CHICAGO BRIDGE & IRON COMPANY N.V. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
MARCH 31, 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, 1999. 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 $30,000 of borrowings under the Company's revolving credit facility was 5.57% at March 31, 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 March 31, 1999, new business taken was a solid $193 million, down slightly from the very strong new business taken of $211 million reported in the year-earlier period. Of the new business taken during the first three months of 1999, 55% was for contracts awarded outside of North America. New contract awards in the quarter included a hydroelectric project in North America and tankage for a marine terminal in Russia on the Black Sea at the terminus of the Caspian pipeline. New business taken increased in North America and in the Asia Pacific (AP) area, due in part to expansion of existing work in Australia and success in winning available work in South East Asia. New business taken declined in the Europe, Africa, Middle East (EAME) area and in the Central and South America (CSA) area, with both regions coming off record new business taken levels in the comparable 1998 period. Backlog at March 31, 1999 increased to $523 million, compared with a $508 million backlog at year-end 1998.

Revenues for the first quarter of 1999 were $170.7 million compared with $189.9 million in the first quarter of 1998. Revenues increased 31% 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. Revenues were comparable in the EAME area, while declining 20% in North America and 33% in the AP area in the first quarter, as both regions began 1999 with a lower backlog compared with the prior year.

Gross profit for the three months ended March 31, 1999 increased 6.6% to $18.0 million, or 10.5% of revenues, compared with $16.9 million, or 8.9% of revenues, in the prior year quarter. Higher realized margins on work in North America and improved results in CSA and AP were the primary factors that bolstered gross profit. The future level of 1999 gross profit is dependent in part upon the volume of work, in particular, the attainment of new business taken targets.

Selling and administrative expenses for the quarter ended March 31, 1999 were $11.9 million or 7.0% of revenues, compared with $11.8 million or 6.2% of revenues in the prior year quarter.

8

Income from operations for the first quarter of 1999 increased 21.8% to $6.6 million compared with operating income of $5.4 million for the first quarter of 1998. Operating income was favorably impacted by significantly improved results in CSA, which more than offset lower income in the EAME area, which benefited from several large projects in the 1998 period. Operating income as a percent of revenue increased in North America.

Interest expense was $0.6 million for the first three months 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, which stood at $5 million at year-end 1998, increased during the quarter to a more normal level of $30 million as of March 31, 1999. Cash and cash equivalents at the end of the first quarter were $5.6 million. Interest income consists primarily of interest earned on cash balances at non-U.S. subsidiaries.

For the three months ended March 31, 1999, income tax expense was $1.9 million, or an effective income tax rate of 30%, compared with income tax expense of $1.3 million or an effective income tax rate of 28%, in the prior year quarter. Income tax expense increased in the first quarter of 1999 due to increased income and an anticipated higher effective tax rate.

Net income for the three months ended March 31, 1999 increased 26% to $4.2 million or $0.37 per share, compared with net income of $3.4 million or $0.27 per share for the same period in 1998.

FINANCIAL CONDITION

For the three months ended March 31, 1999, the Company used cash from operations of $20.4 million, primarily due to the timing of cash flows on contracts. The Company continues to carefully scrutinize capital expenditures and held first quarter capital spending to $2.9 million.

On May 12, 1999 the shareholders granted authority to the Management Board of the Company for the repurchase of up to 30% of the Company's current issued share capital through November 12, 2000. These repurchases may take place in the open market, through privately negotiated transactions, equity forward purchases, or by means of a self-tender offer or offers. The Company will evaluate any repurchase method based on current market prices for the common stock and its liquidity needs.

The Company continues to be impacted by the Tuban project in Indonesia, where work remains suspended. At March 31, 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. While the Company believes the Tuban project is viable, it is expected that permanent financing for the project will not be secured until the political and economic situation in Indonesia improves, which is not expected to occur until after the elections in June 1999 at the earliest. The Company believes work on the Tuban project ultimately will resume, but, 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 utilizing 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 foreign currency exchange rate fluctuations through its regular operating and financing activities and, when deemed appropriate, through its limited use of foreign currency forward contracts. The Company's exposure to changes in foreign currency exchange rates arises from receivables, payables and firm commitments from international transactions, as well as intercompany loans utilized 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 foreign currency transactions. Gains or losses are included in income. At March 31, 1999 and December 31, 1998 the Company had foreign currency exchange contracts of less than one year duration. Outstanding foreign currency exchange contracts to purchase Canadian dollars represented $7,830 and $10,034 and foreign currency exchange contracts to sell British pounds represented $2,819 and $2,909 at March 31, 1999 and December 31, 1998, respectively. The Company also had $1,800 and $2,400 of foreign currency exchange contracts to sell Singapore Dollars at March 31, 1999 and December 31, 1998, respectively and had $298 of foreign currency exchange contracts to sell Dutch Guilders at March 31, 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.

