WHEREAS, RCR wishes to purchase the Facility Products and to act as RDC’s exclusive distributor of the Facility Products under the terms and conditions set forth herein; and

WHEREAS, RCR is a major distributor of nitrogen products and has historically sourced up to 25% of its need from the Facility.

NOW, THEREFORE, in consideration of the premises and of the mutual covenants and obligations contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties agree as follows:

ARTICLE I

It is expressly understood and agreed that RCR may purchase Facility Products hereunder for its own account as well as for resale to its customers. In addition, RCR may accept deliveries of Facility Products from RDC on consignment in RCR’s terminals upon such terms and conditions as the Parties may agree.
