Factors that could cause actual results of Brookfield Infrastructure to differ materially from those contemplated or implied by the statements in this presentation include general economic conditions in the jurisdictions in which we operate and elsewhere which may impact the markets for our products and services, the ability to achieve growth within Brookfield Infrastructure’s businesses and in particular completion on time and on budget of various large capital projects, which themselves depend on access to capital and continuing favourable commodity prices, and our ability to achieve the milestones necessary to deliver the targeted returns to our unitholders, the impact of market conditions on our businesses, the fact that success of Brookfield Infrastructure is dependent on market demand for an infrastructure company, which is unknown, the availability of equity and debt financing for Brookfield Infrastructure, the ability to effectively complete new acquisitions in the competitive infrastructure space (including the ability to complete announced and potential acquisitions that may be subject to conditions precedent, and the inability to reach final agreement with counterparties to transactions referred to in this presentation as being currently pursued, given that there can be no assurance that any such transaction will be agreed to or completed) and to integrate acquisitions into existing operations, the future performance of these acquisitions, the market conditions of key commodities, the price, supply or demand for which can have a significant impact upon the financial and operating performance of our business and other risks and factors described in the documents filed by Brookfield Infrastructure with the securities regulators in Canada and the United States including under “Risk Factors” in the Partnership’s most recent Annual Report on Form 20-F and the prospectus for the offering to which this presentation relates and other risks and factors that are described therein.

Important Notice (cont’d) IMPORTANT NOTE REGARDING NON-IFRS FINANCIAL MEASURES To measure performance we focus on net income as well as funds from operations (“FFO”), FFO per unit, adjusted funds from operations (“AFFO”), adjusted EBITDA, and invested capital, which we refer to throughout this presentation. We define FFO as net income excluding the impact of depreciation and amortization, deferred income taxes, breakage and transaction costs, and non-cash valuation gains or losses. We define AFFO as FFO less capital expenditures required to maintain the current performance of our operations (maintenance capital expenditures). We define adjusted EBITDA as net income excluding the impact of depreciation and amortization, interest expense, current and deferred income taxes, breakage and transaction costs and non-cash valuation gains or losses. We define invested capital as partnership capital removing the following items: non-controlling interest in operating subsidiaries, retained earnings or deficit, accumulated other comprehensive income and ownership changes. We measure return on invested capital as AFFO, less estimated returns of capital on operations that are not perpetual in life, divided by the weighted average invested capital for the period. These measures are not calculated in accordance with, and do not have any standardized meaning prescribed by, International Financial Reporting Standards (“IFRS”) and therefore are unlikely to be comparable to similar measures presented by other issuers and have limitations as analytical tools. See the Reconciliation of Non-IFRS Financial Measures in the Appendix to this presentation, as well as reconciliations in the Partnership’s most recent Annual Report on Form 20-F and the Partnership’s most recent interim report for more information on certain of these measures, including reconciliations to the most directly comparable IFRS measures. COMPARABLES Page 5 of this presentation contains comparables regarding the Standard & Poor’s 500 Index (the “S&P 500 Index”), the Standard & Poor’s S&P/TSX Composite Index (the “S&P/TSX Composite Index”), the Standard & Poor’s 500 Utilities Index (the “S&P Utilities Index”), the Standard & Poor’s S&P/TSX Capped Utilities Index (the “S&P/TSX Capped Utilities Index”), the Alerian Master Limited Partnerships Index (the “Alerian MLP Index”) and the Dow Jones Brookfield Infrastructure Index (“DJB Infrastructure Index”) (collectively, “Comparables”). The Comparables are considered to be an appropriate basis for comparison with the Partnership because these are the key benchmarks the Partnership compares itself against. The information relating to the Comparables has been obtained or derived from public sources, and has not been verified by Brookfield Infrastructure or the investment dealers attending this presentation. Investors will not be entitled to a remedy under applicable Canadian securities legislation in the event that the Comparables contain a misrepresentation.
