituent company (including any constituent company of a
         constituent company) absorbed in a consolidation or merger which, if
         its separate existence had continued, would have had the power to
         indemnify its supervisory directors, members of the management board,
         officers, employees and agents, so that any person who is or was a
         supervisory director, member of the management board, officer,
         employee or agent of such constituent company, or is or was serving at
         the request of such constituent company as a supervisory director,
         member of the management board, officer, director, employee, trustee
         or agent of another company, a partnership, joint venture, trust or
         other enterprise or entity, shall stand in the same position under the
         provisions of this article with respect to the resulting or surviving
         company as he would have with respect to such constituent company if
         its separate existence had continued.
9.       No person shall be personally liable to the company or its
         stockholders for monetary damages for breach of fiduciary duty as a
         supervisory director or member of the management board; provided,
         however, that the foregoing shall not eliminate or limit the liability
         of a supervisory director or member of the management board (1) for
         any breach of such individual's duty of loyalty to the company or its
         stockholders, (2) for acts or omissions not in good faith or which
         involve intentional misconduct or a knowing violation of law, (3) for
         any transaction from which the director derived an improper



                                       11


<PAGE>   12


         personal benefit or (4) for personal liability which is imposed by
         Dutch law, as from time to time amended. Any amendment, repeal or
         modification of this Article 25 shall not adversely affect any right
         or protection of any person with respect to any act or omission
         occurring prior to such amendment, repeal or modification.

inspection.
1.       The fiscal year of the company shall be the calendar year.
2.       Annually, and not later than five months after the end of the fiscal

         by reason of special circumstances, this period is extended with a
         maximum extension of six months by the general meeting.
3.       Within the period referred to in paragraph 2, the annual accounts shall
         be deposited at the office of the company for inspection by the
         shareholders. Within this period of time, the management board shall
         also submit the annual report. The statement of the accountant, as
         mentioned in article 29, and the additional information required by
         virtue of the law shall be added to the annual accounts.
4.       The annual accounts shall be signed by all the members of the
         management board; if the signature of one or more of the members is
         lacking, this shall be stated and reasons given.
Article 27. Accountant.
1.       The company shall appoint an accountant to audit the annual accounts.
2.       Such appointment shall be made by the general meeting. This resolution
         of the general meeting shall require the approval of the supervisory
         board. If the general meeting fails to make an appointment, the
         supervisory board shall be competent to do so or, in the absence of the
         supervisory board members or in the event the supervisory board fails
         to do so, the management board shall be competent to do so. The
         appointment of an accountant shall not be limited by virtue of any
         nomination; the appointment may, at all times, be revoked by the
         general meeting or by the supervisory board or management board if
         either of the latter boards has appointed the accountant.
3.       The accountant shall issue a report on his audit examination to the
         supervisory board and the management board.

         and the annual report to the supervisory board.
2.       The annual accounts shall be signed by the members of the supervisory
         board; if the signature of one or more of them is lacking, this shall
         be stated and reasons given.
3.       The supervisory board shall present a report on the annual accounts
         to the general meeting.
Article 29. Adoption.
1.       The company shall ensure that the annual accounts, the annual
         report and the information to be added by virtue of the law are kept
         at its office as of the date on which the annual meeting is convened.
         Shareholders, and beneficiaries of a life interest in shares to whom


                                       12


<PAGE>   13



         the right to vote the shares accrue, may inspect the documents at such
         place and obtain a copy thereof, free of charge.
2.       The general meeting shall adopt the annual accounts. The annual
         accounts may not be adopted in the event that the general meeting has
         been unable to inspect the accountant's declaration referred to in
         article 27, paragraph 4, unless a legal ground is given in the
         information required to be added by law for the lack of the
         accountant's declaration referred to in article 27, paragraph 4.
3.       The unconditional adoption of the annual accounts by the general
         meeting shall serve to constitute a discharge of the management board
         members for their management and for the supervisory board members for
         their supervision insofar as such management and supervision is
         apparent from the annual accounts.
Article 30. Publication.
1.       The company shall publish the annual accounts within eight days
         following the adoption thereof. The publication shall be effected by
         the deposit of a complete copy in the Dutch language or, if such copy
         was not prepared, a copy in the French, German or English language, at
         the offices of the Trade Register in whose district the company has its
         official seat according to these articles of association. The date of
         adoption must be stated on the copy.
2.       If the annual accounts are not adopted within seven months of the
         termination of the fiscal year, in accordance with the legal
         requirements, then the management board shall, without further delay,
         publish the prepared annual accounts in the manner prescribed in
         paragraph 1; it shall be noted on the annual accounts that they have
         not yet been adopted.
3.       In the event that the general meeting shall have extended the period
         for the preparation of the annual accounts in accordance with article
         28 paragraph 2, then the last preceding paragraph shall apply with
         effect from the date falling two months from the termination of such
         period.
4.       A copy of the annual report, produced in the same language or in Dutch,
         shall, together with the additional information required by virtue of
         law, be published at the same time and in the same manner as the annual
         accounts. Insofar as the law permits, the foregoing shall not apply if
         copies of those documents are held at the office of the company for
         inspection by any person and, upon request, full or partial copies
         thereof are supplied at a price not exceeding the cost; the company
         shall make an official return thereof for filing in the Trade Register.
5.       The publication shall be effected with due observance of the
         applicable legal exemptions.
Article 31. Profits. Distribution.
1.       From the profits appearing from the annual accounts as adopted,
         such an amount shall be reserved by the company as shall be determined
         by the management board which resolution requires the approval of the
         supervisory board. The profits remaining thereafter shall be treated
         in accordance with the provisions of the following paragraphs of this
         article.
2.       The profits remaining after the reservation referred to in paragraph 1
         are at the disposal of the general meeting for distribution on the
         shares equally and proportionally and/or for reservation.
3.       A distribution can only take place up to the distributable part of
         the net assets.

<PAGE>   14


4.       Distributions of profits shall take place after adoption of the annual
         accounts from which it shall appear that approval of such accounts has
         been given.
5.       The management board may, subject to due observance of the provisions
         of article 31, paragraph 3, and with the approval of the supervisory
         board resolve to pay an interim dividend in anticipation of the final
         dividends.
6.       On the proposal of the management board, which proposal shall require
         the prior approval of the supervisory board, subject to the due
         observance of the provisions of article 31, paragraph 3, the general
         meeting may resolve to make distributions at the expense of any
         reserve.
7.       The supervisory board or - in case the supervisory board is no longer
         authorised to issue shares in accordance to article 6 - the general
         meeting, may determine to distribute stock dividends.
Article 32. Date on which distributions become payable. Currency.
1.       The date on which  dividends and other payments become payable shall
         be announced in accordance with article 42. V
2.       The management board may resolve to make payments in the currency of
         the country where these payments are made payable.
3.       Any claim of a shareholder for payment shall be barred after five
         years have elapsed.

