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 Bristow and Era to obtain the 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; the outcome of any legal proceedings, regulatory proceedings or enforcement matters that may be instituted relating to the anticipated combination; conditions imposed on the companies in order to obtain required regulatory approvals; the costs incurred to consummate the anticipated combination; the possibility that the expected synergies or cost savings 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; 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 Bristow and Era operate or credit markets, including disruptions in the offshore oil and gas markets throughout the globe; changes in the regulatory regimes governing the offshore oil and gas markets and the offshore oil and gas services markets; the inability of Bristow or Era to execute on contracts 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 Bristow and Era, changes in industry norms and adverse outcomes in legal or other dispute resolution proceedings.

For a more complete discussion of these and other risk factors, please see each of Bristow's and Era's annual and quarterly filings with the Securities and Exchange Commission, including Era's annual report on Form 10-K for the year ended December 31, 2018, and Bristow's annual report on Form 10-K for the year ended March 31, 2019 and their respective subsequent quarterly reports on Form 10-Q. This presentation reflects the views of Bristow's management and Era's management as of the date hereof. Except to the extent required by applicable law, Bristow and Era undertake no obligation to update or revise any forward-looking statement.

Non-GAAP Financial Measures In this presentation, Era includes EBITDA (“Era EBITDA”) and Adjusted EBITDA (“Era Adjusted EBITDA”) as supplemental measures of Era’s operating performance. EBITDA is defined as Earnings before Interest (includes interest income and interest expense), Taxes, Depreciation and Amortization. Adjusted EBITDA is defined as EBITDA further adjusted for special items that occurred during the reporting period. Neither EBITDA nor Adjusted EBITDA is a recognized term under generally accepted accounting principles in the U.S. (“GAAP”). Accordingly, they should not be used as an indicator of, or an alternative to, net income as a measure of operating performance. In addition, EBITDA and Adjusted EBITDA are not intended to be measures of free cash flow available for discretionary use, as they do not take into account certain cash requirements, such as debt service requirements. EBITDA and Adjusted EBITDA have limitations as analytical tools, and you should not consider them in isolation, nor as a substitute for analysis of Era’s results as reported under GAAP. Because the definitions of EBITDA and Adjusted EBITDA (or similar measures) may vary among companies and industries, they may not be comparable to other similarly titled measures used by other companies. Era also presents net debt, which is a non-GAAP measure, defined as total principal balance on borrowings less cash and cash equivalents, including escrow balances. Each of these non-GAAP measures has limitations and therefore should not be used in isolation or as a substitute for the amounts reported in accordance with GAAP. A reconciliation of EBITDA, Adjusted EBITDA and net debt is included in this presentation. Era Free Cash Flow (“Era Free Cash Flow”) represents Era’s net cash provided by operating activities plus proceeds from disposition of property and equipment, less expenditures related to purchases of property and equipment. Era Adjusted Free Cash Flow (“Era Adjusted Free Cash Flow”) is Free Cash Flow adjusted to exclude professional services fees paid in respect of litigation settled in the third quarter of 2018 and the proceeds on settlement of that litigation. Era’s management believes that the use of Adjusted Free Cash Flow is meaningful as it measures Era’s ability to generate cash from its business after excluding cash payments for special items. Era’s management uses this information as an analytical indicator to assess Era’s liquidity and performance. However, investors should note numerous methods may exist for calculating a company's free cash flow. As a result, the method used by management to calculate Adjusted Free Cash Flow may differ from the methods used by other companies to calculate their free cash flow. In this presentation, Bristow includes adjusted EBITDA (“Bristow Adjusted EBITDA”) as a supplemental measure of operating performance, providing relevant and useful information which is widely used by analysts, investors and competitors in our industry as well as by Bristow’s management in assessing both consolidated and regional performance. Bristow Adjusted EBITDA provides Bristow with an understanding of one aspect of earnings before the impact of investing and financing transactions and income taxes. Bristow Adjusted EBITDA should not be considered a measure of discretionary cash available to Bristow for investing in the growth of their business. Bristow Adjusted EBITDA is not calculated or presented in accordance with GAAP and other companies in the industry may calculate these measures differently than Bristow does. As a result, these financial measures have limitations as analytical and comparative tools and you should not consider these measures in isolation, or as a substitute for analysis of Bristow’s results as reported under GAAP. In calculating this financial measure, Bristow makes certain adjustments that are based on assumptions and estimates that may prove to be inaccurate. In addition, in evaluating this financial measure, you should be aware that in the future Bristow may incur expenses similar to those eliminated in this presentation. Presentation of Bristow Adjusted EBITDA should not be construed as an inference that its future results will be unaffected by unusual or special items. Some of the additional limitations of Era Adjusted EBITDA and Bristow Adjusted EBITDA are: Does not reflect current or future cash requirements for capital expenditures; Does not reflect changes in, or cash requirements for, working capital needs; Does not reflect the significant interest expense or the cash requirements necessary to service interest or principal payments on debts; and Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and neither Era Adjusted EBITDA nor Bristow Adjusted EBITDA reflect any cash requirements for such replacements.
