                                     ITEM 1
 
                             ELECTION OF DIRECTORS
 
     The general affairs and business of the Company and the board which manages
the Company (the "Management Board") are supervised by the Supervisory Board
which is appointed by the general meeting of shareholders. The Company's
Articles of Association (the "Articles of Association") provide for at least six
and no more than 12 Supervisory Directors to serve on the Supervisory Board.
Effective March 26, 1997, the size of the Supervisory Board is eight. Under the
law of The Netherlands, a Supervisory Director cannot be a member of the
Management Board ("Managing Directors") of the Company. The shareholders have
appointed Chicago Bridge & Iron Company B.V. as the Management Board. Executive
officers are not Managing Directors of the Company for purposes of Dutch law.
 
                                        1
   5
 
     Members of the Supervisory Board are elected to serve three-year terms,
with approximately one-third of such members' terms expiring each year. Members
of the Supervisory Board must retire no later than at the general meeting of
shareholders held after a period of three years following their appointment, but
may be re-elected. Pursuant to the Articles of Association, members of the
Supervisory Board may be suspended or dismissed by the general meeting of
shareholders. The Supervisory Board may make a proposal to the general meeting
of shareholders for the suspension or dismissal of one or more of its members.
If such proposal is made by the Supervisory Board, a simple majority vote of the
shareholders is required to effect a suspension or dismissal. If no such
proposal is made, the general meeting of shareholders by vote of two-thirds of
the votes cast at the meeting if such two-thirds vote constitutes more than
one-half of the outstanding share capital of the Company (a "Two-thirds Majority
of Quorum") is required to effect a suspension or dismissal. The members of the
Supervisory Board may receive such compensation as may be authorized by the
general meeting.
 
     As permitted under Dutch law and the Articles of Association, the
Supervisory Board is authorized to make binding nominations of two candidates
for each open position on the Supervisory Board, with the candidate receiving
the greater number of votes being elected. This means that a nomination by the
Supervisory Board is binding on the shareholders unless overridden by a
Two-thirds Majority of Quorum.
 
     Two Supervisory Directors are to be elected to serve until the Annual
Meeting of Shareholders in 2001. For one position, the Supervisory Board has
proposed the election of Jerry H. Ballengee or Stephen M. Duffy. For the second
position, the Supervisory Board has proposed the election of L. Donald Simpson
or Kevin C. Yessian. Both Mr. Ballengee and Mr. Simpson are presently members of
the Supervisory Board. Mr. Duffy is Vice President -- Human Resources of Chicago
Bridge & Iron Company and Mr. Yessian is Vice President -- Procurement and
Manufacturing of Chicago Bridge & Iron Company.
 
     THE SUPERVISORY BOARD RECOMMENDS THAT SHAREHOLDERS VOTE FOR MR. BALLENGEE
AND MR. SIMPSON.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     Section 16(a) of the Securities Exchange Act of 1934, as amended, (the
"Exchange Act") requires the Supervisory Directors, Executive Officers and
persons who own more than 10% of the Common Stock to file initial reports of
ownership and reports of changes in ownership (Forms 3, 4 and 5) of Common Stock
with the Securities and Exchange Commission (the "SEC") and the New York Stock
Exchange. Supervisory Directors, Executive Officers and greater than 10%
shareholders are required by SEC regulation to furnish the Company with copies
of all such forms that they file.
 
     To the Company's knowledge based solely on its review of the copies of such
reports received by it and on written representations by certain reporting
persons that no reports on Form 5 were required, the Company believes that
during the fiscal year ended December 31, 1997, its Supervisory Directors,
executive officers and 10% shareholders complied with all Section 16(a) filing
requirements applicable to them.

(1) Salary paid in 1996 for actual period of employment by the Company; Mr.
    Glenn -- May 27, 1996; Mr. Duffy -- June 1, 1996; Mr. Wiggins -- September
    16, 1996; and Mr. Wolfe -- November 18, 1996. Mr. Aldinger was employed by
    the Company during all of 1996.
 
(2) Bonus amounts include payments under the Company's Senior Management
    Incentive Program effective only during 1996 and under the Company's 1996
    Management Incentive Compensation Program which was replaced in 1997 by the
    Annual Incentive Compensation Plan (as described under the caption
    "Organization and Compensation Committee Report on Executive Compensation").
 
(3) The compensation reported for 1996 includes payments under various
    compensation plans and other employment arrangements in effect at the time
    CBI Industries was acquired by Praxair, Inc. ("Praxair") which became
    payable because of such acquisition totaling $240,619 for Mr. Aldinger and
    $7,568 for Mr. Duffy.

     The compensation reported for 1997 represents (a) the value of shares of
     Common Stock contributed pursuant to the Management Plan (as described
     below) (b) contributions pursuant to the Chicago Bridge & Iron Savings Plan
     (the "401(k) plan") allocated to the executive officer's account, (c) the
     cost of allocations to each executive officer's account in a benefit
     restoration plan (described under the caption "Pension and other retirement
     benefits") for allocations pursuant to the 401(k) Plan which otherwise
     exceed the maximum limit imposed upon such plan by the Internal Revenue
     Code of 1986, as amended (the "Code"), (d), reimbursement for moving and
     relocation expenses and (e) the dollar value of split-dollar life insurance
     benefits. Pursuant to an agreement between the Company and Praxair, a trust
     established by Praxair paid the premiums for the split dollar insurance and
     was reimbursed by the Company. The Company expects to recover its
     reimbursements from the policy's cash value at the time premium payments
     are discontinued. For 1997, those five amounts, expressed in the same order
     identified above, for each named executive officer are as follows: Gerald
     M. Glenn, $8,458,092, $12,800, $56,760, $112,695, $0; Thomas L. Aldinger

     $20,050, $0; Robert H. Wolfe $671,868, $12,800, $3,200, $33,222, $0.
 
