                   SUIZA FOODS AND DEAN FOODS COMPLETE MERGER

          Combination Creates Dairy Processing and Distribution Leader
 Servicing Over 150,000 Customers Coast-to-Coast Via More Than 6,000 DSD Routes

         Merged Company Will Be Named Dean Foods Company (NYSE: DF) and
             Will Have Annual Revenues of Approximately $10 Billion


         DALLAS and FRANKLIN PARK, Ill., December 21, 2001 - Suiza Foods
Corporation (NYSE: SZA) and Dean Foods Company (NYSE: DF) today completed their
merger that was announced on April 5, 2001. The combined company, to be called
Dean Foods, will have approximately $10 billion in annual revenues and will be
the nation's leading processor and distributor of fresh milk and other dairy
products and a leader in the specialty foods industry. With operations in 39
states, the combined company will have a total of 129 plants and will service
more than 150,000 customers coast-to-coast via a direct-store-delivery system of
more than 6,000 routes. Dean Foods will be headquartered in Dallas, and the
combined company will trade as DF on the New York Stock Exchange effective
Monday, December 24, 2001. The company's fiscal year end will be December 31.

         "We are extremely pleased to have completed the merger, and we will be
intently focused on integrating the companies in 2002, bringing together our
complementary operations quickly and delivering on the promise of this merger
for our customers, shareholders and employees," said Gregg Engles, Dean Foods
Chief Executive Officer. "We are committed to providing our customers with the
best possible products and services, our shareholders with enhanced value and
our employees with greater growth opportunities."




         "The merger is an important step in our company's history," said Howard
Dean, Chairman of the Board of Dean Foods. "We are very excited about the
prospects for the combined company, and I am grateful to all of the individuals
who have helped make this combination a reality."

         Upon closing, legacy Dean Foods shareholders will receive $21.00 in
cash and 0.429 shares of the new Dean Foods Company for each share owned.

         In connection with the merger, the company repurchased its 33.8% stake
in Suiza Dairy Group that was owned by Dairy Farmers of America, Inc. (DFA) for
approximately $145 million in cash, the ownership of 11 plants and a $40 million
contingent note. As a result of this transaction, all of Dean Foods' dairy
operations are now 100% owned by the company's shareholders.

         Simultaneously with the closing, the merged company replaced former
credit facilities and closed and funded a new credit facility with borrowing
capacity of up to $2.7 billion, approximately $1.9 billion of which was borrowed
at closing. An $800 million revolver remained undrawn and will be used for
general corporate purposes and future acquisitions.

         A conference call to discuss the merger and the new company's outlook
for 2002 will be held at 10:00 a.m. EST on Thursday, January 10, 2002.
