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.

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.

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 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.

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.

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 or nonemployee consultant to CB&I 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 or nonemployee consultant. 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 10 death prior to the Vesting Date, to the Beneficiary designated in accordance with Article 10.

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. 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 or nonemployee consultant of a Participant is terminated by reason of death, Disability, or Retirement 11 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). 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). 12 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, Director or nonemployee consultant 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 13.1 TREATMENT OF OUTSTANDING AWARDS. Upon the occurrence of a Change in Control, unless otherwise specifically prohibited under applicable laws, or by the rules and regulations of any governing governmental agencies or national securities exchanges, or unless otherwise provided in an Award Agreement or other written agreement between a Participant and the Company (or CBI or the Committee), then with respect to each Award outstanding on the date of the Change in Control: (a) Any and all Options granted hereunder shall become immediately exercisable, and shall remain exercisable throughout their entire term; (b) Any restriction periods and restrictions imposed on Restricted Shares shall lapse; 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. 14.2. ADJUSTMENT OF AWARDS UPON THE OCCURRENCE OF CERTAIN UNUSUAL OR NONRECURRING EVENTS. The Committee may make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events (including, without limitation, the events described in 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. No termination, amendment or modification of the Plan shall adversely affect in any material way any Award previously granted without the written consent of the Participant holding such Award. ARTICLE 15 - WITHHOLDING 15.1. TAX WITHHOLDING. CB&I shall have the power and the right to deduct or withhold, or require a Participant to remit to CB&I, an amount sufficient to satisfy 14 Federal, state, and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to any taxable event arising as a result of this Plan. 15.2. SHARE WITHHOLDING. With respect to withholding required upon the exercise of Options, upon the lapse of restrictions on Restricted Stock, or upon any other taxable event arising as a result of Awards granted hereunder, Participants may elect, subject to the approval of the Committee, to satisfy the withholding requirement, in whole or in part, by having CB&I withhold Shares having a Fair Market Value on the date the tax is to be determined equal to the minimum statutory total tax which could be imposed on the transaction. All such elections shall be irrevocable, made in writing, and shall be subject to any restrictions or limitations that the Committee, in its sole discretion, deems appropriate. ARTICLE 16. - INDEMNIFICATION Each person who is or shall have been a member of the Committee, or of the Board, shall be indemnified and held harmless by CB&I against and from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim action, suit, or proceeding to which he or she may be party or in which he or she may be involved by reasons of any action taken or failure to act under the Plan and against and from any and all amounts paid by him or her in settlement thereof, with CB&I's approval, or paid by him or her in satisfaction of any judgment of any such action, suit, or proceeding against him or her, provided he or she shall give CB&I an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company's Articles of Association, CB&I's Certificate of Incorporation or Bylaws, any agreement, as a matter of law, or otherwise, or any power that CB&I may have to indemnify them or hold them harmless. ARTICLE 17. - SUCCESSORS All obligations of CB&I under the Plan with respect to Awards granted hereunder shall be binding on any successor to CB&I, whether such successor arises as a result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of CB&I. ARTICLE 18. - LEGAL CONSTRUCTION 18.1. GENDER AND NUMBER. Except where otherwise indicated by the context, any masculine term used herein also shall include the feminine; the plural shall include the singular and the singular shall include the plural. 18.2. SEVERABILITY.

REQUIREMENTS OF LAW. The granting of Awards and the issuance of Shares under the Plan shall be subject to all applicable laws, rules and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. 18.4. SECURITIES LAW COMPLIANCE. Transactions under this Plan are intended to comply with all applicable conditions of Rule 16b-3 under the Exchange Act (or any successor rule). To the extent any provision of the Plan or action by the Committee fails to so comply, it shall be deemed null and void, to the extent permitted by law and deemed advisable by the Committee. 18.5. GOVERNING LAW. To the extent not preempted by federal law, the Plan and all agreements hereunder, shall be construed in accordance with and governed by the laws of the state of Illinois, without regard to its provisions regarding conflict of laws.
