White Wave, Horizon Organic and Dean National Brand Group Will Be Consolidated

               and Headquartered in the Boulder, Colorado Area

      Steve Demos to Serve as President of Newly Consolidated Businesses

DALLAS, Aug. 4 /PRNewswire-FirstCall/ — Dean Foods Company (NYSE: DF)
today announced plans to consolidate its three branded businesses: White Wave,
Horizon Organic and the Dean National Brand Group. The newly combined
operation will be headquartered in the Boulder, Colo. area and is expected to
have 2004 revenue of approximately $1.1 billion. The change is intended to
enable the consolidated company to capture the full potential of its rapidly
growing brands, to better serve its customers, leverage its scale, and
increase profitability over time. Steve Demos, founder and president of White
Wave, will serve as president of the newly consolidated company, and will
continue to report to Gregg Engles, chairman and chief executive officer of
Dean Foods. The consolidation is anticipated to be complete by late 2005.

“We possess a strong stable of national brands with very high growth
rates,” said Engles. “Our current structure, with three distinct
organizations, including three sales forces and three separate supply chains,
is not the right structure to tap the full potential of our brands. This new
organization will allow us to streamline and simplify our business model, and
is the right design to drive our business forward.

“In addition to allowing us to leverage our scale and increase
profitability, combining the three businesses will enable us to increase our
investment in marketing and innovation,” continued Engles. “We also have
significant opportunity to improve our go-to-market strategy, given the common
customer bases of our branded businesses. Over time, we will simplify our
supply chain with plants dedicated to the manufacture of our branded products.

“We remain committed to driving increased shareholder value. These
changes will lead to a stronger, purpose-driven organization, capable of
capturing the tremendous opportunities ahead,” Engles concluded.

Steve Demos founded White Wave in 1977, growing the company to nearly
$300 million in revenue in 2003. As founder and president, he has been
responsible for the strategic direction and operations of White Wave. Demos
joined the Dean Foods organization following its acquisition of White Wave in
May 2002. “Steve is a visionary business leader with unmatched passion,
energy and commitment to creating a compelling and sustainable business,” said
Engles. “Steve is highly respected within the natural and organic foods
industry. He has exceptional experience in building the Silk brand that can
now be applied to our strong portfolio of high growth brands.”

In accepting his new position, Demos said, “By combining these three fine
companies, we are creating a business with $1.1 billion in annual sales,
growing over 20% per year. We sell innovative, authentic and nutritious
products under strong brands. We own the largest and most dynamic natural and
organic brands in the United States: Silk and Horizon Organic. We have a
heritage of corporate and environmental stewardship that is part of the fabric
of our culture and that we intend to build upon. And we have great people who
have helped create these brands and for whom this new organization will create
wonderful opportunities. I could not be more pleased to lead this new
organization, nor more excited about the opportunity.”

Chuck Marcy, president of Horizon Organic, will assist in the integration
of the three businesses and will remain with the company through January 2005.
“We greatly appreciate Chuck’s efforts to further Horizon Organic and the
organic foods industry as a whole. We are fortunate to have his leadership
during this transition period,” Engles said. “Under Chuck’s leadership,
Horizon Organic has become the nation’s leading dedicated organic food brand.
Since our acquisition of the company, the brand’s growth has accelerated,
reconfirming our belief that the Horizon Organic brand continues to have great
growth prospects.”

The consolidated company’s brand portfolio consists of Silk(R) and Sun
Soy(R) soymilk, Horizon Organic(R) branded products, International Delight(R)
coffee creamers, Hershey’s(R) milks and milkshakes, Land O’Lakes(R) milk and