Article 33. Annual meeting.
1.       Annually, and not later than six months after the end of the fiscal
         year, the annual meeting shall be held.

         points for discussion:
         a.       the annual report;
         b.       adoption of the annual accounts;

         e.       other proposals put forward for discussion and announced with
                  due observance of article 35 by the supervisory board, the
                  management board or by the shareholders and beneficiaries of a
                  life interest to whom the voting right has been granted,
                  representing, in the aggregate, at least one-tenth of the
                  issued capital.
Article 34. Other meetings.
1.       Other general meetings of shareholders shall be held as often as the
         management board or the supervisory board deems such necessary.

         one-tenth of the issued capital, may request the management board to
         convene a general meeting of shareholders, stating the subjects to be
         discussed. If the management board has not convened a meeting within
         four weeks in such a manner that the meeting can be held within six
         weeks after the request has been made, the persons who have made the
         request shall be authorized to convene a meeting themselves.

with, provided such resolutions are adopted unanimously.
Article 37. Place of the meetings.
The general meetings of shareholders shall be held in Amsterdam, Rotterdam, The
Hague or Schiphol Airport (municipality Haarlemmermeer). In meetings held
elsewhere, resolutions can be validly adopted provided the entire issued capital

1.       The general meetings of shareholders shall be presided over by the
         chairman of the supervisory board or, in his absence, by the vice
         chairman of the supervisory board; in the event that the latter is
         also absent, the supervisory board members present shall elect a
         chairman from their midst. The supervisory board may designate another
         person to act as chairman of a general meeting of shareholders.
2.       If the chairman has not been appointed in accordance with paragraph 1,
         the shareholders present at such meeting shall, themselves, choose a
         chairman.
Article 39. Minutes. Records.
1.       Minutes of the proceedings at any general meeting of shareholders shall
         be kept by a secretary to be designated by the chairman. The minutes
         shall be confirmed by the chairman and the secretary and shall be
         signed by them as proof thereof.
2.       The supervisory board, the chairman or the person who has convened the
         meeting may determine that notarial minutes of the proceedings of the
         meeting shall be drawn up. The notarial minutes shall be co-signed by
         the chairman.
3.       The management board shall keep a record of the resolutions made at
         this general meeting. If the management board is not represented at a
         general meeting, the chairman of the meeting shall provide the
         management board with a transcript of the resolutions made as soon as
         possible after the meeting. The records shall be deposited at the
         offices of the company for inspection by the shareholders and the
         holders of depositary receipts. Upon request, each of them shall be
         provided with a copy or an extract of such record at not more than the

         beneficiaries of a life interest who hold voting rights.
Article 40. Meeting rights. Admittance.
1.       Each shareholder entitled to vote and each beneficiary of a life
         interest or pledgee to whom the voting rights accrue shall be entitled
         to attend the general meeting of shareholders, to address the meeting
         and to exercise his voting rights. Where it concerns registered shares,
         the management board must be notified in writing of the intention to
         attend the meeting. Such notice must be received by the management
         board not later than



                                       15


<PAGE>   16



         on the date mentioned in the notice of the meeting. Where it concerns
         bearer shares the share certificates must be lodged not later than on
         the date mentioned in the notice of the meeting, at the place
         mentioned therein.
2.       The right to take part in the meeting in accordance with paragraph 1
         may be exercised by a proxy authorised in writing, provided that the
         power of attorney has been received by the management board not later
         than on the date mentioned in the notice of the meeting.
3.       The date  mentioned in the notice of the meeting,  referred to in
         paragraphs 1 and 2, cannot be prior than the seventh day prior to the
         date of the meeting.
4.       If the voting rights on a share accrue to the beneficiary of a life
         interest or to a pledgee, instead of to the shareholder, the
         shareholder is also authorised to attend the general meeting of
         shareholders and to address the meeting, provided that, where it
         concerns registered shares, the management board has been notified of
         the intention to attend the meeting in accordance with paragraph 1,
         and, where it concerns bearer shares, the lodging as prescribed by
         paragraph 1 has taken place. Paragraph 2 applies accordingly.

6.       Each person entitled to vote or his proxy shall sign the attendance
         list.
7.       The members of the supervisory board and of the management board shall,
         as such, have the right to advise the general meeting of shareholders.
8.       The chairman shall decide whether persons other than those who shall be
         admitted in accordance with the above provisions of this article shall
         be admitted to the meeting.
Article 41. Votes.
1.       Insofar as no greater majority is prescribed by law or these articles
         of association, all resolutions of the general meeting shall be adopted
         by a majority of the votes cast.
2.       If, in an election of persons, a majority is not obtained, a second
         vote shall be taken. If, again, a majority is not obtained, further
         votes shall be taken until either one person obtains the absolute
         majority or the election is between two persons who have received an
         equal number of votes. In the event of a further election (not
         including the second free vote), the election shall be between the
         persons who participated in the preceding election, with the exception
         of the person who received the smallest number of votes in that
         preceding election. If, in that preceding election, more than one
         person received the smallest number of votes, it shall be decided by
         lot who of these persons shall no longer participate in the new
         election. If the votes are equal in the election between the two, it
         shall be decided by lot who is to be chosen. If there is a tie vote in
         a vote for the election of persons out of a binding list of nominees,
         the first person on that list shall be elected.
3.       If there is a tie vote on a matter other than a vote for the election
         of persons, the proposal shall be rejected.
4.       Votes need not be held in writing. The chairman is, however, entitled
         to decide that a vote shall be by secret ballot. If the vote concerns
         an election of persons, any person present at the meeting and entitled
         to vote can also demand a vote by a secret ballot.
5.       Abstentions and invalid votes shall not be counted as votes that have
         been cast.
6.       Voting by acclamation shall be allowed if none of the persons present
         and entitled to vote objects to it.
7.       The  chairman's  decision at the meeting  about the outcome of a vote
         shall be final and conclusive. The same shall apply to the contents of
         an adopted resolution regarding the voting on an unwritten proposal.
         If, however, the correctness of that decision is



                                       16



<PAGE>   17

         challenged immediately after its pronouncement, a new vote shall be
         taken if either the majority of the persons present and entitled to
         vote so requests, or, if the original voting was taken by roll call or
         in writing, any person present and entitled to vote so requests. As a
         result of the new vote, the original vote shall have no legal
         consequence and shall be cancelled.