Assessment has been completed on all of the Company's worldwide IT systems. As of March 31, 1999, 78% of the Remediation phase for the Company's IT systems was completed. The Remediation phase for all critical areas is scheduled to be completed by August 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 continues on building and mechanical systems with completion scheduled by the end of June 1999. The Remediation phase is scheduled to be completed by August 1999. The Company's assessment and remediation of its fabrication and field construction equipment throughout the world has been completed.

10

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 97% of the North American inquiries and 93% of the non-North American inquiries. The Company continues to work to get responses from suppliers. At this point, it is not possible to forecast 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. 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.

The Company estimates that the cost to remediate its Year 2000 issues is $2.3 million, of which 51% was incurred through March 31, 1999. Approximately $0.5 million of the total cost will be capitalized for the accelerated purchase of desktop hardware. 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 systems capabilities.

The Company has targeted internal compliance with Year 2000 issues for all critical areas, excluding the ongoing J.D. Edwards implementation, by the second quarter of 1999. 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 is developing contingency plans to provide for continuation of its critical operations in spite of possible Year 2000 disruptions. Development of contingency plans is expected to be complete by the end of second quarter 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.

11

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, operating risks, 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.

4.1. NUMBER OF SHARES AVAILABLE FOR GRANTS. Subject to adjustment as provided in Section 4.3 herein, the number of Shares reserved for issuance to Participants under the Plan is 1,130,000.

The maximum aggregate number of Shares with respect to which Awards may be granted in the form of Restricted Stock Shares, Restricted Stock Units, Performance Shares and Performance Units combined in any fiscal year to any Participant is 125,000.

4.2. FORFEITED AND REACQUIRED SHARES. If any Shares subject to any Award are forfeited or such Award otherwise terminates without the issuance of such Shares or of other consideration in lieu of such Shares, the Shares subject to such Award, to the extent of any such forfeiture or termination, shall again be available for grant under the Plan. If Shares are applied to pay the Option price upon exercise of an Option or to satisfy federal, state or local tax withholding requirements pursuant Section 15.2, the Shares so applied shall be added to the Shares permitted under the limitations of Section 4.1 in determining the number of Shares remaining for issuance and for grants of Awards with respect to such Shares under the Plan.

4.3. ADJUSTMENTS IN AUTHORIZED SHARES. In the event of any change in corporate capitalization, such as a stock split, or a corporate transaction, such as a merger, consolidation, separation, spin-off, or other distribution of stock or property of the Company, or any reorganization (whether or not such reorganization comes within the definition of such term in Code Section 368) or any partial or complete liquidation of the Company, the Committee shall adjust the number and class of Shares which may be issued under Section 4.1 and in the limitation of Section 4.1 on grants of Awards with respect to Shares, in the number, class and/or price of Shares subject to outstanding Awards, as the Committee in its sole discretion determines to be appropriate and equitable to prevent dilution or enlargement of rights; provided, however, that the number of Shares subject to any Award shall always be a whole number.

4.4. FRACTIONAL SHARES. No fractional Shares shall be issued to Participants under the Plan. If for any reason an Award or adjustment thereto would otherwise result in the issuance of a fractional Share to a Participant, the Company shall pay the Participant in cash the Fair Market Value of such fractional Share.

ARTICLE 5. - ELIGIBILITY AND PARTICIPATION

5.1. ELIGIBILITY. Persons eligible to participate in this Plan include all Employees, including Employees who are members of the Board, and Nonemployee Directors.

ARTICLE 6. - STOCK OPTIONS.

6.1. GRANT OF OPTIONS. Subject to the terms and provisions of the Plan, the Committee may grant Options to Participants in such number, and upon such terms, and at any time and from time to time, as the Committee in its discretion may determine. The date an Option is granted shall be the day on which the Committee acts to award a specific number of Shares to a Participant at a specific Option Price, and shall be specified in each Award Agreement.

6.2. AWARD AGREEMENT. Each Option grant shall be evidenced by an Award Agreement that shall specify the Option Price, the expiration date of the Option, the number of Shares to which the Option pertains, and such other provisions as the Committee shall determine. The Award Agreement also shall specify whether or not the Option is intended to be an ISO.

