MORNINGSTAR FOODS

Transaction to Occur as Part of Dean Foods Company Sale of Morningstar Division to Saputo Inc.

DALLAS, December 3, 2012 – The WhiteWave Foods Company (the “Company”) (NYSE: WWAV) today announced that it had agreed to sell certain assets owned by the Company to Morningstar Foods for $60 million, net of taxes, in connection with the separately announced sale by Dean Foods Company of its Morningstar business to Saputo Inc.

The Company has agreed to terminate an option to purchase plant capacity and property at a Morningstar facility in Frederick, Md. The Company has also agreed to sell manufacturing equipment used to produce certain WhiteWave products located at the Morningstar Sulphur Springs, Texas, plant to Morningstar. WhiteWave and Morningstar will continue their long-standing commercial relationship in which Morningstar manufactures certain products for the Company with the equipment being sold. This sale is not expected to change the economic terms of the Company’s co-packing arrangement with Morningstar.

In addition, the Company and Morningstar have agreed to modify certain terms of existing intercompany commercial agreements between the two companies. These modifications are not expected to have a material effect on the Company.

WhiteWave will continue its business relationship with Saputo Inc. pursuant to which Saputo manufactures and sells WhiteWave products in Canada.

“WhiteWave is pleased to continue its relationship with Morningstar, which will soon become part of the Saputo organization, said Gregg Engles, Chairman and CEO of The WhiteWave Foods Company. “We will use the net proceeds of $60 million after taxes to reduce outstanding debt, which will in turn allow us greater flexibility to continue to pursue our strategic growth plans.”
