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.
