Koch Nitrogen Company, LLC Adding New Control Center at Enid Plant

July 14, 2010

Koch Nitrogen Company, LLC today broke ground on a multimillion dollar control center at
its fertilizer plant here. This is the first of several planned capital projects at the largest fertilizer plant
owned by Koch Nitrogen Company.

Today is a very exciting day for our company, as this new control center will allow us to take a more
streamlined approach to our business,” said Steve Packebush, president of Koch Nitrogen. “However, it
is important to note that this new control center is a cornerstone for our future plans, a first step to lead
the way for an additional $20 million-plus in capital expenditures in the coming years.”

The new control center will allow the various plant units and employees to better communicate by
combining three separate control rooms into one. The new control room, which is expected to be fully
operational in 2012, will allow the plant facility to be fully automated.

“By adding this control center, we will not only reduce energy and water use, we will also enhance
overall plant reliability while simultaneously increasing its efficiency,” said Mike Kleis, plant manager.
“We are thrilled to move forward on this project and to improve the plant’s long-term competitiveness.”

The control center will be housed in a new 10,000-square-foot building. Construction will begin later
this month.

Koch Nitrogen’s plant is located east of Enid, Okla., and employs about 100 people. The plant and its
affiliates produce and distribute fertilizer worldwide, producing and marketing about 10 million metric
tons of fertilizer products annually.
