RECITALS:

A. The Obligors and each of the Noteholders have heretofore entered into the Note Purchase and Guarantee Agreement dated as of July 22, 2015 (as amended, amended and restated, supplemented or otherwise modified, the “Note Purchase Agreement”), pursuant to which the Company issued U.S. $200,000,000 aggregate principal amount of its 4.53% Senior Notes, due July 30, 2025 (the “Notes”).

B. The Company and the Noteholders now desire to amend the Note Purchase Agreement in the respects, but only in the respects, hereinafter set forth.

C. Capitalized terms used herein shall have the respective meanings ascribed thereto in the Note Purchase Agreement unless herein defined or the context shall otherwise require.

D. All requirements of law have been fully complied with and all other acts and things necessary to make this Amendment a valid, legal and binding instrument according to its terms for the purposes herein expressed have been done or performed.

NOW, THEREFORE, the Obligors and the Noteholders, in consideration of good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, do hereby agree as follows:

1. Amendments to Note Purchase Agreement. Subject to the terms and conditions set forth herein, the Note Purchase Agreement (exclusive of Schedules thereto) is amended as follows:

(a) Section 10.3 of the Note Purchase Agreement is hereby amended by amending and restating the initial proviso to the final paragraph thereto to read as follows: “provided that there shall be excluded from any determination of a “substantial part” any (i) sale or disposition of assets in the ordinary course of business of the Obligors and their Subsidiaries (including sales or dispositions of worthless, damaged or obsolete equipment), (ii) any transfer of assets from any Obligor to any Subsidiary or from any Subsidiary to any Obligor or another Subsidiary, (iii) any sale or disposition in connection with Project Bluefin consummated on or prior to March 31, 2016 and (iv) any sale or disposition of property acquired by any Obligor or any Subsidiary after the date of this Agreement to any Person within 365 days following the acquisition or construction of such property by Obligor or such Subsidiary if an Obligor or such Subsidiary shall concurrently with such sale or other disposition, lease such property, as lessee;”.

(b) Section 10.8 of the Note Purchase Agreement is hereby amended and restated in its entirety to read as follows:

“(b) The Parent Guarantor shall not permit its Consolidated Net Worth at any time on or after September 30, 2015 to be less than the sum of (x) seventy-five

percent (75%) of the actual net worth of the Parent Guarantor and its Subsidiaries on a consolidated basis as of September 30, 2015 plus (y) fifty percent (50%) of the sum of Consolidated Net Income (if positive) earned in each fiscal quarter, commencing with the fiscal quarter ending on December 31, 2015.”

2. Amendment to Defined Terms. Schedule B to the Note Purchase Agreement is hereby amended by adding the following new definition in its proper alphabetical order:

‘“Project Bluefin” means, collectively, the acquisition by a direct, wholly owned subsidiary of Westinghouse Electric Company LLC (“WECLLC”) of all of the issued and outstanding shares of capital stock or membership interests of CB&I Stone & Webster, Inc. (the “Transferred Company”) pursuant to that certain Purchase Agreement by and among the Parent Guarantor, the Transferred Company, WECLLC and a direct, wholly owned subsidiary of WECLLC, as amended, and all transactions, sales of assets and dispositions pursuant thereto and in connection therewith.”’

3. Representations and Warranties of the Obligors. To induce the Noteholders to execute and deliver this Amendment (which representations shall survive the execution and delivery of this Amendment), each Obligor represents and warrants to the Noteholders that:

(a) this Amendment has been duly authorized, executed and delivered by it and this Amendment constitutes the legal, valid and binding obligation, contract and agreement of such Obligor enforceable against it in accordance with its terms, except as enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws or equitable principles relating to or limiting creditors’ rights generally;

(b) the Note Purchase Agreement, as amended by this Amendment, constitutes the legal, valid and binding obligation, contract and agreement of such Obligor enforceable against it in accordance with its terms, except as enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws or equitable principles relating to or limiting creditors’ rights generally;

(c) the execution, delivery and performance by such Obligor of this Amendment (i) has been duly authorized by all requisite corporate action and, if required, shareholder action, (ii) does not require the consent or approval of any governmental or regulatory body or agency, and (iii) will not (A) violate (1) any provision of law, statute, rule or regulation or its certificate of incorporation or bylaws, (2) any order of any court or any rule, regulation or order of any other agency or government binding upon it, or (3) any provision of any indenture, agreement or other instrument to which it is a party or by which its properties or assets are or may be bound, including, without limitation, any Credit Agreement, or (B) result in a breach or constitute (alone or with due notice or lapse of time or both) a default under any indenture, agreement or other instrument referred to in clause
(iii)(A)(3) of this Section 3(c);

(d) as of the date hereof immediately prior to and after giving effect to this Amendment, no Default or Event of Default has occurred which is continuing;

(e) no fee or form of other consideration is being given to any lender under any outstanding Credit Agreement to consent to the amendment to the Credit Agreements entered into on the date hereof;

(f) CB&I Stone & Webster, Inc.

(g) all of the representations and warranties contained in Section 5 of the Note Purchase Agreement are true and correct in all material respects (in all respects in the case of representations and warranties qualified by materiality, Material Adverse Effect or similar language in the text thereof) with the same force and effect as if made by such Obligor on and as of the date hereof, except to the extent that such representations and warranties expressly relate solely to an earlier date or due solely as a result of actions taken by the Obligors in accordance with the covenants set forth in the Note Purchase Agreement.

4. Effectiveness; Conditions Precedent. This Amendment and the amendments to the Note Purchase Agreement provided in Sections 1 and 2 hereof shall be effective as of the date first written above upon the satisfaction of the following conditions precedent:
