Safe Harbor and Forward-Looking Information This document includes forward-looking statements (which includes “forward-looking information” within the meaning of applicable Canadian securities laws). These forward-looking statements are not based on historical facts but instead reflect Progressive Waste's or Waste Connections’ respective management’s expectations, estimates or projections concerning future results or events. These forward-looking statements are often identified by the words “may,” “might,” “believes,” “thinks,” “anticipates,” “plans,” “expects,” “intends” or similar expressions and include statements regarding (1) expectations regarding whether the transaction, including the merger, the issuance of the merger consideration and the proposed share consolidation of Progressive Waste, will be consummated, including whether conditions to the consummation of the transaction will be satisfied, or the timing for completing the transaction, (2) expectations for the effects of the transaction or the ability of the combined company to successfully achieve business objectives, including integrating the companies or the effects of unexpected costs, liabilities or delays, (3) the potential benefits and synergies of the transaction, including expected cost savings and tax benefits and (4) expectations for other economic, business, and/or competitive factors. Although Waste Connections and Progressive Waste believe that the expectations reflected in such forward-looking statements are reasonable, such statements involve risks and uncertainties, and undue reliance should not be placed on such statements, as unknown or unpredictable factors could have material adverse effects on future results, performance or achievements of the combined company. Among the key factors that could cause actual results to differ materially from those projected in the forward-looking statements include the following: the ability to consummate the proposed transaction; the ability to obtain requisite regulatory and shareholder approvals and the satisfaction of other conditions to the consummation of the proposed transactions on the proposed terms and schedule; the ability of Waste Connections and Progressive Waste to successfully integrate their respective operations and employees and realize synergies and cost savings at the times, and to the extent, anticipated; the potential impact of the announcement or consummation of the proposed transactions on relationships, including with employees, suppliers, customers and competitors; changes in general economic, business and political conditions, including changes in the financial markets; changes in applicable laws; significant competition that Waste Connections and Progressive Waste face; compliance with extensive government regulation; and the diversion of management time on the proposed transactions. These forward-looking statements may be affected by risks and uncertainties in the business of Waste Connections and Progressive Waste and market conditions. This information is qualified in its entirety by cautionary statements and risk factor disclosure contained in filings made by Waste Connections and Progressive Waste with the U.S. Securities and Exchange Commission, including Waste Connections’ quarterly reports on Form 10-Q and its annual report on Form 10-K for the year ended December 31, 2014, and Progressive Waste’s quarterly reports on Form 6-K and its year-end report for the year ended December 31, 2014, as well as in Progressive Waste’s filings with the Canadian securities regulators. Waste Connections and Progressive Waste wish to caution readers that certain important factors may have affected and could in the future affect their actual results and could cause their actual results for subsequent periods to differ materially from those expressed in any forward-looking statement made by or on behalf of Waste Connections or Progressive Waste. Neither Waste Connections nor Progressive Waste undertakes any obligation to update forward-looking statements to reflect events or circumstances after the date hereof, except as may be specifically required by applicable securities laws. 2