Chapter X.
Convocation and notification.
Article 42.
1.       All announcements for the general meetings of shareholders, all
         notifications concerning dividend and other payments and all other

Mr. Robert H. Wolfe
732 Fairfield Court
Westmont, Illinois 60559

                      CHANGE OF CONTROL SEVERANCE AGREEMENT

Dear Mr. Wolfe:

          Chicago Bridge & Iron Company, a Delaware corporation, (the "Company")
is a wholly-owned subsidiary of Chicago Bridge & Iron Company N.V., a
Netherlands corporation (the "Holding Corporation"). The Company recognizes that
members of senior management may become concerned about the effect of a Change
of Control (as defined below) on their job and financial security. The Company
considers the maintenance of a sound and vital management to be essential to
protecting and enhancing the best interests of the Company and the Holding
Corporation. Accordingly, the Board of Directors of the Company has determined
that the Company should enter into this agreement (your "Agreement") to provide
you with severance benefits in the event your employment with the Company
(including any subsidiary of the Company by which you are then employed)
terminates following a Change of Control under certain circumstances.

          The purpose of entering into this Agreement is to induce you to remain
in the employ of the Company pending and after any Change of Control. Therefore,
in consideration of your continued employment with the Company under these
circumstances, the Company and you agree as follows:

          1.      Termination Benefits.

                  (a) Basic Benefits. In the event your employment with the
Company and any subsidiary of the Company terminates by reason of a Qualifying
Termination within two years after a Change of Control, you shall receive,
within thirty days after your employment terminates, a lump sum amount equal to
Seven Hundred Fifty Thousand Dollars ($750,000.00). In addition, if your
employment with the Company and any subsidiary by which you are employed is
terminated by the Company or any such subsidiary for any reason (other than your
willful misconduct or gross negligence in the performance of your duties as an
employee which results in a material detriment to either the Company or the
Holding Corporation) within six months prior to the occurrence of a Change of
Control, you shall be paid the lump sum referred to in the immediately preceding
sentence, minus the gross amount of any severance benefits otherwise paid to
you, within ten days following such Change of Control.

                  (b) Outplacement. In the event of a Qualifying Termination (or
a termination of your employment prior to a Change of Control with respect to
which you are entitled to receive a payment under Section 1(a) of this
Agreement), the Company agrees that, upon a written request from you, it will
engage on your behalf an outplacement or similar firm of your choice to provide
you with customary services and support in seeking other appropriate employment.

                  (c) Certain Further Payments.

                      (i) Additional Payments in Respect of Excise Taxes. In the
event that any amount or benefit paid or distributed to you pursuant to this
Agreement, taken together with any amounts or benefits otherwise paid or
distributed to you (the "Covered Payments"), are or become subject to the tax
(the "Excise Tax") imposed under Section 4999 of the Internal Revenue Code of
1986, as amended (the "Code"), or any similar tax that may hereafter be imposed,
the Company shall pay you, at the same time as it pays the severance benefit
described above, an additional amount (the "Tax Reimbursement Payment") such
that the net amount retained by you with respect to such Covered Payments, after
deduction of any Excise Tax on the Covered Payments and any Federal, state and
local income or employment tax and Excise Tax on the Tax Reimbursement Payment
provided for by this Section 1(b), but before deduction for any Federal, state
or local income or employment tax withholding on such Covered Payments, shall be
equal to the amount of the Covered Payments.

                      (ii) Calculation of the Excise Tax. For purposes of
determining whether any of the Covered Payments will be subject to the Excise
Tax and the amount of such Excise Tax,

                           (A) all "parachute payments" in excess of the "base
                  amount" (as defined under Section 280G(b)(3)) of the Code)
                  shall be treated as subject to the Excise Tax, unless, and
                  except to the extent that, in the good faith judgment of the
                  Company's independent certified public accountants appointed
                  prior to the Change of Control or tax counsel selected by such
                  Accountants (the "Accountants"), the Company has a reasonable
                  basis to conclude that such Covered Payments (in whole or in
                  part) represent reasonable compensation for personal services
                  actually rendered (within the meaning of Section 280G(b)(4)(B)
                  of the Code) in excess of the "base amount," or such
                  "parachute payments" are otherwise not subject to such Excise
                  Tax, and


<PAGE>   3

March 4, 1999


                           (B) the value of any non-cash benefits or any
                  deferred payment or benefit shall be determined by the
                  Accountants in accordance with the principles of Section 280G
                  of the Code.

                      (iii) Calculation of the Tax Reimbursement Payment. For
purposes of determining the amount of the Tax Reimbursement Payment, you shall
be deemed to pay:

                           (A) Federal income taxes at the highest applicable
                  marginal rate of Federal income taxation for the calendar year
                  in which the Tax Reimbursement Payment is to be made, and

                           (B) any applicable state and local income taxes at
                  the highest applicable marginal rate of taxation for the
                  calendar year in which the Tax Reimbursement Payment is to be
                  made, net of the maximum reduction in Federal income taxes
                  which could be obtained from the deduction of such state or
                  local taxes if paid in such year.

                  (d) Adjustments to Tax Reimbursement Payment. In the event
that the Excise Tax is subsequently determined by the Accountants or pursuant to
any proceeding or negotiations with the Internal Revenue Service to be less than
the amount taken into account hereunder in calculating the Tax Reimbursement
Payment made, you shall repay to the Company, at the time that the amount of
such reduction in the Excise Tax is finally determined, the portion of such
prior Tax Reimbursement Payment that would not have been paid if such Excise Tax
had been applied in initially calculating such Tax Reimbursement Payment, plus
interest on the amount of such repayment at the rate provided in Section
1274(b)(2)(B) of the Code. Notwithstanding the foregoing, in the event any
portion of the Tax Reimbursement Payment to be refunded to the Company has been
paid to any Federal, state or local tax authority, repayment thereof shall not
be required until actual refund or credit of such portion has been made to you.
You and the Company shall mutually agree upon the course of action to be pursued
if your good faith claim for refund or credit is denied, provided that the
Company shall bear the cost of any expenses incurred which are related to
pursuing any recovery of any amount paid in respect of the Excise Tax.