6.3. OPTION PRICE. The Option Price for each grant of an Option under this Plan shall be at least equal to 100% of the Fair Market Value of a Share on the date the Option is granted.

6.4. DURATION OF OPTIONS. Each Option shall expire at such time (not later than the 10th anniversary of its date of grant) as the Committee shall determine at the time of grant. If an Award Agreement does not specify an expiration date, the Option shall expire on the 10th anniversary of its date of grant.

6.5. EXERCISE OF OPTIONS. Options shall be exercisable at such times and be subject to such restrictions and conditions as the Committee shall in each instance approve, which need not be the same for each grant or for each Participant.

6.6. PAYMENT. If the Award Agreement does not otherwise specify the manner of exercise, Options shall be exercised by the delivery of a written notice of exercise to CB&I identifying the Option(s) being exercised, completed by the Optionee and delivered during regular business hours to the office of the Secretary of CB&I, or sent by certified mail to the Secretary of CB&I, accompanied by a negotiable check or other cash equivalent in full payment for the Shares. A copy of such notice of exercise shall also be delivered by the Optionee to the office of the Secretary of the Company.

In the discretion of the Committee and as set forth in the Award Agreement, the Optionee may pay the Option Price to CB&I upon exercise of any Option by tendering previously acquired Shares which have been held by the Optionee for at least six months and which have an aggregate Fair Market Value at the time of exercise equal to the total Option Price, or by a combination of such Shares and a check or other cash equivalent.

The Committee also may allow cashless exercise as permitted under Federal Reserve Board's Regulation T, subject to applicable securities law restrictions, or exercise by any other means which the Committee determines to be consistent with the Plan's purpose and applicable law.

Subject to any governing rules or regulations, as soon as practicable after receipt of a written notification of exercise and full payment, CB&I shall deliver, or have delivered, to the, Optionee, in the Optionee's name, certificates for an appropriate number of Shares based upon the number of Shares purchased under the Option(s).

7

8

6.7. RESTRICTIONS ON SHARE TRANSFERABILITY. The Committee may impose such restrictions on any Shares acquired pursuant to the exercise of an Option under this Article 6 as it may deem advisable, including, without limitation, restrictions under applicable securities laws and under the requirements of any stock exchange or market upon which such Shares are then listed and/or traded.

6.8. TERMINATION OF EMPLOYMENT. Each Participant's Option Award Agreement shall set forth the extent to which the Participant shall have the right to exercise the Option following termination of the Participant's employment as an Employee or service as a Director. Such provisions shall be determined in the sole discretion of the Committee, shall be included in the Award Agreement entered into with each Participant, need not be uniform among all Options issued pursuant to this Article 6, and may reflect distinctions based on the reasons for termination of employment.

6.9. NONTRANSFERABILITY OF OPTIONS.

(A) INCENTIVE STOCK OPTIONS. No ISO may be sold, transferred, pledged, assigned, or otherwise alienated, other than by will or by the laws of descent and distribution. Further, all ISOs granted to a Participant under this Article 6 shall be exercisable during his or her lifetime only by such Participant or by designation of a Beneficiary in accordance with Article 10.

(B) NONQUALIFIED STOCK OPTIONS. Except as otherwise provided in a Participant's

Award Agreement, no NQSO may be sold, transferred, pledged, assigned or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution. Further, except as otherwise provided in a Participant's Award Agreement, all NQSOs granted to a Participant under this Article 6 shall be exercisable during his or her lifetime only by such Participant or by designation of a Beneficiary in accordance with Article 10.

ARTICLE 7. - RESTRICTED STOCK.

7.1. GRANT OF RESTRICTED STOCK. Subject to the terms and provisions of the Plan, the Committee may grant Awards of Restricted Stock Shares or Restricted Stock Units to Participants in such amounts and upon such terms, and at any time and from time to time, as the Committee shall in its discretion determine.

7.2. RESTRICTED STOCK AGREEMENT. Each Restricted Stock grant shall be evidenced by a Restricted Stock Award Agreement that shall specify whether the grant is an Award of Restricted Stock Shares or Restricted Stock Units, the Period(s) of Restriction, the number of Shares or Units of Restricted Stock granted, and such other provisions as the Committee shall determine.

7.3. TRANSFERABILITY. Except as otherwise provided in this Article 7, Restricted Stock Units may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated; and Restricted Stock Shares may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction established by the Committee

8

9

and specified in the Restricted Stock Award Agreement, or upon earlier satisfaction of any other conditions, as specified by the Committee in its sole discretion and set forth in the Restricted Stock Award Agreement. Except as otherwise provided in this Article 7, Restricted Stock Shares shall become freely transferable by the Participant upon the Vesting Date, and Shares issued in respect of Restricted Stock Units shall be freely transferable by the Participant upon issuance to the Participant on or after the Vesting Date.

