FORWARD LOOKING STATEMENTS McDermott and CB&I caution that statements in this presentation which are forward-looking, and provide other than historical information, involve risks, contingencies and uncertainties that may impact actual results of operations of McDermott, CB&I and the combined company. These forward-looking statements include, among other things, statements about anticipated cost and revenue synergies, accretion, best-in-class operations, opportunities to capture additional value from market trends, maintenance of a consistent customer approach to pricing, safety and transition issues, free cash flow, plans to de-lever, targeted credit ratings, expected completion date, accretion and permanent debt financing. Although we believe that the expectations reflected in those forward-looking statements are reasonable, we can give no assurance that those expectations will prove to have been correct. Those statements are made by using various underlying assumptions and are subject to numerous risks, contingencies and uncertainties, including, among others: the ability of McDermott and CB&I to obtain the regulatory and shareholder approvals necessary to complete the anticipated combination, on the anticipated timeline or at all; the risk that a condition to the closing of the anticipated combination may not be satisfied, on the anticipated timeline or at all or that the anticipated combination may fail to close, including as the result of any inability to obtain the financing for the combination; the outcome of any legal proceedings, regulatory proceedings or enforcement matters that may be instituted relating to the anticipated combination; the costs incurred to consummate the anticipated combination; the possibility that the expected synergies from the anticipated combination will not be realized, or will not be realized within the expected time period; difficulties related to the integration of the two companies; the credit ratings of the combined company following the anticipated combination; disruption from the anticipated combination making it more difficult to maintain relationships with customers, employees, regulators or suppliers; the diversion of management time and attention on the anticipated combination; adverse changes in the markets in which McDermott and CB&I operate or credit markets; the inability of McDermott or CB&I to execute on contracts in backlog successfully; changes in project design or schedules; the availability of qualified personnel; changes in the terms; scope or timing of contracts; contract cancellations; change orders and other modifications and actions by customers and other business counterparties of McDermott and CB&I; changes in industry norms; and adverse outcomes in legal or other dispute resolution proceedings. If one or more of these risks materialize, or if underlying assumptions prove incorrect, actual results may vary materially from those expected. You should not place undue reliance on forward-looking statements. For a more complete discussion of these and other risk factors, please see each of McDermott’s and CB&I’s annual and quarterly filings with the Securities and Exchange Commission, including their annual reports on Form 10-K for the year ended December 31, 2016 and subsequent quarterly reports on Form 10-Q.

Except to the extent required by applicable law, McDermott and CB&I undertake no obligation to update or revise any forward-looking statement.

NON-GAAP DISCLOSURES This presentation includes several “non-GAAP” financial measures as defined under Regulation G of the U.S. Securities Exchange Act of 1934, as amended. Each of McDermott and CB&I reports its financial results in accordance with U.S. generally accepted accounting principles, but McDermott and CB&I believe that certain non-GAAP financial measures provide useful supplemental information to investors regarding the underlying business trends and performance of their respective ongoing operations and are useful for period-over-period comparisons of those operations. The non-GAAP measures in this presentation include EBITDA, Adjusted EBITDA and Adjusted Net Income. These non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, the financial measures prepared in accordance with GAAP. Reconciliations of these non-GAAP financial measures to the most comparable GAAP measures are provided on pages 27, 28, 29 and 30 of this presentation.