MANAGEMENT PLAN
 
     The Company has established the Chicago Bridge & Iron Management Defined
Contribution Plan (the "Management Plan").The Management Plan is not qualified
under Section 401(a) of the Code and each participant's account is treated as a
separate account under Section 404(a)(5) of the Code. The designation of
participants, the amount of Company contributions, and the amount allocated to
individual participants was determined by the Management Board. Restrictions on
the Management Plan shares lapse on March 27, 2000, for all participants (except
with respect to one participant, March 27, 1999). Dividends are payable to the
Participants during that period.
 
     As an incentive to increasing the long-term value of the Company, Mr. Glenn
had an agreement with Praxair, and Messrs. Aldinger, Duffy, Wiggins, and Wolfe
have agreements with CB&I, whereby each received special compensation related to
the initial public offer of the Company by Praxair, in March, 1997 (the "IPO"),
in the amounts of 462,000, 110,298, 18,383, 110,298, and 36,766 shares of Common
Stock, respectively. Each of such officers, along with a group of approximately
65 other key management employees, are participants in the Management Plan. In
fulfillment of Praxair's commitment, upon consummation of the IPO, the Company
made a contribution to the Management Plan in the form of 925,670 shares of
Common Stock.
 
EMPLOYEE STOCK PURCHASE PLAN
 
     The Company has adopted a broad-based employee stock purchase plan (the
"Stock Purchase Plan") intended to qualify under Section 423 of the Code.
Pursuant to the Stock Purchase Plan, each employee, including executive
officers, electing to participate is granted an option to purchase shares of
Common Stock on a specified future date at 85% of the fair market value of such
shares on the date of purchase. During specified periods preceding such purchase
date, a percentage of participating employees' after-tax pay is withheld and
used to purchase as many shares of Common Stock as such funds allow at the
discounted purchase price.
 
LONG-TERM COMPENSATION
 
     The Company has adopted the Chicago Bridge & Iron Long-Term Incentive Plan
(the "Incentive Plan") for its executive officers, other management employees
and Supervisory Directors, which is a so-called "omnibus" plan. The Incentive
Plan allows the Company to provide long-term compensation in the following
forms: non-qualified options to purchase shares of Common Stock; qualified
"incentive" options to purchase shares of Common Stock; restricted shares of
Common Stock; "performance shares," paying out a variable number of shares of
Common Stock depending on goal achievement, and "performance units," which would
be cash payments based on either the value of the Common Stock or appreciation
in the price of the Common Stock upon achievement of specific financial goals.
Selection of participating employees and the number of
 
                                        8
   12
 
options to be granted are subject to the approval of the Organization and
Compensation Committee of the Supervisory Board.
 
     The exercise price of all options granted under the Incentive Plan may not
be less than the fair market value of the stock subject to the option on the
date the option is granted. Options are exercisable in accordance with the terms
set forth in individual award agreements, but no option may be exercised before
three years have elapsed from the date of grant. The expiration date of each
option shall not exceed 10 years from the date of grant.
 
     Awards of restricted stock shall be subject to a period of restriction
during which the transfer shall be limited. Such restrictions shall lapse based
on the passage of time, the achievement of performance goals, or the occurrence
of other events as determined by the Organization and Compensation Committee.
 
     Each performance unit shall have an initial value that is established by
the Organization and Compensation Committee at the time of grant, and each
performance share shall have an initial value equal to the fair market value of
a share of Common Stock on the date the award is granted. Holders of performance
units and shares shall be entitled to receive a payout on the number and value
of performance units and shares, based on the achievement during the performance
period of specified performance goals.
 
     In the event of a change in control (as defined in the Incentive Plan),
unless otherwise prohibited under applicable law, all options shall become
immediately exercisable, the restriction period imposed on any restricted stock
award shall lapse and the payout opportunities attainable under all outstanding
awards of restricted stock, performance units and shares shall be deemed to have
been fully earned for the entire performance period.

Incentive Plan during the fiscal year 1997 to and by the executive officers

(1) All options were granted at market value. Options are exercisable after
    April 2, 2000, at the earliest, subject to achievement of a cumulative
    earnings per share for the three-year period from 1997 to 1999 of at least
    $6.25 per share of Common Stock (excluding the pretax charge of $16.7
    million relating to the implementation of the Management Plan). If the
    performance criterion is not met, then the option will become exercisable on
    any succeeding April 2 if such goal, compounded an additional 15% per year,
    is achieved as of the end of the fiscal year then ended preceding such April
    2. If the performance criterion is not met, then the options become
    exercisable on April 2, 2006. Each option will terminate and cease to be
    exercisable if the Participant's employment with the Company terminates for
    any reason other than death, retirement for disability or retirement under a
    retirement plan of the Company.