7.4. OTHER RESTRICTIONS. The Committee may impose such other conditions and/or restrictions on any Shares or Units of Restricted Stock granted pursuant to the Plan as it may deem advisable, including, without limitation, a requirement that Participants pay a stipulated purchase price at a stipulated time for each Share or Unit of Restricted Stock, restrictions and conditions of vesting or forfeiture based upon the achievement of specific performance goals (Company-wide, divisional, and/or individual), time-based restrictions on vesting following the attainment of the performance goals, and/or restrictions under applicable Federal or state securities laws.

If the Restricted Stock Award is made in Restricted Stock Shares, CB&I shall retain the certificates representing Shares in CB&I's possession until the Vesting Date. If the Restricted Stock Award is made in Restricted Stock Units, no Shares shall be issued until the Vesting Date, but Shares shall be issued in respect of such Units as of or after the Vesting Date. In either case, certificates for Shares shall be delivered to the Participant on or as soon as practicable after the Vesting Date, or at such later time or times as shall be determined by the Committee in its discretion upon grant of the Award or, with the consent of the Participant, after grant of the Award.

7.5. VOTING RIGHTS. Unless otherwise provided in the Award Agreement, Participants awarded Restricted Stock Shares hereunder which have not been forfeited may exercise full voting rights with respect to those Shares during the Period of Restriction. Restricted Stock Units shall not confer any voting rights (unless and until Shares are issued therefor on or after the Vesting Date).

7.6. DIVIDEND AND OTHER DISTRIBUTIONS. Unless otherwise provided in the Award Agreement, if during the Period of Restriction prior to a Vesting Date or forfeiture of Restricted Stock:

(a) Cash dividends are paid on Shares, (i) the Company shall pay Participants holding Restricted Stock Shares the regular cash dividends paid with respect to the Shares; and (ii) the Company shall pay Participants holding Restricted Stock Units an amount equal to the cash dividends paid on an equivalent number of Shares;

(b) Dividends in Shares are paid in Shares, (i) Participants holding Restricted Stock Shares shall be credited with such dividends as additional Restricted Stock Shares subject to the same restrictions as the underlying Shares; and (ii) Participants holding Restricted Stock Units shall be credited with additional Restricted Stock Units equivalent to such dividends, subject to the same restrictions as the underlying Units.

The Committee may in its discretion apply any restrictions to the dividends that the Committee deems appropriate.

7.7. TERMINATION OF EMPLOYMENT. Except as otherwise provided in the Award Agreement, if the Participant's employment as an Employee or service as a Director with CB&I

9

10

or the Company or their respective Subsidiaries and Affiliates terminates for any reason during the Period of Restriction, all Restricted Stock as to which the Period of Restriction has not yet expired or as to which a Vesting Date has not otherwise occurred shall be forfeited. The Committee in its discretion may set forth in the Award Agreement the extent to which the Participant shall nevertheless have the right to receive vested unrestricted Shares at or after termination of the Participant's employment as an Employee or service as a Director. Such provisions shall be determined in the sole discretion of the Committee, shall be included in the Award Agreement entered into with each Participant, need not be uniform among all Shares or Units of Restricted Stock issued pursuant to the Plan, and may reflect distinctions based on the reasons for termination of employment.

7.8. RIGHTS PERSONAL TO PARTICIPANT. All rights prior to the Vesting Date with respect to the Restricted Stock granted to a Participant under the Plan shall be available during his or her lifetime only to such Participant, or in the event of the Participant's death prior to the Vesting Date, to the Beneficiary designated in accordance with Article 10.

ARTICLE 8. - PERFORMANCE UNITS AND PERFORMANCE SHARES

8.1. GRANT OF PERFORMANCE UNITS/SHARES. Subject to the terms and provisions of the Plan, the Committee may grant Awards of Performance Units and/or Performance Shares to Participants in such amounts and upon such terms, and at any time and from time to time, as the Committee shall in its discretion determine.

8.2. VALUE OF PERFORMANCE UNITS/SHARES. Each Performance Unit shall have an initial value that is established by the Committee at the time of grant. The Committee shall set performance goals in its discretion which, depending on the extent to which they are met, will determine the number and/or value of Performance Units/Shares that will be paid out to the Participant. For purposes of this Article 8, the time period during which the performance goals must be met shall be called a "Performance Period."

