Cautionary Statement Regarding Forward-Looking Statements

Information included or incorporated by reference in this Current Report on Form 8-K/A, and information which may be contained in other filings with the Securities and Exchange Commission (the “SEC”) and press releases or other public statements, contains or may contain, “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. The Company’s and SUPERVALU’s actual results may differ from their expectations, estimates and projections and consequently, you should not rely on these forward looking statements as predictions of future events. Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “might” and “continues,” and similar expressions are intended to identify such forward-looking statements. These forward-looking statements are based on current expectations and assumptions with respect to future performance and anticipated financial impacts of the business combination, the satisfaction of the closing conditions to the business combination and the timing of the completion of the business combination. These forward-looking statements involve significant risks and uncertainties that could cause actual results to differ materially from expected results.  Actual results could differ materially from those anticipated as a result of various factors, including: (1) the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement relating to the proposed business combination; (2) the outcome of any legal proceedings that may be instituted following the announcement of the merger agreement and the transactions contemplated therein; (3) the inability to complete the business combination, including due to failure to obtain approval of the shareholders of SUPERVALU or other conditions to closing in the merger agreement; (4) risks related to the financing of the transaction; (5) the risk that the business combination disrupts current plans and operations as a result of the announcement and consummation of the business combination; (6) the ability to recognize the anticipated benefits of the business combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably and retain its key employees; (7) costs related to the business combination; (8) risks related to the disruption of the transaction to SUPERVALU and its management; (9) the effect of announcement of the transaction on SUPERVALU’s ability to retain and hire key personnel and maintain relationships with customers, suppliers and other third parties; and (10) other risks and uncertainties identified in the Company’s and SUPERVALU’s filings with the SEC.  The foregoing review of important factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements that are included herein and elsewhere, including the Risk Factors included in the most recent reports on Form 10-K and Form 10-Q and other documents of the Company and SUPERVALU on file with the SEC.  These SEC filings are available publicly on the SEC’s website at www.sec.gov.  Any forward-looking statements made or incorporated by reference in this Current Report on Form 8-K/A are qualified in their entirety by these cautionary statements, and there can be no assurance that the anticipated results or developments will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, the Company.  Except to the extent required by applicable law, neither the Company nor SUPERVALU undertakes any obligation to update publicly or revise any forward-looking statements, whether as a result of new information, future developments or otherwise.  Given these risks and uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements.