(2) The estimated grant date present value reflected in the above table is
    determined using the Black-Scholes model. The material assumptions and
    adjustments incorporated in the Black-Scholes model in estimating the value
    of the options reflected in the above table include the following: (a) an
    exercise price of the option of $18.00 equal to the fair market value of the
    underlying stock on the date of grant; (b) an interest rate of 6.89% that
    represents the interest rate on a U.S. treasury security with a maturity
    date corresponding to that of the option term; (c) volatility of 35.242%
    calculated using daily stock prices for the period March 31, 1997 to
    February 12, 1998; (d) dividends at the rate of $0.24 per share,
    representing the annualized dividends paid with respect to a share of Common
    Stock at the date of grant; (e) an approximately 30.67% reduction to reflect
    the probability of forfeiture due to termination prior to vesting and
    approximately 10.98% reduction to reflect the probability of a shortened
    option term due to termination of employment prior to the option expiration
    date; and (f) an option term of ten years. The ultimate values of options
    will depend on the future market price of Common Stock, which cannot be
    forecast with reasonable accuracy. The actual value, if any, an optionee
    will realize upon exercise of an option will depend on the excess of the
    market value of the Common Stock over the exercise price on the date the
    option is exercised.

PENSION AND OTHER RETIREMENT BENEFITS
 
     Effective January 1, 1997, the Company adopted the 401(k) Plan, a tax
qualified defined contribution pension plan for eligible employees, including,
but not limited to, the named executive officers. Such plan consists of a
typical voluntary pretax salary deferral feature under Section 401(k) of the
Code; a dollar-for-dollar Company matching contribution applicable to such
employee deferrals, up to 3% of a participating employee's considered earnings;
a basic additional Company contribution of 5% of each participating employee's
considered earnings; and an additional discretionary Company profit-sharing
contribution.
 
     The 401(k) Plan substantially replaces the CBI 401(k) Pay Deferral Plan and
the CBI Pension Plan, each adopted by the Company's former parent, CBI
Industries, Inc. The 401(k) Plan provides that the Company may, at the
discretion of management, make certain of its matching contribution or
additional discretionary profit sharing contributions in a uniform manner in the
form of either cash or shares of Common Stock.
 
                                       10
   14
 
     The CBI Pension Plan (the "Pension Plan") is non-contributory and covered
substantially all salaried employees and certain hourly employees of the Company
and its participating subsidiaries. Since December 31, 1996 no employees of the
Company participate in the Pension Plan who were not already participants as of
December 31, 1996. No further benefits will accrue under the provisions of the
Pension Plan's normal benefit formulas for employees participating as of
December 31, 1996. Instead, benefits accrued as of that date will be computed
and increased at a rate of 5% per year (not compounded) or fraction thereof of
continuing service, to a maximum of three additional years. The December 31,
1996, accrued pension was based on credited service and average earnings over
the high three consecutive year period and is subject to an offset adjustment
for each individual for primary social security benefits and a portion of the
value of benefits under the terminated CBI Salaried Employee Stock Ownership
Plan (1987) previously sponsored by CBI Industries, Inc. The estimated annual
benefit payable upon retirement at normal retirement age for each of the named
executive officers who participate in the plan is: Thomas L. Aldinger, $52,459;
and Stephen M. Duffy, $8,739.
 
     The Code limited the compensation used to determine benefits under the
401(k) Plan to $160,000 for 1997. Chicago Bridge & Iron Company adopted the
Chicago Bridge & Iron Company Excess Benefit Plan through which it contributes
benefits which would be paid under the 401(k) Plan in the absence of the IRS
limit. Such contributions are paid into a trust, with an independent trustee,
established for this purpose.
 
COMPENSATION OF DIRECTORS
 
     Supervisory Directors who were not employees of the Company received in
1997 an annual retainer of $15,000, paid in quarterly installments, and $1,500
for attendance at each Supervisory Board meeting. Supervisory Directors who were
chairpersons of committees received in 1997 an additional retainer of $2,250.
Those who serve on Supervisory Board Committees receive $1,000 for each
Committee meeting attended. Supervisory Directors who are full-time employees of
the Company receive no compensation for serving as Supervisory Directors.
 
TERMINATION AND EMPLOYMENT AGREEMENTS
 
     The Company and Messrs. Aldinger, Duffy, Wiggins and Wolfe entered into
change of control severance agreements each providing that, in the event of a
termination of their respective employment with the Company (other than by
reason of the employee's willful misconduct or gross negligence) or a
significant reduction in their respective responsibilities, salary or benefits
or a substantive change in the respective location of their employment, within
the two-year period following a change of control of the Company, each will
receive a special lump-sum payment following separation equal to $1,500,000,
$240,000, $1,000,000 and $750,000, respectively. In addition, upon termination
for any reason (other than by reason of the employee's willful misconduct or
gross negligence) during the six-month period prior to a change of control, each
employee will be entitled to receive a special lump-sum payment (in the amount
previously set forth) minus the gross amount of any severance payments otherwise
paid to such employee, within ten days following a change of control. Each
employee who receives a special lump-sum payment is also entitled to receive
outplacement services at the expense of the Company. The agreements provide that
the Company will pay an amount necessary to reimburse each employee, on an
after-tax basis, for any excise tax due under Section 4999 of the Code, as a
result of such payment being treated as a "parachute payment" under Section 280G
of the Code. The receipt by each employee of any of the amounts payable pursuant
to the agreements is contingent upon the employee's execution of a release of
claims in favor of the Company. A change of control for purposes of such
agreements is deemed to occur if, other than in connection with the IPO, (i) any
person or group of persons other than Praxair or one of its subsidiaries becomes
the beneficial owner of 25% or more of the total voting power of the Company's
or any such subsidiary's outstanding securities, (ii) upon consummation of any
merger or other business combination of the Company or any subsidiary with or
into another person pursuant to which the shareholders of the Company or any
such subsidiary do not own, upon consummation or such combination, more than 50%
of the voting power and value of the stock of the surviving person, or (iii) if,
during any period of two years or less, a majority of the
 
                                       11
   15
 
members of the Company's Supervisory Board changes and new members were not
nominated by at least 75% of the Supervisory Directors then still in office who
were supervisory directors at the beginning of such period.
 