FINANCIAL APPENDIX

MCDERMOTT NON-GAAP RECONCILIATIONS6 1Restructuring charges were primarily associated with personnel reductions, facility closures, consultant fees, lease terminations and asset impairments. 2The 10.9 million of impairment that was recognized in the fourth quarter of 2016 is primarily related to impairment of drydock costs of the I-600 vessel. 3$5.4 million in gain was recorded in the quarter ended December 31, 2016, as a result of the non-cash actuarial mark-to-market adjustment recorded in the fourth quarter of each year. 4The adjustments to GAAP Net Income have been income tax effected when included in net income. Tax effects of Non-GAAP adjustments represent the tax impacts of the adjustments during the period. Some Non-GAAP adjusting items are primarily attributable to tax jurisdictions in which the Company, currently, does not pay taxes and, therefore, no tax impact is applied to them. For the Non-GAAP adjusting items in jurisdictions where taxes are paid, the tax impacts on those adjustments are computed, individually, using the statutory tax rate in effect in each applicable taxable jurisdiction. 5EBITDA is defined as net income plus depreciation and amortization, interest expense, net and provision for income taxes. Adjusted EBITDA is defined as EBITDA less the adjustments relating to restructuring charges, impairment loss and gain/loss on pension as detailed in footnotes 1, 2 and 3. We have included EBITDA and Adjusted EBITDA disclosures in this supplemental deck because EBITDA is widely used by investors for valuation and comparing financial performance with the performance of other companies in the industry and because Adjusted EBITDA provides a consistent measure of EBITDA relating to the underlying business. McDermott management also uses EBITDA and Adjusted EBITDA to monitor and compare the financial performance of the operations. EBITDA and Adjusted EBITDA do not give effect to the cash that must be used to service debt or pay income taxes, and thus do not reflect the funds actually available for capital expenditures, dividends or various other purposes. In addition, the presentation of EBITDA and Adjusted EBITDA may not be comparable to similarly titled measures in other companies’ reports. You should not consider EBITDA or Adjusted EBITDA in isolation from, or as a substitute for, net income or cash flow measures prepared in accordance with U.S. GAAP. 6Sum of components may not fit due to rounding.   Three Months Ended Nine Months Ended Last Twelve Months   Dec 31, 2016 Sept 30, 2017 Sept 30, 2017 (Dollars In millions)               GAAP Net Income (Loss) Attributable to McDermott $(0.5) $153 $153         Plus: Non-GAAP Adjustments       Restructuring Charges1 1 - 1 Impairment Loss2 11 - 11 Non-Cash Acturial Loss (Gain) on Benefit Plans3 (5) - (5) Total Non-GAAP Adjustments 6 - 6 Tax Effect of Non-GAAP Changes4 0 - - Total Non-GAAP Adjustments (After Tax) 6 - 6 Non-GAAP Adjusted Net Income Attributable to McDermott 6 153 159         GAAP Net Income (Loss) Attributable to McDermott $(0.5) $153 $153 Add:       Depreciation & Amortization 26 78 104 Interest Expense, Net 18 51 69 Provision for Income Taxes (13) 53 40 EBITDA5 $29.8 $335.2 $365         EBITDA $30 $335 $365 Plus: Non-GAAP Adjustments 6 - 6 Non-GAAP Adjusted EBITDA5 $35.9 $335.2 $371

CB&I NON-GAAP RECONCILIATIONS 1Represents historically reported financial information, adjusted for the exclusion of the Capital Services segment which was sold in Q2 2017 and inclusion of the Technology and Engineered Products operations, which were presented as discontinued operations beginning Q3 2017. A reconciliation of CB&I's reported financial results with the continuing base company is provided on slide 26. 2Represents a charge recorded in the fourth quarter 2016 related to the establishment of a reserve for the Transaction Receivable associated with the sale of CB&I’s former nuclear operations on December 31, 2015. 3Represents the net impact of significant changes in estimates on projects during the period, primarily related to charges on two U.S. gas turbine power projects and two U.S. LNG export facility projects, partially offset by the benefit of increased recoveries on two cost reimbursable projects. The U.S. gas turbine power projects were negatively impacted by lower than anticipated craft labor productivity; slower than anticipated benefits from mitigation plans; and extensions of schedule and related prolongation costs (including schedule related liquidated damages). A majority of the impacts for the US LNG projects were related to a project in Hackberry LA, which was impacted primarily by lower than anticipated craft labor productivity; weather related delays; increased material, construction and fabrication costs due to quantity growth and material delivery delays; higher than anticipated estimates from subcontractors for their work scopes; and extensions of schedule and related prolongation costs resulting from the aforementioned. The remaining impacts for the US LNG projects related to a project in Freeport, TX which was impacted primarily by increased material, construction and fabrication costs due to quantity growth and material delivery delays, weather related delays; and potential extensions of schedule and related prolongation costs resulting from the aforementioned. 4Represents costs primarily associated with facility realignment, severance and professional services resulting from publicly announced cost reduction and strategic initiatives. 5Represents accelerated amortization of debt issuance costs resulting from the agreement with creditors to use the proceeds from the sale of Technology Operations to repay outstanding debt. 6The adjustments to GAAP Net Income have been income tax effected when included in net income. Tax effects of Non-GAAP adjustments represent the estimated tax impacts of the adjustments during the period. 7EBITDA is defined as net income plus depreciation and amortization, interest expense, net and provision for income taxes. Adjusted EBITDA is defined as EBITDA less the adjustments relating to the receivable reserve from the sale of the nuclear operations, significant project charges, restructuring charges and accelerated amortization of debt issuance costs as detailed in footnotes 2, 3, 4 and 5. We have included EBITDA and Adjusted EBITDA disclosures in this supplemental deck because EBITDA is widely used by investors for valuation and comparing financial performance with the performance of other companies in the industry and because Adjusted EBITDA provides a consistent measure of EBITDA relating to the underlying business. McDermott management also uses EBITDA and Adjusted EBITDA to monitor and compare the financial performance of the operations. EBITDA and Adjusted EBITDA do not give effect to the cash that must be used to service debt or pay income taxes, and, thus, do not reflect the funds actually available for capital expenditures, dividends or various other purposes. In addition, the presentation of EBITDA and Adjusted EBITDA may not be comparable to similarly titled measures in other companies’ reports.

