Colleagues,

Our combination planning effort with CB&I is well underway and we have already achieved several significant milestones.

Recently, senior leaders from both McDermott and CB&I came together for the first time at our Houston headquarters to discuss our transition to a premier, fully integrated EPCI company. The full-day planning meeting went well and we were happy to hear so many excellent and constructive ideas being discussed for our future together.

We also achieved two significant milestones critical to the approval of the combination.

On January 24, we were notified that the Federal Trade Commission granted early termination of the waiting period under the Hart-Scott-Rodino (HSR) Antitrust Improvements Act for the proposed combination. By waiving the waiting period, the government is essentially giving us a “green light” to proceed – a good sign as we clear a major hurdle ahead of schedule.

Second, we filed a Form S-4 Registration Statement with the Securities and Exchange Commission (SEC). The SEC requires publicly traded companies to file an S4 in connection with a transaction such as the proposed combination with CB&I. At 496 pages, the S-4 provides a wealth of information that shareholders of both companies will use to inform their decision about the combination. The SEC will review the S-4 and provide questions or requests for more information, which we will address as quickly as possible. We are tracking the progress closely and will share updates when appropriate.

We’re excited about the progress we’ve made toward closing the transaction, but there is still a lot of work to do before our combination can be completed. This week, the integration planning teams from both companies will meet again for three days of detailed planning sessions. We will report back to you after those meetings with feedback.

Thank you for your continued hard work and support. Stay focused on our daily business. We’ll keep you updated as we move forward.

Additional Information and Where to Find It

This communication is for information purposes only and does not constitute an offer to sell or the solicitation of an offer to buy any securities or a solicitation of any proxy, vote or approval with respect to the proposed transaction or otherwise, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. In connection with the proposed transactions, on January 24, 2018, McDermott International, Inc. (“McDermott”) filed a Registration Statement on Form S-4 with the U.S. Securities and Exchange Commission (the “SEC”), that included (1) a joint proxy statement of McDermott and Chicago Bridge & Iron Company N.V. (“CB&I”), which also constitutes a prospectus of McDermott and (2) an offering prospectus of McDermott Technology, B.V. to be used in connection with McDermott Technology, B.V.’s offer to acquire CB&I shares. After the registration statement is declared effective by the SEC, McDermott and CB&I intend to mail a definitive joint proxy statement/prospectus to stockholders of McDermott and shareholders of CB&I. McDermott or McDermott Technology, B.V. intends to file a Tender Offer Statement on Schedule TO (the “Schedule TO”) with the SEC and soon thereafter CB&I intends to file a Solicitation/Recommendation Statement on Schedule 14D-9 (the “Schedule 14D-9”) with respect to the exchange offer. The exchange offer for the outstanding common stock of CB&I referred to in this document has not yet commenced. The solicitation and offer to purchase shares of CB&I’s common stock will only be made pursuant to the Schedule TO and related offer to purchase. This material is not a substitute for the joint proxy statement/prospectus, the Schedule TO, the Schedule 14D-9 or the Registration Statement or for any other document that McDermott or CB&I may file with the SEC and send to McDermott’s and/or CB&I’s shareholders in connection with the proposed transactions. BEFORE MAKING ANY VOTING OR INVESTMENT DECISION OR DECISION WITH RESPECT TO THE EXCHANGE OFFER, WE URGE INVESTORS OF CB&I AND MCDERMOTT TO READ THE REGISTRATION STATEMENT, JOINT PROXY STATEMENT/PROSPECTUS, SCHEDULE TO (INCLUDING AN OFFER TO PURCHASE, RELATED LETTER OF TRANSMITTAL AND OTHER OFFER DOCUMENTS) AND SCHEDULE 14D-9, AS EACH MAY BE AMENDED OR SUPPLEMENTED FROM TIME TO TIME, AND OTHER RELEVANT DOCUMENTS FILED BY MCDERMOTT AND CB&I WITH THE SEC CAREFULLY WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT MCDERMOTT, CB&I AND THE PROPOSED TRANSACTIONS.