     In addition, the Company has entered into employment arrangements with
Messrs. Glenn, Wiggins and Wolfe to serve the Company as President and Chief
Executive Officer, Vice President -- Treasurer and Chief Financial Officer, and
Vice President -- General Counsel and Secretary, respectively. Pursuant to these
arrangements, Mr. Glenn's minimum base salary is $400,000 per year, Mr. Wiggins
minimum base salary is $220,000 per year and Mr. Wolfe's minimum base salary is
$175,000 per year. Such arrangements do not establish any required term of
employment. The arrangements provide for, among other things, participation in
Company bonus and incentive compensation programs, lump-sum payments, in the
amounts specified above, in the event of termination (or a significant reduction
in levels of responsibility) within two years of a sale of the Company and for a
special stock-based compensation award relating to the IPO (as described under
the caption "Management Plan"). Each employee is also entitled to participate in
the Company's relocation program and to receive either an automobile allowance
of $500 per month or the use of a Company-owned vehicle.

                    ORGANIZATION AND COMPENSATION COMMITTEE
                        REPORT ON EXECUTIVE COMPENSATION
 
TO OUR SHAREHOLDERS
 
     On March 26, 1997, Praxair completed the IPO, upon which the Company,
established as a company under the laws of The Netherlands, became a separate,
public company. Prior to the IPO, all decisions on compensation matters that
pertained to the executive officers of the Company for 1997 were considered by,
and were made in the context of the compensation policies followed by, the
senior management of Praxair.
 
     The current Supervisory Board of the Company was elected in connection with
the IPO and the current members of the Company's Organization and Compensation
Committee (the "Committee") were appointed effective June 6, 1997. Since its
inception, the Committee has reviewed and approved certain compensation actions
relating to the Company's 1997 fiscal period, which actions are described in
this report. The Committee has also considered and approved a policy for
executive compensation, which is described below.
 
COMMITTEE ROLE IN OVERSEEING EXECUTIVE COMPENSATION POLICY
 
     A primary role of the Committee is to determine and oversee the
administration of compensation for the Company's executive officers. In this
capacity, the Committee is dedicated to ensuring that the Company's compensation
policies and practices are used effectively to support the achievement of the
Company's short-and long-term business objectives.
 
     To preserve objectivity in the achievement of its goals, the Committee is
comprised of independent, non-employee directors who have no "interlocking"
relationships, as defined by the SEC. The Committee approves the design of,
assesses the effectiveness of, and administers executive compensation programs
in support of compensation policies. The Committee also reviews and approves all
salary arrangements and other remuneration for executives, evaluates executive
performance and considers related matters.
 
     In 1992, the SEC amended the proxy statement rules regarding the disclosure
of executive compensation for officers and directors of reporting companies. The
current rules require a report on executive compensation to be submitted by the
compensation committee of the Board of Directors of regulated, publicly-traded
companies (which includes the Company, even though not organized under the laws
of a state in the United States). The purpose of the report is to inform
shareholders of the Committee's compensation policies for executive officers and
the rationale for compensation paid to the Chief Executive Officer ("CEO"). This
report, submitted by the Committee, follows.
 
COMPENSATION PHILOSOPHY
 
     The Company is committed to increasing shareholder value by growing its
business in the global marketplace. To accomplish this objective, the Company
has developed a combination of strategic initiatives.
 
     The Company's overall compensation philosophy is to remain competitive with
comparable companies while focusing on performance-based compensation. This
philosophy is premised on the fact that the Company must compete with a wide
variety of construction and engineering related firms in order to attract and
develop a pool of talented employees. The philosophy also acknowledges the need
to focus employees on the Company's financial performance, especially in view of
the Company's transition to a freestanding entity through the IPO. The Company's
compensation philosophy includes the following factors:
 
     - Utilize programs that will attract new talent and retain key people
 
     - Pay competitively with significant focus on incentive compensation
 
     - Use equity compensation for top managers to motivate value creation for
       all shareholders
 
     - Develop plans with a higher percentage of pay "at-risk" (based on
       performance) than typical marketplace practice
 
                                       13
   17
 
     The Committee has determined appropriate target levels for base salary,
annual incentives and long-term compensation. Base salaries should be targeted
at or near the 50th percentile of the market, and individual pay determinations
and increases will be based on individual responsibilities and contributions.
Annual incentives will be targeted at the 50th percentile of market, with
opportunities for additional rewards for superior performance. Long-term
compensation will consist primarily of stock options, with targeted awards which
are above competitive levels, thus creating the opportunity for Participants to
receive above average levels of compensation based on appreciation in the value
of the Common Stock.
 