As CB&I does not report net income by segment, we have alternatively calculated EBITDA as operating income (loss) plus noncontrolling interest and depreciation and amortization. Adjusted EBITDA is defined as EBITDA less the non-GAAP adjustments detailed in footnotes 5 and 6. 5Represents a charge recorded in the fourth quarter 2016 related to the establishment of a reserve for the Transaction Receivable associated with the sale of CB&I’s former nuclear operations on December 31, 2015. 6Represents the net impact of significant changes in estimates on projects during the period, primarily related to charges on two U.S. gas turbine power projects and two U.S. LNG export facility projects, partially offset by the benefit of increased recoveries on two cost reimbursable projects. The U.S. gas turbine power projects were negatively impacted by lower than anticipated craft labor productivity; slower than anticipated benefits from mitigation plans; and extensions of schedule and related prolongation costs (including schedule related liquidated damages).A majority of the impacts for the U.S. LNG projects were related to a project in Hackberry LA, which was impacted primarily by lower than anticipated craft labor productivity; weather related delays; increased material, construction and fabrication costs due to quantity growth and material delivery delays; higher than anticipated estimates from subcontractors for their work scopes; and extensions of schedule and related prolongation costs resulting from the aforementioned. The remaining impacts for the U.S. LNG projects related to a project in Freeport, TX which was impacted primarily by increased material, construction and fabrication costs due to quantity growth and material delivery delays; weather related delays; and potential extensions of schedule and related prolongation costs resulting from the aforementioned. 7Restructuring costs are primarily associated with facility realignment, severance and professional services resulting from publicly announced cost reduction and strategic initiatives. 8Sum of components may not foot due to rounding.   Three Months Ended Nine Months Ended Last Twelve Months   Dec 31, 2016 Sept 30, 2017 Sept 30, 2017   E&C FS Tech CS Total E&C FS Tech CS Res Total E&C FS Tech CS Res Total (Dollars In millions)                                                                       Operating Income (Loss), as reported2 $(183) $22 $28 $(637) $(769) $(506) $98 $ - $ - $(31) $(439) $(689) $120 $28 $(637) $(31) $(1,209) Less: Reclassification of Discontinued Operations and Adjustments3 (3) (2) - 637 632 3 69 73 - - 145 (0) 67 73 637 - 777 Operating Income (Loss), on a continuing operations basis $(186) $20 $28 $ - $(138) $(503) $166 $73 $ - $(31) $(294) $(689) $187 $101 $ - $(31) $(432)                                     Plus: Operating Income (Loss) Attributable to Noncontrolling Interests (4) - - (1) (5) (29) (2) - (1) - (32) (33) (2) - (2) - (37) Plus: Depreciation & Amortization 3 13 6 7 29 8 37 17 4 - 66 11 50 23 11 - 95 Less: Reclassification of Discontinued Operations and Adjustments3 - - - (6) (6) - - - (3) - (3) - - - (9) - (9) EBITDA4 $(187) $33 $34 $ - $(120) $(524) $201 $90 $ - $(31) $(263) $(711) $235 $124 $ - $(31) $(383)                                     Plus: Non-GAAP Adjustments                                   Receivable Reserve from Sale of Nuclear Operations5 148 - - - 148 - - - - - - 148 - - - - 148 Significant Project Charges6 153 52 - - 205 641 - - - - 641 794 52 - - - 846 Restructuring Costs7 - - - - - - - - - 31 31 - - - - 31 31 Non-GAAP Adjusted EBITDA4 $114 $85 $34 $ - $233 $117 $201 $90 $ - $ - $409 $231 $287 $124 $ - $ - $642 Non-GAAP Adjusted EBITDA as percent of total                       36% 45% 19% 0% 0% 100%