                  In the event that the Excise Tax is later determined by the
Accountants or pursuant to any proceeding or negotiations with the Internal
Revenue Service to exceed the amount taken into account hereunder at the time
the Tax Reimbursement Payment is made (including, but not limited to, by reason
of any payment the existence or amount of which cannot be determined at the time
of the Tax Reimbursement Payment), the Company shall make an additional Tax
Reimbursement Payment in respect of such excess (plus any interest or penalty
payable with respect to such excess) at the time that the amount of such excess
is finally determined.

                  subsidiary of the Holding Corporation or the Company, becomes
                  the "beneficial owner" (as such term is used in Section 13 of
                  the Exchange Act) of 25% or more of the total voting power of
                  the Company's or the Holding Corporation's outstanding

                  business combination of the Company or the Holding Corporation
                  with or into another company pursuant to which the
                  stockholders of the Company or the Holding Corporation, as the
                  case may be, do not own, immediately after the transaction,

                  the Board of Directors of the Company or the Holding
                  Corporation, as the case may be, cease for any reason to
                  constitute at least a majority thereof; provided that any new
                  director who is elected to, or nominated for election to, the
                  Board of Directors with the approval of at least 75% of the
                  directors then still in office who were directors at the
                  beginning of the period shall be treated as though having been
                  a director at the beginning of such period.

employment with the Company and any of its subsidiaries by which you are
employed (i) by the Company or any such subsidiary for any reason other than

                  Control or you are required in the performance of your duties
                  to travel to an extent substantially more burdensome than your
                  travel obligations immediately prior to such Change of
                  Control; or

                                    (D) the letter of credit or escrow referred

Section 3.1(a), the Company shall procure and maintain in force until at least

with the Company and any subsidiary of the Company by which you are employed
terminates following a Change of Control, the amounts payable to you hereunder
and any vested amounts or benefits owing to you under the Company's otherwise

benefits referred to in the immediately preceding sentence constitute full
settlement of any claim under law or in equity that you might otherwise assert
against the Company or any of its subsidiaries on account of such termination.

competent jurisdiction to be void or unenforceable, the same shall in no way
affect any other provision of this Agreement or the validity or enforceability

1986, as amended (the "Code"), or any similar tax that may hereafter be imposed,
the Company shall pay you, at the same time as it pays the severance benefit
described above, an additional amount (the "Tax Reimbursement Payment") such
that the net amount retained by you with respect to such Covered Payments, after
deduction of any Excise Tax on the Covered Payments and any Federal, state and
local income or employment tax and Excise Tax on the Tax Reimbursement Payment
provided for by this Section 1(b), but before deduction for any Federal, state
or local income or employment tax withholding on such Covered Payments, shall be
equal to the amount of the Covered Payments.

                           (ii) Calculation of the Excise Tax. For purposes of
determining whether any of the Covered Payments will be subject to the Excise
Tax and the amount of such Excise Tax,

                                    (A) all "parachute payments" in excess of
                  the "base amount" (as defined under Section 280G(b)(3)) of the
                  Code) shall be treated as subject to the Excise Tax, unless,
                  and except to the extent that, in the good faith judgment of
                  the Company's independent certified public accountants
                  appointed prior to the Change of Control or tax counsel
                  selected by such Accountants (the "Accountants"), the Company
                  has a reasonable basis to conclude that such Covered Payments
                  (in whole or in part) represent reasonable compensation for
                  personal services actually rendered (within the meaning of
                  Section 280G(b)(4)(B) of the Code) in excess of the "base
                  amount," or such "parachute payments" are otherwise not
                  subject to such Excise Tax, and

                                    (B) the value of any non-cash benefits or
                  any deferred payment or benefit shall be determined by the
                  Accountants in accordance with the principles of Section 280G
                  of the Code.

                           (iii) Calculation of the Tax Reimbursement Payment.
For purposes of determining the amount of the Tax Reimbursement Payment, you
shall be deemed to pay:

                                    (A) Federal income taxes at the highest
                  applicable marginal rate of Federal income taxation for the
                  calendar year in which the Tax Reimbursement Payment is to be
                  made, and

                                    (B) any applicable state and local income
                  taxes at the highest applicable marginal rate of taxation for
                  the calendar year in which the Tax Reimbursement Payment is to
                  be made, net of the maximum reduction in Federal income taxes
                  which could be obtained from the deduction of such state or
                  local taxes if paid in such year.

                  (d) Adjustments to Tax Reimbursement Payment. In the event
that the Excise Tax is subsequently determined by the Accountants or pursuant to
any proceeding or negotiations with the Internal Revenue Service to be less than
the amount taken into account hereunder in calculating the Tax Reimbursement
Payment made, you shall repay to the Company, at the time that the amount of
such reduction in the Excise Tax is finally determined, the portion of such
prior Tax Reimbursement Payment that would not have been paid if such Excise Tax
had been applied in initially calculating such Tax Reimbursement Payment, plus
interest on the amount of such repayment at the rate provided in Section
1274(b)(2)(B) of the Code. Notwithstanding the foregoing, in the event any
portion of the Tax Reimbursement Payment to be refunded to the Company has been
paid to any Federal, state or local tax authority, repayment thereof shall not
be required until actual refund or credit of such portion has been made to you.
You and the Company shall mutually agree upon the course of action to be pursued
if your good faith claim for refund or credit is denied, provided that the
Company shall bear the cost of any expenses incurred which are related to
pursuing any recovery of any amount paid in respect of the Excise Tax.

                  In the event that the Excise Tax is later determined by the
Accountants or pursuant to any proceeding or negotiations with the Internal
Revenue Service to exceed the amount taken into account hereunder at the time
the Tax Reimbursement Payment is made (including, but not limited to, by reason
of any payment the existence or amount of which cannot be determined at the time
of the Tax Reimbursement Payment), the Company shall make an additional Tax
Reimbursement Payment in respect of such excess (plus any interest or penalty
payable with respect to such excess) at the time that the amount of such excess
is finally determined.

                  the Board of Directors of the Company or the Holding
                  Corporation, as the case may be, cease for any reason to

                  Control or you are required in the performance of your duties
                  to travel to an extent substantially more burdensome than your
                  travel obligations immediately prior to such Change of
                  Control; or

                                    (D) the letter of credit or escrow referred

duties of your position for a period of at least 180 days on account of any
physical or mental impairment, or (iii) your voluntary retirement at or after

                  (b) Letter of Credit: Escrow. To secure its obligations under
Section 3.1(a), the Company shall procure and maintain in force until at least
one year after your termination of employment a letter of credit and an escrow
in favor of you (together with other senior management executives similarly

thereof and having a combined capital and surplus of not less than one hundred
million dollars ($100,000,000), shall be in the aggregate amount of two million

the payments provided for in this Agreement and otherwise to perform its
obligations hereunder shall not be affected by any circumstances, including,
without limitation, any set-off, counterclaim, recoupment, defense or other
right which the Company may have against you or others whether by reason of your
subsequent employment or otherwise. You shall not be obligated to mitigate any
damages you incur by reason of any Qualifying Termination and the amounts
payable hereunder shall not be reduced by any amounts received by you as a
result of your employment or self-employment following your termination
hereunder.