     Competitive market data is provided by a major independent global
compensation consultant, Hewitt Associates LLC, of Lincolnshire, Illinois. The
data provided compares the Company's compensation practices to a group of
"comparator" companies. The Company's market for compensation comparison
purposes is comprised of a group of companies which tend to have national and
international business operations and similar lines of business, as well as
companies operating in the same geographic areas and competing for management
employees in the same areas of expertise as the Company. The Committee reviews
and approves the selection of companies used for compensation comparison
purposes, based on its assessment of the comparability of the above factors.
 
     The companies chosen for the comparator group used for compensation
purposes generally are not the same companies which comprise the peer group
index in the Performance Graph included in this proxy statement. Considering the
factors described above, the Committee believes that the Company's most direct
competitors for executive talent are not necessarily the companies that would be
included in a peer group established for comparing shareholder returns.
 
     The key elements of the Company's executive compensation are base salary,
annual incentives, long-term incentives and benefits. These key elements are
addressed separately below. In determining compensation, the Committee considers
all elements of an executive officer's total compensation package.
 
BASE SALARIES
 
     The Committee will regularly review each executive officer's base salary.
Base salaries are targeted at market levels. Base salaries for executive
officers are initially determined by evaluating executives' levels of
responsibility, prior experience, breadth of knowledge, internal equity within
the Company and external pay practices.
 
     Base salaries provide the underlying level of compensation security to
executives and allow the Company to attract competent executive talent and
maintain a stable management team. They also allow executives to be rewarded for
individual performance based on the Company's evaluation process. Base salary
increases for individual performance reward executives for achieving goals which
may not be immediately evident in common financial measurements.
 
     Individual performance is evaluated based on sustained levels of individual
contribution to the Company. When evaluating individual performance, the
Committee considers the executive's efforts in promoting Company values;
continuing educational and management training; improving project quality;
developing relationships with clients, suppliers, and employees; demonstrating
leadership abilities among coworkers; and other goals. Overall, executive
salaries were increased in 1997 at a rate comparable to the increases provided
at other companies and are near market levels.
 
     In 1996, Praxair entered into an employment agreement with Mr. Glenn (the
"Employment Agreement"), providing that Mr. Glenn would serve as the President
and Chief Executive Officer of the Company's predecessor. Following the IPO, the
Company assumed the Employment Agreement with Mr. Glenn.
 
     The Employment Agreement provided for Mr. Glenn to receive a minimum base
salary of $400,000 per annum. The Employment Agreement did not provide for any
increase in 1997, and Mr. Glenn did not receive any. In 1997, Mr. Glenn actually
received total base salary payments of $400,000, as reflected in the Summary
Compensation Table on page 7.
 
                                       14
   18
 
ANNUAL INCENTIVES
 
     The Company adopted the Annual Incentive Compensation Plan (the "Bonus
Plan"), which took effect in fiscal 1997. The Bonus Plan is an annual short-term
incentive plan covering a group consisting of the executive officers of the
Company and its principal operating subsidiaries, and other designated key
management employees. The Bonus Plan is based on the annual operating plan of
the Company, arrived at as a result of discussion and analysis of the business
plans within the major divisions of the Company. Payment of bonuses is based on
attaining a specific goal of operating income, and other factors described
below, and is payable following the end of the fiscal year. The operating income
goal will be set from year to year, at the beginning of each year (subject to
modifications relating to extraordinary events), upon management's
recommendation and approval by the Supervisory Board.
 
     A target bonus will be established for each participating employee at the
beginning of each year based on position, responsibilities and grade level. The
bonus may be earned from three sources: achievement of the corporate operating
income goal, achievement of a cash management goal and achievement of individual
performance goals. A percentage of target bonus opportunity is allocated to each
bonus source. The individual performance bonus is determined by the management's
evaluation, and in the case of the CEO, by the Committee.
 
     For fiscal 1997, Mr. Glenn and the Company's other executive officers
received bonus payments pursuant to the Bonus Plan. Mr. Glenn received a bonus
payment of $155,000. Mr. Glenn's bonus payment was below his target bonus. There
was no bonus payment relating to the corporate operating income goal for 1997.
In 1997, Mr. Glenn's annual bonus payment represented 39% of his base salary as
is reflected in the Summary Table on page 7, and depending on achievement of the
respective goals under the Plan, could have ranged from 0% to 110% of his base
pay. Mr. Glenn's bonus is below the median of annual incentive compensation paid
other executives at comparator companies for 1997.
 
LONG-TERM INCENTIVES
 
     In keeping with the Company's commitment to provide a total compensation
package which favors at-risk components of pay, long-term incentives comprise a
significant portion of an executive's total compensation package. The
Committee's objective is to provide executives with long-term incentive award
opportunities that are above market levels.
 
     Long-term incentives are provided pursuant to the Chicago Bridge & Iron
Long-Term Incentive Plan ("Incentive Plan"). When awarding long-term incentives,
the Committee considers executives' levels of responsibility, prior experience,
historical award data, various performance criteria and compensation practices
at comparator companies.
 
     Stock options are granted under the Incentive Plan at an option price not
less than the fair market value of the Common Stock on the date of grant.
Accordingly, stock options have value only if the stock price appreciates from
the date the options are granted. This design focuses executives on the creation
of shareholder value over the long term and identification with shareholders'
interests, and encourages equity ownership in the Company.
 