8.3. EARNING OF PERFORMANCE UNITS/SHARES. Subject to the terms of this Plan, after the applicable Performance Period has ended, the holder of Performance Units/Shares shall be entitled to receive payout on the number and value of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance goals have been achieved.

8.4. FORM AND TIMING OF PAYMENT OF PERFORMANCE UNITS/SHARES. Payment of earned Performance Units/Shares shall be made in a single lump sum, as soon as practicable after the Committee has certified the number of Performance Units/Shares earned for the Performance Period, or at such later time or times as shall be determined by the Committee in its discretion upon grant of the Award or, with the consent of the Participant, after grant of the Award. Subject to the terms of this Plan and except as otherwise provided in an Award Agreement, the Committee shall pay earned Performance Shares in Shares but may in its sole discretion pay earned Performance Units in the form of cash or in Shares (or in a combination thereof) which have an aggregate Fair Market Value equal to the value as of the date of distribution of the number of earned Performance Units at the close of the applicable Performance Period. Such Shares may be granted subject to any restrictions deemed appropriate by the Committee.

10

11

Unless otherwise provided in the Award Agreement, Participants shall be entitled to receive any dividends paid with respect to Shares which have been earned in connection with grants of Performance Units/Shares but not yet distributed to Participants, such dividends to be subject to the same terms and conditions as apply to dividends earned with respect to Restricted Stock, as set forth in Section 7.6 herein.

8.5. TERMINATION OF EMPLOYMENT DUE TO DEATH, DISABILITY, OR RETIREMENT. Unless determined otherwise by the Committee and set forth in the Participant's Award Agreement, in the event the employment or service as a Director of a Participant is terminated by reason of death, Disability, or Retirement during a Performance Period, the Participant shall receive a payout of the Performance Units/Shares in a reduced amount prorated according to the ratio of the length of Participant's employment or service in the Performance Period to the length of the Performance Period, as specified by the Committee in its discretion. Payment of earned Performance Units/Shares shall be made at a time specified by the Committee in its sole discretion and set forth in the Participant's Award Agreement. Notwithstanding the foregoing, with respect to Named Executive Officers who retire during a Performance Period, payments shall be made at the same time as payments are made to Participants who did not terminate employment or service during the applicable Performance Period.

8.6. TERMINATION OF EMPLOYMENT FOR OTHER REASONS. In the event that a Participant's employment or service terminates for any reason other than those reasons set forth in Section 8.5 herein, all Performance Units/Shares shall be forfeited by the Participant to CB&I unless determined otherwise by the Committee, as set forth in the Participant's Award Agreement.

8.7. NONTRANSFERABILITY. Except as otherwise provided in a Participant's Award Agreement, Performance Units/Shares may not be sold, transferred, pledged, assigned, or otherwise alienated, other than by will or by the laws of descent and distribution or by designation of a Beneficiary in accordance with Article 10. Further, except as otherwise provided in a Participant's Award Agreement, a Participant's rights under the Plan shall be exercisable during the Participant's lifetime only by the Participant or the Participant's legal representative.

ARTICLE 9. - PERFORMANCE MEASURES.

The performance measure(s) to be used for purposes of Awards to Named Executive Officers which are designed to qualify for the Performance-Based Exception shall be chosen from among net income (either before or after interests, taxes, depreciation and amortization), share price, earnings per share, operating income, return on net assets, return on equity, return on capital or investments, total shareholder return, savings in working capital, reduction in expense levels, operating cash flow, free cash flow, or economic value added, in each case where applicable determined either on a Company-wide basis or in respect of any one or more business units.

The Committee shall have the discretion to adjust the determinations of the degree of attainment of the pre-established performance goals; provided, however, that Awards to Named Executive Officers, which are designed to qualify for the Performance-Based Exception, may not be adjusted upward (the Committee shall retain the discretion to adjust such Awards downward).

11

12

In the event that the Committee determines that it is advisable to grant Awards which shall not qualify for the Performance-Based Exception, the Committee may make such grants without satisfying the requirements of Code
Section 162(m).

ARTICLE 10. - BENEFICIARY DESIGNATION

Each Participant under the Plan may, from time to time, name any beneficiary or beneficiaries (who may be named contingently or successively) to whom any benefit under the Plan is to be paid, to exercise any Stock Option, or succeed to the ownership of any Restricted Stock Performance Units/Shares or other Award as provided in this Plan, in case of his or her death before he or she receives any or all of such benefit. Each such designation shall revoke all prior designations by the same Participant, shall be in a form prescribed by the Committee, and will be effective only when filed by the Participant in writing with the Committee during the Participant's lifetime. In the absence of any such designation, benefits remaining unpaid at the Participant's death shall be paid to the Participant's estate.