                  (d) Entire Obligation of Company. In the event your employment
with the Company and any subsidiary of the Company by which you are employed
terminates following a Change of Control, the amounts payable to you hereunder
and any vested amounts or benefits owing to you under the Company's otherwise
applicable employee benefit plans and programs and any accrued vacation pay not
yet paid, shall constitute the entire obligation of the Company and its
affiliates to you. Payment or other satisfaction thereof shall be contingent
upon your execution of a release in favor of the Company substantially in the
form of that attached hereto as Exhibit C, stating that the payments and other
benefits referred to in the immediately preceding sentence constitute full
settlement of any claim under law or in equity that you might otherwise assert
against the Company or any of its subsidiaries on account of such termination.

affect any other provision of this Agreement or the validity or enforceability
of this Agreement.

                  (i) Waiver. No provision of this Agreement may be modified,
waived or discharged unless such modification, waiver or discharge is agreed to
in a writing signed by you and such officer as may be specifically designated by
the Board of Directors of the Company or a duly authorized Committee thereof. No
waiver by either party hereto at any time of any breach by the other party
hereto of any condition or provision of this Agreement to be performed by such
other party shall be deemed a waiver of any other condition or provision at any
time.

                  (j) Entire Agreement. This Agreement contains the entire
understanding among the parties hereto with respect to the subject matter

Mr. Robert B. Jordan
2319 Fleetwood Court
Naperville, Illinois 60565

                      CHANGE OF CONTROL SEVERANCE AGREEMENT

Dear Mr. Jordan:

          Chicago Bridge & Iron Company, a Delaware corporation, (the "Company")
is a wholly-owned subsidiary of Chicago Bridge & Iron Company N.V., a
Netherlands corporation (the "Holding Corporation"). The Company recognizes that
members of senior management may become concerned about the effect of a Change
of Control (as defined below) on their job and financial security. The Company
considers the maintenance of a sound and vital management to be essential to
protecting and enhancing the best interests of the Company and the Holding
Corporation. Accordingly, the Board of Directors of the Company has determined
that the Company should enter into this agreement (your "Agreement") to provide
you with severance benefits in the event your employment with the Company
(including any subsidiary of the Company by which you are then employed)
terminates following a Change of Control under certain circumstances.

          The purpose of entering into this Agreement is to induce you to remain
in the employ of the Company pending and after any Change of Control. Therefore,
in consideration of your continued employment with the Company under these
circumstances, the Company and you agree as follows:

          1.      Termination Benefits.

                  (a) Basic Benefits. In the event your employment with the
Company and any subsidiary of the Company terminates by reason of a Qualifying
Termination within two years after a Change of Control, you shall receive,
within thirty days after your employment terminates, a lump sum amount equal to
One Million Dollars ($1,000,000.00). In addition, if your employment with the
Company and any subsidiary by which you are employed is terminated by the
Company or any such subsidiary for any reason (other than your willful
misconduct or gross negligence in the performance of your duties as an employee
which results in a material detriment to either the Company or the Holding
Corporation) within six months prior to the occurrence of a Change of Control,
you shall be paid the lump sum referred to in the immediately preceding
sentence, minus the gross amount of any severance benefits otherwise paid to
you, within ten days following such Change of Control.

March 4, 1999



                  (b) Outplacement. In the event of a Qualifying Termination (or
a termination of your employment prior to a Change of Control with respect to
which you are entitled to receive a payment under Section 1(a) of this
Agreement), the Company agrees that, upon a written request from you, it will
engage on your behalf an outplacement or similar firm of your choice to provide
you with customary services and support in seeking other appropriate employment.

                  (c) Certain Further Payments.

                           (i) Additional Payments in Respect of Excise Taxes.
In the event that any amount or benefit paid or distributed to you pursuant to
this Agreement, taken together with any amounts or benefits otherwise paid or
distributed to you (the "Covered Payments"), are or become subject to the tax
(the "Excise Tax") imposed under Section 4999 of the Internal Revenue Code of
1986, as amended (the "Code"), or any similar tax that may hereafter be imposed,
the Company shall pay you, at the same time as it pays the severance benefit
described above, an additional amount (the "Tax Reimbursement Payment") such
that the net amount retained by you with respect to such Covered Payments, after
deduction of any Excise Tax on the Covered Payments and any Federal, state and
local income or employment tax and Excise Tax on the Tax Reimbursement Payment
provided for by this Section 1(b), but before deduction for any Federal, state
or local income or employment tax withholding on such Covered Payments, shall be
equal to the amount of the Covered Payments.

                           (ii) Calculation of the Excise Tax. For purposes of
determining whether any of the Covered Payments will be subject to the Excise
Tax and the amount of such Excise Tax,

                                    (A) all "parachute payments" in excess of
                  the "base amount" (as defined under Section 280G(b)(3)) of the
                  Code) shall be treated as subject to the Excise Tax, unless,
                  and except to the extent that, in the good faith judgment of
                  the Company's independent certified public accountants
                  appointed prior to the Change of Control or tax counsel
                  selected by such Accountants (the "Accountants"), the Company
                  has a reasonable basis to conclude that such Covered Payments
                  (in whole or in part) represent reasonable compensation for
                  personal services actually rendered (within the meaning of
                  Section 280G(b)(4)(B) of the Code) in excess of the "base
                  amount," or such "parachute payments" are otherwise not
                  subject to such Excise Tax, and


<PAGE>   19

March 4, 1999


                                    (B) the value of any non-cash benefits or
                  any deferred payment or benefit shall be determined by the
                  Accountants in accordance with the principles of Section 280G
                  of the Code.

                           (iii) Calculation of the Tax Reimbursement Payment.
For purposes of determining the amount of the Tax Reimbursement Payment, you
shall be deemed to pay:

                                    (A) Federal income taxes at the highest
                  applicable marginal rate of Federal income taxation for the
                  calendar year in which the Tax Reimbursement Payment is to be
                  made, and

                                    (B) any applicable state and local income
                  taxes at the highest applicable marginal rate of taxation for
                  the calendar year in which the Tax Reimbursement Payment is to
                  be made, net of the maximum reduction in Federal income taxes
                  which could be obtained from the deduction of such state or
                  local taxes if paid in such year.

                  (d) Adjustments to Tax Reimbursement Payment. In the event
that the Excise Tax is subsequently determined by the Accountants or pursuant to
any proceeding or negotiations with the Internal Revenue Service to be less than
the amount taken into account hereunder in calculating the Tax Reimbursement
Payment made, you shall repay to the Company, at the time that the amount of
such reduction in the Excise Tax is finally determined, the portion of such
prior Tax Reimbursement Payment that would not have been paid if such Excise Tax
had been applied in initially calculating such Tax Reimbursement Payment, plus
interest on the amount of such repayment at the rate provided in Section
1274(b)(2)(B) of the Code. Notwithstanding the foregoing, in the event any
portion of the Tax Reimbursement Payment to be refunded to the Company has been
paid to any Federal, state or local tax authority, repayment thereof shall not
be required until actual refund or credit of such portion has been made to you.
You and the Company shall mutually agree upon the course of action to be pursued
if your good faith claim for refund or credit is denied, provided that the
Company shall bear the cost of any expenses incurred which are related to
pursuing any recovery of any amount paid in respect of the Excise Tax.

                  In the event that the Excise Tax is later determined by the
Accountants or pursuant to any proceeding or negotiations with the Internal
Revenue Service to exceed the amount taken into account hereunder at the time
the Tax Reimbursement Payment is made (including, but not limited to, by reason
of any payment the existence or amount of which cannot be determined at the time
of the Tax Reimbursement Payment), the Company shall make an additional Tax
Reimbursement Payment in respect of such excess (plus any interest or penalty
payable with respect to such excess) at the time that the amount of such excess
is finally determined.

Mr. Stephen M. Duffy
15117 Ginger Creek Lane
Orland Park, Illinois 60467

                      CHANGE OF CONTROL SEVERANCE AGREEMENT

Dear Mr. Duffy:

          Chicago Bridge & Iron Company, a Delaware corporation, (the "Company")
is a wholly-owned subsidiary of Chicago Bridge & Iron Company N.V., a
Netherlands corporation (the "Holding Corporation"). The Company recognizes that
members of senior management may become concerned about the effect of a Change
of Control (as defined below) on their job and financial security. The Company
considers the maintenance of a sound and vital management to be essential to
protecting and enhancing the best interests of the Company and the Holding
Corporation. Accordingly, the Board of Directors of the Company has determined
that the Company should enter into this agreement (your "Agreement") to provide
you with severance benefits in the event your employment with the Company
(including any subsidiary of the Company by which you are then employed)
terminates following a Change of Control under certain circumstances.

          The purpose of entering into this Agreement is to induce you to remain
in the employ of the Company pending and after any Change of Control. Therefore,
in consideration of your continued employment with the Company under these
circumstances, the Company and you agree as follows:

          1.      Termination Benefits.

                  (a) Basic Benefits. In the event your employment with the
Company and any subsidiary of the Company terminates by reason of a Qualifying
Termination within two years after a Change of Control, you shall receive,
within thirty days after your employment terminates, a lump sum amount equal to
Two Hundred Forty Thousand Dollars ($240,000.00). In addition, if your
employment with the Company and any subsidiary by which you are employed is
terminated by the Company or any such subsidiary for any reason (other than your
willful misconduct or gross negligence in the performance of your duties as an
employee which results in a material detriment to either the Company or the
Holding Corporation) within six months prior to the occurrence of a Change of
Control, you shall be paid the lump sum referred to in the immediately preceding
sentence, minus the gross amount of any severance benefits otherwise paid to
you, within ten days following such Change of Control.

                  (b) Outplacement. In the event of a Qualifying Termination (or
a termination of your employment prior to a Change of Control with respect to
which you are entitled to receive a payment under Section 1(a) of this
Agreement), the Company agrees that, upon a written request from you, it will
engage on your behalf an outplacement or similar firm of your choice to provide
you with customary services and support in seeking other appropriate employment.

                  (c) Certain Further Payments.

                           (i) Additional Payments in Respect of Excise Taxes.
In the event that any amount or benefit paid or distributed to you pursuant to
this Agreement, taken together with any amounts or benefits otherwise paid or
distributed to you (the "Covered Payments"), are or become subject to the tax
(the "Excise Tax") imposed under Section 4999 of the Internal Revenue Code of
1986, as amended (the "Code"), or any similar tax that may hereafter be imposed,
the Company shall pay you, at the same time as it pays the severance benefit
described above, an additional amount (the "Tax Reimbursement Payment") such
that the net amount retained by you with respect to such Covered Payments, after
deduction of any Excise Tax on the Covered Payments and any Federal, state and
local income or employment tax and Excise Tax on the Tax Reimbursement Payment
provided for by this Section 1(b), but before deduction for any Federal, state
or local income or employment tax withholding on such Covered Payments, shall be
equal to the amount of the Covered Payments.

                           (ii) Calculation of the Excise Tax. For purposes of
determining whether any of the Covered Payments will be subject to the Excise
Tax and the amount of such Excise Tax,

                                    (A) all "parachute payments" in excess of
                  the "base amount" (as defined under Section 280G(b)(3)) of the
                  Code) shall be treated as subject to the Excise Tax, unless,
                  and except to the extent that, in the good faith judgment of
                  the Company's independent certified public accountants
                  appointed prior to the Change of Control or tax counsel
                  selected by such Accountants (the "Accountants"), the Company
                  has a reasonable basis to conclude that such Covered Payments
                  (in whole or in part) represent reasonable compensation for
                  personal services actually rendered (within the meaning of
                  Section 280G(b)(4)(B) of the Code) in excess of the "base
                  amount," or such "parachute payments" are otherwise not
                  subject to such Excise Tax, and


<PAGE>   27

March 4, 1999


                                    (B) the value of any non-cash benefits or
                  any deferred payment or benefit shall be determined by the
                  Accountants in accordance with the principles of Section 280G
                  of the Code.

                           (iii) Calculation of the Tax Reimbursement Payment.
For purposes of determining the amount of the Tax Reimbursement Payment, you
shall be deemed to pay:

                                    (A) Federal income taxes at the highest
                  applicable marginal rate of Federal income taxation for the
                  calendar year in which the Tax Reimbursement Payment is to be
                  made, and

                                    (B) any applicable state and local income
                  taxes at the highest applicable marginal rate of taxation for
                  the calendar year in which the Tax Reimbursement Payment is to
                  be made, net of the maximum reduction in Federal income taxes
                  which could be obtained from the deduction of such state or
                  local taxes if paid in such year.

                  (d) Adjustments to Tax Reimbursement Payment. In the event
that the Excise Tax is subsequently determined by the Accountants or pursuant to
any proceeding or negotiations with the Internal Revenue Service to be less than
the amount taken into account hereunder in calculating the Tax Reimbursement
Payment made, you shall repay to the Company, at the time that the amount of
such reduction in the Excise Tax is finally determined, the portion of such
prior Tax Reimbursement Payment that would not have been paid if such Excise Tax
had been applied in initially calculating such Tax Reimbursement Payment, plus
interest on the amount of such repayment at the rate provided in Section
1274(b)(2)(B) of the Code. Notwithstanding the foregoing, in the event any
portion of the Tax Reimbursement Payment to be refunded to the Company has been
paid to any Federal, state or local tax authority, repayment thereof shall not
be required until actual refund or credit of such portion has been made to you.
You and the Company shall mutually agree upon the course of action to be pursued
if your good faith claim for refund or credit is denied, provided that the
Company shall bear the cost of any expenses incurred which are related to
pursuing any recovery of any amount paid in respect of the Excise Tax.