     Initial stock options granted in 1997 under the Incentive Plan may become
exercisable after March, 2000 subject to achievement of a cumulative earnings
per share for the three-year period from 1997 through 1999 of at least $6.25 per
share of Common Stock (excluding a pretax charge of approximately $16.7 million
relating to the implementation of the Management Plan discussed on page 8). All
of such options which have not previously vested otherwise under the terms of
the Incentive Plan will vest automatically nine years from their date of grant.
The Incentive Plan will have a life of five years for the purpose of making
grants or awards, unless the number of shares reserved for such plan are used up
before the expiration of that period, in which case shareholder approval will be
required in order to reserve additional shares of Common Stock for the Incentive
Plan. The vesting and exercise periods for options granted will run
independently of, and be in addition to, such five-year period.
 
                                       15
   19
 
     In 1997, Mr. Glenn received options to purchase 92,094 shares with an
exercise price of $18.00, as is detailed in the table on page 9. Mr. Glenn also
currently owns or has beneficial ownership of 470,094 shares of the Company's
Common Stock, as shown on page 6. These equity interests provide an alignment
with the interests of other shareholders appropriate to Mr. Glenn's position and
responsibilities for management of the Company.
 
BENEFITS
 
     In general, benefits provide a safety net of protection against financial
catastrophes that can result from illness, disability, or death. The benefits
offered by the Company to key executives are generally the same as those offered
to the overall employee population with some variation to promote replacement of
benefit opportunities lost to regulatory limits, as discussed on page 11.
 
INTERNAL REVENUE CODE 162(M) CONSIDERATIONS
 
     Section 162(m) of the Internal Revenue Code of 1986 ("Code") provides that
executive compensation in excess of $1 million will not be deductible for
purposes of U.S. corporate income taxes unless it is "performance-based"
compensation and is paid pursuant to a plan meeting certain requirements of the
Code. The Committee's primary obligation is to promote, recognize and reward
performance which increases shareholder value, and the Committee accordingly
will continue to rely on performance-based compensation programs which are
designed to achieve that goal. The Committee will give appropriate consideration
to the requirements of Section 162(m) in the design of any such programs, but
will also exercise its discretion to determine, according to the best overall
interests of the Company, whether to recommend or adopt a program which complies
with such requirements.
 
     The Committee believes that all compensation actually paid in respect of
1997 was deductible.
 
CONCLUSION
 
     The Committee believes these executive compensation policies and programs
serve the interests of shareholders and the Company effectively. The various pay
vehicles offered are appropriately balanced to provide increased motivation for
executives to contribute to the Company's overall future success, thereby
enhancing the value of the Company for the shareholders' benefit.
 
     We will continue to monitor the effectiveness of the Company's total
compensation program to meet the current needs of the Company.

                          APPROVAL OF ANNUAL ACCOUNTS
 
     At the Annual Meeting, the shareholders will be asked to authorize the
preparation of the annual accounts and the annual report in the English language
and to adopt the Dutch Statutory Annual Accounts of the Company for the fiscal
year ended December 31, 1997 (the "Annual Accounts"), as required under Dutch
law and the Articles of Association. Copies of the Annual Accounts, the report
of the Management Board and the list of nominees for the Supervisory Board can
be obtained free of charge by shareholders and other persons entitled to attend
meetings of shareholders of the Company at the offices of the Company at
Koningslaan 34, 1075 AD Amsterdam, The Netherlands; at Kas Associatie N.V.
Spuistraat 172, 1012 VT Amsterdam, The Netherlands; and at the Bank of New York,
101 Barclay Street, 22nd Floor West, New York, New York 10286 from the date
hereof until the close of the Annual Meeting.
 
     The Annual Accounts are prepared in accordance with Dutch law and
International Accounting Standards ("IAS"). However, the Annual Accounts are
substantially similar to the financial statements contained in the Company's
1997 Annual Report to Shareholders (the "Annual Report") accompanying this Proxy
Statement, which were prepared in accordance with generally accepted accounting
principles in the United States ("U.S. GAAP"). The Annual Accounts contain
certain disclosures not required under U.S. GAAP. In addition, the Management
Report required by Dutch law although substantially similar to the Management's
Discussion and Analysis of Financial Conditions and Results of Operations
included in the Annual Report, also contains information included in the
Company's Annual Report on Form 10-K and other information required by Dutch
law.
 
     Under Dutch law and the Articles of Association, adoption of the Annual
Accounts by the shareholders discharges the members of the Management Board and
the Supervisory Board from liability in respect of the exercise of their duties
during the financial year concerned, unless an explicit reservation is made by
the Annual Meeting and without prejudice to the provisions of the law of The
Netherlands relating to liability upon bankruptcy. Under the law of The
Netherlands, this discharge from liability does not extend to matters not
disclosed to shareholders.
 
     The affirmative vote of the holders of a majority of the Common Stock
present or represented by proxy and entitled to vote at the Annual Meeting is
required to adopt the Annual Accounts.
 
     THE SUPERVISORY BOARD RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" THE ADOPTION
OF THE ANNUAL ACCOUNTS, AND PROXIES EXECUTED AND RETURNED WILL BE SO VOTED
UNLESS CONTRARY INSTRUCTIONS ARE INDICATED THEREON.
 
