Mark Seed Company and Asociados Don Mario S.A. are proud to announce that they are
starting the evaluation, testing, and development of soybean seed products utilizing Mark
Seed’s patented Cyst Tech technology along with the DONMARIO germplasm for the
South American soybean market.

According to Mark Seed president Mark Terpstra, “This is a major development for
soybean producers. Farmers in both North and South America will now have greater
access to this rapidly growing technology. As a result, more bags of Cyst Tech soybean
seed will be available to the producers in the US as well as South America.”

Mark Seed Company, headquartered in Perry, Iowa, is one of the fastest growing seed
companies in the United States. Cyst Tech has been designed to control the major pest of
soybean, Soybean Cyst Nematode, and to increase yield for soybean producers. Many
soybean farmers have seen yield increases of 20% and more by using the Cyst Tech
program.

Argentina based, Asociados Don Mario S.A. is one of the largest soybean seed producers
in South America, selling nearly 30% of soybean seed in the region. By gaining access to
this technology Don Mario will continue to be at the forefront of the industry and deliver
the best products to their customers.

With the growing world population, the need for soybean oil and protein will greatly
increase over the coming years. Cyst Tech technology will be there to help to feed the
world.

Mark Seed Company grows, conditions and distributes seed throughout North America,
specializing in Soybeans. The Company was founded in 1985 by Mark Terpstra, a third
generation seeds man.
