Some of the statements in this document are “forward-looking” and are made pursuant to the safe harbor provision of the Securities Litigation Reform Act of 1995. These “forward-looking” statements include statements relating to (1) the impact the companies expect the proposed transaction to have on earnings per share, (2) the companies’ expectations about their ability to successfully integrate the combined businesses, (3) the amount of cost savings and overall operational efficiencies the companies expect to realize as a result of the proposed transaction, (4) when the companies expect to close the proposed transaction, (5) the level of divestitures necessary to obtain regulatory approval, (6) the companies’ projected combined sales, EBITDA and margins, (7) the ability of the companies to implement and continue branding initiatives and product innovations in a cost effective manner, (8) the ability of the companies to obtain financing for the transaction upon the terms contemplated, and (9) the ability to meet their stated financial goals. These statements involve risks and uncertainties which may cause results to differ materially from those set forth in these statements. The ability to achieve the earnings per share projected and to realize projected cost savings and operational efficiencies is dependent upon their ability in the time periods projected, to (i) consolidate or reduce certain administrative or centralized functions, (ii) obtain certain goods and services more cost effectively, (iii) shift production and distribution between operating locations without disruption in their operations or in their relations with their customers, and (iv) close the proposed transactions on the terms contemplated. The ability to close the proposed transaction in the third quarter is subject to receipt of shareholder approval and regulatory approval. The level of divestitures necessary to obtain regulatory approval of the transaction is subject to the extent of competition in the various markets in which the combining companies operate, as determined by the Department of Justice, other regulatory authorities and potentially, state and federal courts. The ability of the companies to achieve projected combined sales, EBITDA and margins is dependent upon the ability of the combining companies to maintain their existing customer and other business relationships or to replace such customers or business relationships with other comparable relationships and upon economic, governmental and competitive conditions generally. The ability of the companies to obtain financing and the terms of such financing is subject to the financial condition and operating performance of each of the combining companies prior to closing and to economic and financial market conditions generally. Other risks affecting the business of the companies are identified in their filings with the Securities and Exchange Commission, including the Suiza Foods Annual Report on Form 10-K for the year ended December 31, 2000 and the Dean Foods Annual Report on Form 10-K for the year ended May 28, 2000. All forward-looking statements in this press release speak only as of the date hereof. Suiza and Dean Foods expressly disclaim any obligation or undertaking to release publicly any updates or revisions to any such statements to reflect any change in their expectations or any changes in the events, conditions or circumstances on which any such statement is based.