                                     ITEM 3
 
                            DISTRIBUTION OF PROFITS
                       (in thousands, except share data)
 
     The Company's Articles of Association provide that "from 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 after (such)
reservation... are at the disposal of the general meeting for distribution on
the shares equally and proportionally and/or for reservation." As permitted
under the Company's Articles of Association, interim dividends were paid in 1997
on June 30, September 30 and December 30 and in 1998 on March 30 ("interim
dividends").
 
     It is proposed that the shareholders approve the distribution of 1997
profits in the amount of $0.24 per share of common stock ($2,989) paid as
interim dividends, and a transfer of the balance of the profits to retained
earnings. The Company's financial statements reflect $2,253 in interim dividends
paid to shareholders as of December 31, 1997. The balance of 1997 profits was
transferred to retained earnings, including $736 which was paid to shareholders
as an interim dividend subsequent to year end.

     The affirmative vote of the holders of a majority of the Common Stock
present or represented by proxy and entitled to vote at the Annual Meeting is
required to approve the distribution of profits.
 
     THE SUPERVISORY BOARD RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" APPROVAL OF
THE DISTRIBUTION OF PROFITS PAID IN THE FORM OF INTERIM DIVIDENDS, AND PROXIES
EXECUTED AND RETURNED WILL BE SO VOTED UNLESS CONTRARY INSTRUCTIONS ARE
INDICATED THEREON.
 
                                     ITEM 4
 
            EXTENSION OF AUTHORITY OF MANAGEMENT BOARD TO REPURCHASE
       SHARES OF THE SHARE CAPITAL OF THE COMPANY UNTIL NOVEMBER 12, 1999
 
     Under Dutch law and the Articles of Association, the Management Board may,
subject to certain Dutch statutory provisions, authorize the Company to
repurchase up to 10% of the Company's Common Stock in open market purchases at
any price not to exceed 110% of the then market price. At March 20, 1998, the
Company held 249,700 shares of Common Stock, leaving 977,085 shares of Common
Stock which it could acquire under this limitation. Any such purchases are
subject to the approval of the Supervisory Board and the authorization of
shareholders at the Annual Meeting, which authorization may not continue for
more than eighteen months, but may be renewed on an annual rolling basis. In
connection with the IPO, the shareholders authorized the Supervisory Board for
an eighteen-month period to repurchase shares of the Common Stock. This
eighteen-month period is set to expire on September 25, 1998.
 
     At the Annual Meeting, the shareholders will be asked to approve a further
extension of this authority for an additional eighteen-month period from the
date of the Annual Meeting until November 12, 1999.
 
     The affirmative vote of the holders of a majority of the Common Stock
present or represented by proxy and entitled to vote at the Annual Meeting is
required to extend the authorization of the Management Board to authorize the
Company to repurchase up to 10% of the Common Stock for an additional
eighteen-month period from the date of the Annual Meeting.
 
     THE SUPERVISORY BOARD RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" THE EXTENSION
OF THE AUTHORITY OF THE MANAGEMENT BOARD TO REPURCHASE UP TO 10% OF THE
OUTSTANDING SHARE CAPITAL OF THE COMPANY UNTIL NOVEMBER 12, 1999, AND PROXIES
EXECUTED AND RETURNED WILL BE SO VOTED UNLESS CONTRARY INSTRUCTIONS ARE
INDICATED THEREON.
 
                                     ITEM 5
 
          EXTENSION OF AUTHORITY OF SUPERVISORY BOARD TO ISSUE SHARES
                       OF COMMON STOCK UNTIL MAY 12, 2003
 
     At the Annual Meeting, the shareholders will be asked to approve a further
extension of the authority of the Supervisory Board to issue and/or grant rights
(including options to purchase unissued shares) on shares of Common Stock for a
five-year period from the date of the Annual Meeting until May 12, 2003. A
designation may be effective for up to five years and may be renewed on an
annual rolling basis. In connection with the IPO, the shareholders authorized
the Supervisory Board for a five-year period to issue and/or grant rights
(including options to purchase) on shares of Common Stock. This five-year period
is set to expire on March 25, 2002. (For a discussion of preemptive rights held
by holders of Common Stock, see Item 6 below.)
 
     At the Annual Meeting, the shareholders will be asked to approve a further
extension of this authority for a five-year period from the date of the Annual
Meeting until May 12, 2003.
 
     The affirmative vote of the holders of a majority of the Common Stock
present or represented by proxy and entitled to vote at the Annual Meeting is
required to extend the authorization of the Supervisory Board to issue and/or to
grant rights (including options to purchase unissued shares) on Common Stock for
a five-year period from the date of the Annual Meeting.

     THE SUPERVISORY BOARD RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" THE EXTENSION
OF THE AUTHORITY OF THE SUPERVISORY BOARD TO ISSUE AND/OR GRANT RIGHTS

EXECUTED AND RETURNED WILL BE SO VOTED UNLESS CONTRARY INSTRUCTIONS ARE

                                     ITEM 6
 
       EXTENSION OF AUTHORITY OF SUPERVISORY BOARD TO LIMIT OR ELIMINATE
                      PREEMPTIVE RIGHTS UNTIL MAY 12, 2003
 
     Under Dutch law and the Articles of Association, holders of Common Stock
have a prorata preemptive right of subscription to any shares of Common Stock
issued for cash unless such right is limited or eliminated. Holders of Common
Stock have no prorata preemptive subscription right with respect to any Common
Stock issued for consideration other than cash or pursuant to employee stock
plans. If designated for this purpose at the Annual Meeting, the Supervisory
Board has the power to limit or eliminate such rights. A designation may be
effective for up to five years and may be renewed on an annual rolling basis. In
connection with the IPO, the shareholders authorized the Supervisory Board for a
five-year period to limit or eliminate from time to time the preemptive rights
of holders of Common Stock. This five-year period is set to expire on March 25,
2002.
 
