Rentech, Inc. Agrees on Coal Supply Terms With Peabody Energy

LOS ANGELES, March 6 /PRNewswire-FirstCall/ -- Rentech, Inc. announced today that it has signed a term sheet with Peabody Energy for the initial coal supply contract for Rentech Energy Midwest Corporation's (REMC) ultra-clean fuels conversion project in East Dubuque, Illinois. The coal will come from Peabody's Gateway Mine near Coulterville, Illinois. It will supply the REMC project, which will convert the existing natural gas-fired ammonia fertilizer facility into what the Company believes will be the United States' first Fischer-Tropsch and ammonia fertilizer production facility utilizing clean coal technologies.

The terms call for Peabody to provide up to approximately 7.2 million tons of Illinois coal commencing between August 2009 and January 2010 through December 2017. The parties may mutually agree to extend the term of the contract for an additional five years after that. The arrangement provides for a fixed price coal contract with standard industry escalation for five years, and a potential market based adjustment with a ceiling thereafter.. The terms are subject to approval of final definitive agreements by the parties.

"We are pleased to expand our relationship with Peabody beyond our Joint Development Agreement," said D. Hunt Ramsbottom, president and chief executive officer of Rentech. "Securing a cost-effective supply of coal represents an important development in completing the REMC project on time and budget. As a leading coal company, Peabody is well positioned to provide a reliable supply of coal to the Company. With this announcement today, as well as our construction progress at Rentech's Product Development Unit in Colorado, we are right on track with the commercialization of the patented and proprietary Rentech process. We believe our fundamentals have not changed in recent days and we are not aware of any business reason for the recent decline in our stock price," added Mr. Ramsbottom.

Rentech and Peabody previously entered into a Joint Development Agreement for the co-development of up to two potential clean fuels projects to be located on Peabody reserves. The projects would convert coal into ultra-clean transportation fuels using Rentech's proprietary Fischer-Tropsch process. The Joint Development Agreement represents Peabody's initial activities to develop clean fuels projects in the United States.