ARTICLE 11. - DEFERRALS

The Committee may, subject to Section 14.3, in the Award Agreement or otherwise, permit or require a Participant to defer such Participant's receipt of the payment of cash or the delivery of Shares that would otherwise be due to such Participant by virtue of the exercise of an Option, the lapse or waiver of restrictions with respect to Restricted Stock, or the satisfaction of any requirements or goals with respect to Performance Units/Shares. If any such deferral election is required or permitted, the Committee shall, in its sole discretion, establish rules and procedures for such payment deferrals.

ARTICLE 12. - RIGHTS OF EMPLOYEES

12.1. EMPLOYMENT. Nothing in the Plan shall interfere with or limit in any way the right of CB&I to terminate any Participant's employment at any time, nor confer upon any Participant any right to continue in the employ of CB&I.

12.2. PARTICIPATION. No Employee or Director shall have the right to be selected to receive an Award under this Plan, or, having been so selected, to be selected to receive a future Award.

ARTICLE 13. - CHANGE IN CONTROL

(b)Any restriction periods and restrictions imposed on Restricted Shares shall lapse;

12

13

(c)The target payout opportunities attainable under all outstanding Awards of Restricted Stock, Performance Units and Performance Shares shall be deemed to have been fully earned for the entire Performance Period(s) as of the effective date of the Change in Control. The vesting of all Awards denominated in Shares shall be accelerated as of the effective date of the Change in Control, and there shall be paid out in cash to Participants within 30 days following the effective date of the Change in Control an amount based upon an assumed achievement of all relevant performance goals.

13.2. TERMINATION, AMENDMENT, AND MODIFICATIONS OF CHANGE-IN-CONTROL PROVISIONS. Notwithstanding any other provision of this Plan or any provision of any Award Agreement, the provisions of this Article 13 may not be terminated, amended, or modified on or after the date of Change in Control to affect adversely any Award theretofore granted without the prior written consent of the Participant with respect to said Participant's outstanding Awards; provided, however, the Board, upon recommendation of the Committee, may terminate, amend, or modify this Article 13 at any time and from time to time prior to the date of a Change of Control.

ARTICLE 14. AMENDMENT, MODIFICATION, AND TERMINATION

14.1. AMENDMENT, MODIFICATION, AND TERMINATION. The Board may at any time and from time to time, alter, amend, suspend or terminate the Plan in whole or in part.

Section 4.3 hereof) affecting CB&I or the Company, or the financial statements of CB&I or the Company, or of changes in applicable laws, regulations or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan.

14.3. AWARDS PREVIOUSLY GRANTED. The Committee may amend or modify any outstanding Award Agreement in any manner consistent with this Plan for an original Award Agreement, provided, however, that no amendment or modification of an Award Agreement shall adversely affect in any material way the Award previously granted without the written consent of the Participant holding such Award.

Exhibit 10.19

CHICAGO BRIDGE & IRON COMPANY N.V.
INCENTIVE COMPENSATION PROGRAM

OVERVIEW

This Incentive Compensation Program (the "Incentive Program") is designed to align the activities of key managers and other key employees of Chicago Bridge & Iron Company N.V. and its affiliates (the "Company") with the achievement of specific financial performance goals, business unit performance goals, and individual performance objectives. The Company's overall financial goals are (1) to provide an above average return to shareholders and (2) to provide sufficient capital for reinvestment in the business. The Incentive Program's financial targets are set in accordance with these goals. Annual incentive bonuses are paid in cash to eligible Participants depending upon the achievement of financial performance, business performance and individual targets. Achieving these goals will increase the Company's overall competitiveness within the industry, and create increased value for shareholders. The Incentive Program provides a method of rewarding the necessary contributions and leadership behaviors to achieve those results.

The bonus opportunity of a Participant will generally comprise either or both of a "Financial Performance Incentive" (defined below) and a "Unit Performance Incentive" (defined below). However, the Committee reserves the right to grant a "Discretionary Incentive" (defined below) in limited circumstances.

