Dear Minn-Dak Stockholder/Grower:

We are writing to inform you of an important decision made by your Board of
Directors at its meeting on Tuesday, April 22, 2003.

Your Board of Directors has approved the sale of Minn-Dak's 5% ownership
interest in ProGold LLC to American Crystal Sugar Company, Moorhead, Minnesota
for a sales price of $10.3 million. Following the close of this sale, American
Crystal Sugar Company will have a 51% ownership interest in ProGold and Golden
Growers Cooperative will continue to own 49%.

The Minn-Dak Board of Directors concluded the investment in ProGold no longer
played a key role in your co-op's strategic direction, so offers to purchase our
ownership position were solicited. Minn-Dak's strategic plan calls for
continuing focus on our core business, that being the production of quality
sugar and co-products. Our attention will continue to be directed at further
improving the efficiencies of our operations and managing the organization
through significant changes in our industry and the business environment in
which we operate.

We realize many of you are Golden Growers members. Minn-Dak is pleased that we
played a role in getting the ProGold plant built. Our participation and $5.2
million investment helped provide the opportunity for Minn-Dak's
stockholder/growers as well as other area farmers to be part of a value added
business. That was one of the underlying reasons in working with the team that
promoted and built the ProGold plant in 1995. We remained on board while the
ProGold operation moved through its early years of operation. Today that plant
is very efficient by industry standards and able to produce a quality product
for the marketplace. ProGold members continue to benefit by having that added
nearby market for their corn.

We look forward to the continued success of the ProGold operation.

Sincerely,

/s/ Victor Krabbenhoft                               /s/ David H.Roche