     At the Annual Meeting, the shareholders will be asked to approve a further
extension of this authority for a five-year period from the date of the Annual
Meeting until May 12, 2003.
 
     The affirmative vote of the holders of a majority of the Common Stock
present or represented by proxy and entitled to vote at the Annual Meeting is
required to extend the authorization of the Supervisory Board to limit or
eliminate the preemptive rights of holders of Common Stock for a five-year
period from the date of the Annual Meeting.
 
     THE SUPERVISORY BOARD RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" THE EXTENSION
OF THE AUTHORITY OF THE SUPERVISORY BOARD TO LIMIT OR ELIMINATE PREEMPTIVE
RIGHTS OF HOLDERS OF COMMON STOCK UNTIL MAY 12, 2003, AND PROXIES EXECUTED AND
RETURNED WILL BE SO VOTED UNLESS CONTRARY INSTRUCTIONS ARE INDICATED THEREON.
 
                                     ITEM 7
 
                      TO AMEND THE ARTICLES OF ASSOCIATION
 
     The Company's Articles of Association provide that Praxair be entitled to
appoint two Supervisory Directors if it owns more than 20% of the outstanding
Common Stock and one Supervisory Director if it owns more than 10% of the
outstanding Common Stock. Such Supervisory Directors may only be dismissed or
replaced by Praxair. Since Praxair no longer owns any shares of Common Stock,
the provisions are inoperative. At the Annual Meeting, the shareholders will be
asked to amend the Articles of Association by deleting these provisions.
 
     As restated for this amendment, the provisions in the Articles of
Association will be as follows:
 
     "Article 20. Appointment
 
     1. All members of the supervisory board shall be appointed by the general
        meeting from a nomination of at least two persons for every position to
        be filled, which has been drawn up by the supervisory board.
 
     2. The provisions in paragraph 2 and 3 of article 12 shall likewise apply
        to an appointment by the general meeting.
 
     3. No person who has reached the age of seventy-two may be appointed as a
        supervisory board member.
 
                                       20
   24
 
     Article 21. Suspension And Dismissal. Retirement.
 
     1. Every member of the supervisory board may be suspended or dismissed by
        the general meeting at any time.
 
     2. The provisions in paragraph 2 of article 13 shall similarly apply to the
        suspension and dismissal of supervisory board members by the general
        meeting.
 
     3. A supervisory board member shall retire no later than at the next annual
        meeting held after a period of three years following his appointment. A
        so retired member of the supervisory board may be immediately
        re-elected.
 
     4. Every member of the supervisory board shall retire no later than on the
        day on which the annual meeting is held in the financial year in which
        he reaches the age of seventy-two.
 
     5. With due observance of the preceding paragraphs the supervisory board
        shall draw up a rotation plan."
 
     The affirmative vote of the holders of a majority of the Common Stock
present or represented by proxy and entitled to vote at the Annual Meeting is
required to amend the Articles of Association.
 
     THE SUPERVISORY BOARD RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" THE
AMENDMENTS TO THE ARTICLES OF ASSOCIATION, AND PROXIES EXECUTED AND RETURNED
WILL BE SO VOTED UNLESS CONTRARY INSTRUCTIONS ARE INDICATED THEREON.
 
                                     ITEM 8
 
                 RATIFICATION OF APPOINTMENT OF ARTHUR ANDERSEN
             AS INDEPENDENT PUBLIC AUDITORS OF THE COMPANY FOR 1998
 
     The Supervisory Board has appointed the firm of Arthur Andersen as the
Company's independent public auditors for the year ending December 31, 1998,
subject to ratification by the shareholders. Arthur Andersen has acted as the
Company's auditors since inception and of the Company's predecessors since 1939.
Representatives of Arthur Andersen are expected to be present at the Annual
Meeting. They will have an opportunity to make a statement, if they desire, and
are expected to be available to respond to appropriate questions.
 
     The affirmative vote of the holders of a majority of the Common Stock
present or represented by proxy and entitled to vote at the Annual Meeting is
required to ratify the appointment of Arthur Andersen as the Company's
independent public auditors for 1998.
 
     THE SUPERVISORY BOARD RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" THE
RATIFICATION OF ARTHUR ANDERSEN'S APPOINTMENT AS THE COMPANY'S INDEPENDENT
PUBLIC AUDITORS FOR 1998, AND PROXIES EXECUTED AND RETURNED WILL BE SO VOTED

                                 OTHER MATTERS
 
     The Supervisory Board does not know of any other matters that are to be
presented for action at the Annual Meeting. However, if any other matters
properly come before the Annual Meeting or any adjournment(s) thereof, it is
intended that the enclosed proxy will be voted in accordance with the judgment
of the persons voting the proxy.

                             SHAREHOLDER PROPOSALS
 
     Any proposal of a shareholder intended to be presented at the 1999 Annual
Meeting of Shareholders must be received at the Company's principal executive
offices no later than December 14, 1998, if the proposal is to be considered for
inclusion in the Company's proxy statement relating to such meeting.