ADMINISTRATION

The Incentive Program is administered by the Organization and Compensation Committee (the "Committee") of the Supervisory Board of Chicago Bridge & Iron Company N.V. The Committee in its discretion construes and interprets the Incentive Program and determines all questions arising under the Incentive Program. The Committee in its discretion directly determines Company-wide financial performance goals, targets and payout percentages for the Financial Performance Incentive for all Participants, and certifies the achievement of such financial performance goals. For the Chief Executive Officer and any other individual who is among the five highest compensated officers of the Company (together with the Chief Executive Officer, the "Covered Executives") in the fiscal year of the Company for which a bonus is payable (the "Bonus Year), the Committee directly determines in its discretion the target Financial Performance Incentive and the extent to which bonus otherwise payable under the Incentive Program shall be reduced on the basis of nonattainment of individual performance goals or other factors. The Committee may in its discretion delegate other administrative responsibilities under the Incentive Program to the management of the Company.

Management of the Company shall make such recommendations to the Committee as the Committee may deem necessary or appropriate for the administration of this Incentive Program.


ELIGIBILITY

Employees of the Company and its affiliates who are in salary grades 16 and above are eligible to be selected to become participants ("Participants") in the Incentive Program. The Committee in its discretion will directly select Covered Executives who may be Participants. Company management with the approval of the Committee in its discretion will select other eligible employees to become Participants. Selection as a Participant for any Bonus Year shall not entitle the individual to be a Participant for any subsequent Bonus Year unless again selected to be a Participant in such subsequent Bonus Year.

A Participant hired during a Bonus Year shall have a prorated target Financial Performance Incentive and (if applicable) a prorated target Unit Performance Incentive, based on the number of weeks worked from the date of hire to the end of the year. A Participant whose employment terminates before the last day of the Bonus Year by reason of a reduction-in-force program, death, disability or retirement, and whose employment terminates on or after April 1 of the Bonus Year, shall have a prorated target Financial Performance Incentive and (if applicable) a prorated target Unit Performance Incentive based on the number of weeks worked from the beginning of the year to the date of termination. A Participant whose employment terminates during the Bonus Year under circumstances not described in the preceding sentence shall not be entitled to a Financial Performance Incentive or Unit Performance Incentive for such Bonus Year.

As a condition to receipt of a bonus a Participant must keep both his or her eligibility and bonus targets strictly confidential. Neither of these may be discussed with, or disclosed to, any individual other than (i) the Vice President of Human Resources, Human Resources staff administering the program, or superiors in the Participant's chain of command, (ii) a Participant's spouse, attorney or accountant who undertake not to further disclose the Participant's eligibility and bonus target, or (iii) in a disclosure required by law.

Notwithstanding anything in this Incentive Program to the contrary, no Participant shall have any vested right to a bonus. The Committee in its sole discretion may reduce or cancel a Participant's incentive bonus for any reason at any time prior to actual payment.

FINANCIAL PERFORMANCE INCENTIVE

A Participant may receive an incentive bonus (a "Financial Performance Incentive") based on his or her bonus target and the achievement by the Company of the Company-wide financial performance goals described below.

Financial Performance Target

The Committee may assign each Participant an individual Financial Performance Incentive target for each Bonus Year. The target for the Financial Performance Incentive is set at a percentage of the Participant's base salary at the time the performance goal is established ("Base Salary") based on the Participant's position and job level. The target amount shall not exceed 100% of Base Salary.


Performance Goals

The Committee selects Company-wide financial performance goals from among (i) operating income, (ii) earnings (before or after any of interest, taxes, depreciation and amortization), (iii) return on net assets, (iv) net income
(before or after taxes), (v) after-tax return on investment, (vi) sales, (vii)
revenues, (viii) earnings per share, (ix) total shareholder return, (x) return on equity, (xi) total business return, (xii) return on gross investment, (xiii) operating cash flow, (xiv) free cash flow, and (xv) economic value added.

Adjustment of Target Incentive for Performance

The Committee may adjust the attainment of any performance goal to reflect or offset (i) a change in accounting standards, (ii) a significant acquisition or divestiture, (iii) a significant capital transaction, or (iv) any other unusual, nonrecurring item; provided in any such case such item is separately identified on the Company's audited financial statements in accordance with generally accepted accounting principles, and is attributable to an event occurring after the performance goals for the year have been established. However, the actual cost of this Incentive Program will be part of the calculation of income from operations.

Thresholds

The Committee selects minimum, target and maximum thresholds for the performance goal it has selected. If performance is less than minimum, no Financial Performance Incentive will be paid. If performance is at the minimum, 20% of the target Financial Performance Incentive may be paid. If performance is at target, 100% of target Financial Performance Incentive may be paid. If performance is at or above maximum, 200% percent of target Financial Performance Incentive may be paid. If performance results fall between two designated thresholds, the Financial Performance Incentive will be determined by interpolation as determined or approved by the Committee. In no event will the Financial Performance Incentive exceed 200% of target Financial Performance Incentive; and in no event will the Financial Performance Incentive exceed 200% of Base Salary.