                  In the event that the Excise Tax is later determined by the
Accountants or pursuant to any proceeding or negotiations with the Internal
Revenue Service to exceed the amount taken into account hereunder at the time
the Tax Reimbursement Payment is made (including, but not limited to, by reason
of any payment the existence or amount of which cannot be determined at the time
of the Tax Reimbursement Payment), the Company shall make an additional Tax
Reimbursement Payment in respect of such excess (plus any interest or penalty
payable with respect to such excess) at the time that the amount of such excess
is finally determined.

without limitation, any set-off, counterclaim, recoupment, defense or other
right which the Company may have against you or others whether by reason of your
subsequent employment or otherwise. You shall not be obligated to mitigate any

terminates following a Change of Control, the amounts payable to you hereunder
and any vested amounts or benefits owing to you under the Company's otherwise

Mr. Stephen P. Crain
1507 Grommon Road
Naperville, Illinois 60565

                      CHANGE OF CONTROL SEVERANCE AGREEMENT

Dear Mr. Crain:

          Chicago Bridge & Iron Company, a Delaware corporation, (the "Company")
is a wholly-owned subsidiary of Chicago Bridge & Iron Company N.V., a
Netherlands corporation (the "Holding Corporation"). The Company recognizes that
members of senior management may become concerned about the effect of a Change
of Control (as defined below) on their job and financial security. The Company
considers the maintenance of a sound and vital management to be essential to
protecting and enhancing the best interests of the Company and the Holding
Corporation. Accordingly, the Board of Directors of the Company has determined
that the Company should enter into this agreement (your "Agreement") to provide
you with severance benefits in the event your employment with the Company
(including any subsidiary of the Company by which you are then employed)
terminates following a Change of Control under certain circumstances.

          The purpose of entering into this Agreement is to induce you to remain
in the employ of the Company pending and after any Change of Control. Therefore,
in consideration of your continued employment with the Company under these
circumstances, the Company and you agree as follows:

          1.      Termination Benefits.

                  (a) Basic Benefits. In the event your employment with the
Company and any subsidiary of the Company terminates by reason of a Qualifying
Termination within two years after a Change of Control, you shall receive,
within thirty days after your employment terminates, a lump sum amount equal to
Seven Hundred Fifty Thousand Dollars ($750,000.00). In addition, if your
employment with the Company and any subsidiary by which you are employed is
terminated by the Company or any such subsidiary for any reason (other than your
willful misconduct or gross negligence in the performance of your duties as an
employee which results in a material detriment to either the Company or the
Holding Corporation) within six months prior to the occurrence of a Change of
Control, you shall be paid the lump sum referred to in the immediately preceding
sentence, minus the gross amount of any severance benefits otherwise paid to
you, within ten days following such Change of Control.

March 4, 1999



                  (b) Outplacement. In the event of a Qualifying Termination (or
a termination of your employment prior to a Change of Control with respect to
which you are entitled to receive a payment under Section 1(a) of this
Agreement), the Company agrees that, upon a written request from you, it will
engage on your behalf an outplacement or similar firm of your choice to provide
you with customary services and support in seeking other appropriate employment.

                  (c) Certain Further Payments.

                           (i) Additional Payments in Respect of Excise Taxes.
In the event that any amount or benefit paid or distributed to you pursuant to
this Agreement, taken together with any amounts or benefits otherwise paid or
distributed to you (the "Covered Payments"), are or become subject to the tax
(the "Excise Tax") imposed under Section 4999 of the Internal Revenue Code of
1986, as amended (the "Code"), or any similar tax that may hereafter be imposed,
the Company shall pay you, at the same time as it pays the severance benefit
described above, an additional amount (the "Tax Reimbursement Payment") such
that the net amount retained by you with respect to such Covered Payments, after
deduction of any Excise Tax on the Covered Payments and any Federal, state and
local income or employment tax and Excise Tax on the Tax Reimbursement Payment
provided for by this Section 1(b), but before deduction for any Federal, state
or local income or employment tax withholding on such Covered Payments, shall be
equal to the amount of the Covered Payments.

                           (ii) Calculation of the Excise Tax. For purposes of
determining whether any of the Covered Payments will be subject to the Excise
Tax and the amount of such Excise Tax,

                                    (A) all "parachute payments" in excess of
                  the "base amount" (as defined under Section 280G(b)(3)) of the
                  Code) shall be treated as subject to the Excise Tax, unless,
                  and except to the extent that, in the good faith judgment of
                  the Company's independent certified public accountants
                  appointed prior to the Change of Control or tax counsel
                  selected by such Accountants (the "Accountants"), the Company
                  has a reasonable basis to conclude that such Covered Payments
                  (in whole or in part) represent reasonable compensation for
                  personal services actually rendered (within the meaning of
                  Section 280G(b)(4)(B) of the Code) in excess of the "base
                  amount," or such "parachute payments" are otherwise not
                  subject to such Excise Tax, and


<PAGE>   35

March 4, 1999


                                    (B) the value of any non-cash benefits or
                  any deferred payment or benefit shall be determined by the
                  Accountants in accordance with the principles of Section 280G
                  of the Code.

                           (iii) Calculation of the Tax Reimbursement Payment.
For purposes of determining the amount of the Tax Reimbursement Payment, you
shall be deemed to pay:

                                    (A) Federal income taxes at the highest
                  applicable marginal rate of Federal income taxation for the
                  calendar year in which the Tax Reimbursement Payment is to be
                  made, and

                                    (B) any applicable state and local income
                  taxes at the highest applicable marginal rate of taxation for
                  the calendar year in which the Tax Reimbursement Payment is to
                  be made, net of the maximum reduction in Federal income taxes
                  which could be obtained from the deduction of such state or
                  local taxes if paid in such year.

                  (d) Adjustments to Tax Reimbursement Payment. In the event
that the Excise Tax is subsequently determined by the Accountants or pursuant to
any proceeding or negotiations with the Internal Revenue Service to be less than
the amount taken into account hereunder in calculating the Tax Reimbursement
Payment made, you shall repay to the Company, at the time that the amount of
such reduction in the Excise Tax is finally determined, the portion of such
prior Tax Reimbursement Payment that would not have been paid if such Excise Tax
had been applied in initially calculating such Tax Reimbursement Payment, plus
interest on the amount of such repayment at the rate provided in Section
1274(b)(2)(B) of the Code. Notwithstanding the foregoing, in the event any
portion of the Tax Reimbursement Payment to be refunded to the Company has been
paid to any Federal, state or local tax authority, repayment thereof shall not
be required until actual refund or credit of such portion has been made to you.
You and the Company shall mutually agree upon the course of action to be pursued
if your good faith claim for refund or credit is denied, provided that the
Company shall bear the cost of any expenses incurred which are related to
pursuing any recovery of any amount paid in respect of the Excise Tax.

