Minnesota Pipe Line Company, LLC (MPL) owns a pipeline system that transports crude oil to the Twin Cities area of Minnesota. The MPL system has multiple lines running from Clearwater County to Dakota County, delivering crude oil primarily from Canada to the Marathon Petroleum and Flint Hills Resources refineries in St. Paul Park and Rosemount, Minn., respectively.

MPL’s pipelines are operated by Koch Pipeline Company, L.P., (KPL) a wholly owned, indirect
subsidiary of Koch Industries, Inc. KPL operates approximately 4,000 miles of pipelines that carry
approximately 1 million barrels of crude oil, refined products, and natural gas liquids daily. From its
Northern Division headquarters in Dakota County, Minn., KPL operates five pipeline systems and
employs over 50 people. For additional information on KPL, please visit www.kochpipeline.com.

In the fall of 2008, MPL completed construction of the MinnCan Project which increased the system’s
transportation capacity.

KPL, the operator of the MPL system, and MPL take proactive steps to ensure that health, safety, security and environmental issues are addressed as pipelines are planned, constructed and operated. KPL has an outstanding record of health and safety performance. In 2008, KPL received two awards acknowledging its commitment to safety.

In April 2008, KPL received the American Petroleum Institute’s Occupational Safety Award, the top
safety award for large pipeline operators, honoring the company for injury-free performance in 2007.
“Koch Pipeline employees are clearly dedicated to working safely,” said Peter Lidiak, API’s pipeline
director. “An injury-free year is a testament to that commitment. What’s more, our organization this year measured potential recipients against higher standards to even qualify for this award. It’s evident that Koch Pipeline also raised the bar as well.” The award is for the lowest OSHA recordable incident rate for both employers and contractors, and requires an operator to have documented safety requirements and performance criteria to be eligible for the award.

In September 2008, KPL was named one of “America’s Safest Companies” by Occupational Hazards
magazine. To be considered for this award, organizations must demonstrate innovative solutions to safety challenges, injury and illness rates lower than industry average, comprehensive training programs, a strong prevention process, good communication about the value of safety, benefits of the safety process, and other facets of safety responsibility. KPL received this award based on its performance relative to safety, health and loss prevention.