Application of Goals and Thresholds

A single specific financial performance goal (or fixed combination of more than one financial performance goal) and designated thresholds and payout percentages for that goal or goals selected by the Committee for Company-wide financial performance for any Bonus Year shall be uniformly applicable to all Participants entitled to a Financial Performance Incentive for that Bonus Year. The Committee shall establish the Company-wide financial performance goal or goals, designated thresholds and payout percentages, within the first 90 days of the each year. Prior to the payment of a Financial Performance Incentive and within the first 90 days of the year following the Bonus Year, the Committee shall certify the extent of achievement of the Company-wide financial performance goal or goals for the Bonus Year.

-3-

Discretionary Reduction of Financial Performance Incentive

The Committee in its sole and absolute discretion may reduce the Financial Performance Incentive otherwise determined under this Financial Performance Incentive for any Participant for any reason.

UNIT PERFORMANCE INCENTIVE

A Participant may receive an incentive bonus (a "Unit Performance Incentive") based on his or her Unit Performance Incentive target and the achievement by the Participant's business unit or subunit of the performance goals determined as described below.

Unit Performance Target

The Committee may assign each Participant an individual Unit Performance Incentive target for each Bonus Year. The target for the Unit Performance Incentive is set at a percentage of the Participant's Base Salary based on the Participant's position and job level. The sum of the target amounts for the Financial Performance Incentive and the Unit Performance Incentive shall not exceed 100% of Base Salary.

Performance Goals

The Committee selects business unit performance goals from among (1) the financial performance goals specified above for the Financial Performance Incentive but applied to the business unit or subunit in which the Participant is employed, (2) functional non-financial operating goals specific to such business unit or subunit, (3) operating safety management of the business unit or subunit, or (4) such similar factors as the Committee deems appropriate. To the extent the Committee in its discretion deems feasible, the criteria for measuring attainment of business unit performance goals shall be objective and relate to matters which can be influenced by the Participant in his or her area of responsibilities, and chosen to contribute to meeting the Company's short-and long-term financial goals. The performance goals for the Unit Performance Incentive may be different for each Participant.

Adjustment of Unit Performance Incentive for Performance

The Unit Performance Incentive will be adjusted for unit performance based on the achievement of the applicable performance goals between 20% and 200% of target in the same manner as the Financial Performance Incentive. The Unit Performance Incentive shall also be adjusted for Company-wide financial performance, such that the total of all Unit Performance Incentives does not exceed such amount as the Committee in its discretion shall specify, on the basis of the achievement of Company-wide financial performance. In no event will the Unit Performance Incentive exceed 200% of target Unit Performance Incentive; and in no event will the aggregate

-4-

Financial Performance Incentive and Unit Performance Incentive for any employee exceed 200% of Base Salary.

Discretionary Reduction of Unit Performance Incentive

The Committee in its sole and absolute discretion may reduce the Unit Performance Incentive otherwise determined under this Incentive Program for any Participant for any reason.

DISCRETIONARY INCENTIVE

The Committee may determine that a Participant or any class or group of Participants shall be entitled to a bonus (a "Discretionary Incentive") in an amount determined by the Committee upon a determination by the Committee in its sole discretion, which may take into account individual efforts and contributions of the Participant not necessarily reflected in Company-wide financial performance or business unit performance. The sum of the actual Financial Performance Incentive, Unit Performance Incentive and Discretionary Incentive for any Participant for a Bonus Year will not exceed 200% of Base Salary for the Bonus Year.

MISCELLANEOUS PROVISIONS

Incentive Bonus under this Incentive Program will be payable in cash as soon as practicable after the Committee has certified the achievement of the Company-wide financial performance goal for the Bonus Year and the amount of the incentive bonus is determined.

This Incentive Program shall be effective, beginning with the Company's fiscal year 2000, upon its approval by the shareholders of Chicago Bridge & Iron Company N.V.

The Committee may, without further action by the shareholders, amend this Incentive Program from time to time, effective prospectively or retroactively, in any manner the Committee deems desirable provided, however, that no such amendment shall enlarge the class of employees who may be Participants in this Incentive Program, add to the permitted performance measures for the Financial Performance Incentive, or increase the maximum bonus payable under this Incentive beyond 200% of any Participant's base salary, without the consent of the shareholders of Chicago Bridge & Iron Company N.V.
