Caution Concerning Forward Looking Statements

Statements that are not historical in nature constitute forward looking statements. These forward-looking statements relate to information or assumptions about the timing of completion of the proposed acquisition, the expected benefits of the proposed acquisition, management’s plans, projections and objectives for future operations, scale and performance, integration plans and expected synergies therefrom, and anticipated future financial and operating performance results, including operating margin or gross margin capital and other expenditures, cash flow, dividends, restructuring and other project costs, costs and cost savings, and debt ratings. These statements are accompanied by words such as “anticipate,” “expect,” “project,” “will,” “believe,” “estimate” and similar expressions. Such expectations are based upon certain preliminary information, internal estimates, and management assumptions, expectations, and plans, and are subject to a number of risks and uncertainties inherent in projecting future conditions, events, and results. Actual results could differ materially from those expressed or implied in the forward-looking statements if one or more of the underlying assumptions or expectations prove to be inaccurate or are unrealized. Important factors that could cause actual results to differ materially from those suggested by the forward-looking statements include, but are not limited to, the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement; the risk that the necessary shareholder approvals may not be obtained; the risk that the necessary regulatory approvals may not be obtained or may be obtained subject to conditions that are not anticipated; the risk that the proposed acquisition will not be consummated in a timely manner; risks that any of the closing conditions to the proposed acquisition may not be satisfied or may not be satisfied in a timely manner; risks related to disruption of management time from ongoing business operations due to the proposed acquisition; failure to realize the benefits expected from the proposed acquisition; failure to promptly and effectively integrate the acquisition; and the effect of the announcement of the proposed acquisition on the ability of Jarden to retain customers and retain and hire key personnel, maintain relationships with suppliers, on Jarden’s operating results and businesses generally and those factors listed in Jarden’s most recently filed Quarterly Report on Form 10-Q and Exhibit 99.1 thereto and Jarden’s most recent Annual Report on Form 10-K for the year ended December 31, 2014, in each case, filed with the Securities and Exchange Commission (“SEC”). Changes in such assumptions or factors could produce significantly different results. The information contained in this Current Report on Form 8-K is as of the date hereof.