                  In the event that the Excise Tax is later determined by the
Accountants or pursuant to any proceeding or negotiations with the Internal
Revenue Service to exceed the amount taken into account hereunder at the time
the Tax Reimbursement Payment is made (including, but not limited to, by reason
of any payment the existence or amount of which cannot be determined at the time
of the Tax Reimbursement Payment), the Company shall make an additional Tax
Reimbursement Payment in respect of such excess (plus any interest or penalty
payable with respect to such excess) at the time that the amount of such excess
is finally determined.

          2.      Definitions.

                  (a) Change of Control When the Company or the Holding
Corporation is Public. A "Change of Control" shall be deemed to have taken place

                           (i) when any "person" or "group" of persons (as such
                  terms are used in Section 13 of the Securities and Exchange
                  Act of 1934, as amended (the "Exchange Act"), other than
                  Holding Corporation, the Company or any majority owned
                  subsidiary of the Holding Corporation or the Company, becomes
                  the "beneficial owner" (as such term is used in Section 13 of
                  the Exchange Act) of 25% or more of the total voting power of
                  the Company's or the Holding Corporation's outstanding
                  securities;

                           (ii) upon the consummation of (A) any merger or other
                  business combination of the Company or the Holding Corporation
                  with or into another company pursuant to which the
                  stockholders of the Company or the Holding Corporation, as the
                  case may be, do not own, immediately after the transaction,

                  of the company that survives, or (B) the sale, exchange or
                  other disposition of all or substantially all of the assets of
                  the Company or the Holding Corporation; or

                           (iii) if, during any period of two years or less,
                  individuals who at the beginning of such period constituted
                  the Board of Directors of the Company or the Holding
                  Corporation, as the case may be, cease for any reason to
                  constitute at least a majority thereof; provided that any new
                  director who is elected to, or nominated for election to, the
                  Board of Directors with the approval of at least 75% of the
                  directors then still in office who were directors at the
                  beginning of the period shall be treated as though having been
                  a director at the beginning of such period.

                  (b) "Qualifying Termination" means the termination of your
employment with the Company and any of its subsidiaries by which you are
employed (i) by the Company or any such subsidiary for any reason other than

                  immediately prior to such Change of Control;

                  reduction in your annual bonus opportunity or a material
                  reduction in the aggregate value of your participation in the
                  Company's employee benefits programs, as each was in effect
                  immediately prior to such Change of Control;

                                    (C) your principal place of employment is
                  moved to a location more than 50 miles from your principal
                  place of employment immediately prior to such Change of
                  Control or you are required in the performance of your duties
                  to travel to an extent substantially more burdensome than your
                  travel obligations immediately prior to such Change of
                  Control; or

                                    (D) the letter of credit or escrow referred

                  accordance with Section 3.1(b).

Notwithstanding anything else contained herein to the contrary, a Qualifying
Termination shall not be deemed to have occurred by reason of (i) your death,
(ii) any termination of your employment due to your inability to perform the
duties of your position for a period of at least 180 days on account of any
physical or mental impairment, or (iii) your voluntary retirement at or after
your normal retirement date under any of the Company's employee pension plans in

arising under or in connection with this Agreement shall be settled exclusively
by arbitration held in accordance with the rules of the American Arbitration
Association pertaining to the resolution of employment disputes. Any such
arbitration shall be held in Chicago, Illinois or such other location which the
parties have mutually agreed to in writing. Judgment may be entered on the
arbitrator's award in any court having jurisdiction. The Company shall pay on a
current basis all legal expenses (including attorneys' fees) incurred by you in
connection with such arbitration, subject to your obligation to repay such

right which the Company may have against you or others whether by reason of your
subsequent employment or otherwise. You shall not be obligated to mitigate any

with the Company and any subsidiary of the Company by which you are employed
terminates following a Change of Control, the amounts payable to you hereunder

benefits referred to in the immediately preceding sentence constitute full
settlement of any claim under law or in equity that you might otherwise assert
against the Company or any of its subsidiaries on account of such termination.

                                      ISDA
                  International Swap Dealers Association, Inc.



                                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

<PAGE>   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:--

               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 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


<PAGE>   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


<PAGE>   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

<PAGE>   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

<PAGE>   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


<PAGE>   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


<PAGE>   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
transmission or electronic messaging system) to the address or number or in
accordance with the electronic messaging system details provided (see the

<PAGE>   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
attempted) or received, as applicable, after the close of business on a Local
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.

(b)      JURISDICTION. With respect to any suit, action or proceedings relating
         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.

<PAGE>   15


(including dealings in foreign exchange and foreign currency deposits) (a) in
relation to any obligation under Section 2(a)(i), in the place(s) specified in
the relevant Confirmation or, if not so specified, as otherwise agreed by the
parties in writing or determined pursuant to provisions contained, or
incorporated by reference, in this Agreement, (b) in relation to any other

in the principal financial centre, if any, of the currency of such payment, (c)
in relation to any notice or other communication, including notice contemplated
under Section 5(a)(i), in the city specified in the address for notice provided
by the recipient and, in the case of a notice contemplated by Section 2(b), in
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

<PAGE>   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
such party applies generally at the time in deciding whether to offer or to make
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
imposed by any government or other taxing authority in respect of any payment
under this Agreement other than a stamp, registration, documentation or similar
tax.

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

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

"TERMINATED TRANSACTIONS" means with respect to any Early Termination Date (a)

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



                                       16                            ISDA(R)1992


<PAGE>   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.

"TERMINATION EVENT" means an Illegality, a Tax Event or a Tax Event Upon Merger
or, if specified to be applicable, a Credit Event Upon Merger or an Additional
Termination Event.

"TERMINATION RATE" means a rate per annum equal to the arithmetic mean of the

by such party) if it were to fund or of funding such amounts.

"UNPAID AMOUNTS" owing to any party means, with respect to an Early Termination
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
this document.

                       [Letterhead of Netherlands Counsel]


                                                                  [Date]

Bank of Montreal
First Canadian Place
Toronto, Ontario
M5X  1A1

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,

                                     Party B an amount equal to the Number of

                                     Forward Settlement Date, the first day on
                                     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


<PAGE>   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
                                     Shares can take place through the relevant
                                     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).

                                       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.
