SAFE HARBOR STATEMENT

Forward Looking Statements

Some of the statements in this document are forward-looking statements (or forward-looking information) within the meaning of applicable U.S. and Canadian securities laws. These include statements using the words target, outlook, may, will, should, could, estimate, continue, expect, intend, plan, predict, potential, project and anticipate, and similar statements which do not describe the present or provide information about the past. There is no guarantee that the expected events or expected results will actually occur. Such statements reflect the current views of management of Mitel and Aastra and are subject to a number of risks and uncertainties. These statements are based on many assumptions and factors, including general economic and market conditions, industry conditions, corporate approvals, regulatory approvals, operational factors and other factors. Any changes in such assumptions or factors could cause actual results to differ materially from current expectations. All forward-looking statements attributable to Mitel and Aastra, or persons acting on their behalf, and are expressly qualified in their entirety by the cautionary statements set forth in this paragraph. Undue reliance should not be placed on such statements. Forward-looking statements speak only as of the date they are made. In addition, material risks that could cause results of operations to differ include the merged company’s ability to achieve or sustain profitability in the future; fluctuations in the quarterly and annual revenues and operating results; fluctuations in foreign exchange rates; current and ongoing global economic instability; intense competition; reliance on channel partners for a significant component of sales; dependence upon a small number of outside contract manufacturers to manufacture products; the ability to successfully integrate the acquisition and realize certain synergies; and, our ability to implement and achieve our business strategies successfully. Additional risks are described under the heading “Risk Factors” in Mitel’s Annual Report on Form 10-K and Aastra’s Annual Information Form. Except as required by law, we do not have any intention or obligation to update or to publicly announce the results of any revisions to any of the forward-looking statements to reflect actual results, future events or developments, changes in assumptions or changes in other factors affecting the forward-looking statements. You are advised, however, to consult any further public disclosures made by Mitel and Aastra on related subjects in reports and communications filed on Electronic Data-Gathering, Analysis, and Retrieval (EDGAR) or System for Electronic Document Analysis and Retrieval (SEDAR).

Non-GAAP Financial Measurements

This presentation includes references to non-GAAP financial measures including adjusted EBITDA, non-GAAP income and non-GAAP operating expenses. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similar measures presented by other companies. We use these non-GAAP financial measures to assist management and investors in understanding our past financial performance and prospects for the future, including changes in our operating results, trends and marketplace performance, exclusive of unusual events or factors which do not directly affect what we consider to be our core operating performance. Non-GAAP measures are among the primary indicators management uses as a basis for our planning and forecasting of future periods. Investors are cautioned that non-GAAP financial measures should not be relied upon as a substitute for financial measures prepared in accordance with generally accepted accounting principles. Please see the reconciliation of non-GAAP financial measures to the most directly comparable U.S. GAAP measure included in this presentation and, if not contained in this presentation, contained in Mitel’s Reports on Form 8-K which have been filed with the 2 U.S. Securities and Exchange Commission on June 24, 2013 (fiscal 2013) and August 29, 2013 (Q1 of fiscal 2014).
